Patent DE-2418603-A1 (DE)
Title: Self-adhesive means for closing wounds - contg. two elements fixed in movable manner on either side of wounds
Inventor: TORRE ROBERT
IPC: A61B17/08
Filed: 1974-04-18
Abstract: One element has a lower adhesive face which adheres to the skin; its upper face has a gripping coating of the "Valcro" (RTM) type. The second element, on the other side of the wound, also has lower adhesive surface and a lateral transparent surface; this is connected to an extension which has a lower face of the "Valcro" type. an important advantage is the rapidity of closing the wound to avoid hemorrhage. No stitches or clips are needed and the wound can be kept under observation beneath the transparent element. In use, the element are placed one on each side of the wound; the extension is pulled to draw the lips of the wound together. The extended portion of the first element is then pushed down on the second element and the two "Valcro" layers stick together. At the same time the transparent material then comes directly above the wound and the quality of the closure can be observed.

Title: Fully-automatic room cleaning system with cleaning robot - includes suitably shaped transition members blocking off inaccessible furniture and walls
Inventor: SCHOPPE FRITZ DR ING
IPC: A47L11/00
Filed: 1974-04-22
Abstract: The automatic room cleaning system is based on a robot cleaning machine with the necessary tools and scanners and on suitably-shaped transition sections attached around the lower edges of the walls of the room and are adapted to the shape of the cleaning tools. Floor-standing articles such as tables, chairs etc. which are to be positioned in the room are designed at the bottom with solid bases or legs which also have a similar shaped transition member. These furniture items are spaces sufficiently from each other to allow passage of the cleaning machine, and may even be fixed to the floor to prevent movement. In this way all visible floor area scanned by the robot machine is accessible to the machine whilst any inaccessible floor space is rendered invisible and basically protected against dirt and dust.

Title: Impregnating and dyeing textiles - with a foamed treatment bath foamed with a combustible fuel gas and burning off gases
Inventor: SCHUFFENHAUER ERHARD
IPC: D06C7/00
Filed: 1974-07-18
Abstract: The impregnation and drying of natural and/or synthetic textile matls. is effected by applying to the textile a bath which has been foamed, in the presence of surfactants, with the aid of a gaseous, combustible fuel, and then burning off the fuel gases. Matls. such as cotton, wool, polyamides, polyesters, polyacrylonitriles, polyolefins and polyurethanes may be e.g. dyed or given other textile treatments, e.g. with anti-statics, dirt-repellants, optical brighteners.

Title: Synthetic fibre strand delivery system - uses a feed channel to deflect travel line from the vertical to reduce forces on striking base of sliver can
Inventor: FLEISSNER HANS DIPL ING
IPC: D01D7/00
Filed: 1974-11-05

Title: Vehicle brake anti-skid arrangement - has normally open control valve between pressure producer and associated dual circuit brakes (SW170576)
Inventor: LEIBER HEINZ ING GRAD
IPC: B60T8/1761
Filed: 1974-12-18
Abstract: The anti-skid arrangement consists of a pressure producer acting via a brake pressure controller producing a variation of the brake pressure, when blocking tendency occurs. The brake pressure producer acts in the first line onto a selected first brake circuit, but subsequently action in the second brake circuit follows due to the series-connection of the control unit and a throttle, to which a pressure reducing valve is connected in parallel. A normally open control valve is fitted between the brake pressure producer and associated wheel brakes. The brake pressure control unit enables maintainance of constant pressure in one brake circuit even when the brake pressure drops in the other brake circuit.

Title: Pneumatic servo for vehicle steering - with closed membrane servo cylinder and backup reservoir operable upon starting
Inventor: SEIFERT GERD W DR ING
IPC: B62D5/10
Filed: 1975-02-04
Abstract: The steering is backed by a pneumatic servo operated by a membrane and a control valve. The system uses either compressed air or inlet manifold vacuum. The servo force is obtained directly from the engine or from a back-up pump which allows the servo force to be generated when the ignition is switched on. A reservoir is used to extend the range of the servo and provide steering when the engine cuts out. The servo is simple to fit and requires no complex hydraulic pumps and circuits. The reservoir cuts in when the pressure supply drops below one atmosphere.

Title: Flow limiting regulator using deformable elements - with limiter located directly in supply line has flow passage through volume filled with elastic balls
Inventor: GOEHRING KARL DIPL ING
IPC: E03C1/086
Filed: 1975-05-26
Abstract: A flow limiting device suitable for maintaining a fixed volumetic delivery rate independent of supply pressure utilises deformable elements.

Title: Automatic pitch control for model helicopter - with spring loaded pin and slot coupling for blade head
Inventor: PELZL ERNST
IPC: B64C27/72
Filed: 1975-09-04
Abstract: The rotor blade is mounted inside a support sleeve (2) coupled to the rotor head, with the blade root sliding in the sleeve with limited axial freedom. A radial peg (4) on the blade root is located in an angled groove (3) in the sleeve. A spring (6) holds the blade in the retracted position. As the rotor blade speed increases the centrifugal force throws the blade further out and in so doing the slot and peg alter the pitch. This provides an automatic pitch control, especially for model helicopters, in which a simple speed control then alters both the engine speed and blade pitch.

Title: Semicircular resistance path of potentiometer - has liquid resistance material deposited by tubes and run together by surface tension
Inventor: STOKHOLM JENS-JOERGEN
IPC: H01C17/30
Filed: 1975-10-17
Abstract: The potentiometer has a semicircular resistance path consisting of a liquid resistance material of given specific resistance applied to the surface of a non-conducting support plate by means of a number of tubes. The tubes deposit given amounts of the liquid onto the support plate and are spaced apart such that the surface tension of the liquid causes it to run together to form a semicircular path. The so-deposited resistance liquid is then heated in the usual manner. The conducting contacts for the resistance path are deposited in liquid form on the ends of the path in a similar manner using tubes.

Title: Coating of porous surfaces with plastics by sintering - by preliminary dipping in resin to fill pores and prevent blistering
Inventor: HELWIG ERNST
IPC: B05D1/38
Filed: 1975-12-23
Abstract: Coating of porous surfaces with plastics by sintering is carried out by removing grease from the workpiece, pref. in a rinsing stage, dipping it in resin and curing this, followed by further coating with plastics by sintering and repeated curing. During the dipping process, all the pores and cavities in the porous surface become filled with resin, thus providing a smooth surface, so that no blistering can occur during the subsequent sintering process. The method can be performed more easily and at lower cost than several sintering processes one after the other, and provides a completely electrically insulating coating with the required dielectric strength.
