Filed: 1939-06-27
Abstract: 530,554. Shearing; making sheets. BLACK, G. E. June 27, 1939, No. 18703. [Classes 83 (ii) and 83 (iv)] Metal sheet feeds.-Flat, cut to length and width, steel sheets are produced from continuous stock having untrimmed edges but being of substantially uniform width by passing the stock through a straightening device and through guides to a stop. The strip is sheared transversely and the cut off portion is forwarded through guides to side trimming cutters whence the finished sheet is delivered tc a stacker. A coil 32 is raised from a pit to rails 35 and passes thence to rolls 42 that support it during uncoiling. The free end passes over a roller 45 through feed rolls 3E and a straightener 46 and over a ramp 52 that facilitates the formation of a loop 140 when the forward end of the sheet is arrested during cutting off by shears 56. Auxiliary feed rolls 54 are brought into operation when the end of the strip leaves the rolls 36. Chain conveyers 22, 24 carry the sheet along between an adjustably fixed guide 14 and a movable guide 16 operated by linkage actuated by a solenoid-controlled fluid pressure cylinder 96 to clamp the sheet between the guides during severance. An adjustable spring effects the return. The solenoid is actuated by the sheet passing under a flag switch 60, Fig. 9, which also starts the motor driving the shears 56 and controls a half-revolution motor operating the stop 62, through crank and connecting rod 120. The switch and stop are mounted on a longitudinally adjustable carriage 1'24. The side guides are formed with hold-down members that prevent the sheet from buckling on contact with the stop 62. Scrap cutters deliver waste to a bin 152. Caterpillar conveyers 146, 148 deliver the severed lengths through trimming cutters 145 and onto a roller table 218 provided with adjustable side guides. Feed rolls 160 deliver to an inclined piling table where they rest on rails being aligned by side guides and an end stop 200. The piling table is pivoted at 204 and may be raised by pneumatic means 212 to a horizontal position to facilitate removal of the piled sheets. The roller table 28 is pivoted at 162 to permit removal of the scrap bin.

Abstract: 871,719. Doors for resisting fluid pressure. LEEDS & BRADFORD BOILER CO. Ltd., and PICKARD, H. M. H. Sept. 12, 1958 [June 14, 1957], No. 18855/57. Class 123(1) [Also in Group XXV] A cylindrical pressure vessel such as an autoclave or vulcaniser which is partially sunk in a pit has a hinged door which is arranged to lift vertically as it begins to open so that its lower edge clears the edge of the pit. The lifted door can then be swung open over the floor in which the pit is sunk whereby the size of the pit in front of the door can be much reduced. As shown, the door 1 is carried by a bracket 2 to which is affixed hinge bosses 2a, 2b within which is secured a hinge pin 3. The hinge pin is supported in hinge bosses 4, 8 secured to a bracket 5 fixed to the mouthpiece 6 of the vessel. The boss 4 constitutes a pneumatic or hydraulic cylinder and the lower end of the pin 3 is fitted with a piston 7 operating in the cylinder. When the door is opened a few degrees it actuates a valve (not shown) to admit a pressure fluid under the piston 7 whereby the pin 3 is raised and lifts the door. As the lower edge of the door reaches the level of the floor a helical guide 9 welded along the pin 3 contacts a peg 10 and causes the door to swing open over the floor. To close the door the pressure fluid valve is opened and the guide means 9, 10 swings the door closed as it drops down into its lower position when it is almost shut. It can then be swung straight into the mouth of the vessel and sealed. In a modification guides are secured to the top of the door opening and the pit edge to prevent the moving door from coming into contact therewith.

Filed: 1956-06-18
Abstract: The invention comprises phenthiazine compounds of the formula: <FORM:0808959/IV (b)/1> and acid addition and quaternary salts and addition compounds thereof, (Rz is a hydrogen atom or a lower alkyl of one to six carbon atoms, or an aryl or araliphatic group, Y and Y1 are respectively a hydrogen or halogen atom or a lower alkyl, alkoxy or aryl or aryloxy group, the phenthiazine nucleus may carry one or more substituents in addition to Y and Y1 and one or more of the carbon atoms of the piperazine ring may be methyl substituted), and methods for their preparation by reacting a phenthiazine bearing Y and Y1 groups and substituted at the 10-position by a group P with a compound Q, Q and P being such that the reaction leads to the introduction of <FORM:0808959/IV (b)/2> into the 10-position, A1 being -CH2.CH(Me).CH2-or group reducible thereto, and R2 being hydrogen, an alkyl, aralkyl or aryl group, or group convertible thereto.  Specified processes are (a) reaction of a phenthiazine substituted at 10-position by -A1X (X is the residue of a reactive ester) with piperazine bearing R2 on a nitrogen atom; (b) reaction of a 10-unsubstituted phenthiazine with a compound of formula <FORM:0808959/IV (b)/3> and (c) reaction of a phenthiazine of general formula: <FORM:0808959/IV (b)/4> with an amine of formula R2NH2.  An alternative method of formation is the cyclization of compounds of the formula: <FORM:0808959/IV (b)/5> preferably in a substituted lower aliphatic acid amide as solvent, and in the presence of a dehydrohalogenation catalyst, e.g. copper powder.  The processes are preferably effected with an alkaline condensing agent such as an alkali metal or its hydroxide, hydride, amide or alcoholate, and are followed, if necessary, i.e. when A1 and/or R2 is a "convertible" group, by the conversion step, e.g. reduction of -CH2.CH(Me).CO- to -CH2.CH(Me)CH2-with lithium aluminium hydride, likewise -COR3 to R2 (R3 is alkyl, aralkyl or aryl), or when R2 is to be hydrogen, elimination of -CH2C6H5, -C6H5, -COOR4, or -CON(R5)2 respectively by hydrogenation, nitrosation and fission, or hydrolysis (R4 and R5 are hydrocarbon groups).  In examples: (1) 3-chlorophenthiazine and sodamide are refluxed in xylene with 1 - chloro - 2 - methyl - 3 - (41 - methyl - 11-piperazinyl) propane to give 3-chloro-10-(3-[41 - methyl - 11 - piperazinyl] - 2 - methylpropyl) phenthiazine isolated as its di-acid maleate and characterized as the di-picrate; similarly (2) to (4) are prepared the 3-methyl-, 3-ethyl-, and 3-methoxy analogues; (5) 3-(31-chloro-101-phenthiazinyl) - 2 - methylpropyl p - toluene sulphonate and 1-ethylpiperazine are heated together to yield 3-chloro-10-(3-[41-ethyl-11-piperazinyl]-2 -methylpropyl) phenthiazine isolated as its di-acid maleate; (6) as in (5) but using piperazine to give the di-acid maleate of 3 - chloro - 10 - (3 - [11 - piperazinyl] - 2 - methylpropyl) phenthiazine.  The compounds are useful as anti-emetic agents. Specification 632,277, 789,703 and 789,811 are referred to.
