Title: Method for measuring the cross-sectional surface of profiled billets and device for carrying out said method
Inventor: GERLACH JUERGEN
IPC: B29C48/355
Filed: 1981-04-04
Abstract: For the purpose of continuously measuring the cross-sectional surface of continuous profiled billets, the profiled billets are moved through a compressed air zone, and the air quantity they displace in the process is continuously measured and used to control or readjust the profile cross-section. The measuring device has a matrix-like nozzle, through which the profiled billets pass in a contactless fashion, and which has an inlet for compressed air and an outlet for compressed air that does not flow out through the nozzle opening. The amount of compressed air flowing from the outlet is measured and forms a measure of the cross-sectional surface of the profiled billets.

Title: Circuit arrangement for peak-value rectification
Inventor: HERRMANN WALTER DIPL ING
IPC: G01R19/32
Filed: 1981-04-11
Abstract: The invention relates to a circuit arrangement for peak-value rectification by means of which good temperature compensation, low and balanced loading of the signal source and a large output voltage is achieved. The circuit is intended to operate even with input voltages below the threshold voltage of a diode. This is achieved by the fact that the input signal is divided into two part-signals and is in each case shifted in potentials by one diode threshold voltage in the positive and negative direction via a forward-polarised diode, and the part-signals are rectified via further diodes so that the positive and negative peak values are present at the part-outputs. <IMAGE>

Title: Chip-comminution vehicle
Inventor: CARLSSON JAN ERNST KJELL
IPC: B02C21/02
Filed: 1981-10-22
Abstract: Chip-comminution vehicle for comminuting trees and the like to form chips, especially chips of combustible material, having a cross-country tractor with an engine, with a chip comminutor, with tools for cutting down (felling) and for lifting trees, so that they can be introduced into the chip comminutor, and furthermore with a member for connection to a container device serving for collecting the comminuted chips. To obtain a chip-comminution vehicle, by means of which even a first dig can be carried out with minimum damage to the ground or to trees still standing, and moreover to avoid an incorrect selection as a consequence of a necessary range of activity for the vehicle, the tractor is of the small-tractor type and can be designed for walking drivers. The conventional crane with a reach of a plurality of meters in the lateral direction is exchanged for a catching and lifting head which is mounted on the chip comminutor via a parallel link system for the purpose of felling trees with roots and of lifting an upright tree to the chip comminutor. Since the head cannot be moved laterally outside the vehicle, the vehicle width and the vehicle weight can be reduced, whilst ensuring the same stability against tipping over. The operating capacity is thereby extended. The container arrangement can be an exchangeable bag.

Patent DE-3210850-A1 (DE)
Title: Ignition circuit for thyristors connected in antiparallel
Inventor: SHIRAISHI HIROTAKA DIPL ING
IPC: H02M1/08
Filed: 1982-03-24
Abstract: The invention relates to an ignition circuit for a thyristor arrangement having two antiparallel-connected thyristor branches (1, 2). In this arrangement, the thyristors (1, 2) of the thyristor branches are normally ignited by means of a photo-ignitable auxiliary thyristor (3) which is connected via a diode bridge (5A to 5D) to the gates of the thyristors (1, 2) to be ignited and, on the other hand, to their anodes. In parallel with the photo-ignitable auxiliary thyristor (3), a threshold element (8), for example a break-over diode, is connected. If the voltage present across the thyristors (1, 2) exceeds a particular voltage predetermined by the threshold value of the threshold element, the threshold element (8) conducts and the thyristors loaded in the forward direction are ignited. The voltage present across the thyristors (1, 2) thus collapses and the thyristors (1, 2) are protected against overvoltage. <IMAGE>

Patent DE-3217083-A1 (DE)
Title: Friction false twister
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D02G1/08
Filed: 1982-05-07
Abstract: What is described is a false-twisting device consisting of two discs which can be driven to rotate in opposite directions and between the end faces of which a yarn is clamped and at the same time twisted and conveyed. At least one of the discs is made flexible and is pressed down from its rear side, in the region of the yarn-clamping line, by two press-down devices located opposite one another on the mid-perpendicular to the disc centres and having a press-down ram, in such a way that the disc bulges locally against the yarn and clamps this. According to the invention, with a device designed in this way it is possible, during the feed of a drawing-frame sliver drawn to yarn fineness by a drawing frame preceding the false-twisting device, to produce spun yarns. In these, less sharply twisted core fibres are tied in by means of more sharply twisted outer fibres.
Patent DE-3219552-A1 (DE)
Title: Pressure-reducing valve
Inventor: LEIN GUENTER PROF DR ING
IPC: G05D16/02
Filed: 1982-05-25
Abstract: The invention relates to a pressure-reducing valve, e.g. for the supply of water, which maintains the pressure in the downstream lines constant without auxiliary energy, irrespective of the upstream pressure, and ensures that the reduced and controlled downstream pressure is as independent as possible of the upstream pressure. The independence of the upstream pressure is guaranteed by the fact that the outside diameter of the closing/opening plunger is continued as far as the control plunger. Due to the adjustable viscous restrictor, the pressure change in the low-pressure line is transmitted to the control plunger with a time delay. A damping device arranged axially above the control plunger and having a further viscous restrictor ensures that the closing plunger is not overdriven and imparts to the valve a P/I control characteristic with superimposed permanent P offset. The simple construction makes it possible to predetermine the time response of the valve and hence of the pressures by calculation, and it can therefore be preset in an optimum way.

Title: Built-in double-profile cylinder lock
Inventor: NIEDERDRENK GERD
IPC: E05B27/00
Filed: 1982-07-16
Abstract: The invention relates to a built-in double-profile cylinder lock (15, 16), the cylinder core of which is subdivided into a plurality of cylinder-core longitudinal parts (2, 7, 3, 8, 4, 9, 5, 10, 6) which are arranged coaxially relative to one another and through which a key (13) designed as a flat key can pass and which are preferably all designed as locking-pin carrier discs and bear axially flush (on the end face) against one another. The flat key (13) can pass through all or only a selection or number of the cylinder-core longitudinal parts (2 to 10) and release their pin tumblers (17, 18). The cylinder-core longitudinal part (4) having a locking bit (driver 11) and preferably arranged in the middle region of the length of the lock possesses at least one locking-pin tumbler, the key (13) being, for example, so long that it can lift out the pin tumblers of this cylinder-core longitudinal part having the driver (11). As a result, on the one hand, a burglar-proof lock of robust design with a very large number of locking permutations is obtained and, moreover, can be used in numerous variations and, on the other hand, is especially suitable for master locking systems. <IMAGE>
Patent DE-3227540-A1 (DE)
Title: Pressure relief valve
Inventor: TRAUTEWEIN HERBERT
IPC: F16K17/04
Filed: 1982-07-23
Abstract: The invention proposes a pressure relief valve (Figure 1) with a sealing ring (25) which is pressed radially against the shank of the closing element (17) by pressure medium. Reliable sealing is thereby achieved. The sealing ring (25) adjusts itself automatically. The pressure compensation which takes place at the sealing ring (25) when the valve opens, and the associated elastic springback of the sealing ring (25) in to the annular groove (21) prevent erosion and wear of the sealing ring (25). A long life of the sealing ring (25) can thus be achieved. The pressure relief valve is of simple and compact construction and is suitable for various applications. <IMAGE>
