Title: Boring machine tool with rotated work - has fixed tool moved to counteract cutting forces by automatic drive
Inventor: HORCHER WILLI
IPC: B23B31/08
Filed: 1976-11-12
Abstract: The method is for the central run-free machining of a workpiece placed in a rotating holder and involves the use broaching or drilling tools with at least two virtually symmetrical cutting surfaces. The clamping chuck (F) for the otherwise motionless tool, aligned with the rotary axis (A) of the workpiece holder (S), is displaced in an upright rotary movement permanently. The rotary movement is produced by an intermediary piece (Z) fitted between the tool chuck (F) and the chuck holder (R). The rotary movement originates from an automatic drive unit (T), which is adjustable and alterable as to direction of drive.

Title: Multiple loop cooling system for gas-cooled reactors - has individual primary loop flap valves with diametrically-opposed flaps protected by heat shield
Inventor: BARCHEWITZ EKKEHARD DIPL ING
IPC: G21C9/00
Filed: 1976-12-21
Abstract: The gas-cooled high temp. reactor with multiple loop cooling system is designed so that in the event of failure of a coaxial gas duct, selective closing off of primary loops is possible so that primary loop components may be serviced. In the vicinity of each horizontal opening in the circular chamber formed between the graphite reflector and the concrete, is positioned a hinged flap-valve operated from outside the concrete vessel. When closed, the valve seals off the side duct from the circular chamber. Each valve comprises diametrically-opposed flaps attached to a horizontal spindle and protected by a heat shield on the high-temp. gas inlet side.

Title: Moving ship hull cleaning process - uses half enclosed rotary brush which is rotated by movement of water
Inventor: BLUDAU JOSEF
IPC: B63B59/08
Filed: 1976-12-24
Abstract: A Roller-shaped wire brush is half enclosed in a housing in which it is free to rotate. When lowered over the side of a moving ship, the brush is set in rotation by the movement of the water. Being suspended in contact with the side or bottom of the ship, the rotating brush cleans the surface of the hull, removing barnacles and other marine growth. The brush is moved from time to time. The method facilitates cleaning during a voyage, not possible by other means.
Patent DE-2704999-A1 (DE)
Title: Strip steel knife producing system - has central groove formed in strip for guidance through machining and heat treatment zones
Inventor: SCHAEFER KARL A R
IPC: B23P15/28
Filed: 1977-02-07
Abstract: The strip-steel knife, producing system is partic. for knives used to form flat chips for chipboard etc. A narrow steel strip is passed continuously through a grinding zone where both edges are sharpened, after which these are set as necessary in a shaping zone by the formation of corrugations or the bending out of slotted protrusions, and then hardened and tempered in a heat-treatment zone. The strip is then parted off to the desired length. The strip (1) is provided with a central key or groove (5), by which it is guided through the grinding and subsequent processing zones. The groove is formed by milling or alternatively cold-rolled and then ground to finished size.
Patent DE-2707884-A1 (DE)
Title: Ash tray with cigarette ash removal flaps - has counterweighted bent flaps under lid, to remove ash as cigarette is withdrawn
Inventor: CERVINI LUIGI
IPC: A24F19/14
Filed: 1977-02-24
Abstract: The ashtray for use in a vehicle has an opening in the cover (3), for insertion of the glowing end of the cigarette (4) with two flaps (1) immediately below, which swing back to allow the end to pass through, and which remove the glowing ash as the cigarette is withdrawn. This action is assisted by counterweights (2) or springs on the flaps. Each flap can be L-shaped, with a hinge pin (6) at the bend point, to pass through holes at the end of a bridging piece (7) on the underside of the cover. Thus the flap can be made entirely of strip, with one end bent over to form a counterweight. A hollow rivet (8) can be fitted at the opening in the cover.
Patent DE-2712797-A1 (DE)
Title: Cavitation detector for liquid sodium reactor coolant - which measures phase-displaced component of flow speed or temp. signal
Inventor: NAKAMOTO KOICHIRO
IPC: G01N27/72
Filed: 1977-03-23
Abstract: A cavitation detection device comprises an excitation coil supplied with an Ac signl and two detector coils mounted adjacent to the excitation coil. The assembly is incorporated in a conducting flowing liq., e.g. liq. sodium, and is connected to a circuit for supplying a flow speed signal (e1-e2) and/or a temp. signal (e1+e2) (where e1 and e2 are the output signals of the two detector coils). A cavitation signal is produced by synchronous rectification of the flow speed signal or the temp. signal by means of a signal phase-displaced by 90 degrees with respect to this originating signal.
Patent DE-2719854-A1 (DE)
Title: Ball valve seating ring - has reinforcing ring around outside and is approximately semicircular in cross section
Inventor: GLIHA JOSIP DIPL ING
IPC: F16K5/06
Filed: 1977-05-04
Abstract: The ball valve with a plug rotated between the open and shut positions, has elastic seals between plug and housing and concentric to inlet or outlet. The seal is a ring (29) of roughly semicircular cross-section (30) with a cylindrical external wall (31). For roughly half its length which ends in a curved portion (47) it is retained in a cylindrical recess at the mouth of the discharge outlet. The roughly semi-cir ular face (35) of the ring is towards the centre line, and has between the housing and the plug a series of straight wall sections at obtuse angles to each other and subjected to the pressure in the flow direction. The part towards the plug has curved portions (43, 45) pressing gently against the plug surface and joining onto the cylindrical wall (31) of the ring, which is only subjected to pressure in the reverse direction. A thin supporting sleeve (49) is fitted in the cylindrical wall.
Patent DE-2724374-A1 (DE)
Title: Kitchen extractor hood for recirculating or removing waste air - has one double-section waste pipe for attachment to relevant exhaust outlets
Inventor: HOMEIER MAX
IPC: F24C15/20
Filed: 1977-05-28
Abstract: The exhaust air pipe (1) for the kitchen extractor hood comprises two sections (2, 3). One (2) has a full size air flow cross section whilst the other (3) has a substantially smaller air flow cross section. The two air currents from the two sections (2, 3) are combined outside the waste air box inside the first section. The first pipe (1) preferably has a full width outlet which can be connected to either the recirculating or exhaust opening (16, 17) of the waste air box (15) and a narrower diversion channel (3) which can be connected up to either the exhaust or recirculating opening (16, 17) of the box accordingly. This means that the same waste air pipe can be used for either recirculating or removing the air as required. The overall efficiency is improved since the increased air speed of the additional air flow through the diversion channel allows a lower speed fan and a smaller motor to be used.
Patent DE-2731699-A1 (DE)
Title: Clamp for holding workpieces during anodising - made of a modified polyphenylene oxide with high resistance to electrolytic corrosion
IPC: C25D17/06
Filed: 1977-07-13
Abstract: Clamp, for holding workpieces which are to be anodised against a rail in an anodising plant, consists of a curved yoke fitted at one end with a thrust pad and a threaded hole at the other end. A bolt screws into the threaded hole, and the two parts are made of a modified polyphenylene oxide resistant to electrolytic corrosion. The thrust pad forming part of the yoke is pref. shaped so that it will hold the clamp onto a support, esp. a mobile rail, when the clamp is not in use. The thrust pad thus has a T-shaped cross-section and is located either at the end or the middle of the yoke, so it holds the clamp in a mating T-groove in the rail. The clamping bolt is pref. provided with a two-start thread. The modified polyphenylene oxide has a corrosion resistance three times greater than a conventional plastic filled with a high content of china clay.
