Title: Improvements in and relating to Level Indicating Instruments.
IPC: G01C9/06
Filed: 1918-01-14
Abstract: 130,076. British Thomson - Houston Co., and Young, A. P. Jan. 14, 1918. Clinometers.-Apparatus for indicating, without errors due to centrifugal force or temperature, the degree of inclination of aircraft or other vessels comprises a magnet fixed to, and partaking of the movements of, the vessel, and a conducting-disk mounted so as to rotate freely and in such relation to the magnet that it will follow the movement thereof after a definite interval of time, the deflexion of the vessel being obtained by integrating the difference between the relative angular velocity of the two members throughout the movement. In the apparatus shown, a permanent magnet 2 is fixed relatively to the aeroplane or vessel, and a balanced disk 1 of a conductor, such as copper or aluminium, is mounted between the poles so as to be free to rotate substantially without friction, so that when the vessel tilts, the disk 1 will, after a time interval, follow the movement of the magnet. A light commutator 3 is mounted on the axis of the disk 1, and brushes 4 bearing on the commutator are carried by the magnet or some fixed part of the casing of the apparatus. Two fine-wire resistances 5, Fig. 2, are carried by the 'disk or within a flat casing 6 on the disk spindle, and tappings are taken from these resistances to segments of the commutator in such a manner that the resistance included in the circuit when the commutator rotates relatively to the brushes is inversely proportional to the angular displacement, which is in this case proportional to the relative angular velocitv. An electric circuit is completed from a dry cell or the like 13 when the brush moves off a dead-segment of the commutator. The indicating-device comprises a flat armature 7 enclosed in a thin aluminium cylinder rotating between the poles of permanent magnets 8. This armature is included in the circuit through brushes 9 and a commutator 10 when the brushes 4 are on any of the live-segments of the commutator 4, and takes up a position according to the tilt of the vessel, a graduated dial on the armature being read through an aperture 11 of the casing. Mechanical means may be employed for integrating the relative angular velocity of the conducting-disk and fixed magnet 2. Push-button switches within reach of the pilot may be provided to enable the armature 7 to be zeroized.

Title: Improvements in or relating to radio and other high frequency transmitters
IPC: H03B5/34
Filed: 1931-01-09
Abstract: 366,248. Valve generating and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand,' London.-(Assignees of Hansell, C. W. ; Port Jefferson, Long Island, New York, U.S.A.) Jan. 9, 1931, No. 841. Convention date, Jan. 31, 1930. [Class 40 (v).] A radio transmitter suitable for use on aircraft comprises a tetrode valve oscillator with a feed-back circuit (including frequencydetermining means such as a piezo crystal) connected between the anode and one grid, and with the microphone connected between the other grid and the cathode. Signal voltages from the microphone 54 are applied directly to the inner grid 55 of the oscillating valve 40. The tuned plate circuit 41, 42<1> has a midpoint connection to the dynamotor HT supply 43, and the opposite end of the coil 41 is connected to two crystals 49, 50 either of which may be connected to the outer grid 48 by the switch arm 53. Positive voltage is applied to the grid 48 through a resistance 46 and choke coil 47. The oscillator thus funetions at either of two frequencies, one for calling and the other for signalling, according to the position of a two-way switch 91 which connects the battery 54<1> into circuit with the selected portion of the relay coil 92 operating the arm 53. The control circuit of the relay 92 includes a switch 90 which is preferably arranged as a send-receive switch mounted on the microphone casing when the apparatus is installed on an aeroplane. The switch 56 supplying the filament and the dynamotor is kept closed during sending or receiving. The aerial circuit 80 is coupled to the tuned circuit 41, 42<1> and includes a thermo-couple 82 connected to a meter AM for reading the aerial current. Grid bias is afforded to the inner grid 55 by means of a resistance 44 traversed by the plate current. Byepass condensers are provided at 70 .. 73. The Specification as open to inspection under Sect. 91 (3) (a) includes the circuit shown in Fig. 1 (Cancelled), in which a screen-grid oscillating valve 1 has a tuned plate circuit 5 connected to the inner grid 13 by a condenser 14 and to the dynamotor HT supply 6. The grid circuit comprises a choke coil 9 and grid leak 11 shunted by a condenser 10. Signal voltages from the microphone 15 are amplified by the valve 19, the plate circuit of which includes a resistance 24. Voltages across the resistance 24 are applied through a resistance 22 to the screen-grid 21 of the valve 1. Oscillations generated in the circuit 4, 5 and transferred to the aerial 8 are thus modulated by the signal. The dynamotor is supplied from a D.C. source 25 through a switch 26 and fuse 30, a branch circuit serving to heat the filaments of the valves 1, 19. The grids of these valves are biased by resistances 12, 16. This subjectmatter does not appear in the Specification as accepted.

