Filed: 1944-04-13
Abstract: 582,050. Broaching. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.). April 13, 1944, No. 6827. [Class 83 (iii)] In a machine for broaching tubular work, the work is supported in' a holder which is movable to align either the work or a broach return tube with the puller head so that the broach may be returned whilst a new work- ' piece is being mounted in the holder. The holder comprises a hollow shaft 10 mounted in fixed bearings 11, 12 and carrying brackets 20 provided with radially adjustable work-supporting screws 15. A sector-shaped end plate 24 on shaft 10 is guided for swinging movement with the shaft at 27 and carries a work-holding chuck 26. A stationary hydraulic cylinder 31 has its piston attached to a slide 33 connected by a link 34 to the plate 24 to oscillate the plate, shaft 10 and brackets 20 against one or other of the stops 28, 29 and thus align either the work W or a return tube 21 mounted in the brackets and plate with the puller head 40. The rear end of the work is supported by a hollow tailstock 50 slidable within the limits of a pin and slot 71 in a casing 51 which is movable axially on guideways in the trough-like frame 36 by means of a chain 61 passing over stationarily mounted sprockets 57, 59, the sprocket 57 being rotatable by a hand wheel and locked in adjusted position by a ratchet 63. A tubular extension 75 is mounted on a carriage 77 slidable on a guide rod 78 and may be locked to the tailstock 50 by a hand lever 80 and a toggle connection 82. In operation, after the head 40 has pulled the broach completely through the work W, the hand lever 80 is operated to release the extension 75 which may then be withdrawn clear of the tailstock 50 and swung about the guide 78 out of alignment with the work. The casing 51 is then retracted by the chain 61 and the cylinder 31 operated to swing the shaft 10 &c. away from the position shown in Fig. 3, thus allowing the broach to be returned through the tube 21 and a new work-piece to be mounted in the chuck 26 and brackets 20. The cylinder 31 is next actuated to return the shaft 10 to operative position, the reduced end of the broach, which has remained in the tailstock 50, is passed through the work to engage the head 40, the tailstock is advanced to engage the work, compressing a spring 70 between the tailstock and casing 51 until the ratchet 63 engages an appropriate tooth with its pawl, the extension 75 is aligned with the work and locked against the tailstock by the lever 80, and the broach may then be pulled through the work on its cutting stroke. Lubricating and cooling cutting-tools.-Oil under pressure is supplied to the tailstock 50 by a pipe 79, flows through the channels between the lands of the broach and passes out from the front end of the work into the .casing 36.

Title: Improvements in or relating to ratchet driving mechanisms
IPC: G05G15/04
Filed: 1927-03-14
Abstract: 292,224. Automatic Telephone Ma.nufacturing Co., Ltd., and Smith, S. R. March 14, 1927. Driving means.-For recording the running and idle times of machinery by electrical impulse sending mechanism operated through reduction gearing, the impulse sending mechanism is driven by a pawl 13, Fig. 2, which itself is driven by a crank or eccentric 12 from the machinery, and is lifted clear of its associated ratchet-wheel 15 during part of its movement by a stop 19 which is detachably mounted. Two alternative positions 19, 19<1> for mounting the stop are provided and used according to the direction of rotation of the eccentric. To the ratchet-wheel 15 is attached a double toothed gear wheel 22, Fig. 5, driving a pinion 23, Fig. 4, to actuate a gear wheel 26 in the manner of a Geneva type transfer mechanism. Integral with the wheel 26 is a multilated gear wheel 24 adapted to drive a wheel 29 and wind up a spring arranged in a cap 30. Attached to the wheel 29 is a sector-shaped cam disc 31 which co-operates with two contact brushes 32 mounted on a pillar 43 and normally maintained apart by an insulating strip 33. When the spring is being wound the inclined edge of the cam disc deflects one of the brushes, the disc passing on the outside thereof, but when the multilated part of the wheel 24 permits the spring to return the wheel 29 the other edge of the cam disc engages between the brushes, thus completing the circuit, through the insulated terminals 38 to the electromagnet of the recording mechanism. The return movement is controlled by a centrifugal or similar governor 34 driven by the wheel 29. For machines of different speeds the reducing gear can be changed accordingly, as by interchanging the wheel 22 with one having the requisite number of teeth.

