Patent GB-454497-A (GB)
Abstract: 454,497. Shooting-practise apparatus. RAYOLITE RIFLE RANGE CO., 120, South La Salle Street, Chicago, U.S.A. March 29,1935, No. 9832. Convention date, April 12, 1934. [Class 119] [See also Group XL] Relates to imitation practise guns in in which a beam of light is thrown on a target when an electric circuit is closed by the pull of a trigger, and consists mainly in the provision of a ratchet device operated by the trigger to produce a temporary closure of the circuit. The lamp 20 is mounted on a sliding carriage 21 provided with contacts 26 normally held open by springs 24. A pawl 35 is pivoted on the trigger 13 and co-operates with a ratchet wheel 31 fast with a star wheel 32, which co-operates with a projection 34 on the lamp carriage 20, so that each time the trigger is pulled the carriage is pushed forward and allowed to spring back, whereby the lamp is flashed. The light from the lamp passes through a lens 27 and through the barrel 12 towards the target. The lens is adjustable along a screw thread 29 in the barrel. If the aim is correct, the beam of light passes through a lens 41 at the target and strikes a photoelectric cell 38 enclosed in a hood 39, the cell being adapted to make a record or give an indication of its operation.

The regions of the lateral transistor surround those of the normal transistor, the emitter region of which may be diffused through a meandering or combshaped masking layer 2<SP>1</SP>. Corresponding regions of the two transistors may, instead of being continuous with one another, be connected by conductors.

Abstract: 971,121. Co-ordinate conversion systems. SOC. NOUVELLE D'ELECTRONIQUE ET DE LA RADIO-INDUSTRIE. Dec. 21, 1961 [Dec.29, 1960], No. 45921/61. Heading G4G. In apparatus for converting the cartesian coordinates of a given point into polar co-ordinates with conversion errors reduced to a minimum, two resolvers 1 and 2 are mechanically coupled together so as to have the same electrical axes, and the first resolver 1 has its stator windings 4 and 5 fed with voltages proportional to the values of the cartesian co-ordinates X and Y to be connected. The resolver 1 delivers outputs from the windings 10 and 11 respectively where ° is the rotor angle. By positioning the rotor so that E; = 0, then °=#, the required polar angle and E 1  = D, the required distance vector. In order to achieve this position, the voltage E 1  = D + #D, #D being the error in D due to bad azimuth positioning of the resolver 1, is fed to an amplifier 12 which controls a servomotor 13. This operates to adjust the potentiometers 6 and 7, which are fed with the voltages X and Y so that they deliver voltages and X/D+#<SP>1</SP>D and Y/D+#<SP>1</SP>D which are supplied to the input stator windings 14, 15 of the resolver 2; #<SP>1</SP>D being the overall error in the distance D so far introduced. This resolver 2 delivers a voltage E<SP>1</SP> = D/D+#<SP>1</SP>D sin ## on the wind-   ing 16, where ## is the error in the polar angle #. That this occurs is shown mathematically in the Specification. This error voltage E<SP>1</SP> is fed to an amplifier 17 which controls a servomotor 18 so as to reduce this error to zero, within the limits of accuracy of the servo system. The required rotor distance D and polar angle # are then given by the output voltage of the first resolver and the angular position of the resolver axes respectively.

An input signal PV is compared with a set value PS by bellows 13, 14 to operate an input link 105 and a flapper 128 providing an automatic output from a nozzle 40 through a relay valve 22. The nozzle also provides a signal to a bellows 17 which opposes the signal Pi' in a bellows 41, providing feedback through a second link 125. When a switch 30, 31, 32 is operated to transfer the controller to automatic mode the feedback and hence the proportional band is changed by connecting the nozzle 40 to the bellows 41 through an integral throttle 33 and capacitor 34, the lever 110 thus being rotated about its upper pivot to vary its angular relationship with the input and feedback links. The pivots between the links and lever are formed by flexible strips and the construction is illustrated in greater detail in Fig.3 (not shown). Stops 134, 135 restrict the movement of the input link 105.

In use, tube 34 supplies a quantity of gas greater than that needed to prevent the liquid from flowing out of the receptacle outlet 20 such that the excess rises through the receptacle in the form of bubbles 40 and so causes mixing turbulence within the body of the liquid. When valve 38 is closed, liquid flowing out of the receptacle outlet 20 is subjected to the influence of an aerosol air supply 21. The switch arrangement 10 and the aerosol supply 21 in combination are usable in flame photometry.

The pontoon 5 is positioned between the quays 1, 2 with the edges of deck 4 spaced above the elements 6 and then it is ballasted by a pump 7 controlled by a control 11 which is responsive to pressure sensing elements 10 in the supports 6 until the load on the elements 10 reaches a first predetermined value. As construction on the deck 4 proceeds the load on the elements 6 will increase until a second predetermined value is reached to cause the elements 10 to actuate via control box 11 the pump 7 and deballast the pontoon until the load returns to the first value. This sequence continues until construction is complete at which time the pontoon is deballasted further under manual control until the undersides of the deck 4 disengage the element 6 so that the pontoon can be moved from between the quays 1, 2. A plurality of pumps 7 can alternatively be installed in the pontoon and controlled as above. The support elements 6 can be vertically adjustable, e.g. by means of a screw or hydraulic piston.

The three sections of the memory cyclically interchange their functions after each DSI control frame. At the receiver a channel allocation memory 58 has two sections, one holding channel allocation information transmitted during the previous DSI control frame, and indicating the line allocations of the channels received during the present frame, while the second section stores allocation information transmitted during the present frame for use during the following frame. The channel allocation information is transmitted as a series of "1"s or "0"s indicating active or pause state of the relevant line. The channel allocation information is time division multiplexed in with the digitally coded speech signal, one complete frame of the control information being interspersed between a number of complete frames of speech signal information, each frame having one sample of each DSI channel.
