Filed: 1926-06-19
Abstract: 255,040. Grigas, J. July 8, 1925, [Convention date]. Thermal switches; contacts. - A switch for controlling the temperature of electric irons &c. comprises a bimetallic strip 23 carrying at its free end a contact 22 adapted to engage the end of a contact strip 27 mounted on an adjustable collar 29.

Title: Jaw type crushers
IPC: B02C1/04
Filed: 1948-06-10
Abstract: 643,942. Jaw crushers. TRAYLOR, S. W. June 10, 1948, No. 15651. Convention date, April 14. [Class 59] A jaw type crusher has a frame structure, a normally fixed jaws supported by said frame, a movable jaw disposed for co-operation with the fixed jaw and defining therebetween a crushing chamber, said movable jaw being pivoted at one end for movement toward and away from the fixed jaw, means for imparting oscillatory movement to said movable jaw connected to the other end thereof, and co-operatively arranged crushing surfaces on said jaws providing laterally directed discharge openings at opposite sides of the crushing chamber intermediate the pivot and drive connections of the movable jaw, said crushing surfaces on said jaws being constructed to provide at the drive end portion of the crushing chamber discharge openings of substantial size between the jaws both laterally and endwise of the chamber and diverging surface portions in the pivot end portion thereof to provide an enlarged inlet opening endwise to the chamber. A normally fixed crushing member 35, 37 is carried by a subframe 5 adapted, in certain circumstances, to pivot about a shaft 7 of a main frame 2, 4. A movable crushing jaw 36, 38 is mounted on a frame 16 pivoted on a shaft 18 of the main frame 2. Lugs 19 extending from the discharge end of the frame 16 are journalled on a transverse shaft 21 carried by a pitman 23 reciprocated by an eccentric 25 on a driven shaft 26 journalled in the subframe 5. The sub-frame 5 is normally held fixed against the main frame by springs 40 but when an uncrushable passes between the crushing jaws, the jaws open a little causing the sub-frame 5 to pivot about the shaft 7, dashpot mechanism 48 (not shown) delaying its return. The crushing jaws are shaped, Fig. 10, with primary crushing parts 35, 36 converging from the inlet to the discharge ends and secondary side crushing parts 37, 38 inclined thereto and diverging from the inlet to the discharge ends, the arrangement being such that material is discharged laterally of the crushing chamber as well as longitudinally from its discharge end. Shims 19a between the lugs 19 of the movable jaw frame 16 and the shaft 21 adjust the distance between the jaws. In a simplified form of crusher, Fig. 13, (not shown), the upper jaw is capable of no pivotal movement, being fixed to the main frame.
Patent GB-571815-A (GB)
Title: Improvements in or relating to maximum demand meters
IPC: G01R11/60
Filed: 1942-11-06
Abstract: 571,815. Maximum demand meters. LANDIS & GYR SOC. ANON. Nov. 6, 1942, No. 15692. Convention date, Nov. 20, 1941. [Class 106 (i)] A maximum demands motor comprises a maximum pointer which is advanced to indicate the maximum demand during any one of a number of short periods, a time-controlled device which automatically returns the maximum pointer to its zero position at the expiration of a number of said short periods, and a printing mechanism which prints the value of the corresponding maximum position of the pointer. As shown, the disc 1 of an electric meter drives a total consumption counting mechanism 2 which operates a driver 4 which carries the maximum pointer 7 forward to rotate a sun-wheel 20 while another sunwheel 21 operatively connected to the type wheels 18 is held stationary. Consequently, a planet-wheel 23 and a cam 24 rotate counterclockwise to close contacts 25, 26 to energize a magnet 27 which causes the engagement of a gear 30 with gear 37, driven by a synchronous motor 3. Therefore, as soon as the driver 4 advances the pointer 7, the motor 3 drives the gear 30 and a shaft 28 to advance the type wheels 18 according to the movement of the pointer 7. The shaft 28 also drives the sunwheel 21 so that, when at the end of each short period, e.g. 15 minutes, the driver 4 is returned by the motor 3 to original position; the cam 24 turns clockwise until an abutment 24b on the cam engages and opens the contacts 25, 26. The pointer 7 is held frictionally to indicate the maximum reached in any of the short periods. At the end of a month, a magnet 40 is energized to operate a hammer 19 pressing a strip 17 against the type wheels. A driver 12 is then actuated by the motor 3 through gearing 11 to return the maximum pointer to zero, and the abutment 24b engages the contact 25 to halt the planet-wheel 23, so that both sun-wheels rotate to set the type wheels to zero. The gearing 11 also advances the paper 17 and the usual date wheel through pawl-and-ratchet mechanism. The paper may be only a short length, the lower end being looped over a rod 38 in a vertical guide. Modifications.-A ratchet wheel between the differential 20, 21 and the type wheels causes the type wheels to add the maxima instead of being reset. The synchronous motor 3 may be replaced by a clock or by a calendar clock taking into consideration the number of days in a month. The mechanism 2 may be separated from the rest of the device and send impulses to the maximum indicator. The strip may be replaced by a drum or disc. The numerals of the printing mechanism may be printed on or impressed into the strip, which may consist of the substance known under the Registered Trade Mark of Plexiglass, suitably coated or of a celluloid film. The paper strip may have a wax or carbon coating.

