Title: Lubricating oil system for IC engine - has auxiliary oil tank to replenish sump when level falls
Inventor: GLIESE KLAUS-DIETER
IPC: F01M11/06
Filed: 1974-03-19
Abstract: The engine has a sump holding lubricating oil at the bottom of the cylinder block. Oil is circulated by a pump and returns by gravity. An auxiliary oil tank is mounted in a suitable position alongside the engine or within the engine housing and is connected to the sump in the cylinder block by a pipe which contains an electromagnetic solenoid valve. The engine sump has an oil level meter which operates the solenoid valve when the level in the sump falls. A warning light is illuminated when the auxiliary tank is empty but as the sump is still full at this time the engine is not damaged if there is a delay before the oil is replenished.

Title: Concentrated hop powder - method comprises detection of certain components in waste during powder production
Inventor: WACHTER ROLF
IPC: G01N33/02
Filed: 1974-05-17
Abstract: In the production of concentrated hop powder a mixture of pulverised leaves and stalks is found among the wanted lupines. This mixture is taken to a sifting stage. The spectrum of electromagnetic waves emitted by these components is measured. Only characteristic wavelengts are measured. A part of the waste flow is branched off and its components are excited into oscillations. Thermactinic radiation emitted by the components is then measured; or radiation reflected from the components is measured. Waste is irradiated by a wavelength which is absorbed and/or transmitted only one of the components.

Title: Traffic decoder for car radios - has ccts hunting code freq switch to reduce level of first signal to avoid startling driver
Inventor: MEINHOLT ALBRECHT DR ING
IPC: H03G1/02
Filed: 1974-05-17
Abstract: The traffic decoder, for radio receivers in vehicles, has a regulated shunt circuit bridging the switch controlled by the code frequency. This shunt circuit allows the received level difference between 'off' and 'switched through' to be adjusted arbitrarily. The shunt circuit consists of a variable resistor. The difference may also be adjusted by altering the gain of the audio amplifier in conjunction with the switch's position. The advantage of reducing the amplitude of the first incoming signals in this way is that they do not then startle the driver and cause him to make mistakes.

Title: Two stage pressure regulator - with provision for full flow from one circuit to another has pilot stage to move main spool
Inventor: HAUSER MANFRED ING GRAD
IPC: G05D16/10
Filed: 1974-07-12
Abstract: A pressure regulator of a two stage design control pressure in two output circuit lines and provides a free return flow one circuit through the regulator to the other. When flow passes from inlet (14) to outlet (15) across a restriction formed in a main spool (17), the output pressure in a channel (44) operates on one side of a pilot spool (36). Pilot spool reacts to the pressure difference between inlet (14) and outlet (15) together with reference spring action (43) to regulate the discharge to tank (23) to maintain constant pressure. When reverse flow occurs into port (15) the pilot spool moves against stops (45) to block dumped flow (23). The main spool is then pressure balanced and the bias spring (19) provides a full flow connection from one circuit (26) to the other (24).

Title: Carburettor for IC engine - giving reduced carbon monoxide content in exhaust during idling with air bypass line
Inventor: SAKAI JIRO
IPC: F02M23/02
Filed: 1974-09-18
Abstract: Carburettor for i.c. engines has an air pipe leading from the air filter inlet directly to the mixing chamber. This passes through a spacer located below the mixing chamber and its end is bent upwards into the normal air flow, discharging near the normal butterfly throttle. There is a flow regulating valve mounted in the line. The carburettor is of use on i.c. petrol engines, esp. for motor cars. Most engines at low engine revs., particularly when idling, receive a very rich mixture from the carburettor which causes increased atmospheric pollution. In particular there is a marked rise in CO emission. This problem is overcome by increasing the amount of air fed into the mixture during the idling condition.

Title: Energy from nuclear reactor converted to gas for distribution - gas burns to methanol which is recovered for re-conversion
Inventor: WEISSENBACH BERTRAND DR PHIL
IPC: G21D9/00
Filed: 1974-12-05
Abstract: Heat energy, e.g. from a nuclear reactor, is to be converted to chemical energy in a gas suitable for distribution through the existing mains; the liq. combustion product is returned through the same mains for re-processing, so recovering the carbon and keeping the economics independent of the price of coal. The simplest reaction described, CH3OH + energy CO +2H2, proceeds in a closed circuit uncontaminated by atmospheric oxygen. Alternatively, a second stage of processing: (CO+2H2)+H2 right arrow CH4+H2O, gives high-calorific-value methane for distribution and allows losses of carbon in the circulation to be made good from natural gas. At the consumer's end, CH4+1/2O2-energy CH3OH, which is returned through the gas mains as before. The corresponding reactions with C2H5- or C3H7- in place of CH3- can be utilised in the same way.

Title: Ringless spinning of textile fibres - using a rotating multi vane wheel with a centre opening which forms a yarn of the fibres fed onto it
Inventor: SAWELIEW ALEXANDR IWANOWITSCH
IPC: D01H4/28
Filed: 1975-02-17
Abstract: A machine for ringless spinning of textile fibres comprises a rotor mounted on a spindle and a passage through which fibres are fed to the rotor. The rotor is shaped like a multi vane wheel which upon rotation creates an air stream for conveying the fibres. The rotor includes a disc which collects the fibres and forms a yarn of them as it rotates. The yarn is withdrawn through a central opening in the disc. The disc has evenly spaced slots extending to its periphery and projection between the slots to retain and centralise the fibres inside the disc, thus enabling spinning to be carried out at high speeds. The invention provides a method ringless spinning with a reduced degree of "spraying of the fibres", producing a yarn with the desired linear density at increased rotor rotation speeds. The yarn spun according to this invention is cleaner than in commonly known ring spinning frames, due to the sepg. of foreign matter and the fibres as they pass through the central opening in the disc.

Title: Centrifuge degassing of viscous liqs. - e.g. silicone oil, preserves, with self acting product pump out control
Inventor: RUMPF HANS PROF DR ING
IPC: F04B43/06
Filed: 1975-06-03
Abstract: The specific. describes a process for degassing a viscous liq. using a centrifuge, in which the liq. to be degassed is applied as a film flowing on the inner surface of the centrifuge rotor. The film is sepd. into a bubble-depleted film on the surface of the rotor and a bubble rich film superimposed on the first film. The two films are sepd. from one another before leaving the centrifuge. The bubble-depleted fraction is accelerated into a liq. reservoir from which it is pumped by at least one membrane pump running round with the centrifuge motor to the rotor axis and centrally drawn off from the axis. The membrane pumps operate continuously without being controlled. When the feed rate to the centrifuge falls, the draw-off rate of bubble-depleted liq. is automatically reduced or stopped to prevent draw-off of bubble rich liq., without the need for a complex control system. No doctor blade is required to split the bubble-free fraction from the bubble rich fraction.
