Title: Improvements in means for tracking movable targets
IPC: G01S13/70
Filed: 1957-08-22
Abstract: 844,463. Target tracking apparatus. ARENCO A. B. Aug. 22, 1957 [Aug. 30, 1956], No. 26573/57. Class 97(2). [Also in Group XXXVI] A sighting device is positioned by servo-motors operating in a polar co-ordinate system, one motor being controlled in accordance with the equation : where sv is the azimuth co-ordinate and A the range. In the system shown the servo-motor 3 rotates the shaft 1 to position a radar or.optical sighting device in azimuth. Tachometer generators 4 and 5 generate voltages of opposite sign multiplied in a potentiometer 7 rotated by the shaft 2, which turns in terms of A/A, to produce a voltage representing sv.A/A fed through a resistance 11 to a summator 43 where it is added to a voltage -#sv produced by the condenser 14. The motor 3, driven from an amplifier 12 fed from the summator, normally runs to balance these voltages, the circuit constants being chosen to satisfy the above equation. If this condition is not satisfied the motor speed, is corrected by utilizing voltage sv appearing in the amplifier output 18 to a condenser 13 to produce #sv which is fed to the summator 43. If the generator co-ordinate sv is not that required to follow the target a correction voltage is applied to the summator through resistance and condenser 32, 33 either from the radar at 37 or from a manually operated generator 35, according to the position of the relay 34. The potentiometers 21, 22 driven from the shaft 2 produce, on the lead 27, a voltage representing A<2>/A<2>. This voltage is added in the summator 20. to voltages representing the derivative of #A/#A, produced by the generator 29 on the shaft 2 and one representing sv<2> produced by the generators 5 and 6 to produce a voltage fed to the amplifier 31 driving the motor 26 which thereby rotates the shaft 2 in terms of A/A to satisfy the equation : If the generated range co-ordinate is not that required to follow the target a correction is applied from the radar at 41 or from the manually operated generator 39 according to the position of the relay 38. If purely manual following is required the relay 10 is actuated to disconnect the resistance 11 from the potentiometer 7 and connect it to earth. A control switch is provided to position the relays 10, 34, 38 according to the type of following required. The apparatus described deals only with movement in one, e.g. horizontal plane. A similar apparatus may deal with vertical movement for three dimensional tracking. A voltage representing sv may be fed to a ballistic corrector at 44 if needed.

Title: Equipment for continuous splicing of wooden slats

Filed: 1971-04-19
Abstract: 1342170 Joining wood end to end CENTRALNE BIURO KONSTRUKCYJNE PRZEMYSLU MASZYNOWEGO LESNICTWA 19 April 1971 [16 April 1970] 26730/71 Heading B5L A machine for joining end to end a series of wooden slats 28 whose ends are shaped to interfit with one another and the end surfaces of which are covered with layers of glue, comprises feeding and braking sections 2, 3 each composed of a lower conveyer, 4 or 5, and an upper conveyer, 6 or 7, between which slats are fed in succession, each two successive slats being urged together end-to-end when one of the slats is in each of the sections. An hydraulic unit is installed in each conveyer and is utilizable as an engine to drive it, the units of the braking section normally acting to drive the conveyers 5, 7 of that section more slowly than those of the feeding section. When, however, the trailing end of a slat in the braking section is engaged by the leading end of a slat in the feeding section, to form a joint, the force transmitted from the conveyers 4, 6 of the feeding section to those 5, 7 of the braking section via the slats causes the conveyers 5, 7 to drive the hydraulic units of that section so that they act as pumps. As described, the hydraulic units are included in drums 13 which drive chains 15 of the conveyers 4-7. The hydraulic units of each of the sections 2, 3 are arranged in parallel, and the pairs of units of the sections are arranged in series. The hydraulic circuit also includes servomotors 17 which are arranged to move frames 8 carrying the conveyers 6, 7 towards or away from the conveyers 4, 5. In operation, a slat 28 introduced into the apparatus operates a switch 26 which causes a pump to feed fluid to the hydraulic units. An auxiliary pump is also actuated to feed additional fluid to the units of the feeding section 2 so that the conveyers 4, 6 move more quickly than the conveyers 5, 7. Hence when the first slat 28 reaches the braking section 3 and a second slat is introduced which is urged longitudinally against the first slat, the clamping pressure between the slats causes the first slat to drive the chains 15 of the section 3. The units of this section now act to pump fluid to the servomotors 17 thus causing the conveyers to be urged together to exert a greater gripping force on the slats. In a second embodiment the auxiliary pump is omitted and the different speeds are produced by using units of different volumetric capacities. The units may drive the drums 13 via gearing. Cleaners 27 are provided for the chains 15.
