Title: Improvements in or relating to the Measurement of the Properties of Fluids
Inventor: REFSON BERNARD HENRY
IPC: B01L3/00
Filed: 1968-04-24
Abstract: 1,196,374. Photo-electric testing. WESTONMARLOW INSTRUMENTS Ltd. April 24, 1968 No. 19378/68. Heading G1A. [Also in Divisions B1, G2] In order to measure a property of a fluid, a sample of the fluid is introduced into a flexible cell, the quantity of the sample being insufficient to fully distend the cell, and the cell is then flattened between a pair of opposed rigid surfaces, so that a predetermined thickness of the fluid is formed in the cell and can be submitted to the required measurement. Fig. 3 shows a series of cells 34, to 44 made by joining two sheets of flexible plasticised polyvinylchloride along lines 45 by heat sealing, adhesive or preferably highfrequency welding. A sample of the fluid is introduced into the open top of each cell, and the tops are then secured by clamping the top edges between two rigid strips 46, 48. One end of the loaded package is introudced into the tapering gap between the faces of two rigid blocks 8, 10, of P.V.C. or polytetrafluoroethylene; and the package is drawn into position so that one of the cells, e.g. 42, is flattened between window 18 in block 10 and a corresponding window in block 8. When used as a spectrophotometer, radiation from a tungsten filament lamp directed through window 18, is transmitted through the fluid in the flattened cell, and emerges through the window in block 8 to be received by a suitable detector and recorder. Filters are provided to select the desired wavelength for study. In order to measure the conductivity of a fluid, the windows in blocks 8, 10 are replaced by electrodes; and the impedance between them is measured at two frequencies. Also described is an apparatus for taking fluorometric measurements. The cells may be made of polyethylene, polypropylene, polychlorotrifluoroethylene, or aluminium foil.

Filed: 1933-07-14
Abstract: 420,696. Saddles. JELLEY, H., and JELLEY, J., Drilastic Works, Warwick Road, Tyseley, Birmingham. July 14, 1933, Nos. 19915/33 and 3068/34. [Class 136 (iii)] The weight-supporting part of a cycle &c. saddle is composed of one or more units each consisting of an integral combination of a nose-piece attachment web d, a plurality of extensible substantially parallel elastic cords b, an intermediate web e, a plurality of extensible fan-wise disposed elastic cords a and a cantle-plate attachment web c. The cords b are preferably thicker than the cords a to give them a similar load-sustaining capacity, and the inner cords of either or both groups may be thicker than the outer cords. The cords may be round or oval in cross-section, and where they join the webs may be reduced in thickness and increased in width. The units may be die-moulded and vulcanized, and the webs c and d may be re-inforced locally with canvas, &c. An arch-shaped spring-former may be fitted in a groove in the upper side of the web e to bring it to a desired shape. Two or more separately-moulded multi-cord units may be employed, extending each from the nose-piece to the cantle-plate, the front and intermediate webs being optionally moulded to a permanent curve to avoid the necessity for a former. Tensioning means on the nosepiece enables the flexibility of the saddle to be adjusted. An independent seating of moulded rubber, with or without fabric re-inforcements, leather, or other flexible material may be clipped detachably to the saddle underframe.

Abstract: 994,211. Cam-operated switches. S. SMITH & SONS (ENGLAND) Ltd. Sept. 8, 1961 [June 9, 1960], No. 20305/60. Heading H2B. A time delay switch for controlling a spin drier &c. whose lid must not be opened while the drive motor is energized, comprises a lever 4 locked on a spindle 2 driven by a timer (not shown) and a cam 11 loose on the spindle 2 and moving with the said lid both acting on a switch operating member 8 spring-biased to its open position but normally displaced to its closed position by engagement with an abutment 6 on the lever 4. The drier is started by first opening the lid causing cam 11 to be rotated anti-clockwise, an axial projection 13 thereon engaging a second abutment 7 to rotate the lever 4 and thus wind the timer. Member 8 remains in the open position, since a projection 12 thereon now engages a rise 20 on cam 11, until the lid is closed, returning cam 11 to the position shown, allowing the switch to close and lever 4 becoming free to move under the action of the timer. One gear in the timing chain has a few teeth missing so that lever 4 is released near its rest position to which it rapidly returns, abutment 6 opening tho switch. If the lid is opened before completion of the timing period cam 11 rotates so that rise 20 opens the switch, stopping the motor, while projection 13 restores lever 4 to rewind the timer.

Abstract: 247,842. Suchorzynski, A. von. Aug. 13, 1925. Hearing-appliances - A metal diaphragm 1, Fig. 1, mounted in a rubber shell 2 fitting the concha of the ear, is connected by a spiral spring 3 having a looped end 4 to a membrane bag 5 bearing against the tympanum. In a modification the spring 3 is covered by a soft rubber tube, which thereby assumes a corrugated form. The tube may be integral with the bag 5. The spring may be oval to conform to the auditory canal. In a modification the vibrations are communicated from the diaphragm to the membrane bag through a body of liquid. The appliance shows in Fig. 5 comprises a glass vessel 2 fitting the concha, provided with a metal ring 8 in which is fitted a cone 9 and a diaphragm 10. The cone 9 is provided on the outside with a diaphragm 13, clamped by a cap 12, and connected by a pin 14 with a conical rubber diaphragm 16, clamped with a wire gauze cover 17 in a ring 15. The bulb 2 is connected by a tube 19 to the membrane bag bearing against the tympanum. The spaces within the bulb 2 and cone 9 are filled with water, oil or other liquid, air bubbles 20, 21 being preferably left to provide elasticity. It is stated that owing to the different sizes of the diaphragms 16, 13, 10 amplification of the vibrations according to the principle of the hydraulic press is produced. The tube 19 is preferably slightly narrower than the auditory canal so as to leave an air space. A wire spiral may be mounted within the tube 19.
