Title: Wire saw
Inventor: MATSUKURA YASUMASA
IPC: B23D57/00
Filed: 1989-12-08
Abstract: A wire saw has a wire (B) wound around a plurality of multigrooved rollers (7, 8) with turns in rows to thereby cut a work (A) by means of the wire portion (B3) running between said rollers. By reversible revolution of the multigrooved rollers (7, 8) the wire (B) is moved gradually from a wire feeding side to a wire recovery side, while being given a reciprocating motion between the multigrooved rollers (7, 8). In addition, the multigrooved rollers (7, 8) are rotated around a fixed axis to swing the operative portion of the wire (B3) between said rollers (7, 8) through a circular arc in a manner to produce a contact surface approximating to a point between the work (A) and the wire (B) whereby a larger concentrated load is applied to the contact point utilizing fully permissible additional tension of the wire (B), thus accelerating cutting process speed and raising cutting process accuracy. Drive means for the wire (B) include movable pulley type double-speed mechanisms (51, 54) and an endless drive element (57) which follows the same path as and moves synchronously with the wire. <IMAGE>

Patent GB-903444-A (GB)
Abstract: 903,444. Electric analogue calculating; power measurements. LANDIS & GYR A.G. May 11, 1960 [May 13, 1959], No. 16643/60. Class 37. In a circuit wherein a semi-conductor of, e.g. germanium, silicon, or indium arsenide is subjected to a magnetic field to develop a resistance proportional thereto which is traversed by a current developing a voltage drop proportional to the product of the field and the current magnitudes, it is shown that the resistance R Bt  for field B at temperature t is given by where R oo  is resistance for B=0, t = 0; a is a constant; and that if the current it is given by where i o  is the current for t=0, the developed voltage drop representing the product remains constant with temperature change (Fig. 1, not shown), so that connection in series with the semi-conductor of a resistance of comparatively high valve and similar temperature coefficient compensates for the temperature variation of the semi-conductor. In Fig. 2 a semi-conductive disc R B  is energized with a voltage e from transformer 6 energized across mains 8 in series with a resistance W of value greatly exceeding that of R B  under operating conditions; and the disc is subjected to a magnetic field B from coil 9 energized in series with mains 8. Resistance W has a temperature characteristic similar to that of R B , given by where W t , W o  are resistance values at temperatures t and 0 so that the current i is given approximately by and the voltage drop across R b  measured by instrument 10 is proportional to the alternating current power in mains 8. Resistance W may be of the same material as resistance R b  or may be composed of a suitable network of positive and negative temperature coefficient resistors.

Patent GB-2249560-A (GB)
Title: Driving device for sewing machine
Inventor: MORI SHUSHIN
IPC: D05B69/18
Filed: 1991-11-05
Abstract: In a sewing machine, a judgment is made whether the speed N of the motor driving the needle is above or below a threshold speed Bs. Normally the needle speed is above the threshold and a constant power is supplied at a level Ps set by a pedal. When the needle speed drops below the threshold, e.g. on sewing a thick workpiece, the power is alternated between power on and power off states to drive the needle in a manner similar to a hammer driving a nail. The indication of needle speed may be obtained by measuring the rotating speed of the motor, judging the load applied to the motor, or by detecting the driving current supplied to the motor. The motor is intermittently operated by an oscillator 57 which controls a LED 51 in a photocoupling connection of the motor drive system, the diode being normally actuated by a pulse-width modulating circuit 35. The oscillator 57 may be replaced by timers. Instead of controlling the motor a clutch may be engaged intermittently. Instead of the automatic control system shown the intermittent drive may be selected manually. <IMAGE>
