Title: Improvements in or relating to a device for measuring values of electric or other quantities
IPC: G01R19/00
Filed: 1965-09-07
Abstract: 1,102,335. Voltage measurement. ZKL VYZKUMNY USTAV PRO VALIVA LOZISKA V BRNE. Sept. 7, 1965 [Dec. 5, 1964], No.38120/65. Heading G1U. A device for measuring electric voltages or other quantities such as the dimensions of a test piece after translation thereof into corresponding voltages comprises an electric circuit including two capacitors 1, 2 and a rectifier 4. The capacitors 1, 2 are charged to an input voltage Uv proportional to the instantaneous magnitude of the measured dimension of e.g. a test piece. When the measured dimension is a maximum, giving a voltage U max, switches 11, 12 are reversed to disconnect capacitor 1, short circuit rectifier 4 and remove the short circuit from a rectifier 5 so that as the voltage Uv drops the voltage across capacitor 2 follows it until the input voltage is a minimum U min. The difference between the voltage of the capacitor 1, U max and the voltage of the capacitor 2, U min shown as Uo may be measured in known manner and the capacitors 1, 2 may be connected in series by switches 21, 22 to give a voltage U min + U max shown as Us2 which is equal to double the mean voltage Us. In a modification, Fig. 1b (not shown) the function of rectifier (4) is reversed by switches (13), (14) so that it may be used instead of rectifier 5 to regulate the voltage of capacitor (2) to the minimum voltage.
Patent GB-904882-A (GB)
Title: Method of making fluorite
IPC: C01F11/22
Filed: 1959-11-11
Abstract: Fluorite is purified by reacting the impure fluorite with hydrogen fluoride in an amount sufficient to convert a preselected amount of impurities into flourides.  The fluorite may be mixed with aqueous HF at 80 DEG  - 150 DEG C. so that the fluorite is wetted, but not kneaded.  The HF may be sufficient to convert silica to SiF4, which is evolved with carbon dioxide, and other impurities to fluorides insoluble in HF.  The aqueous HF may be the "acid drips" or impure initial condensate at 20 DEG  - 40 DEG C. from an HF plant, containing H2O, H2SO4, HF, H2SiF6, and fluosulphonic acids. Alternatively, the fluorite may be treated in gaseous suspension at 150 DEG  - 500 DEG C. by passing gaseous HF through a fluidized bed of fluorite.  The purified fluorite may be reacted with H2SO4 to form pure HF.

Patent GB-990582-A (GB)
Title: Improvements in and relating to the production of polyethylene
IPC: C08F10/00
Filed: 1961-10-31
Abstract: The production of polyethylene from ethylene gas by a high pressure process is regulated by superimposing on the gas flow through a reactor pressure pulses, the reaction product being fed through a reduction valve into a trap operated at high pressure from which polyethylene and unreacted ethylene gas are withdrawn, measuring the pressure inside the reactor entrance and after analogue transformation this is fed as the momentary value into a pressure regulator connected with the reduction valve, measuring the temperature inside the reactor and after analogue transformation this is fed as the momentary value into a temperature set value regulator whose output reduces the set value of the pressure regulator when a predetermined temperature as adjusted on the temperature set value regulator is exceeded by the momentary temperature.  The pressure measured in the reactor may be fed, after analogue transformation, into a derivative controller whose output is proportional to the momentary rate of change of the pressure and when the controller reaches a predetermined output a signal is produced by the controller whereby the reduction valve is opened to a predetermined extent through a switch.  Alternatively, the pressure may be fed into a signal emitter of adjustable signal amplitude and the reduction valve is closed by this when a predetermined value is reached. The temperature measured in the reactor, after analogue transformation, may be made to act on the reduction valve through a derivative control, a switch and optionally a signal emitter. An electronic gate associated with a stable electronic oscillator may be opened by the switch and controlled synchronously with the signal and depending on the open time of the gate which is electronically measured, the cadence of the pressure pulses is adjusted so that the longer are the open periods, the more rapid is the cadence of the impulses and vice versa.

Abstract: 1408263 Still with cooler NEIL & SPENCER Ltd 22 Nov 1972 [27 Aug 1971] 40339/71 Heading B1B [Also in Division Dl] In order to remove residual heat from a still 14 after a heating means is turned off, solvent circulates between the still 14 and a cooler 18 through a liquid passage 38, controlled by a valve 36, and a vapour duct 16 thereby preventing the interior temperature of the still from rising. Solvent after use in a dry cleaning drum 2 passes into the still 14 which is heated until a float 34 in a storage tank 8, which collects the solvent liquid condensed in the cooler 18, operates a switch to cut off the heating and opens the valve 36 to cool the still. To ensure that the cooler is not empty when the valve 36 in the passage 38 is opened, the outlet pipe 24 from the cooler to the tank 8 extends above the bottom of the cooler, but to a lower height than a weir 20 which prevents liquid solvent entering the duct 16.

