Title: Semiconductor circuit having active devices embedded in flexible sheet
IPC: H05B33/00
Filed: 1968-10-19
Abstract: A circuit assembly e.g. a light amplifier comprises a layer 40 of electroluminescent grains 41 of ZnS activated by MnS, Cu, Cl embedded in a binder 43 of polyurethane in juxtaposition with a second layer 46 of photoconductive grains 47 of cadmium sulphide embedded in polyurethane as a binder. A contact layer 44 is vapour deposited on one side of layer 40 which is transparent to the radiation emitted by the grains 41 and on its opposite side a coating of vapour deposited contacts 45 in the form of islands and not transparent to the radiation are provided on layer 40. Similarly layer 46 is provided with a contact layer 49 and contacts 48, the latter being in ohmic contact with contacts 45. In operation a D.C. voltage is applied across terminals 54, 55 which is set up wholly across photoconductive layer 46. When radiation 57 is incident on layer 46 the resistance of this layer is reduced and the D.C. voltage is set up across electroluminescent layer 40 causing radiation 58 to be emitted. Reference is made to recombination, light sources, integrated circuit and three dimensional structures.

Patent ES-463345-A1 (ES)
Title: Recoil reducing and piston shock absorbing mechanism
IPC: F41A21/28
Filed: 1977-10-19
Abstract: A firearm recoil system that reduces the maximum recoil force felt by the shooter. The recoil force applied to the shooter's shoulder is interrupted by tapping off explosive gases produced by firing a cartridge and directing the gases into a gas cylinder to actuate a piston rearwardly and at the same time provide a forward force to the firearm opposite to the rearward recoil movement of the firearm. The rearward piston movement is slowed down by compressing air trapped within the cylinder and then venting the compressed air so that the remaining recoil energy in the piston is gradually phased out. This results in a substantially lesser peak or maximum shoulder force.

IPC: A01D41/14
Filed: 1979-06-29
Abstract: An automatic attitude control system is disclosed for a harvester having a crop pickup connected for pivoting about a transverse axis near the forward end of a crop-gathering head.

The control valve is actuated to lower the head when at least one of the switches in each of the "lower" groups is closed. A magnetic shorting bar is positioned between the "raise" and "lower" groups to prevent actuation of any of the switches by the magnetic actuator when the angle between the head and the pickup is within the preselected limits.
