Abstract: Saturated triglycerides are reacted with glycerol in the presence of either a glycerolysis catalyst or a pre-formed glycerate to provide a product which is a mixture of monoglycerides, triglycerides, 1, 2-diglycerides and 1,3- diglycerides. The mixture is stored in the presence of a low temperature rearrangement catalyst at a storage temperature below the melting point of the gylceride ester components of the mixture and substantially all of the mixture is converted into 1,3-diglycerides. In this way there are prepared, for example, 1-palmitoyl, 3-stearoyl diglyceride, 1,3-distearoyl diglyceride and 1,3-dipalmitoyl diglyceride, which are appropriate precursors for the synthesis of confectioner's hard butters, and the like.

Abstract: A viscous fan clutch is typically employed in a fan drive mechanism within a truck or automobile. A shaft (12), driven by the engine, rotates a clutch member (24) within the fan drive. The clutch member is arranged for fluid engagement with a body member (38) for the transmission of torque thereto when fluid is disposed in an operating chamber defined by complimentary shear surfaces (30,64) in the clutch and body members. During relative rotation between the two members, fluid is pumped through a return passage (76,78) to a valve (97) coaxially disposed with the driven shaft which selectively directs a flow of viscous fluid alternately to a storage chamber (73) or directly back into the operating chamber. The. valve is biased into a first position in which the fluid is directed into the fluid storage chamber and is actuated into the second position by means of a coaxially disposed solenoid (120) acting upon ferrous metal members of the valve. When the valve is in the second position, a port is opened for fluid communication between the fluid storage chamber and the operating chamber.

Abstract: The reflector of an acoustic echo ranging system is matched so as to make up for the influence of the temperature at the bottom of the reflector, on the measurement of the back-reflected signal. The acoustic signal receiver being stationary the transmission frequency is controlled by a temperature responsive electronic circuit so that the receiver is always located at the same pressure antinode. Alternatively, the transmission frequency being fixed, the position of the receiver is controlled by a temperature responsive mechanical gear causing the position of the receiver to coincide with the same pressure antinode.

Abstract: A constant loop gain is achieved in a flyback type DC to DC converter (102) by use of feedback to correct for load variations and feed forward to correct for line voltage variations. The feedback signal (103) and a reference voltage (Vr) are compared by an error amplifier (104). An output of the error amplifier is multiplied by a constant (112) and is added to a signal (107) proportional to line voltage. The resulting sum (113) causes modification of the slope of a ramp voltage (Vc) which is compared (105) to the voltage at the output of the error amplifier (104) to control the «on times of the converter switching devices.
