Title: Improvements in jaw crushers
IPC: B02C1/04
Filed: 1935-05-31
Abstract: 438,700. Crushers with vibrating jaws. KEET, T. W., 20, Victoria Building, Commissioner Street, Johannesburg, South Africa. May 31, 1935, Nos. 15894 and 15895. Convention dates, Sept. 18, 1934 and May 15, 1935. [Class 59] In a jaw crusher means are provided for relatively reciprocating the upper surfaces of the jaws towards and from one another and for reciprocating the lower crushing surface of the one jaw toward and from the other jaw, the lower crushing surface of the other jaw being reciprocated substantially linearly in its own plane. As shown, the jaw 2 is pivoted at 6 and reciprocated at its lower end by a pitman 8 operated by an eccentric 7. The jaw 3 is mounted at its upper end on an eccentric 13 and reciprocates substantially linearly at its lower end on a pitman 14 pivoted at 15. The eccentric 7 is driven at a faster rate than the eccentric 13 by pulleys 22, 24. The discharge gap 20 is adjustable by the movement of the pivot 15 by means of a bellcrank lever 29, 30, the arm 30 being adjustably positioned in a quadrant 34 by means of a nut and washer. When an uncrushable object enters between the jaws the frictional grip of the nut and washer holding the lever 30 in the quadrant 34 is overcome and the pivot 15 recedes to open the jaws. The jaws are retained against their respective pitmans by spring-controlled rods 26, 27.

Title: Production of metallic titanium
IPC: C22B34/12
Filed: 1949-06-15
Abstract: For the thermal dissociation of titanium tetraiodide to produce metallic titanium (see Group II), the traiodide is produced by passing gaseous iodine into contact with titanium-bearing material at a temperature above the boiling point of the tetraiodide.  The gaseous product thus formed is either fractionally cooled, or fractionally distilled (preferably at 150 DEG C to 379 DEG C at a reduced pressure) to recover the pure tetraiodide.  The iodine liberated from the dissociated tetraiodide is recycled. Specifications 662,577, 662,579, 698,233, 698,234, 698,235 and 698,236, [Group II], are referred to.ALSO:Pure titanium is produced by passing a preformed gaseous product consisting essentially of titanium tetraiodide into contact with a surface heated to a temperature in the range of 1100 DEG C-1700 DEG C.  The deposition surface may be of tungsten or titanium.  The tetraiodide is preferably formed by passing gaseous iodine into contact with titanium-bearing material at a temperature above the boiling point of the tetraiodide.  The gaseous product thus formed is either fractionally cooled, or fractionally distilled to recover the pure tetraiodide.  The liberated iodine is recycled.  Specifications 662,577, 662,579, [both in Group III], 698,233, 698,234, 698,235 and 698,236 are referred to.

Title: Operating device for air blast electric circuit breakers
IPC: H01H33/867
Filed: 1955-06-03
Abstract: 770,100. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 3, 1955 [June 4, 1954], No. 15915/55. Class 38(5) In an air-blast circuit-breaker having contacts 1, 2 arranged in a compressed air container 3 and opened by the delivery of compressed air to an operating member 15 which opens a channel 19 between its. housing 5 and the atmosphere, thus permitting the pressure in the container 3 to open contact 2, the contact 2 is provided with a disc 7 which, when brought into contact with member 15 forms a space which communicates with the atmosphere through channels 28, 29 and 19 and pneumatically couples the contact 2 with the member 15 so that when, after a delay, the member 15 is restored to its original position, the contact 2 moves with it to remain open'until the supply of operating air is interrupted, when the space between the disc 7 and the member 15 is cut off from the atmosphere and brought into communication with the pressure within the housing 5 and the contact 2 is closed by spring 31. The operating air is delivered along pipe 12 to raise piston 11 and open channels 19, causing the pressure within housing 5 to fall. Compressed air in container 3 then moves the contact 2 and disc 7 down to seat against member 15. Compressed air also flows through channel 13 to the upper side of piston 11 so that when the pressure above the piston has risen, the pressure in container 3 causes the contact 2 and disc 7 to push the member 15 and piston 11 downwards and re-close the channels 19. In closing the circuit-breaker, pipe 12 is evacuated, lowering membrane 22 and valve 25 to allow compressed air to flow from housing 5 through channels 26 and 28. The pressure on the lower side of disc 7 then rises to equal that on the upper side and the disc is raised by spring 31 to close the contacts.

