Title: An improved wick and burner therefor
IPC: F23D3/00
Filed: 1938-01-04
Abstract: 506,192. Wick burners. IMBER, J., and ALADDIN INDUSTRIES, Ltd. Jan. 4, 1938, Nos. 261,10881, and 20929. [Class 75 (i)] Annular wicks for blue-flame lamps, stoves and heaters are stiffened by metal plates 3 extending down the tail portions 2 from slightly above the lower end of the cylindrical portion 1. The metal plates 3 are secured to the wicks at the top and sides by prongs 4 and are provided at the base with sockets or eyelets 5 engaged by the wick-operating mechanism below the level of the burner basket 11. In the construction shown, the wick-operating spindle 16 extends through two opposite side-draught passages 9 and carries a pinion 19 engaging a rack 20 slidable in a guide 21 on a horizontal partition 13 extending across the inner wick tube, and a horizontal bar 22 secured to the rack carries a rod 23 passing through the eyelets 5. The sockets or eyelets 5 may be formed in or fixed to the plates 3 or formed in or fixed to the wick and secured, for example, by press stud elements to the plates 3. The inner wick tube may be extended downwardly and formed with guide-slots through which the rod 23 passes. Alternatively, the rod 23 may be bent upwardly and secured to the upper end of the rack 20, the bar 22 being dispensed with. According to one Provisional Specification, the stiffening of the wick may be effected by chemical impregnation or by the application of textile or adhesive stiffening elements.

Abstract: 808,240. Hull construction. ALBIACH, V. Jan. 3, 1957 [Jan. 7, 1956], No. 362/57. Class 113. In a ship's hull, suitable for shipping bulk cargo of widely-different kinds, comprising a double bottom forming ballast tanks, the tops 4 of ballast tanks on which the cargo rests are supported and stiffened by transverse beams 5 fastened to the structure of the sides 9 of the hull so as to transmit part of the weight of the cargo to the sides of the hull. Longitudinal bulkheads 10 form, together with the tank tops, a double hull, the transverse beams 5 being connected to the structure of the bulkheads so as to transmit part of the weight of the cargo thereto. Connections 7, Fig. 2, between the transverse beams 5 and the ship's bottom 1 may be replaced by pre-tensioned tie rods 38, Fig. 3. Bilge compartments 11 have sloping tops 12 defining the bottom of side cargo compartments or tanks 8 formed by the ships side, the longitudinal bulkhead, and sloping tops 16 attached-to carlings 32 at the hatch opening 33. The bottom end 39 of the bulkhead is bent towards the upright reinforcement 40 so that forces applied to the base of the bulkhead will not cause bending of its main portion. Horizontal stringers 13, 15 attached to the shell 9 and bulkheads 10 have downwardly sloping webs to facilitate loading of cargo into the compartment 8. Transmission of loads at the junction of the floor 4 with other structural members, e.g. with the sloping members 12 and the side keelsons 7 is accomplished by welding to a flanged or beaded plate 44, Fig. 8. In Fig. 6 a transverse bulkhead 34 separating hold compartments has an opening 35 closable by a panel 36 pivoted at 37 to be swingable to a horizontal portion in which it provides a 'tween-deck for freight. In Fig. 7 the opening of the transverse bulkhead 34 is closed by a panel 42 rockable about a pivot 41 to provide a hopper side wall. The bottom part of the bulkhead is shown removed to facilitate handling the cargo in the hold.

Abstract: 618,867. Fluid-actuated valves. SOC. MESSIER. Jan. 4, 1946, No. 389. Convention date, Dec. 24, 1943. [Class 135] An automatic hydraulically-operated valve, e.g. for controlling a byepass to a pump, comprises a piston valve controlling connection between two ports, means by which hydraulic pressure urges the valve to its open position against a spring, a movable seating for the spring and operative connections between the seating and a restraining means for yieldingly holding the valve in either its open or closed position. As shown, the valve comprises a housing having a conduit 2 connected to a hydraulic circuit, a conduit 4 leading to the circuit and a pump, and a conduit 6 leading to a sump, communication between the conduits 4 and 6 being controlled by a piston valve 9 actuated by hydraulic pressure in the conduit 2 acting on a piston 14. The valve has two pairs of notches 22, 23, engageable by rollers 24, 25, carried by bell-cranks 26, 27, pivoted on a tubular member 19, the rollers being forced together by a pin 34 pressing on the arms 32, 33 of the bell-cranks and carried by a link 35 connected to the spring-loaded sleeve 38.

