Title: Improvements in or relating to conveying and sealing apparatus
Inventor: RHINE WALLACE RICHARD
IPC: B65B43/12
Filed: 1962-11-30
Abstract: 955,244. Making bags etc.; cutting &c. DOUGHBOY INDUSTRIES Inc. Nov. 30, 1962, No. 45445/62. Headings B4B and B5D. [Also in Division B8] Polythene sheet F is conveyed on spikes 25 carried by a chain 21. In Figs. 3, 4 the sheet F is in the form of a flattened tube of polythene film and is intermittently fed by rollers 13, 13 into the position shown in dotted lines (Fig. 3). During a dwell period of the feed rollers 13, 13, a head 20 is slidable rightwards (Fig. 3) under the action of a spring 55 and as permitted by the low sector of a cam 62. The head 20 presses the sheet on to the row of spikes 25 carried by the L.H. run of the chain 21. A further cam 77 (rigid with the shaft 18 of the cam 62) engages a follower 75 to release a locking pin 72 thereby freeing a drum 68 for rotation. The latter results from the action of a chain 64 carried by a sector 63 rigid with the cam-shaft 18, as it comes into operative engagement with a sprocket 66 rigid with the drum 68. A cam track 69 (Fig. 4) of the drum 68 displaces a pin 78 rigid with a slide 79 mounted between pulleys 80, 80. The slide 79 acts through linkage 82, 83, 85 to displace a slide 44 along a slot 45 (Fig. 4). The slide 44 carries a sprocket 43 which engages a fixed run of chain 46. The sprocket 43 is thus caused to rotate and drive (at twice the speed of the slide 44) an endless chain 41 carrying a knife 39 which thereby severs the length of sheet carried by the spikes 25. As the high portion of the cam 62 engages its follower, the slide 20 is retracted and a linkage 86, 87 is deflected to operate a clutch 30 which restarts the chain 21. The severed sheet is thus fed to the nip between engaging runs of two endless conveyers 49, 50. The latter lead the sheet into engagement with endless bands 52, 52, of heat conducting material such as stainless steel. Associated with the latter are heat applying bars and cooling bars (Fig. 5, not shown) which effect heat sealing of the severed edges of the flattened tube of polythene. This action also serves to remove the holes produced by the spikes 25. In the embodiment of Fig. 6, polythene bags 90 filled with articles (e.g. folded bed sheets or fruit) are carried on a conveyer 91 with their open ends supported on an auxiliary coil-spring type conveyer belt 92. This leads the flattened bag mount up a ramp 93, the end of which has a slot through which protrude spikes 95 on an endless conveyer chain 101. A brush 98 is carried periodically by a linkage 99, 100 into engagement with the bag to drive it on to the spikes 95. A vertical plate 102 serves to prevent the articles in the bag fouling the conveyer 101. The longitudinal axis of the conveyer 101 slants slightly away from the longitudinal axis of the plate 102 so as to tension the bag mount away from the articles in the bag. The bag mouth is thereby conveyed to sealing apparatus (not shown) similar to that described above.

Abstract: 1,101,582. Fluid-pressure brakes. HARRY FERGUSON RESEARCH Ltd. 10 Nov. 1964, [16 Nov., 1963], No. 45518/63. Heading F2F. In a fluid-pressure braking system for a vehicle, comprising a master cylinder 67 containing a piston or pistons 65, 66 which are operated by a pedal 71 via a servomotor 11 which acts as a booster and is controlled by a pedal-operated valve, a rotary inertia device 10 is adapted in response to rapid deceleration of the vehicle to control an amplifying arrangement 14 which is adapted to reverse the fluid supply to the servomotor whereby it acts forcibly to release the brakes in opposition to the pedal pressure. In the embodiment of Fig. 1 the inertia device 12 operates in response to rapid deceleration to move a rod 95 to the left, shutting off chamber 97, which is open to atmosphere, from a pipe 102, and connecting the latter via a pipe 101 to a vacuum reservoir 10. The resulting vacuum in chamber 32 of the amplifying valve acts on diaphragm 31 to move a rod 41 carrying valve elements 43, 44, the valve 43 acting to cut off an atmosphere connected chamber 33 from a pipe 55 supplying the atmospheric inlet chamber 74 of the vacuum suspended servomotor 11, which has a vacuum chamber 73 and a control chamber 72 connected selectively to vacuum or atmosphere by the usual lapping valve arrangement, and to connect chamber 74 to vacuum tank 10 via a pipe 21, while the valve 44 cuts off the vacuum chamber 73 of the servomotor from the vacuum pipe 21 and opens it to atmosphere at 29, so that the servomotor operates in reverse against the force applied by the pedal 71 acting via the lapping valve arrangement. The latter comprises a plunger 64, for direct pedal operation in the event of power failure, a valve element 85 carried by the plunger operable to close against a valve disc 82 to shut off connections 76, 77, 79 between chambers 72 and 73, and a resilient annular plate 80 which, on pressure being applied to it by element 85 via the disc 82, flexes whereby disc 82 moves forwardly to open communication between chamber 72 and chamber 74. In the modified embodiment of Fig. 2 (not shown), a switch (115) operated by the inertia device (112) controls a solenoid (206) acting on a rod (141) of the amplifying valve, these items replacing the valve operated by the rod 95 in Fig. 1, and the diaphragm 31. The amplifying valve and servomotor are otherwise identical with those of the Fig. 1 embodiment.

Filed: 1975-11-05
Abstract: 1531748 Frequency changing TENNA POWER CORP 5 Nov 1975 [22 Jan 1975] 45932/75 Heading H2F In a method of converting multi phase high frequency electrical energy to single phase, low frequency energy, the high frequency energy is rectified by means of a controllable rectifier 16 in such a way as to produce bursts of pulsewidth modulated uni-directional energy and inverting alternate bursts so as to provide the desired A.C. output. The invention is applicable to obtaining 60 Hz A.C. from a 720 Hz 12 pole, three-phase automobile alternator driven by a petrol engine. The stator of the alternator 12 is coupled to a bridge 16 of three thyristors 120, 122, 124 and three diodes 132, 134, 136. Triggering thyristors.-The voltage across two of the stator windings 24, 26 is reduced by transformer 86, rectified by diode 150 and limited by zener diode 158 before being coupled to a commutating slip ring arrangement 201, 202 driven in synchronism with the alternator 12. When the slip ring 202 contacts brush 162 thyristor 120 is turned on giving the narrow pulse at the leading edge of the bursts shown in Fig. 2 and on a larger scale in Fig. 3. When slip ring 202 bridges brushes 162 and 164, thyristors 120 and 122 are turned on giving a second, wider pulse. Similarly when slip ring 202 bridges all three brushes 162, 164, 166, all three thyristors are turned on giving the wide pulse in the centre of each burst. Contact-making inverters. The uni-directional bursts are coupled via brushes 100, 106 to a further slip ring arrangement 14 driven at half the speed of the alternator 12. Brushes 204, 208 provide a 60 Hz output at 212, 214 by contacting slip rings 206, 210 alternately. Excitation of alternator.-The system is started by means of a pulse 42 from the ignition system of the engine which is rectified at 44 and passed by diode 38 and brushes 64, 68 to the rotating field 30 of the alternator. When the alternator is generating, a voltage at the secondary 84 of transformer 86 is rectified at 88 and regulated at 92 so as to continue to provide excitation. Diode 38 disconnects the starting field supply.
