Title: Packaging methods and machines
IPC: B65B9/207
Filed: 1939-05-16
Abstract: 528,833. Packaging. PAD-Y-WAX CO., Inc. May 16, 1939, No. 14569. Convention date, May 25, 1938. [Class 94 (i)] A method of packaging commodities consists in feeding a web of material to a device which seals it along its margins and along spaced transverse areas to form a succession of sealed envelopes, and in introducing the commodity into each envelope during and prior to the completion of the sealing-operation. A web, preferably of any suitable flexible transparent material that can be sealed by heat, is led from a roll 26, Figs. 1 and 12, beneath a horizontal bar 39 and then upwards and over the surfaces of two conical formers 31 to fold it into a U-shape around a filling duct 37, through which the commodities are delivered into the packets as they are formed. The folded web is drawn downwards by pairs of motor-driven rollers 50, 51 which crimp the edges of the folded web and seal them together, the shafts of the rollers being heated electrically, if required, to assist the sealing. The rollers are joined by transverse members 52, Fig. 8, which seal the web transversely along a narrow zone, and one of the members 52 may be provided with a blade to weaken, perforate, or separate the web between the filled and completed packages. The delivery of an article, or of a predetermined quantity of solids or liquids, is controlled by two valve members 63, 64 which are operated by any suitable means such as a cam on one of the shafts of the rollers 50. 51. A narrow tearing- strip of flexible material or thread 76, to facilitate opening the packages, is inserted between one of the longitudinal folds of each packet by a needle 77 which is reciprocated by a cam. Instead of the formers 31 being fixed cones they may consist of separate elements rotated on their axes. The edges of the web may be doubled, as it passes the bar 39, in order to provide four thicknesses of material at the sides of the packages. A strip of metal foil may be embodied also on the doubled edges to provide more rigid edges for packages which have to be closed again,after the first opening. Two single webs may be used instead of a single web, and in this case the formers 31 may be replaced by means for bringing the two webs into contact with one another. The filling-duct 37 may be inclined or horizontal instead of being vertical, and may be provided with a positively-driven feeding device. Also, the packets may be of double thickness, an inner lining of heat - sealable material and an outer layer which may be of different material glued to the lining.

Abstract: 1461640 Testing gears W FERD KLINGELNBERG SOHNE GmbH 2 April 1974 [26 May 1973] 14622/74 Heading GIG Vibrations produced by two meshing gears are assessed by arranging respective angular accelerometers on the gear shafts, combining the two accelerometer ouput signals to derive the difference therebetween, and applying the difference signal via an amplifier to an optical indicator device or to a device for identifying or marking damaged gear teeth. In the Fig. 1 system, gears 1, 2 are on shafts 3, 4 which are driven and braked respectively. The difference between the outputs of angular accelerometers 8, 9 is formed at 14. The difference signal, after amplification and filtering, is fed to meter 20 and displayed on CRT's 21, 22. Pulses at the rotation frequencies of the shafts are obtained from sensors 11 and trigger the CRT time-bases. Each accelerometer comprises Figs. 2 and 3 a housing 23 for two diametrically opposed Piezo-electric elements 24, 25 inter-connected so that their combined output is independent of disturbing vibrations of the shaft which are not purely angular, and for preamplifier 26. Various modifications are described in which (a) the difference signal is applied to a Schmitt trigger circuit having a threshold which is lowered until a regularly repeating signal peak indicative of a faulty gear tooth exceeds the threshold and actuates a strobe lamp to illuminate the gears, (b) the signal exceeding the threshold is amplified and caused to mark the gear alongside the faulty tooth by spark discharge, or (c) the occurrence of the repeating signal peak causes storage of the corresponding angular position of the shaft or shafts Fig. 5 (not shown) as measured by a shaft angle encoder.

