Title: Well head assembly
Inventor: RAULINS GEORGE MAX
IPC: E21B33/038
Filed: 1962-10-10
Abstract: 992,347. Wells &c. OTIS ENGINEERING CORPORATION. Oct. 10, 1962, No. 38295/62. Heading E1F. [Also in Division F2] A well head assembly includes a coupling 10, for attaching to a tubular member 13 (e.g. an underwater well head) having circumferential ribs or threads 115, comprises a tubular body carrying latch means 38 resiliently engageable with threads 115 and locking means movable between a position in which the latch means are radially movable and a position in which radial movement is prevented. Fig. 3 shows latch means comprising a collet with fingers 38 which can be pushed over threads 115 while a locking sleeve 80 is held by a shear screw 102. Screw 102 is sheared by pumping fluid into a chamber 128, and the sleeve moves to prevent flexing of fingers 38. To unlock the coupling fluid is forced into a chamber 130 to withdraw sleeve 80, or the coupling may be unscrewed from member 13, since the bosses 110 on fingers 38 form a thread. Sealing between member 13 and coupling 10 is by means of an inner sleeve 50 carrying a seal means 65 and a seal assembly 70, engaging the surface 122 of member 13. When the coupling and member engage, a slide ring 74 engages a shoulder 120 and the seal assembly 70 is compressed. When the chamber 128 is filled, a pressure chamber 60 is filled also, through a port 56, depressing the inner sleeve 50 and improving the seal, and the pressure may be increased should high well pressures cause leakage. The fluid used may be a thermo-setting or time-setting material, so that pressure need not be maintained. Figs. 4, 5 (not shown) illustrate a similar coupling, in which the collet fingers fit inside the tubular member, and a single internal sleeve serves for locking and sealing. Fig. 7 shows a coupling having latch means comprising dogs 306 urged radially inwards by a garter spring 312 to engage ribs or threads on a member 13, and being locked against outward movement by a locking sleeve 360. Should the sleeve be held by set material, in the case of a member 13 having discontinuous circumferential ribs, de-coupling is achieved by rotating the coupling so that the dogs coincide with gaps in the ribs.

Title: Stapler for manufacturing folded boxes or similar work pieces
IPC: B31B50/68
Filed: 1960-11-09
Abstract: 928,723. Stapling-machines. H. LINDEN. Nov. 9, 1960, No. 38554/60. Class 89 (3). [Also in Group XVII] In a stapler for making folded boxes or similar workpieces which is switched on by an electrical contact influenced by a workpiece 12 as it is fed in, stops 18, 19, 20, 21 are provided which can be variably spaced in the direction of feed and which are arranged to interrupt feeding at predetermined points by electronic means, the workpiece being arrested when the stops are engaged thereby, the stops being removed from the feed path as stapling proceeds. The stapler, having a head 25, is driven by an electric motor 111 incorporated into the electronic control system. The stops 18 to 21 are movable into their operable position by a controllable detent element, preferably a pawl 53 retained in its locking position by springs 51 and removable therefrom by an electromagnet 58. A stop may be constituted by a pair of mutuallyconnected pins 43, 44, moved to be inoperative by a beam 61 which swings up and down in rhythm with the stapling mechanism, and are carried by a guide-plate 49, detachably secured via a screw 50 to a support 17 which runs in the feed direction and carries the pawl 53 and associated magnet 58, to form a stop assembly. The beam 61 causes the pins 43, 44 to be withdrawn enough for the pawl 53 to re-engage a toothed member 54 secured on a cross-member 47 carrying the stop-pins 43, 44, which are thus prepared for the next work stage. The beam 61 is conveniently controlled by an eccentric shaft 66 which simultaneously actuates the stapling mechanism, the eccentrics doing this being staggered as far as the timing of their instant of maximum throw is concerned relative to the eccentric which via a lever linkage 64 moves the beam 61, which moves downward for withdrawal of the stop only after the driving-in of a staple. The magnet 58 is included in the anode circuit of a hot-cathode triode valve, the negative grid voltage of which is removed upon flashing of series-connected cold-cathode valves, which thus allow the current to flow to the magnet 58. The flashing of the cold-cathode valves is effected by an impulse switch operating synchronously. After stapling, with which is associated the folding of the workpiece 12, in a known manner, it is fed in the direction of the arrow (Fig. 1) by means of belts 15, 16, running over rollers 13, 14, from the stapler head 25, where it is loaded by a hold-down belt 32 running over rollers 30, 31, rotatably mounted on an arm 33, rockable about the point 34 at the end of an arm 35, rockable about an axis 36. At the end of the belt 16 is a light-beam barrier 37 for counting the pieces 12, after which they run through rollers 38, 39 and 38, 39<SP>1</SP>. Initially the workpieces 12 cut-to-size are laid one upon another at the entry side of the machine to form a stack supported by a receiving plate, the top piece of which is roughly level with the belts 15, 16, by means of lifting apparatus for the plate controlled by a photo-electric cell in conjunction with a lamp.

