Title: Improvements relating to the production of alkyl tin chlorides
IPC: C07F7/22
Filed: 1954-05-07
Abstract: Alkyl tin chlorides are prepared by reacting equimolar quantities of an alkyl tin and tin tetrachloride without application of external heat.  The reaction mixture is maintained between 0 DEG  and 100 DEG C. and preferably between 0 DEG  and 20 DEG  C. by cooling, thus increasing the yield of the monoalkyl tin trichloride and the trialkyl tin monochloride.  Specified compounds which may be prepared include propyl tin trichloride, tripropyl tin monochloride, butyl tin trichloride, tributyl tin monochloride, amyl tin trichloride, triamyl tin monochloride, nonyl tin chlorides such as 3,3,5-trimethylhexyl tin trichloride and tri(3,3,5 - trimethylhexyl)tin monochloride.  The reaction mixture may be separated by vacuum fractionation, fractional crystallization, or steam distillation.  In an example tin tetrachloride is added to tetrabutyl tin with stirring at room temperature.  The reaction mixture after standing is vacuum fractionated at 100 mm. pressure to give a fraction comprising substantially pure butyl tin trichloride.  The still residue is refrigerated and centrifuged to remove a portion of the dichloride, leaving an impure tributyl tin monochloride contaminated with the dibutyl tin dichloride.

IPC: G07F17/42
Abstract: 135,258. Brown, T. J., and Fry, W. H. Nov. 15, 1918. Delivery of tickets; coin action, mechanical-connexion and multiple-coin.-Apparatus for the sale of tickets &c. is so constructed that it may be operated when there are present in the shoot two coins of different size and value, such as a penny and a halfpenny, or three coins of the smaller size, The apparatus comprises a coin shoot 2 and a member 3, pivoted at 4 and having a nose-piece 5 and a tail-piece 6 which extend into the shoot and engage coins placed therein. The upper part of the shoot will admit a penny, but not the lower, which is, however, adapted to receive more than one halfpenny, side by side and resting on ledges 9 in the path of a spring-controlled rocking arm 10. A pawl 13 on the spindle 11 of the arm 10 operates in connexion with stationary racks 15, 16, a pin 17 on the pawl engaging the rack 15 and the nose of the pawl engaging the rack 16. A slidable plate 20 for delivering the tickets, and moved by a handle 21, carries a bracket 22 in which the ledges 9 and spindle 11 are fixed, and also has two horizontal arms 23 passing through a slot on which a penny rests when in the shoot. On the actuation of the apparatus when a penny is in the .slot, the bars 23 slide until a wider part thereof arrives beneath the penny, and, at the same time, a switch arm 25 pivoted at 26 is moved by the engagement of a nose 29 on the sliding bracket 22 with a lever 28 connected to an arm 25<x> on the pivot 26 by a spring 28<x>, so that the falling coin is diverted into a receptacle. The presence of a penny in the upper position and a halfpenny in the lower, or three halfpennies in the lower position, so limits the motion of the recker 3 that the arm 10, when drawn forward into engagement with a coin or coins in the lower part of the shoot, is able to raise the pawl 13 sufficiently to clear the stop 16<x> of the rack 16 and enable the slide to be drawn out. In this motion, the pin 17 engages a pawl 31 on the rack and is guided upon to the rack 15, which prevents its return until the drawer has completed its stroke. A tongue 34 projecting from an upward extension of the slide 20 closes the coin slot as the stroke is made. A gravity pawl 35 is provided in the shoot to prevent halfpennies from rising owing to the pressure of the arm 10.

Title: Method of and apparatus for determining the mean size of given particles in a fluid
Inventor: CARR-BRION KENNETH GARFIELD
IPC: G01N23/12
Filed: 1966-03-28
Abstract: 1,127,342. Photo-electric measurement of particle size. NATIONAL RESEARCH DEVELOPMENT CORP. March 15, 1967 [March 28, 1966], No. 13598/66. Heading G1A. The mean size of solid particles of a partic - ular substance, in a fluid is measured by passing through the fluid, X- or γ-radiations containing two different respective energies or energy bands, such that the intensities of these radiations of different energies after transmission through the fluid are respectively independent of, and dependent on, the mean size of the particles of interest, and comparing the respective intensities. The different radiations can be detected simultaneously or sequentially. In one arrangement, Fig. 2, the fluid flows through two sequential absorption cells C 1 , C 2  the thicknesses of which are different such that the absorption in the cells in the absence of particles in the fluid, is the same. The sources S 1  and S 2 , emitting beams E 1 , E 2 , are chosen so that the beam of energy E 1 , is affected markedly by the substance of which the particles are formed, and thus responds appreciably to changes in mean particle size, whereas the beam of energy E 2  shows a negligible effect. This may be done by selecting an energy for the beam E 1  just exceeding the absorption edge of an element present in large proportions in the substance of which the particles to be investigated are formed. Thus, for example, in the analysis of a slurry of particles of barytes (barium sulphate) and quartz in water, the mean size of the barytes particles is determined using beams of X-rays obtained by irradiating targets of tin (E 1 ) and bromine (E 2 ). The quartz particles do not affect the measurement since they absorb neither beam to any important extent. A comparison of the transmitted intensities through cells C 1  and C 2  is made by detection by scintillation counters D 1  , D 2 , the outputs of which are fed to comparator CR. A series of measurements on samples of different solid/liquid ratio are carried out and the graph obtained compared with calibration curves such as those of Fig. 1 (not shown). The targets may be irradiated by a common source or respective primary sources e.g. X-ray tube or radioisotope. Alternatively, the beams may be produced as primary beams from respective X-ray tubes or isotopes emitting the required energies (monochromatic or narrow band width). In alternative arrangements, Figs. 3 and 4 (not shown) only one absorption cell is used, the source emitting radiation containing both energies E 1 , E 2 . The absorption of the different energy radiations is distinguished either by using a pair of balanced filters which are switched into the beam path one at a time, or by simultaneous measurement of the intensities of the different energy radiations by use of a two-channel pulse energy selector.

