Title: Improvements in the manufacture and production of methanol
IPC: C07C29/151
Filed: 1927-09-19
Abstract: 308,181. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 19, 1927. Methanol is prepared by the catalytic hydrogenation of oxides of carbon at ordinary or shghtly-raised pressure and at low temperature, preferably 100-250‹ C, by the use of catalysts, comprising copper and one of more oxides of a metal of groups 2 to 7, obtained by precipitating aqueous solutions of the metal salts with alkalies at moderate temperatures, e.g. below 30‹ C., and reducing the washed precipitate with hydrogen, carbon monoxide or mixtures thereof diluted with inert gases. The metals specified for admixture with the copper comprise beryllium, aluminium, zinc, yttrium, magnesium, lanthanum, uranium, lead, manganese, antimony, cerium and thorium; elements of group 8 should not be present. The copper is maintained in the hydroxide form prior to reduction and the latter is conducted with care at a temperature of 50‹ C rising to 250‹ C., the reducing gas being mixed with such inert gases as nitrogen, methane or water vapour. The reaction gases, which may be in varying proportions and admixed with inert gases, are freed from catalyst poisons. An example is given of the preparation of methanol by passing a mixture of carbon monoxide at atmospheric pressure and a temperature of 150‹ C. over a catalyst prepared by precipitating a solution of copper nitrate (2 mols.) and magnesium nitrate (1 mol.) with sodium hydroxide and reducing with a mixture of nitrogen and hydrogen at a temperature of 100-250‹ C.

Title: Improvements in and relating to light projectors
IPC: F21V19/02
Filed: 1936-09-10
Abstract: 467,307. Adjusting electric lamps in light projectors. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 10, 1936, No. 24715. Convention date, Sept. 11, 1935. [Class 75 (iv)] For moving a pivotally mounted electric lamp to either one of two predetermined positions with respect to the reflector of a light projector, the lamp support is moved by means responsive to successive energizations of the lamp. In the form shown, the lamp 10 is carried by a socket 26 mounted on a cross-bar 25 connecting together a pair of arms 19, 20 which are pivoted at 21, 22 to a pair of parallel prongs 17, 18 attached to and projecting vertically above one end of a base 16 mounted in the projector housing 15. For limiting the movement of the arms 19, 20, the latter carry U-shaped members 23, 24 which engage the sides of the prongs 17, 18. A tongue 32 on the cross-bar 25 is engaged by one or other of two surfaces 30, 31 on a cam 29 mounted on a U- shaped rocking member 33 pivoted at 34 to the prongs 17, 18. The cam has a smooth slot 35 and hooked ends 36, 36<1> to accommodate an operating pin 37 on the free end of a link 38 of a toggle mechanism including links 38, 39, 40. The link 40 is pivotally connected to a rigid support 41 and to the core 43 of an operating coil 44. Links 38, 39 are connected together by a pin 47 which slides in a slot 48 in a guide member 49, and springs 50, connected between the rocking member 33 and the lower end of link 38, hold the cam 29 on either side of the pivot pins 34. When the coil 44 is energized the links are lowered, the pin 37 tilts the cam 29, and the springs 50 snap the cam 29 and the lampholder into the new position. When the coil is de-energized the springs 50 raise the links and the pin 37 slides to the upper end of the slot 35. Further energization of the coil causes a reverse movement of the lamp. To reduce current consumption, the circuit to the coil 44 may be opened during operation of the projector by means of a pivoted lever 52 and an auxiliary coil 51 which is energized simultaneously with the lamp 10. When the core 43 descends it engages the lever 52 and moves an armature 54 into engagement with the core 56 of the coil 51. An operating rod 58 on the lever 52 opens a switch in the circuit of the coil 44 and allows the arm 43 and the toggle mechanism to be raised by the springs 50. For manual operation, the pin 47 of the toggle mechanism may be pulled down, against the action of a spring 68, by means of a hook 65 which projects through a bushing 66 in the casing 15 and is provided with an operating handle 67.

Title: Improvements in and relating to light automatic weapons such as carbines
IPC: F41A9/65
Filed: 1952-10-02
Abstract: 710,927. Smallarms. SCHWEIZERISCHE INDUSTRIE-GES. Oct. 2, 1952 [May. 5, 1952], No. 24737/52. Class 119. A light automatic firearm has a reciprocating barrel 3 and a fixed breech-block 4, means for locking the barrel in the rear position until the projectile has left the firearm, and a muzzle brake 7 on an actuator 8 which latter is movable relative to the barrel and co-operates with it. In the construction shown, the locking means consists of a lever 14 pivoted on the barrel and engaging a shoulder 15 on the fixed casing 1, the lever being held downwards by a part 21 of the actuator. A slight pull on the trigger 32 for single shot firing, or an extended pull for continuous firing, withdraws a sear 37 to release the firing pin 6 in the breech-block 4. When the bullet from the leading round 26<SP>1</SP> leaves the firearm, the gases acting on the muzzle brake pull the latter forwards against the action of a spring 10, and when a shoulder 22 of the actuator engages a shoulder 23 on the barrel, the barrel also moves forwards. During these movements the part 21 of the actuator has moved clear of the locking lever 14 and has depressed the front arm 40 of a lever 17 whose rear arm 41 is thereby lifted to engage and free the locking lever. The forward motion of the actuator is limited by a shoulder 43 on the casing 1, and that of the barrel by the engagement of the lever 14 with the rear face of the actuator. When the parts return under the action of the spring 10 a fresh round 26, which has been moved upwards by the magazine spring 27, is in a position to engage in the chamber 31. During the return stroke a groove 39 in the actuator permits the lever 17 to return to its initial position, and a wedge face 20 on the actuator depresses the lever to the locking position.

Title: Electric regulator with self-magnetized transductor
IPC: H02P9/32
Filed: 1947-09-12
Abstract: 638,099. Automatic voltage control systems ; rectifying. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Sept. 12, 1947, No. 25053. Convention date, Sept. 21, 1946. [Classes 38 (ii) and 38 (iv)] A self-magnetized transductor is further magnetized in proportion to the output by an additional component of current in one of the control windings so as to increase the selfmagnetizing effect. The output voltage of a rectifier 2, Fig. 1, is controlled by a selfmagnetized transductor 3 in series with the A.C. input and having control windings 5, 6 energized in opposition from the D.C. output through a linear resistor 7 and a voltage variable resistor 8 respectively, The voltage across the control winding 5 is greater than that across the winding 6 by an amount determined by a load current through a resistor 9 in series with the output, the resultant magnetization being additive to the selfmagnetization. In a further embodiment, Fig. 2, the output voltage of an alternator 11 is controlled by a voltage across resistor 14 which opposes the voltage across the selfexcited field winding 13 of the exciter 12. The voltage across resistor 14 is derived from a rectifier 15 supplied from the alternator output via a self-magnetized transductor 16 having control windings 18, 17 energized in opposition from the alternator output through a linear resistor 21 and rectifier 22, and a voltage variable resistor 19 and rectifier 20 respectively. The circuit of control winding 18 includes a further resistor 23 in series with the input to the transductor so that the voltage across the control winding is reduced by a component proportional to the transductor load current, thereby reducing the magnetic effect of winding 18 and since this winding opposes the self-magnetization, the self-magnetization is effectively increased. The invention may also be applied to transductor regulators having one control winding instead of two. Specifications 446,790, 554,525, and 588,822 are referred to.
