Abstract: A heat-hardenable phenol- or substituted phenol-formaldehyde reaction product having a minimum water-dilutability of 500% is mixed with 0,005%-1,0%, by weight based on the solids content of the phenol-formaldehyde reaction product, of (1) an acrylamide polymer wherein 0,5%-40% of the amide groups have been hydrolysed or otherwise replaced by carboxyl groups; (2) an N-alkyl-substituted acrylamide polymer; (3) an acrylamide copolymer containing at least 60% by weight of combined acrylamide; (4) a hydrolysed N-alkyl substituted acrylamide polymer containing at least 60% by weight of combined N-alkyl substituted acrylamide or (5) a hydrolysed acrylamide copolymer containing at least 60% by weight of combined acrylamide.  Several N-alkyl and N, N-dialkyl acrylamides are specified including N-allyl and N, N-diallyl acrylamide.  Many monomers are mentioned which can be copolymerized with the acrylamide and among these are vinyl esters, vinyl ethers, vinyl and vinylidene halides, allyl type alcohols, unsaturated monohydric alcohol esters of monobasic acids, acrylic acid and alkacrylic acids and their esters and amides including substituted amides, alkacrylonitriles, aromatic and aliphatic vinyl compounds, e.g. isobutylene, styrene, dichlorostyrene and vinyl naphthalene and a , b -unsaturated polycarboxylic acids and the alkyl esters thereof.  The phenolformaldehyde reaction product may be prepared by reacting phenol, cresol or xylenol with from 1-4 mols of formaldehyde in the form of formalin or paraformaldehyde, in the presence of an alkaline catalyst such as an alkaline metal hydroxide or carbonate, an alkaline earth metal oxide or hydroxide or quaternary ammonium hydroxides having ethyl, aryl, hydroxyaryl or tertiary amine substituents, followed by complete or part neutralization with mineral or organic acids or salts thereof; several preparations are described.  In Example 1, a 1% aqueous solution of a polyacrylamide hydrolyte having a maximum of 15% of the amide groups replaced by carboxyl groups was added to various phenol-formaldehyde reaction products and the mixture diluted to a 50% solids content.  Other acrylamide polymers used in the examples are a copolymer of acrylamide (69%) and N-(dimethylaminopropyl) acrylamide and a homopolymer of N, N-dimethylacrylamide.  In Example 4, the phenolformaldehyde reaction product is 2, 4, 6-tris (hydroxymethyl) phenol.  An acidic natural resin, e.g. rosin or a derivative thereof, is a useful extender.  The mixtures are used for bonding mineral fibres.

Title: Frequency deviation alarm circuit
IPC: H03F1/54
Filed: 1940-04-30
Abstract: 540,838. Frequency measurements. STANDARD TELEPHONES & CABLES, Ltd., and FRANKTON, W. J. April 30, 1940, No. 7799. [Class 37] In an arrangement for giving an indication or alarm when the frequency of an input current exceeds a predetermined amount, the input current actuates a relay which in one position closes a charging circuit for a condenser and in the other position discharges this condenser into a second condenser shunted by a dissipating resistance and an indicating device or alarm is actuated when the voltage across the second condenser exceeds a predetermined value, Two nominally identical frequencies, f, f+s, for example from the controlling and controlled master oscillator of a carrier wave signalling system, are fed to the primary windings of transformers T1, T2. The divided secondary windings of these are connected as shown to diagonal points of two rectifier bridges B1, B2, the loads of which are formed by the halves of the winding of a relay P. The effects of the difference frequency currents are additive in the relay winding and operate the relay. A condenser Cl is thereby charged once per cycle and partially discharged into a condenser C2. This is shunted by a resistance R2 and the auxiliary gap of a threeelectrode neon lamp N. At a certain frequency the peak voltage across the condenser C2 is sufficiently high to cause momentary ionisation of the neon lamp and set up a discharge in the neon gap of the tube, operating an alarm relay R. The voltage V of the battery is chosen to lie between the striking and maintaining voltages of the gap. As the alarm is self-locking a release key K is provided to stop the discharge in the main gap. The alarm may be made selfrestoring by supplying the main gap with power from an A.C. source or by interrupting the D.C. supply periodically, for example by means of a clock.

