Title: AC voltage stabiliser
Inventor: BROECK HEINZ VAN DER DR ING
IPC: H02M5/458
Filed: 1987-01-30
Abstract: The invention relates to an AC voltage stabiliser, in which the mains current is impressed via a two-point current regulator (22) with the aid of a first four-quadrant controller (6) having a first invertor branch (7, 11, 8, 12) and a second invertor branch (9, 13, 10, 14), and in the case of which the capacitor current of the output filter (26, 25) is impressed via a further two-point regulator (37) with the aid of a second four-quadrant controller (6') having a first invertor branch (9, 13, 10, 14) and a second invertor branch (29, 31, 30, 32). In this case, the first four-quadrant controller (6) and the second four-quadrant controller (6') have a common invertor branch (9, 13, 10, 14). This common invertor branch (9, 13, 10, 14) is driven at a frequency which is identical to the mains frequency (fN). The mains current is adjusted by the first invertor branch (7, 11, 8, 12) of the first four-quadrant controller (6), by means of unipolar pulses. The respective state of the common invertor branch (9, 13, 10, 14) in this case defines the adjustment range of the voltage between the first invertor branch (7, 11, 8, 12) of the first four-quadrant controller (6) and the common invertor branch (9, 13, 10, 14). (Zero-positive intermediate-circuit voltage or zero-negative intermediate-circuit voltage). The output voltage is adjusted indirectly via the adjustment of the capacitor current (IC) in the output filter (26, 25)... Original abstract incomplete. <IMAGE>

Patent DE-3716766-A1 (DE)
Inventor: LAURENT MICHEL
IPC: C03C27/12
Filed: 1987-05-19
Abstract: A glazing panel suitable for use as part of an alarm system comprises at least two sheets of glass 2, 4 bonded together into a laminate by intervening adhesive material 5. At least one glass sheet bears an electrically conductive coating 3 extending between at least two electrodes such as 8. Surface layers of at least two of the glass sheets are unequally stressed so that on breakage, one glass sheet is caused to break into smaller fragments than another thereby to impart a curvature to the laminate. The conductive coating 3 is applied to a sheet face which will become convex on such breakage. Such a glazing panel may be connected into an electrical circuit which includes means for monitoring the resistance of the coating and for sounding an alarm if that resistance changes due for example to breakage of the glass sheet bearing the coating. Reliability of an alarm signal is promoted because the curvature of the panel on breakage ensures separation of the coating at a fracture line. <IMAGE>

Patent DE-3718614-A1 (DE)
Inventor: HEIDELBERG GOETZ DIPL PHYS
IPC: F16H19/00
Filed: 1987-06-03
Abstract: A device for converting the reciprocating movement of at least one piston (8) of an internal-combustion engine (4) into an oscillating rotary movement of at least one shaft (10), the piston (8) being connected via a flexible strip (24) to a winding-up and unwinding region (20) of the shaft (10). The rotational energy existing during rotary movement of the shaft (10) is used at the end of the working stroke of the piston (8) to rotate the shaft (10) further in the same direction of rotation, so that the strip (24) is subsequently wound in the opposite winding sense onto the winding-up and unwinding region (20) of the shaft (10), and the piston (8) is thereby pulled back by the strip (24). Alternatively, two pistons (8) are provided, with a connecting rod (16) between them, together with strips (24, 24') with opposing winding directions, so that, when the one strip is wound up, the other strip is unwound, and vice versa.

Patent DE-3730314-A1 (DE)
Title: Spur-wheel change-speed gearbox, particularly for motor vehicles
Inventor: FRANKE RUDOLF PROF DR ING
IPC: F16H3/093
Filed: 1987-09-10
Abstract: The invention relates to a spur-wheel change-speed gearbox, particularly for motor vehicles. A spur-wheel change-speed gearbox known, for example, from German Offenlegungsschrift 3544415, has six forward gears with five synchronisable selector clutches which are operated individually. For this purpose, each selector clutch is assigned a special actuating element. These must be actuated individually and it is furthermore necessary to take special measures to ensure that an incorrect gear change does not bring one selector clutch into action before the corresponding selector clutch is out of engagement. This leads inevitably to jamming of the gearbox. To avoid this disadvantage, the proposal is, in a spur-wheel change-speed gearbox, that the actuating elements (25, 26, 28, 29, 32, 33) of respective pairs of selector clutches (c, e; d, f; g, l; h, j) corresponding to one another should be connected firmly to one another by mechanical means, that the two gearwheels (9 and 12) rotatably mounted on the input shaft (5) should be connected rigidly to one another at all times, e.g. by a hollow shaft (11), and that it should be possible to connect the two gearwheels (13 and 14) rotatably mounted on the output shaft (8) to one another selectively by way of a hollow shaft (13a) and by way of a selector clutch (1). <IMAGE>

Title: Fertiliser broadcaster for the distribution of fertilisers and the like
Inventor: DREYER HEINZ DIPL ING
IPC: A01C17/00
Filed: 1987-10-23
Abstract: Fertiliser broadcaster for the distribution of fertilisers and the like, with a supply container having metering elements for at least two centrifugal discs arranged transversely to the direction of travel, each centrifugal disc being equipped with at least one thrown shovel, the distance between the outer edge (spreading edge) of the throwshovel and the axis of rotation of the centrifugal disc and the horizontal throw-off angle between the throwshovel and the tangent drawn at the point of its spreading edge on its path of rotation in the direction of rotation being variable. In order to guarantee an unmistakable setting of the throwshovels which can be fastened in different positions on the centrifugal discs of a fertiliser broadcaster, provision is made for arranging at least two throwshovels on each centrifugal disc, and for marking elements to be located on the centrifugal disc, for each throwshovel, for the purpose of setting the horizontal throw-off angle, the said marking elements being designed differently and/or being designated differently, specifically in such a way that the marking points are each assigned to a throwshovel clearly and unmistakably.

Title: Spray can with consistent compressed air using the tube with an automatic casing roll-up and folding device
Inventor: RADEBOLD CLAUS
IPC: B65D83/14
Filed: 1987-11-05
Abstract: Spray cans are no longer operated by means of gas, as previously, but by means of compressed air. A tube with an automatic casing roll-up device 2 which has been filled with compressed air is inserted in the tube with an automatic casing folding device 1 before it is filled. The spraying operation is brought about by actuation of a press knob 3 by bringing together the compressed air and the liquid contents. Since both tubes contract evenly to the extent of the contents removed during the emptying operation, the strength of the compressed air always remains the same, such that the spraying operation does not lose strength during the emptying operation. <IMAGE>
