IPC: G06G7/70
Filed: 1971-04-19
Abstract: 1301976 Simulating time-dependent processes SINGER CO 19 April 1971 [27 March 1970] 23846/71 Heading G4G  Integrating apparatus for driving an indicating instrument 48 comprises an integrating circuit 34, 42, 44, 45 having a primary input representing rate of change of the indicated value, and two secondary inputs, respectively in the form of a steady voltage and an intermittent voltage of opposite polarity; to prevent cumulative errors in the circuit. As shown, the integrator forms part of a fuel-depletion simulator in which signals representing fuel flow from two tanks are fed over lines 12, 14 from an A/C flight simulator 10 through tank-selector switches 24, 26 to the input of integrating amplifier 34. An additional input of -15 V applied at terminal 40 is in the nature of an error signal which tends to drive the output of integrator 34 positive and is much greater than any error produced by imbalance of the integrator, or leakage of capacitors 42, 44 or diode 45. A second additional input of + 15 V from terminal 43 is applied to the integrator during one time increment out of eight at the rate of 1600 increments per second and balances the just additional input during such time increments. Thus, the integration rate of the first (steady) additional input is intermittently returned to zero. For seven increments out of eight the + 15 V input is returned to earth through FET 47 controlled by an amplifier 30. The inverting terminal of the amplifier is connected to a source 32 of + 15 V and the non- inverting terminal to an AND gate 28 having three pulsed inputs respectively of frequencies 400, 800 and 1600 cps. The + 15 V input is inverted by the amplifier whenever all three pulses are present at the AND gate input.

Abstract: 185,739. United Shoe Machinery Corporation, (Assignees of Perry, F. H.). Sept. 6, 1921, [Convention date]. Cutting.-Relates to machines of the type described in Specification 145,847 for trimming the heel end of a shoe sole to prepare it for attachment to a heel, and consists in means for adjusting the machine to trim seats for differing heels and means for gauging the heel to ascertain the requisite adjustment. As shown, the heel to be fitted is placed on a plate 60, Fig. 3, with its breast against an abutment 62. A handle 40 operating a slide 34 carrying rand crease engaging plates 30, all as described in the abovementioned Specification, is then moved until a gauge 64 carried by the slide 34 contacts with the heel. The shoe is then swung so that the margin of the heel end of the shoe is engaged by the plates 30, and the clutch is tripped so that the roller 74, Fig. 2, depresses the centre of the heel seat and the horizontally and vertically reciprocating knives trim off a U-shaped portion as described in the above-mentioned Specification. To prevent thin soles from buckling under the push of the horizontal knife, the plates 30 are serrated at 70, as are also the adjacent parts 72 of the shaft carrying the roller 74. The roller is also positively rotated by a pinion 76 smaller than itself so that the sole is wiped towards the horizontal knife as this advances. The vertical knife descends to assist in holding the work as the horizontal knife moves forward, the latter knife pauses while the vertical knife is raised out of the way. Then, after the horizontal knife has completed its cut and withdrawn, the vertical knife again descends to sever the U-shaped shaving-

Nov. 24, 1950 [Sept. 21, 1949], No. 24311/49. Class 39(ii) A portable battery lamp comprises a dished base 1, made of thin sheet metal such as anodized aluminium alloy, with a rigid, preferably diecast chassis 16 secured within it and extending around its interior to provide a reinforcing lip or edge to engage and locate a dished cover 2 hinged at the upper end of the base and provided with an opening within which a reflector 11 and bulb-holder 15 a r e maintained by a lens 9 and retaining-ring 10, a bridge 18 formed integrally with the chassis 16 and extending transversely between opposite sides thereof being apertured to receive the back of the reflector and inner end of the bulb-holder when the cover is closed. The cylindrical inner end of the reflector 6 is screw-threaded as far as an internal flange 12 against which a holding-disc 13 for a pre-focussed lamp bulb 14 is held by a threaded insulating- sleeve 15. When the cover 2 is closed the central contact of the bulb is engaged by a contact strip 27 which is mounted on the upper limb of an inverted L-shaped element 20 which is integral with the bridge portion 18 of the chassis 16, the contact 27 being insulated from the element 20 and conected to a contact member 28 in engagement with the top terminal 29 of the battery. A switching-contact 24 at the upper end of a further contact strip 21 completes the lamp circuit when pressed against the reflector 6 by the depression of a plunger 30 mounted on the upper end of the base 1, the lower end of the strip 21 being normally in abutment with a battery contact 22. The vertical limb of the element 20 is secured to the base 1 by rivets 20a, and thus maintains the chassis in position; in addition, it serves also to maintain the contact strio 21 in position beneath it with interposed insulating strips 25, 26 A clip to hold a spare bulb may be mounted on the bridge portion 18 of the chassis. A bowed metal strip 37 at the lower end of the base serves to press the battery contact 29 upwardly against the adjacent fixed contact 28, and a sliding-catch 33 operated by a push-button 34 is movable relative to the base 1 to retain the cover 2 in the closed position. A wire carrying-loop 39 pivotally mounted on the rear of the casing may be narrowed to the form of a keyhole-slot at its upper end for attachment to a button on a garment. Alternatively a resilient metal tongue that can be hooked upon a belt is provided.

W. ; Port Jefferson, Long Island, New York, U.S.A.) Aug. 23, 1934, No. 24349. Convention date, Aug. 23, 1933. [Classes 39 (i) and 40 (v)] A thermionic amplifier giving substantially equal amplification over a very wide band of frequencies employs discharge tubes having a magnetic field parallel with the cathode, the output electrode of one stage being directly connected to the input of the stage succeeding. Fig. 2 shows a direct coupled cascade amplifier in which the input is applied between anode and cathode of the valve V 1, the grid electrode 13 of which is connected to the anode of the succeeding stage V2. The construction of these valves is shown in Fig. 1 ; the grid 13 is constructed with widely spaced radial vanes and is close to the anode 12. Equal positive potentials are applied to both grid and plate and the axial magnetic field of the winding 14 is adjusted to such strength that electrons reach the grid only, no current being set up. from the anode. Variations in anode potential due to signal from 5 thus vary grid current through the resistance R2 ; the anode potential of V2 is thereby varied causing further grid current fluctuations in R3 and so on. Fig. 3 shows an amplifier arrangement, employing direct coupled split anode magnetrons. Variations in potential of input electrode 15 cause changes of current from the output electrode 16 thus varying the potential of the following input electrode through the resistance Z1. A push-pull arrangement of magnetrons is shown in Fig. 4, the couplings between input and output being neutralized by condensers NC. Inductances CL in series with the coupling resistances correct the response at higher frequencies.
