Title: Frequency multiplier with accurate thyristor commutation signals - uses frequency dividers coupled to clock generator and having counter controlled by input signal
Inventor: SAUPE REINHARD
IPC: H02P25/024
Filed: 1980-02-07
Abstract: The frequency multiplier for a thyristor rectifier of a synchronous machine uses digital signals offset by 120 degs. and each 180 degs. in length, obtained from the 3-phase voltage terminals (U,V,W) of the machine by an initial pulse stage (1). A subsequent pulse stage (2) responds to one edge of each digital signal to supply a control signal for a counter (3) receiving a clock signal (f) via a variable frequency divider (4). The counter output controls a second frequency divider (5) receiving the same clock signal (f) as the first its output (5) fed to the thyristor rectifier and being a multiple of the input frequency defined by the division factor (C) of the first frequency divider (4). The multiplier allows the thyristor rectifier to be accurately regulated in accordance with the pole position of the machine.

Title: Yarn-guide arrangement for two-for-one doubling spindle - allows unrolling of singles yarns from rotatable packages
Inventor: THOMA GEORG
IPC: D01H1/10
Filed: 1980-02-21
Abstract: A two-for-one doubling spindle carries a pair of short-traverse cones or cheeses of singles yarn mounted one above the other, on ball or roller bearings, whereby the yarns can be pulled off sideways whilst the cones rotate easily on their bearings. A stationary cylindrical pot surrounding the spindle assembly carries on its inner surface at least one guide eye per unwinding yarn, by which the yarn is led upwards to the entry to the hollow spindle without making contact with the cones or with the outer yarn balloon. The guide eyes are attached to a removable bar which slides into a grooved holder fixed to the inside of the pot, allowing the bar to be quickly removed for easy threading of the yarn guides. This arrangement gives a more uniform tension in the singles yarns and prevents the formation of loops or snarls, partic. in high-twist singles.

Title: Atmospheric emission supervision - by laser beam with intermediate reflectors preceding terminal reflector
Inventor: KRAUSE WILFRED DR
IPC: G01N21/39
Filed: 1980-02-27
Abstract: An area is supervised for atmospheric pollution, esp. for the emission of noxious substances in the environment, by a laser which radiates a coherent light across the area and by several terminal reflectors at the boundary of the area. The reflected signals are evaluated to determine the approximate source of any emission. Intermediate reflectors which are mounted across the laser path to each terminal at certain distances consist either of semi-transparent mirrors or of retroreflectors with a cross-section smaller than that of the laser beam. This results in a better resolution in depth and in a more precise location of any trouble.

Title: Precision turning long workpiece, using several tools - involves adjustment of all tools with their tips in plane orthogonal to work axis, and uses final dia. tool set at radial space
Inventor: PEGOV VADIM BORISOVIC
IPC: B23B1/00
Filed: 1980-08-05
Abstract: The arrangement is intended for accurate turning work (1), particularly with large length to dia. ratio. It is intended for machining where deflection could cause inaccuracy. The machining uses cutting tools (2,3,4) circumferentially equi-spaced on a circle concentric with the work axis. One tool (2) produces the final contour, whilst the others (3,4) have their tips set back (t3, t4) by a certain amount (delta t). All tools are radially adjustable and axially fed (S2, S3, S4). The tool tips lie in a common plane at right angles to the work axis. The setting back amount equals the height of the micro-roughness produced by the final tool. To further compensate transverse forces, the longitudinal feed of the other tools may be continuously adjusted under sensor control.

Title: Monitoring average course deviation of yachts and aircraft - using sensors on compass housing periodically lit by flashlight
Inventor: JAKOB FRANZ DIPL ING
IPC: G01C17/26
Filed: 1980-09-09
Abstract: An arrangement for yachts under sail and power and for aircraft determines the average course deviation w.r.t. a preset desired compass course. The average deviation is displayed for the centre distance covered so that errors can be corrected at larger time intervals than with conventional devices. Alternatively, the total error is accounted for directly or by mapwork. The compass housing, which has six light sensors, can be adjusted about its vertical axis so as to set the desired course. At intervals determined by distance or time those sensors not shielded by the compass disc are lit by a central flashlight. The sensors are connected to shift register inputs via pulse shapers. The register stores the instantaneous deviation values.

Patent DE-3127888-A1 (DE)
Title: Electrical switching apparatus
Inventor: WAHLER HANS DIPL ING
IPC: H01H37/60
Filed: 1981-07-15
Abstract: An electrical switching apparatus is proposed having a temperature-dependent linear actuating motor and an electrical snap-action switch, the two of which are combined in an integral housing, the carrier board closing the upper end of the housing. The bearing element via which the contact tongue is supported by means of a blade bearing and is borne such that it can pivot, and the operating lever (which is acted on by the piston of the actuating motor against the influence of a dedicated restoring spring) are combined to form an integral pivoting lever. Said pivoting lever is, supported, and is borne such that it can pivot on the carrier board, by means of a base section. The carrier board contains a compression spring, in the form of a cylindrical helical spring, as the dedicated restoring spring. Said compression spring is seated in a blind hole in the carrier board and its other end presses against the base section of the pivoting lever, to be precise at a distance from that pivoting bearing point of the pivoting lever which is on the base side. The angled limb (which leads via a curved element to the piston of the actuating motor) of the pivoting lever carries on its front surface the contact tongue which is borne by means of a blade bearing. The restoring spring of the contact tongue leads from said contact tongue freely through the pivoting lever to a supporting element which is attached to the carrier board and at the same time used for the bearing of the pivoting lever on the base side.
