Abstract: 667,299. Drying timber. BACHRICH, J. L., and BACHRICH PATENTS, Ltd. Sept. 18, 1950 [June 20, 1949], No. 16357/49. Class 34(ii) A timber drying kiln comprising drying chambers C superimposed upon but separated from flues or conduits for the circulation of hot gases has flues 7 of relatively poor thermal conductivity adjacent the furnace 1 and conduits 8, 11 of high thermal conductivity for the passage of gases in the ports of the kiln remote from the furnace to ensure uniform heating in the kiln. Combustion gases leave the furnace 1 through passages 3 having baffles 4, 6 which divide the gas stream, one portion passing through brick flues 7 communicating with steel conduits 8 which after several turns discharge the gases into a settling chamber 9 at the base of the chimney. From the point where baffles 6 divide the gas stream another portion flows through flue 10 and steel conduits 11 and is discharged into chamber 9, the other side of the apparatus having similar conduits 8a, 11a, passages 12, 13 and settling chamber 14. A sheet metal floor separates the heating passages from the chambers C and timber E supported on steel joists D is dried by warm air circulated by fans F and heated by radiation and convection &c. from the floor B, the moist air escaping from vents H. Steam may be supplied to the chambers from an auxiliary boiler heated by the furnace.

Title: Improvements in the manufacture of margarine, artificial cream and other emulsions, rich in fat
IPC: A23L9/20
Filed: 1930-05-28
Abstract: Milk, cream, and other aqueous liquids used in making margarine, artificial cream and other fatty emulsions is pasteurized by heating at 50-90 DEG  C., preferably 65 DEG  C., in the presence of carbon dioxide.  Increased or reduced pressure may be employed.  The liquid may be saturated with the gas when cold, a substantial amount of the gas being expelled on heating, or the gas may be added when the liquid is at pasteurizing temperature by bubbling it in, or by treating the liquid in thin layers therewith.  The liquid may be heated by passing through it hot carbon dioxide.  The gas may be removed by the aid of vacuum or heat or by passing sterilized air through the liquid.  Milk and cream for ordinary use after pasteurizing in the above manner is filled into sterilized bottles and then pasteurized in the usual way at 50-100 DEG  C.  When the pasteurized product is used for making artificial cream &c. the finished emulsion may be pasteurized in the bottles, cans, &c. in which it is enclosed.

Filed: 1919-07-02
Abstract: 158,009. Codd, T. J., and Johnson, H. July 2, 1919. Addition to 141,107. Heating by circulation of fluids; radiators; steam traps.-In the heating system described in the parent Specification, the calorifiers or steam - heated water-heaters are replaced by steam-heated radiators, rollers or the like. Steam is admitted to each radiator through a pipe a, Fig. 3, immersed in the water at the bottom of the cast iron sections, as described in Specification 163,640. The steam then passes to the top of the sections through a pipe b<1> under the control of a stop valve b<2>. Water condensed in the pipe a is led off through a thermostatically controlled trap T. A pipe b<4> is so connected to the sections and to the condense outlet as to lead off water from the sections when it rises above a certain level. The outlet valve of the trap is operated by the expansion of a rod E, Fig. 5, secured to a sliding block F, as described in Specification 166,480. A spring S, between the top of the sliding block and a screwed sleeve F<2> takes up expansion of the rod after the valve has been closed.

Filed: 1945-07-02
Abstract: 595,391. Vehicle couplings. MURRAY, W. M. July 2, 1945, No. 16826. Convention date, Jan. 31: [Class 103 (v)] A ball and socket coupling comprises a channel-section member having a base 7, adapted to be secured to the towed vehicle, and sides 8 which are extended beyond the base and joined together at the front to form a socket for the reception of a ball adapted to be secured to the towing vehicle. The ball is formed of a part-spherical member 1 and a bolt 3 having a part-spherical bead 5. The socket has a downwardly sloping wall 15, which guides the ball into place when it is inserted in the cavity at. the rear of the socket, and a semicircular lip 12, which prevents disengagement of the ball in the vertical direction. The ball is retained in thesocket by a block 19 having a concave face 20 and carried by arms 18 pivoted to lugs formed on the sides 8. A link 24, formed with a handle 36, is pivoted at 21 to the arms 18 and at 25 to the forked end of a plunger 26 having a reduced portion 29 encircled by a coil spring 35 and slidable in a pivoted guide block 30. Movement of the plunger is limited by washers 33 retained by a split pin. When the handle is in the closed position shown, the pivot 25 is below the line of the thrust of the block on the ball so that the spring 35 acts to lock the handle in the closed position. Release of the coupling is effected by raising the handle to the position of Fig. 3 (not shown). A safety pin 23, engaging holes in the sides 8, is inserted to prevent raising of the handle when the coupling is in use. Wear of the ball and socket is taken up by transferring one or more of the washers 33 from the rear to the front of the guide block 30.

Abstract: 594,387. Supporting shuttering for concrete casting. LINDEN, K. E. July 4, 1945, No. 17010. Convention date, July 4, 1944. [Class 20(ii)] [Also in Group XXX] An adjustable support for board moulds used in casting concrete roofs, ceilings and the like comprises an outer tubular column 2, mounted on a base plate 1, and an inner column 3 which can extend therefrom to support and raise the mould, a cross-beam of which is engaged by the U-shaped member 6. A rope 8 passes round a pulley 11, disposed beneath the inner column, and has one end secured to the outer column after passing through the hole 17. From the other side of the pulley the rope passes through another hole in the outer column to the drum 15. The shaft 13, on which the drum 15 is mounted, is rotatable in the casing 10 which is rigidly secured to the outer column 2. The rope can be. wound on to the drum by a crank mounted on the shaft 13, and the drum can be locked in position by a pawl 9 co-operating with a ratchet wheel 7 also mounted on the shaft 13. Disposed at the top of the column 2 and surrounding the column 3 are two jaws 4 which can be clamped about the column by two bolts 5. The column 3 is raised to the required height by winding the rope 8 on to the drum 15, and fixed by clamping the jaws 5 on to the column 3, which is then held in place because the lower edges of the jaws are supported by the outer column 2. Thus, during and after casting of the concrete, the load of the roof or the like is supported entirely by the outer rigid tubular column, and the rope is unloaded. The column 3 may be either solid or tubular, and the rope 8 may be secured directly thereto instead of passing over a pulley.
