Title: Staircase waveform signal generator
IPC: H03K4/02
Filed: 1975-04-18
Abstract: 1475819 Staircase waveform generator COM. PAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 18 April 1975 [24 April 1974] 16043/75 Heading H3T In a staircase waveform generator a capacitor 2 is charged from a source 40 via a switch 4, the capacitor forming part of an integrator 1, 2, 3 the output of which is A.C. coupled via a capacitor 12 to a comparator 5 which compares changes in the integrator output with a reference. The output of comparator 5 is used to control the switch 4. The capacitor 2 is discharged by further switch 16 under control of signals at 17. As described, at the beginning of each staircase wave, transistor 4 is conductive so that capacitor 2 charges comparatively rapidly until the comparator 5 changes state, when transistor 4 is turned off. The output 30 then remains at its step value until capacitor 12 discharges sufficiently via resistor 11 to reset comparator 5 so that transistor 4 is again turned on. This sequence is repeated so that a staircase wave is generated at 30 until capacitor 2 is discharged by a pulse at 17 which turns on transistor 16. The time constant 11, 12 should be considerably greater than the effective time constant 1, 2.

Filed: 1972-04-07
Abstract: 1389325 Doping semiconductors SEMIKRON GES FUR GLEICHRICHTERBAU UND ELEKTRONIK mbH 7 April 1972 [8 April 1971] 16059/72 Heading H1K A dopant source for spraying or spin-coating on to a semiconductor body, preferably Si, comprises a boron compound, an organic compound or oxide of a semiconductor element, preferably Si, a metal compound, and a solvent/carrierliquid. After application of the source material, the coated body is heated to evaporate the solvent/carrier-liquid and to form a glass from the other components and effect diffusion, the metal chosen so as to produce a glass with an expansion coefficient close to that of the body. This is particularly necessary when an opposite face of the body is coated with phosphosilicate glass. Suitable metals are nickel, lead, calcium, and tin. They may be used as acetates (which may be dissolved in acetic acid). Suitable silicon compounds are TEOS and silica. When TEOS is used lactic acid may be included in the source so that the TEOS cross-links at room temperature and the source coating is so firm that wafers may be stacked upon one another in the diffusion chamber. To avoid reduction of carrier lifetime, the source should not contain halogen-containing silicon compounds or iron, gold, copper, zinc or manganese. The boron compound may be the trioxide. Suitable solvents are ethylene glycol monomethyl ether, and ethylene glycol; ethyl alcohol may be added to enhance wetting of the semiconductor body.

Title: A frequency-modulation echo-sounder
Inventor: TUCKER DAVID GORDON
IPC: G01S15/34
Filed: 1959-05-12
Abstract: 887,622. Echo-sounders. NATIONAL RESEARCH DEVELOPMENT CORPORATION, May 12, 1960 [May 12, 1959], No. 16158/59. Class 40(7). In a fish-finding echo-sounder utilizing a frequency-modulated transmission, beat signals are derived between sea bed and nearby object echo signals. Fish lying within a few feet of the sea beds are thus differentiated from the latter. The difference-frequency output of frequency-changer 6 after equalizing in unit 8, (see also Fig. 3 not shown), to compensate for increasing echo attenuation with depth, is detected in unit 10 the output of which comprises a D.C. component corresponding to the sea bed echo and a beat frequency between that echo and a nearby fish echo; the beat frequency output is translated by mixer 12 to the audio-frequency range at which the ear is most sensitive and fed to loud-speaker 16. The apparatus inherently eliminates the effect of variations in sea depth and the ship's vertical motion. The frequencymodulation sweep period is selectable for different depth ranges. A spectrum analyzer 20 feeding a recorder or cathode-ray tube display 21 is provided. The sea bed echo signal may be fed to the loud-speaker and further recording or display apparatus via mixer 18.

Title: Improvements relating to the braking of vehicles
IPC: B60G17/027
Filed: 1962-04-27
Abstract: 957,878. Fluid pressure brakes. DAIMLERBENZ A.G. April 27, 1962 [May 3, 1961], No. 16210/62. Heading F2F. [Also in Division B7] In a vehicle braking system in which the braking force is distributed in dependence upon the loading between the several wheels or axles, abutments for suspension springs 3 associated with the wheels or axles are each constituted by one arm 4 of a two-armed lever 5 which is pivotally mounted at 6 on a frame member 7 of the vehicle and of which the other arm 10 controls a pressure regulating valve 15 whose regulated pressure exerts a counterbalancing force upon the two-armed lever 5 by way of a bellows 11 filled with a pressure medium, such as compressed air, from a source of supply via a pipe 13, so that a pressure dependent upon the wheel or axle loading is produced in the bellows. The regulating valve 15 distributes braking pressure via pipe 22 to the wheels or axles. Both the lever 5 and a crank 17 controlling the valve means 15 are normally in the mean position shown wherein a rubber bush 21 surrounding a stop 19 maintains light contact with opposite walls of an eye 20 in the lever 5. In the event of a deviation from this mean position, due to turning of the lever 5, the valve is opened either to admit pressure medium from the pipe 13 to the bellows 11 or to permit its discharge by way of a pipe 14, so that the arm 10 is brought back to its mean position. The lever arm 4 is inclined at an angle γ to the horizontal, whose tangent is equal to the constant ratio between the additional dynamic force in the vertical direction which occurs during travel and the horizontal propulsive force. By the above means only the static wheel or axle loading is effective and the influence of dynamic forces occurring during travel is avoided.

Abstract: 1460735 Utilizing dust-laden gases from coke ovens SIMON-CARVES Ltd 22 March 1974 [5 April 1973] 16240/73 Heading C5E Dust-laden gases emitted from a coking oven are collected using means, duct 14, which enable the oven chamber 10 to be connected selectively and exclusively to one of at least one pair of separate gas collecting mains 12, 13 via an ascension pipe 11, 11a, the means being operated sequentially to transfer dust-laden gases emitted from the chamber to the first of a pair of mains during and for a selected period following the charging of the chamber with coal to be carbonized, and relatively dust-free gases to the second of the pair of mains for the remainder of a carbonizing period, the dustladen gases being transferred from the first main to, and burned as fuel in, the combustion chamber 24 of a heat exchanger for drying and pre-heating coal to be subsequently carbonized. The gases are initially fed via line 22 to a first combustion chamber 24 of the heat exchanger. The gases are burned with an excess of air suplied via line 37, the combustion products including residual air being passed to a second combustion chamber 31 where substantially dust-free gas supplied via line 33 is mixed therewith for combustion to remove the residual air, and the final combustion products are passed into coal preheating chamber 38 of the heat exchanger. The gases are cooled during transfer to the collecting main, e.g. by providing liquor sprays in duct 14, and the condensate is passed via line 27 from the mains to means, e.g. settling tank 28, for separating relatively clean liquor which may be supplied via line 16 to the sprays. In the absence of sufficient dust-laden gas, dustfree gas is supplied via line 34 and valve 35 to be mixed with dust-laden gas in the first combustion chamber. A fan 23 may be included in line 22 and is associated with by-pass valve 25 connected via line 26 with main 13 so that the valve operates in response to changes in pressure of the gases in main 13 thus controlling the pressure in the main. A pair of mains 12, 13 are connected to duct 14 by associated liquorseal valves 12a, 13a, one of which opens as the other closes, so that dust-laden gas passes into mains 13 during charging and selected period, and thereafter into mains 12. Mains 12 is connected via line 17 to a by-product plant and via line 18 to settling tank 19 for the drainage of condensate and separation of relatively clear liquor which is drawn off via pump 20 to feed line 16 via line 21.
