Title: Improvements in or relating to methods of and apparatus for feeding molten glass
IPC: C03B7/08
Filed: 1921-06-23
Abstract: 190,737. Lott, C. R. June 23, 1921. Delivering molten metal.-A feeding-device for delivering gathers of glass comprises a furnace having a valve-controlled passageway leading to a closed cup or container provided with a discharge orifice, and means for regulating the flow of glass through the orifice by subjecting the container alternately to suction and compression. The container consists of a closed funnel-shaped cup 236 connected with the furnace 230 by a passageway 231 which can be closed or opened by a valve 232. This valve is connected by racks 233, 322 and a pinion 234 with an elbow lever 320 which is rocked by an arm 57 of the forming machine. The lever 320 also operates a valve 300, which is connected with the container by a conduit 240 and with sources of compressed air and vacuum. The arm 57 also operates shears 276, which are .moved to and from the outlet 239 of the container and sever the stream 245 of glass as it issues from the outlet. In operation, the valve 232 is closed to cut off the supply of glass to the container, and immediately the valve closes, compressed air is admitted to the container to force the glass out into the mould 23 of the forming machine. As soon as a charge is supplied, the valve 300 is operated to connect the container with the vacuum tank. The suction causes the stream of glass issuing from the container to form a neck where it is cut by the shears. At the same time, the valve 232 has been raised so that the suction causes glass to flow from the furnace into the container. The container may be enclosed by a casing 243 which is heated by gas burners 244. In a modification, the container is connected to the furnace by a siphon the inner end of which is alternately closed and opened by a plug.

Both screws 12, 21 may be rotated simultaneously through bevel and worm gearing 25 ... 32, the worm-wheel 29 also being connected to the screw 21 through a coupling 33, whereby the screws may be adjusted individually. Specification 389,762 is referred to.
Patent GB-786668-A (GB)
Title: Production of polyalkyl benzenes
IPC: C07C4/24
Filed: 1955-06-15
Abstract: Alkyl benzenes having at least 3 alkyl groups are produced by condensing an aromatic hydrocarbon feed having at least 2 alkyl groups per molecule and having at least one unsubstituted nuclear hydrogen atom per molecule with formaldehyde to form a di-arylmethane, subjecting the diarylmethane to hydrogenolysis (i.e. the cleavage of a carbon to carbon bond accompanied by the addition of hydrogen) to produce alkyl benzenes and separating the product of hydrogenolysis to recover an alkyl benzene having one more alkyl group substituted on the nucleus than the aromatic hydrocarbon feed. The condensation is preferably catalysed by sulphuric acid optionally in the presence of methanol, ethanol, or glacial acetic acid. Alternatively, phosphoric acid trichloracetic acid, ferric chloride, methane sulphonic acid or hydrofluoric acid may be used, condensation being effected at 30-300 DEG  F.  The hydrogenolysis is preferably conducted at 650-900 DEG  F. at a pressure ranging from atmospheric to 250 p.s.i.g. and may be catalysed by metals, oxides and sulphides of Group VI (b) VII (b) and VIII of the Periodic Table, molybdenum oxide on alumina being especially suitable.  In examples, the process is directed particularly to the production of nearly pure pseudocumene by condensing any one of the xylene isomers or a mixture thereof with formaldehyde to produce a di-xylyl methane which is reacted with hydrogen to produce 1 molecule of xylene and 1 molecule of over 90 per cent 1,2,4-trimethylbenzene.  Durene may be produced by an extension of the process.

