Title: Sheet feeding and stacking apparatus
IPC: B65H29/60
Filed: 1971-05-27
Abstract: 1354616 Delivering sheets EASTMAN KODAK CO 27 May 1971 [1 June 1970] 17620/71 Heading B8R Articles of sheet form, e.g. having a comparatively rigid rectangular position 11, Fig. 1A, and a limp pull tab 12 with a perforation 13, are delivered, e.g. by cutting from a web, between two belts 16, 16a, Fig. 2A, engaging the portion 11 only, which move at a speed to produce gaps between the articles. As each article leaves the belts on to a path comprising horizontal tables 30, 31, 32, Figs. 2A and 2B, and passing over a plurality of stacking receptacles 26, 27, 28 to a reject receptacle 29, its trailing end is engaged by one of a plurality of pairs of pins 24 carried on endless roller chains, the pins reaching into grooves 37 in the tables so as to positively engage and feed each article. Before each receptacle 26, 27, 28, the article path is formed by a diverter 33, (34, 35) which in its upper inoperative position is co-planar with the tables and in its lower position is slightly inclined to direct an article into the receptacle. The path of the pin chains follows the slope of an operative diverter to ensure continued engagement of a diverted article, while grooves 37 in the diverter allow passing of the pins even in the raised position. At the trailing end of each receptacle, the chains have an upwardly sloping movement imparted by idler sprockets 160, so that the pins rise sufficiently to disengage a diverted article before its leading end is forced against a container wall. The diverters are controlled by a programming control means through solenoids or hydraulic cylinders 47. The pins are each pivoted to the chains and kept perpendicular thereto under the control of an arm carrying a roller running in a cam track in a path 68<SP>1</SP> in a frame member 21. Each receptacle is lifted into receiving position by a table 72, or manually, so as to be placed between trailing and leading walls 74,75, and so as to be slanting as in Fig. 9, and has a spindle 71 projecting from the bottom wall at an angle of 35 degrees to the vertical to receive the perforations 13. When an article comes over a receptacle, it is supported on a rotating blade member 80, Figs. 1A and 12, cut away in two regions 82 to be formed into two sections 85. As the trailing end comes over the receptacle, the blade section moves from under it and it is forced downwards, and sideways by the spindle 71, while the next article is supported by the other blade section. The tabs 12 are supported on rods 23 parallel to the belt 16, on raised ribs 40 of the diverters, and may also be supported by a further and smaller blade member 88 which releases it at the same moment as the portion 11 is released. Blades 100, 101 may be projected over the receptacle but under the blade member 80 to collect a few articles and withdrawn to drop the group of articles on to the spindle 71. Articles are stacked in batches in receptacles 26, 27, using one while the other is emptied, sample articles are diverted to a simple receptacle 28, and rejects to a receptacle 29.

Patent GB-375989-A (GB)
Title: Improvements in or relating to tubular heat interchanging means such as feed water heaters and the like
IPC: F22D1/32
Filed: 1931-06-19
Abstract: 375,989. Headers for heat exchangers; heating water. SWALLOW, M. G. S., Drewton, Park Road, and PETTY, T., Dormin, Greta Avenue, both in West Hartlepool, Co. Durham. June 19, 1931, No. 17817. [Classes 64 (i) and 64 (iii).] In a tubular heat exchanger such as a high-pressure feedwater heater the header is formed by the attachment of a simple cover 19 to a tube-plate 2 furnished with an inlet and outlet 5, 6, and a partitioned pass director 18 is enclosed between the cover and the plate to connect up the ends of the heat exchange tubes as desired. As this director 18 forms no part of the tube-plate and is not exposed to the full pressure differences in the apparatus it can be a light casting of cheap metal. The pass director shown in Figs. 8, 9, and 10 covers the inlet 6 in the tube plate and its partitions connect this inlet to the inlet ends of the first pass in the heater. Partitioned spaces in the director 18 also connect the ends of intermediate passes and the outlets of the final passes are left open so that the escaping medium passes out through the open outlet 5. Tubes consisting of a number of straight portions connected by return bends may be used as in Figs. 15 and 16, the pass director in this case simply consisting of a portion 18b connected to the-inlet by a branch 18a and covering the inlets 17 to the tubes, the outlets 12 being left open. An annular pass director may also be used covering the ends 12 and not the ends 17. The tube bends are obtained by welding on U-shaped castings provided with removable plugs to aid cleaning and inspection. A pass director suitable for Field tube apparatus or U-tube constructions in which one arm of the tube is prolonged into the header is shown in Fig. 29. A fitting for byepassing the heater if a tube bursts is shown in Figs. 35 and 38. Normally water enters inlet 47, passes through valve 46, and through connection 48 to the heater, leaving through passage 49, valve 50, and connection 51. Water leaking through port 59 maintains the pressures below and above piston 54 equal so that spring 96 may maintain it against seat 56 and close the byepass. If a tube bursts the water level in the heating steam condensate outlet 63 rises and actuates a diaphragm 65, or a piston, bellows, or float, which operates a valve 66 to release the pressure below piston 54 so that it is driven down closing valve 46 and opening byepass 60. A weighted lever 86 holds valve 66 permanently open once the control has operated or alternatively the same result is attained by a spring trip action.

Abstract: 545,709. Electrical insulating tape ; polyvinyl acetal resin compositions. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 19, 1940, No. 17864. Convention date, Dec. 19, 1939. [Class 2 (iii)] [Also in Groups VIII and XXXVI] A flexible extensible electrically insulating tape comprises a polyvinyl acetal resin admixed with from 30 to 50 per cent. by weight of monomeric methyl methacrylate. The resin may comprise the formaldehyde-, acetaldehyde-, or butyaldehyde-condensation product of a partially or completely hydrolysed polyvinyl ester such as polyvinyl acetate, or mixtures thereof. The methacrylate may be compounded with the resin before it is made up into a tape by moistening the resin with the monomer and milling or rolling, the sheet being then cut or extruded into tape form ; alternatively, the resin may be formed into a tape and then soaked in the monomer. The tape may take the form of a fibrous backing of glass, cotton or other fabric coated or impregnated with the mixture of resin and methacrylate. After the tape has been applied to the electrical apparatus, e.g., a form wound coil of rectangular conductors suitable for a high-voltage generator, it is heated, with or without pressure, to polymerize the methacrylate and to convert the tape into a hard rigid insulation shrunk onto the underlying structure; prior to heating, a binding of linen tape or a layer of aluminium foil covered with vulcanized rubber tape applied under tension may be applied over the insulating tape. Specification 351,082 is referred to.
