Title: Improvements in coin-operated cocks and valves for controlling the supply of fluids
IPC: G07F15/00
Filed: 1937-02-18
Abstract: 487,965. Coin-operated valves. WILSON GASMETERS, Ltd., G., WILSON, J. H., and POOLE, D. C. E. Feb. 18, 1937, No. 4859. [Class 27] In a coin-operated cock or valve for controlling the supply of fluids in which the movable member of the valve is coupled to an operating handle by means of a coin, the movable member is entirely enclosed in a casing closed by a removable cap adapted to be locked against unauthorized removal. In Fig. 2, the casing comprises a tubular extension c to the valve body a, and a cover h for the bottom of the valve. The removable cap e is secured to extension c by pin and bayonetslot connections el, e<2> and is locked together with cover h by clamps g terminating in perforated lugs g<2> held together by a padlock. The cap e carries a rotatable operating member d fast with a handle d<1>. A coin inserted through a slot in extension c enters slots d<2>, b<2> in member d and the stem b<1> of the valve plug b, and couples them together to enable the valve to be opened and closed by the handle d<1>. The cover C is removable by an authorized person to enable the coin to be withdrawn and the valve closed. In Fig. 3, the bottom cover h is permanently secured in position, and the removable cap e has a perforated lug e<3> by which it is padlocked to a perforated lug n on extension c. Coin-slit closing-devices.-In Fig. 3, a sleeve k is interposed between the casing c and the coin coupled parts b<1>, d. A slot k<2> in the sleeve initially registers with the coin slot f in casing c to enable a coin to be inserted. When the valve is opened by operation of handle d<1> the coin engages one side of the slot k<2> and turns the sleeve to mask the insertion slot. The valve may now be opened and closed at will without moving the sleeve from its slot-closing position, since an aperture k<1>, opening into the other side of slot k<2>, enables the coin to clear the sleeve when the handle d<1> is operated, but is too narrow to permit the coin to pass through. In this way unauthorized withdrawal of the coin after the valve has once been opened is prevented.

Title: Improvements in or relating to multi-contact electric tumbler switches
IPC: H01H23/16
Filed: 1933-02-18
Abstract: 394,920. Tumbler switches. GAVORET ET CIE, G., 21, Rue Dautancourt, Paris. Feb. 18, 1933, No. 5063. Convention date, April 8, 1932. [Class 38 (v).] The movable contact springs 1 are embedded in the base 13 and have their free ends con nected to an insu lating plate 7. A tumbler lever 6 has a reduced lower end 5 projecting througl a hole 4 in a spring plate 3 fixed at its ends to the insu lating plate 7. Thus on moving the tumbler 6 the spring 3 is compressed and the plate 7 is moved past the dead-centre position to cause the contact springs 1 to engage one or other of the sets of fixed contact springs. In a modification, the ends of the spring 3 bear on the centres of two similar springs which are mounted on the plate 7. In another modification the lower end of the tumbler lever is flattened to allow the switch to remain in the central position. Another modification is described in which the switch can remain only in the central and in one side position. The contact springs are mounted in the base by the method described in Specification 394,919.
Patent GB-981720-A (GB)
Title: Negative resistance logic inverter circuits
IPC: H03K19/10
Filed: 1962-02-09
Abstract: 981,720. Negative resistance logic circuits; STANDARD TELEPHONES & CABLES Ltd. Feb. 9, 1962 [Feb. 14, 1961], No. 5065/62. Heading H3T. A logic inverter comprises two circuit branches, each containing a negative and a positive resistance in series, one logic input signal switching both negative resistances to a low resistance state and the other logic signal switching one to switch to a high voltage state causing such an increase in current in the other as to switch it also to the high resistance state. The inverter stage comprising tunnel diodes 4 and 5 is controlled by a previous logical stage 8 which produces at 12 in response to a clock pulse at 13 a negative voltage (corresponding to a logical 0) or a substantially zero voltage (corresponding to logical " 1 ") depending upon which one of the tunnel diodes 9 and 10 is in the high resistance state. If a negative (" 0 ") output signal is produced at 12, diode 18 is non- conductive and a clock pulse from delay element 15 switches diode 4 to the low resistance state. As current drawn by this diode from a current source 25 is now relatively high diode 5 also switches to this state. Accordingly, the output voltage developed across diode 5 from the clock pulse is small and thus represents a logical (" 1 "). If, however, a logical " 1 " (zero voltage) had been present at 12, diode 18 would have been conductive and the clock pulse current would have caused diode 4 to switch to the high resistance state. The additional current now available from battery 25 causes diode 5 to switch to the high resistance state so that the resulting output voltage across diode 5 is a high value representing a logic " 0 ". The delay element 15 delays the clock pulse by an amount corresponding to the switching delay in circuit 8. In Fig. 2 (not shown) a further delay circuit is introduced between the circuit branches containing diodes 4 and 5 and an inductor is used as the current source 25, 26. Specification 922,580 is referred to.

Title: Improvements in or relating to the concentration of fatty acids in aqueous solution and to the recovery of said acids from aqueous solutions thereof by azeotropic distillation
IPC: C07C51/48
Filed: 1952-02-28
Abstract: <PICT:0735867/III/1> Aqueous solutions of aliphatic carboxylic acids containing 1 to 4 carbon atoms per molecule are concentrated by distilling the solution in a fractionating column operated in a continuous manner in the presence of a volatile hydrocarbon and an aliphatic ketone having 4 to 7 carbon atoms per molecule, whereby vapours comprising water, ketone and hydrocarbon pass over from the head of the column; these vapours are condensed, the condensate is allowed to separate into an aqueous phase and a non-aqueous phase, and the non-aqueous phase is returned to the head of the column. The aqueous phase is distilled in a separate column in order to recover a concentrated solution of the ketone, and this is blended with the aqueous acid fed to the main column.  When using butanone as ketone, the preferred volatile hydrocarbons are benzene and cyclohexane. When using a C5 ketone, the preferred hydrocarbons are methylcyclohexane and n-heptane. Aqueous acid fed through line 9 is blended with concentrated aqueous ketone supplied through line 10; and the mixture is passed through preheater 1 into column 2 which is heated by reboiler 3. The overhead vapours are condensed in condenser 5, the condensate being collected in separator 6.  The upper layer of the condensate is returned to column 2 through line 14.  The lower layer is passed through line 15 to column 7 where it is stripped with steam introduced through line 19.  Ketone vapours are removed overhead from column 7, and are condensed.  Part of the condensate is returned as reflux to column 7, and the remainder is passed through line 10 to be blended with fresh aqueous acid entering the system. Concentrated acid is withdrawn through line 12 from the base of column 2.  Waste water is withdrawn from the base of column 7 through line 18.  In an example, an aqueous mixture of acetic and formic acids is concentrated using methyl ethyl ketone and cyclohexane as auxiliary liquids.  A column equivalent to 40 theoretical plates is employed; and the feed is introduced half-way up the column.  The temperature at the top of the column is maintained at 66.5 DEG  C., and that at the base at 110.5 DEG  C.  The aqueous phase removed from the separator contains 9 per cent by weight of methyl ethyl ketone. This is distilled in a separate column to give the ketone/water azeotrope which is fed with the aqueous acids to the main column. The waste water contains no detectable quantity of formic or acetic acid.  The acid mixture withdrawn from the base of the main column contains less than 0.32 per cent by weight of water, and less than 0.25 per cent by weight of methyl ethyl ketone.
