Title: Disinfectant metering system - with metering pump controlled by timing pulse generator and actuated by water delivery pressure
Inventor: WIENHOLD WILLY
IPC: A61L2/24
Filed: 1979-04-19
Abstract: A system for a metered admixture of a disinfectant to tap water for use in swimming baths and hospitals has the zero pressure admixture tank arranged between the intermediate water vessel and the main pump. A solenoid valve in the tap water supply line is controlled by a min. and max. level pickup in the admixture tank. The metering pump is controlled by a timing pulse generator during the open periods of the solenoid valve; this actuates another solenoid valve and admits water from the delivery of the main pump to drive the metering pump. This ensures a perfect mixt. of disinfectant and water and prevents the delivery of plugs of disinfectant separated by plugs of water. The metering rate is easy to adjust and to check.

Title: Piezoelectric microphone housing in telephone subscriber's handset - guards against demodulated pick-up of radio waves by single 10 nano Farad capacitor across amplifier
Inventor: SCHIERL HANS
IPC: H04R1/04
Filed: 1980-06-27
Abstract: To eliminate from the output of a piezoelectric microphone amplifier the effect of the spurious influx of rectified electro-magnetic waves picked up by the power supply lines and demodulated by the diodes (G1 to G4) which are required to secure against the faulty poling of d.c. voltages, the arrangement provides a metallised layer in the microphone housing which serves as a screen (S) and a single 10nF capacitor across the power supply terminal of the amplifier circuit (V). The negative pole is connected to the screen as well. The effect of this measure is that the cross-talk effect is reduced by about two orders of magnitude.

Patent DE-3043334-A1 (DE)
IPC: E05D7/12
Filed: 1980-11-17
Abstract: The mounting plate has a track for slidably guiding the hinge bracket in an axial direction and a bore for longitudinally slidably guiding a spring-loaded detent pin, which protrudes from the bore and is held captive therein by at least one stop in the surface defining the bore. The hinge bracket has a sloping surface, which is arranged to force the detent pin into the bore as the hinge bracket is slidably moved onto the mounting plate. The hinge bracket also has a surface which as the hinge bracket is pushed over the detent pin holds the latter in a depressed position until the detent pin snaps into a detent opening of the hinge bracket so that the latter is releasably fixed. A locking mechanism of the type used in retractable ball point pens is provided and is adapted to lock the detent pin in two different (partly extended and fully extended) positions. The pin is adapted to be moved from one of said positions to the other in that the detent pin is depressed into the bore and then released. The free end of the detent pin lies in the path of the sloping surface when the detent pin is in its partly extended position. The pin which has been depressed by the sloping surface is adapted to snap into the detent opening and to be urged in said detent opening by the spring toward its fully extended position.

Title: Drive chain for a variable transmission
Inventor: STEPHANOFF LOUIS JOHN
IPC: F16H9/24
Filed: 1981-03-05
Abstract: The invention proposes a drive chain for a variable transmission, in which the drive chain (10; 100; 200) engages in tapered inner sides (45c) of transmission pulleys (36). Drive pins (32; 232), which are pushed through links (12a, 12b, 12c, 12d, 12e; 14a, 14b, 14c, 14d; 212a, 212b, 212c, 212d; 214a, 214b, 214c, 214d) of the drive chain (10; 100; 200) each extend along a central longitudinal axis (C) situated at a distance from a pitch circle (P) extending between the pivot joints of the drive chain (10; 100; 200), thereby resisting a moment of force which would cause twisting of the links relative to one another at the pivot joints. Pivot pins (16; 216) are accommodated with a loose fit in the links in order to allow axial and rotary motion relative to the latter. Retaining washers (34) are mounted on the ends of the drive pins (32) at a distance from the relevant links in order to limit the axial motion of the drive pins (32) relative to the links. In general terms, the links are triangular in shape. The drive pins (32; 232) are preferably significantly larger in diameter than the pivot pins (16; 216). The drive pins (32; 232) lie in an endless driving loop (D) which extends either outside or inside the endless pitch circle (P). <IMAGE>
