Title: Protective covering for metal articles and method of applying
IPC: C09D101/28
Filed: 1944-05-31
Abstract: Metal articles are protected during shipment, handling or storage, by applying to each article a molten composition comprising ethyl cellulose (45.5 to 50 per cent ethoxyl, 7 to 200 centipoises viscosity), and for every 100 parts of ethyl cellulose, 25 to 150 parts of a solvent plasticiser, 25 to 375 parts of a non-solvent exuding-type plasticiser, and 0 to 50 parts of a thermoplastic resin, the total amount of plasticiser being between 100 and 400 parts for every 100 parts of ethyl cellulose. The amount of composition applied to each article is sufficient to provide a continuous impervious covering over the article.  The composition is readily removed from the article by stripping after cutting through the covering, or by cooling and then fracturing the covering by striking it.  Stripping is facilitated by inserting during application a string or strip in the covering and pulling at the time of stripping.  The covering does not adhere to the metal article and leaves the surface clean when stripped.  The composition may be applied to tools, machine parts, gears, or pistons, of iron, steel or other corrodible metal.  The viscosity characteristic of the ethyl cellulose is taken as the viscosity of a 5 per cent solution in a solvent mixture consisting of 80 per cent toluene and 20 per cent alcohol at 25 DEG  C.  The solvent plasticiser may be dibutyl phthalate, methyl abietate, hydrogenated ethyl abietate, tricresyl phosphate, tributyl phosphate, butyl stearate, or methyl phthalyl methyl glycollate, or it may be a wax which is a solvent for the ethyl cellulose such as montan wax, spermaceti, stearic acid, beeswax, Japan wax, hydrogenated castor oil, or candelilla wax.  The non-solvent exuding-type plasticiser may be a vegetable oil, a mineral oil, or a wax which is a non-solvent for ethyl cellulose.  It may be corn oil, castor oil, acetylated castor oil, coconut oil, cottonseed oil, soya bean oil, linseed oil, or perilla oil, or it may be a light or heavy mineral oil or refined mineral oil.  Paraffin wax, petroleum wax, ceresin, and Chinese insect wax, are specified non-solvent waxes.  The composition may contain an addition of lanolin.  The resin may be an ester of rosin with glycerol, pentaerythritol, or a higher polyhydric alcohol; hydrogenated rosin, polymerized rosin, or heat-treated rosin; an alkyd resin modified by a rosin ester; an oil-modified alkyd resin; a maleic-modified rosin-polyhydric alcohol ester; a rosin-modified phenol-formaldehyde resin, an unmodified phenolic resin, or a coumaroneindene resin.  The composition may contain a small amount of a stabilizer for the cellulose ether, e.g. diphenylamine, phenyl beta naphthyl-amine, carbazole, diphenylguanidine, sym.-dibetanaphthyl paraphenylene diamine, hydroquinone benzyl ether, copper naphthenate, cupric chloride, or cupric acetate.  Prior to coating with the molten ethyl cellulose composition, the metal article may be lightly coated with oil.

Title: Controlling system for means for adjusting speeds of freight cars in a yard
IPC: B61J3/12
Filed: 1970-03-05
Abstract: 1280626 Adjusting freight-car speeds by mobile retarder HITACHI Ltd and JAPANESE NATIONAL RAILWAYS 5 March 1970 [10 March 1969] 10724/70 Heading F2E Between the rails of each of a number of sorting tracks 14a, &c., Fig. 1, in a marshalling yard, is located a mobile retarder e.g. 18a consisting of a driving device 26, Fig. 2a, and a pushing or engaging device 28, on wheels 30 to 32<SP>1</SP> and 42 to 44<SP>1</SP> respectively, running between rails 24, 24<SP>1</SP>. The driving device in turn consists of a driving motor unit, preferably a linear induction motor, and a control unit. Part of the control unit consists of detectors 38, 40, to detect the wheels of a freight car. The output from detector 38 passes in part to an arm controller 60 (see below) and partly to a timer 62, the output from which is fed to a controller 64 which controls the retarder motor; the output from detector 40 is fed to the controller 64. In operation, the retarder is initially at rest. When a freight car proceeds into the sorting track, detector 38 detects one of its first wheels, whereupon timer 62 is started, and arm controller 60 is actuated. In consequence two arms carrying rollers 48, 48<SP>1</SP>, Fig. 2b, are hydraulically extended into the paths of the two wheels on the leading axle. When one of the first wheels reaches detector 40, controller 60 is actuated whereby the retarder starts and accelerates at a predetermined value of acceleration. The duration of acceleration is equal to the predetermined time limit T of the timer 62 diminished by the time taken for the car wheel to travel from detector 38 to detector 40. Thus, the greater the speed of the freight car, the greater the duration of acceleration. At the end of time T, the output from the timer to controller 64 provides an instruction for the retarder to begin coasting or braking. The freight car advances relatively to the retarder until the first wheels reach the rollers 48, 48<SP>1</SP>; thereupon further rollers 46, 461, on arms 50, 50<SP>1</SP> respectively, Figs. 2a, 2c, are extended behind these first wheels so the wheels are held. Next, the retarder is further decelerated to a predetermined speed, e.g. 5 km./h., and thereafter drives positively to "inch" the freight car to the location where it is to be released from the retarder; at this place the rollers 46 &c. are retracted and the retarder is quickly braked, optionally by reversing the phase rotation of the 3-phase voltage supplied to its linear induction motor. Finally the retarder moves backwards at full speed to a position where it awaits the arrival of the next freight car. Two or more coupled frieght cars may be dealt with during a single cycle of operation by a retarder.

