Filed: 1930-05-07
Abstract: 353,118. Fluid-actuated valves. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London, and SMITH, W. A., Broadway Buildings, Broadway, Westminster. May 7, 1930, No. 13988. [Class 135.] Valves controlled by pilot or relay valves.-An automatic pulsating valve device particularly adapted for use in connection with pneumatic soot blowing systems comprises a main piston valve f and a control valve i which operates to admit pressure to or release pressure from the upper side of the main piston valve. The main valve is loaded by a springh and controls an outlet port e. The auxiliary valve which is adjustably loaded by a spring l comprises a piston with two circumferential grooves j, k connected by internal passages m, n to opposite ends of the piston. Inlet pressure is admitted through passages d, m, j, g and when the pressure has reached a predetermined value the valve lifts against the action of the spring to connect the space above the main piston to atmosphere through passages g, k, n, p. As the main piston rises to open the outlet port it closes the port g. The main piston may be arranged so that its initial movement opens an exhaust port q formed in the piston-rod. The piston-rod may be coupled to a pawl-and-ratchet mechanism for rotating the soot blower heads.

Title: Improvements in automatic switches for use in telephone or like systems
IPC: H01H63/04
Filed: 1935-05-15
Abstract: 456,767. Automatic exchange switches. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and SAXBY, R. N., 36, Millersdale Road, Mossley Hill, both in Liverpool. May 15, 1935, No. 14260. [Class 40 (iv)] In automatic switches, particularly bidirectional, with a pair of wiper tips engaging opposite sides of a contact track, misalignment of the wipers with the contact track causes reduction of pressure of one or other of the tips with its contacts. To cure this defect, the wiper tips are mechanically interconnected adjacent their ends to prevent them from separating more than a predetermined distance. As shown in Fig. 1, wiper tips 10, 11 are prevented from separation by an insulating ring 12 whereas in Fig. 2, separation is prevented by hooks 13, 14 and an insulating piece 15. Movement of the wiper tips is limited by a fixed insulating member 9. Each wiper tip may be of twin form as shown in Figs. 4 and 5 and the separation preventing arrangements of Figs. 1 and 2, are applied only to the inner tip of each twin, The contact made by a twin tip is along a radial line, a twin tip being formed from a single pressing by bending back one tip portion. The clip shown in Fig. 9 is adapted to be sprung on to the wiper shaft and has a loop 26 with turned over edges to accommodate the wiper leads. One end of the clip is notched to engage a part of the wiper mounting for locating it. The Provisional Specification also describes the arrangement shown in Fig. 3 in which the wiper blades may be more rigid than in the above construction and are pivoted as a unit at 16 to the wiper shaft.

[Class 94 (ii).] In making paper bags from tubular blanks by closing one end of the blank and thereafter closing the other, the bag is turned round end for end between the closing operations whilst retaining at all times mechanical engagement with the reversing means which operate positively and automatically. Tubular blanks B<1>, picked one by one from a pile by oscillating fingers b, b<1>, are fed by a rotating segment b2 and arm B<3> through feed rollers C<1>, c to co-operating rollers C<2>, C<7>, one of which carries a pin c<1> adapted to pick up the flap of the thumb tag of the blank while a cam-operated lever c<2> on the other roller C<2> grips the lower flap to draw the blank round the roller, a finger C<6> engaging the upper flap to open out the blank. Feed rollers C<9> .. C<11> pass the blank to tapes L which co-operate with the edges of discs D constituting a creasing cylinder and carrying fixed and adjustable pads D2, D<3> against which creasing blades K<2>, K<1> operate. A pad e on a roller E<1> applies gum as shown in Fig. 2a. Tapes L<1> now act in conjunction with the tapes L to convey the creased blank around a folding cylinder F. The folding cylinder comprises two sets of cam-operated folding arms F3, F<4>, the arm F<3> folding down the front flap b<3>, Fig. 2a, and pressing it until the arm F4 folds down the rear flap b4 on to it. Rollers l<1> . . l<4> feed the bag on to a reversing cylinder G. This cylinder comprises two spaced discs G<1> connected by bars g<10>, Fig. 3, and the folded bottom of the bag is fed against a bar g<10> and held there by a bell-crank lever G<3> actuated by a fixed cam g<1> which releases the lever when the rear end of the bag is brought between pairs of co-operating rollers G<6>, G<9> disposed outside the discs G', the roller G<9> having a recessed portion g<5> which permits passage of the bag. As the lever G<3> releases the bag, the wider part g<4> of the roller G<9> engages it and reverses its direction of motion, projecting its unfolded end into a cam-operated hook g<6> associated with a roller G<10>. The unfolded end of the bag is now folded by mechanism similar to that used on the first end except that the gumming pad applies gum as shown in Fig. 3c and not as in Fig. 2a to leave a filling valve in the completed bag.

