Near the bottom open end of support and arm there are mutually aligned stop faces (2,3,) for the rails. The support can consists of a guiding support (1) and an extension support (6) able to slide in relation to it. The latter is pref. guided in the open profile of the former.
Patent DE-3016223-A1 (DE)
Inventor: HARTMANN HANS
IPC: G01R31/11
Filed: 1980-04-26
Abstract: To locate faults in electrical lines (9, 10) by means of the pulse echo method, two pulse echo curves (3) of structurally identical lines are compared, one curve having been recorded by a faultless line and the other curve having been recorded from a line with a fault (F) to be found by means of a pulse echo measuring instrument (1) and stored by means of a signal storage device (15). To be independent of the specialist knowledge of an expert in the evaluation of curves, an evaluating device is specified which synchronously compares the two pulse echo curves to be compared or, respectively, the signal voltages and/or the time delays of these signal voltages, derived from these curves. In dependence on the signals to be compared exceeding predeterminable limit values, an error signal is generated, the transit time of the transmitted pulse from the start (A) of the line to the fault location (F) is determined and the fault distance (1F) is calculated and indicated. The width of the transmitted pulses (16) is preferably less than 2 ns, and the voltage used is lower than 60 V. The method specified is also suitable for fault location on high-voltage tubular gas-filled lines. <IMAGE>

Title: Electric conductor with seamless shrunk polyester sleeve - applied after stretch orientation and storage in concertina form
Inventor: GRAETZ REINHARDT
IPC: B29C63/42
Filed: 1980-06-30
Abstract: Electrical conductor has a seamless, shrunk-on sleeve of thermoplastics encasing it; the sleeve is of a multiaxially stretch-oriented polyester foil, shrunk onto the cable by releasing its inherent shrinkage stresses. Specifically, an electrical conductor is pulled through a hollow mandrel, on which the polyester foil is stored in concertina fashion; as the conductor advances leaving the mandrel, the polyester foil, gradually drawn from the concertina store, follows and loosely encases the conductor, joins it, advances axially with it and passes through a heating zone, where the hot-shrinkage tightly pulls the sleeves onto the conductor. The sleeve is subsequently cooled (20). Used for sheathing an electrical conductor in a seamless polyester tube which contains no plasticiser and has high mechanical strength.

Title: Line code reader - has polarising filter to suppress direct reflected light from shiny surfaces
Inventor: KUGLER ROLAND ING GRAD
IPC: G06K7/10
Filed: 1980-08-01
Abstract: This line code reader is designed to maintain high resolution even with very shiny surfaces. This is achieved by using a polarising filter in the optical system which suppresses direct reflected light but passes diffuse refelected light. A light source (2) illuminates the line code (8) via an optical system comprising a lens (3), a semitransparent mirror (6) followed by a polarising filter (10) and second lens (4). The reflected light has to pass again through the filter (10) but is then reflected by the mirror (6) and focused by a lens (15) on to the detector (13).

Title: Indicating light fitting - has hollow mirror reflector emitting non-parallel light beam in whose path is mounted lens for beam deflection in axial direction
IPC: F21V5/00
Filed: 1980-09-17
Abstract: The vehicle light fitting limits an axial main light beam and has a housing with a hollow mirror reflector, the light source being preferably mounted on the optical axis. At least at one side in the plane through the optical axis is provided a lateral light output aperture for emitting part of the light in a fan-shaped pattern. The hollow reflector projects a non-parallel light beam. In its light path is mounted a lens, focussing the reflector light into an axial main light beam. Preferably the reflector is parabolic, with the light source mounted between the focuss and the ridge of the reflector. The lens may be a condenser or a diffuser. If the reflector is spherical, the light source is mounted in its centre and the lens is a condensor.

Title: Control device for heating systems
Inventor: ANDERS HORST-GUENTHER ING GRAD
IPC: G05D23/20
Filed: 1981-03-16
Abstract: The invention relates to a control device for heating systems which has an electronic control loop to whose inputs there are applied a controlled variable which depends on the feed temperature of the heating medium and a reference variable which depends on the outside temperature, and to whose output a manipulated variable is applied which also depends on a desired variable (desired temperature). In order to achieve optimum control of the inside temperature (Tr), the system deviation (Xw) is formed from the desired variable (S) and a further reference variable (Fr) which depends on the inside temperature (Tr), and one reference variable (Fa) is evaluated by means of an optimization circuit (21); the output signal of the optimization circuit (21) leads to a change in an evaluation of one reference variable (Fa) in an evaluation circuit (24). The invention can be applied chiefly in heating controllers. <IMAGE>

Title: Beam generator system of a television tube or the like
Inventor: KRANZ THOMAS
IPC: H01J29/56
Filed: 1981-06-20
Abstract: A device having one or more magnetic pole pairs is fitted externally on the tube or in its interior in the neck region around the beam forming zone (SZ), which device is constructed in such a manner that the magnetic field generated (produced) by it substantially corrects for any eccentricity (caused by grid offset in the beam forming zone) of the electron beam in the main lens with respect to the optical axis. This results in an improvement in the sharpness characteristics in the north and south, as a result of the absence of flare. The invention can be used in television tubes. <IMAGE>

Title: Circuit arrangement for voltage and current stabilisation of a high-voltage generator

IPC: H02M3/337
Filed: 1981-09-11
Abstract: In the case of a circuit arrangement for voltage and current stabilisation of a high-voltage generator (10) for copiers which operate by means of a corona discharge, a comparator stage (11) is provided in order to implement an automatic transition between voltage and current stabilisation and for short-circuit current limiting, which comparator stage (11) compares a reference voltage (Uref) with a voltage (U1) derived from the output voltage (UA) of the high-voltage generator (10) and with a voltage (U2) derived from the output current (IA) of the high-voltage generator (10), in such a manner that, if the voltage (U1) derived from the output voltage (UA) or the voltage (U2) derived from the output current (IA) exceeds the reference voltage (Uref), it supplies an output signal to control an input voltage (UE) of the high-voltage generator (10) in the sense of stabilising the output voltage (UA) and the output current (IA). <IMAGE>
Patent DE-3137567-A1 (DE)
Title: Closing element for a shut-off slide valve
Inventor: MATTHES EKKEHARD
IPC: F16K3/12
Filed: 1981-09-22
Abstract: Shut-off slide valves are known, whose closing elements have wedge plates provided with sealing seats which are aligned to one another in the form of wedges. The wedge plates are supported on a central sphere and are coupled to one another by means of a bayonet closure located on the circumferential side of the sphere. Above the bayonet closure, the wedge plates have projections and undercuts which are used for attachment of the end section of the slide valve spindle, which end section is constructed like a hammer head. The disadvantageous feature with this type of construction is the high manufacturing cost, which results from the precise mechanical machining required to produce the bayonet closure and the welding work which is necessary as a result of the fitment of the bayonet closure to the rear surfaces of the wedge plates. A further disadvantage is the absence of a capability to readjust the wedge plates when the sealing seats are subject to wear. In contrast, a closing element is proposed according to the invention, whose wedge plates (6, 7) are hooked to one another by means of straight claw strips (26 to 29) which are arranged above and below the central supporting body (17). The supporting body (17) has a spherical end face (19) to compensate for angle inaccuracies and a flat end face (18) between which and the mating face (14) on the associated wedge plate (6) compensating discs can be inserted if reworking of the sealing seats (10) is necessary. The holder (3) for the hammer head end (2) of the slide valve spindle (1) is formed by strip-like projections (4) and groove-like undercuts (5) on the wedge plates (6, 7). <IMAGE>
