Title: Pressure sensor screw-fitting into IC engine block - has membrane moving rod acting on piezoelectric transducer
Inventor: KLEINSCHMIDT PETER DIPL PHYS
IPC: G01L23/22
Filed: 1980-06-06
Abstract: A piezo-electric transducer (20) is connected via a rod (26) to a membrane (15). The sensor is fot fitting into the engine block (13) and detects knocking. The pressure in the piston chamber acts on the membrane, whose resulting movement is transferred by the rigid rod to the piezo-electric transducer where it is converted into an electrical signal. The transducer consists of a piezo-electric plate on a metal plate (24). The rod is made of steel and may be hollow. The bimorphous transducer has an external thread (18) that allows it to screw into a threaded hole in the engine block. The metal plate faces the piston chamber and is in good thermal contact with the sensor's casing (17), which acts as a heatsink. The membrane has a built-in curvature that does not change sign when the membrane is heated by the burning gases. The membrane consists of a thin sheet of titanium, tantalum or tungsten. A ring may be located between the rod and the membrane. The advantage lies in simplicity and in the sensor's being fitted permanently into the engine.

Abstract: In the method, the yarn taken off a feed reel (12) passes through a first tension-free loop, whose sag is kept constant with the aid of controlled drive rollers (14, 16). The yarn is then tensioned (19, 22) and passes through a hot-air chamber (36), provided for shrinking and puckering, with part of a second tension-free loop, whose sag is also kept constant with the aid of drive rollers (23, 28). The yarn is then tensioned (36, 38) again. The shrinking and puckering actions are determined from the differences in speed of the drive rollers (16, 23, 28, 40). <IMAGE>

Title: Air cooled brake disc for vehicle - has spaced rings connected to hub by radial spacer arms, increasing in thickness for rigidity
Inventor: SCHMIDT HERBERT
IPC: F16D65/12
Filed: 1980-07-16
Abstract: The air cooled disc for a vehicle disc brake is designed for rigidity. It consists of two friction rings spaced apart to permit air to circulate between them, attached to a ring shaped hub with splines around the inside so that it can slide axially into position along a supporting member. The two rings are connected by bridging sections in the form of radial arms, so as to form square section radial air channels between the rings. These arms terminate in extensions connecting them to the hub. These extensions slope outwards towards the hub, so as to project beyond the width of the rings.

Title: Bottle with screw cap closure - has cap connected by frangible stays to ring of smaller dia. and below bulge on bottle neck
Inventor: BRANDES CARLOS ENRIQUE
IPC: B65D41/34
Filed: 1980-08-19
Abstract: The bottle includes a neck (1) which has a bulge (2) running around its circumference. A screw closure (3) for the bottle is connected by stays (4) to a ring (5) which has a ring-shaped bulge (7) on its interior side (6). The dia. of the bulge of the ring (5) is smaller than the dia. of the bulge (2) on the bottle neck, and the stays are evenly distributed on the upper edge (8) of the ring. The screw closure, the stays and the ring are all made from plastics material. Since the ring dia. is less than the neck bulge dia., the closure cap can't be removed without first breaking its connection with the stays. Thus the contents of the bottle cannot be tampered with without an indication being given that the closure cap has been removed.

Title: Remote-control transmitter for model - has receiver to check whether another model is using intended transmit channel
Inventor: KUSSMAUL SIEGFRIED
IPC: G05D1/00
Filed: 1980-10-02
Abstract: The transmitter contains a receiver (10) that can be switched-in instead of the transmitter (11). The receiver frequency is the same as that of the transmitter and is determined by the tuning circuit of the transmitter. A change in transmitter frequency automatically results in a corresponding change in receive frequency. The user can check before switching in the transmitter whether the channel he intends to transmit on is already occupied by the user of another model and therefore likely to lead to interference, i.e one user taking over the control of another model. This test can be performed automatically at periodic intervals.

