Title: An Improved Box-Staying Unit.
Inventor: TURNER ARTHUR GEORGE
IPC: B31B3/72
Filed: 1967-09-07
Abstract: 1,189,706. Making boxes; cutting webs. A. G. TURNER. 4 Sept., 1968 [7 Sept., 1967], No. 40997/67. Headings B4B and B5D. A box staying unit, suitable for use in a machine of the kind in which side-forming wall portions of a box blank are folded relative to a central bottom-forming portion so that their edges are juxtaposed, includes a former block 23 which has a V-shaped groove (25), Fig. 2 (not shown), and a heater 24 and is advancable to and withdrawable from a corner edge (13<SP>1</SP>) of the folded box blank 13 supported on a former 9, a predetermined length 40<SP>1</SP> of adhesive coated stay paper 40 being fed during withdrawal of the block to a position adjacent the V-shaped groove (25) where it is severed by knives 28, 29 and applied to the box blank. In the embodiment described, a pneumatic servo 14 is secured to the former block 23, which includes an electrical heating element 24, and to a housing 27. A knife 29 notched at (34), Fig. 5 (not shown), and having a V-shaped slot (35) and cutting edges (36) is slidable relative to the housing 27 against spring bias and coacts with the knife 28 which is fixed to the former block 23. Stay paper 40 coated with thermoplastic adhesive is passed through a removable slotted member 39, over a roller 41 and between an upper resilient strip 43 and a curved lower such strip 44 around the lower part of a feed roller (45) on a shaft 60. The lower guide strip 44 is pressed against the feed roller (45) to corrugate and consequently stiffen the stay paper 40 before the latter is passed through the slot (35) in the knife 29. When the block 23 advances towards the box blank 13, the notch (34) of the knife 29 engages a corner of the former 9. As the block 23 continues to advance, the fixed knife 28 and the slidable knife 29 co-operate to sever the length 40<SP>1</SP> of stay paper which is then applied to the box blank 13. A bar 54 slidable in a fixed housing 12 has a slot 59 through which passes the feed roller shaft 60 with lost motion. When the lost motion between the slot 59 and the shaft 60 has been taken up, the bar 54 carrying the guide 44 &c. is advanced by movement of the housing 27 and a rack 61 on the bar meshing a gear (62) fast with an oscillating plate 63 drives the latter. A pawl 64 on the plate 63 then over-runs relative to a ratchet wheel 65 fast with the feed roller (45). On the return stroke of the servo 14, the bar 54 moves back under spring bias and the plate 63 is turned in the opposite direction, so that the pawl 64 drives the ratchet wheel 65 and the feed roller (45) to advance a further length 40<SP>1</SP> of stay paper 40. A screw 52 adjusts the effective length of the slot 59 and hence the length of the strip 40<SP>1</SP> of stay paper which is advanced. The block 23 may be formed with a slot (23<SP>1</SP>), Fig. 6 (not shown), to produce flanged bottom boxes.

Abstract: 1,223,439. Releasable fastenings. C. E. MARSHALL (WOLVERHAMPTON) Ltd. 14 July, 1969 [31 Aug., 1968], No. 41710/68. Heading E2A. [Also in Division H1] A control mechanism for a rotatable switch (an ignition switch is described), once the switch has been moved to the "fire" position and returned to the "Ignition Light" position, prevents retent movement to the "Fire" position until the switch has been moved to at least the "Suniliarias" position. The control mechanism comprises a housing 18 and a rotatable nylon body 10 containing a spring loaded plunger 14 having an enlarged rear end 22 and a rib 15 which normally engages in annular recess 16 in body 10. In the "off"' "Suniliarias" and "Ignition Light" positions, the front end 17 of plunger 14 projects beyond the edge of body 10 into cam slot 19, being held against the action of spring 23 by rib 15 being engaged in recess 16. When body 10 is moved from the "Ignition Light" to the "Fire" position the slope 21 on cam slot 19 cams plunger 14 inwardly so that rib 15 disengages from recess 16 and as this happens near end 22 of plunger 14 engages inner edge 26 of housing 18 and the mechanisms moves into the position in Fig. 2 at which the engine should start. When the body 10 returns to the "Ignition Light" position spring 23 urges rear end 22 into cam slot 20 so that if an attempt is made to repeat the movement to the "Fire" position, end 22 engages the end of cam slot 20 to prevent this movement and protect the starter motor from damage. If it is desired to return the switch to the "Fire" position, the switch must first be reversed to at least the "Suniliarias" position during which movement the sloping portion 25 of cam slot 20 cams plunger 14 hard into its normal position so that rib 15 re-enters annular recess 16 and end 22 is freed from cam slot 70.

Sweeping of the sample surface produces n(E) for each point and a distribution of, for example, Auger transitions. Apparatus, comprises secondary electron energy analyser 58, a detector 59 (e.g. channel electron multiplier type) of the analysed secondary electrons, means such as phase sensitive demodulator 34 for measuring in the detection signal the intensity of the frequency w component, reference voltage generator 56, and a recorder 36. Scanning of the energy is achieved by voltage ramp generator 70. Analyser 58 is preferably a cylindrical coaxial analyser but may be a grid or magnetic analyser. Transitions leading to emissions are discussed and Fig. 4 (not shown) indicates back-scattering of magnitude h 2 , random noise h b  and Auger peak h a . Detailed analysis is included with comparisons with the prior art analysers of Figs. 5 and 6 (not shown). Modulation of the primary beam may be 100% of m, + h a  (Fig. 4) rather than h 2 -h 1 , the signal noise ratio being improved and the phase sensitive modulator permits weak variation studies at the extremes of the curve n(E). The modulator 34 may be replaced by a bandpass filter, or a real time correlator or a Fourier transformation device. The X-Y recorder 36 may be replaced by an oscilloscope or A/D converter. Sensitivity may be improved by inserting a scintillator with a photomultiplier before the detector or any device receiving component w. The sample may be of Si, Cr or oxygen for example, the gun may be used with an LaB 6  crystal and a field emission gun further improves spatial resolution. The sample may be biological and may be the anode, or a supplementary anode plate may be interposed.

The wrapping blades of each pair are movable in opposite directions to one another, and transversely to the blades of the other pair. One pair of blades is located above the other pair of blades. A roller 169 is provided on the leading edge of each wrapping blade. The lifting platform includes a plate (99) Fig. 12 (not shown), on and against which upwardly extending cylindrical support members (100) are resiliently held by springs (103). The wrapping blades displace the support members (100) from vertical positions during the folding operation and support the article; allowing the supporting platform to be lowered. The film is supplied from a roll, transversely perforated at predetermined intervals by a pivoted and vertically movable plate and fed above the lifting platform between pairs of upper and lower endless belts 46, 47. The belts pass around driven rollers 49, 52, and idler rollers 48, 50 mounted on a frame which is reciprocable by means of a crank drive 20. The drive rollers 49, 52 are driven by gears rotated by a fixed rack 60 upon reciprocation of the frame. The length of the film drawn from the roll is variable by adjusting the throw of the crank drive 20. The clamping bars 194, 195 are spring-urged against the undersides of the lower conveyer belts 47. A pivotally mounted stop plate 193 constrains the article in the wrapping position from moving towards the discharge conveyer during the wrapping operation. The various components associated with the article feed, the wrapping operation and the discharge of the wrapped article are driven by a common motor through systems of gears, cams and levers. The crank drive 20 for the film feed is driven by a further motor.
