Title: Improved portable punch and die holder
IPC: B21D28/24
Filed: 1951-08-31
Abstract: 687,555. Punching. WALES-STRIPPIT CORPORATION. Aug. 31, 1951 [Jan. 26, 1951], No. 20568/51. Class 83 (iv). In a punch and die holder for a punching machine the punch, punch guide and stripper assembly are supported by a lifting spring independent of the assembly. A punch P adjustable by a nut 52 is withdrawn in a stripper 50 guiding the punch by springs 58 limited in action by a stop-pin 60. The stripper 50 is guided in a bush 30 in a C-frame 20 housing a die D and adjustably secured to a slotted bed by bolts 44. To support the punch assembly relatively to the die an arm 70 urged by a spring 85 is controlled by a screw 80 engaging the frame. By adjustment of the screw 80 the lever 70 varies the position of the punch and stripper relatively to the die. When the lever 70 is depressed by the screw 80 the punch assembly falls by gravity to facilitate alignment of a centre point on the punch with indentations in the workpiece. In a modification, Fig. 11, not shown, the die can be removed from the bottom of the frame. The work may be positioned by gauging stops, Fig. 9, not shown, or by conical centre on the punch. By adjusting the nut 52 engaging a screwed end of the punch the compression of the springs 58 may be varied.

Title: An improved synchronous electric motor
IPC: H02K19/14
Filed: 1927-08-04
Abstract: 280,858. Schneider et Cie. Nov. 17, 1926, [Convention date]. Alternating - cur - rent motors; motors with unwound iron armatures; driving- arrangements; coils and conductors. - The rotor of a single-phase or polyphase synchronous motor having the property also of asynchronous run - ning consists in one part of perforated laminae, as used in asynchronous motors, and in another part of laminae which are both perforated and notched so that when assembled they form two pole-pieces in a squirrel-cage rotor. In the form shown the plates C, are of soft iron or magnetized steel, and are notched to form two polepieces C<1>, C<2>. A second set of plates B is of the kind used in the rotors of asynchronous motors. Both sets of plates are provided with slots b, c, in which there is cast a squirrel-cage winding D, preferably of aluminium which forms also the ends D', D<2> of the cage. The field magnet of the motor is formed like the stator of an asynchronous motor, the coils being connected in an arrangement having a neutral point. The squirrel cage may be made in the known manner by riveting copper rods upon two rings of the same metal, or by making an electrolytic deposit. The armature slots may run parallel to the shaft or may be curved so as to have a helical form. The length of the stator may be equal to the length of the rotor, or it may be reduced to the length of the pole-pieces and provision made for displacement of the rotor relatively to the stator, after starting, for bringing the stator opposite the pole-pieces. Motors of the kind described may be used for the actuation of Baudot type telegraphs, teletype machines, stroboscopic, and television apparatus. In the case of a number of wheels which are to be driven in constant angular relationship by motors having different synchronous speeds, a train of gearing, giving a multiplication of speed of 2p may be interposed between each motor and the corresponding wheel, 2p being the number of poles of the motor.

