Title: Two-component injection moulding process for manufacturing plastic strips, covers and the like
Inventor: MAYER GERT
IPC: B29C45/16
Filed: 1982-10-27
Abstract: The invention relates to the manufacture of two-component plastics injection moulded strips and like parts, which are preferably used in automobile manufacture. Strips of this kind were hitherto manufactured by the coextrusion process, where the freedom of design was limited by the fact that not any desired shape could be manufactured. The object was achieved by the fact that the time cycles of mould, machine and injection were matched to each other by means of a rotatable, pivotable and removable injection mould that is mounted on a special two-component injection moulding machine, in such a manner that, for example, the rigid PVC medium for the main strip, which is injected into the parting plane, is connected shortly after forming a surface skin to the soft PVC medium injected into the mould centre. With this mode of operation one or more soft lips or other shapes can be injection-moulded on. It is additionally possible by this mode of operation to inject covers with seals or other parts of complicated design by a two-component process.
Patent DE-3240129-A1 (DE)
Title: Device for closing two-wing trellis doors with clasp levers
Inventor: SCHILD WILLI
IPC: E05C7/04
Filed: 1982-10-29
Abstract: The device for closing two-wing trellis doors with clasp levers according to the invention is aimed at making the hitherto necessary retention of one of the door wings during the closing of the door superfluous. This is achieved, according to the invention, in that there is fastened rigidly in the middle of the pivot axle, to the two ends of which the clasp levers are fastened, a disc having a recess, into which, with the clasp levers closed, the locking bolt of the lock in the other door wing engages during the closing of the door. This ensures that the clasp lever cannot be swung up out of the locking position.

Patent DE-3347930-A1 (DE)
Title: Circuit arrangement for a flyback converter switched-mode power supply
Inventor: PAULIK ERNST
IPC: H02M1/36
Filed: 1983-11-18
Abstract: The flyback converter contains a switching transistor (Tr1) which is driven by an integrated circuit (IS). This circuit receives its supply voltage during the blocking phase from a winding (supply winding 3/4) on the primary side. A further winding (control winding 5/6) on the primary side supplies the control variable for the integrated circuit (IS) during the flow phase. It is proposed to connect the supply input (9) of the integrated circuit (IS) via a transistor (Tr2) and a diode (BY 360) to the control winding (3/4), and to bias the transistor base via a zener diode (Z11). In the starting phase, in which the voltage of the supply winding (3/4) initially builds up, this circuit supplies the required operating voltage, and switches off again when the power supply is in the steady state. Main field of application: switched-mode power supplies with an expanded mains voltage range. <IMAGE>

Title: Reciprocating piston engine
Inventor: STRAHM ANTON
IPC: F01B13/04
Filed: 1984-01-11
Abstract: The invention relates to a four-stroke reciprocating piston engine, in which cylinder, piston, connecting rod and crankshaft are mounted so that they can pivot about an axis parallel to the crankshaft axis and the cylinder has a radial scavenging orifice, which runs along an adjoining fixed control valve body and in the process passes an intake slot, a closed compression zone, an ignition aperture, a closed expansion zone and an exhaust slot. In the engine it is thereby possible to dispense with the valve arrangement and the associated drive hitherto necessary. The reciprocating mass movement hitherto necessary is replaced by a uniform rotation of the cylinder-piston units along the control valve body.

Title: Process for fabricating a junction field effect transistor
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L29/812
Filed: 1984-01-26
Abstract: The invention relates to a process for fabricating a junction field effect transistor, in which the surface layer designed to pass the current has a reduced cross-section in the channel region. The invention consists in applying a photoresist mask to the initially uniformly thick surface layer of the first conductance type. Through a hole in said photoresist mask, the surface layer is reduced down to a residual thickness. Through the same hole of said mask imperfections are then implanted into the surface layer, which there give rise to the second conductance type. Finally the mask already mentioned is used as a contacting mask in the fabrication of the gate electrode.

Patent DE-3417623-A1 (DE)
Title: Circuit arrangement for the allocation of triggering pulses for thyristors, especially in half-controlled, single-phase bridge circuits
Inventor: ALBRECHT HANS DIPL ING
IPC: H02M7/521
Filed: 1984-05-12
Abstract: The invention relates to a circuit arrangement for the allocation of triggering pulses for thyristors, especially in half-controlled, single-phase bridge circuits. The aim of the invention is to supply triggering pulses to the thyristor which is located in the blocking direction, despite the use of only one pulse transformer on its own. This is achieved according to the invention in that a switching command which is derived from the sum of the anode-cathode voltage and pulse voltage drives a switching transistor which is located in the triggering circuit such that, in the presence of the blocking voltage on the thyristor, no triggering pulses can pass to the control electrode of the thyristor. The sum evaluation of the thyristor voltage and pulse voltage allows the triggering circuit to be released immediately, or slightly before the transition from the off state to the blocking state. In consequence, the thyristor can be triggered over the entire physically possible range. <IMAGE>

Title: Selection plate method for isolating organisms, organs or cell strains which are distinguished from others by production of particular substances
Inventor: KNOOP BERND
IPC: C12Q1/04
Filed: 1984-06-26
Abstract: The method is characterised in that selection plates with a particular structure are used: solidified nutrient medium covered with an accumulation film coated on one side, and with a thin cell support film. The substances which are released by organisms, organs or cells onto these selection plates do not disperse freely in the medium but bind locally to the accumulating layer. Whereas the biological material is lifted off with the upper thin cell support layer and is cultivated further, the released substances can be detected in the accumulation film. In this case, a flow of solvent directed through the film generates on its free reverse side a pattern, which is homologous to the organisms, organs or cells, of the particular released substances, which pattern can be visualised by conventional methods. This technique allows production of particular substances to be assigned to defined organisms, organs or cells on the cell support layer and thus permits selection and further culturing of producer mutants or variants from large populations.
