Abstract: A shiftable transmission drive with assured input-­output relationship includes a drive motor-transmission mechanism wherein a drive motor (10 or 110) drives an output shaft and load (32 or 132) at different rates through a shiftable transmission (18 or 118). The output shaft and load is always directly coupled to the drive motor through the shiftable transmission. The output shaft is thus always under control and its position precisely known. An encoder (36 or 136) is coupled to the drive motor, and thus to the load, for indicating both incremental motion at the load and position at which the transmission may be shifted. The transmission is preferably a spur gear transmission.

Abstract: A variable volume apparatus for an internal combustion engine includes a cylinder (22) and a piston (40) sliding in the cylinder bore (24) and having a sphere shape (60) cut by two parallel planes (102, 104) on either side of its major horizontal diameter. The upper side (58) of this twice truncated sphere is solid and its underside is hollow. A short threaded stem (70) is mounted in the center of the piston (40) for rigid attachment to the connecting rod (42). The spherically contoured sidewalls of the piston (40) are thin and the contour (87) of the inner walls match the contour (60) of the outer walls. These thin side walls expand slightly and can distort slightly to maintain a tight seal between the piston (40) and the cylinder (22). A bevelled lip (62) rings the bottom of the spherical side walls and angles in towards the center of the piston (40) to provide lubricating and cooling for the piston side wall of the piston.

Abstract: A method of preventing smoke curling from beneath depending enclosure walls of a grease extraction ventilator, (V) comprises providing a series of apertures (10, 11) in the walls (12-15) from adjacent the lower edge thereof for a predetermined distance upwardly. The apertures are preferably comparatively small and relatively closely spaced, being preferably placed in parellel rows, also parallel to the lower edge of the wall, with the apertures of adjacent rows. The number of rows may be varied, depending on the height of the wall and the capacity of the ventilator, with additional apertures for a ventilator having a larger capacity. The apertures may be slots, such as relatively short, and with the spacing between parallel rows being equal to or less than the height of the slots, with the lowest row being relatively close to the lower edge of the wall. Or, the apertures may be circular or having other shapes, such a oval, elliptical or the like. A device for preventing smoke rollout consists in apertures in the depending walls of an enclosure into which pass heated products of cooking, positioned as described in connection with the method.

Abstract: @ An injection-locked waveguide oscillator comprises a first diode (3) having a free-running fundamental frequency above the local cut-off frequency of the waveguide (1) and a second diode (4) having a fundamental frequency below and a higher harmonic above the local cut-off frequency. The first diode (3) may be an IMPATT diode and the second diode (4) a Gunn diode. The free-running fundamental frequency of the first diode (3) is close to the higher harmonic of the second diode (4) so that the second diode (4) injection-locks the first (3). Locking in the reverse sense is inhibited by the inherent loss in conversion from the higher harmonic to the fundamental in the second diode (4), thus avoiding the need for a circulator or isolator. The two diodes (3, 4) suitably are mounted in a common waveguide (1) for a simple, compact structure.

Abstract: With the invention the surface chemistry on objects plated in an electroless plating bath, the rate of the plating and the contaminant level in the bath are main­tained and optionally controlled. 
     For maintaining and controlling the surface chemistry cyclic voltammetry measurements (31) are made for different p H  conditions (29, 30) of the bath. Pourbaix diagrams are determined from these measurements which indicate the transition between metal species being plated by the bath. The open circuit potential (32) of the bath is monitored by a potentiostat and compared with a set­point open circuit potential (33) which represents a desired metal species on the pourbaix diagram. The monitored open circuit potential and the setpoint are utilized to derive an error voltage (34). The error voltage will control the concentration of a chemical constituent of the plating bath to maintain the desired method species on the plating surface. 
     The plating rate and the contaminant level are prefer­ably monitored by measuring the complex impedance (35) be­tween a reference electrode and a working electrode immersed in the bath. From the real portion (36) of the measured impedance the plating rate and from its imaginary portion (38) the contaminant level are determined. An error signal (37) is produced from the difference between the plating rate derived from the real portion of the   impedance and the setpoint plating rate. Controlled by this error signal (40) another constituent of the plating bath is added in order to keep the plating rate constant.

Abstract: An epicyclic mixing system for materials held in a tank is provided having dual concentric sun shafts (12, 18) which both orbit a pair of planetary drive (56/20) shafts having mixing implements (58, 24) at their bottom ends and act to rotate the pair of planetary drive shafts (56/20) about their own axes (14). The two concentric shafts (12, 18) are connected to dual drivers (11, 11a) through separate drive systems (98/100) so that the shafts (56/20) can be selectively operated at different rotating speeds. 
     The epicyclic mixing system (194) include upper and lower housings driven about a central axis that extends through the upper housing by a sun drive shaft. The lower housing is adjustably secured to the upper housing. A first planetary drive shaft extends through the upper housing and a second planetary drive shaft extends through the lower housing. The first drive shaft is driven by a fixed sun gear about which the lower housing rotates so as to rotate the first drive shaft, which rotates the second drive shaft by way of a gear train. The housings may be adjusted so that the sweep of the mixing implements at the bottom of the planetary shafts may fit tanks of various diameters.
