Filed: 1929-04-11
Abstract: 309,500. Wright, G. N. April 11, 1928, [Convention date]. Washing-machines.-The articles to be washed are placed in thin loose layers in alternate compartments formed in a flexible net receptacle by horizontal diaphragms formed of netting. The receptacle is carried by a piston plate 14 which is reciprocated vertically within the liquid-containing tank 5, and at the bottom of its stroke the receptacle collapses and squeezes the contents with a pressure which may be adjusted by varying the lower limit of the stroke of the piston plate. The piston plate 14 is yieldingly connected to an inverted U-tube 17 which is guided in a stationery tube 36 enclosed in a casing 38. A vertical rack is formed along the outside of the U-tube and is engaged by a pinion 45 driven in alternately reversed directions from a motor 51 through automatically reversed bevel gear contained in a casing 50 and chain and sprocket gear 48, 52, 47. The reversal of the drive is controlled by the sliding movement of a rod 62 in alternately opposite directions, the rod being linked to a bell-crank lever pivoted at 66, the free end 68 of the bell-crank lever being engaged alternately by the bottom and top of a vertical slot formed in a tube 40 within the U-tube 17. The top of the slot in the tube 40 is formed as a series of stepped shoulders and the tube is rotatably mounted within the U-tube so that any one of these shoulders may contact with the free end 68 of the bell-crank lever on the downward stroke of the U-tube and piston and so vary the lower limit of the stroke thereof. Movement of the tube 40 is controlled by a handle 41. The bevel gear drives the shaft on which the sprocket wheel 48 is mounted through a clutch controlled by a lever 84, the drive being either direct for washing or indirect, through a 4: 1 reduction gear, for reciprocating the receptacle more slowly for drying purposes. Means to disconnect the drive producing the downward movement and to connect up the reverse drive if the receptacle jams during its downward movement comprise a spring pressed plate freely mounted on the shifter rod 62 but held out of engagement with a flange thereon by means of an armature spring- pressed away from a solenoid in series with the motor 51. When the receptacle jams the current rises and draws the armature against its spring so as to free the plate on the rod 62 thereby enabling the plate to engage the flange on the rod and move the latter to the reverse drive position.

Title: Improvements in or relating to emergency stop valves for compressed air brakes
IPC: B60T17/20
Filed: 1918-07-09
Abstract: 152,372. Knorr-Bremse Akt.-Ges. Sept. 8, 1917, [Convention date]. Fluid-pressure.-Valve apparatus for applying train-brakes when a danger signal is overrun, of the kind comprising a valve which is locked in the open position when actuated, as by a track contact, is provided with means for preventing the locking-device from acting and for closing the passage which is opened by the valve, whereby the application of the brakes may be prevented. The valve c works in a chamber of which the upper part is connected directly to the train-pipe b of the brake system, and normally the pressure equalizes into the lower part of the chamber through a port 2 so that the valve is held by the spring d in the raised position to close the exhaust port 1. A second valve 3 normally closes the lower chamber of the valve c. Engagement of the member g with a track contact raises the lever f and the valve 3 to the open position in which it is adapted to be held by a catch h. The lower chamber of the valve c is thus vented through the passage 4 and the valve thereby moved down to vent the train-pipe through the port 1. To render the apparatus ineffective, an electro-magnet l may be provided adapted when energized by the driver to close the passage 4 by a valve i and to hold the catch h in the disengaged position. A fluid-pressure cylinder k and piston may be substituted for the magnet l.

