Title: Process for preparing 1,2-diamino cyclohexane and its derivatives
Filed: 1961-12-28
Abstract: Cyclohexane-1,2-diamine sulphate is prepared by reacting the sulphuric acid semi ester of 2-aminocyclohexanol with ammonia in water, methanol or ethanol in the liquid phase at 100 DEG  to 180 DEG C., preferably 120 DEG  to 140 DEG  C., preferably at 20 to 30 ats. The product may be recovered by distilling off ammonia, which can be absorbed in another portion of solvent for re-use, then crystallizing.  The free base may be liberated by the reaction with alkalis, or salts of other acids may be prepared by the reaction with other acids.  Either the free base or the salt thus obtained may be converted to the tetra-acetate derivative by reacting with chloracetic acid under alkaline conditions. The examples describe the preparation of cyclohexanone-1,2- diamine sulphate and the tetracetic acid derivatives.

Filed: 1966-11-21
Abstract: 1,166,467. Single lens reflex cameras. EASTMAN KODAK CO. Nov. 21, 1966 [Nov. 19, 1965], No. 52113/66. Heading G2A. A single lens reflex camera comprises a focal plane shutter, a pivotally mounted mirror returning to the viewing position immediately after exposure, a locking member for preventing a second advance of the actuating member for shutter cocking and/or film transport, after a complete advance thereof and before the mirror return, and a locking device preventing the return of the actuating member to its initial position after an incomplete advance, it being possible to neutralize said locking device by the camera release irrespective of the actuating member's position. As shown in the Fig., the mirror 1 has returned to the viewing position. Advance of the shutter cocking actuating member 18 turns a pinion 52 mounted therewith to drive a rack 51 in the direction E, a lug 51a on the rack acting on a lever 50 to pivot it about a shaft 48. The end 50b of the lever 50 moves a slide member 30 against a spring-bias 40 until the end 50b is engaged by a lever 56. A pawl lever 59 is biased to engage ratchet teeth 51b of the rack 51 to prevent the return of the actuating member 18, until, at the end of the advance, a lug 51c on the rack 51 disengages the pawl lever 59 to move it behind the camera release 54 where it is held inactive, the rack 51 and actuating member 18 return to their initial positions, and a pawl 62 on the rack 51 engages the pinion 52. Depression of the release 54 raises the mirror 1, closer the diaphragm setting ring 25, and actuates the shutter and, at the end of its stroke, releases pawl lever 59 to re-engage the rack 51 after the lever 56 has released the lever 50 which pivots under the action of spring 40 to re-engage the lug 51a and disengage the pawl 62 from pinion 52. If an incomplete advance of member 18 is made, depression of the release 54, causes an angled lever 58 to pivot and act on a lug 59b of the pawl lever 59 to disengage it from the ratchet teeth 51b, allowing the rack 51 and member 18 to return to their initial positions. Repetition of this process enables a film to be fed through the camera without actuating the shutter.

Abstract: 1,254,128. Tensile testing apparatus. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. Oct. 24, 1969 [Oct. 24, 1968], No. 52292/69. Heading G1S. A tensile test specimen held between a movable cross-bar 27, Fig. 2 and a relatively fixed stirrup 57 may be tensioned by rotating a coupling disc 10 by an electric motor 2 and flywheel 3 driving a mating coupling disc 9, Fig. 1. The coupling 10 rotates a cam 7 mounted in bearings 12, 13 and having a protuberance 14, Fig. 5c, the cam normally bearing on a roller 15, Fig. 5b, in the centre of a stirrup 16 pressed by a spring against the cam and sliding on four fixed guide rods such as 17 and 18. The sliding movement of the stirrup 16 by the cam is transferred by fixed tie rods 28, 29 to a cross-bar 27 slidable on fixed guide rods 42, 43 screw threaded through a stirrup 57 which may be driven along the screw threads by means of a motor 58 and a chain drive 60. The specimen to be tensile tested is a rod 71, Fig. 9, which is threaded into sleeves 74, 75 abutting against a fixed shoulder 77 of the stirrup 57 and against a shoulder on the bar 27 which is moved away from the stirrup 57 by translation of the stirrup 16 and rods 28, 29. The cam carries a lug 99, Figs. 5c, 5d, which when the cam rotates abuts against a stem 98 on an arm 88 so that the arm is drawn downwardly and pivots down a roller 83 carrying the cylinder 15. The stem 98 is moved into the path of the lug 99 by operation of a solenoid and the cylinder 15 is contacted and pushed back by the protuberance 14 on the cam 7. When the protuberance 14 has passed the roller 83 and cylinder 15 they are freed and returned with the arm 88 by a spring 91 and the stem 98 is retracted to avoid a further test extension movement. The specimen may be rapidly heated or gas or water cooled by apparatus placed between the rods 42, 43 and the speed of the cam 7 may also be varied to alter the time of deformation. The position of the test specimen may be altered with respect to the cross-bar 27, Fig. 10 (not shown) by rotating a toothed bush (108) screw threaded to one end of the specimen.

Apparatus for administering anaesthetics comprises an inlet 53 for anaesthetic carrier gas, an outlet 54 connectible to a breathing mask, a vapourisirig chamber 1 for liquid anaesthetic, and a valve 3 for controlling both the path of flow of the carrier gas through the apparatus and the charging of liquid anaesthetic into the vapourising chamber, a control member 57 of the valve being adjustable to any one of three positions, these being a first position in which the carrier gas is directed to flow from inlet to outlet without passing through the vapourising chamber and the or each charging passage to such chamber is closed, a second position in which the carrier gas is directed to flow from inlet to outlet without passing through the vapourising chamber and the or each charging passage to such chamber is open, and a third position in which the carrier gas is directed to flow from inlet to outlet via the vapourising chamber and the or each charging passage is closed. The control valve 3 preferably comprises a rotary cock 57 provided with passages for connecting inlet, outlet, and vapourising chamber. The latter houses a proportioning valve assembly 6, temperature-responsive valve assembly 7, and wicks 8, 9 Which define a space 10.

In operation, carrier gas entering inlet 12 passes through space 28 into space 10 via openings 29, 30 and over wick 8. The carrier gas then entrains anaesthetic vapour by passing through wick 8, from whence it passes to space 34 via openings 40 and 35. The temperature-responsive valve assembly 7 comprises a valve member 44 slidably mounted on shaft 21 and biassed downwardly by spring 45 and secured to a fixedly mounted temperature-sensitive capsule 48 immersed in the liquid anaesthetic in the vapourising chamber.
