Title: Improvements in or relating to methods of purifying oleic acid, and the purified oleic acid resulting therefrom
IPC: C11C1/10
Filed: 1947-02-12
Abstract: Oleic acid containing poly-unsaturated fatty acids is purified therefrom by heating the oleic acid at an elevated temperature and pressure in an atmosphere of high humidity for a period of time sufficient to polymerize the polyunsaturated fatty acids and then separating the latter from the purified oleic acid.  An atmosphere of steam or other moisture laden gas or a small amount of water mixed with the oleic acid may be used, particularly steam under a pressure ranging from 80 pounds per square inch to the pressure of saturated steam at the temperature used such as 300 pounds per square inch.  A temperature of 260 DEG  to 360 DEG  C. is specified. Small amounts of polymerization catalysts may be used such as lead acetate.  The purified oleic acid may be separated from the polymerized polyunsaturated acids by solvent separation or by distillation, particularly under reduced pressure.  Specification 639,551 is referred to.

An apparatus for draining sterilized surgical instruments and/or for sterilizing such instruments, comprises a chamber defined by a heat insulated casing, one or more draining or sterilizing containers located in or projecting into the said chamber and adapted, or each adapted, to receive one or more instruments to be drained or sterilized, but being accessible, for the introduction of instruments thereinto or the removal of instruments therefrom, without opening said chamber, and electric air heating means, within said chamber and so located therein as to heat the air within the chamber and surrounding the said container or containers and to cause it to circulate around the latter for heating it or them. A combined apparatus for sterilizing and draining instruments with which is associated a storage container comprises, as shown, a casing 1 and detachable lid 2 each provided with an heat-insulating jacket 5. An upstanding insulated electric air heating element 11 is supported on a pedestal 10 resting on the bottom of the casing 1 in a position spaced from the near side and centrally of the width. This is thermostatically controlled by a switch 14 fixed to the inside of the front wall of the casing. The lid 2 has two circular holes 16 (Fig 2 not shown) spaced apart, nearer the rear than the front edge of the lid, through each of which is passed a long and narrow cylindrical draining container 17 having a lid 18, heat insulated knob 19 and peripheral flange 20 for supporting the container within the chamber 15. A reticulated rest 21 for a surgical instrument 23 is positioned in the lower part of the container 17. A long narrow sterilizing container 24 having lid 28 and plate 25 adapted to fit in an aperture 26 in the lid 2, is situated centrally of the casing and in front of the draining containers 17. It may be partially filled with water or oil and is heated by heat conduction from the element 11. Annular external fins may be provided on the sterilizer 24 to facilitate heat transfer from the interior of the chamber 15 to the interior of the container 24. After sterilization the instrument is transferred to the draining container 17 and then to a storage compartment 29 secured to the front wall of the casing 1.

Abstract: 726,444. Dampers. HEATH, J. E. Feb. 19, 1953, No. 4638/53. Class 126. A device for placing in the chimney throat of a fireplace is characterized by a plate having at least one screw member extending from one edge thereof for contact with a fire brick or other surface bounding the throat whereby the device is thrust into engagement with the back and front walls of the throat such that it may be supported therein. The device comprises a sheet metal plate 1 bent as shown (Fig. 2) to provide a flap 12 for the support of the screw fixing attachment and a flap 6 for directing smoke upwards between the plate. and the upper edge portion 7 of the fireplace opening. The plate is flanged at its side edge 2 and is provided with two series of smoke escape holes 3, 4 the latter being normally closed by a slidable shutter plate 15. This plate is formed with slots 16 which interengage with studs 17 on the plate 1 and on closing the gap 9 between the fire back 8 and plate 1 the plate 15 in moving rearwardly uncovers the holes 4 thereby ensuring some communication between fire and chimney. Down draught through gaps 5 and 9 at the forward and rear edges of the device and through the holes 3 and 4 (when uncovered) is minimized by the provision of flaps 6, 21, 19, 20, respectively flap 21 being integral with the plate 15 whilst the flaps. 19, 20, are furnished by the riveting of a guard plate 18 to the plate 1. The screw attachment means, comprises a screw 10 threaded through a block 11 attached to the flap 12 and provided at one end with a turning member and at the other with a pad 13 for abutment against the fire back. The device is completed by brackets 14 secured to the plate 1 which are thrust into firm engagement with the fireplace portion 7 when the screw 10 is tightened. The screw 10 may be drill pointed instead of being provided with the pad 13. Specifications 621,002 and 628,449 are referred to.

Abstract: 1,219,923. Temperature variable resistors. GARRETT CORP. 30 Jan., 1968 [1 Feb., 1967], No. 4648/68. Heading H1K. [Also in Division G1] The mean temperature of combustion gases in the gas passage between the combustor and inlet of a gas turbine is measured by an elongated element extending transversely through regions disposed in different angular relation about the longitudinal axis of the passage and consisting of ceramic material, the resistivity of which varies with temperature, disposed between a pair of conductors. The element (22) preferably consisting of magnesia or alumina swaged between a central conductor and a concentric sheath of " Inconel " (Trade Mark), and extends around and is clipped to the entire periphery of annular combustion chamber (13). By removing bolts and sliding the plenum and combustion chamber assemblies rearwards the element can be replaced without dismantling the turbine assembly proper. Measurement of the resistance may be effected by using the element as part of a potential divider or bridge network or by measuring the voltage across it when supplied from a constant current source. If desired the ceramic in any parts of the element disposed outside the gas flow may be replaced by another ceramic material less sensitive to temperature.

Title: Improvements relating to machines for the interpretation of numerical values represented by perforated cards
Filed: 1928-02-14
Abstract: 285,437. Tauschek, G. Feb. 16, 1927, [Convention date]. Statistical apparatus. - In record-card-controlled machines the sensing mechanism, forinterpreting the perforations in the cards and for controlling the operation of a sorting device or counting mechanism, is constituted by a drum 4, Figs. 1 and 2, having radially displaceable pins 5 with lateral extensions 6 to co-operate with a segmental bar 8 having grooves 8<a>, 8<c> separated by a ledge 8<b>. The drum is mounted in front of a slotted plate 2 the slots corresponding with the perforated columns on the card 1. In operation those pins 5 which do not enter the perforations are pressed radially and are maintained in their inner position by engagement of the extensions 6 with the groove 8<c>. If the numerical value of the perforation is determined by its position in the column a device as shown in Fig. 4 is employed with the sensing mechanism to sort the cards. A card distributor 11 is operated by a cam 9 in synchronism with the feeding movement of the card in such a manner that the pin 5 operates the slide 12<a> to cause a pawl 12 to arrest the movement of a distributor at the moment it is over the appropriate pocket 10. A sorting device for cards wherein the numerical value is represented by a succession of perforations in one column is shown in Fig. 5. The projecting pins which correspond to the numerical value in their operative movement rotate a pinion 13 gearing with a rack 15 which itself operates through a segment 16 the distributor 14.
