Title: A method and apparatus for modifying synthetic heat-settable yarn filaments
IPC: D02G1/02
Filed: 1963-05-06
Abstract: 978,371. Twisting yarns. TURBO MACHINE CO. May 6, 1963 [May 21, 1962; Sept. 12, 1962], No. 17745/63. Heading D1F. A thermoplastic heat settable yarn twisted with a further yarn, set and cooled in the twisted state, and then withdrawn from the other yarn at a rate automatically controlled so that the tensions in the separated yarns are substantially equal. If the tension of one yarn is higher than the other then the separation point 5 Fig. 1, will move towards the corresponding set of conical rolls 15,16 causing the withdrawal rate of the yarn of the higher tension to lessen and the withdrawal rate of the other yarn to increase till balance is obtained. Roll 15, of rubber or rubber faced is pressed by spring 23 against metallic roll 16 which is mounted on support 21 adjustably pivoted at 22 to main frame 10. Roll 16 is driven through flexible drive shaft 36 and gearing 30-35 by lower feed roll shaft 27. As shown in Fig. 1, two thermoplastic yarns Y pass several times around feed rolls 11, about pins 14, and, twisted together, over hot plate 37 or through a heating tube, and optionally, through cooling means 43. In another embodiment, Fig. 8 (not shown), two yarns twisted together with S twist and two yarns twisted together with Z twist are passed side by side through the heating and cooling zones and then at the separation point 5 each S twist yarn is withdrawn with a Z twist yarn to produce two "balanced" yarns. Alternatively the "further yarn" may be a dummy yarn or a filament circulating in a closed loop (Fig. 9 not shown), or otherwise may be of a different material and/or denier to the "first yarn". In a further example (Figs. 11 and 12 not shown) filaments are extruded from a spinneret and formed into two substantially equal bundles which may be temporarily wound on-bobbins. The bundles are then hot drawn, twisted together and separated by the apparatus of Fig. 1, and plied together to form a single yarn end.

Title: Scanning camera
IPC: G03B17/12
Filed: 1971-05-28
Abstract: 1354617 Scanning cameras EASTMAN KODAK CO 28 May 1971 [15 June 1970] 17750/71 Heading G2A In a scanning camera, in which a viewed scene is imaged, increment by increment, through a lens system and a slit aperture on to a moving film strip, the axis about which a movable element of the scanning means pivots passes through the first principal point of the lens system. This arrangement reduces the "smearing" effect due to the apparent movement of the effective viewpoint of the lens. As shown, the scene viewed is reflected from a mirror 22 which can pivot on a shaft 23, through a lens system 24, and reflected again from a fixed mirror 21 to pass through an aperture slit 15 on to the film sheet 12. The sheet is transported in the direction 13 by sprockets 17 driven by a motor 19. A lever 27 on a fixed pivot 28 has a nose 29 at one end which follows a cam 26 fixed to one of the sprockets 17. The other end of lever 27 bears against the end 31 of an arm 32 fixed to the top end of the mirror shaft 23. Shaft 23 is biased anti-clockwise, so that nose 29 is maintained in contact with the cam 26. Thus by shaping cam 26 to an appropriate profile a predetermined relationship may be established between the linear movement of film sheet 12 and the angular movement of mirror 22. The lens 24 is a telephoto lens of the type shown in Fig. 3, having a positive element 45 and a negative element 46. These are combined so that the principal points P 1  and P 2  are located forwardly of the lens elements (as shown) in Fig. 3, so effecting an increase in the focal length F. The inventive step consists of locating the first principal point P 1  at or near the axis of mirror 22. The arrangement also enables the camera to have a more compact structure, and also a smaller mirror 22.

Abstract: 1,247,151. Pulse radar. COMPAGNIE I.B.M. FRANCE. 9 May, 1962 [10 May, 1961], No. 17926/62. Addition to 1,246,791. Heading H4D. In the target selection system 22 of the apparatus described in Specification 1,246,791, the present Specification provides for the selection of echoes by priority (circuit Fig. 5, not shown). It is assumed that the echoes originate from two different sources A and B and differentiation between the sources is effected by known devices. The order of priority established is, first priority, old, confirmed echoes, i.e. echoes detected at least twice; new, B echoes have priority over rear A echoes and unconfirmed old echoes, i.e. echoes for which there was only one detection. Three stepping registers, formed of known trigger circuits are provided separately for the echoes A, B and for confirmed old echoes. Each register provides a delay for the received echo by passage in sequence through five stages. Blockage of a register occurs before the signal reaches the fourth stage, if a signal of higher priority exists in the remaining stages. In the present system, the priority selection is operative over 3 Ás period and a 3À5 Ás delay is provided in each register.

Title: Overload switches having a power storing device
IPC: H01H71/00
Filed: 1920-07-02
Abstract: 146,308. Krupp Akt.-Ges., F. June 21. 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Electro-magnetic cut-outs; protective systems. -Electro-magnetic force tending to open the cutout switch is directly balanced against mechanical force tending to close it, and after the cut-out has operated the switch member is retained in the open position by the preponderance of electromagnetic force due to changed electric connexions. Fig. 1 shows an arrangement for direct current circuits. When the current is excessive, a cutout switch member A<2> is moved against a spring A<3> by the attraction of a series winding A on a solenoid core A', interrupting the main circuit, but remaining in its attracted position owing to energization of a shunt winding A<6>. To allow the cut-out to reclose, a main switch B must first be opened. Alternatively to the main switch B, a hand switch may be placed in the shunt circuit. Instead of a simple shunt circuit, the winding A<6> may be connected to the exciting circuit of a subsidary dynamo, as in a Leonard motor-generator set. For alternating currents, as shown in Fig. 4, a repulsion motor G produces a torque which opens the cut-out H when the current is excessive, the motor field G<3> remaining excited by current from a transformer K<1>. For three-phase currents, an induction motor replaces the repulsion motor. Connexions are described whereby the switch recloses automatically when the part of the net-work which has been cut-out comes into agreement with the other part in respect to phase, frequency, and electro-motive force.
