Title: Lathe chuck with tooth rack operated jaws - have toothed wedge bolts actuated by slide bush and disengageable for radial removal of jaws
Inventor: HIESTAND KARL
IPC: B23B31/167
Filed: 1979-10-03
Abstract: The lathe chuck (1) comprises radially slidable jaws (4,5) each having a tooth rack (7) engaged by teeth (13) on a wedge bolt (11). The wedge bolts, which are contained in tangential recesses (12) in the chuck body (2), can be moved so that their teeth are out of engagement with the racks to permit removing the jaws in radial direction. Operation is via a co-axially slidable bush (21) with projections (23) in inclined slots (31) of the bolts (11). Each slot (31) has a recessed portion at one end to receive the projection (23) when the bolt (11) is moved out of engagement with the tooth rack via a rotatable radial bolt (14) in the chuck periphery, with an eccentric pin (15) in a recess (16) of the bolt (11).

Title: Microcomputer-controlled generation of time code signals - using shift registers alternately switched into modulator coupled to head of magnetic tape recorder
Inventor: TRISSL KARL-HEINZ DIPL PHYS
IPC: G11B27/32
Filed: 1979-10-26
Abstract: A microcomputer is used to generate time code data for recording on magnetic tape. The microcomputer transmits time code data serially to two 16 bit shift registers. The outputs of the shift registers are alternately applied to a modulator over a data switching stage. The generated time code data are transmitted to the audio head of a magnetic tape recording system. The shift register stages are clocked by data switches that receive clock inputs from the microcomputer and signals generated by a counter driven by a time code clock source operating at 2 KHz. The counter also drives an input circuit coupled to the microcomputer.

Title: Spoiler flap for rear of car - has pneumatic bellows to control hinged flap over rear edge of boot
Inventor: SOEDERBERG RICHARD
IPC: B62D35/00
Filed: 1980-02-01
Abstract: The spoiler flap (14) is mounted on the rear edge of the boot and has a raising rear edge to trim the vehicle at different speeds. It has a bellows servo (13) normally folded in a recess under the flap and operating with vehicle speed to stabilise the vehicle at high speeds. The bellows operate against a return spring (25) which holds the flap flush with the boot lid when the car is at low speed. The flap provides a compact and simple trim control which does not impair access to the boot. The flap hinge can be simplified by using an elastic flap hinge with both ends bonded to the flap or vehicle. The flap can be replaced by a series of flaps along the rear edge of the boot for improved trim control.

Title: Rolled stock lateral transport skid - has parallelogram linkage controlling reversing operation at any point of lateral motion
Inventor: SIMON KARLHEINZ
IPC: B65G25/10
Filed: 1980-06-24
Abstract: The individual skids of the skid assembly (1) are aligned in one row and can be moved simultaneously along rails (30) in either direction using a cable line (2). The rolled stock (W) is moved by protruding stops (10). Underneath the rails a pull rod (20) is operated by a hydraulic power cylinder assembly.

Title: Relay visible position indicator - has arm pivoted on coil, moved by armature one end, indicating position at other end
Inventor: HOEHLEIN GERHARD
IPC: H01H50/08
Filed: 1980-07-24
Abstract: The relay with a visible position indicator has a cover (4) with a lens shaped window (4) through it, so that the end (9) of a swinging arm (5) inside can be seen. The arm is a swinging arm, resting on top of the coil (1) and moved by the action of the armature (3) above it. This arm is of a resilient plastics material and is formed by two V-shaped parts. The larger V (5a) carries the indicator part (9), and has a return spring (12) holding it down. The smaller V (5b) the other end has it apex (11) nesting on the coil, forming the pivot point of the whole arm. A number of alternative designs incorporate alternative return springs. The spring may be a resilient extension of the arm itself, at the other side of the pivot point. It may be a spring retained between the arm and the armature, or a wire spring attached to the frame.

