Title: Method of forming adhesive bonds between surfaces
IPC: C03C27/10
Filed: 1972-08-11
Abstract: 1373559 Cyanoacrylate adhesive; bonded laminates INTERCONTINENTAL CHEMICAL CO Ltd 11 Aug 1972 [11 Aug 1971] 37493/72 Heading B5N [Also in Division C3] Adhesive bonds are formed between surfaces, particularly glass to glass or glass to rubber, using an adhesive composition containing at least one monomeric ester of 2-cyanoacrylic acid, in conjunction with at least one alkoxy or acyloxy silane of the formula X 3 Si(CH 2 ) n Y in which n represents an integer from 0 to 3, X represents a methoxy, ethoxy, methoxyethoxy, acetoxy, propionoxy, n-butyroxy or isobutyroxy group, and Y represents a chlorine atom or a vinyl, methyl, trichloromethyl, mercapto, 3,4- epoxycyclohexyl, glycidyl or amino group, or alternatively X represents an allyl group and Y represents a methoxy, ethoxy or methoxyethoxy group. The silane may be incorporated in the adhesive composition or may be applied separately in the form of a primer solution. The adhesive compositions containing the silane are novel but, in such compositions, the group represented by Y in the formula above cannot be a 3,4-epoxycyclohexyl, glycidyl or amino group, because such a silane is incompatible with the adhesive composition. The bonds formed have appreciable resistance to degradation in water and high humidity conditions. Exemplified silanes are triacetoxyvinyl silane, triethoxyvinyl silane and ethoxytriallyl silane, and methyl cyanoacrylate is exemplified as a cyanoacrylate. When used as a primer, the silane may be dissolved in water or a chlorinated hydrocarbon solvent. The cyanoacrylate adhesive may contain conventional thickeners and stabilizers.

Title: Control of screech in combustion chambers
IPC: F02C9/28
Filed: 1957-12-11
Abstract: 824,821. Gas turbine plant; jet propulsion plant. UNITED AIRCRAFT CORPORATION. Dec. 11, 1957 [Dec. 14, 1956], No. 38488/57. Class 110 (3). [Also in Group XII] A combustion chamber 14, particularly a reheat combustion chamber or a ram jet unit combustion chamber, which is susceptible to high-frequency oscillatory combustion commonly known as screech combustion, includes a pair of spaced-apart passages 30, 32 leading from the duct, one of the passages, 32, being shaped to provide a high gas discharge coefficient out of the chamber and a low gas discharge coefficient into the chamber, and the other passage, 30, being shaped to provide exactly opposite conditions to the first, a pair of chambers 40, 42 being provided each communicating with one of the passages 32, 30 respectively, also means for sensing the pressure differential between the two chambers. Fuel is supplied to the combustion chamber through duct 16, shut-off valve 18 and duct 20 to a ring manifold 22 having ejectors 24 and ignition is provided by means of igniter 26. Pressure pulsations in the chamber will result in a tendency for gas to accumulate in the chamber 40 through the passage 32 and for gas to be expelled from the chamber 42 through the passage 30. An average pressure differential which is proportional to the amplitude of the pressure oscillations is thus set up between the chambers 40, 42. When the pressure differential reaches a predetermined value, the diaphragm 44 between the chambers will be deflected so that its contact 46 will engage either the contact 48 or 50 thereby closing the electrical circuit through solenoid 56 and so causing the valve 18 to close, thereby cutting off fuel supply to the combustion chamber. The warning device 60 will operate at the same time. A warning device only may be provided so that fuel supply may be cut off manually.

A lock housing 1 is pivoted about a pivot 2 to lie against an attachment plate 3 and engage a hasp and notches on either side of a bolt 5. The locking slider 8 has the offset tang 27 which in locking position engages an aperture 29 in the plate 3. To release the lock the combination is set by the knobs 17 and a projecting tongue 9 of the slider is pressed to disengage the tang from the plate and allow the housing to pivot to release the hasp. When the lock is operative levers 24, Fig. 9, pivoted to the base of the housing urge a safety bolt 20 to engage in an aperture in the slider 8 against the pressure of a spring 22 to lock the slider. When the combination is set, Fig. 5, the levers abut flats on the sides of the locking wheels and the safety bolt disengages the slider under the pressure of the spring to allow the slider to slide. The knobs 17 frictionally engage the locking wheels and both move together until the combination is set when the locking wheels are held stationary by the tangs of the slider, the knobs may then be moved relative to the locking wheels to change the combination by overcoming the friction between the knobs and stationary locking wheels. Each locking wheel has a stud 12' which pivotally engages in an aperture in the base 4. Each locking wheel has a friction head 15 which engages in a recess 16 and the knob 117, the knob has a rim 17' which displays the digits and these are visible through windows 31 in the housing.
