Title: Separating device for sheet-type copying carriers
Inventor: HALLMANNSEDER LUDWIG
IPC: B65H3/06
Filed: 1982-02-20
Abstract: In a separating device for sheet-type copying carriers, feed rollers (3) are provided which are driven intermittently by means of a detachable drive coupling (4) and feed the copying carrier to transport rollers (17, 18) on the equipment side whilst overcoming the resistance of corner separating elements (12a) which are fixed to the equipment and against which the surface of the pile (1) rests under the effect of a pressure spring (11) on the pile side. In order to prevent the next sheet being carried along unintentionally at the end of the transporting movement, the feed roller has a flat portion (3a) which, when the drive coupling has been released from a catch device (6-8), is moved into a position parallel to the pile in which it does not contact the surface of the pile. In this position of the feed roller, individual sheet feeding is also possible. <IMAGE>

Title: Typewriter
Inventor: DIEHL KURT
IPC: B41J13/12
Filed: 1982-03-09
Abstract: The invention relates to a typewriter for the lettering of cards of the most diverse materials. In the lettering of such cards, it is important that they can be clamped quickly and reliably, can be oriented in a simple way and do not change their position during the typing operation. Known typewriters are based on conventional typewriters with platens and clamping devices involving an especially high outlay or on those devices in which the cards are clamped and hammers strike these from the rear and press them against a corresponding type. Such systems involve a high outlay, are complicated and also do not provide an exact type image. In contrast to this, the object of the present invention is to provide a typewriter, by means of which it is possible to letter cards in a simple way, with a more exact type image and more quickly than with conventional machines. The object is achieved in that the typewriter has one or more bars which are arranged with the longitudinal axis parallel to the direction of typing of the types and are intended for holding the material to be lettered and of which one is at the same time an abutment for the striking types.

Title: Electrical switch
Inventor: KING ALBERT
IPC: H01H23/20
Filed: 1982-03-12
Abstract: The switching mechanism of a bistable snap switch of miniaturised design comprises, in addition to the cap-like operating device (15) which is supported on a base (1) such that it can rotate and completely surrounds the switching mechanism, an approximately U-shaped bracket (18), with bracket limbs (21 and 22) of unequal lengths, and a switching spring (14), which is constructed as an approximately U-shaped spring clip. The latter is connected, in each case such that it can pivot, to the contact arm (2) on the one hand and to the shorter bracket limb (21) on the other hand, its line of action passing through the neutral position in a known manner during switching over. For assembly, a hooking projection (23), which is integrally formed at the free end of the longer bracket limb (22), is initially hooked to a hooking shoulder (24) of the base (1). Subsequently, the operating device (15) is placed over the bracket and the complete switching mechanism, and subsequently connects it via bearing pegs or the like to the base (1). The hooking projection (23) is released from the hooking shoulder (24) either during the bearing installation or after a first pivoting movement of the operating device (15), so that the bracket (18) can assume its final position in the cavity (26) of the operating device (15). <IMAGE>

Patent DE-3222797-A1 (DE)
Title: Short-circuit protection device for converters
Inventor: SCHALLHORN RALF ING GRAD
IPC: H02H3/04
Filed: 1982-06-16
Abstract: The arrangement (3) detects the short-circuit current in the frequency range < 40 Hz by means of a shunt resistor (5), and by means of a current transformer (4) in the frequency range >/= 40 Hz. The voltage which is applied to the load (5) of the current transformer (4) or to the shunt resistor (R) and which is directly proportional to the short-circuit current controls a triac (6) independently of the half cycles. In the short-circuit case, the triac (6) enables a permanent energy store (11) to trigger a bursting charge fuse (2) which protects a converter (1). The readiness of the energy store (11) to operate is monitored by means of a glow lamp (13). If the voltage is less than the triggering voltage of the latter, a report is made and the converter (1) is isolated, by means of optical coupling. Since virtually no energy can then be drawn from the energy store (11), the remaining stored energy ensures readiness to trigger until the converter (1) is disconnected. The susceptibility of the short-circuit protection device (3) to defects is low because of the deliberate minimising of the auxiliary circuits and voltages and of their necessary monitoring. <IMAGE>

