Title: Improvements relating to escape hatches
Inventor: DOLLERY GEORGE JOHN
IPC: E05B65/10
Filed: 1965-04-20
Abstract: 1,100,621. Emergency exits. HALLAM, SLEIGH & CHESTON Ltd. 19 April, 1966 [20 April, 1965], No. 16431/65. Heading B7B. [Also in Divisions E2 and F4] A roof escape hatch device for a building or a vehicle comprises an escape hatch panel 3 which is adapted to be mounted over an escape aperture 4 in the roof and which is associated with means for releasably retaining it against opening, said means comprising one or more members 9, 10 connected to said panel and releasably carried by one or more stationary attachment parts 11, 12 securable to the roof, the or each releasable member being engageable with a fastening part 15 for retaining said plate in place on the or the respective stationary attachment part, the said fastening part 15 being mounted on axially movable shaft 17 which is biased by spring means 26 towards an axially displaced position in which said shaft is disengaged from the bolting part, the shaft being normally retained against axial movement of said displaced position by a retaining element 21 which engages the shaft, said retaining element being, however, releasable from said engagement to cause the shaft to be quickly moved by the said spring means to its aforesaid displaced position whereby the fastening part is freed from the shaft and no longer retains the or the respective releasable member in place on the or the respective attachment part. In the construction shown there are two members, attachment parts, fastening parts and movable shafts and each shaft 17 in addition to being movable axially is also rotatable by means of a hand lever 19 to manually disengage the fastening part 15 from an aperture 16 in the respective member 9 or 10; each fastening part 15 has a square hole near one end by which it is engaged with a square section of the shaft 17. The retaining element 21 for each part 15 is pivoted near its inner end by a rivet 22 to the middle of the part 15 and has a hook-shaped outer end portion 21a which engages with a necked portion 17b of the lower end portion of the shaft 17 and so retains the part 15 in engagement with the square section of the shaft 17. Each element 21 is horizontally swingable out of retaining engagement with the shaft 17 by means of a cable 23 connected through a pivoted shackle 24 to the hook end portion 21a of the element; one cable is used for both elements 21 so that a pull on the cable releases both of the parts 21. When only one fastening part 15 is provided, the escape hatch is hinged at one end portion instead of being completely detachable as shown. As shown, casings 7, 8 are rigidly carried by the members 9, 10 and each casing contains a screw mechanism which is connected through front and rear linkages 5 and 6 to the escape hatch so that by operating the screw mechanism the panel 3 can be raised and lowered to enable it to serve as an adjustable ventilator.

Abstract: 694,715. Radiation pyrometer. ARMSTRONG SIDDELEY MOTORS, Ltd., and PARKER, A. June 21, 1950 [June 22, 1949], No. 16543/49. Class 40 (iii). A light sensitive cell used for temperature measurement feeds an electronic bridge operating a temperatureindicating instrument through valves fed in series from the light-sensitive device and has a grid/cathode return path which is independent of the lightsensitive device. The invention is described with reference to measuring the blade temperature of a gas-turbine engine. The photo-cell 11 which is mounted on a bracket 19 on the outlet manifold connected to the combustion chamber 20, "looks at " the fixed blading through a copper tube 14 which is gold-plated internally. A sealing window 16 of quartz is provided. The copper tube may be cooled by air fed through a surroundng jacket 22. The circuit arrangement is shown in Fig. 2. Photo-cell 17 in series with battery 32 feeds the grids of valves 28 forming arms of a bridge circuit across which is connected the measuring instrument 26. A separate grid cathode return path is provided for the valves through resistors R4, R5. To adjust the circuit the photo-cell illumination is reduced to zero and the meter reading brought to zero by means of coarse and fine resistors R7, R1.

Abstract: A devitrifiable glass, particularly for use in the form of beads or ballotini for blasting, comprises, by weight, 44-66% SiO2, 13-21% Al2O3, 4-35% CaO, and 5-15% MgO together, if required, with other ingredients which will not prevent devitrification by heat but excluding Li2O, the sum of the SiO2, Al2O3, CaO, and MgO constituting at least 85% and preferably 95% of the composition, the ratio SiO2 : Al2O3 being 3-3.5:1, and the ratio SiO2 + Al2O3 : CaO + MgO being 1.5-4:1.  The other ingredients may be Na2O and/or K2O up to 10%, and one or more nucleating agents such as TiO2, 3-15%, or Cr2O3, 0.5-5%. The heat treatment is carried out in two stages by first heating, e.g. at 3-10 DEG  C. per minute, to below softening point, and then, e.g. at 3-5 DEG  C. per minute, to above softening point, and then cooling.  Following each stage, the temperature may be retained for a period, and cooling can be carried out in two stages.  To prevent the beads from fusing together during heating, they may be embedded in powder, e.g. carbon, or suspended in a stream of inert gas.

The surface between layer 2 and plate 31 may be reflecting to cause illumination of the instrument dial surface 47A, and reflector 43 may also be included. Region 35 may include graphic markings formed by opaque material (not shown). The rear metallizations 13, 15, 17 of the dashboard in Fig. 2 may be selectively energized to form pilot lamps, and zones 21, 21A may be selectively energized to illuminate associated instrument dials in holes 19, 19A. Phosphor zones correspond to metallizations 21, 21A. A common conductor to zones 21, 21A effects simultaneous energization. Pilot lamps in the dashboard of Fig. 3 (not shown) include phosphor zones 5A, 5B, 5C, which may be differently coloured and corresponding to the graphic characters at the front surface. Reflector 7 increases the lamp efficiency. The phosphor may be serigraphically formed, and may be a paint, the support may be acrylic resin and overall layer thicknesses can be a micron to tens of microns.

IPC: C11C3/06
Filed: 1933-06-13
Abstract: Fatty esters containing unesterfied hydroxyl groups are prepared by reacting the triglyceride in a fat or fatty oil with a polyhydric alcohol in the presence of a catalyst comprising a soap of a metal of valence not greater than two.  The soap may be added as such or formed in situ by partial saponification of the fat with an alkaline compound such as trisodium phosphate, sodium carbonate, sodium bicarbonate or a caustic alkali.  In examples coco nut oil, cotton seed oil or a completely hydrogenated castor oil and glycerin are reacted in the presence of a sodium soap and completely hydrogenated cottonseed oil is heated with a solution of sodium hydroxide in glycerin.
