Title: Improvements in apparatus for separating fine material
IPC: B07B4/02
Filed: 1921-08-16
Abstract: 179,867. Mower, G. A., and Ogilvie, A. Aug. 16, 1921. Pneumatic separating. -In separating-apparatus of the type in which the material thrown outwards by a number of superposed centrifugal spreaders intercepts a vertical current of air caused by a fan carried at the upper end of the shaft on which the spreaders are mounted, the whole of the current of air delivered by the fan is constrained to pass downwards between an inner and outer casing enclosing the spreaders and then upwards from under the lowermost s-preader to each spreader in succession until it is drawn into the fan. Also in apparatus of this type and in which the coarse material is discharged from a spreader plate against a conical downward deflector arranged in the ascending current of air, such material is discharged on to another conical deflector from which it is discharged outwardly on to another rotary spreader. The material is fed in by the hopper 26 on to a spreader 28 which consists of a ring 15 and a disc 28 separated by radial strips 29. This spreader throws the material against the conical ring 14 which deflects it downward on to another conical ring 16 which may be perforated or serrated, the material falling between this and a cylindrical ring 17 on to another spreader disc 18. The material is thrown outwards by this disc against the cylindrical ring 19 at the top of the cone 20. A cylindrical casing 4 encloses this apparatus and is attached at the bottom to the hopper 5 and spout 6, a valve 21 consisting of two slotted rings, one adapted to move over the other, being fitted between the hopper and the casing. A fan 13 covering the top of the casing 4, draws a current of air up through the descending material, the lighter particles being carried upward through the fan and discharged into an annular space between the casing 4 and an outer casing 1 which terminates in a cone 2 with an outlet 3. The current of air passes under the lower end of the casing 4, through the valve 21 and again up through the streams of material. The heavier particles fall into the hopper 5 and the lighter particles are collected at the outlet 3. To prevent any large pieces of material from entering the apparatus, a small defector ring 27 is fitted on the shaft 9 in the cone 7 and serves also to feed the material to the first spreader disc.

Title: Method of applying a coating of fluorocarbon resin material to an article
Inventor: FLOYD TERENCE JOHN
IPC: B05D5/08
Filed: 1962-06-07
Abstract: A low friction and corrosion resistant valve plug is made by rendering the surface of a metal core porous and then bonding thereto a layer of polytetrafluoroethylene containing fibrous material.  If the metal be aluminium, it is made porous by etching with caustic soda.  If it be stainless steel, then it may be sprayed or sintered with molten or powdered stainless steel.  A dry layer of woven glass fibre is applied to the core which is then dipped in an aqueous dispersion of the resin, subjected to temporary vacuum so that thereafter air pressure forces the resin into the pores and then cured under heat and pressure.  According to the Provisional Specification the core is coated with polytetrafluoroethylene or other thermosetting resin and then a preformed polytetrafluoroethylene film, reinforced with glass fibres, is bonded thereto.  Before application, the inner surface of the film is roughened, e.g. by grinding to produce a nap of glass fibres.

Filed: 1924-09-18
Abstract: 222,134. British Thomson-Houston Co., Ltd., (Assignees of Hewlett, E. M.). Sept. 18, 1923, [Convention date]. Inductances.-An inductance coil particularly for use in exposed positions is constructed to provide efficient spacing and insulating means between the turns and to prevent short-circuiting by falling water. The coil is supported on insulators comprising ribs having conductor-retaining grooves of greyer length than the thickness of the ribs and central projections upon which the conductors rest. The coil is built up around six insulating posts 1 the lower ends of which are surrounded by porcelain insulators 10 and terminate in bases 7 which can be secured to a foundation by bolts 8. The posts 1 are held in position bv metal bands 11 having insulating joints 12 to prevent losses due to induced currents. The two lower bands 11 are secured to the posts by clamping rods 13 and insulators 14, the rods 13 being insulated from the bands 11 to avoid induced currents. The turns of the coil are supported upon insulators 15 which are provided with grooves 16 on opposite sides as shown in Fig. 5 and are formed with openings 18 to receive clamping bands 19 as shown in Fig. 3 which are attached to yokes 20 surrounding spacing blocks 22. The insulators 15 are triangular in shape as shown in Fig. 5 so that the inner turns in the upper and lower grooves are further apart than the turns in the outer pair of grooves. The grooves in the upper side of the insulators 15 are staggered in relation to the grooves in the lower side to prevent shortcircuiting by icicles due to dripping water. The creepage surface over each insulator 15 is increased by a central rib 28, a grooved barrier 29, a second barrier 30 and projections 31 within the grooves 16. Depressions 33 in the barrier 29 collect falling water and break it up into separate streams. Additional grooved barriers may be provided between superimposed insulators.

Title: Cutting device
IPC: B28D5/04
Filed: 1964-05-29
Abstract: 996,696. Severing by abrasion. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 29, 1964 [June 27, 1963], No. 22277/64. Heading B3D. A device for cutting a workpiece includes a disc, wheel or the like rotatably mounted on a mounting means, said mounting means permitting yielding movement of the disc, wheel or the like away from the workpiece and being operable to urge the disc, wheel or the like yieldably with a light force towards the workpiece, means to support the workpiece for movement relative to the disc, wheel or the like, and means to direct a slurry containing abrasive particles at the disc, wheel or the like so that said light force is counterbalanced and the disc, wheel or the like is supported in a " floating condition and so that the particles are accelerated and directed on to the workpiece to erode the latter in a zone where the cutting is to take place. The device may be used for cutting a semiconductor body, e.g. of silicon or germanium, mounted on an epoxy plastic or glass substrate; a disc of stainless steel or non-ferrous high cobalt cutting tool alloy has a peripheral speed of 10,000 linear feet per minute, and the slurry is silicon carbide in water. An element 42 comprises stainless steel discs 44, each of approximately 2 mils thickness and 4 inches outside diameter, with interspersed spacers 46 exposing approximately 20-40 mils. of the discs. The element 42 is mounted on a shaft journalled in a casting 56 pivotally mounted in a part 60 attached to a platform 80. The shaft is driven through belt 48 by a motor 54 mounted on a plate 66 pivoted to the casting 56 and adjustable by means 68 to tension the belt. A spring tension element 72 acts on an arm 70 fixed to the casting 56, and is adjusted so that the element 42 has a downward force of approximately 10 ounces per disc. The end 74 of the arm 70 actuates through a plunger 76 a displacement gauge 77 carried by the platform 80. If the cutting discs come into contact with the wafer being cut the resultant bouncing is indicated on the gauge 77. Wafer 81 and its substrate 82 are mounted on a table 84 secured to shafts 86, 88 slidable in the platform 80 by means not shown to pass the wafer 81 below the element 42. Bellows packings are provided. A nozzle 94 is attached to platform 80 and slurry is introduced into the nozzle through tube 96 from a pump. The velocity with which the slurry leaves the nozzle is sufficient to overcome the windage created by the high speed rotation but insufficient of itself to perform cutting; it is preferably 30 feet per second. During a set-up run, the feed rate of the wafer is set as low as possible, e.g. less than 1 inch per minute. As cutting begins, the feed rate is increased until the gauge 77 indicates bouncing, whereupon the feed rate is slightly reduced. With the data given above, a feed rate of 3 inches per-minute is satisfactory.
