IPC: H01R4/64
Filed: 1986-12-16
Abstract: The cable ducting has a metallic ducting section, preferably produced from aluminium, in which is constructed an earthing duct (20). The latter has a duct space accessible via a longitudinal slot (22). A metallic connecting piece (30) is provided for the connection of a protection conductor. This is attached by means of a screw (36) in the region of the earthing duct (20), this screw at the same time being used for the electrical contact with the earthing duct (20). The threaded shank of the screw either has a non-round cross-section with a minimal shank width, which is smaller than the unobstructed duct width of the longitudinal slot (22) and with a maximum shank width which is larger than this duct width, and/or the threaded shank (40) tapers in its longitudinal direction starting from a region of relatively large diameter in the vicinity of the screw head (38) to a region of relatively small diameter at the free end of the shank (40). <IMAGE>

Title: Barrier
Inventor: WIELAND WINFRIED
IPC: E01F13/06
Filed: 1987-12-21
Abstract: The invention relates to a barrier having a U-shaped holder (5) which is pivotable about a horizontal shaft (4) and is intended for receiving a barrier beam (3) between the two legs (7) of the holder, the holder being open perpendicularly to the pivoting plane of the barrier beam. It is the object of the present invention to provide a barrier of the said type in which, when an unpredicted high force is applied to the barrier beam perpendicularly to its pivoting plane, for example when unintentionally or intentionally travelling through the barrier beam, although the latter can tilt out of the holder it cannot be completely detached from the holder. According to the invention, a barrier of the type mentioned is proposed, which is characterised in that catch elements (9, 10), passing through openings (11, 12) in the barrier beam, are arranged between the legs (7), spaced apart from one another in the longitudinal direction of the holder (5). <IMAGE>
Patent DE-3744010-A1 (DE)
Title: Compensating reservoir
Inventor: SCHORN MICHAEL
IPC: B60T11/26
Filed: 1987-12-24
Abstract: What is proposed is a compensating reservoir for a hydraulic brake system, with a threaded cover which sealingly closes a filling connection and which has a ventilating bore, and with a valve arrangement arranged in the threaded cover, for compensating the pressure prevailing inside the reservoir, which valve arrangement is formed by a sealing seat opening or shutting off a connection between the ventilating bore and the inside of the container and closable by means of a closing body. In order to specify a compensating reservoir of this type, in which, at the same time as an increase in its operating reliability, an escape of brake fluid is safely prevented by the use of simple and cost-effective individual parts, the invention provides for guiding the closing body axially in the region of the sealing seat and for the closing body to be actuable by means of a buoyancy body movable to a limited extent in the closing direction. <IMAGE>

Patent DE-3806353-A1 (DE)
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/08
Filed: 1988-02-27
Abstract: Impact expansion dowels are known for insertion in undercut drilled holes in masonry, in which an expansion sleeve is pushed onto an expansion body supported on the base of the drilled hole when impacts are applied. The expansion region of the expansion sleeve in this case engages in the undercut of the drilled hole in a positively locking manner. In order that a tensile force applied to the expansion sleeve does not pull the expansion sleeve off the expansion body, the expansion body has a shank with a locking profile which engages into a corresponding locking profile of the inner hole of the expansion sleeve. In the region of the locking profile, the expansion sleeve is slotted and is thus designed to be elastic radially. <IMAGE>

Title: Electric power steering system
Inventor: OSHITA SAIICHIRO
IPC: B62D5/04
Filed: 1988-05-24
Abstract: An electric power steering system is indicated which comprises a motor which is operatively connected to a steering system in order to reduce the steering force which needs to be applied. The system is provided with a torsional moment sensor in order to sense the torsional moment which is produced in the steering system during steering. A supporting signal and an auxiliary supporting signal are produced in response to the output signal of the torsional moment sensor. Detection means are provided in order to detect whether the amount of fluctuation of the torsional moment moves in an increasing or decreasing direction and in order to produce a direction signal as a function of the detected direction. If the direction signal which represents the amount of fluctuation of the torsional moment in a decreasing direction is produced, the auxiliary supporting signal is reduced in size so that a composite supporting signal consisting of supporting signal and auxiliary supporting signal also decreases.

Filed: 1988-08-30
Abstract: The invention relates to a container lid (2) for a compensation container for a hydraulic brake system which tightly closes a filling nozzle and has an aeration and venting hole (5) for compensating the pressure prevailing inside the container. To improve the legibility of the warning instructions for the viewer on brake and clutch fluid containers, the legibility of the instruction in the direction of view of the viewer is facilitated by means of a rotatable centrally symmetrical arrangement of a separate disc (1) on the container lid (2). The good legibility of the instruction is intended to rule out incorrect operation in order to avoid serious damage to the hydraulic system. For easy assembly and alignment of the disc (1) on the container lid (2), the disc (1) is provided in the centre with two half-moon-shaped catch segments (4). <IMAGE>

Title: Method for controlling the circulation pump of a heating installation
Inventor: ABEL HELMUT
IPC: F24D19/10
Filed: 1988-11-12
Abstract: To reduce an excessively high condensate formation during the start-up of a boiler, the circulation pump should be switched off until a desired value is reached and then initially operated at a variable delivery rate. The variation of the delivery rate can be achieved by varying the rotational speed. This rotational-speed control is effected by means of a PI controller as a function of the undershooting of the desired value, a small difference resulting in a higher rotational speed than a large difference.

Title: Process for taking air in soil and for taking ground water as well as for determining the range of an air-in-soil suction installation
Inventor: FORSTER FERDINAND
IPC: G01N1/22
Filed: 1988-12-13
Abstract: For taking samples of air or water in soil and for the quantitative determination of the range of an air-in-soil suction unit, one or more probes are introduced permanently into the subsoil and sealed off from each other as well as from the atmosphere, by which means it is possible to undertake repeated measurements at various levels, without having to sink holes anew. For taking samples, the air-in-soil or, if necessary, water are transferred by means of the probe into a suitable sample holder, which is subsequently closed in an airtight manner. The range of the air-in-soil suction unit can be determined by the quantitative measurement of the underpressure present on the respective probe.

Title: Hold-down for shears, in particular billet shears
Inventor: MEINHARDT WOLFGANG
IPC: B23D33/08
Filed: 1989-04-10
Abstract: The invention relates to a hold-down for shears, in particular billet shears for cutting off bar and section material with a blade slide which can be actuated by means of crank or eccentric drive. The hold-down consists of a hold-down piston (6) which can be acted upon by pressure oil and is mounted displaceably in the vertical direction in a hold-down cylinder (5) fastened to the frame (1) of the shears.
