Title: Frequency-multiplex data transmission
Inventor: CHANG ROBERT WU-LIN
IPC: H04N21/2383
Filed: 1967-10-26
Abstract: 1,205,598. Multiplex systems. WESTERN ELECTRIC CO. Inc. 26 Oct., 1967 [14 Nov., 1966], No. 48661/67. Headings H4L and H4R. In a multiplex data transmission signal each channel signal is shaped by a shaping filter which has an amplitude frequency response having even symmetry about the centre frequency, and odd symmetry of the square of the response about frequencies midway between the centre frequencies of adjacent channels, with zero response beyond the centre frequency of the adjacent channel, and the phase/frequency characteristic differs by 90 degrees between adjacent channels. Data is fed to the channels at a transmission rate equal to twice the spacing between adjacent channels centre frequencies. The system is such that adjacent channels overlap in the frequency spectrum. The transmitted signals may be binary digits or of multilevel form derived from analogue samples. The received signals are detected by correlation techniques using matched filters. It is shown that an amplitude frequency characteristic that is a cosine function, Fig. 2(a) (not shown), or a positive half cycle of a cosine function, Fig. 2(c) (not shown), or that given by an over-coupled double-tuned circuit, Fig. 3(a) (not shown), fulfil the requirements for the shaping filters amplitude frequency response while the phase characteristic, if all the filters are to have identical characteristics, should be linear with ripple terms having odd symmetry about the mid-frequency points between adjacent channels. The filters may be adjusted to the transmission frequency of each channel or they may, as shown in Fig. 4, be identical and the outputs from the filters 44 transformed to the appropriate frequency in modulators 45 before the outputs are summed, in 47, and filtered to remove the unwanted sidebands produced in the modulation step. A synchronizing signal fs is added to the combined channel signals in summing amplifier 47 before the signal is filtered and frequency changed to the appropriate frequency band for transmission. At the receiver, Fig. 6, the incoming signal has the synchronizing signal picked off at 70 and the channels are transformed to the appropriate base-band position by modulators 74, and then filtered by 76 to produce only the wanted channel signal and the overlapping side bands of the adjacent channels. The information contained in the wanted channel is obtained by applying the output of filter 76 to a matched filter 78, which comprises a transversal equalizer adapted to have an impulse response which is the inverse of the waveform to which it is matched, and then sampling the output, at the original sampling frequency 2f8, in sampler 79.

The wax may be repulped with solvent and filtered again, the solvent being stripped from the wax and fed to the primary filtration. The rate of flow in the primary filter stage is measured and a signal is generated which controls the temperature of the solvent to the chilling stage by altering the flow of coolant to the solvent indirect heat exchanger. Examples of solvent are aliphatic ketones, benzene, toluene, low boiling petroleum hydrocarbons, chlorinated methane compounds or suitable mixtures of these. The oils to be dewaxed may be mineral, fatty acid, fish vegetable or animal oils.

Abstract: 1513649 Photographic cameras AGFA-GEVAERT AG 17 Dec 1976 [23 Dec 1975] 52811/76 Heading G2A A camera has at least two lenses, each movable between an operative and an inoperative position spaced apart laterally with respect to the optical axis of the camera, at least one of the lenses, in moving between these two positions, having also a component of movement parallel to the axis. As shown, a wide angle lens 5 and a telephoto lens 6 are mounted on a lens carrier 4, which can be moved laterally with respect to the optical axis O by means of a button 13, to bring either lens into the axis O, in which it is aligned with the picture gate 3 of the cassette 2. In Fig. 1 the lens 5 is so aligned. If the lens carrier were moved to the left, in order to bring lens 6 into alignment with the axis O, the take-up chamber 2b would interfere with the free movement of the carrier. A sloping shoulder 4a is therefore provided on the carrier, so that when this moves to the left it abuts against a guide 1a fixed to the camera. Thus the carrier is shifted parallel to axis O sufficiently for it to clear chamber 2b, as seen in Fig. 2. Fig. 3 (not shown) illustrates another method of moving the carrier clear of chamber 2b, and in Fig. 4 (not shown) the lens 5 only is so moved.
