Title: Unitized solid phase immunoassay kit and method
IPC: G01N33/545
Filed: 1975-10-29
Abstract: 1488532 Antibody or antigen immunoassay MONSANTO CO 29 Oct 1975 [30 Oct 1974] 44701/75 Heading G1B A component of an antigen-antibody reaction is immunoassayed by a process comprising coating and binding one of the components to at least a part of the surface within a receptacle capable of binding said component and contacting the surface with the other component in labelled form so as to disperse it, but not to bind it, over the surface and thence contacting the surface with a sample solution containing one of the components thereby producing a two phase system and causing interaction between the components with indirect bonding of the labelled component to the surface, separating the phases and thence measuring the labelled content of one of the phases which is a function of the concentration of the component in the sample solution Preferred assays are those in which the antibodies are antidigoxin and digoxin is determined, anti-cyclic adenosine monophosphate and cyclic adenpsine monophosphate is determined and antihuman growth hormone and human growth hormone is determined. A means for use in the immunoassay of a component of antigen-antibody reaction comprises a surface within a receptacle to at least a part of which one of the components in solid form is bound and in proximity to which the other component is present in labelled and in solid form but not bound. The receptacle may comprise a test tube with a plastic polymeric surface e.g. a polyolefinic or a polystyrene surface. The unbound component can be labelled radioactively, enzymatically or fluorescently.

Title: Fluid flow measurement method
IPC: G21H5/02

Abstract: 963,563. Fluid flow rate measurements. CALIFORNIA RESEARCH CORPORATION. Nov. 26, 1962 [Dec. 1, 1961], No. 44702/62. Headings G1A and G1R. The invention relates to a method of determining the volume flow rate of a fluid stream, which comprises measuring the radio-activity of a quantity of radio-active material in counts/unit time, C, as detected by a radio-activity counter, introducing the said quantity of radio-active material into the fluid stream, withdrawing a sample of the fluid from the stream at a point downstream from the point of introduction of the radio-active material, the withdrawal being at a constant rate and continuing for a time T, which includes the time during which the introduced material in the fluid passes the withdrawal point, determining with a radio-activity counter the number of counts per unit time/ unit volume, R, of the sample, the counter having a corrected response equivalent to that of the first mentioned counter, and determining the volume flow rate Q of the fluid stream according to the formula Q = C/RT. Any suitable type of radiation counter may be used as a geiger counter, or proportional counter or either crystal or liquid scintillation counters. The counter used in measuring the radio-activity of the quantity of radio-active material is preferably used also for investigating the withdrawn sample. Suitable radio-active materials which may be used are cesium-134, cesium- 137, gold-198, antimony-124, cobalt-60, krypton-85, iodine-131, tritium and carbon-14.

Title: Filaments
Inventor: BARLOW GEORGE EDWARD
IPC: D02G1/00
Filed: 1964-11-16
Abstract: Artificial filaments of meltspun synthetic linear polymers are passed in a bundle or spread multifilament yarn across a narrow heated surface maintained at 170-270 DEG C, such that the filaments are heated on one side only, their angle of deflection over the narrow surface being less than 45 DEG , and the combination of filament speed, contact angle and width of heater being selected so that a temperature gradient is imparted across the cross-section of the filaments, whereby at least some portions of the filaments acquire a differential shrinkage potential.  The filaments and/or yarns may subsequently be crimped by heating. Specified polymers are polyamides, polyesters and polypropylene and copolymers containing a major proportion thereof.  The filaments may be of solid or hollow circular, trilobal, cruciform, tape or T-shaped cross-section.  The heating may be effected before, during or after any stretching step. Heat-relaxing may be effected before of after wind-up or on staple fibre, or on goods knitted from the multifilament yarn.  In the final yarn, helical crimp may vary randomly, crimped sections may be separated by short straight sections, and the crimps of adjacent filaments are out of register, along the length thereof.

Title: Improved process and apparatus for planning the cutting of sheets of glass
IPC: C03B33/037
Filed: 1962-12-14
Abstract: In a process for determining and executing a glass-cutting plan defining the position of cutting lines on a sheet of glass on which defects have been marked with visible markings, the cutting plan is determined and executed by an operator on a reduced image of the sheet of glass and is recorded, either in correct dimensions on the sheet of glass itself, or on a memory device through the medium of controls operated by the operator.  A glass sheet 1 is supported on rollers 2 and other rollers behind the sheet (not shown) of a conveyer that transports the glass sheet 1 across in the plane of the glass sheet 1 in time with an operator's cabin driven at the same speed.  The operator views the glass sheet 1 through an optical system terminating in an image on a ground glass screen on a desk 6. The operator uses electrical controls to position two rulers 11 (one of which is shown), in accordance with his cutting plan.  One such ruler 11 and a marker 10 are synchronously driven with a suitable multiplication ratio, e.g. 1 to 5, between them, by means of chains 13, 17 driven by suitably geared synchronous motors 14, 15 respectively to enable the cutting plan to be transferred by the marker 10 to the glass sheet <PICT:1023804/C1/1> 1.  The second ruler is similarly controlled. For more accurate marking of the glass sheet 1, the operator uses a control panel 19 for making, either directly through a measuring device 22, an amplifier 25, and relays 26 controlling a synchronous motor 27 and an electric brake 28, or indirectly via a memory device 21, e.g. for a series of windscreens. Other embodiments mentioned include the replacement of the optical system by an electronic system and the recording of the cutting plan on magnetic tape, the signals therefrom being used to actuate cutting machines, conveyers &c.
