Patent GB-1284570-A (GB)
Title: Improvements in or relating to manually operated pumps
Inventor: WILLIS MICHAEL JOHN
IPC: F04B53/12
Filed: 1969-11-05
Abstract: 1284570 Manually-operated pumps AUTOMOTIVE PRODUCTS CO Ltd 1 Oct 1970 [5 Nov 1969] 54229/69 Heading F1A A manually operated pump for supplying fluid at a lower pressure at a relatively large rate and for supplying fluid at a higher pressure at a reduced rate, comprises a body 10 defining a cylinder 11 in which reciprocates a plunger 13 having a hollow stem 12. This stem 12 defines a further cylinder 17 in which a plunger 16, having a stem 15 integral with body 10, reciprocates. By moving bell-crank lever 26 the plungers 13, 16 move relative to the cylinders 11, 17. If plunger 13 moves to the right, fluid is drawn into chambers 19 and 22 from inlet 31, and fluid is dispelled from chambers 21, 23 via passages 37, 39 to outlet 32. If plunger 13 moves to the left, fluid flows from chambers 19, 22 into chambers 21, 23 through non-return valves 46, 47, but since chambers 21, 23 have a smaller crosssection than chambers 19, 22 fluid is still dispelled to outlet 32. At a predetermined pressure, control valve 42 is acted upon via passage 39 to open communication between passage 41 connected to chamber 21 and inlet 31. Thus the larger cylinder and plunger 11, 13 does not pump fluid to outlet 32 and fluid at a higher pressure is supplied at a reduced rate from cylinder 17.

Title: Low Density Products Consisting Mainly of Sugar and Methods and Apparatus for Their Manufacture
IPC: A23L27/30
Filed: 1967-12-07
Abstract: 1,152,610. Dispensible sugar agglomerates. FOREMOST-MCKESSON Inc. 7 Dec., 1967 [14 Dec., 1966], No. 55668/67. Headings A2B and A2E. Low density dry discrete products consisting mainly of sugar (lactose) are prepared by subjecting a liquid concentrate of the sugar containing seed crystal of the sugar to beating in the presence of a whipping agent and with a gas to form a homogenous foam, and then spray drying the foam by atomizing it without shattering impact to make foam particles and dispersing the foam particles in a drying gas. The -resulting discrete particles may be contacted with a warm moist atmosphere rendering the particles sticky and brought in this condition into random contact to form aggregates, from which excess moisture is then removed. The products are free-flowing and readily dispersible in water, have a bulk density of from 80 to 200 grams per litre, and consist of particles that are spheroidal shaped with numerous cells or cavities, the exterior and interior septa walls of the particles being porous and containing fine crystals of the sugar dispersed therein, and are of a size ranging from 30 to 500 microns, with the major part of the material ranging from 80 to 250 microns, in size. The lactose syrup employed may have a concentration of from 35 to 60% solids with the fine crystals present amounting to between 5 and 55% of the total lactose content, the whipping agent may be soya bean protein hydrolysate (amounting to 0.7% of the liquid content of the foam), the gas air, nitrogen or carbon dioxide. The final dried product may contain artificial sweetener e.g. 5.4% calcium cyclamate and 0.45% calcium saccharin. The beating takes place at a pressure within the range of 40 to 120 lbs. per sq. inch and the foam produced is ex- .panded in passing through a restricting orifice from the beating stage into a stacked-disc centrifugal atomizer. The foam particles are discharged from the periphery of the atomizer into currents of hot drying gas within a conical drying chamber. The material may be agglomerated by falling from a conduit 63, Fig. 3B, in a jacketed chamber 62 through an atmosphere of steam introduced through perforations in an annular pipe 71. Warm air circulated through a jacket 65 around the conduit 63, is discharged into the chamber through openings 66 in the lower end of the jacket.

Abstract: 1,140,709. Drying waste solids concentrates. C. GREENFIELD. 14 Dec., 1966 [17 Feb., 1966], No. 56063/66. Heading F4G. [Also in Division B1] In apparatus for drying waste solids concentrates e.g. sewage sludge, the concentrates after comminution in a grinder 2, are mixed with a non-volatile oil or fat in a tank 4 to form a fluid mixture capable of being pumped after the water content of the mixture is removed in a single stage evaporator 9 through which the dehydrated material passes to a centrifugal separator 28 to separate the concentrate from some of the oil which passes to an oil tank 32 for re-use in the tank 4. The stream of concentrate which may contain 30 to 40% by weight of oil passes to a mechanical press 37 from which the oil may be recirculated either into the mixture passing into the centrifugal separator or back to the fluidizing tank 4 and the dried concentrate is delivered to a grinder 41 for subsequent bagging and removal through a line 44 or for use as a fuel in a boiler furnace 11 which generates steam used in the evaporator 9. Water evaporated in the evaporator is passed to a condenser 16.

As the unit heats up, the tubes 58 effect a lowering of the panel 72A which is accommodated by flexings of the side and corner pieces of the raised portion 72 thereby allowing no gas leakage. Lateral expansions of the panel 72A are accommodated by the expansion folds 77, 78.
