Patent DE-3342169-A1 (DE)
Title: Table
Inventor: HERTEL REINHARD
IPC: A47B91/16
Filed: 1983-11-22
Abstract: When tables are placed on uneven ground, for example a garden terrace, there is frequently a desire to align the table top essentially horizontally or, in tables with four legs, to prevent wobbling. There are already numerous constructions for adjusting at least one leg in its longitudinal direction. The invention relates to a table which, by a novel combination of technical features, some of which are known individually, achieves a particularly simple and convenient adaptation to any unevenness. At least one of these table legs has at the lower end a channel (3) which is open at the bottom, is aligned upwards, and in which an inner part (4), which is matched to the dimensions of the channel, is mounted so as to be longitudinally displaceable, and a compression spring (10) which is supported against the inner part, is arranged in the channel in such a way that the inner part (4) is pressed downwards by the spring force. A guide element (6) is present which prevents the inner part (4) from twisting relative to the table leg (2), but allows longitudinal displacement, and a fixing device (6) is provided which can be adjusted selectively by hand and which, in one position, fixes the inner part (4) against longitudinal displacement inside the table leg (2), and, in the other position, releases the longitudinal displacement. <IMAGE>

Patent DE-3404712-A1 (DE)
Title: Instant camera
Inventor: SACHS GUENTER
IPC: G03B7/22
Filed: 1984-02-10
Abstract: Since instant picture material reacts as a function of temperature, it is recommended that an exposure-correcting device that is conventional in instant cameras be set to a "DARKEN" mark at relatively low temperatures and to a "LIGHTEN" mark at relatively high temperatures. It is proposed to assign a temperature-indicating element (4), which consists of a strip-shaped stick-on thermometer and has a plurality of indicator fields (4a) which are tuned to different temperature ranges and indicate different temperatures by change of colour, to the camera-side exposure-correcting device (9). The temperature display element (4) likewise has lighten/darken marks (4b, 5 and 4c, 6) which correspond to the lighten/darken marks (9a, 9b) of the exposure-correcting device (9). The exposure-correcting device (9) can be set in accordance with the coloured marking of the indicator fields (4a) located in the lighten or darken region (4b, 5 or 4c, 6) or located in the central region of the temperature display element (4). <IMAGE>

Title: Sewing machine for simultaneous seam formation on opposite sides of a piece of sewing material
Inventor: DRAGHICCHIO PIETRO
IPC: D05B1/12
Filed: 1984-02-28
Abstract: The sewing machine for simultaneous seam formation at opposite edges of a piece of sewing material has a pair of needle bars which are arranged at a distance from one another and each of which is designed for receiving one or more needles and which are arranged in a common sewing-machine head. Furthermore, the sewing machine has two oppositely arranged base elements which are located at a distance from one another and which each contain grippers and feeders assigned operatively to one of the needle bars, which project downwards from the single sewing-machine head. The grippers and feeders located at a distance from one another are arranged in mutually parallel directions and cooperate with their respective needles in such a way as to form sewing devices which are arranged at a distance from one another and which are connected by the sewing-machine head, a force-transmission system connecting the various stitch-forming devices to a single drive motor. <IMAGE>

Title: Balanced mixer with a hybrid transformer
Inventor: GOMI SHINTARO
IPC: H03H7/01
Filed: 1984-03-15
Abstract: A balanced mixer circuit having a transmission-line hybrid input transformer has several switching elements which are connected to a pair of balanced outputs of the hybrid input transformer and switch in synchronism with the local-oscillator signal, and an impedance circuit which is placed across the balanced outputs of the hybrid transformer. The conversion efficiency and the signal/noise ratio of the balanced mixer circuit considerably improve by selecting the impedance characteristics of the impedance circuit in such a manner that the impedance value is high for the frequency of the RF input signal and of the local-oscillator signal and the impedance value is low for the IF signal frequency.

Patent DE-3424166-A1 (DE)
Title: Process for the production of SiC coatings on high-strength carbon fibres
Inventor: FITZER ERICH PROF DR
IPC: D01F11/10
Filed: 1984-06-30
Abstract: The invention relates to the development of a SiC coating process (Figure 1) in which the initial strengths of the carbon fibres are largely retained, SiC bridges between the monofilaments of the fibre bundle are prevented and high coating rates of the fibre bundles are achieved. It is characterised in that the SiC deposition is carried out in two stages with the aid of a shaking device for the fibres. First of all, in a first stage, the carbon-containing silane required to form a thin but continuous layer, such as for example trichloromethylsilane, is decomposed in an argon atmosphere. In a second stage the layer thickness is enlarge by decomposing the silane in a hydrogen atmosphere. This manner of production achieves a high fibre strength with high deposition rate since the uncoated carbon fibre does not come into contact with hydrogen and is not damaged by the formation of hydrocarbon. Reduction of the penetration depth of the reactands into the fibre bundle due to the increased deposition rate, which leads to non-uniform coating of the fibre bundle and to formation of SiC bridges between the individual filaments, can be avoided by using a shaking device for the C-fibre bundle. <IMAGE>

Title: Method of optically scanning the fundus of the live eye
Inventor: SCHWEITZER DIETRICH DIPL ING D
IPC: A61B3/12
Filed: 1984-11-28
Abstract: The invention relates to a method of optically scanning the fundus of the eye. It has the object of determining the spectral scattering of fundus regions of interest without any adverse effect of eye movements on the measurement results. According to the invention, eye movements are triggered for formation of the measurement signal as physiological scanning. For this purpose, two alternately monochromatically illuminated spots are positioned on the fundus of the eye in such a way that the foveola fixes on the spot illuminated first, whereas the fundus region to be examined lies between the two spots and/or symmetrically relative thereto with regard to the foveola. When illumination of the other spot starts, the eye of the subject becomes fixed on this spot. The scattered light is measured from that fundus region which is illuminated by the spot during the fixation movement. If the light alternation frequency is appropriately chosen, the eye fixes on the alternately illuminated spots almost automatically.

Title: Split tie rod for cutting tools with interchangeable tool head
Inventor: BRABAND GUENTER
IPC: B23B29/04
Filed: 1984-11-29
Abstract: The invention relates to a split tie rod for cutting tools with interchangeable tool head, which tie rod consists of a rear tie-rod part, which is rotatably arranged in the tool holder and can be actuated by a screwing tool, and of a front tie-rod part which is axially displaceable in the rear tie-rod part and in the tool holder and can be brought into operative connection with the tool head. The aim of the invention is to simplify the automatic tool change in cutting tools with interchangeable tool head. The object of the invention is to perfect the design of the tie-rod parts and to arrange them in such a way that no axial movement of the screwing tool is necessary for actuating the tie rod. This object is achieved in that   - the front tie-rod part is axially secured in the tool holder and has an inner polygonal profile, and - the front tie-rod part has a shank end corresponding to the inner polygonal profile of the rear tie-rod part, is provided with an external thread at its front end, and is flexibly supported against the rear tie-rod part.   The invention can be applied to cutting tools with interchangeable tool heads, in particular during the automatic tool change.
