Patent DE-2712406-A1 (DE)
Title: Saw blade strip for metal cutting - has tapered cross-section produced by pockets forming small tooth groups
Inventor: KORN HARALD
IPC: B23D61/12
Filed: 1977-03-22
Abstract: The longitudinal saw blade has a tapered cross-section for cutting metals. This tapered cross-section is produced by pockets (1,2) stamped out of the plane of the cutting zone, on either side. The pockets (1,2) form toothe groups (4) of from two to six teeth according to the tooth pitch. The basic profile of the longitudinal saw blade is maintained in the fixing region and at the back. In this way, there can be a multiple sharpending of the saw blade without additional material and operations. In addition, the saw has a greater stiffness and the entry of cooling fluid to the teeth is facilitated. The blade has holes for fastening it at both ends.

Title: Prefabricated concrete component erection and transport anchor - has projecting arm engaging recess in disc coupling head near slit
Inventor: FRICKER SIEGFRIED
IPC: E04G21/14
Filed: 1977-05-05
Abstract: The erection and transport anchor is for embedding in prefabricated concrete components. It is used where the surface on the coupling side, perpendicular to its longitudinal axis, does not have the anchor joint end protruding beyond it. There are spreader arms, or similar anchoring units, protruding from the anchor plane, together with a visually regulated coupling aperture for a locking bolt on the coupling head, bounded by an anchor bridge forming the joint end, projecting into a cut-out in the concrete. The cantilevered arm on the anchor bridge engages a recess in the disc-shaped coupling head sited between the slit for the joint end of the anchor and the head central opening. When the anchor is stressed in serving for erection, a fitting surface lies against a surface on a sidewall of the recess inside the coupling head cross-sectional surface.

Title: Fuel element handling container is decontaminated inside shell - acting as contaminant retaining vessel and strong structural support
Inventor: SCHAAF WERNER DIPL ING
IPC: G21F9/28
Filed: 1977-07-20
Abstract: An appts. for cooling and/or decontaminating fuel element transportation containers in nuclear plants comprises a surrounding sheath or shell to contain the washing water or the like and a support for the weight of the fuel element container. The shell is of rigid construction and itself provides the support for the container. Used in any nuclear plant where external decontamination of a transportation container is required.

Title: Leaf tobacco cutting machine - has two belt conveyors converging towards mouthpiece, with upper belt fed by horizontal cutting screw
Inventor: SIEGERT ROLF
IPC: A24B7/14
Filed: 1977-09-23
Abstract: The cutting machine for leaf tobacco has a hopper (1) into which leaf tobacco is deposited from a vibratory conveyor (3). The leaf material is pushed forwards by a swinging plate (6) forming the back of the hopper. The material is then carried forwards towards a mouthpiece (23) between two belt conveyors (8, 9) one above the other, and conveying towards the mouthpiece end. The upper belt conveyor (8) is preceeded by a cutting screw (31) at right angles to the direction of tobacco travel (7). One end of the screw passes through the side of the hopper, so that excess cut tobacco is discharged onto a return belt conveyor alongside, for recycling. The screw can be raised and lowered under the control of a device mounted adjacent the mouthpiece.

Title: Device for discouraging smoking habit - with silver electrode and battery producing silver traces in mouth-wash water
Inventor: EIBL VOLKER DIPL ING
IPC: A61F5/00
Filed: 1977-10-22
Abstract: A device to wean a smoker from the smoking habit consists of a small container for water in which two electrodes are immersed. One of them is silver coated and is connected to the plus pole of small battery. If a smoker gargles with water from this device once a day, the traces of silver in the water react with the remnants of tobacco smoke in the mouth to give an unpleasant taste. If the smoker persists with this treatment, he loses the desire the desire for tobacco and acquires a distaste for it.

Title: Dual circuit brake pressure regulator - has respective coupled pistons with valves one having deceleration responsive by=pass
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T8/18
Filed: 1978-04-04
Abstract: A control unit has two valves controlling respective rear brake circuits. The valves are coupled by a movable partition for pressure equalisation.

Title: Dynamic and static stability protection for sync. machine - uses evaluation and comparison of significant machine parameters, triggering corrective steps
Inventor: HOEHNE FRIEDRICH DIPL ING
IPC: H02H7/06
Filed: 1978-05-25
Abstract: The circuit is used to supervise the operating point of a synchronous machine with respect to its steady state and dynamic stability limits. It disconnects the machine when the appropriate limit is reached thereby preventing pole slipping. The machine current, voltage and power factor are measured and processed electronically to obtain actual steady state or dynamic operating points. These quantities are compared with their limiting values, and an equality signal used to trip the machine from the network. Instantaneous evaluation of dynamic operating point is used for checking the dynamic stability margin.
