Title: Improved control system for variable pitch propellers
IPC: B64C11/42
Filed: 1953-02-27
Abstract: 724,686. Variable-pitch propellers. GENERAL MOTORS CORPORATION. Feb. 27, 1953 [Feb. 28, 1952], No. 5493/53. Class 114. The operating pressure for reducing pitch is restricted by the relief valve 25, but this pressure is increased for movement in the direction of increasing pitch by loading the valve by fluid pressure from the operating line 31. Pressure fluid from the pressure reducing valve 7 is led by the speed sensitive valve 3 to either of cylinders 103, 104 moving the distributing valve 5. To maintain a pitch position flow continues through the high pressure line by a constant leak through orifice 40. To feather, the control ring 170 is moved to the position F, moving the plunger 84 and so bringing the valve 5 to fully open port 118. At the same time the pilot valve 158 is unlatched to release fluid pressure from the accumulator 138 if required. For braking, the ring 171 is moved to the position N, this simultaneously shifting the sleeve 94, and so moving distributing valve 5 to connect ports 116, 117, whilst unlatching the pilot valve 158 to release accumulated pressure. Link 76 lifts the plunger 63 for ready restoration of the speed governor in the positive pitch range. Specifications 544,580, 545,520 and 598,707 are referred to.

Abstract: Boric oxide (as acid or anhydride) is nitrided, by heating in an atmosphere of ammonia, in a plurality of stages, additional boric acid being added between each stage and the initial boric oxide being in admixture with a diluent.  "Stabilizing" diluents specified are calcium and magnesium phosphate and oxide. Non-stabilizing diluents specified are calcium borate and granular alumina.  Usually at least one third of the initial mix should be diluent.  Boron nitride containing 5-10 per cent of diluent can be made in about 6 successive nitriding steps using an initial mix containing 50 per cent of diluent.  The intermediate reaction product may be milled to fine particle size, e.g. at least 10 microns before addition of additional boric oxide. Milling may be effected after every second or third nitriding step.  Nitriding is preferably effected at 800-1100 DEG C. but may be carried out at 500 DEG C. if subsequent washing is not necessary.  In the example 8 nitriding steps produced a product containing 6.4 per cent tricalcium phosphate and a density of 2.21. Use boron nitride produced may be washed with hydrochloric acid and then hot pressed or may be hot pressed without washing.  Hot pressing may be carried out at 1500-1900 DEG C. preferably at a pressure of 400 p.s.i. but pressures as low at 250 p.s.i. may be employed.  The pressed body may have a compressive strength of 40,000/50,000 p.s.i., an apparent density of about 2 gm./cc. and a sand blast penetration of 0.005-0.010 in.

[Also in Group XVI] In a power-operated machine similar to that described in Specification 525,288, which is referred to, for performing cutting-out and/or embossing operations on workpieces, e.g. shoe parts, a wedge block 99 is provided for disengaging a clutch bolt 77 to bring the machine to rest while a tool of the machine is in engagement with a workpiece, the wedge block being carried by a pivotally-mounted lever 95 so as to be movable to an inoperative position by means of a manually-operable change-over lever 205 whereby the machine can be brought to rest, by means of a wedge block 81 disengaging the clutch bolt, only after the tool and workpiece have been separated, the wedge block 81 being carried by a lever 211 pivoted on the same fulcrum 213 as the clutch-operating lever 83, and the lever 211 having pivoted thereto at 217 a latching member 215 engageable with a catch plate 219 fixed on an extension of the lever 83, the latching member being provided with an arm 221 carrying a follower roll. 223 engaging a cam 225 formed on the boss 75. A spring 207 retains the lever 95 in either its operative or inoperative position. When the starting treadle is depressed, the lever 83 is moved in an anticlockwise direction imparting a similar motion to the lever 211 which at this moment is coupled to the lever 83. The movement of the lever 211 carries the wedge block 81 out of engagement with the clutch bolt thus setting the machine in motion. Almost immediately, the latching member 215 is released and this allows the lever 211 to be swung back by means of a spring 227 to bring the wedge block 81 into position to engage and withdraw the clutch bolt when a full cycle of the machine is completed although the treadle may still be in a depressed position. When the lever 95 is in the operative position to cause the machine to stop after completing only half a revolution, the machine is re-started by releasing the starting treadle to move the wedge block 99 out of engagement. This is effected by moving the lever 83 in a clockwise direction to disengage the lever 95 by means of the rod 101.
