Title: Double sampling linear measuring system - has coarse and fine scale readers rigidly coupled together to permit logic circuitry to compensate for non-alignment
Inventor: HACKERT UWE DR ING
IPC: H03M1/00
Filed: 1977-10-05
Abstract: An absolute periodic linear measuring scale, such as an Inductosyn scale, serving as a fine measuring system is mounted parallel to an abslute linear Gray scale serving as a coarse measuring system. The corase and fine measuring systems have equal divisions T. Within these divisions, the fine measuring system can resolve subperiodic measurements (e.g. 1/100 T). The scale reading device of the fine measuring system and of the corase measuring system are rigidly connected together. Double sampling of the coarse scale permits the logic circuitry to compensate for non-alignment of the coarse and fine scale transistions.

Title: Failsafe interlock for automatic exposure camera - with time delay to close shutter if not closed by exposure circuit to avoid subsequent faulty photographs
Inventor: MAITANI YOSHIHISA
IPC: G03B7/16
Filed: 1977-10-14
Abstract: The automatic camera, with integral flash, operates the flash automatically as a fill-in mode if the illumination is not sufficient. The ready state of the flash contacts starts a failsafe time circuit which provides a shutter closing signal after a time interval corresponding to the longest flash exposure. The timing circuit comprises simple RC loops coupled to the exposure control. It is only operated when the fill-in flash is used. It prevents the shutter being left open with incomplete exposure, so that subsequent shots are not ruined.

Title: Woltmann type flowmeter with simplified regulator - has one-piece impeller unit rotated to vary regulator inlet apertures in inlet support ring and manifold
Inventor: DEWALD FRITZ
IPC: G01F1/12
Filed: 1977-11-10
Abstract: The Woltmann type flowmeter incorporates a simplified regulator. The metering mechanism is of unit construction and itself forms the regulator section. The input bearing bush of the impeller (4) is accommodated in an inlet hub (7) which, together with the guide ribs (8) and the tubular housing for the impeller assembly (9) and retaining ring (10), is formed from a one-piece plastics injection moulding (11). The retaining ring has four regulator openings (12) which are aligned with recesses (13) in the inlet manifold (14). By rotating the entire impeller unit, the amount of overlap between the openings and the fixed channels can be varied and thus the aperture altered. The cannels are connected with an annular chamber (19) surrounding the impeller casing (9). This provides a by-pass path for the fluid medium.

Title: Voltage adjustment circuit at vacuum of X=ray generator - makes effective voltage at vacuum into function of predetermined tolerances
Inventor: WACH PAUL PROF DIPL ING DR TEC
IPC: H05G1/32
Filed: 1977-12-20
Abstract: The circuit is designed to adjust the voltage at vacuum of an X-ray generator which has no input transformer. The circuit has a multi contact switch which is coupled to another multi contact switch. The switch varies the series resistance of a voltmeter which indicates the vacuum voltage of the network. The voltage range indicated can be varied according to the resistance connected in series with the voltmeter by the switch. The choice of series resistance can be made a function of the tapping of the converter transformer so that the prescribed voltage appears at the voltmeter. A comparison circuit, whilst comparing the fall in voltage at the voltmeter with the prescribed voltage, triggers a photographic recording or an X-ray irradiation. The triggering being actuated when there is a sufficient difference between the voltages. The comparator (8) emits a signal to an 'AND' circuit which is connected to a switch in the supply conductor to the high voltage transformer.

Title: Open-end spinning rotor for differing staple lengths - has truncated cones with undulating mantles joining fibre groove
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D01H4/10
Filed: 1977-12-23
Abstract: An open-end spinning rotor consists of a hollow body fitted at the end of a driven shaft which is free to rotate. The upper section of the rotor has a feed opening concentric to its axis of rotation. This widens out diametrically to join the bottom section of the rotor and form a fibre collecting groove. A fibre channel is directed through the feed opening towards the inner wall of the rotor. The surface of the upper section is a series of undulations aligned towards the fibre collecting groove, the crests of the waves of which are inclined so that their projections intersect or cross the rotor axis. In each normal plane of the rotor axis, the wave crests are at the same spacing and at the same height. To overcome the tendency towards uneven laying into the fibre groove, of individual fibres which then twist round the zone already spun to form a slub. The rotor indicated finds application over a wide range of staple lengths and produces uniform threads from them.

Title: Elimination of copying light required for copying of colour originals - by obtaining colour density difference curves for each scanned area of film strip
Inventor: THURM SIEGFRIED DIPL PHYS DR I
IPC: G03B27/73
Filed: 1979-03-28
Abstract: The method is of determining, in each f the primary colours separately, the amt. of copying light required to be used during te copying of colour originals that are combined to form film strips. The film strips are scanned are by area photoelectrically, and separately in each of the primary colours and the results of the measurement are used to control the amts. of copying light. For each scanned area, a first difference between the density values of two primary colours is formed, and a second difference between the density values of one of those primary colours and the third primary colour is formed and the mean density of all three primary colours is formed. On the basis of, in each case, a number of orginals of a film, colour density difference curves over the mean density are generated from the assignment of the colour density difference values to the associated mean densities.
