Title: Hydrodynamic bush bearing with axial oil pockets - has cylindrical end portions to limit axial escape of oil
Inventor: PESSEL ERICH
IPC: F16C33/10
Filed: 1976-06-28
Abstract: The bearing bush has a bush whose bearing surface has lobe-shaped pockets (4-7) for the hydrodynamic formation of wedges of oil. The pockets extend circumferentially between arcuate portions (10-13) centred on the axis of the bearing. Axially, the recesses extend short of the ends of the bush and terminate at cylindrical end portions or weirs (9). The weirs limit or prevent the escape of oil from the axial ends of the pockets. The weirs may extend over the whole inner circumference of the bush or only at the lower half of the bush.

Title: Cooking animal material, e.g. fish (waste) - using a heated liq. in a vertical column partly cocurrent and partly countercurrent with continuous reversal
Inventor: TRONSTAD INGE MAGNUS
IPC: A23K1/10
Filed: 1976-07-08
Abstract: The process comprises (a) pumping the matl. from a storage vessel through a pref. vertical cylindrical reactor into a lower heating zone maintained, by liq., at a temp. sufficient to initiate coagulation of the proteins in the matl., and (b) advancing the matl. to a reaction zone situated above the heating zone at a constant or slightly falling temp. for the completion of the protein coagulation. Pref. heated liq. can be supplied to or withdrawn from posns. in the heated zone of the reactor such that the hot liq. flows. in one section of the zone in co-current and in a further section in countercurrent with flow of the raw matl. through the reactor. The feed and discharge positions are interchangeable. The system gives an easily regulated, continuously operated cooker in which rate of flow, temp. pressure, pH, etc. can be controlled. No burning-on of solid deposits on very hot heat exchanger surfaces can arise. The appts. is easily cleaned and being vertical requires min. floor space.
Patent DE-2637788-A1 (DE)
Title: Machine for grinding concentric faces on small round workpieces - in which workpieces are carried in cage past grinding wheel
Inventor: MODLER HANS DIPL ING
IPC: B24B5/32
Filed: 1976-08-21
Abstract: The cage which carries the workpieces is mounted concentric to a disc which rotates the workpieces. In e.g. an arrangement in which the conical seating faces (2) of jet valve needles are to be ground concentric to support faces (A) which are also conical, the needles are mounted in a cage between two discs. The first disc (5) which is a spring disc, rotates in the opposite direction of a drive disc (6) but a little faster. This ensure that the needles are tipped over their support points in the cage. The needles will be stably supported with their cones against the grinding wheel (30), while at the same time they rotate rapidly. The support points for the needles in the cage are so arranged, that the axes of rotation of the workpieces are inclined by a small amount with reference to a radius. This arrangement ensures an axial infeed of the workpieces.

Title: Electropolishing back side of information-carrying matrix - to prevent transfer of unevenness to front side
Inventor: KOOP HERMANN DIPL CHEM DR RER
IPC: C25F3/22
Filed: 1976-09-27
Abstract: Smoothing of the back side of a galvanoplastically produced press- or stamp-matrix for a plate- or foil-like information carrier is carried out by electrolytic polishing in a H3PO4-H2SO4 bath, whilst the front side of the matrix is protected by a removable, elastic, acid-resistant film based on a polyvinyl resin. The bath pref. contains 50% H3PO4, 40% H2SO4 and 10% water. Chromic acid can be added. The electropolishing can be preceded by mechanical polishing. The removal of unevennesses formed on the back side of the matrix during the plating prevents eventual transfer of the unevenness to the front side of the matrix.

Title: Radio receiver with microcomputer - generating control signals for input and main tuning circuits and controlling changeover
Inventor: OSMERS HERBERT
IPC: H03J3/24
Filed: 1978-04-05
Abstract: The radio receiver has electronically tuned input and oscillating circuits. The control voltages or currents for both tuning circuits are generated by a microcomputer taking synchronisation conditions into account. The microcomputer also generates a change-over command that changes over the frequency sub-band of the input circuit or circuits at least once when the oscillating circuit's frequency band is passed through. The oscillating circuit's frequency is obtained by frequency synthesis whilst that of the input circuit is obtained by voltage synthesis under the control of the microcomputer.
