Title: Improvements in or relating to cantilever structures for overhead electric traction systems
Inventor: RIGNALL NORMAN ROBERT
IPC: B60M1/20
Filed: 1961-01-25
Abstract: 933,972. Supporting overhead conductors. BRITISH INSULATED CALLENDER'S CABLES Ltd. Jan. 24, 1962 [Jan. 25, 1961], No. 2935/61. Class 36. The invention is concerned with a novel tie member 2 (Fig. 4) for a cantilever support for an electric traction system contact wire. The support system comprises a mast or other vertical support member 31, a horizontal tie member which comprises a tension insulator 35 and a tie bar 2 constructed according to the invention, and an inclined strut formed of a metallic member 29 and a porcelain insulator 30. Bracket 33 carries a catenary suspension clamp and further down the strut is a registration arm 27 carrying an adjustable drop bracket 37 and a steady arm 38 for the contact wire. The tie bar, shown in detail in Fig. 3, consists of a male member 2 with an eye bolt 17 at one end sliding in a female member 12 also carrying an eye bolt 3. At one end of the female member is a rectangular block 4 which houses an eye bolt through which the male member passes. When a nut is tightened the lower part of the eye bolt is drawn into one of notches 21 on the lower side of the male member to clamp the male and female member together. The end of the male member is provided with sideways lugs 16 which slide on runners 13 provided in the bottom of the female member, and engage the block 4 to prevent the male and female members separating if the clamp fails. The male may be withdrawn by pushing the male member right in when the lugs 16 pass through the runners 13, rotating the male member through 90 degrees and withdrawing it through the eye bolt. The female member is a galvanized iron casting and the male member 5 is of forged steel. A further embodiment is described in which the female is a circular tube with a slot in it in which a stud on the male can slide. A nut on the stud can clamp male and female together. The end of the slot is circumferential so that if the clamp fails the stud strikes the circumferential portion. The slot then runs axially again so that by relative rotation male and female may be separated.

Title: Improvements relating to plant for the separation of materials from one another
IPC: B07B4/04
Filed: 1932-02-01
Abstract: 382,153. Pneumatic separating. NORTON, B., Sandford Hall, Claverley, near Wolverhampton, and COLLINS, J. N., 24, Bishop Street, Birmingham. Feb. 1, 1932, No. 3004. [Class 117.] In apparatus for separating materials of different mass and size, such as coal and dust, of the type in which the mixed material is presented in a number of thin streams and is subjected to the action of a gaseous current passing therethrough which carries off the lighter ingredients, provision is made (a) for preventing the escape of dust into the atmosphere and (b) for regulating the strength of the air-current in the separating chamber while maintaining the volume of air passing through the fan. In order to suppress the escape of dust, the separator is included in a circuit with a fan 6 and dust collector 8 and is enclosed in an air extraction hood 4 and an air supply hood 11. At one point in the circuit, preferably after the dust-collector 8, part of the air is byepassed through the pipe 12 and filter 13 to the atmosphere, and make-up air is thus positively induced into the circuit at the apertures provided for charging or discharging the separator. To regulate the air current in the separator, independently of the fan, a byepass 15 connects the hoods 11, 4 and is provided with a valve 16. In the embodiment of the invention illustrated the separator comprises a number of shelves over which the material falls in cascades. Under each shelf is disposed a valve-controlled nozzle 3 by which the air is directed through the materials. The fan 6 is disposed in front or in rear of the dust-collector. In a modification, Fig. 3 (not shown), the separator may consist of a horizontal jigging device formed with inclined shelves and air spaces.

Filed: 1967-05-11
Abstract: 1,174,986. Pronged fasteners. THOMAS WALKER Ltd. 7 May, 1968 [20 Jan., 1968], Nos. 21825/76 and 3138/68. Heading B4C. [Also in Division A3] A machine for attaching pronged fastener members of garment fastening devices to garment material e.g. a make-up pocket in a trouser waistband, comprises downwardly facing upper lies (38), (38), Fig. 7 (not shown), and upwardly facing lower dies 50, 50 which are movable upwards by plungers 51, 51. In operation the upper dies are located in a pivotable arm 36a and are loaded with back-plates 11 from stacks 84, 84 by a reciprocable feed slide (86), Fig. 5 (not shown), and are held in position by a blade spring 47. The lower die is fed by a vibrating drum 76 and a channel 75 with pronged fastener members such that the prongs face upward. From the channel the pronged members pass through a transfer slot partly curved by a locating spring blade 80 in a fined guide plate 81 and are fed automatically into die recesses 66, 66 each time the latter is emptied and the die returns to the loading position. A spring biased jaw member 69 holds the pronged members in position during upward movement, and is released by engagement with a cam 70. When the dies are loaded arm 36 is pulled down via a chain 42 and the made up pocket is slipped on to it. The arm is then released and re-engages under frame portion 37. Plungers 51, 51 are now operated via levers 99, 99 so that the attachment operation is completed. As a safety device, a control valve 100 has to be operated simultaneously with plungers 51, 51. In a modification the arm 36 may be slidably mounted on vertical guide posts or pins towards its inner end. In a further embodiment, Figs. 9 and 10, (not shown), back plates are retained in an upper die (200) by a spring loading finger (205). Instead of an arm for supporting the garment material a flat platform (220) extends forwardly and is pivoted by rearwardly extending arms to a fixed head part. The platform is also guided by a hinged depending skirt panel (222). Movement of a vertical plunger (214) is controlled simultaneously by a lever arrangement which is connected to the plunger that operates the feed stroke for the back plates. Thus only one control movement initiates a full cycle of operation.

