Title: Improvements in master cylinders for hydraulic transmission systems
IPC: B60T11/22
Filed: 1933-01-24
Abstract: 414,047. Hydraulic transmission of power. HYDRAULIC BRAKE CO., 84, West Hancock Avenue, Detroit, Michigan, U.S.A. Jan. 24, 1933. No. 2277. Convention date, Jan. 25, 1932. [Class 69 (ii).] The master piston of an hydraulic brake or other hydraulic transmission system has an aperture therethrough which is normally open to give free communication between the master cylinder and the reservoir and is closed during the application of the brakes &c., by a member through which the pressure is applied. The master piston 26 and cup-washer 33 have an aperture 34 and a member 27 is disposed within the piston, in which seats the piston-rod 13. The rod 13 is normally held in raised position by the spring 18 and the members 27, 28 are urged apart by the spring 28 so that there is a free passage between the cylinder and the reservoir 11 through the passages 34, 35. When the brakes are applied the member 27 is first moved downwardly until a flange 30 abuts on the piston as shown in Fig. 3 so that the lower face of the member 27 is flush with that of the piston and closes the aperture 34. A pair of oppositely acting non-return valves 41,43 of which the valve 41 is seated by the spring 39 serve to retain a minimum pressure in the pipe lines 45. The reservoir 11 is mounted on the master cylinder and has a corrugated flexible part 10 to permit the slight swinging movement of the rod 13 due to its conviction with the operating lever.

Title: Improvements in dolls and the like
IPC: A63H3/40
Filed: 1923-01-25
Abstract: 214,722. Munyard, A. R. Jan. 25, 1923. Dolls. - A doll is provided with mechanism which produces changes of facial expression when the doll is picked up and rocked. The mechanism is supported by a base 1, Fig. 1, mounted on a seating 8 within the head, and comprises two pendulums 11, 27. The pendulum 11 swings about a wire 14. and the upper end of its rod 12 engages teeth 17 formed on the sides of a rackbar 16 which slides through supports 20. A pawl 21, Fig. 2, is pressed into engagement with the teeth by a spring 24 and retains the bar 16 when it has been moved by the rod 12. The pendulum 27 swings about a wire 26, and the upper end 30 of its rod 28 is engaged by a spring-pressed pawl 36 which extends through a slot 18 in the bar 16. The face of the doll is made of rubber or similarelastic substance, or of a rubber covering on a base of harder substance. The eyelids 47, 48 and the eyeballs 49 are movable, and tear drops 54 of glass are fitted in recesses in the eye sockets. The eyebrows, lips, cheeks, and tears are connected by cords 70 to the rack-bar 16, and the eyelids are connected by cords 75 with the rod of the pendulum 27. A cord 79, Fig. 2. also connects the upper end of the pendulum-rod 12 with the pivots of one of the legs of the doll, or to a lever operated by a push button. When the parts of the mechanism are in their normal position, the face has a fretful expression. By rocking the doll, the pendulum 11 moves the rackbar 16 gradually, thus raising the eyebrows, withdrawing the tears and causing the lips to part. The bar 16, when it reaches the end of its travel.. pushes back the pawl 36 and releases the pendulum 27 the movement of which causes the eyelids to open and close. By laying the doll on its right side, or by moving the legs and therefore the cord 79, the upper end of the pendulum rod 12 engages a stop 22, Fig. 2, on the pawl 21 and releases the rack, and the face then resumes its fretful expression.

