Title: Improvements in or relating to control devices for the guiding of webs of material or the like
IPC: D06C3/00
Filed: 1938-09-22
Abstract: 521,742. Tentering-machines; fluid-pressure servomotor-control systems. TOOTAL BROADHURST LEE CO., Ltd., LAURIE, K. S., BROWN, A. S., and DALGLISH, J. Sept. 22, 1938, Nos. 27593/38 and 13180/39. [Class 42 (i)] [Also in Group XXIX] In a fabric tentering machine, the chain guides are adjusted by hydraulic means which is controlled electrically, pneumatically or hydraulically by feelers 51 in contact with the edges of the fabric &c. 1a. The leading ends 2 of the chain guides are adjusted by separate hydraulic rams 13 the ends of each of which are connected to the chambers 29, 31 of a valve 21. One of these chambers is connected to the pressure inlet 26 and the other to the outlet 27 when the spring loaded piston valve 23 moves from its central position owing to the air pressure in the bellows 34 being reduced or increased by the movement' of the feeler 51. The feeler valve is connected with a valve 44a in front of an air nozzle 44 carried by a bellows 48. The nozzle 44 is connected to the air supply 36 by pipes 43, 40 which are also connected to a bellows 45 controlling an air leak 45a in the air duct 37a which is connected directly to the bellows 34 and through a throttle valve 39 with the air supply 36. The bellows 48 is connected by a pipe 47 with the air duct 37a. If the fabric 1a moves the feeler 51 to close the nozzle 44, 'the pressure in the bellows 45 rises, the leak 45a is closed and the pressure in the duct 37a and the bellows 34 rises, thus effecting adjustment of the chain guides 2. The rise in pressure in the duct 37a and also in the bellows 48 moves the nozzle 44 away from the valve 44a and prevents hunting. Movement of the feeler 51 in the other direction causes a reduction of air pressure in the bellows 34 with corresponding adjustment of the chain guides 2. If the change of pressure due to the valve 44a and nozzle 44 is sufficient, the bellows 45 and leak 45a may be dispensed with. The whole feeler mechanism can be adjusted by means of a hand screw 57. Oil may be used instead of air, or the. feelers 51 may act through solenoids &c.

Abstract: 754,993. Supply systems for space discharge tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 24, 1954 [Sept. 28, 1953], No. 27658/54. Class 38 (4). In a circuit comprising both a capacitively- and an inductively-stabilized gas and/or vapour filled electric discharge tube 1, 2 each having thermionic electrodes 11, 12 and 21, 22 connected to windings 13, 14 and 23, 24 of a heatercurrent supply transformer 8 whose primary winding 9 is serially connected with the stabilizing impedance 7 of the inductively stabilized tube 2 across the circuit supply terminals 3, 4, the capacitively stabilized tube 1 is serially connected with part of said stabilizing impedance 7 of the inductively stabilized tube 1 across the supply terminals 3, 4, and the heater-current windings 13, 14 of the capacitive tube 1 are connected in such polarity and are so dimensioned that the voltage set up across tube 1 is, prior to ignition, higher than that across the supply terminals, and the voltage set up across the tube 2 is not higher than that across the primary winding 9. Thus the capacitively stabilized tube 1 is caused to ignite first, whereupon its discharge current by flowing through the part of the inductance 7 increases the voltage across the inductively stabilized tube 2 which then ignites. The windings 13, 14 have more turns than the windings 23, 24 and during operation all the heater current secondary winding voltages are directed in the same sense as the operating voltage of the inductively stabilized tube 2. The positions of the elements 5, 6 of the capacitive ballast may be mutually reversed, and the tubes may be of the L.P. mercury vapour type having provided on their walls a fluorescent coating and an ignition electrode connected either to earth or to one electrode.

Abstract: 533,190. Pneumatic springs. SOC. ITALIANA PIRELLI. Oct. 16, 1939, No. 27985. Convention date, Oct. 17, 1938. [Class 108 (iii)] The resilient suspension for vehicles described in Specification 524,287 comprising in combination one or more pneumatic springs and one or more rubber springs so arranged that the rubber springs only come into play in the action of the system when the load sustained therein commences to exceed a given predetermined value, is modified so that the deformability and resilience of the suspension under load are adjustable during its functioning. In the preferred construction of the earlier specification wherein the rubber spring 2 is arranged within the pneumatic spring 1 comprising a bellows 5 closed by plates 3 and 4 which are affixed respectively to the suspended and the non-suspended parts of the vehicle, the pneumatic spring is connected to auxiliary reservoirs for the operating fluid of the spring by pipes 12, 14 provided with manually or automatically actuated valves 13, 15. The adjustability of the suspension is effected by opening or closing a valve thus softening the action of the springs or rendering them more resilient by the confined air respectively. In application to the landing wheels of a plane, the initial shock of landing is absorbed by closing the valve and the subsequent rolling load of the machine until it comes to rest is absorbed by thereafter opening the valve. Instead of connecting the pneumatic spring to a reservoir for the operating fluid at the point of change-over the rubber spring may be connected to atmosphere, the rubber spring taking the whole of the load. Two or more reservoirs of different operating fluid pressures may be used to allow the deformability and resilience of the suspension to be progressively regulated. The rubber spring may be constructed as described in Specification 440,925.

Abstract: A water-dilutable aqueous surface coating composition is obtained by reacting a novolak resin having units <FORM:1045715/C3/1> wherein Ar, RCH, and Y are, respectively, the residues of a phenol ArOH, an aldehyde RCHO and a drying or semi-drying fatty oil acid YOH, X is an alkylene group and n is 0-5, with an acyclic olefinic mono- or polycarboxylic acid having less than 10 C atoms in any chain, or an anhydride or monoester of such a polycarboxylic acid, and dissolving the product in an aqueous solution of a base.  Suitable novolaks of the above formula are described in Specifications 909,777 and 909,842.  The unsaturated acids are preferably dicarboxylic, e.g. maleic, fumaric, aconitic, itaconic, alkylmaleic and citraconic acids. Acrylic acid is a suitable monocarboxylic acid, and citric acid may be used under conditions producing itaconic acid or citraconic anhydride. Minor amounts of dienes, e.g. butadiene, cyclopentadiene, cashew nut shell oil, gum rosin, and myrcene, may be present.  Suitable bases are the alkali metal hydroxides, ammonia, and aliphatic amines.  An organic solvent, e.g. isopropanol, may be added to aid solution of the resin in the aqueous base.  The reaction may be conducted at 110-300 DEG  C., and the acid preferably amounts to 4-35 wt. per cent of the reaction mixture.  The coating composition preferably contains 15-16 grams of resin per 100 ml. of liquid, and may be cured at 100-250 DEG  C.  Usually a pigment is added.  In examples, phenol and formalin are condensed in the presence of oxalic acid, are ethoxylated, and esterified with soya or tall oil fatty acids, then heated with maleic anhydride.  The soya ester resin is thinned with butyloxyethanol and stirred with ammonia solution, while the tall oil ester resin is dissolved in aqueous ammonia and isopropanol. Films of these solutions containing cobalt driers are prepared and stoved.
