Filed: 1938-05-17
Abstract: 514,848. Fat and oil compositions. STEVENS, A. H. (Ross & Rowe, Inc.). May 17, 1938, No. 14679. Drawings to Specification. [Class 91] [Also in Group IV] A fat-soluble product is obtained by treating fatty acids with a condensing agent such as phosphorus pentoxide or aluminium chloride and continuing the reaction to obtain products of enlarged molecular structure up to the point where degradation occurs with deposition of carbon. The fatty acids may be replaced by glycerides such as animal and vegetable oils, fats or waxes. The products may be. purified by extracting any glycerol present with acetone. The reaction may be carried out at the temperature of boiling water. In an example, 100 gms. of lanoline are dissolved in 100 cc. of benzene and treated with 10 gms. of phosphorus pentoxide, heated for 2 hours in a steam bath and left standing over night. The material is then filtered and the filtered material extracted with acetone. The product is suitable for modifying the viscosity of a chocolate mixture. Other examples describe the treatment of cerotic acid from carnauba wax, palm oil and beeswax.

Title: Improvements in selector switches for automatic telephone systems
IPC: H04Q3/42
Filed: 1928-05-22
Abstract: 291,352. Telefonaktiebolaget L. M. Ericsson. May 30, 1927, [Convention date]. Automatic exchange systems.-In a reverting- impulse system in which the locking-bar SS of a selector is displaced with reference to the reverting-impulse bar IS, the open-circuiting of the locking-magnet SM is prepared by the impulse which brings the register IK1 to its marked posi tion and is completed by the next impulse, the selector then continuing to move the whole length of a tooth until the catch SH drops into the next notch. High selector speeds are made possible by this arrangement. The reverting-impulse circuit is of the type in which each closing and each opening of the circuit counts as a separate impulse. The registers RK1, RK2 having been set, contacts SO1, SO2 SO3 are closed to complete circuits for the selector locking and clutch magnets SM, KM and the register magnet IM1, this last being controlled through a relay IR by the bar IS so that the register IK1 takes a step at each closing and each opening of circuit 14. When the register IK1 reaches a position corresponding to the joint settings of RK1, RK2, relay SR1 is energized over circuit 15 (or SR2 over 17), locks itself, and opens one point in the circuit 11 of SM, but this circuit remains closed over a back contact of SR2 (or SRI). At the next impulse, relay IR is deenergized (or energized) and energizes SR2 (or SR1) to complete the opening of circuit 11, this happening before the register IK1 has time to take a step. The magnet SM is de-energized at a moment when the catch SH has just passed a notch and the selector rides on into the next notch.

Abstract: 1,023,961. Electro - analogue calculating. TEKTRONIX Inc. April 17, 1963 [May 7, 1962], No. 15154/63. Heading G4G. [Also in Division H3] A sampling oscilloscope circuit (see Division H3) comprises a Miller-type integrator acting as an analogue memory and which receives input pulses corresponding in sign and magnitude to the difference in amplitude between input signals and the output from the integrator and charges or discharges the Miller capacitor accordingly. The difference pulses are applied at 84 to a gate comprising the diodes of 70 and 72 which, when a gating pulse is applied to transistor 90 pass the input pulse to the grid of valve 20. This valve together with transistors 34 and 44 and Miller capacitor 58 forms a memory circuit and the charge in capacitor 58 is reset by the gated pulse to a new value which is retained until the next gating pulse appears. Diodes 118 and 120 biased through a circuit 74, 76, 78, 80 prevent the input signals from exceeding a certain value while the output amplitude is prevented from exceeding desired positive and negative values by a limiter circuit 62, 64 and by applying only a small potential to the collector of transistor 44. A further diode 60 ensures that the Miller capacitor 58 is rapidly reset for positive voltages. A simplified circuit (Fig. 2, not shown) differs from Fig. 1 mainly in the biasing circuit for the limiting diodes 118 and 120 and in the replacement of transistors 34 and 44 by common emitter stages respectively.

Title: Improvements in or relating to machines for the extraction of oil from seeds, nuts and the like
IPC: B30B9/24
Filed: 1931-05-22
Abstract: <PICT:0379294/III/1> <PICT:0379294/III/2> A method of extracting oil from nuts, copra, seeds, &c. consists in passing the seeds between a pair of conveyer bands disposed about a plurality of alternate fixed and adjustable rollers, the adjustable rollers being adapted to be placed into pressure relation with each pair of adjacent fixed rollers.  The bands may, in addition, be passed between rollers in a solvent or alkali bath.  As shown in Fig. 1, rollers 2, 3, 4 are mounted in stationary bearings and rollers 9, 10 are mounted on a bell-crank lever 15 pivoted on the axis of the roller 3.  An endless belt 20 passes around a pulley 5, under roller 2, over roller 9, under roller 3 and over roller 4 back to pulley 5.  Similarly a belt 21 on a pulley 6 passes around the rollers.  Grain or seed is supplied by a hopper 22 to a space A between the two belts and is thus crushed between the belts as they pass between the rollers. If oil-bearing seed is being crushed then a chamber 1 surrounds the rollers and is provided with a central partition 25 and a cold and hot oil inlet 23, 24 respectively, the rollers 10, 4 being heated. In Fig. 2, cold, hot and solvent extraction are provided for, the belts 20, 21 passing over rollers 26, 27, 28 in a solvent bath 1a provided with inlet 37 and outlet 38.  The oil-laden solvent is pressed out by the rollers 26, 27, 28 and is replaced by fresh solvent, and when the bands pass out of the bath a drying pressure is applied at 30 and the exhausted seed tissue removed by scrapers 35, 36.  The inlet 37 and outlet 38 are so adjusted as to allow sufficient solvent to enter the bath to absorb the oil in the seed tissue.  The belts may be perforated when grinding grain and may run at different speeds.
