Abstract: 1,127,061. Screw-and-nut gearing. KEARNEY & TRECKER CORP. 20 Jan., 1966 [11 June, 1965], No. 2738/66. Heading F2Q. [Also in Division B3] A machine comprises drive means for moving a member along a path, the drive means being actuable also for locking the member in position. Three vertically-adjustable .quills of the machine carry milling-cutters. Each quill is locked in position by rotating nuts 60, 61, fig. 2, in opposite directions on a thread 62 on the quill, so that the nuts engage fixed abutment 54, 56. By releasing the nut 60. and rotating the nut 61 in either direction, the quill can be adjusted axially, the nut 60 also being rotated to keep it free fromÀ re-locking. The nuts are rotated in unison by a shaft 93, 84, meshing pinions 114, 109 and gears 81, 97 meshing with gear-teeth on the nuts. To rotate the nut 60 only, the gear 114 is withdrawn axially by a finger plate 119. To eliminate play of the quill in its bore, a screw 137 can be tightened, by the same tool as is applied to the shaft 93, to force a pad 131 against the quill surface.

[Class 108 (iii).] A shock-absorber particularly for use on vehicles comprises a body member 1 having internal threads which mesh with a corresponding thread on an intermediate member 8 which is threaded internally with threads of a steeper pitch to receive a cylindrical member 9. The member 9 is provided with discs 11, 12 and is free to rotate on a rod 10 which passes through a stuffing- box 4 provided in a screw cap 2 closing the member 1. The threads are reversible and for normal purposes have a pitch angle of about 20‹. 363,207. Shock absorbers. AKTIEBOLAGET SUPERIOR and WESTERBERG, A., 10, Kungstradgardsgatan, Stockholm.-(Assignees of Everstam, E. A. ; 53, Bondegatan, Stockholm.) Feb. 2, 1931, No. 3334. Convention date, Feb. 3, 1930. [Class 108 (iii).] In a hydraulic shock-absorber for automobiles in which at least one cylinder and piston are arranged between the vehicle frame and axle and in which a valve member controls a byepass channel between the cylinder and an outer space the valve means is subjected to the action of forces of inertia at the upward and downward movement of the vehicle axle to introduce liquid under pressure from a container to one side of the piston or pistons, in order to cause the piston or pistons to move in one direction. In one form, pistons 5 having non- return valves 10 reciprocate in cylinders 9. During small relative movements of the frame and axle oil passing the non-return valves 10 is forced past spring-loaded valves 19, 20 into a container 31 formed integral with the shock-absorber casing. The two cylinders are connected by a passage in which an inertia-controlled valve 12 can establish connection through a port 13 between the lower ends of the cylinders and a chamber 14 ; simultaneously a channel 30 is opened to permit oil under pressure to pass from the container 31 to the underside of the pistons the arrangement being such that, when the vehicle wheel enters a depression oil flows from under one piston and oil under pressure is admitted below the other so that the car frame is retained at about its original level, the action being reversed when the wheel passes out of the depression. The valve 12 is under the control of a weighted lever 26 and is normally kept in neutral position by a helical spring 16 and its V-shaped end 17 which engages a dowel 18. The lever 26 may be provided with a spring 34, Fig. 4a, adapted to strike against the'casing and give an upward impulse to the lever. The chamber 31 is provided with a safety valve 32. In amodification the oil under pressure may be supplied by a separate pump and control by the valve 12 may be replaced by separate inertia-controlled valves adapted to separately admit the pressure fluid and control the escape of fluid.

Title: Producing phenolic chelate resins
IPC: C08L61/10
Filed: 1974-01-23
Abstract: 1447451 Phenolic chelate resins UNITIKA Ltd 23 Jan 1974 [23 Jan 1973] 3216/74 Heading C3R  A phenolic chelate resin suitable for adsorbing heavy metal ions is produced by polycondensing an aldehyde and a phenol, at least some but not all the phenolic nuclei having had introduced thereinto a substituent which includes the group >NCH 2 COOH, preferably derived from iminodiacetic acid. The process is preferably carried out by first maintaining an acidic mixture of a phenol, an aldehyde and iminodiacetic acid at a temperature of from 20 to 90 C. to introduce the iminodiacetic acid-containing residues into at least some of the phenolic nuclei, and, after addition, if necessary, of a phenol and/or aldehyde so that unreacted phenol and aldehyde are present, refluxing the reaction mixture at 90-110 C. thereby polycondensing the unreacted phenol, substituted phenol and said aldehyde. An acidic or basic catalyst may be used for the condensation reaction. The molar ratio of the imino-diacetic acid to total phenol is preferably from 0À1-0À9 and the aldehyde/phenol ratio is preferably from 1À1 to 1À5 for a resole type phenolic resin and from 0À7 to 1À1 for a novolak-type phenolic resin. The phenol may be phenol itself, pphenylphenol, bisphenol A, o-, m-, or p-ethylphenol or cresol, various xylenols, resorcinol, catechol or alphanaphthol. The aldehyde may be formaldehyde or a formaldehyde donor such as paraformaldehyde or hexamethylenetetramine, acetaldehyde, propionaldehyde, benzaldehyde or furfural. The selectivity of the resin for heavy metal ions is generally in the order Hg, Cu, Pb, Ni, Cd, Zn, Co, Mn, Ca, Mg, Ba, Sr and Na. The resin containing adsorbed metal ions may be regenerated by treating with a mineral acid, e.g. HCl or H 2 SO 4  and preferably subsequently treating with an aqueous alkaline solution, e.g. NaOH or KOH. In the examples resins are produced by first reacting an aqueous mixture of phenol, formalin and iminodiacetic acid and then either (1) adding further formalin and then dehydrating either in the presence or absence of NaOH and then heat-curing the resin powder produced, or (2) adding further phenol and formalin and then dehydrating and then heat-curing the resin produced using aqueous formalin and HCl, or (3) reacting the mixture with further formalin in the presence of HCl and then with phenol and subsequently dehydrating. The resins produced above are converted to the sodium salt using aqueous NaOH. In another example a resin is produced by first reacting an aqueous mixture of bisphenol A, iminodiacetic acid and formalin, then adding further bisphenol A and formalin and then dehydrating, and heat-curing the resin produced with aqueous formalin and HCl. The resins of the examples were used to adsorb Cd ions.
