Title: Medical atomising inhaler
Inventor: HALL VICTOR C
IPC: A61M15/08
Filed: 1951-05-23
Abstract: 689,225. Inhalers. SHARP & DOHME, Inc. May 23, 1951, No. 12110/51. Class 81 (ii). In an atomising inhaler a mixture of liquic inhalant and air is expelled through a nozzle and the nozzle is surrounded by an annular conduit which supplies a stream of air serving tc confine the jet of medicament and to prevent it from settling on the lower surfaces of the nostril. Liquid medicament is enclosed in a container 10 which may be compressible or connected to an external air bulb. When the contents are thus subjected to pressure a supply of medicament passes up the tube 25, which extends to the bottom of the container, and air is expelled through peripheral passages to a mixing chamber 23 and nozzle 19, so that a fine mist issues therefrom. An annular conduit 15 surrounds the nozzle and communicates through ports at its lower end with the external air, so that, when air is inhaled into the nostril 14, the stream of air through the conduit 15 prevents contact of the medicament with the lower walls of the nostril.

Title: Control of catalytic operations
IPC: B01J38/00
Filed: 1936-04-29
Abstract: In effecting reactions in fluids by means of a catalyst which progressively loses its activity during the reaction, the physical conditions such as temperature, pressure, space velocity are progressively modified so as to compensate for the deterioration of the catalyst and maintain a substantially constant degree of conversion.  The conditions may be modified either continuously or in stages.  Temperature increase may be effected by feeding the reactants at a temperature higher than that of the catalyst. In an example relating to the polymerization of propylene, butylene, &c. to produce hydrocarbons in the gasoline range, the temperature (600--720 DEG  F.) and pressure (130 lb.) remain constant and the duration of contact is increased from 80 seconds to 160, 240, and finally 320 seconds.  In other examples relating to the conversion of gas oil into gasoline hydrocarbons, the temperature, pressure, or duration of contact or any combination of these may be increased.  Specifications 416,025 and 449,050, [both in Group III], are referred to.ALSO:In effecting reactions in fluids by means of a catalyst which progressively loses its activity during the reaction, the physical conditions such as temperature, pressure, space velocity are progressively modified so as to compensate for the deterioration of the catalyst and maintain a substantially constant degree of conversion.  The conditions may be modified either continuously or in stages.  Increase in temperature may be effected by passing in the reactants at a temperature above that of the catalyst so that heat accumulates in the latter.  In an example relating to the conversion of gas oil into hydrocarbons in the gasoline range the reaction commences at 775 DEG  F., and by admitting the reactants at 860 DEG C., the temperature is gradually raised to 835 DEG  F., after which heat from an outside source may be applied to raise it to 850 DEG F. Alternatively the temperature may be kept constant and the pressure raised from atmospheric to 125 lb. per sq. in., or the rate of flow may be reduced by 5--50 per cent.  In another example relating to the polymerization of propylene, butylene, &c., to produce hydrocarbons in the gasoline range the temperature (600--720 DEG  F.) and pressure (130 lb.) are maintained constant and the duration of contact is increased from 80 seconds to 160, 240, and finally 320 seconds.

Filed: 1945-05-21
Abstract: 592,334. Machinery guards. TAYLOR, A. H. May 21, 1945, No. 12697. [Class 80 (iv)] [Also in Group XXIX] A safety device for a hydraulic press ram to prevent actuation should the press guard not be in its closed position comprises a valve 2 controlling the supply of pressure liquid from a passage 3 to an outlet 4 leading to the ram cylinder. On the lower end of the stem 6 of valve 2 is a piston member 9 working in chamber 26 to which the supply and exhaust of hydraulic fluid is controlled by an inlet valve 12 and an exhaust valve 14. These valves are actuated by a lever 23 under control of an electrical solenoid (not shown) which is energised by the making of an electrical contact when the guard is in its closed position. The lever 23 is then raised to close exhaust valve 14 and open valve 12 to a supply pipe 18 so that the hydraulic fluid is passed to chamber 26 to actuate piston 9 to open the valve 2. When the solenoid is de-energised by opening the guard the chamber 26 is exhausted and the valve 2 closed by the pressure above it. A return spring 7 for the piston 9 is made of sufficient strength to overcome any back pressure during the return stroke of the ram so that the valve 2 is closed to stop the return movement of the ram also if the guard is not closed.
