Title: Improvements in or relating to batching devices for coins and other disc-shaped articles
Inventor: WILCOX KENNETH
IPC: G07D9/06
Filed: 1968-05-30
Abstract: 1275411 Batching coins SABLOC AUTOMATIC SYSTEMS Ltd 23 May 1969 [30 May 1968] 25869/68 Heading G4X  A batching device for discs, e.g. coins, comprises means for supporting a row of discs in edge to edge relation, means for turning each disc so that it lies in a different plane to those in which the other discs lie, all the different planes being parallel, and means for assembling the turned discs into face to face relationship. As shown, seven coins, from a supply 38, Fig. 2, roll along the space between two elongated guides 18, 19 until the centre of each coin is above a corresponding channel 14 formed in a receiver 11. Each guide 18, 19 comprises two channel-section members, Fig. 4, spring-biased apart, the bottom flanges of the outer members 19 being normally spaced by less than the thickness of a coin to form a platform along which the coins roll in the initial closely spaced position of the guides, Fig. 3 (not shown). When the coins have been stopped above their respective channels 14, a solenoid-operated restraining linkage 33-37 is operated to allow the guides to move apart under the influence of springs 31. The coins fall on to the upper bevelled edges of the channels 14 and are thus turned until aligned with their respective channels, into and along which they then roll to the left hand end of receiver 11 as shown in Fig. 2. In a modification, Figs. 7 and 8 (not shown), fourteen channels 14 are provided. In a second embodiment, Figs. 9-11 (not shown), the guides are formed by a row of rotatable members, each formed with a diametrical slot. The slots are initially aligned to form a coin channel. When a coin is located in the slot of each rotatable member, the members are rotated to positively position the coins in their different parallel planes, before dropping the coins into their respective channels in the receiver.

Title: Dehydration of polymerization diluent
IPC: C08F6/04
Filed: 1960-07-26
Abstract: A polymerization process in which a C2-C6 alpha olefin is polymerized in the presence of a catalyst containing a partially reduced, heavy transition metal halide and an aluminium alkyl compound in a hydrocarbon solvent higher boiling than methanol, and in which methanol is added to the reaction system to precipitate polymer product which is then separated from the methanol-solvent-water mixture is improved by feeding the mixture as a vapour to a fractionation storer, fractionating so as to withdraw a water rich sidestream of methanol and hydrocarbon solvent from the tower above the point of entry of the feed, cooling this sidestream to a maximum temperature of 100 DEG F., passing this cooled sidestream through a desiccant to remove water therefrom, recycling the residual sidestream fraction back to the tower, taking overhead from the tower a water-free methanol and taking as bottoms a water-free hydrocarbon solvent.  Both the methanol stream and the water-free hydrocarbon solvent may be recycled to the polymerization stage.  Specified alpha-olefins are ethylene, propylene, butene-1 and hexene-1. Specified solvents are n-heptane, benzene and, preferably, xylene. Calcium sulphate is the specified desiccant.  Apparatus for carrying out the process is described.  Specification 810,023 is referred to.

Title: Electronic circuits for the generation of special effects in symbols displayed on a picture tube
IPC: H04N7/18
Filed: 1975-06-20
Abstract: 1500168 Cathode-ray-tube displays INDUSTRIE A ZANUSSI SpA 20 June 1975 [23 July 1974] 26403/75 Heading H4T In a television games system a circuit which operates to cause reversal of the direction of horizontal motion of a "ball" symbol when it comes into contact with either of two "bat" symbols (e.g. table-tennis) and to cause reversal of the direction of the vertical component of ball motion when it comes into contact with either of an upper or lower boundary "wall" is arranged, also, to cause reversal of the vertical component of ball motion when the ball comes into contact with an edge portion of either bat symbol, i.e. a "spin" effect is produced. As described, pulse generators 42, 7 and 8 (Fig. 1), generate the respective signals shown in Figs. 4a, 4b and 4c which produce the respective displays of the "ball" symbol 4 (Figs. 2 and 3) and the "bat" symbols 7' and 8' and further pulse generators 15, 16 produce signals, generally similar to those of Figs. 4b and 4c which produce the respective "side" boundary wall symbols 15' and 16'. The bat symbols may be moved in the vertical direction by means not shown. In operation "contact" of the ball with either of the wall symbols (i.e. time coincidence of the respective signals) is detected by the logic circuit including NAND gates 17 to 20 to produce an output signal which is supplied to a circuit 21 acting via a phase control circuit 6 to reverse the vertical component of motion of the ball as shown in Fig. 2 in respect of the path of the ball between bat 8<SP>1</SP>, wall 15<SP>1</SP> and bat 7'. In a similar manner "contact" of the ball with either of the bats 7<SP>1</SP> or 8<SP>1</SP> produces, via a similar logic circuit including NAND gates 10 to 13, a signal which acts via a circuit and phase control circuit 5 to reverse the horizontal component of motion of the ball. Additionally, the output of NAND gates 12 and 13 are differentiated in the respective R.C. circuits 30, 28 and 31, 29 to produce signals the positive portions of which produce a sound via loud-speaker 41 which is characteristic of that produced by a bat and ball contact. In accordance with the invention, generators 26 and 27 produce the respective pulse signals of Figs. 4l and 4m which effectively gate out the "top edge" (top half) portion of the bat symbol waveforms of Figs. 4b and 4c in NAND gates 24 and 25 and via further NAND gates 23 and 22 coincidence of the ball and the "top edge" of either bat produces a signal via NAND gates 19 and 20 which also causes a reversal of the vertical component of motion of the ball via the circuit 21 and phase control circuit 6 as shown in Fig. 4 in respect of the path 44 of the ball 4 between boundary wall 15' and the top edge 7" of bat 7' and its reversed path 45.

