Title: Apparatus for issuing revised betting tickets
IPC: G06Q50/00
Filed: 1976-09-03
Abstract: 1530935 Selective printing FUJITSU Ltd & JAPAN RACING ASSOCIATION 3 Sept 1976 [13 Sept 1975] 36527/76 Heading B6F [Also in Division G4] Apparatus for issuing tickets is also arranged to receive an already issued ticket and to issue a new ticket incorporating desired changes of the data borne by the received ticket. In operation, the data on the received ticket is read and stored, the stored data is displayed, instructions to erase part of the data and/or to add further data are set up and then, upon generation of a print ticket signal, the new ticket is issued bearing the stored data with the exception of the parts to be erased and/or with the addition of the further data. As described, each ticket is a betting ticket and bears fixed information (e.g. date, name of racecourse and variable information in the form of several bets). Both types of information are both printed on and magnetically encoded upon the ticket. To erase a bet, the machine operator either punches a hole in the ticket alongside the bet prior to feeding the ticket in the machine, or feeds the ticket into the machine and depresses a button alongside the relevant bet on the display of the ticket data, or operates the machine to move an arrow until it aligns with the relevant displayed bet and then depresses an "erase" button. A bet to be added is keyed in. The stored data, together with the erase and add instructions, is then passed to a computer, which updates its betting data store and calculates the stake value of the new ticket and generates a "print new ticket" signal. The new ticket bears the fixed information of the old ticket and the revised variable information. The ticket issuing mechanism includes a cutter to sever a ticket length from a blank web, first and second type wheels for the fixed and variable information respectively and magnetic write and read heads, Fig. 6 (not shown). Preferred layouts for the operating and display panels are described, Figs. 3, 9 and 11 (not shown). The operation is described with reference to circuit block diagrams, Figs. 4 and 5 (not shown).

Title: Electric arc welding
Inventor: BRITTAINE LAWRENCE JOSEPH
IPC: B23K9/173
Filed: 1958-11-13
Abstract: 876,379. Welding by fusion. BRITISH OXYGEN CO. Ltd. Nov. 2, 1959 [Nov. 13, 1958], No. 36574/58. Class 83 (4). In gas shielded metal arc welding using an electrode of readily oxidized metal, e.g. aluminium, magnesium and their alloys, in a shield of non-oxidizing gas, in which the arc is initiated by feeding the electrode into contact with the workpiece, appreciable oxidation of the electrode tip is caused to occur at the end of the welding period whilst the tip is so hot that further cooling produces a ridged surface on the tip. The process is particularly applicable to spot welding, the ridged surface facilitating striking of the arc. The oxidation is induced by focusing on to the tip of the electrode 4, heat from the weld pool by the use of a reflector 6 attached to the contact tube 5. In a modification, at the end of the welding period, an oxidizing gas, e.g. oxygen, air or carbon dioxide, is directed on to the electrode tip. The gas may be directed through the contact tube, a pipe coaxial with the contact tube or a separate pipe. Specification 839,661 is referred to.

As shown in Figs. 2 to 4 an accumulating conveyer comprises a number of rollers 14, each with a sprocket 15 at one end over a rail member 20 with an upper support surface 22 and a lower support surface 23 for a chain 24 with riders 42. When on the upper support surface 22 the chain 24 drivingly engages the sprockets 15; when on the lower support surface the chain 24 is out of driving contact with the sprockets 15. The chain 24 is guided from one support surface to the other by ramps 30, each of which is controlled by a sensing roller 39 by means of a lever 38 pivoted at 41 and connected to the ramp 30 by a rod 36. Both the ramp 30 and the upper support surface 22 have a gap large enough for the main body of the chain 24 to pass through, but small enough to support the chain by the riders 42. In Fig. 2 the chain (not shown) moves from right to left, thus driving the rollers clockwise to move articles (not shown) from left to right. The right-hand sensing roller 39 is shown depressed by an article, thus elevating the associated ramp 30 so that the chain 24 passes from the upper support surface 22 under the ramp 30 to the lower support surface 23, Fig. 5 (not shown), disengaging the drive to the rollers to the left of the ramp and halting any articles on that section of the conveyer 10. When the article has cleared the sensing roller 39 a spring 40 returns the ramp 30 to its lowered position so that the chain 24 is guided to the upper support surface 22 (Fig. 4) and the drive to the rollers 14 re-engaged. Figs. 7, 9 show an accumulating conveyer 60 wherein articles (not shown) are supported on wheels 63 and propelled by engagement with a narrow V-belt 24a having laterally projecting pins 64 arranged to carry the belt on an upper support surface 22 in driving engagement with the articles.

An optical projection screen for use with an optical comparator is supported by two belt-andpulley systems so arranged that the screen moves in one linear direction by the advance of one belt, and in an orthogonal direction by advance of the other belt, in the plane of the screen. As shown, a system of six pulleys 7 defines a double U-shaped path for a belt 9 tensioned by spring loading 20 on pulley 7B, and capable of advance in either sense by manual rotation of a control pulley 7A. The frame 3 of screen 1 is fixed at 27 and 28 to portions of the belt in opposite arms of the U that move in the same direction. Frame 3 is fixed at two other points to a second identical belt-andpulley system lying behind and parallel with the first and rotated relatively to the latter by a quarter turn. The second belt can also be manually advanced for adjustment transverse to the first direction of adjustment. As shown in Fig. 4 a control pulley 7A is rotatable through one revolution on a fixed spindle 12 by means of an external control knob 13 rigidly connected to the pulley by a sleeve 11. On the inner surface of the latter bear fibre braking plugs 16 seated in radial bores 15 of the fixed spindle 12. The bores 15 connect with an axial bore 14 in which a screw 17 can be advanced or retracted to vary the thrust, and hence the braking action, of its conical tip against the bottoms of the plugs 16. These prevent slip of the pulleys under the weight of the screen, while allowing manual rotation. Relative slip between the belts and pulleys is reduced by winding the belt at least once round each pulley. A flange 6 of frame 3 can be clamped by screws extending through an external casing to lock the screen in position.

Title: Improvements in automatic stop-motion mechanism for sheetfeeding machines
IPC: B65H7/20
Filed: 1929-12-16
Abstract: 333,487. Spiess, G. Dec. 20, 1928, [Convention date]. Stopping-arrangements. - An automatic stop-motion for sheet-feeding machines comprises two movable spring-controlled feelers 23, Fig. 6, in the path of sheets moving over a pivoted feed-board B and adapted to engage notched lever arms 20 on a shaft 19 which is normally oscillated by means of an adjustable cam 5 secured to a groove in a disc 3 on a cam shaft 2. The cam 5 actuates a lever 9, 10 connected by a link 12, lever 15, rod 16 to an arm 17 on the shaft 19, which normally causes the arms 20 to oscillate in an opening 21 on the under side of the board B. If either of the feelers 23 is unacted upon by a portion of a sheet, the shaft 19 is prevented from returning under the action of its spring, and the lever 9 is prevented from moving towards the shaft 2 as it does in the normal operation of the machine. During this normal motion, co-operating wedge surfaces on the lever 9, and on a lever 32 freely mounted on the pivot 8 of lever 9, cause the lever 32 to move axially against the action of a spring 31, Fig. 4, into the path of a cam 6, but the spring 31 returns the lever 32 before the cam rotates it. If, however, the lever 9 is held from its normal action by either of the feelers 23, the lever 32 is held so that the cam 6 engages a roller 34 on it, and a rod 35 transmits the motion of the lever 32 to a stop-motion device. The lever 15 and the feelers are so arranged that they can move with the feed-board when it is tilted to the dotted line position Fig. 1.
