Abstract: ABSTRACT A method for forming a disposable face mask for medical purposes to carry out the administration of gases to a patient is disclosed and which provides a relatively soft, pliant surface that readily conforms to the patient's anatomical features in a gas-tight fit.  The mask, as formed, comprises two parts; a semi-rigid cone backing to which there is affixed a cushion formed in accordance with this invention.  The cushion is produced by in-jection molding a thermoplastic compound of a predetermined hard-ness.  The thermoplastic compound is first combined with a blow-ing agent, and the mixed compound heated to break down the blow-ing agent to give off a gas, such as nitrogen.  The heated, plasticized material is then injection molded into a mold of the desired configuration.  The molding conditions, such as the vent-ing thereof, are controlled to cause formation of a small, rela-tively uniform cellular structure within the body of the finished product cushion.  The control of the conditions involved in the injection molding process enables the final cell structure to be uniform and made up of cells which exhibit excellent pliant characteristics for conforming to the anatomical features of a patient.

Abstract: ABSTRACT A breath analyser is disclosed which has a semi-conductive sensor for measuring the alcohol content of a person's breath, the breath to be analysed being drawn, by a pump, through the sensor from a collector contain-ing a sample of the breath.  To calibrate the sensor, there is used a calibrat-ing gas having a known alcohol content, this gas being stored under pressure in a cylinder.  The calibrating gas is allowed to pass under pressure through valves to a chamber having a piston therein, so as to fill the chamber with gas.  The valves are then switched so as to connect the chamber to the sensor, whereby the calibrating gas is passed through the sensor by the action of a spring on the piston.

Abstract: ABSTRACT SHUTTLECOCKS The invention relates to moulded plastics shuttlecocks and aims to provide a moulded shuttlecock that resembles a Feather shuttlecock in appearance and simulates feather shuttlecock flight properties more closely than conventional moulded shuttlecocks.  The visible effect is achieved by moulding a skirt structure having a diverging array of stems (5) and a vane area (4) at the outer part of the skirt, the vane area being a series of half leaves (7) and part half leaves (8), one attached on either side of each stem, the leaves being shaped to appear as overlapping feathers but without any actual overlap occurring.  The desired flight properties are achieved by separating each half leaf and its associated part half leaf along part of the boundary line (10) where they would otherwise appear to overlap and forming these separated portions in different planes.

Abstract: METHOD FOR CONTROLLING REGENERATOR TEMPERATURE   IN A FLUIDIZED CATALYTIC CRACKING PROCESS             (D# 74,388-C2-F) Abstract An improved method for controlling the fluidized dense catalyst phase temperature in the regeneration zone of a fluid catalytic cracking unit.  In this method, the level of the fluidized catalyst bed above the riser discharge in the reaction vessel is adjusted in response to a change detected in the temperature of the fluidized dense catalyst phase of the regeneration zone.  Adjustment of the catalyst bed level in the reaction zone affects the coke laydown on the catalyst in the reactor and, consequently, the amount of heat liberated in the regeneration zone upon combustion of the coke contained in the partially deactivated catalyst.  A reactor bed level is attained where the resulting coke laydown on the catalyst is sufficient to maintain the de-sired temperature in the fluidized dense catalyst phase.          Also, as a part of this improved method, the amount of oxygen-containing regeneration gas supplied to the regenera-tion zone is adjusted to provide sufficient oxygen to effect substantially complete combustion of the coke to carbon dioxide and to maintain the oxygen content of the flue gas at a desired level within the range of from about 1 to about 10 mol%.  Maintaining the oxygen content of the flue gas within this range provides a flue gas having a carbon mon-oxide content of from 0 to 500 ppm.  The residence time of catalyst in the regeneration zone fluidized dense catalyst phase is adjusted to provide a regenerated catalyst with a low level of residual carbon-on-regenerated-catalyst.
