Title: Self-locking belt retractor especially for passive safety belt systems in motor vehicles
Inventor: BUTENOP KLAUS DIPL ING
IPC: B60R22/41
Filed: 1984-11-14
Abstract: In a self-locking belt retractor especially for passive safety belt systems in motor vehicles having a belt winding shaft mounted in a casing and an idle blocking element which is eccentrically mounted on one end of the shaft, collides with stops fixed to the casing as a result of radial deflection controlled by a belt band-sensitive and/or vehicle-sensitive blocking system and in so doing blocks the belt winding shaft, to which end the blocking element is coupled to a plate cam which has external toothing and which on the one hand can be blocked by a spherical sensor as a vehicle-sensitive system and on the other hand has a rotatably mounted, spring-loaded balance weight which interacts with a control lever as a belt band-sensitive system, the control lever being pivotable into a toothing formed on a bearing socket, the problem is that the belt drawing-out movements which are automatically carried out by the passive safety belt system can lead to blocking of the belt retractor, in so far as the belt band-sensitive and vehicle-sensitive blocking systems formed in the belt retractor respond. To solve the problem, it is proposed that a control device (25, 27, 28), which is activated by a control signal coming from the vehicle, be included in the belt retractor for connection and/or disconnection of the belt-band-sensitive blocking system (12, 13, 14, 16) and the vehicle-sensitive blocking system (12, 20, 19, 17) respectively to or from the plate cam (12). <IMAGE>

Title: Electrical DC voltage converter system
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H02M3/18
Filed: 1985-08-14
Abstract: A more far-reaching innovation has been achieved on the electrical DC voltage converter system of a capacitive type. The changeover switch which is used last in the case of integrated software, has eight poles or four male contacts, is linear or rotating and makes it possible to control milliards (thousands of millions) of integrated capacitors is given two further changeover male contacts or four changeover contacts. This results, not only as in the past during use as a high-voltage power source on particle accelerators, the converter efficiency of the multiring types becoming virtually 100%. The innovation generalizes the low-heat capacitive converter system described in the case of this high useful effect virtually 100%, even to DC high-power transmissions. In this case, it is advantageous that it can have only two lines, instead of three as in the past, and that it can have voltages up to gigavolts instead of only kilovolts to megavolts. The possibility for further innovations is indicated, specifically to further changeover contacts, whose use is provisionally under protection.

Title: Recooling apparatus for a liquid-metal-cooled nuclear reactor
Inventor: DUMM KONRAD DIPL ING
IPC: F28D7/02
Filed: 1985-10-28
Abstract: An air cooler for the residual-heat discharge cooling circuit of a liquid-metal-cooled nuclear reactor. The heat exchanger arranged at the bottom of a tower (1, 3) consists of a feedline (8), of an upper collector (9), of helically designed tube bundles (11), of an intermediate collector (21) serving, if appropriate, for equalizing the heat transfer between the inside and outside, of a lower collector (14) and of an outlet line (15), and is arranged in a casing (4) which is provided with heat insulation (5). In normal operation when, with full cooling, the coolant would freeze, the heat discharge is reduced by the closing of flaps (16, 18) having adjustable slots (17). If required, the flaps can open by gravity, that is to say without external energy. An air gap (6) between the tower and casing ensures that an additional cooling flow protecting the concrete of the tower is generated. <IMAGE>

Title: Method for the gentle heating of foodstuffs, stimulants or medicaments and similar products
Inventor: DALLINGA HELMUT
IPC: A23L3/10
Filed: 1986-03-03
Abstract: The invention relates to a method for the gentle heating of foodstuffs, stimulants or medicaments and similar products by means of a heating medium and the packaging for the product, in order to carry out the process. It is known that the flavour quality of such a product and its treatment can be improved if the product, during heating, is exposed to a pressure which is greater than the vapour pressure of the heating medium, required for heating the product, at the highest occurring temperature thereof. The object of the invention is to preserve the favourable effects on the product and to find an appropriate packaging in order to realise this. To achieve this, it is proposed to heat the product, portioned in an air-tight packaging, and thus to expose it to an adjustable temperature-dependent working pressure which is applied to the packaging and is above the vapour pressure of the heating medium, required for heating the product, at the highest occurring temperature thereof, preferably above this by more than 2 bar.

Title: Fixing apparatus for a basketball hoop
Inventor: PICHERT KARL
IPC: A63B63/08
Filed: 1986-04-01
Abstract: In the fixing apparatus, in which a piece (1) which is to be screwed on and a continuation piece (5) are held together articulated on one another via a horizontal axis (4), the basketball hoop (21) can be bent down against the force of a spring. In this arrangement it is desirable for the bending-down of the basketball hoop to be enlarged in terms of angle but without the target board being at risk as a result of the springing-back of the basketball hoop. This is achieved in that the basketball hoop (21) is held by means of a spring latch (17, 19) in the horizontal position and can be tilted downwards through at least 45 DEG , overcoming the spring latch, and a tension spring (14), when the basketball hoop (21) is horizontal, engages on the same side of the axis (4) firstly on the piece (1) which is to be screwed on and secondly on the continuation piece (5). A substantially enlarged and thus clearly visible downward tilting of the basketball hoop occurs without the target board being put at risk by the springing-back of the basketball hoop. <IMAGE>

Title: Vane adjusting gear for adjusting a speed under load
Inventor: NIEBUHR UWE
IPC: F16H29/12
Filed: 1986-04-19
Abstract: Vane adjusting gear for adjusting a speed under load, in which there is mounted about an adjustable eccentric a rotatable holding ring, on which on one side vanes are mounted resiliently movably with a bolt and engage in the manner of a spring lock in a toothed ring connected to the housing and on the other side vanes engage in a toothed ring connected to the output shaft. As a result of eccentric movement of the holding ring, the vanes are set into a continuous inclined position and thus cause a rotary movement to result on the output shaft. A speed which has been entered can thus, according to eccentric deflection, be lowered to a standstill or regulated to any speed entered under full load.
