Title: Improved process for the pasteurisation, sterilisation, or similar heat treatment ofmilk and other liquids suitable for food
IPC: A23L3/16
Filed: 1926-03-08
Abstract: 259,821. Manchester, T. C. March 8, 1926. Sterilizing and preserving milk and other liquids.-In the pasteurization, sterilization, or similar heat treatment of milk, fruit juices, and other non-oily liquid foods, other than beer and aerated beverages, air is exhausted from the liquid and its container while the liquid is being agitated, an inert ron-oxidizing gas, such as carbon dioxide or nitrogen, is simultaneously or subsequently sprayed through the liquid, and finally the liquid is heated. As shown, milk from a tank 1 passes to a container 2 from which, as well as from the milk, the air is exhausted and replaced by an inert gas from a nozzle 52<1> connected to high-pressure. and low-pressure supply tanks 36, 37. Stirring is effected by paddles 12 and heating by a steam jacket 10 and a steam coil 11. The milk may subsequently pass to a vacuum pan 3, a homogenizer 5, a cooling device 6, and a closed storage tank 7, or it may be passed directly to the homogenizer, the cooling device, or the outlet pipe 51. A pump 23 and vacuum pumps 30, 31 are provided, and all parts of the apparatus are exhausted of air and filled with inert gas.
Patent GB-1347422-A (GB)
Title: Encapsulated circuit packages
IPC: H05K3/34
Filed: 1972-02-11
Abstract: The invention utilizes specially prepared legs or feet which are attached to an integrated circuit package. The legs function as electrical communication paths for the internal circuits and also function to physically support the package. The legs include a relatively thin portion and a relatively thick portion; the thin portion is bonded to the package. Since this portion is very thin, it can be attached to the package by methods which do not require the use of special soldering additives. Not only does the invention concern the use of thinned-down legs but also the method by which these legs can be obtained. These disclosed methods include chemical etching limited to areas defined by masks and also chemical etching used in conjunction with electrolytic growing.

Abstract: 557,484. Roofs for open-hearth furnaces. BRASSERT & CO., Ltd., H. A. MILES, J., and NISSIM, R. May 16, 1942, Nos. 6672 and 14405. [Class 51 (ii)] An open-hearth furnace roof is constructed to permit charging the furnace from above by providing it with one or more removable sections which may be moved longitudinally of the furnace from their closed position to their open positions so as to lie above a fixed portion of the furnace roof which may also be formed in sections. As shown in Fig. 1, each removable section 10A, 10B, constructed of refractory bricks and surrounded by a metallic frame may be lifted by a hydraulic piston and cylinder 12 through wheels 13 and chains 14 and traversed langitudinally of the furnace by a hydraulic piston and cylinder 15 until it lies above the fixed portion 10 of the roof. The roof sections may be operated by pneumatic, electric, steam or other means. Fig. 5 shows a modification in which the roof is formed of removable charging sections 10A, 10B and removable fixed sections 19, 20, 21. 22, 23. The longitudinal edges of all the sections may be provided with sand seals. The horizontal central portions of the charging sections are stepped up at 49 to engage the frame 24 which may be cooled. Sealing between the charging sections and between the charging and fixed sections of the roof may be effected by sand seals 27, Fig. 7, into which dip hinged flanges 26 on the charging sections. As shown in Fig. 8 the roof sections may be made in two parts 39A, 39B with the longitudinal central rows of bricks 37, 38 formed with abutting concave and convex surfaces respectively, the joint being covered by a flexible metal cover 40. The longitudinal outer edges of the sections are provided with concave or convex liners 43 co-operating with convex or concave portions 42 of the skewback 41 mounted on the furnace wall 47. The two sections 39A, 39B of the roof may pivot about the joint 36 and the edges 34, 35 which are provided with sand seals 45. Specifications 542,239 and 557,508 are referred to.

