Title: Improvements in or relating to an apparatus for drying crop
IPC: F26B9/06
Filed: 1962-06-06
Abstract: 1,008,960. Drying grain. C. VAN DER LELY N.V. June 6, 1962 [June 28, 1961], No 21919/ 62 Heading F4G. Batches of crop, e.g. grain are dried in a hopper 1 by the upward passage therethrough of heated air from a main fan 9, a burner 12 and an auxiliary fan 13 to a distributing case 4 from which it passes through apertured ducts 6 in the base of the hopper. The period of hot air flow is predetermined by a timer (not shown) in the circuit of the auxiliary fan and burner arrangement 7 and thermostats (not shown) in the hopper and distributing case 4 maintain the air temperature within predetermined limits during the period of hot air flow. After termination of the hot air flow the main fan continues to pass unheated air through the grain for cooling purposes until a further timer in the circuit of the main fan cuts the supply of current thereto.

IPC: F02B25/00
Filed: 1921-08-19
Abstract: 168,066. Whitcombe, C. H. Aug. 23, 1920, [Convention date]. Two-stroke-cycle engines; driving-gear. - An engine having one or more pairs of coaxial cylinders and one or more charging pumps driven at a speed which is a multiple of the speed of rotation of the crank shaft has its pumps mounted on the top of the crank chamber. I n the engine shown in Fig. 1, a pair of coaxial cylinders 6, 6<A> is charged with combustible mixture by a reciprocating piston pump 8 driven at twice the speed of the crank shaft 1 to which the crank shaft 10 of the pump is connected by chain or other gearing. The pump delivers alternately through pipe 13 into the working cylinders the ports in which are controlled by the pistons. Alternatively, the inlet ports 8<c> may be disposed in the heads of the cylinders. The main pistons are connected to the crank shaft by rods inclined to a plane containing the axes of the pump and working cylinders. A lubricating pump is mounted in the sump of the crank chamber. A single pump may charge four cylinders, and in a six-cylinder engine two pumps may be used.

Title: Improvements in or relating to voltage stabilizing circuits including transistors
IPC: G05F3/22
Filed: 1956-07-18
Abstract: 806,537. Automatic voltage-control systems. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 18, 1956 [Aug. 4, 1955], No. 22255/56. Class 38 (4). [Also in Group XXXVI] In a circuit for stabilizing the voltage across terminals 4, 5, Fig. 1, the collector of transistor 6 is connected to the junction 4 of resistors 2 and 3, the base is earthed, and the emitter is connected to the base of a further transistor 10, the emitter of which is earthed and the collector also connected to terminal 4. The transistor 6 has a low punch-through voltage, e.g. 15 volts, obtained by making the base region only a few microns thick, the punch-through voltage being the value at which the space charge region at the collector extends through to the emitter, thus reducing emitter-collector impedance to a low value. The transistor thus has a constant voltage characteristic similar to that of a neonfilled discharge tube. The punch-through voltage of transistor 10 is of a much higher value and this transistor amplifies the variation of current through transistor 6. In a modification a further transistor connected between transistors 8 and 10 acts as an impedance matching device. In a further modification, a second transistor 18, Fig. 4, having a low punch-through voltage, is connected as shown and thus results in adding the punch-through voltages of transistors 6 and 18. Fig. 5 shows an arrangement in which a high punch-through voltage transistor 23 is connected between the negative terminal of the input source and the output terminal 4, and the base of a low punch-through voltage transistor 32 is connected to the tap 35 on a potentiometer 36 across the output terminals. When the voltage between terminal 4 and tap 35 exceeds the punch-through voltage of transistor 32, transistor 27 is unblocked and the resulting potential drop across resistor 22 decreases the current through transistor 23. In this way the voltage between terminal 4 and tap 35 is restored to the value of the punch-through voltage of transistor 32 and current ceases to flow through resistor 22. The voltage at terminals 4, 5 is thus stabilized in accordance with the position of the tap 35.

The combs may be made of wire supported on a bar Q, or of sheet metal cut so as to form teeth, each having a longitudinal ridge, and are loosely pivoted in the frames in a balanced manner, with or without counterweights R, so as to have a rocking movement the extent of which is limited by stops S, T. The inclination of the screen frames is independently adjustable. In the arrangement shown, the middle screen is pivoted to the support F at K and secured in the required position by the pin-and-slot device L, and the upper and lower screens are pivoted at M, M' to a bar V attached to the middle screen and are adjusted by the slotted plates N, N<1>. The apparatus may be combined with the machine described in Specification 181,941 so as to receive its reciprocating movement therefrom and deliver the small tea and stalks thereto by way of the hoppers G, H. The large tea passing over the screens is discharged by the shoot O, P.

The rotary member may comprise a shaft 4 carrying cams 6, which tilt mercury switches 12 each supported in a cradle 8 pivoted at 9 and furnished with a finger 7 resting on the cam periphery. Spring leads 15, 18 support part of the weight of the mercury switches. The clockwork 22 comprises a spindle 23 coupled to the shaft 4 by a sleeve 5, and driven by a spring 26 on a shaft 28 from which extends an arm 40 pivoted at its outer end to a rod 42 forming a continuation of the core 43 of a solenoid 44. Vanes 31, 31<1> control the speed of the clockwork. The top of the core 43 is attached by a member 46 to a mercury switch 48 pivoted at 49. When the core rises under the lifting action of the arm 40 rotated by the shaft 28, the switch 48 is tilted and the solenoid circuit made, thus drawing down the core 43, re-tensioning the spring 26, and tilting the switch 48 to break the current till the core again rises to its topmost position. The cam-shaft 4 may be replaced by a contact drum on the conductors of which bear fingers connected to the several lamps &c.
