Title: Improvements in cleaning devices for tubes
IPC: F28G3/02
Filed: 1941-03-14
Abstract: 544,240. Cleaning tubes. NORTON GRINDING WHEEL CO., Ltd. March 14, 1941, No. 3534. Convention date, March 2, 1940. [Class 99 (ii)] [Also in Group XXIII) A device for cleaning the interior of the tubes of boilers, stills &c. comprises an abrasive body of bonded silicon carbide grains having embedded therein one or more elongated pieces of metal so that, as the abrasive is worn away, one or more metal islands will be left in the abrading-surface. Fig. 3 shows a rotary tool for attachment to the shaft of an air motor, comprising a. pair of abrasive bodies 41 pivoted at 35 to a head 24, which consists of a longitudinally divided member screwed into a socket 20 attached to the motor shaft, so that as the tool rotates, the bodies are pressed outwards against the inner wall of the tube by centrifugal force. The metal insert is in the form of hair-pin wires 46 extending around the pivots 35 and terminating near the abrading- surface. In a modification a single abrasive member of bullet shape is used, wires being embedded transversely in triangular form. To make the abrasive, coarse silicon-carbon grit is coated with furfural, and mixed with phenol formaldehyde, fine abrasive, quicklime, and creosote oil; but rubber, shellac or other bonding-materials may be used instead of the formaldehyde.

Title: Improvements in automatic weighing machines
Inventor: SIMON WILLIAM GEORGE
IPC: G01G13/00
Filed: 1943-03-08
Abstract: 565,729. Automatic-feed weighers. SIMON, W. G., and SIMON, F. R. March 8, 1943, No. 3698. [Class 143] In an automatic weighing- machine the material is fed to the weigh pan by a tray which is reciprocated at a rate in the region of 2,000 to 3,000 complete reciprocations per minute and with an amplitude in the order of 1/32nd of an inch, the object being to ensure that irrespective of the physical nature of the material the amount in suspension when the feed is cut off is substantially constant or varies only within small limits. The material passes through an inlet 1 on to a feed tray 2 reciprocated by an electro-mechanical vibrator 4. The front of the tray is supported by a spring 7 and extends into a housing 18 surmounting an enclosure 17 for the upper part of the weigh pan 8. Flexible dust-proof seals 19 are provided between the tray and housing 18 and feed inlet 1. The knife-edges of the scale beam 9 are situated outside the housings to avoid the deleterious effect of dust. The discharge gate 23 of the weigh pan is connected by a link 26 to a quadrant 27 and is locked in the closed position by a catch 30, 31, Fig. 4, engaging a notch 29 in the quadrant. The material entering the weigh pan causes it to descend followed by a weighted lever 34, Fig. 3, which ultimately 'descends upon a roller 35 at the end of an arm 39 projecting from a shaft 40. When the requisite weight is made up, a peg 37 on the lever 34 rides down the roller 35 and rocks the shaft 40 together with arms 41, 42. The arm 41 breaks the circuit of the vibrator 4 and stops the feed. A peg 43 on the weigh pan co-operates with the arm 42 to ensure movement of the contact arm 41. The end of the descending lever 34 now strikes the catch 30, 31, Fig. 4, and .disengages it from the quadrant 27, allowing the discharge gate 23 to open and discharge the weighed material. The quadrant on liberation, slides a bolt 47 into the path of the arm 42 and delays the return of the contact arm 41 until the quadrant and discharge gate have returned, thus preventing premature restarting of the feed.