Abstract: 1,221,785. Stern tubes. GLACIER METAL CO. Ltd. 8 April, 1968 [10 April, 1967], No. 16300/67. Heading B7S. [Also in Division F2] A stern tube 3 is surrounded by an oil bath defined by an outer casing 4. Oil is drawn into the stern tube via the opening 8 and the pipe 11  which communicates with a region adjacent the periphery of the casing, and expelled from the tube via opening 9 and pipe 12. The exterior of the casing 4 being in contact with the water 6 is maintained at the same temperature as the water and so oil issuing from pipe 12 is cooled and flows round the bath in the direction indicated by the arrows 14 and 15, and the oil entering pipe 11 is therefore cooler than that adjacent to the bearing assembly. In a modification the inlet pipe 16 is diametrically opposite the discharge pipe 12, and in a further modification the pipe 12 is omitted.

Title: Method and apparatus for applying a particulate material to a food product
Inventor: WATKINS HARLEY EARL
IPC: A23L27/00
Filed: 1967-04-10
Abstract: 1,123,517. Coating foods. S. P. LIPOMA, H. E. WATKINS, D. L. WARD, P. C. MURRAY,. H. R. ROBERTS and J. T. "HOURIGAN [trading as LIPOMA ELECTRONICS CO.]. 10 April, 1967, No. 16327/67. Heading A2A. [Also in Divisions B2 and B8] Particulate material is applied to a food product by establishing a recirculating stream of air, introducing the material into the stream to be carried in suspension thereby to the food product, and establishing an electrostatic field in a region of the stream to charge the particles. Thus salt, pepper, cheese, cinnamon, sugar, preservative or food colouring may be applied to potato chips, corn chips, :potato products, grain cereals and apple slices (as the case may be). Food products are delivered batchwise off a feed belt 10, Fig. 1, into a hopper 25, Figs. 1, 4 and 6, wherein they are treated with charged particles of flavouring circulated by air through the conduits 16 and 17 (as indicated by the arrows) and after treatment the hopper 25 is turned over to discharge the treated food products on to a further conveyer 21. For the electrification, particles of flavouring held in a bin 45 are sucked with air through a blower and thereafter charged by passage through a corona discharge of 30,000 volts potential. Direct or alternating current voltages may be applied, for example between a metal -tube and two electrodes fitted within a non-conducting plastics flow conduit (Fig. 8, not shown). The hopper assembly consists of two rotatable baskets placed back-to-back, each including a truncated conical portion 62, Fig. 6, a screen 64 and a hub 67 from which flat plates 69 extend radially. The impact of air and particles on the flat plates in circulating from the tangential inlet 88, Fig. 1, causes the assembly to rotate about the axis 72, whereby the food products on the upper screen 64 are uniformly treated. After the treatment the assembly .is turned over about an axis (76-78, Fig. 7, not shown) perpendicular to the axis 72. A slitted rubber gasket element 84, Fig. 4, for guiding the food products into the hopper is deflected to allow this rotation of the assembly. The .chamber 12 housing the hopper assembly is normally maintained against substantial air leakage by a door or flap 90 and an elastic gasket bonded to the periphery of a disc 74, Fig. 6, so as to contact the inner surface .of the wall 80 of the chamber. A pivoted, generally channel-shaped baffle 96 assures the retention of the food products on the feed belt until the products are allowed to fall into the upper basket. In a further embodiment (Figs. 9 to 12, not shown) charged condiment particles are blown into an earthed container (C) filled with the food products.

Title: Improvements in and relating to devices for supplying adhesive labels or strip material
IPC: B65C11/04
Filed: 1919-06-30
Abstract: 151,382. Mond, A. L., (Liberty Paper Co.). June 30, 1919. Feeding and registering webs.-Relates to devices for holding a supply of dry gummed tape and delivering it in adhesive condition as it is drawn forth, and of the kind in which the tape is supplied from a roll, led over a moistening roller, and can be raised into contact with the serrated end of a cutting-blade for severing the moistened portion. As shown in Fig. 1, the tape is drawn from a supply roll 26 supported between a pair of uprights 12, and thence passes under a guide roller 27, over a platen 15, and under the cutter-bar 24 to the moistening roller 14, the cutter-bar being so mounted on horizontal pivots 25 that on drawing the tape over the moistening roller the cutter-bar rocks and its rear edge nips the tape against the platen, thereby tensioning the tape so that it may be firmly contacted with the moistening roller. The tape roll is supported on stub axles 38, Fig. 3, carried by disks 35 provided with pins 34 adapted to engage in any pair of a series of oblique slots 32 in the uprights 12, according to the diameter of the roll. Guides 20 are provided on the platen for the edges of the tape, and are adjustable laterally by means of slots 22 and fixing screws 21 for tape of different widths. The feet 12' of the roll-supporting uprights 12 are similarly adjustable laterally by means of slots 41 and bolts 42. Symmetrical adjustment of the uprights 12 and platen guides 20 is facilitated by scales 39<1>, 22<1> alongside the slots 41, 22. The platen 15 enables the tape to be written upon.

