Title: Cancer associated polypeptide antigen process for its pre paration and composition useful as an immunizing agent
IPC: A61P37/00
Filed: 1973-07-09
Abstract: To obtain a tumour polypeptide antigen, initially material with tumour polypeptide antigenic activity is homogenised in a liquid at a temperature not exceeding 0 DEG C. The solids are removed from the mixture of liquid homogenate and solids directly or after treatment with an organic solvent in the cold. The solids are extracted with an alkaline aqueous solution. The extract is filtered through a filtration gel of the molecular sieve type in bead form which permits fractionation of compounds with a molecular weight in the range from 10,000 to 20 x 10<6>, the gel is eluted and the fraction with a molecular weight of 10 x 10<6> to 20 x 10<6> is obtained. The resulting fraction is purified by chromatography. The fraction having antigenic activity is obtained and subjected to isoelectric precipitation by adding acid until the solubility of the polypeptides reaches a minimum as a consequence of the presence of the polypeptide molecules in the form of zwitterions. Subsequently, the polypeptide antigen is further purified. The resulting tumour polypeptide antigen can be used for the preparation of antibodies which are monospecific for the polypeptide antigen.

Abstract: 429,431. Ink-ribbon mechanism. SMITH & CORONA TYPEWRITERS, Inc., L. C., 701, East Washington Street, Syracuse, New York, U.S.A. Nov. 24, 1933, No. 32909. Convention date, Nov. 29, 1932. [Class 100 (iv)] In apparatus for supplying ink to a ribbon in a typewriter or printing- machine, a non-absorbent rotary roller dipping into an ink - reservoir co - operates with a closely adjacent non- absorbent member, also dipping into the ink-reservoir, to raise a film of ink to a non - absorbent, rotary transfer device which contacts with the upper part of the roller and transfers ink to the ribbon during its traverse in either direction, the roller and transfer device being revoluble in either direction. The apparatus may supply ink directly to the ink ribbon of the machine or an absorbent or non-absorbent conveying-ribbon which is interwound with the ink ribbon. Since the apparatus is non-absorbent it can be employed for supplying a pigment ink. The apparatus shown in Figs. 1 and 4 supplies ink to a narrow conveying-ribbon 50 which is attached at the ends, by means of eyelets, to the ink-ribbon proper 49 and is wound therewith on the spools 10. The apparatus comprises two contiguous rotary rollers 90, 91 for raising a film of ink which is transferred to the conveying-ribbon, as it passes over a pulley 79 driven thereby, by means of a rotary disc 85 having a bevelled, and preferably notched, periphery. The rollers fit closely in cylinders 93, 94 in a reservoir 97, a slot between the cylinders having a bottom port communicating with the reservoir. The reservoir is secured beneath the top plate 53 of the machine and carries grooved guide-pulleys 77 for the conveying-ribbon, the pulley 79, and an adjustable support 82 for the disc 85, the support being secured by a screw 74 passing through a slot 76. A pinion 86 on the disc engages pinions 81, 88 on the pulley 79 and roller 90 respectively. The pinion 88 engages a pinion 89 on the roller 91. The guide-pulleys and disc are arranged in a bay 62 formed by a flange 63 on the top plate. The conveying-ribbon passes through guides each consisting of a pair 64, 65 of superposed channel-plates which are secured by screws 70 to the flange 63, the upper channelplate being detachable to permit of insertion of the conveying-ribbon. In operation, a very thin film of ink is raised by the rollers, and a minute line of ink is deposited by the disc on the conveying-ribbon and is transferred thereby to the ink ribbon. In an alternative arrangement, the cylinders 93, 94 are omitted, and the rollers 90, 91 are arranged in light contact, or a small adjustable space is left between the rollers. Wipers may be arranged to engage the rollers at the level of the disc 85. The rollers may have a covering of vulcanized fibre.

Title: Improvements in machines for the production of wire ropes
IPC: D07B3/08
Filed: 1947-12-16
Abstract: 659,741. Machines for making wire ropes. HOLM, C. J. Dec. 16, 1947, No. 33112. [Class 109] In a machine for the production of wire ropes, the bobbins supplying the wires are mounted on shafts on a bobbin frame, which shafts are inclined to the vertical axis of the machine and converge toward a common point, and the bobbins are suspended in a substantially horizontal plane at a level above or below a twisting mechanism, which latter performs the twisting of the wires about a substantially vertical axis. In the form shown, the bobbins 5, 7 are carried by a stationary annular frame 1 above the stationary twisting head 11 from which the twisted rope is drawn off on to a take-up bobbin 14 mounted on a frame 13 rotating about a vertical axis. The bobbins are rotatably supported in forks at the free ends of rotating shafts 6, 8, the axes of which remain stationary during the twisting operation. The axes of the shafts 6 converge downwardly towards an apex located on the axis of the twisting mechanism substantially at the point 11 at which the twisting operation is performed. The shafts 6 and 8 are rotated by means of belt drives 9, 10 so as to avoid twisting the wires or core about their own axes during the strand-forming operation. 'The bobbin frame 1 is mounted on a circular rail or track 2 by means of rollers 3, so that it may be rotated for changing the position of the bobbin carrying shafts to facilitate 'the substitution of full bobbins for spent ones. A locking device 4 is provided for maintaining the frame 1 in a stationary position during the twisting operation. Strands may be used instead of wires.

Title: Home television receiver modified to operate as video terminal
IPC: G09G1/04
Filed: 1972-07-17
Abstract: 1393604 Video display apparatus RCA CORPORATION 17 July 1972 [30 July 1971] 33361/72 Heading H4T To produce a low cost, readily available video display capable of displaying 960 characters, arranged in 12 rows of 80 each, a mass produced 525 line television receiver is modified by rotating the scan coils through 90 degrees so that a vertical rather than a horizontal raster scan is produced, doubling the line rate to give 960 visible lines and 89 invisible (fly-back) lines, but without decreasing the line flyback period, and increasing the bandwidth of the receiver components to give 120 resolution elements in each vertical line. Each character can thus be displayed as binary brightness modulation of a block of resolution elements 12 wide by 10 deep, 2 width elements and 3 depth elements of these being used as spacing elements. The characters are stored, prior to display in a 12 wide by 20 deep element matrix form, but in the binary read out for each line scan, the 20 elements are grouped in 10 sets of 2 and each set adapted to comprise elements of the same type, i.e. both bright or both dark. The 20 elements are thus effectively converted to 10. The line rate is altered by a change in value of a capacitor (36) (Fig. 5, not shown), in the line oscillator. The line sweep (visible) period is decreased, e.g. from 48 to 16À25 Ásec. but the line fly-back period is kept constant, e.g. at 15À5 Ásec. this makes any change of fly-back E.H.T. transformers &c. unnecessary. In a video display terminal fed by a time shared computer Fig. 6 (not shown), the computer feeds the digital information of the complete 960 character matrix into a random access memory system; the contents of which can be changed by a keyboard "write-in" system. A 12 character column is non-destructively read out of the matrix at a time into a display register and odd lines of the column are fed to the display described above followed by the even lines. When the column has been thus displayed in interlace fashion, the process is repeated for successive columns of characters.