IPC: F16K21/18
Filed: 1962-02-28
Abstract: 968,294. Valves. AVERY-HARDOLL Ltd. Jan. 10, 1963 [Feb. 28, 1962], No. 7842/62. Heading F2V. A valve controlling the flow of liquid into a tank 10 comprises a valve closure member 16, connected to a piston 18 which divides a chamber 13 into two chambers 22, 23. The valve is opened to admit liquid to the tank by the liquid opening a valve 24 which moves a rod 58 to open a port 56 to allow flow to a conduit 47 and nozzle 35. The jet from nozzle 35 is directed to a pitot head 39 to provide a pressure in chamber 23 to open the valve 16. The jet from the nozzle 35 is cylindrical all the time air is drawn through a pipe 43 and passage 41. As the liquid level rises, liquid rises in an open tube 51 and covers the pitot head 39 and rises up the tube 34. The pressure from the jet 35 is thus gradually reduced and the valve 16 progressively closes until the level reaches the top of tube 43 and air is no longer drawn in. The jet then spreads and the valve 16 closes completely. The valve 16 can be opened manually by a lever 59 to allow flow from the tank.

Title: Fuel injection systems for internal combustion engines
IPC: F02M69/18
Filed: 1964-02-25
Abstract: 1, 098, 823. Spray carburetters; centrifugal flow pumps. PETROL INJECTION Ltd. and H.E. Jackson. Feb.4, 1965 [Feb. 25, 1964; June 24, 1964], Nos. 7895/64 and 26173/64. Headings F1B and F1C. In a fuel injector system wherein fuel injectors 9, Fig. 1, in the inlet manifold branches are branched off from a circuit 8, 47, through which fuel is continuously pumped from a tank 2 and returned thereto, the fuel is fed to the injectors at a pressure varying with engine speed by a centrifugal impeller 3, metered by a valve 13 in accordance with engine load as measured by throttle position or intake manifold pressure, and atomized in the nozzles 9 by compressed air fed thereto by a pump 14A. The fuel circuit comprises a supply pump 1, return pump 18, impeller 3, air separator 7, and balance valve 16 loaded by the compressed air pressure from pump 14A. A relief valve 15 admits atmospheric air to the compressed air system if suction develops therein at high intake manifold suction. The metering valve 13, shown in detail in Figs. 5-7 (not shown) comprises a rotary sleeve (42) controlled by a cam (48) actuated by an intake manifold suction responsive piston (58), the sleeve, having a metering slot (38). At idling a diaphragm (66) connected by pipe (70) to a suction port 26 adjacent the throttle valve moves a lever (65) to the right to over-ride cam (48) and set valve (42) to its idling position. The suction chamber (31), Fig. 5 (not shown) may also have incorporated therein an accelerating device which connects the chamber to atmosphere during acceleration to move piston (55) to the maximum fuel position. The injectors Fig. 8 (not shown) comprise a fuel chamber (72) and compressed air chamber (73), the atomized fuel being injected through nozzle (74); in a modification Fig. 13 (not shown) the fuel flows through a tube (335) and the compressed air through an annular space therearound. Flow equalizing restrictions 11 may be provided by stainless steel capillaries in the fuel supply pipes 10, Fig. 1, or in the injectors. A cut-off valve 5, Fig. 1, shown in detail in Fig. 9 (not shown) comprises a flat valve (95) which rests on a lower seat 93 when the engine is stopped to cut-off the fuel. Starting of the engine lifts the valve to an intermediate flow position in which it is held by a piston (111) raised by pump pressure to operate locking balls (115) preventing return of the valve to its lower seat. At over-running the high intake manifold suction acting on diaphragm (105) forces valve (95) against its upper seat 94 to interrupt the fuel supply. A by-pass valve 23, Fig. 1, adjusts the fuel supply in accordance with atmospheric pressure and temperature and in Fig. 11 (not shown) the by-pass valve (231) can be closed manually to increase the fuel supply for starting. The supply and return pumps 1, 18, form a combined unit with impellers (603), (604) Fig. 16 (not shown) separated by a stationary partition (615) and driven by an electric motor 601. Reference has been directed by the Comptroller to Specification 1, 045,150.

