Title: Longitudinally sealed electric cable - has hydrophobic substances such as suspension of dielectric powder and oil between wire cores
Inventor: POLLE HUBERT DR RER NAT
IPC: H01B7/285
Filed: 1980-12-19
Abstract: The sealed cable sheath surrounds a core of plastics insulated conductors. The cavities between the individual strands, or between the core and the sheath is filled with hydrophobic substances. The latter are formed by a suspension of powder of high dielectric capacity and a high-quality dielectric oil, the latter being absorbed by the powder. Preferably, agents are admixed to the filling substances, which do not react with the oils used, such as small hollow spheres of plastics. Alternately, different powders of high dielectric constant may be used for this purpose, especially expanding considerably in the temperature range from 60 to 100 deg.C. The powders may swell when absorbing water. The mixing of the powder-oil suspension should take place shortly before filling into the cable core.

Title: Demountable shelf set and demountable shelf unit consisting of a plurality of interconnected shelf sets
Inventor: ULLMANN WALDEMAR
IPC: F16B12/32
Filed: 1981-01-29
Abstract: The invention provides a demountable shelf set or a demountable shelf unit built up of a plurality of demountable shelf sets, made of angular corner posts and rectangular shelves with a peripheral shelf trim which is bent downwards and is fixed by its respective corners in the hollows of the angular corner posts in a positive-locking manner. In this case, the angular corner post has a hollow profile whose hollow has a continuous slot through which a clamping bolt projects. The latter likewise passes through the edge of the shelf trim and, with a clamping nut being screwed on from the inner side of the shelf trim, allows the outer sides of the angular corner post and the shelf trim to be clamped flatly against one another with a clamping action direction oriented towards the corner edge of the shelf trim. It is thus achieved that the shelves can be adjusted infinitely variably in height and the shelf set obtains a structure which is greatly resistant to torsion such that additional reinforcing elements may be omitted. The shelf set is preferably used in the food industry, particularly in the bakery trade.

Patent DE-3119577-A1 (DE)
Title: Operating table with hydraulically movable table elements
Inventor: KRAFT GOTTFRIED ING GRAD
IPC: A61G13/02
Filed: 1981-05-16
Abstract: In an operating table (1) with hydraulically movable table elements, especially table board parts (8, 9) and a table column (3), and with a multiple-user control system (25) which projects on an extension arm into the working area of the operator and comprises a selection lever (24) for the individual adjustment functions, a solution is to be provided that permits control of an operating table with technically simple means and hence represents an economic solution that permits, in particular, a very substantial pivotability of the extension arm and is not restricted to a specific number of control functions. At the same time, simple means are to ensure one-handed operation, that is, the operator of the table should have to use one hand only for execution of the control function. This is achieved in that a mechanical control gear (31, 38) which acts upon a multiple adjustment valve (35) in the bottom region (2) of the standing column (3) of the operating table (1) is provided in the extension arm (23) for transmission of the control functions set via the selection lever (24). <IMAGE>

Patent DE-3203414-A1 (DE)
Title: Supercharger for combustion engines
Inventor: HEGEL HERBERT
IPC: F02B39/04
Filed: 1982-02-02
Abstract: The superchargers hitherto developed for combustion engines are driven by means of a turbine, which is driven in turn by the exhaust gases produced. The disadvantages are clear: that is 1. very high temperatures, so that very high-grade materials are necessary. This then makes the supercharger into a very costly unit and the costs of the supercharger very often exceed those of the engine to be supercharged. Only in this way, however, can the very high temperatures occurring be suitably countered, these often being so high that they cause the supercharger to glow. Since these high temperatures cannot be transmitted to the engine, an intercooler must also be fitted, which makes the entire system so costly and complex in the first place. These negative factors are overcome in the case of my invention in that this supercharger is driven not by an exhaust gas turbine but by a simple V-belt drive, by means of which rotational speeds of 40-60,000 rpm can easily be achieved. In order to be able to obtain the necessary charge air pressure, however, this supercharger would have to be designed correspondingly larger still, so that it could be readily accommodated in the engine compartment of a motor vehicle, since the charge air cooling, which also takes up a lot of space, would be dispensed with and charge air cooling is not necessary in this unit. A further advantage is that nowhere near such high-grade metals have to be used for the manufacture of this supercharger and hence the manufacturing costs could also be considerably reduced. This supercharger would therefore also not be confined to higher- specification motor vehicles but could also be fitted cost-effectively in low and mid-range cars. A further advantage of this supercharger is that the engine to be supercharged can be optimally supplied with the necessary charge air pressure even in the lowest speed range, which is not possible in the case of current superchargers since these begin supercharging only from a certain speed range upwards.

Abstract: The invention relates to a hydrostatic servo steering system with emergency source for mobile machines. The servo steering system is formed from a main circuit (1) and an auxiliary circuit (2). The steering unit (18) which is connected to the working spaces (8'', 9'') of the steering motors (8, 9) by means of control lines (19, 20) is connected to the primary source via a branch line (4') and a pressure line (4) of the main circuit (1) and the steering unit (18) is also connected to the emergency source (15) via a further branch line (4') of the pressure line (4). At the same time, the directional control valve (18'') which is connected to the working spaces (8', 9') of the steering motors (8, 9) by means of the working line (6, 7) is connected only to the primary source with the pressure line (4) of the main circuit (1). The directional control valve (18'') interrupts the connection of the pressure line (4) of the main circuit (1) to the tank line (10'') of the main circuit earlier before the directional control valve (18'') of the steering unit (18) disconnects the through connection of the pressure line (4) of the main circuit (1) to the tank line (10'') of the auxiliary circuit (2). In the connection described, the auxiliary circuit (2) forms a natural reserve of the main circuit (1). Only in the case of extremely large steering resistances is the auxiliary circuit involved in the energy transmission which is necessary for steering. <IMAGE>
