Title: Battery charger combining series and step regulation - with tapped transformer winding and thyristor rectifier giving high voltage step
Inventor: BECK ALFONS DIPL ING
IPC: H02J7/02
Filed: 1979-07-19
Abstract: The circuit provides two voltage levels for the unregulated dc supply without causing excessive ripple in the rectified voltage at the lower level. The secondary winding (2) of the rectifier transformer (1) has two sections. The main section (3) is connected to rectifier diodes (6), and provides the lower voltage supply to the series regulator (8,9) controlling the charging voltage of the battery. If the unregulated voltage falls below a set value, the higher voltage is switched in. The necessary measurement may be the voltage across the regulating transistor (8). The second stage comprises a thyristor rectifier (5) connected to the additional section (4) on the transformer secondary winding. The thyristor triggering can be controlled by the voltage detector (7). As the thyristors act only as switches, the output voltage ripple remains similar to that produced by the diode rectifier.

Title: Differential amplifier DC working point stabiliser - uses current-mirror circuit and gain-controlled amplifier
Inventor: RALL BERNHARD DIPL ING
IPC: H03F3/45
Filed: 1979-08-03
Abstract: The stabilising circuit has a current mirror circuit (23,24) connected at its input to the output of a gain-controlled amplifier (62) and containing two current sinks (23,24) acting as resistors for the first stage (71) of the two-stage differential amplifier (71,72). The output of the second stage (72) is connected to the input of the gain-controlled amplifier. The gain-controlled amplifier is a transistor whose collector is connected to the current mirror circuit and whose base and emitter receive control signals. The two outputs (A1,A2) of the second stage (72) are connected to resistors leading to the two inputs (E1,E2) of the first stage (71). The stabilising circuit is cheap and can be readily integrated.

Patent DE-3021059-A1 (DE)
Inventor: COVINI LORENZO
IPC: A63C7/10
Filed: 1980-06-04
Abstract: The brake consists of a single filiform element (20) shaped so as to form an "8" open at one end. This element comprises two end sections (23, 23') provided with hooked irons (27, 27') and two sections (24, 24') parallel with each other. These sections (23, 23', 24, 24') are connected by means of two intersecting and inclined sections which are inserted into channel-shaped seatings which are also slanting. The closed spiral, formed by the two parallel sections (24, 24') and a central section (25), is provided with a pressure plate (26). When the brake is in the inactive position, this plate (26) is pressed by the boot towards the ski, which elastically deforms the element (20) in the region of the intersecting sections. In the event of the boot coming out of the rear binding (10), the entire element (20) returns into its inclined position with respect to the ski, said element being made of a resilient material such as spring steel for example. <IMAGE>

Title: Distributor for lubricating grease of bearing - uses fresh grease to force old grease out of bearing minimising servicing
Inventor: RIENECKER LUDWIG
IPC: F16C35/04
Filed: 1980-07-16
Abstract: The distributor supplies the lubricating grease from outside the central axis of rotation of the bearing. The bearing may be for the wheel of a tracked vehicle motor. The grease is distributed over the bearing by a disc with outlet holes. The outlet holes (11) in the disc (6) increase in size in passing from the grease inlet hole (5') to a point on the diametrically opposite side of the disc. The area of the outlet holes on the diametrically opposite side of the disc to the inlet hole is 1.1 or 10 times the area of the outlet holes immediately adjacent to the inlet hole. The new grease forces the old grease out of the bearing completely and thereby considerably reduces maintenance work.

Title: Refrigerated sales display cabinet with horizontal bumper rail - has shock-absorbing corners of higher elasticity for greater impact
Inventor: FINKENAUER HARRY
IPC: A47B95/04
Filed: 1980-12-16
Abstract: The corners of the cabinet (1) are provided with shock-absorbing bumpers (4) which have a higher elasticity than the bumper rail (3) which is provided round the rest of the cabient to protect the latter from scratches caused by the shopping trolleys. The impact of knocks and bumps by trolleys is greater at corners than along the straight surface which is why the higher elasticity is required. The corner bumpers are pref. mounted with their ends beneath the bumper rail for an optically smooth transition between the rail and the corners.

Title: Method for producing a stabilised superconductor of the tube type
Inventor: SENDEROVIC PAVEL BORISOVIC
IPC: H01B12/00
Filed: 1981-05-27
Abstract: The method for producing a stabilised superconductor of the tube type having a superconductive layer based on an intermetallic compound, which layer is located on the inner surface of the superconductor, comprises the layer of stabilising material initially being removed from the end sections of tubular blanks (1) which contain at least one layer of stabilising material and one layer of that component of the intermetallic compound which has a high melting point (is refractory). A blocking layer, which prevents the formation of a superconductive layer, is applied onto the layer of the high-melting-point component on a part of the outer surface of the blank (1) from which the stabilising material has been removed. After this, holes (5) are produced on the end sections of the blanks (1), superconductive layers (9, 10) then being formed on the inner surface of the tubular blank (1) and on the walls of the holes (5), by heat treatment. The blocking layer is then removed, the blanks (1) are assembled and welded, and an additional superconductive layer (13) is formed on the outer surface of the connecting section of the blanks (1), which additional superconductive layer (13) connects the superconductive layers (9) located on the inner surface of the blanks (1) via the superconductive layers (10) on the walls of the holes (5). <IMAGE>
