Title: Improvements in or relating to delay cells
Inventor: MORTLEY WILFRED SINDEN
IPC: H03H9/44
Filed: 1964-11-30
Abstract: 1,096,241. Electromechanical delay lines. MARCONI CO. Ltd. Oct. 19, 1965 [Nov. 30, 1964], No. 48506/64. Heading H3U. A dispersive delay cell comprises a body of wave propagating material and input signal means for propagating within the body waves of different frequencies in different frequencydependent directions, the waves being directed by a reflector to output signal means, the arrangement being such that the wave path lengths between the input and output means via the reflector are different for different frequencies so that the waves of different frequencies are delayed by different times. As shown, Fig. 2, a block of quartz 1 has input means 3 and output means 4 constituting transducers formed by stuck-on thin slips of quartz provided with conductive gratings, the gratings of means 3 extending at right angles to the gratings of means 4 (Fig. 1, not shown). Alternatively, the block 1 is a piezo-electric crystal and has the conductive gratings formed thereon. The reflector 5 is constituted by a surface along one edge of the block formed at 45 degrees to the adjacent surfaces and having a graduated grating formed by lines extending at right angles to the length of the edge. The graduated spacing of the lines shown in Fig. 2 is only diagrammatic, the lines being too closely spaced to be shown correctly in the drawing. The spacing of the grating lines of the input means 3 is such that a signal of any given frequency produces a beam subtending an angle # corresponding to that frequency, that beam after travelling along a path having a length l arriving at the reflector 5. From the reflector, the beam is directed out of the plane of Fig. 2 to travel along a path of length h to the output means 4. The spacing of the grating lines of the reflector 5 at any point is arranged to be appropriate to the frequency of the beam arriving at that point so that the beam is reflected. The Specification describes the underlying theory. Unwanted wave energy is absorbed by coating all surfaces of the block 1 not occupied by gratings with solder, pitch or metal loaded resinous material. Reference has been directed by the Comptroller to Specification 998,102.

IPC: B01J19/00
Filed: 1962-12-27
Abstract: Epichlorohydrin is added to a mixture of hydrochloric acid and aqueous trimethylamine at 55 DEG  F. in a stainless steel reactor. After stirring for about 20 minutes, the reaction mixture is evaporated continuously through an evaporator at 60 p.s.i. steam pressure to a moisture level of 12% to yield 2,3-epoxypropyltrimethylammonium chloride (66.7%); 3 - chloro - 2 - hydroxypropyltrimethylammonium chloride (11.1%) and 2,3-dihydroxy-propyl-trimethyl ammonium chloride (7.8%).ALSO:A process for flocculating materials suspended in aqueous systems comprises adding to the system a flocculating agent comprising a quaternary ammonium starch ether prepared by etherifying granular starch in contact with an alkaline catalyst with the reaction product of an epihalohydron and a tertiary amine, or salt thereof, of formula <FORM:1030410/C3/1> where R1, R2 and R3 are alkyl, substituted alkyl, aryl or aralkyl, the total number of carbon atoms being less than 14, the quaternary ammonium starch ether being gelatinized before use and having a Scott viscosity of 5 g./50-80 seconds to 75 g./50-80 seconds per 100 ml. of delivered paste. Any two of R1, R2 and R3 may be joined on a heterocyclic ring.  Many amines are specified.  The necessary viscosity of the starch ether may be achieved by any viscosity-reducing treatment, e.g. hydrolysis, oxidation, methanucal stear or cooking, which permits the starch to remain in granule form. Viscosity-reduction may be carried out prior to or after etherification, which may be effected by dissolving the epihalohydron-amine reaction product in water, dioxane or isopropyl alcohol, and adding starch and catalyst, e.g. NaOH. Reaction occurs at room temperature.  A salt, e.g. NaCl, Na2CO3, MgSO4 or Na2SO4, may be added to raise the gelatinization temperature of the starch.  In an example, a quaternary ammonium ether of D.S. 0.038, made by reacting granular corn starch with the reaction product of trimethylamine and epichlorohydrin, is depolymerized by heating with aqueous HCl at 40 DEG  C., to a Scott viscosity of 7 g./50 seconds per 100 ml. of paste.  The product is used to flocculate an aqueous suspension of calcium carbonate.  The starch ethers may also be used as calcium carbonate retention aids in paper-making.ALSO:Quaternary ammonium starch ethers having a Scott viscosity of 5g/50-80 seconds to 75g/50-80 seconds for 100 ml of delivered paste are used as pigment retention aids in paper manufacture. The starch ethers, made by treating granular starch with the reaction product of epihalohydrin and a tertiary amine containing less than 14 carbon atoms, are gelatinised before use.  In example, the quaternary ammonium starch ethers are added to sulphite or sulphate pulp containing calcium carbonate or titanium dioxide, and the pigment retention of hand sheets is measured.

