Title: Improvements in or relating to method and apparatus for manufacturing fats
IPC: A23D9/02
Filed: 1953-03-10
Abstract: Vegetable or animal fats having a predetermined air content are produced by preparing a warm mixture of air and liquid fat, then beating the mixture in a cooling cylinder with cooling, and finally immediately treating the mixture in <PICT:0735734/III/1> a heated emulsion machine from the outlet of which it flows in a continuous stream.  The mixture of air and liquid fat may be prepared by heating the fat and air and forcing them into an emulsion machine such as a cross-beater mill.  The emulsion machine for treating the cooled mixture may also be a cross-beater mill.  In a suitable apparatus warm liquid fat from an inlet 1 is pumped by a pump 2 into a cross-beater mill 3 together with air from a compressor 4.  The pump 2 and compressor 4 may be coupled together so as to supply the fat and air in the same proportions. The mixture of liquid fat and air then passes into a freezing cylinder 8, cooled by cooling means 9, and is vigorously beaten by a rotating tubular shaft 13.  Blades 12 on the agitating shaft scrape off the layer of fat solidifying on the cold inner wall of the cylinder.  The cooled air-containing fat is then forced into a heated emulsion machine 14, the connecting passage 15 having the same cross-section as the cooling cylinder.  The machine 14 has a jacket 16 for warm water.  The further worked and warm fat leaves through an outlet 18.

Title: Process for purifying potable water
IPC: C02F3/06
Filed: 1931-03-04
Abstract: Potable water is freed biologically from phenolic substances by treatment with active carbon or other adsorptive material acting as a carrier for lower organisms.  Suitable organisms such as bacteria, protozoa, and infusoria may be applied to the carrier material by treating it with liquids containing nitrogen compounds to which phenol or chlorophenol has been added, or by treating it with solutions containing a phosphate and nutrient substances, such as albumin, sugar, or urea.  A culture of organisms may be prepared in such solutions, the active carbon being added to the culture and afterwards used to inoculate a filter.  The organisms may be stimulated by passing air, oxygen, or other gas, preferably heated, through the filter, either while it is in operation or after it has been shut down.  The efficiency of the filter may be maintained by passing water containing nitrogenous compounds therethrough at intervals.

Title: Improvements in Liquid Wave Transmission of Power.
Inventor: CONSTANTINESCO GOGU
IPC: F16H43/02
Filed: 1916-05-15
Abstract: 106,309. Constantinesco, G., and Haddon, W. May 15, 1916. Hydraulic transmission of power.-In the system for transmitting power by liquid wave vibrations described in Specifications 9029/13 and 12438/14, means are provided for changing the number of phases in the system. In one form, the pipe containing a vibrating liquid column is tapped at two points separated by half a wave length so that the two branch pipes contain vibrating liquid columns differing in phase by 180‹ The wave length may be divided at three points so as to obtain three vibrating columns differing in phase by 120‹. The process may be reversed and a single phase vibration produced from a number of vibrating columns. If the wave length of the vibrating column is inconveniently long, it may be produced by a combination of inertias in series and condensers in parallel. Alternatively, the pipe containing the liquid may be coiled to diminish the space occupied by it. In another alternative, a flexible india-rubber tube may be used so that the wave length itself is short. In another example of a phase transformer, a number of inertias, say nine, are arranged in the pipe line. Between each pair of inertias, branch pipes with condensers are connected, the other ends being connected to a common point. The polyphase pipes are connected to points dividing the wave length into three equal parts. In another modification, the wave length is made up by connecting a number of inertias and capacities alternately in series.

[Classes 2 (iii) and 15 (ii)] In the manufacture of azo dyes by coupling a diazo-compound of an aromatic amine which carries several negative substituents, e.g., halogen atoms, or nitro, sulphonic, carboxylic, cyanogen, carboxylic amide or sulphamide groups, with a coupling component, the coupling is effected in the presence of methyl alcohol and in the absence of water, other than that which may be formed during the operation. As diazo components are specified 2:4-dinitroaniline, 2:4-dinitro-6-halogen-, cyano- or methoxy-anilines, 2:4-dinitroaniline-6-methyl-, ethyl-, benzyl-, or phenyl-sulphones, 2:4- dinitroaniline-6-sulphamide or -dialkylsulphamides, 2:5-dinitroaniline and its substitution products, and 2:4:6:-trinitroaniline. Any coupling components may be used, particularly those which, owing to the presence of a substituted or unsubstituted amino group, lead to the production of aminoazo dyestuffs. Specified coupling components are aniline, o- or mtoluidine, p-xylidine, p-cresidine, 2:5-dioxyalkylanilines, napthtylamines, N-ethyloxyethylaniline, N-ethyloxyethyl-m-toluidine, N-dioxyethyl-m-toluidine, N-dioxyethyl-3-methyl-6- methoxyaniline, N-ethyl (or n-butyl)-oxyethyl- 3-methyl-6-methoxyaniline, N-dioxyethyl-3- acetylamino-6-methoxyaniline, 2-ethylnaphthylamine, 1-amino-5-naphthol, and alkylation products obtained by treating 1-amino-5- naphthol with epichlorhydrin. In an example, 2:4 - dinitroaniline - 6 - methylsulphone is diazotized in concentrated sulphuric acid and coupled with N-dioxyethyl-3-methyl-6-methooxyaniline in methyl alcohol solution, which may advantageously contain an acid-binding agent, e.g. magnesium carbonate or an ammonium salt.

