Title: Determining changes in rubber materials by mechanical tests - using intermittent loading and monitoring reversible and irreversible changes
Inventor: GADDUM FRIEDBERT ING GRAD
IPC: G01N3/32
Filed: 1976-10-07
Abstract: Changes in materials are measured bythe discontinuous load relaxation method or intermittent loading/relaxing with a short rest period. Irreversible chemical and physical changes in specimens are shown by registering and then eliminating the parallel reversible changes in the test procedures described. Alternatively, the procedures enable reversible changes to be monitored with and without irreversible factors. The tests can be various types of mechanical loadings. The travel speed in the forward and backward loads is selected so that the deflection in the test specimen with small relaxation times do not significantly vitiate the measurement of its elastic deformation. The test equipment permits investigation of plastic materials with a permanent electrical field, temp. or strain cycles can be exactly programmed, freezing points can be determined, degree and speed of crosslinkage and of ageing can be measured in one operation.

Title: Compression helical torsion spring for door hinge - is positioned between stop and hinge plate rotated about longitudinal axis of pin on stop
Inventor: KAISER KENNETH L
IPC: E05F1/12
Filed: 1976-10-08
Abstract: The hinge has a stop and a bracket moved on the stop between an open and closed position. The stop has cams for lifting the bracket on rotation into door open position and the bracket is lowered on rotating into closed position. This arrangement significantly increases the door closing force. A helical torsion compression spring (68) is compressed longitudinally when hinge plate is lifted. This spring is held by one end (76) on the stop and its other end (72) on the hinge plate. The latter is rotated about the longitudinal axis of the pin (34) on the stop. The upper slotted end (42) of the pin engages with upper end (76) of the spring (68). A protection cap (48) on the slotted pin encloses the spring.

Title: Polarisation colour filter device - has specific polarisation optical elements for filtering or separating discrete laser lines of laser beam
Inventor: SCHROEDER ECKHARD DIPL PHYS
IPC: G02B27/28
Filed: 1976-11-04
Abstract: A polarisation colour filter is used for separating discrete spectral lines of a laser beam. It has polarisation specific optical elements. A colour dispersive optically active crystal is used which as a function of its thickness changes the polarisation state of specific laser lines differently through a rotation of the polarisation directions. The polarisation directions are determined by means of polarisation specific optical elements for filtering, or separating the lines. A quartz body (Q) with the optic axis positioned in the direction of the laser beam rotates the polarisation direction or plane of a light beam by an angle which increases linearly.

Title: Inert material charge sleeve for mining explosive - is jammed by wedging into borehole against explosive charges
Inventor: ZEISSIG ORTWIN M
IPC: F42D1/18
Filed: 1976-11-05
Abstract: The inert material charges are used in conjunction with explosive charges in mining. The explosive and inert charges are placed into borehole. The inert material, such as water loaded flexible sleeve is pushed into borehole where it is tightly jammed due to distortion caused by a weakened part in sleeve wall. The sleeve is buckled and jammed into borehole. The water holding sleeve is held in boreholes correctly and with adequate jamming force. The sleeve is pushed as straight unit up to the charge 23 in borehole. Additional force is exerted on the sleeve rear end (22) until the rear end is pushed at the weak point over the front part. The weak flat part folds and allows the rear part to be wedged between borehole wall and front part of hose.

Title: Modification of semiconductor pref. silicon sheet crystal structure - by zone melting in atmos. contg. oxygen, gives prod. useful in solar cell
Inventor: BAGHDADI ASLAN
IPC: H01L31/18
Filed: 1976-12-29
Abstract: Modification of the crystal structure of a semiconductor esp. in the form of a sheet or strip, involves producing a melt zone in the materials, which extends over the surface from >=1 edge, in an oxidising atmos. and passing the melt zone along the material. The atmos. used should contain >=4 vol.% O2 and pref. is air. Polycrystalline Si can be converted into monocrystalline Si suitable for making solar cells and for other electronic applications reliably and at high throughput and low cost. For 0.25 mm thick sheet, the melt zone can be 2.5 mm or more wide without instability problems if an atmos. contg. O2 is used, of =0.25 mm with an inert atmos. The process can be repeated with the melt zone moving in a different direction. The sheet or strip is moved vertically past a heat source, which pref. is a laser beam vertically past a heat source, which pref. is a laser beam defocussed to the required extent to produce the melt zone.

Title: Chuck with hydraulic tappets in jaws - has pressure dependent valve in pipe between radial jaws preset by lead-screw
Inventor: SCHMID ERNST
IPC: B23B31/16
Filed: 1977-03-10
Abstract: The chuck has two and pref. three jaws adjustable in relation to each other, there being self-compensating clamping pins in their faces towards each other in the form of hydraulic tappets coupled together by a compensating pipe. In the pipe (10) between two jaws (3) is a pressure-dependent closing valve (15).

There can be more than one hydraulic tappet (5) in each jaw, those in the same jaw being directly connected hydraulically. The jaws can be adjustable together in the radial direction mechanically by a square-section screw thread. The hydraulic fluid unions can be situated at opposite ends of each valve.

Title: TV line deflection circuit with east-west pincushion correction - has impedance switched in and out at line frequency between line transformer tap and junction of deflection coil and correction coil
Inventor: MANDL PETER
IPC: H04N3/16
Filed: 1977-07-16
Abstract: East-west pin cushion correction is effected by a switch comprising a thyristor-diode combination. The change of the line output thyback resonance frequency caused by the periodic opening and closing of the switch is prevented by the insertion of an impedance, e.g. a capacitor, between the line output transformer and the junction of the series-connected line deflection coil and the east-west correction coil. This impedance is switched in and out at line frequency. The impedance may be connected to a tapping on the primary winding of the transformer or to an auxiliary winding on the transformer. Operation of the east-west correction circuit may periodically connect the impedance in parallel with the line deflection coil.

Title: Vacuum cleaner, especially for household use - has separate cool air fan, for cooling motor housing
Inventor: WOERWAG EBERHARD
IPC: A47L5/22
Filed: 1977-09-03
Abstract: The vacuum cleaner, especially for domestic use, uses the current of air supplied by the fan as well as cool air current especially produced by its own cool air fan for cooling the machine.

Title: IC engine low pressure fuel injection system - has fuel distributor rotor displaced hydraulically, to meter fuel corresponding to engine requirements
Inventor: NOGUCHI MASAAKI
IPC: F02D3/00
Filed: 1978-06-05
Abstract: The fuel injector pump consists of a housing provided with a low pressure fuel inlet union and a number or outlet unions corresponding to the number of injectors to be fed. The housing contains a fuel distributor rotor turned in synchrony by the engine. The rotor can be displaced axially by hydraulic pressure to meter the fuel via triangular slots. The hydraulic displacement of the rotor is controlled by an electronic regulator receiving impulses from an oxygen sensor located in the exhaust system, an air intake volume transducer located upstream to the throttle flap and an engine temp. sensor. The rotor displacement medium is fuel whose flow and return is regulated by two electro magnetic valves opening and closing in response to signals transmitted by an electronic regulator.