Abstract: 779,759. Photographic shutters. GAUTHIER GES., A. March 18, 1954 [March 18, 1953], No. 7938/54. Class 98(1) 'In a shutter having reciprocating pivoting blades controlled by an operating mechanism comprising a master member, a blade driving member, a speed setting member, and an element adapted to provide a driving connection between the master member and the blade driving member, the operating mechanism also includes a first additional member adapted to transmit the movement of the master member to the driving member and a second additional member movable at will into and out of a fixed operative position in which it renders the sail element inoperative during the opening of the shutter but allows it to become operative again to effect the closing of the shutter. As shown, in a shutter wherein the blade ring 3 is oscillated by means of a half-round pin 3<SP>11</SP> engaged by the crook 13<SP>1</SP> of a finger on a link 13 pivoted on a spring-driven rotatable master member 6, by adjusting the speed setting cam ring (Fig. 3, not shown) for fast exposures, for one or more of which additional driving springs may be used, the link 13 is disengaged by an arm 20<SP>11</SP> on a lever 20 which is moved inwardly and a lever 16 is moved inwardly to bring its edge 16<SP>1</SP> into the path of a half-round pin 17 on the master member. On tripping the master member latch 9, the master member then rotates freely with the link 13 idling until the pin 17 drives the lever 16 anticlockwise so that its edge 16<SP>11</SP> engages the pin 3<SP>11</SP> and drives the blade ring clockwise to open the shutter. When the pin 17 has passed the edge 16<SP>1</SP> so that the lever 16 is returned to the position shown. the master member and link have reached dead centre and the crooked finger of the link re-engages the pin 3<SP>11</SP> so that continued movement of the master member closes the shutter in the usual way while an assisting closing movement is effected by the pin 3<SP>11</SP> rebounding from the edge 20<SP>111</SP> of the lever 20. Slow exposures are produced under the control of the speed setting ring by engaging in the blade driving mechanism a retard train which operates during the normal "shutter open" period.

Title: Improved process for the production of cellulose xanthate solutions
IPC: D01F2/08
Filed: 1935-03-14
Abstract: Viscose is manufactured in a continuous series of operations all carried out at 12--18 DEG  C., wherein cellulose pulp is alkalized in a sodium hydroxide solution of sufficient concentration and quantity to effect complete conversion to alkali cellulose, this quantity being about 13 parts by weight per 4 parts of a -cellulose when the concentration of the solution is 19 per cent, and being varied proportionally for other concentrations, and wherein the alkali cellulose is xanthated, dissolved in dilute alkali, and filtered ready for immediate precipitation.  The process avoids the usual steps of ageing.  Preferably, a high p  grade a -cellulose material is used, but poorer quality material may be used if desired.  In an example, cellulose pulp is formed into crumbs and mixed in a closed container with the requisite quantity of caustic soda for 20--40 minutes, the time being less for high viscosity pulp than for pulp of low viscosity.  The alkali cellulose without being ripened is mixed with carbon disulphide which is sprayed into the container during the mixing. The cellulose xanthate is dissolved in dilute caustic soda preferably containing a small amount of sodium sulphite.  If desired, the xanthating and dissolving processes may be combined to one operation.  The temperature may be kept below 18 DEG  C. by circulation of water, brine, or ammonia through the jacket of the mixing tank.  Sodium oleate or stearate may be added to the viscose to reduce surface tension.  The viscose is filtered through one or more presses and pumped to containers.  It is then ready to be cast or extruded to form artificial filaments, sheets, or foils.

[Also in Division F2] In a braking arrangement in a rail vehicle comprising two symmetrically arranged brake block suspensions 3, 3a which are positioned opposite to each other at the same side of a wheel set 18 and which are rotatably suported on trunnion shaped ends 9, 9a of a tie rod 16 which is adjusted to correspond with the wheel gauge in use, the tie rod 16 is suported in an axially and rotary movable manner in bearings 11, 11a which are attached to the vehicle frame. The brake block suspension may be used with laterally movable wheel sets for railway slewing crane. The trunnions 9, 9a on which the brake block suspensions 3, 3a pivot may form as separate parts of the tie rod 16 as shown or may be formed by the ends of the tie rod 16. The trunnions 9, 9a are rotatable and axially movable in bearings 11, 11a which have bushes (13, Fig. 3, not shown), in which the trunnions run. The bearing 11, 11a may be lubricated from a device 15 or the bushes (13) may be of a self lubricating material. Adjustment of the brake block suspension to suit the variable gauge of the wheels is obtained by selecting the required connection between tie rod 16 and the trunnions 9, 9a. The tie rod 16 has a hole which cooperates by means of bolt 20 with one of a number of holes 19 in the trunnion 9, 9a to enable this adjustment. The brakes are operated from a rod 1 and brake block clearance is adjustable by stop 8. The angular position of the brake block 4 on the brake block suspension 3, 3a may be adjusted by device 6. The axial movement of the tie rod 16 within the bearings 11, 11a due to lateral movement of the wheels such as by frictional forces or the force at the wheel flange ensures that with any gauge size the brake blocks 4 are correspondingly lined up with the wheels 7.
