Title: Wide dia. range pipe wrench - has slot with indented walls to give different jaw openings
IPC: B25B7/02
Filed: 1977-06-23
Abstract: A pipe wrench (10) with adjustable jaws to suit a wide range of dias. of pipes has two arms (11, 12). The arm (11) has a serrated surface (17) forming the teeth of one jaw and an elongated slot (28) with rounded ends and curved recesses (30) along each side. The arm (12) also has a serrated surface (13) which forms the opposing jaw and a pin (27) of semi-circular cross-section. The curved surface of the pin (27) matches the curvature of the recesses (30) in the slot (28). This enables the pin (27) to form a pivot in any of the recesses (30) and so give a range of jaw openings to match a wide range of pipe dias. with an increased leverage on the larger dia. pipes.

Title: Vehicle safety belt winding up mechanism - has cam bringing catch into initial engagement with toothed ring
Inventor: HILDEBRANDT ECKHARD DR ING
IPC: B60R22/405
Filed: 1977-12-05
Abstract: A locking device prevents unwinding of the speed exceeds a set value. An inertia body rotating with and on the shaft lags to bring via a cam a locking catch swinging radially on a shaft flange into engagement with a toothed ring fixed to the housing. A vehicle-sensitive locking device has an inertia weight moved by acceleration above a predetermined level far enough out of the rest position to secure the body and thus lock the shaft, by means of a locking lever in a stationary bearing. When this lever (37) secures the inertia body (23), a control cam brings the locking catch in a first phase only into initial engagement with the toothed ring (9, 9a). In a second phase, the resultant tangential force frees the catch from the cam, swinging it further into full engagement with the ring.

Patent DE-2810035-A1 (DE)
Inventor: BOOSS HANS-JUERGEN DIPL CHEM D
IPC: C08K5/05
Filed: 1978-03-08
Abstract: The invention relates to filler-containing reaction-curable resin compositions based on epoxy resins for the production of components for SF6 circuit breakers and high-voltage compounds (switchgear). The fillers are improved in that the epoxy resin moulded materials produced therefrom have both adequate mechanical stability and are resistant to SF6 decomposition products. To this end, the reaction-curable resin compositions contain from 50 to 70% by weight of dolomite (based on the total weight, including the crosslinking component), whose particle size corresponds at least to the crystallite size and - based on dolomite - from 0.1 to 3.0% by weight of a processing auxiliary in the form of a higher monohydric or dihydric alcohol. The moulded materials according to the invention are used, in particular, in components such as post (pin) insulators and bushings.

Title: Compact gas turbine for saw or lawn mower - has central inlet bladed centrifugal rotor compressing over half revolution and acting as turbine over other half
Inventor: MAYER KARL DIPL ING
IPC: F02C7/12
Filed: 1978-09-19
Abstract: The compact gas turbine comprises a housing (1) contg. an eccentrically arranged bladed (4) centrifugal rotor disc (2) which is so arranged that air entering centrally to the disc is compressed over half its revolution and enters a combustion chamber (9). Over the remaining half, the rotor blades act as turbine blades being moved by hot combustion gas from the chamber. This prevents overheating of the blades and provides a heat exchange effect. A semi-circular baffle (5) may be provided to prevent fresh air from entering the turbine section and hot gas from entering the compressor inlet section.

Title: Three=dimensional control of switching circuits - uses three lines to operate one switch to save control circuits in telephone exchange
Inventor: LECHNER ROBERT DIPL ING
IPC: H04Q3/00
Filed: 1979-04-23
Abstract: With the object of reducing the number of control lines required, a large number of switching circuits are arranged in a three-dimensional array and controlled by three groups of control lines. Each switching circuit lies at the intersection of three control lines, one from each group. Each switching circuit may consist of a bi-stable polarised relay, its operating coil being connected in series with a triac between the associated X and Y lines. The triac trigger is connected to the associated Y line. Thus, one switching circuit is operated by momentarily applying +ve to one control line, -ve to another and trigger to yet another.

Title: Triple flow sensor system - has each probe pair in separate holder section with tips connected in bilaterally symmetrical arrangement
Inventor: ACRIVLELLIS MICHAEL DR ING
IPC: G01F1/69
Filed: 1979-09-15
Abstract: The triple sensor system determines the current or flow parameters. It has a number of probe elements, whose tips lie all in the same plane. The probe elements are grouped into three pairs. Each pair of probes is held in its own holder section and the lines joining the tips of the pair elements meet at a common centre.
