Title: Improvements in apparatus for automatically filling boxes or bottles with substances in either a plastic, granular, powdered, fluid or tablet form
IPC: B65B1/36
Filed: 1921-01-18
Abstract: 183,154. Barton, F. H. Jan. 18, 1921. Packing and filling plastic and pulverulent materials into boxes; packeting tablets and pills in receptacles.-In a machine for filling bottles and boxes and of the kind in which the receptacles are fed on to a rotating table and are raised up to revolving filling nozzles or shoots above by plungers carried by the table, the receptacle-feeding-mechanism is arranged to work in conjunction with interchangeable mechanism adapted to deal with materials in plastic, powdered or granular, tablet or pill, or fluid form and to deliver the required quantity of material. The receptacle-feeding mechanism comprises a spindle B, Fig. 1, mounted on a fixed table A and carrying a rotating table C, provided with equally-distributed openings in which plungers D are located, a rotary feed-wheel E formed in its periphery with gaps which guide the boxes or bottles on to the tables C and locate them above the plungers D, and a cam F on the table A for raising the plungers. When a plastic substance is to be fed into boxes, the substance passes from a pug mill H through a single opening G<1> in a fixed table G into the box below, the cam F raising the plunger D on which the box rests until it touches a rotating cut-off plate J located beneath the fixed plate G and provided with openings, corresponding to the plungers, the plate controlling the supply of the material to the boxes. A rotary hopper replaces the parts G, H. J when powdered substances are to be packed. This hopper has an outlet above each plunger and in each outlet is a worm. When the cam F raises the box up to the outlet, the worm is rotated to force a predetermined quantity of powder into the box by a fixed segment on the machine engaging a toothed wheel on the shaft of the worm. When the machine is to be used for filling bottles with liquid, a rotating tank T, Fig. 7, is fixed to the spindle B. The lower parts of the stems U<1> of valve U, located in the tank directly above the plungers D, are made hollow and have flanges U<2> into which the bottle K<1> are thrust to raise the valves and allow the liquid to flow through the hollow stems into the bottles. Springs U<4> return the valves to their seats. When the machine is arranged for packing tablets or pills, the tablets slide from a fixed hopper V, Fig. 5, on to a. rotating table W and axe swept by brushes X into perforations W<1> each of which receives one tablet. In one half of a fixed plate Y beneath the table W are openings Y<1> through which the tablets can fall into funnels Z<2> fixed to a rotating table Z and leading into the boxes. The openings Y<1> may be closed by slides Y<3> to regulate the number of tablets delivered into each box.

Title: Flexible tubing and the manufacture thereof
IPC: B29C48/15
Filed: 1966-01-19
Abstract: 1,139,961. Flexible tubing. GENERAL CABLE CORP. 19 Jan., 1966 [1 Feb., 1965], No. 2469/66. Heading F2P. [Also in Division H1] A flexible duct comprising a metallic strip 14, folded into tubular form with no internal support and with its edges 18, 18 free for relative movement, is prevented from collapsing inwardly when a jacket 36 of plastics material, e.g. polyethylene, is extruded over it, allowed to cool and contract, by initially coating the strip 14 with a thin layer 24 of highly adhesive polyethylene containing reactive carboxyl groups which forms a chemical bond with the metal, the relatively thicker outer jacket 36 being firmly bonded to the inner layer 24 so as to prevent relative movement between the outer jacket 36 and the folded strip 14 and between the strip edges 18, 18. In this way the plastics material is unable to slip relative to the metallic strip 14 shrinkage being able to take place only by radial contraction i.e. by reduction of thickness. As shown, a transversely corrugated aluminium strip 22, which is coated on one, 24, and preferably the other side, 26 with a thin layer, or layers, e.g. of a copolymer of polyethylene and acrylic groups, before it is fed, e.g. from a storage roll, not shown, to pinch rollers 16, is advanced in the direction 12 past a supporting roll 46 and a heater 40 to an extruder 32 to receive the plastics jacket 36, e.g. of polyethylene, the thin layer 24 becoming activated by the hot jacketing material 34 to develop a firm bond with the jacket 36. The thin inner layer 26 is preferably formed to protect the interior surface of the duct, e.g. from corrosion. The duct encloses a loose cable core 10. Alternatively, the duct may be employed to carry a gas. The longitudinal edges of the strip (14) may be slightly spaced, Fig. 3 (not shown), or be arranged in overlapping relationship, Fig. 4 (not shown). As shown, the strip is 0À008 inch, the layers 24, 26 0À001-0À003 inch, and the jacket 0À06-0À08 inch thick.

