Title: Apparatus for detecting and eliminating hum
IPC: A61B5/276
Filed: 1968-03-14
Abstract: 1,221,472. Amplifying circuits. NIHON KOHDEN KOGYO CO. Ltd. 14 March, 1968 [24 March, 1967], No. 12521/68. Heading H3W. [Also in Division G1] A system for detecting hum in a low frequency signal to be measured, such as may arise from an electrocardiogram, incorporates two similar dynomometer type devices, each being as shown in Fig. 1A, each having two magnetic circuits 10, 15 energized by a mains A.C. source 23. The sources for the two separate devices provide energizing signals which are relatively phase shifted by 90 degrees. The signal containing hum components is applied to each moving coil 11 in the magnetic circuit 10 in each device. Rotation of the shaft 20 in each device takes place due to interaction between the hum and mains signals, and an induced output signal from the coil 18 in the other magnetic circuit of each device is produced. The two output signals are combined. It is shown mathematically that this combined output signal represents hum, with all other components removed. Controlling force is provided by spiral springs 21, 22 and damping by vane 24. The two devices are used in a system for eliminating hum from a signal to be measured applied to the input 25 of an amplifier 26, by coupling them in feedback paths 28, 28<SP>1</SP> around the amplifier, the main supply being applied at 29 and phase shifted for one device at 30. The outputs of the two devices are combined to provide a signal representing hum, which is subtracted from the signal to be measured at the amplifier input.

Abstract: 1,146,463. Adducts of carbon tetrachloride and olefins. M. ASSCHER, A. KATCHALSKY, and D. VOFSI. 22 March, 1966, No. 12585/66. Addition to 1,023,423. Heading C2C. 1 : 1 Adducts of carbon tetrachloride and an olefinic compound, or alcoholysis products of such adducts, are prepared by heating carbon tetrachloride and the olefinic compound in a substantially homogeneous system in the presence of a catalyst comprising a compound of Cu or Fe, other than a chloride of Cu or Fe or cupric stearate, and, if desired, in the presence of a cosolvent for the catalyst and reactants to give a product containing one -CH 3  group and one Cl atom for each isolated double bond in the olefinic reactant and, if an alcohol cosolvent is used, to give an alcoholysis product in which the added Cl atom is replaced by an alkoxy group. Specified reactants include mono- and poly-olefins and unsaturated halides, alcohols, ethers, carboxylic acids and the nitriles, esters, chlorides, anhydrides and amides thereof, aldehydes and ketones. Reactants containing conjugated double bonds and one molecule CCl 4  per pair conjugated double bonds to give an unsaturated product. Suitable cosolvents include acetonitrile, methylene chloride, benzene and C 1-4  alcohols. If necessary, a solubilizing agent for the catalyst, preferably an alkyl ammonium halide, may be employed. Preferred catalysts are iron naphthenate, ferric acetyl acetonate and cupric acetylacetonate. An improved yield is obtained if the reaction is effected in the presence of a reducing agent, e.g. benzoin, hydroquinone, stannous chloride, aldehydes and alkali metal sulphites. Examples relate to the preparation of 1,1,1,3 - tetrachloropropane from ethylene, 1,1,1,3-tetrachlorobutane from propylene and 1,1,1,5-tetrachloropentene-(3).

Abstract: 947,884. Pulse generating circuits; controlled non-linear inductor circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 1, 1962 [April 7, 1961], No. 12592/61. Headings H3B and H3P. In a pulse generator of the type in which a charged delay line is discharged into a load via a switching device, the pulse duration is made adjustable by means of a saturable core reactor connected to a different part of the delay line and triggered so as to discharge part of the line at a time which is adjustable in dependence on the duration of the required pulse in the load. Fig. 1 shows a known circuit in which delay line 1, having a transit time T/2 is charged from a D.C. supply 2. A trigger pulse on line 3 is delayed by period T/2 before being fed to the thyratron S1 to discharge line 1 into load 10. A further thyratron S2 with an auxiliary load R is provided, the firing time being adjustable by means of a variable delay unit 7. It is shown that if the delay introduced by unit 7 is adjusted between the limits O and T the pulse duration in load 10 is adjusted between the limits O and T. Fig. 2 (not shown) relates to a similar circuit in which the thyratrons are replaced by saturable core reactors which reach saturation level at different times in dependence on adjustable current in control windings. In Fig. 3, the thyratron S3 is connected to the common point of the capacitors of line 1 (Fig. 1) whilst the second thyratron is replaced by a saturable reactor P3. The pulse duration in load 10 is dependent on the relative time of firing thyratron S3 and reactor P3, the latter being controlled by the value of variable current from source 13.

