Patent GB-1074706-A (GB)
Title: Method and apparatus for the removal of the reserve coil from yarn package tubes
IPC: D03D45/58
Filed: 1964-07-13
Abstract: A reserve coil is removed from a package tube by a p stripping-device by first relatively moving the device and the package laterally of the package axis to locate the device between the coil and the main winding, and then relatively moving the device and the package axially of the package to cause the device to abut the coil and to strip it from the tube.  The device may comprise jaws urged together by a spring to an extent limited by an ajustable set-screw (Fig. 2, not shown).  A package is moved laterally (Fig. 1, not shown) so that the package tube is forced between the jaws of the gripper.  The gripper is now raised by a hydraulic piston so that the end of the tube is forced against a suction nozzle (8); as the movement of the gripper continues, the coil is stripped off and drawn into the nozzle.  In Fig. 3 not shown, a table (9) rotates to bring packages successively beneath a suction nozzle (8), to force the package-tube between the jaws of a gripper and for the package to operate a switch.  This rocks a two-armed lever, to raise the gripper, which is fixed to one arm to strip the coil and to withdraw a slide-valve (14) fixed to the other arm end controlling the suction in the nozzle.  The thread of the coil is clamped when the valve (14) is restored to its original position when the package, having been released by the gripper, falls through a gap in the table 9.  Instead of using the valve as a clamp, the entrained thread may be held within the nozzle by a slot into which the thread is drawn under the movement of a suction pipe connected to the nozzle, or by the movement of the package, or by diverting the air entering the nozzle.

In a method of producing diode units, each comprising a plurality of individual semiconductor diodes connected in series, a plurality of semi-conductor wafers each having a PN junction extending over its whole cross-section, have their surfaces parallel to the junctions tinplated and are laid with these tinned surfaces one on top of the other, after which they are soldered together under slight pressure to form a soldered stack of wafers which is then divided into separate diode units by a cutting process such as by sawing or ultrasonic cutting. The tin-plated layer is about 12 Ám thick, and the soldering temperature is low, as in the range 250‹ to 300‹ C., so that no alloying of the contact material with the semi-conductor body takes place. The tinning process may be carried out in a galvanic bath. Nickel contacts are applied. In the case where the diode units comprise only two individual diodes, these diodes are unilaterally tinned, on those surfaces to be joined, by clipping or cementing them on to a plate of insulating material such as glass during the electroplating process.

Abstract: 1,170,302. Aerials. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. 27 June. 1967 [1 July, 1966], No. 29653/67. Heading H4A. In an aerial array made up of a plurality of elements distributed around a circle, energy is fed at any instant only to a number, less than that plurality, of consecutive elements, and there is a progressive translation with time around the loop of the feed to the elements. Statically operating electronic switches are used for stepping from element to element and continuously varying electronic phase-shifters provide interpolation between steps. As described with particular reference to the de-spinning of the main lobe of radiation from the aerial system of a spin-stabilized earth satellite, twelve elements 1-12, Fig. 1, are arranged in a circle, and three are energized at a time. If the satellite is, for example, rotating in a clockwise sense, at each twelfth part of a revolution thereof power feed is transferred from an element on the left to an element on the right by means of a switching system comprising nine switches C1-C9, Fig. 3, which may be ferrite type circulators. For example, the element 12 is switched out and the element 3 is switched in by the operation of the switch C9. After a twelfth of a revolution the switch C1 changes over from the element 1 to the element 4, and so on. Power is supplied from three continuously phase-shifting devices D1, D2, D3, which maintain the correct direction of the main lobe of radiation between switching steps. The switching sequence is determined by a programming device controlled by pulses from sun sensors and having means for correction by ground command or from an in-board timer. Each element 1-12 may consist of three flat spirals in a row, thus providing circularly polarized radiation and enhanced directivity in a plane containing the axis of the satellite (Fig. 2, not shown). Transmitting and receiving aerials (Ae), (Ar), Fig. 6 (not shown), of the kind described, and a control aerial (T) may be provided. The invention may also be applied, for example to radio beacons.

Abstract: 1277096 Work-holders; chucks HYDRA LOCK CORP 12 June 1969 [13 June 1968]. 29724/69 Heading B3B. A work-holder or chuck comprises a body 22 and a sleeve 28 which is deformable under a pressure medium to internally or externally grip a workpiece, e.g. a cylinder liner 20. A pressure chamber 24 between the body 22 and the sleeve 28 is formed by screw threading 26. The axial length of the work-holder or chuck may be divided into a plurality of chambers to grip parts of the workpiece of different thickness, differential pressures being applied to the different chambers (Fig. 3, not shown). A flange on the workpiece may close off a port in the chuck and indicate that a workpiece is fully inserted. The sleeve 28 may have different radial thicknesses complementary to the varying thickness of a workpiece and this provides differential gripping since the thicker part of the sleeve provides a greater resistance to contraction at the thinnest part of a workpiece which is most easily distorted. The sleeve may be made of a flexible plastics material such as nylon or Teflon (Trade Mark) and may be reinforced by impregnated fibreglass. The fibreglass may be a single helically wound filament or a fibreglass fabric. Rubber or synthetic rubber may also be used with steel wire wound reinforcement. The sleeve is specified as being pliable to enable low pressure to be applied to grip a workpiece to avoid distorting thin workpieces and to allow gripping and centralizing of slightly non-circular sleeves.
