Title: Improvements in hydraulically actuated refuse vehicles
IPC: B65F3/28
Filed: 1945-08-22
Abstract: 601,176. Hydraulic machines. BURGESS, A. F. (Wachter, L. W.). Aug. 22, 1945, No. 21459. [Class 69 (ii)] In an hydraulic drive applied to a moving member 20, for packing and discharging refuse, and comprising a piston 31 movable in a cylinder 30 under fluid pressure from a pump 4 via a distributing valve 60, the piston is reversed automatically when the member 20 reaches the gate 15 due to the build-up of pressure, on the left-hand side of the piston 31, which thus actuates a plunger 80 and releases a catch 88 controlling the valves 65 and 66 and causing fluid to flow in the opposite direction. When the piston reaches the end of its stroke the valve assumes a neutral position in which fluid flows through the byepass 67 instead of to the cylinder 30 and the piston is thus stopped having completed a cycle of operations.

Title: Process for the preparation of pure phosphoric acid starting from natural phosphates
IPC: C01B25/22
Filed: 1925-09-02
Abstract: Phosphoric acid free from iron, arsenic and other impurities is prepared from mineral phosphate by treating the di-sodium phosphate, obtained by neutralizing with soda the sulphuric acid solution of the mineral, with an insoluble salt of lead while adding an alkali in order to neutralize the acid liberated from the lead salt, whereby the whole of the phosphoric acid is precipitated as tri-plumbic phosphate, which is then separated, washed and decomposed with an arsenic free acid so as to obtain phosphoric acid and an insoluble salt of lead.  When lead carbonate is used to treat the di-sodium phosphate solution no alkali is necessary, and if sulphuric acid is used to liberate the phosphoric acid in the final step, the lead sulphate which is precipitated may be converted to carbonate for re-use by means of sodium carbonate.  The di-sodium phosphate is employed in concentrated solution so that the sodium salt corresponding to the insoluble lead salt used, for example the carbonate or sulphate, may be readily recovered by evaporation. Mother-liquors resulting in the manufacture of sodium phosphate may be worked up by the process whereby the sodium sulphate present as impurity is recovered.ALSO:By treating the di-sodium phosphate obtained by neutralizing with soda the sulphuric acid solution of mineral phosphate with an insoluble salt of lead while adding an alkali in order to neutralize the acid liberated from the lead salt, the whole of the phosphoric acid is precipitated as tri-plumbic phosphate.

Abstract: 1276492 Conveying cigarettes MOLINS MACHINE CO Ltd 9 May 1969 [10 May 1968] No 22413/68 Heading B8A Cigarettes in channels A and B are conveyed by respective endless belts 6 and 7, so as to merge into a zone defined by pulleys 11 and 25, and from which they are conveyed through channels C and D to packing machines (not shown). The channels A and B may lead from respective variable-volume reservoirs of the kind described in Specification 995,663. The conveyers 6 and 7, may be controlled by respective sensors 13 and 14, bearing on the cigarettes. The proportion of cigarettes fed to the channels C and D may be controlled by a flap 5. The setting of the latter may be controlled by signals transmitted from detectors (3), (3), (Fig. 1, not shown) each of which is responsive (via a cable (4) connected to a movable backwall (1) of the respective reservoir) to the volume of the latter. The flap 5 may be replaced by a baffle which causes the channel A to feed permanently into channel C, and channel B into channel D. The flap 5 may be replaced by a composite flap arrangement (Figs. 5 and 6) in which a centrally positioned flap 38 is in differential gear connection with flaps 37 and 39. The latter are rotated by the action of respective transmission springs 57, 58, and the rotation of gear wheels 61, 61<SP>1</SP>.The latter are driven by gears 63, 63 (one only shown), which are actuated in response to the positions of the reservoir end walls (1). Near the extreme position or each flap 37 or 39, the attachment points of the associated spring 57 or 58 pass over a dead-centre position so that the spring pulls the flap against a stop (61) (Fig. 7, not shown) thus limiting any further movement. In a modification (Fig. 3), the channels C and A are at the same level, as are the channels B and D. The sensors 13 and 14 are replaced by sensors 120, 121, which rest on a feeler arm 126, Thus both sensors 120, 121, have to be raised before the sensor can move upwardly under the force of a spring 129 to cause a speed decrease of the belts 101, 102, in the channels A, B. The respective speeds of the belts 101, 102, may be arranged to be in a fixed ratio, or may be proportioned to the volume of cigarettes in the associated reservoirs. The merging of the cigarettes between the input and output channels is assisted by the action of a belt 111 driven by a belt 115 from sprag clutches on drive pulleys 104, 105, of the belts 101, 102. Thus the drive to belt 111 is from whichever of the belts 101, 102, is running at the faster speed. The action of the belt 111 tends to fluidize the flow of cigarettes in the merger zone. Similarly pulleys 11, 25, tend to fluidize the flow in the construction shown in Fig. 2.
