Abstract: 898,812. Measuring fluid flow. FOXBORO CO. April 4, 1961 [April 25, 1960], No. 12071/61. Class 69 (1).  Apparatus for the conversion of a non-linear flow-signal to a continuous measurement linearly corresponding to the flow-rate includes a balanceable member 76 with means 94 for applying to it a first force proportional to the rate of flow, power rotated means 10 producing, at 34, a centrifugal force which is transferred at 72 to the balanceable member 76 to oppose the first force on it and thereby to operate by changes of balance a power control 106 which alters the power applied to the rotated means 10, whereby its speed corresponds to the flow rate of the fluid ; also a brake 206, operated by the power-means to restrain the rotated means 10 when the power is varied to decelerate it. The apparatus, other than the brake assembly, is that described in Specification 815,115 in this Group in which the control 106 modifies air pressure supplied from an internal source through conduits 114 and 112 and feeds it through conduit 108 to drive a turbine disc 14 on the means 10. The pressure, thus modified, is fed off through a pipe 200 to bellows 202 controlled by a spring 214 and, which, when collapsed, moves an arm 204 to press the nylon tipped brake-plunger 206 against the disc 14. Whilst the forces on the member 76 are in balance the brake is not actuated, but a fall in pressure from the balanced position causes it to be applied.

Abstract: 457,730. Shock - absorbers. HENSS, P., Salzderhelden, Germany. May 4, 1936, No. 12562. Convention date, Dec. 12, 1935. [Class 108 (iii)] A shock - absorbing or pneumatic suspension device for vehicles comprises a bowlshaped rubber body b the rim b<1> of which abuts and, when compressed, expands against a plate d secured for example to the vehicle frame, and the interior of which is in communication with the atmosphere. The rubber body is enclosed in a casing c the lower end c<1> of which acts as a guide for a rod a which is connected to one of the vehicle road-wheels and supports the body b at its upper end. As shown, free exit of fluid from the bowl on compression of the device is permitted by a non-return valve f but the return flow is restricted by a port g in the valve. When the device is used as a vehicle suspension the valve may act in the opposite way so that the fluid-pressure in the bowl increases on compression. Shock is also partly absorbed by the expansion of the rubber body and by the friction between the rim of the body and the plate d, which may be reduced by coating the plate d with glycerine &c. In order to increase the stroke of the rod a, the plate d may be made conical. The valve f f may be replaced by a small hole in the plate d.

Filed: 1953-05-08
Abstract: Acidified aqueous solutions of urea-hexamethylenediamine - formaldehyde condensates (see Group IV (a)) are used for impregnating cloth, e.g. grey rayon gaberdine for crease-resisting purposes. Impregnation is followed by heating to set the resin. Specifications 641,703, 688,794, [both in Group IV (a)], and 695,148, [Group VIII], are referred to.ALSO:Thermosetting condensation products suitable for impregnation of cellulose are prepared by adding 0.005-0.1 mols. of hexamethylenediamine to 1-2.2 mols. of aqueous formaldehyde at a pH of 7.5-9 and a temperature below 20 DEG  C., the addition being sufficiently slow and the agitation of the mixture rapid enough to prevent precipitation, thereupon adding 1 mol. of urea and, if desired, heating to produce a clear solution with a pH of 7-8.6 which is then acidified with strong acid, e.g. sulphuric acid. The acid added is sufficient to neutralize part of the hexamethylenediamine forming a salt which acts as a latent curing catalyst.  The final solutions have a working life of 100 hours or more.  Examples are given of the preparation of condensation products and of their use for impregnating powdered cellulose to produce products which dry quickly to a state in which they may be ball-milled to produce moulding powders which gave moulded articles with high resistance to boiling water.  Tri-methyl phosphate may be added as a curing catalyst.  Other examples describe the production of various condensation products according to the invention and their use for the crease-proofing of rayon gabardine.  The products may also be used for adhesives, paper or cloth laminates, or baking enamels. Specifications 641,703, 688,794 and 695,148, [Group VIII], are referred to.
