Abstract: 399,205. Screw propellers. HAMILTON STANDARD PROPELLER CO., 400, South Main Street, Hartford, Connecticut, U.S.A.-(Assignees of Caldwell, F. W.; 141, Longue Vue Drive, Mt. Lebanon, Pittsburg, U.S.A.) March 30, 1932, No. 9174. Convention date, April 21, 1931. [Class 114.] A variable-pitch screw propeller wherein the pitch is normally automatically controlled by centrifugal weights, is provided with a fluid pressure operated means for holding the blades in the minimum pitch position. Blades 2 have an inner sleeve 11 which is adapted to fit over a spigot 6 on the main hub 1. The sleeve projects at one side at 31 and is coupled by a lever 43 with a sleeve 51 encircling an extension of the propeller shaft. The blade roots have flanges 21 and opposed blades are held together by half sleeves 24 acting through thrust races 23. The bearing may be placed on the blade blank before the latter is pressed to shape. The sleeve 51 is coupled by levers 52 to pivoted arms 41 the ends B of which form the controlling weights. Movement of the weights results in movement of the sleeve 51 and thus in pitch adjustment of the blades. The sleeve carries lugs 55 adapted to contact with adjustable stops 58, 59 for determining the maximum and minimum pitch positions. On an extension of the hollow crank shaft is fitted a piston-like member 68 and this is in communication with passages 71 leading under valve control 85 to the lubricating pump 75 and the oil pressure system of the engine. On opening the correct valve the sleeve 51 is forced out and the blades are brought and held in the minimum pitch position. Instead of the restraining flanges 21 being integral with the blade roots, these may be separately fitted to sleeves screwed on to the blade roots. Bearing surfaces at the blade roots may be subjected to a nitrogenizing process. The hand control of the oil valve may be combined through a differential gear with a centrifugal governor control.

Filed: 1974-02-28
Abstract: 1457324 Shearing CANRON Inc 28 Feb 1974 [18 June 1973] 9220/74 Heading B3W A related rake angle and stroke control apparatus for a shear device comprises rake angle adjustment means, an adjustable stop for stroke adjustment, the applicable means adjacent the stroke adjustment means representing the interrelationship between the rake angle and stroke adjustment means and an indicator mounted on the adjustable stop for movement over the graphical means so as to indicate the extent of co-operation between the shear tools for any rake angle and any position of the adjustable stop. The rake angle of an upper, movable blade 54 is variable by pivoting a supporting ram 24 relative to a slide 23 vertically guided on the shear frame 21. The ram is pivoted by an actuating cylinder 27, the piston-rod- 28 bearing on an arcuate block 32 located in a circular opening 33 in the ram 24 and pivoted at 37 to the slide 23. A nut 34 on the rod 28 engages a,second arcuate block 31 which is freely rotatable in the opening 33. The ram is also connected to the slide by studs 38, 39 which allow the ram to pivot. The stroke of the ram is adjustable by means of stops 67, 68 adjustably mounted on a bracket 64 on the slide 23, the stop 68 ending the upward stroke when it engages a microswitch 71 on the frame 21 and the stop 67 ending the down stroke when it engages microswitch 72. To vary the stroke in relation to the selected rake angle, an indicator 74 on the stop 67 co-operates with markings on the bracket 64. Vertical lines 76 represent rake angle settings and sloping lines 79 representing workpiece lengths intersect lines 76, the intersections representing the lengths over which the blades are in shearing co-operation for a given rake angle. Indicia 77 on the lines 76 correspond to indicia 78 on rake angle control means. A cable 86, Fig. 4, couples a valve (83), Fig. 5, not shown, mounted on the ram 24 to a tensioning device 84 mounted on the slide 23. The mountings may be reversed and a pulley 96 adjacent the ram mounting accommodates tilting movement of the ram. The valve 83 is connected to the hydraulic ram-actuating cylinders 27. Tensioning the cable 86 by pivoting a lever 113 moves the valve body (89) to cause adjustment of the rake angle in one direction and a spring (91) in the valve. When the tension is relaxed causes adjustment in the opposite direction. Spring- biased detents (122) may be mounted between a collar 106 on which the lever 113 is mounted and a fixed collar 108 to facilitate indexing the lever 113.

