Title: Crude sugar liquor defecation process.
Inventor: BODE HAROLD ELI
IPC: C13B20/02
Filed: 1967-04-17
Abstract: 1,179,913. Purifying sugars. H. E. BODE. 17 April, 1967 [18 April, 1966], No. 17568/67. Heading C2C. [Also in Divisions A2 and C6] A process for defecating a crude sugar liquor comprises forming a heated mixture of the liquor, a phosphated starch and an alkaline earth metal defecating reagent, the reagent being sufficient to make the liquor alkaline and to cause precipitation of the alkaline earth metal derivative of phosphated starch and impurities in the liquor, and removing the resultant precipitate. The phosphated starch may be obtained by phosphating a pure starch e.g. corn, wheat, tapioca, rice, milo, waxy maize and potato starch, or a starch-containing material e.g. degerminated corn meal, wheat flour, crude amylose, or crude dextrin. The liquor may be obtained from vegetables and fruits and may be a cane, beet, wood or corn sugar liquor, molasses, or a starch or other carbohydrate hydrolysate liquor. The defecating reagent may be the oxide, hydroxide or carbonate of calcium or barium. The impurities include bagasse, bagacills, proteins, polypeptides, amino acids, pentosans and waxes. The separated, precipitate may be used as animal food. In Example 4 a cane molasses liquor after treatment with phosphated starch obtained by phosphating corn meal, lime and optionally phosphoric acid to defecate it, is inverted with Invertase enzyme. The inverted liquor is subjected to bone black refining and vacuum concentrated. In Example 5 a cane sugar liquor is defecated using phosphated corn starch and lime, subjected to vegetable carbon and ion exchange resin refining, vacuum concentrated and used to produce liquid blends of sucrose and dextrose. The process may also be applied to the treatment of molasses produced during refining of crude dextrose liquors (Hydrol).

In a receiver for an inductive selective calling system, the audio-frequency calling signal received by the pick-up coil A is amplified at T1, T2, overloading with a high input signal being presented by feeding back the resulting potential change across R6 to the base of transistor T1, negative feedback also being applied from the collector of T2 via resistor R3 to the emitter of T1 to ensure stability. The output from the collector of T2 is supplied to a circuit S resonant to the desired frequency, the selectivity and sensitivity of this circuit being increased by positive feedback via an adjustable resistor P1 from the emitting circuit of transistor T3 acting as a negative resistance. The output in the form of half cycles of sine wave from the emitter circuit of T3 is supplied via an impulse-forming circuit T4, transformer TP1, and switch K to trigger a normally cut-off oscillator T5 and operate an acoustic device L. In its alternative position the switch K allows the reception of speech via capacitor C7 and T5 operates as an amplifier. A temperature sensitive resistor NTC compensates for temperature changes. An indicator lamp may be included in the output circuit of oscillator T5.

Overloading of an engine driving a ships variable (reversible) pitch propeller is prevented by a cam A connected to a controller or the engine fuel pump actuating a contactor 1 which de-energizes a solenoid operated valve E1, thereby stopping flow to and from the hydraulic ram V of the pitch changing mechanism, thus arresting change of pitch, further movement of the cam A resulting in further overload actuating a second contactor 2 which causes energization of the valve E1 resulting in supply to the hydraulic ram V in a direction to bring about a change of pitch in the reverse direction, i.e. if blade pitch is being increased actuation of contactor 1 arrests the increase and subsequent actuation of contactor 2 will then reduce the pitch. Hydraulic supply is through a valve E2 which is closed on operation of the contactor 1 so that the supply is through a restricted by-pass RD, the ram V thus operating slowly in the overload range. Reversers I1-I4, normally open when the ram V is in the zero pitch position, are closed one way or the other by a cam B whose movement corresponds to the movement of the ram V when the latter is in a position corresponding to ahead or astern pitch.

Abstract: 823,864. Counting apparatus; zeroizing mechanism. VEEDER-ROOT Inc. June 14, 1956 [July 6, 1955], No. 18440/56. Addition to 776,014. Class 106 (1). In the counter disclosed in the parent Specification there is the possible disadvantage that if, after a dispensing operation, one of the numeral wheels comes to rest near the zero position the said wheel may be locked to the associated resetting gear and to the supporting shaft, thus locking the whole mechanism and preventing resetting. This disadvantage is avoided according to the present invention by having the pick-up member 310, Fig. 9, of each numeral wheel frictionally coupled to the resetting gear 306. The disadvantage could also be overcome by elongating the holes 112, Fig. 7, of the pickup disc 104 which is integral with the resetting gear. The profile of the control cam 134, Fig. 1 (not shown), which effects longitudinal movement of the counter-shafts for resetting, is modified so that the shafts are longitudinally moved to condition the numeral wheels for resetting and are then given a slight retracting movement to reduce the side thrust on the numeral wheels. Specification 684,047 also is referred to.