Stropping-apparatus.-The rollers 12, 19, of the shape indicated and provided with coverings suitable for grinding or for stropping, are geared together and driven by an electric or other motor. The maximum radius of the rollers is greater than half the distance between their centres, so that, as they rotate, the razor blade is deflected first to one side and then to the other. To allow of this, the blade-holder is formed with a flexible stem. The stem has a rocking adjustment and an adjustment to and from the rollers, being slotted to fit over a clamping-screw carried at the end of a bracket 25, which is itself clamped with provision for vertical adjustment on the face of the motor casing. The switch for closing and opening the circuit of the electric motor may be arranged to be opened automatically after a given number of revolutions of the rollers by a train of pin-wheel gearing.

Abstract: The invention comprises a steroid of the androstane or pregnane series (including the androstene or pregnene series) having a 9a -halogen substituent and an 11-keto or 11b -hydroxy substituent, e.g. a halo-steroid of the general formula: <FORM:0792223/IV (b)/1> the 4,5-position being double-bonded or saturated, wherein R is -H and R1 is -OH (or wherein R and R1 represent = O or a group which is convertible thereto by hydrolysis), wherein R11 is H and R111 is (b )-OH (or wherein R11 and R111 together represent = O, wherein X is an (a ) halogen group, and Y is -H, -OH or -O-(acyl), and wherein Z is -H or (a )-OH, and the preparation thereof by interacting an 11a -hydroxy steroid of said series with a toluene sulphonyl halide, e.g. p-toluene sulphonyl chloride or sulphonic acid, e.g. methane sulphonic acid or p-bromobenzenesulphonyl chloride, to form the corresponding 11a -sulphonyloxy derivative, heating said sulphonyloxy derivative to form the corresponding D 9-11 compound, and treating with an N-halo amide, e.g. N-bromo-acetamide in the presence of water to form the corresponding 6-halo-11b -hydroxy compound.  The conversion of the 11a -sulphonic acid ester to the corresponding D 9-11-compounds may be effected by heating with sodium acetate and acetic acid, or by treatment with sodium or potassium iodide in acetone.  Subsequently the 9a -halo-11b -hydroxy steroid may be oxidized, e.g. with chromic acid in glacial acetic acid to form a 9a -halo-11-keto steroid.  The invention also includes a process of producing a 9a -halo 17a -hydroxy corticosterone by treating a D 4-pregnene - 9b ,11b  - oxido - 3,20 - dione with a reagent of the formula HX, wherein X represents the desired 9a  - halogen substituent.

Abstract: 1,212,192. Processing dental X-ray packs. KODAK Ltd. Jan.25, 1968 [Feb.16, 1967], No. 7409/67. Heading G2A. A radiation-sensitive film such as a dental X-ray film is enclosed in a light-tight liquid-tight envelope in which it is processed. The enclosure is such that the envelope may be pierced by an injector such as a hypodermic needle, for introduction of the processing liquid, without scoring the film itself. For this purpose the envelope may have a raised blister Fig. 3 (not shown) in which the needle is inserted, or may be of the form shown at 20 in Fig. 6, in which it is heatsealed along three edges while the fourth edge presents a surface which is generally at right angles to the plane of the film. The envelope is positioned between jaws 34, 35, and the needle 33 advanced to pierce it. The envelope may be of a self-sealing material, or have a lining of such material, so that it remains liquid-tight after the needle has been withdrawn. Fig. 9 shows a scheme in which insertion of the envelope between the jaws of the holding member actuates a sensor 36 connected to the arm 37 of a micro-switch 38, so energizing a pump to force processing liquid through a conduit 40 and valve 41 to the injector needle. When the envelope is sufficiently full, it bears against a movable platform 42 which stops the pump. The envelope is then placed in an agitator unit comprising a pivoted frame 59 having upper and lower paddle members 60, 61. (See also Fig.12 not shown). A reciprocating movement is now applied to the frame 59, so that the envelope 20 is first squeezed at one end by paddle 61 Fig. 14 and then from the other end by paddle 60 Fig. 15, thus causing agitation of the liquid within the envelope.
