Patent GB-822262-A (GB)
Title: Improvements in and relating to thermally stable bonded siliceous strictures
IPC: C03C25/26
Filed: 1955-11-30
Abstract: 822,262. Bonded fibrous materials. OWENSCORNING FIBERGLAS CORPORATION. Nov. 30, 1955 [Dec. 10, 1954; Dec. 27, 1954], No. 16308/59. Divided out of 822,261. Class 140. A method of producing a bonded fibrous material comprises arranging inorganic siliceous fibres into an interfelted or porous mass, applying to the fibre mass a binder comprising 10-90 parts by weight of an alkyd resin and 90-10 parts by weight of a urea borate condensation reaction product and then baking the bindercontaining fibre mass to set the binder. Specified siliceous fibres are glass, mineral wool and asbestos fibres. A suitable alkyl resin is the product of a condensation reaction of a polyhydric alcohol, such as pentaerythritol and an unsaturated dicarboxylic acid such as maleic anhydride or maleic or fumaric acid and a polyglycol such as ethylene glycol. A suitable ureaborate condensation reaction product is the condensation reaction product of urea, boric acid, formaldehyde and ethylene glycol; for the ethylene glycol there may be substituted other polyhydric alcohols such as diethylene glycol, propylene glycol or glycerol; and in place of all or part of the urea and the formaldehyde present in the urea borate condensation reaction product there may be substituted other nitrogenbased aldehyde resins such as dicyandiamide formaldehyde, melamine formaldehyde or guanidine formaldehyde. The heat-resistant quality of siliceous fibrous material bonded with a urea borate condensation reaction product in accordance with the present invention may be improved by impregnation with a solution or suspension of silicic acid. The latter impregnating solution may also comprise a urea borate condensation reaction product and a siliceous filler. Specified siliceous fillers are aluminium silicate, silica, clay and bentonite.

Title: An instrument for graphically recording series of observations involving two factors
Filed: 1922-06-13
Abstract: 205,145. Holland, E., and Collingwood, R. G. June, 13, 1922. Mothematical drawing- appliances.-An instrument for mechanically plotting the results of a series of observations involving two factors comprises a rotatable drum 1 formed with a graduated helical groove on its surface and mounted on a hollow spindle 2 which is supported in brackets 3, 4. These brackets are formed with drilled bosses 5, 7 through which pass rods 9, 10. At one end the spindle 2 carries a collar 15 provided with a handle 14 for rotating the drum, while the other end of the spindle is enlarged and a collar 16 having an internally threaded extension 16<1> is screwed into the enfarged part. A screw 18 engages in the extension 16<1> and extends into the spindle. Clamped to the screw is a bar 19 carrying a rod 22 which is screwed into a lug on an indicator 25 sliding on the rods 9, 10 carrying a pointer which can be set to any graduation on the drum. The indicator also carries a marker 44. A counting device 32 is operated by gearing 34, 33 from the drum and a carbon ribbon 70 wound on bobbins 36, 37 passes in proximity to the lower surface of the counting wheels. The drum with associated devices is pivoted to the table at 41 and can be depressed by an extension 43 of the bracket 3 after the indicator has been set, so that the marker is brought into contact with the paper. At the same time the ribbon 70 is pressed on the paper to mark the numerical value of the observation. The paper sheet 55 is mounted on parallel rollers 56, 57 so as to be traversed in a direction at right angles to the axis of the drum. To enable observations from a datum other than zero to be recorded, the drum is provided with an axially adjustable sleeve 26 graduated to the same scale as the drum but in the reverse direction, this sleeve being set to the given datum on the drum and the pointer being set to the required graduation on the sleeve.

