Patent DE-3524077-A1 (DE)
Inventor: ESTORFF ECKART VON DIPL ING
IPC: B60G11/10
Filed: 1985-07-05
Abstract: A leaf spring to be clamped between a saddle of the vehicle axle and a clamping plate by means of two connecting elements spaced from one another in a longitudinal direction has an elongated spring member extending in the longitudinal direction, and is composed of a fiber-reinforced duro-plastic synthetic material. At least two supporting plates each have a length exceeding the length of the saddle or of the clamping plate, and each have an inner region located inside the connecting elements, and an outer region located outside the connecting elements. One of the supporting plates is located at one side of the spring member, so as to be arranged between the spring member and the saddle, the other of the supporting plates is located at the other side of the spring member so as to be located between the spring member and the clamping plate. The supporting members abut against the spring member in the inner region, and pressure cushions composed of a rubber-elastic material are each located between a respective one of the supporting plates and the spring member in the outer region.

Title: Spray process for the chemical determination of free halogen and pseudohalogen ions, in particular chlorine ions, on surfaces or fracture surfaces of materials
Inventor: SCHOEPPEL KLAUS DIPL ING
IPC: G01N31/22
Filed: 1986-02-19
Abstract: The invention achieves the object of detecting free halogen and pseudohalogen ions, in particular chlorine ions, on the surface or fracture surface of porous and non-porous materials. For this purpose a special spray gun made of corrosion-resistant material is used, with which silver nitrate, potassium chromate and optionally citrate buffer solution can be applied in sequence in the form of aerosols to the material surface. This results in precipitation of silver chloride in regions containing free chlorine ions. The other regions are coloured brown or reddish brown (carbonated concrete region). Subsequent action of artificial or natural UV light causes the colour of the AgCl-containing region to change to grey. The residual region changes to a black colour after a longer period of time.

Filed: 1986-06-06
Abstract: A triple-radius steering gear system (1 plus 2) in which are located a hydrostatic partial gear (1) and a mechanical partial gear (2). A zero-shaft (21) actuates, via a summation gear (3) and output shafts (34), the track-laying wheels of a track-type vehicle in order to achieve a curved trajectory. For this system, in the first radius range (RI) only the hydrostatic partial gear (1) is operative, in the second radius range (RII), the hydrostatic (1) and mechanical (2) partial gears are operative, and in a third fixed radius (RF) only the mechanical partial gears (2) are operative, so that the rotation speed of the zero shaft (21) ensures, in a first and second radius range (RI and RII), a progressive steering action, and, in the third radius range a steering action with a fixed small radius (RF). The mechanical partial gear (2) is a planetary gear system with three simple wheel sets (23, 24 and 25), which preferably possess the same sun-wheels and same internally geared wheels.

Title: Self-locking feeding enclosure for pigs
Inventor: EICHHOLZ HEINZ
IPC: A01K1/02
Filed: 1986-06-19
Abstract: The invention relates to a self-locking feeding enclosure for pigs, having a pivotable rocker which is mounted approximately centrally on the side walls of the box, can be arrested in the closed position by means of a locking bar and thus close off the rear enclosure entrance, and having at least one automatically closing side-wall swing door, as enclosure exit, which is arranged on the trough side and can be opened from the interior of the enclosure. The enclosure is characterised by a lever (6) which is inevitably actuated by an animal entering into the enclosure (1) and/or located therein, which, via an intermediate member (5) transmitting tension and/or thrust forces, effects, on actuation, a movement of the locking bar (4) of the rocker locking mechanism in the closing direction, and which, in its basic position, positions the locking bar (4) in the open position. <IMAGE>
Patent DE-3700744-A1 (DE)
Title: Ventilation device for roof spaces
Inventor: WILLIAN ROBERT PETER ANTHONY
IPC: E04D1/30
Filed: 1987-01-13
Abstract: Ventilation devices for roof spaces conventionally comprise a pipe which passes through the roof ridge and is covered by a wind-protection cap. Said devices detract from the aesthetic appearance of the roof and are susceptible to disruption in strong winds. The object of the invention is to integrate the ventilation device into the form of the roof such that it is unobtrusive and ensures disruption-free ventilation. The ventilation device has an outer form which is a simulation of a ridge tile and, by forming connection pieces on the end sides, it can be arranged in a row with the normal ridge tiles. Air exchange is ensured by lateral openings, the device being closed at the top so that wind, rain and snow cannot penetrate into the air duct. Use in the ridge tile of roofs of buildings.

Title: Method and arrangement for determining actuator travel end-positions of an actuator
Inventor: GRIEB HERBERT DIPL ING
IPC: G05B19/40
Filed: 1987-08-12
Abstract: An actuating device contains a position transmitter (DPG, VRZ) connected to the actuator (VT). To determine the actuator travel end-positions of the actuator (VT), the actuator is displaced first in one direction and then in the other direction, until a control unit (SL) connected to the position transmitter (DPG, VRZ) in each case determines a standstill. The position signals emmitted here by the position transmitter (DPG, VRZ) are those of the actuator travel end-positions. The main field of application of the invention is actuators. <IMAGE>

Title: Electrical fuse, especially an axial miniature fuse having a plastic moulded body, and a method for producing a fuse
Inventor: MONTER JOHN MICHAEL
IPC: H01H85/045
Filed: 1987-08-28
Abstract: An electricial fuse and a method for its production. The fuse has axially aligned conductors (5) and a fuse wire (1) in a cylindrical bush (2) which is held at its ends by caps (3) which, for their part, support the conductors (5). This fuse body is coated or extrusion coated over its entire length by an adhering insulating coating of plastic (7). Increased moisture resistance and increased mechanical strength are achieved, while precise conformity with the coating thickness is ensured at the same time. The hot plastic for the insulating body (7) melts the solder joints during its production so that scarcely any fuses having a high resistance and none with a conductor interruption are produced. Furthermore, the short-circuit current behaviour has been considerably improved in comparison with known fuses having coatings (Figure 2). <IMAGE>

Abstract: In the case of this module, optical waveguides which are in the form of strips (stripes) and consist of doped silicon dioxide are arranged on a silicon substrate, of which optical waveguides a straight branch connects the transmitting diode to the transmission fibre, while a curved branch which is coupled to the straight branch is passed transversely into a trench, which is etched in a V-shape, of a silicon-dioxide layer region which is provided on the substrate. A mirrored trench wall is used for deflecting the incoming optical signals onto a light-sensitive surface of a receiving diode component which covers the trench and is in the form of a plate.

IPC: D06B23/26
Filed: 1988-03-07
Abstract: The invention relates to a method and appliance for continuously measuring and controlling the loading of textile material with aqueous ionogenic agents and to the application thereof in sizing processes and is designed to provide a process for continuous direct measurement of the loading of textile material with aqueous agents, i.e. those dissolved or dispersed in water, which process is not only free of error sources of indirect measurement methods but which also operates sufficiently quickly to be able to make use of the measured values, if required, for correcting deviations from the nominal value (setpoint) in the input parameters of the process, and thus for process control. According to the invention it is proposed, after separating excess treatment or washing liquor from the textile material, to measure, with the aid of electrodes which are mounted so as to be insulated with respect to one another and are in intimate contact with the moist textile material, the ion conductivity of the moist textile material web situated between the electrodes and to utilise the measured values for process control purposes.
