Title: Compensator for linearity errors in random coder - performs coding in two steps and forms corrected random variable by averaging
Inventor: MASSEN ROBERT DR ING
IPC: H03M1/12
Filed: 1978-05-10
Abstract: The compensator has the signal coded directly in a first step and then displaced by half an increment using an adder or subtractor on the input side of the quantiser. Only then is the signal coded. These two steps are accomplished with the aid of a change-over switch and random noise source. A corrected random variable is generated from the random variables formed after the first and second steps by using an adder an subtractor on the output side of the quantiser. The corrected variable's probability is a linear function of the input signal. The corrected variable is obtained by averaging.

Patent DE-2837906-A1 (DE)
Inventor: JAEGER WALTER ING GRAD
IPC: C07C9/04
Filed: 1978-08-31
Abstract: The gasification plant of coal into methane comprises a hydrogenation gasifier (3), a vapour gasifier (4) of a conversion (9) and fractionation (12) device. The coal is first introduced into the hydrogenation gasifier and then into the vapour gasifier in which the complete gasification takes place. The gas produced is then supplied continuously to the hydrogenation gasifier: to obtain a better gasification, the high partial pressure in the gas current will be adjusted so that the hydrogen provided from the operation may be returned to the hydrogenation gasifier. A number of different possibilities are proposed for a combination of such a plant with a nuclear reactor (13) which, with a view to saving coal, will provide the heat necessary for carrying out the process for example by supplying the vapour necessary for the gasification of the vapour.

Title: Electrical machine central stator structure - has double insulation, overcoming problems of mechanical support and connection of stator
Inventor: GUTRIS GIORGIO
IPC: H02K1/18
Filed: 1978-11-24
Abstract: A structure is for electrical machines having a central stator; it is esp. for miniature types. The structure overcomes problems associated with support of the stator, its connection to the remainder of the machine, insulation of the core and the associated windings.

The insulation extends over the stator winding, the stator core itself having a separate insulation layer. The overall insulation is reinforced at its edges and has its maximum thickness at the core faces and constitutes double insulation.
Patent DE-2851761-A1 (DE)
Inventor: PIRINGER OTTO DIPL CHEM DR
IPC: G01N27/06
Filed: 1978-11-30
Abstract: The detector is used in the quantitative trace analysis of volatile substances. It comprises the three main sections, absorber, phase separator and measuring cell. The carrier gas, which contains ion-forming substances, and a liquid, for example water, are mixed in the absorption tube (1), and the ion-forming substances dissolve in the liquid. The phase separator is formed by the jacket tube (4), which is provided with a pipe connecting piece (7) for separating the carrier gas, and the drainage rod (8). At the end (6) of the absorption tube (1), the liquid containing the species to be analysed flows over the drainage rod (8) and strikes the inlet opening (12) of the feed capillary (10) for the measuring cell (13). The inlet opening (12) is completely flooded by the liquid and some of it collects in the collecting tube (17) and drains through the overflow (19). This structural design prevents, on the one hand, gas bubbles from penetrating the measuring cell (13). On the other hand, a liquid seal forms between jacket tube (4) and collecting tube (17) and separates the phase separation space from the external atmosphere. <IMAGE>

Title: Nylon or acetal! resin cable or pipe clip - has borehole with increased elasticity for gripping bolt threads, used esp. for attaching cables to undersurface of automobile
Inventor: MAUER DIETER
IPC: F16L3/08
Filed: 1979-03-02
Abstract: An injection moulding of a nylon or an acetal resin forms a fastening which grips a bolt so that cables, tubes, or hoses can be clipped securely and neatly where required. From the face intended to rest against the surface from which the bolt projects, the moulding has a through hole. This is adequately wide to receive the bolt readily, and diminishes in dia., so that the inner wall of the hole can grip the bolt extending through it. At least one slit reaches along the wall of the section of the hole with the narrower cross-section, down to a transverse hole, to give the necessary elasticity. The fastening is intended esp. for attaching cables etc. to the undersurface of the coachwork of an automobile, to which the stud bolts are welded before rust-proofing, etc.

Abstract: An oscillator arrangement is disclosed which is controllable in its frequency and which comprises a control input for frequency variation and a transformer output, whose frequency-determining oscillating circuit possesses, as a controllable reactive element, two varactor diodes which are connected in opposing fashion and whose capacitance largely represents the oscillating circuit capacitance. Two feedback oscillator circuits are combined to form a push-pull circuit in that the output terminals of the oscillator circuits are connected in respect of d.c. to a reference potential by way of a central tap of the primary winding of a common output transformer. In addition, the two varactor diodes are oppositely poled and interconnected in respect of d.c. by way of the opposite terminals of an oscillating circuit inductance and, at their opposite terminals, are each connected to respective bases of transistors of two oscillator circuits, the emitters of the transistors being connected together and by way of respective resistors to a power supply and the collectors being connected together by way of opposite terminals of the primary winding of the output transformer. In order to form the control input, the oscillating circuit inductance is provided with a central tap.

Title: Variable centrifugal deep well pump - has fluid drive coupling or blade angle controlled as function of level of liquid to be pumped
Inventor: HANAGARTH WOLFGANG
IPC: F04D15/00
Filed: 1979-06-07
Abstract: The vertical centrifugal pump is intended for use as a deep-well pump (2). It is driven via a variable fluid drive (1) or fluid-controlled plate coupling and may have hydraulically variable (19) impeller blade (18) angle. The fluid supply (5) to the drive (1), and possibly that (3',5') to the hydraulic blade angle variator (19), are controlled as a function of the level (7) of the liquid to be pumped. This may be effected by supplying the fluid (3) to the chamber (6) of the fluid drive (1). The fluid (3') can also be supplied to the variator (19), from a floating reservoir (4 or 4') whose level rises and falls with the level of liq. to be pumped.

Title: Endoscope using optical fibre - uses flexible tube terminating in eyepiece and is bent retaining shape into which it is bent
Inventor: MATSUO KAZUMASA
IPC: A61B1/00
Filed: 1979-06-30
Abstract: Assembly and operation of this endoscope is simplified by the optical fibre terminating directly at the eyepiece and the eyepiece attachment being flexible. This eliminates both, the need for an optical prism and the problem of precise physical alignment. The flexible tube (20) contains the flexible optical fibre (12) which terminates at the eyepiece (25). The flexible tube is attached to the eyepiece unit (24) at one end and to the instrument housing (11) at its other end (20a).
