Title: Method of and device for measuring the length of a magnetizable object
IPC: G11B5/48
Filed: 1972-03-07
Abstract: 1346160 Measuring length of recording tape PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 March 1972 [10 March 1971] 10526/72 Heading G4H Apparatus for measuring the length of magnetic tape comprises means for recording on to the tape a regular, periodical signal and comprises an erase head and a playback head at a fixed, known distance apart such that the tape crosses the erase head first, the heads being connected via a switching transistor such that signals played back activate the erase head, this arrangement producing a pattern on the tape of blocks of the periodical signal alternated with erased blocks, the length of both type of block being that of the distance between the two heads, the length of the tape being determined by counting the number of block trains, i.e. the number of recorded and unrecorded pairs passing through. Interference which would lead to a wrongly marked tape and incorrect counting is obviated by the provision of a second counter which counts the number of wavelengths in a data carrying block. If the block is the right length or longer than this length the counter counts to, e.g. 80 before the signal at the playback head changes to indicate an erased block and an AND gate connected to this head and to the counter is not operated. If the block is too short, this gate is enabled to switch off the main counter and heads for a predetermined time.
Patent GB-105628-A (GB)
IPC: B60T8/18
Abstract: 105,628. Luard, E. S. April 20, 1916. Actuated or applied by weight of vehicles; fluidpressure; force-transmitting mechanism.-In order to limit the braking pressure to an amount depending on the load, the brake mechanism is adapted to lift the vehicle body so that the weight thereof reacts upon the brake blocks. Where the mechanism is actuated by fluid pressure, waste of power may be avoided by a valve arranged to cut off the supply of atmospheric air to the brake cylinder in a vacuum system, or the escape from the atmospheric side of the piston in a compressed air system when the vehicle has been lifted. A mechanism actuated by a vacuum cylinder 1 is shown and comprises a lever 16 pivoted upon the underframe at 19 and to the bearing spring 18 at 17 and connected by a rod 15 to a sway lever 6 which is connected by a rod 5 to the equalizing- connections 9, 12, 11 of the pair of brake blocks 13, 14. The sway lever 6 is connected also by a rod 4 to the power crank 2 and is suspended from the underframe either by a link 8 or a link 24 and a slot 22 in the pull rod 5. When the power is applied, the lever 16 at first remains fixed and the slack is taken up with the pivot 6' acting as a fulcrum. When sufficient force obtains in the system, the pivot 6<11> becomes the fulcrum of the lever 6, the lever 16 is turned about its pivot 17, and the vehicle is lifted. The lever 16 engages stops 21 on the underframe to limit the downward movement of the vehicle and to provide the support therefor when the brakes are not applied. The valve for cutting off the supply of air to the vacuum cylinder when the vehicle has been raised may comprise a plug cock 27 actuated by connexions 46, 47, 48, 49, a by-pass with a non-return valve being provided in the casing of the valve to permit of the evacuation of the cylinder for releasing the brakes. Fig. 4 shows a disk valve 29 for the same purpose, operated by a cam slide 42 with slot 44 and having the by-passages 36, 37 and a non-return valve 38. The valve is connected to the train-pipe at 33 and to the brake cylinder at 34. When a compressed air system is employed, a cock is arranged to cut off the escape of air from the atmospheric side of the brake piston so that the air on this side becomes compressed and checks the movement of the piston. The invention may be applied also to hand or other power mechanism. The Provisional Specification refers to the employment in connection with the invention of the brake mechanism described in Specification 18795/10.

Title: Improvements in or relating to coin-operated vending machines
IPC: G07F17/32
Filed: 1926-04-22
Abstract: 273,047. Wade, H., (Mills Novelty Co.). April 22, 1926. Delivery of articles stored in piles; fortune-telling apparatus; premium checks, delivering.-Relates to coin-controlled vending machines of the kind described in Specifications 246,621 and 248,114 which have in combination with the vending mechanism a plurality of legend displaying wheels for telling fortunes and other purposes and in which premium coupons or checks may be delivered. According to the invention, in order to prevent such checks from operating the check delivery mechanism while permitting them, as well as coins, to operate the regular vending mechanism, the coin-controlled mechanism for actuating the check-delivery mechanism has associated therewith mechanism capable of preventing the functioning of the check-delivery mechanism while permitting merchandise to be vended from the machine. The machine delivers articles, such as rolls of mint 106, from compartment A<1>, Fig. 6, by a rotary ejector C and premium checks from a magazine 7 under the control of legenddisplaying wheels, as described in Specification 246,621, means being provided as described in Specification 248,114 for preventing the check-delivery mechanism from operating, when a similar check is inserted in the coin shoot. The arm 98, which is on the main rock shaft 15 and bears a pawl 97 for engaging a link 92 connected to the locking pawl 91 for the ejector C, is however raised sufficiently far, when a check is inserted in the shoot 1, Fig. 4, to engage the projection 95 on the link 92 and thereby free the article vending mechanism. Its movement is limited, when a check instead of a coin is inserted, by a pin 116 on the arm engaging a projection 73b on a lever 73, which is allowed by the use of the check to move into the path of the arm. This prevents a link 114 from being lifted to withdraw a stop member 111 from the path of a lever member 108<b> which actuates a cut-off slide 107 in the check delivery shoot 104, as described in Specification 248,114, and thereby prevents the check-delivery mechanism from functioning.

