Title: Improvements in bar-loading and withdrawing devices for automatic lathes
IPC: B23B13/00
Filed: 1958-10-24
Abstract: 844,138. Lathe-details. MANUFACTURE DE MACHINES DU HAUT-RHIN S.A. Oct. 24, 1958 [Feb. 10, 1958], No. 34162/58. Addition to 812,857. Class 83 (3). The mechanism as claimed in the parent Specification for loading bar-stock automatically into single-spindle automatic lathes is modified in order to withdraw the bar-stock. The connecting rods 22 have additional holes 34B for alternative location of the pins 20, and the member 13 has additional holes 24A for alternative location of the pins 24. To withdraw the bar 2, the rods 22 are in the position as shown in Fig. 5, and the member 12 is moved to the right until support member 13 is contacted and the rollers 26 enter recesses 27, thus releasing the clamps 30. The member 12 is then moved to the left, the rollers 26 leave the recesses 27, and the clamps 30 grip the bar 2. Further movement to the left of members 12, 13 withdraws the bar 2 from the lathespindle.

Abstract: 927,481. Thermometers. AMP Inc. Oct. 12, 1960 [Oct. 26, 1959], No. 34891/60. Addition to 866,528. Drawings to Specification. Class 97 (3). [Also in Group XXXVI] A tin salt of 4-methyl-1,2-dimercaptobenzene dispersed in a suitable carrier lacquer is used as a temperature change detector for electrical modular units. A narrow strip or coating of the tin salt, which exhibits a reversible colour variation is first applied to an exposed surface of an electrical modular unit (see Group XXXVI) during its factory pre-testing. While the unit is running satisfactorily at its operating temperature the colour assumed by the temperaturesensitive material is noted and adjacent to it a second strip or coating of a temperatureinsensitive material such as a paint or dye is then applied, the colour of the latter matching the observed colour of the temperature-sensitive material. Thus any deviation between the colours of the two strips during operation of the unit is an indication of temperature change of the unit. Specifications 927,483, 927,484 and 927,485 also are referred to.

Title: Improvements in the manufacture of water-soluble cellulose ethers
Inventor: BILLING JOSEPH
IPC: C08B11/20
Filed: 1954-12-02
Abstract: An aqueous solution of a cellulose ether, which is soluble in cold water but not in hot, is simultaneously mixed and heated to a temperature above the coagulation temperature of the ether, the water which separates as a liquid phase is removed, and the heating and mixing are continued under conditions such that water is evaporated from the mixture at least until a crumb-like product containing at most 60 per cent of water has been formed.  This product may then be further dried without mixing and ground to a powder, or it may be further mixed and dried until it falls to a powder.  This final powder contains about 8-15 per cent water, is non-fibrous, and is rapidly soluble in cold water.  The process is particularly suitable for methyl cellulose with a viscosity, measured as a 2 per cent solution at 20 DEG  C., above 350 centipoises, but may also be employed with methyl ethyl celluloses, methylhydroxyethyl celluloses and ethyl hydroxyethyl celluloses.  Specification 149,320, [Class 2 (ii)], is referred to.

In a continuous process for cooking rice, raw rice is fed from a hopper 6 to form a layer, e.g. about 10 cm. thick, on a travelling endless belt 1 partly submerged in water 3. The rice is carried on the submerged part AB of the belt, e.g. for 10 to 15 minutes, and on the unsubmerged part BC, e.g. for 20 to 30 minutes, to allow the rice to absorb some water and excess water to drain away. The layer of soaked rice, e.g. containing 20 to 25 per cent by weight of water, is carried on the belt through a chamber 11, wherein it is cooked, e.g. for 10 to 15 minutes in live steam at atmospheric pressure, and then through a chamber 15, wherein the undisturbed layer of cooked rice is partially dried in hot air, e.g. at 90‹C. for 15 to 20 minutes. The partially dried rice, e.g. containing 18 to 20 per cent of water, passes from the belt 1 into apparatus 24, wherein the mass of rice is reduced to individual grains between teeth 27 on a rotating cylinder 26 and a flexible strap 25.
