[Also in Division C3] Haze-free non-ionic surfactants having cloud points up to 100‹ C. are prepared by reacting a primary alcohol of general formula where n is an integer from 6 to 19 or where n is an integer from 3 to 16 and R is a methyl or ethyl group, or mixtures thereof, with ethylene oxide or a mixture of ethylene oxide and propylene oxide at a temperature of 125-180‹ C. in the presence of a catalyst, normally an alkali metal hydroxide, neutralizing said catalyst, recovering the non-ionic surfactant from the crude product, mixing therewith a small but effective amount of an adsorptive clay and recovering therefrom said non-ionic surfactant. The adsorptive clay, which may be acid activated clay or preferably acid activated montmorillonite clay, may be added to the reaction mixture during the neutralization step or alternatively subsequent to the neutralization step but prior to the recovery step.

[Also in Division F2] A spherical plug valve is provided with seats 3, 4, 5, 6 each of which consists of an annular part 9 made of low friction synthetic material such as P.T.F.E. sandwiched between radially inner and outer metal sleeves 7, 8 without being attached to these sleeves. A spherical end part 9 engages the plug, whilst the other end bears through a resilient packing 11, 12, 13, 14 on a part rigid with the valve housing 2. As shown in a valve applied to a hot gas engine (See heading F1S) four seats at 90 degrees are provided. The packings are arranged so that upstream pressures on the seats tend to keep them against the plug, and in the case of the pair of seats 4, 6 the packings are of different diameter so that the resultant force is always in one direction. The sleeves present radial deformation of the part 9 especially in partly closed positions of the valve.

Abstract: 1,238,494. Locking handle. REGENT LOCK CO. Ltd. 24 Nov., 1969 [22 Nov., 1968], No. 55598/68. Heading E2A. A handle 2 and lock 3 combination in a housing 1, adapted to be mounted in a closure member, especially up and over garage doors, which housing defines a cleating in which the handle is received, substantially flush with the housing, when the handle is releasably held in the housing by the lock, the handle 2 being mounted on a pivot pin 9, so that when the lock 3 is released one end of the handle 2 pivots away from the housing 1 about the pivot pin 9 and is capable of operating a latching mechanism 20 connected to the handle at a position remote from the handle and lock combination. The pivoting may occur under the action of gravity or by a spring (25) acting on the projection 27 of the handle 2. The lock 3 may be a barrel lock which on operation of the key 5 moves the plunger 6 against the action of the spring 7 so that the spigot on the plunger 6 moves out of the recess 8 on the handle 2 and after the handle is released it may be moved through the remainder of its 90‹ movement to the position shown in Fig. 4 where the bolt 22 is released from the keeper 24 against the bias of the spring 20.

Abstract: 1,238,836. Recovering antibiotics from fermented whole cultures. ABBOTT LABORATORIES. 17 Jan., 1969 [6 March, 1968], No. 2949/69. Heading C2A. In a process for extracting erythromycin from an aqueous whole culture of Streptomyces erythreus with a water-immiscible solvent, the fermented culture is digested with pancreatinfree protease and/or pancreatin-free lipase before extraction. The proteases may be ficin, bromelin, papain or "Rhozyme" (Registered Trade Mark) P, J, and PF; "Lipase P" (Registered Trade Mark) is also used. Digestion is carried out for about 2-4 hours or longer at about 30-65‹ C. A suitable water-immiscible solvent is amyl acetate. The protease and lipase break down proteins and oils present in the culture which promote formation of troublesome stable emulsions during the solvent extraction; the lipase is also said to destroy a culture-produced esterase that hydrolyses the amyl acetate. The process may also be used in productions of penicillin, tetracyclines, and spectinomycin.

Abstract: 1,251,582. Air cushion vehicles. SOC. DE I. AEROTRAIN. 13 Feb., 1969 [14 Feb., 1968, 23 Oct., 1968], No. 7798/69. Headings B7K and B7L. Air cushion vehicles which are supported by one or more cushions supplied from in front with compressed air, the air escaping via the rear thereby providing the propulsive thrust as well as lift, have their stability ensured by suitably contoured adjustable surfaces positioned in the cushion space and acted upon by the air flowing through the cushion to produce aerodynamic forces and pressure changes opposing pitch and/or roll of the vehicle. In a vehicle which travels on supporting cushions 31a, 32a over an inverted T section track 2a, 2b, 3, the cushion support is provided by a continuous flow of compressed air from compressor 53. Variations in the static pressure of the supporting cushions 31a, 32a are caused by a pair of movable fins 58a, 58b at the front of the vehicle and pivotable about axis 59a and 59b, a pair of resilient distendable wall units 60a, 60b in an intermediate position and surrounding inflatable bodies 61a, 61b and by a pair of pivotable flaps 55a and 55b at the rear of the cushion and controlling the throughput of air. The flaps 55a and 55b are controlled by aerodynamic flaps 75a and 75b outside the cushion and rotatable by the flow of ambient air due to the motion of the vehicle. The guidance cushions 71a and 71b are of a similar construction having movable fins 82a, 82b, resilient wall units 60c and 60d and pivotable flaps 80a and 80b. A pair of flaps 66, pivotable about axes 67, and which are adjusted by springs 68 and by levers 70 operated by jacks 69 are initially closed, but when the desired cushion pressure is reached the flaps pivot about axes 67 to allow air to escape. A further vehicle is described which travels over a flat track, and has no guidance cushions or aerodynamic control of the back flaps.

Abstract: 1,267,106. Settling of finely divided solids materials from suspension in liquids. AMERICAN SUGAR CO. 20 Nov., 1969 [26 Nov., 1968], No. 56910/69. Heading B1D. [Also in Divisions C1 and C6] Finely divided solid materials are separated from suspension in a liquid, such as a carbonation juice from a beet or cane sugar factory, by adding a small proportion (e.g. 0.1 to 30 ppm) of a settling aid, such as polyacrylamide having a molecular weight of 2 to 3 millions, whereby a slurry of solid agglomerates in liquid is obtained, introducing the slurry through a central standpipe 34 into a central position 32 above the bottom of a settling vessel, arresting the upward motion of the influent slurry and displacing it outwards by means of horizontal baffle 40 so that it is dispersed with the liquid in the settling zone 44 from which large agglomerates of solids rapidly settle, removing dense slurry of solids from well 36 through outlet 50, and removing clarified liquid from a peripheral opening 52 at the top of the settling vessel. The clarified liquid is collected in trough 54, and withdrawn through outlet 56. The height of baffle 40 can be adjusted to facilitate variation in the level at which the slurry is introduced into the settling vessel. The depth of the settling zone 44 is partly controlled by rakes 68, attached to rotary disc 72, which move the agglomerates into well 36. The upper boundary of the settling zone may be maintained at level 66 by a pump attached to outlet 50, the pump being controlled by a photo-electric cell 84 sensitized by light from lamp 86 transmitted through clear plastic rod 88. The settling process and apparatus may also be employed in water softening by the lime-soda process.
