IPC: C07C17/18
Filed: 1957-01-14
Abstract: The invention comprises a method for making tetrahalomethanes of general formula XYCZ2 where X, Y and Z are fluorine, bromine or chlorine by reacting a carbonyl halide of general formula <FORM:0848561/IV(b)/1> , with a metalloid pentahalide of general formula MQmZ5-m or the components MQ3 and Z2 thereof, where Q is a halogen of less atomic weight than Z, m is O or 3, and M is a Group V metalloid having +3 and +5 valences, such as, for example, phosphorous, arsenic, antimony and bismuth.  The nature and proportion of the products depends on the initial reactants and on the reaction conditions.  The reactions are usually conducted by placing the reactants in an autoclave and heating to a temperature between about 50 DEG  C. and about 500 DEG  C. Suitable pressures are between about 1 and about 100 atmospheres. The ratio of metalloid halide to carbonyl halide may be between about 0,3 : 1 and 20 : 1. Suitable carbonyl halides are COCI2, COF2, COCLF, COFBr, and COBr2, and suitable pentahalides are PCI5 PCI2F3, PF5, PBr5, and PF3Br2. Tetrahalorethanes specified are CCL4, CCI2F2, CCI3F, CFCI2 Br, CCI2Br2 Br2F2, and CF3CI, Examples are given of the preparation of some of the compounds and also of a cyclic process for the preparation of carbon tetrachloride by reacting carbon monoxide with chlorine to form phosgene, reacting phosphorous trichloride with chlorine to form phosphorus pentachloride, reacting the said phosgene and phosphorus pentachloride together to form carbon tetrachloride and phosphoryl chloride and reacting the phosphonyl chloride so formed with carbon monoxide to regenerate phosphorus trichloride.

Title: Improved method of and apparatus for thermal rock piercing
IPC: E21B7/14
Filed: 1951-12-13
Abstract: 697,373. Thermal rock piercing apparatus. UNION CARBIDE & CARBON CORPORATION. Dec. 13, 1951 [Dec. 28, 1950], No. 29164/51. Class 68(i) In a thermal rock piercing apparatus in which the heating device such as a blowtorch is progressively advanced into the borehole as the material ahead of it is burnt away, automatically operated means are provided so that when the progress of the tool is impeded by an obstruction such as a collar in the borehole formed through incomplete removal of material ahead of the tool; then, after a predetermined time delay, the heating device is withdrawn a predetermined distance away from the obstruction and maintained in this position for a given period of time, whereupon the device is again advanced towards the zone of the obstruction which should now have been removed, so permitting normal advance of the heating device, or if the obstruction remains then the above cycle of operations is repeated until it is removed. A high-speed MF and a low speed MS motor can be separately used to rotate the winch PG about the drum 30 of which is wound the cable C supporting the tool B, and said motors and winch are mounted on a, pivoted block 31 the total weight of which is such that it is slightly exceeded by the tension in the cable when the tool is freely suspended plus the upthrust of a spring 45. On the blow torch striking a collar D, the block tilts downwards so that the two coils E and N mounted thereon move with respect to a soft iron core 35, thus the induced current in the coil N is reduced causing the closing of a switch in the motor control circuit means 36, 37, 39 which if certain other switches have been set by the operator, result in the above sequence of operations. The blow torch can be lowered or raised in the borehole by either of the two motors under the manual control of the operator using the usual drum starter and a suitable relay system controlling the motors, or can be arranged to operate automatically so that on the torch encountering an obstruction it is raised after the suitable time delay by the high-speed motor to the predetermined distance whence, after a set interval, it can be lowered by either the slow speed motor, or by the high speed motor, to the' zone at which the obstruction was encountered, and from thence by the slow speed motor. If the torch is being lowered under the control of the operator, means are provided whereby the lowering motor is automatically stopped when the torch encounters an obstruction.

