Title: Particle analyzing method and apparatus employing multiple apertures and multiple channels per aperture
IPC: G01N15/12
Filed: 1970-05-11
Abstract: 1311213 Particle analyzing systems COULTER ELECTRONICS Ltd 11 May 1970 [12 May 1969] 22657/70 Heading G1N In a Coulter counter type particle analyzing system the output signals each representing the volume of an individual particle passing through a passage way are applied to a plurality of logically parallel electrical channels each being responsive to a different subrange of particle size. The particle volume for each channel is accumulated over a specific period of time and multiplied by the reciprocal of the time to obtain the total particle volume per unit time for each channel. Figs.1A and 1B, show the three channels associated with one of the passageways or apertures 10 there being six apertures associated with a total of twenty five channels. The subrange of particle size of each channel is determined by threshold circuits 18, 19, 20, 21 having average volume changes from channel to channel of factor 2 connected in pairs to veto logic circuits 22, 23, 24. After passing through AND gates 28, 29, 30 and capacltive pump circuits 31, 32, 33, Fig.5, (not shown), information is accumulated in integrators 35, 36, 37 representing volume of particulate matter for each channel, the period of accumulation being determined by control binary 45 and AND gates 28, 29, 30. The integrator outputs are then applied to one input of multipliers 80, 81, 82 to the other input of which is fed a signal from integrator 76 and reciprocal computer 79 representing reciprocal of the period of accumulation. The period of charge of integrator 76 from D.C. reference source 74 which also controls the pump circuits 31, 32, 33 is controlled by switch 77 operated by the control binary 45 at the end of the count. The arrangement continues counting until some predetermined number of particles is counted on one of the channels of the aperture unless halted prematurely by approaching saturation of any integrator or at a predetermined time as set by threshold circuit 99 or upon the arrival of a pulse via line 67 indicating a pluggage in the aperture. The outputs from the multipliers are fed to a summing matrix 92 and curve generator 93. The plural apertures are of the type shown in Specification 1166287.

Mandrels 1 wound with pile yarn 2 are assembled side by side by means of projections 5 engaging holes in supports 6, and a backing 3 of rubber composition containing a blowing agent is applied and heated; the coils of yarn are then cut after withdrawing the mandrels or by running knives along grooves 4 in the mandrels. An adhesive may be applied to the yarns before the backing is applied. The mandrels may have a groove at the side to which the backing is applied, into which the composition penetrates to anchor the tufts more securely; strips of rubber composition may be laid in the grooves before winding with yarn. Fabrics may be made face-to-face by applying a backing to both sides of the mandrel assembly and cutting through the middle; the mandrels may consist of pairs of rods (which may be flat on their adjacent sides) having a gap between them for passage of the knife. The vulcanizing and blowing may be effected between heated platens, spaced to determine the thickness of the expanded backing. In a continuous process, the assembly may be led to the platens between wire mesh belts. The backing composition may be applied in sheet form or as a paste. A further backing of hessian may be applied before heating. Specification 917,523 is referred to.

Title: Improvements in processes for producing piezo-electric crystals
IPC: C30B7/00
Filed: 1946-08-02
Abstract: <PICT:0643448/III/1> <PICT:0643448/III/2> <PICT:0643448/III/3> A monocrystalline body is made by mixing powdered silica, tourmaline, or Rochelle salt with a small proportion of a liquid capable of slightly dissolving the powder, compressing the mixture so that it behaves as a rigid body, and subjecting the compressed mixture to high-frequency vibrations.  The vibrations are set up by an alternating electric field and/or by a source of supersonic oscillations.  One frequency component is made equal to the natural mechanical vibration frequency of the compressed body. The process is preferably carried out at an elevated temperature below the melting point of the substance, and in the presence of a crystallization catalyst.  Oriented growth may be superimposed upon a piezoelectric monocrystalline body, such as an oscillator plate, by means of the process; in this case a mixture of the finely-divided substance of the plate and the solvent, is packed around the plate, the combination is then compressed so that it behaves as a rigid body which is placed in an alternating electric field.  Quartz, chalcedony, hydrated silica, or amorphous silica in the form of particles of 10 micron size is mixed with a small amount of water; and a small amount of a metallic hydroxide or of a strong organic base, is added as catalyst.  The mixture is packed into a compartment, Fig. 1, consisting of glass or ceramic walls 11, with top and bottom electrode plates 1, 2.  The temperature is raised to about 374 DEG  C. by resistance heaters 14, pressure is applied to the top electrode by means of shaft 15, and an alternating electric field of frequency between 50,000 and 10,000,000 cycles per second, is maintained between the electrodes by oscillator A and conductors 19.  In the modification shown in Fig. 6, electrodes 3 and 4 provide an inclined H.F. field through the mass, and the ends 18 are connected to a source of supersonic oscillations B (15 to 50 kilocycles/sec.).  Fig. 8 shows the arrangement used to build up a quartz oscillator plate 23; it is packed in a mixture 22 of powdered silica, water and catalyst.
