Title: Improvements in or relating to the manufacture of alklai metal addition products of aromatic hydrocarbons
IPC: C07C51/15
Filed: 1934-06-26
Abstract: Alkali metal addition compounds of aromatic hydrocarbons of the naphthalene series are obtained by treating the hydrocarbon with the metal at -80 to + 50 DEG  C. in presence of a polyether, or mixture of polyethers as solvent, with a further diluent if desired. According to examples, sodium is reacted with naphthalene in dimethylethylene glycol ether, diethyl ethylene glycol ether, methylal, ethylene glycol methylethyl, methylbutyl, dibutyl and butylauryl ethers, trimethylene glycol dimethyl ether, glycerol trimethyl ether, glycerol dimethyl ethyl ether, methyl and ethyl orthoformate, methyl ethyl carbinol, the formaldehyde derivative of glycol monomethyl ether, dioxane, glycol formal, methyl glycerol formal, and dimethylene pentaerythrite; further, potassium may be reached with naphthalene, a -methyl- and b -methyl-naphthalene, in dimethyl glycol ether, and lithium and sodium likewise in the same solvent; the formation of the product is shown by a green coloration and in the case of sodium and naphthalene it is largely the 1 : 4 addition product.  Further polyethers specified include 1 : 2- and 1 : 3- propylene glycol, and further solvents which may be admixed with the polyethers include higher monoethers, hydrocarbons and alkyl sulphides, up to specified maximum concentrations.  The alkali metal addition products yield hydrogenated hydrocarbons on treatment with water of alcohol.

Title: Improvements in or relating to the manufacture of condensation products from formaldehyde and urea, thio-urea or their derivatives
IPC: C08G12/12
Filed: 1923-07-23
Abstract: In the manufacture of condensation products from formaldehyde and urea, thiourea or their derivatives with or without a condensing agent, the concentration of the hydrogen ions in the liquid intermediate product is adjusted to a value between 10-7 and 10-5 by the addition of strong or weak bases or salts exercising a basic action before proceeding to the hardening treatment.  The amount of added base is in excess of that required to fix any free formaldehyde present.  According to the examples, (1) urea is condensed with formaldehyde solution in the presence of hexamethylenetetramine as far as the formation of the initial product, which is concentrated in vacuo after adding sodium acetate to prevent premature gelatinisation; urea is then added to bind the free formaldehyde; the acidity is next determined by titration and the calculated amount of melamine or urea is added to effect neutralisation and finally the product is hardened in a mould by heat treatment; (2) urea is condensed with formaldehyde solution in the absence of a condensing agent; urea and pyridine are then added to the concentrated initial condensation product; the material becomes cloudy on hardening. Specifications 157,416, 171,094, 181,014, and 193,420, are referred to.  The Specification, as open to inspection under Sect. 91 (3) (a) describes also how the formation of cloudiness in the hardened material is controlled or prevented by the addition of "saltlike" electrolytes, the activity of which in this connection is stated to follow the sequence of Hofmeister's ion series, and includes examples in which sodium chloride, calcium chloride, sodium salicylate or potassium iodide is added to the product before hardening in order to effect clarification.  This subject-matter does not appear in the Specification as accepted.

Filed: 1966-04-29
Abstract: 1,137,775. Heating air by waste gases. H. VON AULOCK. 29 April, 1966 [4 March, 1966], No. 19028/66. Heading F4S. [Also in Division B2] In a refuse-burning installation, e.g. for the disposal of waste paper, the smoke produced is passed via a conduit 18 and a chamber 17 through cyclone separators 11 mounted in a housing 10 and having vortex-producing vanes 14 at their inlet ends, separated dust being collected in a lower chamber in the housing and the cleaned smoke being discharged via vortex finders 15 into an upper chamber 30. The smoke may be blown through the conduit 18 or it may be drawn therethrough by means of a blower 31 which discharges the cleaned smoke into a chimney via a passage 33. Air to be heated, for use in a warm air heating installation, is drawn by a blower 22 via a filter 19 into a passage 20 through which extend the separators 11 which at this region are provided with fins 16 to improve the heat transfer between the smoke and the air. The blower delivers the heated air through tubes 23 extending through the chamber 30 in which it is further heated by the cleaned smoke. The warm air is discharged into a chamber 24 which communicates with the space to be heated through adjustable louvres 25. Control of the air temperature may be effected by means of fresh air admitted to the passage 20 via a valve 26. Alternatively, the direction of flow of the air to be heated may be reversed, the preheating taking place first through the tubes 23 and final heating in the vicinity of the heat-exchange surfaces of the vortex separators 11.

