Patent DE-4223488-A1 (DE)
Inventor: KATSOHI DESPINA DR MED
IPC: A61N5/10
Filed: 1992-07-17
Abstract: In radiation therapy for breast cancer, the use of compensating devices individually adapted to the patient is known in order to ensure a uniform target volume in a planar arrangement for the radiation regardless of the outward shape of the body to be irradiated. Individual adaptation, however, is time-consuming and expensive in preparation and removal, since these devices cannot be re-used. The compensating device of the invention avoids these drawbacks in that a pourable or easily deformable material is used as a filler which is embedded in a gas or airtight casing which has a defined dimensionally stable surface region at least on the side towards the radiation source but is easily deformable on the side towards the body. The compensating device is especially suitable for the irradiation of breast cancers.

Title: Introducing gold@ or platinum@ contact wire into thermoplastic housing of electrochemical gas sensor - passing current through wire to heat to temp. above melting point of plastic, pressing into housing to required position and fixing fluid-tightly by cooling
Inventor: KUEHN UWE
IPC: H01R43/00
Filed: 1992-08-27
Abstract: The sensor housing (1) is made of thermoplastic and a contact wire (2) is heated to a temp. above the melting point of the plastic. With melting of the plastic, the wire is pressed into a predetermined position in the housing. It is then allowed to cool so that it is fixed in the housing in a fluid-tight manner. The contact wire (2) is heated by having a current passed through it. During introduction into the sensor housing (1), the wire is tightly stretched and is pressed into position in a radial or axial direction. USE/ADVANTAGE - Eg for inserting platinum wire into polypropylene or polythene housing, or gold wire into polyamide housing. Only one work process is necessary to introduce contact wire into sensor housing.

Title: Thin film windshield heater for aircraft
Inventor: GAGE GRAHAM FREDERICK
IPC: H05B3/84
Filed: 1992-11-03
Abstract: The electrical windshield heating system includes a windshield structure having an electrical heating film embodied in it, and a circuit for powering the heating film. The circuit comprises a converter (3, 7, 8) which generates a relatively high DC voltage supply from a relatively low DC voltage source.

Inventor: ENNENGA LUITJEN DIPL ING
IPC: F41A23/20
Filed: 1993-02-24
Abstract: In the case of a cross-country vehicle (10) (off-road vehicle) having a driver's cab (13) and a cargo area (14), and having an apparatus (15) which is mounted on the cargo area (14) and overhangs the driver's cab (13), especially for anti-aircraft defence, the apparatus (15) is arranged on a platform (23) in order to ensure air-transportability and good driving characteristics for the vehicle despite the apparatus (15) being fitted on it, which platform (23) is held on a framework (24), which is firmly anchored to the cargo area (14), such that it can pivot about a pivoting axis (pivoting shaft) (25), which extends transversely with respect to the vehicle longitudinal axis, from an approximately horizontal in-use position located essentially parallel to the cargo area (14) underneath the roof contour (26) into an approximately vertical transportation position, extending along the rear wall of the driver's cab, and vice versa. The pivoting axis (25) is arranged such that, when the platform (23) is in the transportation position, the centre of gravity of the apparatus (15) is located in front of the vehicle rear axle (12) and as close to the cargo area (14) as possible. <IMAGE>

Title: Method and apparatus for the operation of a heat exchanger-type or room-air-type air conditioning apparatus
Inventor: MICHALAK BERND
IPC: F24F3/044
Filed: 1993-02-25
Abstract: Heat exchanger-type or room-air-type air conditioning apparatuses can be run in purely outside-air mode, in purely circulating-air mode or in mixed mode. In each case, construction elements are required for the heat exchange in order to be able to make corrections in the event of relatively large temperature differences between outside-air temperature and room-air temperature. The associated construction elements constitute flow resistances which lead to a considerable wastage of energy if the air streams are also passed over them when they are not required and switched on. The invention avoids the disadvantages in that all of these resistances can be short-circuited when they are not required. <IMAGE>

Abstract: For the purpose of disposal, discarded plastic packaging straps are fed substantially in a radial direction to a cylindrical path of at least one rotating cutting knife and are cut into short pieces. They are severed obliquely over their broad side faces and fed to the cylindrical path of the cutting knife at a uniform rate. The packaging straps are cut up between a cutting edge of the cutting knife and a knife edge past which the cutting edge is moved at a small distance from it. The cutting edge and the knife edge are inclined with respect to each other. The packaging straps are drawn by motor into the path of the cutting knife. The drawing-in of the packaging straps is interrupted automatically if a foreign body is drawn in. Each packaging strap is inserted between two draw-in rollers, which can be pressed against each other and of which at least one is driven by motor. The drawing-in of the packaging straps is interrupted if a predetermined distance between the draw-in rollers is exceeded.

Abstract: Rotation bodies with win symbols are set rotating after the insertion or registering of a minimum stake. When the bodies stop they indicate a winning or losing symbol combination, whereby the machine can be in a normal play state or a special play state. The machine is first set to the normal play state by the entry or registering of a first minimum play stake and is changed to the special play state when the required symbol combination is displayed and an additional, larger stake is applied. The sum of the winnings achievable in the special state is greater than the sum of the stakes and the sum of the achievable winnings for the normal state is less than the sum of the stakes.
