Title: Radio transmitter carried by person buried alive - operates on frequency in MHZ range at which body has half-wave resonance
Inventor: PAUL WERNER ING GRAD
IPC: G01S1/68
Filed: 1979-09-24
Abstract: A person in danger of being buried alive carries a small radio transmitter by which he can be located using a search receiver. The frequency is chosen, in the range 50 to 100 MHz, at which the human body exhibits a half-wave resonance, depending on the dielectric constant of the surrounding medium. The transmitter (S) is worn near the waist and connected to a centre-fed half-wave wire dipole. The dipole arms (s) are coiled up to reduce their physical length (1) without seriously changing electrical length, and arranged to be vertical when the body is upright. Since the body has a broad, damped resonance at the transmitter frequency and the dipole is closely coupled to it, radiation is largely independent of body position, even when lying on top of the dipole.

Patent DE-3026278-A1 (DE)
Title: Synthetic yarn winding - prevents twist on yarn as it traverses the winding sleeve
Inventor: OZAWA YUTAKA
IPC: B65H54/28
Filed: 1980-07-11
Abstract: The traversing action on the yarn, in winding it cylindrically round a sleeve, does not impose any twist on the yarn. In the reciprocating traversing motion, the forward speed differs from the reverse speed. Intended primarily for yarns made of polyamide fibres, the time relationship required for traversing the yarn along the length of the winding sleeve is 10 per cent or more than the equation (I) where TR is the traversing time ratio; delta t the forward traversing time and delta t' the reverse traversing time, when using a high speed spinning and twisting unit. The yarn guide movement is imposed by a roller with a continuous spiral guide groove for a cast or forged section riding in the groove. The method prevents the synthetic yarns from twisting into a band, and also ensures that they are not subjected to breaking forces while being wound.

Patent DE-3106532-A1 (DE)
Title: Valve arrangement for controlling a hydraulic servomotor
Inventor: TRETSCH ADOLF
IPC: F15B13/04
Filed: 1981-02-21
Abstract: A hydraulic servomotor (206) is controlled by a main control spool (16). A control pressure is admitted to the end face of the main control spool (16) by a pilot-control valve (12) in accordance with electric regulating signals and deflects the main control spool (16) against springs (202, 204). The control pressure shifts a relief valve (14), designed as a slide valve, into a closed position. When the control pressure falls away, the relief valve (14) opens and connects working connections (70, 72) to an outlet. Releasable non-return valves (212, 214) lie between the working connections (70, 72) and the servomotor (206). Each non-return valve (212, 214) lying in series with a working connection (70, 72) can be released by the pressure in the other respective working connection (72 or 70). Reliable hydraulic locking of the servomotor (206) is thus effected without leakage when the regulating signals cease. <IMAGE>
