Abstract: 1,174,244. Fluid-pressure servomotor systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. June 21, 1967 [July 8, 1966], No.30717/66. Heading G3P. A manual input to lever 57 is converted to a proportional electrical signal which is transmitted to valve 51 which transmits a pressure signal to chamber 55 to move diaphragm assembly, 27, 28 rightwards to seat disc 17 of valve 15 at 19 and unseat the end of tube 20 from this disc. The right side of piston 5 is thereby exhausted via 24, 30, 29, 31 whereas the left side of the piston still receives fluid via 21, 23, 25. The consequent rightward movement of the piston 5 is fed back via link 7, crank 2, electrical transmission 63 and valve 61 to chamber 65 to balance the control pressure in chamber 55 to restore the diaphragm assembly to the position shown and arrest movement of the piston. When the supply pressure in line 21 falls below a predetermined level, diaphragm 46 rises to break the electrical supply to valve 8 to allow the latter to open to inter-connect opposite sides of the piston to allow direct manual operation of the latter. Solenoid valve 32, 33 defines a variable leak from exhaust line 31. Valves 51, 61 may be as disclosed in Specification 1,174,243. In a modification, the control and feedback pressures are generated by self-lapping valves operated directly.

Title: A method of determining the fat content of milk and related products
IPC: G01N33/04
Filed: 1963-08-07
Abstract: 1, 059, 825. Photo-electric determination of fat content. N. FOSS ELECTRIC A/S. Aug. 7, 1963 [Aug. 14, 1962], No. 31218/63. Heading G1A. [Also in Division G2] To determine the fat content of a milk sample the sample is heated, diluted with an aqueous solution including a protein dissolving substance, and, either before or after dilution, pressure homogenized. The sample so prepared is passed to the cuvette of a photo-electric inspection device in which light of 0À6 Á wavelength is directed through it. The effective cell size and its spacing from the cuvette are so chosen that the system output as a function of homogenization pressure shows a distinct minimum at the homogenization pressure used. In a first embodiment the milk sample is drawn from bottle 1 through filter 3 and heating coil 4 to heated homogenizing pump 11. From the homogenizer it is fed to a T-connection and on through a tube 15, holding a predetermined quantity, to waste. After any residue of previous samples has been washed out and the tube 15 is full the sample feed is stopped, funnel 20 is moved under its end, and dispenser 16 operated to eject the measured quantity into the funnel followed by a predetermined quantity of diluent containing protein dissolving substance. The force of ejection results in mixing in the funnel and on the return of the funnel to its normal position outlet closure 21 is lifted to allow the prepared sample to flow to cuvette 26. Light from source 28 is collimated at 29 and is directed on to the cuvette through filter 32. Light passing through the filled cuvette enters an internally blackened spacing tube at the end of which is positioned a photo-sensitive cell 30. A distance of 70% of the diameter of the photocell between cuvette and cell is suggested in conjunction with a homogenizing pressure of about 100Kg/cm<SP>2</SP>. The photo-cell output may be applied directly to a meter calibrated in percentage fat. In a second embodiment, Fig. 2 (not shown), a more portable apparatus in which the milk sample is diluted before homogenization is described.

Filed: 1973-07-02
Abstract: 1434653 Feeding sheets LICENTIA PATENT - VERWALTUNGS - GmbH 2 July 1973 [31 July 1972] 31350/73 Heading B8R To regularize the arrival of sheets at the outlet 5 of a conveyer system the separator 1 is arranged to forward the sheets selectively into an empty one of a plurality of channels (3 and 4) and retractable stops (50 and 51) in the channels are arranged to release the sheets to provide a regular spacing between then at the outlet. A photo-cell 60, 61 is associated with each channel and is connected to a control circuit which actuates a deflector 2 to direct an oncoming sheet to an empty channel. If both channels are full the separator 1 is disabled by cutting off the suction to trough 24 by means of electromagnetic valve 28. The control circuit may be set to raise stops 50 and 51 in a sequence to provide an even flow of sheets or may be set to present a single sheet at the outlet 5 in response to an external call-up signal. If the external "callup" signals are infrequent the sheets are taken from a single channel. Suction devices 25 prevent separation of more than one sheet. In an alternative form (Fig. 5, not shown) there are three conveying channels to which sheets are selectively directed by two deflectors (10 and 11). A control circuit directs separated sheets to empty channels and operates the strips (106, 107 and 108) in sequence to provide an evenly spaced succession of sheets at the outlet. To prevent "double feed" a second suction separator having a vacuum chamber 82, Fig. 3, may follow the first. A "double sheet" is bolted by a stop 85 whilst the set of suction apertures in belt 80 which caused separation of the "double sheet" passes around detour roller 86. Arrival of these apertures at the chamber 82 and retraction of stop 85 separates the topmost sheet from the "double". A photo-cell 88 is effective to prevent further separation if a sheet is present at the stop 85 during the interval where no sheet should be present. In a further embodiment, Fig. 8, a single suction belt 207 cooperates with two vacuum chambers 204 and 205 to provide separation from two piles. The separated sheets are directed by deflectors 230 to an empty one of three conveying channels 16, 17 and 18 where their further progress is controlled by stops 232, 233 and 234 as before. The sheet stops may be associated with acceleration rollers, e.g. 52 and 53, Fig. 1, which press the conveyer belts against the sheet as the stop is retracted.

