Title: Tool for precision boring predrilled bore - produces non-cylindrical bore using spindle carried in independently radially adjustable bearings
Inventor: SCHLETH JUERGEN
IPC: B23Q1/38
Filed: 1980-04-03
Abstract: The mechanism is intended for precision boring a pre-drilled bore to obtain a bore other than cylindrical, e.g. for optimising the bore contour for the gudgeon pin bearing in an i.c. engine piston. To this end the drill spindle (2) is adjustable at an angle to and/or parallel relative to the rotational axis of the drilling machine. The spindle may be carried in at least two radial bearings (5,6) which are independently adjustable in radial direction. This may be effected by admitting controlled oil pressure to pockets (7) in one bearing bush and to pockets (8) in the spindle portion carried in the other bearing (6).

Title: Through hole insulation - for metal core printed circuit board, by evacuation, heating and pressure application
Inventor: NEUBERT KLAUS
IPC: H05K1/03
Filed: 1980-07-18
Abstract: When printed circuit boards (PCB) consist of a central aluminium core with a bilateral coating of glass fibre reinforced epoxy resin, any through bores must be carefully insulated. This is done by placing such a PCB in a vacuum chamber to remove the air from the bores, at a pref. vacuum of 5-50 Torr (10 Torr). The foil is heated to 100 deg.C to fuse the epoxy resin and when the chamber is reconnected to atmosphere, the air causes the resin to flow into the through bores. A hardening process at 180 deg.C and 10-20 bar completes the operation. This prevents any bubbles from adhering to the through bores.

Inventor: ELTER CLAUS DR ING
IPC: G21C1/07
Filed: 1980-12-18
Abstract: Ceramic components, esp. assembled blocks constituting the bottom support for a nuclear reactor and resting upon a bottom plate are intended particularly for reactors where the core is composed of loose spherical fuel elements (pebble bed reactor). The horizontal bottom support carries the side reflector and/or the bottom reflector via support elements. Between the blocks (18,18a) of this bottom support, the joints (19) are stepped. Specifically, the blocks have projections (24) and recesses (25) engaging one into the other. The joints (19) may taper from the top face (20) towards the step (31). Pref. width for the joints (19) at the top (30) is approx. 12mm. Used for a gas-cooled, pebble bed reactor. During the life of the reactor considerable dust is produced in the core, partic. due to abrasion of fuel elements on the reflector.

Title: Mixture-compressing internal combustion engine with applied ignition
Inventor: BINDER ROBERT
IPC: F02B23/08
Filed: 1981-03-20
Abstract: A mixture-compressing internal combustion engine with applied ignition and valves arranged suspended and inclined towards the cylinder axis comprises a combustion chamber, which is formed by a recess in the cylinder head and by a recess in the piston head, and a quench area formed by a part of the end face of the cylinder head lying perpendicular to the cylinder axis and a corresponding part of the piston head surface also lying perpendicular to the cylinder axis. In order to reduce the fuel consumption and to reduce the exhaust gas constituents CO, HC and NOx, the combustion chamber shape is designed in such a way that the recesses in the piston head in at least one plane have a circular cross-section with a radius from 30 mm to 70 mm, the quench area has a size of 15% to 35% of the piston head surface, and the valves are arranged inclined at an angle of 10 DEG  to 30 DEG  to the cylinder axis.
Patent DE-3111971-A1 (DE)
Title: Fuel saving device
Inventor: ALBRECHT FRANZ
IPC: F02M3/10
Filed: 1981-03-26
Abstract: In motor vehicles with internal combustion engine overrun cut-off is possible in order to save fuel. For this purpose, when coasting and braking, the fuel feed to the engine is interrupted, in that in a carburettor engine a solenoid-actuated shut-off valve in the fuel line of the carburettor is closed. In so doing, however, the supply of fuel present between the shut-off valve and the carburettor nozzles can still be drawn in by the engine. With the new fuel saving device, the shut-off element (86, 96) in the idling nozzle and under some circumstances also in the main nozzle, is combined with the nozzle needle (89, 93). The now freely movable nozzle needle (89, 93) with the valve body part (86, 96) is drawn by a solenoid (85) against an adjusting screw (90), by means of which the operating position of the nozzle needle (93) is adjusted. When the solenoid (85) is switched off, the valve body part (96) of the nozzle needle is pressed by means of a closing spring against the valve seat (97), thereby shutting off the fuel line. This occurs immediately upstream of the point at which the fuel passes into the intake line. Any trickling of fuel is thereby prevented. <IMAGE>

At its front end, the control ring (22) has a sealing face (43) extending only over a section of the periphery and closing the control passages (25) over this section of the periphery. <IMAGE>

Title: Cassette recorder with built-on and removable container for storing music cassettes and power cable
Inventor: BARTELT HANNES
IPC: G11B23/02
Filed: 1981-06-12
Abstract: Cassette recorder with built-in and removable container for storing music cassettes and power cable etc. Until now, if a number of cassettes were to be stored and taken along, a separate container or case was always required, which was inconvenient. The problem is now solved by there being provided on the recorder a container in which at least four music cassettes can be stored and removed at the press of a button. One cassette compartment serves for receiving the power cable, spare battery etc. Thus, it is no longer necessary to take along a separate container or case for these cassettes.

IPC: B21B21/00
Filed: 1981-07-23
Abstract: In cold pilger machines, the mandrel bar, which is driven by a feed and rotation device, must be secured against lateral buckling. For this purpose, use is made of longitudinally movable supports, each of which has a guide opening.
