Title: Improvements in or relating to indicators for score values set up on game apparatus,and to dartboards for use therewith
IPC: F41J5/04
Filed: 1948-04-23
Abstract: 644,517. Counting-apparatus. ABBETT, D. F. April 23, 1948, No. 11219. [Class 106 (i)) [Also in Group XV] In a scoring device for games, units and tens values of the same numerical value are selectively entered by a single actuator member having a pair of independently-actuable motionimparting elements each co-operating with a units or tens indicator, the elements being actuated by power impulses of different strengths. The device may be used to sum the score in darts, a dart-board (Fig. 6) being divided into scoring areas T<SP>1</SP> &c., each of which is moved back when struck by a dart to make contacts to feed pulses of current to a counting device (Fig. 5) through wires I.C.1-9. A current pulse due to a units value passes through a resistance and is thus weaker than the pulse due to a tens value. For scores where the tens value equals the units value, two contacts are provided, being made successively to give one pulse for the tens and another for the units. The counting device comprises a frame 18 carrying nine solenoids 1 fed with the current from the dartboard. Each solenoid carries two armatures 2, 3 entering the tens and units respectively through ratchets 12, 13 on axles 20, 19 driving indicator drums 23, 22. Carry-over devices 30, 31 are provided from the units drum 22 to the tens drum 23 and from the latter to a hundreds drum 24. The motion of the ratchets 12, 13 is proportional to the value to be entered. As shown in Fig. 4, the tens armature 2 and the units armature 3 are loaded by springs 6, 7 respectively, the former being stronger than the latter. A weak pulse representing a units value can thus operate the units armature only. A strong pulse operates the tens armature which in its motion throws a trip 14 in the way of armature 3 to prevent the entering of a units value. When used for darts scoring the solenoids for the values 7, 8 and 9 carry only a units armature. The dart board may be made in sectors secured together.

Filed: 1972-03-10
Abstract: 1325833 Dual fuel engines; regulating SULZER BROS Ltd 10 March 1972 [10 March 1971] 11335/72 Heading F1B The power plant comprises a diesel engine (not shown) operating on liquid fuel and/or gas obtained by vapourization from a liquid gas tank, a compressor 130, liquid and gaseous fuel metering devices 111, 114 inter-connected by a differential device 107 so that when one delivery rate increases the other decreases, a servomotor 117 adjusting one device, the plant being arranged so that a gas pressure controller 138 maintains the compressor delivery pressure constant and a pressure detecting means 140 between the tank 127 and the compressor controls the servomotor in dependence on the pressure detected. The pressure in the compressor delivery pipe 132, leading by pipe 135 to the engine, is determined by a pressure controller 162 which actuates the servomotor 138<SP>1</SP> of valve 138, the controller 162 receiving its set value from comparator which is subject to air pressure in lines 175, 176. The pressure in line 175 is set by a pressure reducer 164 controlled by a cam 108 in dependence on the position of a set value output lever 103 from an engine-driven speed controller 101. The pressure in control line 176 is set by a pressure reducer 126 in dependence on the measured value of an engine delivery torque measuring element 122. The torque delivered by the engine during gaseous fuel operation always corresponds to the torque during liquid fuel operation for the same setting of output lever 103. If the gaseous fuel is of a constant calorific value the pressure reducers 126, 164 and comparator are omitted. Gas leaving the compressor 130 passes through a temperature controlled heater 133 and a smoothing tank 134 to the engine line 135. The top and bottom gas pressure limits in line 129 from the tank 127 are controlled by pneumatic pressure transducers 139, 140. Transducer 139 actuates valve 136 to open when a maximum pressure is exceeded. Transducer 140 is connected to a pressure reducer 143. The latter can also be actuated by an arm 145 from servomotor 138<SP>1</SP>. Lever 107 controls a pulse generating pump 114 which controls the engine gas inlet valves (not shown) and a fuel injection pump 111.

