IPC: G01B3/48
Filed: 1944-09-04
Abstract: 585,098. Linear - dimension gauges. HOWELL, H. Sept. 4, 1944, No. 16874. [Class 106 (ii)] A plug gauge for use in the measurement of internal diameters of either plane or screw-threaded bores comprises two' or more members or segments 1 each having an external face shaped to fit the bore, an internal face of conical form, and a flat face 2, the faces being'so arranged that when the members are in contact by their external faces with a bore of the correct diameter and have their flat end faces in one plane, the internal faces form parts of one and the same conical surface, and a sphere or other shaped member 6 for pressing the members 1 apart to fit the bore having a stem 7 which according to the extent it protrudes beyond the flat face 2 (or a plate overlying same) gives an indication of the diameter of the bore. As shown, there are three segments 1 held together by spring rings 3, one segment being held by a screw 5 to a plate 4, and the apex angle of the hollow cone preferably is 53 degrees 8 minutes. When in use the extent to which the stem 7 extends beyond the plate 4 is measured by a comparator or dial gauge. Modifications are described where the external faces are screw-threaded for use in measuring bores of female threads. In one form the gauge comprises a top plate, a cylindrical body which can enter the bore, a transverse slot through the body in which are fitted two segments each having inner conical faces and outer screw-threaded faces, and a sphere provided with stem adapted to move the segments apart.

Title: Process for electrolytic production of titanium
IPC: C25C3/36
Filed: 1953-06-19
Abstract: 756,943. Electrolytic production of titanium. REYNOLDS METALS CO. June 19, 1953 [June 24, 1952], No. 16971/53. Class 41. In a process for producing titanium or titanium alloys wherein a titanium chloride of valency lower than 4, mixed with an inorganic anhydrous salt melt, is electrolytically decomposed, titanium tetrachloride is introduced into an electrolytic cell and contacted with a liquid metallic cathode of metal or metal mixtures which are not capable of dissolving titanium to a substantial amount but absorb titanium in the form of a suspension, the cathode containing at least one metal capable of reducing titanium tetrachloride to produce the lower valency chloride or chlorides of titanium and simultaneously therewith a chloride of the reducing metal, and the chlorides mixed with the salt melt and electrolytically decomposed, the titanium being separated from the suspension. The inorganic salt melt may consist mainly of aluminium chloride, with other salts such as sodium, potassium, lithium and ammonium chlorides. The liquid cathode may be mercury, through which the titanium tetrachloride is bubbled, the mercury reducing it to tri- and di-chlorides and forming mercury chlorides. Subsequent electrolysis produces titanium metal at the mercury cathode, the mercury chlorides being decomposed to mercury again. Some aluminium may be electrodeposited at the cathode, or may be provided in the mercury cathode as an amalgam, the aluminium also reducing the titanium tetrachloride to lower chlorides. In the electrolysis nobler metals, such as mercury, may be deposited before the titanium. The cathode may also be an amalgam of magnesium and mercury, or a magnesium-zinc eutectic, or Wood's metal, or any liquid metal mixture containing metals such as mercury, magnesium, zinc, cadmium, tin, antimony, aluminium or silver, which will reduce the titanium tetrachloride to lower chlorides. In a modification the titanium tetrachloride is contacted with the reducing metal to form the lower chlorides, before mixing with the molten electrolyte.

Abstract: 976,408. Tablet dispensers. MILES LABORATORIES Inc. May 4, 1962 [May 24, 1961], No. 17255/62. Heading B8P. A tablet dispenser comprises a container portion 4 slidable on a post 6 mounted vertically in a base portion 2. The top 14 of the container slopes inwardly towards a central aperture 16. To dispense a tablet, the container is moved to the top of the post and then lowered, when a tablet will be left in a depression on the top of a flange 18 on the post. The base is of an opaque rigid plastic, the post is of any similar rigid material and the container is made of a rigid transparent plastic or of glass. A sleeve 12 sliding on the post may be moulded as part of the container or may be attached thereto. A bayonet-slot on the post cooperating with a stud in the sleeve necessitates twisting the container before it will slide on the post. As an added precaution, pins integral with the bottom 8 of the base are wedged or welded into holes in the sleeve and have to be broken by twisting the container relatively to the base when the dispenser is first used. The aperture 16 facilitates filling but a press-in top may be provided when the dispenser is filled prior to sale. The base may be weighted at 24 with lead.

Abstract: 1509224 Absorbing CO 2  A-T-O Inc 28 April 1975 [29 April 1974] 17581/75 Heading C1A [Also in Division B1] A device for removing exhaled CO 2  from a breathing zone comprises a vessel having an inlet for exhalation, a first bed containing LiOH, a second bed immediately downstream of the first bed containing hydrated sodium aluminium silicate molecular sieve, and an outlet, the volume ratio of LiOH:sieve being about 2:1, and the hydrated sieve containing 40-60 moles H 2 O per mole of sieve. The device is used in a method of absorbing CO 2  from respiratory gases in which CO 2 -containing exhalations are introduced at a breathing zone into a gas stream that is recirculated between breathing and absorption zones. In an example, the device is a canister in which a wire mesh screen separates the two beds. Passage of CO 2  exhalation through the beds in the order stated appears to result in the formation of LiHCO 3  by endothermic reaction, instead of Li 2 CO 3  by exothermic reaction, giving improved temperature control in a closed breathing system.
