Title: Improvements in or relating to electrical information storage circuits
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04L25/04
Filed: 1950-09-29
Abstract: 747,811. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES, Ltd. Sept. 29, 1950, No. 23877/50. Class 40 (4). [Also in Group XIX] An electrical information-storage circuit (see Group XIX) comprises, in one form, interconnected magnetic trigger circuits for storing a binary number with means for progressing the pattern of operated and unoperated circuits in each direction, the direction of movement being selectable. Each order comprises two magnetic cores, Fig. 7, of a, material having a hysteresis curve, Fig. 6, of nearly rectangular form. If a pulse is applied to terminals IP across a coil wound on the core, the core is magnetized to a state K2 and, after the pulse, remains magnetized in a state K1 to represent the digit " 1 ". Now a pulse of opposite sign applied to terminals DP1 across a second coil will take the core from state K1 to K4 and will leave it in state K3, producing a pulse in an output coil OC. This pulse is passed by a rectifier MR46 to a coil on the second core to magnetize that core to represent the digit " 1 ". Now a pulse is applied to terminals DP2 across a second coil on this core to change the state of the core and produce an output pulse across an output coil connected to terminals OP. These terminals are connected to the input of the next order cores and the pulse produces a registration of " 1 " therein. A rectifier MR47 short-circuits the corresponding pulse produced in the first coil of the same order. If no pulse is received at the input terminals IP, the first core remains in state K3 representing the digit " 0 " and the shifting pulse applied to terminals DP1 will merely alter the state to K4 from which it will return to K3. No pulse will be produced in the output coil OC, the second core will remain in its zero registering state, and the shifting pulse applied to the terminals DP2 will have no effect. The first core of the next order will therefore receive no input pulse and will remain in its zero registering state. In the complete shifting circuit described, Fig. 8 (not shown), each pair of cores is connected through rectifiers to the next higher and next lower order pairs and a high potential is selectively applied to one .or the other of a pair of leads to block certain of the rectifiers thereby to determine the direction of the shift. The units of several orders may be connected to form a ring and the numbers stored may be continuously circulated by a succession of shifting pulses. The numbers may be read or modified at a selected unit in the ring.

Title: Method of producing a water soluble coffee concentrate
IPC: A23F5/18
Filed: 1957-07-29
Abstract: In the production of a coffee extract, an aqueous extract is prepared from disintegrated coffee beans and is then heated at an elevated temperature, below the boiling-point of water, in contact with an oxygeneous atmosphere for at least one hour until the soluble constituents of the coffee are oxidized.  When coffee is made from fresh coffee beans newly removed from the cherries, their parchment-like coats are washed after which the beans are comminuted and the coats dry and can be winnowed off.  The beans are reduced to a disintegrated homogeneous mass and then extracted by hot water, steam or the like and the solution is separated from the water insoluble constituents.  The water-soluble constituents are then oxidized by exposing the solution to the action of oxygen in an oxygeneous atmosphere, e.g. air, preferably using an inorganic catalyst, e.g. potassium permanganate.  The solution is heated for at least one hour, preferably at a temperature 15 DEG  to 20 DEG  C. below the boiling-point of water but not less than 30 DEG  C.  The solution is filtered and centrifuged, evaporated, preferably under vacuum and then spray dried. Alternatively, the catalyst may be omitted from the solution but supplied to the concentrate, e.g. potassium permanganate 0.01 to 0.03% by weight of the tannin-chlorogenic compounds in the concentrate, which is then heated to a temperature not lower than 30 DEG  C.  The spray drying is performed at as low a temperature as possible, e.g. the outlet temperature of the chamber, preferably does not exceed 60 DEG  C. Atmospheric or conditioned air may be admitted to the spray drying chamber.  After spray drying the powder is exposed to a normal roasting temperature.  Hydrogen peroxide or cupric oxide may be used instead of potassium permanganate.