Title: An improved device for pouring liquids from one vessel into another
IPC: B65D47/40
Filed: 1927-02-09
Abstract: 282,571. Levy, L. Feb. 9, 1927. Drip retaining and separating devices.-Drips of liquid caught in a gutter arranged around the pouring lip or spout of a vessel are continuously returned to the interior of the vessel by capillary action assisted in some cases by gravity. The construction shown in Fig. 7, Which makes use of both capillarity and gravity comprises an annular stopper A of cork &c., adapted to fit the neck of a bottle or the like, a tubular part B, preferably of metal, formed with a lip a and a lower internal rim b, and a second parttubular portion C having a spout c and slotted along the side opposite to the spout at d, Fig. 4; the part C is formed with two pressed-in wing portions e<1>, e<2>. To facilitate assembly a punchmark f is made in parts B and C. The operation is as follows : Liquid poured from the vessel flows out by the spout c; the rim b prevents any liquid entering the annular space between parts B, C. Any part of the liquid meeting the wings e<1>, e<2>, is deflected towards the spout c. When pouring ceases drops formed beneath the spout c descend along the outside of the part C until they reach the annular space, whereupon surface tension causes the liquid to spread ; it emerges from the annular space by way of the slot d and passes over the rim b to return to the vessel. The device may be provided with a suitable closure cap such as D, Fig. 14, which may be formed with a plug q adapted to fit within the part C, and may be permanently associated with the vessel. Fig. 17 shows a telescopic form of the device in the extended position, for pouring. Drops formed at c collect in the gutter G and can re-enter the vessel via the point C<1>2 when the pouring member is lowered. In Fig. 18, a hooked rod K provided' on the screwed closure cap engages under a pin T to withdraw the slidable pourer part for use. Fig. 25 shows a form in which the slidable pourer C is integral with the closure, the rim of which has a bayonet connection with the outer member. Liquid is poured through an aperture c<3> in the part C, the aperture being completely covered when the pourer is lowered.

A p.c.m. channel has spaced along it a number of repeaters, each of which reshapes but does not re-time the signal at its input. The last repeater feeds a regenerator which retimes the signal, so removing cumulative jitter introduced by the train of repeaters. Each repeater, Fig. 3 (not shown) generates a unipolar signal b, Fig. 2, which is similar to c on arrival at the next repeater. In this repeater an equilizer shapes the received signal to present signal c to a bistable which changes state when c exceeds certain positive and negative thresholds and generates a unipolar signal b for transmission to the next repeater.

Abstract: 882,519. Rotary pumps or motors. SIMPSON, G. G. May 2, 1958 [Feb. 7, 1957], No. 4198/57. Class 110 (2). A pump or motor of the axially-sliding vanetype has a rotor 1 with tapered sides and containing vanes 13, in slots, the vanes having parallel sides 16 which coact with the parallel sides 21 of a stator built up of parts 17, 18, 19, 20. The stator may be tilted to vary the displacements of the chambers between pairs of vanes. The inner and outer edges of the vanes are curved and slidable on the inner curved edges of the parts 19, 20 and on hub sections 7. The whole is mounted within a housing 4, 5 carrying bearings 3 which support the rotor shaft 2. The rotor is keyed to the shaft 2 and clamped between part-spherical washers 7 by a nut 8. The stator may be tilted by means of two trunnions 30, 31 which may be actuated by e.g. a worm and worm-wheel. The trunnion 31 contains the delivery branch 39 of the pump. Inlet ports 34, 35 lead from a suction branch 36 and delivery ports 37, 38 lead to the branch 39. In a modified arrangement, Figs. 7, 8, 9 (not shown), for a motor, liquid under pressure is fed through both trunnions and the tilting means for the stator is positioned away from the trunnions. Two rotors may be secured on the shaft-one on each side of a stator so that end thrust balancing is secured.

Abstract: Composite wood board is prepared by drying wood plates to a moisture content of 1-12% (preferably 4-8%), dispersing thereon an aqueous thermosetting resin mixture, again drying to a moisture content of 4-8% (preferably below 6%), and then compacting the mass by heat and pressure.  The resin, which may be applied by spraying, is in sufficient amount to provide 3-15% (preferably 5-8%) resin solids relative to the weight of the flakes.  The resin, e.g. urea, melamine, epoxy, urethane, or resorcinol resin, may contain up to 80% of lignin, preferably in the form of a sodium salt, or up to 30% of sucrose, fructose, or dextrose. Drying of the resin-coated flakes may be effected, as a separate step or simultaneously with the application of the resin, by means of a stream of dry gas or gas at a temperature of 100-400 DEG F., or by subjecting the flakes to a vacuum.  After drying, the flakes are matted, pressed to produce a body of the desired thickness, and finally heated to cure the resin.
