Inventor: EBERLE GUENTER
IPC: H04B3/54
Filed: 1980-12-06
Abstract: Heavy current, overhead grids are frequently used for transmission of telecommunications signals. An isolation position is intended for section repairs etc. without interrupting communications. The isolation concerns a suspended three-phase cable incorporating at least one optical fibre conductor. At both ends of the three-phase cable (1) at the isolation position, a through insulator (7,8) is secured on the transverse girder (4) of the respective mast. The optical fibre(s) (9) extends from one end of the three-phase cable to the other through both insulators. In their lower regions the latter contain relief catches for optical fibres, at the ends of the three-phase cable where the insulators are secured. At the ends, secured to the transverse girder, the threshold insulators may have chambers (13,14) for connection of optical fibres. The latter may be surrounded in the insulators by plastics, oil, or insulating gas.

Title: Pole lamination form for external rotor reluctance motor - gives flux paths with asymmetrical permeance to assist with run up
Inventor: BURGBACHER MARTIN
IPC: H02K19/10
Filed: 1980-12-31
Abstract: The rotor ring lamination has the permeance of the flux path between poles (M1,M2,M1',M2') modified by the addition of cut outs at the pole centres. These cut outs are asymmetrical between neighbouring poles, three slots (2,3,4) in one pole (M1,M1') and four (5,6,7,8) in the next M2,M2'). The resistance to quadrature fluxes is increased, which improves the machine performance, whilst at the same time the mechanical capabilities of the laminations are not brought below the acceptable minimum for safe operation.

Title: Step-ladder
Inventor: KRAUSE GUENTHER
IPC: E06C1/18
Filed: 1981-02-12
Abstract: Step-ladders which comprise at least two ladder parts, which have strings and steps and are connected to one another in an articulated manner and/or such that they can be displaced, have to have means which prevent the two ladder parts from spreading apart and absorb tensile and compressive forces. Said means comprise two struts which are articulated in each case on one string of a ladder part and, with their free ends, reach over the strings of the other ladder part and can be displaced along these. It has to be possible to fix said means simply and rapidly on the strings and, under any loading of the ladder, they have to absorb, absolutely reliably, the tensile and compressive forces acting on the strings and, moreover, they have to be simple to construct and thus cost-effective to produce. A step-ladder which fulfils these requirements has struts which, at their free ends, have a bore through which there engages one leg of a U-shaped bow which comes to bear on the front end surface of the string. The bow engages around the string, the other leg of said bow coming to bear on the opposite end side of the string and having an angled-off end engaging around the string on its inner side.

IPC: H01H9/04
Filed: 1981-02-20
Abstract: A fleece is employed for the distribution of casting resin over a component surface to be sealed. Prior to the introduction of the casting resin, pressure is applied on the fleece with a heated stamp in order to smoothen the fleece. Through increased temperature of the stamp, or through a solvent, the fleece can be readily cemented together with the component surface. It is thus ensured that the fleece rests uniformly on the entire component surface to promote a favorable distribution of the casting resin.
Patent DE-3106554-A1 (DE)
Title: Power supply unit
IPC: H02J9/06
Filed: 1981-02-21
Abstract: The invention relates to a power supply unit preferably having two series-connected galvanic elements and cells which emit an electrical voltage to at least one load. In order to obtain an extension in the useful life of the elements or cells while at the same time maintaining a predetermined minimum value, it is proposed to connect at least one further element or cell in series with the said elements or cells if the emitted voltage and/or the current flowing through the load falls below a predetermined minimum value. A reference unit and a control unit are advantageously provided for this purpose in order to carry out the specified additional connection via suitable switching means. If discrete electronic components are used, a zener diode is advantageously provided as the reference and control unit. The electronics can, of course, also be implemented using IC technology or even by means of microprocessors. In addition, the incidence of falling below the predetermined minimum value can be used to display a signal by means of special switching electronics. Furthermore, the changeover to a generator, especially a cycle dynamo, is proposed. <IMAGE>
Patent DE-3108698-A1 (DE)
Title: Box-type bed
Inventor: STROBECK ERNST
IPC: A47G9/02
Filed: 1981-03-07
Abstract: In order to save costs, a box-type bed has been devised, the inside transverse webs of which taper evenly on both longitudinal sides of the box-type bed until they disappear entirely. The box-type bed is therefore characterised in that the outside boxes on the longitudinal sides are lower and therefore require less stuffing. The longitudinal webs only taper slightly on both transverse sides of the box-type bed, so that the outer boxes on the transverse sides are characterised in that they are thicker than the boxes on the outer longitudinal sides, but are lower than and require less stuffing than the other inner boxes. To ensure that all boxes are accessible for stuffing, a required number of inner boxes receive cuts (open passage apertures) which are arranged in a radial fashion on the webs and are sealed off after stuffing. To permit the stuffing of the outer boxes, the outside seam remains open at the points which appear to be favourable, allowance being made for the passage apertures, and is closed up once stuffing has been completed. <IMAGE>

