Title: Process for extracting materials containing oil or fat
Inventor: STOEBE ROBERT
IPC: C11B1/10
Filed: 1952-01-15
Abstract: Materials containing oil or fat, such as fish, carcasses, oil seeds and glue boiler residues, are extracted by first opening up the material by means of superheated steam, then extracting with liquid perchlorethylene, which is distilled to move water from the material, separating the resulting defatted material from the liquid, washing it with perchlorethylene, then passing perchlorethylene vapour through the material, and finally removing residual perchlorethylene therefrom by means of superheated steam. The initial material after treatment with the super-heated steam forms a homogeneous mass of a temperature, e.g., of 119 DEG C.  Since the boiling point of perchlorethylene is 119 DEG C., distillation of the latter dehydrates the material and enables better penetration of the remaining solvent to effect intensive de-fatting.  Any remaining moisture and excess solvent in the de-fatted material are removed by the step of passing the perchlorethylene vapour there-through, which step is continued until the vapours in the condenser reach 119 DEG C.  The final steaming step is effected by steam at, e.g. 115 DEG C.  A dry colourless, powdered and de-fatted material is obtained suitable as food for animals.ALSO:Food for animals is obtained from materials containing oil or fat, such as fish, carcases, oil seeds and glue boiler residues, which are extracted by first opening up the material by means of superheated steam, then extracting with liquid perchlorethylene, which is distilled to remove water from the material, separating the resulting defatted material from the liquid, washing it with perchlorethylene then passing perchlorethylene vapour through the material, and finally removing residual perchlorethylene therefrom by means of superheated steam.

Title: Improvements in or relating to clockwork-operated fuses for projectiles
IPC: F42C9/04
Filed: 1927-01-14
Abstract: 264,525. Schwob Freres et Cie, Soc. Anon., and Varaud, A. Jan. 16, 1926, [Convention date]. Projectile fuzes.-Relates to clockwork fuzes of the kind in which the driving member is arranged axially within the fuze body and performs several revolutions for the maximum dura.- tion of movement of the fuze. According to the invention, the housing of the clockwork mechanism is in two parts, one fixed to the body of the fuze, and the other rotatable to permit the simultaneous winding and setting of the fuze before discharge, means being provided for locking this movable part on discharge and releasing the drive. As shown, the fixed part 7, 8. 9, Fig. 2, of the housing is secured by screws 11 inside a split casing 10 adapted to be placed in a chamber 6, Fig. 1 in the fuze body 1 2, and to be prevented from rotation therein by means of tenons and mortises; and the movable part 13, 15 is mounted in the upper end of the casing 10 and is provided with a toothed rim 24 engaged by triangularly toothed spring pawls 25 attached to the casing 10. The fixed part of the housing contains the driving spring 28 connected to a shaft 29, which carries at one end a pinion 30 adapted to actuate the trigger of a spring striker 33, and at the other end a toothed wheel 35 in mesh with a pinion 36 of the gear train mounted in the movable part of the housing. This movable part is covered by a plate 22, carrying a tenon 21 adapted to be engaged by the notched inner end of a key 3, which is firmly held in place in the nose 1 of the fuze body by means of an inclined grub-screw 5. When this key is turned in either direction, the ratchet device 24. 25 yields and allows the movable part of the fuze housing to be rotated to adjust the setting of the fuze and simultaneously to wind up its spring. On discharge, a ring 40, situated in front of the housing and normally held forward out of action by a spring 42, sets back by inertia and drives points 39 into the top plate 22 of the movable housing; and rebound of the ring is prevented by tongues 43 which open out into notches 44, or by a lever which swings over the ring 40 by centrifugal force. This action locks the movable housing against rotation. In addition, an inertia bolt 37 sets back and releases the balance 14, which also sets back while acceleration lasts, thereby remaining locked by a screw head 38 until acceleration is over, when the balance arms spring forward again and the clockwork is free to begin its movement. The Specification as open to inspection under Sect. 91 (3) (a) describes also various modifications of detail which are not illustrated. These do not appear in the Specification as accepted.

Title: A process for the production of derivatives of albumin cleavage products
Filed: 1933-01-13
Abstract: Albumen cleavage products which are probably acylated at the nitrogen atom, are obtained by causing high molecular cleavage products of animal and vegetable substances such as horn, casein, gelatine, and the like, for example a lye obtained in the acid or alkaline decomposition of leather waste, to react with the halides or anhydrides of higher saturated or unsaturated fatty acids, or mixtures of the same derived from different fatty acids. According to examples, (1) oleic chloride is condensed with technical sodium lysalbate, horn albumose obtained by decomposing horn shavings with lime, or caseose obtained by treating casein with soda lye; (2) gelatose obtained by decomposition of gelatine, is treated with chlorides of the fatty acids of linseed oil; (3) technical lysalbic acid is treated with stearic anhydride.  The Specification as open to inspection under Sect. 91 contains further examples relating to the treatment of a lye containing lysalbic and protalbic acids with oleic chloride; an acid leather waste lye with oleic and solid fatty acid (such as stearic) chlorines, an alkaline chrome decomposition lye with palmitic and stearic chlorides; technical sodium lysalbate with palmitic bromide; and leather waste lye with chlorostearic chloride; all the above condensations take place in presence of alkali. According to further examples, the products are employed, (1) as washing agents for carpet yarn; (2) as levelling agents in dyeing crosswound bobbins; (3) to prepare an emulsion with vaseline oil and neat's-foot oil for treatment of furs and leather; and (4) as wetting agents in mercerizing cotton.  This subject-matter does not appear in the Specification as accepted.

