Patent EP-0003876-A1 (EP)
Inventor: GANE BRIAN RICHARD
IPC: C07C31/08
Filed: 1979-02-05
Abstract: Ethanol is produced by reacting methanol with carbon monoxide and hydrogen at temperatures in the range 150 to 250°C and pressures greater than 100 bar in the presence of a cobalt catalyst and an additive which is miscible with methanol containing up to 20%w/w water, which additive is an alcohol, an aldehyde, a ketone or an ether. Particular additives are n-propanol, n-butanol, acetone, acetaldehyde, 1,4 dioxane, tetrahydrofuran, di-n-propylether and diphenyl ether. Optionally the catalyst is promoted with iodine or bromine or preferably both iodine or bromine and an organo-phosphorus compound. Other additives such as non-polar solvents, acids and derivatives thereof and inert liquids can be incorporated in the reaction mixture.

Abstract: A regulated DC power supply circuit comprises first and second transformers (T1 and T2), a transistor (Q) and trigger means to periodically cause the transistor to conduct to supply DC current to the transformers. On application of such current, flux builds up in the core of the second transformer (T2) and a winding (P2) of the second transformer (T2) maintains conduction of the transistor (Q) until the core saturates, whereupon the flux reverses and drops in value, the transistor is switched off and collapse of the field in the first transformer dumps electrical energy into a rectifier circuit (58, 60) connected to the first transformer (T1) to produce a DC output voltage. A Zener diode (66) or the like connects the DC output voltage to a winding (P3) of the second transformer (T2) to control the value to which the flux in the core of the transformer drops to after saturation, thereby to control the time taken for saturation when the transistor (0) next conducts, and therefore the amount of energy dumped into the rectifier circuit (58,60), in a sense to stabilize the DC output voltage at a desired value.

Abstract: A feeder (25) for livestock and the like is disclosed. The feeder has a feed receiver body (31) for receiving and storing a flow of feed from a conveyor. As shown in FIGS. 2,3 and 4, a drop tube means (51) extends from the feed conveyor into the feed receiver body (31), and includes at least one wall (65) mounted for vertical motion relative to a fixed wall (55,57). When the movable wall is in a raised position, that movable wall (65) and the fixed wall (55,57) define a verti- cally oriented opening (64) through which feed can pass from the drop tube (51) into the receiver body (31). By adjusting the position of the movable wall (65), the amount of feed collected in the receiver (25) can be correspondingly changed. When a stopper valve member (40) is drawn away from a discharge opening (44), the feed pile collected in the receiver body (31) is discharged from the receiver (25) for livestock consumption. A stopper actuator (47) includes a flexible member (49) connected to the stopper valve (40), and a rotatable wind-up device (48) connected to the flexible member (49). When the wind-up device (48) is rotated, the flexible member (49) is wound up and draws the stopper valve (40) away from the discharge opening (44).

Title: AC electric motor driving circuit having overload protection circuitry
Inventor: KAWADA SHIGEKI
IPC: H02M7/48
Filed: 1979-11-02
Abstract: Overcurrent protection circuitry for an electric motor driving circuit (3) has an overcurrent detector (r,, r 2 , r 3 , 10) monitoring current (for example i 1 ) flowing to the motor (4). The circuitry is such that when an overcurrent is detected current delivery from the driving circuit (3) is interrupted (for example through the operation of comparator 10a, resetting flip-flops 93a, 93b, and through AND gates 94a, 94bto turn off current delivery transistors Q, and Q 2 ). The circuitry then operates so that current delivery is restored after the interruption (for example by pulses from pulse generator 96 acting to set flip-flops 93a and 93b). Upon such a restoration if detector (10) still detects an overcurrent current delivery is again interrupted (by resetting flip-flops 93a, 93b). 
     The result is that the drive circuit (3) is allowed to supply current intermittently but not above a value preset in the overcurrent detector even when the motor is overloaded, thereby allowing the motor to run continuously without observable halt in operation.

Abstract: In this all-sheet boiler, the firing chamber (1) is followed by large double-walled afterheating surfaces (4) in the shape of a spiral, which achieve high efficiency and have features which promote good flow. The heating surface can be infinitely increased or reduced by means of a deflecting device (25) in order to adapt to the respective off-gas temperature and the required heating capacity. This is achieved by measuring, or sensing the off-gas temperature by means of a bimetallic element or thermostat. With a low load requirement, the heating surface can be reduced in a particularly adaptable way by the bypass (31) with the deflecting flap (32) in the pivotably mounted terminating plate (19), in order to avoid clogging of the heating boiler and of the chimney. In order that cleaning of the spiral can be carried out easily, in the pivotably mounted terminating plate (19) there is a closable cleaning opening (21), through which the cleaning appliance can be introduced into the hot, sealed spiral heating section. Easy, frequent cleaning allows the high efficiency to be maintained by preventing rust from forming. <IMAGE>
