Limited-strength or vapour-permeable containers charged with liquid or gas are sterilized in an autoclave heated by steam, the pressure in the autoclave is regulated to counterbalance the container pressure, and the autoclave atmosphere is agitated for complete, sterilizing-exposure of the container. Containers are sterilized in a chamber 10, the temperature and pressure of which are regulated by the separate supply of steam and air through lines 13 and 16 respectively, the provision of a fan 12 ensuring sterilizing-exposure of the containers to the steam pressure changes during heating and cooling of the containers are duplicated by a closed variable-volume element 20 whereby a container pressure excess, resulting in an expansion of the bellows, will drive a lever arm 24 into engagement with contact 25 to admit air through the line 16, and chamber-pressure excess will drive the lever arm 24 into engagement with contact 26 to vent the chamber through line 18. After sterilization, the steam supply is closed and air alone is supplied to counterbalance the container pressure. In another embodiment, a calculated container-pressure is relied on and the air supply is regulated by the temperature instead of the pressure of the chamber atmosphere.

Abstract: 860,396. Control of motors. PEEBLES & CO. Ltd., B., and HIGGINS, L. J. April 9, 1959 [April 28, 1958], No. 11435/58. Class 38 (3). [Also in Groups XXXVI and XXXIX] A method of detecting when a moving member reaches a given point involves the use of a ferromagnetic core with a winding, the inductance of which is caused to vary by its juxtaposition with an armature at the given point, the variation of inductance being detected and used to operate a bi-stable circuit. As shown in Fig. 1, two armatures 12, attached to a door which it is necessary should be shut before coal loading is started automatically, are situated adjacent the ends of U-shaped cores 13 when the door is shut and consequently alter the impedance of windings 14 in an A.C. bridge. When the door is open the bridge is balanced with limbs 14, 15, resonant at the supply frequency. When the door is shut the bridge is thrown out of balance and provides an output over rectifier 33, 34 to the input winding 29 of an auto-self-excited transductor 21 having bias windings 25 and positive feed-back on winding 28. The transductor is bi-stable so that once triggered over winding 29 it delivers D.C. to a load 11 which initiates coal loading. If two doors are involved in the system each door may have its own bridge circuit, the outputs of which are applied to an AND or an OR gate to trigger a bi-stable transductor so that loading takes place only when either door is shut or only when both are shut or open. To this end the bridge outputs may be used to inhibit a bias which is normally applied to the transductor. The invention is said to be applicable to the landing stage control of lift gear.
