Patent ES-340855-A1 (ES)
Title: Nonreactive antisidetone network for a telephone set
IPC: H04M1/58
Filed: 1967-05-03
Abstract: A telephone subset contains an anti-sidetone resistive hybrid bridge and a receiver which is arranged to be connected directly to telephone line and to receive via transistor amplifier the out-of-balance currents produced in the hybrid bridge by speech-signals arriving on the line the bridge -remaining balanced and the receiver unaffected upon transmission from the subset. In Fig. 4, the line impedance Z L , the resistors R1 and R2 and non-inductive impedance Z N form a balanced bridge with the transmitter T effectively connected across one of the resistance arms. Upon transmission from the subset a current is is generated in arm R s and balanced by a current i N produced in X N by the transmitted signals. No current therefore flows through transistor amplifier Q 4 , Q 2 to the receiver R. Upon receiving speech signals over the line no current flows in R s to balance the current i N through Z N which is amplified and applied to the receiver R. By making the amplification of Q 4 and Q 2 large there is little loss of speech signal strength in the bridge and with Z N and R s large as well there is little loss in the transmitted signal strength. The input impedance of the speech circuit depends upon Z N and the amplification of Q 4 and Q 2 .

Title: Lead frame assembly for semiconductor devices
IPC: H01R12/55
Filed: 1968-12-16
Abstract: A method of making a multiplicity of lead frames for semi-conductor devices comprises providing a flexible strip of metal, vapour depositing a narrower strip of conductive material along one surface thereof, and removing portions of the flexible strip at intervals to produce a repetitious lead frame pattern having integral frame sections with spaced apart lead portions extending within each frame section. Ferrous strip for the frames is checked for correct dimensions and physical properties, degreased and coiled on a steel core, on which the coil sides are straightened. The strip is electron beam heated to facilitate the vapour deposition of a layer of aluminium (38), Fig. 6 (not shown), which has a thickness of 100-300 micro inches. The clad strip 40 is passed through a stamping die, where it is perforated to the frame pattern. The strip of lead frames is checked with an optical comparator, any faulty frames are cut out and the cut ends of the strip spot welded together. The strip is again degreased, liquid vinyl masking 42 is sprayed on and cured in an infra red oven. It is then etched in a sodium hydroxide solution at 160-180 F while preferably subjected to ultrasonic vibrations to remove the unmasked aluminium. The etched strip is rinsed in tap water followed by deionized water and then passed through baths of diluted sulphuric acid, tap water, de-ionized water, alcohol and a drying oven before it is recoiled. The frame is next gold plated, preferably after the application of a layer of nickel plating. The vinyl masking is removed in an acetone tank and samples may be taken as it emerges therefrom for quality control purposes. Any remaining traces of vinyl are removed in a solution of five parts of water to one of sulphuric acid. Substrate units may be secured to the frames while they are still in strip form. The units are of ceramic, e.g. aluminium oxide, and are provided with a thin layer 34 of glass frit, which is heated until it becomes viscous and the leads 26 are pressed into it and become bonded thereto.

Title: Pushbutton depressible to actuated position against the force of one biasing means, and depressible to latched position against the force of two biasing means
IPC: G11B15/10
Filed: 1969-02-06
Abstract: A push-button unit for tape recording and/or playback apparatus comprises a push-button movable to perform a control function, after that as the push-button is moved means produce a perceptible resistance to the movement, and after that the push-button is latched into the operative position. As shown, Fig. 1, when push rod 3 is pushed to the left slider 7 is moved to the left by spring 9 connecting push rod 3 and slider 7. Slider 7 grips switch operating members 6 by means of projections 8 and when slider 7 is moved to the left switch operating members 6 are moved operating contacts 5 in switch units 4. When projections 8 encounter the ends of slots 14 in frame 1 slider 7 cannot move any further to the left and if push rod 3 is released it moves back to the right under the action of spring 2. If push rod 3 is not relaesed but is moved further to the left spring 9 is tensioned thereby offering a perceptible resistance to movement. At the completion of the stroke extension 18 on push rod 3 snaps behind spring loaded catch 17 to hold it in position. If catch 17 is released manually, push rod 3 moves back to the right under the action of spring 2 carrying slider 7 with it. In use the push-button is intended to rewind a tape, for example, the push-rod being depressed until the perceptible resistance is reached and then released when the appropriate spot on the tape is reached, the push rod being latched in for long rewinds. In a second embodiment, Fig. 4, push rod 3 is pivoted and when the push-button is depressed actuates switch unit 4, the push rod then coming up against a brace 21 and spring 20 which provides a perceptible resistance to movement of the push rod, which eventually latches behind catch 17.

Filed: 1972-08-03
Abstract: A toy successive missile launcher having a launching device and a transmission device. The launching device has a hollow complex cylindrical body having plural launching tubes, a circular disk, and supports for a plurality of launching levers and a rotatable shaft. The transmission device has a frame provided with a member, a reduction gearing, a changing lever and a motor. The launching device is connected with the transmission device by the rotatable shaft which is mounted on said frame. The cylindrical body is attached to the circumference of said disk and contains said lever support and said launching levers inside it. The transmission device is caused to operate by a motor. The transmission device causes the launching device, with the in place missiles, to rotate. As the launching levers rotate they engage the fixed cam on the frame and are caused to pivot out of engagement with the in place missiles. A compressed spring in each launching tube will project a missile once the launching lever has been pivoted from engagement with the missile. A new missile may be positioned for firing by placing it in the launching tube while compressing the compression spring. An elastic band is used to bias each launching lever so that once the missile is in place in the launching tube the forward end of the launching lever will engage a ring on the missile and hold the missile until the launching lever is pivoted out of engagement with the missile.
