Title: Method of indicating a balance reading error
IPC: G01G23/32
Filed: 1973-05-24
Abstract: 1437272 Reading error detection AUGUST SAUTER GmbH 24 May 1973 [31 May 1972] 25027/73 Heading G1A A method of checking a balance reading comprises obtaining signals indicating both magnitude and direction of movement from at least one displacement encoder moved from a datum position under the action of a weight, feeding the signals into at least two counting channels, comparing the counts and producing an error signal when they differ. As described, the pulses are produced from the interaction of photo-cell F3, F4 with scale 3 and optionally also photo-cells F 1 , F 2  with the scale 4. The signals for the two counting channels are generated by logic circuits, e.g. 10 on Fig. 5, which detect the state and changes of state of the pairs of photocells. The pulse are fed on line V to count up counter 11, line R to count down counter 11 and similarly on another pair of lines to a second counter 12. The pulses to counter 11 also set a flip-flop 24 and a directing flip-flop 20. The count in counter 11 is normally increased before that in 12 so that a difference exists for a time. This difference produces on an output from comparator 13 which actuates monostable 17 and alters the count in counter 12 by 1 via one of directing gates 18, 19. This pulse also sets flip-flop 21 which is reset by the next counting pulse to counter 12 and prevents this pulse reaching the counter thus preventing incorrect reading. The comparator pulse also resets flip-flop 24 which was set by a counting pulse V or R to counter 11. While bi-stable 24 is set a fault output is passed to delay device VZ which gives an output only when its input exceeds a predetermined duration. It will therefore produce an output if either comparator 13 is faulty and does not reset bi-stable 24 or if the counts in 11 and 12 differ after the "correction pulse" from 17. A genuine error signal may be indicated by a lamp or modification of a digit in the output reading and a comparator may be provided in parallel with the first comparator as a check.

Title: Apparatus for delivering a load from an aircraft by parachute
IPC: B64D1/02
Filed: 1966-06-07
Abstract: 1,145,917. Parachutes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 7 June, 1966 [9 June, 1965], No. 25343/66. Heading B7G. [Also in Division H4] In the parachute delivery of goods, e.g. parcels, by means of a small stabilizing parachute, and a main or load parachute, part of the goods' descent is substantially free fall with only the stabilizing parachute open, and the load parachute is opened at a predetermined altitude, as determined by a radio altimeter, comprising an aerial 5 and supporting arm 1. The invention relates to the fact that before the parcel is ejected from the aircraft &c., the aerial and arm are locked in an unobtrusive position against the side of the parcel, and are only swung into an operative, horizontal position when the parcel is ejected. When the parcel is ejected, the stabilizing parachute immediately extends and pulls wire 10. This causes the removal of pin 11, thus activating the altimeter battery 6, and the removal of locking pin 7, from a hole in plate 8, connected to arm 1, and a tube 9, attached to base 4. Arm 1 and aerial 5 are thus released and are swung, under the action of spring 12, through 90 degrees into an active horizontal position. A spring-loaded block 13 moves under the turned, lower part of arm 1, and prevents movement of the arm from its active position. When the altimeter detects the predetermined altitude, an explosive device is activated, rupturing the ropes connecting the stabilizing parachute to the parcel. As the stabilizing parachute moves away from the parcel it pulls a cord which causes the opening of the load parachute.

A resinous homopolymer of methacrylonitrile or copolymer obtained by polymerizing a mixture of methacrylonitrile and methyl methacrylate containing at least 10 per cent by weight of methacrylonitrile based on the combined weights of the two monomers is mixed with a rubbery copolymer of butadiene-1,3, there being from 65 to 95 per cent of the resinous polymer in the composition based on the combined weights of the resinous and rubbery polymers. Rubbery copolymers specified are those of butadiene with less than its own weight of acrylonitrile, methacrylonitrile, styrene or methyl methacrylate. The polymer mixtures may be obtained by mixing aqueous dispersions of the two polymers and then removing the water; alternatively, one polymer in dry form may be added to an aqueous dispersion of the other polymer followed by removal of water, or both polymers in dry form may be mixed together by mastication. When the rubbery copolymer is prepared in latex form 2-alphamethylcyclohexyl-4: 6-dimethyl phenol may be added thereto prior to coagulation. The compositions obtained are vulcanizable and may be used for making pipes, pipe couplings, refrigerator parts, panels, helmets, wheels, gears, pulleys and combs.

During a single revolution of the main shaft 3 the carton is moved forward the distance of one cell row so that four tubes will fall through the opening 51 into the holders 24-27. During a second revolution of the shaft 3 the carton is not moved since the intermediate link 30 is retracted; but the lever 18 is pivoted clockwise by the cam disc 11 thereby expanding the linkage 22, Fig. 3 (not shown).
