Filed: 1988-01-20
Abstract: Doors locks can be provided with at least one locking element (3) mounted displaceably in the lock-case housing (1) and partially extendable therefrom by spring force, and with an auxiliary latch (11) which cooperates with the latter and which, when the door wing assumes the closed position, is to be pressed into the lock-case interior counter to a spring effect by an actuating element located on the fixed-frame side and thereby triggers a switching function releasing the locking element (3). In order to prevent an inadvertently premature release of the auxiliary latch (11) with the door wing opened, a safety device triggering the switching function of the auxiliary latch (11) only with the door wing is closed is provided. This can consist of a second auxiliary latch (12) or else also of a pair of permanent magnets, of which one is installed in the auxiliary latch and the other correspondingly on the fixed-frame side. <IMAGE>

Abstract: In the transmission of information via connection paths with switching centres, the feedback circuits which occur in the hybrid circuits cause a serious problem. Substantial demands are imposed on these and on the balancing circuits. The invention overcomes these deficiencies by forming quasi-4-wire circuits in such a way that alternating coding currents of different frequencies and/or frequency positions and/or phase angles are provided for both transmission directions and, if both transmission directions need to be separated, filters with high blocking attenuations for the opposite direction are provided, the phase angles preferably being produced in digital form.

Title: Radial piston pump, in particular for motor-vehicle brake systems with ABS
Inventor: BUDECKER LUDWIG
IPC: F04B53/10
Filed: 1988-03-17
Abstract: The invention relates to a radial piston pump for a motor-vehicle brake system. Brake systems of this kind are intended to be as silent as is possible and by division into various circuits are intended to have a plurality of safeguards. Moreover, the object consists in being able to adapt the damping of the pressure fluctuations caused by the pump piston as closely as possible to the requirements of the operators. To this end, the invention proposes damping chambers assigned in a fixed manner to the individual ducts. These damping chambers can be combined with the associated outlet valves to form an exchangeable constructional unit (damping chamber valve) which can be matched to requirements. Advantageous developments of the invention are concerned with a suitable design of the damping chamber and the travel routes of the pressure fluid within the constructional unit. <IMAGE>

IPC: F16L55/128
Filed: 1988-03-17
Abstract: Method for sealing a cable duct which consists of a cable guiding segment in the underground part of a house wall and buried cable duct moulded bricks which project outwards. A longitudinal plug is inserted into the cable duct as far as a sealing position in the region of the cable duct moulded bricks with the help of a releasable operating rod from the inside of the house wall, which plug has sealing elements which can be expanded against the cable duct wall with the help of the operating rod. The sealing elements are tensioned and thereby extended by actuating the operating rod in the sealing position of the plug. The operating rod is then released from the plug and the operating rod can be withdrawn. A device for implementing the method is also provided. <IMAGE>

Patent DE-3830477-A1 (DE)
Title: Forceps for the extraction of teeth
Inventor: RUESCHER-LAMBRECHT HARRO DR
IPC: A61C3/14
Filed: 1988-09-08
Abstract: Forceps for the extraction of teeth having two double-armed levers which are connected to one another via a pivot bearing and in which one pair of adjacent arms is designed as handles and the other pair is designed as jaws for gripping and holding the tooth. The jaws can be pivoted over a limited angle relative to one another about an axis which extends essentially at right angles to the jaws and at right angles to the pivot bearing. In this way, the jaws can move laterally toward one another and thus adapt themselves laterally to the anatomical shape of the tooth, e.g. engage in a simple manner in bifurcations of a tooth without it being possible for any lateral forces to act upon the tooth which impair adhesion of the jaws on the tooth or the tooth itself and may break the dental roots (radices) (drawing: Fig. 2). <IMAGE>

Abstract: A device for the continuous injection of a mixture of fuel and carrier air into the intake ports (7) assigned to the individual cylinders of a mixture-compressing internal combustion engine (1) is described, which has an injection valve (11), which meters the fuel in injection lines (13), separately assigned to the individual cylinders, as a function of the operating condition of the internal combustion engine. In addition an appliance is provided for the feeding and distribution of the carrier air to the injection lines (13) leading to the injection points in the intake ports (7) of the internal combustion engine. In order to ensure an optimum fuel injection with good preparation and short response times to load changes of the internal combustion engine, it is proposed that the injection lines (13) each have a first port (20) for delivery of the fuel and at least one second port (21) separate from the first port, for delivery of the carrier air. At the same time it is proposed that the first port (20) open into the second port or ports (21) immediately upstream of the injection point in order to form a mixture of fuel and carrier air to be injected into the intake port (7). <IMAGE>

Title: Device for transporting a preferably multi-layer web of thermoplastic
Inventor: MATTIEBE GUENTER
IPC: B65H23/28
Filed: 1989-03-14
Abstract: A device for transporting a preferably multi-layer web of thermoplastic, consisting of a pair of transporter rollers which delimit a conveyor gap, and in which each roller is provided with annular grooves, and of two stripper rakes which are secured in the frame and whose tines engage in the annular grooves, and of which at least one is mounted movably and activates a switch shutting-off the roller drive when the web moves this stripper rake out of its normal position due to a blockage or jamming, is to be further developed in such a way that the switch is activated even when only slight blockages occur in the web. This object is achieved by virtue of the fact that the stripper rake (11, 7; 12, 8) is guided movably in the transport direction of the web (9). The stripper rake activating the switch can be moved with very much less force if it does not pivot, but instead is moved in the transport direction of the web. The device according to the invention advantageously responds much more sensitively to blockage of the web than do devices of the prior art. <IMAGE>

Patent DE-3909437-A1 (DE)
Title: Magnetic tape apparatus with automatic level setting
Inventor: THANHEISER WILHELM
IPC: G11B5/035
Filed: 1989-03-22
Abstract: In magnetic tape apparatuses with compander systems, the recording level must be set such that the level at the input of the expander corresponds to the level at the output of the compressor. This setting takes place in the factory and is not always at an optimum, since the magnetic tapes have different sensitivities. The level setting therefore always remains a compromise. The invention achieves the effect that the level setting takes place automatically after each time a magnetic tape is loaded and when recording onto it. For this purpose, in a magnetic tape apparatus which has a tape monitoring capability, the signals taken upstream of the recording amplifier and downstream of the reproducing amplifier are fed to a comparison circuit, a control voltage being obtained from the comparison and fed to the control input of a controllable amplifier arranged in the recording channel. Level adaptation in magnetic tape apparatuses with compander systems.
