Title: Improved wired broadcasting systems and apparatus therefor
Inventor: GARGINI ERIC JOHN
IPC: H04N7/10
Filed: 1962-04-13
Abstract: 1,045,872. Television distribution systems. COMMUNICATIONS PATENTS Ltd. May 10, 1963 [April 13, 1962], No. 14325/62. Headng H4R. In a colour television distribution system comprising at least two paths each of which carries at least one television transmission, the signals applied to each path comprise a modulated carrier wave, brightness information signal and a suppressed-carrier colour information signal, it being arranged that for each colour signal present in one path there is available in another path a brightness signal the carrier frequency of which is equal to the suppressed carrier wave of the colour signal, whereby at a receiver, the transmitted carrier wave can be used as a re-insertion carrier for demodulating the colour information signal. In the two programme system described, carrier frequencies f 1  and f 2  are supplied by oscillators 1 and 2 to the modulators 3, 4 and 5, 6 respectively. The brightness and colour signals of one programme are modulated on to the carriers f 1  and f 2  at 3 and 5 respectively to provide a modulated carrier wave brightness information signal 22 (Fig. 2) and a doublesideband suppressed-carrier colour information signal 23 while the brightness and colour signals of the other programme are modulated at 6 and 4 on to carriers f 2  and f 1  respectively to provide corresponding information signals 25 and 26. The information signals are combined in the appropriate mixing circuits 11 and 14 and supplied to the two signal paths 12, 13 and 15, 16 respectively of the distribution system. At a receiver (Fig. 3) the colour and brightness information signals on one of the paths are passed via a broad band amplifier 30 to a (colour signal) band-pass filter 32 and a (brightness signal) detector 31, while the brightness signal carrier frequency of the remaining path is selected by a narrow bandpass filter 37 and passed via an amplitude limiter 39 to a phase-shift network 40. The phase advanced and retarded signals provided by the network 40 are then supplied to demodulators 36 and 35 so as to demodulate the upper and lower sidebands of the colour information signal supplied by filter 32. The resultant signals are processed in matrix 34 and used to control a colour television picture tube 44. In an alternative embodiment one path of the system is used to carry a plurality of brightness information signals while another path carries all the corresponding colour information signals. In a further alternative the brightness and colour information signals pertaining to one programme are transmitted over different paths, the carrier frequency of a brightness signal being used to demodulate the corresponding colour information signal. The filters 32, 37 and 40 are coupled to programme selection switch 29 so that their components may be suitably altered in accordance with the frequencies used for the particular programme required. Reference has been directed by the Comptroller to Specification 768,682.

Title: Fluid heating
IPC: F28C3/14
Filed: 1945-06-07
Abstract: 630,549. Furnaces. BABCOCK & WILCOX CO. June 7, 1945, No. 14379. Convention date, July 4, 1944. [Class 51 (ii)] [Also in Group XIII] In a " pebble " heater unit (see Group XIII) in which gaseous fluid is heated e.g. to temperatures above 1650 C., by a fluent mass of refractory solid material which moves through superposed chambers 12, 13 in which it is heated by combustion gases and cooled by passing the fluid in contact with the fluent mass in the cooling zone, part of the heated fluid takes part in combustion with a further gaseous fluid, the combustion products passing through and heating the solid material in the heating zone, and the remainder of the heated fluid is taken off for external use. If air is heated in the lower chamber 13, part of it can be passed through ducts 69, 82, Fig. 6 to a furnace needing a high-temperature oxidising atmosphere, e.g. a continuous tunnel kiln 80 for the glazefiring of ceramic ware at 985 C. The heated air passes at one end of the kiln into longitudinal side chambers 83 and through the perforated walls 84, and is withdrawn at the other end through ducts 85 by a fan 87 which returns it through a pipe 89 to the chamber 13, where it is re-heated. The combustion gas is preheated in the preheater 88. If fuel gas is heated in the heater of Fig. 6, part of it may be used in a furnace needing a high-temperature reducing atmosphere, e.g. a furnace, Fig. 8, used for the bright annealing of copper sheets 104. The hot gas enters this furnace at the bottom at one end through a pipe 97, and after flowing over the-stack of copper sheets passes out at the sides through passages 108 and outlets 98 back to the lower chamber 13 of the gas heater. The returning gas may preheat the air for combustion in the heater, and part of it may be bled off. The upper part 95 of this annealing furnace is removable for charging, and has a sand or liquid seal 96 with the fixed base 94. After charging and before supplying the hot gas, cold fuel gas is supplied t o the furnace to drive out air through a vent pipe 106. Specification 628,321, [Group XIII], is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of all or part of the air or gas, heated in the lower chamber of a pebble heater, in a high-temperature industrial process, and passing the combustion gases resulting from its combustion with complementary gas or air, either in a process furnace or a combustion chamber to the upper chamber of the pebble heater to heat the fluent mass. For example, air heated in the pebble heater is supplied to a gaseous or liquid fuel burner mounted in a melting pot, from which the hot gases pass to an annular chamber surrounding an opening into the lower part of the upper chamber of the pebble heater. This subject-matter does not appear in the Specification as accepted.

