Title: Sulfatriazines and method of preparation
IPC: C07D251/22
Filed: 1960-03-14
Abstract: The invention comprises sulpha-triazines of the formula <FORM:0905544/IV (b)/1> wherein R1 and R2 are ethyl, n-propyl or isopropyl groups and R is a hydrogen atom or an alkyl or alkanoyl group of 1-6 carbon atoms and, in the case where R is an alkyl or alkanoyl group, the sulphanilyl-imino-dihydrotriazine isomers of I wherein the R substituent is on the 1- or 3-position of the triazine ring. It comprises also the preparation of these compounds by reacting 2-halo-, 2-thioether or 2-etherified hydroxy-derivative of the appropriate 4,6-dialkyl triazine with the anion of a p-substituted sulphonamide A.C6H4.SO2NH2, wherein A is an amino group or a group convertible to amino by reduction or hydrolysis, where necessary, converting A into an amino group and, if desired, converting the resulting product wherein R is hydrogen into the corresponding alkali-metal, alkyl or alkanoyl derivative.  Specified products include the 2-sulphanilamido- 4,6-diethyl- and 4,6-di-n-propyl-, triazines, N1-methyl-sulpha-4,6-diethyl-triazine and 2 - sulphanilimido - 1 - methyl-4,6-diethyl-1,2-dihydro-triazine. Triazine derivatives used as starting materials bearing an alkoxy, aryloxy, alkylthio or arylthio group in the 2-position and substituents R1 and R2 in the 4- and 6- positions are made by reacting an O-alkyl or O-aryl isourea or S-alkyl or S-aryl isothiourea salt with an imidate R111C(:NH).O-alkyl, wherein R111 is an ethyl, n-propyl or isopropyl group. 2,4-Diethyl-6-chloro-s-triazine is made by reducing 2,4-bis(a ,a -dichloroethyl)-6-hydroxy-s-triazine with zinc dust and ammonia and treating the resulting 6 - hydroxy compound with phosphorus pentachloride.  Specification 905,545 is referred to.

Abstract: 899,802. Two-part couplings. UNITED CARR FASTENER CORPORATION. March 15, 1960 [April 30, 1959], No. 9170/60. Class 38 (1). The body parts 10, 11 of a two-part connector are hingeable together at one end and are retained in the engaged position by latch members 36, 37. Adjacent contacts 12 of the male body part 10 are electrically isolated one from the other by spacers 16 and have integral ears 17 which move within slots in the spacers and guide the contacts. The contacts 14 of the body part 11 are similarly guided and isolated. All the contacts are resilient and tend to disengage the body parts. A hinge device comprises a metal fulcrum member 23 mounted on the body part 11 and intended to be inserted in an opening 22 formed in a member 21 secured on the body part 20. The head 45 of the latch member 37 is provided with helical channels 43, 44 to receive a pair of ears 41, 42 formed on a metal collar 36 secured in the body part 10. A spring 49 normally urges the head 45, shank 46 and knob 47 of the latch member away from the body part 11. In using the connector, the body parts are hinged together and, after moving the parts into mating juxtaposition, the latch member 37 is displaced towards the collar 36 and rotated. The collar ears 41, 42 engage in the helical channels 43, 44 and the body parts are drawn together. The ears 41, 42 finally engage in flattened end portions of the channels and the member 37 is prevented from turning. The body parts are thus locked in mating relation. Specification 865,228 is referred to.

Patent GB-342203-A (GB)
Title: Lathe tail stock
IPC: B23B23/00
Filed: 1930-03-24
Abstract: 342,203. Turning. BRILL, K. F., 68, Nordoberhausenstrasse, Sterkrade, Rhineland, Germany. March 24, 1930, No. 9334. Convention date, March 27, 1929. [Class 83 (iii).] In a lathe tailstock wherein the back centre is maintained in contact with the work by fluid pressure, relief means are provided to permit the centre to recede when the work expands due to a rise in temperature. The centre 4, Fig. 1, is attached to a plunger 1 sliding in a cylinder 7 formed in the tail-stock 3. An extension 8 of the plunger slides through a stuffing box 9 which divides the tail-stock into two compartments, and is secured by a wedge 10 to a block 2 which may be advanced or retracted within the tail-stock by the usual screw and hand wheel 6. In operation, the centre is pressed against the work by the wheel 6, pressure is admitted to the cylinder 7 from a hand pump or a pressure line and the block 2 is then withdrawn slightly within the limits of the clearance 14 provided between the slot 27 in the extension 8 and the wedge 10. As the work expands the centre is pushed back and fluid is displaced through a relief valve to the fluid reservoir, the clearance 14 being less than the penetration of the centre into the work so that rearward movement of the centre is stopped before the work becomes disengaged. As the work contracts again, fluid returns to the cylinder 7 from the main or is supplied by the pump. Should the fluid pressure fail due to fracture of a pipe &c. the centre cannot recede a distance greater than the clearance 14. A gauge 26 is provided for controlling the fluid pressure. In a modification the centre 4, Fig. 3, is slidable in a cylinder 16 which is movable within the tailstock 3 by a screwed stem 17 therein and a nut 18 carrying a hand wheel 19. Rotation of the hand wheel feeds the centre against the work, whereupon rotation of a wheel 25 screws a spindle 21 into the cylinder and causes the pressure to be increased by means of a plunger 20, a spring 22 being interposed between the plunger and spindle. Expansion of the work forces back the plunger 20, and if the gauge 23 registers too high a pressure this may be relieved by the wheel 25. The spring 22 returns the centre as the work contracts and the tail-stock is slotted at 24 to allow the gauge 23 to move with the cylinder 16.

Spraying nozzles 30 are spaced along a pipe 10 divided by a web 12 into manifolds 14, 16, and each nozzle has a valve chamber 36, Fig. 2, with a ball valve member 52, ports 38 and 54, and a main liquid outlet 40 adjacent an auxiliary outlet 44. The outlets are located in a plate 33 held in position together with a spray deflector 42 by a screw plug 35. For normal spraying liquid is fed to the manifold 16, Fig. 4, and to each port 38 of the nozzles via a line 22 and valve 24, and flow from manifold 14 is prevented by a valve 20 in line 18. The ball 52 is urged on a valve seat around the outlet 44 and liquid is sprayed from the main outlet 40 only. When it is required to purge or flush the nozzles to remove deposits &c., the various valves are arranged as in Fig. 5 with a valve 28 in a line 26 partially opened, whereby liquid flows into each nozzle through the port 54 and from the nozzle via the main outlet, and also the port 38 to waste. Valve 28 is then fully opened whereupon the ball 52 falls to a seating around the port 38 and liquid flows through both the main and auxiliary outlets. In a modified liquid supply and flushing arrangement an opening is provided in the web between the manifolds, spray liquid is fed to the upper manifold and normally flows to the nozzles through the ports 54, and an outlet pipe with a normally closed valve is connected to the lower manifold.

The subtraction circuit subtracts either the combed chrominance component or the bandpassed chrominance component from the television signal to produce a separated luminance component as a function of the phase of signals obtained from the delay network. Illustratively, the subtracter subtracts the bandpassed chrominance component from the television signal in the presence of color transitions in the vertical direction, and in the presence of 180 DEG  color transitions.
