Title: Method of and apparatus for hulling peas or other crops
IPC: A23N15/10
Filed: 1963-02-20
Abstract: 961,808. Separating apparatus. FMC CORPORATION. Feb. 20, 1963, No. 6809/63. Heading B2H. Apparatus for separating pea crops from vines and hull particles comprises a sieve made of nylon string netting 65, the elastic characteristics of the strings being such as to enable the sieve to flex and stretch in use so as to prevent clogging. As shown, each of the spaces formed between longitudinal and transverse frame members of a drum 22 is provided with a netting consisting of intersecting and preferably connected nylon strings which are tensioned between and stapled to the framework. Vines bearing the crop are tumbled by members 30 on to beaters 35 which break open the hulls to release the crop, the beaters being rotatable with the drum which is supported by end bearings and rollers 23. The vines and large particles of hull are retained in the drum by the netting while the crop and small particles of hull discharge through the netting on to a pair of inclined separating conveyers 41, 42 which allow the crop to roll downwardly into a collector 50 and carry the particles of hull upwardly.

A maximum demand alarm circuit comprises contacts ALC1, ALC2 driven at an angular speed dependent on power consumption and other contacts 1, 2 driven at a fixed angular speed by a clockwork or synchronous motor. When the power consumption rises, contacts ALC1, 1 are closed first to energize a relay 8 which illuminates a lamp 18 and extinguishes a lamp 17 and later another lamp 22 is illuminated through a relay 7. Contacts 7B shunt contacts 2 and contacts 7C may disconnect non-essential loads in a selected sequence if desired, or start a diesel or turbo generator. Breaking of contacts ALC2, 2 has no effect due to contacts 7B until contacts ALC1, 1 are broken due to reduction of load. Relays 7, 8 should be of the make before break type to prevent fluttering or an additional relay (9) (Fig. 3, not shown) may be employed. An additional optical signal can be operated when contact 2 opens. The contacts may be driven by means of counting time spaced and power rate pulses. The optical signals may be supplemented or replaced by audible signals.

[Also in Group XL(c)] In a television receiver for use with the N.T.S.C. type of signal (i.e. a signal including a chrominance subcarrier bearing modulations in quadrature phase relationship and a subcarrier synchronizing "burst" of reference phase which occurs during the back porch interval), the signal from the quadrature-phase subcarrier detector (a homodyne detector) is gated during the back porch interval, i.e. during the colour synchronizing "burst", integrated and applied via a reactance valve to control the local homodyne oscillator to minimize the detector output, thereby to maintain the homodyne oscillation in phase quadrature relationship with the "burst". An output may also be derived in a similar manner from the in-phase detector, this output being at a maximum when the homodyne oscillation and "burst" are in the correct phase relationship, and employed for automatic gain control or to switch off the colour portion of the receiver in the event of failure of the chrominance signal.

Abstract: 1381674 Fluid pressure servosystems BENDIX CORP 21 Feb 1972 [24 March 1971]  7916/72 Heading G3P A moment-balance control mechanism regulating, e.g. the speed of an I.C. engine, includes a governor 68 which applies a force to a lever 54 subjected to an adjustable bias from temperaturecompensated spring 94 via lever 98, roller 104 on lever 110 and rollers 80 on a lever 84 having a further, grooved roller 86 engaging track 90. Lever 54 controls leak-off from the full-area side of differential piston 26 which positions lever 84 to maintain a balance at lever 54, the position of the piston being a linear function of engine speed when x = 1 1 . In a modification, a further lever (126) is interposed between lever 98 and roller 104 and the spring force is applied to this further lever through a roller shiftable longitudinally in response to an engine operating temperature or pressure. The mechanism of Fig. 1, might alternatively function as a flowmeter if the governor is replaced by a bellows responsive to the pressure drop across a restrictor. In a further modification, lever 54 receives the force of spring 148 via lever 146 and a roller 144 adjusted by piston 26 which in this case assumes a position which is a function of the square of a signal applied to lever 142 which shifts lever 84 longitudinally. In this case, piston 26 and parts 144-152 may be replaced by a member which responds to the pressure in line 46 and applies a feedback force to lever 54.
