Title: Mine face hydraulic servo motor control valve - has spring biased blocking piston with loose fitting stem
Inventor: GRAEWE FRIEDRICH
IPC: E21D15/51
Filed: 1975-08-19
Abstract: The control valve arrangement is for a hydraulic servo motor to control hydraulic cylinders for mine facing supports. The main control valves of the cylinders are controlled by servo valves, which can block the fluid supply to the main valve. The stop is spring biased onto a valve seat. It lifts off when the servo valve is actuated and frees the fluid supply. The blocking element (1.1) has a stem (1.7), which has enough free play to allow fluid to pass it. It projects into a channel below the valve seat, leading to a pump. The stem is part of a spring plate. A helical spring (1.5) supports itself with one end of the spring plate. The other spring end supports itself on the collar, and surrounds the stem.

Title: Otto machine indirect fuel injection - has injector jets built into inlet valve guides and inlet valve is closed hydraulically
Inventor: HEINRICHS WALTER
IPC: F01L9/12
Filed: 1975-10-21
Abstract: Fuel injection should take place via at least three axial bores made in the inlet value guide bush so that a spiral air fuel mixture is formed which readily ignites to give a weak exhaust emission. A piston (13) co axial to the inlet valve central axis (12) is actuated by the closing cam (14) on the one side and subjected to lubrication oil, transfer means and the opening piston (16) on the second side. The inlet valve is opened by the overhead cam in the usual manner and closed by a combination of oil pressure and compression. The noise level is reduced and valve play is unnecessary.

Title: Separator to remove liquids from gases - has reentrainment pipe between outlet venturi throat and liquor sump
Inventor: SCHULTZE ERICH
IPC: F25B40/00
Filed: 1976-01-21
Abstract: Trap to remove liq. from vapours and gases can use vertical or horizontal vessels and can be with or without means of providing heat transfer. A small section tube is mounted in the outlet branch from the vessel, the discharge being in line with the direction of flow. This outlet can have various shapes but generally takes the form of a venturi. The pipe clips into the collected liq. and provides a continuous entrainment of this as a fine mixt., dispersed in the outlet gas stream. To enhance the separation of the trap and increase its effectiveness as a foam breaker, an impingement baffle can be located between the inlet and the outlet having a T-shaped cross-section. TRaps can be constructed from two or more vessels connected in parallel. Used for use on refrigerant systems. The trap is designed to hold liq. surges which tend to occur from time to time esp. at start up of the compressor, the trap being on the vapour inlet. By mounting the suction tube directly in the throat of the outlet and aligning it with the flow, the full effect of the dynamic and static suction heads are obtd. which overcomes most of the disadvantages of existing reentrainment methods.

Title: Incinerator for combustibles tending to cause tar deposits - ensures complete oxidation of hydrocarbons and efficient heat exchange
IPC: F23G7/10
Filed: 1976-03-02
Abstract: A process for handling combustible materials generating gases, the hydrocarbon contents of which condense as tarry deposits when they are cooled below their dew point, ensures that sufficient oxygen is provided to burn completely the entire content of combustible matter. The combustible is transferred to a treatment chamber in the form of blocks, logs, bales, bundles, sheafs, otherwise stacked loose material, or pressings and pellets, etc and heated to degasify and distill it while introducing some oxygen to bring about a partial combustion. The gas fractions obtd. are throughtly mixed and sepd. from the stored combustible, in a stream to which the necessary oxygen for complete combustion is supplied. Makes it possible to exploit fully and economically the heat energy resources available is waste materials such as straw, scrap timber, etc.

Title: Hydraulically driven shipboard submersible pump - has chamber between motor and pump under gas pressure to prevent leakage (NL041176)
Inventor: BLEIJENBERG GERRIT WOUTER
IPC: F04D29/10
Filed: 1976-04-29
Abstract: The pump has a hydraulic motor (1) with oil supply and discharge connections (22, 23). The motor shaft (8) is extended downwards and carries a centrifugal pump impeller (7) the discharge (6) of which is carried up to the above the top (19) of the liquid container in which the pump and motor assembly is submersed. A chamber (9) in the assembly casing (4) separates the gland (11) of the motor and the gland (10) of the pump. Air under pressure is admitted from a pipe (16) through a non return valve (17) into this chamber and escapes through a smaller outlet (18). The air pressure is higher than that of the oil in the motor and that of the liquid in the pump and thus prevents leakage through both glands.

Title: Honing strip for multi-shell honing tool - uses front side clamp to fix honing strips in longitudinal grooves of shells
Inventor: HENNINGHAUS FERDINAND
IPC: B24B33/08
Filed: 1976-05-03
Abstract: The shell is fitted with honing strips for multi-shell honing tools which consist of a cylindrical body and at least two shells fitted externally to the body and arched in cross-section. These have honing strips which are fitted in longitudinal grooves on the shell outside. A guide- and setting device allows the shells to be brought out of an output position on the body into an extreme spreader position as well as into intermediate positions radially spaced from the body. They can also be returned into the output position. A front side clamp fixing holds the honing strips in the longitudinal grooves (6) of the shells (1). Each longitudinal groove (6) is bonded by a front bridge (2) and a rear bridge (3). One of the two bridges has a threaded longitudinal bore (9) to accept a screw, while the other bridge (2) serves as a thrust bearing when the honing strip (11) is inserted into the longitudinal groove (6).

Title: Spacer for rock anchor - with pear-shaped body of hard PVC with tubular ends
Inventor: EICHELE HUBERT
IPC: E02D5/74
Filed: 1976-07-23
Abstract: Spacer for rock anchor comprises a pear-shaped basket-like hard PVC body with tubular end sections.

Patent DE-2637859-A1 (DE)
Inventor: HEMPELMANN WILHELM
IPC: G21F9/00
Filed: 1976-08-23
Abstract: In the device, the mixture constituents are put directly into the drum, the concrete being hardened directly therein after mixing thoroughly. The device consists of a shielded and alpha-tight cell (7) in which the radioactive wastes are handled, as well as of feeder devices for the empty drum (21) to the cell. The aim of such a device is to be able to process medium-level radioactive wastes as well, the idea also being to process plutonium, and, above all, the outside of the drums remaining free from contamination. The device permits this due to the fact that the drum (21) can be pressed from below against the cell and its charging opening can be connected to a further opening (23), situated in the cell floor, of an alpha-tight double-cover system (33). Further advantageous characteristics of the device consist in that two cell openings (23, 24) are provided in the cell floor (25) for the simultaneous connection of two drums (21, 22), and in that each opening (23, 24) is respectively assigned a double-cover system (33, 36) in the cell. In this arrangement, a swivelling device can be used to raise each double cover (33, 36) axially out of the opening (23, 24) and subsequently swivel it to the side. <IMAGE>

Title: Signal storage system in memories, counters and shift registers - has remanence coil and intermediate store which reads signal in coil in event of supply voltage failure
Inventor: LAU WALDEMAR ING GRAD
IPC: G11C14/00
Filed: 1976-09-10
Abstract: The method uses a remanence coil decoupled from the main store and magnetisable in accordance with the main store state. The coil has no effect in normal operation, so that an intermediate store takes over, when supply voltage is switched off. The signal stored in the coil as residual magnetisation is taken into an intermediate store by application of reading or interrogation pulses. It stores the signal for its writing in the main store until the reading-interrogation phase is ended.
