Title: Improvements in or relating to wrapping, parcelling or boxing machines
IPC: B65B35/54
Filed: 1939-10-25
Abstract: 533,855. Packing. MOLINS, D. W., BING- HAM, A., and MOLINS MACHINE CO., Ltd. Oct. 25, 1939, No. 28669. [Class 94 (i)] A machine for enclosing a number of articles in a wrapper or box is provided with means for feeding separate articles, such as packets of cigarettes, towards a wrapping or boxing mechanism in separate paths which converge or overlap so as to assemble the articles in superposed relationship, the means enabling the articles to be inspected prior to enclosure in the outer wrapping or box. The packets of cigarettes 1, Fig. 2, are lifted by a vertical stacker composed of a reciprocating platform 20 and intermittently moving bands 19. The packets are removed in pairs from the top of the stack by a reciprocating pusher 3 which moves them over a plate 4 and delivers them to another reciprocating pusher 5, Fig. 4, moving at right angles to the first pusher. The pusher 5 moves the upper packet of a pair horizontally on to a plate 6 at a higher level than the plate 4, and into the path of a third pusher 7. The plates 4, 6 extend away from the stacker, and the packets are pushed along them by the pushers 3, 7 to form two parallel horizontal rows, one at a higher level than the other. Endless belts 8, 9 may be provided, in place of the intermediate portion of each plate, to move the packets. During this movement, the packets may be inspected and defective ones removed. At the end of the belts, the rows of packets move into pairs of guides 10-11 and 12-13 that are bent to form curved passages in vertical planes and lead to travelling bands 14-15 on which the packets are delivered in an inverted position. These bands converge towards one another until one band, 15, lies above and partly overlaps the other band, 14, in front of the parcelling or boxing mechanism, as shown in Fig. 5. In this position, the packets are engaged by a detecting apparatus composed of pins 89, slidable in metal bushes in a plate 88 of insulating material that reciprocates vertically. The absence of a packet from a row causes a pin to complete the electric circuit, through a make-and-break switch 95 Fig. 1, of a magnet 96 which opens a clutch 106, 107 and disconnects the machine from the driving shaft. From the position shown in Fig. 5, an assembled batch of packets may be thrust by pushers 65, 66 into a pre-formed box, as described in Specification 511,616. The batch may also be enclosed in a box blank 109 which is fed downwards in front of the batch, the package being folded and sealed in the known manner.

Title: Improvements in and relating to electric discharge devices
IPC: H01J17/00
Filed: 1950-11-23
Abstract: 695,481. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 23, 1950 [Dec. 1, 1949], No. 28675/50. Drawings to specification. Class 39(i) An electric discharge tube of the low pressure positive column type for the generation of sharply peaked sawtooth current pulses, or as the current source for a flashing light signal, has a filling of mercury, argon (or another suitable rare gas) at a pressure of a few millimetres, and a polyatomic gas such as nitrogen, carbon monoxide or hydrogen, at a pressure between 0.1 and 20 microns; the arc discharge current is maintained between 0.01 and 2 milliamperes per square centimetre of the crosssection of the tube. It is stated that xenon is unsuitable for the rare gas constituent, but that one or more of the rare gases helium, neon or krypton may replace the argon. A preferable filling for a discharge tube 4 feet long and 1¢ inches in diameter, is mercury vapour, argon, and nitrogen at a pressure of 3.5 microns. It is stated that the addition of the polyatomic gas changes the character of the discharge from a low voltage arc with running striations to a discharge which flashes on and off periodically, the current showing a sharply peaked sawtooth waveform. The frequency of the current pulses i.e. the flashing, may be controlled by the value of a ballast resistor. The frequency may be raised by increasing the ratio of nitrogen to mercury vapour, or by increasing the current and decreasing the pressure of the argon. The flashing discharge may or may not be visible to the naked eye. The discharge tube may be of coiled or helical shape. The tube may be supplied from a D.C. or A.C. source, or from an A.C. source having a constant amplitude peak, and the electrodes may be of the thermionic type, or cold cathodes. The pulse controlling discharge circuit may be connected to the load circuit through a resistance or transformer coupling which may involve a triode amplifier. Specification 639,013 is referred to.

