Title: Improvements in and relating to coin-freed mechanism
IPC: G07F5/08
Filed: 1933-12-21
Abstract: 425,252. Coin-freed apparatus. PYE, J. R., 164, Eccleshall Road, Hook Gate, near Market Drayton, Shropshire. Dec. 21, 1933, No. 35925. [Class 27] Coin action, mechanical-connection and multiple-coin.-Coin-freed mechanism having a number of shoots for the passage of coins of different denominations is provided with rocking members controlling the paths of the coins in each shoot and rocked by the passage of a coin down any one of the shoots, the arrange. ment being such that a succession of coins to the required value clears a path for the final coin of the series to proceed to the releasing mechanism irrespective of the order in which the coins are inserted. As applied to a goods vending machine selling threepenny packets of goods and taking pennies and half-pennies in any order, half-pennies are inserted in a shoot 10, Figs. 1 and 2, and pennies in a parallel shoot 21. The first, third, and fifth half-pennies are diverted to a branch shoot 11 by a starshaped rocker 13, 14, 15 which controls the shoot 10 and which is reset by the passage of the second, fourth and sixth half-pennies, these coins then passing down shoot 12. The second halfpenny is diverted to a shoot 22 leading to the till by a double-rocker having a pair of arms 17, 18 controlling the halfpenny shoot and a similar pair 19, 20 controlling a junction in the penny shoot. The double-rocker is also moved to the position shown in dotted lines so that the fourth half-penny can pass along a shoot 23 to a junction controlled by a double three-armed rocker 25 ... 30 having a set of arms in the penny and half-penny shoots respectively. The fourth half-penny is diverted to the till along a branch 44 and clears a path for the sixth half-penny along a shoot 32 to the releasing mechanism, this coin in its passage resetting the rocker 25 .. 30. If three pennies are used, the first two are diverted by the double-rockers, which clear a path for the third to pass to the releasing mechanism, this coin also resetting the double-rocker 25 .. 30. Since each penny performs the same operation as every second half-penny, the sum of threepence may be made up of half-pennies and pennies inserted in any order. The last halfpenny actuating the releasing-mechanism passes to a slot 35 in a slide 34 forming part of the delivery drawer of the machine. It rests on a ledge 36 and projects sufficiently to raise a pawl 40 normally preventing withdrawal of the slide. The last penny acts in a similar way to release the delivery drawer. When the slide 34 is pulled out, an incline 41 thereon acts on a roller 42 to raise a rod 43 and reset the first double-rocker 17 ... 20 to its initial position. A third shoot for threepenny pieces is also provided.

Title: A magnetic amplifier
IPC: H03F9/04
Filed: 1963-09-12
Abstract: 1,030,017. Magnetic amplifiers. NIHON GENSHIRYOKU KENKYU SHO. Sept. 12, 1963 [Sept. 22, 1962], No. 35959/63. Heading H3B. A single core magnetic amplifier of the resetting type provides a push - pull output corresponding in polarity to that of the input signal. The single core I has a rectangular hysteresis loop, and the degree of flux setting is determined by a D.C. energized bias winding Nc in association with a positive or a negative signal Iin in a signal winding Nin. Two gate windings N 1 , N 2  are provided, winding N 1  being energized through a diode D 1  during alternate half-cycles of an A.C. source, e.g. to reset the flux to saturation, while winding N 2  is energized by transformer action during the timer when the core is unsaturated. The windings N 1 , N 2  are connected to respective resistors R 1 , R 2  across which the push-pull output V 0  is developed, R 2  being of the order of 5R 1  in value when windings N 1  and N 2  have equal turns. During each resetting period the source polarity is as shown, and while the flux is changing voltages e 1  and e 2  are established across windings N 1  and N 2  respectively which produce corresponding potentials V 1  and V 2  across R 1  and R 2 . The resetting period is shown in Fig. 3 as O to #f, and in this period voltage V 2  predominates since the voltage drop e 1  in winding N 1  gives a resultant V 1  potential of e s -e 1 . When the core saturates at #f, V 2  falls to zero and V 1  becomes equal to e s . In the Figures, B and C show the variation of V 1 , and A gives the resultant voltage V 2  which falls to zero at #f. As this angle is variable by the bias, then in the absence of a signal the bias is adjusted to be such that the average of voltage V 1  is equal to the average of voltage V 2 . The average push-pull output voltage V 0  is then zero. This condition is obtained when equality exists between A resultant average output voltage of appropriate polarity is then obtained when a signal Iin is applied.

