Title: Improvements in apparatus for assembling girders, spars and like members of aircraftand similar light structures
IPC: B21D39/02
Filed: 1927-06-30
Abstract: 297,874. Boulton & Paul, Ltd., and North, J. D. June 30, 1927. Drilling-machines. - Light girders for aircraft &c. e.g. of assembled section as shown in Fig. 3<A> are passed step by step through a machine which clamps by rollers the two side flanges of the bottom section between the bends of the intermediate section while two or more drills are moved into position by treadle to bore the bottom flanges and, further on, rivets are hand inserted and riveted by treadle-operated riveters. When the two bottom flanges are riveted the girder is re-inserted upside down to finish the top flanges. The girder is fed forward step by step and seamed by bottom rollers B<4> the middle part of which is knurled to help the feed, and guided by loose top rollers B<5> on the same vertical spindles and by top and bottom adjustable grip-rollers D<4> on horizontal spindles. The two top bearings A<3> of each vertical spindle can be adjusted while the bottom bearing is adjusted in position by dowel pegs. For different flange widths of girder the whole side bracket A<2> is moved laterally, thereby moving the vertical spindles on that side and at the same time the drill and rivetter also on that side. Adjustable idle rollers receive the end of the girder which has passed through. The four spindles of feed rollers B' are driven by gearing B<8> from a ratchet clutch operated by treadle to advance the girder step by step. When the drill control lever L<3>, Fig. 2, is turned by hand it lowers a cam M out of contact with a pin M<5> on lever L so that this lever is free to fall against dash-pot action by a weight on its end and in so falling it pushes up sliding block H<1> in which the drills H are mounted so that the drills contact with the flange. The drill control lever also simultaneously moves a cam M<1> to push a locking lever M<3> into the path of the feed mechanism lever G<4> to arrest the feed. The drills are driven from an electric motor by belt, arranged over pulleys to keep the belt tight in all positions of the drills. The drills are withdrawn by hand-raising lever L. Each drill is mounted in its quill by ball bearings and the quill is mounted in a vertically adjustable sliding block H<1>. The drills are driven by belt from an independent electric motor.

Title: Improvements in or relating to contacting gases with powdered solids
IPC: B01J8/38
Filed: 1951-07-23
Abstract: <PICT:0701231/III/1> In a process for contacting gases and solids wherein finely divided solids are continously circulated between separate contacting zones in each of which the solids are maintained as a dense fluidized bed having a dilute phase thereabove, the amount of fines, e.g. below 40 microns lost from the system is compensated by jetting a gas into a dense phase region of the system to break up larger particles to fines thereby maintaining a more smooth operation.  The process is particularly applicable to hydrocarbon conversion wherein there is a conversion zone and regeneration zone and catalyst such as silica-alumina or silica-magnesia of 1 to 100 microns size is employed.  In Fig. 1, oil to be cracked is introduced through line 1, preferably through a plurality of spaced points, into a transfer line 2 where it meets hot regenerated catalyst and steam from regenerator 12.  The mixture of oil vapours, steam and catalyst pass to a reactor 5 and cracked vapours are withdrawn at 7 the catalyst is withdrawn through pipe 11 to regenerator 12 after stripping and is regenerated by steam, and air from pipe 13.  The catalyst is discharged into a stand-pipe 3 and thence through valve 17 to a conduit 18 where jets of inert gas such as steam are introduced from pipes 19 of velocities from 500 to 3000 f.p.s. to grind the particles by mutual attrition.  The jets may be located at other dense phase regions such as the dense phase beds in the contacting vessels.

Title: Improvements in or relating to slip couplings
Inventor: POWER BASIL DIXON
IPC: F16D31/06
Filed: 1959-05-14
Abstract: 921,821. Hydraulic couplings. EDWARDS HIGH VACUUM Ltd. May 14, 1959, No. 17428/58. Class 69 (2). An hydraulic coupling comprises driving and driven members 1, 4, Figs. 1 and 2, arranged so that when the speed of the driving member exceeds the speed of the driven member a positive pumping action by the driving member causes liquid to be pumped around a closed path, a relief valve 16 in the path, normally blocking the flow of liquid, opening when the pressure difference across it reaches a predetermined limit, and means for inducing air into the liquid at a point where it can mix with the liquid to form an elastic and compressible medium. The driving member 1 has sliding vanes 8 which may be hydraulically or spring- urged into contact with an eccentric bore in the driven member 4 and draw liquid through an inlet 14 and pump it through an outlet 15, the inlet and outlet being connected to a reservoir 13 formed in a cover secured to the member 4 which may be connected by gears, bolts or a chain to a machine to be driven. The relief valve 16, which may be of the preset adjustablyloaded pressure-release type, normally closes the outlet but opens when the torque transmitted exceeds a predetermined value to permit slip to occur in the coupling. Out-of-balance forces in the coupling may be prevented by the provision of a pair of inlet ports and a pair of outlet ports, the ports of each pair being diametrically arranged. Noise when the coupling is slipping caused by the vanes passing the ports reduced by a pipe 43, Fig. 6, having holes 46 connecting an air space 45 formed within the reservoir by the centrifugal action of the fluid with the inlet ports 24, the air mixing with the liquid to form a compressible mixture. In other embodiments, the driving member may be in the form of a gear pump or have a camshape 34, Fig. 5, which co-operates with spring- urged blades 35 mounted in the driven member 36. The coupling may be cooled by fins formed on the reservoir cover or a fan on the driving shaft. Specification 680,001 is referred to.

Abstract: 700,575. Projectile fuzes. MEFINA SOC. ANON. July 31, 1951 [April 13, 1951], No. 18067/51. Class 9(1) Relates to clockwork fuzes of the kind in which the clockwork mechanism controls the movement of a member which is pivoted eccentrically relatively to the axis of the fuze and which is moved, on firing, by centrifugal force, the said member controlling the movement towards its active position of at least a portion of the primer. According to the invention the centre of gravity of the member 36 is located, when the fuze is at safety, in a semicircle whose diameter is the line joining the spin axis of the projectile and the pivotal axis of the member, the semicircle being on the side of this diameter towards which the member moves from its position of rest. The arrangement is such that the angular acceleration of the projectile opposes the movement of the member towards its armed position. In the construction shown, a pivoted catch 37 swings outwards under centrifugal force to release the member 36. The speed of the released member about its axis 36a is controlled by escapement and balance wheels 31, 30, associated with gears 34, 35. After a given time a cut-out part 43 of member 36 registers with a notch 42 of a disc 41, to which is secured an unbalanced lever 39 carrying the primer 7, and as the disc is weighted at 47 it rotates, when released, to bring the primer 7 into line with the main charge. Stops 44, 45, limit the rotational movements of the member 36 and disc 41. In a modification, Figs. 5 to 7 (not shown), the primer is mounted on the movable member. Specification 551,654 is referred to.
