Title: Improvements in or relating to coin-freed vending machines
IPC: G07F11/10
Filed: 1928-03-24
Abstract: 319,797. Thrissell Engineering Co., Ltd., (formerly Brecknell, Munro & Rogers, Ltd.), and Dolman, H. J. March 24, 1928. Delivery of articles stored in piles; storage.-A coinfreed vending machine of the kind having a plurality of magazines and an obturator device which prevents the delivery of articles from one or more of the magazines until the articles in another magazine are exhausted, comprises a pair of magazines and a reversible obturator which in one position detains the articles in one magazine and permits the delivery of articles in the second, and, in another position, permits delivery from the first magazine, while detaining the articles in the second. One magazine may be refilled when the obturator has moved to permit delivery from the other. As applied to a machine having a delivery drawer 5, Fig. 1, and two magazines 1, 2 containing articles 3, 4, the obturator 6 is pivoted at 7 between the magazines and is provided with two plates 8, 9 and three fingers 11, 12, 13. When the articles 4 are b3indelivered, the plate 8 projects into the magazine 1 to hold back the articles 3, the plate 8 being held in this position by the pile 4 engaging the plate 9. When the magazine 2 is exhausted, the weight of the. pile 3 reverses the obturator so that delivery is permitted from the magazine 1. The ringers 11, 13 engage a fiaring-mouthed slot, 14 on the drawer, when this-is closed, to relieve the pressure of the plates 8. 9 on the column of articles being delivered. When the drawer is open the pressure of the respective plate 8 or 9 holds back the next article to be delivered which article falls when the drawer is closed again. When both magazines are empty, the obturator swings to a mid-position so that the finger 12 blocks the drawer and closes the coin-slit. As applied to a gravity-operated delivering mechanism, Fig. 5, wherein the articles 33, 34 are delivered by a vaned wheel 35 as described in Specification 285,931, the two shoots 18, 19 for the articles merge into a tapered shoot 20 leading to a single shoot 22. An obturator 23 comprising two sets of arms 24, 25 is pivoted in the channel 20 the arms co-operating with pivoted flaps 28, 29 to hold back the articles in the shoots 18, - 9 respectively. The articles are pressed down by following weights 38 the axles 39 of which finally pass through openings 42 to supporting brackets 44. A cam on the obturator closes the coin-slit when both shoots are empty. Both obturators 6, 23 are symmetrically arranged so that they can be set for delivery from either magazine as desired.

Title: Label feed
Inventor: MACOMBER JAMES KEITH
IPC: B65C9/18
Filed: 1968-02-26
Abstract: 1,260,661. Feeding webs. J. K. MACOMBER. 24 Feb., 1969 [26 Feb., 1968], No. 9089/68. Heading B8R. A device for feeding a ribbon 56 of labels 54 delimited by registration marks in the form of partial cuts 70 and obtaining register for accurately cutting the ribbon along the registration marks comprises a pair of jaws 38, 82 which close to deform the ribbon laterally so that an uncut label 54 assumes a bowed shape with a raised portion 92 at the cut 70. The jaws 38, 82 reciprocate to feed the ribbon forward until the bowed portion 92 abuts the raised edge 159 of a knife blade 156; further forward movement of the jaws 38, 82 causes the ribbon 56 to buckle as at 181 so that the portion 92 is positively located against the blade 156 which is then actuated to cut the ribbon. Thus, each label 54 is severed from the ribbon exactly at the registration mark resulting in the production of accurately cut labels free from such marks. The registration may be effected by the opposite of buckling as in another embodiment in which the ribbon is held taut between a reciprocating cutter and a brake (Figs. 18 to 22, not shown). Thus, the ribbon is coerced by holding means and ribbon engaging means to deform or stress it between said means thereby to obtain register with the cutter. The engaging means may be the jaws 38, 82 as shown in Figs. 1 to 16, or may be partly in the cutting means (259) and in the jaws (240), Fig. 18 (not shown), in the cutting means (459), Fig. 28 (not shown), or a tension plate (660), Fig. 43 (not shown). The holding means may be the knife edge 159, brake elements (220, 320, 421 or 506), Figs. 18, 20, 28, 35 (not shown), or a fixed holding means (620), Fig. 43, not shown. The registration marks may be in the form of perforations rather than cuts.

