Title: Improvements in electrical measuring instruments
IPC: G04C11/00
Filed: 1937-06-08
Abstract: 502,168. Current and time measurements. BIERNAWSKI, W., and PANSTWOWE WYTWORNIE UZBROJENIA w WARSZAWIC. June 8, 1937, No. 15916. Convention date, June 8, 1936. [Class 37] Apparatus for measuring short intervals of time, for example, the time of flight of a projectile, comprises series - connected condensers CI, C2 with a ballistic galvanometer G connected between them and to a variable resistor r2, the condensers discharging differentially through the galvanometer. The galvanometer is calibrated for a predetermined known time interval by partially discharging one condenser while fully discharging the other, the residual charge on the second condenser equalling the difference in quantity of the two condenser charges to the time of stopping the discharge of the first condenser. Under these conditions a zero deflection of the instrument is given for a predetermined time interval, while for measurement purposes the quantity remaining is indicative of the difference in time intervals between the known and unknown intervals, this quantity deflecting the galvanometer movement in one direction or the other. An auxiliary battery, E2 resistors r4, r3, and switch U are provided for adjusting the zeropoint. The charging circuit A comprises a main battery E1, milliammeter mA, and variable resistor r1, measurement being effected by breaking the circuit first at P1 and then at P2, the interrupter P3 being short-circuited. An absolute measurement can be performed, instead of the differential one described above, by opening P2 and breaking the circuit first at PI and then at P3.

In a stator winding machine wherein the stator is prevented from moving angularly but is movable axially on two guide cylinders, the wire guides are disposed between the adjacent ends of the cylinders and are angularly moved between the stator movements. The stator, denoted by dotted line 31 in Fig. 1, is held in a clamp 32 on a slide 29 arranged to reciprocate on the base 1 the ends 3, 4 of which carry sleeves 5, 6 having splines 52 spaced and sized to enter the stator slot mouths. Sleeve 6 is so mounted on member 9 that it can be slid away from sleeve 5 to allow the stator to be placed in position or removed. Sleeve 5 surrounds a sleeve 18 carrying a cup 15 in which are guides 21 with bores 28 for the passage of wires 27, equal in number to the stator poles, fed through the sleeve 18 which is coupled to a hollow shaft 146 (Fig. 7) angularly moved through racks and gearing from lever 126 having a peg 111 in the cam slot of drum 107. Each wire is fed a predetermined number of times, dependent on the speed of rotation of discs 193, 195, 196, 197, into each of four pairs of slots in turn, the corresponding angles through which the shaft 146 is rotated being determined by the position of roller 129 in the slot of lever 126, the roller 129 being on a rack 131 (which drives shaft 146 from gearing including pinion 137) vertically moved in stages through the distances between discs 193, 195, 196, 197, as soon as these discs have rotated through a large enough angle to bring a slot in the disc periphery opposite a catch on a stirrup embracing the rack 31. The cam drum 107 is an extension of the drum 106, the peg 110 of which causes reciprocations of the stator slide 29, the drum being gear connected to the pulley 114 driven by a motor which also rotates the discs 193, 195, 196 and 197 (equal in number to the slot pairs per pole) through a large reduction gear and a pawl and ratchet. Arrangements are made to ensure that the movements of shaft 146 exactly correspond to the pitches of the coils. Specifications 419,917 and 862,055 are referred to.

Patent GB-229561-A (GB)
Title: Improvements in pressing or punching apparatus
IPC: B21D28/30
Filed: 1924-07-11
Abstract: 229,561. Shields, T., (Timken Roller Bearing Co.). July 11, 1924. Bearings.-A punching or pressing machine especially adapted to punch roll pockets in the cages of roller bearings includes means for mounting the punches and limiting the punching stroke, together with means for stripping the punches from the work. A ring of pivoted punches 1 is connected detachably by bolts 24 to a loose sliding member 11 controlled by springs 10. A ram 5 descends until the ring of punches is lowered into the die block 3, a centring ring 26 co-operating with the conical upper part 20 of the die block during this process to secure exact positioning of the punches. When the centring ring engages the part 20, the punches are fixed against further descent, but the ram descends still further by compressing the springs 10. This further movement causes the conical mandrel 4 to force the punches radially outwards through the cage blank 2 and into slots in the surrounding die block 3. On the return movement the ram and mandrel relieve the pressure on the springs before the punches are moved upwardly, and stripper plates 35 move the punches inwards to release them from the blank during this period. Further upward movement then raises the punches clear of the dies. The punching stroke is limited by stops 31 on the punches striking against the ring 20. At the end of the upward movement a bar 43, connected to the ram, contacts with the member 39 and raises the lower die 3 out of the holder to enable the blank to be stripped therefrom. The spring 41 restores the die to its seating when the pressure of the bar 43 is removed. Fig. 7 shows a perforated cage undergoing a second operation in the press, to bevel off the corners of the bridges between the slots. A sliding spring pin 56 engages one of the slots to position the cage, the pin being forced rearwardly by one of the shaping punches 51 during its acting stroke.
