Title: Process for the production and treatment of dried and edible vegetable products such as dried peas, beans, lentils and the like
IPC: A23L11/00
Filed: 1936-09-07
Abstract: Edible vegetable products which have been previously dried to preserve them such as dried peas, beans, and lentils are heated together with an aqueous solution of salts containing sodium or magnesium and hydrogen, carbonate and phosphate ions to between about 40-60 DEG  C.  The treatment may also be applied to fresh vegetable produce such as fresh haricot beans or small peas previous to drying to preserve them.  In an example dried peas are treated in a steam-heated double-bottomed vessel with an aqueous solution containing 2-4 per cent by weight of sodium phosphate and sodium bicarbonate which are in equi-molecular proportions. The solution is raised to 50-60 DEG  C. before pouring it over the peas and thus temperature is maintained for 3 hours by heating slightly at intervals.  The mass is allowed to return to room temperature and to soak for 17 hours after which the liquid is decanted and may be used again.  The peas are drained for an hour and then dried in warm air. Haricot beans, lentils &c. may be similar treated.  Fresh haricot beans or small fresh peas may be treated with the same solution which is first brought to 60 DEG  C. and then kept at 40 DEG  C. for 18 hours, after which the mass is washed, drained, stirred and dried.

Title: Improvements relating to spark machining apparatus
Inventor: HARRIS MICHAEL JOHN
IPC: B23H1/02
Filed: 1956-08-16
Abstract: 843,546. Cutting by spark erosion. G.K.N. GROUP SERVICES Ltd. Aug. 16, 1957 [Aug. 16, 1956], No. 25026/56. Class 83 (4). In a spark-machining apparatus wherein the spark gap between the electrode t and workpiece w is bathed in a cooling fluid, preferably a dielectric fluid, and the sparks are produced by the discharge of a condenser C<SP>1</SP>, the charging of the condenser is modified by imposition of an oscillating voltage generated in an oscillatory circuit L1, C<SP>2</SP> by shock excitation from the preceding spark whereby the voltage across the spark-gap after being initially carried below an arc extinguishing value by the condenser discharge, remains below or is carried below the arc extinguishing voltage for sufficient time to reduce the possibility of the arc persisting. Rectified but unsmoothed alternating current from a transformer T 1  and bridge rectifier w1- w4 is supplied through an inductance L3 and resistor R1. The length of the spark gap is controlled automatically by a motor m connected to the electrode t as described in Specification 843,548 and coupled in a control circuit as described in Specification 843,547; alternatively, the motor m may have a permanentmagnet field system. Following discharge an oscillating voltage produced by the circuit L1, C2 is superimposed on the normal charging voltage of the condenser to create a voltage wave 15, Fig. 3 (not shown), whose negative peaks fall below the arc extinguishing voltage during the deionization time of the spark-gap. In another embodiment, Fig. 2, oscillations are produced by a tunable condenser C<SP>3</SP> in " parallel " with a coil L2 wound on a ring M of magnetic material magnetically coupled in the discharge circuit. Both arrangements may be combined in a single circuit. A current limiting valve circuit may be used instead of resistor R1 and inductance L3. Specific examples are given.