Title: Apparatus for determining the moisture content of flour, corn, beet pulp, tobacco and other moisture containing substances
IPC: G01N27/22
Filed: 1932-01-29
Abstract: 396,098. Capacitance measurements. LONG, C. H. W., 81, Eastgate Street, Bury St. Edmunds, Suffolk. Jan. 29, 1932, No. 2777. [Class 37.] To determine the moisture content of flour, corn, beet pulp, tobacco or other substance, a measured quantity of the substance is arranged in an electric circuit (a selected electrical, characteristic of which is predetermined) in such a manner as to produce a variation in the said characteristic which may be ascertained from indicating means operatively connected in the circuit and which is substantially proportional to the moisture content of the substance. The apparatus described comprises an oscillator circuit A and a detector circuit B, the detector circuit having a thermionic valve V<2> arranged for anode bend rectification and coupled to the oscillator circuit by an inductance L<2> that is shunted by a condenser C<3>. The condenser C<3> is constructed in the form of a cell and is mounted upon the top of the casing by a plug and socket connection. The condenser is formed by a pair of aluminium plates spaced apart by distance-pieces of insulating material at the sides and at the bottom, and covered on their inner faces with sheets of insulating material such as " Paxolin." The circuit A is caused to oscillate at a desired frequency and by adjustment of the condenser C<4> a maximum reading is obtained from the microammeter M A in the detector circuit. A predetermined weight of the substance to be tested is placed in the cell condenser C<3> and the condenser C<4> again adjusted until a maximum reading is obtained in the microammeter. The difference between the two readings of the condenser C<4> is read off on a graph or chart forming a standard of reference for the particular substance. In a modification the cell condenser may be arranged in the oscillator circuit. The dial of the condenser C<4> may be provided with a frictionally held pointer which is set at zero when the detector circuit is tuned to give a maximum reading in the microammeter with the condenser C<3> empty ; direct readings of the moisture content may thus be obtained when the condenser C<3> is filled. Reference has been directed by the Comptroller to Specification 275,741, [Class 37, Electricity, Measuring &c.].

Filed: 1951-02-06
Abstract: 677,419. Continuous casting. MANNESMANNROHREN-WERKE., HUTTENWERK HUCKINGEN AKT. - GES., and WESTDEUTSCHE MANNESMANNROHREN AKT. - GES. Feb. 6, 1951 [Feb. 7, 1950], No. 2936/51. Class 83 (i). The casting issuing from a continuous casting machine is cooled by contact with grains of a material having a reducing action, a melting- point at most equal to the temperature of the casting, a high heat of fusion and the property of contracting greatly on re-solidification. Examples of suitable materials are water glass and blast furnace slag, to which soda may be added to reduce the melting-point as required. As shown, the casting 2 issuing from a mould 1 passes through a vessel 3 containing granular blastfurnace slag 4 which melts and adheres to the casting as a thin layer 5. After being further cooled by passage through a water-cooled duct 6, the casting is passed through a water spray which causes the slag coating to crack off and collect on a plate 8.

Title: Improvements in or relating to die-casting methods and machines
IPC: B22D17/14
Filed: 1953-02-03
Abstract: 726,551. Casting-machines; moulds. HODLER, F. Feb. 3, 1953 [Feb. 7, 1952; Dec. 29, 1952], No. 3013/53. Class 83 ( 1 ). A process for die-casting comprises injecting molten metal into a die by a plunger in two main phases, the first phase being carried out at a lower speed than the second, evacuating the major part of the air entrapped in the injection cylinder during the first phase and filling the die completely with molten metal during the second phase. Mould parts 62, 63, Fig. 7, are forced together by a hydraulic piston 64 acting through toggle joints 66. The injection cylinder 70 has a plunger 71 connected to a hydraulic piston 72 moving in a cylinder 73 forming part of the machine frame. The pistons 64, 72 are supplied with liquid from a pump and motor 78, 77. The liquid is delivered to a pipe 80 and a control valve 81 which is operated by a hand lever 86. On moving the control from positions 1-4 switch contacts 112a are temporarily closed, causing a valve 89 to open and a similar valve 98 to close. These valves are operated by auxiliary pistons fed with compressed air from valves 93 which are electromagnetically controlled. Valves 82, 83 remain closed until position 3 is reached, when valve 82 opens to admit fluid to the piston 64 which clamps the mould parts 62, 63 together. When the control lever reaches position 4 valves 82, 83 are both open and a contact-piece 110 engages a contact 112b. Liquid enters pipe 88 and passes through valve 89 and also around a smaller by-pass 94 joining again prior to passing through adjusting valve 96 to cause a slow injection movement of the pistons 71, 72. A stop 120 on the connecting-rod between these pistons strikes a switch 118 which closes the valve 89 and opens a valve 107 to start suction of air out of the mould through the pipe 106. The by-pass 94 allows a small flow of fluid to the piston 72 which thus moves the injection piston 71 slowly forward. As soon as the pressure inside the mould cavity has been reduced to the desired point a manometer 108 connected therewith allows current to pass through a circuit 114, this circuit is, however, additionally controlled by a switch 116 in the form of a detecting device which is closed only when the level of casting metal in the mould reaches it. Cement flowing through circuit 114 operates a relay 115 and, through further switches and relays, opens the valve 98 to start the stage of rapid injection of molten metal into the mould. As soon as the metal reaches the level of a piston valve 129, Fig. 8, extending into the mould cavity, this is moved and through lever connections closes the.valve 125 through which air has been withdrawn and prevents any metal particles passing into the suction line 106. The machine is subsequently opened by returning the control lever 86 to position 1 when, after removing the casting, a fresh operation may begin. Modifications are described including a simplified mechanical operating device for obtaining the two injection movements, with omission of the suction pump.
