Title: Receiver with interference wave prevention
Inventor: ATOBE MASAAKI
IPC: H04B1/16
Filed: 1992-01-06
Abstract: PURPOSE:To allow the receiver to be immune to the effect of an interference wave even when the wave is incoming or produced in the vicinity of the receiver by providing an interference wave protection AGC and an AFC control circuit to a digital communication receiver. CONSTITUTION:An AGC or AFC control value inputted from a terminal 103 or 104 is given to a control value abnormality detection circuit 14, and when the circuit 14 detects a rapid change of a prescribed value or over, a changeover device 15 is thrown to the position A and a prescribed control value in the normal state generated by a control value generating circuit 13 is outputted to a terminal 105 or 106. Thus, a control signal causing a rapid change is not outputted to the terminals 105, 106.

Abstract: 1,025,380. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 4, 1965 [Feb. 19, 1964], No. 266/65. Heading B6F. An escapement mechanism comprises a rack 1 urged in a direction F 1 , a single pawl 3, and a holding control element 7 which, to effect release of the rack 1, is moved first to relax the force which holds the rack and then to move the pawl 3 clear of one tooth of the rack and into the next. In the rest position shown, rack 1 engages the nose of pawl 3 and pawl 3 is held against movement by an outwardly extending brace 15. A stud 11 on the pawl 3 is free from engagement with either end of a slot 9 in the control element 7, and slot 21 in the pawl 3 is free from a main frame pivot 5 which holds the rack via its engagement by the right-hand end of an irregular opening in the control element 7 When an escapement action is required a force E is applied to the left end of the control element 7 and a pivot point about the stud 11 and the slot 9 is found. This displaces the brace 15 from behind the pawl 3 without any friction, and the force between the pawl 3 and the rack 1 is relaxed. With the strain relieved the pawl 3 is pivoted out of engagement with the rack about stud 5.

Title: Process and apparatus for the synchronising of moving parts, particularly suitable for the transmission of pictures to a distance
IPC: H04N5/04
Filed: 1927-01-07
Abstract: 264,481. Karolus, A. Jan. 18, 1926, [Convention date]. Synchronous movements for copying-telegraph, television, and other telegraph systems. The speeds of the driving motors at the transmitting and receiving stations are each controlled by a local thermionic oscillation generator, and synchronism is obtained by local adjustment of the frequencies of these generators without any transmission of a synchronizing action between the stations. As applied to a copying- telegraph system employing transmitting and receiving drums 1 each driven by a motor 2, the motor shaft carries the rotor 4 of a phonic wheel or other synchronous motor with a driving magnet supplied from a thermionic generator 6 through amplifiers 7, 8. The picture currents amplified at 14 are supplied to the wireless transmitter 15, and at the receiving station are amplified at 19 and pass through the switch 24 in the position shown to the usual Kerr cell or like lightccntrolling device 20 associated with the receiving drum. When no picture is being transmitted the switch 24 may be moved from contacts 25 to contacts 26, whereupon, on closing a switch 22 at the transmitting station, the input circuit of the amplifier 8 is connected through a modulator 23 to the transmitter 15 to supply the frequency of the transmitting station generator 6 to leads 27 at the receiving station for comparison with the local generator frequency. For such comparison the leads 27 may be connected through a switch 28 to a lamp 11 co-operating stroboscopically with the teeth of the local phonic wheel rotor 4. Other known methods of comparison, optical, electrical, or acoustic may be used. Alternatively the two thermionic generators 6 mav be tuned to a constant difference of frequency, the numbers of poles in the rotors 4 or the gear ratios being such as to result in equal speeds of the drums 1.

IPC: E05B17/14
Filed: 1917-01-11
Abstract: 103,307. Bulgaris, C. de. Jan. 10, 1916, [Convention date]. Keyholes, obstructing; locks, permutation.-The keyhole of a door or other lock is obstructed by an oscillating plate, the position of which is controlled by permutation mechanism. The obstructing- plate 5, Figs. 2 and 3, is integral with a sleeve 8, which turns on the barrel 6 fixed to the plate 3 of a casing mounted in the door. When turned down, as shown in dotted lines in Fig. 2, the plate 5 closes the keyhole x of the main lock 1. In this position, the plate 5 is secured by the bell-crank lever 9, 10, the end 12 of which engages the spring 13 on the back of the plate. When the combination is set so that notches 22 on the disks 19 are in line with the stud 18, the spring 17 presses the arm 9 of the bell-crank lever forward, and its end 12 is lowered out of engagement with the plate 5. The plate can there be turned by the button 7, which engages the tube 8, to a position in which the keyhole x is uncovered, the projection 27 ultimately pressing back the arm 9 of the bell-crank lever, withdrawing the stud 18 from the notches 22, and raising the end 12 of the lever to the position shown in Fig. 2. On turning down the plate 5 to close the keyhole x, the spring 13 yields and passes the end 12 of the lever. The permutation disks 19 are integral with concentric tubes 21 and are set by fingers 23 in front of an indicator plate 25. The position of the fingers 23 with regard to the tubes 21 can be altered to change the combination bv pulling forward the button 7 which allows the studs 29. Fig. 7, on the fingers to be disengaged from notches 28, Fig. 6, in the ends of the tubes. The button 7 is mounted on a stem 30 which passes down the barrel 6, and the groove 31 in its end is engaged by a catch which passes through a slot 32 in the barrel. The catch is only released when the stud 18 on the lever 9 is within the notches 22 of the permutation disks 19, so that the button can only be pulled forward when the combination has been set.

Title: Improvements in and relating to earth leakage protective systems
IPC: H02H3/16
Filed: 1940-01-15
Abstract: 535,446. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., TURNER, H. C., and EDSALL, E. A. M. Jan. 15, 1940, No. 857. [Class 38 (v)] Electrical apparatus 1, such as a cooker with its element 2 fed. through circuit-breaker 5 from a supply having its neutral 4 earthed only at the feeding-point 11, is connected over normallyclosed test key contact to the junction point of oppositely-wound trip coils 6, 7 for the breaker 5, the other ends of the trip coils being connected to the neutral 4 and an earth connection 10, respectively. When the line, which is assumed to be long, carries a heavy load, the alternating potential-to-earth of the neutral 4 at the apparatus 1 sends a current through the coils 6, 7 but without effect; by suitably proportioning the turns, however, tripping may be produced when, due to a break in the neutral between the breaker 5 and the supply, a high neutral potential is set up. Tripping is produced when currents flow in opposite directions through the trip coils due to a leak between the element 2 and apparatus-frame. If the frame 1 is independently earthed at a distance from electrode 10 so as to shunt some of the current from coil 6 away from the coil 7, the latter must have more turns. A high frame-potential can be simulated for tripping the breaker by depressing test key 9 and connecting the phase-wire 3 to the coils over contact 12 and resistance 13. The windings may be shunted by radio-interference suppressing condensers (not shown) and may comprise two separate coils or a doublewound coil. In order normally to restrict the frame-potential relative to that of the neutral, the resistance of the frame-to-electrode 10 circuit is equal to, or less than, the frame-toneutral circuit, and the winding in the latter may have an impedance in series with it.
