Abstract: 1,050,189. Centrifugal pumps. WORTHINGTON CORPORATION. July 15, 1965 [Aug. 31, 1964], No.30025/65. Heading F1C. In a self-priming pumping system having a pump 60 discharging liquid from a well 65 supplied via a conduit 67, accumulation of gas in the well causes the liquid level therein to fall until the pump loses its prime. The consequent reduction in pump discharge results in gravitational closing of a valve 77 for the pump discharge line 75 and opening of an interconnected valve 81 for a return line 79. Thus, liquid from a priming chamber 73 is returned to the well and forces the gas therein up through a conduit 91 and a one-way valve 92 to the chamber 73, thereby priming the pump. Resumption of normal pumping causes the valve 77 to open and the valve 81 to close. In Fig. 4 (not shown), a horizontally disposed centrifugal pump discharges into a conduit which passes through the bottom and extends vertically into the priming chamber to trap a quantity of priming liquid therein, and the liquid return line and gas conduit are connected between the priming chamber and the suction conduit of the pump.

Self-contained portable apparatus for cleaning a beer, milk, or other tank 16 comprises a supply pipe 8 for connection to a mains water supply and leading via an inlet shut off valve 9 to a water storage reservoir 5 having a drain valve 6, a pipe 10 having a filter 13 and leading from the reservoir 5 via a pump 11 for connection by a hose 15 to the tank 16, a pipe 21 containing a valve 21a for returning cleaning water from the tank 16 to the reservoir 5, and electrical control means 3 for automatically effecting the required sequence of washing and rinsing operations. Initially mains water is admitted through the valve 9, the pump 11 (not then operating), and the hose 15 to a rotary sprayer 20 in the tank 16, and drains through the pipe 21 into the reservoir 5, direct entry of water into the latter being prevented by a non- return valve 13a. While the reservoir 5 is filling detergent is added by the operator to the water therein, and when the water level reaches a probe 7 a control circuit is energized to close the valve 9 and start the pump 11 to circulate cleaning liquid through the tank 16 for a desired washing period. The pump 11 is then stopped and the drain valve 6 opened. After draining of the system the valve 9 then opens to initiate a rinsing cycle.

A process for the preparation of a mixture of an aromatic aldehyde with the corresponding aromatic alcohol comprises heating a solution of a primary araliphatic hydroperoxide of the formula wherein Ar represents a monovalent, substituted or unsubstituted aromatic radical in the presence of an organic base and of a chromium compound which is soluble in the solvent employed. In examples, benzyl-, p-methylbenzyl and p-methoxybenzyl hydroperoxides are converted to the corresponding alcohols and aldehydes. Hydroperoxides employed as starting materials are prepared by oxidizing toluene in liquid phase with air having oxygen content reduced to 10% of oxygen at elevated temperature and pressure (1); by oxidizing p-methoxytoluene under similar conditions in the presence of t-butyl perbenzoate and the disodium salt of ethylene diamine tetraacetic acid (2); by oxidizing p-xylene containing sodium pyrophosphate and butyl perbenzoate under similar conditions.

Abstract: 1,232,059. Topping-up devices. ELECTRIC POWER STORAGE Ltd. 8 Oct., 1969 [10 Oct., 1968], No. 48132/68. Heading H1B. An accumulator includes a reservoir for topping-up liquid situated below the top of the plates and means for raising liquid from the reservoir operated automatically by accelerating or tilting the accumulator. The accumulator may be a lead-acid battery. In Fig. 1 the means for raising liquid comprises a series of pools of liquid at different levels joined in series by sloping ramps up which the electrolyte is forced by tilting or accelerating the battery. From the top ramp the liquid flows over inner cover 18 and enters the cell at the centre. In use liquid is continually flowing from the reservoir to the cell and over-flowing back down again but whilst the level gradually drops in the reservoir, the cell remains full. In this arrangement the topping up liquid is electrolyte. In another embodiment (Figs. 3 and 4) the cell and reservoir are arranged side-by-side rather than end to end. In another embodiment, Fig. 5, the means for raising liquid are sloping pipes up which the liquid is forced by acceleration or tilting of the battery. In all these arrangements one reservoir is required for each cell but in the modification shown in Fig. 6 the means for raising liquid discharges it into a single upper reservoir 50 having means for controlled gravity feed of liquid into each cell. In this case, the topping-up liquid is distilled water.

Abstract: 1,232,645. Enzyme preparation of maltose. HAYASHIBARA CO. 28 June, 1968 [30 June, 1967], No. 30998/68. Heading C2C. Maltose is prepared by liquefying a starch slurry by heating or treating with α-amylase, then saccharifying the liquefied starch with #-amylase together with one or more varieties of α-1,6-glucosidase, and isolating maltose from the saccharified solution. The α-amylase is preferably also included with the saccharifying enzymes. The α-1,6-glucosidase may be pullulanase, an enzyme preparation from Aerobacter aerogenes, or an isoarnylase derived from Pseudomonas Sp. (e.g. Ps.amyloderamosa), these enzymes preferably being employed together. The maltose is isolated by conventional procedures (e.g. concentration, decolorizing and crystallization), preferably after removal of impurities with ion exchange resin.
