Abstract: 1,098,651. Drafting apparatus. IDEAL INDUSTRIES Inc. Aug. 18, 1965, No. 35504/65. Heading D1D. In a drafting apparatus, including gill boxes, pin-drafters, frames &c., drafting takes place in a compartment forming part of a closed circuit in which air circulates, the temperature and humidity of the air in the compartment being sensed and kept constant. In Figure 4, an airtight enclosure 50 with hinged access covers 71, 61 houses drafting rolls 16, 17 in two sets each comprising four fluted rolls and treating seven slivers..The slivers entering the compartment at 72 are engaged by a sealing-strip 83; they reach the rollers over a guide 20 and leave them by a condenser 73, calender rolls 25, 26 and a coiler head 27 before being collected as a composite sliver in cans 30. The rolls have suction clearer apparatus similar to that of Specification 835512 (heading D1D), by means of which air is drawn from the compartment through a duct 105 and through filter (124) by a fan (116), Figure 2 (not shown). When, as is the case during normal working, an outlet (133) is closed by a pivoted flap (145), the air is diverted past filters 176, 177, Figure 6, to a return channel having a heater 200 and so back to the compartment where the condition of the air is sensed by thermostats T, T<SP>1</SP> and a hygrostat 195, Water percolates over the filters 176, 177 from pipes 180, 181 supplied by a pump 185 from a reservoir containing a cooling-coil 203 and in which water is maintained at constant level by a valve 170. In the circuit before the filters 176, 177, is an airinlet normally closed by a flap 144. An electrical control circuit is described, Figure 10 (not shown), which is such as to prevent the roller driving motor (40) from being energized before the fan motor (121) is switched on. When thermostat T indicates that the air-temperature is too low, the heater 200 is switched-on; when thermostat T<SP>1</SP> indicates that it is too high, a cooling-unit controlling the coil 203 is switched-on, and when the hygrostat indicates that the moisture-content of the air is too low, a motor (186) starts up pump 185 to cause more water to flow over the filters 176,177. The water used in the apparatus may contain a treating, e.g. a lubricating, agent.

Title: Process for recovering tungsten values from alkaline solutions
Inventor: CHIOLA VINCENT
IPC: C01G41/00
Filed: 1968-07-25
Abstract: 1,240,524. Tungsten recovery. SYLVANIA ELECTRIC PRODUCTS Inc. 25 July, 1968 [2 Aug., 1967], No. 35596/68. Heading C1A. Tungsten is stripped from an amine/tungsten complex by an NH 3  gas-fortified aqueous solution of (NH 4 ) 2 WO 4  having a pH of between 10 and 11. As shown (Fig. 1B) the loaded organic extractant on leaving the solvent extraction process flows to a wash stage 16, in which the extractant is scrubbed with deionized water to dissolve any water soluble impurities such as Na 2 SO 4 . The scrubbed extractant is then transferred to the stripping column-contactor 18. The extractant and stripping solvent come into contact at the base of the column of flow co-currently upwards with agitation. After reaction the mix passes to a mixer-settler unit 20 which effects separation of organic and aqueous phases. The product, a concentrated aqueous solution of (NH 4 ) 2 WO 4 , flows from the base of unit 20; the product is then further treated to produce crystalline ammonium paratungstate { (NH 4 ) 10 W 12 O 41 .xH 2 O}. The stripped organic extractant is washed in unit 22 and passed to 24 for regeneration by dilute H 2 SO 4 . The regenerated organic extractant may be recycled. Wash water from stage 16 is used to dilute the H 2 SO 4  in stage 24. The temperature throughout the extraction and stripping circuits is controlled within the limits 20 to 60 C. The extractant is described fully. The ratio L/D, where L = length of stripping column-contactor, D = diameter, should have a value high enough for adequate contact between stripper and extractant to take place. Agitation is carried out in the contactor with propeller blades which are placed just above the inlet at the base.

Title: Improvements in Electronic Recirculating Stores
Inventor: TADDEI ROMANO
IPC: G06C21/02
Filed: 1968-07-29
Abstract: 1,184,989. Data storage device. ING. C. OLIVETTI & C. S.p.A. 29 July, 1968 [3 Oct., 1967], No. 36131/68. Heading G4C. An electronic store comprising a plurality of data registers and a marking register, all of the static recirculating type, has a marking signal in the marking register which determines which order, of the data recirculating in a data register, is to be operated on. Data from an accounting machine is fed via a staticizer SP, a transcoder TR and AND gates 2 to an adder S situated in the recirculation path of registers M1-M3. The accounting machine deals in numbers having twelve decimal digits so each register has twelve stages each storing a four bit binary coded decimal number, each register and the adder forming together a 13 stage recirculation path. The marking register is a single bit fourteen stage register having facility for re-entering the bit in either the twelfth, thirteenth or fourteenth stages. Operation.-During accumulation a signal from the accounting machine causes a bit to be stored in the least significant bit 1 of register RS and causes a circulation of register RS and one of the.registers M1-M3. The signal read out of register RS is in synchronism with the least significant digit in the register M which is fed to the adder. The bit from register RS causes AND gate 2 to be enabled and causes the least significant digit from the accounting machine to be added to the least significant digit of the register with any carry produced applied to store 6 to be added to the succeeding digit. At the same time a signal G is entered into the most significant stage of the register M. Only one digit and all appropriate carries are added per circulation and the marking signal is returned to stage 14 of the register RS so that gate 2 is enabled by the signal on CBS when the next least significant digit of register M enters the adder. The circulations continue until the most significant bit has been added to the register. Bead-out for printing or display purposes. In this case the marking signal circulates in the same stages as the signal G for the first circulation. At the end of the circulation the marking signal is fed to stage 12 of register RS to advance with respect to signal G. During each circulation a test is made to see if the stage in register M to the right of the stage corresponding to that in register RS carrying the marker signal carries a digit. When a digit is found circulation ceases when the G signal is emitted from register M. During a second phase of readout a digit is now emitted from the output U each time the marker signal is emitted from register RS to cause the contents of register M to be read out in decreasing order of significance.