Title: Improvements in numerical printing devices
IPC: B41K3/10
Filed: 1936-06-22
Abstract: 477,154. Number-printing apparatus. BRILL, W. G. June 22, 1936, No. 17282. [Class 100 (ii)] In a number-printing apparatus for a printing-machine of the kind having a series of rotatable numbering-wheels, the step-bystep motion of the tens, hundreds, and other multiple-unit wheels is effected by interengageable teeth or other coupling elements thereon, each of the abovementioned wheels being connectible for its successive stepmovements to the lower multiple wheel adjacent (or, in the case of the tens wheel, to the units wheel), the units wheel being directly rotated by, and in synchronism with, the platen or equivalent of the printing-machine. A plunger 7 is depressed by a member of the printing-machine to oscillate a crank on a shaft 3, and a ratchet-device 16 fixed on the units wheel 18 moves the latter one-tenth of a revolution during each depression of the plunger. The wheels 18... 22 are rotatable on a fixed sleeve 2, and each wheel is provided with a cam disc 23 fixed on the sleeve 2, a cam slot 24 being formed in each disc. The numeral " 0 " of each wheel (in the case of a " backward-numbering " apparatus) is carried on a radially-slidable member 25 having a pin 26 engaging the cam slot 24. On the side of the member 25 a tooth 27 is provided, except in the case of the last wheel 22. Ten teeth 28 are fixed equiangularly around the inside face of each wheel 19 ... 22, these teeth corresponding with the type-numerals on the wheels. In operation, when the units wheel 18 has printed in succession the numerals " 9 to 1," the tooth 27 in the slidablo member 25 of the wheel 18 will have moved radially so that it practically engages the teeth 28. On the next step-movement of the wheel 18, the tooth 27 is raised into abutment with the tooth 28 which is uppermost on the tens wheel 19. The numeral '' 0 " on the units wheel is now uppermost, and after printing, it is moved one-tenth of a revolution, and carries with it the tens wheel 19. The member 25 has now descended so that the tooth 27 can no longer contact with any of the teeth 28 on the tens wheel. Thus the tens wheel 19 is moved one-tenth of a revolution for every complete revolution of the units wheel. Likewise, the tens wheel operates the hundreds wheel, and so on. The top of the plunger 7 is formed with type-letters " No. " Each wheel 19 ... 22 is formed with a decagonal rim 29 engaged by a spring-pressed detent-device. The member 25 of each wheel can be depressed below type level, the pin 26 thereon being received in a notch 34 in the cam slot 24.

Patent GB-819739-A (GB)
Title: Method and apparatus for assembling electric commutators
Inventor: CLARKE MICHAEL EDWARD
IPC: H01R43/06
Filed: 1956-06-06
Abstract: 819,739. Making commutators; jointing by forging. NAPIER & SON Ltd., D. June 6, 1957 [June 6, 1956], No. 17487/56. Classes 83 (2) and 83 (4). A method of assembling a commutator of the kind comprising a number of circumferentially spaced individual commutator bars mounted on a series of axially spaced supporting rings, or on a single ring, comprises assembling the bars and the rings or ring in position on a cylindrical locating member and spaced circumferentially apart by spacer members lying between the bars, and applying end pressure to the bars to cause the material of the bars to deform in a circumferential direction at least partly closing the gaps between the spacer members, deformation of the bars in a radial direction being restrained by one or more radial restraining members. Commutator bars 10 are assembled on rings 12, with slots 11 in the bars 10 accommodating beaded edges of the rings 12, positioned on a cylindrical mandrel 14. The bars 10 are located circumferentially by spacers 15 having longitudinal tapered blades 16 lying between adjacent bars 10 and extending inwards as far as the outer edges of the rings 12. The spacers 15 are located at one end in slots in a mandrel base extension 17 and at their other end in slots in a ram 18, being allowed a certain radial movement in said slots. The spacers 15 are backed by three arcuate shoes 20 to which pressure is applied by hydraulic rams 21 so that when the ram 18 compresses the bars 10 axially to close the slots 11 over the edges 13 of the rings 12, the bars 10 expand circumferentially to close the gaps between the spacers 16 and radial movement thereof is slight. The rings may alternatively be in slots in the outer edges of the commutator bars with the spacer members and backing shoes lying inside the rings and the central mandrel replaced by a hollow sleeve surrounding the bars. The rings may be completely buried in the bars after deformation thereof. Specifications 796,022 and 799,570 are referred to.

