Title: Improvements in or relating to the preparation of the suspensions of titanium pigments
IPC: C09K23/00
Filed: 1937-02-22
Abstract: Titanium pigments are dispersed in aliphatic alcohols with the aid of a dispersing agent comprising a polyhalide of aluminium, cerium, iron, thallium, thorium, titanium, or zirconium, aluminium chloride being the preferred agent.  The dispersing agent is preferably dissolved in the alcohol prior to or during the addition of the pigment, suitably in the proportion of 0,1-2 per cent of the alcohol. The proportion of pigment may be such that a slurry or paste is first formed which is subsequently diluted with more alcohol.  The alcohol is preferably of low molecular weight such as methyl, ethyl, or isopropyl, but higher alcohols may be used.

Title: Method of treating milk
IPC: A23C9/15
Filed: 1938-02-21
Abstract: 514,987. Treating milk. SUBMARINE SIGNAL CO. Feb. 21, 1938, No. 5403. Convention date, April 2, 1937. [Class 49] In order to produce a milk having a curdtension of soft-curd value, but in which the cream will rise upon standing, a minor portion of whole hard-curd milk is treated, as by homogenization or the action of intense compressional wave energy in accordance with the method of Specification 433,583, [Group III], so that its curd tension is reduced to a relatively low value, and the thus treated portion is then mixed with the remainder of the milk. In an example, one part of milk treated by homogenization to reduce its curd tension to about 19 grams is mixed with four parts of untreated milk with curd tension of about 40 grams, and the resultant mixture has a curd tension of about 28 grams. A substantial reduction in curd tension is obtained if the quantity of dispersed butter fat is not less than about 0.5 per cent. by weight of the total final body of milk.

Title: Improvements in lubrication systems for fluid pressure engines
IPC: F16N7/36
Filed: 1926-02-27
Abstract: 265,019. Sanders, A. F., and Lister & Co., Ltd., R. A. Feb. 27, 1926. Lubricant conveyed by mechanical means; centrifugal-action lubricating.-In a fluid-pressure engine in which each of the main bearings 2, 3, Fig. 1, are supplied with lubricant from wells 22, 6 by ring oilers 5, lubricant issuing from the inner end of the bearing 3, being assisted thereto by helical grooves 9, is caught by a centrifugal catcher 12 secured on the crank web 13 and led into a passage 14 through the crank pin. Part of the lubricant in the passage 14 reaches the crank-pin bearing 16 through a passage 15, while the surplus is thrown off by a ring 17 secured coaxially to the web 18, and is collected in an annular chamber 25, whence it passes through a hole 21 into the wall 22 of the bearing 2. Excess 'lubricant in the well 22 drains back to the well 6 through a pipe 23. The throwing ring 17 has an outwardly-placed central hole 19, and its outer periphery is provided with spaced collars 24 to prevent leakage of lubricant from the chamber 25 to the crank case. In the case of an engine having an overhung crank, as shown in Fig. 2, lubricant, caught in the catch 12 enters an axial passage 26 in the crank pin communicating by a radial passage 27 with another axial passage 28, which at one end communicates with the passage 15 leading to the crank pin bearing, and at the other end has its outlet in the throwing ring 17. Lubricant thrown from the latter is collected in an annular space 29 and drains back to the well 6 through a passage 31.

[Class 18.] In a powder-box in which a spring-controlled diaphragm can force the powder through a series of apertures when an apertured closure member is partially rotated so that the two sets of apertures register, the rotary member is in the form of a receptacle which contains the powder and in which the spring - controlled diaphragm is located. A vanity case comprises an apertured diaphragm 6 surrounded by upward and downward flanges, of which the upward one is stepped to allow the lid to form a flush joint when closed down thereon. An inverted tray, not shown, with an apertured base is pivoted at 10 to the diaphragm 6 ; and it can be rotated by a knob 14 sliding in a slot in the diaphragm 6 to cause the two sets of apertures to register, it being preferable that the two sets first register and then go out of register during the passage of the knob from one end of the slot to the other. The powder is contained in this inverted tray and is pushed upwards by a diaphragm 17 connected by a spring 16 to the removable bottom 15 of the case. The edges of the apertures in the rotary tray are preferably burred on the inner side. A puff may be contained in the upper part of the case.

Lathes.-In a cutting-off machine, the work is clamped concentrically by means of screw actuated jaws 8 within a rotating tool-carrying headstock mounted on a fixed disc 10 supported on trunnions in a pivoted frame 2. The rack operated tool-holders 4 are traversed along dovetail guides on a disc 6 by means of spur gearing 16, 16<1>, 17, 18 driven from a loose gear 15 on the hub 11 of the driving pulley 7. The latter is mounted on ball and roller bearings on the disc 10. When the pulley 7 is rotated the gear 15 is driven from a fixed gear 14 to effect a slow forward feed of the tools through a compound spur wheel 20. 20<1> carried in a fork mounted on the end of a spindle actuated by a lever 21 held in the required position by means of a stop on the disc 10. After a predetermined forward movement of the tools an adjustable stop 25 on one of the wheels 17 displaces a pin 26 carried in the pulley 10 and causes the release of the lever 21 which is thereupon moved by a spring 24 into contact with a second stop. In this position, the gear 15 is driven through a second compound wheel 30, 30<1> the gearing being so arranged that a quick return of the tools is thereby produced. After a predetermined return movement a stop 32 displaces a pin 33 to shift the lever into contact with a third stop in which position both the compound gears are disengaged and the tool slides remain stationary.
