Title: Process for the production of pyridoxal oxazolidines and a pyridoxal-5-ortho-phosphoric acid ester
IPC: C07F9/58
Filed: 1960-03-29
Abstract: The invention comprises pyridoxal oxazolidines having the formula <FORM:0880595/IV (b)/1> in which R1, R2 and R3 are selected from hydrogen, alkyl, aryl, substituted aryl or cycloalkyl radicals. These may be prepared by reacting pyridoxal or pyridoxal-hydroxy-sulphonic acid with a b -amino alcohol in aqueous solution at a pH of 9-9.5. in Examples 1, 3 and 4 the b -amino alcohol is ephedrine and the product is 2-(31-hydroxy - 51 - hydroxymethyl - 21 - methyl - pyridyl - 41) - 3,4 - dimethyl - 5 - phenyl - L p  - oxazolidine.  In Example 5 b -benzylamino ethyl alcohol is used to produce the corresponding -N-benzyl-oxazolidine and in Example 6 b -cyclohexylamino ethyl alcohol produces the -N cyclohexyl oxazolidine, and in Example 7 b -hydroxy ethyl aniline produced the corresponding -N-phenyl oxazolidine.  The pyridoxal oxazolidine may then be phosphorylated, e.g. with a mixture of ortho phosphoric acid and phosphorus pentoxide, to produce the corresponding pyridoxal oxazolidine 51-ortho- and poly-phosphoric acid esters and the reaction products subjected to hydrolysis to produce a pyridoxal-51-ortho-phosphoric acid ester.

Title: Improvements in or relating to the manufacture of pneumatic tyres
IPC: B60C11/12
Filed: 1937-04-21
Abstract: In the manufacture of pneumatic tyres having the tread formed with fine cuts which impart to the tyre anti-skidding properties, the cuts are formed in the tread prior to vulcanization and a medium which will prevent the walls of the cuts from sticking together during the vulcanization is introduced into the cuts either during the formation thereof or subsequently thereto.  The cuts may be formed in the tread after the tyre is shaped or prior to shaping, e.g. when the tyre is manufactured by a process in which a rubber band to form the tread is first produced and is afterwards applied to a carcase to form the complete tyre the cuts may be formed in the rubber band during the extrusion thereof, and when the band consists of two separately formed layers doubled together the cuts may be formed in the outer layer only and throughout the thickness thereof prior to uniting with the other layer.  The medium which prevents the walls of the cuts from sticking together may be liquid, pasty or dusty materials similar to those which are used to prevent the adhesion of the rubber to the moulds during vulcanization, e.g. water or alcohol having dispersed, emulsified or dissolved therein talc, mica, china clay, phenol, soap, glycerine, gelatine, glue, sugar, gum arabic, dextrine, sodium silicate, or sodium hyposulphite.  The cuts may extend in any direction in the tread, e.g. they may lie in planes parallel with or perpendicular to or inclined to the geometrical axis of the tyre or in irregular directions; they may be straight, zigzag or curved; they may extend only a portion of the width of the tread; and the depth and relative distance of the cuts may vary.

Filed: 1929-04-15
Abstract: 312,682. Matthews Corporation, W., (Assignees of Birkenmaier, T.). May 31, 1928, [Convention date]. Ground anchors.-A hole 11, Fig. 2, is formed in the helical flange 5 on the body portion 1, Fig. 5, of the anchor, and the lower end of the wrench tube 17, which is slipped over the anchor rod 9 screwed into a tapped recess 7 at the head of the anchor body portion, is formed with a recess 21, Fig. 3. The sides of the recess are formed with retaining lugs 27 and, when the wrench tube is slipped over the anchor rod the sloping top 23 of the recess rests on the portion 25, Fig. 2, of the helical flange between the end of the flange and the hole therein. The anchor is driven into the ground by the clockwise rotation of the wrench tube, the leading edge 33, Fig. 3, of the recess therein contacting with the end of the helical flange on the anchor body, and the anchor is retrieved by the anti-clockwise rotation of the wrench tube when the trailing edge 31 of the recess 21 contacts with the end a, Fig. 2, of the hole 11 in the helical flange. An enlarged recess 28, Fig. 5, is formed at the top of the tapped recess 7 in the anchor body, thereby forming a rim against which an unthreaded portion of the anchor rod rubs on the bending of the anchor rod due to side load, thereby preventing breaking of the rod at the upper end of the threaded portion of the rod where the rod is weakened by the thread which at this point is imperfectly formed by the die and therefore prevents the anchor rod from being screwed fully home into the recess 7.

Title: Improvements in or relating to automatic traffic control systems
IPC: G08G1/065
Filed: 1934-04-20
Abstract: 436,883. Railway signalling systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and RENSHAW, A. P. B., Brookwood, Dickerage Road, Kingston Hill, Surrey. April 20, 1934, No. 11969. [Class 105] [See also Group XXXVIII] A signal is given if the flow of traffic into a controlled section of railway greatly exceeds the flow out of the section. The signal may prevent further flow into the section. As shown in the drawing, cam contacts C2 and C4 are normally closed and each vehicle passing over the " IN " detector, which may be of the type disclosed in Specification 360,924, [Group XXXVIII], operates relay E so that contact e1 allows a charge to pass to condenser QA. The connection from e1 to resistance XA is such that a predetermined number of pulses, for example 40, is required to charge QA to the striking voltage of lamp FA. Each vehicle passing the " OUT " detector operates relay L and allows part of the charge on QA to escape. If the inflow exceeds the outflow to a large extent QA becomes fully charged, lamp FA strikes and relay A operates so that magnet S turns the cam-shaft to open contacts C2 and C4 and close contacts C1, C3 and C5. Contact C5 closes the signal circuit, which may be such as to prevent flow into the section, and contact C3 enables the charging of QA to be controlled by relay L. When the flow moves out of the section, the condenser QA again charges and magnet S steps the shaft to restore the apparatus to its original condition. To ensure return of the apparatus to normal after a current failure, or the like, a slow-to-operate relay may be provided in the mains circuit. This relay would be normally energized and would open contacts in a circuit of the magnet S including cam contacts closed when the cam-shaft is in the blocking position. If current failed with the shaft in this position, when the current is restored the magnet S would be operated, during the slow operating period of the relay, to restore the shaft to normal. The contacts of the relays E and L may be arranged to be closed for a predetermined time no matter how long the detector circuits are closed.
