Title: Improvements in steering gear for automobile vehicles
IPC: B62D7/00
Filed: 1929-05-07
Abstract: 311,335. Rheinische Metallwaarenund Maschinenfabrik S÷mmerda AKt.-Ges., and Faudi, F. May 9, 1928, [Convention date]. Steering-gear.-The effective length of the drag link or other member connecting the stub axles to the steering-gear is automatically varied in accordance with changes in the relative positions of the stub axles and the chassis frame due to flexure of the springs, so that the direction of the steering wheels is not affected by the spring movements. In the construction shown in Figs. 1 and 2 the stub-axle is pivoted at b to a dead axle c and the stub-axle arm g is connected to the operating arm f by a drag link h. The front end of the link slides in a member h1 pivoted at h2 to the arm g, this sliding movement being controlled by a roller h7 on the link cooperating with guides h6 in the member. These guides are so shaped that, when the wheel strikes an obstacle and the spring d3 is flattened so that the axle c pivots about the front end d1 of the spring, the end of the link slides towards the rear in the member h1 and compensates for the movement of the axle. In the construction shown in Fig. 4, applied to a vehicle having wheels independently spring mounted on arms i pivoted on an axis i1 on the frame d, a steering arm f is connected to the stub-axle arms g by separate links h each having a sliding and cam controlled connection with a member h1 similar to that described in connection with Figs. 1 and 2.

Title: Improvements in or relating to remote operating tools
IPC: B25J1/02
Filed: 1958-05-08
Abstract: 931,441. Handling radio-active material. L. JENKS, and H. S. G. VINER. Aug. 10, 1959 [May 8, 1958], No. 14806/58. Class 39 (4). [Also in Group XXIII] A long arm reacher comprises an arm 1 having at one end a detachably mounted head 5 with jaws 24, 25 and at or towards the other end an actuating member connected to the head by operating means including a rod 7 and a releasable coupling comprising a pair of members 41, 16 which are movable into and out of engagement in the direction of the axis of the arm and include interengaging projection 46 and recess 47 which are biased into operative engagement with each other by means of a spring 68. In the embodiment of Fig. 1, the head comprises a curved arm portion 22 with a socket 23 into which the arm portion 2 is fitted, stud 38 engaging longitudinal slot 39 in the portion 2 to prevent relative rotation. The actuating member comprises a handle 3 fixed to the arm and a handle 4 pivoted to the arm at 6 between which is a lever 8 pivoted at 9 carrying a cross-bar 12 through which the end of rod 7 passes. Upward movement of handle 4 causes rod 7 to close the jaws 24, 25 against the bias of spring 37. To disengage bayonet-joint 46, 47 and detach the head, member 16 is rotated against torsion spring 18 by release lever 19 on rod 7 and the handles and arm 2 withdrawn. Square-section shank 42 prevents rotation of member 41. On re-engagement of coupling members 16 and 41 member 16 rotates against the pressure of spring 18 as face 48 of recess 47 contacts projection 46. Holes 56 on socket 23 enable the head to be mounted on a suitable rack or support (54) and a different head fitted. This is of particular use when handling radio-active materials when the arm portion 2 (Fig. 2), may pass through a balljoint 51 in a lead shield 53 and the operating heads are retained within the shield. The handles 3, 4 and hence jaws 24, 25 may be retained in a closed position by engaging the portion 63 of stirrup 61 with serrated surface 65 on the handle 4. An adjustable handle, Fig. 3, may be fitted pivoting on a pin 86 and lockable in position by butterfly nut 77. The arm may comprise a number of sections connected together at angles to each other and the operating means may comprise a plurality of rods connected by one or more pivoted levers. Specifications 632,621, 739,209 and 931,443 are referred to.

Filed: 1950-06-15
Abstract: 704,667. Preparing fibres for spinning. MOSES, A. S. June 15, 1950, No. 14994/50. Class 120(1) Fibre - producing plants are decorticated b y subjecting the plant to repeated impact delivered by a rotating element without appreciable scraping action, while it is being held against. substantial movement in the direction of the fibres, the plant being repeatedly thrown by the rotating element radially thereof against a fixed shield which is spaced from the rotating element a distance substantially greater than the thickness of the fibre of the plant: As shown, leaves to be decorticated are fed by travelling belts 48, Fig. 1, until. they are gripped near the middle by endless chains the upper of which passes over sprockets on shafts 34, 36. The right-hand portion of each leaf is carried forward by an endless belt 50, while the left-hand portion is carried by a spiked conveyer up a conical guide 26 so as to pass' beneath the flared front edge 25 of a shield 20 to be decorticated by a rotary drum 17 having blades 19 and a tapered forward end. Shield 20 conforms to the drum for a part of the circumference and has a substantial clearance from the rounded tips of blades 19 so that the leaves are sub-. jected to a beating, not a scraping action. The decorticated portion of the leaf passes down a conical guide 27 at the end of drum 17 and is gripped between a second pair of endless chains passing over sprockets on shafts 34, 38, the undecorticated portion of the leaf being carried up a second conical guide 26 to be treated by a second drum 18, similar to drum 17. The decorticated leaf to the left of the gripping chains is carried forward on an endless belt 54. The completely decorticated material L is delivered on to a bar 101 on which it hangs. The chain links 29, Fig. 6, are guided by angle bars 22, 28 and have interfitting fingers 31. Belts 56, passing around a roll 57, Fig. 1, lie between the fingers 31 of the upper chain alongside drum 18. Circumferentially ribbed crushing rollers may be provided in front of either drum. The machine frame may be the chassis of a vehicle.

