IPC: H02H7/08
Filed: 1979-06-15
Abstract: The exciter is electrically coupled to the excitation coil of the synchronous machine, a starting block with at least one branch being in parallel to the exciter. The branch (6') is formed by a series-connection of a resistor and a thyristor switch. It has a control circuit with a threshold value element with a voltage dependent response. The current supply has a time delayed commutator. In the starting block (6) branch is incorporated a series fuse (11), and a protective thyristor (12) is in parallel to the starting block. This thyristor is energised by a control element (13) coupled to the thyristor control electrode via the commutator (14). The resistor (7) of the starting block forms pref. the control element of the protective thyristor. If two adjacent starting block branches are used, their fuses may be interconnected across a de-excitation contactor.

Title: Fluid quantity indicator esp. for aviation fuel - uses capacitive sensing probes with capacity change proportional to amount of fluid in tank or container
Inventor: HEDRICK GEOFFREY S
IPC: G01F23/26
Filed: 1979-09-07
Abstract: The improved fluid quantity indicator, such as for aviation fuel, is of the type utilising capacitive type sensing probes in which capacitance change occurs proportional to the amount of fluid in a tank or container due to the dielectric constant of the fluid being different from that of air. Microprocessor control provides display and totalising control in conjunction with automatic compensation for the zero fluid capacitance variation in a tank and automatic adjustment of the fluid full scale reading for variation in fluid tank capacitance. The microprocessor controls two independent digital servo loops.

Title: Cyclic cleaning of air filter hoses - where clean compressed air is periodically blown into each hose to remove filtered dust on outside of hoses
Inventor: OETIKER HANS ING
IPC: B01D46/44
Filed: 1979-02-19
Abstract: Industrial air filter contains several filter hoses suspended vertically in a chamber. Air contaminated with dust or chemicals flows into the chamber and through the hoses to a top exit chamber for clean air, so dust etc. collects on the outside of the hoses. In the top exit chamber is a drum (207) employed for the periodic feeding of compressed air to the inside of the hoses so the dust is blown off the outside of the hoses into a sump. In the wall of drum (207) are pairs of holes (213, 214); and each pair can be connected together via a hole (193) in a rotor (192). Each end of the rotor (192) is fitted with a magnet; and the drum is surrounded by magnet yokes (197) so it functions as a stepper motor controlled by an electronic circuit. Compressed air can be successively fed through all the hoses, so the latter can be cleaned one at a time without interrupting air filtration.

Title: X=ray microfilming unit with controlled daylight shield - operated to block ambient light only during film exposure
Inventor: ROSS EBERHARD DR MED
IPC: G03B27/32
Filed: 1980-02-05
Abstract: The unit has a worktable surface the rear thid of which is enclosed by a light-shield housing which fits over the vertical support for the microfilm camera, leaving the remainder of the surface fully accessible. A U-shaped shield is selectively pivoted across the access opening at the bottom front of the light- shield housing, to block ingress of ambient light during actual filming. Pref. the movement of this shield is effected using an electric motor and an eccentric cam disc, or pneumatically, hydraulically or megnetically, in synchronism with the actuation of the exposure switch. A red transparent foil may be positioned across the front of the shield to allow the operator to view the filming process.

Title: Water dispenser with release cone - has multi-angled wire forming press button to prevent contamination of water
Inventor: SCHWARZ ULRICH
IPC: A47G33/02
Filed: 1980-02-11
Abstract: The dispenser is esp. for holy water in a church. It is operated by a press-button nozzle in which the water is released by raising a cone (6). A wire hoop (8-11) raises the cone. It is fixed from below into the bore (7) of the opening of the cone (6). Then wire projects down from the bore (7) first in the direction of the bore (7) then at an acute angle sideways and upwards where it then runs straight down finishing in a horizontal contact member (11) and an angled short end piece (8). This design prevents the transmission of diseases from the finger button wire to the holy water in the container.

Title: Pressure actuated lighting time switch - has pushbutton which is arranged about rotary latching or setting ring with relative angular movement
Inventor: SCHMID ROLF
IPC: H01H13/54
Filed: 1980-02-16
Abstract: The time switch is arranged so that depression of the push-button evacuates an air-filled chamber against a resetting force. The refilling of this chamber takes place automatically via a valve during a pre-determined, preferably adjustable, time period, thus re-releasing the push-button (2). Round the latter is rotatably fitted a locking or setting ring (4), which is axially fixed, but can be rotated through a given angle relative to the push-button in a blocking position holding down the depressed push-button. The push-button and the setting ring respectively have a radially protruding lug and an L-shaped groove, which interengage. The 'L'-shank of the groove, extending in the depression direction, releases the lug after a given time period. The transverse shank of the 'L' lies over the depressed lug in the locking position of the ring. The groove(s) may be located on the ring inner side, while the lug(s) may be provided on the push-button.

Title: Coated metal components, esp. terminals for electronics - coated esp. with tin solder by magnetic wheel which conveys components through coating liq. bath
Inventor: BEHRENDT ERNST-GEORG
IPC: B65G49/04
Filed: 1980-07-17
Abstract: Surfaces of small metal components, esp. terminals, spade terminals etc. used in electronic equipment, are coated with liquid, more specifically tin solder. The components are fed onto the perimeter of a magnetised wheel, revolving about a horizontal shaft; as the wheel revolves the components dip into the liq. bath, after which they are removed from the surface of the wheel by a separator. The magnetic regions of the wheel are pref. coated with "TEFLON" (RTM). The magnetic zones may be in the form of rings around the wheel, parallel to each other and spaced axially apart. The components are pref. fed onto the wheel from a feed chute, oscillated transversely across the wheel surface by a drive mechanism so as to distribute the components over this surface. The system of feeding, transporting and subsequently removing the components is extremely simple.

Title: Drawbar for close coupled trailer - has steering control bar offset from towing axis to steer trailer front axle
Inventor: GOERGE WERNER DR ING
IPC: B62D13/04
Filed: 1980-08-09
Abstract: The close coupled trailer drawbar has a steering control rod (4) linking the trailer and towing unit, in the same horizontal plane as the drawbar but offset to one side of the unit. The rod is displaced when the trailer and unit are angled for cornering, with the rear end of the rod operating a steering linkage to steer the front axle wheels (3) of the trailer. The trailer is able to track in tight curves without angling the body too tightly with that of the towing unit. This increases the load space of the trailer. The steering rod is hinged on a control lever to pivot about the transverse pivot (6) of the drawbar.

Title: Vehicle speed measurement and display without power network - uses permanent magnets on wheels with chassis mounted coils
Inventor: LINN KARL-OTTO DIPL ING
IPC: G01P3/487
Filed: 1980-09-12
Abstract: The measurement and indication device for use in vehicles without a built-in electrical system has no moving parts and hence no frictional losses and very low braking effect. It enables the vehicle speed to be displayed as accurately as required without needing external power from a battery or dynamo. One or more permanent magnets (2) are attached to one or more wheels (1) with associated pick-ups (3) on the vehicle. When the magnets pass the pick-ups they generate electrical signals which pass to a rectifier (4) and to an evaluation circuit. Coils are used as pick-up devices and they drive a counter (7) with a memory (8) and display (9). A smoothing capacitor (5) and zener diode (6) are connected to the output of the rectifier (4).
