Abstract: 1394664 Autoradiography AUSTRALIAN ATOMIC ENERGY COMMISSION 29 July 1969 [1 Aug 1968 16 May 1969] 38100/69 Heading G2X A photographic image is reproduced by treatment so as to induce radio-activity in the image material and then forming an autoradiograph from the image so treated. Prints of varying density and contrast may be obtained from underexposed negatives. Radio-activity may be induced (a) by irradiation with sub-atomic particles, e.g. thermal neutrons, or high energy gamma rays; (b) by chemical reaction of the image material with radio-active elements or their compounds; or (c) by treating image silver material with a solution containing a radio-active silver isotope. The autoradiograph is prepared by pressing the treated emulsion against an unexposed emulsion in a light-tight container. A pre-treatment with a photographic reducer may be given to remove background fog; silver sulphide fog may be cleared with a solution of KCN containing hydroquinone, a solution of thiourea, or a solution of thiogly-  collic acid. In examples (1) the silver image is converted to radio-active silver sulphide, after an optional conversion to silver bromide; (2) polonium-210 is deposited from solution on to the silver image; (3) the negative is treated with a solution containing Ag-110m, Na 2 CO 3 , potassium ferricyanide, and KBr; (4) the silver image is converted to inactive AgI and then exposed to thermal neutrons to form I-128; (5) the silver image is toned with a mixture of uranyl nitrate, potassium ferricyanide and acetic acid, and irradiated with thermal neutrons while forming the print.

Title: Reagents useful in pregnancy-testing and processes for their production
IPC: G01N33/76
Filed: 1961-11-06
Abstract: A composition useful in testing for pregnancy comprises a conjugate of chorionic gonadotropin (CGTH), bis-diazo benzidine p  and red blood cells, e.g. of sheep.  It may be prepared by adding washed sheep erythrocytes to a solution of CGTH, adding thereto a solution of bisdiazo benzidine in phosphate buffer and veronal buffered saline, removing the solid (sensitized cells) and suspending them in a diluent composed of veronal buffered saline containing 1 grm./l. of bovine serum albumin.  The invention further comprises a reagent containing antibodies capable of in vitro complement fixation of human CGTH which is prepared by injecting highly purified (alum precipitated) human CGTH into an animal, bleeding the animal when the antibodies have formed and obtaining the blood serum therefrom.  The above reagents may be used in a pregnancy test wherein urine from the patient is contacted with the antibody-containing serum and the CGTH-bis-diazo benzidine-red blood cells composition is added subsequently.  Urine of a pregnant individual will contain CGTH which will fix the antibody of the serum and addition of the CGTH conjugate will cause no reaction.  Urine from a non-pregnant individual will not contain CGTH so that the antibodies of the serum remain available and will react with the CGTH conjugate and cause agglutination which may be detected visually.  In the test procedure described, the operations are performed on a series of dilutions of the urine and the results are compared with corresponding "blank" dilutions.

In order to reduce breakage of material being discharged from a belt conveyer 29 to a shoot 7, the latter is adapted to be raised or lowered by means responsive to an increase or decrease respectively in the speed of the belt. The shoot 7 is rigid with side plates 1 to which are pivotally connected at 15, side plates 14 carrying a further shoot portion 12. Yet a further shoot portion 11 is carried by side plates 13 which are pivotally connected at 16 to the plates 14 and have slots 28 which engage pins 17 carried by the plates 14. The side plates 1 are connected by bell-cranks 2 to a tie rod 6 which is displaceable in response to change of speed of the conveyer 29. As the speed increases, the shoot portions 11, 12 and 7, are thus rotated about the axis of a spindle 8 to a position (Fig. 2, not shown), in which the portion 11 is below the centre 31 of the conveyer drum 30. If material becomes jammed between the drum 30 and the shoot portion 11, the latter is forced to pivot into the position shown in dotted lines. A follower 21 thus acts on a cam 22 so as to displace one or other of bell-cranks 23, 24, and operate a trip switch 27.