Title: Improvements in machines for wrapping cigarettes and similar articles
IPC: B65B19/02
Filed: 1923-03-12
Abstract: 214,792. Molins, W. E. March 12, 1923. Packeting by wrapping-up. - Relates to machines for wrapping bunches of cigarettes or confectionery &c. in block form, in foil, paper, &c. According to the invention, a partially-folded packet is gripped by high-speed rollers as it issues from a folding-box, and is fed forwards in advance of its plunger or conveyer piece, thus gaining time for tucking-mechanism associated with the rollers to operate on the open end of the packet. As shown, a bunch of cigarettes is pushed by the members .of a conveyer into contact with foil at C and wrapped in a folding box 1. Rollers 2, rotating at a greater peripheral speed than that of the conveyer, engage the sides of the packet and move it away from the conveyer member. Each roller is shaped like a shallow dish and carries a pawl 3 held normally in the position shown in Fig. 2 by springs 5. Bands 6 of rubber &c. are disposed around part of the circumference to afford a gripping surface. As the rollers rotate, the ends of the pawls 3 form and tuck in the narrow side flaps at the open end of the packet D. On continued rotation of the rollers the pawls engage the ends of guides 8 and are pushed into an inoperative position in recesses 7. The packet is then momentarily stationary within the guides 8 and a cam-operated tucker 9, Fig. 1, descends to turn down the upper broad-end flap. A spindle 18 on the conveyer then raises an arm, pivoted at 17, the end of which turns up the lower broad flap. The packet is steadied for these operations by spring-held stop 19 which rises when the conveyer member overtakes the packet and feeds it to the left, for example, through a mouthpiece 22 and into a shell 23. If the cigarettes are to be packed in a two-piece slide and shell box, the tuckers 9, 16 are omitted and the broad-end flaps folded as described in Specification 169,341, the top broad flap being folded down by a camoperated pusher co-operating with rollers corresponding to the rollers 19 of that Specification. The tuckers 9, 16 may carry rollers, and may be adapted to gum the flaps as they are turned in. One tucker may be omitted and the final fold made by pushing the packet into a stacker. Specifications 165,891 and 167,255 also are referred to.

Title: Making woollen materials non-felting and soft
IPC: D06M13/395
Filed: 1940-04-19
Abstract: 540,613. Treating textiles with liquids. BALDWIN, A. W., LAWRIE, L. G., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 19, 1940, No. 7107. [Class 15 (ii)] Wool is rendered non-felting and of a soft handle by treating it with an isocyanate of the formula :-R-X-NCO, wherein R is an alkyl radical of at least 8 carbon atoms and X is the divalent radical -CO-O-CH 2 -CH 2 - or is absent, and also treating it, before, during, or after the isocyanate treatment, with a reactive sulphur compound which is acid or is capable of liberating sulphuric or hydrochloric acid on hydrolysis with water, this treatment being so adjusted that the wool is not appreciably weakened. The isocyanate is preferably applied in the form of a solution or dispersion in an inert or relatively inert liquid, e.g. water, benzene, carbon tetrachloride, or white spirit. If it is applied as an aqueous emulsion before the treatment with the reactive sulphur compound, the wool must be dried between the two treatments. In an example, woollen yarn is immersed in a solution of octadecyl isocyanate and sulphuryl chloride in carbon tetrachloride. It is squeezed, rinsed in water, immersed in dilute ammonia, washed with water, and dried. Pentatriacontanyl isocyanate, stearyloxyethyl isocyanate, or tricosyl isocyanate may be used instead of octadecyl isocyanate. In another example, woollen yarn is immersed in a solution of sulphuryl chloride in carbon tetrachloride. It is squeezed and then immersed in a solution of octadecyl isocyanate in carbon tetrachloride. It is squeezed, washed, and dried. Specifications 464,503, 480,775, and 483,707 are referred to.

