Title: Sheet set sorting equipment - has logic control to form additional virtual compartments for sheets in excess of compartment capacity
Inventor: CLARK GARY ALAN
IPC: B07C3/00
Filed: 1978-11-07
Abstract: The sheet sorter has K compartments each with a capacity for a maximum of L sheets, and a logic control system. A first detector supplies to the system a number N of sheets contained in the sets, and this number N is then compared with the maximum capacity L of the compartments. Where N exceeds this capacity, a signal is given. This causes H virtual compartments to be formed, comprising J adjacent ones, so that the total capacity J x L of each virtual compartment is at least equal to N. H first sets of sheets are then directed into the H virtual compartments.

Title: Dynamic flying piston press - convertible to static hydraulic press by high pressure fluid admission to press piston
Inventor: KEILHOLZ FRIEDRICH DR ING
IPC: B21J9/12
Filed: 1978-11-08
Abstract: A flying piston press for drop forging or press operations has a compressed air actuated drive mass which is hydraulically coupled to the press piston and moves it forward by immersion in the coupling field. The supply line for the latter can be connected, instead to a hydraulic fluid at adequate pressure (50 bar) to preload the drive mass, to a hydraulic medium of much higher pressure (250 bar). This allows a ready conversion from the dynamic press operation as a flying piston press to the static press force of a normal hydraulic press so that the machine is more universally applicable.

Title: Safety cut=out switch for vehicle electrics - has impact sensors linked to pressurised isolator on main battery lead
Inventor: KIEDAISCH ULRICH
IPC: B60K28/14
Filed: 1978-12-20
Abstract: The impact safety switch is for a vehicle and has a pressurised switch linked to a gas pressure reservoir as well as to special detectors which are broken on impact. This releases the pressure and causes the switch to open the connection to the battery and hence isolate the electrics. The isolator switch has two spring loaded pistons held together by the gas pressure. The sensors can be glass covered with a plastic film, to prevent splinters or any other fractured material. The gas reservoir is filled via a non-return valve, and can be linked to the vehicle pneumatic circuit. A bypass switch (6) is fitted to allow the vehicle to be removed after a collision. The isolator switch prevents any fire started on impact due to split fuel and live electrical circuits.

IPC: G11C16/04
Filed: 1978-12-29
Abstract: A volatile semiconductor memory, consisting of MOSFETs on a chip together with the peripherals is produced by applying a local silicon oxidation (Locos phototechnique). Four silicon dioxide layers and three silicon nitride layers are deposited in turn. The finished semiconductor memory consists of a p-type silicon chip (1) with a first SiO2 (2) from which the first Si3N4 layer has been removed by etching. Thick oxide layers (4) have been converted from parts of the layers (2) by a LOCOS technique. Polysilicon layers (5) protect the locations for gates. Phosphorous doping produces n-type layers(6). A second oxide layer (7), temporarily masked by a nitride layer, is partly etched to apply a third oxide layer (10) of 3 nm thickness and a third nitride layer (11) of 50 nm thickness. An Al layer (12) covers this double insulation, followed by a final passivating layer (13) of plasma nitride.

IPC: D06P3/62
Filed: 1979-09-24
Abstract: A novel process for the continuous dyeing of cellulose textile material with anionic substantive dyes is disclosed. The process consists initially in applying to the cellulose material an aqueous liquor which, in addition to the dye, contains (A) 2.5 to 15 g/l of an etherified N-methylolmelamine, (B) an acid catalyst and at least one of the components (C) an anionic surfactant, (D) a non-ionic surfactant and (E) an organic solvent which boils above 140 DEG  C.