Filed: 1921-04-12
Abstract: 182,584. Ireland, P. M. de C. April 12, 1921. Releasing - devices and supporting- arrangements for collectors.-The main spring of a trolly pole is located between the pole-carrier and a remote reactionmember, and this member carries a toggle which is actuated by a rod coupled to the pole to effect the disconnection of the spring with the carrier when the collector wheel jumps the conductor. The carrier 2, Fig. 1, is mounted at 3 on a base 1 which has a guide rod 23 threaded at one end to receive nuts 24<a> and carrying a sleeve 14 and compression spring 24. A rocking-frame 20 is pivoted at 19 to the sleeve 14 and carries an adjustable stop 22, lugs 20b for bars 16 pivoted at 2<c> to the carrier 2, and pins 7a for rods 7. The rods 7 support a crossbar 13 and a housing 8 for a spring 9 mounted on a sleeve 10, on which slides a bar 4, mounted on arms 2a of the carrier 2. The bar carries a latch 5 with a lug 5a engaging an adjustable stop 26 secured to the base 1. In operation, when the trolly 53 leaves the wire, the sleeve 14 engages the nuts 24a so that the nuts 16<a> on the bars 16 rotate the frame 20 and so release the pole 52 from the action of the springs 24. The pole then falls, compressing the spring 9, until the latch 5 engages the crossbar 13 and prevents oscillation of the pole. To re-set the pole, it is drawn down still further so that the bar 4 engages the housing 8 and through the rods 7 rotates the frame 20 into normal position, the stop 26 having released the latch 5 through its lug 5<a>. When tension springs 43, Fig. 9, are used they are secured to the frame 20 and to lugs on the carrier 2 between two compression rods 38. The carrier is pivoted to a sleeve 47 having recesses to receive keys or ridges on a tube or bar 46 secured to the base 1, a stop 48 being provided on the sleeve 47. The bar 46 may be rectangular. In a modification applicable with either tension or compression springs, Fig. 9, the rods 7 engage a bar 29 carried by arms 28 mounted on the pivot 3. The latch 5 is carried by lugs 32 on the carrier 2 and engages a bar 30 on the arms 28, being released by contact with the nut 1<a> of the base 1. The frame 20 is released or re-set through the rods 20 by means of stops 34, 35 on the carrier 2 which engage and rotate the arms 28.

Title: Improvements in or relating to position indicating devices
Inventor: GOLDER JACK ALEXANDER
IPC: G01D5/22
Filed: 1959-03-31
Abstract: 880,387. Electrical measuring systems. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 21, 1960 [March 31, 1959], No. 10816/59. Class 40 (1). A centre-tapped coil for indicating the position of a core attached to a rod is connected in a first bridge circuit which uses unbalance between the two halves of the coil to make it follow the core, and a second bridge circuit which senses the inductance of the whole coil to make it follow the core when the latter moves rapidly out of the coil, leaving the first bridge circuit balanced. As shown (Fig. 1), a magnetic core 34 is movable longitudinally in a tube 6 by a rod 33 to which it is attached. Located outside the tube 6 are two similar coils 29, 30 enclosed in a casing 24 with an extension bush 40 which is threaded to be moved by rotation of a threaded shaft 42. The casing 24 moves on guide rods 16 attached to end plates 13, 15, and the ends of the coils are brought out to carbon contact blocks attached to casing 24, moving alongside contact rods 17, also attached to end plates 13, 15, but electrically insulated therefrom. The shaft 42 is driven by a motor 45, and is geared to selsyn transmitter 55. A limit switch 56 is operated by the coil casing 24 in its bottom position. The coils 29, 30 form a bridge with a potentiometer 62 (Fig. 5), which is normally balanced with the core 34 located centrally in the two coils. A second bridge circuit has the two coils 29, 30 connected in series in one arm, a coil 64 constituting an adjacent arm, and a potentiometer 65 the other branch of the bridge. A relay R, connected in the unbalance diagonal of the second bridge, is normally unenergized, so that the output from the first bridge is fed via contacts R3, R4 and amplifier 67 to motor 45, which drives coils 29, 30 to follow the core 34 and rebalance the first bridge. Rapid movement of core 34 produces unbalance of the second bridge, relay R is energized and amplifier 67 is switched to the output of the second bridge. Motor 45 now drives the coils 29, 30 downwards. If the core 34 has moved upwards, the coil casing 24 operates switch 56 at the end of its downward travel, relay S is energized to close a holding circuit at S3, and reverse the signal to amplifier 67 at S1, S2. Motor 45 now drives the coil assembly upwards until both bridges are re-balanced. The rod 33 may be the control rod in a nuclear reactor. The core 34 may alternatively be located on a polythene float for determining liquid level.
