Title: Crankcase venting valve for IC engine - has flexible membrane in double conical body with outlet to engine induction manifold
Inventor: KERN HANS
IPC: F01M13/02
Filed: 1977-09-02
Abstract: The valve is formed from two conical sections with their wider ends together. The flanges on these ends grip a flexible rubber membrane (2) between them. One conical chamber (4) has a connection (6) to the crankcase. The other (5) has a connection (7) to atmosphere and contains a pipe (8) coming from the induction manifold. The membrane has a central opening (9) with a flanged part (10) inside it which fits over the end of the pipe (8). When the crankcase pressure exceeds atmospheric the membrane deflects to uncover the opening to the induction manifold and thus vents the crankcase gases into the engine the manifold.

Title: Recovery system for domestic waste water heat - has several evaporators and common condenser with low pressure distilled water
Inventor: ARCHER JOHN NEVILLE ING GRAD
IPC: F24D17/00
Filed: 1977-12-09
Abstract: The heat transfer system is used for heating water supply and heating systems in a building. The heat carrier circulates in a closed cycle between evaporation and condensing zone. The condensed carrier is returned as liquid to the evaporator. This system utilises waste heat in waste water in residential blocks with economy. The hot waste water flows through the evaporator and heat is transferred there to evaporate the heat carrying medium. Several such evaporator zones can be used and all are connected to a common condenser (6). The heat carrier is distilled water at a pressure of at least one hundred millibars. Alternatively, the distilled water is used at a pressure = thirty millibars.
Patent DE-2807647-A1 (DE)
Title: Power factor correction capacitor circuit for single phase - operates with independent supply for charge reversal of idle compensator
Inventor: SCHMID EBERHARD DIPL ING
IPC: H02J3/18
Filed: 1978-02-22
Abstract: In a single phase compensator for power factor correction the AC capacitor (3) remains in a charged state when the switch (5) connecting it to the network (2) is opened by the control system (6). When it is switched OFF the capacitor is in a standby state, but periodic reversal of the charge is necessary to preserve the properties of the dielectric. Reversal, at a fraction of supply frequency, is effected by connecting the capacitor alternately to a DC source of opposite polarity (8, 9) through a special switch (7). By this means the periodic reversal charge is not drawn from the network which therefore remains undisturbed.
Patent DE-2808920-A1 (DE)
Title: Water-soluble sizing removal - uses measured volume of water on fabric to improve size recovery rate
Inventor: DESCHLER OTTO
IPC: D06B3/12
Filed: 1978-03-02
Abstract: Water-soluble sizing from a woven fabric is extracted by treating the fabric with VA=F.A.B+D litres water per 1000 kg. of fabric, and then squeezing out. F is a value from 0.07-0.09, A the wt.% of the warps in the fabric, B the wt.% of the sizing on the warps, and D the residua fluid content in the fabric in litres per 1000 kg. of fabric after squeezing. The process uses exactly enough water to remove the water-soluble sizing so that it can be recovered for further use. The recovered fluid is pref. treated with methyl cellulose alone or with aluminium salts, to remove any impurities, and then filtered. The equipment needs a washing vat, a squeezing trough and a squeezing unit.
Patent DE-2811731-A1 (DE)
Title: Solar heat collector - with space between twin hemispherical or semi-cylindrical shells evacuated
Inventor: GOEPFERT WOLFGANG
IPC: F24S10/50
Filed: 1978-03-17
Abstract: Solar heat collector has a hemispherical or semicylindrical shape. The outer shell of the collector consists of two transparent layes an the space between them is evacuated. A heat carrier fluid is passed through the gap between this outer shell and an inner absorber shell which also consists of two layers, with the space between them evacuated. This results in a highly efficient lightweight design because the shells can be made of plastic material.

Title: Insect catching device - with glue coated bag inside ornamental open vessel contg. suction fan
Inventor: HOELTER HEINZ ING GRAD
IPC: A01M1/14
Filed: 1978-08-10
Abstract: A catching appliance for flies and other insects is disguised as a jar (for kitchen) or a flower vase or lamp (for lounges) in which a bag, coated with fly glue and a honey-aroma is hung from the rim. A suction fan at the bottom draws in air on the top together with the insects and discharges the air through holes in the bottom.

Title: Windscreen washer blade with integral washer - has with reciprocating valve element to spray leading edge of blade
Inventor: KIRBACH EMIL
IPC: B60S1/52
Filed: 1978-09-09
Abstract: The windscreen wiper blade is mounted under a hollow support bar (6) with a laterally sliding mounting. As the wiper drags across the windscreen it is displaced to the trailing side of the hollow support and closes off the water jet (8) on that side while exposing the water jet (7) on the leading edge. The washer performs a reciprocal action to cover the leading edge of the wiper blade so that an efficient washer/wipe action is obtained without obscuring vision.

Title: Fluid ballast system for floating platform - has horizontally divided compartments linked by diagonal cross ducts and pumps
Inventor: KOVALTSCHUK MICHAIL VLADIMIROV
IPC: B63B39/03
Filed: 1978-09-28
Abstract: The roll stabiliser for a floating platform has lateral tanks divided into upper and lower sections by horizontal walls (3). Pumps on each side pump fluid ballast from the bottom tank to the top while a controlled flow can be set up between the top tanks and the diagonal bottom tanks. Only one way simple pumps are required, with the remainder of the stabilising controlled by gravity fed flow valves. The flow valves allow large volumes of ballast to move without requiring large throughput pumps.

The insert then has a second bore formed by boring from the opposite side of the insert, so that the two bores are continuous, this second bore having the same dia. as the outer sheath of the optical fibre (4). The latter is then inserted in the second bore and glued in place, so that the stripped core (3) of the optical fibre projects into the first bore. Pref. the centre is milled in the end face of the brass insert via a pointed tool fitted in the centre of a cylindrical bore in a guide block with the same dia. as the fixing cylinder (1) which can be slid into it.

Title: Light duty multipole connector socket - has integral internal spring contact and outgoing terminal
Inventor: BUECHS HUBERT DIPL ING
IPC: H01R43/20
Filed: 1978-10-27
Abstract: The connector contacts are entered from the front side (1) of the socket housing moulding so that the extension (9) from the spring contact projects through the base of the moulding. These extensions are then deformed to provide location and terminal ends. The preassembly is placed on a work plate (16) and the spring contact ends held by a clamp.
