Title: Continuous fabric process equipment - has parallel dividing walls in the vessel to give low fabric tension
IPC: D06B3/16
Filed: 1974-12-14
Abstract: Appts. for carrying out a continuous wet treatment process for the shrinking, relaxing or bulking of continuous fabric material such as a texturised woven or knitted polyester in which the vessel for the treatment fluid is divided by a number of vertical walls spaced from the outer wall. The process zone and the fluid return zone are incorporated within the vessel so that the fluid can flow in a loop above and below the dividing walls. The design allows the material to be passed through for thorough impregnation by the treatment fluid, while the fabric is subjected to minimum tension.

Title: Single track roller skate - or roller skating boots having only one wheel at back and at front
Inventor: KIRMSE MANFRED
IPC: A63C17/06
Filed: 1975-02-20
Abstract: The one track roller skate or roller skating boot has just one wheel at the front and one at the back with the wheels situated in forked holders on knock out spindles. The shoe is particularly useful for summer training of ice skating as it has exactly the same running qualities as if on ice skates and it is very good for practicing ice hockey or racing on ice with fast starting acceleration by pushing off against the side of the skate. It is very light weight due to its construction and use of just one wheel back and front rather than two.
Patent DE-2510984-A1 (DE)
Title: Diagnostic X-ray equipment - provides warning of thermal overloading by taking energy to previous exposure into account
Inventor: KLAUMUENZER HARTWIG ING GRAD
IPC: H05G1/54
Filed: 1975-03-13
Abstract: The diagnostic X-ray equipment has an alarm to warn of thermal overloading of the X-ray tube during a subsequent exposure by taking into account the energy involved in a previous exposure. The temperatures of the anode plate and the X-ray tube's housing are coded into signals and stored for use during the next exposure to give the maximum permissible loading. These stored temperatures are incorporated into the setting for the next exposure, and the result of a comparison is used to trigger an alarm if the permissible loading is likely to be exceeded. The signals characterising the two temperatures are stored by capacitors.
Patent DE-2512015-A1 (DE)
Title: Mixing tap for hot and cold water - has metering chamber with sliding, rotating piston
Inventor: KAUT GUENTER
IPC: F16K11/18
Filed: 1975-03-19
Abstract: The hot and cold water mixing tap (1) receives cold water into its metering unit whilst the hot water flows straight into the mixing chamber (23). The cold water enters the metering chamber through the axial inlet port (16) which can be shut off by the central piston (5) that is attached to the valve operating handle (6). When this adjusting handle (6) is operated, the piston (5) is retracted and also rotated at the same time. This allows the cold water to flow through a tapered radial slot (46) and a hole in the cylinder bush to the mixing chamber (23). The angular position of the adjuster handle (6) is thus an indication of the mixing ratio.

Pref. the polar solvent has a dielectric constant at 20 degrees C of 6-200 esp. 7-75 and is pref. a cyclic or branched 1-6C alkyl sulphone or cyclic sulphone of formula:- (where n is 3-7) or a lactam of formula:- (where m is 3-8 and R is 1-6C alkyl), or aketone of formula:- R1-C(O)-R2 (where R1 and R2 are cyclo or branched 1-6C alkyl, or through -(CH2)0- where o is 4,5 or 6, are connected to a ring, opt, substd. by 1-3C alkyl). Process can also be discontinuous. Pure isomers are obtd. which can be reduced to corresponding amino cpds. which are intermediates for dyestuffs and polyurethanes.

