Title: Improvements in or relating to the Recovery of Essences with the Simultaneous Removal of Sulphur Dioxide from Sulphited Fruit Juices
Inventor: ROYSTON MICHAEL GEORGE
IPC: A23L2/70
Filed: 1967-04-19
Abstract: 1,151,944. Removing sulphur dioxide from sulphited fruit juices. A.P.V. CO. Ltd. 19 April, 1968 [19 April, 1967], No. 18057/67. Heading A2D. A method for the recovery of essences with the simultaneous removal of sulphur dioxide from sulphited fruit juices, comprises evaporating sulphur dioxide, essences and some water vapour from the fruit juice, feeding the evolved vapours or a condensate obtained therefrom into a fractional distillation column, passing the evolved vapours or vapours formed from the condensate at the feed point upwardly through the column, countercurrent to a liquid reflux to which a removing agent for the sulphur dioxide is added, condensing the vapours arriving at the head of the column in the form of a concentrated essence product and returning some of this product to the head of the column to form the liquid flux. The sulphur dioxide which may have been absorbed by the agent, or which may have chemically reacted with the agent, is removed from the bottom of the column. The agent may be an aqueous solution of sodium carbonate, bicarbonate or hydroxide.

Title: Improvements in and relating to refuse-collecting vehicles
Inventor: GIBSON GEORGE THOMSON
IPC: B65F3/04
Filed: 1959-06-01
Abstract: 886,671. Tipping bins into refuse vehicles. GIBSON & SON Ltd., JOHN. June.2, 1960 [June 1, 1959; March 21, 1960], Nos. 18541/59 and 9858/60. Class 78 (4). A dust-bin 25 (Fig. 1) to be tipped into the body of a refuse vehicle is first raised by cables 21 acting on a linkage 15, 16, and is then tipped when a chain or cable 35 becomes taut. The bin is raised in two stages during the first of which a bin-supporting structure 16 turns about a pivot 17 on a bracket 15 while during the second stage the structure 16 and bracket 15 together turn about a pivot 14 on the vehicle. In the form illustrated, trunnions 24 on the bin are received in slotted lugs 22 on a pair of splayed arms 16. The chain 35 passes over a sprocket 36 to a pair of spaced connected bellcranks 32 carried on a shaft 34 joining the arms 16 and connected by a link 31 to an arm 27 which terminates in a hook 28 taking over one of two bars 29 mounted at opposite sides of the bin. The lower end of the arm 27 is normally supported in a notch in the end of a cradle 26 pivoted to the lugs 22 and embracing the bin. Pivoted portions 18 at the ends of the arms 16 carry rollers 19 and are normally splayed outwards to leave the space between the arms clear for a bin. The initial hauling movement on the cables 21, however, draws the portions 18 into alignment with the arms 16 so that the rollers 19 are disposed to engage guides 37 (Fig. 2) on the vehicle during the final tipping movement. The initial raising motion about the pivot 17 continues until the shaft 33 engages the bracket 15 after which the arm 16 and bracket 15 move together about the pivot 14. When the chain 35 becomes taut the consequent movement of the bell-cranks 32 brings a web 32a joining them into contact with the link 31 so that the arm 27 is pulled to tip the bin about its trunnions 24. The invention may be applied to refuse vehicles as described in Specification 680,174.