Abstract: 215,728. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Slepian, J.). May 7, 1923, [Convention date]. Resistance materials.-In the manufacture of an electrical resistance material from a mixture of a conducting and a non-conducting substance. colloidal solutions of alkali metal salts are employed as binders and the mixture is treated with salts, acids or acid salts which will remove some or all of the alkali metal by combination in order to stabilize the resistor when exposed to a humid' atmosphere or subjected to a discharge such as is experienced when used as a lightning arrester- In an example a mixture of lamp black and flint is moistened with a diluted solution of sodium silicate to enable it to be moulded, and is then baked to remove most of the water. The resistoris immersed in a saturated solution of ammonium chloride at lower temperature for from 1 to 2 hours possibly employing a vacuum, and is subsequently 'washed in a stream of water for from 4 to 5 hours. Finally the resistor is dried to remove water and ammonia. The treatment with the alkali removing agent may be repeated several times and the resistor may be further strengthened bv repeatedly impregnating with a solution of the binder followed by baking to remove water- Stannates and aluminates of the alkali metals are also mentioned as suitable binders. As open to inspection under Sect. 91 of the Act the Specification is not limited to the use of colloidal solutions of alkali metal salts. The Specification as accepted is limited in this respect.

Title: Improvements in automatic photographic machines
IPC: G03B27/46
Filed: 1941-07-29
Abstract: 544,872. Automatic photographic machines. BURLEIGH, D. S. July 29, 1941, No. 9612. [Class 98 (i)] An automatic photographic machine in which the negatives are copied to produce positive photographs is provided with two closely adjacent cameras for simultaneously producing two copies of the negative. As shown, the apparatus is assumed to be embodied in an automatic photographic machine as described in Specification 360,210, some of the parts of the mechanism corresponding to those therein described. The duplex camera a is formed by an upwardlydivergent chamber divided by a partition a<SP>1</SP>, on each side of which is one of a pair of closelyadjacent lenses b. The two photographs are printed without any intervening gap. The paper negative to be copied is fed, whilst still wet, on to a grooved platform e by constantly-rotating rolls 148 in a downward extension 147 of the camera. On entering, the negative encounters and depresses a finger c which tilts a pivotallymounted mercury switch 152, so closing the circuit of an electro-magnet which causes a clutch (not shown) to engage and turn a shaft 165 through a single revolution. Interrupted cams 181a on the shaft 165 feed the negative into position with its forward edge against stops d, then allow it to remain stationary, and finally move it into engagement with constantly-rotating delivery rolls 148a, the stops d being withdrawn downwardly during the latter movement by spring arms d<SP>1</SP> on which they are carried and which are normally held up by a cam d<SP>2</SP> on the shaft 165. The switch 152 is restored to its open position by cams c<SP>5</SP> on the shaft during its rotation. The sensitized paper strip is fed into guides grooves 109a in the focal plane of the camera by interrupted cams 111a on a pair of shafts 169, 172 which are geared together and driven by chain and sprocket gearing from the shaft 165. When the strip is in the exposure position, a cam 178 on a shaft 177 driven by chain and sprocket gearing from the shaft 172 tilts a mercury switch h which energizes a lamp 147a to illuminate the negative. Interrupted cams 173 on the shaft 177 then feed the strip into engagement with the entry rolls of the positive developing, fixing and washing tanks. Before the strip is fed by the cams 173 it is severed from the roll by a cutter consisting of a sleeve i having slots through which the strip passes, and within which is a half-round sleeve i<SP>1</SP> which is rocked to shear the strip by means of a cam j which engages an arm i<SP>2</SP> secured to the spindle.

