Abstract: 1,260,356. Underwater connecting of pipe-lines. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 18 June, 1969 [20 June, 1968], No. 30769/69. Heading F2P. A method for the underwater connection of two pipe-lines 5, 23, using manipulating and joining apparatus 24, comprises marking the location of the free end of the pipe-line 5, pulling the pipe-line 23 adjacent to the location, attaching the pipe-line 23 in a predetermined, fixed position on the manipulating and joining apparatus 24, lowering the apparatus 24 to the free end of the pipe-line 5 so that the pipe-line 23 overlaps the pipe-line 5, cutting-off the overlapped portion of one of the pipe-lines, so that the ends of the pipe-lines lie in the same vertical plane, and coaxially aligning and joining the ends. The pipe-line 5 extends from a well 2 and the location of its free end is marked by a buoy (8) attached to a guide line 7 attached to the free end by means of a plug (7a), Fig. 5 (not shown), sent down the pipe-line 5 to the free end. A pipe-lay barge 22 pulls the pipe-line 23, extending from a gathering station 9 or a production system, to the buoy 8. The pipeline 23 is affixed to the manipulating and joining apparatus 24 and the apparatus 24 is lowered down the guide line 7 by means of control lines 28, 29, to the pipe-line 5. The overlapped portion of the pipe-line 5, including the plug (7a), is cut off and the pipe-lines 5, 23 are joined by the apparatus 24 by means of arc, gas or resistance butt-welding, the operations being remote controlled from the barge 22. Alternatively the overlapped portion of the pipe-line 23 is cut off above the surface of the water after television cameras in the apparatus 24 have recorded the amount of overlap of the pipe-lines 5, 23.

Abstract: 806,820. Lathe-details. NATIONAL ACME CO. Oct. 10, 1956, No. 30883/56. Class 83 (3). As described with reference to a six-spindle turret-lathe, bar-stock is machined at one end in positions 1, 3, 5 of the turret, is removed from spindle 5, reversed, and inserted in spindle 6, the other end of the work being completed at positions 2, 4, and the finished work being ejected at position 6. At position 5 (spindle 18, Fig. 3), the work 20 is engaged by rollers 28, 29, 31, the two former carried by a block 24 pivoted at 26 on a holder 16, and the latter carried by a block 25 pivoted at 27. Springs 30, 32 press the rollers towards the work 20. Holder 16 has a shank 23 pivoted in a member 15 attachable to a cross-slide 12 of the lathe, the action being such that on completion of machining in spindle 18, the slide 12 is advanced, a pin 37 on block 25 engaging a fixed cam 38 to lower roller 31 and allow the rollers to embrace the work and support it during cutting- off by a tool 11. The holder 16 is then rotated about its shank 23, through a pinion 40 on the shank engaged by a rack 41 operated by a rod 42 actuated from a cam (not shown), by a lever 43 and cushioning springs 44, the work being thereby inverted and brought opposite spindle 19, into which it is pushed by a camoperated rod 49. The holder 16 and slide 12 are then withdrawn and the holder oscillated to its original position in relation to spindle 18. The closure of the rollers is limited by stops 33, 34 in blocks 24, 25 engaging screws 36, 35 in the holder. The spring 44, Fig. 1, assists alignment of the rollers by allowing the rack limited-free movement, and screws 45, 46, Fig. 3, on the holder contact stops 47, 48 to effect alignment of the holder with the spindles 18, 19 respectively. Specification 410,135 is referred to.

Title: New or improved self driving engine or machine
IPC: F03G7/10
Filed: 1920-11-02
Abstract: 173,929. Slater, T. Nov. 2, 1920. Self-driving machines.-A self-driving engine comprises a casing divided into two chambers 26<a>, 26<b> which are filled with liquid. The liquid in the upper chamber 26<a> is pumped into the lower chamber 26<b> by a hand pump B until sufficient pressure is obtained, and the valve 29 is then opened to allow the high-pressure liquid to drive a piston 4 operating in a cylinder 2. The liquid is distributed to the cylinder or cylinders by means of pairs of oscillatory valves 11, 12 having inlet and discharge ports 13, 14 registering at intervals with ports 15, 15<a> respectively, the discharged liquid being returned to the upper chamber by pipes 68, 69. The piston drives the shaft 9 by crank and connecting-rod, and the oscillatory valves are operated from the same shaft by means of eccentrics, a link motion and rack 20 co-operating with teeth 19 on the valves. Rods 47 operate counterbalanced levers 41 which drive pump A to maintain the pressure in the lower chamber 26<b>. If the pressure in the lower chamber is. too high, the pressure is relieved by a valve C, and if the pressure is too low a piston 54 moves under the action of a spring and draws the rods 47 to the position shown, thereby lengthening the stroke of the pump A. In a modification, the lower chamber is dispensed with, and the liquid from the pumps A is delivered direct by separate conduits to an overhead tank, the head of liquid supplying the required pressure while the stroke-varying means is operated by hand. In a further modification, the separate conduits from each pump A are omitted and the pumps deliver to a chamber from which the liquid is forced to the overhead tank by a single conduit. The Provisional Specification describes three chambers in place of the two chambers 26<a>, 26<b>.