Title: Improvements relating to fuel injection or like pumps
IPC: F02M59/26
Filed: 1934-05-05
Abstract: 421,443. Liquid - fuel injectors. GENERAL MOTORS CORPORATION, Detroit, Michigan, U.S.A. May 5, 1934, No. 13677. Convention date, May 5, 1933. [Class 7 (iii)] [See also Group XXVIII] A fuel-injection pump comprises a cylinder 6 provided with an inlet port 9 and a byepass port 10 which may be provided with a non- return valve 48 comprising a spring plate clipped to the exterior of the cylinder. The plunger is provided with two inclined surfaces 3, 4 and an axial groove 5connectingthepressure space with the space between the edges 3, 4. During a delivery stroke, the plunger first cuts off the inlet port 9 and then the fuel together with any air is byepassed through the port 10 until it is cut off by the edge 4. Delivery of the fuel then takes place through passages '34 to lift the valve 40. Delivery ceases when the edge 3 uncovers the port 9. The output is varied by rotating the plunger by a pinion 15 mounted upon a portion 17 of the plunger. The nozzle 42, valve seating 29 and spring housing 30 are mounted within a nipple 31 screwed into the casing 7, thus causing engagement between the cylinder 6 and casing 7 at 32. The bore 11 leads to the annular space 8 for free supply and the bore 12 forms an air cushion above the fuel. The casing 7 is bolted to the cylinder and the conical surface on the nipple 31 forms a seating. Ports 46 and 47 lead away leakage fuel to the port 58.

Filed: 1963-04-08
Abstract: 1,097,031. Control systems for arc-welding apparatus; control of D.C. motors. BRITISH OXYGEN CO. Ltd. July 7, 1964 [April 8, 1963], No. 13849/63. Headings H2H and H2J. An arc-welding process in which a consumable wire electrode is continuously fed to the welding point is provided with means whereby for a timed period, the power supplied to the welding arc and the rate at which the electrode is fed to the welding point are simultaneously increased. The feed motor control circuit is shown in Fig. 1, the speed of the motor 1 being controlled by a governor 3 which controls the armature current by means such as thyratrons or silicon controlled rectifiers. When an arc is required at increased power and feed rate a switch 14 is moved to the position shown whereupon the capacitor in a timing circuit 11 becomes charged. When a welding operation is initiated a relay 9 is energized to change-over a contact 10, thus allowing the capacitor in the circuit 11 to discharge into and energize a relay 8. Energization of this relay closes a contact 7 to place an adjustable resistor 6 in parallel with the speed governor 3 so that the speed of the feed motor 1 is increased. Energization of the relay 8 also opens contact 23 (see Fig. 2) and closes contact 24 whereby the excitation of the welding generator field 20 is increased to increase the output thereof. The excitation of the field 20 may alternatively be controlled by means of a saturable reactor. A switch 16 is provided for testing purposes and contact 17 provides a safety device. The discharge time of the capacitor in the circuit 11 and hence the period of increased power and feed rate is between 0À2 and 0.5 seconds.

Abstract: 742,381. Annealing glass. SOC. ANON DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.- GOBAIN, CHAUNY ET CIREY. June 2, 1950 [June 2, 1949], No. 13900/50. Class 56 A method of annealing glass consists in subjecting the glass, while it is at a temperature corresponding to a viscosity of the order of 10<SP>15</SP>-10<SP>17</SP> poise, to the action of a high-frequency electric field without bringing the glass to a temperature at which its viscosity is substantially less than 10<SP>15</SP> poise. Immediately after the application of the high frequency field is discontinued cooling may be carried out at a speed which is only limited by the risk of breakage. The glass may be brought to the required temperature during manufacture by cooling, or, if it is already solidified, it is heated to that temperature, e.g. by utilising the diathermic effect of the high frequency field which will directly produce the annealing effect when the suitable temperature has been reached. The method permits of shortening the duration of the annealing operation. Thus in an example, glass 8 m.m. thick is heated to 400‹C and subjected to the action of an alternating electric field of a frequency of 12 megacycles per second for two and a half minutes, followed by cooling for not more than ten minutes.
