Title: Communication system for transferring information between a vehicle and a ground control station
IPC: B61L27/00
Filed: 1973-03-19
Abstract: 1374228 Selective signalling BENDIXCORP 19 March 1973 [3 April 1972] 13069/73 Heading G4H In a communication system for transferring information between a vehicle and a ground control station, a coded series of first and second frequencies is transmitted and in a receiver is fed to a phase-looked loop, the control feedback voltage in the loop thereby comprising the corresponding voltage-level-coded message. As disclosed, a 4-bit message, followed by its complement, represents sensor data (e.g. speed, door opened) from a vehicle, and is transmitted from the vehicle as a series of two frequencies, each pair of adjacent bits being separated by a third frequency, to one of a number of loop aerials spaced along the route. Each loop aerial feeds a respective phase-locked loop in which the aerial output, amplified, is compared in a phase-comparator with the output of a voltage-controlled oscillator to produce a voltage level which via a low-pass filter and a limiter controls the oscillator, the filter also providing the voltage-level-coded data signal. The latter is converted from 3-level to 2-level form, provided a threshold device responsive to the input of the phase-locked loop indicates the presence of signal, and feeds a shift register. When the shift register (8 bits) is full, as indicated by a counter, gates comparing the message and its complement for error are enabled to pass the message to a computer input register in the absence of error. The computer sends control signals to the vehicle via a selected aerial along the route. In the vehicle, a phaselocked loop as above is provided in the receiver.

Title: Improvements in knitting darning machines
IPC: D04B17/00
Filed: 1937-05-10
Abstract: 492,112. Darning-machines. OBERMAYR, P. May 10, 1937, No. 13262. Convention date, May 22, 1936. [Class 112] A machine for repairing knitted ware is constructed after the manner of a chain-stitching machine. The machine operates as follows : with the needle 48 in raised position, the recess 45 of the disc 44, which rotates on the main shaft 2, is caused to register with the locking slide 42, Figs. 1a and 14. The slide is pressed inwards and rotated to the slot in the ring 41 by the hood 46 on the looper plate 10, so that the slide springs into the slot. This brings the looper 6, Fig. 1a, into operative position and secures it against rotation. The stocking or like article to be darned is placed on the work support 12 and the needle 48 turned so that the thread lies on the side facing the looper 6. The needle is given its downwards stroke and the looper 6 seizes the loop, Fig. 5. On the upwards stroke of the needle, one of the series of loopretainers 5 takes the loop from the looper 6, as the looper returns to loop-seizing position, and holds the loop. The work drum 12 is moved one retainer interval during the up-stroke of the needle by the gears 18, 20, 25 and rack 14, to position the work so that the next loop is placed on the adjacent retainer, till a ring of loops is formed. The needle is then passed successively through these loops, forming new loops, which then receive the needle, till the hole in the fabric is filled. The needle is rotated half a turn before making the binding-off seam. The width of the work is varied by adjusting the pin 29 in a vertical slot in the plate 30 so that it trips the feed reversing pawl earlier or later, by the aid of the spring 37, according to its distance from the centre of the disc 30.