Abstract: 698,569. Electric follow-up systems. SANGAMO WESTON, Ltd. May 15, 1951 [May 15, 1950], No. 11358/51. Class 40 (i). In a follow-up system of the Selsyn or balanced bridge type of D.C. of magnitude and sign corresponding to the magnitude and sense of the error voltage is applied to a control relay, a contact of which selectively energizes one of two auxiliary relays to energize the servomotor in the appropriate sense, the control relay as it operates connecting an opposing anticipatory voltage into its operating circuit to prevent hunting. As shown in Fig. 1, the angular position of a control member P is transmitted through a Selsyn system to develop a positional error voltage in the receiver rotor R', which is applied through a series connected potentiometer 24 to a phase sense error detecting bridge 1, fed at 9 from the same A.C. source as that feeding the Selsyn transmitter. The detector output, through a control relay 6, actuates an auxiliary relay 15 or 15<SP>1</SP>, according to the sense of the positional error, to energize the split phase motor M to drive the load and the receiver rotor R' to follow up the control member P. The usual phase splitting condenser C is series connected with the potentiometer 24 whereby the voltage developed across the latter is always in phase opposition with the series connected error voltage and functions to anticipate changes in the motor energization and so prevent hunting. The magnitude of the anticipatory voltage is substantially constant but adjustable by means of the potentiometer. In a modification, Fig. 4, the anticipatory voltage is developed across one or other of individually adjustable resistors 26, 26', series connected with the receiver rotor R'. The relays 15, 15' controlling the direction of rotation of the servo-motor M as in Fig. 1 have further contacts b which connect the appropriate resistor 26 or 26' across the supply 19 to develop the anticipatory voltage. Fig. 5 shows the invention applied to a balanced D.C. bridge type of servofollow-up system where the potentiometer arm P' is driven by the motor M to follow movements of the transmitter potentiometer arm P. Here the anticipatory voltage, derived from a battery 34, is developed across one or other of resistors 32, 32', series connected with the relay 6 in the bridge output diagonal, and is applied in the same way as in the Fig. 4 embodiment. In a further embodiment, Fig. 6 (not shown) the anticipatory voltage, instead of being applied in series opposition to the error voltage, is applied to a separate winding of the relay 6 to produce a counter torque opposing that produced by the error voltage, and is derived from the same battery as that energizing the bridge.

Abstract: 128,626. Thornton-Pickard Co., Pickard, A. G., and Slinger, r. Aug. 15, 1917. Teaching small-arm shooting and gunnery.-A photographic camera is constructed so as to have an external contour and appearance as nearly as practicable the same as a Lewis or other machine gun, and so as to require all the movements necessary for machine gun operation to obtain a satisfactory photograph; practice with the camera is thus equivalent to gun drill or practice. As shown, the camera. resembles a Lewis gun, having a barrel A, a stock B, a trigger C, a trigger handle D, a handle E by which the gun is oscillated, and a pillar f to receive a magazine. The barrel contains a lens G, and a chamber H at the rear of the barrel contains a film K and film-winding means. When the magazine is placed in position, it depresses a rod n which rocks a lever N and operates a punch in a casing p to perforate the film. The sliding bolt M is connected by a chain K<1> to the barrel of a spring motor L, and when it is drawn back, it winds the spring of the motor, and also operates through a train of gearing k to wind the film forward ready for exposure. The bolt is held in its rear position by a catch c, andis provided with an arm g which, as it is drawn back, slides over a spring-controlled projection at the lower end of a lever g<2> mounted between its ends on a horizontal pivot. The upper end of the lever g<2> is connected by a cord g<1> to a betweenlens shutter. When the trigger C is operated, the bolt M is drawn forward by the motor L, and the arm g engages the lever g<2> and turns it so as to operate the shutter. A screen h with circles, cross-lines, or other markings may be placed in front of the film so that these markings are reproduced on the photograph to indicate the degree of accuracy of the shooting, and a counter R may be provided to register the number of exposures made. The film and winding means may be replaced by plates and plate-changing means, and an electric motor operated by a battery may be substituted for the spring motor, the movement of the bolts M then controlling the motor circuit.
