Filed: 1926-01-22
Abstract: 252,668. New Process Multi-Castings Co., (Assignees of Wood, J. R.). May 29, 1925, [Convention date]. Moulding-machines; flasks.- Machines of the roll-over type have means for pressing and jarring the cope and drag, for drawing and swinging aside the pattern and for assembling the finished mould. The cope 40 is mounted on members 34, 39, Fig. 5, trunnioned in slides 18, 19 which are adapted to move vertically on pillars 11, 14. A bolt 55, Fig. 6, is arranged in the slide 19 to hold the cope in the position shown in Fig. 5 or in the inverted position. A pattern-plate 47 is arranged to swing and move a limited distance axially on a headed pin 44 carried by the member 34. Filling boxes 88, 89, Fig. 1, are pivotally carried by the slides 18, 19. A counterbalanced pressure head 72, Fig. 5, is trunnioned to yokes 16, 15 on the pillars 11, 14 which also carry hooks 20, 21 for supporting the slides 18, 19 and cams 24 for holding the hooks out of action. In use the plate 47, drag 54, and filling box 88 are moved into position over the cope 40 which is held up by the hooks 20. The head 72 is swung aside, the drag is filled with sand, the head 72 brought into position as shown in Fig. 5 and air is admitted to the cylinder 65, by a valve 71, Fig. 1, which acts automatically, first to press and then, if desired, to jolt the drag a definite number of times. The table 67 is then lowered, the head 72 and box 88 are swung aside, a bottom board is placed on the drag and secured by clamps 84 carried by the cope. The bolt 55 is then withdrawn, the cope &c. inverted, the box 89 swung into position, the cope is filled with sand pressed and jolted in the manner of, but preferably not to the same extent as, the drag, as described in Specification 253,453. The clamps are then disengaged and the drag lowered away from the pattern plate 47 which is thus also drawn from the cope-mould which is supported in the cope by members 86, Fig. 5, as described in Specification 252,669. The plate 47 is then swung aside, the drag lifted by the table 67 and attached to the cope by means of a latch. The members 86 are finally withdrawn and the assembled mould halyes on the bottom board are lowered away from the cope and drag. Springs 28 are provided to give a quick downward movement to the flask in jarring. In pouring the mould may be held together by a jacket as described in Specification 252,670. The trunnions of the members 34, 39, Fig. 5, are provided with roller and ball bearings 30, 36.

Title: Improvements relating to aiming means of guns
IPC: F41G5/08
Filed: 1951-01-25
Abstract: 680,883. Ordnance; training and elevating. AKTIEBOLAG BOFORS. Jan. 25, 1951 [Jan. 27, 1950], No. 1955/51. Class 92(i) The power elevating means 74 and power traversing means 67 of a gun 50 are controlled by one or more control devices, such as a joystick 12, in such manner that the speed of the gun in azimuth corresponds to the displacement of the control from a neutral position, and the position to which the gun moves in elevation corresponds to the displacement of the control in elevation. Any azimuthal movement of the device shown results in a signal passing through a cable 36 to a unit 61 containing a detector with a frequencytransmission network and an amplifier. This unit is connected by a cable 62 to an electro-hydraulic control device 63 coupled to the starting arm 65 of the traversing gear, whose shaft 68 drives the gear platform 57. The arm 65 is also connected to a synchronous element 66 from which a cable 81 passes back to the unit 61. The signal in cable 62 corresponds to any difference between the positions of the control device and the starting cam 66; thus the speed of the platform depends upon the position of the control. The elevating mechanism also has associated with it similar devices comprising a detector and amplifying unit 69, electrohydraulic control device 71, cam 73, and output shaft 75, but in this case the synchronous element 79 is actuated by gearing from the shaft 75. By this arrangement the signal in the cable 70 between the unit 69 and device 71 corresponds to any lack of correspondence between the control 12 and the elevating shaft 75. Filters associated with the units 61, 74 result in an additional traversing movement of the gun when the control is moved and in a lag in the elevating movement of the gun. Details of the filters appear in Figs. 2 to 6 (not shown).