Abstract: 1396987 Forming diamond by sputtering V M GOLYANOV and A P DEMIDOV 23 Oct 1972 [28 Oct 1971] 48657/72 Heading C1A [Also in Division C7] Diamond is said to be produced by sputtering graphite simultaneously from a plurality of graphite electrodes in an electric discharge chamber which contains a noble gas atmosphere at reduced pressure, the cathodes being arranged so that the carbon atoms emitted by the cathodes impinge on a substrate which is common to them all. A vessel 1, may be evacuated by pipe 2 before a noble gas, preferably krypton, is introduced therein. Inside the vessel are disc graphite cathodes 3 having between them annular metal anode 4, all being attached to D.C. source 5. A holder 6 supports a substrate 7 which is stable under the conditions used; and on to which the carbon atoms formed during sputtering are deposited. The vessel 1 and its contents preferably are placed into a Dewar flask 8 filled, during operation, with liquid nitrogen, e.g. the substrate during use is usually maintained at - 196‹ C., and the vessel may be arranged inside a solenoid 9 which provides a magnetic field the direction of whose lines of force coincides with the discharge initiated between the electrodes. During use the vessel is pumped down and degassed, e.g. by heating, liquid nitrogen is admitted to the vessel 8, the magnetic field is operated, and Krypton is admitted to give a pressure of no more than 10<SP>-4</SP> torr and preferably between 10<SP>-4</SP> and 10<SP>-7</SP> torr. A 4 KV D.C. voltage is then applied and the carbon atoms so formed are deposited on substrate 7 as a diamond layer. If the cathodes contain an element of Group III of the Periodic Table according to Mendeleev, a semi-conductive diamond of a P-type conductivity is obtained, and if an element from Group V of this Periodic Table is used a semi-conductive diamond of N-type conductivity is formed. The substrate may be subsequently dissolved in a chemical reagent to give a free diamond film.

Patent GB-501334-A (GB)
Abstract: 501,334. Filters; purifying water. DESROCHES, E. J. May 18, 1937, No. 13803. [Class 46] Water is filtered through textile material on which a membrane has been formed by causing the cloth to adsorb an inorganic substance, such as hydroxide of aluminium or iron, which forms a colloid with water. Superposed membranes of different colloids or a membrane formed of mixed colloids may be used. To obtain the colloid a natural earth, for example bauxite, may be suspended in water to which a decoagulant is added to assist the separation of impurities. A coagulant is then added, and the water containing the colloid is passed through the filter so that the membrane is formed on the cloth. An auxiliary membrane of cellulose, powdered coal or charcoal, or natural silica may be superposed on the colloid membrane. The water, prior to filtration, may be treated with aluminates, silicates, ferric hydrate or other powders or colloidal solutions. The plant shown in Fig. 1 comprises a filter 40 in which bags 51 are suspended from apertures in a plate 48. The support for each bag may comprise a short tube 50, Fig. 4, and a member 55 connected to the tube by rods 56. Water containing the colloid is supplied to the filter from a receptacle 65 through pipes 68, 71, the colloid being deposited on the bags and the water passing away through a pipe 68. The water to be treated is supplied through a channel 1 fitted with pipes 4, perforated at the upper part and surrounded with cloth, through which air is supplied under pressure. Reagents are supplied from delivery apparatus 6. After passing through settling apparatus (not shown) the liquid enters the filter through a pipe 39 and is distributed therein by a deflecting ring 72, Fig. 4, and a perforated plate 73. The filter bags may be filled with fine gravel to retain their shape. The upper space 57 of the filter may be charged with active carbon or other adsorbent material. Other materials for the treatment of the filtered water may be supplied through a device 74. Fig. 5 shows a modified form of filter element in which the cloth 93 is supported on wire 106 wound on a metal framework 103 connecting a tube 92 with a core 98 which is fixed in a plate 100. A domestic filter, Fig. 6, has a filter bag 111, supported between casing sections 107, 108, with inlet controlled by a ball valve 119 and outlet pipe controlled by valve 115 and provided with a cap 116. In the filter shown in Fig. 7, colloid in powder form, sometimes mixed with powdered coal or carbon, is initially placed in a paper envelope 125 between cloth discs 123, 124. It is stated that when water is passed through a colloidal membrane -is formed on the cloth. Fig. 8 shows decanting apparatus with baffles 145 which has been converted for use in application of the process of the invention by fitting filter bags 147 to a partition 146. The colloid membrane is formed on the inner surface of the bags. A cable may be attached inside at the end of each bag, so that the bag can be drawn inside-out for cleansing.
