Patent DE-3336465-A1 (DE)
Title: Module for a high-temperature gas line
Inventor: STAUSEBACH DIETER DIPL ING
IPC: G21C1/00
Filed: 1983-10-06
Abstract: For high-temperature gas lines, for example for nuclear-power installations which are operated with helium at 950 DEG C and 40 bars, a design is proposed which has adequate thermal elasticity, allows rapid pressure equalisation in the event of a pressure loss as a result of a defect, avoids locally occurring destruction of the insulation (5), which is in the form of fibre, as a result of fulling caused by temperature fluctuations, and prevents the origination of relatively large convection flows, by splitting the insulation by means of separating walls (41, 42). The structure consists of a pressure-tight outer tube (1), an inner tube (2) which is essentially constructed from folding bellows compensators (21, 22) which in some circumstances may be perforated, and thermo-sleeves (3) which connect the two parts together. The flow is guided by means of a special tube (8) which is mounted on the inner tube on only one side. The fabric layers (61) with a large and (62) with a small mesh size, which cover the outside of the compensators, prevent the discharge of insulating fibres, while at the same time facilitating the gas flow which results in the pressure equalisation. The module of length X is connected to other pipelines of this type, of any desired length. <IMAGE>
Patent DE-3337241-A1 (DE)
Title: Fan for producing wind or for cooling excessive temperatures
IPC: F04D25/08
Filed: 1983-10-13
Abstract: The fan for producing wind or for cooling excessive temperatures is intended for direct and personal use by persons who are away from their usual premises and do not have any power mains supply available (for example train compartment etc.), but wish to protect themselves from or to alleviate excessive temperatures or their unpleasant attendant manifestations (including perspiration). The fans currently available commercially are fundamentally unsuitable for this. On the one hand they are too large and bulky - on the other hand they do not have an independent power supply, that is they are tied to buildings. The fan submitted in the present application, however, fulfils these substantive requirements. It is of light, handy design and is equipped with built-in and independent power supply facilities. These independent electrical energy sources in particular comprise an accumulator, with a charging device and a mains connection, a storage battery, also with a charging device and a mains connection, a dry battery and last but not least solar power on the basis of the photo-voltaic effect.
Patent DE-3343759-A1 (DE)
Title: Tool holder on hand-operated devices, in particular screwdriver devices
Inventor: CASEL HERBERT
IPC: B25G3/22
Filed: 1983-12-03
Abstract: Tool holders (6) which are arranged on the free end of the rotatable drive spindle (4) of a hand-operated device, for example a ratchet screwdriver, have a tool-receiving sleeve (7) which is made of a non-magnetisable material, has a polygonal insertion opening (9) for the screwdriver bit (10) and contains a permanent magnet behind that.   In order to increase the holding force of this permanent magnet without increasing the constructional dimensions of the tool holder (6), the permanent magnet is designed as a pot-shaped magnet (11, 12), the annular wall part (11) of which extends the polygonal insertion opening (9) to the rear, and against the base (12) of which the inserted screwdriver bit (10) bears. The pot-shaped magnet advantageously consists of a permanently magnetic ring (11) forming its wall part and a disc (12) of magnetisable material forming its base and bearing against the rear side of the ring (11), it being possible for a circular-cylindrical permanent magnet (13) to also be arranged behind the base disc (12), which circular-cylindrical permanent magnet (13) bears with the same magnetic polarity as the magnetic ring (11) against the base disc (12). <IMAGE>

Patent DE-3609404-A1 (DE)
Inventor: WINKELMANN SIEGFRIED
IPC: F16D65/18
Filed: 1986-03-20
Abstract: Through certain measures concerning arrangement and dimensions, an electromagnetic (21) permanent magnet (20) coupling (5) has been devised, whose power equilibrium in its closed state does not trigger any change of position when power is cut off; at the same time, the closing pressure of the coupling is so reduced that the latter can open at an unacceptable torque. Opening or the holding open of the coupling can be triggered with counterpolarity by way of a special electrical circuit arrangement by means of a short power impulse (33). If this power impulse is reduced for example by way of a current divider, the opening of the frontal gears of the coupling can be effected only partially, so that infinitely variable changeability of the opening torque of the coupling can be achieved. This type of coupling is therefore expecially suitable for motors which, during of cut-off or power breakdowns must maintain their exact adjustment but at the same time can be secured against unacceptable torque overloading.
