Title: Improvements in or relating to circuits for providing a substantially noiseless output signal from a noisy input signal
IPC: H03K3/013
Filed: 1965-04-30
Abstract: 1,032,389. Pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 30, 1965 [May 1, 1964], No. 18242/65. Heading H3P. In a circuit for producing a noiseless output signal from a noisy binary input signal, the noisy signals are fed via an AND gate (2 or 9) to a pair of bi-stable circuits 3, 8 in cascade, the gate (2 or 9) being arranged to inhibit passage of noisy signals for a predetermined time after the bi-stable circuits 3, 8 have been set to a predetermined state. The circuit is preferably employed to eliminate the effects of contact bounce in changeover contacts 28, 44 controlled by a cam 30. When the cam 30 begins to close the normally open contact 28, the AND gate 2 responds to the first coincidence between potential on contact 28 and clock pulse from 18 so as to set bi-stable circuit 3 and enable the next clock pulse on line 33 to pass an AND gate 4 and trigger a monostable multivibrator 6. The output from 6 enables the next clock pulse on line 32 to pass an AND gate 7 and set a bi-stable circuit 8, initiating a noiseless binary output at 40. The output from 40 also disables the AND gate 4 whilst the output from 6, after inversion at 1, disables the AND gates 2, 9 until the end of the pulse from the monostable multivibrator 6 when the AND gate 9 will be responsive to the first coincidence between reclosure of contact 44 and clock pulse from 18. Bistable circuit 3 will then be reset, so that AND gate 10 will respond to the next clock pulse on line 33, retriggering the monostable multivibrator 6 so that bistable circuit 8 will then be reset by the next clock pulse on line 32 (fed to AND gate 11) hence - the output at 40 will exhibit a noiseless change to its original binary value. The duration of each pulse from the circuit 6 must be greater than the duration of contact bounce of contacts 28, 44.

The segments have interengaging teeth e, and have external ribs in the form of screw threads f, longitudinal ribs or circumferential ribs. When only two segments are used, lugs extending from the longitudinal edges of one may clip on to the edges of the other. The expansion member g is formed on the end of the bolt h ; alternatively, the expansion member may be in the form of a nut mounted on the bolt, the latter being prevented from moving axially by a rib received in a circumferential groove in the segmental parts. The expanding member may have axially extending wedge projections which enter between diverging parts of the segments. The segments may have claws engaging the end of the expansion member to prevent its dropping out when the bolt is removed. The cap b extends beyond the parts a and may have a circumferential groove u, Fig. 1 ; on tightening up the bolt the cap is deformed as shown in Fig. 5. Alternatively the cap may have radial grooves in its outer end face ; tongues may be bent down to engage the ends of the segments, or the end of the cap may be of reduced diameter for this purpose ; the cap may enclose a deformable washer.

Title: Process for the manufacture of sheets of thermoplastics filled with glass beads
IPC: B29C48/395
Filed: 1978-05-10
Abstract: The thermoplastic is mixed with the glass beads in a single-screw or multi-screw extruder, and the mixture is extruded directly to form a film. Compared with processes in which films are extruded from prefabricated glass-bead-filled thermoplastics, the process provides the advantage that the thermoplastic is subject to thermal loading only once and is thereby damaged less. In the films produced by the single-stage process, the glass beads are surprisingly distributed so uniformly that these films can be used for optical purposes.

Title: Improvements relating to television receiving apparatus
IPC: H04N5/08
Filed: 1955-06-28
Abstract: 799,786. Television. GENERAL ELECTRIC CO. June 28, 1955 [June 28, 1954], No. 18704/55. Class 40 (3). Synchronizing pulses are separated from the video signal by means of a double triode 70 to the first grid 73 of which the signal, Fig. 2, is coupled directly from the output of video amplifier 19 and to the first cathode 72 of which is applied a bias varying in accordance with the D.C. level of the signal so that the cut-off level is held at a level a, Fig. 2, just positive of the blanking pedestal and the triode conducts to pass only the synchronizing pulses. The separated pulses are then applied to the second grid 78 and are effective to cut off the second triode at a level b whereby substantially square pulses free from noise and interference appear across anode load 81 for application to the sweep circuits. In a second embodiment, Fig. 3 (not shown), the double triode is replaced by a hexode, the synchronizing pulses being separated as shown in Fig. 1 by holding the cut-off level just positive of the blanking pedestal, but the tops of the synchronizing pulses being removed by arranging the valve to run into anodecurrent saturation. The cathode bias for the separator is derived by means of an integrator circuit 41, 42, which receives the video signal from amplifier 19 and applies a potential via a first cathode-follower 43 to a further integrator circuit in the form of a low-pass filter 48, 49, 51, 52. The resulting potential, which corresponds closely to the black level of the signal and varies in accordance with it, is then applied via a second cathode follower 50 to cathode 72. The potential is also applied as a bias to the grid 29 of the cathode-ray tube 27, the connection including also a bias circuit 60-64 driven from the horizontal sweep output transformer 37.
