Title: Mechanical energy storage with crank drive - has energy storing rubber rings held in tubes driving inertia rotor
Inventor: GALLE EUGEN
IPC: F03G1/00
Filed: 1975-02-03
Abstract: The mechanical energy storage arrangement has a crank drive for displacing weights by human power, or by a wind or water wheel. The energy is stored in rubber rings in a tubular housing, these rings being firmly held for later release of energy. The energy is recovered by a rack or an endless sprocket chain. The loaded storage tubes can be fitted into a rotor driving device. This rotor can drive an electric generator. A liquid or solid medium may be poured into the rotor at the beginning of the rotation, until the kinetic energy is wholly spent. The system recovers about 95% of stored or imparted energy.

Title: Honeycomb extrusion esp thermoplastics produced through moving slits - in extruder nozzle to give meandering shape to extruded strips
Inventor: MORIKAWA AKIRA
IPC: B29C48/08
Filed: 1975-06-21
Abstract: An extrusion head for extruding honeycomb structures comprises a fixed mould having an opening equal in width and height to the overall cross-section of the intended extrusion, and a transversely sliding plate fitted like a shutter across this opening and itself furnished with horizontal and vertical slits; thus, as this plate is slid reciprocatingly from side to side horizontal bands are extruded through the horizontal slits and meandering vertical strips through the vertical slits. In the embodiment illustrated, the shutter is constituted of a number of separate horizontal bars or plates, each of which is shallower at the rear than at the front, and has vertical cuts to constitute vertical slits; the horizontal slits are formed by the distance gaps between these horizontal bars. The bars may be combined as a single unit, i.e. all driven together reciprocatingly as shown by the arrows, or they may be separate units driven in different movements. For the production of all types of mouldings having a very high area-vlume ratio, e.g. for regenerators, coolers, heat exchangers, catalyst supports, filters etc. The apparatus is intended primarily for extruding thermoplastics, but can also be used for ceramics. The resultant product is free from internal stresses.

Title: Surge diverter with non-linear resistor - has isolated air pockets to maintain constant element temperature
Inventor: OSTWALD HEINZ GEORG
IPC: H02H9/02
Filed: 1975-09-05
Abstract: The surge diverter comprises a stack of resistance elements (2, 2a, 3b, etc.) having a negative temperature coefficient. They are assembled between fins (3) on a central bolt (37) and clamped under pressure. The fins serve to dissipate heat and prevent a too rapid rise in temperature when the diverter is active. The construction is as in 2425814. To guard against the effects of fluctuating ambient temperature, and in particular against a large drop in temperature giving an unacceptably high resistance, the fins (3) are provided with a large diameter hole so that an air pocket (30, 31, etc) is formed between the discs which covers approximately 85% of the disc area. Where very low temperatures may be expected a heating element (38) may be installed in the bolt (37) bore and connected to a temperature control circuit.
Patent DE-2548600-A1 (DE)
Title: Helicopter detector for submarine - uses heat sensor and sonar on periscope to differentiate aircraft from surface ship
Inventor: FIBICH WOLFGANG DR ING
IPC: B63G8/39
Filed: 1975-10-30
Abstract: The periscope of the submarine is fitted with a scanning heat detector and a scanning sonar. The heat detector picks up all types of craft, while the sonar identifies surface vessels, which can be separated from the signals. The presence of only the heat signal signifies an aircraft. The helicopter type of aircraft is identified by electronic processing of the heat signal, to pick out the cyclic beat of the rotors, on the thermal pattern. Both sonar and thermal patterns can be displayed on the same CRT for rapid identification of possible submarine hunting helicoptors.

Patent DE-2559493-A1 (DE)
Title: Bobbin creel yarn monitor - has independently mounted yarn eyelets with drop needles to give a universal unit
Inventor: THEIHSEN HANS
IPC: D03D51/34
Filed: 1975-10-04
Abstract: An appts. is claimed to monitor yarns in a bobbin creel assembly, to register yarn breakage, using a number of eyelets in a housing through which the yarns pass, each yarn supporting a drop needle in the eyelet, which descends if the yar is broken to make a contact to generate a stop signal. The fixed eyelets are mounted on a carrier bar independently of the yarn monitor housing sections. The monitor housing sections are keyed to the carrier bar and held in place by clamps bearing against loading points on the outer surface of the carrier bar. The design gives a universal mounting for all types of bobbin creel, with simple return to normal working after a yarn breakage, so that the eyelets can be used without the monitor housing used as a yarn guide, if necessary.

Title: Direct electrodeposition of chromium onto nickel - from a chromium electrolyte using a direct current with superimposed pulses
IPC: C25D3/04
Filed: 1976-02-06
Abstract: The electrodeposition of a hard Cr layer directly onto an S-contg. Ni substrate comprises operating the Cr electrolyte, which may be of known type, with a direct current with superimposed pulses.

Title: Rail guided sliding sectioned shower cubicle partition - has narrow floor rail and side rails with edges aligned with head rail
Inventor: SUDMANN JUERGEN
IPC: E06B3/46
Filed: 1976-10-21
Abstract: The shower (or both-tub partition) comprises a sliding door made up from horizontally movable elements hanging from a headrail and led in a floor rail. Both rails are joined to a peripheral frame by vertical siderails, the elements being gathered close together in the frame in a staggered alignment or one behind the other. Side rails (3) and floor rail (2), at least, are narrower in profile than the thickness of the bundle of elements, and the outwards facing surfaces of all the rails are in alignment with each other. The headrail (1) may be wider than the other rails, with transitional pieces fitted between itself and the side rails at the frame corner joints. This makes a narrower frame feasible, with no dirt-trap in the form of a cubicle floor overhand, or danger of floor rail being loosened.

Patent DE-2714919-A1 (DE)
Inventor: FEIND RICHARD
IPC: B65D47/00
Filed: 1977-04-02
Abstract: The container (1) consists of a bottom part (2) and a lid part (3) which can be removed therefrom. In order that the container can be filled only after the lid part has been fitted onto the bottom part, which simplifies the filling and closing operation, one or more flexible closure flaps (5) formed by slots (4) are provided in the lid part. To fill the container, in a simple manner a filling mandrel can be introduced into the container between the flexible closure flaps. When the filling mandrel is retracted again after filling, the filling opening closes by itself in that the elastic closure flaps automatically return to their closure position. <IMAGE>
