Title: Improvements in or relating to sterilizing
IPC: A23L2/46
Filed: 1961-05-18
Abstract: 982,943. Autoclaving liquids. AMERICAN STERILIZER CO. May 18, 1961 [June 7, 1960], No. 18180/61. Heading A2D. Liquids, such as solutions and suspensions, in containers are sterilized in an autoclave by steam under pressure or the saturated vapour of another liquid and after the sterilization period a fluid cooling medium, having a vapour pressure curve lower than and parallel to those of the steam or other vapour used for sterilizing and the liquid in the containers, is led into the autoclave. Steam from a source 26 is supplied through a conduit 4 to an autoclave 1 containing bottles 2 of the solution to be sterilized. Condensate and surplus steam pass out through an outlet 6 via valves 7 and 8 to a coil 13 within a pressure tank 9 containing a cooling fluid which is thereby heated, the condensate passing on to a collecting vessel 27. By means of a control and sensing device 20, valve 8 is closed and valve 47 opened when the temperature or pressure in the tank 9 is sufficiently high, and when the temperature of the contents of bottles 2 is sufficiently high valve 5 is operated to stop the flow of steam from source 26. Valve 7 is then operated to allow the cooling fluid in tank 9 to be pumped by a pump 12 via valve 5 through spray heads in the autoclave 1 and to return via valve 7 and conduit 11 to the tank 9 where it is cooled by a secondary cooling medium supplied to the coil 13 from a source 17 before being recirculated. A suitable control circuit is disclosed. A suitable cooling medium is ethyl alcohol or an ethyl alcohol/water mixture. Specification 982,944 is referred to.

Title: Improvements relating to apparatus for treating artificial silk with liquids
IPC: D01D10/04
Filed: 1930-06-19
Abstract: Apparatus for washing or other wet treatment of artificial silk cakes comprises a plurality of movable tanks each having one or more carriers on its underside arranged to receive several cakes in a pile one below another and provided with an aperture in its bottom through which liquid can flow from the tank into the interior of the pile or piles of cakes, and a guideway for the tanks which permits them to be moved in succession beneath liquid supply means delivering liquid into each tank in turn.  As shown in the drawings the cakes a are placed on a fluted rod d with a loose separator plate b between adjacent cakes.  The upper end of rod d <PICT:0357971/IV/1> <PICT:0357971/IV/2> which is cylindrical enters a circular member d1 by means of which it is secured to the bottom of the tank e and the cylindrical portion is hollow and communicates with the flutings of the rod.  A wing nut c holds the cakes in place.  The separator plates may have projections to engage the cakes and prevent them from being damaged.  If desired the cakes could be carried on flanged hollow perforated cylindrical members instead of being separated by the plates b.  Each tank is provided with supporting bars p extending transversely beneath it, one at each end.  A stand having a horizontal top serving as a guideway for the tanks is provided with an endless chain conveyer h on which the supporting bars p rest and by which the tanks e are carried from end to end of the guideway.  A loading stand in line with the guideway receives the tanks after the cakes a have been placed on the carriers and the tanks are pushed by hand from this stand on to the conveyer h.  A similar stand is provided at the other end of the guideway to receive the tanks from the conveyer.  Liquid supply pipes f, f1 provided with filter bags are placed at intervals above the guideway.  Receptacles g for receiving used liquid are placed beneath the guideway, and are provided with draining boards l arranged so that liquid falling from the cakes a after a particular tank e has passed from above a receptacle g and before it is above the next receptacle, is led back to the appropriate receptacle.  The liquids may be pumped from the receptacles g and used over again if desired.  In a modification, the conveyer is omitted, and the tanks are pushed along the guideway manually.  The tanks may in this case be provided with rollers or wheels, or the guideway may have rollers on which the tanks rest. Specifications 344,279 and 358,151 are referred to.

Apparatus for measuring torque comprises a pivoted lever system, one lever of which is arranged for receiving the load and another lever of which is connected to a standard spring balance there being a transmission from one of the levers to an indicating mechanism. A lever 25, Fig. 2, is pivotally mounted on a ball race in a housing integral with the casing 14 and is pivotally connected to another lever 31 by struts 45, 46 and clamping bolts 47, the lever 25 bearing on the strut 46, and the lever 31 bearing on both the lever 25 and the strut 45, the bearing surfaces being the tips of conical fulcrums, Fig. 3. One end of the lever 31 is pivotally mounted in the casing by means of conical fulcrums 36, Fig. 5, carried by a plate 32 joined to the lever 31 and bearing on a rod 41 and the casing, the plate 32 being positioned by a strut 44, and the other end is fixed to a standard spring 58, the other end of the spring being adjustably held to the casing by a rod 60. The torque to be measured is applied anticlockwise with reference to Fig. 2 to a socket member integral with lever 25, and causes lever 31 to rotate about its fulcrum 36 against the tension of the standard spring. This movement of lever 31 is transmitted by means of a bifurcated lever 80 to a link 74, thence to a lever 65 pivoted to the case at 67, and finally to a rack member 63 which engages with a pinion 64 attached to the indicator needle. Light springs to limit backlash in the transmission are fitted and the position of link 74 on lever 65 is adjustable by means of a saddle piece 70 engaged to the screw 71.

Title: Improvements in or relating to activation of aluminium
IPC: C23G5/00
Filed: 1956-06-18
Abstract: Aluminium to be used in the preparation of organic and organometallic compounds is activated by heating in the presence of a compound of formula R2AlY, where R is hydrogen or an alkyl or aryl radical and Y is an alkyl or aryl radical at a temperature of at least 150 DEG  C. preferably for at least 1/2 hour.  The heating may be carried out in the presence of hydrogen and/or in an inert liquid such as heptane, cyclohexane or benzene. Specified activators include triisobutyl-, triethyl-, tripropyl-, tripentyl-, trihexyl-, triheptyl- and tridecyl aluminium; diethyl-, dipropyl-, dioctyl-, didecyl-, monoethyl-, monopropyl-, monopentyl-, mono-octyl- and mono-decyl aluminium hydrides as well as triphenyl- and trinaphthyl-aluminiums.  The aluminium is preferably comminuted by grinding, milling, drilling or like operation.  A minimum amount of activator of 5-10 per cent based on the amount of aluminium may be used.  The activated aluminium may be isolated and stored in nitrogen or under oxygen-free hexane, or more conveniently it may be reacted without prior isolation with an olefin and hydrogen to give an aluminium alkyl or an alkyl aluminium hydride.  It may also be reacted with carbon tetrachloride to give hexachlorethane.  In an example aluminium chips are heated under pressure with hydrogen and triiso butyl aluminium at 150 DEG  C. Additional hydrogen and isobutylene are then added and the system further heated to give triisobutyl-aluminium.  Example 8 describes the preparation of hexachlorethane from carbon tetrachloride and aluminium drillings activated by heating with triisobutylaluminium. Specifications 808,706 and 808,707 are referred to.
