Title: Process for the extraction of elastase
Inventor: THUILLIER YVONNE
IPC: A61K38/00
Filed: 1963-10-10
Abstract: Elastase is obtained from defatted pancreas by extraction with sodium acetate-acetic acid buffer at pH 4.8 to 5 followed by precipitation with (NH4)2SO4 at 48 to 55% saturation.  The precipitate is resuspended in sodium acetate-acetic acid buffer and, after demineralization, e.g. by dialysis, it is fractionally precipitated from a water-miscible alcohol/water mixture. The active precipitate is recovered, cold-centrifuged, redissolved in sodium acetate-acetic acid buffer at pH 4.7 to 5 and the solution lyophilized. All operations are carried out at a temperature below 5 DEG C.ALSO:Elastase is obtained from defatted pancreas by extraction with sodium acetate-acetic acid buffer at pH 4.8 to 5 followed by precipitation with (NH4)2SO4 at 48 to 55% saturation.

Abstract: 1360444 Colour television SONY CORP 31 Aug 1971 [1 Sept 1970] 40590/71 Heading H4F The colour television camera described in Specification 1,328,411 is modified in that the switched inversion of successive line outputs of signals supplied to synchronous colour detectors is effected to the chrominance and not to the index signal. The arrangement is stated to reduce interference patterns in the form of vertical bands due to a carrier component of the chrominance signal. Fig. 10 illustrates a further modification in which the index signal is obtained by superimposing on the video signal an output due to illuminating the camera tube in successive vertical flyback periods with red and cyan light from xenon tubes 176R, 176C. In this embodiment the delay provided by circuit 181 is one field period. Reference has been directed by the Comptroller to Specification 1,322,520.

Abstract: 1,100,390. Selective printing. BORG-WARNER CORPORATION. 28 Sept., 1965 [14 Oct., 1964], No. 41235/65. Headings B6C and B6F. In an arrangement for selectively depositing character-shaped electrostatic images on a carrier for subsequent development, a mask carrying a plurality of character-shaped apertures is moved adjacent the carrier until the desired character aperture is adjacent the position on the carrier where the charge is to be deposited and a cloud of electrically charged particles is discharged through the aperture to image the carrier. In one embodiment, Fig. 2, a cylindrical mask 30 carrying rows of characters passes between rows of charge heads 51 and a carrier web (not shown) to be imaged. Each row of apertures also carries a row of holes 54 indicative of the binary code of the character identity and illuminated by lamps 56 to energize photocells 58 whereby the letters opposite the charge heads at any instant are identified within the control circuitry. Apertures 55 provide synchronizing signals read by a magnetic pick-up 64. Control circuitry in response to an information signal input and the signals from 58 and 63 selects the exact moments to energize the individual charge heads 51. In a modification, Fig. 5, the mask 90 is in the form of a band carrying a single row of character apertures, Fig. 6 (not shown). The band also carries a series of identical slots whose position is related to the positions of the character apertures, and a further single synchronizing slot. These slots are read by head 96 and counting mechanism in the control circuitry determines, in conjunction with input information indicative of the character to be printed, the instants at which the various discharge heads 51 are to be energized. The band 90 may be replaced by a rotary disc, Fig. 7 (not shown). The web may be guided at the imaging point by an anvil and suitable biasing arrangements for the charge head, mask and anvil are indicated. Suitable field shaping electrodes may be provided near the charge heads.

In a direct-viewing storage tube such as described in Specification 758,677 or 780,391 the conductive storage matrix 27 of the storage grid is formed as a metal plate having a regular pattern of apertures within each of which is deposited a peripheral lining of secondaryemissive dielectric storage material. The conductive matrix acts as a secondary electron collector in place of the separate grid of the above Specifications. A bombardment induced conductivity effect may also be present. The conductive matrix is preferably proud of the dielectric material on the gun side of the grid. The dielectric material, e.g. talc, is applied by spraying while forcing air through the interstices of the grid and then removed from each face of the grid by abrasion. The tube may have one gun only both for viewing and writing, the transition between the two conditions being achieved by a set of ganged two-way switches in circuit with the various electrodes. In viewing the deflection energy is reduced, while the beam is defocused either deliberately or as a result of the change in the gun condiconditions during viewing.
