Title: Ceiling and retainer suspension device - has flattened wedges with cross stem near helical spring allowing relative movement between retainer and socket
Inventor: BRAUCKMANN OTTO DIPL KFM
IPC: E04B9/18
Filed: 1977-03-22
Abstract: The device for suspending ceilings and fixing retainer elements in ceilings or walls comprises a retainer element with a wedge-shaped end section matching a slotted socket. A helical spring effects relative movement between the retainer and socket. The wedge-shaped end section of the retainer element (1) is formed onto the retainer dia. on two diametrically opposing sides (1c) in a flattened form. The socket (2) has lengthways slits running over its whole length. In the retainer's insertion direction it has a stem (2b) cut in on each of the parts formed by slitting. The stem pieces are connected at the end by cross stem (2c), and the helical spring (3) is mounted between this cross stem and the end of the retainer element.

Title: Dosing mechanism for supplying powdered additives to dishwashers etc. - includes program-controlled screw conveyor feeding in powder from supply pack
Inventor: HUBER HEINRICH
IPC: D06F39/02
Filed: 1977-04-06
Abstract: The dosing mechanism for supplying controlled amounts of powdered additives to the water in dishwasher, etc. includes a screw conveyor which is actuated by a programme control system and is used to feed the powdered additive in measured amounts from a supply container to the interior of the machine. The supply container contains enough additive for several doses and the amount supplied is determined by the running time of the screw conveyor and thus does not depend on manual control. The screw conveyor can be driven by an electric motor or by a flexible shaft which can be coupled if required electromagnetically to the already existing motor of the machine. The supply container which can comprise a replaceable packet of additive which can be set down on the housing of the screw conveyor and can thus be easily replaced when empty. The housing can contain a control gate to show the level of the contents.

Title: Angled double tenon connector - fits between tubular members of table frame uniting two square section table top supports and forming leg section seat
Inventor: SVENSSON ALGOT INGVAR
IPC: F16B12/50
Filed: 1977-05-27
Abstract: The angled double tenon (13) connector is for joining the tubular members (11, 12) of a table support frame. Two square hollow section members (11) of a subtable top (10) ring frame are joined to a tubular leg (12) at a table corner. The connector is of approx. 'L' shape with each of the legs (13) entering the end of a conjunctive ring frame member (11). The external angle is contoured (30) to form a concave seat for the leg section (12). In plan the tenons (13) subtend the angle required between the ring frame members (11), and a fillet (F) in the internal angle affects node enlargement to accommodate the leg seat (30). The fillet (F) is normal to the bisectrice of the inter-tenon angle, and the ring frame members are chamfer cut to a but (31) the leg section on the external elevation. The radius of the leg seat (30) may be reduced relative to that of the leg (12) which is fixed by a diametric bolt (14).

Title: Water carbonate hardness and salt content adjustment - by treating with a cation exchanger, removing carbon di:oxide with air and mixing with a reaction prod. of lime water and carbonated water
Inventor: EUMANN HANNS-HEINZ
IPC: B01J39/04
Filed: 1977-07-30
Abstract: The original water is led over >=1 acid cation exchangers and the stream is then split into two parts. One part is led through a trickle column in counterflow with a constant volume of air, which gives complete removal of all the free CO2 present. The other partial stream, which is acid and contains at least CO2, is led to a vessel (I) together with satd. lime water of a constant concn. The resulting carbonate soln. is added in the required amt. to the effluent from the trickle column. The vessel (I) is constructed in the form of a funnel whose rim is sealed to the inner wall of the trickle column. A vat is situated centrally beneath the funnel, having a larger dia. than the dia. of the funnel outlet. The leads from the lime water saturation unit and the cation exchanger feed in just above the funnel. (I) is made in the form of a funnel to overcome problems of blocking of the tubes, which were encountered in previous designs.

Title: Automatic cut=off valve for piping carrying radioactive gas - has pendulum flap responding to excess gas velocity, for use in nuclear reactor circuits
Inventor: RISS JUERGEN
IPC: G21D1/02
Filed: 1977-09-01
Abstract: The cut-off valve includes a freely suspended pendulum flap which leaves the inlet and outlet open within a hollow cylinder, without causing an obstruction. An excessive gas glow rate, caused by a fractured output pipe, causes the flap to swing against the outlet seat, where it is held by the excess (> atmospheric) pressure. The valve has a simple design; functions reliably after long operational periods and is easily returned to its initial position after a response.

Title: Pressed sheet metal aerosol cap - has hole in end surface produced by pressing in line of weakness whilst supported on mandrel
Inventor: DIEMI WERNER
IPC: B21D51/44
Filed: 1978-04-18
Abstract: The end cap (1) of an aerosol container is pressed from sheet metal and the partly finished workpiece has a flat end surface (4). The end surface is removed by first making a circular groove of V shaped cross-section around the rounded edge. This is done by using a tool (5) with a sharp edged circular hole whilst the cap is supported on a mandrel (2). When the groove has been formed, the flat surface is removed with a punch which is pressed downwards whilst the cap is supported on a hollow mandrel. This method enables the caps to be made from relatively brittle steel.

Patent DE-2821917-A1 (DE)
Inventor: SMETZ REINHARD
IPC: F16G17/00
Filed: 1978-05-18
Abstract: In the case of the hook, which can be used especially as a cord hook for choker chains and jerking chains in forestry, the free end of a curved section (2) of the hook is bent like a sickle so far towards the part (4) of the hook opposite it that, when the headpiece (1) is aligned vertically, the hook tip (5) lies on a vertical straight line which runs through the headpiece (1) of the hook. The shape of the hook on the one hand makes it easier to insert a length of chain and on the other hand makes it harder for said length of chain to become detached on its own. <IMAGE>

Title: Noise suppression in signal transmissions - has delay stage to suppress noise in signals received by vehicle from fixed location station
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: G08C25/00
Filed: 1978-05-25
Abstract: The transmission of signals between a fixed location station and a moving vehicle includes a reception facility to suppress noise. The incoming signals (4) are filtered (9) and are fed to a receiver for frequency modulated signals (10), consisting of a signal channel (101) and monitoring channel (105). Only when a specific signal amplitude is met to trigger a Schmitt trigger stage (107) is a relay operated (108) to allow the information through. The identification stage processes the signals over trigger stages (112, 113) and a delay stage (111). The generated signals together with the delayed mounting signal (117) are AND gate combined to ensure that short duration noise is eliminated.
