A centrifuge for separating a mixture of two liquids comprises a rotary separating bowl 20 containing a separating chamber 62 communicating via channels 81 with a chamber 42 for the raw liquid mixture and having an outlet 83 for light liquid and an outlet 87 for heavy liquid, annular partition walls 71 72, 73 inclined to the axis of rotation of the bowl subdividing the chamber 62 into a series of radially spaced compartments 75-78 which are interconnected at their top and bottom ends by ducts having baffle means 85-89 which guide liquid flowing through the ducts into the interior of each compartment, the raw liquid mixture entering only one of the compartments, e.g. 76 as shown. Vertical radial walls 63 divide the chamber 62 and hence the compartments 75-78 into a number of sector-shaped chambers which extend in the circumferential direction to not more than 90, preferably not more than 45 as shown. The bowl 20 is supported by a drive shaft 21 in a housing 2 having an upper cover 3 and a bottom closure 4 and adapted to have its interior pressurized or kept under vacuum. In operation, the raw liquid mixture is supplied to the chamber 42 via a tube 8 and passes under the action of centrifugal force via the channels 81 into the separating chamber 62 where it undergoes gradual separation after passage through the various compartments 75-78. The light and heavy liquids collect respectively in chambers 48, 33 from which they are removed by paring members 46, 47 to be discharged through valved conduits 56, 57 respectively.

The drum 3 is normally freely mounted on a shaft 2 and is unwound against a return coil spring 5. Upon overspeed rotation of the drum, pivoted members 6 thereon centrifuge out into engagement with stops 8 secured to the shaft 2 which has one end secured to the pump 9 in an hydraulic circuit 10, whereupon shaft and drum rotation is retarded. During the initial period of operation of the hydraulic system, a pressure relief valve 11 therein is lifted under the action of overpressure in the system to release the pressure so that the initial retardation force applied to the falling workman is reduced. The drum rotation limiter comprises a slotted lever 12 selectively secured to the other end of the shaft 2 and slideably receiving in the slot 13, a pin 15 which also slideably engages a spiral groove 14 in the arrangement casing 1, rotation of the shaft 2 being limited by a stop 16 on the casing 1 engageable by the pin 15 when the latter reaches the inner end of the groove 14.

Abstract: A method of manufacturing an object of cured resin reinforced with glass fibre, comprises manufacturing a chopped glass fibre preform 18 having substantially the same shape as the object of supplying chopped glass fibre 12 to a jet 1 of finely divided liquid, for example water, containing a temporary binder for the glass fibre and directing the jet with its contents of glass fibre and temporary binder towards different parts of the surface of a former 14 until a preform with the required amount of glass fibre has built up on the surface of the former. The bonded preform thus produced is placed in a closable forming cavity of a mould (not shown) for moulding the object, and then resin in uncured condition is injected, sucked or pressed into the forming cavity and thereafter cured. The temporary binder, for example polyvinyl acetate, an alkyd resin, an epoxy resin, a styrene resin or an urethane resin, may be soluble in the uncured resin e.g. a polyester, epoxy or polyurethane used, the temporary binder being maintained in soluble condition when the preform is placed in the forming cavity and the uncured resin is supplied to the mould. The former 14 may be a metallic or PVC mesh, a perforated sheet or a glass fibre fabric impregnated with iron. <IMAGE>
