Title: Ship's hatch cover assembly
Inventor: GREER EDWARD M
IPC: B63B19/26
Filed: 1957-06-24
Abstract: 825,108. Door-operating appliances. G. M. E. CORPORATION. June 24. 1957, No. 19847/57. Class 65(1) [Also in Group XXXIII] A hatch-cover assembly comprises, for example, a pair of pivotally connected cover panels A and B, Fig. 11. pivotally mounted to an upright standard 35 adjacent the end of the hatchway 22: Gasket 41, Fig. 9, mounted on the periphery of the panels engages sealing rails 26 on each side of the hatchway 22: Actuation of the hydraulic units 67, 68 exerts an upward component of force on hinge pin 65, of the reaction member 61, positioned below a line joining the pivotal mount 32 to the point of engagement of the roller 81, with the tracks 82, and constrains the roller to mount the inclined face of an abutment 91, thus disengaging the gasket from the sealing rails. With continued upward movement of hinge pin 65 the panels A and B tend to fold together and the rollers 81 ride down the abutment 91; at such time the panels are inclined from the horizontal and the peripheries of the rollers 81 extend sufficiently beyond the edge of the panel B to ensure that the gasket 41 does not engage the rail 26 during the remainder of the movement of the panels. A sealing abutment 51 affixed to the rail 26 has a surface inclined at preferably the same inclination as the abutment 91 to engage the lower edge of the gasket 41. In the event of an adjacent panel C being provided, gaskets 41f and 41d are mounted for engagement as shown in Fig. 4. Further embodiments describe an arrangement whereby two pairs of panels hinged together at 124, Fig. 16. are opened by first actuating the hydraulic units of panels Y-1 and Y-2 thus folding these panels to bring a roller 133 mounted on the panel Y-2 into engagement with the track 134 to lift panels X-1 and X-2. In Figs. 17 and 18 (not shown). an additional roller may be provided on panel X-2 and arranged to ride on a track positioned inwardly of the track 134' to facilitate initial operation of either pair of panels, thus when the hydraulic units associated with panels X-1 and X-2 are actuated, the additional roller rides out of a depression and up the inclined surface of an abutment thereby breaking the seal adjacent hinge 124. As the panels Y-2 and Y-1 are dragged to the left, the rollers 138 will move out of depressions (not shown) to raise the edge 136 of panel Y-1. The abutment 91 may be replaced by a roller engaging an arm with an inclined surface. Specification 690,924 is referred to.
Patent GB-1181786-A (GB)
Title: Process for making Flat Oriented Film of Polymeric Material
Inventor: SMEDT FELIX FREDERICK DE
IPC: B29C35/02
Filed: 1966-05-05
Abstract: 1,181,786. Biaxially stretching films. GEVAERT-AGFA N.V. 11 April, 1967 [5 May, 1966], No. 19887/66. Heading B5B. In the production of lay flat films of orientable organic polymers, such as polyethylene terephthalate, wherein the film is biaxially stretched, after the film has been stretched transversely, the margins of the film are heated to a temperature between the temperature at which it has been longitudinally stretched and the melting temperature of the polymer. The film may be heat-set after the heating of the film margins. The heating of the film margins may be effected in such a manner that the extent to which the film margins are heated is at a maximum at the outer edges of the film and decreases inwardly from the edges. As shown in Fig, 2, which is a cross-section of the zone in which the film margins are heated, an infra-red radiator 21 parallel with the film edge and extending along the length of the film is located at each side of the film 9. The radiator comprises a tubular elongate radiation source 22 which is heated electrically and a reflector 23, both located in a metal housing 24. Each housing 24 is provided at the side facing the film with an elongated slotlike mouth which is defined by the lips 25 and 26. The marginal portion of the film is caused to travel centrally between the lips. The temperature of the heater 22 may be about 120‹ C. and the passage of the film through the film margins heating zone causes the wrinkling of the film margins to disappear. This wrinkling of the margins occurs during the biaxial stretching of the film and is due to the marginal portions of the film having become more elongated than the remainder of the film. The difficulty which is otherwise apt to occur in the heat-setting zone due to the jaws of the film margin grippers in the heat setting zone not opening widely enough to receive puckered or wrinkled film margins is thereby obviated. The proper winding up of the film on storage rolls is also facilitated.