Title: Processes and apparatus for the catalytic cracking of hydrocarbon oiis
IPC: B01J8/26
Filed: 1955-05-18
Abstract: <PICT:0769818/III/1> In a process for the cracking of a hydrocarbon oil wherein fluidized catalyst is cycled through the reactor 1 and a regenerator 2, and the catalyst withdrawn from the reactor is stripped with a gas such as steam to remove volatile hydrocarbons, the stripper 3 is situated within the regenerator, the stripped catalyst flows through openings 14 directly into the regenerator, and the vapours from the stripper are passed via a valved-line 10 into the vapour space of the reactor.  The invention renders unnecesary the use of a standpipe with a control valve between the stripper and the regenerator.  The hydrocarbon oil to be cracked is passed into the reactor through line 4, together with regenerated catalyst which is drawn off from the regenerator via standpipe 5 and slide-valve 6. Spent catalyst flows from the fluidized catalyst bed in the reactor via a stand-pipe 7 into riser 8, through which it is transported in a dispersed phase into the stripper by means of steam injected through line 9.  The riser 8 extends above the level b of the catalyst bed in the stripper; and the catalyst particles issuing from the top of the riser fall into this bed, which is kept in a fludized state by means of steam supplied at the bottom via lines not shown.  By means of valve 11 in line 10, the pressure in the gaseous phase of the stripping space, and thus the catalyst-level in the stripper, can be kept constant in case the pressure in the reactor becomes higher or lower.  Specification 718,578 is referred to.

Filed: 1969-03-19
Abstract: 1,244,805. Valves. BRYAN DONKIN CO. Ltd. 3 April, 1970 [19 March, 1969], No. 14483/69. Heading F2V. [Also in Division G3] A gas supply shut-off valve has a valve member 24 which is mounted on an arm 22 hinged about a pivot 18 and is normally held in an open position by a roller 46 engaging a pivoted detent 40. The roller is mounted between a pair of plates 48 that in turn are mounted on a link 52 extending between the arm 22 and a link 56 pivoted at 58 and biased by a spring 60. Excess rise in fluid pressure downstream of the valve is communicated to a chamber 70 below an adjustably spring-biased diaphragm 68 so that the latter moves upwards and raises the detent 40 via rod 76. The valve member falls under gravity and the influence of the spring 60 to shut a seat 32 and the links 52, 56 assume an overcentre position with a stop 62 on the plates 48 abutting link 56. A resilient seal 30 on the valve member ensures a fluid-tight seal in closed position. The valve is moved to the open position by rotation of shaft 58. The valve may also be closed on rise in outlet pressure by connecting a relief valve (116) between the outlet and chamber 70. The rod 76 may be sealed by a seal 86 or a seal (100) mounted on the rod and normally abutting the top of the bore through which the rod extends. The rod 86 may be pressure balanced. In a modification the pivoted detent is replaced by a block mounted on a leaf spring and a spring-loaded seal surrounding a cable (104) between the diaphragm and block seals about the lower end of the bore through which the cable passes.