Abstract: 1427685 Making wire; drawing BERKENHOFF & DREBES GmbH 22 April 1974 [21 April 1973] 17588/74 Heading B3A and B3P Apparatus for making wire comprises a first drawing die 5 which cold draws wire 6 drawn through it by a first pulley 7, a second drawing die 3, a second drawing pulley 4 which draws the wire through the die 3, a contact wire annealing plant 2 which receives wire issuing from the pulley 7 and delivers it to the die 3, and driving means coupling the pulleys 7, 4 and arranged to rotate the pulley 4 at a greater speed than the pulley 7. In the annealing plant the wire is passed over rollers 10, 11, 12 and back over the roller 10, the rollers being at different potentials so that an electric current flows through the wire to heat it. The roller 10 is at zero potential and the wire is cooled between the rollers 12, 10. The wire then passes over a pulley 13 and through the die 3, which has a lubrication chamber 15. The pulleys 4, 7 are of the same diameter but mounted on shafts of different diameters so that a belt 19 rotates the pulley 4 at a greater speed than the pulley 7 to compensate for the reduction in diameter of the wire 6 after passing through the die 3. The drawn wire passes through an air nozzle 17. The wire may be brass, tombac or bronze for the wire of a Fourdrinier machine.

Patent GB-967344-A (GB)
Title: Coin-freed mechanism,particularly applicable to amusement apparatus
IPC: G07F17/32
Filed: 1962-02-06
Abstract: 967,344. Coin-freed apparatus. A. J. L. CROMPTON. March 27, 1963 [Feb. 6, 1962], No. 17624/62. Divided out of 967,343. Heading G4V. A coin-freed mechanism for an amusement machine comprises a pivoted coin shoot 12, Fig. 1 which is held in a first position by a spring 14 until moved to a second position by an electromagnet 16 where it can direct an inserted coin to rotate a spring-urged member 22 having a notch 27 in its periphery for receiving a spring-urged setting arm 28 which then pivots at 29 and operates one or more make-and-break contacts 36, a re-setting electromagnet 31 being arranged for pulling the arm away from the notch and thereby allowing the member to return to its original position. A striker pin 24 on the member 22 projects through a slotin in a director-plate 26. The mechanism may form one of a number of play-stations of the amusement machine described in Specification 967, 343. The shoot 12 is normally in the second position and a coin inserted into the shoot is directed to the right-hand side of a deflector plate 20 so that it can operate the striker pin 24 against the action of the spring 25 and cause operation of the contacts 36; further coins inserted at this time are deflected to the other side of the deflector and returned to the operator because operation of the contacts 36 has resulted in de-energization of the electromagnet 16. In a modification, the pin 24 is arranged to project directly into the coin shoot when the shoot is in its second position, the deflector plate in such a case being omitted. When the mechanism is used as a play-station in an amusement machine, the machine may be started by the insertion of a coin, a further pair of contacts 36 being provided for this purpose; these contacts operate a relay having contacts which start the machine. At the end of the machine cycle, the electromagnet 31 is momentarily energized to return the member 22 ready for the next game. The coins may be fed into a coin-tube 39 having a coin-dispensing mechanism at its lower end which comprises an electromagnet 42, Fig. 3 winch, when operated by the machine on the event of a "win", pivots a plate 40 across the lowermost coins so as to reject one or more coins into a pay-out receptacle. When the tube is full of coins, further coins which arrive slide over into a shoot 45 leading to a coin-box.

