Abstract: 129,137. Rudd, H. July 16, 191R. Cleaning - devices for nozzles. In atomizers wherein the nozzle comprises a spring-held piston, the spring is so arranged that the nozzle is normally held telescoped so that a centrally-disposed pin protrudes through the orifice. The nozzle B is normally held telescoped by a spring J so that a pin H' carried centrally by a spider H protrudes through the orifice. On the admission of pressure fluid, the nozzle moves forward. The invention is described as applied to apparatus for spraying chemicals or the like, in which pressure fluid from one nozzle passes across the face of another nozzle to which the chemical is supplied. This second nozzle may be held open normally, or may be operated through a by-pass by the pressure fluid. In a modification, the chemical nozzle projects into the pressure-fluid conduit, the chemical being drawn up by the rush of fluid. In this case, the nozzle B carries a rearwardly projecting pin which, in the inoperative position, enters the secondary nozzle.

Title: Improvements in perforated card controlled machines
Filed: 1927-05-03
Abstract: 279,023. Accounting & Tabulating Machine Corporation, (Assignees of Paris, R. E.). Oct. 12, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Printing totals. - Card-feeding devices. A " grouped-card " statistical machine has card-feeding means which, instead of being stopped at total-taking when the card group changes, continue to feed the cards at a slower rate. The invention is described as applied to the machine of Specification 269,946. The picker blade 115 is reciprocated by a lever 117 pivoted at 118 and having a pin 119 normally engaged by a claw arm 120 pivoted to the bar 121 which is cam-operated as in the prior case to feed the cards at the normal rate during tabulating. Coacting with the claw arm 120 is a bell crank 145, 147 pivoted at 146 and controlled by a cam 148 on the shaft 36, which latter rotates only at totaltaking, as in 269,946; a second cam 151, together with a spring 152, operates a lever 149 so that when the shaft 36 rotates counterclockwise, Fig. 1, the bell-crank 145, 147 rotates counterclockwise to disengage the claw 120 from the pin 119, this pin 119 being then actuated by the lever 149 and cam 151 at a slower rate. The links 135 which cause the reciprocation of the plate 77 carrying the cardengaging hook 127, Fig. 10. have notches 136 engaging a rod 137 on arm 138, as in the prior case. To prevent the hook 127 from carrying the first card of the new group out of the throat 76 during total-taking, the arms 135 are raised at this time to disengage notches 136 from rod 137 by means of bell-crank 153 operated by linkage 155 156 from the shaft 146, which has turned counter-clockwise. A beak 120<a> on the claw 120 prevents premature engagement of the claw with the pin 119 as the latter moves to the left under the influence of the arm 149. At the end of the single total-taking rotation of the shaft 36 the cam 148 lowers the claw 120 which engages the pin 119 as the latter moves to the right.

Title: Device for accurate and selective control in relation with a displacement
IPC: G01J3/32
Filed: 1951-05-21
Abstract: 694,536. Machine tool details. COMPAGNIE RADIO CINEMA. May 21, 1951 [May 25, 1950], No. 11788/51. Class 83 (iii). [Also in Groups XXXVII and XL (b)] In apparatus in which a carriage is advanced along a path, at various points in which the carriage is to effect the selection of one of a number of controls, the points are located by a pair of scales parallel to the path, the arrangement being such that the carriage locates a point on the scales and then carries them with it so that one scale selects the appropriate control and the other operates to control the carriage feed. The carriage may effect a number of operations of a machine tool in accordance with a programme set out on the scales. The two scales 18, 12 have a number of slots, scale 12 containing only slots corresponding to those points at which measurements are to be made while scale 18 contains those corresponding to every possible measurement. Attached to the carriage 1 and sliding on a square-sectioned rod 10 is a member 5 having two lugs 6, 7 sliding respectively on scales 12, 18. This member is spring-loaded so that as the carriage is traversed the lug 6 enters slot 37 in scale 12 while lug 7 enters slot 38, simultaneously rotating a contact arm 24 to slow down the carriage advance motor. The extent to which lug 6 enters the slot 37 is determined by a stop member 33 below the slot. The carriage now advances slowly carrying the scale with it and compressing springs 17, 20. When the carriage is over the part to be measured, scale 18 operates a contact 22 to stop the carriage motor, to set in operation a timing mechanism (not shown), and to energize a magnet 14. Magnet 14 slides the square section rod back through the member 5, compressing a spring 15 and engaging a contact member 29 with one of contacts 30-32 to adjust the amplifier sensitivity. (The particular contact is chosen by the extent of entry of lug 6 into the slot 37.) After a period the timing mechanism de-energizes magnet 14 and energizes a magnet 28 to withdraw lugs 6, 7 from the slots in the scales. Springs 17, 20 now restore the scales to their original position and the carriage continues its travel. At the end of the carriage travel a lug 56 on the carriage engages with a block 49 on a sliding rod 47 which, through contacts 56, reverses the carriage drive motor and feeds magnet 28 to hold the lugs 6, 7 away from the slots. The carriage returns to the starting point and by contacts 54 stops the whole apparatus. The controls may be replaced by an hydraulic system with the spring contacts being replaced by slide valves, the magnets by pistons responsive to fluid pressure and the arm 29 may act on the distribution valve.

