Title: Indexing scraper conveyor for removing machine waste - has reciprocating plates on support tilted and slid along axis by crank drive
Inventor: BAER ALFONS
IPC: B65G25/12
Filed: 1977-10-29
Abstract: The indexing conveyor has reciprocating scraper plates at intervals shorter than its stroke, at the end of which they are lifted clear on the floor for the return movement. The plates (4) are rigidly mounted on a support (5), tilting on and sliding along an axis parallel to the transport direction. The plates are actuated by a crank mechanism controlling their movement so that in this direction they slide along the floor (2), and in the reverse direction are swung up clear of it. There can be a crank to the side of the conveyor with an elongated hole, in which a dog fixed to the scraper assembly engages.

Title: Single element imprinting assembly - has kinematically independent controls for character selection and imprinting movements of printing element
Inventor: LEE KUOLIANG
IPC: B41J7/50
Filed: 1977-12-31
Abstract: The single element imprinting assembly of the disc, cylindrical or spherical type for use in typewriters has a stationary printing assembly having kinematically independent controls for character selection and imprinting movements of the printing element. The stationary printing assembly arrangements avoids the penalty of added moving mass when the mass of the character selection prime mover is increased. For the cylindrical and spherical types, the independent movement is achieved by three separate drive controls such that the axis of the tilt or control and the axis of the rotational drive control both perpendicularly intersect the axis of the imprinting drive control at separate points with universal joints or other constant speed couplings being located at each respective intersection allowing independent and concurrent rotation.

Title: Telephone charge meter with display - feeds two numbers into calculator and produces quotient which is added to displayed sum
Inventor: STEIGER WOLFGANG DIPL ING
IPC: H04M15/30
Filed: 1978-01-25
Abstract: The meter has a keyboard with figures 0 to 9, and a calculator combined with a signal generator delivering timing control signals at fixed time intervals.

A coding circuit may be used to insert a tariff rate (e.g. for a telephone call charge) to set the counting system to give signals at the correct times. The programme logic unit is connected to a floating-fixed point decoder.

Title: Water filter with basket backflush mechanism - having conical filter basket with backflush channel attached to axial shaft down centre of filter which is moved up to flush element
Inventor: SEIFFERT GUENTHER
IPC: B01D29/11
Filed: 1978-12-05
Abstract: Filter with back flush mechanism has element in the form of a conical basket. At one side is a rim of channel with the same profile as the basket, attached to a shaft running down the centre of the filter. This shaft has a pair of valve elements at its base and has a screw thread at the top. When rotated the shaft moves up or down. When the shaft is raised, the lower valve opens allowing liq. to escape and draws liq. down the backflush channel. When fully retracted, the second valve element seals the run off from the dirty liq. side of the filter and only allows out the liq. which runs down the channel. The channel fits flush onto the element and pulls liq. back through, all the surface being cleaned by rotating it round. Used for filtering liqs. esp. water. Arrangement gives improved operational efficiency with economic construction and functional design.

Abstract: The load-hoisting mechanism has a load hook raised and lowered in a housing. The hook (5) swings away from its opening about a horizontal spindle (9) and in a member set down and supported on the load to be lifted. The spindle, with the hook and the member (4), moves up and down for a limited amount in the housing (3). in the latter are a thrust bolt (8) and lever (6) forming a deflector mechanism working with the hook, also a locking mechanism (11-23) securing the member to the housing for each lift.
Patent DE-2911236-A1 (DE)
Title: Vacuum cleaner with hose connector branch - has spring-biased member to reduce sectional area when hose is removed
Inventor: DIEBOLD MAX
IPC: A47L9/24
Filed: 1979-03-22
Abstract: The hose connecting branch (2) contains at least one member, e.g. spring-controlled flap (10) which reduces the corss-sectional area of the branch and can be moved when required to widen the cross-sectional area, at least partly. The flap can be designed, e.g. to swivel about an axis which lies at right angles to the axial direction (11) of the branch. In this way, when the hose or other adaptor is not used, the cross-section can be reduced to throttle the air flow to avoid overheating. When the hose is inserted, the cross-sectional area is suitably widened by the hose movement overcoming the spring force.
Patent DE-2913928-A1 (DE)
Title: Milking appts. with built-in cleansing system - has simpler control valve with floating closing body suitable for any sized pipe
Inventor: SCHLETTER PETER
Filed: 1979-04-06
Abstract: The control valve (10) provided in the suction pipe section between the milking point and the flushing agent container (2) is designed as a floating valve with two suction pipes (11,12) mounted in the flushing agent container (2) for the air intake and the flushing agent intake. The open end of the air intake pipe (11) serves as the sealing seat (13) for a valve closing body (14) which floats up towards the seat. The seat (13) is set on the air intake pipe (11) higher by a predetermined amount than the open end of the flushing agent intake pipe (12). Thus when cleaning the milking machine the flushing agent is drawn in from the supply container with the air intake pipe closed until the level of flushing agent drops below the level of the valve seat and the valve closing body drops.

Title: Positioning system for tool carriage w.r.t. moving workpiece - allows cutting etc. or continuously moving workpieces, using sensor and evaluator controlling start and return springs
Inventor: PIASTA VOLKER DIPL ING
IPC: B26D5/24
Filed: 1979-11-01
Abstract: The positioning system holds the carriage (1) in its rest position against the action of a start spring (5). When released, the start spring accelerates the carriage in the direction in which the workpiece is moving linearly through the machine. A sensor measures the movements of the carriage and the workpiece (14). Signals describing these movements are compared and the result used to position the carriage using an electronic evaluator when the carriage and workpiece are moving at the same speed. The start spring can be set so as to impart different accelerations to the carriage. A return spring (19) forces the carriage to its start position along with the workpiece.
Patent DE-2945017-A1 (DE)
Title: Coke oven door - with hollow stopper as gas collecting space for improved gas and coke quality
Inventor: BREIDENBACH DIETER DR
IPC: C10B25/06
Filed: 1979-11-08
Abstract: Door for a coke oven of the horizontal chamber type is fitted with a box-shaped stopper which enters the chamber and keeps the coal charge at a distance from the door to act as a heat protection. The hollow stopper also serves as a gas collecting space because it has no end plates at the bottom or the top. The stopper is made of several rectangular boxy sections with expansion gaps between the sections which are overlapped at the sides facing the coal charge by welded angle iron strips. This improves the gas extraction and the life of the coke oven doors. The coke cake becomes more homogeneous and overheating of the top parts of chamber and door is prevented.

Title: Ice cream mixing and dispensing machine - with slotted discharge piston revolving with mixer-scraper blades
Inventor: ZOPPELLARI CARLO
IPC: A23G9/12
Filed: 1980-02-04
Abstract: Machine for intermittent mixing and dispensing of pasty food, esp. ice cream, consists of a refrigerated horizontal cylinder in which two spiral scraper/mixer blades can be rotated. A piston has inclined slots through which the blades pass. A ball bearing allows the piston to revolve with the blades. The piston rod finally moves the piston to dispense the ice cream. Ice cream can thus be fully discharged from the machine and the operation can be carried out at the optimum temp.
