Title: Token issuing machines
IPC: G07F17/42
Filed: 1971-07-21
Abstract: 1361030 Ticket issuing; cash boxes LICENTIA PATENT-VERWALTUNGS-GmbH 21 July 1971 [22 July 1970] 34129/71 Headings G4T and G4V In a machine for issuing tokens or tickets and including printing counters for registering the value of cash received for tokens or tickets issued and for registering numbers of tokens or tickets within the machine, a print-out is made from the counters on to a voucher both (a) when an empty cash-box is inserted into the machine, e.g. at the beginning of a new shift by the machine attendant, and (b) when the cash box is removed from the machine, e.g. when it is full or at the end of a shift. When the cash box is inserted into casing 11b (shown empty in Fig. 3), switch K is moved to its "2" position, Fig. 5, to energize the "2" contacts of switches M, H, P. Switches M and H are already in their "2" positions (this is shown in Fig. 4, but not in Fig. 5) so that over lines M3, H3 a motor and a half-revolution device are energized to rotate a shaft 10 clockwise through 180 degrees. Shaft 10 carries cams (not shown) which shift a voucher carrier 1 from position 1b to position 1c and operate a print hammer 3 to print the initial states of the counters (contained in unit 2) on to the voucher. During this half revolution, a cam 9 moves switches M, H to their "1" positions. At the end of this half revolution, Fig. 2 (not shown), a cam 8 allows clockwise rotation of an arm 6 if, in error, no voucher has been inserted in carrier 1. Switch P then opens to block dispensing of tickets or tokens. If carrier 1 does contain a voucher, rotation of arm 6 and opening of switch P are prevented to enable the machine. The components shown remain in the positions now reached (and shown in Fig. 5) until removal of the cash box. When the cash box is removed, switch K moves to its "1" position to energize the motor and half-revolution device over contacts M1, H1. The cams (not shown) on shaft 10 shift the voucher carrier 1 slightly to the right from position 1c and the final states of the counters are printed. During this second half revolution, cam 9 returns switches M, H to their initial ("2") positions. The date and time of the printing operation may also be printed on the ticket.

Title: Side delivery rake
Inventor: JARDINE CHARLES BURGESS
IPC: A01D78/06
Filed: 1956-11-08
Abstract: 846,901. Hay-making machinery. BARTRAM & SON PROPRIETARY Ltd., J. Nov. 8, 1956, No. 34151/56. Class 6(3). A side delivery rake comprises a main frame 1 set obliquely to the direction of advancement of its traction vehicle, and supporting a driven, endless chain 7 on which are pivotally mounted tines 27. The main frame j comprises two vertically spaced tubes 2 joined at one end (see Fig. 2) by plates 3 supporting the driving shaft 5 of a sprocket wheel 6 round which the endless chain 7 is entrained, the shaft 5 being driven from the power take-off of the traction vehicle. At their other ends, (see Fig. 3), the tubes 2 are joined by adjustable plates 15 supporting the shaft 17 of a freely rotatable sprocket wheel 18, adjustment of the plates effecting variation in the tension of the chain 7. The frame also comprises spaced, rectangular brackets 19 to which are fixed steel runners 21 for guiding and supporting the upper and lower runs of the endless chain, some links of the chain being provided with lugs 24 for engagement with the runners. Some links of the chain are also provided with small, roller-carrying brackets 22, (see Fig. 9), the rollers engaging a trackway fixed to the bases of the brackets 19 and thereby preventing sagging along the lower run of the chain. Every second or fourth link of the chain supports a mounting assembly 26 for a tine 27, each assembly comprising two U-shaped brackets 29 and 33, the upper end of the tine 27 passing pivotally through the side arms of the brackets, and through a helical spring 31 located therebetween. The tines on the lower run of the chain are maintained normally in a vertical position firstly by rollers 38 attached to the brackets 33 engaging on a trackway 39 fixed to the brackets 19, and secondly by the action of the springs 31 which urge the tines against stops 36 provided on the brackets 29. On meeting obstructions, the tines are deflected out of the vertical, away from the stops 36; against the action of the springs 31. The trackway 39 only extends along the lower run of the chain, so that as the tines begin to travel round the sprocket wheel 18 (see Fig. 3) the rollers 38 are disengaged from the trackway and the tines are free to pivot under the action of the springs 31 and pass behind a keeper bar 42. The keeper bar 42 folds the tines against the chain, and in this folded condition the tines travel along the upper run of the chain towards a laterally movable bar 43 (see Fig. 2). The bar 43 can be adjusted to guide the tines either into engagement with the trackway 39, in which case the tines are brought to an erect position ready for raking, or behind a ramp 40 in which case the tines are held in an inoperative position, thus facilitating the transportation of the device. In a simplified modification, the tine-mounting assembly comprises only one V-shaped bracket.