Filed: 1947-11-01
Abstract: 632,770. Control lever mechanism. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. Nov. 1, 1947, No. 29200. [Class 136 (i)] A device for actuating a brake cable or like motion transmitting means comprises a hand lever and a support in which one end of the hand lever is constrained to move along a straight line and a part of the lever intermediate of the two ends is constrained to move over a predetermined path whereby the hand lever is angularly movable relatively to the support. As shown, the support is in the form of a plate 2 fixed to a protuberance on a movable control column 1. The lower end of the lever 7 comprises two side plates 8, 8, disposed on either side of the plate 2. A pin 9 passes through a slot 4 in the plate and has its ends in the side plates 8, 8. A roller 10 connected to the cable I is mounted on a pin 13 in a straight slot 3 in the plate, the slot being substantially parallel to the control column 1. Another roller 12 is similarly mounted on a pin 28 between the plates 8, 8 and is in contact with a cam surface 6 in the periphery of the plate 2. A lug 16 is formed integral with one of the side plates 8 and has a screw-threaded hole engaged by a set-screw 17. Adjacent the set-screw is a detent 24 projecting from a disc 20 mounted in a bearing boss 21 rigid with the protuberance of the control column 1. A spring-loaded ball 26 carried by a knob 23 integral with the disc 20 co-operates with one of two depressions 25 formed in the boss 21. When the lever 7 is in the off position as in Fig. 3 the set-screw 17 projects below the disc 20. On actuation of the lever 7 the pin 9 moves towards the upper end of slot 4 and the set-screw moves up to the position shown in Fig. 4. When the knob 23 is in the position shown in Fig. 3 the brakes can be released or applied. If it is desired to leave the brake fully applied the knob 23 is moved over to the position shown in Fig. 4 so that the detent 24 lies across the path of the screw 17.
Patent GB-692165-A (GB)
Title: Improvements in or relating to substituted diketones of heterocyclic compounds and the production thereof
Filed: 1950-11-29
Abstract: The invention comprises compounds of the formula <FORM:0692165/IV (b)/1> p  wherein the substituent radicals R and R1 represent an alkyl, cycloalkyl or aralkyl radical and one of the radicals R and R1 contains a minimum of three carbon atoms.  Radicals mentioned as one substituent are normal and branched propyl, butyl, amyl, hexyl and octyl radicals, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, benzyl, phenethyl and phenyl-propyl radicals, the other substituent being such a group or a methyl or ethyl group.  If R contains more carbon atoms than R1, the compounds are obtained by reacting 1,3-dialkyl ureas, acetic anhydride and cyanoacetic acid to produce a cyano-acetyl urea derivative of formula R-NH-CO-NR1-CO-CH2CN. (Mixed isomers are formed if R and R1 are very similar.) This derivative is then cyclized by adding alkali to give a pH of at least 7 followed by heating to 40 DEG  to 100 DEG  C.  Alternatively, where R may be smaller than R1, a monoalkyl urea is reacted with acetic anhydride and cyanoacetic acid, the resulting N-alkyl-N1-cyanoacetyl urea is cyclized using alkali and the 1 - alkyl - 6 - amino - 1,2,3,4 - tetrahydro - 2,4 - pyrimidinedione obtained is converted to its alkali metal salt and reacted with an alkyl, cycloalkyl or aralkyl halide or sulphate to give the disubstituted derivative.  In examples: (1) 1 - n - propyl - 3 - methyl - 6 - amino - 1,2,3,4 - tetrahydro-2,4-pyrimidinedione is prepared by reacting n-propylurea, and cyanoacetic acid in acetic anhydride, heating the resultant N-propyl-N1-cyanoacetyl urea with alkali to give 1 - n - propyl - 6 - amino - 1,2,3,4 - tetrahydro - 2,4 - pyrinidinedione and reacting the latter with dimethyl sulphate and alkali; (2) 1-n-propyl - 3 - ethyl - 6 - amino - 1,2,3,4 - tetrahydro-2,4-pyrimidinedione is obtained by reacting N-propyl-N1-ethyl-urea (prepared from ethyl isocyanate and n-propylamine), cyanoacetic acid and acetic anhydride and, by treatment with alkali, cyclizing the resulting N-n-propyl - N1 - ethyl - N1 - cyanoacetylurea.  Similarly to (2) are prepared compounds of the above general formula where (3) R,R1=propyl; (4) R=isopropyl, R1=methyl; (5) R=isopropyl, R1=ethyl; (7) R=butyl, R1=ethyl; (8) R,R1=n-butyl; (10) R=hexyl, R1=ethyl; (11) R=cyclohexyl, R1=ethyl; (12) R,R1= benzyl; (13) R=g -phenylpropyl, R1=ethyl.  The substituted urea starting material is obtained by reacting the appropriate isocyanate and the alkyl- or aralkylamine. Similarly to (1) are prepared the compounds where (6) R=n-butyl, R1=methyl; (9) R=isobutyl, R1=methyl; (14) R=methyl, R1= n-propyl; (15) R=ethyl, R1=n-propyl.  As an intermediate is also prepared 1-benzyl-6-amino-1,2,3,4 - tetrahydro - 2,4 - pyrimidinedione by reacting benzylurea, cyanoacetic acid, acetic acid and anhydride to give N-benzyl-N1-cyanoacetylurea which is cyclized by heating with alkali.

Title: Improvements in or relating to releasing devices
IPC: F42B22/00
Filed: 1945-11-05
Abstract: 624,852. Automatic catches. FRIEDER, L. P. Nov. 5, 1945, No. 29313. Convention date, Nov. 23, 1944. [Class 44] [Also in Groups XXI and XXXIII] A device for automatically releasing, e.g. a mine from a cable, or a parachute from its load, comprises two co-axial, telescoping members, a compression spring and a catch to hold them together, relatively rotatable means for disconnecting the members including relatively rotatable members adapted to be operated by being drawn through.water, and means actuated by the relative rotation of one of the latter members with respect to the other one to release the catch. As shown in Fig. 1, a pin 28 to which is attached a cable 34 is retained in a housing 13 by two rollers 30 engaging in grooves 29 in the pin 28 and held against the top of the housing 13 by a compression spring 31 acting between the pin 28 and the base of a U-shaped member 20. Abutting against the underside of the member 20 is a piston 5 sliding in a socket in a shaft 4 to which is attached a propeller 2 and the load (not shown). A propeller 1 of the opposite hand is attached to a tube 3 rotatable on the shaft 4 and having V-notches 7 at the top in which rest the ends of a pin 6 attached to the piston 5 and protruding through slots 11 a in the shaft 4. When the device moves through water the propellers 1, 2 rotate in opposite directions, the first quarterrevolution of one with respect to the other causing the pin 6 to ride up out of the notches 7 into a space 8, and the piston 5 to push the U-shaped member 20 upwards against the pressure of the spring 31. When grooves 22 in the arms 21 of the member 20 move into alignment with the grooves 29, the rollers 30 roll into them, the member 20 being prevented from falling again with the piston 5 by a spring-loaded pin 24. The compression spring 31 then expands, pushing the pin 28 free of the housing 13. The Specification as open to inspection under Sect. 91 comprises also the device shown in Fig. 5 (Cancelled) arranged to be operated by impact. When the load 40 strikes the ground the pin 56 continues to move downwards in the part 66 of a housing 41 until rollers 63 are forced by spring-loaded plungers 61 into grooves 52 in members 50, a spring 55 being compressed during this movement. The spring 55 now expands, pushing the pin 56 free of the housing 41. This subject-matter does not appear in the Specification as accepted.
