Abstract: 838,471. Pipe couplings. MARKHAM & CO. Ltd., BOWYER, G. A., LONGMATE, C. D., and SPRAGG, H. Jan. 30, 1959 [Jan. 31, 1958], No. 3356/58. Class 99(1). A coupling for securing together the ends of pipes 10, 11 having outwardly-extending flanges 12, 13 comprises two collars 14, 15 encircling and relatively rotatable on the pipe 10 which collars are provided with engaging faces 23, 25 so shaped and arranged that relative rotation between the collars varies the effective combined length thereof, the collar 15 being arranged to abut the face 16 of the flange 12 and the collar 14 having fixed or adjustably secured thereto a number of arms 26 which extend across the two flanges and are provided with inwardly-directed fingers 27 which overlie the flange 13. Relative rotation between the collars in one sense increases the axial length thereof resulting in the pipes being clamped together whilst relative rotation in the opposite sense reduces the effective axial length of the collars enabling the arms and fingers to be moved clear of the flange 13 and the pipes to be separated. As shown in Figs. 1 and 3, the flange 12 has a circumferential recess 20 for a packing ring 21, and the collar 15 is formed with a rim 18 which overlies and aligns the flanges 12, 13. Axial projections 22 on the collar 15 have cam faces 23 of helical form, and the collar carries an outwardly extending lever arm 24 provided a recess 24a ; the collar 14 also has axial projections the end faces 25 are cam-shaped and engage the projections 22. To facilitate manipulation of the pipe 10, the collar 14 is provided with a lifting handle 28 having trunnion pins 30, received in lugs 29 on the collar, and a projection 31, which when the handle lies close to the pipes, is disposed in the path of movement of the arm 24 and within the recess 24a thereof when the arm has been moved into a position to clamp the flanges together. A loose key and keyway may be provided between the collar 14 and the pipe 10 to permit only relative axial movement between the collars 14, 15 ; alternatively, the face of the flange 13 is provided with abutment surfaces to engage the sides of the fingers 27. The peripheral surfaces of the flanges may be cylindrical or conical. In a modification, the collar 14, Fig. 4, has an outwardly extending lug 32 formed with a socket 33, rectangular in cross-section, through which extends a T-shaped member 35 the shank of the member having pivoted thereon a handle 28 swingable towards and away from the pipes to allow the projection 31 to be disposed in the path of the arm 24. In a further modification, the arms 26, Fig. 6, which are pivotally mounted on the collar 14 and swing inwards and outwards relative to the flange 13 have end faces shaped to provide the cam surfaces 25, the collar 15 being formed with projections 47, which, when the collar is rotated to release the coupling, force the arms outwardly. A member 50 pivotally carrying a looped handle 53 slides into a socket 49 in a lug 48 on the collar 14.

Patent GB-399820-A (GB)
Title: Manufacture of alkali cyanates
IPC: C01C3/14
Filed: 1932-02-08
Abstract: Alkali cyanates are obtained by causing carbon dioxide, carbon oxysulphide or a mixture thereof and ammonia to react on an alkali salt or a mixture of alkali salts in the presence of a gas capable of decomposing water, such as carbon monoxide but excluding hydrocarbons, at elevated temperatures below 800 DEG  C.  Inert gases may be added to the gas mixture.  The alkali salts which may be employed include sodium carbonate, sulphide and cyanide and alkali sulphites, thiosulphates and the like.  Sodium chloride is unsuitable.  The alkali salts may be used in the form of briquettes, mixed with inert substances, activating substances such as carbon, alkaline earth oxides, e.g. those of calcium or magnesium, or catalysts such as metals or metal compounds.  The alkali salts may be used in a molten condition with or without the addition of substances such as cyanates which lower the melting point.  The reaction may take place under reduced or elevated pressure.  In the latter case the alkali salt may be dissolved or suspended in a solvent such as alcohol or ammonia.  The gases may be passed over the salts at such a speed that there remains a substantial excess of reacting gases with respect to volatile reaction products.  One or more of the reacting gases may be present in excess of the quantity required for the reaction. According to one example a gas mixture containing carbon dioxide, carbon monoxide and ammonia is passed through a melt of sodium cyanate and sodium sulphide at 650 DEG  C.  A further example describes the same treatment of a melt of sodium cyanate and sodium carbonate.  Specification 358,745 is referred to.  The Specification as open to inspection under Sect. 91 is not restricted to carrying out the reaction in the presence of gases such as carbon monoxide, states that nitrogen, hydrogen, and hydrocarbons may be present in the gas mixtures, and refers to alkali nitrite as a starting material.  This subject-matter does not appear in the Specification as accepted.