Title: Improvements in or relating to automatic electric circuit breakers
IPC: H01H71/16
Filed: 1955-09-15
Abstract: 784,556. Automatic circuit - - breakers. ALLIS - CHALMERS MANUFACTURING CO. Sept. 15, 1955 [Sept. 22, 1954], No. 26484/55. Class 38 (5). An A.C. circuit-breaker has a tripping device comprising a core 42, a coil 21, a tripping armature 46, a latch 54, 56 to hold the armature against movement, a heater 62 energized in proportion to the current in the coil 21, a bimetallic element 61 which is heated by the heater to release the latch and tripping means (not shown) actuated by the armature. In Fig. 9 an armature-like member 47 is pivoted on a shaft 49 but is adjustably fixed by a bolt 64. The member 47 carries a coil 52 inductively coupled to the coil 21 and connected to the heater 62. Under prolonged overload conditions, the flux produced by the coil 21 in the core 42 is sufficient to attract the armature 46 but it is latched by the latch. The current induced in the coil 52 energizes the heater 62 and the bimetallic element is heated. One end of the coiled bimetal is fixed to the latch cam 54, Fig. 5, and the other end is fixed to a shaft 60 which may be turned through worm and wheel gearing 71, 68 to set the initial position of the latch cam 54. Thus, when the bimetal is sufficiently heated, it turns the latch cam 54 clear of a roller 58 carried by the armature 46 which is now attracted and through a striker 72 causes the tripping of the circuitbreaker. Should a high excess current condition occur, a further armature 48 is immediately attracted to produce tripping of the circuitbreaker without delay. The general arrangement of the circuit-breaker contact assembly, tripping mechanism and closing mechanism is that described in Specification 775,940.

Title: Boolean expression verifying apparatus
Inventor: CLARK JOHN MASON
IPC: G11C15/06
Filed: 1963-07-06
Abstract: 1,010,638. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 2, 1964 [July 6, 1963], No. 26854/63. Heading G4C. In apparatus for verifying a Boolean expression having a plurality of items of which each is joined to the next item by one of several connectors, a history signal is produced in accordance with each item-connector pair and is combined with signals representing the next item-corimector pair to produce another history signal, history signals being thus successively generated until the whole of the expression has been verified. In searching personnel or other records in a magnetic tape or disc store 10 (Fig. 1), record words are read into a buffer store 12 in turn, for comparison with required items an item at a time. The result of each item-comparison (GOOD or BAD) is supplied on lines 32 to a verifier block 28 (details in Fig. 2) which also receives an indication of the following connector on lines 30. These signals, together with history signals on lines 42 from a history store 36 result in the setting of one of a number of magnetic cores 51 to 63 in verifier 28. A reset signal then applied to all the cores on line 44 results in history signals being supplied to history store 36 on lines 34, and control information and indication of misses to control logic 16 on lines 38, 40 respectively. The possible connectors are AND, OR, BRACKET and SPECIAL BRACKET, and the possible history signals are OKAY, HUNT OR and HUNT BRACKET. The control information consists of a command to supply either the next item and connector or just the next connector. In the latter case, a GOOD indication is supplied from the compare unit on lines 32. If the history signal on lines 34 from verifier 28 is HUNT OR or HUNT BRACKET, only the next connector will be supplied, otherwise both connector and item will be supplied. The (two) possible indications of misses on lines 40 are those consequent upon detection of BRACKET and SPECIAL BRACKET respectively. The former implies that the Boolean expression in buffer 12 definitely is invalid (i.e. does not satisfy the requirements searched for) but a predetermined number (specified on line 24, Fig. 1) of SPECIAL BRACKET misses are permissible before invalidity can be concluded. The other inputs 20, 22 to control logic 16 are search mode instructions and data location information (no details). The item-comparison may be to find out whether or not actual item is equal, unequal, high or low with reference to the desired item.