Patent GB-395887-A (GB)
Title: Improvements in and relating to rectifier installations
IPC: H02H7/12
Filed: 1932-08-29
Abstract: 395,887. Rectifying alternating current. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Aug. 29, 1932, No. 24067. Convention date, March 26. [Class 38 (ii).] In a supply arrangement wherein a grid - controlled rectifier 2, Fig. 2, fed from an A.C. network 1, supplies a D.C. network through a choke 4, and having means for applying a negative potential to the grids in the event of short circuit or back ignition, the tendency of the choke to prolong ignition is overcome by means which, on the occurrence of the fault, connect a resistance or a charged condenser in parallel with the choke. Connected in series across the choke 4 are relay coils 7, 8 and a spark-gap 10 designed to breakdown at about 80 per cent of the normal D.C. voltage and resistances 11, 12. When a shortcircuit occurs the total D.C. voltage is applied across the choke 4, the gap 10 breaks down and current flows to operate relays 7, 8. The relay 7 applies a negative potential to the grids of the rectifier, and relay 8 operates with a time delay to connect the resistance 12 across the choke 4 to form a local circuit for the inductive current. This leaves the rectifier free to extinguish. In a modification shown in Fig. 4, a condenser 13 in series with a resistance 12 is connected between the rectifier cathode and the secondary star point of transformer 1 so that during normal working the condenser attains the D.C. network potential. When a short circuit occurs the relays 7, 8 operate, the relay 8 operating with a time delay to connect the condenser 13 across the choke 4. The time delay is adjusted so that the relay operates at the point C, Fig. 5, when the voltage has dropped to zero, to connect the charged condenser which discharges to supply the inductive current. This allows the rectifier to extinguish. A protective gap 14 and resistance 15 are connected across the choke 4.

Title: Method and apparatus of recording and reproducing electrical signals
IPC: H04N9/898
Filed: 1970-05-19
Abstract: 1316595 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 May 1970 [21 May 1969 (2)] 24268/70 Heading H4F When a television signal which has been frequency modulated on a carrier and recorded on magnetic tape is reproduced it contains unwanted components caused, e.g., by imprecision in electrical and mechanical components and vibration of the tape. In the systems described at least a part of the F.M. signal, for example the synchronizing components with or without a luminance signal, or an entire N.T.S.C. colour signal, is corrected before frequency demodulation using a reference signal which is recorded simultaneously with the television signal and may be, e.g., an added, continuous, reference frequency, Fig. 6 (not shown), or a periodically recurring part of the television signal such as the horizontal sync. signal or the colour burst, which is subsequently used to generate a continuous reference, Figs. 3 and 4 (not shown). The continuous reference signal, derived in Fig. 5 from the colour burst of the F.M. demodulated signal by circuits 19-21, is multiplied, 22, so that its frequency lies at or close to the F.M. carrier frequency, is combined additively or subtractively at 23 with a fixed frequency signal from 24, and the output is combined additively or subtractively at 25 with the F.M. modulated signal from the tape head 15. The resulting signal may be demodulated, 27, and used to provide the entire television signal if the unwanted components are small. If they are not small, the luminance and sync. components are passed by a filter 28 and combined at 30 with a chrominance signal which has been corrected at 32 in a known manner such as that disclosed in Specification 902,982. In Fig. 7 (not shown) only the sync. signal is corrected and passed to the mixer 30 (42) where it is combined with the uncorrected output of the demodulator 18 after the sync. component has been removed therefrom. The same oscillator may be employed in conjunction with different frequency multipliers to provide both the continuous recorded reference signal and the fixed frequency signal supplied to modulator 23, Fig. 6 (not shown).

Title: Improvements in or relating to synthetic lubricants
IPC: C07C69/34
Filed: 1952-09-29
Abstract: Synthetic lubricants comprise esters of the general formula <FORM:0716086/IV (b)/1> in which R and R1 are alkyl radicals having from 3 to 9 carbon atoms in a straight chain and n is a number from 1 to 6. The glycols from which the esters are derived may be prepared by reacting propylene glycol with propylene oxide.  The mixture of polypropylene glycols obtained is fractionated to yield the glycols in which n varies from 1 to 6.  The glycols are esterified by reacting them with acids containing from 4 to 10 carbon atoms per molecule.  In an example dipropylene glycol is esterified with n-octanoic acid using toluene as a solvent in the presence of sodium bisulphate.  Other esters referred to are tripropylene glycol di-n-octanoate and tripropylene glycol dicaproate.ALSO:Synthetic lubricants comprise an ester of the formula <FORM:0716086/III/1> in which R and R1 are alkyl radicals having from 3 to 9 carbon atoms in a straight chain and n is a number from 1 to 6 Examples of these esters are the di-n-octanoic acid ester of dipropylene glycol and the di-caproic and di-n-octanoic acid esters of tripropylene glycol.  The esters may be blended with other lubricating oils such as mineral oils or other synthetic lubricants or with viscosity index improvers, pour point depressors, oxidation inhibitors, rust inhibitors or corrosion resisting agents.