Patent GB-548112-A (GB)
Title: Improvements in or relating to the production of artificial filaments
IPC: D01D5/04
Filed: 1941-03-20
Abstract: 548,112. Artificial filaments &c. BRITISH CELANESE, Ltd. March 20, 1941, No. 3811. Convention date, March 20, 1940. [Class 2 (ii)] Artificial filaments are obtained by extruding a spinning solution downwards into an evaporative setting medium, permitting the extruded bundle of filaments to fall by its own weight through the evaporative medium, and removing the bundle continuously with its extrusion and without tension from beneath the point at which it is extruded. The filaments may be converted into staple fibres either continuously with the production of the filaments or as a separate operation. The filaments are of high extensibility, resiliency, and thermal insulating properties. The apparatus employed may comprise one or more spinning cells, each provided with one or more nozzles for the extrusion of a bundle of filaments. A conveyer band may be provided to receive the filaments which may be collected together in the form of a sliver. The process is applicable to the production of filaments or fibres of cellulose acetate or other cellulose ester or ether. As shown in Fig. 1, filaments 7 from nozzles 4 fall by their own weight down the length of cells 5, and are received on a belt 8 which runs along the bottom of the cells. The belt travels at a speed equal to or slightly less than the speed at which the filaments fall upon it. The filaments emerge from between idler roller 12 and belt 8 as a sliver and pass through rollers 13, 14 which have a slightly greater peripheral speed than that of belt 8 so that the filaments in the sliver are straightened. The sliver is fed into coiling can 16. As shown in Fig. 2, the sliver is passed directly to a cutter for converting the filaments into staple fibres. A blast of compressed air passing through the annular space 21 draws the sliver 15 through cone 19 and conveys the straightened filaments to the cutter 22, the blades 24 of which co-operate with a stationary blade 25.

Title: Improvements in sensitive photographic materials
IPC: G03C1/76
Filed: 1941-03-21
Abstract: 550,775. Photographic printing paper and developing solutions. KODAK, Ltd., and BATLEY, A. March 21, 1941, No. 3841. [Class 98 (ii)] Photographic printing paper for printing from wet negatives comprises a paper support carrying a lieht sensitive silver salt emulsion laver having a layer of a binder which is insoluble in plain water but soluble in alkali solutions, such as a colourless overcoating of less than 25 thickness of a polyvinyl acid ester resin or a resin ester of a polybasic acid. Preferably the dried coating should not be more than 10 Á or even more than 5Á thick, and coatings as thin as 2 Á or lower can be used in some cases, a resin or low acid value being applied more thinly than one of high acid value. Thicker coatings can be used if longer development times are permissible. The coatings may be formed from a solution of polyvinyl phthalate in a mixture of ethylene glycol monomethylether, acetone, and methol alcohol, or from a resin formed by condensing a terpene, e.g. rosin, with an x: #-unsaturated poly-carboxylic acid or acid anhydride, e.g. maleic acid anhydride, or from an alkyd resin formed by condensing a polyhydric alcohol, e.g. glycols, glycerol, sugars, and simple derivatives thereof, with polycarboxylic acids, e.g. citric, maleic, phthalic, succinic, or tartaric acid, or from a hydrolysed natural resin of the kind described in Specification 511,180. In example 1, a solution of polyvinyl acetate phthalate of acid value 270 in acetone and ethylene glycol monomethyl ether is coated on the silver bromide emulsion layer of photographic paper and dried to give a layer 7Á thick. In example 2, a dried layer 15 # thick is formed from a solution of a rosin maleic anhydride adduct of acid value 250-275 in acetone and ethylene glycol monomethyl ether. In example 3, a dried layer 7 Á thick is formed from a solution of Abralac PK (Registered Trade Mark) in acetone and ethylene glycol monomethyl ether. In example 4, a dried layer 2-3 Á thick is formed from a solution of hydrolysed soft lac in industrial spirits. In example 5, a layer 15 Á thick is formed from a solution of rosin maleic anhydride adduct of acid value 250- 275 and Abralac BG in acetone. The wet negative may contain sodium thiosulphate, but not free alkali. Specifications 355,281, [Group IV], 450,220, 524,378 and 529,035 also are referred to. The Provisional Specification describes also a developer containing catechol, sodium sulphite, sodium hydroxide, and potassium bromide, and refers also to an acid value of at least 100 to 150.

