Title: Improvements in or relating to machines for assembling cardboard boxes
IPC: B31B3/64
Filed: 1958-01-06
Abstract: 888,482. Box-erecting machines. CHAPMAN Ltd., H. W., and GUMMER, H. F. April 6, 1959 [Jan. 6, 1958], No. 469/58. Class 18. A machine for securing both ends of a box or lid made from the blank shown in Fig. 1 by applying simultaneously heat and pressure to activate the adhesive shown in the shaded portions of Fig. 1 comprises platens 6, 8, electrodes 26-28, presser plates 23, a change-over valve 20, high-frequency heating means 25 and timing means 30 therefor. The blank is folded manually, inverted on the platen 6 and pressed down towards platen 8 where hook members turn in the portions 5 of the blank Closing of the platens causes a screw 18 to actuate a micro-switch 19 thereby changing over the valve 20 and causing pneumatic cylinders 21 to advance the plates 23 to press against the end flaps of the box. These plates are preheated when in their retracted position by heaters 31. When the plates grip the box a switch 24 closes and the electrodes 26-28 are heated. The timer 30 breaks the circuit of the heater 25 and the valve 20 after a predetermined time interval. A dielectric 29 prevents flashover between the electrodes 27, 28. Two machines can be arranged at right angles with the heating and control equipment between them for supervision by a single operator. The platens can be replaced by platens of different size to take different sizes of box or lid. The electrodes in the platens can be arranged in parallel, a strip of mica being interposed on the upper platen to compensate for the thickness of the portion 5 opposite the lower platen. The flaps extending from the side walls 2 could overlap to form a double thickness wall over the whole or part of the depth of the box.

IPC: B64C35/00
Filed: 1941-01-14
Abstract: 564,280. Seaplanes. MARTIN, J. V. Jan. 14, 1941, No. 497. [Class'4] An ocean-going, normally water-borne seaplane comprises a horizontal main wing 1, having upturned ends as shown, mounted upon two boat hulls secured beneath the horizontal portion of the wing. Navigation tops 59, Fig. 13, serving also as machine gun posts, are supported by tripods from the main wing into which they can be lowered to lie flush with the upper surface before taking off for flight. Guns 48 are mounted where shown on the wings and are served by a hoist 46, Figs. 9 and 13, running on a track 47 provided with rack teeth. The hoist 46, which runs in a passage extending from side to side within the wing, servesalso for loading the cabins through hatches in the wing and upper decks of the cabins. The craft is driven by seven direct-coupled propellers 6 mounted on the front of the horizontal portion of the wing. When cruising on the sea, the boat bodies are additionally braced to the wing by struts 11 which can be withdrawn into the wing until flush with the undersurface for flight. The struts are moved in guides 13, 31, Fig. 6, by rack-and-pinion gear 14, 16, the spindle of the pinion 16 being driven by a belt 24 from an electro-motor 12 mounted on the strut. Initial movement of the spindle projects or withdraws round-headed bolts 22 to engage or withdraw from recesses in the guide 13 at its lower end. Similar bolts engage the guide 31, being moved by a second belt 33 extending from the motor 12. The bolt shanks have helical slots engaged by pins on the spindles rotated by the belts 24, 33. The strut is secured in its raised position by a spring bolt engaging, the inboard end of the strut, withdrawal of the bolt completing the circuit to the motor 12. The navigation tops 59, Fig. 13, are each hinged to two struts 60, 61 which are movable together by electro-motors and worm gear, and in the extended position each top is engaged by a third strut 62. When collapsed, the struts and folded platforms of the tops lie flush with the wing which has watertight recesses to take them. Spring-urged flaps close the recesses when the struts are raised. The strut 60 may have an internal ladder and an external hoist operated by an electro-motor and endless cable, and encloses the electric cable and other connections. A disappearing gun is mounted at the top of each hull upon a transversely hinged section 54, Fig. 10, rotatable by an electro - motor thereon. These sections are situated just behind the pilot's cabin position. Fuel tanks for surface cruising are provided in the hulls and have compressed air means for jettisoning the fuel in an emergency. Fuel tanks for use during flight are provided in the wing.

