IPC: B65D1/26
Filed: 1965-05-06
Abstract: 1,111,823. Sheet forming. ILLINOIS TOOL WORK Inc. 6 May, 1965 [8 May, 1964], No. 51641/67. Divided out of 1,111,821. Heading B5A. A container having a beaded lip is made by plunger assist blow forming a peripherally clamped heat-softened sheet between male and female dies, the upper peripheral region of the drawn part of the article being clamped between surfaces 86 and 106, on the male and female dies respectively, upon full penetration of the male die. The region 132 of the sheet located between the two clamped portions is subsequently severed between surfaces 136 and 138 by further downward movement of the male die, under the action of its internal stresses, said region 132 contracts to form a beaded lip 134.

Abstract: 1,091,622. Haymaking machines. R. B. CUNNINGHAM, R. A. CUNNINGHAM and T. W. CUNNINGHAM. Dec. 6, 1965 [Dec. 4, 1964], No. 51715/65. Heading A1F. A tedder comprises a draft frame 10 carrying a rotor-assembly consisting of a horizontal shaft extending transverse to the direction of travel, tines T being distributed along the shaft, which is rotated so that the tines move upwardly and rearwardly from their lowermost position, but non-uniformly, the tines being alternately rotated and retarded so that during their retarded phase the tines pick up cropmaterial, owing to their forward bodily travel, which material they shed during their subsequent rapid rotation. Each tine is S-shaped and is clamped to the shaft at its mid-point. The shaft is surrounded by a . sleeve 102 comprising two semi-cylindrical portions fitting together to leave slots through which the tines protrude. Two fixed rods 26, 28 extend parallel to, but above, the rotor and these rods may carry a series of wire crop-strippers 160 extending between adjacent tines. The frame 10 is carried by two wheels, one of which 40 rotates idly while the other, 38, drives the rotor-shaft through gearing. The gearing may comprise either a series of elliptical gears or mutilated gears. If elliptical gears are used, the tines are alternatively accelerated and retarded, but with mutilated gearing the tines' rotation is arrested during part of their cycle. The wheel 38 can be disconnected from the drive-shaft, for transport, so that the tines are not then driven.

Title: Improvements in and relating to air pre-heating vapor generators
IPC: F23M20/00
Filed: 1965-12-09
Abstract: 1,093,569. Regulating gas outlet temperatures; forced flow steam generators; tube supports. COMBUSTION ENGINEERING Inc. Dec. 9, 1965 [Dec. 29, 1964], No. 52398/65. Headings F4A, F4B and F4S. Combustion air supplied by fan 28 to gas, liquid, or pulverized fuel fired furnace 10 is pre-heated by passing transversely over sinuous tubular heat exchangers 30, 32 in air supply duct 26. The heat exchangers 30, 32 are connected in a closed circuit with tubular heat exchanger 46 in exhaust gas duct 18 and a heat transfer fluid, such as water, biphenyl or arclor is forced by pump 38 round the circuit to cool the exhaust gas and heat the combustion air, the degree of cooling of the exhaust gas being controlled under the influence of a temperature responsive device 54 to prevent the outlet gas temperature falling below its dew point. Device 54 regulates a valve 56 in by-pass 58 around the heat exchanger 46. The ratios of the surfaces of the gas exhaust and air pre-heat heat exchangers are such that at maximum continuous rating of the vapour generator fluid leaving the former and entering the latter is midway between the temperature of combustion gas entering the former and air leaving the latter, whilst fluid leaving the latter and entering the former is midway between the temperature of combustion gas leaving the former and air entering the latter. In a modification applied to forced circulation vapour generators (Fig. 4, not shown) part of the water to be evaporated from drum 20 supplied by pump 74 is diverted through line 78 to the air heating tubular heat exchangers 30, 32 and then to the heat exchanger 46 in the exhaust gas duct before flowing through the evaporating tubes, the amount so diverted being regulated by valves 82 again under the control of temperature regulator 54. The tubular air heaters are supported by rods (62, Fig. 3) from a structural member 64 which is in turn supported from member (68) by rods (70) extending through bellows seals (72).

Title: Spool seizure output bypass valve

IPC: F15B18/00
Filed: 1966-11-24
Abstract: 1,146,148. Valves. BELL AEROSPACE CORP. 24 Nov., 1966. No. 52552/66. Heading F2V. A control valve, responsive to control signals from a valve 50 and used to actuate a load 10, comprises two identical valves 40 and 40<SP>1</SP> arranged in tandem and within the same housing 41. Valve 40 comprises a sleeve 42 slidable within the bore of the housing and a valve spool 43 slidable within the sleeve, a spring-loaded locking device 52, 53 tending to maintain the sleeve fixed with respect to the housing. Valve 40<SP>1</SP> is of similar construction with like parts being indicated by the same, but primed reference numerals. Upon the spool 43 of valve 40 moving to one side of the position shown, fluid under pressure, from source P 1 , is conducted through lines 21 or 22 to a piston 13 thereby actuating it and the load 10 attached thereto. Should, however, the spool become adhered to the sleeve, as due to foreign matter becoming wedged between these two members, then the actuating signals, applied to the spool, act on the spool and force it, and the surrounding sleeve, to move in unison. Upon such translation, either one of by-pass ducts 46 or 47, normally closed by the sleeve, is brought into communication with both ducts 21, 22, thereby equalizing forces acting on the piston 13 and so rendering it non-responsive to further actuating signals. Thus, for example, if the spool and sleeve move to the left, communication is made between the lines 22 and 21 along the path 22, 48, 46, 44 and 21. Similarly for valve 40<SP>1</SP>. If, however, seizure occurs in only one of the two valves 40 and 40<SP>1</SP> then the other remains effective in actuating the load 10. Figs. 2 and 3 (not shown) indicate an alternative form of locking device and by-pass duct arrangement respectively, the latter comprising a suitably apertured valve spool slidably mounted on a similarly apertured shaft, there being no movable sleeve.

Abstract: 1,164,629. Moulding combustion elements. AMERICAN THERMOCATALYTIC CORP. 25 Nov., 1966 [3 Feb., 1966], No. 52971/66. Heading B5A. [Also in Divisions C7 and F4] A combustion element capable of promoting the substantially flameless infra-red radiation generating combustion of gases flowing therethrough comprises a gas-permeable ceramic mat of amorphous fibres in combination with powdered, metallic aluminium in amount from 20 to 80% by weight of the ceramic material. The mat may be formed on a foraminous support with said fibres of silica-alumina, and alumina also present. The element may be formed in the following manner. A gallon of gel is made using 1À0 grams of colloidal alumina and 78À9 grams of aluminium nitrate-9 hydrate per gallon of water. To form a slurry 8À5 grams of ceramic pre-chopped fibres are then added together with, after a suitable time lapse and agitation, 93À5 grams of methyl methacrylate and 6À5 grams of powdered aluminium. A foraminous support is then inserted in the slurry and connected to a source of vacuum to cause accretion of solids thereon. A layer  inch thick is accreted and the element then dried for a sufficient time to vaporize all the methyl methacrylate. In a further method of forming the element a layer 0À275 inch thick is accreted on the support from a slurry not containing the powdered aluminium. The element is then dusted with the aluminium powder. The slurry may alternatively be prepared using 120 grams of colloidal alumina, 78À9 grams of Al(NO 3 ) 3 - 9H 2 O, 8À5 grams of fibres and 93.5 grams of methyl methacrylate. To 800 ml. of this was added 0À1% by weight of aluminium. The elements were then formed by accretion of a support.
