Title: Electric wave filters
IPC: H03H9/60
Filed: 1960-10-20
Abstract: 925,547. Piezo-electric filters. CLEVITE CORPORATION. Oct. 20, 1960 [Oct. 27, 1959], No. 35950/60. Class 40 (8). A piezo-electric element for use in a wave filter comprises a piezo-electric plate having a number of electrodes on one face and. one or more counter-electrodes on the opposite face whereby different parts of the plate may be independently vibratory at different fundamental frequencies in the same thickness mode. The plate may be made from a monocrystalline material or from a polycrystalline ceramic material and is cut or electrostatically polarized to operate in a thickness mode, e.g. thickness expansion or shear mode. The plate may be circular (Fig. 12) or of any other suitable configuration, e.g. rectangular or rectangular with rounded ends. Six pairs of circular electrodes define six resonators 226a, 226b, 226c and 228a, 228b, 228c, the first three being resonant at one frequency and the last three at another frequency. Since the resonant frequency is a function of thickness, the frequency difference can be achieved by a local thickening of the plate or by a difference in electrode thickness. The resonators are connected to form a symmetrical ladder filter by means of conductive strips extending from electrode to electrode and from the electrodes to a terminal B and an earthing strip 236. Strips on the top side of the disc are indicated by continuous parallel lines, those on the other side by broken lines. In the circuit diagram of Fig. 13, the resonant L.C. circuits bear the same references as the resonators in Fig. 12. The Specification also describes a single #-section filter using three pairs of electrodes and a single L-section filter using two pairs of electrodes. In the latter, the two counter-electrodes may be replaced by a single common electrode. In all the filter circuits, the resonators in the shunt branches are arranged to have anti-resonant frequencies coinciding with the resonant frequencies of the series resonators, thus forming a band-pass filter. Specifications 688,179 and 867,039 are referred to.

Title: Improvements in the manufacture of loaded electric signalling conductors
IPC: H01B11/14
Filed: 1930-12-02
Abstract: To avoid straining the loading material during the annealing of a continuously-loaded conductor, a spacer of thermoplastic material, such as guttapercha, which vaporizes during the annealing operation is disposed between the conductor and the loading tape.  The loaded conductor may be annealed in an atmosphere of nitrogen, but preferably, to avoid the formation of soot on the walls of the annealing furnace due to the decomposition of the spacer, the annealing operation is performed in an atmosphere consisting of an inert gas, such as nitrogen, containing a gas, for example water vapour, in which there is combined oxygen capable of oxidizing the carbon present in the spacer.  The water may be introduced into the furnace in drops or in the form of steam, or water may be sprayed in with the nitrogen.  In modified arrangements, the loaded conductor may be wetted or the spacer soaked in water prior to the heat-treatment. To prevent escape of poisonous gases generated during the annealing operation, a furnace of the kind described in Specification 368,493, [Group XXXVI], may be employed, or the gases may be ignited as they issue from the furnace. Specification 282,504, [Class 36, Electricity, Conducting &c.], also is referred to.

Title: Data transmission systems
IPC: H04L25/03
Filed: 1964-09-07
Abstract: 1,017,150. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 7, 1964 [Sept. 30, 1963], No. 36633/64. Heading H4P. In a data transmission system in which the transmission channel subjects the data pulses to linear distortion the receiver includes an arrangement for eliminating the distortion, the arrangement being set up by low-speed test pulses sent prior to the high-speed data. As a result of the distortion, each pulse becomes a waveform having a main peak and a number of lesser peaks. The receiver samples the main peak and one or more other parts of the waveform, and by the use of attenuators adds part of the peak sample to each of the other samples such that the result of each addition is zero. The test pulses 11, 12 are transmitted at such a spacing that the corresponding received waveforms 16, 17 do not overlap. Each received signal is fed to a delay line 20, to main peak detector 70 which causes clock 71 to shift a pulse from A to E in register 72 at the highspeed bit rate, and via summing circuit 50 which receives the attenuator outputs to the receiver output terminal. Delay 20 is tapped at intervals corresponding to the reciprocal of the bit rate. Comparator 120 is enabled each time there are outputs on the corresponding terminals of register 72 and counter 61. Thus, as counter 61 is in position A initially, the comparator is enabled at the same time that attenuator 42 is enabled. The inputs to the comparator are zero potential and the output of the summing circuit. The comparator output feeds unit 60 which controls the setting of the enabled attenuator, 42 in this case. Successive received signals cause unit 60 to control a sequence of switchings in the attenuator whereby the sum of the attenuator output and of the portion of the waveform currently at terminal 21 is reduced to zero. At the end of the sequence of switchings unit 60 sets counter 61 to position B, and the operations are repeated for the setting of attenuator 43. When all the attenuators have been set, a test pulse will provide a pulse at the receiver output when the main peak arrives and at no other sampling instant. When the high-speed data is received the distorted waveforms will overlap, but since the sampling rate is also the bit rate and because of the settings of the attenuators, the effects of the overlapping are cancelled and a pulse appears at the receiver output for each pulse transmitted.
