Title: Improvements in or relating to vacuum gauges
IPC: G01L21/04
Filed: 1939-07-27
Abstract: 531,603. Vacuum gauges. JACKSON, L. MELLERSH-. (Flosdorf, E. W., and Coleman, J. C.) July 27, 1939, No. 21893. [Class 106 (ii)] A gauge of the McLeod type comprises an integral V-shaped structure containing mercury, one leg of which structure includes a compression chamber 1 having a measuring capillary la, the structure being so mounted that the capillary 1a may be moved from the vertical position to a position where the mercury flows out of the capillary 1a and compression chamber 1 into the opposite leg 2 of the structure. The lower end of the chamber 1 has a mouth 1b which extends into an enlarged portion of the connecting tube 2. A second capillary tube 3 of the same diameter as and parallel to the tube 1a is connected by the tube 3a to the connecting tube 2a. The upper end of the tube 3 connects with a trap chamber 4 which is connected to the levelling tube 2 at 4a. A byepass large diameter tube 5 connects the lower end of the tube 2a with the trap chamber 4. The latter has a nipple 4b by means of which a connection is made from the gauge to the low pressure space to be examined. The mercury is introduced through this nipple. A tube 4c extends from the nipple into the chamber 4 and has an opening 4d at the centre of the chamber. The device is mounted in a casing 6 which is pivotally mounted on a bracket 8 provided with lugs so that the device may be swung from the position shown in full line to that shown in dotted lines where all the mercury runs into the chamber 2 and the bulb 1 and capillary 1a are in communication with the vacuum to be measured. A restriction 2d prevents violent movement of the mercury.

Title: Improvements in automatic coin freed vending machines for packets and the like
IPC: G07F11/16
Filed: 1925-09-04
Abstract: 262,500. Avery, Ltd., W. & T., and Bradley, L. C. Sept. 4, 1925. Delivery of articles stored in piles; coin action, thrust and weight.-Packets 3 piled in a magazine 4 are normally supported by hook-like members 22 carried by spindles 21, 23 which are connected for movement together by links 24 - - 26. A coin, inserted in the slot 5<a>, is thrust between two rollers 6, 7 so that an arm carrying the roller 7 is depressed against a spring 8 and through links rotates a shaft 14 carrying arms 16, 17. The cam 17 acts on a rollerbearing arm on a shaft 32, which is thereby rotated to raise a flap 33 into position to support the bottom packet of the column, when it is allowed to drop. The flap is held in this position by a pin 35 on an arm 34 of the shaft 32 engaging behind a projection 36<a> on the upper jaw of a trip lever 36 which projects into the coin shoot 5. The cam 16 acts on the roller 18 of an arm 20 carried by the spindle 21 to rotate this shaft and release the members 22 to allow the column of packets to rest on the flap 33. The cranked end 30a of a rod 30 is also moved into the shoot 5 to prevent the coin from dropping while the members 22 are disengaged from the column. The spindle 21 is returned by a spring 31 to cause the members 22 to engage and support the lowest but one of the column of packets, a dash-pot 29 connected to the spindle 21 by an arm 27 timing the operation. When the column is again supported by the members 22, the obstruction 30<a> is withdrawn from the shoot 5 allowing the coin to drop and trip the lever 36. This allows the flap 33 to drop and deliver the bottom packet supported by it.

Abstract: 952,201. Magnetic structures. RADIO CORPORATION OF AMERICA. June 23, 1960 [June 30, 1959], No. 22103/60. Heading H1H. A magnetic recording element in the form of a tape, disc or cylinder is produced by coating a suitable support member with a liquid layer comprising magnetic particles and a binder, applying superimposed alternating and direct magnetic fields, the alternating field being preferably perpendicular to the layer, and of sufficient strength to move the magnetic particles in the liquid, and then solidifying the layer. The unidirectional magnetic field is preferably applied parallel to the direction along which recording will take place. Apparatus for preparing a magnetic recording tape comprises a table 27 over which the tape 21 passes and a doctor blade 29 which levels the liquid layer applied to the tape at 31. The tape then passes over an A.C. solenoid 35 and through a D.C. solenoid 43, surrounding the A.C. solenoid and the tape, after which the liquid layer is solidified and the binder cured in a hot-air drier 47.

Sugar-cane cutting machines.-A machine for harvesting canes &c. comprises conveyer mechanism combined with means for stripping off the leaves or trash and cutting off the tops and then cutting the canes close to the ground. Fig. 2 shows a motor-driven machine mounted on two rear wheels 2 and a front steering-wheel 3 which is steered by means of a hand-wheel 4, row 5, and gearing 6. The stripping and topping mechanism is mounted on an inclined frame 7. The canes are collected together, arranged in a thin line, and then drawn between rotary stripping- brushes 11 by endless chains 8 provided with projecting fingers and by a rotary jointed rod 10 which is helically grooved. The stalks are bent over by the jointed rod 10 and the tops are cut off by toothed cutters 12. The lower cutter is fixed and the upper one is reciprocated by means of crank disks 16 and connecting-rods 17. The cutter teeth are rectangular in plan and sharpened on both sides. The apparatus for cutting the canes near the ground comprises two rotary circular cutters 19, Fig. 5, and two projecting fixed cutters 20. The cut canes are conveyed between two rotary brushes 21 which complete the stripping operation. They are subsequently collected and bound into bundles by mechanism on the machine. The fixed cutters 20 may be dispensed with. According to the Provisional Specification, the canes are cut between a rotary circular cutter and a fixed blade curved round it.

Title: Improvements in or relating to automatic starting devices for internal combustion engines
Filed: 1932-08-11
Abstract: 408,589. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Aug. 11, 1932, No. 22480. Convention date, Aug. 11, 1931. [Class 38 (iv).] In an electric starting system for internalcombustion engines in which de-energization of the starting motor SM is effected in response to rotation of an engine-driven generator 21, the generator is driven through an over-running clutch, 25, 26. Manual closure of an ignition switch 15 causes energization of a coil 14 controlling a switch 13 in the circuit of the starter motor. During cranking, an armature 17 is held in its upper position by the cranking current and when this falls due to self-operation of the engine, the armature 17 is drawn down to open contacts 18 in the circuit of the coil 14 and so deenergize the starter circuit. A coil 19 energized from the generator 21 holds the contacts 18 but if the engine stalls these contacts are reclosed to re-start the engine, a time delay being, however, introduced by the over-running of the generator whose rotation continues after the engine has stopped and by the vibration of an inertia piece 53. An inertia member may be attached to the generator shaft. In a modification the coil controlling the starter switch coil is energized, on closure of the manual ignition switch, by the difference of the voltage of the battery and of the generator, the apparatus 16, 17, 19 being dispensed with. The coil becomes de-energized when the generator voltage rises due to self-operation of the engine. The generator is driven through an over-running clutch to ensure that engagement of the starter pinion with the engine flywheel shall not occur until the engine is at rest. A dash pot may be provided on the armature of the starter switch. In a further modification the starter switch coil is energized from the battery through a manual ignition switch and a centrigugal switch mounted on the shaft of the generator which is driven from the engine through an over-running clutch. Specifications 374,246 and 379,362 are referred to.
