Abstract: 1,203,678. Glass manufacture. J. M. Y. LE CLERC DE BUSSY. 24 June, 1968 [7 July, 1967], No. 29991/68. Heading ClM. A device for producing small articles, e.g. pellets, from a continuous stream of glass OE comprises an endless conveyer 6 on which are mounted a series of open moulds 1, means for driving the conveyer 6 to bring each mould successively into vertical alignment with the orifice discharging the glass stream OE and a series of triangular shaped glass-stream separating bars 11 extending transversely relative to the direction of motion of the conveyer, the apex of each bar 11 lying in the plane of separation of, and above the rims of two adjacent moulds when the moulds are directed towards the pouring orifice. The apex of each bore 11 is preferably rounded. The bars may be made of steel or graphite. Glass in a stream at a temperature in the range 1500-1600 C. is fed successively to the mould 6 adjacent the upstream end of the upper reach of the conveyer. The correct quantity of glass fed to each mould is a function of the speed of the conveyer the stream being severed and diverted by the bar 11. The cooled pellets are discharged by the inversion of the mould as a transfer to the lower reach of the conveyer. Before being reused the moulds are cooled and, if desired, lubricated by spraying. Each mould, which comprises a cylindrical moulding cavity 2 and divergent walls 3, is screwed to a plate 4 mounted on a chain forming the conveyer. If desired, the moulds can be used to form a pre-form which is transferred whilst still plastic to a conventional press-moulding machine.

Oct. 26, 1932, No. 30013. Convention date, Oct. 26, 1931. [Class 38 (ii).] The potential drop across an inductance, used as a smoothing choke in the D.C. supply circuit to an amplifier and as the energizing winding of a loud-speaker, is used to bias the grids of the valves. The anodes of the valves 6 in a push-pull amplifier are supplied from an A.C. supply through a rectifier 1 and smoothing circuit 3 employing condensers 4 and an inductance 5 which is used as the energizing winding of a loud-speaker 2. One end of the winding 5 connects to the valve cathodes and the other end connects through a resistance 8 to the centre tap of the secondary winding 9 of an input transformer 10 supplying the grids so that the grids are biased by the potential drop in the winding 5. The supply is smoothed by means of a condenser 12. In a modification .a potential divider is connected across the winding 5 and the resistance 8 is connected to an intermediate point. Reference is made to Specifications 248,731 and 294,250, [both in Class 40 (v), Wireless signalling &c.], wherein the two features of the present application are described separately.

Abstract: 652,842. Cigarette making machines. INDUSTRIAL MACHINERY CO., Ltd., and HORGAN, G. D. Nov. 19, 1948, No. 30163. [Class 130] In a continuous-rod machine, comprising a knife 19 having an eccentric arcuate cutting-edge and mounted for orbital rotation in a carrier 12 rotatable about an axis inclined to the axis of the cigarette rod, the carrier is rotated about the axis of the driving-gear of a gear train by which the knife is driven, the driving-gear being rotated in a direction opposite to that of the carrier whereby an increment of rotation is added to the knife to that imparted by the gear train. The knife and the carrier are respectively rotated by bevel gears 5, 6 from a bevel gear 7 on the driving shaft 26. The ledger plate 31 for the cigarette rod is mounted on radius rods 23 and reciprocated by a crank pin 27 mounted on a plate 28 adjustably secured to a disc on a shaft driven from the shaft 26. Owing to the high speed of the cut the normal inclination of the cut-off to the cigarette-rod axis may be reduced or even eliminated.

Abstract: 602,942. Driving magnetos. BRITISH THOMSON-HOUSTON CO., Ltd., and GRIFFITHS, L. Nov. 12, 1945, No. 30204. [Class 35] An impulse starter for a magneto has a restraining pawl 6 pivoted at 5 on the magneto end plate 1 to engage one or more notches 3a in a boss 3 secured to the magneto shaft and driven by a spring 9 from a driving member 8 which is also provided with a cam surface 8a for periodically disengaging the pawl. The relative displacement is limited by a tongue 8d on the driving member engaging a slot 3b in the boss 3 and the pawl has an extension past the tooth 6a for increasing its inertia and engaging a limit stop 7. The cam acts on the pawl at a bent-over lip 6b.

Abstract: 464,991. Variable - pitch propellers. ALGARSSON, G. Nov. 1, 1935, Nos. 30268 /35 and 21843/36. [Class 114] In automatically variable pitch propellers of the kind in which the blade pitch is adjusted and controlled by centrifugal means arrangements are made for varying the effective mass of centrifugal means in accordance with the corresponding pitch change. The Figure shows diagrammatically the mechanism employed. A series of weights 44 are slidably mounted on the rods 45 arranged in the interior of the propeller blades 38 and terminating at the end in the fixed weights 46 and at the propeller root in the fork 48 with the off-set prongs 49, 50. The prongs 48, 49 gear with spring ears 24, 25 journalled on a propeller shaft sleeve and integral with bevel gears 26, 27 which in turn gear with bevel gears 30 rigid with the blades 38. The centrifugal action of the rods and associated weights effects the pitch adjustment. As this force increases the masses including the yokes 48 move outwards. The movements of the weights relative to the blades 44 are however successively arrested starting from the innermost until at top speed only the weight of the rod and the terminal weight 46 are effective.

Abstract: 898,877. Bearings; lubricating systems. FORD MOTOR CO. Ltd. (Ford Motor Co.). Sept. 7, 1959, No. 30434/59. Classes 12 (1) and 12(3). A bearing comprises a journal 11 rotatable in a sleeve 16, means for ensuring the flow of lubricant from a reservoir 17 to the surfaces of the journal and sleeve, and means 24 mounted on the journal for returning the lubricant to the reservoir. The sleeve 16 of sintered bronze is a press-fit in a housing 13 secured by bolts 15 to a dynamo-electric machine. The sleeve is retained by a cap 21. Reservoirs 17 are formed in the sleeve and the end of the housing and are filled with a cellulose material impregnated with the same lubricant as is the sleeve. A disc 24 which is a press-fit on the journal 11 rotates with the journal to cause lubricant flowing along the bearing surfaces to be flung outwardly and thus returned to the reservoirs. The reservoirs 17 may be formed in the outer surface of the sleeve or in corrugations formed in the housing 13. In a further modification, the sleeve 16, Fig. 6, is of wrought material and contains reservoirs communicating with the bearing surfaces by passages 28, the passages and reservoirs being limited to the portion of the sleeve carrying the lesser working pressures. This bearing may also be modified to have the reservoirs in the surface of the sleeve or in housing corrugations 13, Fig. 9.

A rotary compressor (or expansion motor) of the type having an inner rotor co-operatnig with an outer rotor has a two-port control valve concentric with the inner rotor whereby the points of discharge ending and suction beginning are adjusted together by rotating one of the control parts, to vary the volumetric capacity. In Fig. 1 the inner rotor 2 of a compressor has inlet and outlet ports 3, 4, 5 which periodically communicate with an inlet passage 9 and an outlet passage 8 in the control valve which comprises a fixed partcylindrical shell 6 and a rotatable part 7. By rotating the part 7 slightly clockwise the port 4 remains in communication with the passage 8 while the working space K2 starts to increase in volume so that a larger volume of air trapped in this space when the port 4 closes is carried back to the inlet passage 9. The port 4 communicates with the passage 9 later now as the central surface 13 has moved to the left, but the part 7 and the port 4 are so dimensioned that the trapped air in the space K2 will have expanded to inlet pressure when the port 4 communicates with the passage 9. The part 6 may be made exchangeable or adjustable to determine the discharge pressure.
