Patent DE-2609331-A1 (DE)
Title: Motor driven valve for gas appliances - has reduction gearing driven by motor to open valve and spring bias for rapid closure
IPC: F16K31/04
Filed: 1976-03-06
Abstract: The motor driven valve for gas appliances has a closure member which is spring-biased into the closed position. A reduction gearing (18-30) enables the motor to open the valve slowly. The gearing is self-locking so that the spring bias cannot dominate the motor. The gearing can be locked against rotation by a latch (37) while the motor is de-energised. Release of the latch during the de-energised state of the motor enables the valve to close rapidly. The latch may be a pawl electromagnetically engageable with the gearing but biased into the withdrawn position.

Title: Sampling device for handling radioactive or toxic substances - with turntable revolving over feed needles to position vessels
Inventor: FINSTERWALDER LORENZ DIPL PHYS
IPC: G01N1/14
Filed: 1976-09-18
Abstract: A sampling device is used for transporting a sample vessel to one of a group of needle head filling units, in which the needles point vertically upwards, and also to a feed line and discharge line. The needle head filling units are mounted on a stationary frame beneath a turntable, which carries a sleeve to hold the sampling vessel; this sleeve can thus be travelled by rotating the turntable to the various needle heads and also to the feed and discharge lines. The turntable shaft also has a lifting device which raises and lowers the turntable independently of its rotational movements. The device is used in particular for sampling in the process control of nuclear fuel reprocessing. The escape of droplets of toxic or radioactive liq. is prevented. The vertical upward position of the needles ensures that the sample supplied into the sampling vessel contains little or no solids since these sink to the bottom of the needle unit. The entire apparatus may be mounted in a glove box for remote handling.

Abstract: The drive mechanism is for slatted curtains, where there is a transmission unit with the drive, the latter being connected to a drive wheel. It is designed to be as compact as possible. This is achieved by making the drive wheel (56) serve as a transmission housing for at least part (72,74) of the transmission unit. Where there are media for displacing or swivelling individual slats for opening and closing, a planetary gear with a hollow wheel (59) is used. The wheel is in the form of a drive wheel directly linked to the drive (65), which is coupled to the first movement unit (86). The planetary gear's sun wheel is then coupled to the second movement unit. Space is saved, whether the drive is manually or motor operated.
Patent DE-2700929-A1 (DE)
Inventor: BURKHALTER WALTER
IPC: F24F11/02
Filed: 1977-01-12
Abstract: A disc gear (1) of the device is firmly connected to a driver (2) arranged rotatably on a shaft (3). If the disc gear (1) is driven, for example to open a flap spring-loaded in the closing direction in an air-conditioning system, one end of a clutch spring (4) is taken along in rotation and the other end is initially held fast on the housing (5). As a result, the clutch spring (4) wraps more tightly around a drive feature (6). The latter is connected to the shaft (3) via a torsion return spring (7) and a hub (8). The shaft (3) is taken along in rotation as far as the opening stop of the flap, the torsion return spring (7) being increasingly tightened in the process. If there is a drop or failure of the torque exerted by a motor on the disc gear (1), the torsion return spring (7) relaxes. In the process, it drives the drive feature (6), the clutch spring (4) thereby being turned in the opening direction and unwrapped. The clutch is released and the damper is snapped shut by a further spring. The device permits abrupt, automatic decoupling without the use of extraneous energy. <IMAGE>
