Title: Method and device for manufacturing a hollow article
IPC: B29C49/02
Filed: 1963-07-16
Abstract: A method of making a hollow article in a die open at one end comprises immersing the open end of the die 5 to a controlled depth in a bath of molten material and conducting a predetermined quantity of a pressure fluid into the bath and below the die so as to form a bubble of the molten material and to apply the bubble against the inner surface of the die where it solidifies. The article may be closed by applying a plate 9, Fig. 4, to the open end of the die thereby trapping a layer 10 of the melt. The die may be a hallow metal, vitreous or glass object which is to be coated with an inner lining. The preferred melts are alloys e.g. of nickel, titanium, aluminium which when exposed to a fluid such as oxygen form a film-like layer of a compound such as an oxide on the surface of the bubble. The pressure fluid may contain constituents which become incorporated in the metal during blowing e.g. sulphur containing gases such as sulphur dioxide, hydrogen sulphide. Other fluids mentioned are inert gases such as helium, argon, CO2, CO, hydrocarbon gases such as methane and its combustion products, halohydrocarbons such as fluoro and chloro methane and ethane, halogens like chlorine, bromine, fluorine, hydrohalogens like hydrogen chloride, rare earth halides, like germanium chloride, metal-organic compounds etc. liquids such as silicone fluids or polysiloxanes which remain stable at the temperature of the melt or decompose to form gases or reactive elements, fluidized solids such as gases containing finely divided metal, metal oxide etc. Inert gas may be applied to the die interior, or suction to assist the pulling of the bubble thereinto. In a modification, Fig. 7, a globule 4 of glass or other vitreous material, high melting point plastic, metal or alloy, is placed on the end of the blow tube 2 and is blown into the die, the bubble picking up an adherent lining of aluminium alloy from the bath 1 so as to obtain a glass etc. lined aluminium alloy article. This article may then be used as a die for a subsequent blowing operation to produce for example a glass object having thin inner and outer layers of metal alloy. Alternately the bubble may be blown into a plastic, metal or metal alloy die which then forms part of an article having a glass-lined metal alloy coated insert. A machine for the continuous production of hollow articles from aluminium alloy comprises, Figs. 11, 13, a moult 33 vertically movable by rack and pinion 47, 48, a molten metal bath 31, and a blow pipe 26 to which predetermined qualities of a mixture of 97%N, 3%O may be fed under the control of a timed valve 23. The blow pipe has a cap 28 made of non-wettable material with capillary openings therein, and a wettable insert ring 55 e.g. of copper, steel, glass, which the end of the bubble contacts. The invention is stated to be applicable to the manufacture of cans, light sockets, ash trays etc.

Title: Distortion measuring devices
IPC: G21C17/08
Filed: 1964-03-10
Abstract: In a nuclear reactor control rod channel distortion measuring device a telescopic tube is inserted into the channel and the relative lateral displacement between the tube ends is measured optically to give a measure of the core distortion. A light beam is directed down the tube and reflected back up the tube from a reflector at the inner end. The reflected image is photographed at the upper end and indicates the radial displacement of the centre of the reflecting surface from a datum centre line. The telescopic sections of the tube are extendable by means of a cable which is attached to the innermost section and which is wound on a drum, coupled to the camera shutter, and wound manually, by gearing, from the reactor outer surface. To reduce refraction effects along the light beam, due to temperature gradients inside the reactor, the telescopic tube is helium filled. To investigate channels which are not vertical the telescopic tubes may be extended by a rack and pinion. Infra-red radiation may be used in place of light.

Patent ES-348679-A1 (ES)
Title: Impression control mechanism
IPC: B41J7/94
Filed: 1967-12-27
Abstract: A power driven typewriter, in which a selected serrated cam 41 coacts with a continuously driven power roll 47 to effect an impression, includes impact adjustment mechanism responsive to a case shift wherein a greater striking force is initially applied to the type bar 11 when in the upper case and a stop finger 61 responsive to the case shift disengages the cam from the power roll after a time of contact such as to compensate for the increase in striking force applied, adjustment also being effected during a case shift operation. The impression density of each character is controlled by a finger 61 resting on an individually adjustable upper or lower case stop screw 57, 59 by engaging a heel 63 of the cam 41 to disengage the cam from the power roll. The stop screws 57, 59 are mounted on a bar 56 which is rocked about a pivot 71 by the case shift mechanism. The position of the bar 56 is adjustable by an impact control lever (105), Fig. 2 (not shown), for collective adjustment of the impression density as described in Specification 1,169,810. The case shift mechanism rotates a plate 23 mounted on a shaft 25 to move the pivots 13 of the type bars through linkage (not shown). A pin 79 on the plate 23, moves a link 73 after a delay caused by lost motion in a slot 83 by sliding in a slot 85, the link 73 being connected to the bar 56 through a bracket 77, thus rocking the bracket about the pivot 71. The delay enables the impression density to be correct when case shift and character keys are redepressed simultaneously.
