[Class 65 (i)] In a metal casement window of the type comprising fixed and moving frames having inner and outer cooperating flanges and a stay adjustment having a sliding friction clamp carried by a stay arm, which is fixed to one of the frames,while the clamp slides on a guide fixed to the other frame, the guide consists of a rail which is formed integrally with or united throughout its length as by welding or riveting to the inner flange of the frame and is provided with a retaining rib for the clamp. The swinging arm E of the stay is hinged at one end to a bracket D on the fixed frame A of the window while the other end carries a clamp F which is in sliding engagement with the rib 4 of the guide-bar 1, formed integrally with or attached by welding or riveting to the swinging frame B. The guide bar, which is formed of or provided with a liner of brass &c., may comprise an overhanging or horizontal portion 3 terminating in a rib 4 or may be a strip formed with a laterally projecting rib ; in each case, however, a groove adjacent the rib provides a condensation channel for water. The securing clamp is formed of two parts 6, 7 between which the rib 4 is clamped, and the parts are mounted on a headed stud 9 which is fixed to the arm E, clamping pressure being applied by a wing nut 10. In a modification, in order that the clamping member 10 may not foul the window when operated, the angle of throw is adjustable relatively to the window to obtain the proper setting to permit the full movement to take place, and for this purpose, the stud 9 is formed with a squared portion adapted to engage a groove in the lower half of the clamp, from which it may be disengaged when effecting the preliminary setting. A stop 16 or other projection may limit the movement of the clamp along the bar. The guide bar may be formed integral with the fixed frame of the window.

Title: N-pyridoxyl substituted amines and preparation thereof
IPC: C07D401/12
Filed: 1948-11-16
Abstract: N-Pyridoxyl-amines are prepared by reacting pyridoxal with a primary amine to form a Schiff base which is then hydrogenated in the presence of a hydrogenation catalyst, e.g. a platinum metal catalyst, to form the required amine which may be of the formula <FORM:0694162/IV (b)/1> wherein R represents an alkyl, aryl, aralkyl or heterocyclic radical.  The hydrochloric acid salts of the above amines may be prepared by the usual method.  The above reaction may be carried out in an anhydrous aliphatic alcohol containing less than 10 carbon atoms, e.g. methyl or ethyl alcohol.  Suitable amines which may be used are tryamine, b -phenylethylamine, pyridoxamine, histamine, tryptamine, benzylamine, isobutylamine and aniline. When aqueous alcohol is used for the reaction between histamine and pyridoxal, a cyclic pyridoxyl histamine of the formula <FORM:0694162/IV (b)/2> is obtained as distinct from N-pyridoxyl histamine of the formula <FORM:0694162/IV (b)/3> which is obtained when using absolute alcohol as the reaction medium.  In the examples the specific amines referred to above are reacted with pyridoxal in an absolute alcohol to form the corresponding Schiff's base which is then reduced with hydrogen to form the N-pyridoxylamine, and histamine is reacted with pyridoxal in aqueous ethyl alcohol to form the cyclic pyridoxyl histamine of the formula given above.

Abstract: 1,085,464. Lubricating spindles. JAMES MACKIE & SONS Ltd. July 9, 1964 [July 26, 19631. No. 29764/63. Heading D1D. In an arrangement where a bobbin sleeve is mounted on a dead spindle extending from a base member shaped as an oil reservoir, the spindle having a longitudinal bore communicating with the reservoir, a non-return valve is provided which operates when the carrier is raised, to prevent the bore from filling with oil, and so giving a false indication of the amount of oil in the reservoir. In the arrangement shown in Fig. 2, which basically corresponds to that of Fig. 1 of Specification 1,085,463, a dished washer 20 is placed in the space 21. In normal operation, the washer lifts slightly to allow oil to return from the bore 11 to the reservoir 5 via passages 14, 22. When the carrier is removed, oil starts to'rise in the bore and the washer immediately falls to block communication between the passages 14, 22; when a fresh carrier is put on the spindle, the rush of air down the bore lifts the washer to block the passages 22 and prevent air getting into the reservoir. In other forms, (a) a tapered plug rests loosely on the bottom of the nut on the end of the bore acting to seal off the bore from the reservoir when the carrier is removed, (b) a valve 27, Fig. 3 with a projection 29 is placed at the top of the spindle between a plug 25 and a cup 28. The plug has an opening 26 into which the projection, normally extends, and the valve has an aperture 30 and the cup an aperture 31. When the carrier is moved upwardly along the spindle, reduced pressure in the bore 11, causes the projection to leave the opening 26 to vent the bore to atmosphere.
