Title: Improvements relating to retractable aircraft undercarriages
IPC: B64C25/20
Filed: 1933-11-15
Abstract: 428,539. Retractable undercarriages. HAWKER AIRCRAFT, Ltd., and CAMM, S., Canbury Park Road, Kingston-on-Thames. Nov. 15, 1933, No. 31867. [Class 4] In a retractable aircraft undercarriage having a plurality of points of application of operative force constrained to move at varying rates, a differential device, adapted to allow for the relative rate of movement between the points of application, is provided in the transmission means. In one form, a landing-wheel 5 is supported on resilient compression members 1 spaced apart to receive between them the wheel and pivoted to a supporting-frame 6 also pivoted to a lever 8 rigid with a double - grooved pulley 11. Retraction of the landing-gear is accomplished by winding a cable 25 onto a drum 26. The cable is connected through a spring 24 to a pulley 23 over which and pulleys 22, 29, 30, 31 passes a cable 21, 21B secured at one end to the rod 6 and at the other to the pulley 11. Initial tension rotates the drum 11 anticlockwise which, through frictional engagement, rotates a lever to disengage a catch 14 co-operating with a detent 16 having a slot 19 adapted to engage a pin 7A connecting the frame 6 and lever 8 for locking the landing-gear in its operative position. Continued winding forces the pulley 31 and lever 8 anticlockwise, rotates the pulley 11 and pulls on the frame 6; thus the joint 7 is freed and moves past the line joining the pivot of the pulley 11 and the wheel axle 4. During retraction the pulley 23 allows for the varying rates of movement of the pulley 11 and the point of attachment to the frame 6. The landing-gear is extended by rotation of a drum 27 integral with the drum 26 to wind up a cable 28 which has during the process of retraction been wound on the pulley 11. The cable 28 is secured to the pulley 11 or is made continuous with the cable 21B and secured to the pulley 11. The spring 24 allows for slight inequalities in the rate of paying out of cable 28 and hauling in of cable 25. The spring 24 may be omitted, in which case the drums 26, 27 are connected by a torsion spring. A brush for cleaning the landing-wheel is provided. In a modification, a lever 51 connected to the frame 6 and the shock-absorbers 1 are rotated for retraction or extension of the landing gear through gearing and toothed quadrants from a differential gear which is driven from a sprocket wheel 44, the quadrant on the lever 51 being driven from the differential through a chain 46 and a sprocket 47. The frame 6 is pivoted to a member 53 slidable in a bearing in the lever and provided with a rubber buffer 54 which bears, when the landing-gear is operative, in a recess 55 in an anchorage secured to the rear wing spar. The wheels may project slightly when retracted.

Abstract: 892,430. Multiplying apparatus. ADREMA Ltd. Jan. 5, 1960 [Oct. 7, 1958], No. 31950/58. Class 106 (1). An electronic digital multiplier comprises a memory device such as a magnetic drum in which predetermined multiples of the multiplicand may be recorded to be gated out by a multiplier into an accumulator to form the product. Fig. 1 shows the surface of a drum used for calculating shareholders dividends or rate demands by multiplying a dividend, or a " rate in the pound," recorded in track 13, by a multiplier obtained from a record card and representing the number of share units held or rateable value. The drum has signals permanently recorded in tracks 1-9 in the positions and with the significance shown, and in the " setting-up " procedure these are read out by heads RH1-RH9, and gated according to the partial products successively entered in a keyboard (Fig. 3, not shown) to record a sterling (rate) amount in track 13 (the amount 2/ 10d. is shown recorded there) and multiples as shown if it in tracks 14-32, a manual switch being provided for selecting heads 13-32. The keybbard entry controls the gates by altering the recovery time of 9 mono-stable flip-flops which are set successively by signals from RH12 to open the gates associated with RH1-BH9 for appropriate periods. Fig. 2 shows the circuitry used for multiplication of the rate set up, by a multiplier entered in binary coded decimal form into flip-flops FF13-FF32 from a record carrier such as a printing plate carrying the name, address and rateable value of a ratepayer. On receipt of a start signal FF11 is set to open G11 and the start of revolution pulses from RH11 are fed to a scan unit which successively supplies signals to threshold 2 gates G13-G32 which if opened by FF13-FF32 pass the partial products from RH13-RH32 through amplifier A2 to gates G33-G40, to be accumulated in product accumulator PA. When twenty revolutions have been completed, all the gates G13-G32 enabled by the multiplier will have been opened and the final product accumulated; scan unit then resets FF11 and orders print-out of the product by print machine PM.

Abstract: 1339828 Mass spectrometers PERKINELMER CORP 13 July 1971 [13 July 1970] 32824/71 Heading H1D The sensitivity of a mass spectrometer is maintained constant by passing signals from ion collectors 22a, 22b, and 22c to an amplifier 30 where they are summed and compared with a reference signal from a transducer 31, and if the difference varies from a predetermined value, e.g. zero, an error signal is fed to a control 32 to vary the level of ionization of the gas in the ion source 10 by varying the emission of cathode 12. A gas mixture is passed through a sample inlet 16, e.g. a molecular leak, to the chamber 10 where it is ionized by an electron beam 11 between cathode 12 and anode 13. The resulting ions are accelerated through an aperture 17 into analysing chamber 18 by a lens 19 and are deflected by magnetic field 20 to collector cups 22a, 22b and 22c connected to electrometers 23a, 23b and 23c which amplify the collector currents and apply them to signal indicators 24a, 24b and 24c which may be calibrated to show the proportional amounts of particular gases. The outputs from the electrometers 23a, 23b and 23c and a reference voltage from total pressure transducer 31 are fed through resistors R1, R2, R3 and R4 to amplifier 30. Alternatively, the reference voltage may be supplied by an independent voltage source (Fig. 2, not shown). Feedback resistors R5a, R5b and R5c are connected across the electrometers 23a, 23b and 23c to ensure maximum electrometer outputs consistent with the operating range of the instrument. Alternative means for varying the ionization level in accordance with an error signal comprise: applying the error signal to vary a resistance connected to anode 13; varying the potential of the lens 19; utilizing a split electrode in place of the lens 19 to deflect ions from the aperture 17; utilizing a repeller electrode to adjust the flow of ions from chamber 10; and providing control grids in the path of the electron beam 11. Alternative ionizing arrangements comprise a cold cathode emitter, a point source of high voltage, and ultra-violet light.
