Title: Improvements in the measurement of the mass flow rate of fluids
Inventor: SCANES PERCY
IPC: G01F1/80
Filed: 1960-07-06
Abstract: 952,845. Measuring fluid flow. GEORGE KENT Ltd. Sept. 7, 1961 [July 6, 1960], No. 23711/60. Headings G1N and G1R. A method of measuring mass flow of a fluid consists in deriving one force from the rate of change of momentum in the flow and another from the centrifugal action of a solid mass rotated in the fluid, opposing the two forces and regulating the speed of rotation of the solid mass to balance them, the speed of rotation being proportional to the mass flow of the fluid. The Specification equates algebraic expressions for the two forces (in terms of mass, velocity and density of the fluid and the speed of rotation n of the solid mass) and shows that n is proportional to the mass flow rate within limits of up to Œ20% variation in the fluid density It also states that an optimum density ratio of the solid to the fluid masses is 2. Fig. 1 shows an embodiment in which the momentum of the fluid is changed by a rotor R, capable of free rotation. Masses 8 on pivoted arms 7 are carried inside a hollow shield 2 rotated in a chamber 1a of the fluid by a motor 5. The centrifugal forces due to the masses are applied to a component 13 on the rotor through a linkage 10, 11, 12 and simultaneously a rod 14 moves a core 15 in a differential transformer 16 to control the speed of the motor 5 by way of an amplifier 17. Fig. 2 shows an alternative arrangement wherein the linkage 10, 11 operates on a diaphragm 20 which is subject to the pressure difference across a fixed orifice 0 in the flowing fluid. In both examples mass flow is indicated remotely if required, by means at 18<SP>1</SP>.

Title: Improvements relating to rubber products
IPC: C08J11/26
Filed: 1945-09-17
Abstract: Waste vulcanized natural or synthetic rubber is devulcanized by first reducing to crumb form, treating for from three to seven days or longer with a low-temperature plasticiser, and then hardening by adding lime, magnesia, calcium, strontium or barium hydroxide or zinc carbonate.  Before hardening the crumb may be heated to a temperature not exceeding 150 DEG C. for not longer than 20 minutes.  The plasticiser is preferably a naphthenic acid and is added in the proportion of 10-20 parts by weight to 90-80 parts of crumb.  Rosin oils which form hard rosins with lime or pine tars which form pitch-like products with lime may also be used. The crumb, after absorption of the plasticiser and before or after heating (if heating is resorted to) may be run through the nip of a closed mixing mill which causes the particles to form a lacy mass on the rolls, to which more of the crumb may be added, the rolls of the mill eventually being opened and more treated crumb added to form a continuous sheet, after which the sheet is removed and laid aside to cool.  A weighed quantity is afterwards returned to the mill and re-worked until plastic, whereupon there is worked in a quantity of lime &c. in excess of that required to neutralise the naphthenic acid.

Abstract: 773,844. Agitating the contents of bottles. CERTUS MASCHINENBAU GES. Aug. 19, 1955 [Oct. 12, 1954; June 18, 1955], No. 23897/55. Class 86 The contents of bottles travelling on a conveyer is mixed by turning the bottles end-over-end about a horizontal axis intermediate the ends of each bottle whilst maintaining their forward movement. In the form shown in Fig. 1, a bottle a advancing on a conveyer 1 is seized by the curved jaws 6 of a rotating carrier which has two sector-shaped portions 4 separaated by a space through which the bottle can slide. The jaws 6 turn the bottle so that its bottom engages curved plate 2 which guides it into a stationary helical guide-way 7. At the same time the top of the bottle enters a narrower helical guideway 8. The carrier portions 4, 4 are each secured by a plate 17 to the inside of an anular pulley 9 which is rotated by means of Vee-ropes by a motor 11. As the carrier rotates the bottle slides between the two portions 4 whilst the helical guides cause it to turn end-overend a number of times. Finally an outgoing guide-plate 2 serves to replace the bottle on the conveyer in an upright position. In a modification, Fig. 8 the carriers 4<SP>1</SP> rotate around the helical guides which are made from rods 30 31 and 30<SP>1</SP>, 31<SP>1</SP> bent into helical form and supported near the ends of the machine on pillars 32.