Title: Control circuits for discharge lamps
IPC: H05B41/04
Filed: 1971-08-17
Abstract: 1364928 Supply circuits for discharge lamps NOVANEX AUTOMATION NV 17 Aug 1971 [19 Aug 1970] 38600/71 Heading H2H A discharge lamp supply circuit comprises a triac 15, the control electrode of which is supplied with a control voltage from a timing circuit including a capacitor 21 and a resistor 22, a series arrangement of a resistor 24 and a capacitor 25 being connected in parallel with the resistor 22. Terminals 11, 12 of the circuit are connected to heatable filaments of the discharge lamp and the circuit enables a starting pulse to be supplied to the lamp at the beginning of each half cycle of an A.C. supply. The operation of the circuit is similar to that described in Specification 1,347,408. Each high voltage starting pulse switches the lamp on for a period in each half cycle during which the triac is non- conductive. The brightness of the lamp is therefore controlled by adjusting the resistor 22 to vary the firing point of the triac. When the triac conducts it reduces to zero the voltage across the lamp but allows heating current to flow through the filaments. In a modification, Fig. 8 (not shown), the resistor 22 is fixed.

Filed: 1959-11-16
Abstract: 862,703. Concrete piles. RAYMOND INTERNATIONAL Inc. Nov. 16, 1959 [March 17, 1959], No. 38688/59. Class 68(2). A concrete preparatory shell for a cast-in-situ pile is formed by driving into the ground a casing 32 and a mandrel 31, both resting on a driving shoe 33. Wet concrete is then poured into the space between the casing and mandrel, the casing is removed and a tapered cylinder 36 is driven along the mandrel to expand the concrete into contact with the walls of the hole. The cylinder 36 has a gasket 38 which wipes the mandrel clean, so that it can be removed and immediately re-used. The cylinder 36 is removed after the concrete has set and the central hole is filled with concrete. In a modification (Fig. 6) the cylinder 36 is replaced by a parallel or slightly tapered cylinder 45 with a ring 46 attached thereto, which forces the concrete 43 radially outwards as the cylinder 45 is drawn down over the mandrel 40. The ring 46 remains in the bore when the cylinder 45 is removed. In a second modification (Fig. 10) a cylinder 64 with a ring 65 formed at its lower end is positioned around the mandrel before the concrete is poured, and expansion of the concrete is effected by raising the cylinder 64. One or more vibrators may be used with this modification. In a third modification the method is used to construct a composite pile which comprises an upper concrete section 81 and metal sections 82 and 83. The metal sections 82 and 83 are secured to a driving ring 86 which carries a casing 87 and a tapered cylinder 88. The assembly is driven by a stepped mandrel 85 acted on through a helmet 90. Concrete 81 is placed either before or after driving and is supported until it sets by a tapered cylinder 88 so that the mandrel 85 may be removed for further use.

Abstract: 1347126 Vehicle headlamp WESTING- HOUSE ELECTRIC CORP 18 Aug 1971 [1 Oct 1970] 38723/71 Heading F4R [Also in Division H1] A vehicle headlamp comprises a unitary concave reflector having an inner surface defined by two hemiparabolic reflector segments which are displaced from one another in a longitudinal direction and merge in a step along the medial plane of the reflector and has a light source located between the foci of the segments such that light rays from the segments give two superimposed beams of equal intensity. In an embodiment (Fig. 2) a moulded glass reflector 15 having a coating of aluminium has a filament 20 located between the foci F 17  and F 16  of the hemiparaboloids 16, 17. The angle of convergence α of the beam from segment 16 is the same as the angle of divergence # of the beam from segment 17 and thus two superimposed beams are produced (Fig. 1, not shown). The stepped reflector may be used in association with a tungsten filament (Fig. 2) or a quartz halogen light source (Figs. 11, 12 and 15, not shown) and may form part of a sealed-beam lamp (Figs. 4, 5a, and 12, not shown) or be formed from a pressed-metal sheet and have a translucent cover (Fig. 15, not shown). The filament may lay across (Figs. 4 and 5a, not shown) or along (Figs. 12 and 15, not shown) the optical axis of the reflector. The centre of the filament may be off-set to one side of the optical axis (Fig. 5b and 6, not shown) and may be raised above the horizontal medial plane of the reflector (Fig. 5c, not shown). In another embodiment, Fig. 3, the focal lengths of the segments 16a, 17a are unequal, the optical axis of segment 16a coincides with the geometrical axis X-X of the reflector but the optical axis O-O of segment 17a is set at an angle to the axis X-X. In some embodiments a fully or partially vertically fluted translucent member is used to close-off the lamp. The flutings may be evenly distributed across the member (Fig. 10, not shown) or of differing width and radii (Figs. 14 and 14b, not shown) for use in fog lamps. Where a partially fluted member is used, Fig. 13, the periphery 51 may be amber. Lighting systems utilizing the above lamps comprise four headlamps on the front of a vehicle grouped in two pairs on a horizontal line (Fig. 7, not shown) the outer lamp of each pair (38) comprising a single beam lamp, one of the other lamps (40) comprising a spot lamp and the other (22a) comprising a dual-segment lamp. In another lighting system (Fig. 16, not shown) two sets of three headlamps are used, a headlamp (65) on either side having a dual-segment reflector, the other headlamps having single or dual filaments.
