Title: Improvements in or relating to Wire-Stranding Machines.
Inventor: GOODFELLOW DAVID SYDNEY
IPC: D07B7/16
Filed: 1967-04-07
Abstract: 1,199,491. Endless conveyers for wire bobbins. BRITISH INSULATED CALLENDERS CABLES Ltd. 5 April, 1968 [7 April, 1967], No. 15993/67. Heading B8A. [Also in Division D1] A conveyer system is used to feed full bobbins to, and empty bobbins from, the loading station 11 of a wire-stranding machine. If the conveyer runs below the central axis of the machine, the bobbins are raised and lowered into and out of the machine by one, or a pair of, pneumatic rams 16 operating through spaces in the conveyers. If, as shown, the conveyer runs alongside the machine, a bridging conveyer 12 which is capable of sideways movement is provided to move full and empty bobbins into and out of the loading station 11. The bridging conveyer may return the empty bobbins to the main conveyer or to a second conveyer. In a first embodiment the bridging conveyer moves sideways from the main conveyer 10, unloads the bobbin from the machine. It returns to the conveyer 10 to pick up a full bobbin and simultaneously unload the empty bobbin, then moves back to the loading station with the full bobbin to load the machine. In a second embodiment the bridging conveyer is first loaded with full bobbins from conveyer 10, moved sideways into the loading station 11, receives a further (empty) bobbin from the machine, and then moves forward to bring a full bobbin into the loading station and load the machine. The remaining empty bobbins of that part of the machine are then replaced similarly, and the bridging conveyer is moved away. As illustrated in Fig. 3, the bridging conveyer moves sideway on rollers 27, 28 under the action of pneumatic cylinder 32. The endless chains of conveyer 12 can be moved by motor 23 which may be mounted on the conveyer. The bobbins may be moved up and down by the rams at an angle of 30 degrees to the vertical. Two or more loading stations may be serviced simultaneously. The empty bobbins are returned for rewinding by an extension of conveyer 10 which runs in a loop around the end of the machine.

Abstract: 561,476. Switching systems. FARLAM, G. S., BOURNE, R. A., and BURGESS, L. B. Nov. 17, 1942, No. 16225. [Class 38 (iv)] [Also in Groups XXXVI and XL] A current regulating resistance consists of a mixture of screened carbon dust and powdered insulating substance, such as silica, within a container of insulating material, the mixture extending between terminals provided at each end of the container. A metal tubular container A, for example, of iron or steel, has a tubular lining B of refractory material closed at its ends by metal plugs C<SP>1</SP>, C<SP>11</SP> with integral shanks D<SP>1</SP>, D<SP>11</SP>. The lower plug C<SP>1</SP> has an extension E<SP>1</SP> of reduced diameter over which is slipped an inner refractory tube F. The lining B with its plugs C<SP>1</SP>, C<SP>11</SP> is spaced from the container A by insulating collets G<SP>1</SP>, G<SP>11</SP>. The container A is closed at the ends by caps H<SP>1</SP>, H<SP>11</SP>, from which the shanks D<SP>1</SP>, D<SP>11</SP> are insulated by micanite tubes I<SP>1</SP>, I<SP>11</SP>. The space between the lining B and the inner tube F is filled with a mixture J of screened carbon dust and silica powder. The extension E<SP>1</SP> within the inner tube F supports a mercury cathode K, while a similar extension E<SP>11</SP> of the upper plug C<SP>11</SP> carries a carbon preferably metallised, anode L. The space between the cathode K and anode L is evacuated of air as, for example, by fusing magnesium wire connected between the extensions E<SP>1</SP>, E<SP>11</SP>, or through an evacuation tube. The container A is provided with heat radiating fins N<SP>11</SP> at its upper part and similar fins N<SP>1</SP> at its lower part, so that the upper end enclosing the anode is kept cooler than the lower end enclosing the cathode. Terminals O are secured to the shanks D<SP>1</SP>, D" by nuts P. The resistance is connected in series with the circuit to be controlled and with a starting switch. The powdered mixture J owing to its cold resistance, limits the starting current and gradually heats up, reducing its resistance and vaporizing the mercury cathode K. An arc is struck between the anode L and cathode K and short-circuits the mixture J. Striking of the arc may be facilitated by an auxiliary anode in the vicinity of the cathode or by a condenser across the terminals. The metal-vapour discharge device may be omitted and the column of carbon-silica mixture reduced in length. In this arrangement there is a gradual reduction of resistance under the influence of rising temperature followed by a sudden decrease in resistance due to temporary breakdown. The high-resistance condition is restored when the circuit is opened and the column allowed to cool. The silica may be replaced by ceramic. The mercury may be replaced by cadmium or any of the metals or mixture of metals used in metal-vapour discharge lamps.
