Title: Process and apparatus for recovering oil from whale blubber and other like materials
IPC: C11B1/16
Filed: 1931-08-17
Abstract: In a process for recovering oil from whale blubber &c. the liquid formed in each of a number of steam pressure digesters flows through separate pipes into a common separating tank maintained at the digestion pressure, and large enough to receive all the liquid products from at least one digester.  The digesters 1 . . 5 are charged with blubber &c., closed, and placed under steam pressure. The bloodwater which first separates is blown off through a pipe 25, and the liquids which subsequently separate are passed through a valve 13 into the separating <PICT:0368655/III/1> tank 14, to which steam is admitted by a pipe 15, and which is fitted with perforated baffles 16, 17 to assist in the separation of oil.  The oil is drawn from the dome 18a by a pipe 19.  Sight glasses 18, 21 are fitted in the connecting-pipe.  The level in the tank 14 is controlled by drawing off water through valves 28 or pumping in water by a pump 32.

Abstract: 167,392. Hume, G. W., and Forster, J. D. Aug. 7, 1920. Clock-work-actuated valves.-A clock-work gas controller of the kind described in Specification 10965/12 is provided with a pair of independent lift valves adapted to be opened and closed consecutively by the opposite movements of a rocking lever. The 24-hour dial c has two pairs of adjustable tappets d, d<1>, e, e<1> adapted to engage successively rollers f<1>, f<2> on a rocking lever f, which is held in one of three positions by a spring trip lever j. The valves n, m are actuated by the opposite ends of a lever o pivoted to an arm g secured to the shaft of the lever f. The valve n is heavier than the valve m so that in the intermediate position of the lever f the stem of the valve n acts as a fulcrum for the lever o and allows the end o<1> to open the valve m. Further movement of the rocking lever brings a projection o<3> on the lever into engagement with the casing and allows the end o<2> to open the valve n. In a modification in which two valves are opened and closed alternately, the arm g directly actuates one valve while the other valve is actuated by a lever pivoted to the arm g and adapted to work over a fixed fulcrum.

Title: Improvements in contour tracing apparatus
IPC: B23Q35/123
Filed: 1958-07-23
Abstract: 889,119. Electric copying machines. SENECA FALLS MACHINE CO. July 23, 1958 [May 12, 1958], No. 23700/58. Class 38 (6). An electric copy-milling machine of the template following type has provision for locking the template following stylus in a deflected position so as to determine the path along which the stylus initially approaches the template. Movement of a cutter T, Fig. 3, is controlled by X and Y axis motors 16, 15 energized by the amplified outputs of a resolver 12. A stylus 10 is carried on a crank on the rotor of resolver 12 and is biased to follow the template 20a by a torque motor 14. The effective length of the crank may be adjusted, Fig. 16 (not shown), to compensate for changes in cutter diameter. The torque motor 14 may also be controlled to rotate the resolver 12 by an amplifier K, Fig. 10, to which is fed the output of the Y axis winding of the resolver 12 so that the resolver is rotated until the Y axis output is zero. By using pre-selected outputs of both the X and Y resolver windings the resolver may be driven to any selected angle. The stylus then approaches the template at this selected angle. On contacting the template the stylus is rotated against the force of the motor 14, thereby increasing the Y axis signal to energize a relay R to change over the motor 14 from the selected signal to the normal template-following bias signal. The rate of advance of the milling cutter is automatically controlled in correspondence with its speed of rotation by controlling the energization of the resolver to correspond to the output of a tachometer generator driven by the cutter spindle, Fig. 14 (not shown).

