[Class 40 (iv)] In a motor-driven switch provided with an electromagnetically-controlled latch member, the arm carrying the latch is made resilient longitudinally to absorb the energy of the switch on stopping. The switch shown is of the type described in Specification 388,173 and comprises a main supporting plate 1 detachably fitted to the switch bank by a lug 2 and screw 3 as described in Specification 406,840. The plate 1 carries the motor magnets 12, 13 on brackets 10, 11, the shafts for the intermediate pinion 14 and the wiper-carrying wheel 5, the off-normal springs 8 adjustably mounted on a bracket 9 and controlled by a cam 7, and a second plate 28 carrying as a unitary structure the latch magnet 33 and the latching mechanism. The latch arm consists of two bowed springs 43 fixed at one end in a groove in the toothed latch member 47 and at the other end to the armature 42 of the latch magnet by rivets, one of which 45 serves as a pivot for the armature. The restoring spring 50 acts directly on the latch member 47 to prevent bouncing and is adjustable by a screw 54 engaging a reinforcing spring 49. One of the contacts 48 in the motor circuit is carried on the latch member 47 and the other 53 on a further spring 52.

Title: Method of extraction of technically valuable products from emulsions, sludges, slurries, pulps, mashes, ground seeds and fruits and solid-water mixtures, by means of solvents
Inventor: JONES GWYNFRED
IPC: C11B1/10
Filed: 1946-01-16
Abstract: Oils, fats and waxes are extracted from emulsions, or sludges, slurries, pulps, mashes, and other solid-water mixtures by contacting the multi-phase mixture, treated as though it were a single liquid phase, with a polar solvent which is immiscible or incompletely miscible with water and is capable of dissolving fats &c., then separating the resulting solution from the mixture and separating the extracted products from the polar solvent.  By the term "polar solvent" is to be understood a solvent composed predominantly of an organic compound or compounds which will dissolve the fatty or waxy particles to be extracted and which has in its molecule at least three carbon atoms and an electro-negative group.  Any other component of the polar solvent serving also to dissolve the particles must not itself be completely miscible with water.  The solvent may be volatile and recovered by distillation and a low percentage may be added first to the mixture to be extracted and the latter then extracted with a larger percentage of solvent.  In one of the examples given, greasy spent wool scouring liquor is mixed with 4 per cent by volume of fusel oil and then submitted to a two-stage liquid-liquid extraction at about 55 DEG  C. with twice its volume of fusel oil, partially used fusel oil being used for the first stage and fresh fusel oil for the second stage.  The fusel oil is recovered from both the raffinate and extract by steam distillation.  In another example, castor seeds stripped of their husks and skins and finely powdered are mixed with water to form a thin cream and subjected to successive extracting with n-butyl alcohol which is then distilled off from the extracted oil with steam.  Two or more technically valuable fatty products may first be extracted together by means of the polar solvent and subsequently separated from each other and from the solvent.  For example, wool grease and soap may be extracted from spent wool scouring liquor with fusel oil and the soap then extracted from the latter by washing with water containing 0.02 per cent of crystalline tri-sodium phosphate and sufficient caustic soda to neutralize the free organic acids present.  A substantial proportion of the soap is present in the aqueous layer and technical grade wool grease not containing more than 3 per cent free fatty acids in the washed fusel oil layer.  Other polar solvents which may be used are the amyl alcohols, iso-butyl alcohol and cyclohexanol.

Abstract: 1326471 Hydrostatic transmission control LINDE AG 14 Jan 1971 [15 Jan 1970 10 April 1970] 1775/71 Heading F2D In a control system for a hydrostatic transmission wherein a follow-up servo motor 9 adjusts the displacement of a pump 1 in response to movement of a pilot valve 14 actuated by pressure liquid supplied through lines 15, 16 from manually controlled valves 17, 22, a bleedoff valve 34 responsive to an operating parameter (e.g. speed or torque) is connected through a shuttle valve 31 to the control pressure lines 15, 16 downstream of restrictors 33. As shown, pumps 1, 41 of identical hydrostatic transmission driving tracks on opposite sides of a vehicle are driven from a common engine and are in closed circuit with the variable displacement motors 4, 44. A manual control 39 selectively actuates control valves 17, 22, 57, 62 which supply pressure liquid frcm an auxiliary pump 6 through control pressure lines 15, 16, 55, 56 to opposite ends of the pilot valves 14, 54 to effect idential or differentical displacements of the pumps 1, 41. The control pressure lines 15, 16, 55, 56 are additionally connected through shuttle valves 23, 63 to pilot valves 25, 65 controlling follow-up servo motors 28, 68 which adjust the displacements of the motors 4, 44. The spring loading of the pilot valves 25, 65 is such that the motor displacement, remain unchanged until the pump displacements are maximum. The control pressure lines 15, 16; 55, 56 are additionally connected through shuttle valves 31, 71 to the bleedoff valve 34 which, as shown, is normally held closed by a centrifugal governor 35 responsive to engine speed. When the engine speed falls below a predetermined value a spring 36 moves the valve 34 left to vent the control pressures and thus reduce the pump displacement. The spring 36 is adjustably loaded by a lever 37 connected to the engine fuel control. The bleedoff valve may be controlled by a governer responsive to output speed to prevent excessively high output speeds. In Fig. 2 (not shown) a hydrostatic transmission for the hoist of a crane has an electromagnetically actuated bleed-off valve (130) controlled by the load on the hoist. The line (126) between the control pressure lines (123, 124) and the bleed-off valve (130) is additionally connected to the actuator (133) of a valve (134) controlling admission of pressure liquid to a brake release cylinder (136) so that when the valve (130) vents the line (126) on overload, the valve (134) automatically applies the brake to the hoist.

Abstract: Alpha olefins, e.g. ethylene, propene, butene, heptene or dodecene, are polymerized in the presence of a catalyst of which a component of composition TiCl3 0,33AlCl3 is prepared by reducing titanium tetrachloride with aluminium powder (see Group III).  Such a component, which is used in association with an aluminium alkyl, may be free of unreacted aluminium. Alternatively, up to 10% excess aluminium may be present when the titanium tetrachloride is reduced, and such aluminium may be retained in the final polymer to impart a metallic colour, or it may be removed from the polymer by treatment. with alcohols, followed by aqueous acid treatment The polymerization may be effected in the presence of an organic diluent, such as paraffinic hydrocarbons, mineral oil, naphthenes, benzene, toluene and xylene.  Specification 843,408 is referred to.ALSO:Crystalline titanium lower halides, particularly titanium trichloride, are prepared by intimately contacting titanium tetrahalide with aluminium powder at 20-100 DEG C.  Excess titanium tetrachloride, or excess aluminium up to a maximum of 10% above the stoichiometric amount, may be employed.  The contacting is normally effected in a ball mill and may be effected in the presence of organic diluents for example n-heptane, n-decane, cyclohexane, toluene or xylene.  The reaction product may be washed with the same inert diluent, filtered, and dried at for example 50-100 DEG C., after which it may be ball-milled and again taken up in an organic diluent.  The crystalline lower halide so produced is particularly suitable as a component in a catalyst for the low pressure polymerization of alphaolefins: its composition is expressed as TiCl3.0.3.AlCl3.  The reduced titanium chloride may be activated by metal-containing compounds such as trialkyl, dialkyl or monoalkyl aluminium compounds.  Specification 843,408 is referred to.
