Title: Method of and apparatus for degreasing bones
Inventor: LING THOMAS SYDNEY
IPC: C11B1/10
Filed: 1961-08-09
Abstract: <PICT:0965460/C4-C5/1> Crushed bones are continuously degreased in a number of stages in series by crushing and breaking the bones in each stage before passing the bones in each stage through a heat-exchanger in counterflow to water at an elevated temperature below that at which collagen in the bones would be decomposed, removing the bones from the heat-exchanger, and recirculating the water after separating the fat.  As shown, bones from crusher 10 pass to bin 11 and thence to heat-exchanger 12 in counterflow to water passing through the system; the bones pass to conveyer 14 while the liquid mixture o fat and water pass to separator 21.  The bones are conveyed through two similar further crushing (15 and 18) and extraction (16 and 19) stages, the fat from separators 21-23 being combined in tank 27. Fresh water, preferably at about 160 DEG  F., enters at 37, and water from separators 22 and 23 is in each case recycled by lines 33 and 36 to the previous extraction stage, water from separator 21 passing from the system.

Abstract: 387,050. Valve amplifying circuits. SANDERSON, W. T., Fullers, Mannings Heath, Horsham, Sussex, and BLACKBURN, R., 10, Bittacy Park Avenue, Mill Hill, London. Oct. 21, 1931, No. 29228. [Class 40 (v).] A valve amplifier for audio or radio frequencies has a low-resistance tuned circuit g, h connected in a common portion of the grid and plate circuits adjacent to the indirectlyheated cathode f, thereby sharply attenuating any signal of the frequency of the tuned circuit. As shown applied to an audio-frequency amplifier, the circuit g, h is tuned to an interfering audio-frequency such as a Morse note or a heterodyne whistle. Grid bias may be obtained from a resistance i in the common branch. For radio frequencies, the circuit g, h is tuned to an unwanted frequency, and the connection from the cathode f may be made to a variable tapping on the coil g. Several circuits such as g, h, tuned to different interfering frequencies, may be used.

Title: Removal of high melting constituents from oils
IPC: C10G73/06
Filed: 1958-09-12
Abstract: <PICT:0867824/III/1> A process for removing relatively high melting point material from oils comprises dissolving oil in a normally gaseous solvent at a temperature above the pour point of the oil charge and at a pressure sufficient to make said solvent liquid, diluting the oil-solvent solution by addition of said solvent in the liquid phase at approximately the atmospheric boiling point thereof to lower said solution to a temperature not greater than the pour point of the desired oil product, rapidly cooling the said diluted solution to reduce its temperature to a temperature sufficient for solidification of substantially the whole of said high melting point materials to provide a slurry having as a solid phase said high melting point materials in small particle form and as the liquid phase of less density the desired oil product in solution in a solvent, passing said slurry under elevated pressure through a separation zone, subjecting said slurry while in said zone to gravity multiplying forces which progressively increase in the direction of the zone outlet to progressively multiply the density difference between said solid phase and said liquid phase to promote movement of said solid phase particles away from the inlet of said zone and towards the outlet of said zone to thus displace liquid phase material and promote its movement towards the inlet of said zone, contacting said slurry in its movement through said zone with physical obstructions to facilitate separation of the liquid phase from solid phase particles, and removing the separated solid phase particles from said outlet of said zone and liquid phase material from the inlet of said zone. The specific example describes the dewaxing of a waxy lubricating oil distillate having a pour point of 100 DEG F. using liquid propane as dewaxing solvent.  Referring to Fig. 2 which represents a centrifugal separator capable of multiplying gravity effects 5,000 times, e.g. by rotation at 2,000 r.p.m. when the maximum diameter is 48 inches, the flash chilled oil-propane mixture is introduced through line 53 and enters through line 531 to a central point in the separator.  A wash charge of liquid propane is introduced through lines 68 and 69 to the periphery of the separator.  The heavier wax particles gravitate to the outer region of the separator and are removed through line 71, the annular space around line 68, and line 45.  The lighter mixture of dewaxed oil and propane pass through line 63, the annular space around line 53, and line 65.  For a more detailed description of the aparatus shown in Fig. 2 reference is made to U.S.A. Specification 2,670,132. The term "oil" is defined as including fatty acid glycerides and also the fatty acids themselves.  Another specified use of the process is the separation of stearic acid from mixtures of oleic and linoleic acids.

A chain 67 extends to a further similar locking means housed in member 52 but in which the locking means is biased towards the locked position. A spring clip 66 attached to the chain 67 serves to retain this locking means (see Fig. 4) in the open position. In use, upon the fall of the user the clip 66 is pulled from the upper locking means causing this to lock on to the cable, and the lever 37 pivots on the lower locking means against the biasing action causing this means to also lock on to the cable.

Title: A method of purifying profibrinolysin
IPC: C12N9/68
Filed: 1957-09-20
Abstract: A purified, highly-active profibrinolysin substantially free of inhibitors is obtained by suspending the profibrinolysin in aqueous acid of pH 1 to 5, separating the acid solution from the insoluble contaminating material, neutralizing the acid solution until the pH is between 6 and 8 and adding a water-soluble salt of cadmium, mercury, lead, or zinc to precipitate the profibrinolysin from the solution in the form of a metal salt. Profibrinolysin is decomposed by (a) dialysis against distilled water to remove the metal, the dialysate being lyophilized, (b) treatment with an ion-exchange resin having free acid groups, e.g. Dowed 50 (H form), followed by lysphilization of the supernatant, or (c) treatment with disodium ethylenediamine tetraacetic acid followed by dialysis and lysphilization of the dialysate.  The profibrinolysin may be obtained from human or mammalian blood such as borine blood.  Specification 840,192 is referred to.