The thrust of the screw is exercised against a spring 4 which acts on a portion 3 of the limb 2 about the pivot 10 in a manner tending to urge the limbs together and the portion 3. of the limb 2 has an edge 9 which co-operates with the spring 4 in a snap action to hold the movable limb 2 when in the fully opened-out position.

Hydrogen sulphide is removed from gases containing the same by washing with a liquor comprising (a) an aqueous solution or suspension of a compound or compounds of zinc or copper which is or are capable of reacting irreversibly with hydrogen sulphide, and (b) a soluble organic substance or substances capable of inducing reaction between zinc or copper present in the solution and hydrogen sulphide to form insoluble zinc or copper compounds and also capable of bringing or keeping in solution all or part of the unreacted zinc or copper compounds. Organic substance or substances is/ are defined as those possessing the following three properties: (1) when they are dissolved in simple aqueous solution or aqueous alkaline solution, the solution contains proton acceptor beset in addition to the water molecules and hydroxyl ions present, (2) their presence in solution increases the solubility of the oxides, hydroxides, and carbonates of zinc and/or copper in both aqueous and aqueous alkaline solution, forming complex ions or other soluble compounds which may themselves be proton acceptor bases, and (3) their presence in the reagents and the resulting enhanced concentration of dissolved zinc or copper compounds causes a reduced resistance in the liquid phase to the absorption of hydrogen sulphide. Specified organic substances are glycine, alanine, glutamic acid, aminophenols, ethanolamines, pyridine, thioglycollic acid, acetylacetone, citric acid, oxalic acid, malonic acid, urea and ethylenediamine.

Abstract: 585,674. Bending and coiling wires or strips for electric discharge devices &c. HOLMAN, H. E. July 11, 1944, No. 16041/45. Divided out of 13285/44. [Classes 83 (ii) and 83 (iv)] In shaping elements from wires or strips of tungsten or other springy metal, such as coiled wire heating elements for the cathodes of cathode-ray tubes or wound grids for electric discharge devices, the wire &c. is first provided with an electrolytic or other coating of a more ductile metal, such as copper or silver, of such thickness that when the wire &c. is shaped the element retains its shape without spring- ing apart. The element after formation is annealed and the coating finally removed by dissolving it in a suitable bath. In making coiled heaters for cathodes, a tungsten wire about 5-thousandths of an inch in diameter is coated with copper so that the plated wire has a diameter of about 20-thousandths of an inch. The wire is formed into a loop and the looped end wound round a mandrel to form a non- inductive winding and the adjacent turns pressed into contact with each other. After winding, the coil is annealed by heating in hydrogen, and after removal of the coating by dissolving in nitric acid it is again heated in hydrogen to clean the wire. The coil may be subsequently sprayed with insulation such as aluminium oxide which may be sintered at 1350‹ C. Specification 22331/13, [Class 83 (iv)], is referred to.