Title: Device for operating air governing means on a refuse burning furnace
IPC: F23L9/00
Filed: 1975-01-09
Abstract: 1471401 Refuse burning furnace with air governing means GOTAVERKEN ANGTEKNIK AB 9 Jan 1975 [30 Jan 1974] 869/75 Heading F4B  A furnace for burning refuse (e.g. waste liquor produced when pulping wood) is supplied with preheated air through ports 11, Figs. 1 and 2, in its wall 10 from an air box 12 and conduit 13 with a throttling member (not shown). Each port 11 has an air flow governing means provided by a sleeve 14 which can be moved axially to adjust the amount of air which can flow between the tubes outer periphery and the edge of the port. The sleeve can also be moved axially to a greater extent so as to penetrate through the port and clean away deposits which accumulate on the port walls. As shown in Fig. 2 the sleeve is supported by a guide 24 which runs along a rod 25. There is a bellows 16 between the end of the sleeve and the air box wall. Four sleeves are interconnected by a yoke 29 for simultaneous movement by a single device. A forward and backward cleaning movement is caused by a piston-rod 26 and double acting piston 21 supplied with compressed air at 22 and 23. The air flow through a port 11 is determined by the position of its sleeve 14, i.e. normally by the rest position of the piston. To provide for adjustment of this rest position, the piston has a shaft 30, Fig. 3, which projects out of the air box 12. The end of shaft 30 bears against a stop provided by a screw 36. The stop is at one end of a tubular screw member 31. The member 31 is non- rotatably secured to the air box 12 but is axially movable. Adjustment of the position of the stop (and thus the rest position of the piston) adjusts the air flow through the port 11. The adjustment may be either (a) by turning the screw 36 by means of a knob 37 or (b) by axially moving the tubular member 31 by turning an axially-secured nut 32 by means of a rod 35 with a worm in mesh with a worm screw 34 on the nut. Rod 35 has other worms along its length for adjusting the air flow through other groups of air ports 11. Compressed air for the piston is governed by a valve 27, Fig. 1, and monitoring apparatus 28, which operates the pistons at predetermined intervals or operates the pistons of different groups of sleeves in turn. As shown in Fig. 1, a cover 19 has a cleaning opening 18 and an inspection window 20. A lamp 46 indicates when the sleeves 14 are in air-governing (rather than cleaning) positions.

Title: Process and apparatus for the recovery of gases or vapours taken up by adsorbents
IPC: B01D53/04
Filed: 1928-01-11
Abstract: 283,508. Naamlooze Vennootschap Norit-Vereeniging Verkoop Centrale. Jan. 11, 1927, [Convention date]. Gases, separating mixtures of.-Gas or vapour is expelled from an adsorbent by treatment with a gaseous displacing medium which is circulated in a closed circuit at a velocity higher than that used during the adsorption process. Fig. 1 shows a suitable apparatus for effecting this. A pair of adsorption chambers 1, 1 are supplied with the gas mixture to be purified through the pipes 3, the purified gas leaving at 5. To recover the adsorbed gas a displacing medium is used consisting either of the gas under treatment admitted by the pipe 8 or of another inert gas admitted by the pipe 40. The gas is forced by the pump 9 through a heater 14 into the adsorption chamber 1 which may be also heated by the steam coil 7. The resulting gas mixture passes into a cooler 27 where the recovered vapour is condensed and thence to a closed vessel 29 from which uncondensed gas is returned to the pump 9 and re-circulated. An automatic valve 39 admits sufficient fresh gas to the pump to compensate for losses. Heat exchange may be effected at 31 between the cold gas leaving the pump. and the hot mixture, leaving the adsorption chamber. When the adsorbent has been regenerated the heater 14 is cut out and the cold gas from the cooler 27 is passed directly via the pipe 45 to the adsorption chamber in order to cool the adsorbent. This action may be supplemented by passing cold water through the coil 7. In a modified arrangement the pump 9 occupies a position in the pipe 20, enabling the condensation of the recovered vapour to be effected under pressure. The Specification as open to inspection under Sect. 91 (3) (a) imposes no restriction on the velocity of the displacement gas and includes also the use, of a liquid displacement medium. It further describes facilitating tho separation of the adsorbent and the adsorbed substance by treatment with boiling water, or with a. liquid miscible with the adsorbed substance, or with a substance which wets the adsorbent better than the adsorbed substance. In a modification of this last feature the adsorbent is impregnated with a solution of a lyophile colloid and thoroughly dried. The adsorbing power is unimpaired while the adsorbent is dry, but by wetting the latter the adsorbed vapour is liberated. This subject-matter does not appear in the Specification as accepted.
