Filed: 1956-09-21
Abstract: 817,191. Injection moulding machines for plastic cups &c. CROWN MACHINE & TOOL CO. Sept. 21, 1956 [Sept. 23, 1955], No. 29020/56. Class 87(2). An injection moulding machine for, e.g. plastic cups, comprises a platen with a number of separate moulding cavities from which the moulded articles may be ejected in unison, one injection nozzle for each cavity each nozzle having a separate injection unit supplied from a common preplasticizer and each nozzle being arranged on a frame which also supports the platen. The machine has fixed platens 18, 20, 22, 26, 32 and movable cavity and core platens 28, 30 respectively. Hydraulic cylinders 16 on the fixed platen 18 actuate rams 38 connected to injection cylinders 40 with nozzles 42 having reciprocating valves 66 controlling the supply of plastic material from the injection cylinders 40. The cavity platen 28 is movable away from the platen 26, by hydraulic rams 48, to break the injection " pips " from the nozzles 42 which form part of the base of cavities 44 formed in inserts 72 having water channels 74. The core platen 30, actuated by a hydraulic cylinder and ram 34, has, Fig. 4, two core structures 75 each comprising a core element 82 secured to the platen 30 by plates 84, 88. The core element 82 has in insert 92, with water channels 96 connected to a water inlet 100 and outlet 104 in the plate 88, an air piston 140, in a cylinder 142 with grooves 150 in its circumference, connected by studs 156 to an ejector ring 114, and a rod 120, in the insert 92, having at one end a frusto-conical seating 126 forming an air valve and at the other end extending into but not abutting against a boss 138 on the air piston 140. In operation, after the plastic cup has been moulded and its injection " pip " broken, air is admitted to the air cylinder 142, through a connection 146 in the plate 84, causing the piston 140 and hence the ring 114 to move to the left (in relation to Fig. 4) to abut against the rim of the moulded cup to partly free it from the core 82, and at the same time air is admitted through the grooves 150, previously sealed by the piston 140, to the still closed air valve 126, further movement of the piston 140 causes the base of the boss 138 to abut against the rod 120, to move the rod and thus the bottom of the moulded cup and at the same time to emit air from the valve 126 and blow the cup off the core element 82.

Title: Improvements in front-cutting reaper and binder machines
IPC: A01D37/00
Filed: 1961-08-11
Abstract: 985,999. Reaper-binders. L. CASTOLDI. Aug. 11, 1961 [Aug. 12, 1960], No. 29089/61. Heading A1F. A reaper-binder comprises a motorised chassis 10 with a front cutter-bar 15 and a collecting and sheaving device 16 which includes at least one pair of toothed forks 50, 51 performing opposite oscillatory movements to engage the cut crop and compress it into a channel 11 there being binding and ejecting devices located in the channel and set into operation by a predetermined pressure of crop therein and caused to move thereafter in a predetermined phase-relationship with the movement of the forks. The forks are approximately L-shaped in plan and are oscillated by cranks 58, 59 driven continuously, the rear ends of the forks being mounted on swinging levers 54, 55. The crop builds up against a gate 63 which holds it. As the quantity increases a pivoted finger 71 is forced back and releases a bolt 75 which normally holds one end of a bell-crank lever 78 so that a roller 83 on its other end is out of engagement with a tooth 85 inside a continuously rotating hollow member 84. Engagement of the roller 83 and tooth 85 rotates a shaft 88, through links 80, 86, 87, to carry the knotting needle 65 across the channel where it engages a knotting device 66, of conventional construction. The needle, in its movement, contacts a bell-crank 105 linked to a latch 110, so that the gate 63 is opened after a certain travel of the needle; simultaneously an ejecting arm 94, which moves continously through a closed trajectory F, pushes the bound sheaf rearwardly out of the machine. Springs 73, 100 then return all the parts to their original positions. The various continuously-moving parts are driven by the motor 13 of the machine which also drives the cutter-bar through a crank 22 and bellcrank 45, 46.

