Title: Mechanisms for disengaging and engaging the drive connection between a rotating cam disc and a cam follower normally in engagement with the cam disc
IPC: F02M39/02
Filed: 1974-07-30
Abstract: 1439427 Fuel injection pumps; engine stop gear; decompression devices BURMEISTER & WAINS MOTOR OG MASKINFABRIK OF 1971 AS 30 July 1974 [3 Aug 1973] 33592/74 Headings F1A and F1K A cam-operated guide 6 for reciprocating a fuel injection pump plunger or an engine cylinder valve is provided with a mechanism for disengaging the guide's cam follower 8 from contact with its rotary cam 2, the mechanism comprising a cam member 14 secured to one end of a fluid operated slide 13, the slide being arranged to move the cam member 14 axially into the path of a bar 27 carried by the guide 6 and then to rotate the cam member 14 to a position in which it engages and lifts the bar 27. The slide 13 is mounted for movement within a fixed housing 12 and includes a sealing surface 22 which co-operates with the housing 12 to define therewith end chambers 43, 44. In Fig. 5 the slide 13 is in its retracted position, a switch valve 34 having just been operated to initiate disengagement of the follower 8. The operation of the valve 34 directs fluid to the chamber 43 to extend the slide 13. At the same time the opposed chambers 45, 46 of a ram 20 for rotating the slide are connected to atmosphere, the chamber 45 via a line 39, a port 33 and a passage 23, 24, 25 in the slide and the chamber 46 via a line 36, 37 connected to atmosphere through the valve 34. As extension proceeds a collar 15 on the cam member 14 passes under the path of bar 27 while the latter is nearing the end of its delivery stroke. On complete extension of the slide 13 the port 33 is subjected to the supply pressure in the chamber 43, whereby the chamber 45 is pressurized to extend the pistonrod 19 of the ram 20 and rotate, via a universal joint 18 and an arm 17, the slide 13. Since the cam member 14 is eccentrically mounted on the slide 13, the rotation causes the cam member fully to engage the bar 27 and lift the latter to disengage the follower 8 from the cam 2. On reversal of the valve 34, the slide is first rotated to the position shown whereafter a groove 26 aligns with the line 36 to pressurize the chamber 44. During the period in which the follower 8 is lifted by the cam 2, the shoulder 15 clears a step (29) on the bar 27 to allow retraction of the slide.

Abstract: 1,235,142. Ink ribbons. COLUMBIA RIBBON & CARBON MFG. CO. Inc. 17 July, 1968 [20 June, 1968], No. 33959/68. Heading B6F. A pressure-sensitive ink-releasing, duplicating ribbon is made by applying to at least one surface of a thin, ink-absorbent fabric, comprising filaments or threads, a continuous, thin, porous, sponge layer of thermoplastic polymer, which layer covers the filaments or threads exposed at the surface of the fabric and contains interconnected, gas-filled pores, and impregnating the fabric with a non-drying liquid ink. The fabric and sponge layer together form a duplicating ribbon that can uniformly meter ink to a copy sheet under the effects of imaging pressure. In the example, a conventional web of woven nylon typewriter-ribbon fabric is coated with a composition comprising toluene diisocyanate, adipic acid-ethylene glycol polyester, polyethylene glycol, triethylamine and water, and passed through a drying tunnel where the composition forms a foamed polyurethane. The coated fabric is then passed to the nip of inking rollers which apply an ink comprising oleic acid, carbon black and nigrosine black. Reference is also made to the use of pigments of magnetic iron oxide, particulate dyestuffs and colourless colour-reactive chemicals.

Abstract: 1283198 Furnace linings BRITISH IRON & STEEL RESEARCH ASSOCIATION 3 July 1970 [7 July 1969] 34164/69 Heading F4B A blast furnace lining is formed from horizontal annular courses of elongated refractory blocks, opposed side faces 1, 2 of which, when the furnace is cool, lie in vertical planes parallel to but not including the vertical furnace axis, the blocks being laid up such that the longitudinal axis, e.g. y 1 -y 1  of each of the blocks makes an angle # with the associated furnace radius, e.g. 20. Expansion of the blocks on heating up of the furnace, is taken up (Fig. 5, not shown) by the blocks pivoting about vertical axes parallel to the furnace axis, near to their curved ends 4, so that the angle # tends to diminish towards zero. Preferably, the inner ends 3 of the blocks make angles # with lines, e.g. x-x perpendicular to their longitudinal axes, so that by aligning the ends 3 of the blocks initially during their laying up, their correct positioning to allow for expansion is attained. Alternatively (not shown), the blocks may be laid with the planes of their convergent surfaces 1, 2 coincident with the vertical furnace axis, but being inclined upwardly or downwardly to the horizontal at an angle #, so that they may pivot in a vertical plane to accommodate expansion. The angle # lies between 0 and 15 degrees and preferably equals 6 degrees.

