Title: Method of tempering a glass article
IPC: C03B27/00
Filed: 1936-03-04
Abstract: 452,268. Tempering glass. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Littleton, J. T. ; 31, East 5th Street, Corning, New York, U.S.A.) March 4, 1936, No. 6560. Convention date, April 17, 1935. [Class 56] A method of tempering glass articles comprises the step of heating an article in two stages, a first stage in which the article is heated uniformly to a temperature which lies between the annealing and the softening temperatures, and the second stage in which the surface of the article is rapidly heated to a temperature near to or above the softening temperature. After the second stage, the article is chilled in any suitable way, such as by quenching it in oil or in a mixture of sodium nitrate and potassium nitrate at a temperature of 250-285 C. The process may be used for hardening an article made from borosilicate glass or from a lime glass having the composition SiO2, 72À86 per cent; Al2O3, 1À37 per cent; Na2O, 16À29 per cent ; K2O, 1À65 per cent ; CaO, 5À00 per cent ; MgO, 3À36 per cent and B2O3, 0À56 per cent.

Title: Improvements relating to power-transmission mechanisms
IPC: F16H3/00
Filed: 1952-03-13
Abstract: 730,772. Reversing-gearing. SINCLAIR, H. March 13, 1953 [March 13, 1952], No. 6570/52. Class 80(2). In a marine power plant, at least one of two or more parallel power paths, each including a controllable hydraulic or magnetic slip coupling, between the shaft 2 of a gas or steam turbine 1 and the propeller shaft 19, provides forward drive only and the other or each of the others selectively provides forward or reverse drive. Shaft 2 is geared to parallel shafts 6, 7 driving shafts 15, 16 through hydraulic couplings 8, 9 with adjustable scoop tubes for emptying and filling controlled by levers 13, 14. Shaft 15 is geared directly to shaft 19, to give forward drive only, while shaft 16 is connected to shaft 19 through reversing gearing controlled by clutches 26, 27, as described in Specification 629,725, to give' either forward or reverse drive. During normal forward running, power is transmitted through both paths, both couplings 8, 9 being full and clutches 26, 27 being set for forward drive. To change to reverse running, the coupling 9 is emptied, the turbine power is reduced, clutches 26, 27 are set for reverse, coupling 9 is again filled so that the mechanism is in a neutral condition in which the two power paths are in opposition and the two filled couplings are more or less stalled and thus provide a load which prevents undesirable overspeeding of the turbine 1, and the coupling 8 is finally emptied so that drive passes only through coupling 9. To change back temporarily to forward running, in manoeuvring, coupling 8 is filled and coupling 9 emptied, the clutches 26, 27 remaining set for reverse, so that the neutral condition is again passed through to prevent overspeeding. To return to reverse running, coupling 9 is filled and coupling 8 emptied, overspeeding being again prevented.

Filed: 1935-03-02
Abstract: 430,812. Motor driving-arrangements. BAUER GES., E., 10, Neckarstrasse, Untert³rkheim, Stuttgart, Germany. March 2, 1935, No. 6609. Convention date, March 3, 1934. [Class 35] A clutch member is caused to move into or out of the coupling position by connecting it to the motor rotor which is moved axially by the magnetic drag exerted when the stator is moved axially. In the form shown, the stator a is moved axially by the handle o and the movement of the rotor b thereby produced causes the clutch member d on the rotor shaft to engage either of the clutch members f, g. These members co-operate with means to drive the driven shaft in opposite directions, so that the driven apparatus may be rotated in either direction at will without reversing the motor. The handle o is attached to a nut p working on a threaded boss q and it moves the stator axially by means of rods t. Stops are provided to hold the clutch member d in the clutched or idle positions.

Title: Ignition systems
IPC: F02P3/08
Filed: 1971-03-12
Abstract: 1368807 Ignition systems L NELSON-JONES 29 Feb 1972 [12 March 1971] 6645/71 Heading F1B A process for charging the capacitor 11 of an ignition system comprises utilizing the stored energy in the core of a transformer 6 to charge the capacitor, the stored energy being provided by a transistor (5) switching circuit from a primary source of power and the time constants of the circuit components are of such values that the correct relative timing of the charge and discharge cycles are achieved without the use of additional timing circuits or components and the transistor switching circuit is arranged so that the flux level in the transformer is built up to an effectively constant level during each cycle of operation so that on transferring the charge stored in the transformer core 6 to the capacitor of the discharge circuit an effectively constant energy level is achieved in the value of the charge in the capacitor thus ensuring an effectively constant value of the high voltage pulse output to the ignition or spark plugs of the engine despite large variations in the voltage of the primary source of power. The discharge of the capacitor may be initiated at the same instant as or immediately following the initiation of the switch or of the flux in the transformer core and is controlled so that the flux reaches its peak value after the capacitor discharge is complete. The input triggering pulse applied to the terminals 1 may be derived from a conventional ignition contact system with additional pulse shaping components or from a magnetic or photo-electric pick up.

Title: Improvements in apparatus and method for conditioning gases
IPC: B01D53/04
Filed: 1946-03-04
Abstract: <PICT:0632643/III/1> An adsorber unit for conditioning gas has an entering surface for gas to be treated and an opposite face from which the gas emerges, an adsorbent between them, and a heater 24 embedded in the adsorbent and spaced a short distance from said opposite face and remote from the entering surface.  In operation, gas to be treated enters chambers 5, passes up through a port 14 in a shell 2, thence down a port 13 and into the body of adsorbent into a chamber 6 and then out by a discharge duct 10.  Simultaneously scavenging gas passes down a pipe 8 along a slide valve 16 to a port 13 in a second shell, upwardly through said port through a second body of adsorbent, a port 14, valve 15 and a pipe 9.  To reactivate the adsorbent in the shell that has been adsorbing, the process is reversed by moving the valves 15 and 16 to their opposite position. The situation of the heater is such that scavenging gas contacts the hottest part of the adsorbent first, whereas the gas to be conditioned contacts the coolest part first. The adsorbent material itself may function as a heat insulator or a particular material may be used, and placed between the adsorbent and the face from which the conditioned gas emerges.