Title: Photographic shutters
IPC: G03B9/22
Filed: 1931-04-13
Abstract: 361,251. Photographic shutters. BAR•NYI, A., 12, Ringstrasse, Lichterfelde, Berlin. April 13, 1931, No. 10788. Convention date, May 20, 1930. [Class 98 (i).] In photographic shutters, particularly of the pivoted-blade, symmetrically-driving type, the motor or master member actuating the blades is controlled by a retarding mechanism annected thereto through a coupling member which is rendered inoperative after the desired period of time. Undue wear is thereby avoided. As shown, the motor member comprises a spring housing furnished with lugs 3 adapted to engage the tail 2 of a lever 1 which carries a sector 4 meshing with a sector 5 adapted to drive a sector 7 meshing with a gear 13 of the escapement retarding mechanism 14. Both sectors 5, 7 are mounted upon a stud 6, the sector 5 carrying a lug 10 adapted to drive the sector 7 through a cranked pawl 9 normally held in operative position against a pin 8 by a spring 15. Disengagement of the pawl is effected by contact of the arm 91 with a pin 12 carried by a cranked lever 11 furnished with a pin 17 engaging a cam slot 18 in an annular setting member 20. By moving the member 20 anticlockwise the pin 17 moves along the cam portion of the slot 18 and brings the pin 12 nearer the arm 91 thereby reducing the time of exposure; when the pin 17 reaches the concentric portion of the slot 18 the pin 12 is so set that the pawl 9 is immediately tripped. By still further movement of the member 20 the lever 1 is rocked by a cam 20 engaging a pin 21 so as to remove the tail 2 from the path of the lugs 3 and still further shorten the exposure.

Title: Improved crusher
IPC: B02C2/06
Filed: 1946-04-08
Abstract: 610,492. Gyratory crushers. TRAYLOR, S. W. April 8, 1946, Nos. 10798 and 10799. Convention dates, April 23, 1945, and Jan. 24, 1946. [Class 59] In a crusher of the kind wherein the material is crushed between a stationary ring 31 and a gyratory head 36, a floating ring 43 is interposed to provide two upwardly enlarging crushing spaces. The ring normally tends to move with the head and most of the crushing is done on the outside of the ring. The face 44 of the ring may be conical, but as shown in Fig. 3, it is concave, the face 45 being convex. When the crusher is running empty or lightly, the ring 43 has a tendency to cock and jam the mill. To avoid this, the securing nut 40 has radial lugs 56 overhanging the ring, and additionally or alternatively lugs 57 may be provided on the mantle 39 of the head 36. Cocking is minimized if the material is fed into the inner crushing space and allowed to overflow into the outer crushing space. To effect this, the feed hopper is provided with a ledge 54 overlying the outer space. In a modification, anti-cocking lugs project in wardly from the floating ring and bear on the mantle 39. In the construction shown in Fig. 7, the floating ring 64 is joined by radial arms 65 to a collar 63 which fits loosely in an annular channel 62 in the head.

[Class 75(i)] [Also in Groups XXVI and XXIX] In a device for regulating a pump supplying fuel to the burners of a jet propulsion turbine comprising a fluid-operated piston and cylinder in which the ends of the cylinder are in communication through a restricted orifice and one end has a valve controlled vent, a spring being provided in the vented end for urging the piston to the position for increasing pump output and the piston being moved in the opposite direction by the output pressure of the pump, the vent controlling means comprises a variable choke through which the pump outlet passes, means responsive to the pressure difference for actuating the vent valve, and means responsive to blower air pressure for adjusting the choke. Liquid fuel from the pump flows through a housing from an inlet 2, through an orifice 8, to an outlet 3, the orifice being adjustable in position by a capsule 14 responsive to blower air pressure. The pressures upstream and downstream of the choke are applied to a diaphragm 30 to operate a lever 25 and so actuate a valve 24 controlling the vent from the pump regulating cylinder. The piston of the regulating device controls the swash plate, &c. of the pump. The loading spring 28 of valve 24 may be thermally variable and so give a temperature control. In a modification, the choke is adjusted by the capsule 14 through a relay in which the stem of a piston actuating the choke constitutes a moving seat for a controlling valve carried by the capsule. A resilient connection may be provided between the choke and its actuating stem, and the choke may be adjusted by hand. A damping action on the capsule is provided by admitting liquid to the capsule chamber under the control of a float valve. A non-return valve prevents the entrance of liquid into the air pipe.