The sleeve 1 is made of synthetic material. A diaphragm 8 can be fixed by adhesive to the pole plate 3 before assembly in the sleeve 1. If the diaphragm has a reinforced edge or an upturned locating rim it can be accommodated in the overhanging upper rim of the sleeve. A disc 15, located by adhesive, secures the assembly axially. The core 5 is hollow in register with a pad of damping material 20 in the securing disc 15. Instead of conforming to the circular edges of the pole plates the inner shouldered surfaces of the sleeve 1 may effect location by means of inwardly directed studs. Since it is desirable for the pole plate 4 to be of smaller diameter than magnet 2 the plate 4 may be located by a few radially directed lugs. The securing disc 15 may have an upwardly directed skirt 16, Fig. 4, and a tubular central portion 21 to enclose a back cavity and constitute a pressure transducer. The back cavity may be vented through matching apertures in the skirt 16 and side wall of the sleeve 1. To form a capsule for a telephone earpiece or mouthpiece, the sleeve 1 may be constituted by the inturned portion 31, Fig. 5, of a capsule casing 32. The bottom cover 35 provides the damped vent 21. While a securing disc fixed by adhesive is shown beneath the bottom pole plate, the assembly may be secured by deforming the depending edge of the sleeve 31 over the peripheral edge of the pole plate, Fig. 6, not shown.

Title: Manufacture of new piperidyl alkyl ketones
IPC: C07D211/32
Filed: 1953-01-26
Abstract: The invention comprises ketones of the general formula <FORM:0732584/IV (b)/1> in which R1, R2, R3 and R4 are alkyl groups of 1 to 4 carbon atoms, and their acid salts.  They are made by reacting a 1-alkyl-1-benzyl-4 - (31,41 - dialkoxy - phenyl) - 4 - cyano - piperidinium halide with an alkyl magnesium halide, the alkyl group of which corresponds to R4 above, decomposing with water, ammonium chloride or dilute acid, and splitting off the benzyl group with activated hydrogen.  In the example, 1 - methyl - 1 - benzyl - 4 - (31,41-dimethoxy - phenyl) - 4 - cyano - piperidinium chloride is ground with a Grignard solution prepared from magnesium, ethyl bromide and ether, and the reaction product is decomposed with ice. After further treatment, the quaternary ketone chloride separates as an oily layer which is debenzylated in methanol and water by treatment with palladium-carbon and hydrogen.  After filtering, the base is obtained by adding ammonia.  The starting material is prepared as follows: homoveratric acid is heated with sodium hydride and b -chloroethyl - methyl - benzylamine.  The product is decomposed with water and dilute acid and alkali added to precipitate N-methyl-N-benzylaminoethyl-3,4-dimethoxy benzyl cyanide.  This is reacted with sodamide and then with ethylene chloro-bromide and the mixture decomposed with ice.  Specification 591,992 is referred to.

Abstract: 1,086,501. Stapling machines. E. T. RUSE. April 20, 1965 [Jan. 20, 1964], No. 2491/64. Heading B4C. A stapling apparatus comprises a first piston 52 adapted to form a blank into a staple and a second piston 56 adapted to drive the formed staple into a workpiece, the operation of the two pistons being effected in timed relationship. The first piston 52 is slidably mounted in a cylinder 11 secured to a body portion 12 of the apparatus and connected to a fork member 54 having a wire shearing blade 70 and adapted to co-operate with an anvil 72 for forming the staple; the blade co-operates with a cutting bush 44. The second piston 56 is slidably mounted within the piston 53 and is connected to a driving blade 57 guided in slots 58 formed in the forked member 54. A wire feeding carriage 25 located in a recess 16 is provided in the body 12 and is actuated by means of a piston 39. An operating wire is fed from a drum and an end is inserted into a slot 14, through the carriage 25 and bush 44 across the anvil until it abuts a stop plug 73. Compressed air is then fed via a port (59, Fig. 3) so that the piston 52, together with the fork 54 moves downwardly thereby causing the blade to sever a length of wire. Continued downward movement of the fork then bends the wire into a staple over the anvil, and, simultaneously, causes a pawl 89 holding a carrier 77 for the anvil to be released. Compressed air is then fed via a port 50 to act on an impact piston 51 which moves the piston 56 downwardly so that the blade drives the staple into a workpiece, the anvil being moved out of the way of the blade by the co-operation of mating cam surfaces. The pistons are then returned to their upper position by feeding air through a port 69 and air is then fed to the piston 39 causing the feed carriage 25 to move a further length of wire up to the stop 73. The end of the wire, when initially fed into the slot 14, may be held by means of a piston 18 controlled by a pushbutton actuated valve 21. In modifications, the impact piston 51 and anvil carrier may be dispensed with and the cylinder 11 may have a square outer shape instead of being formed from a tube 48. Hydraulic liquid may be used instead of compressed air.