Title: Circuit arrangement for reducing the settling time
Inventor: JEHMLICH HANS DR
IPC: G03B7/08
Filed: 1981-04-02
Abstract: The invention relates to a circuit arrangement for reducing the settling time of differential amplifiers connected to a photodiode and having feedback via a logarithmation diode, the differential amplifiers forming the input stage of exposure measuring and control circuits of photographic cameras. It is the aim and object of the invention to shorten the settling time of such an input stage by means of a simple circuit which prevents the unwanted temporary blocking of the feedback diode as the cause for long settling times. According to the invention, the object is achieved by the fact that the feedback current flowing via the logarithmation diode and being used for balancing is reduced compared with known input circuits. <IMAGE>
Patent DE-3116906-A1 (DE)
Title: Central-locking system
Inventor: FEICHTIGER DIETER ING GRAD
IPC: E05B65/38
Filed: 1981-04-29
Abstract: The invention describes a central-locking system which has an acceleration switch and which has the advantage in comparison with the known systems of this type that the acceleration switch can be regenerated. This is achieved in that the pendulum of the acceleration switch is assigned pneumatic elements which, after the pendulum has been deflected out of its neutral position, bring the latter back into this again when the overpressure generated for automatic release in a pneumatic circuit is fed to the pneumatic elements. As a result, the acceleration switch can be used as often as desired, without having to be exchanged or be brought into the position of rest again by hand, as is the case in the known types. There is provision, furthermore, for the pneumatic elements to be arranged around the pendulum in such a way that, during any deflection, that is to say irrespective of the direction of the acceleration components occurring on the motor vehicle, the pendulum acts on one of the pneumatic elements, so that the pendulum is then also brought back into its neutral position again from any direction.

Patent DE-3133174-A1 (DE)
Title: Liquid-chamber wall
Inventor: BERNECKER STEFAN
IPC: B63C11/04
Filed: 1981-08-21
Abstract: The invention relates to a liquid-chamber wall system which is specifically intended for diving suits or for similar requirements of a pressure-tight, but movable, envelope. The purpose of the invention is to allow, for example, a diver to remain under atmospheric pressure even at great diving depths with high independent mobility. This object is achieved according to the invention in that an incompressible fluid is encased honeycomb-like by an inherently flexible, but inelastic, envelope in a multiplicity of small and miniature, ball-, pillow- or drop-shaped chambers not connected to one another (see drawing). This envelope web prevents displacement of the water chambers against one another. The incompressible filling water prevents a reduction in the system volume when the external pressure rises, and the inextensibility of the envelope material prevents substantial deformation of the filling water, which presses in the direction of the lower pressure. Mechanical deformation remains possible. Stiffening of the system is prevented by the flexibility of the material and by filling of the chambers under normal pressure. The wall can, to a small extent, expand and contract and settle. <IMAGE>
Patent DE-3139302-A1 (DE)
Title: Appliance for the advance planning and setting of dates
Inventor: SCHILLING HANS K
IPC: G09F7/02
Filed: 1981-10-02
Abstract: The date planning appliance has clamping strips (1a, 1b, 1c) which are subdivided along their upper edge into individual lamellae (7) by means of incisions (6). As a result, each lamella, when numerous individual markings (8) are inserted behind it, can be bent relatively sharply and independently of the other lamellae. The latter, even if they are immediately next to this lamella and, for example, exhibit only a single signal, exert a contact pressure thereon which is uninfluenced by the accumulation of the signals next door. As a result, any drop-out or displacement of such individual signals is avoided. <IMAGE>
