Classes 120 (1) and 120 (3). A device located between calender rollers of a sliver forming machine and a coiler and arranged pneumatically to sever the sliver when a can is full followed by reintroduction of the sliver to the coiler tube when an empty can is positioned beneath the coiler has an air nozzle 23 and an exhaust pipe 24 arranged laterally of a tube 21 down which the sliver passes from the calender rollers 10. When a can is full, a stream of compressed air is blown through the nozzle 23 to sever the sliver and sliver still being delivered passes down the exhaust pipe 24. Upon an empty can being placed beneath the coiler, the jet from the nozzle 23 is cut off and air flows down a pipe 25 to re-introduce the sliver to the coiler tube. A system of relays opens and closes magnetically operated valves at appropriate times.

Abstract: 393,616. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and WILSON, W. P., 42, Vicarage Road, Chelmsford, Essex. Dec. 7, 1931, No. 33905. Drawings to Specification. [Class 40 (iii).] In a variable impedance network having invariable characteristic impedance the number of variable elements is reduced by the use of bridging arms. Thus an unbalanced T-section having three variable arms is equivalent to a bridged T-section having the shunt arm and bridging arm variable and the two series arms fixed. A balanced T-section or H-section, 'having five variable arms, is equivalent to a bridged H-section having the shunt arm and two bridging arms variable while the four series arms are fixed. Quantitative relations between the arms are given in the Specification for symmetrical networks. The bridge and shunt elements are inverse to one another.

Title: Method and device for making metal band connections
IPC: B65B13/34
Filed: 1937-12-09
Abstract: 506,676. Sealing. PRAEMASSING, A. Dec. 9, 1937, No. 34064. [Class 146 (ii)] In a machine for sealing the overlapping ends of metal bands by feeding in a strip of material, wrapping it round the overlapped ends, and deforming it, the deformation is effected by supplementary tools against the reaction of the forming tools. The supplementary tools move in the opposite direction to, and their movement is controlled by, the forming-tools. The band is drawn from a roll, and the overlapped ends are inserted in a slot 51 and tensioned by a known device 3 operated by handles 4, 5. The ends of the strap are aligned by a strengthening- web on the machine frame and the edge 48 of a stop 47 pivoted to the casing 12 and adapted to be held in position in the slot against the action of a spring by a spring-pressed pin 54 adapted to enter an aperture in the casing. A strip 62 for forming the sheath is fed into a transverse slot and is correctly positioned by a part 58 on the stop 47, a plate 69 being adjusted at a distance from the stop equal to double the width plus four times the thickness of the band. The handle 40 is then rotated in a clockwise direction to cause aneccentric 38<1> to depress a slide 14 in the casing 12 against the action of springs 41, 42 which, at the lower ends, are connected to pins 45, 46 on tools 15, 16 pivoted to the slide. Depression of the slide causes the release of the stop 47 through the action of a tapered recess in the slide on a plunger slidable in the aperture engaged by the pin 54. The strip 62 is severed by a cutting- edge on the tool 15 co-operating with the plate 69, and further depression of the slide causes the ends of the severed strip to be bent down - wardly by the tools 15, 16. The overlapped ends of the band and the strip are gripped by spring-pressed members 72, 73, Fig. 6, in the slide 14 in conjunction with the sides of the recess in the base-plate, so that there is'no tendency for the parts to bend except under the influence of the tools 15, 16, pivoted levers 29, 30 also assist in gripping the band. At this point, a concentric part 38<11> on the lever 40 engages the slide to maintain it depressed, and wedge-shaped projections 43, 44 enter between the upper ends of the tools 15; 16, thus forcing the lower ends together in an upward direction to bend the ends of the strip 62 under the ends of the band. The levers 29, 30, which may be formed with cutting-edges, are then forced inwardly and downwardly by the tools 15, 16 to deform a portion on each side of the seal. On return of the handle 40, the springs 41, 42 act to restore the tools 15, 16 to original position relatively to the slide, this effecting the rocking of the levers 29,-30, and finally raise the slide. Specifications 471,454 and 472,483 are referred to.