Title: Structural panel
Inventor: WIEHOFSKY ALFRED
IPC: E04F13/04
Filed: 1981-06-15
Abstract: A description is given of a structural panel which can be produced rapidly and cost-effectively and comprises a base layer, which cannot be plastered directly, and a plaster carrier. The connection of plaster carrier/base layer is carried out by a foamed and bonding plastic which is applied only at certain locations, preferably in a bead-like or punctiform manner. In a preferred exemplary embodiment (according to Figure 1), a plaster carrier comprising a wire grid, which can be processed away from the roll, is fastened on a rigid-foamed-plastic base layer by a bead-like application of a polyurethane foam. By a special production method, it is ensured that the wire grid is spaced apart from the base layer at a distance which is necessary for good plaster clamping. A description is further given of structural panels and their production, in the case of which the plaster carrier is an expanded metal mesh or a fabric and the base layer consists of rigid foamed plastic or mineral-fibre mats. <IMAGE>
Patent DE-3132736-A1 (DE)
Title: Device for automatically producing a lifting force for the purpose of maintaining the level of a vehicle body, especially a motor vehicle body
Inventor: WALLENTOWITZ HENNING DR ING DI
IPC: B60G17/04
Filed: 1981-08-19
Abstract: The invention relates to a device for automatically producing a lifting force for the purpose of maintaining the level of a vehicle body, which is supported against vehicle axles by means of springs. The device is located between the body and the axle. It has a lifting device, actuatable by a fluid medium, and an actuating device interacting with the former, which with one part rests loosely on an abutment of the axle. On compression of the vehicle axle a lifting element of the lifting device is displaced by the actuating device in a direction opposed to the compression of the vehicle axle. For the lifting device to take effect, the actuating device is supported on the axle abutment so that the latter sets the reaction force necessary for level control against the additional forces generated. In the event of strong rebound, on the other hand, the actuating device can lift off from the abutment. In this way, protection of the axle components is achieved by the lifting device, which forms a vacuum-action spring, together with a wheel load adjustment on the outer cornering vehicle wheel which beneficially influences the handling of the vehicle when cornering.

Title: Hydraulic steering rack system
Inventor: LANG ARMIN ING GRAD
IPC: B62D5/22
Filed: 1981-06-05
Abstract: In a steering rack system whose servomotor (2) has non-balanced cylinder chambers (13, 16), that is to say the ratio of the piston faces to one another is approximately 1:2, the flow occurs from the servopump (4) to the control valve (3) via a pressure line (17) directly into the small cylinder chamber (13) and from there via a channel (18) into the rotatable valve housing (19) of the control valve (3). As a result, the compression medium passes by a portion of the toothed rack (8) and the pinion (7). As a result, the entire steering system, and in particular the rack seal (56), heats up uniformly and quickly. <IMAGE>

Title: Firing safety device with contact release for pneumatically driven tools for driving-in fastening means such as staples, pins, nails or the like
Inventor: BADE HEINZ EMIL
IPC: B25C1/00
Filed: 1982-02-16
Abstract: The firing safety device with contact release relates in particular to small tools with magazines which are supplied with driving-in means from the underside. To permit the opening and closing of such tools unhindered, a switch means specially suited thereto was necessary, which worked using a switch spring specially designed therefor. The switch spring encloses the front plate of the staple-ejecting channel in such a way that the staple-detaching plate, covering the channel from behind, on the movable underslide, permits unhindered opening of the magazine space for insertion of a staple bar. The switch spring acts at the upper end on a leaf spring which is mounted in a discharge lever and moves a switch shank stepwise. By pressing the tool against a workpiece with the discharge lever lifted, the system acts as a contact release. The reverse of the driving-in operation by means of the switch spring and the discharge lever, i.e. first pressing the tool onto a workpiece and then actuating the discharge lever, is the normal mode of operation of the tool. If the switch spring is not pressed in, the tool will still be prevented from firing even if the discharge lever is unintentionally actuated. <IMAGE>