Title: Liquid level indicator
IPC: G01F23/34
Filed: 1929-11-12
Abstract: 343,909. Liquid level indicators. GIERS, C. A. DE, 42, Pilgrim Street, Forest Hills, New York, U.S.A. Nov. 12, 1929, No. 34460. [Class 123 (i).] A liquid level indicator comprises a float operating a pointer through a pivoted member which is enclosed in a flexible sleeve to seal it from the contents of the tank. A pointer 24 is mounted on a spindle 34 carrying a pinion 44 engaging a toothed sector 46 carried by an arm 48 pivoted at 50. The arm 48 carries a disc 52 to which is attached one end of a flexible sleeve 54, the other end being attached to the casing 40. The chamber 28 is thereby sealed from the contents of the tank 64. The instrument is attached to the tank by a tubular support 66, and a flange 70 carries a tube 74 through which passes a link 82 connecting the float arm 78 to an arm 62 attached to the arm 48. The attachment of the arm 62 to the link 82 is by means of a block 90, secured by a set-screw 92 and pivoted to a yoke 96 connected adjustably to the link 82 by a right-and-left screw 98. The pointer is adjusted to zero by the screw 98, and the block 90 may be adjusted along the arm 62 to compensate for slight variations in tank dimensions. Fig. 8, not shown, illustrates a modification with a vertical dial, and Figs. 9, 10, 11 (not shown) illustrate a form in which all the mechanism is contained within a tube,which projects from and carries the dial at any desired distance from the tank. Fig. 12 illustrates a simplified construction in which the body 150 carries a tube 158 with lugs 160 to which the float arm 162 is pivoted by a pin 166. The pin 166 has two eccentric projecting pivots 168 which actuate a vertical link 170 pivoted to an arm 172 which extends through the flexible sleeve 176 to actuate the pointer 184. In another modification, Fig. 16, the float arm 206 is bifurcated and provided with trunnion pins having an eccentric pin 214 passing through a slot in a yoke 220, so that movement of the float in consequence of level changes causes a horizontal movement of the yoke 220. The yoke 220 is attached to the ends of two flexible sleeves 222, 224, and to a rod 230, notched at 234, Fig. 21, to receive a crank-pin 236, Fig. 22, the shaft of which is journalled at 242. The crankpin carries a wire 244 with pointer 246 moving over the scale 250. The interior of the indicator casing, including the sleeves 222, 224, may be filled with glycerine to prevent condensation of moisture on the interior of the glass. In another modification, Fig. 23 (not shown), Figs. 25 and 27, an eccentric pin 288 projecting from the pivot of the float arm 284 operates between lugs projecting from the head 274, 278 of the flexible sleeve 272 so as to oscillate it about the pivot 280. The part 278 has a forked extension 290 engaging the crank-pin 292 of a shaft 294 which carries a wire arm 300 bearing the pointer 246. Specification 136,710, [Class 80 (iii), Linkwork &c.], is referred to.

Title: Wide band angular displacement and velocity sensor
IPC: G01H1/10
Filed: 1974-08-06
Abstract: 1468417 Measuring angular displacement electrically SYSTRONDONNER CORP 6 Aug 1974 34621/74 Heading G1N A transducer assembly for measuring angular displacement over a wide frequency range comprises a solid and a fluid inertia mass each associated with a pick-off to develop a signal voltage which is also fed to individual restoring means to bring the moving members back to their normal position relative to the respective pick-off. The solid inertia mass 10 Figs, 2, 3 constituting the LF transducer is attached to a base 12 by a flexure support 11  and by a taut, spring-loaded wire 41. Angular displacement of the assembly about its central axis is sensed by pick-off 13, e.g. a fixed differential inductance and an armature 16 carried by the inertial mass 10, to produce a proportional current which is fed to moving torquer coil 46 co-operating with fixed magnet 48 to restore the mass 10 to its normal position relative to the base, as sensed by pick-off 13. The HF transducer assembly comprises a moving member carrying a paddle 55, Fig. 5 and an armature 29 in a fluid 53 also contained in flow-path 52, constituting the fluid inertia mass, whereby angular displacement of the assembly about the axis through the pivots 58 is sensed by  pick-off 28 to produce a proportional current which is fed to moving torquer coil 59 co-operating with fixed magnet 61. The servo loops for each transducer incorporate electronically the appropriate desired LF and HF characteristics, and, in the case of the LF transducer using the solid inertia mass 10, embodies a positive feedback loop to compensate for mechanical friction. The torque current signals are fed through appropriate band pass filters and summed. The transducer assembly may be used on e.g. a moving TV camera to remove noise due to extraneous angular displacements.
