Patent DE-3330562-A1 (DE)
Title: Friction clutch, especially for motor cycles
Inventor: GILGENREINER GEORG
IPC: F16D23/12
Filed: 1983-08-24
Abstract: The invention relates to a mechanically or hydraulically actuated friction clutch, especially for motor cycles, comprising two clutch main parts, the drive and output part, which are frictionally connected by way of plates under spring force. When disengaging the clutch, the spring force on the plates is cancelled and the frictional contact interrupted. For bridging the speed in this process a ball bearing is fitted between the two clutch main parts as close as possible to the clutch centre, so that the lateral forces occurring in the vicinity of the clutch centre which lead to destruction of the bearing are avoided.

Abstract: 1. A circuit arrangement for measuring time intervals in particular very short time intervals, and for indicating the measured time interval in digital form, being supplied with a start pulse which indicates the start of the time interval to be measured and with a stop pulse which indicates the end of the time interval to be measured, and using a charging arrangement and a counting device which counts oscillator pulses, characterised in that a first delay element (ZG3) is supplied with a start pulse (SE1), that a second delay element (ZG4, ZG5) has a longer delay time than the delay time of the first delay element (ZG3) and supplied with a stop pulse (SE2), that the first delay element (ZG3) is connected to the set input of a bistable trigger circuit (FF) and the second delay element (ZG4, ZG5) is connected to the reset input of the bistable trigger circuit, that the output of the bistable trigger circuit (FF) is connected to an oscillator (OSZ) switched on when the bistable trigger circuit is set and switched off when the bistable trigger circuit is reset, that the charging arrangement consists of a first and a second charging circuit (LD1, LD2) which, during the time interval to be measured, can each alternately be connected to a constant current source (KQ) for a whole period of the oscillator pulse for the generation of a charging voltage proportional to said oscillator pulse, or in the event of the stop pulse for a shortened period, and each be alternately discharged by a discharging circuit (ET1, ET2) in push-pull to the connection to the constant current source, that the outputs of the charging circuits (LD1, LD2) can be connected by a first multiplexer (MX1) with the current potential to an amplifier circuit (VST), that the output of the amplifier circuit (VST) is connected to an analogue-digital converter (AD) switched on by a start signal (ZS6) when the stop pulse (SE2) has occurred so that the only charging voltage (UD) proportional to the duration of the shortened oscillator pulse is converted into a digital value, and that a counting device (FL, FR, NR4, NR5, BZ) is provided, which counts the whole period pulses emitted by the oscillator (OSZ).

Title: Heat-treatment combined with transport of thermoplastics
Inventor: KAEUFER HELMUT PROF DR
IPC: B29B13/02
Filed: 1983-10-05
Abstract: The material emerging from a plasticating device is first caught in a vessel. A heat treatment of the material cake with the desired temperature profile takes place on the transport path to the next processing stage. The duration of the transport is set to the time necessary for the heat treatment. The transport, and therefore the heat treatment, can be co-ordinated intermittently in the same cycle with the following processing stage by adding one or more vessels.
Patent DE-3338051-A1 (DE)
Title: Electrically controlled optical switch
Inventor: LOESCH KURT DR RER NAT
IPC: G02B6/35
Filed: 1983-10-20
Abstract: The optical switch consists of two ceramic parts made from piezoelectric ceramic material, in which optical waveguides are embedded. One ceramic body (5) is joined in a two-dimensional fashion to a substrate (1), while the other ceramic body (2) is a part of a flexible element made from the ceramic body (2) and the metal plate (3). The flexible element (2, 3) is mounted on the substrate (1) at the end averted from the other ceramic body (5). The optical waveguides (7 or 8) embedded in the ceramic bodies (2 or 5 respectively) are situated opposite one another on the same optical axis such that the light flux can pass over from one optical waveguide into the others. By applying a voltage to an electrode arranged on the ceramic body of the flexible element (2, 3), and to the metal plate (3), the end of the flexible element (2, 3) situated opposite the ceramic body (5) is bent away from the substrate (1), and the light flux between the optical waveguides (7, 8) is interrupted. Multiple switches and changeover switches can also be constructed in the same way. By producing the ceramic bodies (2) and (5) from a single ceramic part with a capillary duct and sawing the part after the insertion of an optical waveguide in the duct, adjustment of the ends of the two optical waveguides with respect to one another is rendered superfluous. It is possible in this way to obtain very simple optical switches which are easy to produce. <IMAGE>

Title: Plastic casing for electronic watches
Inventor: BERNHEIM RONALD ARTHUR
IPC: G04C10/00
Filed: 1984-02-17
Abstract: The plastic bottom (1) of the watch casing has, in the area of the battery, an opening (7) in whose boundary wall a metal ring (4) consisting of brass and having an inner thread (6) is potted. A steel screw cover (3) which, with the interposition of a resilient O ring (2), is screwed firmly into this metal ring (4), ensures perfect water tightness of the watch housing. In this way, a very robust and virtually wear-free screw connection is formed from metallic parts of different hardness. Instead of a separate O ring it is also possible to have an annular flange formed on the plastic bottom wall bounding the hole (7), which flange is clamped between the metal ring (4) and the screw cover (3) when the latter is screwed tight. <IMAGE>

IPC: B65H39/04
Filed: 1984-08-04
Abstract: The invention relates to a monitoring and control device in collating systems, especially for collating and joining sheets in continuous sections, such as continuous sections for the saddle stitching of leaflets. The aim of the invention is to produce a monitoring and control device of this type which can be used in a variable fashion and exhibits a high degree of operational reliability. The technical object of the invention is to design the device in such a way that the conveying device can be operated with format-adjusted separation and different feeding of the feeding systems, and that mechanical impairment of the sheets or feeders during the control operations is prevented. The object is achieved in that a device which activates the sensor device and switches the station in question on and off is assigned at least to each sensor device of the feeding stations, a shift register with a number of shift elements which equals the number of sheets between this station and the next one is assigned to all stations, the said shift registers are connected to a display device, and a device for changing the format and modifying the feeding action is arranged downstream.

IPC: F15B15/20
Filed: 1984-08-10
Abstract: The invention relates to a double-acting working cylinder with which different forces can be exerted in various sections of the overall piston stroke. For this purpose, the working cylinder has two pistons of different diameter which are allocated to a common piston rod and run in a cylinder housing with housing sections of correspondingly different inside diameter.
