Patent GB-1547655-A (GB)
Title: Closure valves of transportable containers for gas under pressure
IPC: A62B9/02
Filed: 1976-11-18
Abstract: The cylinder valve for a pressurised-gas cylinder has a closing pin (4) which can be moved axially by means of a hand wheel (14) and consists of a shank (6) and a closing element (7). The closing pin can be pressed against the valve seat (9) by turning the hand wheel. The shank (6) is surrounded by a prestressed spring (16) which likewise presses the closing pin against the valve seat (9). If the valve is opened by means of the hand wheel, pressurised gas flows out until the force of the spring on the closing pin is greater than the pressure exerted on the closing pin by the internal pressure in the cylinder. A small residual supply of pressurised gas thus remains in the cylinder. Since the spring (16) now keeps the valve permanently closed until the cylinder is refilled, no moisture or dirt can penetrate into the cylinder. <IMAGE>

IPC: H01P1/18
Filed: 1967-10-30
Abstract: 1,142,455. Variable phase - shifters. TELEFUNKEN PATENTVERWERTUNGS G.m b.H. 30 Oct., 1967 [16 Nov., 1966], No. 49154/67. Heading H1W. A variable phase-shifter comprises a dielectric plate 2 extending parallel to the axis of a waveguide 1 and rigidly attached to a carrier block 6 which is transversely movable between adjustable limit stops. The carrier slides on a post 7 between positions determined by bolt 11 and screws 9, 10. It is actuated by a lever pivoted at 15 which comprises a U-shaped member 14 having between the ends of its arms a pin 16 which engages a slot in the carrier. The base of the U-shaped member 14 carries two leaf springs (only one, 18, shown) which extend in two parallel planes arranged symmetrically on either side of the pivot 15. The springs are arranged in positions spaced in the axial direction of the pivot and are respectively engaged by bilobal cams (only one, 19, shown) arranged on a common shaft 13. The lobes of the cams are arranged at right angles to each other in such a manner that a 90 degrees rotation of the shaft 13 causes positive actuation of the lever in one direction or the other. The 90 degrees increments of rotation are transmitted from a pawl-and-ratchet mechanism (Figs. 4 and 5, not shown) consisting of a four toothed ratchet keyed to the shaft 13 and a spring pawl carried by a drum freely rotatable on the same shaft. The drum may be rotated back and forth through a 90 degrees arc by means of a solenoid and a return spring connected to the drum by e.g. chains. A positive mechanical stop is provided by a square cam keyed to the shaft 13 and a plate spring-biased towards the cam such that it successively engages the four sides of the cam. The specification also refers to direct actuation of the carrier 6 or the lever 14 by a pair of electromagnetic devices or one such device and a spring.

Title: Telegraph receiving apparatus
Inventor: HOLLAND JOHN DOUGLAS
IPC: H04L1/06
Filed: 1965-11-19
Abstract: 1,123,416. Radio receiving systems; telegraphy. STANDARD TELEPHONES & CABLES Ltd. 19 Nov., 1965, No. 49261/65. Headings H4L and H4P. In an alternating-current telegraph receiver including two separate signal paths, the said paths are coupled to a common impedance by a hybrid circuit arrangement so arranged that substantially no power is transferred from either path to the other. As described, the output A of a first receiving channel of a radio diversity system is connected through a band pass filter 1 to a hybrid transformer 4, by which it is divided to feed a mixer 8 in a "mark" channel 33 and a similar mixer 9 in a "space" channel 35. Similarly, the output B of a second receiving channel is divided by a hybrid transformer 11 to feed a mixer 15 in a "mark" channel 34 and a similar mixer 16 in a "space" channel 36. A common local oscillator 17 is coupled by a hybrid transformer 19 to the mixers 8, 15 and a common local oscillator 18 is coupled by a hybrid transformer 24 to the mixers 9, 16. In the hybrid transformer 4, the value of the balancing resistor 7 is so chosen in relation to the input impedance associated with the primary winding 3 and the turns ratio between the secondary 5, 6 and the primary, that there is substantially no cross-coupling between the mixers 8 and 9. Similar considerations are applied to the other hybrid transformers 11, 19, 24. With a frequency shift keying system, the input carrier frequency may be 100 kc/s, with Œ0À1 kc/s shift, the oscillators 17, 18 being set, respectively, at 94À9 kc/s and 95À1 kc/s, so that the "mark" and "space" outputs are all at 5 kc/s. The arrangement may be extended for use in a frequency-shift diplex system, where four frequencies deviated from a carrier are used, or it may be adapted for on-off keying, when the oscillator 18 would be disabled. With a non-diversity system only one hybrid transformer, 4 or 11 would be used.