Title: Improvements in or relating to venetian blinds
IPC: E06B9/305
Filed: 1949-03-17
Abstract: 684,756. Venetian blinds. LISLE, V. L. ORCHARD-. June 14, 1950 [March 17, 1949], No. 7323/49. Class 20(iii) In a venetian blind operating device the slats of the blind are supported on pairs of tapes 1 with the upper ends of each pair secured to opposite sides of a bar, 7, 7a, 7b, which is rockable about its axis to tilt the slats from the horizontal position to which they are normally biased by gravity and which is held in the rocked position by a locking device, the locking device being releasable by the blind raising means to permit the slats to be returned by gravity to the horizontal position at the beginning of the raising operation. The raising and lowering cords 2 secured to the bottom rail and passing over pulleys 2a may pass directly to the operator, or, as shown, may be attached to small drums supported by flanges 2c and mounted on a common axle with a large drum 3, the drums being rotated by a cord 20 wound on drum 3. Cord 20 passes between rollers 4, 4a mounted at one end of a lever 5, which is pivoted at 6 and connected at its other end to the tilting device by a cord 18. The bars 7, 7a, 7b of square section are connected by a bar 7c and each is supported by spigots 8 in bearings. A parallel bar 9 of smaller diameter is connected to bar 7 by means of tapes 10, 11, the top and bottom of tape 10 being connected to opposite sides of bars 7 and 9, and the ends of tape 11 being secured to the opposite sides of the bars to which tape 10 is connected. A drum 12, having flanges formed with notches 13, is mounted on the outer end of bar 9 and encased at 12a. One end of a lever 16 pivoted in this casing is urged by a spring 17 to normally engage the notches 13, while the other end carries a pulley 15. The ends 14a, 14b, of a cord 14 passing round drum 12 pass over pulley 15 to the operator. By pulling on one end of the cord, say 14a, lever 16 is rocked to release drum 12, which is rotated by cord 14 rotating bar 9, which rocks bar 7 to tilt the slats, and on releasing cord 14a spring 17 urges lever 16 into engagement with notches 13 to secure the slats in the tilted position. By pulling cord 14b the rotation of drum 12 and the action of gravity returns the slats to the horizontal position. When cord 20 is pulled to raise the blind, it exerts a force on the lever 5 through roller 4, so that cord 18 disengages the lever 16 from notches 13 and the slats return to the horizontal position for raising as the cord 20 is pulled farther. Alternatively, the raising and tilting control may be arranged at the same side and the lifting cord passed over a pulley fixed on the tilting brake lever.

Abstract: 809,269. Brake adjustment. GOODYEAR TIRE & RUBBER CO. March 7, 1957 [May 8, 1956], No. 7554/57. Class 103 (1). In an automatic wear adjustment device, which in Fig. 1 is shown applied to a disc brake with the friction pad 7 out of contact with the disc 5, fluid pressure supplied by pipe 16 acts behind the piston 13 and forces it outwardly carrying therewith a second piston 14 slidable inside so as to engage pad 7 with the disc 5. If the pad wear is the maximum normally allowable the sleeve 18 secured to piston 13 will be stopped by abutment with the flange 11 secured to the end of fixed stem 9. At the same time as the sleeve 18 abuts flange 11, a port 19 co-operates with bore 20 in the member 21 to allow fluid to pass to the space behind piston 14 which slides outwardly within piston 13 to complete the brake application. On release of the brake applying fluid pressure, the pistons 13 and 14 move back together under the action of spring 23 so that the clearance is readjusted. Loosening of the nut 24 enables air or liquid to be bled as necessary from the space behind piston 14. U.S.A. Specification 2,392,970 is referred to.