Title: Purification of aromatic hydrocarbons by azeotropic distillation
IPC: C07C7/06
Filed: 1939-10-26
Abstract: 536,172. Distilling hydrocarbons. WOODALLDUCKHAM (1920), Ltd., SPIERS, H. M., and SUTTLE, H. K. Oct. 26, 1939, No. 28710. [Class 32] Pure or nitration pure aromatic hydrocarbons boiling below 150‹C. e.g. benzene, toluene, xylenes, are obtained from impure raw material. comprising mainly one such hydrocarbon and a plurality of non-aromatic hydrocarbons, by azeotropic distillation with an aliphatic alcohol containing not more than three carbon atoms in the molecule, e.g. methyl alcohol, so that the non-aromatic hydrocarbons having boiling points up to about 15‹C. higher than the boiling point of the aromatic hydrocarbon are vaporized at a temperature below the boiling point of the latter and removed with the alcohol, while a residue is obtained of the aromatic hydrocarbon and impurities boiling more than 15‹C. above the boiling point of the aromatic hydrocarbon, which impurities are removed by simple fractional distillation. In a modification methyl alcohol is added to the impure raw material in an amount less than that required to bring over all the hydrocarbons and the mixture is fractionally distilled to obtain at progressively increasing temperatures mixtures containing alcohol and low boiling non-aromatic hydrocarbons, a mixture of water and pure aromatic hydrocarbon, and a residue of aromatic hydrocarbon and high boiling hydrocarbons. The water is separated from the aromatic hydrocarbon which is added to the residual fraction which is then re-fractionated. The free-runnings containing alcohol may be used for treating a further batch of raw material. Examples are given of the distillation of impure toluoles. Specifications 464,307 and 513,566 are referred to.

Title: Accordion folding apparatus for paper
IPC: B26D1/02
Filed: 1972-06-20
Abstract: 1369891 Folding and cutting webs WESTVACO CORP 20 June 1972 [31 Aug 1971] 28867/72 Heading B8R A zigzag folder for a web W, Fig. 1, comprises two pairs of chains 3a, 3b, running on adjacent closed paths and each carrying at least two grippers 36 and two tuckers 35, arranged so that a gripper on one chain pair is aligned with a tucker on the other chain pair in the zone A, so that the tucker pushes the web into the gripper to form a crease, alternate creases being of opposite sense. Each gripper comprises two elastomer jaw elements 62, Fig. 3, attached to adjacent links so as to be opened when the links are on a curved part of the path. Rollers 34 have recesses 38 to accommodate the rollers 37 of the chains to prevent opening of the grippers at that point. The web is deposited in zigzag form in a hopper 9. If it is desired to cut the web into separate lengths along some of the crease lines after folding, there is associated with the folder a cutter comprising reciprocating tables 41a, 41b, carrying blades 43a, Figs. 1 and 6, 43b, and co-operating roller cutter units 42a, 42b. In operation, to cut along the crease line between web sections W 4  and W 5 , the roller cutter unit 42a is raised to operative position, the knife 43a is advanced to grip the web between it and the rollers 44, and the rollers 44 are moved across the web on a chain 46. Reverse creases are cut by the blade 43b and roller unit 42b. The web may alternatively be cut into separate lengths before folding, by rotary cutters 17, 18, Fig. 12, cutting two webs supplied from separate rolls 10, 11, the cutters being synchronized so that where the sheets come to a common path 21 the gaps between pairs of sheets from the two sources are staggered. A tucker on the right-hand chains engages the gap between a pair of sheets from roll 10, and the mid-line of a sheet from roll 11, so that at each fold line the outer sheet is folded round a gap between the inner sheets. The roller cutter units, Fig. 6, may be replaced by units wherein the rollers are frustums of cones and the roller assembly is oblique to the blade 43a, or by a segmental cutter 86, Fig. 10, which rolls against the blade when a pin is moved in a slot 88. The blade edge may be undulating to produce scalloped edges. Specifications 1,369,892 and 1,369,893 are referred to.
