Patent DE-2852847-A1 (DE)
Title: Automatic loading of tape cassette spools onto magazine pins - orientating spools into position and loading onto pins by double-acting cylinder load unit
Inventor: BREUER RUDOLF
IPC: G11B23/113
Filed: 1978-12-07
Abstract: An automatic handling system loads magnetic tape cassette spools onto magazine pins on a rotary table ready for insertion into the cassette housings. The cassette spools are fed in sequence along a guide track. A friction wheel driven by a belt causes the spool to be rotated until the correct orientation is achieved by a stop locating in the section of spool where tape is initially attached. The rotation also causes a pivoted lever to operate a switch and this activates a valve to power a double-acting pneumatic cylinder. The cylinder moves vertically to push the spool onto a magazine pin on a turntable. The process repeats until the magazine pin is full and the table then indexes. Air is used to blow the spools along the guide track.

Title: Reliable limit switch for indicating and recording instruments - has indicator proximity detector working with adjustable strip
Inventor: KOCH PETER HELMUT
IPC: G01D15/00
Filed: 1979-06-25
Abstract: A limit switch for an indicating and/or recording instrument has a proximity initiator head connected to the indicator and a trigger element acting on the head and which is adjustable along the path of motion of the head. It is a very simple arrangement whose initiator reliably produces no spurious signals. The initiator signal remains correctly associated with further boundary related indicator positions even when the switch over does not take place cleanly. The trigger element is a strip of material along the movement path arranged so that the head gives different signals for different distances. The position along the strip at which the strip-to-head distance changes is set by a deflection head.

Title: Brushgear for radial face slip-rings on motor vehicle generator - is mounted in caliper fashion to give equal brush pressure on both rings
Inventor: HAGENLOCHER WALTER
IPC: H01R39/10
Filed: 1979-06-29
Abstract: The slip-ring units comprises two rings (15), axially in line, with radial contact surfaces facing in opposite directions. The rings are typically mounted on a disc and bush (14,13) of insulation material which fits on the end of the generator shaft (11). The brushes (18) run on the radial faces. They are mounted on a caliper type holder having carrying arms (19) of equal length and a spring (21) in tension giving the required brush pressure. The arrangement gives equal pressure between both brushes and their respective slip-rings. The radial face contact eliminates any effects of shaft eccentricity. Both these features combine to give smooth running and long brush life.

Patent DE-2935269-A1 (DE)
Title: IC engine pressure-charging system - generates vacuum by ejector in exhaust to deliver fresh air to engine
Inventor: OBERLEITNER JOHANN DIPL ING
IPC: F02B37/00
Filed: 1979-08-31
Abstract: The combustion air pressure-charging system is for use with diesel and otto-cycle engines. The hot exhaust gas from the engine is used in an ejector, in order to draw air in, generating a vacuum which is subjected to pulsation, causing fresh air to be delivered into the engine. Intensive mixing of the exhaust gas used for the ejector jet with air causes further reaction of the ingredients in the exhausts which are capable of it, thus reducing pollutants. Expansion of the exhaust/air mi mixture in the ejector diffuser causes it to be discharged at nearly atmospheric pressure. This reduces engine noise and allows a simpler design of exhaust silencer.

Title: Two=stroke rotary IC engine - includes piston seals with three packing strips to reduce leakage
Inventor: WAGNER ALBERT
IPC: F02B75/02

Abstract: The engine has two rotary pistons (2,3) axially adjacent to each other on a common shaft. They have radially projecting lugs which extend axially beyond the pistons so that the lugs on the two pistons face each other and form working spaces which vary in volume as the pistons rotate at different speeds. The periphery of each lug has grooves in each of which there are three cylindrical plugs (22). Each plug has a recess which accommodates a sealing strip (20). In each seal formed in this way two of the strips (20) are angled and one is straight. This ensures both axial and radial sealing.
