Question

Q. What do bullet-proof vests, fire escapes, windshield wipers, and Laser printers all have in common?

Answer 1

They were all invented by women

Answer 2

Well it appears that Bullet proof vests were invented by a woman, Windshield wipers were patented by a woman, laser printers were invented by a man and fire escapes have got no reference I could find to the inventor other than a black man who invented a portable version of existing escapes.

Answer 3

They all Zig Zag, left to right bullet proof vests are "woven" like that?

Answer 4

All safety and helpful items


When a handgun bullet strikes body armor, it is caught in a "web" of very strong fibers. These fibers absorb and disperse the impact energy that is transmitted to the vest from the bullet, causing the bullet to deform or "mushroom." Additional energy is absorbed by each successive layer of material in the vest, until such time as the bullet has been stopped.

Because the fibers work together both in the individual layer and with other layers of material in the vest, a large area of the garment becomes involved in preventing the bullet from penetrating. This also helps in dissipating the forces which can cause nonpenetrating injuries (what is commonly referred to as "blunt trauma") to internal organs. Unfortunately, at this time no material exists that would allow a vest to be constructed from a single ply of material.

Currently, today's modern generation of concealable body armor can provide protection in a variety of levels designed to defeat most common low- and medium-energy handgun rounds. Body armor designed to defeat rifle fire is of either semirigid or rigid construction, typically incorporating hard materials such as ceramics and metals. Because of its weight and bulkiness, it is impractical for routine use by uniformed patrol officers and is reserved for use in tactical situations where it is worn externally for short periods of time when confronted with higher level threats.

Chicago inventor, Daniel McCree invented a portable fire escape that was designed for the interior of buildings. McCree's fire escape could roll and had a carriage that could be raised and lowered. It was intended to be part of a building's own fire prevention equipment and stored on location.

Prior to the manufacture of Henry Ford's Model A, Mary Anderson was granted her first patent for a window cleaning device in November of 1903. Her invention could clean snow, rain, or sleet from a windshield by using a handle inside the car. Her goal was to improve driver vision during stormy weather - Mary Anderson invented the windshield wiper.

During a trip to New York City, Mary Anderson noticed that streetcar drivers had to open the windows of their cars when it rained in order to see, as a solution she invented a swinging arm device with a rubber blade that was operated by the driver from within the vehicle via a lever. The windsheld wipers became standard equipment on all American cars by 1916.

The automobile gave women ample opportunity for invention. In 1923, of the 345 inventions listed under "Transportation" in the Women's Bureau Bulletin No.28, about half were related to automobiles and another 25 concerned traffic signals and turn indicators. Among these inventions -- a carburetor, a clutch mechanism, an electric engine starter, and a starting mechanism.

During the 1930s, Helen Blair Bartlett developed new insulations for spark plugs. A geologist by training, her knowledge of petrology and mineralogy was critical in the development of innovative uses of alumina ceramics.

Another woman inventor named Charlotte Bridgwood invented the first automatic windshield wiper. Charlotte Bridgwood, president of the Bridgwood Manufacturing Company of New York, patented her electric roller-based windshield wiper called the "Storm Windshield Cleaner" in 1917. However, her product was not a commercial success.

In 1953, the first high-speed printer was developed by Remington-Rand for use on the Univac computer.

In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox, the foundation technology for laser printers to come.

The original laser printer called EARS was developed at the Xerox Palo Alto Research Center beginning in 1969 and completed in November, 1971. Xerox Engineer, Gary Starkweather adapted Xerox copier technology adding a laser beam to it to come up with the laser printer. According to Xerox, "The Xerox 9700 Electronic Printing System, the first xerographic laser printer product, was released in 1977. The 9700, a direct descendent from the original PARC "EARS" printer which pioneered in laser scanning optics, character generation electronics, and page-formatting software, was the first product on the market to be enabled by PARC research."

According to IBM, "the very first IBM 3800 was installed in the central accounting office at F. W. Woolworth’s North American data center in Milwaukee, Wisconsin in 1976." The IBM 3800 Printing System was the industry’s first high-speed, laser printer. A laser printer that operated at speeds of more than 100 impressions-per-minute. It was the first printer to combine laser technology and electrophotography according to IBM.

In 1992, Hewlett-Packard released the popular LaserJet 4, the first 600 by 600 dots per inch resolution laser printer.

In 1976, the inkjet printer was invented, but it took until 1988 for the inkjet to become a home consumer item with Hewlett-Parkard's release of the DeskJet inkjet printer, priced at a whopping $1000.

Answer 5

1975 3 Days of the Condor, Robert Redford's character, a CIA analyst, confronts his extra advantageous, performed by skill of Cliff Robertson. undergo in suggestions, this grew to become into 1975: Turner (Robert Redford): "can we've plans to invade the middle East?" Higgins (Cliff Robertson): "Are you loopy?" Turner: "Am I?" Higgins: "seem, Turner..." Turner: "can we've plans?" Higgins: "No. easily no longer. we've video games. it fairly is all. We play video games. What if? what number adult males? What could it take? Is there a extra much less high priced thank you to destabilize a régime? that's what we are paid to do." Turner: "bypass on. So Atwood merely took the interest too heavily. He grew to become into incredibly going to do it, wasn't he?” Higgins: "It grew to become right into a renegade operation. Atwood knew fifty 4-12 could in no way authorize it. there grew to become into no way, no longer with the warmth on the corporate.” Turner: "What if there hadn't been any warmth? Supposing I hadn't got here across a plan? Say no one had?" Higgins: "different ball interest. in actual fact there grew to become into no longer something incorrect with the plan. Oh, the plan grew to become into ok. The plan could have worked." Turner: "Boy, what's it with you human beings? you think of no longer getting caught in a lie is the comparable element as telling the fact?" Higgins: "No. it is elementary economics. right this moment it is oil, genuine? In 10 or 15 years - nutrients, Plutonium. and probably even faster. Now what do you think of the each physique is gonna want us to do then? Turner: "Ask them."