Title: Improvements in or relating to chutes, for example, chutes for fueling nuclear reactors
Inventor: BELLINGER RONALD
IPC: G21C19/16
Filed: 1956-11-09
Abstract: 874,222. Handling nuclear fuel elements. STRACHAN & HENSHAW Ltd. Nov. 11, 1957 [Nov. 9, 1956], No. 34417/56. Class 39(4). A shoot for loading and unloading the fuel element channels in the graphite reactor core comprises an outer tube 2 insertable through a selected standpipe to serve a group of sixteen channels 8 the lower end of the tube having a thrust bearing member 4 locating in a hole at the group centre. The hole is provided in a charge pan 6 situated above the core and having openings corresponding to the fuel channels. Within the tube 2 and attached thereto at its upper end is an inner tube having an upper portion 16 and lower portion 18, the portion 18 being pivoted at 20 to the tube 2 and movable through a longitudinal opening 14 in the lower end of the tube 2, Fig. 1, from a position in which it lies wholly within the tube, Fig. 4B. The outward movement of the portion 18 to serve a channel 8 at a certain radial distance is effected by a link 24 connected between the portion 18 and the lower end of a longitudinally movable rod 22 situated between the inner and outer tubes. The link 24 is pivoted at 34 to the rod 22 and has rollers 31 guided in longitudinal slots 32 formed in the tube 2 whereby upward movement of the rod causes outward movement of the tube portion 18. This movement of the rod is obtained by a sleeve (Fig. 3, not shown) mounted on the upper end of the shoot about the shoot axis and coupled to the upper end of the rod 22, the coupling being such that rotation of the sleeve causes longitudinal movement of the rod. The entire shoot may also be rotated about its longitudinal axis to bring the portion 18 opposite the particular channel to be served. The means for rotating the shoot as a whole and also for rotating the sleeve are provided in a headbox surrounding the upper tube end, this headbox being described with reference to Figs. 3, 3A (not shown) and being similar to that disclosed in Specification 874,223. In operation a fuel element is lowered through the shoot by a grab from a charge/discharge machine. A modified shoot capable of extending over a greater radius for serving a greater number of channels (Figs 5-13, not shown) has its lower portion for extension through the longitudinal opening in the outer tube composed of two parts pivotally connected together. One of these parts corresponds to the portion 18 of the previous embodiment and the other part forms a continuation of the first part but is maintained in parallel relation with the outer tube by a linkage so that the other part is always vertically disposed above the selected channel. In a modified headbox (Figs. 14-16, not shown) the vertical movement of the rod 22 is obtained by a roller attached to the rod and running in a helical cam groove in a rotatable sleeve surrounding the shoot. Reference has been directed by the Comptroller to Specification 838,292.

The driving rods 3 are moved by a screw spindle 14 operating on one of the rods 4 and the motion being transmitted to the other jaws via a drive ring 6 and journals 4b. Each rod 4 has inclined teeth that engage with teeth on a respective jaw to produce radial movement of the jaws 3. During normal jaw movement the holding pin 7 is depressed against its spring 8 and a locking head 12 can be moved into a groove 4c in the drive rod 4. At the extremity of its movement the rod teeth become disengaged from the jaw teeth, but the groove 4c no longer is present beneath the locking head 12 and movement of the holding pin 7 to release a jaw 3 is prevented. Thus throw out of a jaw 3 by centrifugal force is prevented.

Filed: 1974-08-05
Abstract: 1483893 Discharging liquids by gaseous pressure A A SMITH 5 Aug 1974 [5 May 1973] 34454/74 Divided out of 1483892 Heading F1R [Also in Division F2] A hand-held sealing gun for extruding sealant or mastic material is operated by compressed air selfcontained in a chamber 12, Fig. 2, in the gun, and has a valve 2, Fig. 1, for controlling the extrusion of the sealant, the degree of opening of the valve being dependent on the pressure of the compressed air in the gun. The valve 2 comprises a hollow cylindrical member which is slidable in a passage in the gun, and which has a closed end 4 and a flap-controlled opening 5 adjacent the closed end. In order to compensate for the reduction in air pressure as the sealant is dispensed, to keep the rate of extrusion substantially constant, the flap 27 which is part cylindrical is spring-biased clockwise, Fig. 1, about an axis 28 against an oblique cam surface 29 of a slidable spring-biased member 30. As the air pressure drops the member 30 moves to the left thus enabling the flap 27 to move upwardly along the surface 29 and open further the inlet opening 5 of the valve 2. The compressed-air chamber is separated from a sealant chamber 10 by means of a flexible diaphragm 13. A trigger 1 for operating the valve 2 is biased by a spring 24 in one direction and acted upon in the opposite direction by the pressure of the compressed air via a pair of pistons (20), Fig. 3 (not shown), working in cylinders 21  and acting on the trigger through a yoke 22. The yoke and trigger are rigidly connected to a valveactuating rod 3.
