Title: Terminal bushing for power cables - with synthetic insulation and wire earth contact to base of insulator
Inventor: HOLLAND KARLHEINZ ING GRAD
IPC: H02G15/068
Filed: 1977-10-13
Abstract: The insulator (1) is typically of synthetic material and contains a grading screen (2) of insulation loaded with conducting material. This screen makes intimate contact with the cable inner screen (10) and the outer wire screening (11).

Title: Seismic exploration method with enhanced survey results - has sensor array for sensing response of seismic horizons to emitted seismic waves
Inventor: TANER M TURHAN
IPC: G01V1/00
Filed: 1977-11-30
Abstract: The method of seismic exploration includes sensing the response of the seismic horizons to emitted seismic waves, by using a sensor array of aperture of a number of seismic sensors. The sensor array or aperture is larger than the dia. of a circular region, termed the Fresnel zone for the deepest seismic horizon of interest in which all ray paths for seismic waves at a highest frequency of interest differ in phase by less than one-half wavelength. With an aperture of this size, the responses of seismic horizons sensed by the sensors differ from each other in phase by less than one-half wavelength. Individual sensors in the array are spaced from the next adjacent sensors by less than or equal to one-quarter wavelength of horizontally travelling seismic noise waves at the highest noise frequency of interest.

Title: Magnetic damping brake for electrical instruments - uses two perpendicular permanent magnets producing field parallel to rotating element
Inventor: KONASCHINSKY JURY ALEKSANDROVI
IPC: G01R1/14
Filed: 1978-10-25
Abstract: A magnetic damping brake for electrical measurement devices uses two permanent magnets arranged so as to require minimum steel and to be smaller than in conventional arrangements.

Title: Magazine loading mechanism for cigarettes - has cam acting on links to container holders from rotary support
Inventor: BARDENHAGEN DIETRICH
IPC: A24C5/352
Filed: 1978-10-30
Abstract: The mechanism loads a magazine with cigarettes and similarly-shaped tobacco articles from containers delivered in succession, having two or more holders for the containers on a rotary support above the magazine. These transfer the full containers from a first station to the magazine, and empty ones from the latter to a second one. The holders (1, 2) pivot by means of links (7, 11) on opposite sides of the support (6). An intermittently-driven control disc (13) acts against rollers (16, 17) on the links, having a cam (14), superimposing an additional movement on the links to that of the support. This accurately positions a full container (3) on the magazine, and removes it when empty to the first station.

Title: Vacuum coating of substrates - on conveyor passing vacuum chambers with glow discharge polymerisation and metal vapour deposition
Inventor: BEHN REINHARD DIPL PHYS
IPC: C23C16/54
Filed: 1979-01-10
Abstract: Substrates receive alternately layers of glow-discharge polymer and of metal by passing them from one vacuum chamber with a glow discharge section to a second vacuum chamber with a metal evaporator via a vacuum lock. They are transported on an endless chain which runs over two sprockets and has in each straight strand a glow discharge section. The endless chain has carrier links with sealing blocks between them. This eliminates any possible contact of the substrates with air between the operational stages. Large and rigid substrates can be coated without excessive space requirements. The vacuum lock seals are more simple to produce than for plants with a revolving drum.

Title: Thixotropic silicate gels prepn. - for hydraulic disintegration of oil-bearing formations
Inventor: ELPHINGSTONE EUGENE ALBERT
IPC: C09K8/66
Filed: 1979-01-13
Abstract: Thixotropic gels for treatment of underground formations are made by reaction of an aq. acid soln. with an aq. alkali silicate soln. of pH over 11, in amount sufficient to give a gel with pH 7.5-8.5. Used for injection with high pressure and flow rate, after conversion to a h highly viscous liq. by shear forces, into oil-bearing rock formations to cause cracking and breaking up of the rock. The gels have excellent stability and retains their high viscosity over a wide temp. range, up to around 260 degrees C. They cause negligible reduction in permeability when used in low-permeability formation. Settling-out of supporting agents, e.g. sand, incorporated in the gel is prevented.

Patent DE-2910197-A1 (DE)
Inventor: RAGETTLI CHRISTIAN
IPC: B21D43/28
Filed: 1979-03-15
Abstract: The apparatus comprises a sheet metal shears at a cutting station which station is provided with a lifting table 13 which is vertically adjustable, is used for cutting off small sections of sheet metal from a sheet and also is used for stacking these sections on a pallet 15. This lifting table extends through a cut-out side wall 5 for the shears and thus permits the shifting of an already piled-up stack 16 away from the shears, and then upwardly so that an adjacent stack 16a may be piled up neatly in spaced apart relation with stacks separated from each other by at least the thickness of the cut-out side wall. The continuing movement of the lifting table 13 after erecting the first stack 16 causes a small drop at the cut-off sections which are placed on the pallet 15, so that an orderly piled-up stack 16a develops. As the height of the stack increases the lifting table is gradually lowered until the predetermined height of the stack is reached.

Title: Plastic tube coupling - using union nut with O=ring and split serrated wedge ring
Inventor: BUGATTI ERMETE
IPC: F16L47/04
Filed: 1979-03-19
Abstract: Coupling for tubes, esp. those made of polyethylene, nylon or PVC, is based on a union and a unit nut. The tube end is pushed into the socket of the union and held captive in it by screwing in the union nut. The sealing pressure is exerted by an O-ring, a washer and a split wedge-shaped ring with internal sawtooth serrations. The latter bite into the tube surface and ensure a reliable and durable seal. Coupling is easy to assemble and to dismantle and permits all parts to be re-used repeatedly.