Title: Improvements in electric furnaces
IPC: H05B6/56
Filed: 1919-08-14
Abstract: 153,951. Campbell, D. F. Aug. 14, 1919. Electrode furnaces.-An electrode furnace suitable for melting non-ferrous metals is arranged so that it can be heated at will either by an arc between the electrodes or by the resistance of a layer of material such as pitch or petroleum coke, into contact with which the electrodes are tilted. The electrode supports may be readily detachable from, or independent of, the furnace body. In one arrangement, two rockers 3, Fig. 1, resting on rollers 5 are secured by bolts or cotters to water-cooled end plates 8 of cast bronze. Three open slots in each of these plates receive supporting-studs 11 on the furnace body proper, which can thus be removed and substituted by other bodies for treating different charges with the same electrodes. Centrally situated with regard to the rocker is a partly-spherical socket in each end plate 8, receiving a similarly-shaped bronze block 12 through which an electrode slides. An insulating cap 14 separates the block 12 from the socket. Two rods 13 attached to the block 12 guide the electrode-holder, and are acted on by springs to press the block closely into the socket. At their outer ends the rods 13 pass through a frame 22, 23, pivoted to the end plate 8 by pins 24 level with the axis of the block 12. The frame 22, 23, and with it the electrode, are tilted by means of a link 20 forked at its upper end and pivoted at its lower end to a nut 19 on a screw shaft 15 extending below the furnace so as to actuate both frames. The shaft 15 is turned by means of a chain 17 and a hand-wheel. Attached to the electrode-holder is an insulated nut 29 on a screw shaft which is driven by bevel gear and a handwheel 33 mounted in the tilting frame 22. A flexible shaft 36 connects the bevel gears of the two electrodes. A roller 35 supports the outer end of the electrode. In another arrangement, the partly-spherical block 43, Fig. 4, is attached to a single guide 42 for the electrode-holder 41. The guide 42 is pivoted to a cap 54 on a vertical screw 56, the nut 60 of which is supported by a pillar and rotated by a worm and hand-wheel. Screw and bevel gear 51 and a hand-wheel 52 for axial adjustment are mounted in the guide 42. The furnaces may be modified for polyphase currents.

Abstract: 788,722. Ornamenting. GENERAL ELECTRIC CO., Ltd., HILL, R. T. J., and WARREN, G. W. July 22, 1954 [July 22, 1953], No. 20370/53. Class 93 [Also in Group XL(a)] In the manufacture of a screen, particularly a a fluorescent screen of a C.R.T., of the kind in which two, three or four different powdered materials are applied in intercalated sets of strips on the surface of the base of the screen which is formed with a series of grooves, one of the materials is first applied to the whole of the surface and the material is thereafter removed from the upper parts of the ridges formed between the grooves, and at least one other of the materials is applied to the exposed tops and/or one or both sides of the ridges by a method which does not result in the application of the other material or materials to the already coated bottom parts of the grooves. In the particular method described the grooved glass plate 1 forming the screen or the end wall of a C.R.T. is immersed in a settling medium containing a green-fluorescing phosphor, e.g. willemite, and the phosphor G is allowed to settle on the plate. The plate is then removed and the top parts of the ridges. 3 cleaned by wiping the phosphor off these parts, Fig. 1. The plate is then immersed, with its plane highly inclined to the horizontal and with the grooves 2 extending horizontally, Fig. 2, in a settling medium containing a red-fluorescing phosphor, e.g. Zn Cd S activated by Ag, and the phosphor R is allowed to settle on parts of the uppermost sides 4 of the ridges 3, the already-coated bottom parts of the grooves 2 being protected from above by the projecting ridges 3. The plate 1 is then reversed and immersed in a settling medium containing a blue-fluorescing phosphor, e.g. ZnS activated by Ag, so as 'to coat the other sides 5 of the ridges 3 with phosphor B. The plate is then removed and the apices of the ridges 3 cleaned, after which a coating of conducting material S, such as silver paint, is applied to the apices by painting or lightly rolling over them a rubber pad soaked in the material, Fig. 3. Alternatively after the first material has been applied to the screen and the upper portions of the ridges cleaned a second material can be applied to the upper portions by coating them with a suspension in a volatile medium by painting or by rolling over the portions a pad impregnated with the suspension. Corresponding ends of the conducting strips S can be connected together by painting conducting connecting strips along the sides of the plate transverse to the strips S. and in electrical contact with them.
