Abstract: 745,422. Labelling machines. NEW JERSEY MACHINE CORPORATION. Aug. 31, 1951, No. 20620/51. Class 73 [Also in Group XVII] In a labelling machine for objects where the label is to be applied to a non-planar surface means are provided to shape the label before its application. Labels 9 having a heat activatable adhesive are transferred from a hopper 16 by a suction pick-up device 11 and deposited on a support 12 from which a transfer device 13 removes them, after shaping, and applies them to, e.g. the interior of a hollow cylindrical object 14 on a support 15. The transfer device 13 is heated to activate the label adhesive and is mounted with the device 11 on a common member 20 which is reciprocated vertically and horizontally between the various stations 9, 12, 15. The transfer device 13 has a label carrying surface 39, Fig. 3, to which suction is applied, which is complementary to a label supporting surface 38 of the support 12. When the pick-up device 11 deposits a label on the .surface 38 suction is applied thereto to shape the label. The device 13 may then contact the label with suction applied to the surface 39 or pressure may be applied to the surface 38 to blow the shaped label on to the surface 39 without the two surfaces contacting. A modified label support has a flexible strap 12<SP>1</SP>, Fig. 4, mounted on pins 46. 46 on standards 47, 47 maintained normally vertical by springs 49, 49. The label supporting surface 38<SP>1</SP> of the strap 12<SP>1</SP> is provided with suction holes 37<SP>1</SP>, the arrangement being such. that the transferring device can engage a label 9 deposited flat thereon and force down the strap 12 until the label is shaped around its face and is held thereon by suction. In such a case the transfer device may be tubular in form so that the label becomes wrapped around it and can be applied to the inside of a tube, in which case adhesive need not be used. U.S.A. Specification :2,227,816 is referred to.

Abstract: 1,207,208. Controlling compressors. CATERPILLAR TRACTOR CO. May 2, 1968, No.20805/68. Heading F1N. An air compressor 13 driven by a turbocharged internal combustion engine 11 supplies a receiver 17 when air is drawn off through an outlet 21, but when air is no longer drawn off, the engine is caused to idle and the compressor output 34 is returned to the compressor inlet 14 via the atmosphere or through a by-pass conduit 30 containing a by-pass valve 37. When air is not drawn off through the outlet 21, pressure builds up in a Venturi sidearm 27 to cause an engine governor 24 to set the engine to idle. The consequential drop in pressure in the engine inlet manifold 12 causes closure of a valve 31 in the compressor inlet 14 and also the opening of a switch 39 controlling the by-pass valve 37. The pressure switch 39 also controls a valve 53 in a line 58 for returning lubricating oil separated from the compressor output to a pump 22. The valve 53 normally connects an oil line 23 from the receiver 17 to the return line 58 but when the switch 39 is opened during engine idling, an oil collector 48 in the by-pass conduit 30 is connected to the return line 58.

Abstract: 1,105,517. Coin-freed lockers. J. A. SMITH. 21 May, 1965 [28 May, 1964], No. 21555/65. Heading G4V. [Also in Division E2] A coin freed lock for e.g. a luggage locker comprises a latch bolt 31 in the locker door 26 with an abutment 77 normally engaged by a pivoted locked lever 74 which is cammed by a coin (or the topmost coin) 70, when in operative position in a shoot in the bolt 31, to permit the bolt to be rotated clockwise by a key to its operative, locking position (Fig. 6, not shown) in which it discharges the coin(s) into a receptacle 29 in the door post. The look may be adapted to be operated by one coin only retained in the bolt until it is returned to its initial position, return rotation of the bolt causing the coin to drop by gravity into a coin return receptacle 61, by removing a stop in the bottom of the coin shoot in the bolt 31 and suitably positioning a spring 102 at the top of the shoot (Figs. 11-14, not shown). A pivoted lever 80 drops when the door is opened so that one of its arms 83 contacts an abutment 85 on the lever 74 to prevent operation of the lock. Arm 82 of the lever 80 is held in the position shown in Fig. 1, when the door is closed, by a magnet 84 on the door post. Coins are inserted through a side opening adjacent magnet 84 and a magnet 63 blocks passage of ferrous slugs into the bolt 31. If anyone inserts a coin and then tries to retrieve both key and money by partially rotating the bolt but opening the door before the bolt can enter the aperture in the door post, (Figs. 9, 10, not shown), the bolt is jammed part-way out to signify attempted fraud. The lock is actuable by different selected numbers and sizes of coins by inserting headed pins 53 into selected apartures 56, 62 and 64. An owner's look cam 42 has four operative positions in one of which it permits the entire lock mechanism to be removed from the door.

In a wrapping-machine in which articles 2 enclosed in wrappers 1 are fed, as by a conveyer 4, between heat-sealing devices 5 which secure the end folds of the wrappers, each device comprises in one form, Fig. 3, a moving endless metallic band 6 with which the surfaces to be sealed make sliding contact. The band passes over a hot-plate 7 and driving rollers 8, coupled by a chain 10, and is moved in the opposite direction to the conveyer 4 or in the same direction at a different, preferably slower, speed so as to provide a continuously changing area of contact with the heat-sealable material of the wrapper. The accumulation of a deposit of thermo-plastic material on the operative surface of the band is thus avoided. One or both rollers may be adjustable for tensioning purposes, and the frame 9 on which the device is mounted may be adjusted relative to the conveyer. The speed of the band is preferably such that it takes about one hour to complete a cycle of movement. The band may be removed for cleaning and a fresh band substituted after each cycle. Alternatively, a wick 11, situated in advance of the hotplate, may be provided to apply a heat-resisting oil to the band, and a scraper 13 and brush 12 may be arranged to bear on the band after it has passed over the hot-plate to remove deposit and apply a solvent or other cleansing agent, so that the band may work continuously without periodical removal. In a modification, Fig. 5, the band is non-continuous and has its ends coiled on drums 10, one drum being driven to pull the band past the hot-plate 7.

Abstract: 1,118,246. Measuring displacements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 10, 1967 [May 16, 1966], No. 21665/66. Heading G1N. The vibrational displacements of a shaft in a bearing, measured by a pick-up coil PU1, are added to the movements of the bearing itself, determined by double integration of the signal from an accelerometer A, to obtain the absolute movement of the shaft in space. The coil PU1 is connected in a bridge circuit fed by oscillator OSC. The signal from the accelerometer A is fed through an amplifier CA, double integrator DI and further amplifier CDA to a Hall plate element H where it modulates the oscillator output. The two modulated signals are mixed at M and demodulated at DEM to give the required displacement signals. One arm of the pick-up bridge circuit is a coil L located in the same housing as the coil PU1, to provide temperature compensation.
