Title: Improvements in or relating to heel-breasting machines
IPC: A43D87/00
Filed: 1939-05-19
Abstract: 529,514. Heel breasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., and BARKER, W. A. May 19, 1939, No. 14906. [Class 17 (i)] The heel is positioned with the aid of gauges , and clamped to a holder which is then swung into operative position beneath the knife. Power operated means for actuating the knife cannot be engaged except when the heel is in operative position. On return to the loading position remote from the path of the knife the heel is ejected and blasts of air produced for the removal of chips from the machine. The knife has a movable guard. The holder for the heel H is pivoted at 17 and moved by a handle 23 between loading and breasting positions. The sides of the heel are engaged by gauges 37 which may be separated or brought together by a hand-operated knob 51. The rear of the heel is positioned by a gauge 27, adjustable by a knob 31. The heel breast is positioned by fingers 45, geared together, held in adjusted position by the friction of a leaf spring, and carried by a lever 47. When positioned, the heel is held by a clamp 53 on a lever depressed by a link 61 threaded into a pin 63 carried by a pair of plates 65 pivoted at 67 and urged clockwise in Fig. 4 by a lever 73 pivoted to the handle 23. A spring 77 releases the heel when allowed. To prevent the clutch being engaged to depress the knife 25 unless the heel is in operative position, the work support carries a curved member 85 normally preventing an axially slidable rod 83 from moving to the left in Fig. 2 under the pull of a spring 87. This rod is adjustably pivoted to a lever 97 formed with an extension 101 normally preventing a lever 105 being depressed, this lever being that depressed by treadle to engage the clutch.. The lever 97 carries a latch 129 co-operating with a latch 115 which first frees and then lifts the lever 105. A link 141 moves with the rod 83 to produce blasts of air by a spring actuated piston from a cylinder 139 as the heel is swung back to work changing position, nozzles 162, 164 directing the blast. A curved work ejector 163 is carried by a lever 49, carried by the lever 47 carrying the fingers 45, this lever being swung by a pawl 175 carried by the heel holder and engaging a surface 173 to actuate the ejector and then sliding off the same to allow it to be returned by a spring. A pivoted guard 177 shields the knife. Arc shaped guides 13 allow the work support to be adjusted about a virtual axis to adjust the angle of the breasting cut. The support is clamped in adjusted position by a handle 15. Specification 17260/09, [Class 17 (i)] is referred to.

Title: Preparation of non smooth films for use as sound or talking films
IPC: G11B27/06
Filed: 1930-05-16
Abstract: 355,259. Combined sound and picture films. RICHARD, A. A. P., 97, Rue Lemercier, Paris. May 16, 1930, No. 15146. Convention date, Feb. 22. [Class 40 (ii).] Relates to the treatment of kinematograph films such as are used in colour photography, having embossed striations or lenticulations thereon, in such a manner that a portion of the film bearing or intended to receive a sound record is rendered smooth. The smoothing is effected, according to the invention, by applying to the sound-record area of the film a solvent, which dissolves the embossed striations or the like. Apparatus for effecting such treatment comprises a roller D, between which and a resilient support H the film E is moved, the solvent being applied to the periphery of the roller and thereby brought into contact with that part of the film which is to be smoothed. The roller is grooved at F to accommodate excess of the liquid. Blowers G are arranged to prevent the solvent from affecting the parts of the film where smoothing is not desired, and these parts may be coated with a protective varnish. The Specification, as open to inspection under Sect. 91 (3) (a), describes also a device for smoothing out embossed striations along a narrow band on the film by means of a heated roller over which the film is passed. At both sides of this roller, non-conductive rullers, cooled by fluid, are disposed, and resilient supports engage the film at the side opposite the rollers. This subject-matter does not appear in the Specification as accepted. Specification 347,044 is referred to.

Title: Improvements in resistance-capacity coupled thermionic valve low frequency amplifiers
IPC: H03F1/54
Filed: 1940-10-25
Abstract: 544,103. Valve amplifying circuits. BRITISH THOMSON-HOUSTON, CO., Ltd., and MOIR, J. Oct. 25, 1940, No. 15672. [Class 40 (v)] In a resistancecapacity coupled ampli. fier having coupling elements between stages providing high time constants in the grid circuits, in order to reduce the time period necessary to place the amplifier in operating condition after the initial application of operating potential the grid leak resistance of the valve in the second and subsequent stages is replaced or shunted by a voltage dependent resistor. As shown the grid leak R2 is shunted by a rectifier RU1, which may be in series with a battery or other source of potential B of opposite polarity to that applied to the resistor RU1 from the H.T. source, but the direction of current flow through the rectifier RU1 produced by the source B is the same as that produced when the switch S1 is closed. The rectifier RU1 is thus conditioned and rendered capable of more quickly allowing the condenser charging current to flow through it. The rectifier RU1 may be constituted by the resistance material described in Specification 292,110, [Class 38 (ii)], by selenium sulphide, or by a diode. Specification 480,209 also is referred to.

