Title: Circuit arrangement for detecting the signal of the greatest value from a set of signals
IPC: G06V30/194
Filed: 1962-01-19
Abstract: 956, 896. Detection of signals of maximum amplitude or duration. STANDARD TELEPHONE & CABLES Ltd. Jan. 19, 1962 [Jan. 20, 1961],No. 2033/62. Heading G1U. [Also in Division G4] A circuit for detecting a signal of maximum value in a plurality of sequential signals comprising a signal receiver arranged to store the first signal of a sequence, and of the subsequent signals only a signal of greater value to replace a previously stored signal, a sensing circuit activated each time a signal is stored in the signal receiver, and a storage means controlled by the sensing circuit to record information identifying the position in the sequence of a signal of maximum value. In Fig. 1, plural signals are applied over channels 1 to n to normally open gates 11 which are closed in succession by counter 12 whereby the signals are connected in succession to signal receiver 13 which stores the first signal and releases the evaluating circuit 14, which operates storage device 15 to record the number of the channel. On arrival of a signal exceeding in magnitude the previously stored signal the latter is cancelled and replaced by the greater signal, and the number of the relevant channel is again recorded in device 15, so that after connection of all input channels to the signal receiver, the number of the channel in which the largest signal is received is recorded in device 15. When the signals arrive successively over a single line, gates 11 are omitted and counter 12 is operated from the signal input or a train of clock pulses (Fig. 2 not shown). The signal receiver 13, responsive to undirectional signals, comprises (Fig. 3) a storage capacitor C fed through diode D and the primary of transformer ³, which on charging in response to the first signal develops a secondary pulse triggering the evaluating circuit 14, comprising amplifier, threshold device, and monostable trigger circuit, into its unstable position, which impulses the counter to recored the channel number in storage device 15. Application of signals of lesser amplitude through successive gates leaves diode D, blocked but a greater signal again charges capacitor C over the diode and transformer U and again pulses the evaluating circuit to record the new channel and erase the former one, so that on completion of a cycle the store 15 indicates the channel having the greatest input signal. Prior to commencement of a new cycle, the capacitor is discharged by closure of switch S. Alternating input signals may be rectified prior to gating or storage. A resistance capicitance integrator may precede the circuit of Fig. 3 (Fig. 4 not shown) and the apparatus then responds to indicate the signal having greatest pulse duration.

Abstract: 122,710. Bolotoff, S. V. de. Feb. 5, 1918. Addition to 113,467. Framework.-In a device for receiving strut-ends in aircraft and other structures comprising two spaced angle-plates as described in Specification 113,467, the angle-plates are arranged so that their sides or edges are not parallel in order to accommodate tapered struts and longerons, and single securing pins passing through each strutend may be used. Figs. 1 and 2 show two plates A, B arranged for assembling a tapering strut D and a strut E at an obtuse angle upon a tapered longeron C. The plates are secured together by four bolts F with spacing-pieces G arranged to prevent lateral movement of the struts. Fig. 5 shows a modification in which the plates are secured together by two set screws H, passed one through each strut and into a block J having a wiring-eye K. A modification is described in which the angle edge is bent to take a double. tapered longeron. Lugs may be provided on the angle-plates to engage the sides of the struts.

Abstract: 291,776. Ingersoll-Rand Co., (Assignees of Hansen, C. C.). June 9, 1927, [Convention date]. Lubricant conveyed by fluid.-In a lubricating device comprising a casing A forming an oil reservoir D and having threaded apertures G in its ends for connection with the air line H of a pneumatic machine, a tubular member L journaled in the ends of the casing coaxially with the apertures to and forming a pressure-fluid passageway 0 carries weights P extending close to the ends of the casing and having passages S leading from the reservoir into axial passages R in bridges Q extending transversely across the passageway 0, the outlets of the passages S being controlled by needle valves U threaded into the bridges. A pipe Y carried by the tube L conveys pressure fluid from the passageway 0 into the reservoir D, the arrangement being such that, due to the fluctuations of pressure in the line consequent on the operation of the machine, oil is forced from the reservoir into the passageway 0 through the passages S. The weights P ensure that the tube L takes up a position such that at least one of the passages S, the inlets T of which are. near the ends of the casing, is in communication with the oil in the reservoir, and that the pipe Y projects about the surface of oil, irrespective of the position of the casing. Access to the valve U is obtained through openings E, W normally closed by screwed. plugs.

Filed: 1923-01-24
Abstract: 194,267. Huguenin, A., and Gagg, A. Feb. 28, 1922, [Convention date]. Rotary spherical valves.-The closure facing of a rotary spherical valve is formed separately from the valve member, and is pressed against its seating by fluid pressure, which may be released when the valve is opened. The valve 4 is mounted on pivots 2, 3 and is provided with a facing-member 8 sliding in a short cylinder 7. Fluid pressure is admitted to the space 9 through an opening 10, and the pressure may be relieved when it is required to open the valve by opening a valve 13 which communicates with the outlet side of the main valve. In a modification shown in Fig. 4, the member 8 may be forced away from its seating when required by admitting fluid pressure behind it through the by-pass conduit 16 and valve 17. In another modification, Fig. 5, the member 8 is retracted by means of a resilient disc 18, when the pressure in the space 9 is relieved.

Filed: 1916-02-19
Abstract: 100,091. B³chi, E. F. Feb. 19, 1915, [Convention date]. Sights and methods of sighting. -Consists in a combined observing and calculating instrument for use in artillery work or for surveying purposes, comprising a prismatic compass arranged in conjunction with a goniometer scale whereby the hearing of an object can be determined with correction for magnetic declination, and also with a pair of circular scales to facilitate the calculation of battery angles. The device may be turned into a vertical position for clinometrical measurements and is provided with a spirit level. The apparatus is arranged in a casing comprising upper and lower compartments 1, 2 and a cover 3. In the lower compartment 1, a compass card 5 is mounted on a pin 4 and may be put out of action by the usual spring and a lever 7. In the upper part 2 of the casing, the goniometer scale 13 is fitted in an opening in one wall and an eyepiece lens 14 in the opposite wall. In front of the goniometer scale, a prism 10 reflects compass readings from the card 5 to the lens 14, an opening 9 in the floor being provided for this purpose. By this means the bearing of a distant object such as a tree, Fig. 2, may be readily determined, the centre mark of the goniometer scale, corrected for magnetic declination, being directed on the object, and the compass reading which gives the hearing being simultaneously visible in the field of the eyepiece. To enable the device to be used as a clinometer, it is turned into an upright position, a mirror 18 to reflect the spirit level 16 into the eyepiece, being turned into the position shown in dotted lines in Fig. 3, by the same lever 20<1> which puts the compass out of action through the medium of the lever 7 and spring. A pair of circular scales 21, 22, the inner one fixed to the bottom of the casing and the outer one rotatable, is provided to facilitate the calculation of the battery angle c, Fig. 4, after the angle b between the sighting-point S and an aiming-point zp has been observed, and the bearing angle a of the target (unseen) to the meridian has been determined from the map.
