Title: Rope-down gear for climbers - controls lowering velocity while abseiling by brake operated by thread on end of crank handle shaft
Inventor: HERMANI RUDOLF F
IPC: A62B1/10
Filed: 1977-03-18
Abstract: The rope down gear for climbers, is fitted with a control mechanism, which, during its operation does not use friction on the cable. The gear consists of a stirrup-shaped frame (1) of a yielding flat iron section, with the two open ends connected by carrying handle (1a) and the opposite end fitted with grommet (7) by which the cable (8) is guided during the lowering operation. Inside the frame (1) cable drum (3) is fitted rotating on shaft (2). One end of the shaft projecting beyond the frame has a crank handle (5), the other protruding end has reduced diameter (2a) with thread working together with nut (1c) welded to the outside surface of frame (1). By turning the crank handle during the lowering in the appropriate sense the two legs of the frame (1) are pulled against each other and end pads (4, 4') come into frictional contact with discs welded on the inside surface of the frame.

Title: Composite, metal fibre filter sheet with extended life - which utilises two superimposed bonded layers of different dia. fibres
Inventor: KAPLAN STEPHEN JULES
IPC: B01D29/33
Filed: 1977-03-25
Abstract: A composite sheet of filter material comprising two, superimposed layers of randomly orientated metal fibres. The fibre used to make up the first layer i.e. the layer facing upstream during filtration is of greater cross-sectional area than the fibre used in the second layer. The fibres at the interface of the two layers are permanently bonded, e.g. by sintering and compression. A third layer of metal fibres may be sandwiched between two outer layers. The fibres of the third layer have a cross-sectional area intermediate of those of the fibres in the two outer layers.

Title: Zigzag sewing machine stitch selector mechanism - with solenoid-operated automatic disengagement of needle and fabric-feed drives
Inventor: MATSUMOTO SETSUO
IPC: D05B3/02
Filed: 1978-05-24
Abstract: Stitch selector mechanism for a zigzag sewing machine having multiple pattern-cams, one of which has a follower which is moved by the rotation of a stitch-selector dial, wherein a solenoid mechanism activated by depression of the stitch-selector dial automatically disengages the needle bar drive, the zigzag cam follower, the fabric feed follower and the needle position control mechanism before the selector dial is rotated to a new setting. The mechanisms are locked in the disengaged position until the sewing operation is restarted, when they are automatically re-engaged and the solenoid returned to its original position by a return spring. Stitch pattern can be changed simply and rapidly by the operation of a single control dia, permitting the operator to work faster and more productively. The device does not limit the versatility of the patterning mechanism.

Title: Spurious signal suppression for blood pressure measuring - using systolic signal rise period for measuring signal derivation but blocking signal derivation in intervening period
Inventor: NEUSEL ROLF
IPC: A61B5/021
Filed: 1978-11-11
Abstract: The measuring signal is derived only during the time period of the first steep rise of the blood pressure wave generated by the heart. During the interval up to the next blood pressure wave the signal derivation is blocked. Pref. the signal derivation and signal blocking periods are controlled according to the patient's blood pressure wave. Alternately, the blocking period is preset by a circuit. In order to test the obtained measuring signals for their genuineness the time period of the derived signals is determined electronically and compared with an empirical time range for genuine signals. In this manner the signals with deviating period are filtered out.
