Title: Pulverising solid or molten materials
IPC: B02C19/06
Filed: 1964-02-05
Abstract: 1,055,123. Jet pulverizers. KOHLSWA JERNVERKS A.B. Feb. 5, 1964 [Feb. 5, 1963], No. 4929/64. Heading B2A. [Also in Division B3] A method of pulverizing solid material or molten material which is solid at ordinary temperatures comprises impinging against the material a liquid metal or alloy under pressure. The liquid metal or alloy is preferably mercury or an amalgam and is impinged preferably at a pressure of at least 5 atmospheres e.g. 10 to 20 atmospheres. The material to be pulverized may be austenitic stainless steel or a beryllium or cobalt-nickel alloy and may be heated before the liquid metal or alloy is impinged thereon. The powder produced is separated from the mercury and the separated powder is distilled in vacuo to remove remaining traces of mercury therefrom; the whole bulk of mercury may be distilled to separate powder possibly remaining therein. The apparatus shown comprises means for feeding downwards through a channel 10 in an insulating tube 1 a rod 9 to be pulverized and a supply pipe 11 for mercury under pressure which discharges into an annular channel 12 in a block comprising parts 2, 3 and 4. The channel 12 leads to an annular slot 13 from which the mercury is ejected to strike the rod 9. Inlets 6, 14 for protective gas discharge into annular channels 7, 15 respectively, the gas from the channel 15 flowing through a number of outlets arranged so that the gas has a helical motion around the rod 9. The slot 13 may be replaced by one or more discharge holes and the outlets 16 may be replaced by an annular slot. The slot 13 may have ribs 17 to impart a helical motion to the mercury. Vibrations may be generated by an electrical or mechanical vibrator acting on the block 2 to 4. A direct or alternating current, preferably of high frequency, may be applied to the rod 9 and block 2 to 4 (or the mercury).

Patent GB-373224-A (GB)
Title: Improvements in and relating to automatic gate and door opening apparatus
IPC: E05F13/02
Filed: 1931-02-20
Abstract: 373,224. Gate-operating mechanism and fastenings. STAPLES, E. H., 2, Ravensfell Parade, Bromley, Kent. Feb. 20, 1931, No. 5381. [Classes 44 and 65 (i).] Single or double gates are operated by a member pivoted below the surface of the ground and adapted to be engaged by the front wheel or wheels of a car, the consequent movement of this member being utilized to unbolt or unlatch the gates and being also transferred through links and levers to exert a direct pull on the hinge ends of the gates to open them after unfastening them. The contact member b, Fig. 5, is of inverted U-shape, and is fixed on a shaft b<1> running below the ground parallel to and a few inches in front of the gates. This shaft carries near its centre a cam b<4> engaging a link d which is connected at one end by a link d<1> to a bell crank e and at the other end by a link (not shown) adjustable in length to a lever g pivoted at one end. The free end of the lever g engages the bolt or bolts of the gates so as to retract them against the pressure of a spring. In operation, when the member b is moved, the link d is pressed down, and at first this link pivots about its connection with link d<1> so that lever g is operated to unfasten the gates ; the lever g then meets a stop, so that the right-hand end of the link d is held stationary, and the crank e is then operated by further movement of the cam. The movement of the other arm of the crank may be utilized to open garage doors by any suitable mechanism (not shown) ; in this case a spring is incorporated in the door operating gear to hold the crank e and link d<1> stationary while the lever g is being operated and to return the parts to normal when the member b is raised after operation. If it is not desired to operate the garage doors, the crank e and link d<1> are dispensed with, and a spring is placed beneath the left-hand end of link d. At each end of the spindle b<1> is another cam h, Fig. 6, acting on a system of links and levers as shown to give a direct pull on the heel of the gate a. The cam h has a slight clearance from the lever h<1>, to allow the cam b<4> to unfasten the gate before the cam h commences to open it. The contact member b folds down on to the ground when operated, out of the way of the car, and so long as it is down the gates are held open ; this member preferably remains down until lifted by hand, but may be provided with a spring and time-release catch for automatic return after passage of the car. When the operating member is lifted, the gates are freed, and may be closed by hand or preferably by springs. The gates may be opened by hand after the bolt has been withdrawn, for example by foot-pressure. Specification 360,644 is referred to.

