Title: Improvements in or relating to two-state semiconductor devices
Inventor: GIBSON ALAN FRANK
IPC: H01L29/00
Filed: 1955-01-24
Abstract: 813,441. Semi - conductor devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 22, 1956 [Tan. 24, 1955], No. 2047/55. Class 37. [Also in Groups XL (b) and XL (c)] In a bi-stable device a first semi-conductor 1 having ohmic connections 2 and a rectifying contact 6 is arranged in series with a further semi-conductor 4 with ohmic connections 3, the contact 6 being biased so that the combination 1, 4 has two states in one of which the contact 6 conducts and in the other is reversely biased. The circuit is driven into one or other of the two state by illuminating the semi-conductors 1, 4 with optical systems 9, 10. Assuming the contact 6 to be reversely biased by battery 7 with respect to the semi-conductor 1, the illumination by light source 9 causes the resistance of the semi-conductor 1 to fall whereupon minority holes are injected as toward current into the semi-conductor. By this means the resistance of the serni-conductor 1 is reduced and a cumulative effect occurs until a second state is reached with the forward current limited by the diode resistance and the value of resistor 8. If the light source 9 is extinguished the circuit will remain in this state until a light source 10 illuminates semi-conductor 4 sufficiently for the potential opposite the contact 6 on semi-conductor 1 to rise so that it is reversedly biased. When this occurs the circuit restores to its original state and the light source 10 may be extinguished, the circuit remaining in this state until the light source 9 is again effective. The semi-conductors 1, 4 may be made as a single unit with a conducting layer separating the part 1, 4. Conveniently this layer may be carried beyond the edges of the semi-conductors to operate as a light shield preventing the illumination of one semiconductor by the light from the source associated with the other.

Abstract: 1372612 Antiskid braking systems TRW Inc 18 Jan 1972 [9 Feb 1971] 2412/72 Heading F2F An antiskid braking system includes an operator-operated master cylinder 29, a transmission driven skid control pump 22 forming a power source for braking pressure, a rotary power steering pump 23 forming an auxiliary source of power and a valve assembly including a throttle valve for regulating the application of pumpgenerated power to the brake motors and a valve 27 for connecting one or other pump to act as the main power source. When pressure is applied to the brake pedal 31 a push rod 30 moves a throttling valve 70 to close port chambers 73, 74 associated with the skid control pump 22 and steering pump 47, so that pressure is applied to the master cylinder. A shift valve 110, at speeds greater than 7 m.p.h. is moved by the difference of pressure between upstream and downstream of the pump 22 and if the steering pump pressure fails remains open until the wheel speed drops to 7 m.p.h. If the pump 22 failed valve 110 would be in the closed position and the throttled power steering output would be applied. In emergency, braking can be achieved manually through push rod 30, the valve elements forming a solid mechanical link.

Energy-absorbing elements; friction apparatus on permanent way. -Means for retarding the movement of a wagon travelling on rails comprises; a cataract.or dashpot which directly or indirectly interposes resistance to the travel of the axle or other part for a limited distance after which the wagon is freed. In the construction shown in Figs. 1, 2 and 3, a vertical dashpot carried below the level of the rails 13 by a fixed frame 3, includes a cylinder 1 and a plunger 2 having return connecting-rods 5 pivoted to the short arms of bell-crank levers 7. The long arms of the levers 7 occupy the position shown in full lines when the plunger 2 is in its highest position and that shown in dotted lines when the plunger is fully depressed and the lever swinging clear of the axle. Return springs 16 are provided. A one-way valve 10 allows free return movement and an adjustable needle valve 15 regulates the size of a throttling opening in the end of the plunger. In a modification, the cylinder is fixed in a horizontal position and its plunger is pivoted to a slidable member interposed in the path of the wagon axle but adapted to tilt clear of the axle at the end of the stroke. In a further modification, the cylinder is fixed in a slightly inclined position just below the wagon axle so that a small upward projection on the plunger contacts with the axle during the stroke, but moves downward clear of the axle at the end. The cylinder may be pivoted in an approximately horizontal position so that its plunger engages the wagon axle until it is tilted clear at the end of the stroke by a trip lever the end of which is depressed by the wagon wheels.

Title: Improvements in or relating to the production of laminated sheet material

Filed: 1944-02-16
Abstract: 579,344. Compound sheet materials. KREMER, A. Feb. 16, 1944, No. 2904. [Class 140] In producing laminated sheet materials of extended area by applying heat and pressure by means of a press to successive smaller areas of an assembly of adhesive-coated laminations, the laminations are so arranged that when they are undergoing treatment over one of the smaller areas in the press, there is a junction zone or zones between such area and the adjacent area or areas not in the press, the junction zone or zones having alternate laminations absent and being free of adhesive so that it or they cannot be prematurely affected by the heat from the press. The gaps in the zones may be temporarily filled during the pressing operations with removable spacer elements such as metal plates. After the pressing operation, and after removal of the metal plates if such have been inserted, the gaps in the zones are permanently filled by the insertion of pieces of material of the same nature as that from which the laminations are made. The pieces are accompanied with adhesive so that after a subsequent pressing operation the zones become continuous with adjoining pre-pressed areas. In one form, alternate laminations are continuous, corresponding to the whole length of the sheet, and being free from adhesive. A set of alternate intermediate, adhesive-coated laminations, of such size as to be wholly within the press area, is bonded to the 'full length laminations by treatment in the press. A further set of alternate adhesive-coated laminations is then slid into position and .a further treatment in :the press is carried .out. This operation is continued until the whole length of the sheet has been dealt with. The invention may be applied to the union of laminations by :adhesive applied directly to them, or by adhesive-impregnated sheets placed between them. The adhesive may be a thermosetting synthetic resin.