Title: Typewriter having a variable step-by-step spacing movement
IPC: B41J19/58
Filed: 1949-04-11
Abstract: 661,127. Typewriters. TORPEDO WERKE AKT.-GES. FAHRRADER U. SCHREIBMASCHINEN. April 11, 1949 [April 13, 1948], No. 9809/49. Class 100 (iv). In a feed arrangement for the paper carriage of typewriters, comprising an escapement lock having a fixed pawl and a loose pawl for adjusting a ratchet wheel to perform a spacing operation, a back-space pawl for the ratchet wheel, and an adjustable abutment for the loose pawl, for varying the length of the spring movements, the loose pawl and the back-space pawl are each pivotally mounted on a pin constituting one element of a pin-and-slot connection which permits movements of the pawl relatively to the ratchet wheel to ensure a substantially constant depth of engagement of the pawl with the ratchet wheel throughout the spacing movement. On the escapement lock place 1 are mounted the fixed pawl and the loose pawl 3, the latter being mounted on a pin 5 and guided thereon by a curved slot 22. On release from .the ratchet wheel 4, the pawl 3 swings anticlockwise and is also moved to the left by a spring 6, and thus towards the ratchet wheel so as to make firm engagement therewith when racked into operative position by the plate 1. The amount of movement of the pawl, and hence the spacing movement of the ratchet wheel when it swings the pawl back until its nose 20 bears against a fixed abutment 21, is controlled by the position of the adjustable abutment 7 which limits the leftward movement of the pawl. The abutment 7 is rocked for longer spacing by means of a link system, including a spring 10, actuated by a comb bar pivotally mounted below the key levers and having teeth cooperating with the type levers of characters requiring longer spacing and with the shift-key and shift-lock levers, the amount of swing of the abutment 7 varying according to the disposition of the comb teeth. In order to reduce the amount of swing of the pawl 3 to the left of the vertical plane through the axis of the ratchet wheel, the abutment 21 is arranged so that the operative face 23 of the pawl lies slightly to the right of the plane in the initial position. In order to avoid the jamming in the ratchet wheel of the finger of the back-space lever when long spacing is used, the back-space lever is also guided on its mounting pin by means of a slot and is spring-urged towards the ratchet wheel so that the latter can move the lever against the spring action as soon as the finger encounters the bottom of a tooth gap.

Abstract: 527,771. Magnetic separators. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 29. 1939, No. 9844. Convention date, April 1, 1938. [Class 72] In a magnetic separator for treating a fluid containing magnetizable particles in which a magnetic field, preferably generated by a permanent magnet, is set up in gaps which lie in the fluid, but out of the stream of the flow and in which the particles magnetically extracted are collected and retained in such gaps, the passage through which the fluid is conducted past such gaps has a transverse section which is so narrow, preferably of the order of a few mm., that in conjunction with the required speed of flow and viscosity of the fluid, the strength of the magnetic field is effective throughout the whole transverse section of the passage. Mounted in a housing 1 on a rod 4 of non-magnetic material is a permanent magnet 8 held between pole plates 6, 9 also clamped on the rod, these plates being provided with apertures 7, 10 respectively. Between the plates 6, 9 is also clamped a hollow cylindrical member 11 of non-magnetic material, such as aluminium, and in the space between the wall 13 of the member and the inner wall 12 of the housing 1 are mounted pole pieces 14. semi-circular, connected together by strips 15 to form a unit which has air gaps 16 and provides passages 17, 18. The fluid to be treated is fed into the housing 1 by a pipe 2 and flows onto the plate 9 passing over the edge of the plate through the apertures down the passages 17, 18. Magnetic particles in the fluid are attracted into, and retained in, the gaps 16 and the purified fluid passes into the space below the plate 7 and out through a pipe 3.
