Title: Device for squeezing out window leathers
IPC: A47L13/59
Filed: 1984-06-29
Abstract: Device for squeezing out window leathers which is suitable for squeezing out the water from the window leather when it has become wet by drying off previously washed cars. On the design model according to Fig. 1 of the drawing, the wet window leather is placed between the lower perforated pressure plate (4) which is attached fixedly to the device carrier (1) and the upper movably attached pressure plate (2) with the elastic pressure upholstery (3). By pressing downwards the manual actuation lever (6), which lever (6) is rigidly connected to the crank lever (7), the movable pressure plate (2) with the pressure upholstery (3) is pressed via the pressure rod (8) against the lower pressure plate (4) with the window leather which is laid on it and folded up to a certain extent, in order to squeeze the water out of the said window leather. In order to remove the window leather which is capable of further drying off again, the manual actuation lever (6), and thus also the upper pressure plate (2), is raised. For the pressing stroke when movement is difficult, the crank lever (7) is rotated over the dead-centre position to the stop (9) for the purpose of favourable step-down effect in the dead-centre area in order to achieve a pressing effect even in the locked position. Other pressure plate arrangements, pressure generating systems and pressure transmissions are possible. <IMAGE>

Inventor: LINK LOTHAR
IPC: B43L7/00
Filed: 1984-08-17
Abstract: Right angle templates, including rulers, are provided along their longer straight drawing edge (21) with a row of point-holes (11) corresponding to the main graduations of the measurement scale. Recesses (13, 14) are aligned with respect to a slot (12) which forms the starting point of the row of holes. A retainer part (50) may be inserted into those recesses (13, 14), and a rotation point (51) of their retainer part pierces then the drawing through the slot orifice, thereby enabling to draw circles according to the distances determined by the holes. It is also possible to draw circles of any radius by displacing the rotation point. By inserting the retainer part into the recesses (33, 34) it is possible to place the rotational point at the intersection center (22) of a goniometer, thereby enabling to draw angles and lines by a simple rotation. The insertion side to side of two retainer parts transforms the drawing instrument into a fixed guide rail.

Patent DE-3433535-A1 (DE)
Inventor: BRUNNER RUDOLF
IPC: F16K11/07
Filed: 1984-09-12
Abstract: The invention relates to a two-position switching valve having hydraulic self-holding properties and comprising a closure piston disposed in a flow path for displacement between an open position and a closure position for controlling a pressure between a maximum value and a minimum value, and operatively coupled to a control piston mounted for displacement in a housing. In known switching valves of this type, a creeping approach of respective switching points is scarcely avoidable under certain operating conditions. In accordance with the invention, a reliable switching function is achieved by forming the housing bore as a continuous stepped bore for slidably guiding therein a stepped piston consisting of a closure piston, a control piston, and a piston portion and by providing alternately openable and closable flow connections therein permitting an annular space between the closure piston and the piston portion to communicate with an annular chamber adjacent the control piston in the closure position of the closure piston, and the annular chamber to be pressure-relieved in the open position of the closure piston. These provisions result in the generation of a servo force for abrupt switch-over operation of the valve.

Title: Induction heating apparatus
Inventor: OKUDA TADAO
IPC: H05B6/06
Filed: 1984-12-13
Abstract: An induction heating apparatus comprises an invertor 5 which is driven by means of a DC voltage source (DC power supply 5), has a heating coil 9 and has a switching transistor 11 which is connected thereto in series. The switching transistor 11 is switched on or off by means of a control circuit 35, in order to regulate the current through the heating coil. The control circuit 35 picks off a collector voltage of the switching transistor 11 at the switching point, at which the heating coil 9 and the switching transistor 11 are connected in series to one another through a connection 39. An integrated voltage of this collector voltage is produced in the control circuit 35, and the collector voltage is then compared with the integrated voltage. If the collector voltage is less than the integrated voltage, an output signal is emitted from the control circuit 35 after a certain delay time, and the switching transistor 11 is in consequence switched on. The delay time is preferably adjustable as a function of the magnitude of the collector voltage. <IMAGE>

Title: Fusing-wire trip device for underwater use
Inventor: GRISARD KLAUS DR
IPC: F16K17/40
Filed: 1985-03-06
Abstract: A fusing-wire trip device for underwater use, having a fusing wire which is provided under water and releases a mechanical operating device when it melts through, is constructed according to the invention in such a manner that, with respect to the fusing power which is required for melting through, a wire resistance is selected such that the voltage to be applied to the wire is less than the dissociation voltage of the water. In this way, insulating problems especially with respect to the terminals which hold the wire can be avoided, and the electrical power required is reduced by avoiding current flowing through the water.

Title: Electrical machine, especially a small motor
Inventor: CORBACH RAINER DR ING
IPC: H02K1/17
Filed: 1985-06-12
Abstract: In the case of a permanent-magnet-energized machine, especially a small motor, in order to reduce the power-to-weight ratio of the machine, at least one butt joint (17), which is located approximately in the centre of a two-piece magnet segment (15), is provided in the magnetic return path ring (14) of the stator (13). The machine is constructed on the basis of a defined radial air gap width from the interior, as a result of which tolerances in the radial thickness of the magnet segments (15, 16) and of the magnetic return path ring (14) are compensated for in the butt joint (17). The radial air gap width can thus be selected to be extremely small, and the magnet segments (15, 16) can be designed to be relatively thin (Fig. 1). <IMAGE>

Inventor: REISER KURT
IPC: F16C33/58
Filed: 1985-06-22
Abstract: A mounting assembly for bearing races is provided which enables split races for roller bearings to be fixed on a bearing member in a space-saving system wherein the bearing member includes at least one race groove parallel to two expanding grooves such that narrow webs are left on either side of the race groove. On assembly, for example, of the inner ring of a roller bearing in the race groove, these webs are flanged or crimped against the bearing end faces such that two ends of the axially split bearing race are securely held by appropriate profiling or beveling of the end faces of the race. Assembly may be carried out by inserting a crimping wheel into the expanding grooves and crimping the webs by means of a conically deforming surface. The mounting can be advantageously applied, for example, in connection with an eccentrically drilled bearing bushing for the plain bearings of blanket cylinders in offset printing machines.

Patent DE-3539543-A1 (DE)
Title: Three-phase asynchronous machine with a squirrel-cage rotor
Inventor: FLADERER THOMAS
IPC: H02K17/16
Filed: 1985-11-07
Abstract: A three-phase asynchronous machine is proposed, in the case of which the increase in the resistance and the inductance of the rotor bars, which occurs in the current-displacement state, is increased beyond the extent which can be achieved by the general cross-sectional shape of the bars. This is achieved by means of recesses, which extend transversely with respect to the bar length, along the outer bar edge, that is to say that bar edge in the current-displacement region. The recesses 5 along the upper edge 4 of the individual bars 1 lead to an extension of the current paths 6 in the current-displacement region. If these recesses 5 furthermore extend beyond the bar width and are open on the outside, they also lead to relief of bending stresses on the individual bars and hence also to a reduction in the stress of the connections between the bars 1 and the short-circuiting rings 7. <IMAGE>
