Title: Improvements in or relating to baking machines particularly for wafers or like products
IPC: A21B5/02
Filed: 1947-12-23
Abstract: 639,891. Baking wafers. BUMBA, A. Dec. 23,1947, No. 33924. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 23, 1947.] [Class 28(i)] A baking machine especially for the mass production of wafers has a horizontal shaft 6 with freely swinging radial arms 5 each carrying a baking mould 4; and the moulds 4 are filled at 4<SP>111</SP> with paste while horizontal at the level of the shaft, pass down in contact with one another and are emptied at the opposite side 4<SP>1</SP> after rotation through 180 degrees. Each mould when empty is lifted by arms 9 on rotating the shaft through 90 degrees tc a vertical position, and after a short interval is lowered on to a mould just filled to close it and so as to move the block of moulds through a distance equal to the distance of one mould. The moulds are heated by gas, steam or electricity. Each mould is a segment and has an open top closed by an adjacent mould. Cam-shaped springs 16 pivoted on the moulds lock the moulds together during baking, are closed by an abutment 22 on the frame and opened at the emptying side by a dog 27 on the frame. Alternatively the moulds are locked together by electro-magnets on the sides or ends of the moulds, similarly energized by abutments on the filling side and de-energized after baking. The rocking arms 9 lifting the moulds from the emptying to the filling position are locked on the shaft 6 which has toothed segments 58 engaging toothed segments 59 on arms 60 fast on a driving shaft 61. The outer ends of the arms 9 carry spring-loaded rods 37 engaging recesses in the sides of the moulds when emptied and release them at the filling position, the springs being actuated by abutments on the frame. The arms 9 then return to pick up an emptied mould. A spring-pressed rod engages a projection on the top mould after it is filled to prevent it from rising. The arm 60 has an extension 62 engaging a driven cam 65. The paste or dough is lifted from a vessel 150 in the base through a pipe 151 by a diaphragm pump 92 actuated by an adjustable lever system pivoted to the arm 60 and having a cam 94 on the shaft 67. The paste is distributed evenly over the mould from a moving perforated tube 72 pivoted at 75 and actuated by adjustable levers 79, 83 with a cam 88 and a return spring 90. A drip container 111 is installed below the stationary position of the arm 72. Electric heating elements in cavities in the moulds are fed with current through friction con. tacts on the mould fed from segmented contact rings on the shaft 6. which is hollow to take the conducting wires extending through a central aperture in the shaft. The heating may be regulated by switching off one or more of the supply segments.

Title: Improvements in deodorizing fats
IPC: C11B3/14
Filed: 1945-12-15
Abstract: Fats and fatty oils such as menhaden, corn, cottonseed oils, lard, &c. are deodorized by subjecting them to high vacuum distillation, preferably in a molecular still by short unobstructed path technique, removing a fraction containing an appreciable amount of the odoriferous constituents of the fat and then subjecting the fat to vacuum-cum-steam deodorization in order to improve its blandness. The steam treatment may be short, preferably not over 15 minutes, the vacuum about 6-12 mm. mercury abs. pressure and the hot fat may either be passed from the high vacuum still direct to the steam still without intermediate cooling or first passed through a counter-current heat exchanger into a storage tank after leaving the high vacuum still and before entering the steam still.  It is stated that by the above process the fat is more effectively deodorized than hitherto, with less expenditure of time and heat and less loss due to hydrolysis of the fat by the steam and that the thermally unstable anti-oxidant and vitamin constituents of the fat are obtained uncontaminated and in higher yield.

Abstract: 607,314. Binaural and directional systems. PHILIPS LAMPS, Ltd. Dec. 20, 1945, No. 34495. Convention date, Nov. 27, 1940. [Class 40 (iv)] In a stereophonic transmission system in which the pick-up microphones 13, 14 are separated by a member 12 which is an effective obstruction for frequencies above, say, 600 c.p.s. or some lower frequency, only frequencies above a limit of from 1000 to 1200 are fed to the spaced loud-speakers 19, 20, the remaining frequencies being fed to a common loudspeaker 23 in an intermediate position. The absence of stereo-effect of this latter single speaker then tends to counteract the excessive stereo-effect of the higher frequency speakers which is observed on movement of the sound source parallel to the line joining the microphones 13, 14.

Title: Manufacture of linear polyureas
Inventor: INABA YANOSUKE
IPC: C08L75/02
Filed: 1958-10-29
Abstract: Linear polyureas are made by initially heating in an inert gas atmosphere an omega-aminoalkylene urea having a straight chain containing 6 to 12 carbon atoms, or a carbonate thereof, in the presence of a stabilizer comprising an an alkyl monoamide the alkyl radical of which contains 3 to 18 carbon atoms or an alkyloyl diamine the alkyl radical of which contains 3 to 18 carbon atoms, and then raising the temperature to 215 DEG  to 265 DEG  C. and continuing the heating under reduced pressure until the starting material is converted into a linear polyurea.  The starting materials may be in solution in water, phenol or m-cresol.  The preferred alkyloyl diamines are alkyloyl-alkylene diamines in which the alkylene radicals contain 6 to 12 carbon atoms.  In the Examples:- (1) to (3) omega-aminononomethylene urea is condensed in the presence of:-(1) palmitoyl nonamethylene diamine and (2) and (3) palmitic acid amide and nonamethylene diamine; whilst in Examples (4) to (6):-(4) omega-aminooctamethylene urea is condensed in the presence of palmitoyl-nonamethylene diamine; (5) omega-aminoheptamethylene urea is condensed in the presence of pelargonic acid amide and (6) omega-aminodecamethylene urea is condensed in the presence of stearic acid amide.

Title: Improvements in or relating to machines for making cases for books
IPC: B42C7/00
Filed: 1947-12-30
Abstract: 635,802. Bookbinding. AULD, W. A. H., and AULD, J. T. Dec. 30, 1947, No. 34904. [Class 16] A machine for making cases for books comprises means for feeding a plurality of separate webs of cloth through the machine and a separate assembly for operating on each web comprising a board placing unit and a backlining placing unit, the units of at least one assembly being angularly displaced, relative to the directions of travel of the respective web, through 90 degrees with respect to the units of another assembly. In this way, after a reel of cloth has been cut into suitable widths for the normal manufacture of cases, with each case extending transversely of the web, the residual narrower web can be used to make cases of the same size, extending lengthwise of the web, provided the residual web is broader than the head to tail dimension of the boards. The machine of Specification 598,899, is modified by the provision of an extension 2a of the table 2 to support the narrow web 4 and a sub-frame J<SP>1</SP> 2  supporting the angularly displaced units 5a, 6a, the backlining placing unit 6a preceding the cover placing unit 5a in the path of the web. The units 5a, 6a are driven from the units 5, 6. Each assembly is preceded by a separate corner-cutting unit, the interval between operations of the knife of the unit operating the web 4 being greater owing to the different disposition of the boards and backlining thereon. Each assembly is associated with a lateral turn-over unit 12, 12a, being a side turn-over unit in the case of the normal web 3 and a head-and-tail unit in the case of the web 4. The turn-over units are succeeded by a common guillotine unit whose two knives are staggered in accordance with the difference in web length occupied by a case. The webs 3, 4 can be run through together or in turn. Alternatively, a separate structure carrying the units 5a, 6a and the corresponding corner-cutting unit and turn-over unit and which may also carry a separate guillotine unit, may be arranged to be secured to the side of the frame 1 of an existing machine. The glueing unit 35, 36, 38 and the reel unit are extended to accommodate the increased effective width of the web. The individual units are particularly described in Specification 598,899.
