Abstract: 907,921. Freezing blood, bone-marrow &c. UNION CARBIDE CORPORATION. Nov. 3, 1960 [Nov. 9, 1959], No. 37764/60. Drawings to Specification. Class 29. In freezing biological suspensions of cells, e.g. blood or bone-marrow, heat is abstracted from the walls of the suspension container at a rate of at least 14,000 B.T.U. per hour per square foot of container surface. The container, made of e.g. aluminium, magnesium or stainless steel and containing but not filled with the suspension, is immersed in liquid nitrogen or other liquefied gas at atmospheric pressure. To prevent a layer of heat-insulating nitrogen gas covering the surface of the container, the latter is coated with a heat insulating layer, e.g. of petroleum jelly, which reduces the temperature difference between the container surface and the refrigerant sufficiently. Generation of refrigerant bubbles may be enhanced by applying a powder to the surface of the insulating layer. Thawing is effected by water as quickly as possible and the heat insulating layer is preferably soluble in water. The container may be shaken during freezing and thawing. Specifications 777,232 and 777,233 are referred to.

Title: Improvements in the purification of aluminate solutions
IPC: C01F7/47
Filed: 1967-08-17
Abstract: 1,207,835. Purification of aluminate solutions. UGINE KUHLMANN. 17 Aug., 1967 [18 Aug., 1966], No. 37998/67. Heading C1A. Sodium aluminate solutions produced by alkaline attack on bauxite at high temperature and pressure and containing iron both in suspension and solution are purified by contact with granular monohydrate bauxite in such conditions that the ratio between the surface area of the grains in m<SP>2</SP> and the rate of flow of the solution in m<SP>3</SP>/hr. is between 150 and 600. Soluble iron compounds are deposited, after decomposition, on the grains, together with iron from suspension. The liquid to be purified may be passed through a moving bed of bauxite grains agitated by the flow of solution, or through a fixed bed whose grain size decreases progressively, e.g. from 5 to 0.5 mm. When the bed becomes clogged by deposited iron compounds, regeneration is performed with crude aluminate solution, and should the bed become clogged with alumina because of decomposition of the aluminate solution, regeneratoin may be performed using an impoverished liquor tapped off from the outflow of the procses.

[Also in Group XXXVI] The main circuit components of an amplifier are housed in a metal box 1 whose closing plate 2 is formed with a well 13 containing the operating batteries 16, 17 which are secured to a coverplate 14 and are connected to the amplifier circuits by contacts 27, 41 and 40, 42 and by a switch 29. The latter is arranged so that in the " ON " position its operating member 48 engages the portion 51 of a member 49 pivoted on the cover 14, thus causing the portions 50 to lie over the heads of two of the fixing screws 43, 44 and so prevent removal of the cover 14. To remove the latter the head 57 of a rod 52 is rotated by a key to cause a collar 54 to turn member 49 clockwise thus opening switch 29 and allowing all the fixing-screws to be released by the key. Replacement batteries may be supplied together with a new cover, switch and interlock and both the battery and amplifier compartments are sealed. The Provisional Specification states that the arrangement of screws 44 is such that should an attempt be made to fit a replacement cover 14 with member 48 in the " ON " position, the engagement of contacts 27, 41 and 40, 42 is prevented, and that the box 1 and the battery compartment are flameproof.

Abstract: 1,089,944. Stretching filaments. ASAMEI KASEI KOGYO KABUSHIKI KAISHA. Sept. 9, 1965 [Sept. 9, 1964], No. 38551/65. Heading B5B. Apparatus for stretching synthetic fibres to obtain a yarn having a periodically varied fibre denier comprises a feed-roll 3, a snubbing pin 4, a stretching roll 5 an axially extending segment of the surface of which has an aventurine finish, the remaining, narrower, segment of the surface being mirror finished, and a separator roll 6, the whole surface of which has an aventurine finish. (See Fig. 1). In the alternative apparatus of Fig. 2, two separator rolls 6 are used. The period of denier unevenness of the fibre may be changed by changing the diameter of the stretching roll 5, and the amplitude of denier unevenness of the fibre may be increased (a) by decreasing the number of wraps around the combination of the stretching roll and separator roll as in Fig. 1, or (b) by decreasing the length of surface of the stretching roll in contact with the running yarn by employing a combination of the stretching roll and two separate rolls as in Fig. 2, or (c) by increasing the proportion of the aventurine portion of the surface of the stretching roll, and thus also increasing the proportion of the less stretched portions of the fibre. In a modified apparatus, not shown, one or both of the separator rolls 6 is replaced by a fixed snubbing pin having an aventurine surface. Examples describe the stretching of polycaprolactam filaments. The method of the invention may be used for polyamides, polyesters, polyolefins or polyacrylonitrile.

Title: Improvements in and relating to methods of manufacturing semiconductor devices
Inventor: DEAN RONALD JOHN
IPC: H01L23/498
Filed: 1965-09-13
Abstract: In the manufacture of a semi-conductor device a pattern of metal connections held in predetermined relative positions by insulating oxide is formed by a method involving partial oxidation of a metal sheet, and the treated sheet is held in position relative to contacts provided on a semi-conductor body while metal contact areas of the pattern are secured to contacts on the body. The patterned sheet is made by photo-resist masking both sides of an aluminium sheet, briefly etching the sheet in dilute caustic soda, and anodizing both sides of the sheet at room temperature with aqueous sulphuric acid containing glycerine.  A 60m  sheet may be oxidized completely in this way. In modifications the metal sheet may be masked on only one side before its anodization on both sides to leave an oxide sheet having inlaid conductors; the conductors may then be insulated except at contact areas by removing parts of the masking before completion of anodization or by selective deposition of insulating material after completion of anodization.  In a further modification one side only of the metal sheet is anodized, the remaining metallic oxide is then photo-exist masked, and exposed metal areas are etched away to leave a pattern of conductive tracks on an oxide substrate.  A suitable etch for metallic aluminium contains 50 vol. % concentrated hydrochloric acid, 1/2 vol. % wetting agent, and distilled water. Conducting parts other than connections may be left in the patterned sheets; these are trimmed off or severed in the completed semi-conductor device.