Abstract: 742,064. Mounting and controlling liquid fuel burners. SWINNEY BROS., Ltd. Jan. 28, 1954 [Jan. 28, 1953], No. 2473/53. Class 75(1). An oil fuel burner 17, provided with a valve 24 which seals oil within the burner when the latter is removed from its holder 11, is detachably held to the holder 11 by a securing screw 14 fitted with a handwheel 14a covered by a hand lever 8 which is held down by a trigger 9 and is adapted to depress a valve spindle 4 and open a spring-loaded valve 2 to allow oil 15 to be fed to the burner. Thus before the handwheel 14a can be operated to release the burner 17 the trigger 9 must be disengaged and the lever 8 raised to allow the fuel valve 2 to close. The resulting fall of pressure in the fuel passage 28 in the holder 11 causes the spring pressed ball valve 24 to close, so that the oil does not spill from the burner 17 as it is removed. The lever 8 and handwheel 14a are of such dimensions that when the handwheel is turned so as to free the burner its position is such as to prevent engagement between the lever 8 and the valve stem 4 so that the valve 2 cannot be opened. The burner holder 11 is provided with slots for receiving studs whereby it may be adjustably mounted on a support 26 (not shown) and moved up or down to disengage or engage the oil inlet 10 with or from the burner.

Title: Improvements in or relating to devices for the sealing of a rotatable shaft in passage through a casing
Inventor: WHITLEY STANLEY
IPC: F16J15/44
Filed: 1959-01-28
Abstract: 881,877. Stuffing-box substitutes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 6, 1960 [Jan. 28, 1959], No. 3046/59. Class 122 (5). Means for sealing a rotatable shaft 1 where it passes through a casing 4 comprises a body 5 resiliently sealed in the casing and provided with a bore for the shaft, the bore defining with the shaft, in order from the outer end of the casing, an externally-pressurized orifice zone at 22, 23 for sustaining gas lubrication and support between the body and the shaft and a pressure-adjusting zone provided by a circumferential groove 24 with a hole 29 for venting gas from the groove. As described for the pumping of reactive or toxic gases in the casing 4 by an impeller mounted in the casing on the shaft 1 which is driven from outside the casing, the body 5 is in the form of a sleeve supported by a flexible diaphragm 7 which is sealed to respective flanges 6, 10 on the sleeve and inner end of a hub 11 arranged to be supported at its outer end by a similar diaphragm 15 sealed to the end plate 3 of the casing. In operation, compressed gas, such as air, is supplied through pipes 27 to two sets of circumferential orifices 22, 23 in the sleeve to provide gas lubrication and support between the sleeve and shaft and is vented to atmosphere both at the outer end of the sleeve and through the groove 24 and a set of radial holes 29 in the sleeve. Sealing gas, such as nitrogen, is also fed through a pipe 30 to a further groove 25 in the sleeve and inverted to atmosphere in one direction through the holes 29 and in the other through a still further groove 26 and outlet pipe 32; some of this gas also passes into the casing 4. In a modification, sealing gas under pressure is fed to the orifices 22, 23 and the groove 25 and associated pipe are dispensed with; in this ease, of the gas passing inwardly along the shaft some is vented to atmosphere through the holes 29 and pipe 32 and the rest flows into the casing. It is also possible to dispense with the groove 26 and pipe 32. In an application of this device in which the casing 4 forms part of a gas-cooled nuclear reactor using carbon dioxide at 25 atmospheres as coolant, the groove 26 is fed with carbon dioxide at 26 atmospheres and the groove 25 with air at 25 atmospheres, or reactor carbon dioxide from the casing and air supplied at 25 atmospheres to the groove 25 are drawn off through the groove 26 at 24 atmospheres. In these arrangements, a flexible gimbal mounting is provided between the sleeve 5 and end-plate 3 to prevent axial movement caused by the high axial pressure load. If desired, the grooves 24, 25, 26 may be provided in the surface of the shaft instead of in the sleeve, the holes 29, 34, 35 being arranged in the sleeve, and the sleeve may be supported by bellows instead of by diaphragms.