Title: Process for molding synthetic linear plyesters
Inventor: PICCARD JOHN AUGUSTUS
IPC: C08J5/00
Filed: 1951-03-06
Abstract: Polyethylene terephthalate is obtained in crystalline form by heating in a mould a film of amorphous linear polyethylene terephthalate having an intrinsic viscosity of at least 0.3 and preferably 0.4-1.5 and removing the moulded film from the mould before cooling.  The film may be used in the production of gramophone records and coat buttons.ALSO:A crystallizable thermoplastic material comprising essentially a major proportion of substantially amorphous linear polyethylene terephthalate having a certain intrinsic viscosity is heated in a mould under pressure until it crystallizes, and then removed from the mould without cooling.  The temperature of heating may be between 120 and 220 DEG  C., e.g. between 150 and 200 DEG  C. At these temperatures the amorphous material becomes soft or molten and resolidifies soon after.  The resolidification occurs without the aid of cooling, because when the material becomes crystalline its melting-point is considerably above the moulding temperature. The intrinsic viscosity is at least 0.3 and preferably 0.4 to 1.5, and is a measure of the degree of polymerization of the polyester: it is defined as limit <FORM:0684651/V/1> as C approaches O where e r is the viscosity of a dilute solution of the polyester in phenol-tetrachloroethane (60 : 40) divided by the viscosity of the phenol-tetrachloroethane mixture per se measured in the same units, and C is the concentration in grams of the polyester per 100 c.c. of solution.  The linear polyethylene terephthalate may be that described in U.S.A. Specification 2,465,319, or a linear co-polyester in which ethylene terephthalate is the major and characterizing ingredient. Copolymers which contain a second glycol and/or dibasic acid component may be used.  A list of suitable glycols and acids is given.  The material may be moulded in sheet, slab, flake or powder form.  A sheet may be formed by cooling the molten material between cold aluminium sheets, this chilling keeping the polymer amorphous and transparent.  The manufacture of phonograph records and buttons is described.

Filed: 1918-03-27
Abstract: 131,030. Sperry, E. A., (Assignee of Davis, A. P.). March 27, 1917, [Convention date]. Arc lamps.-In a search-light or the like in which the positive electrode is fed or retracted by adjustment of the angular position of rollers constantly rotating the electrode, the roller frames are mounted in swivel bearings the axes of which pass through the electrode axis. The angular adjustment may be effected by a thermal device placed a little to the rear of the normal arc position. Manual control of the action of the thermal device may be provided for. In the form shown, an electric motor 51, Fig. 1, through reduction gear 90, shaft 16, and bevel-gear 17, drives one roller 13<1>, which is geared to the other roller 13 by a chain 18. Frames 14 carrying the rollers are pivoted in the wall of the hollow electrode-bolder and are urged inwards by springs compressed by caps 21. Handles 22 hinged to the pivots are turned outwards to draw the roller frames away from the axis by cam action when a new electrode is to be inserted. Laterally projecting arms on the frames are linked by rods 37 to opposite arms of a T-shaped lever 36, Fig. 3. The third arm of the lever is connected by links 34, 33 to a bent lever 27 pivoted at 28 and actuated by an adjustable spring 9 and by the thermal device. Pivoted to link 33 is a link 40 actuated through a lever 70, spring-urged rod 41, Figs. 1 and 3, lever 42, wire 43, and drum 45 by a rotary handle 47. As the controlling-springs 9, 50 are strong in comparison with the resistance of the rollers to adjustment, the link 33 acts as a lever about either point of attachment to the link 40 or lever 27, and hand or automatic adjustment may be independent or simultaneous. The thermal device may comprise parallel brass strips 23<1>, Figs. 1 and 3, on opposite sides of the positive electrode and bearing through knife-edges on a rocker 25, the lower ends of the strips being secured respectively to a fixed point and to the lever 27. Alternatively, a cylinder situated near the electrode and containing air, preferably at atmospheric pressure when the arc is normal, may be connected to an expansible vessel secured to an adjustable bracket and to the link 33. The positive electrode-holder is provided with cooling- flanges 10, 11, the front one being curved so as to cut off rays proceeding from the negative electrode and to serve as support for the thermal device. Two inclined contact slides 54 are pressed on to the electrode by spring-actuated levers 55. A silica or like sleeve protects the positive electrode near the arc. The negative electrode is fed by rollers 7 through a split holder 4.
