Title: Processes for the preparation of sorbic acid and alkyl esters of sorbic acid
IPC: C07C57/10
Filed: 1962-05-09
Abstract: Alkyl esters of sorbic acid are obtained by contacting a gas mixture obtained by the pyrolysis of acetone, containing acetone unconverted and ketene with crotonaldehyde in the presence of an inert liquid dispersing agent and a bivalent metal salt of a fatty acid as a catalyst, removing the volatile companents from the reaction mixture and heating the non-volatile residue with an alkanol, preferably a lower alkanol, or ethanol, in the presence of an esterifying catalyst.  The product may be recovered by fractional distillation subsequent to the removal of volatiles by distillation followed by steam distillation. Sorbic acid is obtained by hydrolysing of the ester. Alternatively the polyester obtained (see Division C3) by the interaction of crotonaldehyde in an inert liquid dispersing agent and a catalyst as above with ketene containing unconverted acetone, may be hydrolysed with alkali and the hydrolysate then acidified with a strong acid, as the polyester may be converted to sorbic acid by thermolysis.  The examples relate to the preparation of ethyl sorbate and its conversion to sorbic acid. Specifications 570,839 and 854,383 are referred to.ALSO:A polyester of b -hydroxy, a , b -dihydrosorbic acid is produced by reacting ketene obtained by pyrolysis of acetone containing both ketene and unconverted acetone, with crotonaldhyde in the presence of an inert liquid dispersing agent and a bivalent metal salt of a fatty acid as catalyst.  The polyester may be converted to the alkyl esters of sorbic acid as the free acid. (see Division C2). Specifications 570,839 and 854,383 are referred to.

As shown, a control system for use with a radiographic apparatus see Specification 1437283 in Divisions G2-G3 and H3-H5, a collimator monitoring unit comprises a detector monitoring circuit 144 which is responsive to selection of a signal-to-image distance, detected by means 100, 122, 124, and to the presence of an image receptor detected by a means 62, to develop a gating signal on a line 166 and a pulse on a line 168, The actual selected image-to-receptor distance, as sensed by a potentiometric means 116, is used as a ratiomultiplier for the radiation aperture, as sensed by a potentiometric means 130. The output of means 130 is compared with the actual image size, as sensed by a potentiometric means 72, at the input to a comparator 18. The difference signal from comparator 180 is fed to a latched flip-flop gate 180, and a gate 204. The gate 188 enabled by the outputs of circuit 144, responds to a comparator output, indicative of a required increase in aperture, to activate a motor drive circuit 200; a one-shot multi-vibrator 196 providing overshoot whereby the comparator output changes to indicate an aperture decrease which is effected through a gate 204 by a motor drive circuit 208. The arrangement operates to maintain the area irradiated at a minimum. Closure of the aperture in response to a comparator output is directly effected through the gate 204. A circuit 148 provides interlock and indication.

Patent GB-459080-A (GB)
Title: A process of treating mixtures containing free acid and acid alkyl esters
IPC: C07C29/06
Filed: 1935-06-27
Abstract: The absorption products of liquid olefines in strong inorganic oxygen containing polybasic acids are treated with such a quantity of water or of aqueous solution of salts, bases or acids that the free inorganic oxygen containing polybasic acids present separate in the form of a comparatively concentrated solution.  On the addition of a further quantity of water or of an aqueous solution, after the removal of the free acids, two layers again result, the lower comprising the alkyl sulphuric ester and the upper a mixture of polymers, paraffins, neutral alkyl sulphate and unconverted olefines. In an example, a benzine obtained by cracking solid paraffin wax in the vapour phase is absorbed in sulphuric acid of 90 per cent concentration.  On adding water, a 63 per cent solution of sulphuric acid is obtained.  The olefines may be produced by cracking mineral oils or vegetable or animal fats. The use of phosphoric acid for the absorption is mentioned.  The Specification as open to inspection under Sect. 91 comprises also the selective extraction of the free acid from any olefine-acid absorption mixture.  The acids include pyrosulphuric and pyrophosphoric acids and benzene and naphthalene sulphonic acids.  The olefines may be derived from natural gas, shale oil, peat or other carboniferous materials.  This subject-matter does not appear in the Specification as accepted.

[Also in Division F2] Upper and lower punches 36, 37 of a rotary press for coating a detergent tablet 10 are twisted in opposite directions during compression to form the coated tablet, the twisting beginning after commencement of compression and being reversed as the punches begin to separate. A tablet press comprises a rotary core press (14), a feed mechanism (18) for core tablets (9) and a coating press (16) therefor, these three units being driven synchronously by a common drive (Figs. 1, 2). The coating press (16) comprises a rotary die head (34) having fifteen peripheral die cavities (35), each seating an upper and lower punch 36, 37 held in guides (34a), (34b) respectively and positioned in the cavities (35) by fixed cams (rails) (61), (62), (63), (64), (66). Each upper punch (36) has a longitudinally toothed section (76) which at the compression station meshes with a rack (74) on a cam follower 71 which is arranged radially of guide (34a) and projecting from a hole (73) therein. A wheel (83) on the projecting end engages a fixed cam 86 which is adjustable in position and slope and pushes the follower into the hole (73) against the action of a spring (78), thereby rotating the upper punch (Figs. 5, 8). When the follower moves off the cam as the press rotates, the upper punch is twisted in the opposite direction, this action being accomplished as the punch begins to move from the upper compression roll 46. A similar action rotates the lower punch in the opposite direction while under compression via roll 45 (Fig. 6). A peripheral twist of <SP>3</SP>/ 16  in. is optimum for obviating shearing of the surface coating. Premature rotation of the punches is obviated by a fixed rail 95 having a flat edge 95 which engages a flat surface 96 of a recess below the head 67 of the punch. The rail 95 does not extend to the compression station of the press, thereby freeing the punches for rotation.

Engine braking in a two-stroke spark-ignition engine is obtained by the provision of means producing a vacuum in the engine cylinder on each outstroke of the piston, and the ignition is short-circuited when the braking means is brought into operation. A lever k, normally held by a spring m in a position in which a cam surface kl thereon actuates a rod h to hold a ball valve g on its seat f, is rotated by a cable n to free the valve g for engine braking, whereby the air in the cylinder is forced out through the passage r and valve g on the piston instroke, and the valve g reseats itself on the piston outstroke so that a high vacuum is produced in the cylinder. A spring o on the lever k contacts the sparking plug terminal to short-circuit the ignition when the lever k is moved to its braking position. The brake valve body d and spark plug b may both be carried by a bush p screwed into the cylinder head ; alternatively the valve body d and spark plug may be screwed separately directly into the cylinder head.
