Patent GB-1266802-A (GB)
IPC: B66F9/18
Filed: 1970-02-03
Abstract: 1,266,802. Load-handling apparatus. G. A. YOKICH. 3 Feb., 1970, No. 5188/70. Heading B8H. Load handling apparatus comprises a mast 10 which may upstand from the front of a lift truck, on which an elevator 12 is mounted for upward and downward slidable movement under the action of an hydraulic ram 13. The elevator 12 carries a mounting structure 15 comprising a shaft 20 rotatably mounted in the elevator 12 and a tubular part 27 having a shaft 30 extending therethrough. A pair of gripping arms 16 are rotatably mounted on the shaft 30 by means of sleeves (37), Fig. 7 (not shown), the sleeves (37) and part 27 having coacting cam surfaces (38), (34) which cause outward and inward movement of the arms 16 when the arms are pivoted upwardly and downwardly, respectively, the sleeves (37) being biased inwardly by springs 40. Each arm 16 carries an adjustable leg 45 with an extension 50. The mounting structure 15, arms 16 and legs 45 are rotatable about the axis of shaft 20 and to effect this rotation the shaft 20 is provided with a pulley 55 and the mast 10 with upper and lower pulleys 56, 57 about which pulleys a cable 58 is trained. In operation of the device the elevator 12 is lowered to the ground whereupon the legs 45 raise the arms 16 to receive a drum 60. Upon raising the elevator 12 the arms 16 are swung downwardly and thus move inwardly under the cam-action to grip the drum 60. As the elevator 12 rises further the pulley 55 rises with it and when clamps (59), Fig. 2 (not shown), contact either of the pulleys 56, 57 the pulley 55 is caused to rotate upon continued movement of the elevator 12 thus tilting the drum 60 to permit its emptying while it is held by lips 52 on the extensions 50. The arms 16 are maintained in a horizontal position during their raising by means of horizontal pins (33) mounted on part 27 and corresponding recesses (44), Fig. 6 (not shown), in the arms 16 which also prevent lateral movement of the arms 16 during the tilting procedure.

The schematic diagram may represent an hydraulic system on operation of one of the first switches 16 or a fuel system on operation of another switch 16. Some switches 16 may cause the projector 22 to project a slide of a flight chart and pattern. In this case a plotting device 30 is pivoted from a counterbalanced upper position to the position shown in Fig. 3 where a transparent surface 36 of the device 30 is superimposed on the screen 24 and a pen 38 draws a trace of a simulated flight path on the surface 36 in response to signals from the computer. The slides may also display written instructions. Additional switches may be provided on the panel, Fig. 2, on which the first and second switches and the screen are mounted, such as switches for controlling simulated aircraft position, slew or weight distribution, or panel and projector lamp intensities. Specification 1,289,562 is referred to.

Abstract: 1308602 Revaporizing liquefied gases FOSTER WHEELER JOHN BROWN BOILERS Ltd 5 March 1970 [5 March 1969] 11777/69 Heading F4P An L.N.G. vaporizing plant for supplying a variable demand consumer line 18 comprises an L.N.G. storage reservoir 12 connected by a line 14 to an indirect heat exchanger 16 containing series connected hot water coils 20a, 20b supplied by a pump 26 which delivers through a heater 24 and draws from a water tank 30 to which the water leaving coils 20a, 20b, is returned at 28; the tank being located below the level of heat exchanger 16 so that when the pump causes to function the water drains from the exchanger 16 and the rate of flow of L.N.G. is responsive to the draw-off rate of vapour. Coils 20a, 20b are relatively located in the liquid and gas space of exchanger 16 and serve to first vaporize and then further warm the vapour prior to discharge into line 18 which contains a constant output pressure maintaining valve 38 and has a branch line 48 including a thermostatically controlled valve 44 for supplying the burner of water heater 24. In operation and assuming gas demand in line 18 to fall, the resulting temperature rise in the gas space of exchanger 16 and hence of a thermostat 52 results in arrest of pump 26, drainage of water from exchanger 16 and closure of a valve 44 by a thermostat 46. A subsequent increase in gas demand results in evaporation of L.N.G. in exchanger 16 followed by a fall in temperature so that thermostat 52 restarts pump 26 and thermostat 46 opens valve 44.

Abstract: 1309547 Tensioning hollow bolts and studs ENGLISH ELECTRIC CO Ltd 24 July 1970 [25 April 1969] 21195/69 Heading F2H Tensioning apparatus for a hollow bolt or stud comprises a member 3 attachable to the bolt or stud so as to close one end of the bore 2, a push-rod 7 for insertion into the bore to engage a reaction surface provided by or supported by the member, a fluid operated piston and cylinder 9, 14 removably attachable to the opposite end of the bolt or stud arranged such that the piston can engage the end of the push-rod which can thus be urged axially against the reaction surface by fluid pressure and so apply a compressive force to the pushrod and hence tension the bolt or stud. Push-rod 7 bears at one end against load spreader 27 in cap nut 3 and at the other end against piston 14 sliding in cylinder 9. Chamber 24 in cylinder 9 above the piston receives oil via inlet 22, and air is bled out via valve 23. Cup washer 18 held on piston 14 by nut 19 on stud 21 seals chamber 24 when pressure is applied to the oil in chamber 24 to apply stress to the bolt. Bush 10 enables cylinder 9 to be fitted to the desired size of bolt. Aperture 25 is for admitting a pin of a diameter which determines whether piston 14 has sufficient travel before contacting the top of bolt 1. In use, after the oil is pressurized, nut 4 is adjusted to take up the longitudinal strain. Instead of tensioning a bolt using a cap nut, the invention may tension a stud screwed directly into one of two or more members to be fastened.
