Filed: 1962-10-23
Abstract: 1,007,471. Machine tool details. NATIONAL ACME CO. Oct. 23, 1962 [July 6, 1962], No. 40133/62. Headings B3B and B3T. [Also in Division F2] A multi-spindle automatic lathe has a collet chuck 29 threaded on one end of a rotatable and reciprocatable spindle 24 and is opened and closed by an axially slidable sleeve 30 having grooves 35, accommodating balls 42. Balls 42 react against grooves 38 in a stationary sleeve 37 and are projected inwardly to shift the sleeve 30 to the right by a tapered surface 44 of a sleeve 43 which is fast axially with a piston 47. The piston is shifted to the left or to the right by the admission of air through ports 52 or 51 to open or close the chuck. The spindle 24 is rotatable under the control of a clutchbrake arrangement, and is reciprocated by means of a cam 86 acting through an arm 79 and a link 80 on a casing 21 fast axially with the spindle 24. In operation, assume that a tool 95 moves transversely towards the stock 96 carried by a machine spindle 97 and starts to separate the finished workpiece 77 from the remaining bar. Either before cut-off starts, or after it is 25% completed, cam 86 shifts the chuck towards spindle 97, the spindle 24 being rotated through its engaged clutch 126, 127, and the chuck being maintained open by air admitted through port 52 from a source 93 under the control of a solenoid valve 89. The chuck thus slides over the workpiece 77 until rightwards movement is limited by a stop nut 68. At this point a cam-operated switch 90 causes actuation of the valve 89 so that air is introduced through port 51 to close the chuck to hold the workpiece until it is completely cut-off. When the workpiece 77 is completely severed, the chuck is moved to the left, and the spindle 24 stationed by a cam-operated switch 155 which actuates a solenoid valve 154 which is shifted to admit air through a port 140 to a servomotor 136 which disengages the clutch 126, 127 and applies the brake 130, 131. A back finishing tool, such as a rotating milling cutter 157 can now operate on the workpiece upon the subsequent rightwards movement of the still closed chuck. This movement to the right is limited by the engagement of a stop 84 with a tool slide 18. The chuck then moves completely to the left at which time the camoperated switch 90 operates to open the chuck. The completed workpiece is thus released and can be ejected from the front of the collet chuck 29 by an ejection mechanism or ejected rearwardly through the hollow drive spindle 24 by the pushing action of successive workpieces.

Abstract: 1,168,107. Thermistors. HITACHI Ltd. 4 Sept., 1967 [14 Sept., 1966], No. 40359/67. Heading H1K. A thermistor is made by heating a mixture of oxides including V 2 O 5  in a reducing atmosphere to produce a mixture including V 2 O x , where x<5 and preferably x#4, adding to this mixture a second oxide material which may or may not include V 2 O 5  or V 2 0y, where x<y<5, and sintering the resulting mixture. The final material essentially comprises microcrystals of V 2 O 4  in a glassy oxide matrix. The thermistor, which may be provided with leads of Pt or Pd, has a resistivity which decreases sharply with increasing temperature over a narrow temperature range. The preferred method of manufacture entails firing, melting and re-cooling a starting mixture of V 2 O 5 , SrCO 3  and (NH 4 ) 2 HPO 4  to form a glassy body containing V 2 O 5 , SrO and P 2 O 5 , and pulverizing this body. A portion of the powder is heated in NH 3 , alcohol, benzene or hydrogen to reduce the V 2 O 5 , and portions of the reduced and unreduced powders are mixed together with water to form a paste which is applied to a pair of leads and dried and shaped. The device is then sintered at 900-1300‹ C. in N 2 , and rapidly cooled. The two powders which are combined to form the paste may, in fact, both be reduced, but to differing degrees. The oxides included with V 2 O 5  in the starting material and the second oxide material are selected from those of P, Sr, Ba, Pb, Ag, Li, Na, K, Be, Mg, Ca, La, Ce, Zr, Zn, Cd, B, Al, Si, Sn, Bi, U, Y, Ge, Fe, Co, Ni, Mn, Ti, Nb, W, Mo, Ta or Cr.

[Also in Divisions H2 and H3] The dissipation or voltage across a mechanical or electronic switch is reduced during turn off by a plurality of circuits each comprising a capacitor shunted by a diode in series with a resistor or during turn on by circuits comprising an inductor shunted by a diode and resistor, or one of each circuits is provided. The figure shows an inductive load Z periodically connected to a D.C. supply Ub, Zb by a transistor, current being maintained in the load during the off periods by a free-wheeling diode connected across Z. A capacitor is connected in series with a diode across the transistor (or across the load, Fig. 8, not shown) to slow the intial rate of rise of voltage across the transistor when it is being switched off, so as to reduce the collector dissipation. During switching on the diode is reversely biased so that the capacitor discharges more slowly through the resistor and mainly when the collector voltage is low. A plurality of such circuits having different time constants may be used (Figs. 11-13, not shown). The circuits also reduce the rise of transistor voltage during switching caused by ringing of the supply inductance. Reduction of dissipation during switching on may be effected by additional inductance Z 2  or Z 2 <SP>1</SP> in series with the supply. This causes ringing, during switching on, in a sense to rapidly reduce the voltage across the transistor. Ringing during switching off is prevented by a shunt dumping resistor R 2  or R 2 <SP>1</SP> connected in series with a diode. The transistor could be replaced by a corresponding electron tube or by a controlled rectifier. The invention may also be used for a mechanically or magnetically operated relay, for vibrating contacts or for a mercury jet interrupter.