Patent GB-311520-A (GB)
Title: Means for controlling the intensity of a beam of light for use, for example, in recording sound
IPC: G11B7/00
Filed: 1928-07-04
Abstract: 311,520. Whitaker, A., and Gramophone Co., Ltd. July 4, 1928. Photographic recorders.-Relates to means for controlling the intensity of a beam of light in accordance with mechanical oscillations, for recording sound and for like purposes. According to the invention, a beam of polarized light is passed through a body which, when unstressed, is isotropic, and mechanical stresses corresponding to the sound or other oscillations are applied to the said body, such stresses not being uniformly distributed, and the light beam being passed through the body at or approximately at the position of maximum stress. Variations in the transmitted light produced by this means may be recorded photographically. In the arrangement shown in Fig. 1, a parallel beam of light from a source 1, which may be monochromatic, is directed through two polarizing prisms 3, 4, between which is placed a body 5 which is isotropic when unstressed, and may for example be made of glass, celluloid, or the material known by the registered Trade Mark " Xylonite." One end of this body is fixed at 6, and the other carries a coil 7 arranged in an annular gap between magnetic pole-pieces 9, 10. The prisms 3, 4 may be so arranged that when the body 5 is unstressed, light is wholly or partially prevented from passing through to an optical system 11 which coacts with a slit 12 past which a film 13 travels. When acousticallyvarying currents pass through the coil 7, stresses are produced in the body 5, which is so shaped that the distribution of stress is not uniform, and the position of maximum stress lies in the path of the beam of light. The varying stresses have the effect of enabling light to pass through the prisms with corresponding variations in intensity, and the variations are recorded on the film. Fig. 3 shows a modification wherein two isotropic bodies 14, 15 are used. These parts, which may be of glass, are pressed into point or linear contact with each other by springs 16, the general arrangement and action being similar to that previously described. Instead of applying stresses electromechanically to the isotropic body, mechanical oscillations may be applied directly; or the oscillations applied to the body may be highfrequency oscillations modulated by acoustic or other relatively low-frequency mechanical oscillations. Further, two quartz crystals may be used in combination, the crystals being such that they act in opposite senses as regards rotation of the plane of polarization of the light. The combination thus acts as an isotropic body. In another arrangement, a piezo-electric crystal, or a battery of such crystals, is used, in conjunction with apparatus of the kind described above. Changes of shape in the crystal or crystals, caused by the application to their faces of potential variations, are transmitted to the isotropic body whereby the beam of polarized light is influenced.

Title: Improvements in and relating to spark ignition systems for internal combustion engines
IPC: F02P3/08
Filed: 1959-08-25
Abstract: 861,690. Ignition systems. GENERAL MOTORS CORPORATION. Aug. 25, 1959 [Sept. 12, 1958], No. 29025/59. Class 7(4). [Also in Group XXXV] In an ignition system a transistor oscillator circuit having at least one transistor and adapted to be energized from a source of direct current has its output terminals connected by way of at least one rectifier with an energizing circuit which is connected to the primary winding of an ignition tranformer and is controlled by a circuit including an electronic switch. As shown the transistor oscillator circuit 10 includes a pair of transistors 20, 24 which become conductive alternately. The oscillator operates as a selfexcited generator of alternating current which may have a frequency in a neighbourhood of 20,000 cycles per second. The AC voltage supplied by the secondary winding 40 is rectified by silicon diodes 104 and 102 and thus appears as direct current voltage between lead 108 and earth. This DC voltage causes current flow through inductance 128 to condenser 130 and through primary winding 95 of the ignition coil to earth so that condenser 130 will build up a charge of the polarity indicated in the Figure. When the breaker contacts 148 open a high voltage is induced in the secondary winding 140 of transformer 142 and this voltage is applied to the grid of tube 132 through resistor 138. This voltage causes conduction of the tube 132. with the tube 132 conducting the condenser 130 discharges through a circuit that includes the primary winding 95 and the tube 132. The tube 152 is used to drain off the residual charge that appears across condenser 130 after it discharges. In order to start the engine switches 18 and 58 are closed. Contacts 62, 68 and 70 are started together and a circuit is completed for the starting motor 60. In addition relay coil 74 is energized to move the armatures 76 and 78 to positions in contact respectively with switch contacts 82 and 83. The movement of relay armatures 76 and 78 from their normal positions applies a greater potential to the primary winding of transformer 142. The secondary winding 120 will in practice be connected with a plurality of spark plugs through an ignition distributer mechanism (not shown). Specification 861,689 is referred to.

