Title: Method and apparatus for producing a facial mould from living persons in order to produce a bust
Inventor: BUENDER HANS-JOACHIM
IPC: B44C3/00
Filed: 1981-06-26
Abstract: Facial moulds are made with plaster or elastomeric moulding pastes in order to obtain a negative mask which is to be cast. Because of the risk of the vulnerability of the eyes and the need to take into account respiratory activity in the production of the mask, it is difficult to release a solidified full mask, in contact with the face, in the event of the model suffering from claustrophobia. The object to be achieved in eliminating this defect seems, according to the invention, to lie in carrying out the mask production in such a manner that, with the assistance of a mouth protection apparatus (s) bonded to the face, the eye protection apparatuses (i) and an apparatus (a) in accordance with drawings A and B, only one half of the face is first moulded and released, after which the other side of the face is moulded with the loosely positioned mask of the first part, and the full mask obtained is then released, after which the mouth protection apparatus, integrated in the mask, is removed and the mouth, which is still free, is moulded. After this, soft kneading material is pressed through the protection apparatus (i) against the closed eye and the reconstruction of the opened eye is undertaken on the plaster positive. <IMAGE>

Inventor: JUNG KARL-HEINZ
IPC: B23B31/20
Filed: 1981-07-11

Title: Carrying apparatus for skis
Inventor: GAWEL JAN
IPC: A63C11/02
Filed: 1981-07-22
Abstract: The invention relates to a carrying apparatus for skis. The carrying of skis in an oblique position over the shoulder requires a relatively large safety margin or jeopardises third parties in the relatively close vicinity in the event of the uncontrolled upward and downward movement and swinging of the skis. It is therefore proposed, for the safety of the environment and for a safe and freer forward movement of the carrier himself, that a carrying apparatus be used by means of which the skis can be suspended on the shoulder, thus adopting a space-saving and non-hazardous position. The carrying apparatus substantially consists of a carrying strap (1) and two retaining straps (2) at the ends thereof, one retaining strap (2) conventionally being attachable under the ski binding (10) and the other retaining strap (2) being attachable above the latter to skis (11). <IMAGE>

Patent DE-3131036-A1 (DE)
Title: Rubber-metal support
Inventor: PLETSCH HUBERT
IPC: F16F1/387
Filed: 1981-08-05
Abstract: In a rubber-metal support consisting of an outer bearing bush and an inner bearing bush with a rubber body arranged between them and oblique surfaces to allow the radial displacement of the bearing bushes relative to one another under the action of axial forces between the bearing bushes, the service life and response of the support are improved by the fact that the inner bearing bush is mounted in a freely rotatable and axially displaceable manner in the rubber lining of the outer bearing bush. The radial displacement of the inner bearing bush relative to the outer bearing bush under the action of axial displacement forces between the two bearing bushes is effected by means of a rotationally symmetrical taper on the inner bearing bush which is guided in an eccentric recess in the rubber body.
Patent DE-3133672-A1 (DE)
Title: Program feed system
Inventor: BARABAS UDO DR ING
IPC: H04N21/434
Filed: 1981-08-26
Abstract: The invention relates to a program feed system which transmits a television signal at intermediate frequency from a first terminal station for wireless reception via a sampling switch (2), a PPM modulator (3) or PCM encoder, an electrooptical converter (4), an optical waveguide (5), an optoelectrical converter (6), a PPM demodulator (7) or PCM decoder and via an IF bandpass filter to a second terminal station. According to the invention, a phase-locked loop (10) for controlling the sampling switch (2) is provided at the input (1). This switch and the PPM modulator (3) or PCM encoder form a synchronous modulator (11) or encoder which carries out the sampling synchronously with the picture carrier and only evaluates one half wave of the modulated picture carrier. The PPM demodulator (7) or the PCM decoder are constructed in such a manner that they output PAM signals having a small duty ratio. The invention results in a signal/noise ratio which is higher by 6 dB on the noisy transmission link. At the output, exactly the same IF band appears as at the input. <IMAGE>

Title: Method for detecting the horizontal component of the earth magnetic field
Inventor: GIELEN HARALD
IPC: G01C17/30
Filed: 1982-02-17
Abstract: A method is described by means of which the horizontal component of the earth magnetic field (H) is determined by means of an earth field probe (1). Two output signals (U1, U2), which contain the direction of the field vector (H) in a phase shift, are supplied to a first evaluating circuit (14).

Title: Closed front-mounted combustion chamber with compressed-air gas burner for petroleum/natural gas heating and petroleum heating and separating devices
Inventor: SCHMIDTKE GERHARD ING GRAD
IPC: F23D99/00
Filed: 1982-08-19
Abstract: Closed front-mounted combustion chamber with compressed-air gas burner for petroleum/natural gas heating and petroleum heating and separating devices. The front-mounted combustion chamber is mounted on flame pipes on devices for heating petroleum and natural gas or on devices for heating petroleum for separating water and gas. These devices are erected on the production systems for obtaining petroleum and natural gas. The front-mounted combustion chamber with the compressed-air gas burners guarantees a stoichiometric adjustment of the gas/air mixture and thus optimum efficiencies as main burner (1) and pilot burner (2) are provided positively with gas and air outside the front-mounted combustion chamber. With this front-mounted combustion chamber, it is guaranteed that the combustion-related values stipulated by the Federal immission law - latest version - are achieved. As a result of the optimum combustion, it is possible to increase the efficiencies from between 48 and 52% previously to 89 to 90% (energy saving law). <IMAGE>

Title: Method for regenerating the adsorber units in an installation for the dry recovery of solvents from a gas stream, and installation for implementing said method
Inventor: SCHEUCHL RICHARD
IPC: B01D53/04
Filed: 1983-02-02
Abstract: The method according to the invention is particularly suitable for the recovery of substances, which are not readily adsorbed or which are present in low concentrations in the gas stream. According to the invention, for the purpose of regenerating an adsorber unit, a regeneration adsorber unit is used, to which the desorbate driven off from an adsorber unit is first transferred with the aid of an inert gas stream. The inert gas leaving the regeneration adsorber unit is heated once more and is used in the circuit for regenerating one of the operational adsorber units. By using an additional adsorber unit or a regeneration adsorber unit it becomes possible to provide a comparatively very pure inert gas stream for the regeneration of the operational adsorber units, and as a result, the method according to the invention is able to achieve a very high efficiency in the desorption process of the adsorber units in question. <IMAGE>
Patent DE-3303841-A1 (DE)
Title: Pattern testing device
Inventor: MIYAGAWA MICHIAKI
IPC: G06V10/36
Filed: 1983-02-04
Abstract: In a pattern testing device, a pattern (50) to be tested is scanned by a photoelectric transducer (51). The electrical output signals of the transducer are split by a splitting circuit (52) into picture element signals which are processed further as binary coded output signals. Several window areas can be set within the field of vision of the photoelectric transducer (51). The binary output signals are used as a basis for the measurement of particular feature variables of the pattern to be tested in each window area. A primary decision circuit (56) decides that the pattern is good in a window area when the relevant feature variable is within a predetermined threshold range. Otherwise, the pattern in this area is poor. A secondary decision circuit (57) compares the results of the primary decision with a table formed in advance in order to make a go/no-go decision. If necessary, a correlation with subsequent correlation decisions is carried out in a primary correlation decision circuit (61) and a secondary correlation decision circuit (62), using the feature variables of adjacent window areas. <IMAGE>