Abstract: 679,042. Valves. SLINGSBY & CO., Ltd., W. Sept. 18, 1950 [March 22, 1950, June 12, 1950], Nos. 7163/50 and 14605/50 [Class 135] A vent pipe for tanks comprises an inverted cup-shaped piston valve 35 slidable in a liner or cylinder 32 ported at 33 and displaceable automatically according to the pressure in the tank, the valve and cylinder being carried by a body 28 and shrouded by the member 29 to prevent the inlet of water. As the piston moves upwards against its weight or a spring the skirt 38 uncovers the cylinder's ports. On moving downwards against a spring 36, piston ports 41 overlap the cylinder ports and allow air to enter and relieve the vacuum. The valve may be lifted by the handle 43 and retained in this position by a pin 22 passing through a hole 21 in the handle. The ports may be covered with a wire mesh 44 to prevent ignition of inflammable liquid in the tank. In another embodiment only the cylinder is ported, the valve has no loading spring, the wire mesh is supported within the cylinder on a carrier and a vacuum in the tank is relieved by air entering through holes in the top of the piston to give an audible whistle. The holes may be controlled by spring- loaded valves.

Title: Improvements in and relating to carrier wave transmission systems
IPC: H03C1/60
Filed: 1934-03-07
Abstract: 431,591. Wireless transmitting systems. WILSON, W. P., 28, Wyatt Park Road, Streatham Hill, London, and MURPHY, F. M. G., Orchard Lodge, Chelmsford, Essex. March 7, 1934, No. 7313. [Class 40 (v)] In a single side-band transmitting - system, the signal band is divided into two or more frequency ranges or sub-bands, each of which is stepped up in frequency to a different extent by modulation followed by side-band selection. These side-bands are then rendered contiguous by one or more further modulations so as to form a complete band, which is then stepped up to the desired radiating frequency. The pure carrier may or may not be radiated. As shown, the signal passes from a volume control VC associated with a volume indicator V1 to an amplifier SA from which different bands of frequency are selected by filters AF1, BF1. The upper band is modulated at BM1 with a wave from a channel B01, and one side-band is selected by a filter BF2 and passed through an equalizing network BE2 to a pre-combining amplifier CA. The lower band is modulated at AM1 by a wave from a source AO1 and a side-band is selected at AF2 and passed through a network AE2 to a further modulator AM2. The output from this modulator is filtered and combined in the amplifier CA with the output from the B channel. The wave supplied to modulator AM2 is derived by adding the frequency of the wave from AO1 to that of the channel BO1 in a modulator DM2, this having the effect of bringing the partial side-bands of the A and B channels into contiguity so as to form a complete side-band. The latter is again raised into the range of the transmitting carrier by modulation at CM1 with a wave from a source CO1 followed by a side-band selection at CF1. The carrier itself is generated at MO and after amplification at MOA may be combined with the side-band by applying them respectively across the diagonals of a bridge arrangement having the combined output taken from one arm of the bridge and applied to the aerial through an amplifier CA1. The frequency supplied by the channel BO1 to the modulators BM1, DM2 is derived as the difference frequency between the sources MO and CO1 by a modulator DM1 and filter DF1. In this way the radiated sideband and the radiated carrier wave are kept in proper frequency relation. As an alternative arrangement, the frequency supplied to modulator CM1 may be derived as the difference between the carrier frequency of source MO and an independent source supplying the channel BO1. The various frequencies required may be derived as harmonics of a common fundamental source. The Specification discusses the limits of the frequencies of the various oscillators, having regard to economy in filters and to the harmonic production inherent in modulations. Numerical examples are also given.

Atmospheric air passes into a chamber 2 of a drying cabinet 1 through a nozzle 16 by passage from an inlet 17 in a conduit 4 between the chamber and cabinet walls, which conduit houses a heat exchanber tube 5 supplied with hot air from the interior of the chamber through an opening 15 by a rotary compressor 11 in a chamber 10. The compressed air exits to atmosphere from the tube 5 via a decompressor 8 and outlet 9 which has a dehydrating device (not shown) to remove condensed water carried by the low temperature air. In a modification, Figs. 2 and 3 (not shown), air from the cabinet passes to the compressor for heating and is thereafter divided into two portions, of which one passes back to the cabinet and the other passes to the heat exchanger to heat the incoming atmospheric air. This portion is thereby cooled and looses its water vapour content by condensation. In the embodiment of Fig. 4, a panel 24 formed by one side of the cabinet supports a casing 25 having a heating element 27 adjacent an upper outlet 26 through which a major portion of air from the cabinet is induced by a fan 29 in the lower end of the casing, a portion of the induced air passing into a casing 32 for passage over a cooling element 34 in order to condense water vapour which is collected in a sump 37. In another embodiment, Figs. 6 and 7 (not shown), the heat exchanger which causes the condensation of the water vapour is placed directly in the casing 25.