Title: Improvements in and relating to thrashing or high speed beating machines for thrashing or beating liquids
IPC: A23G3/02
Filed: 1920-04-28
Abstract: 166,994. Fryer, F. G., and Rowntree & Co., Ltd. April 28, 1920. Continuous-discharge apparatus with stationary containers.-Relates to thrashing or high-speed beating-machines for thrashing and beating liquids, preferably in the presence of air, and more particularly for thrashing mixtures of cocoa liquor, sugar, and other ingredients in the manufacture of chocolate fondants. The machine is of the type in which a high-speed rotor works. within a stator, the material being passed through the narrow clearance-space between the rotor and the stator and thrashed or beaten by blades, - pins, projections, or the like on the rotor or stator, or both; or the rotor and stator may be stepped or corrugated. According to the invention, means are provided for admitting water or other fluid to the interior of the rotor, or circulating a current of fluid through it, to control the temperature of the rotor. As shown in Fig. 1,. water is admitted to the hollow rotor 4 through its hollow shaft 3 and extension 37. The water is supplied through a funnel 57 and passes through inlets 58 in the collar 53 to which the rotor is bolted. The water escapes by a pipe 59 into the hollow shaft 3 and is collected in a vessel 60. The extension 37 carries a worm 36 working within the feed-hopper 32. Air is supplied to the liquid under treatment through an inlet 40 in the outer casing 33 of the hopper 32 as described in Specification 166,995. The air may be supplied by a fan or blower and passes through inlets 56 in the casting 20 of the cover-plate 11 of the stator. The space between the two members.20, 21 of the cover-plate is divided into two concentric parts by means of an annulus 55, and the outer space may serve as a heat-jacket. In another arrangement, Fig. 2, water is admitted through a pipe 80 and injected or sprayed through the inlet 81 on to the interior top surface of the rotor 4. The water drains into a trough 82 in the interior of the stator and escapes by an outlet 83. An annular guard 84 prevents the water from reaching the bearings of the shaft 3, and an extension 85 of the vertical wall of the rotor prevents it from reaching the liquid under treatment. The base 6 of the stator to which the trough 82 is secured by bolts 91 is cast in one with the walls of the jacket 15. The invention is particularl<y> applicable to machines of the kind described in Specification 165,844.

Filed: 1962-03-30
Abstract: 938,707. Computing tristimulus values. TOKYO SHIBAURA ELECTRIC CO. Ltd. March 30, 1962 [April 1, 1961], No. 12268/62. Class 40 (3). [Also in Group XIX] In the computation of tristimulus values from the output of a spectrophotometer, the wide spacing between measured spectral lines associated with the selected ordinate method and the inconvenient multiplications of the weighted ordinate method are avoided by using a hybrid method. The spectral lines to be measured are weighted by a power of two lightly in regions of small C.I.E. coefficients and heavily in the regions of high coefficients, and the outputs of the lines summed. The positions of the lines are chosen so that the sums represent the tristimulus values directly. Spectrophotometer 1 produces, 150 times per second, a group of pulses at terminal 24 which are proportional in number to the percentage reflection or transmission of the spectral line being measured at that instant. The group is preceded by a starting pulse from terminal 26 and followed by a stopping pulse from terminal 25. A wavelength signal generator 2 is coupled to the wavelength drive of the spectrophotometer 1 produces a pulse at 27 at the selected wavelengths which set a flip-flop 3 to cause the next starting pulse from 26 to open a gate 4 to pass the pulses from 24 to the accumultors 18, 19, 20. Signals from terminals 28-40 open appropriate ones of gates 5-17 to introduce the pulses into the accumulators at points which give the predetermined weighting. The stopping pulse from 25 resets flip-flop 3. Accumulators 18-20 feed into decimal counter circuits 21-23, and neon lamps show the state of count remaining in the accumulators. Formulae for the selection of wavelengths are given.

Title: Process of manufacture of normal butyl esters of amino-benzoic acids
Filed: 1925-05-12
Abstract: 252,870. Marks, E. C. R., (Abbott Laboratories). May 12, 1925. Grant of Patent refused. n-Butyl esters of aminobenzoic acids are obtained by treatment of the metallic salt of the acid with n-butyl halide or by forming the n-butyl ester of the corresponding nitrobenzoic acid by a similar reaction and reducing by known means. In one example a mixture of sodium p-aminobenzoate and n-butyl bromide, preferably together with a small quantity of a secondary amine such as diethyl-, dipropyl-, or dibutyl-amine or copper powder to act as a catalyst is refluxed and the excess of n-butyl bromide removed by vacuum distillation. The residue is extracted with water and then with alcohol. The alcoholic extract is concentrated and dried and on cooling yields white crystals of n-butyl-p-aminobenzoate. In a second example a mixture of dry sodium pnitrobenzoata and n-butyl bromide with a small quantity of diethylamine as catalyst is refluxed. The excess of n-butyl bromide is removed and the residue extracted with water and ether. The ether extract after drying and distilling gives nbutyl.p-nitrobenzoate in the form of an oil. The latter is reduced, for example by means of an iton and hydrochloric acid, the amino compound being extracted from the product by means of ether after it has been rendered alkaline.
