Abstract: 1,158,793. Pipeline pigs. T. D. WILLIAMSON Inc. 4 Sept., 1967 [26 June, 1967], No. 40370/67. Heading F2N. A cup for use on a pipeline pig 10 comprises a unitary annular structure which is made of polyurethane, of a durometer of from 65 to 85, and has (a) a body portion 13 for fastening, e.g. by engaging a radially extending annular surface, to the pig body 10, (b) a lip portion 15 for sealing and slidingly engaging an inner wall of a pipeline, and (c) a web portion 17 which integrally joins the body and lip portions 13, 15 and which is shaped so as to position substantially all of said lip portion 15 to the rear of the juncture 18 of the web portion 17 with the body portion 13 when the web portion is in the relaxed state, the web portion having a flexing section intermediate said body and lip portions. As shown the pig 10 consists of a hollow cylindrical section 11 which has brushes 12 and a radial flange 10d, to which cylindrical portions 13a of the body 13 are attached by bolts 14, the length of the web 17 being chosen to give the required radial flexure. The thickness "X" of the web 17 should be sufficient to support the pig section 11 and to prevent reversal of the lip 15, the latter being thick enough so that the pressure differential across the cup does not press the lip 15 into excessive frictional contact with the pipe 16. Optimum results are stated to be achieved when the thickness "T" at the juncture 18 is approximately one quarter of the distance "F" between the juncture 18 and inner wall of the pipeline 16 and, when the minimum thickness "X" is about half of the thickness "T".

Title: An electrical selector system
IPC: H04Q9/14
Filed: 1961-11-16
Abstract: 956,302. Electric selective signalling. W. H. SHORT. Feb. 15,1963 [Nov. 16, 1961; Dec. 22,1961; Feb. 7, 1962], Nos. 41094/61, 45976/61 and 4651/62. Heading G4H. An electrical selector system comprises a control unit 1, with an operating switch 7, controlling a loop 6 containing one or more controlled units 2-5, wherein on a first actuation of switch 7, pulses from unit 1 scan one switch in each of units 1-5 in turn ("main-scan"), a second actuation of switch 7 during the scanning of the switch in one of the units 2-5 stopping the main-scan and initiating scanning of a sequence of function switches in the thus selected unit 2, 3, 4 or 5 ("sub-scan"), a third actuation of the switch 7 during a sub-scan setting into operation the function whose switch has just been reached, the sub-scan continuing until the main-scan.is renewed by selecting (by actuating switch 7) a certain function switch (called "transfer" switch). The system can be used for the control of various amenities (list &c. given) by a bedridden patient. The progress of the scanning is indicated by lamps on the units being scanned. Each controlled unit contains a "stop" function switch which when selected stops the pulse generation, and therefore the sub-scan, the latter being resumed when switch 7 is pressed again. The radiogram unit 3 has further sets of switches associated with the function switches, a set being scanned when the associated function switch is selected, to enable control of volume or &c. by selecting one of the set. A priority unit 9 is provided, not in the loop 6, a sub-scan of it being initiated when a "priority" function switch is selected during the sub-scan of one of the units 2-5 of the loop 6, this action terminating the sub-scan of the loop unit. The latter is resumed if a "transfer" function switch is selected during the sub-scan of the priority unit 9. When an amenity controlled by the priority unit 9 is selected, audible devices in the loop 6, which have been set operating, are automatically switched off. A general facilities unit 5 controls a number of amenities, plugged into it, switching one on when a corresponding relay, scanned during the sub-scan of unit 5, is selected. If the relay is selected again, the apparatus is switched off The same applies to the priority unit 9. The system can be switched off by selecting the control unit 1 during a main-scan. The prf of the pulse generator can be varied. The switches which are selected, other than in the main-scan, are the contacts of uniselector-operated wipers. Multicore cables connect the units 1-5, 9, plugging into each, enabling extra units to be added into the loop 6. Fig. 2, (not shown) shows a more complicated system, wherein one of the units in the loop is a distribution unit enabling scanning to be transfered to one of three subsidiary loops, one of these similarly having two further loops appendant to it. Figs. 3-7, (not shown) give various circuit diagrams.

The crimped filaments of a yarn are flattened, and then loaded along a longitudinal stripe at the points of cross-over with the crimps extending laterally therefrom to form a bulked yarn. In one embodiment (Fig. 2,) a yarn 10 is passed, if necessary to restore the crimp through a heated tube 14 and is then flattened between a roll 21 and a fabric shield 22 of for example spun glass and having a lining 23 of heat resistant, low friction material. A wire 24, heated electrically, is held against the shield by a weight 25 so that a longitudinal stripe of the yarn is heated and thus bonded. The yarn is then twisted, by a ring twister, so that the bonded stripe forms the core of the yarn. The hot wire may be replaced by a heated roll with one or two flanges to form, respectively, one or two bonded stripes. In another embodiment, Fig. 7, a cover shield 51 carries a nozzle 52 adapted to direct a jet of hot air, or bonding liquids, on to a stripe or stripes of the yarn. The hot flange(s) may be patterned, or the jets for the nozzle 52 varied to produce a novelty yarn with perhaps the yarn only being bonded at spaced points.

Abstract: 1,036,766. Battery charging temperature sensitive arrangements. HARMER & SIMMONS Ltd. Jan. 22, 1965 [Oct. 22, 1963], No. 41704/63. Heading H2H. A chosen component of battery charging apparatus which heats up with the passage of charging current and cools down upon reduction or cessation thereof, is associated with a temperature sensitive element arranged to initiate a control action when the component temperature has fallen by or to a predetermined value. Fig. 2 shows the application of the invention to a circuit in which a battery at terminals 1, chargeable by a transformer/ rectifier arrangement 4, 5, has its charging current varied by the control winding 18 of a transductor 17 in dependence on a hydrogensensitive resistance probe 16 responsive to battery gassing, the construction and operation of this probe together with circuit members 20, 27, 28, 29 being generally similar to that described in Specification 1,004,786. The temperature-sensitive element comprises a negative temperature coefficient resistor 22 inserted in the windings of transformer 4 and connected as shown with similar resistors 23, 24 providing ambient temperature compensation, a transistor 25 and Zener diode 26 completing the thermal control circuit 21. At high values of charging current the temperature of resistor 22 is such as to make a transistor 19 non- conductive and thus produce a larger charging current than that which would be permitted by the probe 16 alone. Reduction of the charging current upon gassing of the battery reduces the temperature of resistor 22 until transistor 19 becomes conductive, whereupon the above-mentioned effect of the thermal control circuit 21 is diminished thus causing the charging current to be further reduced. In another embodiment, Fig. 1 (not shown), utilizing a sudden reduction in charging current when the battery voltage has reached a predetermined value, the fall in temperature of transformer 4 is detected by a bi-metal switch whose contacts 14 open the holding circuit 11, 13 of the main contactor after a predetermined time to terminate the charging operation. The invention may be applied to the batterycharging apparatus of Specifications 912,664, 912,665 and 912,666.
