Title: Controlled degradation of phosphoric acid links in deoxyribose nucleic acid
Inventor: FRIEDMAN ORRIE MAX
IPC: C07H1/00
Filed: 1961-10-18
Abstract: Controlled degradation of some of the phosphoric acid links of deoxyribose nucleic acid (D.N.A.), some of the phosphoric acid links of which are in the salt form and the remainder of which are in the acid form, is effected by reacting with an alkylating or acylating agent in order to convert either the free phosphoric acid links or the links in salt form into fully esterified phosphoric acid links and subjecting the product so obtained to hydrolysis under mild conditions, whereby cleavage takes place at the fully esterified phosphoric acid links Alkylating agents containing the diazo group convert the secondary phosphate esters in the acid form without altering those in the salt form, while sulphuric ester alkylating agents convert the salt form, leaving the free acids unaltered.  The preferred embodiment, in the example, employs a diazo compound, e.g. phenyl diazomethane, or especially diazomethane. The hydrolysis may be effected in either acidic or alkaline aqueous medium, neutral conditions at 80-100 DEG  C. being preferred. A diagrammatic reaction scheme is given showing the use of diazomethane.  The fragments contain both ribosides and ribolides.

Fig. 5 shows a machine in which bending tools 16, 18, 19 are reciprocated by mechanism such as cams 13, 14 on shaft 12. Material 7 for forming a link is fed from either side of a mandrel 17 by operation of a reciprocating gripper 32 and fixed gripper 35, being sheared to length by tools 40 after indenting by tools 37. The reciprocating gripper 32 together with straightening rolls 30 is mounted on a member 25 reciprocable by follower 24 in a track on cam 15. The arrangement may be such that both feed devices are operated alternately by the one cam 15 and follower 24, or the two feed devices may be operated by separate cams and followers if a simple alternating sequence is not desired. In another embodiment, Fig. 4 (not shown), reciprocation of member 25 is arranged to dispense pre-cut lengths of wire from two stores alternately, or again the two stores may be separately controlled to provide other than an alternating sequence. In a further embodiment, two wire delivery devices are movable relative to a link forming unit so as to supply it in desired sequence with different materials, or one delivery device is in line with the link forming unit, and the other produces cut lengths which are moved transversely to their length prior to being fed to the unit. In another embodiment, the shape of successive links is varied by the use of alternative displaceable mandrels, e.g. by the inclusion of a link with rounded side limbs which can be distorted under undue tension loads on the chain.

Abstract: 1,198,118. Removing lint from weaving looms. PARKS-CRAMER CO. 17 Aug., 1967 [23 Aug., 1966], No. 37893/67. Heading F4X. Apparatus removing lint from looms, ceilings and floors in weaving sheds comprises a plurality of blowing units arranged over the looms and traversed along each bay of the shed, the units being oscillated transversely of the looms as they are traversed so that the air streams over adjacent looms do not interfere with each other. The looms 10 are arranged in rows and units 30 are suspended above each row from a bridge 20. The bridge is traversed along rails 21, 22 by a reversible motor. During forward travel at a relatively slow speed air from a blower 37 issues from outlets 38 of the units 30 and a cam and lever mechanism (44, 48, Fig. 4) oscillates one of the units while links 40 ensure that all the units oscillate in synchronism. In a modification a separate motor (55, Fig. 8) crank disc (56) and connecting rod (58) replace the cam 44 for oscillating the units 30. At the end of the forward traverse a limit shaft (73, Fig. 8) engages a stop and the motor is reversed. The reverse traverse of the bridge is made at a faster speed and air is supplied to nozzles 60 directed towards the ceiling and is cut off from the units 30. A linkage connected to the limit shaft changes over a valve in the air supply to the units 30 and nozzles 60 when the limit shaft engages a stop at either end of the travel of the bridge. The nozzles 60 rotate as the air issues therefrom. The lint blown from the looms and ceilings collects on the floor and is removed by a suction head 85 suspended from the bridge and traversing the aisles 15-19. Suction is applied to the heads 85 during both forward and reverse travel.

Abstract: 1,100,360. Inking-apparatus for printing press. NATIONAL CASH REGISTER CO. 24 Aug., 1966 [23 Oct., 1965], No. 37963/66. Heading B6C. Printing apparatus comprises a porous printing member which reciprocates vertically between non-printing and printing positions, an ink reservoir; a common reciprocating support member directly connected to the reservoir and the porous printing member; and a control device permitting flow of ink from the reservoir to the porous printing member during the reciprocating movements of the latter and preventing flow of ink when in the non-printing position. Fig. 2 is a cross-section illustrating the apparatus in which an ink reservoir 10 composed of a liquid-tight container 16, a gasket 20 and a lid 18 is positioned between a frame 12 and a platen 14. The lowest portion 24 of the container 16 carries a capillary porous printing member 26, which is brought into contact with the material to be printed upon, 32, whenever the solenoid 28 is energized. The solenoid 28 has an operating plunger 66 which is connected to a threaded rod 30 and then to the reservoir 10 and the printing member 26. A U-shaped member 36 remains fixed to the frame 12 and assists in transferring ink 46 to the printing member 26 while the reservoir 10 moves up and down. A recess 48 in the lower portion 24 of the reservoir is provided with a plurality of spaced apertures each having a capillary passage 52 in a bushing 50 sealed therein; a fine gauge screen 54 is secured against the lower ends of the passages 52 and rests on top of the printing member 26; the upper ends of the passages 52 may be similarly secured by a gauge 56. When the device is idle, as in Fig. 2, local flat areas 58 in the bridge 42, which forms part of fixed U-shaped member 36, press on the screen 56. effectively sealing the ink 46 in the reservoir from the pad 26. When the solenoid 28 is energized, the reservoir 10 is pushed towards the platen 14, the screen 56 moves away from bridge 42 and ink flows under gravity through passages 52 to the printing member 26; when the solenoid is de-energized, a spring 62 returns the plunger 30 and reservoir 10 to the idle position. In returning to this position the screen 56 is squeezed by the flat areas 58 on the fixed bridge 42 thus ejecting ink again through the passages 52 to the pad 26, before an effective seal is remade.

Filed: 1929-12-12
Abstract: Yarns, fabrics, &c. made of or containing organic derivatives of cellulose, such as cellulose acetate or other cellulose esters or cellulose ethers, are delustred by precipitating zinc sulphide therein.  For example, the materials may be treated with a solution of a zinc salt e.g. chloride or sulphate followed by treatment with a solution of alkali sulphide or of hydrogen sulphide in the presence or absence of acid provided the acidity is not such as to inhibit precipitation of zinc sulphide.  The zinc salt solution may be such as to constitute a swelling agent for the cellulose derivative, or the treatment may be effected in presence of other swelling agents, e.g. formic acid, acetic acid, acetone, &c.  The materials may be saponified before or after the application of the zinc radicle, e.g. as in Specifications 316,521 and 318,468, [both in Class 2 (ii), Cellulose &c.].  In examples, cellulose acetate fabric is padded in a bath of 320 parts of zinc chloride and 750 parts of water, with or without formic acid, at a temperature of 70 DEG  C.; the padded fabric is allowed to stand over night, and is then padded with a 2 per cent solution of sodium sulphide.  The cellulose derivative materials may be associated with other fibres, e.g., cotton, cellulose, artificial silk, wool, silk, &c.