Title: Improvements in ratchet mechanism drives
IPC: A23G3/02
Filed: 1929-04-30
Abstract: 310,813. Anciens Etablissements A. Savy, Jeanjean, et Cie Soc. Anon., Baker Perkins, Ltd., and Hertz, S. April 30, 1928, [Convention date]. Depositing-machines. - Means for advancing mould trays in machines for depositing confectionery, &c. comprises ratchet gearing in which a pawl drives at predetermined intervals under the control of an independently rotated mask. In Figs. 4, 6, 7, ordinary ratchet gearing normally feeds starch, &c. trays in which rows of moulds have been impressed to the depositor, carrying them forward step-by-step distances equal to that between successive rows in a tray, whilst supplementary ratchet gearing comes into action to bridge the gap between the last row on one tray and the first row on that following. Hooks or stops are simultaneously raised to position the tray when the first row is brought beneath the depositing nozzles. The trays 1 pass from a conveyer 2 to a chain conveyer 6 by which they are brought beneath a row of nozzles 5<a> of a pump 5 supplied from a hopper 4. The conveyer chains 6 are driven by gears on a shaft 10 to which step-by-step rotation is normally imparted by a pawl 17 on a lever (not seen) operated through a rod 19 by a main lever 14 rocked through a link 13 by a crank 12 on the driving shaft 11 by which the pump 5 is also controlled. The supplementary drive bridging the gap between rows in successive trays is effected by the rocking lever 14 through a second rod 25 connected to an arm 24 loosely mounted on a lay shaft 29. The arm 24 carries a pawl 23, Fig. 6, adapted to drive a ratchet wheel 22 fast on a sleeve 28 loose on the shaft and geared by a pinion 30 to the shaft 10. Engagement of the pawl is controlled by a mask 31 secured to the shaft 29 which is driven through a worm wheel 34, embodying lost-motion means comprising a pin 35 engaging an arcuate slot in a wheel 36 by a shaft 3 which is intergeared with the conveyer 2. Thus, when a notch 32, Fig. 7, in the mask allows engagement of the pawl 23, the supplementary drive is imparted to the shaft 10 and thence to the conveyer, the lost-motion means allowing the shaft 29 and mask to be carried forward by the pawl. A detent 39 engaging the wheel 36 prevents reverse rotation. Stops 41, Fig. 7, for positioning the trays, are simultaneously raised, being connected through a rod 44, bell crank 45, 47 and link 48 to a disc 49 loosely mounted between the mask 31 and ratchet wheel 22 and formed with a peripheral notch adapted to be engaged by the pawl 23 when this engages the ratchet wheel 22. The disc 49 is brought back to its initial position, withdrawing the stops 41, by a compression spring 50 between a fixed element 51 and a collar 52 on a rod 53 connected to the bell crank 45, 47. The rod 44 acts on the stops 41 through a spring 56. Arcuate slots 21, 27 enable both the primary and supplementary ratchet strokes to be adjusted.

Abstract: 570,502. Valve relay circuits. BRITISH THOMSON-HOUSTON CO., Ltd., and TITLEY, C. O. Aug. 24, 1943, No. 13808. [Class 40 (v)] [Also in Groups XXVII and XXXVI] An arrangement for the control and testing of high potential electrical equipment such as ignition apparatus for' internal-combustion engines, comprises a circuit containing a gasfilled tube such as neon tube, mounted in proximity to the source of high potential so that the gas becomes ionized and renders the lamp conductive and thus varies the grid bias of a grid-controlled discharge tube and so energizes a circuit containing a relay, contacts of which effect the control or energize a measuring instrument. Fig. 1 shows a neon tube N associated with an amplifier T operating a relay R. The speed of operation is governed by the resistance capacity network R, C. A number of neon lamps connected in series may be used to control a number of circuits, Fig. 2 (not shown). In this-arrangement, failure of any one circuit will result in operation of the relay. Fig. 3 shows a modification in which a number of separate neon lamps N1, N2, N3 are used, each associated with an amplifier T1, T2, T3, but controlling a common relay R. A trigger action may be obtained by the use of a gas-filled triode in place of the high vacuum valve, Fig. 1 (not shown). Measurement may be effected by replacing the relay by a milliammeter and calibrating the gap between the neon lamp and an adjustable electrode connected to the source of the potential.

[Class 7 (v)] In a starting device comprising a valve 4 opened by pressure of the starting-air admitted at 25, when allowed to do so by a plunger 8 actuated by cam mechanism 10, 14, 16, 40 as described in the parent Specification, the valve-closing spring 29 acts on a washer 33 inserted under a head 28 on the valve stem. The starting-air first raises the plunger 8 so as to move the tappet 40 downwards into contact with the cam 16, compressing a weak spring 41. The valve 4 is then opened by the air pressure only as the plunger 8 is depressed by the cam mechanism, so as to move projections 7 on the plunger downwards from engagement with the waher 33. The washer is inserted over a squared part 19 of the valve stem by means of a radial slot 34, Fig. 3, in the washer, which is further provided with grooves 35 which, together with the slot 34, allow the plunger 8, with four projections 7, to be pushed across the washer. The plunger is then rotated through 45 degrees to bring the projections 7 under the parts 33a of the washer between the grooves 35. Rotation of the plunger is then prevented by engagement of lugs 36 at its upper end with the rocker 10, and rotation of the valve is prevented by a set screw 37 engaging a recess 38 in a collar 5.