Abstract: 364,053. Hatching - appliances. BRIDGE, J. W., Coptrod Hatcheries, Lower Healey, Rochdale. Sept. 29, 1930, No. 29123. [Class 5 (ii).] Eggs are hatched in approximately horizontal trays having a rotary movement about a vertical axis, the trays being of open mesh in the shape of a sector of a circle and being arranged on supports radiating from a central shaft, so that carrying round of the air in the incubator is obviated as much as possible and any movement of the air is substantially vertical. A casing A having double walls the space between which is packed with insulating material, has a central vertical shaft B which is rotated by worm gearing operated by a motor C. Spiders D on the shaft support uprights d<1> which carry angle-bars d2 radiating from the shaft and joined by strips d<3>. The sector-shaped egg trays, which have mesh bottoms, are provided with wires to support the eggs, the said wires being so shaped as to lie on the surfaces of cylinders coaxial with the central shaft of the incubator, and to have a component curvature vertically which decreases progressively towards the central shaft. The eggs are spaced apart so that on reversal of the direction of rotation of the shaft B, the eggs will roll over : the shaft B may be automatically reversed. Alternatively, a rod c, pivotally attached to the apex of each tray and lying beneath the said wires, may project through a slot in the edge of the tray, for turning the eggs. The trays slope slightly downwardly towards the central shaft and are separated from one another by mesh walls, Fig. 5. In a modification, Fig. 6, the mesh walls form part of the trays themselves. One side of the wall of the external casing, which may be octagonal, is in the form of a door for removal of the trays. Oxygen, supplied from a cylinder f<1> is heated by a thermostatically controlled element f mounted over a water tray f<4> in a chamber F connected by a perforated tube f<2> to the main compartment.

Abstract: 489,640. Gas-producers. KOSTER, W. Oct. 27, 1936, No. 29192. Void. Convention date, Dec. 28, 1935. [Class 55 (i)] In a downdraught gasproducer provided with an axially adjustable air inlet pipe 2 so as to vary the position of the combustion zone 6 relatively to the grate 3 to suit the requirements of different fuels, the reducing zone 7 is constructed of greater crosssectional area than that of the combustion zone to reduce the velocity of the combustion gases. The lower part of the producer preferably takes the form of a frustum of a cone and is charged with charcoal or coke to remove tar and soot in the gases generated. The base of the inlet pipe 2 is provided with a cowl 8 which enables a well 9 to be formed between the base of the pipe and the combustion zone. Volatile products from the superincumbent fuel flow through apertures 10 in the cowl for combustion in the fuel bed of the producer. The producer may be started by connecting the gas withdrawal pipe 4 to suction and supplying charcoal and cotton-wool soaked in petrol to the fuel bed through the air inlet pipe. The charge above the charcoal or coke may comprise bituminous fuel such as brown coal briquettes.

Abstract: 1,101,662. Centrifugal-casting machines. J.E. ORME. 24 July, 1964 [24 July, 1963], No. 29321/63. Heading B3F. [Also in Division B5] Articles of P.V.C. or metal are centrifugally cast in an oven using a series of moulds MD, each of which rotates about its own axis XR and is carried radially from a horizontal heatinsulated shaft BS which itself rotates about its own axis. The shaft is mounted at one end in bearings 31, 32 and is rotated at its other end by means of a gear 17 connected to the shaft via a driving bush 13, a yoke 12 and arms 23. The arms 23 carry a cross-piece 21, on which are mounted a bevel gear 40 and a sprocket 42, connected by chain T to similar sprockets mounted on rods 2 carrying the moulds MD. The gear 40 meshes with a gear 41 carried by a shaft 25 which is either stationary or rotated at a different speed from the bush 13 by means of clutch 18 connected to drive gear 17, or by means of an independently driven pulley wheel 26. As the yoke is rotated relative to the shaft 25 it can be seen that the arm 21, as well as rotating with the yoke, will be caused to rotate about its own axis, thus causing rotation of the moulds about their axis through the means of chain T and rods 2.

Filed: 1955-10-19
Abstract: Monohydric phenols and aliphatic ketones are prepared by decomposing a hydroperoxide of formula <FORM:0802524/IV (b)/1> wherein R1 and R2 are alkyl groups and Ar is an aryl or alkaryl group, in a process which comprises mixing acetone and sulphuric acid in the presence of water and adding the hydroperoxide to the mixture to form a homogeneous reaction medium, the concentration of sulphuric acid in the medium being not more than 10 per cent by weight and the concentration of water being insufficient to render the medium heterogeneous.  The process minimizes the formation of mesityl oxide. The medium to which the hydroperoxide is added is preferably prepared by mixing acetone and sulphuric acid in the presence of about 2 to 8 per cent of water.  The preferred concentration of sulphuric acid is from about 0.05 to about 0.5 per cent by weight.  Specified hydroperoxides are a :a -dimethylbenzyl, a :a -dimethyl-p-methyl- or -ethyl- or isopropyl-benzyl, a :a -ethylmethylbenzyl and a :a -dimethylnaphthylmethyl hydroperoxides.  Hydroperoxides containing anthracene and phenanthrene as aromatic nuclei and also those substituted in the aryl nucleus by methyl, ethyl, propyl and butyl groups may be employed in the process.  The formation of mesityl oxide in a reaction medium prepared according to the process of the invention by mixing acetone and sulphuric acid in the presence of water and in a medium wherein no water is present, is compared.  In an example, isopropylbenzene hydroperoxide was decomposed continuously by the process of the invention to yield mainly phenol and acetone.