Title: Continuous countercurrent hydrolysis of fat
IPC: C11C1/04
Filed: 1935-08-26
Abstract: <PICT:0466596/III/1> In a continuous splitting process, fat and water separately heated to 300--600 DEG  F. and under pressure sufficient to maintain the water liquid are passed in countercurrent through a vertical chamber, the water being in an excess at least equal to the weight of glycerine to be liberated and the time of contact sufficient to cause at least 95 per cent splitting.  The pressure may be 125--1600 lb. the time of contact at least 30 min., and the proportion of water suitably such as to produce a "sweet water" containing 20--50 per cent of glycerine.  Any splitting catalyst may be used, preferably mixed with the fat; oxides and soaps of zinc, calcium and magnesium are specified.  In one example, 3500 lb. of water and 7500 lb. of tallow respectively per hour are passed through deaerators 1, 2, meters 3, 4, pumps 5, 6, heaters 7, 8 connected to a boiler 9, and over thermometers 24, 25 to pipes 15, 14 by which they are distributed into an autoclave 13 maintained at 470 DEG  F. and under 600 lb. pressure.  Zinc soap, equivalent to 0,25 per cent of zinc oxide relative to fat, is passed from a vessel 10 through a pump 12 to the fat issuing from the heater 8.  The fat takes 1 hr. to pass through the autoclave, and is 99 per cent split.  The fatty acids pass through an automatic pressure control valve 23 to a tank 16 where they are flasked to atmospheric pressure, the water vapour discharging through a pipe 18 and the acids through a pipe 17; the escaping steam blankets and so protects the fatty acid from air.  The "sweet water" containing 24 per cent of glycerine passes through a discharge rate and pressure-controlling valve 22, and is flasked in a chamber 19 to atmospheric pressure, steam passing through a pipe 21, and the "sweet water" now of 32 per cent glycerine content, discharging through a pipe 20.  In the spaces in the autoclave above the pipe 15 and below the pipe 14 are water settled out from fatty acid, and fat from glycerine water respectively, the interface between the fat and water preferably being at about the level of the pipe 14 as shown by the gauge 26.  The efficiency of the process is attributed to the solution of water in the fat under the conditions. Curves showing the percentages of liquid water dissolved by fatty acids of tallow and coconut oil at different temperatures are given; means by which such a curve for any fatty acid is obtained are described; and a formula is supplied to predetermine the proportion of water to be used to obtain "sweet water" of a specified glycerine content. In the above example about 11 per cent of water is stated to be dissolved in the fat.

Abstract: 918,197. Gyroscopic apparatus. SMITH & SONS (ENGLAND) Ltd., S. Aug. 25, 1961 [July 3, 1961], No. 23938/61. Class 97 (3). [Also in Groups XIX and XXXII] in a device for damping a rotary shaft 1 having a cylindrical surface 4 spaced, by a narrow annular gap, from the partially-surrounding cylindrical surface 5 of a coaxial relatively-fixed member 2 a film of viscous liquid, e.g. silicone liquid, is confined within the annular gap by surface tension and by rings 6-9 which contact no relatively movable parts and are made of a material, e.g. polytetrafluorethylene, which is not readily wetted by the viscous liquid. The temperature coefficients of expansion of the shaft 1 and the member 2 are such that the change in dimensions of the annular gap between the surfaces 4, 5 compensates, at least in part, for any change in the viscosity of the liquid within a predetermined range of temperatures. Spraying areas of polytetrafluoroethylene on the metal may be resorted to instead of fitting the rings 6-9. Knowing the required value A of actual to critical damping factor for a given instrument the damping constant C can be determined from the equation where I = the moment of inertia about the common axis 3, Fig. 1, and K = the constant of a restraining spring. Theoreticallywhere v = the viscosity of the liquid in centistokes. r = the mean radius of the gap in inches. I = the length of the opposed surfaces of the gap. e = the absolute density of the liquid in lbs. per cubic inch; and t = the gap thickness so that, knowing C, the dimensions of the damping device and the properties of the liquid to be used can be ascertained. If, due to temperature variations, the gap thickness is reduced then the viscosity is correspondingly reduced so that, other factors remaining constant, the damping constant C tends to remain the same. As shown in Fig. 3 a rate gyroscope has the rotor 21 of an electric motor mounted about an axis 22 in a gimbal 23 which has spindles 24, 25 at its opposite ends supported respectively in bearings 27, 28 and the rotary motion of which, about an axis 26, is restrained by a torsion bar 29 joined to the spindle 25 and to an instrument casing 20. An electromagnetic pick-off with a rotor 40 and a stator 41 carried respectively by the spindle 25 and the casing 20 is provided for generating an electrical signal in known manner. The gimbal 23 carries a member 30 with an internal cylindrical surface 32 which is generated from the axis 26 and is spaced by an annular gap from the external cylindrical surface 33 of a co-operating member 39 fixed to the casing 20, the gap being filled with silicone liquid which is confined by rings 35-38 of polytetrafluorethylene.
