Patent GB-485720-A (GB)
Title: A process and apparatus for dehydrating water-and oil-containing materials
IPC: C11B1/02
Filed: 1937-08-31
Abstract: <PICT:0485720/III/1> In a modification of the process of the parent Specification, particularly as applied to carcasses of animals, the comminuted material is heated for a short time at an elevated temperature in a pre-heated water bath, to which precipitating agents, for example salts, such as common salt or sodium sulphate have been added, and the pre-heated material is thereafter heated in the water bath to a temperature about 130 DEG  C. to effect sterilization, and after the separated fat has been removed the boiling water is pressed through the deposited solid materials, which are subsequently pressed and dried.  In the arrangement shown, carcasses which have been comminuted in a machine 13, pass into a boiler 2 containing water heated approximately to boiling point. Albumen-precipitatin and emulsion-preventing substances, e.g. common salt have been added to the water, so that when the carcass material is introduced quantities of water and fat separate out therefrom. After the material has been subjected to hot water treatment for a short time, the boiler is closed and heated by means of a steam jacket, so that the water under pressure rises to a temperature of about 130 DEG  C. this temperature being maintained for about 30 minutes to effect sterilization. The material is moved by stirrers 6, 7, between which is a sieve 9.  The pressure is then released, the stirrers are stopped and the mass remains at rest for a few minutes, during which time the separated fat rises to the top of the water. Boiling water is then admitted from a reservoir 15 through a pipe 11 whereby the level of water in the boiler rises until the fat overflows into pipe 12 leading to the centrifuge 14.  The water from the centrifuge is recirculated through the boiler until no more fat is collected in the centrifuge.  Specification 458,975, [Group II], is referred to.

Title: An improved scale and indicating means for use in connection therewith
IPC: H03J1/04
Filed: 1937-09-06
Abstract: 501,762. Adjusting wireless apparatus. IRVINE, K. S. Sept. 6, 1937, Nos. 24274 and 24276. Convention dates, Sept. 9, 1936 and June 11, 1937. [Class 37] [Also in Group XIX] A scale and indicating means for use in connection therewith comprises a scale having a course plotted in a spiral or helical manner, calibrations or like markings following the spiral, and a course or courses having calibrations and arranged radially outside and/or inside the first-mentioned course, and an indicator adapted to indicate against any one of the courses and its calibrations or markings, for as example the different wave length readings on a wireless receiver. Manual rotation of a spindle 22, Fig. 2, is transmitted by a belt 3b to spindle 3 loosely mounted upon which is a grooved drum 18 and a disc 12, Fig. 3, having an arcuate slit 13, while a similar disc 1 with slit 2 is keyed to the spindle 3. A chain 10 passes round the drum 18, round a pulley 9 fixed to the disc 1 and is anchored to the disc 12. During rotation of the spindle 3, therefore, relative motion takes place between the discs 1 and 12 against the action of a spring 8 and causes a spot of light formed by the aperture 21 to follow a spiral course marked upon the scale ground 5. Moreover, by tightening the chain 10 a given amount, the spot of light can be changed to follow an adjacent spiral. In a modification, the slits 2, 13 are cut away to form a leaf-shaped aperture. In another modification, one disc 26, Fig. 5, is used, a radial slit 25 therein being traversed by a shutter 28 against the action of springs 29. In yet another modification, a radially slit member is stationary whilst a disc bearing the spiral scales is rotated; in this case the aperture may be formed in a strip of celluloid which passes over a pulley adjacent the top of the slit.
