Title: Improved method and apparatus for forming or shaping sheet strips
IPC: B21D5/06
Filed: 1958-09-17
Abstract: 887,934. Drawing. MAIER, M. Sept. 17, 1958 [Aug. 25, 1958], No. 29815/58. Class 83 (4). A method of forming and shaping sheet strips, for example to make guttering, comprises feeding and forming the strip by a drive means including a reciprocated slide, movement of which in one direction effects the feed of the strip, forming of the strip being effected during movement of the slide in the other direction while the strip is held against movement. Strip 8 to be formed passes through edgeforming members 52, 53 and 12 then through edge-forming members 58f and 58w which complete the formation of a water bead f and a reinforcement bead f<SP>1</SP> and over a former 17, flat at its forward end and of U-section at its rearward end which serves to curve the central part of the strip 8. The former 17 is secured to the machine frame, while the members 52, 53, 58f and 58w are connected together by flexible arms 60 and cross members 58a, 65 to form a slide unit 58 which is reciprocated longitudinally of the strip 8 in guides 64 by a connecting rod 57 reciprocated by an eccentric driven by a motor 48. The members 58f, 58w incline inwardly and downwardly towards the exit end of the machine so that on their forward movement they pull the unformed strip 8 into the machine and push completed guttering 7 from the machine. A member 49 may press the strip 8 towards the former 17. When the members 58f, 58w move rearwardly, pivoted brake shoes 9, 13, 14 on cross beams 2, 3, 5 supported on rods 43 pivoted within hollow legs 6 of the machine prevent rearward movement of the strip 8. The shoe 9 may be locked out of operation by a latch 2a. The members 52, 53, 58f, 58w as they move back along the strip 8 shape its edges and, as a consequence of the orientation of the members 58f, 58w relative to the fixed former 17, form the strip over the former. Lubricating funnels 51 are provided on the members 52, 53.

Title: Improvements in or relating to electric circuit control arrangements for lifting magnets
IPC: B66C13/18
Filed: 1931-10-28
Abstract: 382,426. Electromagnets. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Hodgson, H. E. ; Wauwatosa, Wisconsin, U.S.A.) Oct. 28, 1931, No. 29883. Convention date, Oct. 30, 1930. [Class 35.] In a control arrangement for quickly de-energizing a highly inductive device such as a lifting electromagnet involving the discharge of the electromagnet through a resistance and a subsequent temporary flow of reduced current, in the reverse direction through the magnet winding, the flow of reverse current is controlled by an electromagnetic, switch energized by current in the discharge path. As shown in the Figure, a discharge resistance R<1> is initially connected across the lifting magnet winding through contacts 2d of a main contactor 2. On energization of the winding 2a by closure of a master switch 4 the discharge circuit is broken and an energizing circuit directly across lines L<1>, L<2> is completed at contacts 2b, 2c. When the master switch is opened and the relay 2 de-energized the discharge circuit is again completed and a portion of the discharge current flows through the winding 3a of an electromagnetic contactor 3 which establishes at its contacts 3b, 3c a circuit in the winding 1 in the reverse direction, the reverse current being limited by resistances R<2>, R3. This circuit is maintained until the current in the discharge circuit dies down to a value insufficient to maintain the relay 3 in the operated position when the magnet 1 is finally disconnected from the supply. The winding 3a of the contactor 3 may, alternatively, be placed in series with the discharge resistance R<1>.

