Abstract: ABSTRACT       The invention provides a method of and an apparatus for making a casting from a mass of dry particulate material and a liquid which co-acts with the dry material.  It is particularly, though not exclusively, concerned with the production of concrete castings.  In the method negative pressure is applied over a first portion of the surface of the dry particulate material, e.g. over one side of the material, and liquid is distributed over a second portion of that surface, e.g. over the opposite side of the dry material. The negative pressure causes the particulate material to be compacted and draws the liquid into the particulate material.

The switched mode power supply circuit, which is connectable to a direct voltage source, comprises a series arrangement of a first switch, a first inductor and a supply capacitor.  The line deflection circuit comprises a series ar-rangement of a second switch and a second inductor and a line deflection coil.  The first switch is adapted to be switched under the control of a first control signal at a frequency which is in integral harmonic relation to the line frequency to pro-duce a charge on the supply capacitor which when charged acts as a second direct voltage supply source for the line deflection circuit.  The second switch is adapted to be switched under the control of a second control signal at a line frequency to pro-vide a deflection current to the line deflection coil during scan periods and to be non-conducting during flyback periods and the second inductor is tuned to a first frequency such that the period is substantially equal to twice the flyback period.  The circuit arrangement is characterized in that the first inductor is tuned to a predetermined second frequency such that the period is substantially equal to twice the non-conducting time of the first switch, whilst the first and second inductors are inductively loosely coupled.  The first switch and the second switch a asynchronously switchable.

Title: Nephelometer having means semiautomatically cancelling components from scattering by particles smaller or larger than those of interest
Inventor: RODRIGUEZ RODOLFO R

Filed: 1975-11-17
Granted: 1979-02-06
Abstract: ABSTRACT OF THE DISCLOSURE           An improved nephelometer for immunochemical complex assay measures forward light scatter in samples.  The angle of forward scatter, about 30°, is small enough to result in a large amount of forward scatter from the immunochemical complex particles which are to be assayed, whose size is of the order of the wave length of the light used in the optical system.          Forward scattering from smaller particles, such as from mole-cules of buffer, antibody and serum, is constant during the course of a test, and is compensated for by the use of subtraction cir-cuits which are readily and semiautomatically adjusted to sub-tract proper values, in accordance with the readings taken on standard or "blank" samples of buffer, antibody and serum.  For-ward scattering from large particles, such as dust, is variable, and results in fluctuating signals, which are electrically pro-cessed to ignore the spurious peaks.  The results of a test are displayed on a digital read out meter.         Also described is a method of and protocol for immuno-chemical assay, whereby the amount of antigen originally present in a sample is determined by adding a known amount of antibody, and by assaying the "blank" component ingredients and the result-ing mixture.

Abstract: Abstract of the Disclosure An electromagnetic relay comprises a coil bobbin of plastic material defining a protective tube, a contact chamber and a magnet chamber which together form a space that extends the entire length of the bobbin and is initially open at both ends.  A permanent magnet is disposed in the magnet chamber, serving to seal one end of the space.  This magnet has a surface exposed to the contact chamber and is made of a material activatable as a getter.  A contact actuator is mounted to extend along the protective tube with a free end extending into the contact chamber.  A pair of pole shoes each have a first end in proximity to the permanent magnet and a second end extending into the contact chamber.  These second ends form fixed contacts for cooperation with the free end of the contact actuator.  After assembly of these parts the space is subjected to a vacuum and an elevated temperature to drive off moisture and activate the getter.          The vacuum is then replaced with an atmosphere of a protective gas, and the other end of the space is sealed with a closure.

Abstract: Abstract of the Disclosure A data writing and recording system and method and circuitry therefor is disclosed in which peak shift due to pulse crowding of data recorded on a magnetic medium is sub-stantially reduced. The recorded data time pattern is pre-emphasized to compensate for peak shift such that an optimum magnetic pattern is recorded on the magnetic medium.  The preemphasis of recorded peak shift errors is accomplished either by delaying or advancing the time when a particular peak shifted data transition caused by a known encoding data pattern will occur.  NRZI type encoded data is coupled to a first serial to parallel shift register and clocked through to a ROM at a frequency corresponding to the data bit cell width.  The ROM examines the incoming data, which is also clocked from an intermediate stage in the first shift register to a second serial-to-parallel shift register hav-ing a data clock frequency substantially greater than the data clock frequency of the first shift register.  The second shift register operates as a multi-tapped delay line having a multiplexed output selected by a look-up table programmed into the ROM in accordance with a determination by the ROM of the degree incoming peak shift and the amount of compen-sation required.  Thus, data is either delayed or advanced before it is written, thereby compensating for peak shift error which would otherwise be present in the recorded data.
