Patent DE-2448788-A1 (DE)
Title: Desiccator for reducing humidity content of standing cereal crops - consists of arms which fan out the crop, and nozzles spraying fluid
Inventor: WIENEKE FRANZ PROF DR ING
IPC: A01M7/00
Filed: 1974-10-12
Abstract: An air current is produced by the machine which enables the fine droplets of herbicide or other spray fluid produced by the nozzles to reach deeper down into the crop. The air current is produced by rotating arms which have fixed guide-pieces or elastically sloping surfaces acting as propellers during turning, and the arms rotating on a vertical axis act as blades of an axial fan. The apron surrounding the rotors guides the air current, and can preferably be fixed to shield-brackets surrounding the rotors. The nozzles are fixed onto the moving arms. The container for the spray liquid is positioned on a tractor or on the frame supporting the arms.

Title: Machine-made linked jewellry strap - comprises alternately coiled members designed for easy attachment of connecting pins
Inventor: TESCH BERNHARD
IPC: A44C5/00
Filed: 1975-01-11
Abstract: The articulated jewellry strap for use as watchstraps, bracelets, necklaces etc. comprises several articulated links (11, 12.. 19) which consists of coiled members wound alternately left and right and connected together by connecting pins (21, 22, 23....) bent in at the ends to prevent axial displacement. Each pair of connecting pins is secured by the end of one of the coiled members so that on placing the articulate links side by side after inserting the connecting pins the bent end of the coil forms a stop for the pin which is inserted from the opposite side after adding the next link. The ends of the right-hand links all lie on one edge of the strap whilst the ends of the left-hand links lie on the opposite edge.

Title: Antenna amplifier with several channel filters - band-pass filters have terminals for connection of amplifiers with different gains
Inventor: BIEBL HANS DIPL ING
IPC: H04N7/10
Filed: 1975-01-27
Abstract: The invention provides an aerial amplification system having flexibility to allow for extensions while requiring only a limited number of stock components. Amplifier with suitable gain can be selected, and channel amplifiers and band pass filters are made as independent units which can be plugged together. Each channel amplifier is connected to a common main line through a filter and a directional coupler. Each channel band pass filter contains a section of an output line, so that a series of filter units plugged together form a through main line. Channel amplifiers are also plugged together, and followed by a common master amplifier.

Title: Pattern of connection wires - is shaped and applied to board mechanically and there are contact holders formed by loops in wires
Inventor: SCHOEN FREIWALT DIPL ING
IPC: H05K3/34
Filed: 1975-02-27
Abstract: The connection wire pattern consists of wires shaped mechanically and applied to an insulating support board. To form connections with the terminal wires or legs of a component, the wires of a component, the wires are looped around holes in the board. The terminal wires or legs can then be soldered directly to the wire loops without the use of additional connection means. The loops in the wires are formed mechanically by wrapping around a post.

Title: Contact-free magnetic centring for high speed rotor - uses stationary and rotating magnetic bearing rings
Inventor: DSCHEN YUAN-HENG DIPL ING
IPC: F16C39/06
Filed: 1975-04-10
Abstract: The shaft bearings for a rotating body (1) consist of magnetic wings which are attached to the rotor shaft (4) and the stationary bearing block (6). The magnetic rings (5) on the rotor shaft are radially tapered so that the larger side is in contact with the shaft. Spacer rings (8) with reverse taper are shrunk onto the shaft so that they retain the magnetic rings at very high speeds. The stationary bearings are similarly constructed but without tapered axial faces. They are of the same polarity so that mutual repulsion between shaft and bearing bush occurs. The axial rotor location is achieved with similar pairs of adjustable magnetic rings (13-16).

Title: Camera with recessed sliding control for film transport - has sprung coupling to ensure accurate film drive from lever
Inventor: BRAEUNING GERHARD
IPC: G03B17/00
Filed: 1975-06-11
Abstract: The camera is fitted with a pull-out slider coupled to the shutter setting lever. A control lever is pivotted between the slider and the camera. When the exposure is completed the slider is pushed back into the camera and operates on the setting lever using a second cam. A film perforation lever engages a sprocket hole when the film has been transported by a frame, with the film drive coupled to the setting lever. The perforation lever operates a linkage to block the action of the setting lever using ratchet faces. If the slider is to be pushed completely into the camera then the extra force required disengages the driving claw. Otherwise, the slider can be pulled out of the camera again for another exposure.

Title: Heat pump with thermal drive - uses IC engine driven compressor in combination with heat converting equipment
Inventor: HERRMANN HANS DR ING
IPC: F25B27/00
Filed: 1975-09-30
Abstract: The heating installation uses an i.c. engine driven compressor heat pump. It is intended for use in conjunction with air conditioning space heating, service hot water - and process heat generating. The design uses a combination of the heat pump with several heat converting appliances. The exhaust gases from the IC engine driving the heat pump are ducted to a heat exchanger.

Steam jet- or absorption-type heat pump uses the heating medium off the steam generator or cooker in heat exchangers.
Patent DE-2544832-A1 (DE)
Title: Precision demoulding and transfer of blow-mouldings - from a mould to an after-treatment station for e.g. automatic flash removal
Inventor: FROHN WALTER DR ING
IPC: B29C49/32
Filed: 1975-10-07
Abstract: Plastic hollow bodies, which are to be removed and after treated, e.g. for removal of flash, are blow-moulded in a machine constructed with >=1 blow-mould closure unit which can be moved between a tubular parison-reception station and a removal station. The blow-mould closure unit is suitable for the reception of a divided blow-mould provided with a calibrating opening, while the machine has at least one after-treatment station for the blow moulded hollow body. In this improvement the hollow body on its path from the mould to >=1 after-treatment station is alternately held by grippers in the form of clamping mandrels engaging the inner wall of the body and clamps gripping the outside of the body so that it maintains a stable position. At least some of the grippers are movable for the transport of the hollow body from the preceding gripper and its transfer to the next successive gripper. At least one gripper positions the hollow body in an after-treatment station. The transfer of the hollow body from one gripper to the other takes place during interrupted transport motion such that the first effective gripper only leaves its clamping position when the next effective gripper has attained its clamping position. Method enables after-treatment e.g. removal of flash, application of labels or printing, etc. to be carried out completely automatically, since the blow-moulded hollow bodies are maintained in a stable, reproducible position.