Abstract: 387,363. Coating-compositions; effecting chemical reactions by radiations. DU PONT DE NEMOURS & CO., E. I., Wilmington, Delaware, U.S.A. July 24, 1931, No. 21160. Convention date, Feb. 28. [Classes 1 (i) and 95.] Products useful as constituents of coating- compositions are prepared by polymerising halogen 2-butadienes 1- : 3, which are obtainable as described in Specification 387,325, [Group IV]. The halogenbutadienes polymerize slowly when allowed to stand in the absence of light and air, but polymerization may be accelerated by the application of heat and pressure, by the action of natural or artificial light, and by the presence of oxygen or air or a catalyst, e.g. benzoyl peroxide, oxidized turpentine, sodium peroxide, lead peroxide, or hydrogen-peroxide. Examples 1-21 describe the polymerization of chloro-2-butadiene-1 : 3 under various conditions as indicated above. The polymerization may be retarded or controlled by addition of any of the following substances, called inhibitors : pyrogallol ; catechol ; guaiacol; hydroquinone; p-hydroxydiphenyl; phenol; benzoquinone ; alpha-naphthoquinone; tetraphenylhydrazine ; m - toluylenediamine thiodiphenylamine ; phenyl alpha- or #-naphthylamine ; diphenylguanidine; diphenylamine dibenzylamine ; aniline ; piperidine ; pyridine dimethylaniline ; quinoline ; ethylenediamine di- or tri-butylamine ; triethylamine ; heptylamine ; benzidine ; nitro- or trinitro-benzene butyl- or benzyl-mercaptan ; thioacetic acid ; thiobenzanilide ; thiophenol ; thiocresol ; methyl or ethyl sulphide ; n-propyl or allyl sulphide ; n-butyl or n-heptyl sulphide; benzyl or diphenyl sulphide ; methyl n-propyl or nbutyl disulphide; ethyl thioacetate ; diethyl dithiooxalate ; ethyl ethylxanthate ; thioacetamide; thio-#- naphthol ; ethyl selenide ; iodine, or bromine. Examples 22-34 describe the polymerization of chloro-2-butadiene-1 : 3 in the presence of an inhibitor. The polymerization may also be effected in the presence of a volatile solvent capable of dissolving the halogen butadiene and its polymer, e.g. benzene, toluene, xylene, cymene ; diethyl ether, chloroform, carbon tetrachloride ; turpentine, ethylene chloride, pyridine, or carbon bisulphide. Examples 35-41 describe the polymerization of chloro-2- butadiene-1 : 3 in the presence of such a solvent, giving solutions which may be used as coating or impregnating compositions. Examples 56 and 57 describe coating compositions comprising solutions prepared as in examples 35-41 and containing (example 56) titanox and a little phenyl-#-naphthylamine, or (example 57) carbon black and a little phenyl-#-naphthylamine which may be replaced by any other of the usual rubber-antioxidants ; reference is made also to the use of the following pigments and fillers: lithopone, zinc oxide, white lead, chrome orange, iron oxide, Prussian blue, red lakes, whiting, asbestine and silica ; the compositions may contain also an acid-acceptor, e.g. sodium oleate.

Abstract: 1,213,434. Packaging. JOHN LEWIS Inc. 25 April, 1969 [9 Oct., 1968], No. 21317/69. Heading B8C. A method of packaging a series of flat wooden sticks 46, or the like, comprises the steps of axially tensioning a longitudinally folded strip of flexible material such as a paper tape 6 having a series of spaced punched holes 18 on both sides of the fold to accept the elongated articles snugly without tearing the tape, inserting each article into a pair of corresponding holes 18 so that the plane of each article is parallel to the fold line of the strip, and unfolding the strip to a substantially planar condition while maintaining the axial tension. As shown, the folded paper tape 6, passes between punch and die wheels 10, 12 which are mounted upon a table 4 and punch out the two series of holes 18, passes around a spring-loaded idler wheel 20, and is drawn along an arcuate guide 22. The latter is pivoted to the table 4 at 32, has a vertical guide wall 26 with an upper inverted channel portion 24, and is urged clockwise in to its limiting position, Fig. 1, by a spring 38. A split rim conveyer wheel 50 has axially aligned slots 51 which continuously accept sticks 46 from a hopper 48 complete filling being ascertained by a reserve magazine 70. The wheel 50 rotates under spring pressed pressure plates 72, 74 to deliver the sticks to a stick insertion station where the top point of the wheel 50 coincides with the series of holes 18 in the tape, the projecting ends of the sticks, at one side, being pushed away from the guide 22 by an angled portion 87 of the table before reaching the insertion station. Immediately after the termination of the support wall 26 of the guide 22 the sticks contact a guide 88 with a projection 94 to be pushed fully home into the tape 6, a freely rotatable wheel 96 providing back-up for the tape 6. The latter then passes over idler pulleys 98, 104, and a tensioning pulley 100, and is wound, with constant tension, on to a spool 122 which is friction driven, through a rubber tyred wheel 120, from an electric motor and gear-box 110 which also drives the conveyer wheel 50 having an internal chain 56 which drives a sprocket 58 secured to a shaft 60. A sprocket 62 mounted on the shaft 60 drives, through a chain 69, a further sprocket 66 whose shaft 68 drives the punch and die wheels 10; 12 through right angle gearing, not shown.
