Patent GB-608988-A (GB)
Abstract: 608,988. Typewriters &c. ALLEN-WALES ADDING MACHINE CORPORATION March 4, 1946, No. 6641. Convention date, April 3, 1945. (Class 100(iv)] [Also in Group XIX] A calculating-machine comprises keys or the like for effecting fractional entries and either a dial or type support which is set under the control of the keys and in each position of which an odd- and an evennumerator character are in display or printing position, a shutter or a pair of printing hammers being controlled by the keys so as to select for display or printing one only of the positioned pair of characters. The machine (see Group XIX) includes a keyboard, Fig. 9, which, in addition to the usual columns of keys for entering whole numbers, includes two columns of keys 32 and 31 for entering odd- and even-numerator fractions, shown as sixteenths, respectively. Each even-numerator key carries a plate 33 which extends beneath the adjacent odd-numerator key in such a manner that depression of the latter also results in depression of the former so that, whichever fraction key is depressed, a stop bar 113, Fig. 2, will be controlled to position a lever 116 and a type bar 196, Fig. 3, which carries two sets of type for odd- and evennumerators, respectively. When .an even-numerator fraction is entered, an arm 201 is rocked to enable it, when moved forwardly by a mechanism, not shown, to release a latch 203 for :a printing hammer 198 associated with the even-numerator set of type. Depression of an odd-numerator key permits .a movement of a stop bar 120, Fig. 6, which operates through a lever 206 to raise a bar 207 carrying a plate 218 and a pin 219 on this plate then prevents rocking of the arm 201 so that the latch 203 for the hammer 198 is not released. A stud 214 on the bar 207 at the same time permits an arm 209 to rock so that, when the arm is carried forwardly, the latch for the hammer 199 is released and the odd-numerator is printed. A type bar 1611, Fig. 1, bearing a single set of type is provided for each of the whole-number denominations and a hammer 168, latch 170 and arm 176 co-operate with each type bar in a manner similar to that described above for the even-numerators of the fractions denomination. A zero movement of a type bar is insufficient to allow its arm 176 to trip the corresponding latch 170 for the printing hammer 168 but each latch has a flange 188 which projects behind the latch of the next higher order so that if a latch is tripped all latches in lower denominations will also be tripped to print zeros where the type bars have only made zero movements.

IPC: H02H7/127
Abstract: 666,985. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 6, 1948. [Oct. 8, 1947] No. 26064/48. Class 38 (v). [Also in Group XXXV] A protective system for a circuit comprising a number of current paths with each of which is associated a first relay operated by a condition of that current path, has a common time delay relay operated by all the first relays, and a time element relay which is operated by the common relay when this has been maintained in operation by one or more of the first relays for a predetermined time. A D.C. circuit 2, 2 is supplied from three phase circuit 1 through a rectifier comprising six ignitrons of which two 7, 8 are shown. The ignitors are energized through an impulsing circuit which includes a saturable reactor 19 and is fed from supply 1 through phase changer 17. At each ignitor impulse, arcs are struck between cathode 10 and main anode 9 and auxiliary anode 12 which is fed from an auxiliary transformer 35 through resistor 36. The voltage across resistor 36 energizes coil 42 of relay 38 of which there is one to each.ignitron, contacts 45, 46 open and contacts 44 close to energize signal 49 whereby correct operation is indicated. If the ignition of a valve fails the voltage across resistor 36 vanishes, relay 38 is de-energized, contacts 44 open and contacts 46, 45 close, respectively to cut out resistance 47 and to energize winding 54 of a second relay 40 through rectifier 52 and resistor 53 at a rate determined by condenser 51 and resistor 55. The closure of contacts 56 of relay 40 energizes a time delay relay 41 of the induction disc type. After a single misfire, relay 40 may remain closed for as many as 15 cycles, though it is not energized long enough to operate, but if there is a series of misfires in one or several ignitions, relay 40 being common remains closed and relay 41 energized long enough for contacts 60, 63 to close, when alarm 64 is sounded and main C.B. 72 is tripped to interrupt the supply to the main anodes.

