Title: High speed line printer with rotating type roller - has printing magnet for each pair of printing columns
Inventor: MAEDGE WERNER
IPC: B41J1/34
Filed: 1975-04-12
Abstract: The high speed line printer has a printing magnet for each pair of printing columns and a movement transfer bar for each magnet to transfer the movement of the magnet's hinged armature to the two-armed lever on one arm of which a type wheel freely rotates.

Title: Vertical deflection circuit for TV receiver - derives precisely shaped and phased blanking pulses from flyback pulses
Inventor: WOELBER JOERG ING GRAD
IPC: H04N3/24
Filed: 1975-07-26
Abstract: The vertical deflection circuit, for a television receiver, obtains its blanking pulses from the shorter flyback pulses and imparts a precise shape, duration and phase to these pulses without involving the disadvantages of normal RC circuits. The output of a first diff. amp. acts as blanking pulse. One input of a second diff. amp. is connected to a capacitor and its second input is connected to a higher reference voltage than the input of the first amp. This higher ref. is reduced at the end of the charging process such that the leading edge of the output pulse of the second amp. coincides with that of the first amp.

Title: Cylindrical casing type rotary IC engine - has rotating discs in intersecting planes forming working spaces with varying volumes
Inventor: BAEHRING HORST
IPC: F01C3/06
Filed: 1976-03-02
Abstract: Engine has a cylindrical casing (11), and a rectangular plate (22) revolves on the axis of the cylinder dividing it into two halves. It carries two circular discs (33) at its ends which are perpendicular to it and to the cylinder axis and contain the inlet and discharge ports (12). A circular disc (44) is held across the cylinder at an angle to the cylinder axis. It can revolve in an inclined groove (6) in the cylinder wall and has a central slot through which the rectangular plate (22) passes. Rotation of the latter therefore causes rotation of the inclined disc in its guiding groove. The rotation of the plate and disc causes the spaces (7, 8, 9, 10) formed between them and the cylinder walls to vary in volume.
Patent DE-2619340-A1 (DE)
Title: Circuit board component attachment - has supported threaded spindle which drives element contacting stops to releasably hold components
Inventor: FUJITA TEIZO
IPC: H05K7/14

Title: Traversing yarn guide for synthetic yarn winding - comprises yarn carriers on twin belts running in opposite directions
Inventor: PFENNINGSBERG JOSEF
IPC: B65H54/28
Filed: 1976-05-19
Abstract: A winding machine having an arrangement for rotating the spindle on which the yarn package is to be wound, has a yarn guiding device arranged at right angles to the direction of approach of the thread. Device consitst of two endless belts arranged parallel to each other, and side by side in the same horizontal plane, as well as parallel to the axis of rotation of the yarn package spindle. The two belts run in opposite direction over guide rollers and on their outer surfaces there are at least two yarn carriers. At the reversal points of the traverse windings, inclined planes lift the yarn above the height of the carrier pegs. Constantly higher winding speeds are required in precision cross wound synthetic yarn packages having good dyeing characteristics, but the speed is restricted by the mass of conventional yarn guides. These limitations are overcome by the device described.

Title: Disinfectant spray system for milking machine - has milk flow meter connected to impulse transmitter which controls pump delivering to nozzles in teat cups
Inventor: TOLLE ADOLF PROF
IPC: A01J7/04
Filed: 1976-05-21
Abstract: The automatic disinfectant system for teats and milking machines consists of using a pressure difference to spray a certain quantity of disinfectant in the space surrounding the cow's teats (11), after milking has finished. The start of spraying the disinfectant is controlled by the intensity of the milk flow, which is measured on leaving the teat cup (7), thereby emitting a signal. The disinfectant is sprayed using a spontaneously built up underpressure. The milk flow is measured by a meter (13) in a short milk tube (6) joining the collector and the teat cup. The meter (13) is connected to an impulse transmitter (14) which controls a pump (16) with nozzles (18) fixed in the sides of the teat cup. The pump (16) has an electric drive mechanism (15) fixed to a container (21).

Title: Electronic and pneumatic control circuit for compressed gas - used for accurate dosing of molten metal from a casting furnace
Inventor: DOMRES HANS GEORG ING GRAD
IPC: B22D39/06
Filed: 1976-06-01
Abstract: Molten metal is fed in dosed amts. out of a casting furnace fitted with both an inlet and outlet-siphon, where compressed gas controls the does and also the level of the melt in the furnace during both casting and in the pauses between casting. The gas press. in the furnace, and the casting speed through the outlet siphon are continuously controlled during casting by adjusting the level of metal in the outlet channel via electric contacts and an electronic-pneumatic press. controller. After casting, a reference valve is used in the controller to keep the level below the outlet hole but above the max. level of the melt in the furnace; a second reference value produces a gradual increase in press. for the next dosing operation. The pref. appts. includes gas reservoirs; numerous valves; a servomotor driving controller; an optical meter measuring casting time; three sintered metal contacts coated with ZrO2 or Al2O3; and an electronic control circuit. Accurate dosing, using a simple control circuit may be achieved.

Title: Toxic load control of sewage plant - by measuring oxygen demand difference between standard and actual mixture
Inventor: BORMANN FRIEDER
IPC: C02F3/00
Filed: 1976-08-03
Abstract: Method is based on a comparison of the oxygen demand of a sewage sample and of a standard nutrient solution. The oxygen demand is measured in regular intervals on a first mixture of activated sludge, the standard nutrient solution and drinking water. In the second mixture, the drinking water is replaced by the sewage to be checked. Detected toxic substances can be by-passed into special tanks before they cause damage to the biogenic matter.

Title: Centering or rivet pegs mfr. from sheet metal - by cold flow forming using a hydraulic fluid
Inventor: ROSWANDOWITSCH HANS
IPC: B21D39/03
Filed: 1976-08-28
Abstract: Pegs are produced on metal sheet by cold flow forming using hydrostatic pressure. The length of the peg is determined by the measured vol. of a pressure medium located between a punch and the surface of the sheet; and the press. medium produces a blind hole in the sheet, the open end of the hole being adjacent to the punch. Pref. a press is fitted with a holding plate contg. a die on which the sheet is located by a holding-down plate contg. a punch with a conical recess. The edge of the cone forms a seal round the hydraulic fluid, which is pressed into the sheet to form the blind hole and the peg when the punch is lowered. Centering- or rivet- pegs of long length can be formed, esp. in sizes impossible to mfr. by conventional methods.

Title: HV cable for underground laying - consists of combined conductive metallic and non-metallic material with temp. coefft. compensation
Inventor: WOBST JOSEF
IPC: H01B1/00
Filed: 1976-09-25
Abstract: The underground voltage cable is formed by a combination of a metal and non-metal conductor. The combination compensates the resistance variations in that the non-metallic conductors reduce their resistance on heating, while the metal conductors in such condition show an increased resistance. This compensation removes the need for cooling. By the use of copper and graphite the different temp. coefficients and matching of conductor cross sections provides optimum conditions for widespread application.