Filed: 1975-04-17
Abstract: 1498668 Lirikwork AMP Inc 7 April 1976 [17 April 1975] 15841/75 Heading F2K A rotating cutting drum 11 in a tobacco cutting machine (not shown) is carried by a frame 19 pivotally mounted at a pivot 20 on stationary machine housing plates 32, 34, the frame 19 and hence cutting drum 11 being pivotally moved between the closed position (Fig. 2), shown in full at 19, and on open position (Fig. 2), shown chain-dotted at 50, by a link drive 26, 29 the latter link of which is oscillatably driven by a shaft 40 of a pneumatically driven quadrant actuation 38. The opposite end of shaft 40 carries a gear section 41 which meshes a similar gear section 44 coupled to a return coil spring unit 37. Eccentricallymounted on each gear section 41, 44 is a pin 46 and 47 between which extends a piston and cylinder shock absorber 49 which has a high resistance to contraction as compared to a relatively low resistance to expansion. The arrangement is such that during the initial opening or initial closing movement of the frame 19 and drum 11 via the pneumatic actuation 38 or return spring unit 37 respectively, as the shock absorber is moved from position 49 shown in full (Fig. 2) to position 52 shown chain dotted or vice-versa, the shock absorber 49 is extended and thus offers low resistance to enable a speedy initial opening or initial closing movement to be effected, whilst during the final phase of the opening or closing movement, the shock absorber 49 is compressed to offer high resistance to effectively damp the final phase of movement.

Title: Improvements in or relating to statistical machines
Inventor: ENGLISH FRANCIS GUY SYDENHAM
Filed: 1950-06-26
Abstract: 679,231. Statistical apparatus. POWERSSAMAS ACCOUNTING MACHINES, Ltd. May 10, 1951 [June 26, 1950], No. 15948/50. Class 106 (i). The apparatus according to the invention comprises improved apparatus for verifying cards which are double punched in two stages with the card slightly displaced at the second punching so as to form an oval hole from two overlapping circular punchings, and which are punched in both normal and interstage horizontal rows. The combination on one card of the features of interstage recorded data 12, i.e. additional holes punched in the spaces between normal horizontal rows 11, Fig. 1, and the oval holes 15, 16, resulting from checking by double punching gives rise to the necessity for reducing the size of the double punched oval holes to avoid overlapping of adjacent holes. The method of double punching for verification is described in Specification 363,431 and apparatus for testing such cards is described in Specification 362,770. A set of pins 32 is provided for each vertical column and are actuated by two lower portions 17, 18, disposed in endwise abutting relationship. The lower portion 18 of each pin is formed with an oval shank 29 and tapering shoulders 30 leading to a circular tip of smaller diameter 31. The intermediate portions 17 are each provided with a horizontal pin 23 which engages in one of the slots 24 in a testing plate 25. The card to be checked is placed in the sensing chamber formed between plates 26, 27, and is located by a card stop 28. When the pins are brought into contact with the card the pins will assume positions shown in Fig. 2, according to the state of the punching in the card. Thus, where there is no hole the pin as shown at C will rest on the card and the horizontal pin 23 is clear of the abutment in the slot 24. Where two punching operations have produced an oval punching showing that the data has been correctly verified the shank 29 of the pin passes through the card as shown at B. The intermediate portion 17 following the portion 18 descends and the horizontal pin 23 is again clear of the abutment in the slot 24. Where, however, a circular hole remains after the second punching showing that the data has not been correctly verified the tip of the member 18 passes through and the shoulders 30 rest on the sides of the hole preventing the shank 29 from entering as shown at A. The resulting partial movement of the member 17 brings the horizontal pin 23 into line with the abutment of the hole 24 so that when the testing plate 25 is moved longitudinally it is prevented from making its full normal travel by the pin 23. This obstruction is used to give a signal to the operator that an incorrectly punched card is in the sensing chamber.

Abstract: 1,194,486. Production and handling of films. CELANESE CORP. 3 April, 1968 [10 April, 1967], No. 16952/68. Heading B5B. In an apparatus for producing or handling an electrically insulating film, in which the film is pressed against a metallic surface by force arising from an electrostatic charge applied to the film, the electrostatic charge is developed by an ionizing discharge between an electrode connected to one terminal of a high voltage source and both an electrically conducting element connected to the other terminal of the high voltage source and the metallic surface, the latter surface being connected to the element by a current limiting resistance and being situated closer to the electrode than is the element. The element is preferably a film extrusion die arranged to deposit film extruded on to the metallic surface of a rotatable drum, and is connected with the corresponding terminal of the high voltage supply to earth. As shown, the film extruding plant comprises an extruder die 10 electrically earthed, a casting drum 12 upon the polished surface of which the film from die 10 is deposited and a take-off roll 18. The rotatable drum 12 is earthed through a current limiting resistance R 3  which avoids arcing between the electrode and the metal surface. The positive terminal of a high voltage direct current supply 16 is connected directly to electrode 14 and its negative terminal to earth. Film extruded from die 10, in travelling to drum 12, collects a positive charge and is attracted to the drum's surface and pressed against it.
