Title: Improvements relating to can seaming mechanism
IPC: B21D51/32
Filed: 1945-09-21
Abstract: 617,072. Seaming. GEESON, R. E., PERKINS, C. W., and BLISS (ENGLAND), Ltd., E. W. Sept. 21, 1945, No. 24552. [Class 83 (iv)] In a seaming head mechanism for square or rectangular shaped cans, each seaming arm 10 is actuated by a bell-crank lever pivotally mounted on a follower arm 6 which is actuated by a follower cam 18 secured to the chuck 19, one arm 21 of the bell-crank being operatively connected to a pressure arm 14 associated with the seaming arm and the other arm 22 carrying a cam roll 26 engaging a seaming cam 27, the arrangement being such that the axis of the cam roll coincides with the pivotal axis of the follower arm when at the highest part of the cam. The seaming head casting comprises two cruciform members 1 and 2 secured by screws 41 and providing four pairs of axially spaced bearings 4 and 5. Between each pair of bearings is mounted a follower arm 6 having at one end an arm 6a carrying a roll 17 bearing on the follower cam 18 and at the other end an arm 6b extending in the opposite direction and having a boss 20 in which is rotatably mounted the bell-crank lever, having at one end an arm 22 carrying a cam roll 26 engaging a seaming cam 27 and at the other end an arm 21 carrying an adjustable screw 23. The arm 6b is heavier than the arm 6a so that centrifugal force tends to move it away from the chuck. Mounted within the central portion of the follower arm is a spindle 7 having at its lower end a seaming arm 10 which is angularly adjustable by means of serrations 12 and a nut 11 and at its upper end, a pressure arm 14 and a short arm 28 engaging a return spring 29 acting in the same direction as the centrifugal force. The adjustable screw 23 bears on the pressure arm 14 through a flat leaf-spring 24. In operation, the follower cam 18 acting on the follower arm roll 17 causes the bell-crank lever to follow the general outline of the can, while the seaming cam 27 acts on the arm 22 of the bell crank so that the screw 23 moves the arm 14, spindle 7 and seaming arm 10 so that the seaming roll 16 is pressed on to the work. Two of the follower arms have cam rolls 26 and the other two have cam rolls 26a, the rolls being acted upon by different seaming cams 27 and 27a for effecting first and second seaming operations.

Title: Improvement relating to train speed controlling systems
IPC: B60T7/12
Filed: 1920-09-02
Abstract: 154,564. Thomas, T. H. Nov. 21, 1919, [Convention date]. Fluid-pressure.-Apparatus for controlling trains by a speed-responsive device according to traffic conditions, such, for example, as described in Specification 155,369, is provided with an additional speed responsive device adapted to limit the speed of the train if the main device fails. The apparatus shown comprises a brake-pipe venting valve 17 controlled both by the main and additional speed governors 1, 3 through valves 22, 19. The valve chamber 15 of the valve 17 is under pressure from the pipe 16. The pressure air leaks through a port 31 in the piston 14 to the chamber 13, so that normally with the valves 22, 19 closed the valve is held in the closed position shown, by the spring 32. If the governor 1 fails through breakage or other cause, the spring 11 moves the shaft 10 and plate 12 sufficiently to the left to open the valve 22 as shown, and if thereafter the train-speed exceeds that for which the governor 3 is set, the contact 27 is broken and the valve 19 thereby opened. The reduction of pressure in the piston chamber 13 then causes the valve 17 to connect the brake pipe 18 to the exhaust port 30 and apply the brakes. The governor 3 may be directly connected to the vehicle axle so that it will be unlikely to fail.

Abstract: The invention comprises (4-biphenyl-pyridyl)-a -substituted carbinols of formula <FORM:0834336/IV (b)/1> in which X is a phenyl, substituted phenyl, alkyl, aralkyl or cycloalkyl radical.  They may be prepared by reacting a 4-biphenylyl-pyridyl ketone with a Grignard reagent of the formula X-Mg-Y, in which Y is a halogen atom, in an organic solvent at elevated temperature and subjecting the resulting mixture to mild hydrolysis.  The 4-biphenylyl-pyridyl ketones used as starting materials may be prepared by condensing isonicotinic acid chloride or nicotinic acid chloride, preferably in the presence of a condensing agent such as aluminium chloride, with diphenyl and hydrolysing the product.  The condensation step is conveniently carried out in an organic solvent, e.g. carbon disulphide, at a temperature between 40 DEG  and 150 DEG  C.  The ketones are converted as above to the carbinols using a Grignard reagent. Suitable halides for use in the Grignard reaction are, for example, phenyl bromide, m- and p-methyl phenyl bromide, p-methoxyphenyl bromide, o-, m- and p-chlorphenyl bromide, o-, m- and p-fluorophenyl bromide, dichlorophenyl bromide and lower alkyl and cycloalkyl bromides and iodides.  Suitable solvents for the Grignard reaction are diethyl ether, tetrahydrofuran, benzene, toluene, xylene and anisole and the reaction is conveniently carried out at the boiling-point of the solvent, preferably between 30 DEG  and 150 DEG C. The mild hydrolysis of the product may be carried out by an ammonium salt or by dilute acetic acid followed by dilute alkali. The compound may be isolated as the free base or as a crystalline salt by treating the free base with an acid such as hydrochloric acid.

Title: Improvements in or relating to electrical-measuring devices especially record-measuring devices

Filed: 1937-09-22
Abstract: 502,689. Current and volt meters. SIEMENS & HALSKE AKT.-GES. Sept. 22, 1937, No. 25740. Convention date, Oct. 24, 1936. [Class 37] A multi-range current and/or pressure measuring device, 'for example, a recording meter, the energy consumption of which is considerably greater than that of an indicating meter, is actuated without any additional energy drain on the circuit being measured by connecting the latter to the measuring mechanism through the usual switching means for varying the range and/or type (A.C. or D.C.) of current or pressure, and a linear amplifier. As shown, applied to a moving coil ammeter, the input to be measured is applied across terminals 16, 17 of a normal multi-range moving coil indicating instrument 12, provided in known manner with resistances and a rectifier controlled by a knob 13 for altering the range and class of current, i.e. A.C. or D.C., to be measured. When measuring current, the moving coil of meter 12 is connected in series by terminals 10, 11, 14, 15 with a measuring moving coil 7 carrying a vane 8 which in known manner controls a bolometer bridge 4 supplied with D.C. at terminals 5, 6, so that any change in the current being measured deflects the coil 7 to upset the balance of the bridge, a corresponding amplified current thereby being produced through a measuring moving coil 2 which actuates an ink recording stylus directly in synchronism with the movements of the indicating pointer of meter 12. The coil 7 moves until the potential drop across a resistance 3 is equal to that across a resistance 9, when the potential across the coil 7 is zero, thereby compensating for the insertion of the resistance of the coil in the circuit of the instrument 12. The resistances 3, 9 are so dimensioned that the current to be measured produces the necessary amplified current in the coil 2 to actuate the recorder. For measuring pressures, the coil 7 is connected in parallel with the moving coil of meter 12 and regulated by resistances such as 3, 9 to present infinite resistance in the branch circuit 10, 11. Modifications. The indicating instrument 12 may be dispensed with, the input to be measured being then connected through the range changing means directly to the coil 7. The bolometer amplifier may be replaced by a valve, optical or other D.C. amplifier and the apparatus may be used to actuate apparatus having a relatively large energy consumption other than a recorder, e.g. a relay, the response of which is variable.