Title: Improvements relating to magnetic core memory matrices
Inventor: MATTHEWS GEORGE ARTHUR
IPC: H04Q3/42
Filed: 1958-12-15
Abstract: 900,033. Digital electric calculating apparatus. ERICSSON TELEPHONES Ltd. Dec. 15, 1959 [Dec. 15, 1958], No. 40396/58. Class 106(1). Data characters stored one to a column of magnetic core matrix 10 are read out to single character temporary stores 13, 14 and are rewritten in matrix 10 either unmodified, from store 13, or modified from store 14, depending on the presence of a signal controlling a gating device. It is preferred that decimal digits are stored in matrix 10 in the 2-out-of-5 code and in the stores 13, 14 which also comprise magnetic core arrays in 1-out-of-10 code. The connections of the read-out windings from store 14 are such that if the digit is re-written from store 14 into matrix 10 it is incremented by one. An additional temporary store may be provided in order to decrease a digit by one. The columns of matrix 10 are read out sequentially to stores 13, 14 under the control of matrix 11, described in Specification 875,875, causing pulses to appear on the two read-out lines of ao to do associated with set cores. The read-out lines are associated in pairs with cores of stores 13, 14, in such a way that when a switching pulse is applied on line 16 to all cores all except one core from each store is inhibited and one core from each store is switched (for simplicity the Figure shows storage of numbers of radix 6). A monostable flip-flop H controls gates through which pass pulses from source 17 on lines 20, 21 to read-out lines 22, 23 of stores 13, 14 respectively. If the digit read from matrix 10 is to be modified, a signal on terminal I switches the flip-flop H and opens gates G1, G2 otherwise gates G3, G4 are open. A pulse on line 20 is applied to one of the stores, 13 in the presence of the signal I, 14 otherwise, to clear the store. This leads to the generation of halfwrite currents in two read-out lines associated with the set core and threading two rows. The sequencing matrix 11 does not at this time produce a column half-write current and cores of matrix 10 are not switched. A pulse then issues on line 21 from source 17 in synchronizm with a pulse from matrix 11 to clear the other store and two cores of the column from which the digit was read are switched to store the digit in unmodified form if store 13 is cleared by the pulse on line 21, modified by the addition of one if store 14 is thus cleared. Modifications of the temporary stores are described. The gating device may include magnetic cores. Specifications 828,483 and 829,812 also are referred to.

Title: Water softener system
IPC: B01J49/00
Filed: 1971-08-31
Abstract: 1354754 Delivering measured quantities of liquid ECODYNE CORP 31 Aug 1971 [4 Sept 1970] 40499/71 Heading B8N [Also in Divisions C1 F2 G1 and H1] A meter 14 for delivering a predetermined proportion of water from a soft water flow line of a water softening system comprises a first valve 106 which opens to pass a proportion of the water in the flow line to a collecting chamber 97 via ports 90, 98, a second valve 107 which opens to deliver the contents of the chamber via ports 98, 96, means such as a spring-urged piston 114 for delivering the collected water through the second valve, a drive shaft 76 driven at a rate proportional to the volume of water passing through the flow line as by gearing 75 and a shaft 74 connected to a flow meter 73, a cam 80 rotatable by the drive shaft, and a cam follower 85 which oscillates to move the valves such that when one is open the other is closed. The meter 14 has a service outlet 17 and an inlet 18 which is connected to a resin tank 16 containing a bed of ion exchange particles for softening the hard water supplied through an inlet 11. The speed of rotation of the shaft 74 driven by the flow meter 73 is reduced by the gearing 75 and the cam follower 85 operates in a cam track 81 to pivot a lever 82 about a pin 83 and move the valves 106, 107. With the valve 106 open and the valve 107 closed water passes through the ports 90, 98 to the collecting chamber, the fluid pressure forcing back the piston 114 against the action of the spring 115. Upon closure of the valve 106 and the opening of the valve 107, the piston moves to deliver the collected water through the outlet 96 for discharge through pipes 15, 25 to a brine tank 26. The volume of the collecting chamber 97 may be adjusted by a screwed stop 112. When the level in the brine tank reaches the level H the system is ready to be regenerated by passing the brine solution in the tank 26 via pipe 24, aspirator 23, pipe 28 and control valve 12 into the resin tank 16, the solution being drawn up from the tank 26 by the Venturi effect in the pipe 24 created by directing hard water to the aspirator 23 from the control valve via pipe 27. The regeneration cycle is initiated by a timer 20 activating the control valve 12, the timer being set to operate once each day. If the level is blow the level H at the set time, the regeneration cycle for that day is skipped; when the level reaches the level H air trapped in pipe 33 causes a diaphragm in a timer activator 30 to lift an arm into the path of a contact pin (42) of the timer, Fig. 2 (not shown). In the brine tank (26) Fig. 3 (not shown) the water collected by the meter 14 passes down the pipe 25 disposed within an enclosure (32) having slots (34) which permit the flow of water to and from the contents of the tank. When suction is applied to the pipe (24) the valve (65) is drawn down off its seat to allow the water to pass through a slot (56) and up through a passage (61) until the passageway is blocked by a floating ball valve at the water level (L).
