Title: Device for controlling the unwinding of strip material in coil winding apparatus
Inventor: WHITEMAN BENTON ADAIR
IPC: H01F41/06
Filed: 1968-09-23
Abstract: 1,235,169. Winding webs. REYNOLDS METALS CO. 23 Sept., 1968 [29 Sept., 1967], No. 45159/68. Heading B8R. In apparatus 32 for winding electrical stripconductor coils 25, the unwinding of the strip 27 from a supply roll 34 is controlled by a freely rotatable roller which is biased against the supply roll 37 so as to be rotated thereby and which is provided with a brake arrangement 28 for controlling and stopping rotation of the roller to provide controlled unwinding of the strip under substantially uniform tension and prevent the supply roll 34 from overrunning. The roller is carried by a swinging arm 154 which is biased towards the roll 34 by a spring-loaded arm 165 or by a fluidoperated actuator (Fig. 17, not shown). A brake shoe 162 mounted on the arm 154, together with a plunger assembly 180 (Fig. 11, not shown), co-operates with a brake drum 161 associated with the roller and the assembly 180 is adjusted so that the shoe 162 is held against the drum 161 in a precisely controlled manner whereby the tension in the strip 27 is maintained constant. An arrangement 62, including a roller 61 and a further roller 63 carried on a swinging arm, senses any reduction in tension in the strip 27 produced, for example, by an abrupt slow down or stopping of the winding operation and, by way of an operating rod 195, acts on the assembly 180 to urge the brake shoe hard against the drum 161 so that over-running of the supply roll is prevented. For winding the coils 25 the apparatus 32 is provided with a rotary table 39 which can be indexed to three positions 45, 46, 47 and which carries three fluid-operated actuators 40, each having a rotatable mandrel 42 carried by a telescoping rod 41. At position 45 of the table 39 the associated mandrel 42 is extended to engage an empty core 26 contained in a hopper 36 ; the mandrel is then retracted, the table is indexed to position 46, the mandrel is engaged by a drive shaft 53 and the coil 25 is wound. When winding is complete, the table 39 is indexed to position 47 and the coil 25 is stripped from the mandrel 42 by members 54 for feeding to a collection table 60. A device 29 operates to continuously reposition the supply roll 34 axially along its supporting shaft so that the strip leaves the roll in a fixed vertical plane, this control enabling easier forming of the coil 25.

Abstract: 1,099,505. Parametric frequency changers. GENERAL ELECTRIC CO. Ltd. Nov. 4, 1965 [Nov. 9, 1964], No. 45539/64. Heading H3B. A microwave frequency changer uses a varactor diode contained in a waveguide section 3, Fig. 1, to modulate a microwave signal (f> 10<SP>3</SP> Mc/s.) from a source 1 with a lower frequency, frequency-modulated, signal from a source 2, one side-band of the resulting modulated signal being selected by a waveguide filter 4 as an output to an aerial 5, and a part of the signal rejected by the filter being reflected back to the diode in a phase appropriate for it to be reconverted into the required side-band, the overall power loss between the microwave source and the output being less than 5 db. It is stated that without reflection the power loss must exceed 6 db. Reflection of side-band components back to the microwave source 1 is prevented by a narrow band waveguide filter 6. The waveguide section 3 is described in detail, Figs. 2 and 3 (not shown). Within this section is mounted a vertical T-shaped bar (11), opposite arms (19), (20) of which are each one quarter of a wavelength long at the frequency of the source 1 so as to serve as a microwave signal choke and termination respectively. The choke arm is extended so as to form part of a coaxial line connector (24). The varactor diode (27) is carried by a screw (29) adjustably mounted in a holder (26), and has a pin engaging spring fingers (28) in the branch arm (25) of the T- shaped bar. Matching for maximum microwave power at the diode and to optimize the power of the sideband components is effected by screws (30).