[Also in Group XX] A navigational aid comprises a distance-measuring device or odometer and an analyser which is direction-sensitive and which produces upon an indicator or indicators a measure of the direction and distance to be travelled to reach a preselected destinationpoint. Counters for indicating the distance to be travelled by a vehicle, resolved in two directions, are driven by the shafts of two wheels C<SP>1</SP>, C" which are driven by wheels A<SP>1</SP>, All driven by cones Q<SP>1</SP>, Q<SP>11</SP> in accordance with the speed of the vehicle and positioned radially of the wheels A<SP>1</SP>, All in accordance with the heading of the vehicle. In the case of a road vehicle, the positioning mechanism may comprise a shaft X driven in accordance with the speed of the vehicle and positioned by the steering-wheel so that one or other of the wheels El, Ell thereon or neither engages the inner discs of two pairs of inner discs D<SP>1</SP>, D<SP>11</SP>, the outer discs carrying pins P<SP>1</SP>, P<SP>11</SP> for positioning slides G<SP>1</SP>, G<SP>11</SP> which carry the wheels C<SP>1</SP>, C<SP>11</SP>. Thus when the vehicle is driven straight, neither wheel El, E<SP>11</SP> engages the discs D<SP>1</SP>, D<SP>11</SP>, but when the steering- wheel is turned one or the other wheel El, Ell drives the discs D<SP>1</SP>, D<SP>11</SP> in opposite directions and, through pins P<SP>1</SP>, P<SP>11</SP>, shifts the wheels C<SP>1</SP>, C<SP>11</SP> to change the ratio of transmission from the wheels A<SP>1</SP>, All appropriately for the new heading. Screws W<SP>1</SP>, W<SP>11</SP> are provided for adjusting the cones Q<SP>1</SP>, Q<SP>11</SP> longitudinally to correct for variation of incline. The directional axes may be at right-angles, the axes may be chosen so that their bisector coincides with the line joining the origin and the desired destination, the counters may be preset to required distances so that their readings are reduced to zero upon arrival at the destination, the readings of the counters may be indicated by two pointers moving over a dial toward a datum mark as the destination is approached or a single pointer can be caused to move to right or left of a datum mark to indicate an error in direction from the shortest path or a desired correction, while the distance could be represented by a separate pointer or a conventional odometer display. The variation of the ratio of the variable gears according to the heading of the vehicle may be determined by using a compass or gyro, such a method being essential in the case of ships and aeroplanes. In the case of a ship, distance may be measured by a conventional form of log, whilst in the case of an aeroplane, a computer may correlate indications of airspeed with time.

Abstract: 1,190,439. Valves; pipe joints. REYNOLDS METAL CO. 11 Aug., 1967 [11 Aug., 1966], No. 37081/67. Headings F2G and F2V. A drip less tap 14 for a beer container 11 has a frusto-conical surface 38 formed adjacent the outlet with which a frusto-conical valve member 47 co-operates to control the flow. When seated the end surface of the valve member is coplanar with the outlet end surface 42, thus leaving no space for liquid to remain externally of the closed valve which can subsequently drip. The valve is actuated by a handle 72 pivoted to the upper end of the valve stem 48 and having rounded flange edges 79 which contact the housing top on pulling the handle to move the valve upwards against the bias of spring 69. The housing top part 20 is a snap fit on to the housing part 19 and sealingly traps the end of a rubber or plastics sleeve surrounding the valve member and stem. Foaming is reduced by having the syphon tube 16 connected by a push fit to a conical bored tube 18 joined to the housing part 19, the passage 22 through which meets the chamber 25 at right angles. The frusto conical surfaces 38, 43 are disposed at 12 degrees relative to the longitudinal axis of the outlet which in use is disposed at 10 degrees relative to a vertical axis. The frustoconical surface 35 is disposed at 4 degrees relative to the longitudinal axis of the tube 18. The housing part 19 is secured in the opening of the container 11 by a bayonet fitting. In modifications the flanges of the handle are disposed between housing projections to prevent handle twist and the flanges and projections may have aligned slots into which temporary locking bars are inserted. Also the resilient sleeve surrounding the valve member and stem may be so shaped between the stem and the housing that it provides a closing bias to the valve, when the spring 69 may be dispensed with. An external spring acting between the top of the valve stem and the housing top may be provided to assist the bias of the resilient sleeve. Further the syphon tube has a cup-shaped portion 97, Fig. 6, which has an annular bead 98 snap fitted into a recess 95 of housing part 84.

Abstract: 863,362. Carburetters. GRAY, J. A. July 30, 1957 [Dec. 5, 1956], No. 37113/56. Class 7(3). A carburetter comprises a throttle slide 14a jet tube 15, a plunger or needle valve 22 or sleeve movable with the throttle slide for progressively closing and opening the outlet of the jet tube, a pilot jet 31 and an air inlet passage 35 in communication with the pilot jet and atmosphere and extending through the throttle slide. As shown the pilot jet 31 extends through a hole 34 to a slot 33 in the throttle slide. The air inlet port 32 may be closed or opened by a spring-loaded adjusting screw (not shown). The pilot jet is preferably normally closed by a spring-operated valve (not shown), the arrangement being such that when the slide .is in its closed position the pilot jet is open and when the slide is raiseda predetermined amount the pilot jet is closed by the valve. On closure of the throttle valve a step 22a of the needle valve 22 closes the outlet of the jet tube 15 and the throttle moves down relative to the needle 22 so that a spring 26 is compressed. In the case in which a sleeve is employed instead of a needle valve, when the throttle is closed the main jet tube lies within the sleeve and all the orifices of the main jet tube including a compensating orifice are closed. In this embodiment the usual centrepiece may be omitted and the central hole in the body of the carburetter closed and the feed to the main jet is taken through a downward extension of the same passing through a hole in the float. In the heads of the main and pilot jet tubes a small screw may be provided which can be removed when the jets have to be cleaned. The main jet tube above the compensating-orifice may be tapered. Inclined main jet orifices may be replaced by a single slit extending longitudinally of the main jet tube or by orifices on opposite sides. A taper needle may be used for adjusting the pilot jet and the sleeve may alternatively be used in a similar manner to the needle in a conventional carburetter arrangement. The carburetter may be used with two-stroke and four-stroke engines.
