Title: Control system for reciprocating machine tool slide
IPC: B23F5/02
Filed: 1972-12-19
Abstract: 1391557 Grinding machines R D FERRERA 19 Dec 1972 [24 May 1972] 58564/72 Heading B3D [Also in Divisions G3 and H3] The slide 38 of a grinding machine is reciprocated at high frequency and positioned by hydraulic actuator 34 supplied from pump 10 through a proportional electromagnetically operated valve 20. The slide movement is detected by position transducer TP and velocity transducer TV and the resulting signals are compared with signals representing desired position and velocity supplied from generator 56. In the comparator stages 52, Fig. 2 (not shown), the position signals are initially compared and the error signal added to the velocity signals to provide a control signal for electromagnet 21. The signal generator 56, Fig. 3 (not shown), includes an oscillator consisting of two integrating stages separated by an inversion stage which includes a Zener diode to limit its output. The overall feedback signal can be varied to alter the oscillator frequency and a D.C. signal representing mean position is added to provide the positional signal on line 58. The signal on line 60 is taken from the limited stage output and thus represents velocity.

Title: Locking apparatus
IPC: F16F15/30
Filed: 1978-10-19
Abstract: A device responsive to changes of temperature, for clamping a member at a point on its path, which device may be embodied in a rotor balancing equipment consisting of a track 14 which in use is secured to a rotor 12 to be balanced and in which balancing weights 22 can move. The track is made wholly or in part of a heat- recoverable material preformed in cross-sectional shape such that at a normal operating temperature of the shaft the weights are locked in the track (20) but at a significantly different temperature the weights are free to move along the track (20A). The rotor with the track attached is rotated, the weights are released by change of temperature and take up balancing positions, and the temperature is then returned to lock the weights in those positions. A preferred heat-recoverable material is a copper-zinc-aluminium alloy, which may have a transition temperature range -80 DEG C to -40 DEG C. <IMAGE>

Title: Waveform shaping circuits
IPC: H03K5/003
Filed: 1979-03-07
Abstract: The arrangement comprising switching device (Field effect transistor) 32, (optional) resistor 46 and comparator 34 in Fig. 3 is functionally equivalent to an ideal diode, which may be used in circuits for accurately limiting Fig 3 or clamping Fig 4 an input waveform to a selected or predetermined level on its output. Current flow through the field effect transistor (FET) 32, 52 is controlled by the voltage difference between the output voltage and the predetermined level. If the output voltage exceeds the predetermined level, the comparator 34, 54 provides a control voltage to the FET gate to turn it ON. When the FET is ON, the output waveform is clipped or clamped to the predetermined level. When the FET is OFF, the circuit provides an output waveform having characteristics which depend upon the selection of various impedances such as 30 Fig. 3; 48, 50 Fig. 4. <IMAGE>

IPC: G01D11/26
Filed: 1979-07-30
Abstract: For use with a lighted display which must be seen while energized in a high brightness environment, an arrangement which prevents extraneous light from entering the display for precluding ambiguity to viewer as to whether or not the display is energized. The arrangement comprises a light transmitting means e.g. a light pipe (20) including a viewing surface (32) having a matte finish and a highly polished surface (34) opposite the viewing surface (32). The matte finish of the latter is effective for diffusing extraneous light and minimizing such light entering the display and the highly polished surface (34) is effective for efficiently transmitting light from a light emitting means (26). <IMAGE>

Filed: 1980-02-22
Abstract: A mounting for a helicopter pylon has resilient vertical support links (24-27) between the pylon (12) and the helicopter fuselage (13). The links have a composite spring rate which establishes a resilient support for the fuselage at the at thrust required to support said fuselage in normal flight and in which oscillatory vertical force transmitted to fuselage is minimal for acceptable static deflections of the pylon. Stops limit deflection between pylon and fuselage. Links (24, 25 etc.) are mounted at the ends of a pair of rigid beams (20, 21 and 22, 23) secured at their centres to the transmission portion of the pylon (12). A vertical pin (24b) extends downward at the end of each beam into a respective hollow receptacle (24a) secured to the fuselage and having a reentrant bore (Fig. 5, not shown) providing a down facing shoulder. A resilient body (24g) couples each pin to its receptacle. An enlarged foot on each pin operates between the fuselage and shoulder to limit deflection of pylon and the resilient coupling. There may be anti-torque links (32, 33). The pylon may include two engines (Figs. 8-10, not shown). <IMAGE>