Abstract: 780,197. Cutting by spark discharge. CENTRE NATIONALE DE LA RECHERCHE SCIENTIFIQUE. June 16, 1954 [Dec. 21,1953], No. 17755/54. Class 83 (4). A pair of condensers are connected in the supply circuit so that at any time one of them is effectively connected in series between the current source and the spark gap to prevent arcing. The condensers are charged alternately and discharge simultaneously. A direct-current supply 10, Fig. 1, is connected through switches 13, 14, which may be mechanical or electronic, to charge the condensers 6 and 7 in turn. The condensers 6, 7 are connected in parallel with a condenser or delay network 3 and in series with the spark gap 1, 2. In a modification, Fig. 3, an alternating current source is connected through rectifiers 11, 12 to charge condensers 6, 7 in turn and an inductance 8 and rectifier 9 are connected in series with the spark gap. In another modification, Fig. 5, a condenser 3 charged by the alternating current source 10 acting through condensers 6, 7, discharges through a valve 15 and the primary of a transformer 17 when the valve 15 conducts in response to a pulsating voltage applied from a source 20 to the grid. The secondary of the transformer 17 is connected across the spark gap. Alternatively the valve 15 may be replaced by a thyratron connected in series with the primary of the transformer and the current source. The thyratron is caused to conduct by a pulsating voltage applied to its grid and is extinguished by an oscillatory circuit connected between the cathode and anode.

Filed: 1945-07-12
Abstract: 598,082. Lathes. TAREX SOC. ANON. July 12, 1945, No. 17793. Convention date, Aug. 21, 1944. [Class 83 (iii)] A tool turret, for an automatic lathe, mounted on an axis parallel to that of the lathe spindle and having tool-slides actuated consecutively and independently of one another is characterised in that, each tool-slide is secured to a separate auxiliary slide, each of which carries a movement transmitting device on its outer face adapted, at one position of rotation, to come into engagement with an actuating member for controlling the movements of the tool-slides. The rotatably mounted head 1 carries tool-slides 3 which are connected by rods 12 to auxiliary operating slides 4 carried at the rear of the locking disc 10. The slides 4 are provided with angularly adjustable camplates 6 with slots 31 on the upper faces adapted to be engaged at the working station by a roller 30 carried on an arm integral with a screwed sleeve 29. A lead screw 28, driven by automatically reversible gearing, moves the sleeve and thus the tool-slide within the limits of stops 34, 35, which are engaged by a lug 33 on the sleeve, the former stop effecting reversal of the screw while the latter stops the feed movement. The turret is indexed by a roller 15 on the cam disc 16 engaging a Geneva wheel 14 secured to the turret spindle. The shaft 17 for driving the indexing and locking mechanism rotates continuously and is coupled to the shaft 18 for driving the disc 16 by a stop 32 on the feed sleeve 29 which, at the same time as the stop 35 is operated to stop the lead screw, actuates through linkage a one-revolution clutch 20 which thus enables shaft 17 to drive the indexing mechanism one revolution and index the turret through one station. A cam 19 on the shaft 18 lifts the locking plunger 31 against a spring 25 just prior to the indexing movement. Spring-pressed latches 36 retain the tool-slides against movement in their withdrawn position until a new feed movement is commenced. Specifications 595,974, [Group XXIV], and 626,614 are referred to.

Title: Torsion damping device for use on motor-vehicles
IPC: B60R19/48
Filed: 1933-06-23
Abstract: 410,983. Vibration-dampers; vehicle collision-guards. ROVER CO., Ltd., and WILKS, M. C., Helen Street, Coventry. June 23, 1933, Nos. 17932 and 36334. [Classes 103 (ii) and 108 (iii).] To damp torsional vibration of a vehicle about its longitudinal axis when travelling a flexible transverse member with weighted ends is mounted on the vehicle, the member being damped against movement and connected if desired to a bumper bar. As shown, a flexible transverse member comprising a leaf spring having two laminations 16, 17 is pivotally mounted on the ends of the vehicle longitudinals 11 by means of bushings 12 having rubber rings 14, bolts 15 and clips 18. The ends of the transverse member are weighted so that the natural frequency of the device is substantially equal to the torsional frequency of the vehicle about its longitudinal axis. To this end weights 19 are secured to the ends of the transverse member by bolts 22, nut 23 and cover nut 24. In some arrangements the ends of the bumper bar are formed as a housing 21 around the weights or around a housing 26 formed on the ends of the transverse member. Unwanted frequencies are damped out by means of friction between the laminations which, if spaced apart, may have friction pads 30 introduced and the spacing at the pivoted parts may be varied by spacing washers 29. The bumpers 20 may bear on rubber pads 27 carried by the bushings 12.