Filed: 1946-11-19
Abstract: 619,091. Burners. ELLIS, L. S. E. (Robertshaw Thermostat Co.). Nov. 19, 1946, No. 34268. [Classes 75 (i) and 75 (iii)] In an electric safety control system for fuel burner apparatus comprising a thermal resistor located to be heated by the burner flame and connected in parallel circuit with electrically operable fuel control means adapted in accordance with the value of the current supplied to it to either prevent or permit the supply of fuel to a burner, and current responsive means adapted upon occurrence of an open circuit in said thermal resistor to move the fuel control means to fuel supply preventing position, a switching means controlled by a timing element is provided for preventing such operation of said current responsive means for a predetermined period following energisation of said thermal resistor, during which period the latter becomes heated, and for permitting such operation at the expiration of said period. The flow of fuel through a supply pine 12 to a fuel burner 10 is controlled by a manually or thermostatically operated valve 14 and an electromagnetically operated valve 16, and the operation of opening the valve 14 closes an electric switch incorporated therein to supply current from the secondary coil of a transformer 24 to a parallel network connected between the points A, B, and comprising a resistor 38 in parallel with the operating coil 44 of the valve 16, a resistor 46, and a cut-out 48. The resistance of the resistor 38 is increased by heat from the flame of a pilot burner 18, and if this flame should become extinguished the cooling of the resistor 38 will cause a decrease in the current flowing in the parallel circuit sufficient to render the coil 44 incapable of maintaining the valve 16 open, and the supply of fuel to the burner 10 is terminated. Should the resistor 38 become open circuited the cut out 48 is operated to open the parallel circuit also. For a short period after the initial opening of the valve 14, a switch 60 controlled by a relay 30 provides a circuit in parallel with the cut out 48 through an igniter coil 66 for igniting the pilot burner 18, said parallel circuit rendering the cut out 48 inoperative during said period. For a shorter period the valve 16 is maintained closed by a short circuit of the operating coil 44 through a switch 86 also controlled by the relay 30. Specifications 576,893 and 589,963 are referred to. Reference has been directed by the Comptroller to Specifications 602,287 and 610,145.

Title: Improvements in or relating to the protection of direct current electrical feeders
IPC: H02H7/26
Filed: 1946-11-19
Abstract: 619,015. Protective cut-out systems. LONDON PASSENGER TRANSPORT BOARD, and READMAN, A. Nov. 19, 1946, No. 34299. [Class 38 (v)] A protective system for direct-current feeders utilizes an alternating-current protective circuit. Four iron-cored transformers T1 ... T4 are arranged in pairs with their primary windings forming part of the circuit 10, 11 to be protected and their secondary windings S1 ... S4 connected in bridge formation, the secondary windings S2, S4 being wound in opposite sense to S1, S3. An A.C. voltage is applied across two points 12, 13 of the bridge and a trip relay R is connected across the other two points 14, 15. Under normal conditions, the bridge is balanced as points 14, 15 have the same potential. Should a fault occur, the resulting potential difference at points 14, 15 will cause the operation of the relay R. This protective circuit may be used to protect two parallel D.C. lines of the same polarity (Fig. 2, not shown), or to protect a single D.C. line (Fig. 3, not shown). In the latter case the pairs of transformers are arranged at opposite ends of the line and connected by a 3-core pilot cable. The transformers may have single turn primary windings and additional multi-turn windings for test purposes. The Specification sets out the theory of the operation of the system.

