Title: Improvements in or relating to pulse generator and modulator systems
IPC: H03K5/04
Filed: 1946-01-02
Abstract: 608,257. Pulse modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 2, 1946, No. 192. Convention date, Jan. 8, 1944. [Class 40 (v)] In a frequency-modulated pulse generator, the outputs of two oscillators of different frequencies, one of which is frequency modulated, beat together to produce a variable frequency which controls a pulse generator. As shown, a push-pull reactance valve circuit 2 varies the frequency of an oscillator 3 in accordance with a modulating signal. The frequencymodulated output is applied through a buffer valve 4 and a band-pass transformer to a mixer 5, together with the output of a variable oscillator 6, calibrated according to the beat frequency. The output of mixer 5 is applied through a low-pass filter 7 and coupling valve 8 to control a multivibrator 9 which produces square pulses of 50 per cent length at a rate depending on the beat frequency produced in mixer 5. These pulses are differentiated at 10 and the resulting short pulses applied to limiter 11, normally conducting, which passes positive pulses to the grid of power amplifier 12, normally cut off, thus producing short, square, negative pulses in the anode circuit. These pulses pass through transformer 13 to provide short positive pulses at jack 32, negative pulses in the transformer output being removed by rectifier 33. The short positive pulses appearing at the jack 32 may be used to control a radio-frequency oscillator.

Abstract: 939,535. Viscometers. TECHNE (CAMBRIDGE) Ltd. March 20, 1962 [Jan. 3, 1961; June 8, 1961; Jan. 15, 1962], Nos. 255/61, 20795/61 and 1450/62. Class 106 (2). In a viscometer of the type where the liquid under test is forced through a capillary tube 1 by a constant pressure applied to the liquid either directly or through the medium of a gas by a piston 11 mvoing in a cylinder 12. A diaphragm 15 sensitive to the pressure the piston 11 is exerting on the liquid or gas carries a rod 16 held by a flexible member 18 so that changes in pressure acting on the piston move rod 16 towards or away from a jet 19 connected to a servo system to maintain the pressure on the piston at a constant value. Means are provided, Fig. 5 (not shown), to compensate for temperature variations. The time taken for the piston to drop a predetermined distance can be measured and recorded by means of contacts on arms 55, 56 and the piston may be raised and lowered automatically by means of contacts. The first Provisional Specification discloses a capillary, through which the liquid is forced by movement of the piston formed as a helical groove in the peripheral surface of the piston or alternatively extending lengthwise through the piston. The second Provisional Specification discloses a similar capillary formed between two interfitting parts which constitute the piston. Specification 894,749 also is referred to.

Title: Improvements in the treatment of natural cellulose fabrics
IPC: D06M15/39
Filed: 1960-01-06
Abstract: Natural cellulose fabrics, e.g. cotton, are creaseproofed by partially methylenating them so that they contain an average of one methylane crosslink for every 10-200 glucose residues, treating them with caustic soda solutions of at least 45 DEG  TW for a time sufficient to cause decrystallization of the cellulose crystallites, removing the caustic within 60 seconds before appreciable fibre deconvolution occurs, impregnating them with a water soluble heat hardenable resin precondensate, e.g. a dimethylol triazane or ketane aldehyde precondensate, and fixing the resin in the fabric in the presence of a curing catalyst.  In the methylenation reaction cross links of the formula <FORM:0945040/D1-D2/1> in which R represents a hydrogenation, an alkyl or substituted alkyl chain of no more than 5 carbon atoms or a cyclic substituent, are formed in the cellulose preferably by using as methylenating agent formaldehyde, glyoxal, acetaldehyde, chloral, benzoldehyde or furfural.  The methylenating reaction may be catalysed by the use of a two component catalyst system, one component of which is an organic or inorganic acid or acid anhydride, e.g. maleic, tartaric, citric, hydrochloric, phospheric, itaconic or succinic acid, the other component being an acid salt of the Lewis acid type, e.g. aluminium chloride, strontium nitrate, tin chloride, zinc nitrate, aluminium acetate, magnesium nitrate, zirconium oxychloride or sodium bisulphate. The methylenating agent and catalyst may be applied from the same or different aqueous solutions which may also contain tinting agents, wetting agents, softeners and volatility inhibitors, e.g. isopropyl alcohol, and the fabric may then be dried and cured by heating. After impregnation with the solution of the heat hardenable resin precondensate the fabric may be subjected to mechanical treatments, e.g. calendering, pleating and compressive shrinking, prior to curing by heating, preferably using zinc nitrate hexahydrate as curing catalyst.

IPC: H01J9/14
Filed: 1970-01-06
Abstract: 1,260,271. Electro-plating. BUCKBEEMEARS CO. Jan.6, 1970 [June 30, 1969], No.602/70. Heading C7B. Apparatus for controllably reducing the diameter of the apertures of a preformed mask, to allow the mask to be used as a pattern for laying a phosphorescent dot pattern for colour television tubes, comprises a cleaning station and a station for electrolytically depositing a layer of filler material such as zinc on the surface of the masks, together with transporting means between the stations and means at the second station for dislodging bubbles of gas from the mask and for removing evolved gases from the upper region of the plating tank. In the embodiment described the masks are mounted on a conveyer with provision for raising and lowering them from and into treatment tanks. The masks are passed successively through tanks in which they are cleaned by hot alkali, derusted by nitric acid, dipped in cyanide, dried, flask-plated with copper, plated with zinc, dried, cooled and inspected, with intervening spray rinsing tanks as necessary. In the zinc plating tank the masks are given a lateral to and fro movement to assist in dislodging gas bubbles, and are given a rotation through 180 degrees to ensure evenness of plating. In the plating tank shown in Fig.3 the masks move past a number of anode holders 42 each containing a set of zinc spheres 40. Shields 41 flare outwardly towards the masks to direct zinc ions in solution evenly over the faces of the masks. The anode holders are pivotally mounted to allow control over the evenness of plating. Plating solution enters through orifices 72, 73 and is withdrawn through orifices 70, 71 for filtering, control of temperature and pH, before being returned. The atmosphere over the solution is renewed by exhaust ducts 51, 52.

A medicative inhalent solution is contained within an hermetically sealed capsule adapted when placed in hot water to release the solution which by virtue of its content of an organic saponaceous emulsifying agent produced by the interaction of an amine and a fatty acid becomes distributed as an oil-in-water emulsion of fine particle size. The solution may comprise aromatic essential oils (pine needle, citronella, terebene) and methyl salicylate in which menthol, camphor and chlorocresols are dissolved. Parachlorphenol may be employed instead of the chlorocresols. The emulsifying agent may consist of triethanolamine and oleic acid, but other amines such as aminoglycol together with suitable fatty acids may be used. The solution may also contain coupling and stabilizing agents such as a polyhydric alcohol, e.g. propanediol-1,2, or a polyethylene glycol. The solution may be enclosed in a gelatinous membrane by known moulding methods.