Abstract: 1,106,960. Fluid-pressure servomotor systems. J.M. MITCHELL. April 7, 1965 [April 16, 1964], No.14847/65. Heading G3P. An apparatus for performing a work function in accordance with a pre-recorded input comprises a record 74 mounted for rotation on a platform 32 which is movable in two directions at right angles to each other relative to a fixed base 28. The platform is fixed to two cylinders at right angles to each other which contains pistons fixed to guide rods such as 48 carried by blocks 50 slidable on rods 38 fixed to the base 28. Fluidpressure supplied to one or other ends of the cylinders thus causes movement of the cylinder and platform relative to the guide rods 48. The record 74 has three grooves two of which cooperate with separate feelers 80 to actuate valves which control the two cylinders carried by the platform 32 and a third which co-operates with a feeler 152 to actuate a valve 150 controlling the supply of fluid to opposite ends of a piston-cylinder device 117 whose cylinder is fixed to and extends through the platform 32. In operation, rotation of the record by an electric motor acts through the feelers 80 to move the platform 32 until the valves actuated by the feelers are recentred and actuates the piston of device 117 whose piston rod acts through a rack 124, sprockets and chains 132, 140 and rack 148 to move the seat of the valve 150 until the valve is recentred. The combined movement of the platform 28 and piston rod of device 117 operates a linkage 106, 108, 110, and 104 carrying the tool 270, the linkage 108, 110 being pivoted to and passing through a slot in a member 114 pivoted to the fixed base 28. In a modification, the base 28 is movable in two directions parallel to the directions of movement of the platform, the base being operated in a similar manner to the platform by valves actuated by a feeler which contacts the workpiece. Such an arrangement is used where the tool acts on a moving workpiece e. g. a workpiece on a conveyer belt whereby the base 28 is maintained fixed relative to the workpiece.

Patent GB-600279-A (GB)
Title: Improved process for the production of magnesium carbonate
IPC: C01F5/24
Filed: 1945-06-14
Abstract: A continuous process for the production of magnesium carbonate comprises supplying carbon dioxide to a slurry of calcined dolomitic rock in a series of zones through which the slurry flows, and controlling the growth of magnesium carbonate crystals by additional feeding of fresh slurry to one or more of such zones after the first. The rock, which may be dolomite, magnesian limestone, predazzite, pencatite, brucite, magnesite, or the reaction product of magnesium silicate and calcium oxide, may be suitably burned between 1700 DEG and 2600 DEG  F.  The calcine passes to a hydrator to make a slurry of 6-8 per cent solids, which passes to a carbonator, where carbon dioxide is introduced, for example through a pH-controlled valve, until the pH drops to about 10.5, ensuring the complete carbonation of any calcium hydroxide present.  The temperature rises to about 130 DEG  F. and the resulting slurry is cooled to less than 60 DEG  F. before passing to the first of a series of magnesia carbonators, in each of which the pH is maintained at substantially complete carbonation, i.e. 8.5, by a substantially uniform carbon dioxide feed and additional feeds of magnesian slurry from the calcium carbonator. Four magnesia carbonators may be used, each with a ratio of total volume to feed per hour of 5 : 1 for subsequent froth flotation or a greater number and a larger ratio may be used prior to mechanical separation, e.g. classification.  The carbonation gas may be that from the prior calcination of rock or any fuel gas containing 10 to 40 per cent carbon dioxide.  Nesquehonite, or preferably, Lansfordite crystals are formed in the first magnesia carbonator and grow in the later ones at a rate of about 7 to 10 microns per hour.  Froth flotation may be used to separate the magnesium and calcium carbonate (see Group II), and the former may be calcined to give magnesia for insulation, chemical or refractory purposes. Magnesia taken into solution in the carbonation process may be recycled from the subsequent separation back to the hydrator.ALSO:Froth flotation is used to separate calcium and magnesium carbonates in a slurry thereof prepared by the carbonation of a slurry of calcined dolomitic rock (see Group III).  As collectors may be used organic acids or salts thereof which are anionic in character, for example sodium palmitate, naphthenate or oleate, naphthenic acid or a distillate from pine tar. Sodium naphthenate may be used in amounts of 1.2 pounds per ton of solids.  Magnesium carbonate separates in the froth and calcium carbonate in the tailing.