Title: Improvements in or relating to the production of sulfur dioxide
IPC: C01B17/56
Filed: 1949-09-26
Abstract: <PICT:0665007/III/1> Sulphur dioxide produced by burning sulphur-containing material, is freed from sulphur, oxygen and sulphur trioxide impurities by passing the impure sulphur dioxide through a purification zone containing a mixture of two finely divided metalliferous solids one being in a lower state of oxidation, for example Fe3O4, capable of oxidation by oxygen or sulphur trioxide impurities and subsequent reduction by sulphur, the other being in a higher state of oxidation, such as Fe2O3, capable of reduction by sulphur and subsequent oxidation by oxygen and sulphur trioxide, each solid being maintained in an amount of at least 10 per cent by weight of the total solids by the control of the oxygen and/or sulphur-containing material to the burner.  Systems other than Fe3O4-Fe2O3 which is preferred, are CuO-Cu2O, CuO-Cu, MnO2-MnO, MnO2-Mn3O4 and Fe2O3-Cu2O.  A fluidized solid bed is preferably employed as shown in the Figure where sulphur and air are fed to a burner 1 from inlets 2 and 3 respectively, the impure sulphur dioxide, together with additional air from 15 passing through a secondary combustion zone 5 and heat interchanger 17 to the purification zone 7.  The latter contains a bed 8 of a 50/50 mixture of Fe2O3, Fe3O4 maintained at a temperature of 700-1000 DEG C.  The purified sulphur dioxide is removed at 10, or, if it is desired to make bisulphites, the gas may be withdrawn at 11 and bubbled through a solution of sodium carbonate or calcium carbonate entering an absorption zone 12 at point 13.  The amount of air or p  oxygen fed to the combustion zone is adjusted, automatically if desired, in accordance with the state of oxidation of the purification zone, which may be determined (1) by sampling the gases which have passed through the purification zone, (2) by measuring the magnetic strength of the oxides in the zone, (3) by withdrawing a portion of the oxides from the zone to a separate vessel, passing air through under suitable conditions and measuring the exothermic effect of the oxidation, or (4) measuring the increase in temperature of the gas passing through the zone.

Filed: 1977-06-14
Abstract: 1529175 Transistor circuits ITT INDUSTRIES Inc 14 June 1977 [18 June 1976] 24719/77 Heading H3T A bipolar monolithic integrated push pull power output stage for digital signals substantially as shown has first 1 and second 2 transistors of the same polarity in series between supply U B  and earth with their emitter-collector paths joined by an amplifying device 3, also of the same polarity, having multiple emitters 31, 32; one 31 being connected both to the collector of transistor 2 and to the base of transistor 1. The bases of 2 and 3 are separately connected to the supply either by resistors or by constant current sources 6, 7. When transistor 2 is turned off the multiemitter transistor acts in the inverse sense with 31 as collector and 33 as emitter and tends to take the base current away from transistor 1. To prevent this the two emitters are dimensioned so that the area of the second 32 is at least twice, preferably four to five times, the area of the first 31. This gives an inverse current of about 0-1 and reduces the current bypassing. It is stated that the amplifier could be used to amplify linear signals such as those in audio amplifiers.

Title: Improvements in or relating to control means for the stop-motions of multi-spindle textile winding machines
IPC: B65H63/00
Filed: 1954-08-25
Abstract: 761,302. Stop motion control means. UNIVERSAL WINDING CO. Aug. 25, 1954 [Sept. 4, 1953], No. 24756/54. Class 120 (2). An apparatus for winding yarn comprises a plurality of winding units with common electrical means for driving the units, a stopmotion for each unit, actuating means for all of said stop motions, means normally operative to connect said driving means to said actuating means and means operative upon an interruption in electrical power to the driving means to disconnect said last mentioned means to render the stopmotions inoperative upon power failure in the machine. As shown the invention is applied to a winding machine having stop-motions substantially as described in Specification 745,490 in which breakage of a yarn y allows a breakage lever 15 to pivot, thus causing the engagement of the hooked pawl 25 with the oscillating rocker-element 27 so as to raise the bobbin-hanger 7 and lift the bobbin or spool off the driving drum 6. When the machine is operating normally, solenoid 55 is energized by current in the circuit to the driving motor of the machine and the armature 60 is held down. The pin 53 is engaged in the detent notch 70 in the side of slot 54 at the top of link 52. The arm 49 to which the pin 53 is attached is thus held down to maintain intermediate gear 45 in mesh with gear 40 all as shown in Fig. 2. In this position the gear 40 is driven from the drum-shaft 5 to cause the crank 37 to continuously oscillate the rock-shaft 30 and thereby the rocker element 27 so as to actuate the stop motion at any unit should the yarn there break. When, however, the machine is switched off or the current supply fails the solenoid 55 is de-energized to cause it to release the armature 60. The spring 65 moves link 52 upwardly and the pin 53 rocks the arm 49 to disengage the intermediate gear 45 from the gear 40 and thereby disconnect the oscillation of the rocker-element 27. The machine may be restarted without rendering the stopmotion mechanism operative until after the slack in the yarns has been taken up. The stop motion mechanism is made operative by movement of handle 50 to re-engage the gear 45 with gear 40.
