Title: Method of and apparatus for exhausting and filling electric gaseous discharge devices
IPC: H01J9/38
Filed: 1953-12-31
Abstract: 779,055. Actuation of switches. SYLVANIA ELECTRIC PRODUCTS, Inc. Dec. 31, 1953 [Dec. 31, 1952], No. 36395/53. Class 38(5) [Also in Group XL(a)] A multiple contact switch is used for automatically controlling the sequence and duration of a number of separate operations which are independent but may overlap in time. The switch shown is designed to control five such operations, corresponding to various steps in-the processing of a long tubular fluorescent lamp. Each of the spring contacts 158 A, B, C, D, E, bears against a copper plate 132, and completes with the secondary of a transformer a circuit which maintains open a relay in the primary circuit, there being five separate relay circuits in all, one corresponding to each spring contact. Set out on the plate 132 are an ordered sequence of strips of insulating tape 156 A, B, C, D, E. A motor-driven rack and pinion moves the plate from left to right. As insulating strip 156A moves under contact 158A, the secondary circuit is broken, so that the first relay closes to energize a solenoid controlling the first operation. Strip B then operates to begin the second operation, and strip C the third, these three operations now proceeding simultaneously. Strip D reaches contact D just after strip A leaves contact A, so that the first operation terminates just before the fourth begins. Strip C now disengages from its contact, so that the third operation terminates. The thin strip E momentarily energizes its corresponding solenoid for the fifth operation, which is very short. Strip B then disengages, terminating the second operation, leaving the D circuit operating alone, until that also terminates. U.S.A. Specification 1,842,624 is referred to.

Patent GB-889256-A (GB)
Title: Improvements in or relating to methods for the production of water-insoluble fatty acid salts of polyvalent metals
Filed: 1958-11-14
Abstract: Water-insoluble polyvalent metal salts of saturated or unsaturated fatty acids having at least 12 carbon atoms are obtained by precipitation from aqueous solutions, precipitation being effected by reacting, with stirring, on the one hand an aqueous solution of a mixture of a sodium or potassium salt of such fatty acid and sodium or potassium carbonate, the mixture being made by saponifying the fatty acid with an excess of sodium or potassium carbonate, with, on the other hand, an acidified aqueous polyvalent metal salt solution, and separating, washing and drying the precipitate.  In one embodiment the fatty acid is saponified with an aqueous sodium or potassium carbonate solution at a temperature of 18 DEG F.-54 DEG F. above the titer of the the fatty acid and the concentration of the resulting soap solution should be 5% to 20% and the solution should contain an excess of 2%-10% of sodium or potassium carbonate, and an acidified polyvalent metal salt solution of a concentration of 5%-30% and a pH value of 3-5 is then added to the aqueous soap solution kept at saponifying temperature.  Acidification of the metal salt solution is suitably effected with a relatively strong acid, e.g. sulphuric acid or hydrochloric acid is used when the metal salt is a sulphate or chloride.  The carbon dioxide generated in the process enables a finely grained precipitate to be formed.  The first embodiment may be carried out in a continuous manner by leading the solutions via conduits to the middle of the reaction container, the precipitated product which rises to the surface being drawn off whilst the residual waste solution continuously flows out from the lower part of the container.  Specified fatty acids are palmitic, stearic, arachidic and behenic acids, and mixtures thereof, and oleic acid, and specified polyvalent metals are Mg, Zn, Ca, Al, Sr, Ba and Cd. In a second embodiment of the invention the acidified metal salt solution is added as quickly as possible to the soap solution formed from the fatty acid and the precipitated metal salt may be washed with a mixture of an organic solvent, e.g. alcohol and water.  The metal salt product, after washing, may be dried at an elevated temperature below its melting point, or by freeze-drying or vacuum drying.  The precipitation process may be carried out in the presence of water-insoluble finely dispersed substances, e.g. bone meal.  The first embodiment may suitably be carried out in a device comprising a reaction container consisting of a reaction pot into which the acidified metal salt solution and the soap solution are introduced via separate conduits, the pot being provided with a stirrer.  The second embodiment may be conducted in a device comprising a plurality of reaction chambers, e.g. two or three to which the soap solution and the metal salt solution are fed alternatively.  Examples are given for the production of magnesium stearate, zinc stearate, calcium palmitate and magnesium oleate.

[Also in Division B3] In a method for removing material from a workpiece, e.g. a resistor or capacitor, an abrading apparatus removes material from a workpiece by means of a high velocity jet of airborne abrasive particles and comprises a means of continuously monitoring the electrical value of the element while the jet is moving across the element, and a further means of measuring the rate of change of said electrical value, as a result of which the direction of the jet is reversed immediately prior to the required value being reached to take account of the finite time taken for reversal. Abrasive powder from a reservoir 20 is mixed with compressed air at about 85 p.s.i. from a compressor 18 in a chamber 16 and is vibrated by a vibrator 22. The abrasive particles pass through a solenoidoperated pinch valve 24 to a nozzle 12 which is directed on to the workpiece 10 on a holder 32. Nozzle 12 is caused to pass back and forth across the workpiece by means of a rotatable arm 30 on which is journalled the nozzle holder 26. The traversing mechanism 28 comprises an electric motor which causes movement of arm 30 first in one direction and then in the opposite direction upon completion of the abrading operation. Also at the end of each operation the pinch valve is automatically closed. Units 24 and 28 are controlled by a control unit 36 which is connected to the workpiece to measure the electrical value thereof. Vibrator 22 may also be connected to the unit 36 to control the concentration of abrasive particles by altering the amplitude of the vibrations. Control unit 36 may incorporate a 4-wire resistance limit bridge for monitoring the electrical value of the workpiece. Mechanism 28 includes a device for translating the rotary motion of the motor into a horizontal motion which is imparted by means of plates to arm 30 (Figs. 3 and 4, not shown).
