Title: Improvements in the extraction of unsaponifiable matters from dry-saponified wool grease soap
IPC: C11D13/02
Filed: 1941-12-12
Abstract: 553,322. Soap manufacture. SMITH, H. W., and CAMPBELL, S. G. Dec. 12, 1941, No. 16062. [Classes 32 and 91] [Also in Group IV] To facilitate the extraction of unsaponifiable matter from wool grease soap produced by the dry saponification of wool grease with anhydrous. caustic alkali according to the process of Specification 470,715, the soap direct from its molten state at about 500‹ F. is spread into a thin sheet and rapidly cooled to render it tough and plastic, to a temperature of about 200‹ F., and then subjected to milling or ribboning. The process may be effected by running the soap from the soaping vessel in a thin layer on to a wide sheet metal conveyer under which cold air is blown. The congealed sheet detaches itself from the end of the conveyer and is then fed to the milling machine. If the latter be provided with a serrated scraper, ribbons of the soap are formed. The soap is now in a readily extractable form for removing the unsaponifiable matter. The solvents comprise mixtures of acetone with any volatile solvent which normally dissolves oils and fats but not soap. A solvent consisting of equal volumes of acetone and dichlorethane is preferred ; other mixtures specified comprise acetone with trichlorethylene, carbon tetrachloride or benzine. The acetone is recovered from the extract by using a continuous still or column under, vacuum and removing it before contact with surfaces of high temperature or with concentrated alkali residues. A suitable apparatus comprises a fractionating column provided with a number, such as sixteen, of steamheated shelves or hot plates. The acetone is removed near the top of the column and the dichlorethane at a lower stage, the solvent-free residue being withdrawn at the bottom. The unsaponifiable oil may be deodorized by steaming it whilst heating it in a vessel under vacuum.

Abstract: 448,301. Endless - belt conveyers. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.-(Paetzold, E. E. ; Pomona Nurseries, Ceres, Cape Town, South Africa) June 4, 1935, No. 16176. [Class 78 (i)] An endless-belt conveyer for use in picking fruit comprises a portable frame 1, with a supporting strut or struts 9, adapted to be set up near a tree, the picked fruit being placed in the uppermost of open-mouthed pockets 5 carried by an endless belt 4 passing over rollers 2, 3 at either end of the frame, the fruit being lowered to the ground and discharged into a receptacle 8 by its weight. A brake for stopping or retarding the movement of the conveyer comprises a cord (not shown) secured at one end to the frame, and passing round the upper roller 2 or a pulley secured to the shaft of that roller. When, as shown, a single strut 9 is provided, it terminates in spaced arms 10 pivotally connected to adjustable sleeves 17 on the side frame members 1. Alternatively, the pivotal connection may be between the strut 9 and the arms 10. Slats 12, or a single wide slat, secured to the frame 1 support the front loaded portion of the belt. The Provisional Specification describes also a construction in which a tie-rod or rope at the front of the frame is employed in place of the strut 9.

Abstract: 273,098. Newman, A. S. June 29, 1926. Kinematograph apparatus.-In gates comprising a fixed part a, a hinged part q which grips the film between feed movements and releases it during such movements, a pin h carried by the part a and entering a perforation t in the part q, and fixed film guides c, guides u are carried by one side of the hinged part q, a perforation v in one of the guides u surrounds the pin h, and the fixed part a is cut away at g to accommodate the guides u. The part q consists of a plate having an exposure opening r, and is carried by a bar p hinged on a pin n. The part q may be turned into the position shown in Fig. 2, or completely through 180‹, for cleaning, and has a hook x engaging, when the gate is closed, an adjustable leaf spring k; the spring k, in conjunction with a screw 5 on a bell-crank 3 rocked bv an eccentric z on the crank shaft of the claw feed, produces oscillation of the part q into and out of the gripping position. Slots s, at one or both sides of the opening r, are formed in the two parts a, q of the gate to accommodate one or two feed claws, and the claws are such as to engage and feed the film when it is lifted from the part a by the guides u. The perforations v, t fit loosely round the pin h, and film dust &c. settling on the pin h may escape through the perforation v and clearance space g. The oscillating movements of the part q may be produced by a cam in conjunction with a spring, or wholly by mechanism, and the intermittent mechanism may be dispensed with, the flexibility of the film loops being relied upon to produce the intermittent feed.

The system is disclosed as applied to a twin hull ship provided with pairs of winches for anchor ropes at respective corners. Legs, with raising and lowering apparatus, may also be provided at the corners. As shown, the position correction system comprises a detector 310 for the orientation angle of each rope and an information setter 320 into which data, relating to desired movement, is set manually, and a comparator 330 for determining the deviation between actual and desired positions. A position correction pattern designator 340 determines the required movement and whether a parallel or swinging correction is necessary and modifies the circuit arrangement of the information setter accordingly. The output from the comparator is fed to a rope extension and contraction control device 350, which also receives a signal from setter 320 regarding the stroke. The device 350 provides a signal to the winch for paying out or taking in the anchor rope in steps corresponding to a unit length. The Specification discloses the selection of position determining parameters and the assumptions made to facilitate control.

In a motor vehicle, a simple sun-ring-planet train 2 splits torque between input and output shafts an, ab, into a mechanical path and a hydrostatic path whereof the piston cylinder unit I is permanently driven through a wheel pair 6, 5 by a reaction ring gear 4 of the train, whilst the communicating piston-cylinder unit II is clutched at 8 to the output shaft ab at speeds below a change-point at which the ring-gear 4 ceases to rotate forwardly and begins to rotate reversely, and clutched at 8<SP>1</SP> to the input shaft an above that change-point, the arrangement being subject to a control responsive to input speed, accelerator position of the driving I.C. engine (torque factor) and a feeler 37 detecting the change of direction of the reaction ring gear 4, whereby the inclination of the swash-plates 14 of both units, and the clutch change are all atuomatically controlled, preferably to follow minimum fuel consumption lines of the engine. A practical embodiment, Fig. 7, not shown, has two pairs of units I, I<SP>1</SP>, and II, II<SP>1</SP>, grouped circumferentially around the gear train and operated in unison by the arrangement shown. An engine-driven pump 25 supplies servo pressure 27 to shift the clutches 8, 8<SP>1</SP> and swashplates 14, and input-speed responsive pressure on opposite sides of a piston 24 by pressuredrop across a delivery orifice 30. Speed-responsive rightward movement of the piston 24 is opposed by a spring 31 loaded by the engine accelerator pedal 34 (torque factor) and the piston actuates a valve 33 supplying servopressure 27 through a manual change-over reversing valve 36 to opposite sides of a servopiston rack 22 which, through a pinion 21, cranks and connecting rods 20, and servopistons 19, adjusts the swash-plates 14 in a sequence (Fig. 9, not shown) related to the clutch change-over. The latter is performed by a servo piston 39, energized through a two-way valve 38, actuated by a feeler 37 which is pivoted one way or the other according to the direction of rotation of the underlying toothed wheel 6 connected to the ring gear 4 of the planet train.
