Title: Improvements in or relating to servo systems
IPC: G05D1/00
Filed: 1952-04-25
Abstract: 720,502. Automatic steering control systems. SPERRY CORPORATION. April 25, 1952 [April 27, 1952], No. 10441/52. Class 38 (4). In a control system for an aircraft having two elevons each operated by a servomotor, the elevons are moved in the same directions in response to a first control signal and in opposite directions in response to a second control signal, each servomotor driving a part of a feed-back generator supplying a signal in opposition to the first control signal and each servomotor driving a part of a feed-back generator supplying a signal in opposition to the second control signal. In Fig. 1 an A.C. signal dependent in magnitude and phase on the magnitude and sense of roll is derived from a pick-off 5 associated with a gyrovertical 3 and applied to a combined amplifier and demodulator 8 producing a D.C. signal of corresponding magnitude and polarity which is so applied to a network 16 that equal and opposite signals are applied through amplifiers 12 and 15 to operate electric or hydraulic servomotors 10 and 13 and move port and starboard elevons 1 and 2 in opposite directions to correct the roll. An A.C. signal derived from an A.C. source 7 by Selsyns 29 and 34 driven by motors 10 and 13, respectively, is then representative of the sum of the movements of the two elevons and is applied as a follow-up signal to the input of stage 8. Similarly an A.C. signal dependent in magnitude and phase on the magnitude and sense of pitch is derived from a pick-off 6 associated with gyro-vertical 3 and applied to an amplifier and demodulator 9 producing a D.C. signal of corresponding magnitude and polarity which is so applied to network 16 that equal signals are applied through amplifiers 12 and 15 to operate motors 10 and 13 and move elevons 1 and 2 in the same direction to correct pitch. An A.C. signal derived from A.C. source 7 by Selsyns 36 and 40 driven by motors 10 and 13 is then representative of the sum of the movements of the two elevons and is applied as a follow-up signal to the input of stage 9. Upon roll or pitch signals produced by Selsyns 36, 40 or Selsyns 29, 34, respectively, correct unequal movement of the elevons. In a modification, Fig. 5 (not shown), each servomotor drives, in the appropriate direction, the rotor of one Selsyn and the stator of another so that only two Selsyns are required.

Title: Apparatus for producing paper cylinders for nursing of seedlings
IPC: A01G9/00
Filed: 1973-03-05
Abstract: 1420775 Making seedling containers NIPPON TENSAI SEITO KK 5 March 1973 [4 March 1972] 10464/73 Heading A1E [Also in Division B8] A machine for making assemblies of hexagonal section paper cylinders for growing seedlings is supplied with a pre-formed tape A consisting of two rows of flattened tubes A1, A2 overlapped by one third of their width and glued together, the tape being fed between a pasting roller 4 and a counter-roller by a driving roll 13 cooperating with a counterroll, the tape then passing to a cutting roll 15 severing the tape into unit lengths. The unit lengths are fed by belts 19, and a belt 22 having spaced abutments 23 is driven more slowly than the belts 19 so that each length of the tape is held behind an abutment 23 and is supplied at the correct spacing to notches in teeth 25 of presser wheels 24. The presser wheels deposit the lengths in an upright position on a support 27, the outside of the teeth pressing the previously deposited lengths against each other to bond them into a unitary assembly. At predetermined intervals a length of tape is either unpasted or has a slip of paper covering the paste to separate the assemblies. In order to avoid pasting a length of tape, the pasting roller 4 is fast with a gear wheel 9 and a cam, the gear 9 meshing a gear which is mounted on the shaft of the counter-roller and is fast with a second cam cooperating with the first cam to raise the pasting roller at predetermined intervals. In the alternative arrangement in which a slip of paper is stuck to a length of tape, a roll 31 withdraws a slip 29 from a magazine 30 when a photo-electric means detects the absence of a slip on a delivery plate 33, the slip being delivered to the plate 33 by feed rolls 32. A wheel 39 is then rotated to bring a holding pawl 38 to a position B, a gate 37 opened to allow the slip 29 to fall onto a raised portion of the wheel 39, and the pawl 38 then released by a cam 43 to grip the slip. The wheel stops rotating when pawl 38 reaches a point C. When the cutting roll 15 has rotated a set number of times, an electromagnetic clutch is engaged and wheel 39 driven at the same speed as the tape A. When the slip 29 reaches the tape the pawl 38 is opened by the cam 43 and the slip is applied to the tape. Specification 992856 is referred to.

Abstract: 747,186. Cleaning sparking plugs. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 19, 1954 [April 20, 1953], No. 10728/53 Class 7(4) In method of cleaning a sparking plug of deposits formed during use, a cleaning liquid, comprising a solvent for at least one constituent of the deposits, is caused to impinge upon the latter in the form of a jet and to swirl with respect to the plug so as to exert a mechanical as well as a dissolving effect upon the deposits; the inventin also relates to apparatus for carrying out the method of cleaning. GENERAL ARRANGEMENT. A casing comprises two cabinets 1a and 1b, Fig. 2, which are bolted together, the shorter front cabinet 1a containing the cleaning liquid such as a 13.5 per cent weight/volume solution of ammonium acetate in water; caustic alkalis e.g. sodium hydroxide, or salts of organic acids, e.g. ammonium oxalate may also be used. Above the level L of the liquid is a filter 25 through which the liquid' drains from the sparking plugs, and adjacent the top of the cabinet 1a is a system of nozzles 3 which are arranged below a detachable tray 4 that accommodates the sparking plugs. The rear cabinet 1b houses a motor, not shown, coupled to a pump 5 which draws the liquid from the front cabinet and delivers it to the nozzles 3 via a manifold 15. Below the level of the liquid is disposed an electric heater 21. which under the control of a thermostat 23, maintains the liquid at a temperature .of, say 80 ‹C. The front of the cabinet 1a is provided with a glass panel whilst the visible part of the front of the rear cabinet forms an instrument panel containing motor and heater switches and indicator lamps for the thermostat, pump and heater. By means of. handles 4a the tray may be lifted and inverted upon the top of the front cabinet to permit inspection of the plugs. In a modification the casing is a single unit divided by a partition into two compartments which serve the same purpose as previously described. The liquid may be steam or gas heated. ARRANGEMENTS OF PLUGS AND CLEANING-LIQUID NOZZLES. The tray 4, Fig. 3, supports thirty-six sparking plugs in four rows 12, each plug is in an aperture 13 fitted with a grommet 14 of acid proof and heat-resisting rubber or like material. The manifold 15 which extends across and near the underside of the tray embodies four nozzles whilst extending laterally from each side of the manifold are four pipes 17 each incorporation four nozzles. Each nozzle 3 lies in a plane XX. Fig. 2, which is inclined at 20 degrees to the vertical and is laterally and rearwardly offset from the centre lines of the sparking plugs; this disposition. is made possible since the tray and manifold are adjustable. In the modification, the liquid is supplied to a manifold at one side of the apparatus which feeds four laterally disposed pipes each incorporating nine nozzles, the four pipes being arranged in a plane which is at an angle to the horizontal.
