Title: Improvements in indicator devices for cash registers and like accounting machines
IPC: G06C11/02
Filed: 1948-12-18
Abstract: 668,841. Cash registers. KOOPERATIVA FORBUNDET, FORENING, U. P. A. Dec. 18, 1948 [Dec. 31, 1947], No. 32783/48. Class 106 (i). An indicator drum of a cash register, for showing which of a series of totalizers is selected, has one or more additional indicating positions for alternatively showing the kind of operation for which the machine is set. Thus, the drum 5 has five indicating positions and is associated with a total-taking key T, in an operation control key-bank, as well as a bank of four salesman or transaction keys A-E. The stems of the keys A-E limit the upward movement of a differential totalizer selection rack 2, the return movement of which is transferred by a pinion 4 to a rack 3 which correspondingly adjusts the indicator drum 5 to one of its first four positions. Depression of the total key T, through a key-bank slide 6 and a connecting rock-shaft 9, projects a slide 11 into a notch 14 in the locking slide 1 of the keys A-E so that they cannot be actuated. The differential slide 2 then makes a full upward movement limited by a stop pin 16 and the indicator drum is moved to its fifth position. In a modification (not shown) having three totaltaking keys and the drum 5 correspondingly three additional indicating positions, the totaltaking keys actuate the slides 6 and 11 differentially, and the ends of the slide 11 and rack 2 are formed with co-operating stepped abutments so that the drum 5 is adjusted according to which total-taking key is depressed.

Abstract: 329,631. Wallace, R., and British Automatic Totalisator, Ltd. Feb. 19, 1929. Totalizators. - Electric signalling apparatus particularly applicable to totalizators include competitor and win and place keys at each issuing station, stations of different denominational value, and horse collectors rotating continuously over contacts in circuit with keys allotted to the respective horse at each station. In the lay-out shown in Fig. 1, six machines 1 for issuing 2/- tickets and three machines 2 for ú1 tickets are provided with a number of horse keys of which one only, 3, is illustrated. This key in each of the 2/- machines is capable of closing a circuit to either of the sets of contacts 6, 8 of collectors 7, . according as the win key 12 or place key 13 is depressed. The lines from the keys, via key 12 for instance, proceed to tell-tale meters 10 and thence through the plug-in switch 39 to the contacts 6 of the collector 7, the arm of which is connected with the source through magnet windings 22, 23 controlling the counting escapements of the horse and grand total counters. A similar arrangement of circuits is provided for totalling the place bets (collector 9) and the win and place bets for the ú1 tickets (collectors 16, 17. In order to transfer from one denomination (2/-) to the other (ú1) the counter of the collector (7) on the receipt of each tenth impulse swings over a switch 48 to cut out the totals counter magnet 27 and complete a line for marking a contact 49 on the ú1 collector bank. The ticket printing and issuing motors such as 30 are put in circuit by the completion of circuit through the respective marked contacts, a relay 34 operating a switch 46 for this purpose. A construction of collector suitable for receiving bets on one horse is shown in Pigs. 2 and 3. Six arms 54 - - 59, secured to a constantly driven shaft 53, sweep over the banks of contacts and close circuit intermittently to magnets 62 operating, through pawls 63, to release contact drums 64 driven frictionally from shaft 53 and controlling, through switches 66, the respective public indicators which may be as described in Specification 326,637. The drums, which may be allocated as to three to the hundreds tens and units of win bets and as to the other three similarly to the place bets, may carry numerals to exhibit the totals to the operator through windows 67. To prevent mutual interference of the impulse circuits, the contacts may be connected up so that in any one position of the shaft 53 the contacts engaged by the arms appertain to the keys of only one issuing- machine. Specifications 289,901, 294,181, and 323,056 also are referred to.

Title: Improvements in or relating to the hydration of olefines
IPC: C07C29/04
Filed: 1938-11-14
Abstract: 511,247. Hydrating olefines USINES DE MELLE. Nov. 14; 1938, No. 33096. Convention date, Nov. 17, 1937. Drawings to Specification. [Class 2 (iii)] Olefines are hydrated directly to alcohols by passing the gaseous olefine, or gas containing olefine, through a battery of vessels through which passes in counter current to the gas a warm acid hydrating solution, the concentration of which is below that giving rise to secondary reactions, and the gas being emulsified in the acid in each vessel, preferably by centrifugal means. The hydrating solution containing the alcohol is passed from the last vessel to a tower where a hot inert gas or superheated -steam is blown through it and the gas leaving the tower is cooled to condense the alcohol, whiles the hydrating solution is made up to its initial strength and returned to the process. The vessels may be separate closed vessels connected by gas and liquid, pipes; or compartments in the same closed tank connected by gas pipes and overflows for the liquid. Examples are given of the production of ethyl alcohol from a mixture of ethylene and ethane, and isopropyl alcohol from a mixture of propylene and propane, using a pressure, slightly above atmospheric. Several groups of tanks may be used coupled in various ways. The hydrating solution may be sulphuric acid of 50-80 per cent., containing sulphates or bisulphates in solution and may b.e modified by adding sulphonic acids such as benzene sulphonic acid, as well as certain catalysts such as salts of silver, copper or mercury.