Filed: 1925-01-06
Abstract: 228,136. Silica Gel Corporation, (Assignees of Miller, E. B., and Benzon, A.). Jan. 23, 1924, [Convention date]. Refrigerating, vacuum processes for.-In processes of the kind described in Specification 225,191, wherein the vapour from a brine or water evaporator is adsorbed by a solid material having fine pores, such as silica gel or cocoa-nut charcoal activated in the presence of steam, the vapour is recovered from the adsorbent, condensed and returned to the evaporator, and the use of exhaust pumps during operation is dispensed with. The apparatus comprises a closed evaporator 110, an adsorber vessel 113, a condenser 125, cooled by a coil 136, and a water heater 131 for use in reactivating the adsorbent. The evaporator communicates with the adsorber through a pipe 112 fitted with a valve 142, and with the condenser through a pipe 127 fitted with a valve 143. The vapour driven off from the adsorbent returns to the condenser through a pipe 126. The apparatus is particularly adapted for domestic use and the closed system comprising the condenser, evaporator and adsorber is exhausted before use, either by the use of a pump connected with a third branch of the valve 142, or by heating the evaporator to displace all the air by vapour, the opening being sealed before the apparatus is used. Cold water from a main is supplied through a pipe 132 fitted with a valve 133 to the pipe system comprising a coil 140 in the heater 131, a coil 128 in the adsorber. and a connecting pipe 130 fitted with a valve 134. During the refrigerating period the valve 143 is closed and the valve 142 is open to permit the adsorption of vapour from the liquid in the evaporator. The water in the pipe system 140. 128 is unheated and after circulating as a cooling medium through the coil 128 flows to waste through a valve 135. At the end of the refrigerating period the valve 142 is closed and the valve 143 is opened, the water valves 133 and 135 are closed, and the water contained in the pipe system 140, 128 is heated, as by a gas burner 141, to reactivate the adsorbent. When all the vapour is re-condensed the process is reversed. The valves may be controlled automatically by a. thermostat.

Abstract: 1,131,232. Mowing machines. NATIONAL RESEARCH DEVELOPMENT CORP. 30 Dec., 1965 [6 Jan., 1965], No. 628/65. Heading A1F. [Also in Divisions B4 and F1] In a transducer for driving the blades of a grass cutting machine wherein a driving piston 51 is oscillated in a cylinder 52 by pressure pulsations supplied from a source S to a chamber 53 on one side of the piston and by spring action of hydraulic fluid filling a space 56 connected to a chamber 55 on the other side of the piston, excessive movement of the piston 51 to the left operates a spool valve 67 to direct, through ports 69, 71, fluid from an accumulator 74 to a duct 54a, 54 connected to the chamber 53 to thereby reduce the excessive movement. The accumulator is charged to a higher mean pressure than the space 56 since the charged fluid has to pass through a non-return valve 75. The space 56 is large compared with the chamber 55 and may have an annular wall, Figs. 2 and 4 (not shown), movable in response to pressure acting thereon against the adjustable spring action of a stack of Belleville washers or a helical coil. To maintain the transducer full of fluid at a desired pressure, fluid is supplied to the space 56 by a backing pump 59 delivering through a pressure reducing valve 61, a stop valve 62 and a non-return valve 63. If fluid leaks from the right hand chamber 55 the spool valve 67 exhausts fluid from the chamber 53 and the valve 63 opens to admit fluid to the space 56. In a second embodiment, Fig. 6 (not shown) the transducer has a differential area piston provided with internal passages which co-act with cylinder ports to perform the function of the spool valve of the above embodiment.