Filed: 1982-06-24
Abstract: A hydraulic control system for the fluid flow between a pressure-fluid source (3) and a user device (6), which can be a control cylinder for a component or a tool of an earth-moving machine, contains a distributor (1), inserted between the pressure-fluid source and the hydraulic user device, and an auxiliary valve (7) which produces a connection between the pressure-fluid source and a drain tank (4) when the distributor is closed. The auxiliary valve has a housing (8) with a cylinder hollow space (9) into which a piston (10) is inserted in a slidable manner, which piston (10), under the action of the fluid pressure coming from the pressure-fluid source, is displaced against the action of a spring device (16) into a position which allows the fluid to flow to the drain tank. A device (17) is provided in order to increase the preloading of the spring device as soon as the distributor is moved into its open position. <IMAGE>
Patent DE-3228578-A1 (DE)
Title: Measuring device for measuring the thickness of blankets
Inventor: ROCKS JOSEPH CHARLES
IPC: G01B5/06
Filed: 1982-07-30
Abstract: A measuring device for measuring the thickness of blankets in printing presses has a housing which contains a measuring and display device such as a dial gauge, there projecting from the housing two pointed feelers which penetrate a blanket without damaging it, and which establish electrical contact with a metal surface below the blanket. A feeling device connected to the dial gauge is arranged between the feelers, and a current source is connected to the feelers in the housing via a lamp or another signalling device. When the two feelers and the feeling device are pressed against the surface of a blanket, the feelers pass through the blanket and an electrical connection is established outside the housing via the metal surface below the blanket, as a result of which the lamp lights up and the dial gauge gives a direct display of the thickness of the blanket.
Patent DE-3231763-A1 (DE)
Title: Deceleration signal generator
Inventor: DERER ANDREAS
IPC: B60Q1/44
Filed: 1982-08-26
Abstract: The invention has the aim of avoiding rear-end collisions of motor vehicles by virtue of the fact that both braking processes and other decelerations are indicated to the driver of the following vehicle by a changeable signal in such a way that said driver can also detect the degree of deceleration from the indication. The intensity of the signal generator, for example its lighting power and its lighting surface, can therefore be changed. It is changed by a controller and by a shutter. The controller and the shutter are actuated by a mass which is arranged in such a way that when the vehicle is decelerated it is displaced by its inertial force counter to the force direction of a spring, in which case it also actuates a switch which closes the current to the signal generator. In the case of braking, a hydraulic piston also pushes forward the mass if the said piston is connected to the brake line. If the deceleration stops, a spring returns the mass and the piston to the initial position, in which case the signal generator is switched off again.

Title: Slipring arrangement for supplying energising current to high-power turbo generators
Inventor: BLANK KARL
IPC: H02K9/28
Filed: 1982-08-28
Abstract: The subject-matter of the application is represented comprehensively by Fig. 1 of the application which is attached to the abstract. Fig. 1 of the application shows the slipring arrangement in a longitudinal section, with all the details for the structural construction and cooling. For improved cooling, each slipring is split into a number of individual sliprings which are shrunk onto intermediate shrink-rings which are insulated from the slipring shaft, these intermediate shrink-rings at the same time being used for supplying current to and taking it away from the sliprings. Cooling-air ventilators are arranged on the intermediate shrink-rings, in front of and behind the sliprings. Semicircular busbars are inserted in an insulated manner into the hole in the slipring shaft. Via energising-current supply bolts, which are screwed into these busbars, are cooled together with them and are connected to the live intermediate shrink-rings of the sliprings by contact nuts, these busbars produce current inlet and outlet flow for the energising winding of the turbo rotor. The energising-current bolts are provided in front of and behind each slipring in a twin arrangement, for the high current intensities which have to be coped with. <IMAGE>

Title: Impact protection for two-wheeled vehicle riders on posts
Inventor: DOMHAN MARTIN
IPC: E01F15/04
Filed: 1982-11-29
Abstract: For fallen two-wheeled vehicle riders, impact against lateral obstacles next to the roadway, in particular against any sharp-edged posts, represents a particular danger. According to the invention, such posts are therefore to be equipped with impact-damping elements which are suitable for considerably reducing the risk of injury on impact by absorbing all or part of the movement energy of the impacting body and distribution of the forces in the impact region over a larger area. The impact dampers made of plastically or elastically deformable plastics with weather-resistant surface or of corresponding metal constructions are fastened in a theftproof and twistproof manner on the posts, against which they are to provide protection, in such a way that they cover the possible impact region of fallen two-wheeled vehicle riders. A preferred area of application is the posts of protection boards, in particular in curves, in the region between the protection board rail and the ground. <IMAGE>
