Title: Lifting jack for lifting and supporting heavy loads
Inventor: VEMMER REINER DIPL ING
IPC: B66F9/06
Filed: 1993-03-25
Abstract: The lifting jack for lifting and supporting heavy loads has a jack frame (4) which is carried by a chassis (1) with four running wheels (2, 3) and can be lowered relative to the chassis (1) into a standing position and lifted into a travelling position. Cantilevers - claws - (6) accepting the load are mounted so as to be vertically movable with a slide (5) in the jack frame (4) and so as to be extendable in the slide (5) transversely to the vertical movement for accepting the load. This chassis (1) is designed as a spring-power chassis and carries the jack frame (4) in a liftable and lowerable manner relative to the travel plane (9) with springs (7, 8) inbetween. The running wheels (2, 3) of the chassis (1) arranged on the load-acceptance side are set back relative to the load-acceptance end (6a) of the extended cantilevers (6), and the chassis (1), during loading of the jack frame (4) and when the jack frame is lowered, maintains ground contact with the travel plane (9) with all running wheels (2, 3), and the entire lifting jack is always vertical. <IMAGE>

Title: Explosion-proof microswitch component
Inventor: KAPFER KARL
IPC: H02G3/08
Filed: 1993-04-20
Abstract: An explosion-proof microswitch component has a switch housing (10) into which a switch (16) is inserted. In order to fix this switch before encapsulation (potting), a closure part (31) is provided which is latched to the switch housing and then fixes the switch via legs (21.1, 21.2). The switch is then encapsulated. In the case of a first embodiment, the closure part is designed as a base part with an opening through which a connecting cable runs in a relatively tightly seated manner. Said cable is positioned with relatively tight tolerances with respect to the switch housing. In the case of a second embodiment, the closure part is designed as a terminal holder (31) on which a terminal housing (30) is mounted with the aid of a captive bracket (35). As a result of this design it was for the first time possible to produce an explosion-proof microswitch component with a terminal box. <IMAGE>

Title: Pivot bearing, in particular for a folding table
IPC: A47B13/00
Filed: 1993-06-30
Abstract: In the case of the joint parts which are connected to one another in articulated fashion and are pivotable relative to one another about an articulation axis, at least one bearing web extends away from one joint part at right angles to the articulation axis, the bearing web being penetrated by a bearing recess and having a deformation zone effective transversely to the superficial extent of the bearing web. The other joint part possesses a projecting bearing journal, onto which the bearing web is clipped by its bearing recess under at least partial elastic deformation and is axially arrested in this mounting position. According to one embodiment, an abutment on the other joint part, which grips over an end portion of the bearing web projecting beyond the bearing recess, serves for the axial arresting of the bearing web in the mounting position. The abutment may also be furnished with an oblique face which rises approximately from the articulation axis and, during the mounting, elastically deforms the end portion of the bearing web in the direction of the bearing journal until the latter is clipped by its bearing recess onto the projecting bearing journal.

Title: Switched-mode power supply device having a snubber circuit
Inventor: MOTONOBU MASAHIRO
IPC: H02M3/335
Filed: 1994-06-17
Abstract: A switched-mode power supply device is described, in which the primary winding (7a) of a transformer (7) can be cyclically connected to and disconnected from a dc source (1) via a first (2) and a second (3) transistor. A snubber circuit prevents an overvoltage occurring across the transistors when they are turned off. The snubber circuit comprises, in parallel with the first transistor (2), a first series connection of a first capacitance (15, 19) and a first diode (13), and, in parallel with the second transistor (3), a second series connection of a second capacitance (16, 20) and a second diode (14), as well as a third series connection, which contains an auxiliary winding (7c) of the transformer (7), an inductor (18) and a third diode (17) between the junction point of the capacitance (15, 19) and the diode (13) of the first series connection and the junction point of the capacitance (16, 20) and the diode (14) of the second series connection. The counter-EMF which is induced in the primary winding when the transistors are turned off is stored in the capacitances. When the transistors are turned on, the auxiliary winding (7c) generates an additional voltage which is added to the charging voltage of the capacitances. This means that the capacitances are discharged during the turn-off duration and in the subsequent turn-on operation, and the previously stored energy is fed back to the current source. <IMAGE>

Title: Superconductive solid body device
Inventor: SIZMANN RICHARD DR
IPC: H01L39/12
Filed: 1994-06-21
Abstract: The device includes at least two layers (1,2) of different electrical conducting materials. Charge carriers (6) from one layer (1) cause charge carrier pairs (8) of identical charges in the energetic basic state of at least one other type layer (2) using polarisation (7). The charge carrier pairs change into a superconductive state below a function temp. Pref. the polarisation in the second layer represents at least partial resetting of the charge carriers in at least one unfilled energy band. The band edge extension of the layer sequence may be such as to provide potential wells and barriers for the charge carriers in the respective layers. The formation of carrier pairs or the function temp. may be influenced by the irradiation of the device with photons.

Title: Humidity sensor for heated front or rear window of vehicle
Inventor: EGGER ARMIN
IPC: G01N27/02
Filed: 1994-07-28
Abstract: A humidity sensor for controlling the windscreen wipers of the heated front or rear window of a motor vehicle operates by measuring changes in the capacitive component of impedance of the heater matrix already present in the vehicle window. A microcomputer (10) controlling an oscillator (11) applies a HF voltage via the coupling capacitor (15) to the parallel LC oscillatory circuit formed by the capacitor (9) and heater matrix (3). A resonant condition is generated and registered by the computer (10) and the presence of water vapour materially affects the capacitive reactance of the system, so detuning away from resonance for wiper action control via the computer (10).
