Title: Pipeless modular fluid transport housing - has components with passages between faces on common pitch circle
Inventor: KRUG HERBERT
IPC: F16L39/00
Filed: 1979-03-28
Abstract: The housing avoids the use of separate pipes when transporting fluids, having a number of modular components assembled together and with flange faces which can be sealed off, together with passages in the components for the fluid between these faces. The mouths of the passages in the components and the intermediate discs are on a common pitch circle with radius centred on the lengthwise axis of the housing, about which the components and discs, having similar or different hole patterns, turn. The components can be assembled if necessary with disc, to form a unit so that one or more passages can act as a bypass in the lengthwise direction, by turning or inverting individual components or disc.

Title: Low-slung suspension for bus - has support frames curved over axles and with lateral guide wheels
Inventor: BINDER HELLMUTH DIPL ING
IPC: B62D1/26
Filed: 1979-04-12
Abstract: A low slung suspension for a bus has the axle linked to a support frame by two sets of elastic couplings in the centre of the frame at each side. The couplings allow small steering movements of the otherwise rigid axle for automatic guidance steering. The suspension has a low height, with the support frames bent over the axles. The guidance steering uses sensing wheels (39) set horizontally to roll along guides along each side of the track. This system is used for buses which can operate on ordinary roads as well as on special tracks.

Title: Programme controlled washing machine - uses microprocessors to derive parameters necessary to wash laundry using min. water, energy and time
Inventor: PANHANS SONJA
IPC: D06F33/32
Filed: 1979-05-21
Abstract: Domestic washing machine is operated by programme control using micro-processors to remove soil from washing with min. amt. of washing agents, energy, water and time. Optimal conditions are obtd. by providing the washing drum with a sensor which indicates the weight of laundry to be washed. On exceeding the preset value for a particular fabric a warning signal is generated before the drum is filled with water. With laundry articles having different water absorption rates the optimal suds level is determined from the amt. of water supplied and the water level reached. Data relating to the weight and absorption rate are used as control factors, among other parameters, in the subsequent washing cycle. Supply of washing agent is controlled by the actual vol. of water supplied to the drum, water hardness and the type of fabric to be washed. In the determination of the amt. of washing agent to be used use is made of an indicator forming a neutral complex. Time interval required for the formation of the complex is determined by sensors and data obtd. is used by computer to determine quality of suds required.

Title: Programme controlled addressing of computer system - has structure stored in ROM and selection controlled by memory cells
Inventor: BRUNS HARTMUT DIPL ING
IPC: G06F12/06
Filed: 1979-09-19
Abstract: A computer system has programme controlled inout of addresses for selection of system modules based upon serial, direct or parallel operating modes. The addresses are stored in ROM modules.

Title: Turbocharged IC engine dynamic additional charging - uses peripheral pressure pulses, generated in buffer chamber between compressor and engine cylinders by suction strokes
Inventor: HORVATH ATTILA DR
IPC: F02B27/00
Filed: 1979-12-15
Abstract: The energy, used for additional charging is supplied by the turbine by increasing the velocity of suction air column in front of the compressor during the period of low pressure in the buffer chamber. The velocity increase is related to mean velocity of the compressor air flow. The generated bimetric energy is converted in the buffer chamber into an additional charge pressure. In the engine a charge compressor is pref. allocated to individual cylinders, on the cylinder group. The suction manifold between the charge compressor (5) and cylinders forms the buffer chamber (12) with a volume of max. 3/2 of that of an individual cylinder. The suction branch (13) of each compressor has a volume, which is a multiple of that of the buffer chamber.

Title: Contact mechanism for twin railway signalling relay - has rounded sheet metal flaps on armatures, to form flat support trough at points of flap contacts
Inventor: KUEHN WALTER
IPC: H01H50/32
Filed: 1980-05-16
Abstract: The relay assembly consists of two identical relays in vertical arrangement. The relays are mounted on a common support and their armatures carry at their ends rounded sheet metal flaps for supporting the contact systems of both relays in either of the two switching positions. The flap of the relay in rest position forms an interlocking bolt for the other flap at right angles to the first one. Thus the contact systems of both relays are supported until the rest relay is energised. Both sheet metal flaps (70) form a flap trough (80) at the points, where they form the interlock for supporting the outer flap (7). The trough is flattered than the rounded end (8) of the flap securing the contact system (6) of the last disconnected relay (1). The trough is in the form of a cylinder, extending longitudinally over the supported flap.

Title: Gas cooled high temp. reactor with structural side shield - built of segments connected at bolted joints
Inventor: ELTER CLAUS DR
IPC: G21C11/06
Filed: 1980-07-19
Abstract: A gas-cooled, high-temp. reactor, esp. pebble bed reactor, has its core surrounded by top, bottom and cylindrical side reflectors of graphite blocks; the radial outward forces from the side reflector are transmitted by support elements to the surrounding thermal side shield. This cylindrical side shield is built up from a number of annular segments fitted together with keyed butt joints (26,25) and each having an outward projecting flange (28) at the joint; the abutting flanges are bolted together by bolt connections each composed of a necked-down bolt (30) two nuts (32) and two washers (31); the form of the nuts and washers is such that the bearing surface (33) beneath each washer is kept small and as near as possible to the throat (34) of the flange (28). The side thermal shield is constructed to fulfil its structural function of withstanding the radial outward forces transmitted from the side reflector but is nevertheless built up from comparatively small and easily handled segmental components. The arrangement of the bearing surfaces (33) as close as possible to the throat of the associated flange reduces the bending moment occurring in the segments due to the bolted joints.