A travelling milling machine for cleaning billets comprises a rocker-arm 5 pivotally mounted at one end of the machine, and at least two rows of milling cutters at the other end of the arm. The cutters are rotated, in the directions shown in Fig. 1, by a motor 4 through gearing 21, 24. The pivot 6, Figs. 1 and 2, is carried by a vertically adjustable slide 34 on a transverse slide 7. The machine is mounted on driven wheels 14, 15 running on rails 25, and further driving wheels engage toothed racks 16. A jack 13 can raise the cutters clear of the work. The depth of cut is determined by vertical adjustment of a roller 10 which rests on the work and holds it down. At the end of a traverse, the roller 10 runs on to inclined guides 17 and raises the cutters. The roller may be replaced by a pressure shoe in which cutters may be mounted. The sets of cutters may be set at an angle as in Fig. 4, and the cutters may be of file-type mounted on rubber rings to allow the machining of uneven surfaces. In a modification, the milling spindles are vertical and the cutters are disposed to cover the whole surface of a sheet to be milled. Each cutter may be driven by a separate motor. The cutters may be adjusted vertically by screws and the rocker-arm may be weighted down by ballast or fluid. The milling spindle 45, Fig. 8, may be mounted to be urged axially downwards by a spring 49, adjusted by a ring 50 operated by an hydraulic or electric motor. A fluid device 56 can be operated automatically to raise the cutter by way of a lever 52. The cutter is mounted by way of a rubber ring 51 or a ball-joint to allow it to tilt on uneven surfaces, or it may be mounted at an angle of 5 degrees to 10 degrees to the work surface. Alternatively, the spindle may be adjusted about a pivot 58, Fig. 7, by a fluid device 60 so that the cutters may be tilted to cut in each direction of traverse.

Abstract: 153,578. Denoel, J. Nov. 6, 1919, [Convention date]. Ruling-machines.- Apparatus for testing the degree of sizing of paper comprises a number of tracers 5 the jaws of which are adjustable for ruling ink lines of graduated thickness ¢ to 2“ millimeters, for example, on the paper to be tested. A table 17 carrying the paper is traversed by means of a spring drum 22. The movement of the table is controlled by arms or fans acting as a brake or governor and mounted on a shaft carrying a gear wheel 29, geared to a rack 24 on the table through gears 28, 27, 26, 25. A ratchet 32 serves to cut out the gearing to the arms or fans when the table is drawn outwards by the handle 23. The tracers are pivoted on a spindle 3 and carry adjustable weights 9 and depending arms 12. A bar 11 carried by arms 10 keyed to the spindle 3, when engaged bv the handle 23 at the end of the return travel of the table, lifts the tracers off the paper. An arm 13, also keyed on the spindle 3, carries a spring catch 15 which, by engaging a notch in a fixed sector 16, holds the tracers in inoperative position. Stops 37, 38, limit the traverse of the table. In operation, if, for example, the back of the paper remains white under the fourth line and is stained under the fifth line, the degree of sizing is given at 4/5 for a specified thickness of paper and a comparable formula may be obtained by dividing this value by, say, the weight of paper per square meter. The testing may be carried out by a single adjustable tracer, or pens may be used, and the table may be fixed and the tracers reciprocated by the mechanism used for the table.
