Title: Method of and device for effecting contact-free measurement by optical scanning
IPC: G01B11/02
Filed: 1976-08-02
Abstract: 1532834 Measuring dimensions photo-electrically KOCKUMS AUTOMATION AB 2 Aug 1976 [15 Oct 1975] 32054/76 Heading G1A Apparatus for measuring the positions of three or four points A-D Fig. 1 on the cross-section of an object 3 (e.g. a rough-sawn plank) comprises: means 5 for causing relative motion P between the object 3 and a sensor system including radiation transmitters 11, 12 (e.g. infrared LEDs) and receivers 21, 22 (e.g. photo-transistors) for sensing rays In, 2n, the system being positioned so that the projections of the rays, on a plane parallel to them both and defining a section plane of the object 3, cross each other and are both inclined to the direction of relative motion P. The angle of inclination α and of the rays is so chosen with regard to the shape of the object that, if the object thickness t is known, and the conveyer 5 displacement is signalled by a transducer 6, the positions of salient points A-D may be computed from the displacements at which these points respectively begin and cease to interrupt the respective rays In, 2n. In a modification Fig. 3 each path is defined by two rays 1A, 1B and 2A, 2B inclined to the direction of travel P at different angles and defined between two transmitters 11A, 11B and 12A, 12B and common receivers 21, 22 as shown, or vice versa. The interval e.g. between the interruptions of rays 1A and 1B by the upper leading corner of the object 3 defines the height of that corner, so making prior knowledge of the height of that corner unnecessary. Fig. 4 illustrates apparatus for measuring contours in several planes I, II, III and is a plan view in a direction perpendicular to the ray In of Fig. 1. Either the transmitters or receivers, or both, may include light guides 113, 23 formed with spherical ends 11', 21' and communicating with respective remote source means 115 and detector means 25. A common source with time-multiflexed detectors, or vice versa, may be used. Light paths are mutually screened by slots 16, 16' in front walls 15, 15' of channels 17, 17' which may be kept dust-free by gas flow T, T. Interference from stray light may be avoided by modulating the sources.

Patent GB-1531608-A (GB)
Title: Stretching process
IPC: B29C48/90
Filed: 1976-08-04
Abstract: The known mode of operation, in which a non-circular hollow profile strand in the thermoplastic state is stretched in the transverse direction with the aid of a pressurised gas enclosed in the hollow space (10) of the hollow profile strand (8), during passage through a calibrating device (13-20) the free cross-section of which increases in the direction of travel of the strand in the extent of the desired stretching, is improved according to the invention in that a lubricant (24) of at least 5000 cP is introduced between the hollow profile strand and the inner wall of the calibrating device under operating conditions. A uniform sliding of the strand in the calibrating device is thereby ensured. In addition, the strand can be simultaneously stretched in the longitudinal direction by taking it off, by means of a take-off device (31/32), from the calibrating device at a higher rate than it enters the calibrating device. After it has achieved a final cross-section, the hollow profile strand is cooled to below the softening temperature. <IMAGE>

Title: Television scanning systems
IPC: H04N5/073
Filed: 1938-11-10
Abstract: 513,983. Television. HAZELTINE CORPORATION. Nov. 10, 1938, No. 32670. Convention date, Dec..2, 1937. [Class 40 (iii)] One set x of synchronizing signals (e.g. line, Figs. 7, 8) has a steep leading edge and a less steep trailing edge, while the other set y (e.g. frame) has a steep trailing edge, and a less steep leading edge, and the signals are separated by a differentiating process. The frame pulses are produced by applying rectangular pulses a, Fig. 1, from 29 to a pentode 31 to render it non- conducting and so allow condenser 32 to charge slowly over resistance 33, the condenser being abruptly discharged at the end of pulse a when valve 31 conducts. At the receiver, the synchronizing signals are isolated by a biassed valve 48, Fig. 2, and applied to inductance 51 which differentiates them to produce pulses whose amplitude depends on the steepness of the edges and whose direction depends on the direction of slope, Figs. 9 and 10. These pulses are applied to oscillators 45, 46, one being tripped only by large amplitude positive pulses and the other by large amplitude negative pulses. Alternatively, a diode may isolate the pulses, and the pulses to one generator be reversed by an inductance so that both generators may be tripped by pulses of the same sign, Fig. 3 (not shown). If the amplitude of the synchronizing pulses is dependent on the direct current components, the separated synchronizing pulses may be applied to bias the control grid of the cathode ray tube. The system described is for a 2:1 interlaced scanning. Specification 407,409 is referred to.