Filed: 1923-06-25
Abstract: 217,061. Rogers, F. H., (Schweitzer & Conrad). June 25, 1923. Fusible cut-outs; cases; couplings.-Cut-outs of the kind described in Specification 4483/15 have the terminal members for the fuse element and for the flexible conducting element formed with open ends in which the fuse and its strain wire or the flexible conductor are or is secured by deforming the terminal member, for example by swaging. In one form the fuse terminals 9, 10 are open tubes which are crushed to secure the fuse and strain wires 18, 19. The upper terminal for the flexible conductor 8 is a tube 15 similarly treated and the two are secured together by a scre.w 16 clamping between them the upper end of the tension spring 11. The lower conductor terminal is a tube with a screwed portion 6 to engage the lower terminal cap 4, and a plate and screw 13, Fig. 6 clamp the lower end of the spring 11 to the crushed end 7 of the terminal. The upper terminal cap 2 has an internal flange 28 upon which an S- shaped spring terminal member 30 rests. Two holes 38, 34 are formed in the fuse terminal 9 and a tool is engaged with the lower hole 38 to draw the fuse up and align the upper one 34 with a hole in the terminal member 30; a screw and nut 32 secure the parts in this position. A vent cap 27, flanged and bulged to enable a spring to fit in the bore of the terminal cap 2, is applied, the fuse being filled with an arc extinguishing liquid. A non-drying viscous cement seals the vent cap and tends to rupture at a fairly definite pressure. A liquid-spraying member 22 is carried by the arcing terminal 10 of the fuse and the fuse is confined within a non-conducting plug 21, preferably of cork. In a modified construction the flexible conductor is secured in terminals 51, 61 in the manner above described. The former carries a block 56 having pins 60, 61 which co-operate with certain turns of the coil tension-spring to secure it, a screw 58 assisting in the fastening. The spring is similarly secured to terminal 67. The upper end of this terminal is tipped to take a screw 85 which clamps the centrally-perforated portion of a fuse strip 86 secured by screws 87 across the interior of the upper terminal cap 75. The terminal 67 is perforated for a strain wire 83 secured by screws 84 across the cap 75. The arcing terminal 67 carries a liquid-spraying member 88 and is guided by fingers 92 each pair being formed by a wire passed through holes drilled at right angles to each other through the teminal 67.

Abstract: 1,124,886. Heat-treating oriented thermoplastic films. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 March, 1967 [15 April, 1966], No. 16602/66. Heading B5B. Apparatus for heat-treating an oriented film of a crystallizable or crystalline organic thermoplastic polymer comprises at least one mattsurfaced rotating roll positioned between feed and take-off means for the film, and maintained at a temperature (below the m.p. of the film) which would cause the film to shrink, means being provided to force the film on to at least one of the rolls, and to spread the film uniformly on at least one of the rolls on to which the film is forced. Specified thermoplastics are polyolefins, polyesters and nylons, of which examples are given. The "forcing-on" means may be an electrostatic charge applied, e.g. by means of a charged wire, knife-edge or row of needles, to the side of the film not in contact with the roll, which is earthed, or may be the tension in the film, especially when small rolls, e.g. of 6 inch diameter are used. In this case the matt rolls may be idler rolls. The spreading means may be a banana or bow roller, or may be a soft material pressing on the film, when it is on the matt roll(s), e.g. a polyether foam coated idler roll. The feed and take-off means may be conventional nip-rolls, with, e.g. three matt rolls between them (as in Fig. 1, not shown). The matt effect may be provided by grit-blasting of, e.g. mild steel, cast iron or aluminium rolls, or may be matt paint. In passing from successive rollers, the speed of film travel is reduced to allow shrinkage.
