Title: Circuit arrangement for mains-independent resistance braking of a plurality of electric motors
Inventor: NIEHAGE HELMUT ING GRAD
IPC: H02P3/00
Filed: 1984-12-21
Abstract: In the case of a circuit arrangement for the mains-independent resistance braking of parallel-connected electric motors (27, 28, 29) via an unbalanced, branch-pair, half-controlled thyristor bridge circuit (1, 2, 3, 4) (which is connected to a single-phase mains supply (20) in motor operation, acts as a braking control device in braking operation and can be turned off) the braking forces are intended to be increased in the region where the speed is relatively low. For this purpose, a braking resistor is connected in parallel with each of the motors (27, 28, 29), via a common switch (18), and a coupling diode (11, 12, 13), which is polarised in the direction of the forward direction of the thyristors (3, 4) of the thyristor-bridge circuit (1, 2, 3, 4), is arranged in the main circuit of each motor (27,28, 29). Once the braking controller has been turned on, a maximum value selecting element (34) selects the maximum-permissible braking current from the main circuits of the motors (27, 28, 29) and causes termination of the current flow in the braking controller, via the turn-off device (5, 6, 14) of the thyristor-bridge circuit (1, 2, 3, 4). <IMAGE>

Title: Circuit arrangement for strain-gauge strips
Inventor: SCHMIEDER LOTHAR DIPL PHYS DR
IPC: G01D5/16
Filed: 1985-03-11
Abstract: The invention relates to a circuit arrangement for strain-gauge strips, in the case of which circuit arrangement at least four half-bridges are connected in a parallel circuit to a current source, the potentials of the half-bridges are connected together in pairs, and the potential differences are determined by means of a differential-measurement amplifier having a very high input impedance and a very low input current. Any desired half-bridge pairs are formed, it being possible to allocate each half-bridge simultaneously to different bridge pairs in order to determine both forces and torques. <IMAGE>
Patent DE-3512969-A1 (DE)
Title: Torque wrench
Inventor: MAYER EBERHARD DR
IPC: B25B23/144
Filed: 1985-04-11
Abstract: In some technical problems, such as, for example, torque wrenches with a ratchet head or an interchangeable tool part, the torque must be measured outside the centre of rotation. Arising at the measuring point is a torque which is dependent upon the length of the lever arm and contains a systematic error which is dependent upon the transverse force, that is, the length of the lever arm, is normally taken into account in the calibration and requires a defined force-inducing point to be maintained. If a different force-inducing point is chosen in practical application, for example by the use of an extension, a considerable measuring error can result. The aim of the present invention is to arrange the geometry of the measuring point in such a way that the transverse force is also detected without an additional measuring point and thus the measuring error can be corrected. This aim is achieved according to the invention owing to the fact that the lever arm has a section of lower rigidity against stressing by transverse force, which section is located in the area of the measuring point and its surroundings, and that the elastic deformation in this section caused by transverse force is also detected by the measurement transducer for the torque, and this deformation signal is superimposed on the signal originating from the torque acting on the measuring point, and that these two signals indicate the actual torque at the tool head. <IMAGE>
Patent DE-3521349-A1 (DE)
Title: Rotary compressor having rigidly joined vane halves
Inventor: STREICHER MAX
IPC: F01C21/08
Filed: 1985-06-14
Abstract: The eccentricity of the rotor in a casing of a compressor strongly affects the volumetric capacity and thus also the cost-effectiveness of such appliances. A limit is set by the amount of heat developed which increases as the capacity grows, especially if the vanes are conventionally made of plastic. Even for vanes made of other materials, improved guidance may be advantageous. If the projecture becomes too large, this results in the vanes jamming in the guidance slots, thus causing increased friction and generation of heat, which lead to failure of the compressor. Attempts have therefore been made to provide the usually plate-shaped vanes with extensions which are to improve guidance in the extended state. In the case of plastic vanes, however, only limited success is possible. The invention therefore proposes to overcome these drawbacks, the vanes in the cantilevered state being guided by guide rods and being stiffened, the guide rods being guided axially in the confronting vane or the slot. In this arrangement, jamming is avoided and the load on the cantilevered vanes is considerably reduced, making it possible to achieve high performance even in the case of plastic vanes. A further advantage is that the guide rods or separate rods are equipped to accommodate compression springs.

Title: Method and device for conveying concrete from a container into a delivery pipe
Inventor: HUDELMAIER GERHARD DR
IPC: F04B9/117
Filed: 1985-07-01
Abstract: The invention relates to a method for conveying concrete out of a container into a delivery pipe by means of two conveying cylinders which can in each case be alternately connected to the container or to the delivery pipe and the conveying pistons of which execute a suction stroke and a compression stroke alternately in relation to one another. The object of the invention is to devise a method of the aforementioned type, in which method a flow of concrete which is continuous to a substantial extent is ensured with simple means when the number of pulses is very low. This object is achieved in that one conveying piston in each case starts its compression stroke before the compression stroke of the other conveying piston has been completed and that the speed of the pistons during the suction stroke is at least temporarily greater than in the compression stroke.

Title: Device for treating leather or the like in a continuous process
Inventor: DOSE LUDWIG
IPC: C14B1/26
Filed: 1985-07-31
Abstract: A device for stretching leather in a continuous process is proposed, having two elastic belts which are situated one above the other, are together guided and deflected via successive rollers and between which the leather is held and conveyed forwards. At least one roller arranged in the starting region has, on its outside around which the pair of belts pass, movement elements which are frictionally engaged with the pair of belts and take the form of roll or pushing segments which exert a load on the pair of belts with a force component not just in the conveying direction, but also transversely to the latter, approximately from the centre of the rollers towards the outside on both sides. As a result of this, the leather is longitudinally and transversely stretched. Then smooth rollers are present which serve to fix the longitudinally and transversely stretched leather.

Title: Arrangement and method for generating images on a projection surface
Inventor: BRAUN KARL
IPC: G03B21/00
Filed: 1985-09-19
Abstract: Attractive distortions of still or moving images which are produced by at least one projector (PR) are generated by projecting these images onto a multifaceted body, eg. a cube (WF). The cube (WF) is set rotating for this purpose with the aid of a motor (MO). An image projected from the projector (PR) onto the cube (WF) starts in each case strongly distorted at the edge of the cube, goes over to normal image rendition as the cube rotates towards the projector, and dissolves once again as the cube rotates further. This produces the impression of flowing movement and greater liveliness. <IMAGE>

Title: Fishing reel with device for hooking and reliably pulling in
Inventor: SLOWINSKI ZDZISLAW DIPL ING
IPC: A01K91/10
Filed: 1985-12-23
Abstract: According to the new invention, the fishing reel is distinguished from preceding models by the following innovations:   a) a helical spring and a ratchet mechanism are incorporated into the drum.   b) a stop arresting device is used in the rotor part.   c) an alternating spool is placed on the drum.   d) axial locking is also used for winding up the helical spring.   The described mechanisms are used for the very rapid attachment of the fish using a small rotation of a crank. Furthermore, the continuous action of the spring (winding and unwinding) ensures that the fish is pulled in in a reliable fashion. This conversion ensures that the angler can react very rapidly the instant a bite is made. The continuous action of the spring ensures that the fishing line is constantly under tension, which tires the fish out rapidly and eliminates inaccurate reactions on the part of the angler. The newly invented mechanism complements important parts of the fishing reel used to date.
