Patent DE-2440411-A1 (DE)
Title: Instrument for measuring fuel consumption - instantaneous measurement of fuel consumption per unit distance travelled is continuously indicated
Inventor: ANDERS DIETRICH ING GRAD
IPC: G01F9/02
Filed: 1974-08-23
Abstract: Arrangement for continuous measurement of fuel consumption of a vehicle comprises:- a fuel pump, signal producer for fuel pump, tachogenerator producing signals proportional to the vehicle's speed, calculating block, and fuel consumption indicator. The latter produces quotients from signals proportional to the fuel passage and vehicle speed, and issues signals which are proportional to the instantaneous fuel consumption per unit distance travelled by the vehicle. The advantages of this system are that fuel consumption is continuously indicated without the need of further calculation which results in considerable saving in fuel by careful drivers and it is easily built in the vehicle.
Patent DE-2441845-A1 (DE)
Title: Pipe connecting appliance for installation - pipe ends swung together by tensioned swinging arms
Inventor: DORMAGEN GERHARD
IPC: F16L1/09
Filed: 1974-08-31
Abstract: Two pipe sections, particularly plastics pipes for house installation are each connected to a lever rod (1a, 1b) via a tensioning band or tensioning rope (2a, b). The pipe sections are provisionally aligned, and are then pushed into each other by pressing apart the two lever rods, which are in turn connected via a tensioning chain (3). A slight twisting of the sections is possible, to ease the connection of the pipes. Due to the adjustable tensioning bands, the appliance may be used for pipes of different diameters.

Title: Self-monitoring switch contact for switchgear - has fuse wire connecting isolated moving contact to its corresponding terminal
Inventor: SCHELLE JOSEF
IPC: H01H9/10
Filed: 1974-09-10
Abstract: The self-monitoring switch contact, for switchgear, has its moving contact (2) connected via an insulator (4) to its corresponding terminal (A) and electrically connected to this terminal by a fuse wire (5) chosen to melt at the required overload current. The stationary make and break contacts are connected directly to their respective terminals (B, C). The switch mechanism acts via a post (3) on the insulator of the moving contact. The advantage of this arrangement lies in the simple and reliable manner in which the contacts are protected against overload.

Title: Pressure control valve for windscreen washer - with sprung manually operated venting control to remove air locks
Inventor: KOENIG NORBERT ING GRAD
IPC: B60S1/48
Filed: 1975-04-09
Abstract: The washer line to the windscreen washer jets is fitted with a pressure control valve (1) which opens when the water pressure reaches a set level. This prevents leaks from the jets and ensures that a good jet control is achieved. Such valves operate with an elastic membrane (4) held against the valve seat (5) by a spring (6). If the washers are operated until air is drawn into the line then it becomes difficult to prime the pump again. To overcome this is venting control is fitted comprising a shaft (8) extending to the outside of the valve, which when pulled, pulls the spring back and allows the trapped ait to leave the line.

Title: Gyroscope stationary magnetic field error reduction - using laminated plates to cancel magnetic field of motor coil supports
Inventor: SCHULTZ PETER DR ING
IPC: G01C25/00
Filed: 1975-06-20
Abstract: A method of excluding the effects of external stationary magnetic fields, e.g. the earth's field, from the operation of a gyroscopic device, uses laminated sheets of magnetically sensitive material suitably arranged in the outer frame of the gyroscope drive motor. These cancel out the bar magnetic field of the motor winding supports which interact with the earth's field to produce the errors. The combined effect of the support plates and the additional laminates approximates to a circular or spherical magnetic characteristics which does not apply a turning moment to the gyroscope. The arrangement is economical and uses components made from rods and/or sheets whose length is longer than their cross-sectional width.
Patent DE-2528627-A1 (DE)
Inventor: HIRAI YUTAKA
IPC: C07C225/34
Filed: 1975-06-26
Abstract: The starting material is a hydrogenation product obtained by catalytic hydrogenation of 1-nitroanthraquinone in a reaction medium in the presence of a catalyst. The catalytic hydrogenation reaction product is treated with a solution of an inorganic base in water, an organic solvent or a mixture thereof. 1-Aminoanthraquinone is an important intermediate for the preparation of anthraquinone-based dispersions and vat dyes and pigments.

Title: Electrolytic filling of storage battery plastics container - using three phases, overfilling, pressurizing with air, and sucking out until required level is reached (NL 9.8.77)
Inventor: STEPPEK EWALD
IPC: H01M50/627
Filed: 1976-02-06
Abstract: The filling of a storage battery plastics container to a specified level is carried out by drawing the electrolyte into the container by suction. The container is overfilled in a first phase, pressurised with air, in the second, and in the third phase electrolyte is sucked out until it drops to the required level. The battery cell is first evacuated through the outlet bore (47) and the lead (49). Simultaneously, electrolyte flows in through the lead (50) and bore (46) until it reaches the level of the outlet bore (47). The container walls (79) are deformed in this phase as a result of the difference between the internal and external pressures.

Title: Vector-polarisation of ion beam by reflecting from surface - possessing high polish esp. of tensioned polished continuously moving band
Inventor: ANDRAE H JUERGEN PROF DR
IPC: G21K1/16
Filed: 1976-11-01
Abstract: An accelerated ions beam of the element which is to be polarised is directed at a very flat sweeping angle onto a clean, polished, plane surface, as the beam is reflected (scattered) from this surface it is vector-polarised by Coulomb interaction. The polarisation may be achieved by reflection at amorphous, microcrystalline or monocrystalline surfaces or at liquid surfaces. Specifically, a polished, plane surface may be produced by stressing of electrically conducting sheets, metal sheets metallised sheets or sheets with vapour-deposited metal surfaces, attained by tensioning them around shaped, polished rolls. Ions of all elements heavier than Be can be polarised in this way.

Abstract: Methane is prepd. by reacting CO with H2 in presence of a nickel contg. catalyst at 300-950 degrees C, the catalyst consisting of an acid function -free inert carrier based on a metallic oxide which has been calcined at a temp. above 1200 degrees C and on which are deposited 0.1-3% of an oxide of a gp 3,4 or 6 metal oxide stable at up to 950 degrees C and 5-25% relative to the prepd. catalyst of nickel oxide. The catalysts ensure the prodn. of methane at lower and higher temps. without the gas compsn. being dependent on the CO content. The reaction can proceed without the addn. of steam. The catalysts effect a far reaching stabilisation of the equilibrium and show a particularly long active period.
