Phase error is corrected by perforated discs 10, 10a, each having a single perforation and being associated with scanning devices 11, 11a, feeding pulses to comparators 13, 13a. A reference source 15 also feeds pulses to the comparators which provide square wave output voltages whose widths are proportional to the time intervals between the compared pulse trains. The phase error signals are supplied to devices 16, 16a, providing direct voltage signals to the control amplifiers. Delay devices 60, 61, compensate for any difference in the times of transit between the source 15 and the individual drives. As shown, the pulses from source 15 are fed to a bi-stable multivibrator 40 which also receives pulses from the source 11. The output on lead 41 is fed to phase reverser 42 associated with Zener diodes 43 for standardising the pulse height. These pulses are combined with the pulses from the source 15 and applied to R. C. circuit 49 for transmission through lead 50 to the control amplifier.

The sleeve has teeth 7 forming a worm wheel and a worm 8 may be brought into engagement with the wheel by raising a slide 13 by means of a handle 19 on a shaft 20 which has an eccentric portion 21 engaging the slide. A switch 31 is actuated by raising the slide to cut off the normal drive. The worm 8 is secured to a shaft 9 having hand wheels (10). An impulse generator (33) mounted on a cover 23 is sensitive to movement of the teeth 7 to indicate the angular movement of the pump shaft.

Abstract: 1,227,444. Jet pumps. CONDENSEURS DEIAS. May 17, 1968 [May 30, 1967], No.23482/68. Heading F1E. An aspirator, e.g. with steam as the inducing fluid for de-gassing molten metals in a vessel connected to the aspirator, comprises an expansion tube 8 in an aspiration chamber 3, and a convergent divergent diffuser 7 having a divergent section comprising a first portion 7b of axial length 0À2 to 0.3 times the minimum diameter D of the diffuser, a second portion 7c of axial length 8 to 10 times D and either cylindrical or of small divergence of the order of 1 degree, and a third portion 7d. In the embodiment shown, expansion tube 8 has a first section 8a having a divergence angle less than 10 degrees, and a second section 8b having a divergence angle between 20 degrees and 60 degrees. Section 8a is effective when starting aspiration, and section 8b is effective to prevent turbulence when the pressure in chamber 3 is very low. In Fig. 2 (not shown), section 8b of expansion tube 8 is omitted.

Abstract: 1,229,351. Harvesting mushrooms; watering plants. EYE MUSHROOMS Ltd. 1 April, 1970 [1 April, 1969], No. 16981/69. Headings A1E and A1F. [Also in Division B8] Mushrooms are grown horticulturally in legged trays 11 which for harvesting are removed in a stack from a growing enclosure (not shown), fed one at a time by a feeder 1 on to a conveyer 15 carrying the trays past human pickers (not shown) (alongside the conveyer 15) who select, pick, trim and place mushrooms in continuously-weighed baskets, removed from the conveyer 15 and formed into a stack by a stacker 3, and then replaced in the growing enclosure. A tack of five trays 11 is removed by a fork-lift truck from the growing enclosure and delivered on to inwardly-biased pawls 12 of the feeder 1. The feeder 1 (and the stacker 3) comprises a fluid-operated scissor-action lift 13 which as it is raised cams the pawls 12 outwards so allowing the stack to drop on the lift 13 and which as it is lowered (carrying the lowermost tray) allows the pawls 12 to engage under the next tray 11. The lift 13 lowers the lowermost tray 11 on to a pair of conveyer chains 4 which convey it to the picking conveyer 15. Waste trimmed from the mushrooms by the human pickers falls through grills 27 on to endless belts 30 delivering to a further conveyer 37 discharging to a waste bin. A conveyer belt 38 moves baskets loaded with mushrooms on to a gravity feed conveyer 43 leading to a packer. The conveyer chains 4, 15 and 44 are driven in synchronism at a speed which can be adjusted according to crop density. The trays are watered (every day) after picking, either at the downstream end of the picking station 2 or at the beginning of the stacker 3.

Abstract: 1,232,062. Spheroidal oxide catalytic particles. PRODUCTS CHIMIQUES PECHINEY-SAINT-GOBAIN. 2 July, 1968 [4 July, 1967; 1 March, 1968], No. 31577/68. Heading B1E. [Also in Division C1] A process for the preparation of spheroidal particles comprises mixing a first hydrated oxide on a first hydroxide with an aqueous peptised suspension or aqueous sol of an oxide, second hydrated oxide or second hydroxide to produce a concentrated aqueous mixture, and, if necessary, adjusting to pH of the aqueous mixture to cause this mixture to flocculate, kneeding the resulting product in the absence of a medium immiscible with water to transform it to an aqueous suspension of spheroidal particles, washing, if necessary, the spheroidal particles and drying the spheroidal particles to produce the desired product. Suitable compounds include Al 2 O 3 , SiO 2  and MgO although oxides and hydroxides of Ti, V, Th, Fe, Ni, Cr, Mo, W, Zr and the rare-earth metals may also be used. Noble metals may be introduced in the preparation in the form of acid solutions. Secondary components may also be included as fillers, e.g. silicates, clays and zeolites. Conventional steam or other heat treatments may improve structure and texture of the particles. Examples describe preparation and physical properties of products.