Abstract: 449,885. Alternating-current motors. BRITISH SANGAMO CO., Ltd., and BUTHERUS, F. R., Cambridge Arterial Road, Enfield, Middlesex. Jan. 10, 1935, No. 885. [Class 35] [See also Group XXXVII] A synchronous motor has an element to render it self-starting and the rotating field is rendered effective or ineffective by an operation which, if repeated after synchronism has been attained is unable to affect the synchronous running of the motor. In the form shown, the stator plate (i has two sets of teeth for cooperation with a permanent magnet rotor 10 and', in addition, polepieces 5 which, with polepieces on members 3, 4, co-operate with an induction rotor 9. The members 3, 4 are separated by a shading coil 8, the circuit of which is opened when it is desired that the motor shall not be self-starting. The shading effect may, alternatively, be annulled by angularly moving magnetic members to bridge the polepieces on members 3, 4. The members 3, 4 are separated by a shading coil 8, the circuit of which is opened when it is desired that the motor shall not be self-starting. The shading coil, in another modification, comprises a slotted disc, the slot of which may be bridged by a peg. The shading coil circuit may be closed by switch contacts 15, 22 when the rod 13 is at the bottom of the slot in the plate 17. If the switch 'is to be maintained closed the rod 13 is raised to the position shown so that the pressure of spring 19 on collar 18 on the rod is ineffective. Specification 384,880 is referred to.

Title: Photodetecting device
Inventor: KIGUCHI MASAO
IPC: G01V8/12
Filed: 1988-01-04
Abstract: PURPOSE:To eliminate the need to adjust the sensitivity of a sensor for each product with a variable resistor and to cope with a shift in the mechanical fitting position of the sensor by controlling the quantity of light of a light emission part so that a photodetection part operates in an unsaturated area. CONSTITUTION:A reference voltage Vref1 for detecting whether or not a voltage exceeds a collector saturation voltage Vce(sat) is set as the threshold voltage of a comparator 8 in addition to normal Vref2, and they are switched by a CPU 13. A LED current is set to If1 and the threshold voltage is set to the Vref1. Then when the output voltage Eout of a phototransistor (Tr) 1b is smaller than the voltage Vref1, the Tr 1b is not saturated, so the LED current is set to If1 and information on that is stored in a nonvolatile RAM 14. When voltage Eout>=Vref1, on the other hand, the LED current is switched to If2 and information on that is stored in the RAM 14. Then when the system is powered on, the values of the RAM 14 are outputted to an output port 11 and the CPU 13 operates the photosensor 1 while grasping variation of the element.

Title: Decreasing haze in transparent coated article
Inventor: JIYOOJI EE NIYUUMAN
IPC: C03C17/34
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To decrease haze of the surface of an article by constituting the article of a coating film wherein the level of the surface haze of the second surface of the coating film is lower than the level of the surface haze of the main surface of a substrate, and an article with the min. surface haze is provided. SOLUTION: An article 62 contains a piece of glass 64 with e.g. a pyrolytically decomposably applied tin oxide film layer 68. A surface haze decreasing film 60 is applied on the boundary surface 40 of the layer 68 and this film 60 has an enough thickness for smoothing the rough surface of the boundary surface 40 or the surface of the layer 68. In addition, the pref. thickness for making the roughness disappear depends on a selected material as a haze decreasing film 60 and the method for accumulating it. e.g. if the haze decreasing film 60 follows the rough surface, namely, the pattern of the rough surface of the layer 68, the lowest haze is realized.  In addition, the optimum decrease in haze can be realized when refractive index of the haze decreasing film 60 is equal to the refractive index of the layer 68 on the boundary surface 40 and when a smooth surface to the incident medium exists on the boundary surface 40.

Title: Receiver, reception method and terminal equipment for radio system
Inventor: NARUSE TETSUYA
IPC: H04B1/7115
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To make a search time fast, to surely set an optimum path to a finger and to set a threshold, corresponding to the number of times of addition at a searching time in a receiver of a RAKE method. SOLUTION: In the case of obtaining a correlation value with a received code, while shifting a phase of a PN code for each prescribed tip, the correlation value is obtained by accumulating inverse spread outputs. In this case, a threshold generating circuit 61 generates a threshold, corresponding to the number of times of cumulative addition of the inverse spread outputs. That is, the threshold is increased corresponding to the increase of the number of times of cumulative addition. Or the number of times of cumulative addition is normalized and the result is compared with the threshold. When the number of times of cumulative addition does not reach a prescribed threshold level, as the correlation is weak, the phase is immediately shifted to the next.

Filed: 1988-01-06
Abstract: PURPOSE:To realize the re-search of a target even in case the target is lost by estimating a meeting point between its own plane and a target plane for decision of the course of its own plane. CONSTITUTION:A calculation circuit 6 calculates the present position coordinates at a prescribed interval based on the distance from a target plane and the direction of said plane obtained by a calculation circuit and the present position of its own plane obtained by an estimating circuit 5. The flight path of the target plane is approximated by an N-degree curve (N: an integer of >=2) of a time function. Then each coefficient of an evaluation function is obtained so that the evaluation function obtained the position coordinates of the target plane of the past M times is minimized. Then an optimum approximation formula closest to the flight path of the target plane is calculated out of the N-degree curves. The distance between its own plane and the target plane is estimated from the positions of both planes set after (t) seconds and obtained from said optimum approximation formula. Then the time (t) is obtained from said estimated distance and the course of its own plane is estimated with the time (t) minimized. Thus the flight of its own plane is controlled along the estimated course. In such a way, a target can be searched again with great possibility even though the target is lost.