Filed: 1933-10-20
Abstract: 429,260. Spray carburetters. NEESEN, A., 40A, Cecilienstrasse, Zehlendorf - Mitte, Berlin. Oct. 20, 1933, No. 29064. Convention date, Nov. 12, 1932. [Class 7 (iii)] To test a carburetter, a nozzle 2, similar to a fuel nozzle, is connected to a pressure-measuring device and introduced into the mixing - chamber so that its orifice lies near the discharge orifice of the fuel nozzle 1. The suction is measured at various speeds, and the quantity of fuel which has been delivered is compared with that known to be necessary. Small quantities of air may be introduced near the jet orifice to prevent the formation of eddies. If these quantities differ, the fuel nozzle and the auxiliary nozzle are interchanged and the tests repeated. If the quantity of fuel delivered varies the fuel nozzle is faulty. If the vacuum fluctuates the presence of turbulence is indicated. The Specification explains how the tests are carried out when the fuel is supplied to the nozzle under pressure.

Title: Improvements in or relating to staple driving machines
IPC: B25C5/16
Filed: 1935-10-23
Abstract: 453,383. Stapling. POLZER, F., South Norwalk, Connecticut, U.S.A. Oct. 23, 1935, No. 29270. Convention date, April 27. [Class 89 (iii)] A machine for stapling or tacking, which may be of the desk or pliers type, is provided with means whereby a staple may be correctly driven even if its cross-bar is crooked and /or its legs are inclined forwardly or rearwardly. The machine shown comprises the usual base 11, body 12, head 14, driver plunger 16, staple bar 18, and pusher 22 with spring 21. The forward end of the bar 18 has its upper edge bevelled back from its centre, as at 27, Fig. 15. A staple 20a whose cross-bar is not perpendicular to the axis of the bar thus lies across the driver passage 15 with its rearward side above a bevel 27. When the driver engages the cross-bar, this rearward side is cammed forwardly by the bevel, so that the cross-bar is correctly positioned beneath the driver. The lower end of the driver passage is closed at the front by a block 19 in which is pivoted a lever 33 adapted, whilst a staple is being driven, to force back the remaining staples on the bar 18. The lower wall 36 of the block 19, Fig. 6, and the ribs 18a of the bar 18 are cut away to provide spaced recesses 37 in rear of the passage 15. If a staple has its legs 20c inclined rearwardly, they enter the recesses 37, which allow the staple to be driven. During driving, the frictional engagement of the staple cross-bar with the lower arm 34 of the lever 33 tends to rotate the cross-bar in a direction to move the legs 20c forwardly into correct driving position in the passage. The block 19 is locked in position by a shoulder on the bar 18. To provide for staples having their legs inclined forwardly, spaced slots 38 having incurved lower ends 39 are provided in the block 19, Fig. 9. The legs 20e are straightened by the surfaces 39, so that the staple assumes a correct position for driving. Slots 40 may be provided opening laterally from the slots 38, Fig. 17, to permit the ejection of broken staples and the clearing of staples jammed in the driver passage. Specifications 453,384 and 453,385 are referred to.