Title: Improvements in or relating to Pulse Generators.
Inventor: HAYASHI TOSHIYA
IPC: H01L47/00
Filed: 1967-07-10
Abstract: 1,196,045. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. 10 July, 1967 [11 July, 1966 (2)], No. 31618/67. Heading H1K. [Also in Division H3] A pulse generator operates by producing travelling electric field domains in a two-valley semi-conductor specimen 12 where geometry, resistivity distribution, contact system &c. are such that an applied voltage sets up a non- uniform field in the specimen. The circuit of the generator includes a source 16 of sufficient voltage to set up a domain-triggering field in the specimen and is such that the travelling domains can provide two sets of output pulses. In one arrangement, the output is a train of pulses as shown in Fig. 5, the two sets of pulses (i.e. one set comprising the pulses 18 and the other the pulses 19) being interleaved. In another arrangement the circuit can produce either a set of pulses of one kind, e.g. a given pulse repetition rate, or a set of another kind (different repetition rate) but not both together. In Fig. 1, the field is made non-uniform by the presence of the N+ region 15 and each domain initiated at one terminal of the specimen produces in the output circuit a large amplitude pulse 18 when it is extinguished at the other terminal and a smaller amplitude pulse 19 as it traverses the portion of the specimen containing the region 15. In Fig. 2 the specimen geometry is such that the applied voltage may be sufficient to set up a domain-sustaining field in only the portion 31A of least crosssection or, if the voltage is increased, domains can traverse the full length of the specimen. The circuit can thus produce one or the other of two different pulse repetition rates in dependence on the magnitude of the energizing voltage. Figs. 3, 4 and 6 (not shown) depict circuits in which the specimen has one or more ohmic or rectifying contacts in addition to the terminal contacts. By applying suitable potentials to such extra contacts, or by shortcircuiting them to one of the terminal contacts, the output pulse repetition rate may be changed. In the case where the potential on an auxiliary rectifying electrode provides the frequencyselective control (Fig. 6), the specimen is analogous to a field-effect transistor.

IPC: B23Q27/00
Filed: 1964-08-04
Abstract: 1,068,479. Grinding. BIRFIELD ENGINEERING Ltd. July 30, 1965 [Aug. 4, 1964], No. 31728/64. Headings B3B, B3D and B3K. [Also in Division F2] The tracks in the inner or outer member of a constant velocity universal joint are machined by rotating the member about its own axis and traversing a cutting tool longitudinally of the member with a simple harmonic motion the amplitude and periodicity of which is so related to the speed of rotation of the member that the tracks machined by the cutting tool all lie, in developed view, on a common sinusoidal curve. For grinding internal tracks in the outer member 27 of a constant velocity universal joint the member 27 is clamped to a workhead 25 rotatable in bearings 26 in a headstock 21. The workhead is rotated, through worm gearing 24, telescopic flexible coupling 23, drive shaft 22, pulley 28, and belt, by an electric motor. A reciprocatory cutter head 35 supports a motor 37 driving, through belts 39, 40, a vertical spindle 38 on which is mounted a profiled grinding wheel 43. The spindle 38 is carried by a bracket 44 which can enter the workpiece and is vertically adjustable by a hand-feed spindle 46 to adjust the depth of cut of the grinding wheel 43. The drive shaft 22 carries a gear 30 meshing with a gear 32 having a crank-pin 34 engaging a slide 46 movable in a slot 47 in a drive member 48 connected by a pin 49 to the cutter head 35, which is thus reciprocated with a simple harmonic motion. To produce six circumferentially spaced tracks, the tooth ratio of the gears 30, 32 is so matched to the reduction ratio of the worm gearing 24 that the gear 32 makes three complete revolutions for each revolution of the workpiece. For grinding external tracks on the inner member, the headstock 21 is raised by interposing a distance piece between it and the machine bed 20. The amplitude of the reciprocation is chosen to give the desired crossover angle of the inner and outer tracks. A milling cutter may be used instead of the grinding wheel 43.

[Also in Group XXXIV] To effect variation of the track width of a tractor by power rotation of the axle, a tractor wheel comprises a body disc 18 secured to a hub 17 and having a radial split 19 so that the disc periphery 20 defines a helical path to co-operate with means 22 on the rim 12 whereby relative rotation of the disc and rim results in axial movement of the rim on the disc. As shown, the disc edge 20 is reinforced by a split ring 28 which engages in rectangular-section notches 25 in a series of equi-spaced transverse bars 22 secured to the inner periphery of the rim 12. Each bar 22 has a number of notches 25 therealong, interspaced by wedge-section notches 26, corresponding notches 25 of the series of bars 22 being relatively axially displaced to conform with the helix of the disc edge. The rim and disc are clamped in the desired relative axial position by blocks 30 bolted to the disc edge ring 28 and having a sloping surface 33 to wedge against corresponding sloping surfaces of the notches 26, tilting of the blocks 30 being prevented by wedge engagement with brackets 36 welded to the ring 28. To prevent detachment of the rim from the disc, two stop-plates 38 are bolted to one of the bars to cover respectively the extreme outer notches 25.