Title: Improvements in or relating to letter spacing mechanism for typewriters
IPC: B41J19/42
Filed: 1924-02-14
Abstract: 233,073. Peeters, H. Feb. 14, 1924. Letter-spacing mechanism. - The escapement wheel 151 is engaged alternately by stop fingers 152, 153 mounted upon an oscillating frame consisting of two stop-supports 156 each mounted on two parallel arms 157, 158, the arms 158 being connected together by a transverse rod 159 provided near its centre, with a finger or stop 160. The escapement wheel is mounted on a shaft 150 which also carries a pinion 133 meshing with the carriage rack 134, and the teeth of the escapement wheel are so shaped that the rotation of the wheel under the tension of the driving spring produces oscillation of the pivoted frame. The oscillation of the frame is controlled by the finger 160 engaging the upturned end of a pivoted stop 161. the other end 165 of which is engaged by one of the teeth of a cam wheel 166. A compression spring 164 ncrmally holds the stop 161 against the finger 160, The stop 161 is rocked by the rotation of the cam wheel 166 and the finger 160 is thereby released, enabling the carriage to be moved. The rotation of the cam wheel is produced by the longitudinal movement of a. rod 168, which is pivoted at 171 to a parallel bar 170 and is provided at one end with a finger 167 engaging the teeth of the cam wheel. The other end of the rod 168 terminates in an inclined plane 169. The bar 170 is pivoted at its ends to arms 172 keyed upon shafts 173 and adapted to be rocked by pawls 174, either when the lever arms 110, 111 are automatically rocked after each printing operation, or when the space lever 108 is operated. During the longitudinal movement of the bar 170 and the rod 168 pivoted thereto, an inclined plane 169 comes into contact with an eccentric cam 175 mounted on a spindle 176, which can be adjusted by means of a handle, and the rod 168 is turned to disengage the finger 167 from the cam wheel 166 after the latter has rotated through an angle corresponding to one or more teeth, according to the position of the eccentric cam 175, and consequently the frame makes the same number of oscillations before being locked. Each oscillation of the frame produces an advance of the carriage through a distance corresponding to one character. Specifications 233,071, 233,072, and 233,074 are referred to. Carriage-releasing arrangements.-The detents 152, 153 can be withdrawn simultaneously from the escapement wheel 151 by depressing a lever 129 bearing upon a lever 131, which is pivoted at one end 132, and is provided at the other end with a cross-bar 190 having bent ends 181 adapted to bear upon the outwardly bent lower ends 185 of rods 188, which are pivoted at 183 to the frame bars 157 and are connected to the outer ends of the detents. Springs 186, 187 restore the parts to their original positions.

Title: Automatic gain control systems
Inventor: JACOBSON ROBERT I
IPC: G01S13/44
Filed: 1955-02-09
Abstract: 802,900. Radar. SPERRY CORPORATION. Feb. 9, 1955, No. 3933/55. Drawings to Specification. Class 40 (7). In a radar system, directional information is obtained from the comparison of the outputs of two antennµ. The sum and difference of the outputs are derived; the difference signal amplitude corresponds to the target angular deviation and the relative phase-sense of the sum and difference signals indicates the sense of the deviation. The sum signal amplitude is a function of the echo signal strength and not the target azimuth position. As the difference signal amplitude will vary also with changes in the strength of the echo signal the gain of the difference signal amplifier is automatically adjusted to neutralize the effect of this on the amplifier output. The gain of the difference amplifier is controlled by a pilot pulse generator, the signals from which are introduced into the receiver during the interval between the transmitted pulses and which have an amplitude automatically adjusted to vary in proportion to the echo pulse amplitude. The gain of the difference amplifier is controlled only by the pilot pulse and not by the echo difference signal itself. The sum amplifier gain is controlled only by the echo sum signal so that the pilot pulse amplitude control, supplied from the output of this amplifier adjusts the pilot pulse amplitude to correspond with the echo amplitude charges.
