Title: Improvements in machines for grinding twist drills
IPC: B24B3/24
Filed: 1922-08-09
Abstract: 206,591. Oliver, E. C. Aug. 9, 1922. Drills.-The point of a twist drill is ground by means of a grinding-wheel which is oscillated, in the plane of the grinding-surface, transversely of the drill and at the same time is moved towards and from the drill, which remains stationary during the first stage of grinding and is then rotated to complete the grinding and to bring another lip into position for grinding. By this means the point is given the form shown in Fig. 10, the cutting edges 121, 122 being straight, and sections on planes 12, 13 showing a concave form, the part 53 being ground to an additional concavity in order to form a chisel point; the machine is arranged to operate on drills having 2, 3 or 4 lips.

Title: Improvements in and relating to illuminating appliances
IPC: F21V5/00
Filed: 1927-08-19
Abstract: 285,327. Holophane, Ltd., (Dorey, W. A.). Aug. 19, 1927. Globes and reflectors.-In a prismatic globe, adapted to illuminate substantially uniformly a street or like comparatively narrow area, a light source 7 is located at the centre of an inner hemispherical bowl 8 having a smooth interior surface 9 and an outer surface having upper and lower sections 12, 13 of annular refracting ribs with axes lying in the vertical plane containing the axes 17 of the maximum intensity required. The upper and lower lens surfaces 15, 20 and the annular refracting ribs adjacent the upper lens surface 15 are formed concentrically about the axes 17. The axes of the remaining annular refracting ribs are of successively increasing inclination with reference to the axes 17, and the angularity of their surfaces to the spherical surface of the bowl gradually increases, more moderately in the lower section 13 than in the upper section 12. The flange 27 of bowl 8 rests on the flange 28 of an outer hemispherical bowl 22 having a smooth outer surface 23 and having on its inner surface smooth sections 24, sections 25 of vertical prisms arranged parallel to and decreasing in angularity towards the vertical planes containing the axes 17, and sections 26 of radial prisms. The prisms in sections 25, 26 refract the light towards the vertical planes containing the axes 17, and these two sections may merge into each other. The two bowls 8, 22 are arranged so that the sections 24 come opposite the centrally disposed annular refracting ribs of the upper section 12, and a portion of the prisms in the lowest portion of section 25 may be cut away to allow a. portion of the light to be transmitted without vertical deviation. Instead of using two bowls the prismatic constructions may be arranged on the inner and outer surfaces of a single bowl. The globe may be used in combination with an upper reflector 32 which may be approximately hemispherical with its centre at or near the light source 7, or its lower part 33 may be circular and its upper part 34 elliptical or hyperbolic in vertical section.

Title: Improvements in the recovery of metals and metal compounds which are soluble in ammoniacal liquors
IPC: C22B3/14
Filed: 1927-08-24
Abstract: 301,342. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 24, 1927. Ammonium compounds containing metals. - The recovery of metals and their compounds, which are soluble in ammoniacal liquors, is greatly facilitated by a preliminary chlorination at an elevated temperature and subsequent treatment with ammonia, or solutions of ammonium salts or both. The individual metals may then be recovered from the resulting solutions in any known manner, for example, by precipitation or electrolysis. In the chlorination treatment, which may be carried out with any'of the usual reagents, the metals to be recovered, such as silver, nickel, cobalt, copper and zinc, are almost completedy chlorinated before any appreciable amounts of other constituents, such as calcium, aluminium, and magnesium compounds, are attached, with a consequent saving in the use of the chlorinating agent. The temperature should preferably be regulated so that no appreciable amount of the chlorides is volatilized, and the operation may be carried out under pressure. According to the nature of the material the process may be carried out under simultaneous, prior or subsequent oxidizing or reducing conditions which must be, so chosen as not to produce free metals. Before leaching, any base metal present in a low state of oxidation should be oxidized to prevent any precipitation of nobler metals already in solution; also, in the case of sulphur bearing materials, it is necessary to destroy any sulphides already present or formed during the chlorination or other preliminary treatment. The process is improved by leaching the chlorinated materials with water, preferably at an elevated temperature, before further treatment. This removes the chlorides from the materials to be treated with ammonia, and also prevents corrosion of the apparatus employed. In addition, the chlorination agents can be recovered from the aqueous solution in a form in which it can again be employed in the process; this occurs when basic materials, which have not been chlorinated, are present. If necessary, such materials, such as lime, may be added prior to or during the treatment with water, so that no heavy metal passes into solution. Any silver chloride which may remain in the aqueous solution of chlorides may be separated, for example, by cementation.

