Title: Improvements in or relating to the manufacture of glass fibre synthetic resin laminates
IPC: C03C25/34
Filed: 1944-06-05
Abstract: 586,793. Laminated material. THURSTON, A. P. June 5, 1944, No. 10755. Convention date, Oct. 4, 1943. [Class 140] In producing glass fibre synthetic resin laminates by applying a urea type resin to the glass fibres and curing, the glass is first treated with a compound giving an acid under the heat required for curing the resin to catalyse the curing. For urea formaldehyde resins, the compounds comprise ethyl silicate, diethyl silicate, diethyl sulphate dissolved in alcohol and ethyl, methyl or phenyl silicon trichloride dissolved in toluene or Stoddard solvent. The glass may be in the form of intermatted webs or mats or in the form of woven fabrics. The glass is first cleaned by heating to 600 or 700‹F. for several hours, or washed by boiling in a detergent such as Aerosol. The mats or fabrics are then coated by spraying or dipping and dried, and immediately or later the urea resin is applied and cured by heat, several sheets being laminated.

Title: Production of dibenzanthrone and isodibenzanthrone
IPC: C07C45/72
Filed: 1930-04-04
Abstract: Dibenzanthrone and isodibenzanthrone are obtained by fusing benzanthrone and halogenbenzanthrones with caustic potash in the presence of liquid alcohols or aldehydes derived from furane; according to examples dibenzanthrone is produced by the potash fusion of benzanthrone in presence of furfural and furfuryl alcohol, and isodibenzanthrone by the fusion of chlorbenzanthrone in presence of furfural.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of heterocyclic carbonyl compounds in general, including condensation products of furane derivatives with aliphatic ketones.  This subject-matter does not appear in the Specification as accepted.

The brake shoes 34 are contained between the flanges 31 of the fixed brake plate 62 and are guided to move radially by slots and pins 39 passing through the flanges 31. The inflatable tube 33 of rubber is arranged at the base of the channel between the flanges 31 and extends into undercut recesses in the flanges, Each shoe is provided with a surfacing 43 of asbestos &c. and with a lining 35 of canvas between itself and the tube 33, the linings of adjacent shoes extending into interlapping engagement. The linings assist in insulating the tube 33 against heat and also prevent it from being pinched between the shoes. Springs 42 contained in slots in the shoes and engaging the pins 39 return the shoes when the tube is deflated. A compressor actuated from the transmission delivers air or other fluid under pressure to an accumulator from which it may be supplied through pipes 46 to all four-wheel brakes simultaneously by a single control valve. The compressor may run continuously, relief valves being provided in the accumulator.

Abstract: 801,979. Friction clutches. GENERAL MOTORS CORPORATION. April 5, 1957 [April 19, 1.956], No. 11169/57. Class 80 (2). In a multi-plate clutch for use in an automatic transmission, the plates 26 of one set, preferably the driven set, are of plain metal with axially aligned radial undulations, whilst those 34 of the other set are flat and have cemented friction facings 38.

Abstract: 1,222,554. Detecting signals between amplitude limits; television; cathode-ray tube display. BOFORS A.B. 7 March, 1968 [3 April, 1967], No. 11237/68. Headings H3T, H4F and H4T. A television receiver has means for brightening or darkening that part of the image which is within a predetermined amplitude range, said means comprising a first amplifier indicating when the video signal is above a first level, a second amplifier indicating when it is above a second level, the brightening being effected when the first indication and not the second is present. If the video signal input at I rises above a negative threshold determined by resistors R18, R19, a comparator transistor T3 becomes conductive cutting off T4 and thus through R17 changes the state of a Schmitt trigger T8, T9. If the input rises above a positive threshold determined by R21, R24, a comparator transistor T6 is cut off rendering T7 conducting and thus causing T5 to short the input to the trigger which accordingly restores to its initial state. Diodes D11 and D12 limit the input to the two comparators. The input signal is applied to input I via an operational amplifier (Fig. 3, not shown) arranged to enable the D.C. level of the input signal to be varied so that different regions of the signal amplitude range fall within the range between the positive and negative thresholds. The circuit is described as used in a television system (Fig. 1, not shown) for scanning the human body to produce a thermographic display and for super-imposing peak a white or peak black signal upon the video input to CR tube when the temperature is within the aforesaid range (Fig. 1, not shown). A mirror scanning system directs the image on to an infra-red sensor of I n S b  maintained at the temperature of liquid nitrogen.

A brake cylinder pressure limiting valve is controllable to a first position in which the setting is proportional to the vehicle load and to a second setting in which the setting is constant. The valve comprises two diaphragms 12, 13 urged apart by a spring 14, the diaphragm 13 having a central tubular member 15 venting to atmosphere, through chamber 21 and vent 22, at its upper end and co-operating with a double valve 16, 18 in the circuit between a brake cylinder pipe 19a and a brake pressure supply pipe 20. The space 23 above the diaphragm 12 is connected to an electromagnetically-operated twoway valve 25 which opens space 23 either to atmosphere through passage 26 or to a passage 28 having a continuous supply of fluid, the pressure of which is proportional to the vehicle load. The valve may be used with the fluid system of a composite fluid and dynamic braking system and under normal conditions the valve 25 opens space 23 to atmosphere and diaphragm 12 is against stop 29 allowing the spring 14 to act on diaphragm 13 which co-operates with the double valve to produce a lap condition of the valve 16, 18 allowing a reduced braking pressure from passage 20 to be maintained in the brake cylinder passage 19a. Should the dynamic brakes fade or fail, the valve 25 is automatically changed over to provide a load proportional pressure above the diaphragm 12 which fully closes spring 14 and the valve 16, 18 then provides full braking pressure proportional to the vehicle load. The valve may be used with pressure or vacuum braking systems.
