Title: Improvements relating to draw-out trucks for electric switchboards
IPC: H02B11/133
Filed: 1926-10-01
Abstract: 271,705. Johnson & Phillips, Ltd., and Wood, P. M. Oct. 1, 1926. Sliding switch-carriage arrangements.-Interlocking gear between the circuit-breaker, selector switches and movable and fixed switch gear portions of truck-type switch-gear is arranged to be operated by a removable key. As shown in Figs. 1 and 2 the truck member 1 carries a pivoted locking plate 3 which operates sliding bars 7, 8 to engage behind the sides 2 of the fixed switchgear structure and lock the truck in position. The plate 3 can only be moved to its unlocked position when slots 29 in a bar 28 are moved opposite the plate by the circuit-breaker in its opening movement. The selector-switch operating mechanism comprises a handle 31 with a crank 32, Fig. 2, connected by a slotted link 33 to a lever 35 linked to the contacts. A cross pin 39 works in the slot in the link 33 this pin being carried by the upper end of a sliding rod 41 which has its lower end bearing against the end of the bar 7 so that the selector switches can be operated only after the bar 7 has been moved to its unlocking position. The ends of the bars 7 and 8 pass through recesses 11, 12 in the sides 2 as the truck is withdrawn and carry rods 7', 8<1>, Fig. 2, for preventing the inward movement of the truck member while the circuitbreaker is in the closed position. The plate 3 is operated by a key 9, Fig. 7, having profiled portions 13, 14 for insertion in a corresponding recess in the lock cover-plate 10, Fig. 6. On rotation of the key the projections 13, 14 engage and move aside locking pawls 17, 18 before engaging the projections 24 on the shaft carrying the locking plate.

Abstract: 393,138. Mincing food. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Smith's Sons Co., J. E. ; 50, Broadway, Buffalo, New York, U.S.A.) Aug. 31, 1932, No. 24335. [Class 28 (ii).] In a food-cutting machine a rotary bowl having a central discharge opening is provided with a closure member which surmounts the bowl and is movable over and toward and from the same into and out. of its closed position. As shown, a bowl 10 is provided with a wormwheel 26 driven by a worm 25 and is supported on adjustable rollers 28. A cover 15 supports a shaft 13 driven by a belt 21 from the worm drive, the shaft 13 carrying cutting knives 17 enclosed by a hinged cover 18 which forms a support for a curved rod 37 pivotally attached to a plug 36 normally closing a central discharge outlet of the bowl. The plug is balanced by a weight 50 and is operated by a handle 45 attached to a cable 39 led over pulleys. In the raised position of the plug it contacts with a scraper 61 on the cover 18 and is rotated by a handle 62 in the bottom of the plug in order to remove food adhering to the surface thereof. An additional guard 65 is formed as an extension on the cover 18. In a modification the rod 37 is pivoted to a radial arm hinged to the shaft 13, the arm being connected to a horizontal rod with handle and the balance weight 50 is attached directly to the rod 37.

Title: Improvements in the manufacture of anisotropic permanent magnets and in alloys therefor
Inventor: DEAN WILLIAM THOMAS
IPC: C21D8/12
Filed: 1948-09-16
Abstract: An iron-base alloy has the following position Al 6-11 per cent; Ni 10-20 per cent, Co 16-30 per cent, Nb 0.5-10 per cent, Cu up to 7 per cent, Ti up to 5 per cent, Fe, and impurities, the remainder.  The alloy may contain one or more of the elements W, Cr, Mo, V, Zr, Ca, Ce, Ta and Si up to 0.5 per cent of each and less than 1.0 per cent in total.  Anisotropic permanent magnets may be produced by subjecting the alloy to the action of a magnetic field while cooling through a temperature range from above the Curie temperature down to about 600 DEG C. followed by an ageing treatment at 600 DEG C. or thereabouts.  The alloy to be subjected to this treatment is preferably cast in a mould and caused to solidify under conditions in which heat is abstracted in substantially one direction only.  The heat-treated alloy is subsequently magnetized in the direction of the magnetic field applied during cooling.  Specifications 522,731 and 660,580 are referred to.

Title: Moulding stretch-deformable film material
IPC: B29D/
Filed: 1977-06-14
Abstract: The method for forming a film (p) of flexible and deformable material, by drawing, into an open container intended for packaging a food product, consists in moulding the film in a mould cavity in order to form therein a recess having a surface whose area and perimeter (10, 15, 16, 13) are essentially equal to those of the internal surface (10, 11, 12, 13) of the desired container. That part of the mould cavity corresponding to a join between a side wall and the base of the container has a radius of curvature greater than that of this join. In each corner of the cavity, the surface of the cavity has a protrusion (18) extending into the cavity. During moulding, the film is moulded around these protrusions (18) in order to form folds (pleats) having opposed sides. After having withdrawn the moulded film from the cavity, the opposed sides are opened out in order to obtain the desired container. This method enables a moulded container to be obtained from a plastic film having approximately equal wall thicknesses. <IMAGE>

Title: Improvements relating to glass-to-metal seals
Inventor: SCOTT WILLIAM JOSEPH
IPC: C03C29/00
Filed: 1962-06-28
Abstract: <PICT:1039293/C1/1> A glass-to-metal seal comprises a circumferentially continuous fillet of glass sealed to and maintained under compression between overlapping tubular metal parts, in which one of the metal parts only, without the other part, forms a wall supporting at least a portion of the boundary of the fillet while an end of the other part is wholly embedded in and sealed to the fillet. In one example, being the cathode seal of a mercury arc rectifier, a coaxial tubular portion 5 is hermetically sealed at one end by welding on to the steel circular base 4 of the cathode pool, the other end being received by a channel 7 provided upon the adjacent circular rim 8 on the aperture 9.  The channel 7 is provided by outwardly flaring the tubular end section 10 of rim 8, the channel being contained between the inner wall of section 10 and the outer wall of a refractory tube 11 (e.g. graphite). By inverting the apparatus, glues can be poured into the channel, or fed in as a ring and then fused, the end of tubular section 5 then being contained within the glass.  Preferably the glass easily wets the parts 5 and 8 but not part 11.  The glass has a lower expansion then the component part 8.  If necessary the parts 5 and 10 may be coated with a vitreous enamel to aid wetting.  The glass may be fused by heating the parts 8, 5.  To provide a long leakage gap the refractory part 11 may be removed after the seal is formed.

Abstract: Substances, such as oils, resins, pitch, wax, wool grease, or fatty acids, are distilled under a pressure of 8mm. of mercury or less by causing them to trickle in layers of 1 mm. thickness or less over members of good heat conductivity, such as Raschig rings, which are heated to evaporating temperature, the vapours being passed directly to a refining treatment where part of the vapour is condensed and returns <PICT:0429720/III/1> to the still, thus washing the gas and carrying raw materials carried over back to the still.  The liquid is preheated in a boiler 1 and then flows to the vacuum still 2 which is heated by a furnace 14 and is filled with Raschig rings. Unevaporated liquid flows from the still to tanks 4.  The vapours flow to a refining cell 3 filled with Raschig rings in which partial condensation takes place and the raw materials are carried back to the still with the condensate.  The vapours then pass through coolers 5 and 7, the condensate from each stage being collected in tanks 6 and 8 respectively.  The whole apparatus is maintained at a low pressure by the vacuum pump 10.