Abstract: 538,827. Coating cables by extrusion. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd., DEAN, J. N., and WEBSTER, J. Nov. 13, 1939, No. 30004. [Class 87 (ii)] [Also in Group XXXVI] Thermoplastic insulation is treated in the plastic condition in vacuo on its way to, and while being applied to, the conductor, so as to remove voids and occluded gases. Figs. 1 and 6 show alternative means for treating the insulation and Fig. 7 shows a means for leading the conductor to the point where the insulation is extruded thereon from the means shown in Fig. 1 or 6. The screw-type forcing machine A is connected by a pipe B to a heated die B' which is flared in the direction normal to the plane of the drawing so as to produce a ribbon C of plastic material which is passed by feed rolls E in a vacuum chamber D through the pipe G to another extrusion machine F, which is shown as a gear pump mechanism but may be similar to A. The solid material passes to a heated die H and through ports J whence it passes to the die proper for application to the conductor. In Fig. 6 vacuum chambers D, D and rolls I, L, M are provided for passing the material to a screw extrusion device O, boats P being provided in both Figs. to seal the passage of the material from the rolls. In Fig. 7, the material is fed through orifices 2 to the die 1 which is connected with the die H or O of Fig. 1 or 6. The conductor passes through one or more sets of dies 13 screwed to plates 12 which in turn are screwed to walls of high-vacuum chambers 7, 8, which, as also the parts A, B, F of Fig. 1, may be either steam or oil-jacketed or electrically heated.

Filed: 1958-09-19
Abstract: 838,201. Testing fabrics. KRANTZ, H., and KRANTZ, W., [trading as KRANTZ SOHNE, H.]. Sept. 19, 1958, No. 30094/58. Class 42 (2). [Also in Group XL (b)] In a device where the number of weft threads in a travelling fabric is counted by means of a lamp and photo-cell, a shutter revolving at a speed proportional to the speed of travel of the fabric controls the start and finish of the count so that the number of threads per unit length can be seen. In the Figure the count of pulses from the photo-cell 3 is started and stopped by pulses from a further photo-cell 10 behind a revolving shutter 8. These latter pulses follow too quickly for the counter to return to zero and a steady count is displayed. To avoid sudden fluctuations due to local irregularities in the fabric it is preferred to use a three-digit counter operating over a distance ten times the unit of length, the units figure of the counter 5 being blacked out. The counter should then start at " 5 " instead of " 0 " so that " 1 " is carried over to the tens figure for thread numbers of 5 to 9. The feed of the fabric, e.g. to a tentering frame, can then be controlled to maintain the thread number constant. A second counter can be installed at the entry end of the machine to indicate or regulate, e.g. degree of shrinkage.

Abstract: 1,157,207. Measuring attenuation. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 4, 1967 [July 7, 1966], No.30678/67. Heading G1U. The attenuation produced by a network A is determined by a system, including a controllable attenuator B, in which during a first time period t 1 , a capacity C 1  is charged in response to a signal transmitted through the network while a second capacitor C 2  is charged in response to a reference signal. The charges on the two capacitors are then compared during a second time period t 0  the comparison result being shown on an indicator. The capacitors are finally discharged during a third period. The operating sequence is determined by closing the switches S 1 , S 2  for the time t 1 , by closing the switch S 5  for the time t 2  and the switches S 3 , S 4  for the time t 3 , under the control of a timing unit T. In the series arrangement shown in Fig. 2 the second capacitor C 2  is supplied from a separate reference voltage source I 2  which is adjusted, with the test network short circuited and with the attenuator B adjusted to maximum attenuation, so that the comparator stage gives zero output during time period t 2 . The attenuator is then adjusted with the network in circuit so that the comparator again gives zero output. This may be achieved automatically using a phase sensitive control stage F, which responds to the polarity of the difference between the voltages on the capacitors C 1  and C 2  to step the attenuator in the appropriate direction. D is a diode arrangement enabling C 1  to be charged during both half cycles of the input supply. Alternatively the test network A and attenuator B may be arranged in parallel relative to the test voltage source E with no separate reference source Fig. 1 (not shown). The signal from the source E through the network is used to charge capacitor C 1 , while that from the source through the attenuator is used to charge C 2 , during the first time period. The charges on the capacitors are then compared, in the second time period, and the attenuator adjusted so that, after repeated test cycles, zero difference is achieved.