Title: Fluidised bed leaching of polydispersed zinc ore concentrate - fed at different heights into spent acid electrolyte to aid leaching
Inventor: BUROVOJ ISAAK A
IPC: C22B3/04
Filed: 1975-07-08
Abstract: A process for the leaching of polydispersed ore concentrates by creating a fluidised bed of solid concentrate particles in a rising current of a liq. reagent, followed by the continuous feeding of the concentrate into the bed is described. The novelty is that the concentrate is fed into the bed at different heights. In leaching roasted Zn concentrates, feeding into the bed pref. occurs at two different heights, where 40-80 wt % of the concentrate is fed into an upper zone which is located at 0.5-0.8 times the total bed height, the remaining concentrate being fed into the bottom of the bed at the same level as the inlet for the liq. reagent. The process is used when leaching Zn-, Cu-, or other concentrates, esp. using spent acid electrolyte as the liq. The middle sized and coarse particles collect between the two inlet zones, empirical tests showing that these particles are exposed to a higher acid concn., i.e. before the acid dissolves Zn in the fine particles. The result is the improved extn. of e.g. Zn.

IPC: B60R22/405
Filed: 1975-08-01
Abstract: The inertia safety belt winder comprises a spring-loaded winder shaft on which is rotatably mounted an inertia locking plate (7). During jerky acceleration of the winder shaft, the locking plate moves in the axial direction of the winder shaft into a locking position from a release position in which its locking elements are disengaged from counter-locking elements on the housing, by axial oblique cam and counter-cam surfaces (14a, 15a) on the locking plate and winder shaft. In the winder shaft is at least one angled recess (15), and on the locking plate is at least one hooked projection (14) which when assembled is inserted in the recess against the action of a release spring, to form a bayonet-type connection. In the rotational phase of bayonet closure movement, the cam surface which is on the hooked projection abuts against the counter-cam surface in the recess.

Title: Stationary refrigerator compressor lubricant temp. control - has immersed pump circulating lubricant in a closed cycle
Inventor: TAUSCHECK WOLFGANG DIPL ING
IPC: F25B31/00
Filed: 1975-10-31
Abstract: Compressor lubricant control ensures to keep this slightly above ambient temperature, to avoid the coolant to condense in the oil and reduce lubricating efficiency. A circulating pump may be fitted in the engine sump or externally connected. When using a multigrade oil, the circulation is induced by a 0.25 - 1 kw pump, found efficient to heat 10-80 litres of oil by 2-5 deg.C. By using this arrangement no other heating form is required. Loss of oil from the circulation does not lead to overheating, which may occur when using an electric heater, and monitoring equipment is not required.

Title: Pneumatic damper for car seat - with separate piston for independent height adjustment by tapping some of damper compressed gas
Inventor: WINGEN WILHELM
IPC: B60N2/54
Filed: 1975-11-27
Abstract: The seat shell is supported on a plinth, or support column by a special pneumatic damper filled with a compressed gas. The damper is linked to the support (14) by a coil spring around the damper. One end of the damper has a piston with a setting control to alter the damping w.r.t. the seat loading. The adjustment is possible with the driver sitting on the seat. The other end of the damper is linked to its support by a second piston whose control valve is operated by a control shaft linked to a cam lever. This alters the effective height of the damper, by tapping off some of the compressed gas and passing it to the other side of the piston. The height control is thus independent of the seat loading setting.

Filed: 1976-01-09
Abstract: During the production of a pipeline, pipes (21, 22) are connected to one another which have a cylindrical centre section (21a, 22a) to which a conical expansion (21b) and a short cylindrical intermediate section (21c) are connected on one side. The internal diameter of the latter is approximately equal to the external diameter of the centre section (21a, 22a) and of the other end section (22b). The cylindrical intermediate section (21c) is followed by a further conical section (21e) and a further cylindrical section (21f), which forms one end of the pipe (21). When two pipes (21, 22) are being connected, a layer of adhesive material (23) is deposited onto the outer surface of the thinner end section (22b) of the one pipe, and the thinner end section (22b) of the one pipe is inserted into the thicker end section (21d) of the other pipe (21) until it rests against the inner conical expansion (21b). In this case, the adhesive material (23) on the outer conical expansion is stripped off so that it fills the intermediate space between the inserted pipe end section (22b) and the outermost cylindrical section (21f) of the other pipe (21) and closes it in a sealed manner. <IMAGE>