Title: Inhaler
IPC: A61M15/00
Filed: 1963-06-05
Abstract: An inhalation appliance associated with a pressurized aerosol medicament container has a discharge valve actuating button which simultaneously opens an air inlet vent.  The body of the appliance is formed essentially as two intersecting tubes 13, 14, Fig. 4 (not shown) and the upper end of the former fits closely on to the neck of an aerosol container 11.  The hollow valve stem 23 is received into a bore 30 in a hod-like member 18, its spring urging the latter downwards so that an annular flange 26 is normally held against a seating 40 in the bottom end wall of the tube 13.  When an external button 16 is pressed, however, the valve 23 is opened and the flange 26 is lifted clear of its seating, to admit air to the interior.  The mist of medicament passes out through a bore 33 and orifice 34 into the horizontal tube 14, which is gripped in the user's mouth so that, on inhalation, the medicament, together with the air through the valve arrangement 26, 40, is drawn into the lungs.  Recesses in the periphery of the flange 26 engaging vertical guide webs 44 ensure that the orifice 34 is directed towards the tube 14 by preventing rotation of the member 18.

Abstract: 366,442. Changing signs. RON, J. V., 36, Tetuan, and DIAZ, J. M., 23, Principe de Vergara, both in Madrid. July 28, 1930, No. 22687. Convention date, March 26. Void [Published under Sect. 91 of the Acts]. [Class 3 (i).] Relates to a signalling system for use on trains or other vehicles for indicating the next stopping place. Fig. 2 shows the apparatus provided on two coaches of a train. The front and rear of each coach is provided with relays 5 which may be operated either manually or automatically to actuate the stopping place indicators over leads 1, 2 from the supply source 12. 12 of the train lighting system. The signalling leads 1, 2 of neighbouring coaches are connected to the relays 5 over plug connections 3. When it is desired to signal the next stopping place, the member 7 of a relay 5 is operated to establish contact at contacts 8, 13 to supply operating current to the indicators on the same coach and to energize relays 5 in neighbouring coaches which in turn cause operation of the corresponding indicators and energization of relays 5 in further coaches with similar results. Each indicator comprises a band wound on rollers 23, 24, Fig. 3, and driven step by step by the electromagneticallyoperated pawl and ratchet mechanism 15, 18. When contacts 8, 13 of a relay 5 are closed, magnet 15 is energized to operate the ratchet wheel 18 and attract an armature 118 to close contacts a, b which maintain the magnet 15 energized independently of the release of member 7 of relay 5. The band is thus driven until a projection of the band opens the holding circuit of the magnet 15 at normally closed contacts disposed on the band guide. In this position the band is accurately positioned with the appropriate information disposed behind the view aperture of the indicator case. Disposed between the driving wheel 22 and the gears 25, 26 of the rollers 23, 24 is a reversing mechanism which is operated when the band reaches the end of its travel in one direction. In addition to the names of stopping places other information such as time of stoppage, addresses of hotels, &c. may be displayed on the band.

Title: Process for treating artificial fibres of regenerated zein
IPC: D06P3/06
Filed: 1955-08-08
Abstract: Regenerated zein fibres, produced from zein spinning solutions which have been treated with formaldehyde, are treated with an aqueous solution of an acid, in the absence of formaldehyde, the solution having a pH value of 0.5 to 5.5, at at least 150 DEG  F., for a time sufficient to improve the affinity of the fibre for acid wool dyes, as determined by acid wool dye exhaust tests, which are described, made before and after the treatment.  The zein fibres may be dipped in the acid solution, squeezed to 50 per cent moisture content and then steamed (100 per cent R.H.) in a standard J-box for 5-120 minutes at 150-250 DEG  F.  The dye affinity thus developed is directly proportional to acid strength and to time and temperature of steaming.  After the steam treatment the fibre is water-washed, squeezed and dried.  Acids which may be used are boric, malonic, succinic, propionic, acetic, formic, oxalic, phosphoric and sulphuric acids.  The fibres may be treated either when freshly prepared or after having been aged. Specification 817,724 and U.S.A. Specification 2,478,248 are referred to.
