Title: Conversion unit for osteosynthesis implantation unit - has horseshoe shaped body surrounding cylindrical member enclosing pick=up coil with side contact electrode
Inventor: KRAUS WERNER DIPL ING
IPC: A61B17/58
Filed: 1978-06-12
Abstract: The osteosynthesis unit comprises a body (222), typically of horse-shoe shape with a longitudinal side contact electrode (236/a). Along the centre-line is a pick-up coil (227) supported by short plastics tubes. The coil also surrounds an osteosynthesis plate and is enclosed in a hollow sheat needle (210). The side contact electrode (236a) is insulated from the sheath needle by insulating shoulders (230) forming part of the main body (22). To the windings of the pick-up coil are connected two electrically connected electrode fitted near the ends. The implantation unit converts a conventional osteosynthesis device into an electro-synthesis unit. The unit is adapted to various shapes and designs and may be used during the course of an operation to assess the healing capacity of a patient.

Title: Hydraulic device pressure regulator - has piston moved by fluid pressure against spring to selectively vent fluid and control pressure
Inventor: KAMENECKIJ GEORGIJ IOSIFOVITSC
IPC: G05D16/10
Filed: 1978-06-28
Abstract: The pressure regulator for a device e.g. on a machine tool, has a bore in which slides piston (13). This is biassed by an adjustable spring (6) and is coupled by a pivoted lever (4) to an electric switch (5).

Title: Cast iron furnace hearth grating - with flat beams on edge joined by flat strips on both faces
Inventor: WICKER HELMUT DIPL ING
IPC: F27D3/02
Filed: 1978-09-13
Abstract: The grating for the hearth of a heat treatment furnace consists of a grid-like frame, made of castiron, on which the workpieces are transported through the furnace. The grating consists of several parallel carrier beams of rectangular cross-section, standing on edges. They are joined in pairs by flat pieces at both face ends to link one beam alternately to the one on the left and to the one on the right. This eliminates the accumulation of metal at the junction which leads to cracks in conventional grating when dipped together with the workpieces into a quenching bath.

Title: Winch for wet-treatment of textiles - having a single driven roller within a vessel with asymmetrically sloping floor
Inventor: SCHUIERER MANFRED
IPC: D06B3/26
Filed: 1978-10-24
Abstract: Appts. for the batch wet-treatment, partic. dyeing, of textile material in the form of an endless loop comprises a closed container with a winch in the upper part for circulating the material, the bottom part forming a trough which holds the dye liquor, and merging smoothly into the end walls, forming at the material input end of the trough a smooth, Teflon-coated ramp whose upper end is higher, and also further from the lowest point of the trough, than the material output end of the trough. The shape of the trough ensures a smooth, snag-free circulation of the material, without the need for extra driving elements in the liquor bath, which would mean increased expense and maintenance work; and it allows a comparatively low liquor ratio to be used.

Title: Centrifugal liquid homogeniser - with liquid speed reducing means facing reaction nozzles on rotor
Inventor: LUKJANOV NIKOLAJ JAKOVLEVITSCH
IPC: B01F25/64
Filed: 1979-06-01
Abstract: A centrifugal homogeniser for liquids such as milk or milk prods. uses a hollow rotor with two reaction nozzles through which the liq. is discharged at a high velocity. This velocity is reduced immediately by letting the jets impinge on a corrugated surface on a stationary ring or on vanes attached to the rotor.

Title: Hydraulic fracturing technique - with multiple fracturing cycles using fine-sized and then medium-sized proppant
Inventor: PERLMAN WILLIAM
IPC: E21B43/267
Filed: 1979-08-16
Abstract: The hydraulic fracturing of subterranean formations comprises using multiple fracturing cycles to generate vertical linear fractures or linearly extending fractures outward from the point of introduction of the fracturing fluid. The method involves introducing into the formation a series of slugs of proppant-carrying fracturing fluid carrying fine-sized proppant in amts. of >=5 lbs/gal., with proppant-free spaces slugs being introduced between the stages. Both fracturing fluid and spaces are injected at rates of 25 bbl/min., and injection is continued until >=25000 lbs. fine-sized proppant have been deposited in the formation per each foot of available net producing interval. The formation of radial vertical fractures is eliminated. The linear fractures created are much wider than those made by prior art methods, and considerably higher amts. of proppant are deposited.

Title: Automatic and manual linear reversion control mechanism - has pins slidable on control bars of manual and automatic mechanisms and selector to engage one and disengage other
Inventor: HSU WILLIAM WEI
IPC: B64C13/42
Filed: 1979-08-20
Abstract: The automatic and manual linear reversion control mechanism for a hydraulic servo actuator assembly is for linearly transferring control between an automatic control mechanism and a manual control mechanism. A command select mechanism includes two axially aligned pins mounted on a rigid command selector bar. The first pins is slidably in a slot in a control bar of the manual control mechanism. The second pin is slidably in a slot in the control bar of the automatic control mechanism. Thus movement of the command selector bar displaces the two axially aligned pins in their associated slots provides a linear transfer of control of the hydraulic assembly between the manual and automatic control.
Patent DE-2935525-A1 (DE)
Title: Electronic multiple phase DC tachogenerator arrangement - uses AC tachogenerator with phase sensitive amplifier and changeover circuit
Inventor: LAYH HANS DIETER
IPC: G01P13/04
Filed: 1979-09-03
Abstract: An electronic multiple phase d.c. tachogenerator overcomes the problems of high cost, large size, and brush wear associated with such devices. This is achieved by using electronic circuitry in conjunction with an a.c. tachogenerator to produce a voltage proportional to the revolution rate and whose sign is dependent on the direction of rotation. A phase sensitive amplifier connected after the rectifying circuit, which can be electrical or electronic, detects the change in phase resulting from the change in rotation direction. A signal corresp. to the change in phase is fed to a change-over circuit which reverses the rectified tachogenerator voltage. The polarity reversal can either be reversed by an electronic amplifier with phase inversion or a relay, e.g. a rapid reed relay.

Title: Agents for controlling caries - contg. antibacterial enzymes, e.g. lysozyme or dextranase, in immobilised form to prevent dilution by saliva
Inventor: ZECH RONALD PROF DR MED
IPC: A61Q11/00
Filed: 1979-09-20
Abstract: In new agents for combating caries contg. as active substance a bacteriolytic or bactericidal enzyme (esp. lysozyme or dextranose), enzyme is immobilised on a carrier material or at least one binding material is present to bind the enzyme molecules with each other or couple them with a carrier material. Immobilisation of the enzyme renders it insoluble, so that it does not become dissolved in the saliva and thus diluted and removed from its site of action. It becomes possible to locate the enzyme in the oral cavity and maintain an effective concn. day-long.
