Abstract: 1,233,189. Applying lids to containers. AUTOPACK Ltd. 4 Aug., 1969 [17 May, 1968], No. 23540/68. Heading B8C. A machine secures lids to metallic-foil containers 10 by placing a lid on a ledge 11 of a container and folding the upstanding wall portions 12 of the container over the lid. Filled containers 10 in predetermined spaced relationship are pushed along a stationary plate 16 on to a platform 26 by bars 14 on a pair of endless chains 15. The platform 26 is then lifted by parallel links 27, 28 actuated by a cam 32 so that L-shaped members 63 constituting a split die plate, Fig. 4, of a work head 18 lie below the level of the ledge 11 of a container. These L-shaped members 63 are then moved inwardly to a position beneath the ledge 11 by a mechanism comprising parts 65, 67, (68), rods (71, 72) link (73) and rod (74). The workhead 18, which is supported on oscillating parallel links 19, 20 then moves, along with the container 10, to the right and a suction head 47 carries a lid 98 from a swingable magazine 99 and deposits it on the container. L-shaped edge folding members 50, Fig. 4, located above the L-shaped members 63 are then actuated by a mechanism comprising a reciprocating rod 62, link (60), rods (58, 59), levers (55), rods 54, and links 53, 52, so as to move diagonally of the rectangular container 10 to fold the upstanding wall portions 12 on to the lid. Suction to the pad 97 of the suction head 47 is applied by a pump 46. A motor 45 imparts motion to all the parts of the machine. Containers of different shapes and sizes can be lidded, and the height of the stationary plate 16 and the chains 15 with respect to the workhead 18 is adjustable by screw rods 105.

In a connection wherein a rotatable conduit member, e.g. drying drum 10, Fig. 1, is fluidtightly connected to and drives a nipple 35 rotatably mounted in a stationary conduit part, a combined pipe joint and detent clutch is provided between the nipple 35 and the rotatable member so that the two may be joined or separated while the member continues to rotate, the clutch mechanism being operated by a manually-operated means 46 which is movable axially with respect to the joint. In the embodiment shown, Fig. 2, an extension 34 of the nipple 35 has an enlarged end 42 counterbored at 44 to accept an extension 36 of the journal flange 20 of the drying drum 10. Fluid sealing is achieved by O-ring 64, and the overlapping of ring 68 prevents turbulence. Mechanical coupling is via balls 54 in radial bores 56 engaging in depressions 58 circumferentially spaced round extension 36. The depressions 58 are circumferentially elongated (Fig. 3, not shown) to assist location of the balls when the clutch is engaged by sliding the spring-pressed collar 46 into the position shown. To disengage the nipple 35 from the drum 10 the collar 46 is manually slid leftwards and the balls are cammed, by continued rotation of the drum, into groove 60. The arrangement is particularly suited to the drying rollers of paper-making machines so that the machine need not be stopped for repairs to rotary seal 28.

Abstract: 1341833 Analogue to digital converters SOLARTRON ELECTRONIC GROUP Ltd 30 April 1971 [11 May 1970] 22750/70 Heading G4H In an A/D converter a digital output is derived from a frequency which is proportional to the difference between an input voltage and a feedback voltage, in the feedback circuit the frequency being divided by a counter and for each pulse therefrom a standard charge pulse is generated, which charges are smoothed to provide the feedback voltage, there also being a D/A converter responsive to the counter to provide a cyclic staircase waveform to at least partially cancel the A.C. component of the smoothed pulses of charge. In Fig. 1 a floating input voltage is applied to terminals 10 and 11 and the feedback voltage to terminal 11, to produce a difference voltage to a voltage to frequency converter 14. The feedback voltage is taken from a differential amplifier 19, to which an off-set voltage (18) is applied to allow input voltages of either polarity, and applied to terminal 11 via a range attenuator 23. The frequency from converter 14 is gated to counter 28 for sample periods to provide the digital output. The frequency is also divided by counter 36, each overflow pulse therefrom operating, via counter 42, a standard charge generator 20, whose output charges are smoothed in filter 22 to produce a feedback voltage to differential amplifier 19. The filter 22 is A.C. coupled via capacitor 38 to a D/A converter 37 providing the staircase waveform in response to the cycling counter 36. Counter 42 functions as an overload detector. Each pulse from 36 steps the counter on, each charge generated by 20 steps it back and if the arrival of pulses from 36 exceeds the production of charges from 20 a predetermined count is reached which inhibits the voltage to frequency converter 14. The system is automatically calibrated for positive and negative voltages by circuit 56 (also Fig. 6, not shown) which via switches 62, 63 connects a standard cell 57 to the input terminals 10, 11. Any divergence of the counter reading 28 from a standard reading causes pulses to be introduced to bring the counter reading back to the standard, the pulses also being integrated from which a zero offset voltage 58 is derived for input to amplifier 19 and a chopped slope correction voltage 59 for input to filter 22.
