Title: Improvements in or relating to protective arrangements for transformers
IPC: H02H3/02
Filed: 1936-05-15
Abstract: 475,130. Protective cut-out arrangements. STANDARD TELEPHONES & CABLES, Ltd., and STOCKS, H. R. May 15, 1936, No. 13814. [Class 38 (v)] A transformer T or other circuit is protected by means of a pair of contact-carrying bimetal springs S, to each of which is connected one end of a heating coil W carrying the main current. When the current rises to such a value as would overheat the transformer, the springs bring the carbon contacts C into engagement with one another, so blowing the fuse F, whereupon the contacts separate and the device is ready for further operation when the fuse is replaced. One spring may be replaced by a fixed strip. Numerical figures for the springs and coils are given for a transformer of circa 50 VA. rating.

Title: Method and apparatus for winding yarn
Inventor: JOHNSON BRYAN KINGSLEY
IPC: B65H54/38
Filed: 1964-04-04
Abstract: A method for producing conically ended yarn packages by over-end winding, in which the axis of the traversing device-e.g. ring or cap-is inclined to the bobbin axis so that a sinusoidal wave-form is superimposed upon the closely-wound helical turns and consequently there are predetermined points during the formation of the package in which patterning or ridging occurs, comprises abruptly increasing the spindle speed at these points to reduce the extent of the ridging. In one embodiment a "long-to-short" package is obtained by the ring being reciprocated between two microswitches which reverse the direction of travel of the ring and which are moved towards one another by cams during the winding of the package.  The speed of the spindle is varied by a cam which either varies the diameter of a pulley in a belt drive to the spindle, or varies the setting of a potentiometer in the electrical circuit of the spindle motor.  The cam has protrusions which cause the spindle speed to be sharply increased at the predetermined points.  The protrusions are preferably empirically positioned on the cam surface.  However apart from these protrusions the cam may be shaped so that the yarn is wound at constant tension, or so that the traveller moves at constant speed or to counteract the fact that the "air retraction" of synthetic linear polymer yarns is generally greater for yarn taken from the inside and outside of the package than for yarn taken from the middle, by decreasing the spindle speed at the start and finish of winding, or to control the twist insertion rate, the yarn denier, or the initial modulus of elasticity.

The scanner 12 at the transmitter contains a photo-electric cell and is connected to a valve 20 which controls the rate of charge and discharge of a condenser 26 in dependence on the depth of shade of the message at the point being scanned. At each charge of the condenser 26 a signal pulse is passed by a neon tube 23 to a transformer 24 connected to a signal transmitting apparatus 29, 30 through an amplifier 27 and a modulator 28. The amplifier 27 is also connected to a halfwave rectifier 32 with a load resistance 31 connected to the primary of a transformer 33, the secondary of which is connected through a rectifier 34 to a coil 11. Each rectified signal pulse causes the coil 11 to release a detent 7 and allow the drum 1 to be rotated one step by a motor 3 to scan the next point of the message. At the receiver, the modulated signal is received by the signal receiving apparatus 35, 36 and fed by a transformer 37 to a full-wave rectifier 40 which yields a signal pulse corresponding to the signal pulse passed by the neon tube 23 of the transmitter. This signal pulse is supplied to a neon tube 16 on the scanner 12 and also to a rectifier device similar to that of the transmitter for controlling a similar coil 11 to release the detent 7 to allow the motor 3 to rotate the drum 1 in steps at the same rate as the steps of the transmitting drum.

Title: Improvements relating to arrangements for automatically tracing calls backwards in automatic telephone systems
Inventor: DRAKE BERNARD
IPC: H04Q3/00
Filed: 1965-04-05
Abstract: 1,078,778. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 23, 1966 [April 5, 1965], No. 14411/ 65. Heading H4K. In an arrangement for tracing connections backwardly over a switch train, as in the case of malicious calls, an outband marking current, e.g. 20 kc., is applied to the line wires at the called end, and a uniselector having access to the group selectors hunts for the marking. For lines subject to malicious calls, a relay (PW) interposed in the private wire at the 1DF energizes in series with the cut-off relay to prepare the call-tracing equipment. Plug and jack connections of the line wires are made at the main frame to a differential relay (CTR) which may be operated by the actuation of an earthing key (KBB) at the substation. In consequence a tape recorder (REC) is switched in to record any speech received by a monitor amplifier (AMP) and also time announcements, and at the same time the marking mentioned above is applied to the line wires. The hunting uniselector (SU) is started, and when the marking is picked up lamps are lit to identify the first selector as well as an attendant's lamp, and the connection is held independently of the calling loop. The arrangement is designed to avoid any clicks or other audible signals which might warn the caller. In the case of a call incoming from another exchange, the tracing equipment identifies the incoming selector and sends a number indicative of the incoming junction over a different junction to the originating exchange, where similar tracing equipment responds and enables the connection to be traced back at that exchange.

Abstract: 821,741. Porous slag. ENERGIE-VERSORGUNG SCHWABEN A. G. May 8, 1957 [May 19, 1956; March 9, 1957], No. 14698/57. Class 22. Porous slag is manufactured from acid vessel slag by cooling the liquid slag in a series of stages, comprising first reducing the temperature of a liquid slag stream to a level at which dissolved gases are freed, the viscosity in this first period being in the range of from 2.10<SP>4</SP> to 8.10<SP>4</SP> poise up to 2.10<SP>7</SP> to 10<SP>8</SP> poise, reducing the temperature at an accelerated rate in a second period until a viscosity of 109 poise is reached, slowly reducing the temperature in a third period over a viscosity range of 109 to 1013 poise, and finally reducing the temperature in a fourth period to obtain a glass-like porous product of viscosity above 10<SP>13</SP> poise. For a specified slag composition, temperatures of 900‹C., 700‹C., 560‹C., and 490‹C., correspond with the viscosity values of 2.10<SP>4</SP> to 8.10<SP>4</SP>, 2.10<SP>7</SP> to 10<SP>8</SP>, 109 and 1013 poise respectively. In Fig. 1, a stream 2 of acid vessel slag flows down a shaft 1 towards an endless conveyer 5 running over rollers 3, 4 in an airtight channel 6. Material acting as nuclei for gas bubbles e.g. wood-flour, brick- or tiledust, and also a combustible material e.g. coal powder or oil mixed with coal, shale, clay, rock or gangue, can be introduced into the stream 2 by devices, not shown, at a slag temperature 1300‹C., the slag cooling to 900‹C. upon reaching the conveyer. Water and/or air from nozzles 7 and 8 cool the slag on the conveyer 5 from 900‹C. to 700‹C., a shaft 11 serving to remove freed gases. The slag, now viscous, is cooled from 700‹C. to 560‹C. around the roller 4 by water or pressurized air, and jumps off automatically from the conveyer or is remove by a stripper 12. The slag is cooled from 560‹C. to 490‹C. in a shaft 16, the lower end of which dips below the level of water in a basin 17, the completely cooled slag being removed by a conveyer 18. Shaft 19 and basin 20 constitute a safety device whereby slag may fall directly from stream 2 to be quenched by water in the basin 20.
