Title: Improvements in or relating to the extraction of gelatin
IPC: C09H3/00
Filed: 1952-06-05
Abstract: In extracting gelatine from stock such as ossein and skins of pigs, buffalo, camels, calves and rabbits, the stock is acidified, e.g. with hydrochloric, sulphuric, sulphurous, phosphoric or acetic acid, and circulated with hot water through an extractor to yield a solution of extracted gelatine having a pH of about 1.5 to 3.5 which is then neutralized to a minimum pH of about 4.0, preferably to a value of about 5.0 to 8.0.  Neutralization is preferably effected by adding caustic soda, caustic potash, sodium carbonate or sodium bicarbonate.  Salts may be removed from the neutralized solution by ion-exchange resins.  The solution may then be filtered, set by cooling, cut into slabs, dried and powdered.  Salts may be removed from slabs by dialysis.  The flow of hot water in the extractor may be either counter current to, or concurrent with, the flow of stock. The temperature of the hot water may range from about 120 to 200 DEG F. but a temperature between about 145 and 170 DEG F. is preferred. The hot water may be passed through the extractor at a rate sufficient to ensure that the extraction period does not exceed two hours.

Title: Improvements in or relating to controllers for maintaining a predetermined relationship between two variable conditions
IPC: G05D11/13
Filed: 1947-06-05
Abstract: 634,800. Automatic pressure controi systems. FISCHER & PORTER CO. June 5, 1947, No. 14896. Convention date, Sept. 25, 1945. [Class 38 (iv)] [Also in Groups XXIX and XXXVIII] A controller for maintaining a predetermined relationship between two variable conditions comprises a case, a pair of aligned shafts 34, 35, Fig. 7, rotatably mounted therein, a pair of balance beams 31, Fig. 8, pivotally mounted upon the aligned shafts, means for independently tilting the beams responsive to variations in the two variable conditions, a crankarm 46 or 47 carried by each shaft, a link 50 pivotally supported at its ends by the free ends of the crank arms so that tilting of the beams causes tilting of the link, and means actuated by tilting of the link for varying one of the variable conditions. The invention is shown applied to controlling the ratio between the flow in two lines 10, 11, Fig. 1, which are connected to a common line at 12. The flows in the lines 10, 11 are measured by flow-meters 18 and the indications of the meters are transmitted to the controller 15, and the latter applies a pneumatic pressure to a diaphragm-motor operated valve 16 in one line to correct for variations in the ratio of the flows in the two lines.. Each flow-meter includes a floating disc 21, Fig. 8, which takes up a position corresponding to the volume of flow and so actuates an armature 28 moving in coils 23, 24 forming part of an impedance bridge 23 ... 26. Any unbalance in the bridge caused by movement of armature 28 is corrected by corresponding movements of armatures 29, 30 attached to one of the beams 31, and the ensuing movement of the beam will tilt link 50. The latter is connected by a link 54, Fig. 2, lever 76, and link 79 or 79a to a bell-crank 81 provided with an abutment 100 acting on a hinged bleed valve 102, and this valve forms part of a further valve 84 described in Specification 618,228, [Group XXIX]. Valve 84 provides the pressure which is applied to the diaphragm motor of valve 16 to give the correcting action. Adjustment of the ratio of flow to which the controller is set is effected by altering the position of attachment of link 54 along link 50. This is done by means of a knob 57 which, through a pinion 58a, rack 62, and a link 68, slides a bridge 52 to which the end of link 54 is connected along a slot in the link 50. Specification 610,708 also is referred to.

[Class 135] For regulating steam generators with pressure firing by the method of the parent Specification the electric motor for driving the air compressor is according to the present invention, replaced by a steam turbine 7 which is regulated by the same means that regulate the fuel supply. To transmit the regulating forces oil, which is delivered by a pump 8, is kept at a definite pressure by a regulating valve 9 and throttled by devices 10, 10a to a pressure suitable for actuating a regulator 11, a fuel adjuster 12 and a controlling sleeve 13 by which the opening of the admission valve 28 to the turbine is determined. Any variation in the steam pressure of the generator 2 is transmitted through a piston or bellows to an outflow valve 15 in an oil pressure-line any variation of the pressure in which is transmitted to the piston 17 that actuates the fuel supply valve of the burner 18. A pump 5 supplies fuel to the burner. The turbine admission valve 28 is controlled by a piston 29 subject to the pressure in the pressure line beyond the throttle valve 10a and simultaneously with any change in the quantity of fuel delivered a change occurs in speed of the turbine driving the air compressor 4. The speed of the turbine is controlled by a sleeve 13 which is actuated by a bell-crank connected to a piston 21 subject to the pressure in the pipe line connected to the regulator 11 the function of the sleeve being to control ports through which leakage of transmission fluid can occur and so maintain the appropriate pressure in the pipe line for the regulation of the valve 28. Associated with the sleeve is an internal piston which is controlled by a centrifugal speed governor 27 and imposes an additional regulation on the outflow ports in the sleeve. In an emergency, the supply of steam to the turbine can be cut out by a device 33 which acts upon a-piston connected to a valve 34.