Filed: 1972-07-14
Abstract: 1381151 Gear crimping AKZO NV 14 July 1972 [17 July 1971] 33149/72 Heading D1F A yarn 1 is crimped and partially drawn by a zig-zag passage between the meshing projections of at least two co-operating rotatable crimping gears that are supported in air or other bearings of such low friction that they are rotated by the passage of the yarn. Preferably there are two gears 9, 10, although in Fig. 6 (not shown) a third gear (44) is disclosed co-operating with and coplanar with 9 and 10.  Each of the gears may comprise a toothed ring 48 with the distance between the-bottom of a tooth gap and the inside of the ring not more than 10 mm. At opposite sides of the ring are extensions 17, 18, of smaller diameter. The ring is supported with some radial and axial clearance 19, 20 by a hub 21 with removable collars 22, 23, the hub being connected via channel 31 and bore 30 to a compressed air supply. The axis of rotation of gears 9, 10 may be eccentric to the axis of core 26 to facilitate adjusting the separation of the gears. In the embodiment of (Fig. 7, not shown) each gear has a pair of sapphires (50) which support the gear in rotatable contact with hardened steel cones (51). As shown in Fig. 1 the yarn is drawn from package 2 by rolls 3, 4, heated by heated draw pin 8 (and/or by a heated plate) and drawn through gears 9, 10 by roll 6, whose circumferential speed is 3 to 4 times that of feed rolls 3, 4. Preferably a drawing of 1.3 to 1.8 occurs between the crimping gears 9, 10. The drawn erimpted yarn 11 may be passed through eyelet 12 and deposited by traveller 16 on vertically rotating package 13. Alternatively the yarn may be passed over a separator roll (7, Fig. 3, not shown) a draw roll (6) and then passes over an extension (17) of gear 9 or over gear 9 itself. In the embodiment of Fig. 4 (not shown) molten nylon, polyester, polypropylene or polyacrylonitrile is drawn and crimpted as in Fig. 1, the yarn passed through an air jet (36) and wound on a package (39) rotating about a horizontal axis. In the modification of Fig. 5 (not shown) the drawn, crimpted yarn passes around a spring-mounted roll (54) and an extension (17) of gear 9 before passing drawing roll 7, thereby minimising variation in tension in the yarn during crimping.

Title: Improvements in or relating to vacuum or low-pressure gas or vapour apparatus for electric discharges
IPC: H02M1/04
Filed: 1933-11-27
Abstract: 420,724. Converting. ELIN AKT.- GES. FUR ELEKTRISCHE INDUSTRIE, 1, Volksgartenstrasse, Vienna. Nov. 27, 1933, Nos. 33218 and 33219. Convention dates, Nov. 26, 1932 and April 8, 1933. [Class 38 (ii)] Auxiliary electrodes are arranged adjacent the anodes and are fed with a variable intermittent voltage which consists of only the steeply inclined parts of an alternating voltage superimposed on a negative voltage. In one form the grid has applied to it a high amplitude alternating voltage and a negative bias, and a spark gap short-circuits the alternating voltage before it has risen to the top of the curve, giving a grid voltage curve 1, Fig. 2. In a modification, an additional negatively biassed grid is inserted between the first grid and the anode, at the edge of the anodic dark space. In the arrangement shown in Fig. 5, a spark gap Pf breaks down when the grid voltage has risen to a predetermined value and a series resistance R limits the current flow through it. In a modification the inductive resistance of the transformer winding T may be increased and the resistance R omitted. Two valves in parallel, having equal or different breakdown voltages may be used instead of a spark-gap. The grid voltage may be phasedisplaced by a rotating controller or, as shown in Fig. 8 wherein a five-core transformer for a six-phase system is shown, by passing a continuous current through windings on the first and fifth cores and regulating the magnetization currents by a control switch SR. A condenser system C, so arranged that without presaturation it delivers a leading current through the resistances W and with maximum saturation a lagging current may be added. The steepness of the control voltage curve may be increased by using a higher harmonic, for example the third. In switching off, either in normal operation or on short circuit or backarcing, the permanent negative voltage is allowed to remain, and hand or automatic operation switches off the alternating voltage source, preferably on the primary side.
