Inventor: ZIMMERMAN SCOTT MOORE
IPC: G02F1/1335
Filed: 1996-05-17
Abstract: An improved backlight assembly comprising an array of apertures in close proximity to a light source, an array of tapered optical elements that have a light input surface area smaller than the light output surface area. Light rays pass through the apertures and are directed to the optical elements which transmit the light rays via internal reflection to provide a partially collimated light source. The light rays then pass through an array of microlenses that transmit the light rays via refraction and provide a substantially more collimated light source for the display elements of a display. The backlight assembly is advantageously used as a backlighting means for electro-optical displays, especially those designed for military and avionics applications.

Abstract: 1,008,005. Purifying sea-water by freezing. STRUTHERS SCIENTIFIC & INTERNATIONAL CORPORATION. Jan. 9, 1963, No. 1022/63. Heading F4H. Seed crystals of ice are added to sea-water and the latter is contacted with a vaporizable liquid refrigerant to freeze out ice on said seed crystals, the temperature difference between the sea-water and the ice crystals being maintained at less than 1‹ C. during freezing. As shown, pre-cooled sea-water is supplied through line 8 to a freezing vessel 1 to which seed ice crystals have been added. Vessel 1 contains an inverted Y-shaped baffle 9, which defines a water containing space L, and agitators 10 which cause the water to circulate around the vertical limb of the baffle. Liquid refrigerant is supplied to vessel 1 through lines 11 and gaseous refrigerant is withdrawn therefrom by a compressor 7 having a by-pass line 24 controlled by a valve 23 which is used to maintain an evaporating temperature of between minus 1À5‹ C. and minus 10‹ C. It is stated that at this temperature range and with agitation of the water during freezing the temperature difference between the ice-crystals and the seawater can be maintained at less than 0À1‹ C. Ice-brine slurry withdrawn from vessel 1 is decanted in a vessel 2 then passed to a centrifuge 3, where it may be washed with relatively dilute saline solutions and/or liquid refrigerant, from which the brine passes to a tank 15 and the ice to a suspension tank 4. In the latter the ice is mixed with liquid refrigerant from line 20 and the slurry is circulated by a pump 17 through a line 18 and a heat exchanger 27 in which it is heated by hot gaseous refrigerant from the compressor. Slurry is also withdrawn from tank 4 by a pump 21 and forwarded to a condenser 5 in which it is contacted by gaseous refrigerant from line 25. The resultant fresh water and liquid refrigerant are passed to a separator 6 from which the water is discharged as product and the refrigerant passes to vessel 1. The cold of the product water and the brine from tank 15 may be utilized in the process and the brine from decanter 2 is returned to vessel 1. The seed crystals supplied to vessel 1 may be formed from fresh water or by pre-freezing the incoming sea-water.

Title: Anti-skidding device for road vehicles
IPC: B60B39/00
Filed: 1940-01-22
Abstract: 535,146. Anti-skid devices. HANSEN, C. A. Jan. 22, 1940, No. 1287. [Class 108 (ii)] An anti-skid device comprises spikes 3 adapted to be released from the driver's seat so that they can swing downwards towards the road surface, each spike when thus released being supported clear of the ground in normal running by a wheel 5 which is mounted on a support 4 pivoted so that it can swing relatively to the spike in a transverse plane of the vehicle. Thus, when the vehicle side-slips it moves sidewise relatively to the wheel 5, which tends to run on in its own plane, and this movement causes the corresponding spike to dig into the road. The wheel support 4 is normally kept in a position determined by a stop 19 and a spring 18. Each spike 3 is pivoted at 2 in a box 7 and is normally kept in the fully raised position by a ratchet sector 8 on the spike engaged by a spring-loaded pawl 9 which is released by a cord actuated by the driver when he wishes to use the device. As long as there is danger of side-slip the pawls are kept retracted but when the device is not required the pawls are released and each engages one end of its sector 8. The vibrations of the vehicle in running cause the spikes to oscillate vertically, and each time a sector tooth passes the pawl the spike is retained in a higher position, so that all the spikes gradually rise automatically until they abut against stops 20. In a modification a friction ratchet sector and eccentric pawl are used instead of the toothed ratchet.

Abstract: 770,234. Echo-sounding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 19, 1955 [Jan. 18, 1955], No. 1466/55. Class 118 (2). The change in speed for two different ranges of a recording echo-sounder is obtained by the mere reversal of the direction of rotation of an electric drive motor. A reversible electric motor 3 has two drive paths to the stylus drive shaft 1, the worm 4 and wheel 5 being used in each case. For one direction of rotation of the motor the wheel 5 drives the shaft 1 directly through the medium of a free-wheel device 6. In the reverse direction of rotation of the motor this drive is ineffective, but a gear 7 fast with the wheel 5 by a sleeve which is free on the shaft 1 drives gears 8, 9, 10 and 11. By a second free-wheel device 12 the gear 11 drives the shaft 1 in the same direction as before but at a different speed. The free-wheel devices are preferably of the jamming ball- or roller type (Fig. 2, not shown). The motor 3 may be reversed directly by a switch or indirectly by means of a relay.