Title: Semiconductor device manufacture
IPC: H01L29/74
Filed: 1975-03-26
Abstract: 1536545 Semiconductor devices MULLARD Ltd 24 March 1976 [26 March 1975] 12649/75 Heading H1K An annular diffused p-type region 6 at least 75 microns deep is formed in a Si body 1 by depositing on the body 1 a layer of Al of 0À2-5À0 microns thickness, locally removing the layer to leave a pattern 4 including at least one annular portion, heating the body in an oxidizing atmosphere so that Al diffuses into the body 1 and a silicon oxide layer 7 forms on the rest of the body, the layer 7 serving to extract Al from the underlying body portions and transport it into the atmosphere, and removing from the body I both the oxide layer 7 and the residue of the Al layer 4. The Al layer 4 may be deposited on an alumina or silicon oxide layer on the body 1, which layer prevents alloying of the Al to the Si but does not otherwise hinder the deep diffusive process beyond merely increasing the required diffusion time. Alternatively the Al may be permitted to alloy to the Si, in which case the alloyed material is removed at the same time as the oxide 7 and the residual Al. To ensure that this removal occurs a shallow portion of the Si body underlying the alloyed material is preferably also removed. The Al layer 4 may be covered during the deep diffusion, e.g. by anodization or by deposition of silicon oxide. A similar Al deep diffusion in registration with that in the upper surface 2 may also be effected in the lower surface 8, the two opposed diffusions merging to entirely surround a portion 9 of the body 1. Alternatively an overall p-type region may be formed at the lower surface 8. The pattern 4 may be in the form of a grid, either isolating discrete device-containing islands in an integrated circuit or providing zones along which the initial wafer is ultimately subdivided. Thyristors or triacs may be formed in the isolated islands.

Title: Process for the conversion of textile vegetable fibres into threads having the texture of wool
IPC: D01C1/02
Filed: 1929-04-24
Abstract: 329,792. Maillard, F. G. April 24, 1929. Yarns &c., treating with liquids, gases, and vapours.-Vegetable fibres such as jute, hemp, &c. are converted into a wool-suhstitute by a process comprising mechanical treatment in a greasy bath, spinning the fibre and doubling, separating the ligneous from the cellulose constituents, next hydrolizing in caustic alkali, then bleaching, finishing and treating electrolytically to render the threads impermeable. In an example, hemp or jute is stacked and is left 5 to 7 days in the greasy bath which contains 7 per cent of completely saponifiable wool oil. The fibres are then passed through a carding-engine and drawing- frame, spun and doubled. The threads thus obtained are soaked in an alkaline carbonate at 60‹ C. and then at ordinary temperature for half an hour in sodium sulphoricinate to which is added 10 grams per litre of an alkaline carbonate. These treatments, which are both effected in a vacuum, produce the separation of the ligneous and cellulose constituents. The threads are then washed, and dried in a hydro-extractor. The hydrolizing is effected in a bath of caustic alkali from 18‹ to 25‹ BÚ. according to the nature of the fibres and takes about half an hour, the threads then being drained, neutralized, and washed. The bleaching comprises chloring at half a chlorometric degree followed by washing, acidifying and again washing or by passing through permanganate and bisulphite, and washing, the bleaching being completed by treatment with gaseous products of combustion of sulphur in a furnace kept at 50‹ C. The finishing is effected by impregnating the threads in a 10 per cent alkaline sulphoricinate bath. The threads are rendered impermeable by an alkaline sulphoricinate converted into aluminium sulphoricinate inside the threads by electrolysis in a bath of aluminium sulphoacetate.

Title: Method of detecting the state of fusion of the workpiece being welded
IPC: B23K9/09
Filed: 1975-03-27
Abstract: 1493524 Detecting state of fusion in a weld NATIONAL RESEARCH INSTITUTE FOR METALS 27 March 1975 [30 March 1974] 13009/75 Heading B3R In a welding process using an arc or electron beam directed to one side of the workpiece, the state of fusion of the weld is detected by detecting changes of temperature at the opposite side of the workpiece. This is achieved by superimposing on the arc or electron beam current a signal current consisting of positive and negative current pulses and/or a sinusoidal current to change the heat input to the weld at the side where the arc or electron beam has been applied, detecting the change of said heat input and the corresponding temperature change at the opposite side of the workpiece weld caused by the changes in current whereby the state of fusion of the weld is detected. The changes in temperature are detected by a photo-electric device which receives the changes in radiant heat and emits electrical pulses proportional to the temperature of the weld.