Title: Recording by Particle Orientation.
IPC: G03G5/022
Filed: 1967-03-29
Abstract: 1,188,982. Electro-photographic processes. RANK XEROX Ltd. March 29, 1967 [April 4, 1966], No.14412/67. Heading G2H. A reusable imaging member 10 comprises a thermoplastic sheet 11, Fig. 1, which receives a latent electrostatic image and a dispersion of non-ferro magnetic particles 12 embedded in the sheet, the particles aligning with the electrostatic field set up by the charge image in accordance with the intensity of the field when the sheet is heated to a softened condition. The particles are diamagnetically anisotropic such that they have increased diamagnetic susceptibility in one direction, whereby erasure of the image may be effected through application of magnetic fields normal to the one direction while the sheet is in softened condition. In use, the particles 12 which may be of colloidal graphite, antimony, bismuth, napthalene, anthracene, or p-terphenyl align with the electrostatic field set up by the charge pattern of the image. In one embodiment, Fig. 2a, the member 10 includes a photo-conductive sheet 14 contacting the sheet 11. The sheet 14 has a transparent conductive sheet 15<SP>1</SP> mounted on a support sheet 15. Information 20 to be recorded is projected through a lens 21 and focused on the sheet 14 while applying a potential across the member. The sheet 11 receives a surface charge pattern which is retained upon separation from the sheet 1.4. Alternatively, an electron beam (16) Fig. 2b (not shown) produces the latent electrostatic image. In each case the sheet (11) Fig.3 (not shown) is heated to softened condition by a heater (23), such that the electrostatic field causes the particles (12) to form a pattern of angles corresponding to the information to be recorded. The image may be read by magnetic reading means which sense variations in magnetic reluctance after forming a magnetic field by poles (24) Fig. 4 (not shown). Other methods of reading include measuring the remanent magnetic field after passage through a uniform magnetic field, sensing by a photo-cell the light transmitted through the layer, or sensing variations of conductance or capacitance. Erasure of the image is achieved by passing the sheet 11 over a heated roller (25) Fig.5 (not shown) and beneath magnetic poles (26) which apply a magnetic field to realign the particles 12, Fig. 1, longitudinally of the sheet.

Title: System for conveying sound information to the brain
IPC: H04R25/00
Filed: 1973-03-27
Abstract: 1402508 Hearing aids ZCM Ltd 27 March 1973 14719/73 Heading H4J [Also in Division A5] In a hearing system in which sound signals are converted into pulses whose width corresponds to the signal frequency and whose amplitude corresponds to the signal amplitude, the pulses are modulated on to a carrier which is also amplitude modulated by the original signal. Compared with the system disclosed in Specification 1,284,158, the additional modulation increases the modulation depth of the carrier from less than 5% to between 20 and 50% whereby an enhanced sensation of hearing particularly at high frequencies is obtained. The carrier frequency may be in the range 60 to 100 kHz or in the microwave range of 1000 MHz. In the latter case, the electrode system used for conveying signals to the user's body consists in a ring 78 connected to a coaxial cable outer 70 and spaced in insulating manner from a central disc 74 connected to the cable inner. The disc and possibly also the ring are covered in insulating material. The electrodes may be held against the user's neck with the aid of a strap (Figs. 3, 5, not shown). Alternatively the electrode structure may be held against the ear manually (Fig. 7, not shown), with headphones (Fig. 10, not shown) in which case stereophonic operation could be obtained, or with the assistance of a telephone handset (Figs. 8, 9, not shown). In order to maximize coupling of the aid to the ear, a highly-flexible fluid-filled bag may be interposed therebetween (Fig. 11, not shown). The outer portions of the ear may be folded over the ear channel prior to placement of the aid. Circuit comprises between two and ten trigger circuits 16-18 each having a different threshold. Their outputs are relatively delayed and then added and shaped in device 20 so as to produce an output whose pulse repetition rate corresponds to the amplitude of a sound impinging on microphone 10 and whose pulse width is related to the frequency of the sound. The input signal is also applied via control device 7 to the pulse signal so as to modulate it (waveform 24A) prior to modulation on to a high frequency carrier (waveform 28A). The output is taken from electrodes 30 which are connected to one side only of output transformer 29. It is suggested that the amplitude modulation causes a ripple of the basilas membrane of the cochlear duct such that the accompanying pulses may penetrate and cause nerve firing even in the absence of cochlear hairs or positive nerve action.