Title: Improvements in tubulous vapour generating and superheating units and a method of controlling the temperature of superheat in such units
IPC: F22B21/34
Filed: 1955-04-21
Abstract: 781,909. Combustion apparatus. BABCOCK & WILCOX, Ltd. April 21, 1955 [April 23, 1954], No. 11596/55. Class 51 (1). [Also in [Group XIII] A water-tube boiler has a furnace 10 lined with steam-generating tubes and fired from the front wall 12 by a single horizontal row of four whirling flame pulverized coal, oil or gas burners, hot gases leaving the upper part of the furnace laterally to flow over a superheater 36 and sinuously through the boiler convection section between baffles 104 ... 106 to a breaching 130 conveying the gases to an air heater 132. Steam flows from the drum 20 through the superheater 36 to an outlet header 126. Alternatively the steam may flow from the header 126 through two parallel-connected radiant superheated sections respectively disposed on the furnace side walls. Cool flue gas is extracted from breaching 130 by a fan 37 which directs it into the throat 32 of the furnace hopper bottom, the quantity of gas recirculated being controlled by a damper 44 actuated by a power device 52 in response to variations in superheat temperature. To prevent unbalance in furnace side wall heating, the burners adjacent the side walls are arranged to provide flames which whirl in opposite directions. As shown in Fig. 3, the burners are divided into two groups A and B, the burners 60, 62 of group A having their secondary air vanes 68, 70 set to provide clockwise rotation of the air stream about the air-borne coal stream from the burner nozzles whilst the burners 64, 66 of group B have their air vanes 76, 82 set to cause an anticlockwise rotation. By having the burners 60, 66 arranged to deliver flames of opposite rotations. a more uniform and equalized. flow of recirculated gas along the side walls 16, 18 is obtained. Moreover, the concentration of recirculated gas on the side walls screens the generating or superheating tubes thereof from radiant heat and renders the flow regulation of recirculated gas more effective in controlling steam temperature. Specification 781,910, [Group XIII], is referred to.

Abstract: 651,904. Casting-machines. PLASCO, Ltd. April 29, 1948, No. 11750. Convention date, June 7, 1947. [Class 83 (i)] Moulds ; extracting castings.-A die-casting machine comprises a pair of dies 33, Fig. 1, movable towards each other and held closed by a pair of hydraulic cylinders 44, an automatically-actuated valve 53, Fig. 2, controlling the supply of oil to and from the cylinders, and a transfer and stripper mechanism, itself comprising a core pin 104 pivotally supported beneath the dies, automatically actuated means for moving the pin, when the dies are opened, with a casting supported thereon to a trimming station and then to a stripper station, and automatically-actuated means 119 movable longitudinally of the pin to strip that part of the casting remaining on the pin from the pin at the stripper station. Supports 25, Fig. 3, carry detachable brackets 34 to which the dies 33, are secured. Plates 30, Fig. 1, may be swung upwards to allow removal of the dies and brackets from the supports. Each support 25, Figs. 3 and 4, is moved in adjustable guideways 21, 22 by a hydraulic piston 47 returned by springs 46. The piston and spring assembly is detachable from the support 25 and from the frame-plates 14, 17 by pins 61. The casting is formed on the carrier pin 104 mounted on the cylinder of an air-actuated piston 118, the cylinder being oscillatable with a shaft 109. An electric motor 13, Figs. 1 and 2, drives a main shaft 12 carrying cams 79 and 137 and rotating an adjustable cam 54. The cam 54 controls the supply of hydraulic fluid to the pistons 47 ; the cam 79 controls the movements of an adjustably-supported gooseneck 80 through a lever 77, and the cam 137 controls the oscillations of the shaft 109 to move the pin 104 carrying the casting first to a trimming station and then to a station where the piston 118 is actuated to strip the pin. The cam 137 acts through an arm 129, spring 131 and gear sector 124 so that, in case of obstruction the movement of the arm 129 is absorbed by the spring 131. In the opposite direction of movement a spring 141 provides a safety device. In the closed position of the dies 33, controlled by screws 87, Fig. 3, pistons 67 are moved by screws 66, carried by the supports 25, to close an air-line 70. Should the dies fail to close fully, compressed air entering the line 70 actuates a switch 72, Fig. 1, to stop the motor 13 and to close a valve 81 which supplies pressure air to the molten metal pot 96. Pressure is then also supplied to a piston 73 which raises the lever 77 to withdraw the gooseneck 80 from the dies. A handlever 142 withdraws the pot from the dies. Specifications 542,647 and 546,155 are referred to.