Cameras, roll-film; roll spools.-Roll films are wound on flangeless spools 22, 16 of triangular or polygonal section which may be formed solid or by bending a strip of metal or other material to form a triangular or polygonal tube with an elongated opening in which the end of the film is held. Automatic means are provided for winding the required quantity of film after each exposure. The film 14. Fig. 2, is mounted on a triangular spool 22 and led over rollers 12, 13 and has mounted thereon a second triangular spool 16 formed by bending a strip of material into triangular shape and inserting the film in the elongated slot therein. The spools are held in place by triangular centres 31, 62, Fig. 1, moved in and out of engagement therewith by cam sleeves described below. The film is kept tensioned by means of spring-pressed plates 24, 42. The triangular take-up spool 16 is received in and correctly centred by a V-shaped groove 34, Fig. 6, carried by a metal strip 35, bearing eyes through which passes the rod 38, and held in position by the springs 46. Threaded on the same rod are spring-pressed plates 42 by which the tension on the film is maintained. The centres are moved in and out of engagement with the spools by means of a finger piece 49, Figs. 2 and 15, attached to a curved arm 50 carrying a rod 52 guided in curved slots in the camera case and passing through holes in the rock-arms 55 through which passes the threaded part 59, Fig. 3, of the centring-pin. Sleeeves 63, attached to the casing by means of a screwed closure 65, have cam grooves 68 therein engaging keys 69 on the arms 55 so that, when the member 49 is depressed, the arms 55 and with them the centres. 52 are moved into engagement with the spool. In order to avoid winding the film by hand. spring-driven gear is provided. The spring drum 72, Figs. 1 and 9, drives the spool through a train of gearing, one spindle of which carries a ratchet wheel 75 engaged by a pawl 80 the outer end of which is operated by a sleeve 81 on the spring- pressed rod 82, sliding in bearings 83 and engaging at its outer end the hemispherical end 87 of a plunger 89. On depressing this plunger, the pawl is raised and the train of gearing operated until the next tooth of the ratchet wheel is engaged by the pawl when sufficient film for one exposure will be wound. A disk attached to the spindle of the ratchet wheel carries figures which show through a window in the casing and indicate the amount of film wound. Finger pieces 61 attached to the centres permit the film to be wound by hand. The film is provided at its inner end with a gummed tab by which the spool is sealed after exposure.

Abstract: 747,443. Letting off warps in looms. SULZER FRERES SOC. ANON. Feb. 3, 1954 [Feb. 21, 1953], No. 3258/54. Class 142 (2). A warp beam is given increments of rotation at regular intervals, the magnitude of the increments being goverened by the tension of the warp. A shaft 33 drives the beam 10 through an intermittently-engaged clutch 31, 32 and gearing 34-37. The driving element 31 of the clutch is splined on the shaft 33 and has a cam track 44 running against a fixed roller 45, whereby the clutch element moves towards and away from the driven element 32 once in every revolution of the shaft 33. The element 32 is splined on the driven shaft 47, and is slidable in a housing 51, in which it is spring-loaded towards the right, its movement in that direction being limited by a brake disc 49 coming against the end of the housing; the housing is positioned in accordance with the tension of the warp by connections from a movable back-rest 12 loaded by a spring 19. If the tension of the warp increases, the housing 51 moves to the right, causing the driving element 31 to encounter the element 32 earilier in the cycle; the spring loading of the element 32 enables the element 31 to continue its movement to the left, thereby removing the brake 49 and rotating the beam 10 until, as the element 31 returns to the right, the brake re-engages and the clutch elements separate. The movements of the back-rest 12 are transmitted by a lever 38 and a link 39 to a lever 41 formed with a cam slot 62 engaged by a roller 64 on a bellcrank lever 54, so that the end thrust on the clutch element 32 cannot react on the back-rest 12. In a modification, the housing 51 has cam slots engaged by followers fixed to the loom framework, movement of the back-rest 12 causing the housing to turn and therefore move endwise. In another form, a feeler shoe presses on the warp between a back-rest and the harness 22, the lever carrying the shoe being formed with a face cam which causes endwise movement of the housing 51.
