Patent DE-2619465-A1 (DE)
Inventor: REUTER FRITZ
IPC: F16K11/085
Filed: 1976-05-03
Abstract: In order to achieve the greatest degree of operational reliability with intensive mixing of the two liquid streams, the mixer unit has the following simple construction: a control body (6) is located in a cylindrical bore (5) of the housing (1). One metering slot (11) is connected to one feed channel (2) and the other slot (12) is connected to the other feed channel (3). The two slots are offset with respect to each other and communicate with an inner mixing chamber of the control body, said chamber being in connection with the discharge opening (4, 10). By rotating the control body (6) on the actuating shaft (7), the mixing ratio can be adjusted. <IMAGE>

Title: Multiple drive gear collective oil supply - has one of several oil pumps at full pressure, remainder circulates oil without pressure
Inventor: GROS HERMANN DIPL ING
IPC: F16N29/02
Filed: 1976-08-19
Abstract: Oil supply installation for a collective gear for several drive units works with an arrangement whereby there is a quantity of gear input shafts corresponding to the number of drive units. The input shafts may be connected at will to the collective gear, from which an oil pump for lubrication cooling or control is driven. When several drive units are operating simultaneously, and therefore several oil pumps (11) are being driven, only one of the oil pumps is working at full operational pressure. Via change over devices (17) controlled from this operating pressure, the other oil pumps are changed to pressure-less oil circulation.

Title: Hip prosthesis with cup-shaped ball socket - with self-tapping thread interrupted by upwards tapering free grooves
Inventor: BIRNER JUERGEN
IPC: A61F2/46
Filed: 1976-10-04
Abstract: Hip joint internal prosthesis comprises a ball cup-shaped joint socket to be implanted in the acetabulum (3).

Patent DE-2724704-A1 (DE)
Inventor: MAYER HERBERT DIPL PHYS
IPC: B23Q11/00
Filed: 1977-06-01
Abstract: The apparatus has a movable mounting device (8), for example an indexing plate, which takes the particles in intermittent feed one after the other to the treatment stations (9) provided, a correcting operation being allocated to at least one treatment operation if its sequence is found to be faulty. In order to prevent the correcting operation from stopping the apparatus for a full working cycle each time, the correcting operation or at least one of the correcting operations provided is started directly after the fault triggering it is found, and the combined further movement of the particles by means of the mounting device after the sequence of the other treatment operations is delayed only up to the end of the correcting operation.   <IMAGE>

Title: Multiple headed street light fitting - has arms formed from sleeves locked together by internal clamps with securing screws
Inventor: HESSE KURT
IPC: F21S8/08
Filed: 1977-06-08
Abstract: The decorative street light fitting resembling a tree or plant, has a main column representing the trunk, and a number of side arms in the manner of branches, each carrying a bulb holder inside a globe. The trunk and branches are all built up from tubular sections (5) secured at each join by locking screws (9) and internal clamps (10). Each clamp consists of a body with claws (10a) projecting from its ends which lock over the tapered faces of a boss (12) inside the tubular section, at the joint. The inside faces of the claws are less steeply sloping than the outside faces of the boss to ensure a locking action, when the radial screw is tightened up inside the clamp body. Inside the tubular section, radially at 90 deg. to the clamps are flats, acting as locating faces.
Patent DE-2729238-A1 (DE)
Title: Arc welding railway rails or profiles - using mould cheek with refractory insert to cover butt joint
Inventor: KRATZ JOSEF
IPC: E01B11/40
Filed: 1977-06-29
Abstract: The welding process uses rod or wire electrodes, and the mould cheek covers the butt joint of the two parts being welded together. The cheek is made of metal, and has a surface (a) parallel with the facing the two workpieces or rails; in surface (a) is a groove (b) contg. a refractory insert (c). The cheek is pref. made of copper, and the insert is pref. made of ceramic. Groove (b) pref. contains a peg for locating the insert (c), which can easily be removed and replaced. The insert (c) is pref. located in the middle of the cheek and also contains a grovoe (c1). When the cheek is made only of copper, arc welding may melt some of the copper which can then form an undesirable impurity in the weld. Conversely, if the cheek is made only of ceramic it has low shock resistance and is easily broken. The invention overcomes these disadvantages.

Title: Treatment of rinse water from aluminium chromating plant - using cation and anion exchangers
IPC: B01J39/04
Filed: 1977-12-30
Abstract: Purification and recycling of waste water from an aluminium chromating plant comprises passing the effluent from the rinsing bath through a 1st cation-exchanger bed and then through an anion-exchanger bed, and then returning it to the rinsing tank. During regeneration of the anion exchanger, the regeneration effluent is passed through a 2nd cation-exchanger bed to a collecting vessel, from which it is passed to the chromating bath. The only effluents requiring disposal are those produced during regeneration of the 1st and 2nd cation exchangers; these contain no Cr or CN and can be subjected to conventional waste-water treatment.

Title: Fitting for vehicle roof-mounted warning light - has suction pad with adjustable strap extending to side gutter to be held by clamp
Inventor: BRANDT ODWART
IPC: B60Q1/26
Filed: 1978-02-17
Abstract: The roof mounted warning light (1) for a vehicle is located on the roof by a rubber suction pad (9) and is stabilised in this setting by an adjustable strap (7) extending to a side clamp (6) on the side gutter. The strap incorporates the supply leads to the lamp. No permanent fitting is required on the roof so that a plain vehicle is rapidly converted for emergency use. The gutter clamp is fitted with a simple snap action, and without tools. The strap prevents the lamp from shifting on the roof.
Patent DE-2808327-A1 (DE)
Title: Buckle stabilised, externally reinforced bend moment girder - has permanent multi-function formwork and hand-setting interior filling
Inventor: BORSDORF HEINZ DIPL ING
IPC: E04C3/29
Filed: 1978-02-27
Abstract: The flexure girder incorporates buckle-resistant stabilised external surface reinforcements. Use is made of formwork units retained as a permanent element in the bend structure. The configuration of these determines the cross-sectional shape of the element. The interior space is filled with material which subsequently sets hard, with at least pressure-resistant and adhesive rigidity qualities. This takes over the role of buckle stabilisation of the external sheating and effects bonding outside the support areas without involving additional loop shackles. This enables high-quality girders to be produced by simple means, with external sheating performing multiple functions.
