[Class 7 (iii).] A casing 1, flanged at its lower end for attachment to the engine, is provided in its recessed upper end with a plate 2 having four equidistantly-spaced channels 3-3<111>, the upper ends of which terminate in grooves of different lengths. Into enlargements of the lower ends of these channels are inserted tubes 5 the lower ends of which are fitted tightly into a member 6 secured by a bolt 7. A bolt 8 screwed into member 6 serves as an axle for a propeller 9 adapted to be actuated by suction and, through a pin 10, to rotate a disc 11 forced against the end of member 6 by a spring 12. The disc has an annular groove 11, Fig. 4, from which grooves 13 radiate to the periphery. In a depression in the upper face of plate 2 is a raw hide, fibre or like disc 14 having four equidistantly spaced channels 17-17<111> adapted to register more or less with the channels 3-3<111>. Above the disc is a plate 18 having channels 22 leading from channels 17-17<111> to a bore 23 to which fuel is supplied. A spring 20 is interposed between plate 18 and a cover 19 secured to the casing by screws 21. A ring 25 is dowelled to the cover 19 and is secured to the extension 24 of plate 18 by a set-screw 26. Air is admitted through ports 27 adapted to be controlled by tapering ports 30 in a sleeve 28. A ring 31 on the cover 19 which can be locked in position by a set-screw 32, carries a bolt 33 forming an axle for a bevel wheel 34 engaging another bevel wheel 29 at the upper end of sleeve 28. An arm 36 connected to the control system can, by means of a pin 37, be secured in different angular positions to the wheel 34.

Title: Improvements in or connected with latches or locks
IPC: E05B55/00
Filed: 1948-04-22
Abstract: 649,156. Night latches. WARSHAW, S. S. April 22, 1948, No. 11068. [Class 44] A latch or lock comprises a spring urged sliding bolt 1, Fig. 1, and two eccentric operating pins 3 and 2, Fig. 5, which are rotatable about the same axis and cooperate with the bolt 1, one pin being rqtated by a knob and the other by a key mechanism. Two spring urged pivoted levers 4, 5, co-operate with the pins 2, 3, the arrangement being such that the bolt can be caused to protrude further than the normal and be deadlocked by either pin coacting with its lever on operation either by the knob'or the key mechanism and the bolt 1 withdrawn from the deadlocking position only by the means by which the deadlocking was applied. The lever 4, which is pivoted at 6 on one side of the bolt and held against a fixed stop by a strong spring 9, is bent over the top of the bolt 1 to form an extension 4a passing across the other side of the bolt as far as the upper edge of the second lever 5 which is pivoted at 7 and pressed by spring 10 against a fixed stop. When the bolt 1 is projected by its spring 16 which is weaker than spring 9, the pins 2, 3, lie between the lever 4 and its extension 4a, and the ends of horizontal, grooves 19 which are formed in the .bolt and in which the pins normally move. Anti-clbckwise rotation of the button 11a, Fig. 1, journalled in the cover plate, by means of the bar of a cylinder lock forces the pin 3 to rotate the lever 4 and allow the bolt to protrude farther, usually # inch. The pin 3 enters a vertical groove in the bolt and is retained in deadlocking position by engaging a recess 18a in the lever 4. Similarly when the knob, which is attached to spindle 11 is rotated in the opposite direction to that required for retracting the bolt ,the pin 2 forces the lever 4 to rotate and allow the bolt to shoot further, and then leaving the extension 4a, the pin 2 engages a recess 18 in lever 5. If the bolt is retracted by the knob and whilst held back by finger, the knob is rotated fully 'backwards, a projection 21, on the spindle 11, reacts with a projection 22 which may be a lug integral with, or screw on, the bolt to hold the latter retracted. Springing the back plate to force the lock is prevented by forming, integral with the back case 8, a pair of slotted lugs 23 which Hold the back plate. To render the bolt reversible, grooves 20 are formed in the bolt 1 corresponding to grooves 19 and projections 22 may be formed on both sides. of the bolt. According to the Provisional Specification slots may replace the grooves.

[Also in Group XXI] Permeable mineral materials, e.g. building materials or petroleum bore holes, are rendered impermeable to liquids and gases by treatment with a liquid mixture of reactants which yield a cross-linked polymer thereby sealing the interstices. The mixture may be sulphuryl chloride with an unsaturated fatty oil or a butadiene or butadiene-acrylic polymer. Such mixtures may contain about 10% based on the total mixture of an inhibitor such as magnesium oxide, a mineral oil to reduce the viscosity, up to 10% of a silicone oil or resin, a swelling or foaming agent such as sodium bicarbonate or inorganic fillers such as chalk, talc, felspar or iron oxide. Acid soluble solids may be added and then leached out to render the sealing porous, e.g. magnesium oxide, lime or chalk. Another mixture is one yielding a cross-linked product containing -NH-CO-O- linkages and comprising a polyhydroxy compound containing at least three hydroxyl groups and a polyisocyanate. The polyhydroxy compound may be castor oil, the product of esterifying dicarboxylic acids with di- or tri-hydric alcohols containing at least three free hydroxyl groups e.g. the reaction product of adipic acid and glycol or glycerol, or a polyalcohol such as hexanetriol. The polyisocyanate may be toluidine di-isocyanate. A preferred mixture is of 1 gram molecule of castor oil with more than 2 gram molecules of toluidine diisocyanate which remains liquid for long periods, cross-linking being effected by adding further castor oil prior to use. Plasticisers and solvents may be added. Suitable plasticisers are phosphate, phthalate or adipinate esters, or butadiene-acrylonitrile polymers.
