Filed: 1927-01-24
Abstract: 281,502. Bergere, F. Jan. 24, 1927. Moulding confectionery and balls; endless-chain machines; extrusion machines. - Chocolate articles are formed under pressure by forcing semi-plastic chocolate into a normally unvented mould 30, and relieving pressures above a predetermined maximum in said mould to permit complete filling under pressure. A plurality of moulds 30, Figs. 1 and 4, are adapted to be moved intermittently on an endless chain 10, and when beneath the filling nozzles 26 are adapted to be lifted against the same. The lifting means consists of elevators 32 and guide rods 34, which are slidable on an elevator bar 37, and springs 38, surrounding the rods 34, serve to raise the moulds when the bar 37 is lifted by rods 39. Feed cylinders 18 are connected by passages with a chocolate reservoir 14, and such cylinders have pistons 20 actuated by a bar 22 through rods 24. The moulds 30 comprise a base portion 40 having core members 42 on its upper face, and a corresponding upper portion 50 having a rim 51, which is slotted to receive clamp studs 45 pivoted on the base member. Springs 47 mounted on the ends of the studs 45 bear on discs 48 engaging brackets 52 on the rim 51 of the upper member. Pins 49 on the lower member engage positioning apertures on the other member. The recessed members 54 on the upper mould portion 50 have openings 55, which may be reinforced by rings 56 forming seats for the nozzles 26 during filling. The rings 56 also serve tc support a bar 60, having clamping means 61, 62, and such device provides for the correct positioning of tubes 64 for supporting handles 70 for the chocolate cups. During moulding, the pressure within the mould rises as the chocolate enters and causes between the mould members a slight opening, which releases the pressure and allows completion of the filling operation. The mechanism for depressing the pistons 20 is arranged to operate only when the moulds 30 have been pressed upward against the nozzles. The chocolate article consists of a cup 73, Fig. 8, having a boss 75, and a handle 70 of wood &c. The cup may be employed for containing ice cream &c. 77, and is adapted to have a highly polished surface.

Title: Improvements in or relating to clamping mechanism for printing plates
IPC: B41F27/10
Filed: 1933-10-23
Abstract: 427,382. Printing-surfaces. HART, H., 9, Kingsway, London.-(Wood Newspaper Machinery Corporation; 501, 5th Avenue, New York, U.S.A.) Oct. 23, 1933, No. 2372/35. Divided out of 427,336. [Class 100 (ii)] A device for clamping plates to a printing- plate cylinder comprises clamps held in active position by springs, an operating rod, and co-operating cam surfaces on the rod and connected to the clamps so that angular movement of the rod releases the clamps against the action of the spring. The device is adapted for use with plates which have been provided with registering notches 69, Fig. 5, by the apparatus described in Specification 427,336, and comprises pins 71 adapted to co-operate with the notches. The operating rod 157, Fig. 2, is squared at one end and is provided at the other end with a cam 158 co-operating with a cam 159 on a slidable rod 160. The rod 160 is pivoted to an arm 161, to which is fastened a gear 164. The gear 164 meshes with racks 165, 166 on rods 167, 168 which are adapted to rock clamps 169, 170, for the printing-plate P, against the action of springs 171, 172. A rod 174 pivoted to the arm 161 operates a third clamp 175, between which and a spring-pressed clamp 176 the inner printing plate P' is gripped. Rotation of the rod 157 thus releases or grips both the plates P, P<1>. In a modification, rotation of the rods 183, 189, Fig. 5, acts directly by means of cams 184 on a spring-urged outer clamp 180 and three inner clamps 181, which are arranged in staggered relationship and of which the centre one is adapted to grip the inner plate P<1>. The cams are arranged to force the clamp 180 to the left, the centre clamp 181 to the left also, and the two other clamps 181 to the right, all against the action of springs 182. The spindle 183 is squared at the end and geared to the spindles 189 for simultaneous working. The cams 184 have small flat surfaces at their tops so that they will hold themselves in the unclamped position. A slot on one of the gears accommodates a fixed pin and prevents the cam-rods from being turned too far.

Title: Purification of acrylonitrile
Inventor: HADLEY DAVID JAMES
Filed: 1958-01-25
Abstract: Acrylonitrile containing dissolved acrolein and water, e.g. as obtained in catalytic vapour phase reaction between acrolein, ammonia and oxygen, is purified by a process comprising fractionally distilling the impure acrylonitrile to separate an overhead fraction containing substantially all of the acrolein and water together with a proportion of the acrylonitrile, and a bottom fraction of pure dry acrylonitrile, mixing the overhead fraction with water to form an aqueous phase and an acrylonitrile phase, and returning the acrylonitrile phase to the fractional distillation.  The impure acrylonitrile may contain up to about 3% of water and between 5 and 10% of acrolein but proportions of between 1 and 2% water and 0.3 to 0.5% acrolein are preferred, the latter being obtained by first fractionally distilling a wet acrylonitrile of 5 to 10% or more acrolein content and taking off a fraction containing the acrolein as an azeotrope with water and a small proportion of acrylonitrile, while removing wet acrylonitrile of 0.3 to 0.5% acrolein content as the base product.  The amount of water added to the overhead fraction is suitably between 1/2 and 4 times the weight of feed to the still and the resultant upper acrylonitrile phase is returned to the fractionating column by combination with the feed to the column or by introduction at the top of the column.  The resultant lower aqueous phase may be led off as the main outlet for acrolein in the recovery process when the starting material contains a substantial amount, e.g. 5 to 10%, of acrolein, but when only a 0.3 to 0.5% proportion of acrolein is present, the aqueous phase is recycled to a previous stage in the recovery process, e.g. the stage at which the aqueous solution of acrylonitrile, obtained by scrubbing the catalytic oxidation product with water, is concentrated.
