Title: Single-lever water mixer for e.g. showers - has two ceramic discs with inlet and outlet holes with variable degrees of alignment
Inventor: RAETZ KARLHEINZ DIPL PHYS DR
IPC: F16K11/074
Filed: 1979-03-14
Abstract: The single-lever water mixer has a ceramic disc (1) with a hole (2) through which water leaves the mixer and several holes through which water enters the mixer. A second ceramic disc (6) with a blind hole (7) is arranged so that only one or two of the inlet holes lead to the outlet hole. Rotating the second disc w. r. t. the first presents a range of mixing ratios between any two adjacent inlet holes and therefor a range of outlet water temps. If there are three outlet holes they are connected to cold water (40 degrees C), warm water (>40 degrees C, 70 degrees C) and hot water (>70 degrees C).

Title: Storage device for kitchen utensil - has cable drum with spring loaded clamp for cable plug end, having roll with releasable lock
Inventor: VOIGT FRIEDER DR ING
IPC: B65H75/44
Filed: 1979-04-19
Abstract: The kitchen utensil, such as a liquidiser-mixer, is provided with a firmly attached electric cable (9). The entire assemble is fitted in a storage device (1), possibly wall mounted.

Title: Automatic coupling for draw bar - has sprung ratchet to hold top of coupling bolt and includes hand lever
Inventor: CRAMER GEORG
IPC: B60D1/02
Filed: 1979-06-20
Abstract: An automatic coupling for a drawbar has a vertical coupling bolt (4) whose upper end (15) lifts into a hollow extension (17) over the coupling jaw and is retained there by a ratchet end (9) of the hand lever. The nose of the bolt is angled and is engaged by inserting the eye of the drawbar. This trips the ratchet and allows the bolt to drop into the locking position. The coupling allows automatic coupling, with the towing unit being able to back onto the drawbar. If the lever is raised to its full extend the coupling bolt raises sufficiently to engage a spring loaded ratchet ball (18) in the side of the extension to hold the coupling open until the lever is depressed.

Patent DE-3002451-A1 (DE)
Title: Heat pump utilising heat from own circuit - has second heat exchanger to transfer heat to evaporator
Inventor: BAUER HEINER
IPC: F25B30/02
Filed: 1980-01-24
Abstract: Heat pumps usually draw heat from the surrounding atmosphere, or other relatively cold source. This sytem can lead to ice forming on the surface of the evaporator or even to the freezing of any water used in the heat pump circuit. This problem is overcome by using heat from the heat pump itself to heat the refrigerant used in the system. The compressor (3), draws in the refrigerant in its vapour phase from the evaporator (1) and delivers it to the heat exchanger (5) where heat is extracted to supply the central heating system (6). Some of the heat remaining in the refrigerant is then extracted by a second heat exchanger (10) through a heat transfer fluid which is pumped by the pump (22) through a third heat exchanger (14) which surrounds the evaporator.

This branch line is branched upstream from a return valve built into the connection line on the working cylinder. The branch line is connected to a connection line (50) linked directly to the pressure line of the control pressure pump (80) and switched on and off by a built-in magnetic valve.
Patent DE-3022003-A1 (DE)
Title: Toilet soap esp. for children contains capsule - esp. concealing toy or figure as incentive for child to use soap
IPC: C11D17/04
Filed: 1980-06-12
Abstract: A bar of high quality or toilet soap of an appropriate form contains inside it a two-part, hollow capsule. This capsule may be spherical and/or may correspond to the external shape of the piece of soap itself. Preferred materials for the capsule are soft, plastics or duroplastics. The capsule itself may be externally coated with a soap material harder than that of the remainder of the bar. The soap is intended esp. for children, the internal capsule being easily taken apart after the soap has been consumed; it may then reveal inside it an attractive figure or toy. Thus there is an incentive to the child to use the bar of soap in order to reach the figure contained within it, by contrast to the conventional idea where a bar of soap in the form of a figure rapidly loses that appearance as it is consumed.

Title: X=ray diagnostic appts. with area limiting - has adjustable image taking field, using shutter stripe, for division of field of stray radiator
Inventor: FINKENZELLER JOHANN
IPC: G21K1/02
Filed: 1980-09-16
Abstract: The X-ray diagnostic appts. has a scatter radiation raster (10), movable from a ready position into a picture taking one. It has also adjustable shutter plates (8,9), near the film, limiting the radiation field. Thus the shutter size is defined, ear the film, by the plate shapes. The radiation raster has, therefore, two parallel shutter strips. These strips serve for further sub-division of the beam field (6) on the raster side, facing the picture taking position. They define the smallest taking field, which can be adjusted in cooperation with the shutter plates, near the film. The space between the strips on the radiation raster may be filled up to their half width with radiation scattering strips.

Title: Connecting element for the flexible connection of construction elements in a manner which allows the transmission of spring forces
Inventor: PASCH ERHARD
IPC: B62B9/00
Filed: 1981-02-24
Abstract: The invention comprises a connecting element for the flexible connection of construction elements which allows the transmission of spring forces and is used, for example, in connecting the longitudinal spring and the scissor-type brace of a pram, but can also be used in other areas such as, for example, the incorporation of a vibrating screen into the oscillatory system. The connecting element consists of a sturdy force transmission part which is designed as a curved bar and of a protective part of flexible and corrosion-resistant material. Both parts are connected to one another in a positive-locking and exchangeable manner, so that the protective part hugs the inner side of the force transmission part. If the force transmission part is designed as a curved bar with a round cross-section, it is expedient to design the protective part as a strip-like element which, on the side facing the curved bar, has webs which flank the said bar.