COURTAULDS Ltd. 24 May, 1966 [25 May, 1965], No. 22151/65. Heading F4S. [Also in Divisions B1 and F2] In a heat exchanger in which tubes 3 of thin thermoplastic film extend vertically between upper and lower tube plates (only the lower plate 1 being shown), the tubes are suspended from the top plate which is rigidly mounted, and at least partially support the weight of the bottom plate whereby the tubes are tensioned. The tension may be supplemented by the addition of weights to the bottom plate or by a downwardly-urging spring; or if necessary, the tension may be reduced by an upwardly-urging spring. The tube assembly shown is disposed in a tower 2 and is intended for use in a desalination process. As shown, the plate 1 has an upstanding flange 7 providing a well in which brine flowing down the tubes collects and is drawn off. Stand pipes 4 extend upwardly from the tube plate and prevent leakage of brine into the tubes should one or other of these become holed below the brine level. The tube ends are clamped by tubular wedges 5 to the stand pipes 4. A seal between the tower wall and the tube plate may be provided by a flexible membrane 11. Alternatively a liquid seal may be provided (Fig. 2).

[Class 56] Apparatus for bending glass tubing comprises means for heating the tubing to a pliable state and an associated, re-shaping mould comprising a concave trough-shaped surface formed with a tube - receiving groove and means for pushing the pliable tubing against and through the groove. As shown, glass tubing 1 supported by grooved rollers 2 is guided towards the double set of grooved feed rollers 3, 3<1> and 4, 4<1> which are rotated by an electric motor 8. The tubing 1 is fed through an electric oven 19 where it is heated to a temperature 100‹ C. or so below its softening point. It then passes beneath an electrically heated shoe 21 mounted on the end of the oven, to a pair of power-driven grooved rollers 22, 23 which guide the tube to the mould 24, which is hollowed out on the side facing the tubing to form a concave semicircular cavity 36 with a tube receiving groove 37 of arcuate form. The upper end of the groove 37 is aligned tangentially with the tubing 1 as it emerges from between the rollers 22, 23. Where the groove 37 is of helical form, the mould is disposed at an angle, relative to the straight tubing 1 corresponding to the pitch of the groove. Before entering the groove, the tubing is subjected to supplementary heating by gas burners 32, 33 and is guided and supported in entering the groove by a roller 38, located immediately inward of the groove 37. A revolving cylinder mounted adjacent to one side of the mould may be provided to pick up the helically coiled tubing.

Title: Improved timing apparatus particularly for electric welding machines
IPC: B23K11/26
Filed: 1955-06-14
Abstract: 771,263. Control systems for resistance welders. GENERAL ELECTRIC CO. June 14, 1955 [June 14, 1954], No. 17134/55. Class 38 (4). Timing apparatus for controlling the " weld " and " cool " periods in resistance welding comprises a valve 40 having connected to its grid a " weld" " timing circuit 52, 53, 56 which is charged up over rectifiers 84-86 when a valve 60 is rendered conducting by operation of an initiating switch 67. The voltage of condenser 53 now allows valve 40 to conduct, thereby energizing firing transformer 18 for ignitron 9, which conducts to initiate flow of welding current. Valve 41 is arranged to trail 40 and, through firing transformer 28, causes the other welding ignitron 10 to conduct. Conduction of valve 40 also energizes a transformer 73 which, in association with rectifiers 72, 82, 83 charges condensers 68, 69 of a " cool time circuit 68-70, the voltage on condenser 68 being then applied as negative bias to valve 60 which, consequently, becomes non-conducting and terminates charging of the " weld " time circuit. The condensers 52, 53 then discharge into one other at a rate determined by resistor 56 and eventually the voltage across 53 falls to the cut-off value of valve 40, which extinguishes and terminates flow of welding current. Timing circuit 68-70 now commences to time out, progressively reducing the bias on valve 60, which (provided switch 67 is maintained closed) eventually conducts to initiate another welding cycle. During the " weld " period the condensers 68, 69 of the " cool timing circuit receive charge at about only half full voltage due to the inclusion of a resistor 78 in the supply circuit to the charging transformer 73. The condensers are, however, changed to full voltage when valve 40 times out by a previously non-conducting valve 74 then becoming conducting and providing an alternative energization circuit for transformer 73. By this means the instant of initiation of the " cool " period is rendered independent of supply circuit voltage fluctuations. Specification 659,996 is referred to.
