IPC: D02H13/16
Filed: 1955-12-08
Abstract: 797,700. Warping yams. ALGEMENE KUNSTZIJDE UNIE N.V. Dec. 8, 1955 [Feb. 11, 1955], No. 35324/55. Drawings to Specification. Class 142(1) To avoid imperfect fabric due to varying lustre and affinity for dyes in artificial threads when collected in a spinning centrifuge, or on a spool, or on a thread package obtained from an after-twisting process (such packages being subsequently termed "primary" packages) the warping is carried out directly from these primary packages. The warping comprises the following steps (a) dividing each package into lengths each equal to the length required on the warp beam, (b) forming a number of thread bands in which each band comprises one thread from each package and all the threads in it come from a corresponding part of the packages, (c) winding the bands consecutively on to the warp beam in the same sequence as the threads in them had in the packages.

Title: Improvements in film feed mechanism for roll-film photographic apparatus
IPC: G03B19/04
Filed: 1922-12-29
Abstract: 195,351. Huber, A., and Simons, W., (Assignees of Kucharski, S.). Nov. 6, 1922, [Convention date]. Cameras, roll - film.- In roll-film apparatus the film is advanced by pulling forward a draw-bar b which rotates the, take-up spool c<1> through a flexible band k and a ratchet drum g, the stroke of the draw-bar being progressively reduced on each successive operation to maintain a constant feed of film. The band k and 'bar b are returned by a coiled spring on the axis of the supply spool c, and the spool c<1> is prevented from rotation during the return movement. The amount of film fed forward is limited by the engagement of a pin s on the bar k with an arm r. In the return movement, a pawl on the bar b operates a counter disc m. In order that the same length of film may be advanced as the film on the spool c<1> increases, a cam p on the counter disc m is advanced on each stroke, and adjusts. the position of the arm q, to which the arm r is pivoted.

Filed: 1974-08-15
Abstract: 1533221 Analogue to digital conversion HAWKER SIDDLEY DYNAMICS ENG Ltd 17 Nov 1975 [15 Aug 1974] 35956/74 Heading H3H An a-d and d-a converter circuit comprises a V.C.O. which outputs a frequency dependent on its input value. In converting a voltage on line I to digital output from a counter IS, multiplexer 2 passes the voltage to the oscillator which outputs a frequency via clocked gate G3 to the counter. In this mode either of two feedback routes, via gate G1 and frequency#analogue converter 7 or via frequency divider 10 and gate G2 may be used, the second extending the range of the converter. Amplitude modulated frequency input is halfwave rectified in the multiplexer and converted in a similar manner. Frequency modulated input is applied to multiplexer 16, then to a phase comparator 11, which is in a phase locked loop comprising the divider 10 and input multiplexer 2, this stabilizes the V.C.O output as a multiple of the input frequency, the gate G3 and counter integrating this to give a digital output. In its d#a mode a reference frequency 17 derived from clock 13 is applied to the multiplexer 16 and the phase locked loop stabilizes at frequency dependent on the ratio set in divider 10 by the digital input. A f.m. output is obtained at 20 and a d.c. output at 19.

Abstract: 1,129,844. Endless conveyers. GENERAL ELECTRIC CO. Ltd. 27 Sept., 1967 [11 Aug., 1966], No. 36061/66. Heading B8A. Bricks 8 are conveyed in sequence by endless bands 6 on to an air cushon above a perforated plate 9 where each is momentarily halted and oriented by a roller 12 suspended by a counterweight 18. The latter is so adjusted that the following brick (not shown) pushes the former so that it upwardly deflects the weight 18 and moves on to endless belts 5. The orientation of the brick on the plate 9 results in the interruption of air jets in the plate 9 which are normally operative upon fluid-actuated switch devices 27 and 29. These form part of a logic NOR arrangement which causes arms 22 to swing inwards and position the brick laterally by rollers 19 1 , 19. When the brick is pushed onwards, its leading edge interrupts a third jet 28, and this causes retraction of the arms 22.

Title: Electric motor speed control systems
IPC: H02P7/18
Filed: 1955-12-16
Abstract: 797,559. Control of D.C. motors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 16, 1955 [Dec. 21, 1954], No. 36108/55. Class 38 (3). A paper-drive motor on a business machine such as a high-speed lister is operated at a first speed by connecting its armature 10 and field winding 11 in series to a low-voltage source 14 through an adjustable resistor 19, the armature of the motor being shunted by an adjustable resistor 20. To accelerate the motor, a switch 16 is closed to energize relay 12 whereby the motor is connected to the high-voltage source 15 and the resistors are removed from the motor circuit. To prevent the motor from exceeding a predetermined second speed, the armature voltage is applied through resistor 17 to the coil of relay 13, so that, as soon as capacitor 18 is sufficiently charged, relay 13 is actuated. This causes the armature to be shunted by resistor 21 and introduces the resistor 22 in series with the armature and field winding. The motor is braked by opening the switch 16 to de-energize the relay 12, the field winding 11 being initially excited from the low-potential source 14 through resistors 19, 21 and 22 so that the armature develops sufficient voltage to keep the relay 13 closed. The closure of contacts 12a, 12d now connects the armature and field winding in series with resistor 20 between the highpotential source 15 and earth, resistors 21, 22 being connected in parallel with the resistor 20. The polarity of the armature is reversed so that reverse-current braking is obtained until the armature voltage is reduced to a value allowing release of the relay 13, whereupon the original first-speed circuit is afforded with the motor operating from the low-potential source 14. A momentary increase in the speed of the motor is prevented after the completion of the second phase of the braking operation by the provision of resistor 23 and capacitor 24 which allow the field winding 11 to be energized from both the sources 14 and 15 for a predetermined time interval after the motor decelerates to the first speed. A rectifier 32 prevents current-flow, due to the difference in potential of the sources 14 and 15, upon the closing of relay contacts 12b. The resistor 19 may be dispensed with, speed control being assisted by the use of governorcontrolled 'contacts in series with resistor 20. These contacts open momentarily when the motor speed falls below the predetermined first value.
