Filed: 1966-08-04
Abstract: 1,101,219. Measuring altitude rate electrically. COLLINS RADIO CO. Aug. 4, 1966, No.35014/66. Heading G1N. In an aircraft control system a rate of change of altitude signal is produced at 11, Fig. 1, and supplied via a low-pass filter 14 to a mixer 16, and a vertical acceleration signal is produced at 18 and supplied via a band pass filter 25 to the mixer 16, the output of which represents the altitude rate. The uncorrected altitude rate signal from 11 is passed through a circuit 13 which removes unwanted quadrature components; and in the filter 14 are removed high frequency components arising from electrical and aerodynamic noise. The filter 14, however, removes true high frequency components of the signal and introduces some lag, and to counteract this the high frequency components are effectively reintroduced from the band pass filter 25. The band pass filter 25 removes from the acceleration signal from the accelerometer 18, low frequency components due to the earth's gravitational force, and other components due to various steady state errors in the accelerometer output. The output of the accelerometer 18 has added to it at 20 a signal from gyro-vertical transducer 21 supplied via a shaping circuit 22, to correct for errors arising from banking.

[Class 132 (iii).] Comprises a construction of hand-operated apparatus for moulding toy and other bricks and the like of the type in which a plunger is lowered into mould walls to compress the material and the moulded article is stripped by raising the movable frame comprising the mould walls bodily from the base-plate while the moulded article is held thereon by the pressing plunger. Figs. 1 and 2 show mould walls connected by links 34 to a shaft 31 carrying an operating lever 33 movable between the full and dotted line positions shown in Fig. 2. The stop 35 limits the movement of the operating lever in both directions. The pressing plunger 16 is connected by a bent lever 39 to a crank arm on the sleeve 37. Each linkage finishes in a " dead-centre " position at the end of each stroke of its operating lever so that the mould walls and plunger will remain in both the upper and lowered position when set therein. Fig. 4 shows an example of one liner or core 40 used in the mould to produce non-rectangular bricks. Several bricks may be moulded at once by the use of a zig-zag former, also the baseplate of the mould may be formed as a die to imprint a pattern or design on the moulded bricks.

Abstract: 619,916. Feeding webs. ERICSSON BROS., Ltd., and SIMPSON, A. W. Nov. 28. 1946,'No. 35318. [Class 100(i)] [Also in Croup XV] A device for feeding paper or the like from a manifolding or like machine is constructed with ratchet mechanism operated by a lever 11 for giving the feed rollers a predetermined movement at each actuation of the lever, and the operation of the device is controlled by a full-stroke mechanism. The lever 11 is attached to a shaft 12 fitted with a disc 13 having a spring-loaded pawl 17 adapted to engage successively in ratchet apertures 14b, 14c, 14d, . in a freely mounted annulus 14 fitted with a gear 14a in gear with a wheel 15 which drives feed wheels for feeding the paper. Prior to the action of the lever 11 in a clockwise direction a stop 18a on an arcuate member 18 secured to the disc 13 is held by a spring 31 in contact with a fixed abutment 19 secured to the casing 10 of the apparatus. The disc 13 rotates about 10 degrees before the pawl 17 engages the aperture 14b, and when the disc has rotated a further 120 degrees, the feeding operation is stopped by engagement of a pivoted catch 24 with a projection 15a on the wheel 15, the gear ratio of wheels 14a, 15 being three to one. The catch 24 is operated by engagement of an adjustable stud 21 with a block 23 on the catch. The movement of the lever 11 is finally arrested by engagement of stop 18b with the abutment 19. To ensure a full stroke the disc 13 is fitted with a ratchet. sector 27 engaged by a spring- pressed pivoted pawl 28, which prevents the return of the lever 11 until the last tooth of 27 has passed the pawl 28. In a modification, Fig. 4, in which the feed mechanism is arranged within the body of a machine as distinct from the form described, which may be an attachment to known machines, the lever 11 is formed integral with a gear sector 32 which meshes with a gear 15 fitted with a pivoted pawl 38 adapted to drive the shaft 16 of the delivery roller by engagement with a tooth 37. The sector 32 is normally maintained by a spring in contact with a stop 34, and the feed is actuated by moving lever 11 counterclockwise until the sector engages a stop 33. The shaft 16 is rotated one revolution and then held by a stop 24 as in the first modification. On reversal of the lever 11 the pawl 38 moves idly and finally passes over an inclined end of tooth 37 ready for a further operation. Reversal of shaft 16 is prevented by a stop 36 and gear 35.

The belts 6, which are mounted on pulleys 7, 8, pass between guides 9, 10 which conduct the belts from contiguous to spaced parallel paths beneath a drum 11 fitted with knives 12 to cut the strands into lengths. Paper 14 from a roll 13 is coated with adhesive by a roller 16 dipping into a bath 17 and passes thence between rollers 18 to shears 19, which cut the paper into lengths. The coated paper strips pass between rollers 20, 21 guided by a plate 22 on to a conveyer band 23, which carries the strips into a sleeve 26 which folds each strip around a length of material as it leaves the drum 11. The wrapped material 27 passes on to a conveyer band 28 moving more rapidly than bands 6, 23 so that the cartridges are separated in the longitudinal direction.
