Abstract: 969,652. Masted lift trucks. LEWISSHEPARD CO. Dec. 5, 1961, No. 43467/61. Heading B8H. In a fork lift truck provided with a threesection mast 16, 18, 20, the forks 14 are raised on the inner section 20 by a pair of pull rams 24 and chains 40 at a 3: 1 velocity ratio while the section 20 is held fixed, the section 20, together with the fork 14, is then raised by a push ram 30 and the chains 40 at a 2: 1 velocity ratio and at the same time the intermediate suction 18 is raised by cables 68, 76 at half the rate of the section 20. Each chain 40 passes from an anchorage 38 on the piston-rod 28 of ram 24, round a pulley 42 on the cylinder of ram 30, a pulley 36 on piston-rod 28, a pulley 44 on the piston-rod 32 of ram 30, pulleys 46, 48, 50 in section 20 to a lug 52 on the fork 14. The section 20 is locked to the section 18 by a latch, Figs. 11-14 (not shown) which is released when the forks 14 reach the top of the section 20 by a finger on the forks which at the same time open a sequence valve to allow pressure fluid to pass to the ram 30. Extension of the ram 30 then raises the section 20 by means of the chains 40. At the same time the section 18 is raised at half the speed of the section 20 by a cable 68 which is secured at 70 to the section 20 and passes round a pulley 72 at the bottom of section 18 to an anchorage 74 on the fixed section 16. A cable 76, secured to the sections 20, 16 at 78, 82 respectively and passing round a pulley 80 on the section 18, ensures that when the section 20 is lowered, the section 18 will be pulled down at half the speed of the section 20. The effective areas of the pistons of rams 24, 30 are chosen to maintain a constant upward speed of the fork as the ram 30 takes over from the rams 24. The mast section 16 comprises braced channel members 16<SP>1</SP>, 16<SP>11</SP>, Fig. 20, provided at their upper ends with rollers 186, 186<SP>1</SP>, the section 18 comprises I-members 18<SP>1</SP>, 18<SP>11</SP> and is provided with upper and lower rollers 196, 196<SP>1</SP> and 188, 188<SP>1</SP> respectively, and the section 20 comprises I-members 20<SP>1</SP>, 20<SP>11</SP> provided with at their lower ends with rollers 198, 198<SP>1</SP>.

Abstract: 918,879. Photo-electric high-resolution spectroscopy. IMPERIAL CHEMICAL INDUSTRIES OF AUSTRALIA & NEW ZEALAND Ltd. Dec. 19, 1960, No. 43657/60. Class 40 (3). The absorbing medium in the invention of Specification 918,783 is replaced by an atomic beam to provide sharper absorption bands. Atomic beams are obtained from an oven 11, collimated by slits 15, 16 and finally condensed by a liquid nitrogen cooled surface 18. Windows 19, 20, 21 permit transmission of light. With atomic beams the invention is not applicable to the measurement of partial pressures, but may be used for process control by monitoring the concentration of reaction intermediates or products. Vibrations are investigated by allowing light from a fluorescing atomic beam to fall on a vibrating member. The light refracted, reflected or transmitted thereby is analysed and changes in profile give an indication of the velocity distribution of the refracting, reflecting or scattering centres. Specification 763,556 also is referred to.

The engine speed responsive force applied to the spool 22a of the control valve 20a comprises the pressure drop across a throttle 290 in the delivery 292 of the engine driven pump 106a. The pressure drop is applied across a piston 280 integral with the valve spool 22a to move the latter left against the bias of a spring 102a which reacts against a plunger 314 positioned in accordance with accelerator pedal position. The liquid pressure supplied from the control valve 20a to the displacement adjusting servo 34a is additionally fed through a duct 130a to a chamber 134a between the valve spool 22a and the plunger 314 and opposes the engine speed responsive force on the valve spool. The servo 34a actuates a pilot valve 282 of a follow-up servo motor 284 which effect adjustment of the displacement of the pump 14a. A brake valve 338 is provided between and normally connects the control valve 20a to the reversing valve 32a. On depression of a brake pedal 236a the spool 326 of the brake valve 338 is moved right to connect the servo 34a to drain and permit springs 334 to reduce the displacement of the pump 14a to zero prior to actuation of the vehicle brakes.