Abstract: 739,489. Water-tube steam boilers; steam superheaters. BABCOCK & WILCOX, Ltd. Jan. 14, 1954 [Jan. 16, 1953], No. 1368/53. Classes 123 (2) and 123 (3). In a steam boiler as described in Specification 738,092 comprising a vertical furnace chamber 1 from the top of which combustion gases flow through a lateral opening 19 and then successively through a horizontal pass 60 locating convection superheater sections and three parallel, damper-controlled downpasses 61a ... 61c locating, in the middle pass 61b a reheater and in the outer passes 61a, 61c, further superheater sections, slagging and overheating of the tubes in the middle regions of the superheater sections in pass 60, which would otherwise occur due to the high temperature of the central part of the furnace gas stream flowing through opening 19, which central part has been screened whilst in the furnace chamber by the outer, partially opaque, parts of the flame, is prevented by mixing with this high-temperature central part cooled, recirculated flue gas in sufficient quantity to lower its temperature to that at which the gas may be allowed safely to impinge on the tubes. The flue gas is withdrawn from the bottom of the downpass extension 85 through a flue 206 and delivered by a fan 330 through two ducts 301 leading one into each end of a windbox 300 disposed on the front wall 3 of chamber 1 opposite the opening 19. As shown in Fig. 3, the windbox is divided internally into seven sections 310 ... 316, the admission of gas to each section being controlled by a damper 320. Each section has an aperture group, numbered 303 ... 309 respectively, through which the flue gas flows to mix with the stream of furnace gas entering pass 60 at 19. In operation, excessive temperature of the core of the furnace gas stream is corrected by admission of flue gas firstly through aperture 306 and then, if necessary, because for example of an increased firing rate, through apertures 305, 307; 304, 308 and finally 303, 309. The distribution of flue gas between the apertures and regulation of the quantity of gas recirculated may also be used in conjunction with the adjustment of dampers at the bottoms of the three downpasses 61a ... 61c to control reheat and superheat temperatures.

Title: Improvements in machines for securing caps or closures in the mouths of bottles or other containers
IPC: B67B5/06
Filed: 1920-01-15
Abstract: 156,557. Tevander, O. N. June 26, 1915, [Convention date]. Capsules, applying.- A machine for applying spirited caps to milk bottles and other containers is provided with means for winding a string about the skirt of the cap and means for applying a fastener to the overlapping ends o f t h string. The bottle 3, Fig. 3, with a cap, preferably of paper, on its mouth, is placed on a seating 2 beneath a pair of jaws 4. These jaws move down over the bottle, as shown, and press the cap closely around the mouth leaving two projecting flattened ears 7, Fig. 17. These ears prevent the string from slipping off the skirt of the cap, the string 20 either being passed through the ears, as shown in Fig. 17, or about the narrow part of the ears, as shown in Fig. 20. The jaws 4 are pivoted on head 8 and are depressed at intervals, against the action of springs 9, by a cam-operated lever 16 to bring them about the mouth of the bottle. They are closed by contact with rods 19 and are opened, when the head rises, by the pull of the springs 9. The string 20 is fed into the machine between a clip 22 and a post 21, shown in plan in Fig. 1. The end of the string is gripped between fingers 23, 24 which reciprocate horizontally and draw the string in front of an oscillating prong 35. This prong swings about a shaft 37 and draws the string out into a loop, as shown in Fig. 4, between the upright arms of a U-shaped wire frame 45. The straight portions of the string are then engaged by hooks 46, 47, as shown in Fig. 4, which reciprocate transversely to the fingers 23. 24. The hooks pierce the lugs 7 of the paper cap in their forward movement, and thus draw the string through the lugs on their backward movement. A fixed knife 54 cuts the string and the movement of the prong to its first position permits the hooks to draw the string around the skirt of the cap. Two other hooks 55, 56 reciprocating in opposite directions, but transversely to the hooks 46, 47, next engage the ends of the string, withdraw them from the hooks 46, 47 and then cross them, thus drawing the string around the cap. A strip 70 of metal fasteners is fed forwards by a pawl 84 and a reciprocating bar 85, and the fasteners are cut off one at a time from the strip and are carried by grippers 71 into contact with the skirt of the cap. The jaws of the grippers are shaped to permit the passage between them of the hooks 55, 56 which thus draw the ends of the string between the jaws so that these ends cross in the fastener held in the jaws. The jaws then close the fastener in the string, thus clamping the overlapping ends firmly together.

In a circuit wherein a hot cathode discharge lamp 14 is supplied from a D.C. vibrator unit, the output transformer is arranged to supply both heating and discharge currents, also to have a high leakage reactance to dispense with the normal series choke. In the Figure a non- synchronous vibrator 2-5 fed from battery 1 is connected to a centre-tapped transformer winding 6, 7. To reduce the size of buffer condenser C3, it is fed at higher voltage from autotransformer winding 17. The secondary winding 9-11 comprises parts 10, 11 feeding heaters 12, 13, and the discharge current. The primary and secondary windings are wound on different parts of a three-limbed core 18 with magnetic shims 18d separating the two windings so that on starting, very little flux is carried by the shims, but on discharge commencing the magnetic leakage lowers the voltage across windings 9-11. In an alternative arrangement the primary and secondary windings are on different limbs of the transformer and an additional limb with an air gap is provided in place of the magnetic shims 18d.