Title: Improvements in and connected with hydraulically operated soot blowers
IPC: F28G3/16
Filed: 1930-05-15
Abstract: 347,901. Boiler cleaners. BABCOCK & WILCOX, Ltd. and JONES, E. W., Babcock House, Farringdon Street, London. May 15, 1930, No. 15030. [Class 99 (ii).] A soot blowing system for boilers comprises a number of elements 9, rotated successively by fluid pressure acting on pistons carrying racks 7 meshing with pinions 8 secured to the elements. A pressure cylinder is mounted on each side of each element to effect rotation in either direction. Water from the boiler feed pipe, economizer &c. passes through a cooling tank 22 to a hand operated distributing valve 17, which is turned to the position shown in Fig. 3a. Pressure acting on the piston 5<1> causes the element 9 to rotate until the port 14 is uncovered and fluid escapes to the next unit. The descending piston 4<1> forces exhaust fluid through the pipes 16, 16<1>, 26 to the exhaust pipe 28. This operation is repeated until all the elements have been rotated in one direction, the distributing valve is then reversed and the elements rotated successively in the opposite direction. A needle valve 31 controls the fluid supply and hence the speed of working. In a modification this valve is operated by a rotating cam causing the supply to be intermittent and preventing seizure of the working parts. Steam is supplied to each blower through a valve 10 actuated by a cam 11 detachably connected to the element which can thus be readily isolated.

Abstract: 696,162. Gas-blast switches. CESKOSLOVENSKE ZAVODY TEZKEHO STROJIRENSTVI, NARODNI PODNIK, and HOUST, F. June 25, 1951 [July 15, 1950], No. 15069/51.Class 38 (v) In a gas-blast switch, such as that of Specification 644, 947, having a rotary blade structure or turbine runner for arc-extinction purposes, a supply of compressed air is provided to start the runner rotating before the contacts of the switch separate. In the example shown, the switch has the runner 12 surrounding an arc chamber 11 which may be of gas evolving material and carry fixed arc horns 10. The "moving" contact 4 is actuated by a piston (not shown) and the "fixed" contact 5 is biased by a spring 6, so the switch is opened, the contact 5 can follow the movement of the contact 4 to a limited extent to provide the delay period necessary for the runner to start turning before the contacts separate. Thus when the switch is closed the interengaging surfaces of the contacts are at 19. To open the switch, compressed air is applied to the operating piston of the contact 4 and through a pipe 18 to start the runner 12. The contact separation occurs when the contact 5 is arrested with its contact surface at position 9, the arc drawn being transferred to the arc horns 10 as the end of the contact 4 moves to position 20. As the contacts separate, an extinguishing blast of compressed air may be applied through a pipe 17.

Abstract: 1,074,543. Gear cutting. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUTE VGOLNOGO MASHINOSTROENIJA. June 14, 1964, No. 15331/64. Heading B3K. [Also in Division F2] In a globoidal worm gear, the speed at which the line of contact 1<SP>1</SP>, 1<SP>1</SP> &c. between the worm thread and the wheel tooth travels across the face of the wheel tooth is increased in comparison with that obtaining in an unmodified gear by smoothly varying the circular lead of the worm thread. Thus, in Fig. 2, the contact line of an unmodified gear travels from 1<SP>1</SP>, 1<SP>1</SP> to 4<SP>1</SP>, 4<SP>1</SP> at a velocity V 2 <SP>1</SP>, whereas for the modified gear, Fig. 3, the contact line travels across the whole face of the wheel tooth from 1<SP>11</SP>, 1<SP>11</SP> to 7<SP>11</SP>, 7<SP>11</SP> at a speed V<SP>11</SP> 2  which is greater than V 2 <SP>1</SP>. The wheel teeth are generated by a hob which either corresponds to the modified working worm so that full width tooth contact is immediately obtained, or alternatively the hob may, in comparison with the working worm, have thread relief extending from zero at its mid-length to a maximum at its ends (Fig. 6, not shown). In this latter case, in operation of the assembled gear, contact initially occurs at the central zone only, but, during running-in, extends eventually over the whole tooth face as before. Preferred curves for the variation of the contact-speed V 2 11 are specified (Fig. 4, not shown), and it is stated that the variation is dependent on the law of variation of the circular lead of the worm. The law is not specified. In addition, the diminishing thread at the entry end of the worm has the tip (10), Fig. 5, not shown, of its flank relieved over a spiral zone beyond the working zone (9) of the flank.
