Patent DE-3231095-A1 (DE)
Title: Logical switching element with tri-state output in Schottky TTL technology
Inventor: BARRE CLAUDE DIPL ING
IPC: H03K19/082
Filed: 1982-08-20
Abstract: To avoid that with an otherwise high-impedance output, the output transistor, connected to reference potential at the emitter end, becomes conductive for a short time and virtually short-circuits the connected bus with respect to the reference potential if there is a transition from a low binary signal level to a high binary signal level on the bus, a capacitor is arranged between the output and the base of a transistor, the collector of which is connected via a resistor to the base of the said output transistor. In integrated circuit construction, this capacitor is implemented by means of a reverse-connected diode or by the base-collector capacitance of an additional transistor.

Patent DE-3241233-A1 (DE)
Title: Drive unit for pressure-medium drives
Inventor: FALKENSTEIN JOHANNES
IPC: B30B1/32
Filed: 1982-11-09
Abstract: A quadrate guide (6) for the drive unit (1) is formed between two side walls (4) and two intermediate walls (5) in the frame (2) of a machine stand. The pressure-medium cylinder (15) of the said unit is suspended with play on a bearing pin (19) and provided with connection lines (25, 27). The piston rod (16) is rigidly connected, via a connection plate (14), to a quadrate jacket tube (7), which is supported relative to the guide (6) by slide plates (9) or a slide tube and relative to the cylinder (15) by a supporting ring (23) arranged in the radial plane of the piston (22). Secured in a centred manner at the driving end (21) of the cylinder (15) is a second supporting ring (28), which is seated with a positive fit and in sliding fashion in the jacket tube (7) and surrounds the piston rod (16). Both supporting rings can be integrally connected, in the form of a collar-type sleeve with collars. The slide plates and supporting rings can be composed of a wear-resistant, in particular self-lubricating material such as polyamide or polyamide blended with PTFE. Due to the complete support in two radial planes and the rigid connection between the jacket tube (7) and the piston rod (16) in the connection plate (14), a precise longitudinal guide is formed and lateral forces are taken up on large bearing faces and hence with little wear. <IMAGE>

Title: Vibration damper having a static seal between the piston rod guide and the container inner wall
Inventor: AXTHAMMER LUDWIG
IPC: F16F9/36
Filed: 1983-01-17
Abstract: For vibration dampers or shock-absorber struts, a disc is arranged in order to provide a static seal on the piston-rod outlet-side end, which disc is pressed against the inner wall of the container with a high surface pressure. This disc is preferably of conical construction and is pressed flat when the container is closed, so that its diameter increases and the disc is thus pressed against the inner wall of the container with a high surface pressure. For example, Fig. 1 shows the disc acting as a static seal after the container has been closed. <IMAGE>

Title: Coin store for storage and delivery of coins of the same value
Inventor: MILLER GERT DIPL ING
IPC: G07F1/04
Filed: 1983-03-03
Abstract: The invention relates to a coin store for storage and delivery of coins of the same value in a helical storage channel, in which the coins can be stored and if necessary transferred into an end cash-box in one direction, and in the opposite direction are movably arranged for the delivery of coins when too many have been put in or of the deposited coins when the counting process is interrupted. The coin store is for this purpose equipped with monitored coin channels for the insertion of coins, for the transfer into an end cash-box, and for return of coins. In order to increase the storage capacity of such a coin store and at the same time to reduce the manufacturing cost, the storage channel is formed by several mutually parallel coil springs distributed uniformly over the circumference of a circular cylinder, a respective coin being received between their individual turns, and the intermediate webs which each together with a coil spring form an axial through coin channel can be rotated by a motor about a middle axis in both directions of rotation by a portion of a revolution corresponding to the number of the coil springs. During this rotation the individual coil springs are each simultaneously turned about their own longitudinal axes by a portion of a revolution corresponding to the number of the coil springs.

