Title: Statistical column graph forming apparatus
IPC: G09D1/00
Filed: 1947-08-06
Abstract: 631,045. Reel and web indicators. CORREA, E. Aug. 6, 1947, No. 21485. [Class 3(i)] An adjustable column type graph comprises a series of endless cords or belts on pulleys each having a marking along its length to indicate a column of the graph, a screen being provided for the effective run of each cord or belt so that by means of manually-operable mechanism selected columns are exposed to view. In a frame 1, Figs. 1 and 2, a number of endless cords 2 are mounted side-by-side on pulleys 3, 4 and rollers 5. The cords are of substantially circular cross-section and are moved lengthways by the mechanism shown in Fig. 3, which is slidably mounted on guides 20 on the frame 1 so that it may be positioned to engage the desired cord indicated by a pointer 22. The mechanism comprises a rubber roller 13 mounted in a frame 16 slidable on pins 17 and moved into engagement with one flange of a pulley 3 by cams 8, 9 upon rotation of a knob 6. The roller 13 is rotated by means of a serrated cup-shaped member 11 actuated by a spring-loaded push-and-turn knob 14. The driven flange of the pulley 3 is of greater diameter than the other flange and the adjacent pulleys are prevented from moving by the pressure of the frame 16 against their flanges. This frictional driving gear may be replaced by toothed gearing, and the two operating knobs 6, 14 may be replaced by a single push-and-turn knob. The cords are divided into groups G-L and each is painted black over half its length, the other half of each cord being variously coloured. Corresponding cords in each group have the same colour. Each cord has a coaxial screen 33, Fig. 7, by which it may be concealed from view, the cord being normally seen through a longitudinal slot 34 on the screen. The screens are rotated through linkage by knobs A-F, the screens of corresponding cords in the various groups being connected to the same knob. The cords are protected by a glass front which may be engraved with horizontal lines. Removable strips 45, 46 are suitably graduated to form scales of time, distance &c. Flat bands may be used instead of cords, in which case a flat slotted screen may be used.

Title: Means for automatically correcting for gain variations of a measuring system
IPC: G01R17/02
Filed: 1975-05-21
Abstract: 1508193 Automatic gain correction RAILWEIGHT Inc (UK) Ltd 11 May 1976 [21 May 1975] 21703/75 Heading G1A [Also in Division H3]  Means for correcting for gain alteration in an electronic measuring system in which a train of pulses representing by its frequency the magnitude of the parameter measured is counted over a predetermined time interval, includes means for providing a reference count, means for generating the representative train of pulses, means for counting them, means for comparing this count with the reference count, to determine the error and means for automatically adjusting said time interval to correct for the effect of the error. Where the predetermined time interval is determined by a predetermined count of pulses from a clock followed by a divider, the adjustment may be by altering the clock pulse rate or the dividing factor or adding to or subtracting from the clock pulses. In the weighing device of Fig. 1 a weigh gate 6 is enabled for said time interval to supply counter and display 7. Gate 6 is opened and closed by flip-flop 21 at a time interval of say 0À28 derived from crystal oscillator 17 of 100 KHz. Thus when a predetermined count has been received by decoder 20, it turns flip-flop 21 back to close gate 6. To be able to alter the count interval over a range of say 100 pulses, a nominal correction pulse value of 50 is set in unit 10. When a correction cycle is required a command signal is received on line 26 and control circuit 9 causes an automatic zero control cycle, connects precision reference 4, simulating full load, to circuit 1, sets auto gain gate 8, resets divider 19 and decoder 20 to to zero and sets the nominal correction pulse value in circuit 10 in gain counter 11 and so into gain store 13. Due to clock pulses from oscillator 17 flip-flop 21 is set opening gates 8, 16 and 24. Twice the number of the nominal correction value i.e. 2 x 50 pulses are added via gate 8 to the clock pulses. When flip-flop 21 resets closing gate 8, gain counter 11 is left with a count, which, if it differs from the full scale count including the nominal correction value by more than  50 causes circuit 12 to provide a warning. The last two digits are transferred to store 13 as a correction value for subsequent weighings, in which delayed correction pulses are added to the clock pulses through OR gate 8 until comparator 14 senses equality of counts in counter 15 and store 13 and closes gate 24. In the weight system of Fig. 2 (not shown), a load cell bridge (101) is used and the reference is introduced by using precision resistors (105) and switches (106) across appropriate arms.

