Patent GB-553178-A (GB)
Title: Compass compensating means
IPC: G01C17/38
Filed: 1941-11-07
Abstract: 553,178. Magnetic compasses ; gyroscopic apparatus. BENDIX AVIATION CORPORATION. Nov. 7, 1941, No. 14397. Convention date, Nov. 29, 1940. [Classes 97 (ii) and 97 (iii)] Errors in a magnetic compass caused by the vertical component of the earth's magnetic field during turning of the craft on which the compass is mounted are compensated for by the production of an opposing magnetic field controlled in intensity in accordance with the angular movement of the craft. As shown in Fig. 1, two compensating coils 10, 11 surrounding the magnetic compass 12 are supplied with current from a battery 15. The strength of the current required to neutralize the effect of the vertical component at the latitude of the craft is obtained jointly by manual setting of a potentiometer resistor 16, 22 on an angle-of-dip scale 21 and by the automatic adjustment of a further resistor 23, 25 under the action of a rate-of-turn gyroscope 27 in which the precession angle is substantially equal to the correct angle of bank. In a modification, Fig. 2 (not shown), the angular movements of the rate-of-turn gyroscope are transmitted to the armature of a self-synchronous motor supplied from an A.C. source. The corresponding current induced in the displaced armature is fed to a second self-synchronous motor the rotor of which is set manually to the magnetic angle of dip in the locality, by the aid of a graduated scale. The current induced in the rotor according to this angular setting is led, after rectification, to one or other of two sets of compensating coils surrounding the compass, one set of coils corresponding to positions north of the equator and the other south thereof. The selection of the correct set of compensating coils is determined by a commutator simultaneously adjusted when setting the angle of dip. In a further modification, Fig. 3, the compensating field is dependent on an angle of bank indicator comprising a gyro rotor 101 constrained by a pendulum weight 106 which, at the proper angle of bank neutralizes the precessing movement during turns. Movement of a resistor 109 (similar in function to the resistor 23, Fig. 1) relative to a contact 110 causes current to flow to the compensating coils in proportion to the angle of bank and as modified by the angle of dip. The compensating field may similarly be produced under the control of a gyro vertical, Fig. 4 (not shown), or in a further modification, the compensating coils may be replaced by permanent magnets geared together to turn in opposite directions about vertical shafts.

Title: Production of uracils
Inventor: LACEY RICHARD NORMAN
Filed: 1952-06-10
Abstract: 4-Methyluracils are obtained by reacting diketene with an isothiourea R1S.C.(NHR2) : NR3 to produce an oxazinone <FORM:0738581/IV (b)/1> subjecting the oxazinone to the action of aqueous mineral acid to form an oxazindione <FORM:0738581/IV (b)/2> and/or a 4-methyluracil <FORM:0738581/IV (b)/3> and if the oxazindione is formed in substantial amount, reacting it with an amino compound RNH2 to give the 4-methyl-uracil <FORM:0738581/IV (b)/4> R being hydrogen, alkyl or aralkyl, R1 alkyl or aralkyl, and R2 and R3 being alkyl, aralkyl or aryl groups.  In the examples: (1) N,N1-diethyl-S-methylisothiourea is refluxed in benzene with diketene to produce 3-ethyl-2-ethylimino - 2,3 - dihydro - 6 - methyl - 1,3(4) - oxazin-4-one which is hydrolysed by refluxing with aqueous hydrochloric or sulphuric acid to give 3 - ethyl - 2,3 - dihydro - 6 - methyl - 1,3(4) - oxazin-2,4-dione. This is treated with aqueous ammonia giving 1-ethyl-4-methyluracil, or with ethylamine giving 1,3-diethyl-4-methyluracil; (2) 2,3 - dihydro - 6 - methyl - 3 - phenyl - 2 - phenylimino - 1,3(4) - oxazin - 4 - one is prepared from diketene and S-methyl-, S-ethyl-, or S - benzyl - N,N1 - diphenylisothiourea, and is hydrolysed to 2,3-dihydro-6-methyl-3-phenyl - 1,3(4)-oxazin-2,4-dione.  This is warmed with methylamine to give 3,4-dimethyl-1-phenyluracil; (3) 2,3-dihydro-3,6-dimethyl-2-phenylimino-1,3(4)-oxazin-4-one is obtained using N,S-dimethyl-N1-phenyl-isothiourea and is hydrolysed to form a mixture of 1,4-dimethyl-3-phenyluracil and a larger amount of 2,3-dihydro3,6 - dimethyl - 1,3(4) - oxazin - 2,4 - dione. Aqueous ammonia on the latter yields 1,4-dimethyluracil; methylamine yields 1,3,4-trimethyluracil; and benzylamine yields 3-benzyl-1,4-dimethyluracil; (4) 3-benzyl-2,3-dihydro-6-methyl - 2 - phenylimino - 1,3(4) - oxazin - 4 - one, prepared from diketene and N-benzyl-N1-phenyl-S-methylisothiourea, is hydrolysed to a mixture of 1-benzyl-4-methyl-3-phenyluracil and 3 - benzyl - 2,3 - dihydro - 6 - methyl - 1,3(4)-oxazine-2,4-dione.  Aqueous ammonia on the latter yields 1 - benzyl - 4 - methyluracil; methylamine yields 1 - benzyl - 3,4 - dimethyluracil.

Abstract: 280,122. Andrews, L. July 30, 1926. Actuating-mechanism.-The operation of a valve for discharging powdered material from a tank is controlled automatically by means depending on the accumulation of solid material in the lower part of the tank. In the form shown in Figs. 1 and 3, a tank a is surmounted by a chamber 1 in which is mounted a slowly rotating bevel gear 4, Fig. 3, carrying cams 2, 3. A floating spindle 6, the lower end of which is guided in a slot in the upper end of the shaft 13 which carries blades 15 in the tank a, carries rollers 9 adapted to ride on the cams 2, 3. When there is little resistance to the rotation of the blades 15, the cams 2, 3, rollers 9, spindle 6 and blades 15 rotate slowly as a whole; but when coarse particles have collected in the vessel a, the consequent resistance causes the rollers 9 to move up the cams 2, 3, thereby raising a lever z and opening the valve e through an adjustable link y. In a modified arrangement, Fig. 4, the cams 2, 3 are carried by a worm wheel 16, and the rollers 9 are carried by a. horizontal shaft 18 fixed to a Boating spindle 19 in a hole, 20 in the shaft 13, vertical guide bars 23 and guide wheels 24 being provided. The central part of the shaft 18 engages through a ball 26 with an abutment 25 on the valve-operating lever z. Specification 280,123 is referred to.