IPC: A47K10/38
Filed: 1983-03-22
Abstract: The paper roll support provided with a brake consists of two identical hanging rods (2) and a brake plate (3) and the hanging rods run through loose holes in the two ends of the brake plate. The upper short ends of the hanging rods, which are bent at 90 DEG , are mounted loosely in the fastening arrangements (1) or holes and the lower ends of the hanging rods, which are also bent at 90 DEG  in the same direction and the same plane as the upper ends, extend in the hard paper core (5) of the paper roll (4). The brake plate (3) presses with its own weight the paper roll (4) which has a perforated paper web (6) which can be unrolled with uniform pulling, the brake plate (3) pressing the paper roll with its suitably selected weight and with friction. The brake plate (3) can e.g. be coated or given such a shape that the friction is increased. The drying paper or the like can be separated easily with only one hand with an obliquely downwardly directed tug. On changing the paper roll, the brake plate is lifted upwards and at the same time the hanging rods are oulled outwards, the paper roll (4) freeing itself and it being possible to place a new paper roll in its place. <IMAGE>
Patent DE-3317245-A1 (DE)
Title: Coal dust ignition burner
Inventor: BUDE FRIEDRICH DIPL ING
IPC: F23C7/02
Filed: 1983-05-11
Abstract: The invention relates to a coal dust ignition burner for operation with moist coal dust. Dust moisture contents of up to 25% with a size class B particle are to be permissible without the use of a permanent ignition burner. A preheating of the burner and of the coal dust and also a control of the quantitative throughput of coal dust and air are to be ensured by way of a controllable medium. Furthermore, an inner and outer recirculation are achieved, in order to ensure a rapid heating up of the components of the ignition burner. This is achieved when the outlet of the intake pipe is provided with a controllable steam-operated ejector ring nozzle, and the ejector ring nozzle is connected to an inner pipe and/or the outlet of the inner pipe is connected to a muffle which forms a re-entrant. The muffle is, or is not, provided with heat storing material, and the re-entrant is formed by a widening of the muffle towards the inner pipe in a diameter proportion of 1.5:2.5. Since the ignition burner is used directly for conveying a mixture of coal dust and conveying gas, a simple plant technology combination is possible. <IMAGE>

Title: Process and device for compensation of thickness variations in the continuous compression moulding of boards
Inventor: SEEGER GUENTER
IPC: B30B5/06
Filed: 1983-06-30
Abstract: A process for the compensation of thickness variations in the continuous compression moulding of chipboards, oriented strand boards, hardboards, medium density fibre boards or the like by means of a continuous press having a feed zone, a high-pressure zone, a medium-pressure zone and low-pressure or holding zone is described. In order substantially to increase the degree of compensation and simultaneously to attain an especially good bulk-density profile across the board thickness as well as high quality surfaces, the position and size of board regions deviating from the thickness setpoint value are determined on the press discharge side and then, dependent on position, the moulding pressure is varied in the direction of passage in the low-pressure or holding zone, forming a compensation region, to an extent dependent on the magnitude of the deviation and/or over a distance dependent on the magnitude of the deviation.

Title: Smelt cyclone for the reaction smelting of ore concentrates
Inventor: RACHOR FRANK
IPC: F27B15/00
Filed: 1983-12-27
Abstract: The invention relates to a smelt cyclone for the reaction smelting of ore concentrates, especially particulate sulphide nonferrous metal concentrates, with a cover through which the concentrate particles are introduced from above, and with a tangential feed for the reaction gases. In known smelt cyclones, the ore concentrates are introduced either off-centre from above, directly in front of the tangential reaction gas feed, or tangentially into the smelt cyclone together with the reaction gas. The concentrate particles are thus centrifuged immediately after entry into the smelt cyclone onto its inner wall, so that the desired physical and chemical reactions only proceed with difficulty or incompletely. By the special constructional form of the smelt cyclone according to the invention, with a central concentrate feed pipe and several, at least two, tangential reaction gas feed ducts, it is very advantageously achieved that the residence time of the particles in the gas phase is extended such that the desired reactions proceed completely in the suspended stream before the particles strike against the inner wall of the cyclone.
