Title: Improvements in machines for stringing dies, for use in wiredrawing machines
IPC: B21C1/04
Filed: 1923-05-24
Abstract: 215,588. Western Electric Co., Ltd., (Western Electric Co., Imc.). May 24, 1923. Drawing wire.-An apparatus for threading drawing-dies on wire comprises a pair of drums of the same diameter, one stationary for the reception of the threaded wire, the other rotatable in order to draw the wire through successive individual dies. The wire is first pointed by rolls 82, Fig. 1, driven bv a shaft 16 chain-driven from a motor shaft 12. The pointed wire is passed through the first die 85 seated in a pivoted holder 55, and is then clamped in a gripper 29 mounted' in a peripheral recess in a drum 28, Fig. 3. The drum is rotated bv a worm on the shaft 16 through an expanding ring clutch 23 which is actuated by a treadle 57, Fig. 2, the clutch being held in the engaged position by linkage 76, 72 controlled by a wedge 68 on a spring-pressed rod 65 which is released and urged upwards when the treadle is actuated. On the required length of wire being drawn, the rod 65 is depressed by the treadle 69 to disengage the clutch. The coiled wire is then passed on to the stationary drum 36, Fig. 3, the threaded die 85, Fig. 1, being removed from the holder and positioned by one of a series of forked stops 39 which are pivoted in blocks 40, these blocks being locked' in a circular T-slot 38 round the flange of the stationary drum, at angular settings given by a scale 100. One block is provided for each die to be threaded. The stops 39 are normally spring-pressed into positions perpendicular to the drum axis, but may be held' in contact with the stationary drum by hand trip levers 45. The first die being thus positioned, the drawn portion of the wire is again pointed and passed through the second die which is similarly seated in the holder 55. The wire between the first and second dies is looped round an arm 63, Fig. 2, so that when the clutch has re-engaged to draw the wire through the second die, the taking up of the slack actuates the arm 63 thereby depressing the rod 65 and so disengaging the clutch. The length between the threaded dies is thus determined automatically. The die-stop 39 for the first die is then tripped, the stop corresponding to the second die being brought into position. A constantly applied brake 51 is provided for the rotary drum, and a handle 52 for bringing the gripper into the initial position is also fitted. Successive dies are similarly threaded, the wire as it is drawn passing under a spring pressed arm 49 which prevents the return of the coiled wire on to the rotary drum. The wire and threaded dies coiled on the stationary drum may finally be removed and strung on the wiredrawing machine.

Title: Improved manufacture of organo-siloxanes
IPC: C08G77/06
Filed: 1946-05-09
Abstract: A process of preparing new synthetic products from silanes having two mono-valent hydrocarbon radicals, which need not be the same, attached to each silicon atom through carbon-silicon linkages, the remaining valences of the silicon atoms being satisfied by hydrolysable radicals which are attached to the carbon atoms through other than carbon-silicon linkages is characterized by co-hydrolysing a mixture of at least two of said silanes which differ with respect to the chemical composition of that portion of their molecules exclusive of said hydrolysable radicals and condensing the hydrolysis product to obtain a copolymer thereof.  The hydrocarbon radicals may be alkyl radicals; alicyclic radicals such as phenyl and mono- and poly-alkyl phenyls; naphthyl and poly-alkyl naphthyl; tetrahydronaphthyl and anthracyl; aralkyl radicals such as benzyl and phenylethyl; and alkenyl such as methallyl and allyl; and may be substituted by inorganic constituents such as halogen.  Where all the hydrolysable radicals are halogen, dioxane is the preferred solvent, and where all are alkoxy, dilute acid or alkali is used.  The products in some cases are hardened on heating.  In examples: (1) aqueous dioxane is added to a mixture of (C6H5), SiCl2 and (C6H5) (C2H5)SiCl2.  The liquid product hardens on heating; (2) a dioxane solution of (C6H5)(C2H5)S SiCl2 and (CH3)2Si(OC2H5)2 is hydrolysed by warming with aqueous dioxane; (3) (CH3)2Si(OC2H5) and (C6H5)2SiCl2 are hydrolysed and inter-condensed in dioxane solution; (4) a mixture of (C6H5.CH2)2SiCl2 and (CH3)2Si(OC2H5)2 is hydrolysed with 95 per cent ethyl alcohol followed by addition of water.  The oily product forms a thermoplastic resin on heating; (5) a product prepared from (C6H5.CH2) (CH3) Si(OC2H5)2 and ( (CH3)2Si(OC2H5)2 by hydrolysis with alcohol and HCl is a viscous oil forming a waxy resin on heating; (6) a viscous liquid is obtained by hydrolysing with alcohol and HCl a mixture of (C6H5)(CH3) Si(OC2H5)2 and (CH3)2 Si(OC2H5)2.

Abstract: 774,334. Control of A.C. motors. INVENTIO AKT.-GES. May 17,1955 [May 24, 1954], No. 14184/55. Class 38(3) A system for accurately levelling an electrically-driven lift at a desired floor comprises a dynamo-electric brake BM the squirrel cage rotor of which is coupled to the hoist motor AM and with its field winding excited in accordance with the difference between a voltage derived from a tachometer. generator T and a reference voltage which varies in a predetermined manner with regard to time. The tachometer generator is driven by the hoist motor and provides a voltage proportional to its speed, the reference voltage and,the speed-responsive voltage being supplied to an amplifier V the output terminals of which are connected to the field winding of the machine BM. To initiate retardation of the hoist motor, its rotor winding is connected to a high resistance so that the motor can produce the requisite torque at low travelling speeds. As shown, the reference voltage is derived from a capacitor 7 which is charged from a voltagedivider 1, 2, during full-speed travel of the lift and is discharged through a pentode 5 when the lift is to be retarded. The rate of discharge of the capacitor 7 is dependent upon the setting of resistor 14 in the control circuit of the pentode 5. The difference-voltage is applied to the control electrode of a pentode 10 which regulates thyratrons 11 in the excitation circuit of the braking machine. When the stopping-position is reached, the capacitor 7 is completely discharged through resistor 6 and a holding-brake H is applied. Other forms of the apparatus S for providing the reference voltage are described.
