Title: Preparing n-thioamines
Inventor: HARMAN MARION WESLEY
IPC: C07D295/26
Filed: 1955-02-15
Abstract: Polymeric N : N1-dithio-amines are prepared from a diamine and a sulphur monohalide in a substantially water-immiscible inert organic solvent, the sulphur halide and an aqueous inorganic alkali being added concurrently to the reaction mixture during at least a part of the process, the molar proportion of the former being always greater than that of the latter.  It is possible to add half the theoretical quantity of sulphur halide first, then sufficient alkali to neutralize the hydrogen halide liberated and then to add the remainder of each concurrently.  Alternatively both may be added concurrently throughout.  The solvent used should be inert to the sulphur halide and should preferably be a non-solvent for the product, e.g. aliphatic, cycloaliphatic and aromatic hydrocarbons, ether, chloroform, carbon tetrachloride, trichlorethylene and chlorobenzene.  The reaction may be carried out at 0-60 DEG  C., with efficient stirring.  Examples show the production of dithio derivatives of piperazine and 2 : 5-dimethyl-piperazine, and it is stated that C-alkyl, C-aryl and C-aralkyl derivatives in general may be used.ALSO:N : N1 - dithio - diamines are prepared from a secondary amine and a sulphur monohalide in a substantially water-immiscible inert organic solvent, the sulphur halide and an aqueous inorganic alkali being added concurrently to the reaction mixture during at least a part of the process, the molar proportion of the former being always greater than that of the latter.

Filed: 1947-02-20
Abstract: 644,127. Engine stop-gear. WHEELCO INSTRUMENTS CO. Feb. 20, 1947, No. 4998. Convention date, Dec. 31, 1942. [Class 122(iv)] [Also in Groups XXII and XL(c)] A control system for a wire drawing apparatus comprising a drum 1, a die 4 and a drum 7 driven by a motor 8, whereby the motor 8 is stopped when a wire 2, which must be of magnetic material, departs from predetermined conditions, comprises a tuned inductance 20 through which the wire 2 passes, which forms part of an oscillating circuit including a valve 35 and a further tuned circuit 40. The output of the valve 35 is direct coupled to an amplifier valve 47, included in the anode circuit of which is a relay 12 which controls a switch 11 which when released switches off the motor 8 and applies a brake 16 to the drum 7. The anodes of the valves 35, 47 are supplied by windings 46, 55 on a transformer 43 and a winding 56 supplies positive bias for the valves 35, 47, and opposes the voltage developed across a resistor 53 to maintain a minimum negative bias on the valve 47 which thus draws sufficient current to operate the relay 12. A tapping on the relay 12 is connected to the grid resistor 52 of the valve 35 and provides an opposing negative bias on the. valve 35. Detuning of the inductance 20 due to breakage or other variation of the wire 2 increases the current drawn by the valve 35, increasing the voltage drop across the resistor 53 thereby biassing the valve 47 negatively and decreasing the anode current which is then insufficient to maintain the relay 12 which trips the motor 8 and operates a visual signal 65. The voltage drop across the relay 12 decreases and hence the opposing negative bias on the valve 35, provided by the centre tap, which tends to still further increase the current drawn by the valve 35.

A gymnastic frame hinged to a wall or the like, so as to swing between an "open" position, e.g. perpendicular to the wall, and a closed position against the wall, is capable of limited vertical movement and has a mechanism for effecting upward movement of the frame by lever action between the frame and the floor of the building and effecting or permitting downward movement of the frame. As shown a gymnastic frame 11 is secured to the wall by hinges 17, 18 which permit limited vertical movement. Studs 19, 20 are carried at the opposite edge 16 of the frame 11 and engage slots 26 in supports 24, 25 secured to the wall when the frame is in its " closed position." The lower end of edge 16 carries a pivoted lever 21 with a wheel 23 which rests on the floor when the long arm of the lever is vertical. When the lever is moved to the position shown in chain dotted lines, Fig. 2, wheel 23 engages the floor and raises the frame to disengage pins 19, 20 from slots 26 and allow the frame to swing freely to its "open" position. The frame may be held in its open position by the top stud 20 engaging a slot in a cross beam or the like. Alternatively the linkage described in Specification 721,487, [Group XXI], may be employed.

Abstract: 894,263. Ejection seats for aircraft. MARTIN J., and MARTIN-BAKER AIRCRAFT CO. Ltd. Feb. 1, 1961 [Feb. 12, 1960], No. 5125/60. Addition to 761,457, Class 4. [Also in Group XXV] In an aircraft ejection seat in which the frame 1 of the latter carries a transversely slidable spring-pressed locking plunger 15 for engagement through a hole 25 in a part 26 of or on the gun cylinder and with a retaining collar 9 on part of said gun movable axially relatively to said cylinder, such locking plunger 25 being adapted to be displaced axially, to free the seat from the gun, by the initial axial movement of the said collar-provided part 26 of the gun relatively to the seat frame 1 on the firing of the gun, a further or inner independent axially slidable plunger 35 is located in a longitudinal bore 33, 34 through the said locking plunger, this inner plunger 35 being spring urged in a direction towards the nose of the locking plunger 15 so that the nose of the inner plunger 35 tends to project beyond the tip of the nose of the locking plunger 15, and the inner and locking plungers are so constructed and dimensioned that the relative positions of readily visible parts thereof clearly indicate whether the looking plunger is or is not properly engaged through the said hole in the co-operating part of the gun cylinder and in full engagement with the said retaining collar 9 of the said movable part of the gun. The seat frame 1 comprises two side beams 2, 3 united by a top block 4 having a central aperture 5 through which the upper end of the breech unit 6 projects, the breech unit being prevented from rotation in block 4 by a radial pin 7 engaging in a keyway 8 in the breech unit. A collar 9, attached to the breech unit, is formed with a frusto-conical peripheral groove 13 engaged by the correspondingly shaped nose of plunger 15 which is housed within a bore 16 in block 4 and urged into engagement with groove 13 by a spring 24 retained by a cap 21. The bore 33 in plunger 15 is larger in diameter than bore 34 to accommodate a spring 37 which urges a head 36 on plunger 35 into contact with groove 13. Plungers 15 and 35 are of the same overall length and their flush outer ends are in alignment with the outer face of spring-retaining collar 21 so that it may be readily observed if the seat is not correctly locked to the gun cylinder. In operation, firing of the ejection cartridge initially drives the top face of collar 9 against a shoulder 10 in block 4, this free movement causing the plungers 15, 35 to be cammed out of groove 13, thereby freeing the seat frame for subsequent ejection. To enable the plungers to be withdrawn manually for servicing of the seat, the outer end of plunger 15 is threaded whereby it may be extracted by a knurled nut 28. If desired the outer ends of the plungers may be anodised or painted in contrasting colours.