Title: Hydrogen generating device
IPC: B01D71/02
Filed: 1976-08-18
Abstract: 1489054 Separating hydrogen and oxygen COMPAGNIE GENERALE D'ELECTRICITE SA 18 Aug 1976 [27 Aug 1975] 34358/76 Heading BIL [Also in Division C1] Means for the dissociation of water and separation of the resulting hydrogen and oxygen comprises a furnace in the form of a sleeve 1 heated by solar energy concentrated by a mirror or wave guide to a point 4. Water which may be pre-heated by circulation through cooling devices 15 and 19 enters at 28, and in passing through tube 26 and heat exchanger 25 is vaporised to steam, which is superheated by passage through heat exchanger 24 to about 800C when it reaches the inlet 9 of tube 5. As the steam passes along tube 10 inside tube 5 its temperature is further raised to about 2200C and it is decomposed into hydrogen and oxygen. Oxygen ions are diffused through membrane 7, electrons returning in the opposite direction, and vacuum pump 14 is used to reduce the pressure of oxygen adjacent the membrane and so increase the rate of diffusion. Oxygen so obtained is stored under pressure in tank 16. Removal of the oxygen in this way shifts the equilibrium point of the reaction and so enhances the dissociation of the steam, the difference in oxygen pressure on either side of the membrane being sufficiently great for practically pure hydrogen to remain at the outlet 11 of tube 5. This hydrogen is stored under pressure in tank 21, traces of undecomposed water being condensed in condencer 30. The membrane is constituted by a metallic oxide doped to obtain both the passage of oxygen ions through the membrane and the return conduction of electrons therethrough. Zirconia may be used, doped with traces of yttrium oxide and calcium oxide to facilitate ionic conduction and with iron oxide Fe 3 O 4 , uranium oxide or cerium oxide to facilitate electronic conduction.

Title: Colour television receiver
IPC: H01J31/20
Filed: 1955-12-02
Abstract: 788,576. Colour television. STANDARD TELEPHONES & CABLES, Ltd Dec. 2, 1955 [Dec. 13, 1954], No. 34567/55. Drawings to Specification. Class 40 (3). [Also in Group XL (a)] Relates to a receiving arrangement utilizing a luminance signal and a chrominance signal, and employing a dot-screen shadow-mask type of cathode-ray tube (see Group XL (a)) in which the beam is predeflected by two co-ordinate signals derived from the chrominance signal so that it passes through the mask apertures in such direction as to strike the phosphor dots on areas necessary to produce the colour defined by the chrominance signal. A tube of this type requires a beam intensity control signal in the form of a brightness signal, i.e. a signal formed of equal fraction of the component colour signals, red, green and blue, and in accordance with the invention a signal of this character is produced by combining appropriate proportions of one or both of the colour co-ordinate signals with the luminance signal. The invention is described more particularly with reference to signals according to the American N.T.S.C. standards as set out in Proc. I.R.E., January, 1954, and in one arrangement a brightness signal Br=k(R+B+G) is obtained from the luminance signal Y=.59G+.30R+.11B by combining it with proportions of the I and Q colour co-ordinate signals according to the equation Br=k(Y+.57Q-.15I). With the N.T.S.C. signals, the application of the I and Q signals to orthogonal deflecting means to produce the predeflection of the electron beam ideally requires a phosphor dot pattern in which the three phosphors, red, green and blue, associated with each mask aperture are not disposed symmetrically 120 degrees apart, but at angles of 137 degrees, 107 degrees and 116 degrees. Reference is made both to the use of a phosphor screen arranged in this manner, and a conventional symmetrical screen operated with colour-co-ordinate signals other than I and Q. These signals are derived from the chrominance sub-carrier signal at phase angles of 13.4 degrees and 119.7 degrees with reference to the synchronizing burst instead of 33 degrees and 123 degrees for the I and Q signals. The proportions of these signals to be combined with the luminance signal to produce a brightness signal are different from those quoted above. Reference is also made to the use of co-ordinate signals derived from the sub-carrier at angles such that they correspond to Q-.27I and .82I - 0.3Q. In this case the desired brightness signal may be produced with the aid of only the first of the co-ordinate signals, since Br=Y+.57 (Q-.27I). The predeflection applied to the electron beam may be increased in extent such that the beam impinges groups of phosphor dots other than those immediately related to an aperture. Specification 779,564, [Group XL (a)], is referred to.
