Title: Improvements in and relating to type bar making machines
IPC: B41B11/52
Filed: 1936-04-28
Abstract: 453,411. Type-bar-making machines. INTERTYPE, Ltd., 215, Farnham Road, Slough, Buckinghamshire. April 28, 1936, No. 12063. Convention date, March 10. [Class 100 (iii)] Moulds; clamping matrices.-Means are provided for limiting the movement of the mould-disc towards the trimming-knives when the mould in use is in the ejecting position, more especially for use in connection with devices of the kind described in Specification 445,909, in which low-quad portions are produced on the slug by means of ribs on the vice-jaws, which enter the mould. When the moulddisc carries several moulds of different sizes, ribs differing in vertical height and projecting to different extents are provided on the vicejaws to suit the different moulds. When. a large mould is in use, and is rotated into ejecting position, a smaller mould may thereby be brought into the casting position, so that the ribs on the vice-jaws would be too large to enter the mould when the mould-disc advances, with consequent damage to the machine. In order to avoid this, banking- blocks are automatically projected into the path of the mould-disc before its second advance with the operative mould in the ejecting position, so as to restrict the movement of the disc. One 34 of the banking- blocks slides on one 6 of the trimming-knives, and two others 40, 41 slide on the other knife 7. The blocks are raised vertically by a sliding rod 38, which is operated by the first elevator when near the top of its upward movement to carry the matrix line to the distributing position. The banking-blocks have inclined surfaces coacting with similar surfaces on the knives, to cause them to be projected as they move upwards. On the descent of the elevator, the rod 38 falls and draws down the blocks.

Patent GB-734756-A (GB)
Title: Improvements in or relating to process and apparatus for crystal separation and purification
IPC: B01D9/00
Filed: 1951-05-24
Abstract: <PICT:0734756/III/1> <PICT:0734756/III/2> Crystals are purified by forcing an elongated compressed mass of impure crystals through a confined zone towards one end where they are melted, removing a portion of the melt and allowing the remainder of the melt to flow back as reflux through the crystal mass, and removing the resultant liquid from the other end of the confined zone.  The crystals may have been derived by cooling a multi-component organic eutectic forming system to crystallize at least one but not all components thereof.  In Fig. 1 a mass of crystals in cylinder 11 is forced by a porous piston 12 towards the lower end where the crystals are melted by a heating coil 19. Part of the melt is taken off by valved line 21, the remainder passing back through the piston to be taken off at 23.  The piston may have flaps which fold back on the return stroke to allow a further crystal mass introduced from conduit 37 to pass through the piston for subsequent compression on the next working stroke. The crystals are derived from a feed entering a freezer 24 by line 34, the resulting slurry being forced by a piston 26 through a filter 33 from which mother liquor is taken off at 36.  Reflux melt from line 23 can be recycled to feed line 34.  In Fig. 5 crystal slurry from freezer 24 is fed by screw 66 to rotary filter 33, the crystals then being fed by screw 63 into cylinder 11.  A solid piston 12 forces the crystals towards the heater 19, part of the resulting melt being withdrawn at 21 and the remainder passing back as reflux and being removed at 62 to line 23.  Instead of being vertical as in Figs. 1 and 5 the purification cylinder may be horizontal.  The Specification lists a large number of eutectic forming mixtures of organic compounds which can be separated by the process of the invention, including mixtures of aliphatic and aromatic hydrocarbons, in particular mixtures of xylenes and cymenes.  A freezing point diagram for mixtures of xylenes is given.  In examples: (1) para-xylene from a para-xylene, meta-xylene mixture is purified; (2) and (3) benzene from a benzene-n. heptane mixture is purified.  The purities of the products were 99 per cent or better.  The results are compared with those obtained with a benzene-n. hexane mixture in (1) a vertical crystallizer with free flowing crystals passing downwards towards a heater and displacing melt upwards; (2) a horizontal crystallizer in which crystals were moved by paddles towards a melting section at one end, displacing liquid to the other end and with a para-xylene, meta-xylene mixture in the same horizontal crystallizer.  Specification 734,754 is referred to.

Title: Improvements in or relating to shredding machines particularly applicable to the manufacture of tobacco
IPC: A24B7/06
Filed: 1920-05-03
Abstract: 142,818. Korbuly, S. March 6, 1918, [Convention date]. Cutting vegetables &c.-A machine for shredding tobacco &c. comprising two parallel shafts 1, 2 each carrying a series of disk cutters 3, 4 the edges of which interact and between which the material is passed, is provided with means for pressing the disks together axially at the cutting- point, the disks being capable of movement along the shaft. Rollers 9, 10 are employed for this purpose, mounted on spring arms 11, 12. The disks are made flat at the edge, giving two cutting-edges, which act between the similar edges of the adjacent disks on the other shaft, and cut shreds equal in width to the thickness of the disks. If greater width is required, a number of disks may be used together to form one cutter disk. Between the disks of each series are distance-pieces 7, 8 slightly less in thickness than the disks, and take-off fingers 14, 15 mounted on rods 16. Guide-plates 17, 18 serve to confine the material and carry steel sharpening-blades 21, 22 which are pressed by springs 23, 24 against the edges of the disks, and receive a longitudinal reciprocating motion from the pivoted arms 27, 28. and the cam-grove 32. The machine is operated by a handle 13, and the casing 35 which opens about a hinge 34 forms, when open, a support for the plate 38 to form a feed-table.. The plate 38 r.ormally closes the hollow space in the bed 37 which contains detachable parts and accessories. The feed-table is completed by a plate 47, and the flap 42 which rests horizontally on a folding bracket 43.

A central heating system includes first and second vessels 1, 2; a line 11 connecting the bottom of vessel 1 to the top of vessel 2; a line 9 connecting the bottom of vessel 2 to the top of vessel 1; a pump 10 in line 9; an electric heater 6 in the upper region of vessel 1; and a heating circuit 12-19. The latter may be in liquid communication with the vessels, as shown, or a closed circuit having a heat exchanger in vessel 1 (Fig. 3, not shown). A thermostat 8 energizes pump 10 whenever the temperature falls below a preset value and thermostat 7 deenergizes the heater when a higher pre-set temperature is exceeded. A mixing valve 13 in the heating circuit is controlled by a room thermostat 20 and a finned-tube convector 17 (Fig. 2, not shown) is provided in the circuit. In the embodiment of Fig. 3, multi-way valves in the pipes connecting the vessels enable the direction of flow to be reversed between the heat-charging and heat-dissipating phases. The systems may use off-peak electricity.

The frame 18 pivots about a vertical axis under the action of the chamber 11<2>, the frame 19 about a horizontal axis under the action of the chamber 113 and the chamber 11<1> acts on a needle holder 16. The Specification as open to inspection under Sect. 91 comprises other forms. In one, the chambers are mounted inside a casing capable of preliminary adjustment in any direction. In a modification, the lever 4 acts on the pistons of the cylinders 9<1>, 9<2> through connecting rods 97<1>, 972, Fig. 8 (Cancelled), and adjustable cranks, and the movements of the lever are braked at 103 or elsewhere. In a receiver device, deformable parallelograms or parallelopipeds are employed, the needle 16 being pivotally carried by a plate 110, Fig. 14 (Cancelled), forming one side of a parallelogram the opposite side of which is fixed to a plate 114 ; the plate 114 forms one side of a parallelogram having a fixed side 113.
