Patent DE-2535625-A1 (DE)
Title: Large area pivoted flap valve - is operable by crank mechanism having over centre position when valve is closed
Inventor: ERICHSEN VOLKER VON ING GRAD
IPC: F16K31/52
Filed: 1975-08-09
Abstract: The flap valve for large flow areas comprises a rigid flap (3) engageable with a seat (6) at one side of a partition (2). A pivot (4) adjacent the seat connects the flap to the partition at its one side. At the other side the flap is connected by a connecting rod (12) to a crank (10) secured to an operating shaft (9). When the flap is closed the ends of the connecting rod are situated at opposite sides of the shaft slightly beyond the dea centre position to oppose opening of the flap by fluid pressure. The partition may have several openings each controlled by such a flap.

Title: Packing insert frame with cladding - has inner edge chamfered at corners to clear notch apexes (OE-15.8.75)
Inventor: HIRSCH HANS
IPC: B65D25/02
Filed: 1975-09-09
Abstract: The insert is particularly for use with jewellery, having V-shaped notches cut in the outer corners of the frame. The inner edge (2) of the frame is chamfered at the corners (3), and the apexes of the notches (4) are situated at the theoretical points of intersection of the inner edges. The frame can be stamped out from a sheet of material forming one or more inner edges and a centering mark in the process. Cladding material is then applied to one side, typically by gluing, to cover the sheet, and frame and cladding are finally stamped out together along the outer edge. The mark centres the sheet in relation to the second stamping tool.
Patent DE-2545398-A1 (DE)
Title: Wiring duct for switching cubicles - has slotted sides acting as springs and also forming wire exits
Inventor: BENDER GERD
IPC: H02G3/04
Filed: 1975-10-10
Abstract: A wiring duct made from synthetic material with a measure of elastic deformability, consists of a base (1) to which fingers (3) are attached whose upper ends (4) are bent inwards through more than 90 deg. to point downwards at a slight angle. The fingers are separated by vertical slits (2) which allow each finger to flex independently and also provide local exists for the wiring. The extreme ends of the fingers may be slightly enlarged to extend beyond the slit width to effectively close the top of the duct. Wires are entered by pressing through the opening at the top of the duct, the fingers deflecting readily due to the lever action. If a wire is inadvertently pulled to the top of the duct it tends however to move into the angle formed between the finger (3) and its angled end (4). The lever action is negligible and the duct does not spring open.
Patent DE-2549407-A1 (DE)
Title: Colouring stainless chromium steel articles - by electrolytic surface oxidn. stopped by superimposing direct current backlash voltage
Inventor: RUHSTORFER FRIEDRICH
IPC: C25D11/00
Filed: 1975-11-04
Abstract: The articles are coloured in an immersion bath, with heating, by forming a colour-yielding oxide surface layer, removing from bath and washing. Layer-formation in immersion bath is stopped by superimposing a D.C. backlash voltage on articles, as soon as desired colour effect is reached. Colour shade reached at moment of reversing polarity is fixed. Pref. after reversing polarity, articles are left some time, e.g. 2-5 min., in an immersion bath, before removing and cleaning. This treatment improves abrasion-resistance of coloured surface by consolidating the previously formed colour-coating. Backlash voltage can be superimposed by joining the -ve pole of a DC source to galvanic support.

Title: Temperature control network for domestic immersion heaters - uses temperature dependent resistor transducer and timed triac current control
Inventor: SCHENETIN NORBERT
IPC: G05D23/24
Filed: 1975-12-19
Abstract: The control network for domestic hot water immersion heaters, uses a temperature dependent resistance multi-vibrator timing circuit, and a triac current switch. The temperature transducer consists of a temperature expendent resistance (Rt) which is mounted in one arm of a bridge network (R3,R5,R5,R7) one element of which (R7) may be adjusted to change the set point temperature. The bridge output feeds an amplifier (N) which is linked to a monostable multi vibrator (MV) triggered at mains frequency, and these drive a triac (Tr) which controls the current to the immersion heater (hh). The circuit provides the heater with current for between one half and one mains cycle at mains frequency, depending on the difference between the set point and controlled temperature.

The can (K) has a chamfer (Fk) on the inside of its rim, mating with a chamfer (Fb) on the can base (B); can (K) is located in a lower die forming one electrode (E2). An upper electrode (El) has a projecting rim exerting pressure (P) on the rim of base (B) so two forces result, Ps and Ph. Ps is at 90 degrees to joints surfaces (Fk, Fb), providing good electric contact between the latter; force Ph is horizontal, pressing the base outwards against the can; and Ph = epsilon Pr, where Pr is the force provided by die (E2) holding the can wall. Several different types of chamfer may be used between can and lid. A reliable hermetic seal can be obtd. without using any flange.

Title: Sharpener for metal cutting saw - has grinding wheel with asymmetrical profile to reduce wear of wheel rear face
Inventor: POPP HARTMUT
IPC: B23D63/12
Filed: 1977-07-27
Abstract: The teeth of the metal cutting saw blade (1) are sharpened by a motor driven grinding wheel. As each tooth is ground the blade is moved (8) whilst the grinding wheel(6) is oscillated (7). The profile(4) is ground by the rear edge of the wheel whilst the radius (3) and flat edge (2) are ground by the front edge of the wheel (6). To reduce the wear on the rear edge of the wheel the radius of the rear edge is made several times greater than the radius of the front edge. This enables the grinding wheel to be used for longer periods between dressing.

IPC: H01L25/11
Filed: 1977-09-02
Abstract: The semiconductor valve cooler (2) has ribs (17) for a directed coolant flow, which are essentially arranged in the form of a star in cross-section. These coolers (2, 3) are used for semiconductor valve columns with disc-shape semiconductor valves (1). The ribs (17) of the cooler mainly extend in the longitudinal direction and are preferably constructed axially parallel or helically. Current and heat are transferred to the semiconductor (1) or respectively coolers (2, 3) via the two contact surfaces (21, 22) of the cooler which are planed parallel to one another. According to one use, one or a number of semiconductor valve columns are combined in an oil-filled tank to form a static converter, the individual columns being surrounded by an insulating jacket (23) which tightly encloses the ribs (17) on the outside, which jacket, together with the rib flanks, limits the directed coolant flows. <IMAGE>