Filed: 1946-06-26
Abstract: 639,394. Sparking preventing in switches. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 26, 1946, No. 19069. Convention date, April 25, 1942. [Class 38 (v)] A high-power D.C. switch 9, 10, controlling a load 3 is shunted by a mercury-cathode discharge tube 4 which strikes when the switch opens, thereby absorbing the arc. An auxiliary switch 11 operated as the switch 9, 10, opens, controls a relay 13 which after a short interval insufficient to damage the switch 9, 10, closes contacts 14, enabling a condenser 15 to discharge through an ignition electrode 6, thereby initiating discharge of the tube 4. After a further short interval when the gap of the switch 9, 10, is sufficiently long and deionized, by known means, to prevent restriking of the arc, contacts 16 close, enabling a condenser 18 to ignite a tube 17 through which a condenser 8, charged by a device 19, discharges, thereby extinguishing the tube 4. The tube 17 is extinguished when the condenser 8 and an auxiliary condenser 20 become charged, the capacity of the latter being such that the greater proportion of the circuit voltage 1 appears across its terminals. For periodic operation of the switch a leakage resistance 21 is provided to enable the condenser 20 to discharge in the interval. The dimensions of the tube 4 and its time of operation must be such that after it has operated, the voltage required to restrike it is greater than the circuit voltage; a small tube of about 100 c.c. capacity is used, the theory being explained in the Specification with the aid of a graph, Fig. 3 (not shown). A switch may replace the tube 17, Fig. 1 (not shown), and the arrangement is also suitable for A.C. interruption during the half-cycle which is conducted by the tube.

Patent GB-376007-A (GB)
Title: Improvements in and relating to hydraulic shock absorbers
IPC: F16F9/14
Filed: 1931-07-02
Abstract: 376,007. Hydraulic shock-absorbers. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(American Chain Co., Inc.; 929, Connecticut Avenue, Bridgeport, Connecticut, U.S.A.) July 2, 1931, No. 19157. [Class 108 (iii).] In an hydraulic shock-absorber of the type in which vanes oscillate within a cylindrical casing, liquid flows through a passage of variable cross-sectional area in series with a second passage provided with a spring-controlled valve. In the constructions shown in Figs. 1 and 5, the operating shaft 6 carries a vane 33 which is pressed outwards by a spring 34 into engagement with a cylindrical sleeve 3 secured against rotation in the outer casing 1 by a projection 36 which also secures the abutment 35 against movement. When the vane 33 moves in an anticlockwise direction, liquid flows through a slot 37 in the abutment 35, a groove 38 in the operating shaft 6, a port 39 and a one-way valve 40 controlled by a spring 41, the rate of flow being dependent upon the overlap of the slot 37 and the groove 38 and also upon the resistance of the valve 40. When the vane moves in a clockwise direction, liquid flows similarly through the slot 44, the groove 38a, the port 45 and the valve 46 to the other side of the vane. With movement of greater amplitude, the grooves 38, 38a are covered and the liquid pressures rise abruptly. Liquid leaking from the working compartments passes through a slot 21 in the endplate 20 into the reservoir 26 from which it may be supplied through one-way valves 50, 52 to the working chambers. In a modification shown in Figs. 9 and 10, liquid flows through tapering grooves 61, 62 in the endplate 60 and thence through spring-controlled valves 63 to the other side of the vane, the effective area of flow through the groove 61 being thus dependent uponthe position of the vanes. Liquid may also flow through passages in the abutment, the flow being regulated by spring-controlled valves 67, 69 and by grooves 73, 74 in a screwed pin 72 adjustable externally of the apparatus. The cylindrical shell 78 is loose in the casing 57 and is free to yield slightly when the internal pressures are excessive thus acting as a safety valve. In the modification shown in Fig. 14 liquid flows, when the vane moves in the clockwise direction, through a port 96, a duct 93 and past the spring-controlled valve 95, the opening of the port 96 into the duct 93 being varied, according to the position of the operating shaft, by a ball 97 engaging a slot 91 in the shaft. A spring forces the ball on to the shaft. Movement of the vane in the opposite direction is controlled by a similar but independent series of valves and passages. A spring-controlled safety valve 98 is arranged axially in the operating shaft.

