Title: Pulse duration prolonging circuit - is for digital control or information pulses using delay network
Inventor: HANKE GERHARD DIPL ING
IPC: H03K5/06
Filed: 1973-11-15

Title: Pressure control system for servo steering - has locking system for control valve regulating spring so that power failure is compensated
Inventor: STRAUFF GUENTHER
IPC: B62D5/06
Filed: 1973-12-13
Abstract: The main patent describes a complete system with two servo valves that alternate connection of a servo motor to either a pressure source of a pressure outlet and a mechanical feedback system for the movement of the servomotor. The servo valves are pressure regulated with the applied pressure being counteracted by a regulating spring. In this addition there is at least one locking position where the spring is held. This is set for a specified value of operating force. If this force is not exceeded, a percentage of the force is supplied by the servo system itself, reaching a maximum where the power connection between operating member and regulating spring is broken. The operating member has position screws for adjustment.

Title: Domestic water supply press. reduction valve - has a moving cylindrical valve seat balanced by water press.
Inventor: VOLLMER RUDOLF
IPC: G05D16/06
Filed: 1974-02-16
Abstract: The valve has a cylindrical valve seat (19) attached to a co-axial rod (11) which is loaded by a spring (8) so as to reciprocate normally to the flow to effect opening and recoil closure. The rod passes axially through a valve disc (12). A membrane (7) surrounds the junction between rod and spring to form a pressure chamber. The seat and disc are contained within the chamber (1) and the direction of fluid flow is such that the valve is urged closed. The area of the surfaces (26), (27) of the valve acted upon by upstream fluid pressure is the same as the area (28) of the valve seat acted upon by fluid pressure in the opposite sense.

Title: Passive metal electrode for electrochemical cells - made with porous titanium/titanium oxide base coated with fused titanium and noble metal
Inventor: RUBISCH OTTMAR DIPL CHEM DR RE
IPC: C25B11/04
Filed: 1974-03-16
Abstract: An electrode is manufactured by fusing a mixt. of Ti and TiO powders to give a base matl. of TiOx where x is between 0.25 and 1.5. This fused mixt. is porous and so fairly light and is coated with a layer of titanium powder fused again to give good adherence, then finally coated over at least 5% of its surface with a noble metal, e.g. platinum. The pores of the base matl. act as gas evacuation passages. To keep the bottom of the electrode free of gas bubbles, inclined channels are formed which allow the gas flow to the surface of the cell. The electrode can be used in e.g. mercury or diaphragm cells for prodn. of chlorine; for the oxidn. or org. prods. and for cathodic protection. The electrode is not consumed during the electrolysis but offers little electrical resistance. Helps prevent build up of gas bubbles on the surface which affect efficiency and the rough surface allows greater current density to be used.
Patent DE-2416179-A1 (DE)
Title: Meter for gaseous water vapour content - uses lithium chloride on insulating base between two electrodes
Inventor: BARTHOLL HERMANN DIPL ING
IPC: G01N27/12
Filed: 1974-04-03
Abstract: The base maerial is applied on a cylindrical supporting element, insulated at least on its outer surface. Inside it has at least one heater and at least one temperature measuring device; Conduction testing electrodes are ring-shaped and placed on the support; or at least one heater and at least one temperature measuring device are provided in the support wall. A special advantage of this arrangement is that the heated stream does not flow through the electrolyte but is determined by the conductivity of the lithium chloride layer. This avoids electro-chemical displacements and local over-heating. The measuring device gives a signal to control the heating which is so ordered that the conductivity of the lithium chloride sector is maintained essentially constant.

Title: Shothole drifter chisel shank lock - has bush lugs driven into groove in drill tube for twisting and locking by spring insert
Inventor: SUBAREW ANATOLY IWANOWITSCH
IPC: B25D17/08
Filed: 1975-06-23
Abstract: The chisel shank lock for percussive drifters used in shot and blasthole drilling in the mining industry consists of a bush fitted onto the drill tube. For a secure hold, the rear endwall of the bush (8) has radial lugs (11) which fit into open ended and dead-end longitudinal grooves with associated cross linking grooves machined in the drill tube (4). The lugs are forced along the grooves into the cross grooves (12) when pressure is applied to the bush from inside (8, 9). When the bush is twisted round ints axis, the lugs move over into the dead-end grooves and engage these under power of a spring loaded member inserted between the bush and tube (4) which thus locates the bush in the operating position.
