Title: Improvements relating to control means for spindle driving and elevating gear for use in connection with drilling and like machine tools
IPC: B23Q5/32
Filed: 1935-05-25
Abstract: 457,451. Drilling and like machines. ASQUITH, Ltd., W., Highroad Well Works, and JOHNSON, A., Tanfield, Westborough Drive, Highroad Well, both in Halifax. May 25, 1935, No. 15260. [Class 83 (iii)] In control means for spindle driving and elevating gear for use in connection with drilling and like machines, a single control lever operating in a gate on the tool spindle carriage controls the forward and reverse motion of the tool spindle and the elevating gear for the spindle support, means being provided whereby it is impossible for the operator to engage the elevating motion until locking mechanism for the spindle support has been put in the unlocked position. The control lever A is pivoted at a, Fig. 1, to a collar on a rotatable but axially-fixed switch shaft B, the switch contacts c, c<1>. Fig. 3, for the forward and reverse rotation of the single driving motor for driving the tool spindle and the elevating gear, are operated when the lever is moved up and down in the slots, the mid-position disengaging the contacts and stopping the drive. When the control lever is moved to the right-hand slot, Fig. 2, a rod G, Fig. 1, is moved endwise and spiral teeth at the end of the rod engage with and rotate a lever g<2>, which actuates through linkage, a clutch for engaging the elevating screw with a constantly driven shaft rotated by the driving motor. In the case of a radialarm drilling machine to which the invention is applicable, the shaft K, Fig. 2, which effects locking of the arm is connected to a latch L which engages a groove g<5> in the rod G and thus prevents the control lever A being moved into the arm elevating and lowering slot when the arm is locked. A modification of the invention is described to suit a radial drilling machine provided with a belt or other mechanical drive in which case the switch is dispensed with and the control lever connected by linkage to any suitable form of spindle reverse mechanism.

Abstract: 529,272. Weighing and mixing grain; electric signalling systems. ROBINSON & SON, Ltd., T., and SMITH, L. May 26, 1939, No. 15645. [Class 143] [Also in Group XXXV] The discharges of a group of automatic weighers forming part of grain mixing or blending apparatus are controlled by electric switches actuated by arms adjustable along parallel rods which are turned by means of pegs projecting from a constantly-rotating drum. As shown in connection with six weighers j which are caused to discharge by energization of electromagnetic catches m, a drum c with twenty rings of pegs e projecting therefrom in various numbers is constantly driven by an electric motor b. Six vertical parallel rods f (one for each weigher) each carry an arm g slidable thereon to co-operate with any one of the rings of pegs e according to the number of discharges required of the corresponding weigher per revolution of the drum. The weighers discharge into divided hoppers n from which the grain runs on to a band or worm mixing conveyer o. A pivoted flap p in each hopper division n<SP>1</SP> is coupled to a tilting mercury switch q. If the grain supply to any weigher fails, the corresponding division n' empties and the flap p rises thus opening its mercury switch and by breaking the circuit through a plug t, socket u and coil 9 trips a contactor switch z and stops the whole apparatus. The electromagnetic catches m are connected by twin flex to a plug r insertable in a socket s. In operation, the arms g are set along the rods f according to the percentage of ingredients required, and a push button 3 for closing the contactor switch z is depressed to start the motor b and drum c. When any switch h is operated by a peg e the corresponding electromagnetic catch m is energized and its weigher is discharged. When the plug t is inserted, a long leg v thereon opens the corresponding self-closing micro-switch w and substitutes a circuit through the mercury switch q. The plugs t and rare parts of a unitary structure x to ensure insertion together. Any weigher may be put out of action by removing the corresponding structure x or by sliding the corresponding arm g out of the range of the pegs e.

Title: Improvements in and relating to production of molded metallic articles
IPC: C22C33/02
Filed: 1945-06-20
Abstract: A method of making porous metal articles comprises mixing together metal powder, a hydrated metallic bonding compound, preferably a hydroxide of the metal in the form of a colloidal suspension and, if desired a volatilisable binder, moulding the resulting pasty mass to the desired shape, drying and then heating in a reducing atmosphere to reduce the hydroxide to the metal and to sinter the metal particles.  The method is described in connection with the production of porous moulds for casting metals and of porous filter elements. In one example, iron filings, all of which passed a 40 mesh screen and 90 per cent of which was retained on a 100 mesh screen was mixed with a paste comprising 30 per cent ferric hydroxide, water and ammonium chloride solution and with granulated ammonium chloride, the proportions being 80 parts iron powder, 4 parts granulated ammonium chloride and 16 parts of the paste.  The mixture had the consistency of damp moulding sand and was formed into the desired shape using ordinary foundry technique for moulding sand.  The resulting moulded shape was allowed to dry and was then heated in a hydrogen atmosphere for two hours and forty-five minutes at a temperature of 2100 DEG  F. In another example 75 per cent of iron powder all screened between 20 and 50 mesh, 15 per cent by weight of ferric hydroxide paste containing 30 per cent ferric hydroxide and 7 per cent by weight of dry ammonium chloride were mixed and moulded into discs four inches in diameter and half an inch thick. There were dried and heated in a reducing atmosphere for two and a half hours at 2000 DEG  F. to form filters which could be further treated by hot steam to partially oxidise the exposed surfaces. Instead of using hydroxide in the form of a paste added to the iron powder, the powder may be treated with acid and then with ammonium chloride so as to form a thin coating of ferric hydroxide on the granules.  The invention may also be used for the production of articles of chromium, nickel, cobalt, copper, manganese, aluminium, cadmium, magnesium, tin, zinc either alone or in admixture with each other or with iron.
