Title: Horizontal well pipe rack
IPC: E21B19/15
Filed: 1970-09-16
Abstract: 1308216 Boring earth &c BYRON JACKSON INC 16 Sept 1970 [22 Oct 1969] 44135/70 Heading E1F Apparatus for horizontally racking drill pipes 5 comprises spaced posts 27-32, and vertically movable beams 39a-39g mounted on each post. In the double section installation shown the posts of section B are opposed by posts 21-26 and beams of section A. In a section the pipes are racked in horizontal rows, spacers 43 on the beams resting on the pipes, and the lower row being supported by beams 38 fixed to the posts. On each post the movable beams are connected to one another by bolts 42, the arrangement being that the beams 39a are raised by hydraulic cylinders 46 to free the upper row and further raising of the beams 39a entrains the beams 39b-39g in turn until all the rows are free. The beams 39b-39g have fingers 53 onto which conveyors move pipe from a freed row for pickup by a transfer device, the fingers being moved by individual pneumatic cylinders automatically into a vertical position as the beams are raised. All fingers in a section may be moved into the vertical position when the beams of the section are in the lower racking position if it is desired to operate the other section. In a modification each of the beams are moved by a separate hydraulic cylinder, the spacers are shaped to engage the next lower beam, and the spacers have pivoted lugs spring loaded to lie horizontally and formed to steady pipe of different sizes.

Abstract: 1341309 Semi-conductor devices BROWN BOVERI & CO Ltd 27 Sept 1971 [29 Sept 1970] 44871/71 Heading H1K A semi-conductor unit is assembled by first attaching a clamping device 11 to a cooling block 2 as shown and using it to clamp yoke 8 against an abutment formed by the rim of a cup 9 located in a recess in block 2 and containing dished spring washers 10. A semi-conductor device 1 and second cooling block 3 are then attached by bolts 6, 7 which engage threads in the yoke and the heads of which bear on block 7 via insulating spacers 12, plain washers and the spring washers 13, which can be compressed an amount equal to the desired room temperature clearance between the yoke and abutment 9. The bolts are tightened so as just not to compress spring washers 13. On releasing the clamping device the resilience of spring washers 10 raises the yoke giving the required clearance and fully compressing washers 13 Spring washers 13 could alternatively be disposed under nuts threaded on bolts 7 which would then slide in yoke 8.

Abstract: 1,123,412. Threading tape recorders. WARWICK ELECTRONICS Inc. 26 Oct., 1965 [26 Oct., 1964], No. 45277/65. Heading G5R. A tape T from supply reel 30 is fed manually into guide channel 144 where a roller 156 drives it forward past capstan 42 to be gripped frictionally by take-up roller 28. Tape threading is initiated by clockwise rotation of shaft 82 which causes, through links 88, 113 and bell crank actuator 34, the release of brake 32. Slide 96 is also moved upwardly so that pressure roller 52 is brought into contact with capstan 42, Fig. 3. Solenoid 80 is energized to rotate the mounting of resilient drive wheel 156, Fig. 2 (not shown), against return spring 178, into the operative position. The wheel, driven by belt (164) from the capstan flywheel, engages the tape and passes it along the guide to the capstan and thence through guides 188, 190 to be led by arm 288 to the tape up spool 28, which has converging surfaces to grip the tape, Fig. 5 (not shown). When the tape is gripped by the spool, Fig. 4, it causes sensing finger 94 to rotate and operates slide 206. This releases backing member 54 and allows it to press the tape against the heads in the assembly 38. An end of tape sensing mechanism, Fig. 8 (not shown) is rendered inoperative during the threading process, and becomes effective when slide 206 is displaced to the left. A fast wind or rewind may be effected by rotation of shaft 56, but this is prevented during a record or playback period by slide 62.

Title: Improvements in and relating to Switching Circuits
IPC: H03K17/60

Abstract: 1,164,167. Transistor current switching logic circuits. INTERNATIONAL BUSINESS MACHINES CORP. 13 Oct., 1966 [14 Oct., 1965], No. 45731/66. Heading H3T. The threshold of a current-switching type transistor logic circuit is varied in the same sense as the input signal but with a time delay. In the embodiments the reference signal is constituted by a delayed and reduced amplitude version of the input signal (Fig. 6) so that switching action at V and W takes place more quickly after the beginning of the pulse than when a fixed mean-value reference is used. A further increase in speed of response may be obtained by providing positive feedback to the reference potential so that, as in Fig. 28, the reference initially moves towards the input potential. The delayed attenuated signal may be obtained from the output (Fig. 2, not shown) or from the input (Fig. 17, not shown). In Fig. 1 the current switching logic circuit comprising a plurality of input transistors Q1, Q1n sharing a common emitter load with transistor Q2 and feeding an output stage Q3, Q4. A voltage of the same sense of the input signal but of reduced magnitude is obtained from resistors R4 and R5 and applied as the reference voltage to transistor Q2, the delay of the reference voltage being provided by inherent delays in the circuit, assisted if necessary by capacitance at point 22 (C1, Fig. 15, not shown). The reference voltage may alternatively be obtained from a potentiometer connected between the collector of Q3 and earth (Fig. 22, not shown) or, via a further transistor, from the collector of Q4 (Fig. 23, not shown) or from the emitter of Q4 (Fig. 25, not shown). The positive feedback required by Fig. 28 type circuits may be obtained by means of a capacitor or a resistor connected between the collector of Q1 and the base of Q2 (C3 or R85, Figs. 26 and 27, not shown). In Fig. 24 (not shown) the push-pull output stage is replaced by a single transistor (Q36) providing the delayed reference voltage from a potentiometer (R64, R66) connected to the collector. In a further embodiment (Fig. 16, not shown) the delayed reference voltage is obtained by feedback from the collector of Q2 to a capacitor in its base circuit (Q22<SP>1</SP>a and C2, Fig. 16, not shown). A pulse oscillator may be formed by coupling the output of transistor Q4 via a delay line to the input of transistor Q1 (Fig. 14, not shown).

A liquid spraying device suitable for coating vehicle bodies, roofs and doors &c. with paint and of the type comprising a housing 10, a liquid inlet 12, an air inlet 34, a passage 13 in the housing connecting the inlet 12 to a liquid nozzle 14, a needle valve 15 controlling the liquid flow, passages 48, 54, 56 connecting the inlet 34 to an air nozzle 23 surrounding the nozzle 14, passages 48, 49, 53 connecting the inlet 34 to an air nozzle 29 adapted to flatten or otherwise shape the stream of atomized liquid issuing from the nozzle 14, and air valves 31, 32 controlling the flow of air to said passages, is provided with a common operating trigger 59 for the valves 15, 31 and 32, the arrangement being such that the trigger 59 is movable to increase the air supply to the nozzle 29 and simultaneously to increase the supply of liquid to the nozzle 14 without substantially altering the supply of air to the nozzle 23. Actuation of the trigger 59 first opens a closure member 35 of the valve 31 against a spring 38 and air pressure by moving its spindle 36. Air thus flows through passages 50 and 48 and is divided between the nozzles 23 and 23 according to the adjustment of a rod 57. On further movement the trigger moves an adjustable actuating member 18 against a spring 20 so as to displace the needle valve 15, and when the trigger is fully retracted it opens the valve 32 and additional air flows to the nozzle 29 through a passage 49, Fig. 3, under the control of a rod 58 and the liquid flow is increased to a maximum.
