Patent DE-3343382-A1 (DE)
Title: Method for determining the difference in the number of revolutions, circuit arrangement for carrying out this method and method for controlling the strip tension in a contact bend stretching leveller
Inventor: HAAN JOHANN ING
IPC: G01P3/60
Filed: 1983-11-30
Abstract: In order to determine the difference in the number of revolutions of at least two shafts, rollers or the like between at least two measurement times, the shafts or rollers are fitted with a pulse generator, and the pulses of different shafts, rollers or the like are counted separately and subtracted from one another. In addition to the difference in the numbers of pulses, the phase angle of the pulse trains at mutually differing measurement times is determined, and a correction term for the number of pulses is formed. This measurement method is suitable, in particular, for quick determination of changes in the number of revolutions between different measurement times, and is applied with particular advantage in conjunction with a method for controlling the strip tension in a contact bend stretcher leveller in order to achieve a prescribed strip elongation. In order to control the strip tension in such a contact bend stretcher leveller, strip tension is increased in this case in conjunction with increasing strip speed, and reduced in conjunction with reduction in the strip speed. For this purpose, strip characteristics are recorded and a corresponding correction of the strip characteristics is undertaken for different speeds. The tension P1, P2, P3 required for the respective speed V1, V2, V3 in order to achieve a desired value for the stretching rate E is to be calculated on the basis of the measured values at different measurement times (Fig. 3). <IMAGE>

Patent DE-3401497-A1 (DE)
Title: Vacuum switch contact arrangement
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1984-01-13
Abstract: An excitation system formed from circular ring sections (9) is used to excite an axial magnetic field. Each of these winding formers expands to form a contact and electrode body (13) which is in the form of circular sectors and surrounds the subsequent winding former except for the gap width (15). The winding former and contact body are located virtually on the same level. In order to prevent disturbing eddy currents, the contact and electrode bodies are provided with gaps (13a). The excitation and contact system is supported by ribs (12), with the interposition of a stainless steel disc (14) and is supplied with current. These ribs originate as an acute angle from the current-conductor bolt (8). An advantageous variant is to arrange the excitation system on only the stationary switching element. The contact body of the mobile switching element, whose mass has been reduced by this measure, is likewise provided with gaps. <IMAGE>

Title: Gear pump
Inventor: WEBER WALTER
IPC: F04C2/08
Filed: 1984-08-17
Abstract: The pump housing is composed of a plurality of bodies (1, 2, 3, 4) which have the shape of circular discs, are set up in a row, in alignment with one another, and bolted together. One of the bodies (3) has a central hole (12), in which an internal gear (13) is rotatably mounted. Each of the adjacent disc-shaped bodies (2, 4) forms a lateral bearing surface for the internal gear (13) and has an eccentric hole in which a drivable shaft (8) is rotatably mounted. The shaft (8) carries a pinion (11) which engages in the internal toothing of the internal gear (13). The two adjacent disc-shaped bodies (2, 4) each have a through hole, that of one of the bodies emerging in the intake region and that of the other body emerging in the delivery region of the intervening central hole (12) containing the internal gear (13) and the pinion (11). This modular principle of construction makes possible economical, simple production of the gear pump by means of a small number of components. <IMAGE>

Title: Method and device for constructing bridge superstructures
Inventor: LOHMILLER HERMANN DR ING
IPC: E01D21/06
Filed: 1984-11-15
Abstract: In the construction of a bridge, a superstructure supporting framework is supported at the front on a travelling and lowering scaffold 7 and connected rigidly to the latter in the longitudinal direction and transverse direction. The scaffold is arranged on an auxiliary bridge in front of the front end of the supporting framework. In this case, the rear part of the supporting framework is mounted unrotatably on as wide a base as possible on a follower or a rear travelling or lowering scaffold and is drawn along on the back of the already complete bridge superstructure until the lowering position is reached. The front scaffold is then rigidly connected to a jib boom of the auxiliary bridge or to a bridge pillar, whereupon the horizontal connection to the supporting framework is released. Subsequently, the supporting framework is lowered into its final position via lowering devices. Finally, the auxiliary bridge is advanced further by a bay length while the front scaffold remains on a pillar and there awaits the arrival of the next supporting framework.

Title: Baggage space with changeable volume in the rear of motor vehicles
Inventor: BUTZ EUGEN OTTO
IPC: B60R5/00
Filed: 1984-12-24
Abstract: The invention relates to a baggage space with changeable volume of the known so-called "ski bags" type, the container bag (1) being non-positively held at the circumference in a holding frame (5), which is a single piece of material, by means of a plug-in frame (10). The flap (27), which preferably covers only part of the opening (4) of the mouth, can be actuated from the back seat through a slot which is to be opened from the passenger compartment. The container bag (1) can also be unfolded and folded together from here, so that the operator does not have to leave the passenger compartment. Assembly of the holding frame (5) and therefore of the whole device is carried out in a simple fashion by means of a snap-on connection. A special bearing configuration of the flap (27) prevents rattling and facilitates pivoting (Fig. 1). <IMAGE>
Patent DE-3448046-A1 (DE)
Title: Vacuum cleaner handle
Inventor: JACOB GERNOT
IPC: A47L9/26
Filed: 1984-08-17
Abstract: The vacuum cleaner handle is connected to a guide tube of the vacuum cleaner via a plug-in connecting part and has a handle part running at an angle to the guide tube. A receiving device for an electric cable of the vacuum cleaner, preferably in the form of a cable drum, is arranged below the handle part in such a way that the receiving device is located below the axis of the guide tube. This arrangement of the receiving device for the electric cable results in a favourable position of the centre of gravity of the vacuum cleaner handle in its connection to the guide tube of the vacuum cleaner, such that the vacuum cleaner can be guided very easily and conveniently without increased effort or increased skill being required for this purpose.

Title: Guard and servicing device for ink jet printing devices
Inventor: MICHEL INGO DR ING
IPC: B41J2/165
Filed: 1985-03-11
Abstract: The invention relates to a guard and servicing device for ink jet printing devices with ejection of ink droplets as required. The primary aim of the invention is to provide such an adjusting movement of the nozzle covering element for introducing a nozzle rinsing and cleaning process by machine, in which adjusting movement an effective flow of liquid can be formed even in partially or completely blocked nozzles. The object of the invention is therefore to allow actuation by machine of the overpressure device and of the covering and cleaning device utilising the printing carriage movement, in which the covering element only exposes individual nozzles one after the other as a function of the generation of overpressure. According to the invention, for this purpose the covering element, which is divided by cleaning channels into one opening region and two covering regions, is connected to an electromagnetic drive via a lever and spring system for setting it in the operating position and returning it to the rest position, and the printing carriage, which is controllable in terms of path and speed in the transition and flushing or cleaning region when it has passed over the boundary of the writing region, is provided with a release member or pressure piece for actuating the overpressure device and for the adequate setting movement of the covering element into the flushing and cleaning position, said release member or pressure piece interacting with a corresponding contact member or impact moulding of the machine frame. <IMAGE>
