Title: Sloping bed having an electrical raising and lowering device for automatic, infinite inclination
Inventor: HOBERG ULRICH
IPC: A61H1/02
Filed: 1983-01-05
Abstract: The dark sides of civilisation for mankind are obvious, especially for the human body. One-sided activities inhibit blood flow. Faulty stress on the spine and joints often become noticeable through pain. Sloping beds and extension devices are used to provide complete relief of the spine, vertebral discs and joints from their load-bearing function. The commercially available devices of a wide variety of types are sometimes bulky and cannot be handled without the help of another person. The sloping bed described in the following text is intended to eliminate these disadvantages and to permit the device to be used more in the private sector, that is, in gymnasia, saunas and swimming pools.

Patent DE-3310649-A1 (DE)
Title: Single-channel direction finder
Inventor: BODEMANN GERHARD DIPL ING
IPC: G01S3/60
Filed: 1983-03-24
Abstract: For a single-channel direction finder which should be uninfluenced by the information modulation of the signal, the direction of which is to be found, a direction-finding voltage corresponding to the reception of a directional pattern rotating at low frequency is combined with an azimuth-independent all round voltage in separate optionally connectable signal paths, either in phase or with an opposite phase shift of 90 DEG , to form an amplitude-modulated or frequency-modulated aggregate signal, supplied to the receiving channel and then amplitude- or phase-demodulated. From the phase angle of the AF signal thus obtained relative to a reference signal, the direction-finding angle is derived.

Title: Time sequence control for electronically controlled breathing apparatus
Inventor: STIEGLER FRANK DIPL ING
IPC: A61M16/01
Filed: 1983-09-14
Abstract: The invention relates to a time sequence control for electronically controlled breathing apparatus, using integrated circuits of sensor technology, in which breathing rate and ratio of breathing time are to be set in a calibrated manner and varied independently of one another. It essentially consists of two shift register chains, known per se, which are in each case formed by connecting together two 3-bit counters and two binary 1-of-8 decoders. The clock inputs C of the 3-bit counters of the first shift register chain are connected to a squarewave generator via a frequency divider and are acted upon by a clock signal fT/1. Various clock frequencies fT/2 are generated for the second shift register chain by variable resetting. A flip flop is connected to the output of the second shift register chain in such a manner that it is set by the first output pulse and reset by a later variable output pulse. The last output pulse resets the 3-bit counters of the second shift register chain so that a breathing time ratio can be set independently.

Patent DE-3406683-A1 (DE)
Title: Wearing plate
Inventor: GRABE FRANZ
IPC: B65G11/16
Filed: 1984-02-24
Abstract: Wearing plates for conveying and/or storage devices have hitherto been composed of a plurality of layers. It has been preferred to apply a covering layer to a soft base layer, the former being more wear resistant than the latter. Building-up welding may be used. The base layer and the covering layer may, however, also consist of composite sheets. A plurality of such layers can be arranged in strata, one on top of the other. The invention provides for separation of the covering layer 2 and the base layer 3 by spacers 4, so that reception chambers 7 are formed between the layers 2, 3 and the spacers 4. If the covering layer 2 is worn, the material to be conveyed enters the reception chambers 7 and forms a buffer of material there, which protects the base layer 3 against premature wear. <IMAGE>

Title: Process for coating metallic surfaces
Inventor: DETTERBECK HEINRICH
IPC: B05D7/14
Filed: 1984-08-10
Abstract: In known coating processes a primer coating is stoved onto the metal surface at the full stoving temperature, whereupon a symbol impression is applied onto the primer and a further protective lacquer layer is then applied at the full stoving temperature. Particularly in the case of electrostatic powder coating this results, for example as the result of precipitation of dust or inadequate contacting, in smudgy surfaces. According to the invention this problem is overcome by application and only partial curing of a protective lacquer layer, by applying the symbol impression and by subsequent stoving at full stoving temperature.
Patent DE-3434516-A1 (DE)
Inventor: ROHLOFF BERNHARD
IPC: F16G13/06
Filed: 1984-09-20
Abstract: This type of articulation is intended to prolonge the life time of chain drives, to reduce the maintenance costs and to improve the operation characteristics of gear shifting devices. The bolt bearing articulation operates according to the following principle: at the gearing points, the rollers (2) are held above the face of the corresponding teeth and according to the type of links of the chain, they are eccentrically held with respect to the center of the bolts by means of clamping surfaces (4) of the bolt bearings or by means of clamping elements (5), so that the oscillating links of the chain may freely pivot without friction about the rollers (2) during the forward or backward motion of the toothed wheel. The friction in the articulations are exclusively limited to the bearing surfaces of the bolt bearings (6) - bolts (1). As the rollers (2) bear alternatingly on the clamping elements (5) and on the clamping surfaces (4) of the bolt bearings, the elongation between the chain links due to wear remains the same. The open construction of the bolt bearings (6) enables a total osculation of the bolts (1) in the bearings (6).