As shown the wheel 24 drives two brushes 23 via spindles 35, bevel gears 36 and gear sleeves 38 surrounding and rotationally fast with the brush spindles 41. The upper end of each sleeve 38 engages in a conically widening recess 46 acting as an upper bearing seating portion, the outer end of each sleeve engaging in a hole 51 elongated in the front-back direction of the sweeper to allow tilting of the spindle 41. The hole 51 is formed in a removable cover 26. Slight vertical movement of each brush 23 is possible if the spindle 41 is made longer than the sleeve 38. Tilting of the brush 23 is brought about by engagement of its bulbous undersurface with the floor. Specification No. 1,362,323 is referred to.

Title: Method of Coating Mineral Fibers with Binding or Sizing Materials

Filed: 1966-11-08
Abstract: 1,169,034. Coating mineral fibres. CELOTEX CORP. 8 Nov., 1966, No. 50066/66. Headings D1P and D1R. [Also in Division C1] Mineral fibres are coated with a liquid binder, e.g. phenol formaldehyde resin, or sizing material by forming individual mineral fibres from molten slag, atomizing the binder or sizing material to form fine droplets such that more than 90% of the droplets are smaller than 0.11 inches in diameter and not less than 0.01 inches in diameter and coating the fibres with the atomized binder or sizing material. A resin bonded mineral fibre board may be produced by forming an interfelted blanket of the coated fibres and curing the binder under heat and pressure to rigidity the blanket. The binder may be applied to the fibres immediately after they are formed or at any point along their path within two feet after they are formed. In Fig. 1 slag 11 melted at temperatures of about 2600F is applied over a trough 14 to a rotor 10 the upper face 17 of which is cut away to leave a cup-shaped depression 18 for receiving molten slag which is centrifugally thrown over lip 20 when the rotor is rotated by shaft 22. Steam supplied through pipe 36 is blown from the holes drilled round the underside of steam ring 35 under pressure past the lip 20 and attenuates the molten slag centrifugally thrown off the lip into thin streams of molten slag to form fibres which are collected on conveyor 40. Binder is fed from supply source 31 by pump 30 through tube 25 to nozzle 28, a rotary joint 32 being connected between shaft 22 and the upper section of tube 25 so that the lower end of the tube 25 may rotate without rotation of its upper end. The nozzle may comprise a threaded base portion and a helical shaped vane extending axially from the threaded base portion and spiralling inwardly its inner wall having an inward axial taper to form a bore in a conical or bullet shape so that the crosssection of the bore is reduced in the direction of flow through the nozzle. The spray of binder may be in the form of a sheet substantially planar and perpendicular to the lower end of the tube 25 or may form a cone whose inside angle is 120 or 270. Alternatively a non-rotating nozzle may be used. In a further alternative binder is supplied through an outside spray ring 80 supplied through tube 81.

[Also in Division E2] A log-periodic aerial array comprises two support booms, which also act as feeders, from which elements of parallel dipoles extend transversely. Said elements of each dipole are mounted on the booms reversely with respect to those of the adjacent dipoles, to obtain relative cross-phasing (Fig. 1, not shown).