Filed: 1972-04-25
Abstract: 1382110 Irrigation of soil and feeding of plants SEALFIRE 25 April 1972 [26 April 1971] 19201/72 Heading A1B [Also in Division F2] Liquid, or a mixture of gas and liquid, flows through pipe 101 and control valve 102 into an underground pipe system 103 provided with diffusion points each comprising delivery means 104, 105 connected by a pipe to porous diffusers 106, 108. The flow rate at each diffusion point is controlled by a calibrated orifice in the delivery means, by the length and diameter of the connecting pipe, or by the porosity of the porous diffuser. In Fig. 2a, the delivery means is in the form of a coupling nipple 205 which has a calibrated orifice 239 and a nose 238 fitting into a hole in the supply tube 210, the nipple being held in position by a steel clip 241 and connected by a -flexible pipe 207 to the porous diffuser which is in the form of a porous tube closed at its free end by a plug. In another embodiment, Figs. 4a and 4b (not shown), the delivery means, connecting pipe and porous diffuser are combined into a single unit including a flat porous plate. An automatic valve 119 Fig. 1 or (619) Fig. 6 (not shown) may be positioned above ground level so as to ensure that when the system empties, air can enter and thus stop any suction effect through the diffusers. Syphon effects may also be stopped by injecting gas through cock 173 and pipe 172 into the system when cock 102 is closed. A programming device 118 may be used for the automatic control of the system. An automatic diffuser coupling has a needle 775, Fig. 7, which is fixedly attached to a porous wall 758 and fits into orifice 774 in elastic diaphragm 776 so that as the pressure in the system changes then the diaphragm moves and size of the orifice varies so as to alter the rate of flow of fluid. This device therefore automatically regulates the flow rate of the fluid.

Abstract: 764,588. Programming for machine-tools; jigs. BRITISH THOMSON-HOUSTON CO., Ltd. July 7, 1954 [July 13, 1953], No. 19360/53. Class 83 (3). [Also in Group XXXVIII] An automatically-operable positioning-apparatus for a machine-tool comprises a reference member 3 in the form of a bar of magnetic material having accurately spaced teeth or non- magnetic inserts to form reference-positions whose spacing is, for example, one inch, which is fixed to the tool-slide 1 which is adjustable by a lead screw 2 driven through a gear-box 11 by a motor M2. A sensing-head 4, containing coils, co-operates with the member 3 to produce an error-signal whenever the sensing-head is in misalignment with an adjacent referenceposition. The sensing-head is movably mounted on the bed of the machine, to which the work is fixed, and is adjustable by a micrometer screw 5 driven through a gear-box 16 by a motor M1. Control handles 10a, 10b set the integral part of the dimension, and handles 6d, 7d, 9d, 10d set the fractional part. Handles 6d &c. control the rotation of synchros 6, 7, 9, respectively, the rotations being added together by differential mechanisms 6b, 7b, 9b and gearing, and controlling synchros S6, S7, S9. The synchros S6, S7, S9 are electrically coupled to synchros S6A, S7A, S9A to produce misalignment signals which are fed to an amplifier A1 to control the motor M1 and displace the sensing head until the misalignment is reduced to zero. Similarly, handles 10a, 10b control the rotation of shaft 8 to control the synchro S8 to produce, through its electrical link with synchro S8A, misalignment signals which are fed through amplifiers A2, A4 to control the motor M2 and effect displacement of the tool slide 1. In order to adjust the tool slide and reference member 3 to a position approximating to the fractional dimension set in by the micrometer screw 5, the rotation of shaft 9 is added through gearing 9c and differential 10 to the movement of shaft 8, and when this position is reached the reduction of the error signal from synchro S8A causes a changeover switch P to operate, whereby the error signal from the sensing head 4 is fed via amplifier A3 and amplifier A4 to control the motor M2. Operation of switch P also effects an increase in the ratio of gearing 11 for the final adjustment, and when the desired position is reached the motor M2 may be disconnected and a mechanical clamping-device 12 operated. The handle 10c is used for setting in a datum dimension and is adjusted prior to the setting of the other handles. The information for positioning the tool-slide or table or controlling the depth of feed may be set in either by hand, punched card, or tape, the mechanism for reading the latter being of contact or photoelectric type.
