Patent DE-2639659-A1 (DE)
Title: Indirect continuously injected fuel system - has temp. dependent cold running phase compensators
Inventor: ZEBLI ROLAND-DETLEV DIPL ING
IPC: F02D41/06
Filed: 1976-09-03
Abstract: The fuel injection system is mechanical and continuously working requiring no drive from the engine. Induction air is measured by a flap pivoted upstream to the throttle flap (12). Fuel is then distributed to individual cylinders by a fuel volume distributor (5a) to the injectors (7). The induction air flap (5b) and fuel volume distributor (5a) are integrated (5). Increased friction during cold running phases is compensated by an additional air slide (10). The slide is located in a throttle flap (12) by-pass (14). The slide cross section can be varied by a temp. dependent aperture. The fuel condensation losses on the cold induction pipe walls are compensated by an electro-magnetic start valve (8). The start valve has a thermo time switch to limit the valves opening duration. Under normal working conditions both cold phase running system are closed. The start valve causes the air metering flap to pulsate.

Title: Front trim flap for supersonic aircraft - with spearhead shape and pivotted leading edges for trim and height control
Inventor: KANIUT HERBERT ING GRAD
IPC: B64C3/00
Filed: 1976-09-21
Abstract: The front of the fuselage is fitted with a trim plane with a spearhead shape of tapering front and trailing rear edges. This reduces supersonic drag to acceptable levels. The front sections of the plane are pivotted to act as trim and height. The pointed front section is the height control flap a second section, behind the first, acts as a trim flap. The plane is widest at a point where the front edge of the windscreen starts, and some way behind the trim flap. The design optimises drag with steering control, so that an effective control is obtained over a wide range of from subsonic to supersonic.

Title: Location of people buried by avalanche - uses radio transmitter on victim, and portable receiver producing audio signal to guide rescue team
Inventor: MUELLER RUDOLF PROF DR
IPC: A63B29/02
Filed: 1977-01-28
Abstract: A method of locating people who have been buried alive e.g. by avalance involves use of an active probe. It uses a transmitter producing an electromagnetic field which is received by a receiver using a ferrite antenna. The amplitude of the received signal gives the distance from the transmitter on the buried person to the search receiver. The received signal is fed to an amplitude to frequency converter giving an audio signal which is used to guide the searcher to the transmitter.
Patent DE-2709158-A1 (DE)
Title: Vacuum door lock for motor vehicle - has two part operating rod with pivoted hook to prevent manual unlocking
Inventor: ANDRES RUDOLF
IPC: E05B65/38
Filed: 1977-03-03
Abstract: The vacuum unit (1) actuates the lock through two rods (2, 4). A plate (3) on the lower rod has a slot (5) in which the hooked end (7) of the upper rod (4) slides. When the lower rod is drawn downwards for locking, the hook engages with the top of the slot and presses a pivoted hook (9) into an aperture (14) in the bracket (13). Manually applied tension in the upper rod (4) will not release the lock until the vacuum is released, when the spring (10) withdraws the hook (9). The system achieves positive prevention of manual unlocking not attained by the vacuum alone.

Title: Electric heater safety circuit - has diode in parallel to triac in series with heating conductor
Inventor: ZUERKER HERMANN
IPC: H02H3/02
Filed: 1977-05-05
Abstract: The safety circuit for an electric heater employs a triac (Tr) in series with the heating conductor (RH) across the AC supply. A resistor (RN) of low ohmic value in comparison to the heating conductor (RH) is connected in series with a diode (D2) across the latter. A control oscillator (SG) synchronised with the AC supply is coupled to an ignition signal generator (ZG) for the triac, monitoring the half waves of the AC supply corresponding to the direction of conduction of the diode (D2). An ignition signal for the triac is blocked during these half waves. A controlled switching unit (TG) receives the output of several monitoring devices (U1 .. U4) and is coupled between the control oscillator (SG) and the ignition signal generator (ZG).

Title: Conveyor track for cases of bottles - has belt rising above level of supports when operating, lowered when at rest
Inventor: BRUDER HARALD
IPC: B65G47/26
Filed: 1977-06-20
Abstract: The conveyor track system is for cases with filled bottles. They are moved along a support surface by a friction drive system subdivided into several successive sectors in which the conveyor can be independently operated and controlled. The conveyor track includes sensor links positioned along the track which can switch off the drive system in the appropriate sector whenever a case stays longer within the sensing area than during normal movement. The conveyor is operated by a conveyor belt (3) extending between support rails (6) adjoining it on both sides on which the cases stand. The conveyor belt, when operating, rises slightly above the level of the support rails and when stopped is lowered slightly below that level.

Title: Pipeline cleaner for oil cracking plant - directs jets of liquid onto pipe bore at pressure of 600 bars
Inventor: RYTTER MOGENS LARSEN
IPC: B08B9/053
Filed: 1977-10-18
Abstract: The layer of coke (2) which forms in the bore of the pipe line (1) of an oil cracking plant can be removed by jets of liquid at a pressure of 500-600 bars. The jets are directed from nozzles (15) screwed into fittings (13) which are in turn screwed into the cylindrical body (3). The body (3) is supported by a tubular carrier (4) which has radial legs (5) forming part of guide bars (6). The high pressure fluid is supplied from a flexible hose to the central hole (11). The device is pushed along the pipe and cuts longitudinal grooves in the coke layer (2). It is then moved over the same area but with a rotary motion so that a screw thread is cut in the coke layer. The layer is thus broken up and washed away by the fluid.

Title: Stable, dried aluminium hydroxide gel - prepd. by drying gel from non-aq. solvents
Inventor: HEM STANLEY LAWRENCE PROF
IPC: C01F7/02
Filed: 1977-11-10
Abstract: In the drying of aq. Al(OH)3 gel to afford a stable dried Al(OH)3 meeting USP (18th revision) specifications, aq. liq. is replaced by an H2O-miscible non-aq. solvent (I), and the gel is then dried to afford an acid-reactive, dried amorphous powder contg. 50-56.8% Al2O&.

Title: Hollow chain connector bolt - is slotted tube with threaded taper plug each end and slot filled with wax
Inventor: MENKHOFF KARLHEINZ
IPC: F16G13/06
Filed: 1978-04-27
Abstract: The hollow end bolt for a large chain uses a lengthways slotted tube with a cone inside both ends in which at either end an outer-threaded cone (2) is fitted. As this latter cone is screwed in with the aid of an appropriate tool, the outer dia. of the tube enlarges, causing it to draw firmly into the chain component. The inner cone has a ring (4) which projects inwards, and this prevents the outer threaded cone, once inserted, from becoming detached. The lengthways slot in the tube, up to a central opening, is closed by sealing wax (5) so that the hollow space (6) inside can be filled with oil for lubrication of a bush fitted around the bolt.

Title: Intelligibility aid for deaf and dumb - converts keyboard entry into signals for transmitting via telephone line to remote user with visual display
Inventor: HARMS ROLF
IPC: H04M11/06
Filed: 1978-07-29
Abstract: The intelligibility aid fits onto a normal telephone handset and transmits and receives signals (rather like a teleprinter) which can be displayed optically as letters or numbers. Two deaf and dumb people can therefore communicate via the public telephone network. Coded messages may also be sent. The user enters his word via a keyboard.