Title: Diisocyanate-modified polyester elastomers
IPC: C08G18/10
Filed: 1954-02-08
Abstract: In the preparation of elastomers by reacting diisocyanate-modified polyesters with glycols, a glycol is employed which contains the group -NH.CO.NH- or > N.CO.NH2 between the hydrocarbon radicals carrying the hydroxy groups, these radicals containing at least two carbon atoms.  The urea glycol may be used in a quantity insufficient to react with the isocyanate groups of the polyester or alternatively in larger quantity in which case 1-5 per cent by weight of the product of a diisocyanate is added prior to moulding.  The product may be worked in the liquid state and removed from the moulds shortly after shaping, the curing being completed out of the mould.  The initial polyesters may contain minor proportions of amide links. In examples: (1) 200 grams of a glycol-adipic acid polyester of hydroxyl number 56 is reacted with 35 grams 1.5 naphthalene diisocyanate; 6.6 grams N,N1-b -di-(hydroxyethyl) urea are added at 130 DEG  C. with stirring and the melt cast into moulds.  The product is removed after 10 minutes and cured at 100 DEG  C. for 24 hours; (2) as in (1) but using 38 grams diphenylmethane diisocyanate; (3) as in (2) but instead of casting the material is rolled and shaped under pressure after the reaction is completed; (4) glycol-adipic acid polyester reacted with diphenylmethane diisocyanate and the product reacted with N,N1-dihydroxyethylurea in an amount equivalent to the free isocyanate groups.  The product is shaped after incorporation of 1.5 naphthalene diisocyanate by rolling.  Specification 700,608 is referred to.ALSO:N,N1-di-(hydroxyethyl) urea may be obtained by reacting oxazolidone and ethanolamine or by boiling ethanolamine and urea in acid solution.  N-di-(hydroxyethyl) urea may be obtained by reacting diethanolamine with potassium cyanate.  Compounds containing the urea group twice in the molecule may be obtained by reacting ethylene diamine with two mols. of oxazolidone.  Ethanol-butanol ureas are also referred to.

Abstract: 1,119,863. Viscosimeters; measuring liquid level electrically. TECHNICON INSTRUMENTS CORP. Jan. 27, 1966 [Feb. 23, 1965], No.3643/66. Headings G1N and G1S. The viscosity of successive samples of blood is measured by determining the pressure needed to pump the samples at a constant velocity through an aperture. The samples are drawn in succession from a rotary sampler 10 by a peristaltic pump 12 and forced via pipe 14 through a constriction 38. Depending upon the viscosity of the particular sample, some blood will rise up tube 44 thereby displacing water which has been trapped between the upper part of tube 44, a capacitance transducer 90, and a tube 110 which contains air and is sealed at the upper end. The displaced water rises between a pair of plastic coated metal plates 92, 94 of the transducer 90, and the change of capacitance is measured in an undisclosed manner by a bridge circuit recorded as a measure of viscosity. Between successive blood samples, a programmer 116 causes solenoid valves 58, 84 to rotate from the positions shown so that water can drain from the transducer 90, and water can be pumped by a line 16 from a source 32 to flush the tube 44, and water is also supplied through pipe 14 instead of blood.

Abstract: 368,934. Wireless receiving circuits. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, CLARK, F. and COLLYER, J. E., of General Electric Co., Ltd., Stoke, Coventry. Feb. 5, 1931, No. 3650. [Class 40 (v).] In a system for distributing broadcast programmes wherein a receiving station containing a plurality of wireless receivers supplies programmes to a plurality of substations each of which serves a group of subscribers, a subscriber may select any desired programme by means of a selecting device which is operated by dialled impulses transmitted over the subscriber's line wires. The amplifiers supplying the programme bus-bars WX, YZ are only rendered operative if one or more subscribers require a programme. When the switch SW is in a selecting position, circuit is closed over wiper of bank SW3 to the selected bus-bar U or V which is connected to relays controlling the operative condition of the amplifiers. Fig. 3 shows an arrangement for maintaining the volume constant irrespective of the number of subscribers receiving programmes. The lines JL incoming from the main station supply a thermionic valve of the " variable u" type which normally is biased negatively by resistance R1. When a subscriber dials on to the corresponding bus-bars a resistance R2 is connected over wiper SW4 in parallel with resistance R1 to reduce the bias and thus increase the amplification factor. Further resistances are switched in parallel with the resistance R1 according to the number of subscribers using the bus-bars to correspondingly increase the amplification and maintain the output to each subscriber substantially constant. In an alternative arrangement the busbars are directly supplied, and an amplifier individual to each subscriber is connected on the subscriber's side of his selector switch.
