Title: An improved process for treating soya beans
IPC: A23L11/30
Filed: 1932-09-15
Abstract: Soya beans are alternately subjected to the action of steam and then to the influence of drying, the alternate treatments being repeated until the substances of the nature of ethereal oils which cause the bad taste and smell and also rancidity are removed.  The beans, although they may be swollen before the above-mentioned treatment, are preferably kept from swelling during the treatment with steam. Ammonia, alkalies, sugar, or other substances having an anti-coagulating effect may be admixed with the steam or dissolved in the liquid used to bring about the initial swelling of the beans.  In a specific example husked soya beans are heated in the dry state to 80-90 DEG  C., and are then passed through a jacketed vessel divided into several compartments; a current of steam at about 100 DEG  C. and a current of dry air heated to about 40 DEG  are passed through the compartments so that a compartment traversed by the steam is followed by one traversed by the air; ammonia may be admixed with the steam.

Filed: 1973-06-04
Abstract: 1379347 Welding by pressure HILTI AG 4 June 1973 [23 June 1972] 26540/73 Heading B3R  In a condenser-discharge stud welding tool a counter is provided which is operated only when the condenser is completely discharged with a time factor for the discharge corresponding to the time factor for a welding operation. A stud welding tool 1, Fig. 1, has a condenser 3 chargeable from a D.C. source 2, a partial or slowdischarge switch 10 with resistor 9, a welding switch 8 for connecting the condenser to welding electrodes 7 and a counting circuit connected in parallel with the condenser 3. The counting circuit includes a threshold relay 13, resistor 12 and capacitor 11, the threshold value of the relay 13 being such that upon slow or partial discharge of the condenser 3 (caused by closure of the switch 10 and controlled by resistor 9) the current in the counting circuit is too low for the relay 13 to operate the pulse controlled counter 14. Similarly when the condenser 3 is charging the current in the counting circuit is too low to operate the threshold relay 13 and counter 14. Alternatively (as shown) a diode 15 is included in parallel with the relay 13 and is poled so that charging current does not flow through the relay 13. Discharge of the condenser 3 for a welding operation-is accompanied by discharge of the condenser 11 and the current flow in the counting circuit is then such that the relay 13 and counter 14 are operated to record one welding operation. In the counting circuit of Fig. 2 a breakdown diode 16 only becomes conducting in the conditions of discharge of the welding condenser 3 for a welding operation. In alternative circuits (Figs. 3, 4, not shown) the counting circuit is inductively coupled to the welding line and in one circuit (Fig. 4, not shown) a separate condenser charging line is provided which is disposed away from the inductive coil of the counting circuit so that charging currents do not register a count on the counter.
