[Also in Groups XXIX and XXXIII] In a jet deflecting arrangement for gas turbine power plant the jet pipe 2 is secured to a Tee piece 4 which comprises a main portion fastened to the tail pipe 5 and a branch portion which terminates in a nozzle 6 which may be directed downwardly or, as shown, downwardly and rearwardly. Butterfly valves .37 and 39 are secured respectively to spindles 38 and 40 pivotally mounted in the main and branch portions of the jet pipe. The spindles are connected for simultaneous movement by gears 41 and one spindle carries a lever (not shown) connected to an operating mechanism (not shown) which may be hydraulic, incorporating hydraulic locks to hold the valves in almost-shut positions in which they do not jam within the Tee piece 4. In an alternative embodiment (Figs..2 and 3, not shown), the valves are mounted on substantially horizontal parallel pivots each provided with an operating lever, the levers being interconnected for operation by an hydraulic actuator. The valve in the branch pipe is preferably curved and formed with a similarly curved guide vane to direct the flow of gases in a downward direction. The pivot pins for the valves may be hollow and connected to a source of cooling air, preferably tapped from an engine compressor, and the valves may have hollow interiors supplied with cooling air through apertures in the hollow pivot pins, the walls of the valves being slotted to enable the cooling air to escape into the jet stream.

Abstract: 735,039. Flow-boxes of paper-making machines. PAPER PATENTS CO. Nov. 14, 1951 [Nov. 21, 1950], No. 26658/51. Class 96. Paper pulp, under hydrostatic pressure, from a flow spreader &c. is received at an inlet 45 stirred by a cylinder 81 rotated, e.g. at up to 3500 feet per minute by a motor 111 &c. and delivered to the wire-cloth 11 of a Fourdrinier machine above, e.g. an open type breast roll 137 where the fibres are felted before passing under a slice plate 118. The cylinder 81, which may be smooth or rough, and imperforate accelerates the stream of pulp, e.g. to the wire speed, the upper boundary layer of the stream being re-circulated in a compartment 79, and the lower boundary layer flowing backwardly over the breast roll. The bearings of the roll 81 are mounted eccentrically in eccentric mounted plates in the walls of the flow box to provide for adjustment of the roll 81, the sliceplate 118 being adjustable by screws 127, a table-plate 115 being adjustable and clamped by screws 10, and the breast roll 137 which may be slatted (143) and have suction compartments 150, 151, 152 exhausted at 166 &c. and compressed air compartments 148, 149 supplied at 161 &c. may be adjustable and the compartments 148 ... 152 &c. circumferentially adjustable. White water is doctored off at 211, and a tray (not shown, Fig. 9) under the upper run of the wire-cloth returns white water to the pulp-mixing tank which supplies the flow-box through an automatic pressure-regulating valve. The flow-box may be used in cylinder papermaking machines. Specifications 457,940, 701,581 and 705,665 are referred to.

[Class 44] A door fastening, particularly for use on motor vehicles, comprises a casing 10 fixed transversely on the edge of the door 12 and provided with converging upper and lower faces 13, 14 which engage with a wedge action in a correspondingly shaped keeper 40 mounted on the fixed post 41, a catch projecting from one of the converging faces to retain the case in the keeper. As shown, the catch comprises a spring strip 21 conforming with the inner wall of the casing and secured thereto at 22, the free end 47 of the spring being bent downward to project through an aperture in the wall 14. Secured to the spring is a strip having a bowed nose portion 19 projecting from the casing, and a vertical limb 20 with inturned upper end 23. Nose 19 snaps over a lip 46 into a recess 45 in the casing, end 47 acting as a safety catch when the door is not fully closed. Release is effected from outside by handle spindle 27, Fig. 4, with boss 25 and follower arm 26 engaging projection 23 to lift nose 19 on clockwise rotation of the spindle. Anticlockwise rotation of spindle 27 is limited by an arm 33 on boss 25 engaging a lug 37. Release from inside is effected by handle spindle 31 with boss 29 and follower arm 30 adapted, on clockwise rotation, to engage and lift arm 26. An arm 36 on boss 29 engages, on reverse rotation of spindle 31, under arm 33 to prevent release by the outside handle. A spring 38 has a rounded portion adapted to snap into either of two recesses in boss 29 to retain spindle 31 against accidental movement from either of its two operative positions. Spindles 27, 31 are disposed close to the edge of the. door to give maximum clearance for the usual vertically-sliding window. A modification is described using a pivoted spring-biassed pawllike catch adapted to engage one of two recesses in the lower wall of the keeper, the first-engaged recess giving a safety catch action.

Abstract: The Specification comprises mixtures of at least three position isomers of dicyclohexyl alkanes of the formula <FORM:0960590/C4-C5/1> these compounds are obtainable by hydrogenation of the corresponding aromatic compounds <FORM:0960590/C4-C5/2> the compounds <FORM:0960590/C4-C5/3> and <FORM:0960590/C4-C5/4> being formed as intermediates; in the above formulae R1 and R2 are C1-C13 alkyl groups, Y is a C1-C13 alkylene or alkylidene group, m is 1, 2 or 3, n is 1, 2, 3 or 4, and <FORM:0960590/C4-C5/5> denotes a cyclohexane ring.  The aromatic compounds IV are themselves formed by bridging two benzene-ring hydrocarbon molecules, at least one of which is an alkyl benzene, with an alkylene group by reacting with an alkyne, aldehyde, glycol, alkylene oxide, dichloro-, dibromo or chlorobromo-alkane or a C3-C13 diene.  Using a singel alkyl benzene R1 and R2 will be the same; when different alkyl benzenes are employed, mixtures of compounds are obtained.  Higher molecular weight compounds of formula <FORM:0960590/C4-C5/6> or <FORM:0960590/C4-C5/7> formed, where p is 2 or 3, may be hydrogenated with the other products or removed by distillation. Alternatively or in addition, diphenyl alkanes or di-alkylphenyl alkanes may be alkylated; the formation and alkylation of the di(alkyl)phenyl alkanes may be effected simultaneously. In forming the dil(alkyl)phenylalkane, a mol. ratio of alkyl benzene to bridging compound of 2-3 : 1 is used, where higher molecular weight compounds are desired a lower ratio, e.g. 0.5-3 : 1 is used. Hydrogenation may be effected at 500-5000 p.s.i. and 100-200 DEG C. in the presence of Raney nickel and a diluent, e.g. a paraffin.  Fuels for jet, turbojet, rocket or missile engines comprise mixtures of 25% or more of the above mixtures of isomers with kerosene, dialkylcyclohexane, cumene, hydrogenated cumene, di-cumene, hydrogenated di-cumene, paramenthane, boron hydride, decaborane, alkyl boron hydrides and trialkyl boranes.
