Title: Mobile camera esp. for inspection of cavities or pipelines - has hemispherical rotary carrier of objective lens with belt drive for variation of focus and aperture
Inventor: KELLER GUENTER
IPC: G02B23/24
Filed: 1992-09-18

Title: Ballast circuit for fluorescent lamp - uses two transformers with filament heating windings in phase opposition and time switch for ignition winding
Inventor: BOHNE RONALD
IPC: H05B41/295
Filed: 1992-09-28
Abstract: The ballast uses a transformer (2) connected to the power supply (1) with three secondary windings in series, there being a condenser (C1) between the middle winding (2.2) and one end winding (4.2). The middle winding gives the ignition voltage, the end windings give the filament heating voltage. These two end windings are connected to the secondary windings of a second transformer (4) so as to have a different phase relationship from that in the first transformer. A time switch (3) connects the primary winding of the second transformer (3.4) to the middle secondary of the first transformer. The impedance of the primary winding of the second transformer is much smaller than that of the middle winding of the first transformer. ADVANTAGE - Higher reliability and lamp efficiency with longer lamp life.

Title: Pressure-controlled valve for industrial vehicle - has three valve chambers separated by air-tight seal and barrier, and compact housing
Inventor: GEIGER WINFRIED DIPL ING
IPC: B60G17/052
Filed: 1992-10-14
Abstract: The valve has three connections (30-32) corresp. to three valve chambers (27-29) in a housing (10). Two chambers (27,28) are sepd. from each other by a barrier (13) which is pressed onto a valve seat (12). A second valve seat (23) is connected to the barrier. The axial bore of the valve is compact but large enough to allow the required air flow. The barrier (13) is in fluid-tight connection with the two valve seats via a ring-shaped elastomer seal (25) placed in the ring nut (26) of the barrier. A pressure source is connected to one valve connection (32), and a pressure sink is connected to a second valve connection (30). ADVANTAGE - Compact construction, flexible use.

Title: Concentration of washing suds - uses heated tank contg. suds, creating fine air bubbles at base, extracting volatiles at top and concentrated suds at base
IPC: D06F39/00
Filed: 1992-11-27
Abstract: A process for concentrating suds contg. solids, esp. washing suds involves: i) heating the suds in a container (2); ii) introducing gas, esp. air into the lower area (3) of the container; iii) creating fine air bubbles which rise through the suds; iv) extracting volatile from the upper area of the container (2) and concentrated suds at the base. Suds are stirred during processing while air is centrally introduced (10) to form an air cushion under a rotating perforated plate (7). After flowing through the perforations, the fine air bubbles rise through the suds. Carrier gas is recycled in a closed circuit after removal of volatiles by condensation. USE/ADVANTAGE  - Concentrating suds containing solids, esp. washing suds in large launderies. Higher suds concentration than in ultrafiltration equipment.

At least one of the light-sensitive costs contains a phenolic cyan coupler with a ballasted acylamino gp. in the 2-position and ethyl gp. in the 5-position; and at least one contains a pivaloylacetanilide yellow coupler. USE/ADVANTAGE - The material is esp. suitable for colour negative and reversal films and paper. The use of a chain (L) of only C or C and O atoms between the chromophore (pyrazolotriazole) gp. and hydroquinone stabiliser gp. increases the light fastness of the dyestuff.
Patent DE-4240871-A1 (DE)
Title: Compressor operating on fluid piston principle - uses fluid medium to close one side of working chamber
IPC: F04C19/00
Filed: 1992-12-04
Abstract: The compressor or working engine incorporates closed working chambers which are used for the performance of work. The working chambers are closed on one side by a fluid medium. On moving the medium the working chambers are reduced and enlarged in capacity such that the compression and decompression of a gas takes place. The fluid medium is designated a `fluid piston' and the machine consists of a stator housing (1), rotor (3) on a hollow shaft (5) and fluid piston boundary surfaces (11). USE/ADVANTAGE - Compressor operating on fluid piston principle combines the advantages of a piston engine and a turbine but avoids the disadvantages of the two systems.
Patent DE-4242019-A1 (DE)
Title: Yawing moment compensation system when braking - has steering gear coupled to track rod solely via pressure- accumulators whose volume alteration causes track-rod movement in opposition to them
Inventor: AMMON DIETER DR ING
IPC: B62D6/00
Filed: 1992-12-12
Abstract: The wheels in a steered pair have independently-operating anti-locking devices, difference in brake pressures causing steering adjustment in opposition to the effect of the moment. The brake pressure in each anti-locking device is fed to a pressure chamber (11) in an adjusting unit (10), the chamber being of variable volume and a wall separates the two chambers. Increase in the volume of one chamber reduces that or the other and is converted into a steering movement. The steering gear (31) is coupled to the track rod (32) solely via pressure-accumulators (13). Alteration in the volume of a chamber (11) causes movement of the track rod in relation to the steering gear in opposition to the effect of the accumulators. Each chamber can consist of a cylinder with a piston (15) working in it, this being at the end furthest from the dividing wall. A rigid coupling member (16) between the pistons holds them at a set distance apart. ADVANTAGE - Complete counteraction of yawing moment without transmitting forces to the steering column or wheel.

Patent DE-4331272-A1 (DE)
Title: Control valve for the forced cooling of pressure medium-operated friction disc brakes and/or clutches in motor vehicles
Inventor: GROEGER GUENTHER
IPC: F16D65/853
Filed: 1993-09-15
Abstract: In known control valves the valve spool is acted upon by a return force which is generated by a compression spring. The existence of the compression spring, however, involves a certain manufacturing and assembly cost and has an unfavourable influence on the brake operating performance. A reduction of the said cost and an improvement of the brake operating performance is achieved in that the valve spool (19) is acted upon by the pressure of the coolant for generating the return force. <IMAGE>

Patent DE-4337254-A1 (DE)
Inventor: HEINDORF HELMUT DIPL ING
IPC: H01H71/02
Filed: 1993-11-02
Abstract: In what is known as a current-operated earth-leakage circuit breaker with overcurrent release, configured in a modular serial design, the leakage current module with its housing (1) is aligned laterally to circuit breakers and connected to them to form a compact modular unit. This involves establishing a connection between a summation current transformer of the leakage current module and terminals of the circuit breakers as well as coupling their switching and tripping mechanisms. The external electrical connection is effected at each leakage current module by means of terminals arranged within a terminal space (3.1) of the housing (1). To be able to allocate this leakage current module connection to either the upper or the lower connection level of the switch in accordance with the local conditions, the housing (1) of the leakage current module can be assembled with an interlocking fit between a multipart central body (2) and, situated on either side thereof, two side bodies (3, 4) extending over the full width of the housing. The two side bodies (3, 4) have different designs, the larger side body (3) comprising the terminal space (3.1). As needed, the two side bodies (3, 4) can be alternately joined to the central body (2) with its symmetrical housing contours (2.5) to form a finished housing (1) for all the components of the leakage current module. The leakage current module can thus be combined universally with circuit breakers to form current-operated earth-leakage circuit breakers with overcurrent relase, of varying rated current.
