Title: Improvements in or relating to air heating apparatus
IPC: F23M20/00
Filed: 1955-05-26
Abstract: 769,776. Air-heating stoves. AKTIEBOLAGET BAHCO. May 26, 1955 [May 26, 1954; March 9, 1955], No. 15289/55. Class 64(1) In an air heater in which the air is impelled by a fan 5 between a heatinsulated outer casing 2 and a longitudinally corrugated inner casing 3, the interior of the latter is divided into a combustion chamber 9 and a h e a t exchange chamber 15 by a transverse partition 11 of such size that the hot gases must pass through the corrugations.

Patent GB-863151-A (GB)
Title: Improvements in or relating to methods of blending butter
Inventor: BERG JORSTEN
IPC: A23C15/12
Filed: 1956-05-16
Abstract: Butter is blended by thoroughly mixing different grades of molten butter, adjusting the water and salt content of the mixture if necessary, and solidifying the molten mixture by chilling, e.g. in a scraped surface heat exchanger, thereafter bringing it to the consistency of natural butter by kneading the mixture and then resting it; alternatively the mixture may be rested and then kneaded. The product may then be machine packaged.  The process is conveniently effected by feeding several grades of solid butter, which may include dehydrated butter, into at least one melting tank, e.g. a jacketed tank having a tubular support grid for the butter, and bringing the butter to a temperature within the range of resolidification temperature to approximately 100 DEG F. by passing hot water through the jacket and support grid tubes. The molten mixture is then passed to a heated mixing tank, to which water, salt and colouring may be added if desired, and thence via a heated balancing tank, having flow control means to ensure an even flow, to a chiller supplied with a counter current of refrigerant, e.g. ammonia, in its outer jacket whereby the butter is rapidly reduced from approximately 100 DEG F. to approximately 48 DEG F.  The butter mixture is then kneaded, before or after a resting stage, preferably by passing it between a rotor with projecting beaters which is rotated within a surrounding stator equipped with inwardly projecting arms, and is thereafter passed into storage chambers, e.g. of the type described in Specification 773,340, before entering packaging machines.

Abstract: 168,672. Veglio, S. June 7, 1920. Spring wheels with continuous outer rigid ring and pneumatic, rubber-ring, and like cushions.- A spring wheel comprises an outer rigid ring e, Fig. 1, spaced from a hub-carried member d by a pneumatic or solid tyre. The member d may be of the cross-section shown in Fig. 2, or it may be formed integral with the tyre-carrying rim. The ring e is of the form shown in Fig. 2. The members d and e are provided with rollers g and f respectively, over which a cord or wire is led to form a driving connection as shown in Fig. 1. Two such cords may be used on each side of the wheel, and anchored to either member d, e. In order that the wheel may be used after deflation, the tyre may be provided with circumferential flanges q. The ring e may be guided by annular or segmental plates m, Fig. 1. A ring n may be secured to the plates m and contain rows of bearing balls which make contact with either member d or e. The inner edges of the plates m may have projections through which bolts s may pass. An anti-skid device may be used in the recesses t of the member e and may comprise a leather or like band having studs with heads inside the band and a lining between the heads and the member e.

Title: Apparatus for coupling railway vehicles having automatic coupling with vehicles provided with a screw coupling
IPC: B61G5/04
Filed: 1933-05-26
Abstract: 400,130. Railway-vehicle couplings. SKODA WORKS, PLZEN, 37N, Jungmannova, Prague. May 26, 1933, No. 15320. Convention date, May 27, 1932. Addition to 389,656. [Class 103 (v).] In a transition coupling-arrangement as claimed in the parent Specification, the auxiliary coupling 3 that is adapted to couple with the non-automatic hook 4 is linked to the ultimate coupler 1 by means of a separate pivoted member 2 which is so constructed that, in being swung to its operative position, it connects with the head of the ultimate coupler in the same manner as would the head of an opposed ultimate coupler. In the construction shown the intermediate member 2 swings about a vertical axis 10, while the auxiliary coupling 3 hinges about an horizontal pin 5 on the member 2 and in its operative position is supported by the abutment of a spring pin 7 against the claw 8 of the automatic coupling 1. The claw 11 of the member 2 is retained in engagement with the claw 8 by means of a vertical dropping pin 17 which, when raised, permits the member 2 to be swung aside to an inoperative position and the auxiliary coupling 3 to drop into a vertical position. The auxiliary coupling itself comprises a pair of pivoted fingers 12 that are adapted to engage the hook 4 when the latter buffs against lugs 16 integral with the fingers, a bifurcated pivoted pawl 13 dropping into engagement with the outer sides of the fingers 12 to hold them in the coupling position. The auxiliary coupling is released by lifting the pawl 13 through a pull on a chain 9, this chain, in a modification, being also effective in raising and maintaining the auxiliary coupling in its operative position. In order to prevent damage to the parts in case an ultimate coupler should be allowed accidentally to buff against an auxiliary coupling hanging in a vertical position, a flat buffing face may be furnished at a convenient part of the auxiliary coupling.

Abstract: 1453235 Purifying hydrocarbons PETROLCHEMISCHES KOMBINAT SCHWEDT VEB 8 April 1974 [30 May 1973] 15402/74 Heading C5E Hydrocarbons which have been treated microbiologically or with enzymes are purified by liquid-liquid extraction using aqueous H 3 PO 4  as the extraction agent. In examples, hydrocarbon fractions from the fermentation of 240-360‹ C. fractions are treated with aqueous H 3 PO 4  and then washed with water or ammonia water. The aqueous H 3 PO 4  and/or the water or ammonia water can be passed to the fermentation process as sources of phosphorus, carbon and nitrogen and/or to regulate the pH. A surfactant, e.g. an ethylene oxide-propylene concentrate, can be used to improve separation during the extraction.

Abstract: 1,145,122. Field-effect transistors. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 7 April, 1966, No. 15611/66. Heading H1K. A junction-gate field-effect transistor having diffused source, channel and drain regions of one conductivity type and a diffused gate region of the opposite conductivity type is manufactured with the aid of a "retardation diffusion " process in which the diffusion of a relatively fast-diffusing impurity characteristic of one conductivity type is retarded by the presence of a relatively slow-diffusing impurity characteristic of the opposite conductivity type. As shown, Fig. 4, an N+ gate region 5 is formed by diffusion of a donor into a first selected area of one face of an N-type silicon wafer, and an acceptor is then diffused into a larger area containing the first in order to. form the source 3, drain 2 and channel 4 regions, the high concentration of the donor in gate region 5 retarding the diffusion of the acceptor so that the buried channel region 4 is of higher resistivity than the source and drain regions and extends less deeply into the wafer. The remaining N- type region 1 forms a second gate region. The device may be etched to mesa configuration, Fig. 4, or may be of planar form (Fig. 6).