Title: Improvements in or relating to a process for the mass copolymerization of styrene and maleic compounds
IPC: C08F22/00
Filed: 1951-04-24
Abstract: Styrene is copolymerized in mass with maleic anhydride or alkyl half esters of maleic acid, or mixtures of the anhydride and esters, by subjecting a mixture of monomers in which the mole ratio of styrene to the maleic is between 1:1 and 1.5:1 to free radical inducing conditions in the presence of 0.01 to 2 per cent. of 2, 5-ditertiary butyl parabenzoquinone.  Maleic acid alkyl half esters specified are the methyl ethyl, isopropyl, isobutyl, sec.-butyl, methyl isobutyl carbinyl and lauryl esters. Free radicle inducing conditions may be produced by the use of one or more of heat, actinic radiation, and catalysts such as benzoyl peroxide, diethyl peroxide, ditert.-butyl peroxide, ditert.-amyl peroxide, ditert.-butyl perbenzoate, diamyl disulphide, ditert.-dodecyl disulphide, and alpha, alpha1 azobisisobutyronitrile.  The polymerization is preferably carried out by heating first at 30 DEG  to 80 DEG  C. and then at 110 DEG  to 180 DEG  C. to complete the reaction, the 2, 5-ditertiary butyl parabenzoquinone being added to the reaction mixture either initially or after the reaction has started.  The copolymers are generally soluble in dilute aqueous solutions of alkali metal carbonates or hydroxides, or ammonia, and the resulting solutions may be used for sizing warp yarns.  The copolymers may also be dissolved in solvents and applied to fabrics, metal, and wood.

Abstract: 1381245 Pressure casting machines SANDERS ASSOCIATES Inc 27 Feb 1973 [2 March 1972] 9580/73 Heading B3F [Also in Division F1] In a circuit, Fig. 2, for controlling the rate of flow of fluid to a load 32 and the rate of change of flow, a main valve 21, of the type in which the flow to the load is proportional to the rate of flow of pilot fluid is controlled by an auxiliary valve 62 and a restrictor 64 which determines the maximum rate of flow of pilot fluid to the valve 21. A restrictor 69 determines the rate at which the valve 62 opens and thus the rate of change of flow of pilot fluid. In operation, the spool of valve 21 is initially displaced to the right of the position shown by pressure from a source 38 acting in a space 22. End space 23 is connected to reservoir through a throttle 71. This connects source 38 through conduit 37, valve 21 and conduit 33 to the rod end of cylinder 32 to retract the plunger. To move the plunger forwards a solenoid 58 is energized to connect a higher pressure source 51 to conduit 55. This pressure begins to open the valve 62 at a rate controlled by the adjustable throttle 69. This controls the rate at which pilot flow to the valve 21 increases and thus the rate of increase of flow to the load 32. After the piston has reached a steady speed, determined by the throttle 64, further acceleration may be produced by energizing a solenoid 57 and de-energizing 58. This connects the source 51 to a conduit 54, valve 82 and throttles 84, 89 which act as previously described. The cylinder 32 may be the shot cylinder of a die-casting machine.

Filed: 1925-04-14
Abstract: 243,224. Bombled, F., Bombled, P., and Bombled, L. April 14, 1925. Paper bags and the like, making.-The upper ply of a continuous flat tube formed by a templet B, Fig. 2, funnel C, and glueing-roller D is nicked by a rotating blade d to produce the tab d<1>, Figs. 1 and 9, and a rotating blade K co-operating with a fixed blade J then cuts the tube transversely, leaving only a narrow connecting- strip in the middle of the bottom ply. The cutter d, which coacts with a spring plate d<2>, Fig. 6, is carried by a lever b pivoted at c to a continuously rotating member a and controlled by a spring b<1>. As soon as the tab d<1> is cut, a projection e on the lever b strikes a fixed pin f, thus tilting the lever b so as to raise the cutter d clear of the paper. A spring g, Fig. 10, raises the tab d so as to prevent it from being cut by the blade J, and a spring h prevents the cut edge of the tube from being crumpled by the blade K. The primary diamond fold for the bottom of the bag is formed by a stationary member M, Figs. 2 and 11, co-operating with one of a number of rods k carried by a pair of belts or chains N, the interior of the paper tube being meanwhile engaged by a fixed rod H which projects from the templet B and registers with gaps formed in the cutting-blades J, K. Glue is applied to the bag bottom by a pad l on a roller O carrying a pair of belts Q, Figs. 2 and 12, the speed of the coacting rollers O, P being sufficient to detach the bag from the rest of the paper tube. The forwardly-projecting part of the bag bottom is turned back by a fixed folder R, Fig. 12, and a rotating folder S, Fig. 2, then completes the folding by pushing the bag between the rollers P, T. Quickly rotating coacting rollers Y, U discharge the bag to a shoot V, whence it drops upon a conveyer X. When the machine is used for making lined bags, the inner paper strip E and the outer one A are stuck together by dabs of glue applied by a roller F. The two strips A, E are relatively offset so that the seams of the lining and of the bag do not come opposite one another.
