Title: Thiophosphoric acid esters and process for their manufacture
IPC: C07F9/173
Filed: 1958-01-03
Abstract: The invention comprises thiophosphoric acid esters of the formula NC-CH=C(R)-CH2-S-P(X)(OR1)2 in which R is hydrogen or a lower alkyl radical having up to 4 carbon atoms, X is oxygen or sulphur and R1 is a lower alkyl radical having up to 4 carbon atoms.  They may be obtained by reacting the corresponding 1-cyano-allyl halides with salts of appropriate dialkyl thiol- or dialkyl thiono-thiol phosphoric acids.  Specified halides are the chlorides and bromides and specified salts are the alkali metal and ammonium salts.  Instead of using the salts of the dialkyl thiol- or dialkyl thiono-thiol phosphoric acids the free acids may be used, the reaction in this case being carried out in the presence of suitable acid binding agents, e.g. alkali metal carbonates, hydroxides or alcoholates, or organic amines especially tertiary amines.  The reaction is generally carried out at between 0 DEG  and 70 DEG  C. and in the presence of an inert organic solvent, e.g. an alcohol, an aliphatic ketone, e.g. acetone or methyl ethyl ketone, benzene or toluene.  Examples are given for the production of: (1) (C2H5O)2P(O)SCH2.CH=CHCN; (2) (nC3H7O)2P(O)S.CH2.CH=CH-CN; (3) (C2H5O)2P(S)SCH2-CH=CHCN; (4) (C2H5O)2P(O)SCH2.C(CH3)=CH-CN; and (5) (C2H5O)2P(S)S-CH2-C(CH3)=CH-CN the reaction being carried out in each case using the ammonium salt of the appropriate O,O-dialkyl thio- (or dithio-) phosphoric acid and the corresponding 1-cyano-allyl- (or methallyl-) halide. The products are stated to be valuable as insecticides (see Group VI).ALSO:An insecticidal composition comprises a thiophosphoric acid ester of the formula (R1O)2P(X)S-CH2-C(R)=CH-CN in which R is hydrogen or a lower alkyl radical having up to 4 carbon atoms, X is oxygen or sulphur, and R1 is a lower alkyl radical having up to 4 carbon atoms (see Group IV (b)) and a solid or liquid carrier or diluent.  Specified carriers or diluents are talc, chalk, bentonite, clay, water (if necessary with a commercial emulsifier), alcohols, e.g. methanol or ethanol, ketones, e.g. acetone or methyl ethyl ketone, and liquid hydrocarbons.  The composition may also contain a known insecticide and/or a fertilizer.  A specified composition comprises a mixture of a compound of the formula (C2H5O)2P(O)S CH2-CH=CH-CN with acetone, water and benzyl hydroxy diphenyl polyglycol ether as emulsifier.

IPC: C21D9/02
Filed: 1957-01-04
Abstract: 846,283. Making springs; altering physical structure. AMERICAN STEEL FOUNDRIES. Jan. 4, 1957 [July 10, 1956], No. 447/57. Classes 83 (2) and 83 (4). A method of making an extended life coil spring from a bar of spring steel comprising a single heating of the bar to a temperature suitable for coiling and above its upper critical temperature, next coiling the bar and finally subjecting the coiled bar to shot peening is characterized in that, after the coiling and before the shot peening, the bar is quenched before it has cooled to a temperature below its lower critical temperature. The coiling temperature for carbon steel is approximately 1625‹ F. and alloy steels approximately 1575‹ F. During the coiling operation an electronic device automatically rejects any workpiece the temperature of which has fallen below the minimum quench temperature of 1450‹ F. Following the oil quench the springs are tempered within the range of 200‹ to 1000‹ F. and preferably at 800‹ F. and may be preset by setting them solid a plurality of times. Upon completion of the set-down operation or upon cooling from the tempering if the springs are not set-down, the springs are shot peened to extend their fatigue life.

Title: Improvements in Weighing Scales.
Inventor: WHITE ALFRED ERNEST
IPC: G01G1/00
Filed: 1917-01-19
Abstract: 110,257. White, A. E., (Toledo Scale Co.). Jan. 19, 1917 Indicating-mechanism.-Relates to a weighing scale having a pair of pointers for indicating net, gross, and tare weights, and comprises means for locking one pointer in its indicating position whilst permitting of relative adjustment of the other pointer. The indicating spindle 22, Fig. 2, is actuated by any suitable weighing mechanism such as the rolling-segment mechanism 9, 16 shown in Fig. 1; this mechanism being of the type described in Specification 15724/13. Secured to the front end of the spindle is a pointer 27 and a shaft 32. On the shaft 32 is a sliding sleeve 37 carrying a second pointer 36 and urged by a spring 41 into frictional engagement with a disk 35 on the shaft 32. The operator by grasping a knob 40 is thus able to disconnect the pointer 36 from the shaft 22 and adjust the pointer 36 relatively to the pointer 27. Near the zero point of the graduated dial 23 is an electro-magnet 47 arranged in circuit with a magnetic brake 43, batteries 52, and a press button 53. In using the apparatus, the empty box or other container is placed upon the weighing platform, thus causing the two pointers to move over the dial. The operator then presses the push-button 53. thereby energizing the electro-magnet 47 and also causing the magnetic brake 43 to engage frictionally with a disk 42 on the indicating spindle 22 and hold the pointer 27. The operator now adjusts the pointer 36 to the zero position, the attraction of the electro-magnet 47 automatically assisting the exact adjustment. The commodity is placed in the box and the pointers again rotate, the net weight being indicated by the pointer 36, the gross weight by the pointer 27, and the tare by the difference between the two indications. In a. modification, a second series of graduations are arranged inside the series 23, but in the reverse direction, so that the pointer 36 may be set behind the zero by an amount equal to the tare, the pointer being capable of reading in connexion with both series of graduations. The push-button 23 may be arranged on the end of a swivelling arm so as to be brought into any convenient position for the operator.