Title: Axial-piston-movement positive displacement machine - converts piston motion to rotation using annular axial cam and desmodromic follower arrangement
Inventor: MONATH AUGUST DR ING DIPL ING
IPC: F01B3/04
Filed: 1980-07-25
Abstract: The axial piston-movement positive displacement machine uses an axially-profiled cam ring to convert piston motion into piston-axis-parallel rotation. The ring has a profiled face which slopes outwards; below it there are grooves in both wall surfaces running parallel with the profile. Power is transmitted between piston-rod and ring via flanged conical rollers and pivoting-arm mounted roller-followers engaging the grooves. The roller spindle-ends slide in slots parallel to the piston rod. The working-stroke part of the cam surface covers a substantially larger angle than that for suction- and compression-strokes.

Title: Ice and smooth snow thawing agent contg. magnesium or calcium chloride - in porous mechanical neutralising agent to prevent caking and extent effect
Inventor: BUDICH MEINRAD
IPC: C09K3/18
Filed: 1980-07-26
Abstract: Melting agent for ice and smooth snow areas is based on substances (I) lowering the m.pt., i.e. MgCl2 and/or CaCl2, and mechanical neutralising agent (II), (II) being a porous material with (I) embedded in its pores. Pref. (II) consists of pumice or Ca silicate. The agent can also contain a dyestuff, corrosion inhibitor and artificial fertiliser and/or other plant nutrients. Although (I) are very hygroscopic, (II) prevents caking. The effect of the agent is extended, since (I) are released slowly. MgCl2 is nontoxic and chemically neutral. The amt. of (I) needed is less than with NaCl and (I) cause less corrosion and environmental pollution.

Title: Igniter assembly for explosive shell - has plunger with two locking systems released by spin, and has striker holder released on impact
Inventor: BACKSTEIN GUENTER
IPC: F42C9/18
Filed: 1980-10-04
Abstract: The nose cone (22) for an explosive shell has a small charge (29) at the rear, preceded by a detonating charge (23). The latter is mounted in a cylinder (20) which can be tilted to bring it into alignment with a firing pin (16). The pin can be forced into contact with the detonating charge when a plunger (11) is forced backwards by a spring (13) in the nose, on impact. The plunger is prevented from operating in advance by vibration or shock by a system of locking balls (6,9). The cylinder is prevented from rotating by an axial pin (18) with a hollow interior holding a spring (19), which remains in a locking position in a groove in the cylinder until released by impact. The locking balls also travel along a system of sloping channels (e.g.7) due to the spin of the shell after firing so that the plunger is released. A second device also released by the spin is a band (1) supported by carriers (2,3) wound around the plunger.

Title: Current feed member for bus=bar - has support ribs with one of greater thickness which has part secured on current feeder bolt and forms integral part with thinner rib
Inventor: JUNGBLUT CLAUDE
IPC: H01R25/14
Filed: 1980-10-08
Abstract: The busbar has a U-shaped cross section with inner contact strips in longitudinal direction, insulated against the busbar proper. These strips are not insulated against the U profile inner space. Light fittings etc. can be inserted on the strips via appropriate adaptors. The current feeder has a bolt which can be inserted in the front side of the busbar and which carries sheet metal contacts, applicable to the contact strips. Into busbar guides are inserted support ribs of the current feed which prevent any connecting errors. The greater thickness support ribs are formed by a portion (17) secured to the bolt (10) of the current feed member (9). One support rib (16) of smaller thickness is integrally formed on this configuration. The support rib portion (17), turned through 180 deg. forms the thicker support rib with the thinner one. This portion also carries terminal markings.

The new cpds. can be used for combatting protozoal diseases, in humans and animals, e.g. amoebiasis due to Entamoeba histolytica. In addn., the cpds. have a direct or (due to interferon-induction) indirect activity against influenza and encephalomyocarditis viruses. On account of their interferon-inducing activity, the cpds. can be used against virus and cancer diseases. In addition, the new cpds. (esp. those in which R3 is OH) are effective against trichomoniasis.
