Title: Improvements in or relating to apparatus for mixing and delivering measured quantities of liquids in variable ratios
IPC: B67D7/74
Filed: 1958-08-11
Abstract: 849,428. Mixing liquids. PILLIN Ltd., J. B., and EARLY, K. C. April 29, 1959 [Aug. 11, 1958], No. 25750/58. Class 86 [Also in Group XXVIII] In a dispenser-meter apparatus for delivering a mixture of petrol and oil in predetermined proportions to a mixing chamber and thence to a delivery point of the kind in which a variable volume of oil may be added to substantially constant successive charges of petrol, a device adjusts the ratio of the liquids to compensate for the differing ratio of any mixture left in the apparatus from a previous delivery. As shown diagrammetrically in Fig. 1, oil is pumped from a tank 85 by a pump 84 and petrol by a linked pump 80 to a mixing chamber 83 and thence via a filter 91 meter 92 and valve 93 to a delivery box 94. The compensator 91 is connected by the branch pipe 90 to the oil supply pipe 87. In the arrangement of Fig. 4, the compensator consists of a cylinder 59 having two pistons 58, 60 separated by an annular space 101. The piston 60 has a closed tubular extension 102 slidably received in the piston 58 and receiving the compression spring 61. The annular space 101 is in connection through the branch pipe 64 with the oil delivery pipe 48 of the oil pump 43, the delivery of which may be varied by rotating its cylinder 42, (Fig. 2, not shown see Group XXVIII) by means of the arm 44 and shaft 45. An indicating drum 51 showing the selected ratio of petrol to oil and a cam track 57 which abuts on the head of the piston 58 are mounted on the shaft 45. If the arm 44 is rotated to set the apparatus to deliver a mixture having a lower proportion of oil than previously, the cam tracK 57 rotates in such a way as to withdraw from contact with the piston 58. On operation of the apparatus part of the oil delivered by the pump will be diverted from the supply to the mixing chamber and enter the space 101, forcing the pistons 58, 60 apart until the piston 58 is again in contact with the cam track 57. Conversely if the mixture to be delivered is to have a higher proportion of oil than previously the cam track 57 will assume a position in which it tends to force the piston 58 towards the piston 60. The oil trapped in 101 being incompressible, the pistons 58, 60 will move as an assembly against the spring 61. When delivery takes place, the pressure in 101 will be released and the spring 61 will move the piston 60 towards piston 58 discharging part of the oil in 101 into the mixing chamber in addition to that delivered by the pump. Specification 849,429 is referred to.

Carbon filaments are produced by feeding organic filamentary material, which has been treated at 200-300‹ C. in air, air enriched with oxygen, oxidizing atmosphere or nitrogen, into a receptacle, e.g. a carbon boat, in layers of coils and causing the loaded receptacle to travel through a heating zone containing an inert atmosphere and heated to not less than 1000‹ C. to carbonize the organic filamentary material. The heating zone is preferably a large aperture tunnel furnace through which successive open-ended receptacles which are loaded continuously from one boat to another are pushed. The temperature is preferably graded through the heating zone so that the inlet end is cooler than the outlet end. Mechanical means for moving the receptacles may be installed at the cool end of the heating zone. The organic filamentary material may comprise filaments consisting of cellulosic, polyamide or polyester filaments preferably filaments of polyacrylonitrile. The filaments may be further graphitized by heating in an inert atmosphere to 2000‹ C. preferably greater than 2500‹ C.

IPC: H03D3/00
Filed: 1961-07-20
Abstract: 912,317. Frequency modulation. COMPAGNIE FRANCAISE THOMSON-HOUSTON. July 20, 1961 [July 20, 1960], No. 26379/60. Class 40 (5). In a frequency-modulated signal receiver, the frequency excursion of the received signals is reduced, and before amplitude limitation the carrier to sideband amplitude ratio of the frequency compressed signal is increased; the signal being then amplitude limited and detected to extract the transmitted information as an audio signal. In Fig. 1, signals from an aerial are amplified and applied to a mixer receiving signals from oscillator 4 which is in turn variable reactance frequency modulated from the audio output to produce an intermediate frequency having a lesser frequency excursion than the aerial signal. The I.F. energizes an amplifier (which may comprises a frequency divider 8) transformer coupled to a network 9 comprising a non- selective resistive attenuator 10, 11, 12, of which 10, 12 are shunted by a carrier frequency piezo-electric crystal 12 whose capacitance is neutralized by variable capacitance 16 or a shunting inductance (Fig. la, not shown) which by resonance increases the carrier amplitude relatively to the sideband amplitude (Fig. 2). The resultant signal is applied to a known limiter and detector to produce an audio output which is applied over connection 6 to modulate oscillator 4. A network 22 may be inserted to correct for over-amplification of the lower sideband frequencies arising from the broadening of the base of the transmission characteristic of network 9.

Abstract: 668,259. Glass. BRITISH THOMSONHOUSTON CO., Ltd. Oct. 30, 1950 [Nov. 3, 1949], No, 26400/50. Class 56. U-shaped glass tubes, e.g. for fluorescent and germicidal discharge lamps, having closely spaced parallel straight portions and a curved joining portion, the wall thickness being substantially uniform throughout, are formed by holding a pair of open-ended straight tubes 1, 2 in side-by-side and closely spaced relationship ; heating two adjoining ends to a plastic condition and pressing the plastic wall portions together to join them; cutting through the walls at the plastic juncture and longitudinally of the tube, the cut being shorter than the length of the juncture to leave a part of the juncture unsevered whilst the cutting operation unites the severed surfaces 8, Fig. 3, into side walls common to both tubes ; shaping the walls 8 to conform with the diameters of the tubes 1, 2 and then closing the bottom of the space joining the tubes 1, 2. The tubes are heated by ribbon burners 5, 6 and the juncture and cut is effected by a pair of shears 7. On continued heating by the burners 5, 6, the walls 8 separate and conform approximately with the tube diameter. The lower part of the space between the walls 8 is closed by arranging the burners to play along a horizontal line 9, Fig. 5, and then severing the plastic glass by the shears 7 along this line. Alternatively the cullet could be melted off by the burners. The curved part of the U-tube is finally shaped by blowing in a split mould. Any number of straight parallel tubes may be joined at their ends in pairs to form a composite tube.

[Also in Group XXVIII] An expansion joint comprises a corrugated bellows A provided with hollow reinforcing rings C fitting in the corrugations, the rings being ovoidal in cross-section and formed from a sheet metal member 16 bent into shape and welded to a surrounding band 28. The bellows A is connected to end flanges B having projecting ribs 13 and a reinforcing ring 12 and the rings C are operatively interconnected by links secured to bosses 23. To form the rings C a rectangular metal sheet 16 is bent into open U- shape, Fig. 5, and its outer ends are then forced together, Fig. 7, and the channel-shaped member is bent into annular shape. The band 28 is welded to the outer edges 20, apertured lugs 29, Fig. 4, are welded to the band at diametrically opposite points and the ring divided through the centres of the lugs 29 to provide two semicircular sections 27 which can be fitted around the bellows and bolted together by bolts 25 passing through the lugs 29. The end rings D need not be divided into semi-circular sections. In a modified method, Fig. 12, the sheet 16, after forming into the closed channel shape of Fig. 7, is bent into a helical spiral 31 which is cut longitudinally along one side to obtain one split annulus for each turn of the spiral. The laterally displaced ends of each annulus are forced into register and the band 28 welded.in position as previously.