Abstract: 727,160. Indicators on aircraft. SVENSKA AEROPLAN AKTIEBOLAGET. June 3, 1952 [June 7, 1951], No. 13936/52. Class 4. [Also in Groups XXXVI and XXXVIII] An aircraft instrument comprises a cathode-ray tube displaying' a luminous radial line and a circle the angular position of the line indicating the heading of the aircraft and the radius of the circle indicating the residual flying range at a particular air speed as determined by the available fuel, the altitude and the air temperature. As shown the output from a high-frequency oscillator 11 is rectified at 24 and modulated in phase quadrature in mixers 8 and 9 by the sinusoidal outputs from a low-frequency oscillator 7, the outputs from mixers 8 and 9 being applied to orthogonal deflection coils 2, 3 of the cathode-ray tube 1 to produce a rotating radial trace. An output from the low-frequency oscillator 7 is also applied through a goniometer phase shifter 12 controlled by a gyro 5 to a pulse generator 16 whose output is applied to the grid circuit 17 of the tube to momentarily intensify the trace once per revolution so that the angular position of the intensified trace indicates the heading angle. The half wave rectified high-frequency oscillations from rectifier 24 are also applied via a variable phase shifter 18 to control the pulse generator 16 so that the radial position of the intensified trace can be adjusted. The luminous circle is produced by applying the output from rectifier 24 to a second pulse generator 23, the timing of the output pulses being controlled by a computer 19 responsive to the electrical outputs from an altimeter 21, fuel gauge 20 and thermometer 22, a calibrated manual control being provided to compensate for the effects of head wind. A further control may be provided which modifies the radius of the circle to indicate the flying range at some other altitude, said control comprising two adjustments for setting in the selected altitude and the atmospheric temperature gradient. A map may be superimposed on the screen of the cathode-ray tube so that the position of the aircraft is indicated by the centre spot of the tube.

Patent GB-787196-A (GB)
Abstract: 787,196. Intercommunication systems. RIVA, A. DA. April 5, 1955 [April 6, 1954], No. 9939/55. Class 40 (4). In an intercommunication system in which any one of at least three stations can call any other station, each station has two controlling relays M and R and has sets of calling contacts T, each set corresponding to another station, and when operated actuating the relay M of the station being called and isolating the relay R at its own station. Each relay M is energized in series with a master relay Mx which when once energized prevents operation of any further relay M and gives privacy to the calling and the called stations. When energized relay Mx also energizes the relays R at all stations other than that of the calling station which is isolated by its calling contact T. A calling station has neither relay M nor R energized, a called station has both energized, while an idle station has only relay R energized. Each station has a key V which is brought into circuit by a relay M and can operate a relay Rx to reverse the connections to transmit-receive loud-speakers A utilizing a common amplifier Am. As illustrated a station I calls a station III by actuation of contacts T3 energizing relay M3 in series with Mx. Contacts Q1, Q2 of Mx energize relays R2 and R3; contacts Q5, Q6, isolate relays M1 and M2; while contacts Q3, Q4, switch H.T. to amplifier Am. With R1 energized and M1 not energized loud-speaker A1 is connected to the input of Am over relay Rx. With R3 and M3 energized loud-speaker A3 is connected to the output of Am over relay Rx, and R3 connects key V at station III in series with the coil of Rx. When made, key V actuates Rx and reverses loud-speakers A1, A3, between input and output of Am. A lamp S2 at Station I indicates that a talking connection is made to the called station and when the talk/listen key V is operated the lamp is extinguished. At all stations a lamp S1 indicates when the system is busy. At station II, with M2 unoperated and R2 operated, loud-speaker A2 is isolated and the calling contacts T1-T3 are impotent. The amplifier Am and the relay Mx are preferably located at a central exchange.

Title: Apparatus for aerating water e.g. in a fish tank
IPC: A01K63/04
Filed: 1979-09-19
Abstract: An inverted tray 6 is disposed in the bottom of a tank 2 to define an aeration chamber therein. Air is supplied to this chamber by a pump 12 so that a pocket of air is formed in the upper part 8a of the chamber and aeration takes place at the interface between the air pocket and the water in the chamber. An outlet pipe 18 leads from a position below the upper extremity of the chamber to a position within the tank and is arranged so that, as the pump supplies air to the chamber, the pocket of air forces the water in the chamber downwardly to a level at which air from the pocket may enter the outlet pipe and move upwardly therethrough in the form of bubbles. These bubbles force water in the pipe to move upwardly, and thus further water may be drawn into the chamber via openings in the side of the tray. The device may be used for contacting any gas with any liquid. <IMAGE>