Title: Improvements in or relating to the formation of evaporated layers
Inventor: LUBSZYNSKI HANS GERHARD
IPC: C23C14/24
Filed: 1954-07-27
Abstract: 782,983. Coating by vapour deposition. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 25, 1955 [July 27, 1954], No. 21831/54. Class 82(2) [Also in Group XL(a)]  A layer of uniform thickness is formed on a surface by evaporating material to form the layer from a point source disposed at a distance from said surface and from a ring source disposed closer to said surface than the point source, the point source being on the axis of the ring source. As shown, an electron discharge device comprising an envelope 1 and glass window 2 is first provided with a transparent conducting layer 3, by spraying the window when hot with a stannous or stannic chloride solution, and then with a spongy layer 4 of the photoconductive antimony trisulphide by evaporation from (a) a point source 8 which may be a Ta boat containing the antimony trisulphide or a filament containing a bead of the material and (b) the ring source 7 formed by evaporating on to the surface of the ion trap mesh 5 a ring of antimony trisulphide. The deposition is performed in argon at a pressure of about 1 mm. Preferably the deposition from the point source is interrupted after half the quantity of antimony trisulphide therein has been deposited in order that the mesh 5 may be cleared by heating so as to sinter the deposit thereon but so as not to cause evaporation from the mesh or ring source. The remaining antimony trisulphide is then evaporated from the point source and finally the antimony trisulphide is evaporated from the ring source and mesh by e.g. eddy current heating the anode 6. During deposition from the point source, the window 2 may be maintained at a temperature of 50‹C. and during the evaporation from the ring source and mesh, the window may be kept cool by immersing it in iced water.

Filed: 1957-07-10
Abstract: 824,809. Change-speed control. FORD MOTOR CO. Ltd. July 10, 1957 [July 12, 1956], No. 21919/57. Class 80 (2). [Also in Group XXXV] A push-button selector, for mechanically operating the range selector valve of an automatic change-speed transmission on a vehicle, comprises slidably mounted keys 20, 22, 24, 26, 28 carrying push-buttons D, L, R, P and N/S respectively, and each having a pair of spaced selectively positioned abutments which, when the key is depressed, engage parallel bars 102, 104 of a common frame 92 to turn the frame about an intermediate axis 98 to a selected position corresponding to the particular key, frame movement being transmitted to the transmission range selector valve through a single Bowden cable 110. Depression of the Park button 132 and Reverse button R is positively prevented above 5-7 m.p.h. by an output driven governor energizing a solenoid 208 which pivots abutments 218, 220 into the path of the said keys. The depressed key is latched depressed by a detent bar 64 common to all keys and spring pressed to engage a shoulder 66 on the depressed key which it retains until depression of a further key causes a cam surface 67 on that key to pivot the detent bar 64 away from the shoulder 66 of the previously depressed key to permit movement of the frame 92 to initiate return movement of the previously depressed key, releasing it from an individual spring detent 86, whereupon a spring 58 completes return movement of the key. The usual transmission park-brake is actuated through a Bowden cable 142 by a full-width push button 132, which is connected to the park key 24 and overlaps the side of the casing to permit its being pulled up to release the brake by force if necessary. An additional button 34 is for releasing the usual emergency brake. Depression of the neutral-start button N/S beyond neutral position closes a switch 190 energizing the engine-start circuit, whilst depression of the Reverse button R closes a switch 184 lighting reverse lights on the vehicle. Light from a lamp 170 may be conducted by a plastic element 174 through an opening 177 in the front panel to light the brake release key 34, and a general front light may also be provided.

Title: Improvements in or relating to gearing for the transmission of power
IPC: F16H3/68
Filed: 1945-08-27
Abstract: 594,507. Variable - speed gearing. FARRELLY, M. M. Aug. 27, 1945, No. 21938. [Classes 80(i) and 80(ii)] Epicyclic worm gearing comprises one or more planetary worms 9 having a helical groove 19 engaged by a helical rib 15 inside an annular driving element 1, 5, and worm threads 18 engaged by a toothed wheel 7 attached to the driven member 12. The worms 9 are of barrel shape of the same curvature as that of the interior of the driving member and are supported tangentially on the periphery of a freely mounted disc 8. Friction between the helical rib 15 and the groove 19 is minimised by mounting long diamonds 20 in the surfaces of the helical teeth 18 so as to stand slightly proud of the surface. These diamonds have a smooth rounded front surface and a flat back to prevent them from rotating, and they are retained in position by plugs 21. Friction in the gearing is effective in producing a drive variable with the load. In a modification the toothed wheel 7 and the threads 18 of the worms 9 are omitted. In this case the worms 9 are carried on the driven member. A clutch may be incorporated to give a direct drive. Packing rings may be secured to the parts 1, 5 to prevent escape of lubricant from the interior of the annular element 1, 5.
