IPC: G06C1/00
Filed: 1970-05-27
Abstract: 1292688 Supporting calculating machine components within casing X HEINE & SOHN KG 27 May 1970 25532/70 Heading G4B A calculating machine casing is made integrally with rails 4 and 3 and brackets 2, Fig. 1, which together support a totalizer assembly 14 for sliding movement transversely of the casing. The transverse position of the assembly 14 may be adjusted manually in accordance with the decimal point location, and the adjusted position held by a catch 51 engaging one of a number of recesses 53. All the machine components are of pressed or injection moulded plastics material and some may be connected together by plug or snap connectors; the main shaft 6 and a shaft 54 are held by lugs 5a and 12, formed integrally with the removable casing lid 13, in bearing recesses formed at the free ends of lugs 5 and 7, formed integrally with the casing body. In operation a number is entered using differentially set slides 36, which are held by resilient detents 38 engaging notches 39. Each slide 36 carries a rack 37, which through gearing 8, Fig. 8, shifts a rack 9 which engages teeth 69 on a disc 34, Fig. 7. The disc 34 rotates on a bush 10a carried by a disc 10. On rotation, a cam surface 59 urges a number of yieldablycarried tags 33a (the number being equal to the number set in the particular order) into corresponding recesses 70 on disc 10, where they are held by detent means (not shown). The main shaft 6 is now shifted to the right, to align the set tags 33a with the respective totalizer operating pinion 31b, Fig. 5, and to free a notch 32a from a lug 1a and to pivot a lever 46, Fig. 8, to fix the racks 9 with lugs 49. The main shaft is then rotated either by hand or electric motor to enter the number set into the totalizer pinions 17. Tens-carry is effected when a projection 17a trips a lever 16, which acts through a lever 15 to shift a pinion 31 into alignment with a carry tooth 11 formed on disc 10. The main shaft 6 can be rotated in either direction to effect either addition or subtraction. The tens-carry mechanism is reset by cams 72 engaging lugs 28b, Fig. 6, to shift a plate formed with recesses 28a in which levers 15 engage. The set tags 33a are positively withdrawn from the recesses 70 by a member 34b carried on a disc 34. To zeroize the totalizer, a shaft 20 is rotated, whereupon the leftmost of a number of pins 19 rides up a cam surface 22 to shift the shaft 20 to the right and engage the other pins 19 with projections carried by the totalizer wheels.

Filed: 1965-06-18
Abstract: 1,086,273. Machine tool details. SUPERIOR ELECTRIC CO. June 18, 1965 [June 26, 1964], No. 25806/65. Heading B3B. [Also in Division G4] A machine tool positioning system comprises electrical control means to ensure that the tool approaches the desired position always form the same direction. The tool-positioning motor is stepped by clock pulses, the number of steps necessary to reach the desired position being set on decade switches. The pulses are counted and, for movement in one direction, the pulse generator and hence the tool stops when the counter and the number set on the switches agree. For movement in the other direction, the pulse generator is not stopped at this point. Instead the counter is reset to zero and counts to a value pre-set on another switch and indicative of an amount greater than the backlash, the tool being moved past the desired position. The tool is then returned, in the first direction, to the desired position under control of the counter and the pre-set value.

Title: Process for the recovery of gallium
IPC: C22B3/38
Filed: 1961-07-17
Abstract: Gallium is extracted from a hydrochloric acid solution of concentration 2 to 10 N, preferably 4 to 7 N, containing gallium, iron and optionally aluminium, the ratio of ferric to gallium ions being at least 10, by extracting the solution with a C3 to C6 trialkyl phosphate, especially tributyl phosphate, optionally in an organic solvent, e.g. kerosene, in an amount less than equivalent, i.e. one ion of Fe to three mols. trialkyl phosphate, to the amount of iron in solution.  The extraction may be performed countercurrent, multistage.  The optimum acid concentration depends on the amount of iron present and is discussed.  In the examples, the use of tributyl phosphate in batch and countercurrent processes is described, using the tributyl phosphate neat or diluted with kerosene or ligroin.  The organic solvent phase is extracted with water thereby transferring the gallium and iron into the aqueous phase achieving a concentration of the gallium with respect to the iron.

Title: Improvements in or relating to electric pulse time modulation systems of communication
IPC: H04J3/00
Filed: 1946-08-30
Abstract: 621,063. Multiplex pulse signalling; pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. Aug. 30, 1946, No. 26211. Convention date, Sept. 1, 1945. [Class 40 (v)] In a pulse-modulated communication system each pulse carries one time modulated signal on the leading edge and another different timemodulated signal on the trailing edge. Transmitters. A sine wave 4, Fig. 2, from the generator 1, Fig. 1, is passed to both the modulator clipper 5 and, through a phaseshifter 15 producing wave 18, to the modulator clipper 19. Signals A and B, supplied at 2 and 3 respectively, modulate the two base waves to produce trains of pulses 6, 27, in which both the leading and trailing edges of the pulses are modulated according to their respective channels. These waves are then differentiated at 7, 30, to produce waves 8, 33 which are then clipped so that only the leading edge pulses 10, 36 pass to the mixer 13. The mixed output passes to a multi-vibrator 44 which produces pulses 47 having edges 48, 49 modulated according to signals A and B respectively. In an alternative embodiment, Figs. 3 and 4 (not shown), from a basic pulse wave, two sets of saw-tooth waves are produced, one with a sloping leading edge, the other with a sloping trailing edge. From these, two sets of pulses are produced, one set being time-modulated at the leading edge by signal A, the other being time-modulated at the trailing edge by signal B. These two sets of pulses are added to form a doubly modulated pulse as before. Receiver. The received wave 79, Fig. 5, passes through a differential network 80, where the leading edges of the pulses form positive pulses, and the trailing edges negative pulses. The positive pulses are clipped at 86 and demodulated at 88 to give signal A. The negative pulses are inverted at 90 before being clipped and demodulated to give signal B. In the demodulator the pulses become amplitude-modulated by mixing with a suitable sine wave from generator 95 and are then passed through a low pass filter 99.

Abstract: 522,353. Treating grain. HUZENLAUB, E. G., and ROGERS, J. H. Sept. 9,.1938, No. 26394. [Class 58]  In order to toughencereals to as to increase their resistance to attacks of insects, fungi &c. during storage, the grain is wholly or partially gelatinized by the action of heat and water and/or saturated steam, the process of treatment being carried far enough to toughen the grain without destroying its integrity. and the grain is subsequently dried to natural moisture content. The grain may be steeped in warm or hot water for a period of time sufficient to enable the water to penetrate into the core of the grain, and the steeping process may be carried out under pressure. After being steeped in water, the grain may be subjected to a further treatment in which steam is injected into a closed vessel containing the grain so that the steam acts directly on the grain to cause water to condense on it, the steam pressure being allowed to rise and then being reduced, this treatment being repeated one or more times, after which the grain is dried to natural moistening content. The grain may be treated in a closed vessel with steam alone, the pressure of the steam being raised and suddenly lowered one or more times. Cooling water may be admitted to the vessel so as to wet the grain to promote the condensation of further water on the grain during the steam treatment. The closed vessel may be exhausted of air prior to the admission of steam or water.
