Title: Electrical safety lock for containers holding valuables - has electronic locking and releasing keys and detachable coding elements
Inventor: POSKE FRITZ
IPC: G07C9/00
Filed: 1977-04-21
Abstract: The electrical safety lock ensures that a door cannot be opened by an unauthorised person. This lock can be used for rooms or cabinets or containers for holding valuables, money or confidential documents. This arrangement is locked electromagnetically and the locking process is controlled by an electronic arrangement. For closing or opening, semiconductor elements are used in the manner of an electronic key. This semiconductor arrangement is withdrawn after completion of locking process. The security is improved by removing a coupling element with oscillating circuits or other coded electrical switching elements and bypass conduction path. The locking combination can be selected individually and freely by the user. Two electrical keys can be used, one for locking and the other for opening.

Title: Refrigerating element in form of drinking vessel - has cavity for drink cooled by ice as cooling element
Inventor: WEIGL GERHARD
IPC: A47G21/00
Filed: 1977-04-22
Abstract: The refrigerator element is used for cooling of drinks, esp. spirits. The cooling element utilises water frozen to ice as storage element for heat absorption. The drink is cooled directly after pouring from a bottle which is not itself cooled. The cooling element has a cavity into which the drink is poured on serving. This ensures that the served drink is cooled with direct contact with the cooling element, which can be designed as a drinking glass. The drinking vessel into which the drink is poured can have a hole by which it is connected to a drinking straw. This drinking vessel can be enclosed by holding arrangement which protects hand against cooling.

Title: Echo-sounder oscillator installation in GRP boat hull - uses spherical faced oscillator adaptor, fitting into mounting block bolted to hull
Inventor: HAHN JOACHIM ING GRAD
IPC: G10K11/00
Filed: 1977-07-04
Abstract: The scheme is used for installing an echo sounder oscillator inside a GRP boat hull.

Title: Instant picture camera shutter release - uses depress and release operation of shutter release lever and levers to control picture output feed
Inventor: ETTISCHER HELMUT
IPC: G03B17/52
Filed: 1977-07-09
Abstract: An instant picture camera has an electric motor to feed the frame out of the cassette and out of the camera. The sequencing of shutter release and motor drive is controlled by the shutter release button. The shutter release is operated against spring tension.

Patent DE-2740199-A1 (DE)
Inventor: LINSINGER ERNST
IPC: F16J13/24
Filed: 1977-09-07
Abstract: The device has a closure cap (10), which spans a tubular branch, and a bush (7) arranged in the tubular branch (3). Mounted movably in the bush (7) is a piston (19) which is designed to allow it to be brought up against the closure cap (10) under the influence of the pressure (P) prevailing in the vessel (B). In the open position of the device, a driver (11) projecting from the bush-side inner-surface section (12) of the closure cap (10) engages in an aperture (13) in the bush end wall (14). When the vessel (B) is under pressure, the piston (19) is pushed towards the bush end wall (14) and the driver (11) is pushed out of the aperture (13), thereby preventing unintentional opening of the pressurised vessel. <IMAGE>

Title: Continuous casting process - with solidification effected in the presence of electric current and magnetic field to agitate molten metal
Inventor: SASAKI KANTARO
IPC: B22D11/12
Filed: 1978-02-28
Abstract: In a continuous casting process where a molten metal is drawn through an open ended mould in the form of a continuous slab, a specific portion of the continuously moving slab which is passing through a second cooling station and still includes an unsolidified metal in the inner layer thereof, is subjected to a magnetic field which cooperates with an electric current conducted to the slab and produces agitation force on the fluid metal as it solidifies, thus avoiding centre porosity. The magnetic field comprises a series of alternately-directed loop flux regions which produce a number of counter flows along the width of the unsolidified metal band, thus assuring uniform compsn. across the width of the slab.

Title: Heat pump operated hot water producing plant - is heated by heat pump condenser at optimum point without regulation
Inventor: HAHN MANFRED
IPC: F24H4/04
Filed: 1978-04-10
Abstract: The hot water preparing plant has an insulated water boiler connected to a condenser of compressor operated heat pump. The condensation pressure in the circuit can be readily limited without intervention in the refrigerant circulation. The heat losses in the water boiler are kept equal to the heat transferred by the condenser at an optionally selected maximum pressure of the refrigerant.

Title: Abrasive disc contg. abrasive and binder - and embedded fibre reinforcement having high modulus of elasticity and length
Inventor: WAIZER WALTER DR
IPC: B24D3/34
Filed: 1978-07-05
Abstract: High strength reinforcing fibres, (I) having length >=10 mm and modulus of elasticity >=1 x 104 kp/mm2, are incorporated in abrasive discs contg. abrasive grains, resin-esp. thermosetting resin binder and filler. The fibre reinforcement may consist of mono-crystal whiskers and/or polycrystalline metal whiskers and/or B fibres, partic. synthetic, inorganic fibres. Fibre adhesion in binder matrix is improved by providing the fibres with a surface coating having a high chemical and/or physical affinity to binder, e.g. by oxidn. Thus, the fibres may be high-strength C fibres, oxidised on surface, or may consist of drawn metal wires, esp. of higher alloyed C steel coated with a primer. Working velocity can be increased without increasing vol. proportion of reinforcing material in abrasive disc.

IPC: F16F1/32
Filed: 1978-07-06
Abstract: The support for a dished spring comprises a bush (14) which has some resilience in radial direction whilst it is rigid in axial direction. The geometry, material and bearing support of the bush are selected to give a radial resilence such that through frictional contact alone it completely follows the radial deformation of the spring thus eliminating frictional wear. The bearing surfaces of the spring may be contoured, pref. forming shoulders (12), such that the spring is supported at a level where its radial deformation due to loads, equals or approximates zero.

Title: GFR plastics laminate ski runner or top prodn. - by precuring after rolling up with release film and covering film, then unrolling
Inventor: KUNTARA WILHELM DR
IPC: B29C70/00
Filed: 1978-07-19
Abstract: In the prodn. of GFR plastics laminate ski parts, glass fibre fabric impregnated with (epoxy or polyester) resin, after squeezing out excess resin, is rolled up with a release film (polypropylene or PTFE) and another plastics film (polyethylene or ABS) to be bonded to the glass fibre layer. The resin is precured, then the roll is unwound and the flat laminate, forming the runner or tope layer, is taken off. The laminate can be used directly for ski mfr. without further treatment. Pref. the impregnated fabric is rolled onto a spool with flange spacing corresp. to the width of the fabric or the ski part (which prevents resin being squeezed out at the edges). The glass fibre fabric may have selvages.

Title: Missile guidance system - using laser beams for scanning, correlating reflected rays and sequentially scanning terrain elements
Inventor: BORN GUNTHARD DR ING
IPC: F41G7/34
Filed: 1978-12-23
Abstract: The guidance system uses a series of laser beams (V, R, L) directed downwards in varying directions from the missile (300), with the reflected radiation correlated to obtain missile guidance signals. At least two laser rays(1, 2) within one of the beams (V) scan the same adjacent terrain elements(101, 102) one after the other, with the correlation obtained between the subsequent time modulations of each two such reflected rays(11, 12). The latter laser beam (V) is directed in front of the missile(300) with two additional beams (R, L) directed to either side of it, with the difference in the obtained correlation times for the latter two beams (R, L) used to provide the rotation of the missile about its vertical axis. The beams (V, R, L) may be modulated to allow the missile altitude to be determined by comparing the transmitted and reflected beams.
