Abstract: 859,627. Discharging missiles from aircraft. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION.]. March 25, 1959 [March 28, 1958], No. 10396/59. Class 9(2). [Also in Group XXXIII] A releasable clamp 14, having two arcuate arms 16, 18 and a hook type latch 20, for attaching a booster (not shown) to an aircraft, is held engaged by a displaceable member 35, which extends from a fluid pressure actuator 38, supplied by a low pressure feed pipe 42 and a circuit containing a ball valve 58 which responds to acceleration forces on the aircraft, varies the pressure applied to the actuator, and displaces the said member to disengage the clamp, thereby releasing the booster. When the clamp is engaged during the acceleration phase both faces of the piston 36 in the actuator are supplied with high pressure fluid through the valve and conduits 46, 44. In operation, with the reduction in acceleration after the boost phase, the deceleration forces acting on the slidable weight 62 in the valve mechanism become insufficient to hold the ball off its seat against the spring 60 and the valve closes, shutting off the high pressure conduit 46 and causing the member 35 to disengage from the clamp.

Title: An improved process for making formaldehyde and other oxidation products from hydrocarbons of the paraffin series having more than one carbon atom in the molecule
IPC: C07C45/33
Filed: 1935-04-08
Abstract: Paraffin hydrocarbons containing two or more carbon atoms, such as ethane propane and butane are converted into formaldehyde and other oxidation products such as acetaldehyde, methanol, and formic acid, by passing the hydrocarbon in the absence of methane, together with oxygen or air and about 1 per cent or less of nitrogen oxide, at 500--800 DEG  C. over solid catalysts consisting of one or more of the elements of Groups II and IV of the Periodic System or their compounds alone or together with at least one of the elements chromium, vanadium, molybdenum, aluminium, tungsten and nickel or their compounds.  In examples: (1) ethane is oxidized at 675 DEG  C. by means of a catalyst consisting of 98 parts SiO2, 1,5 parts MgO and 0,5 parts Al2O3 yielding formaldehyde and acetaldehyde; (2) butane is oxidized at 710 DEG  C. by means of a catalyst consisting of 80 parts MgO, 10 parts Al2O3, 5 parts CaO and 5 parts SiO2, yielding formaldehyde, methanol, and acetaldehyde; (3) propane is oxidized at 685 DEG  C. with the catalyst of example 1, yielding formaldehyde, acetaldehyde, and formic acid; (4) example 1 is repeated at 25 atmospheres pressure with higher yields. Specifications 337,407, [Class 2 (iii)], and 433,559 are referred to.  The Specification as open to inspection under Sect. 91 includes boron in the list of elements used as catalysts, and mentions other catalysts in the examples, as follows: (1) 85 parts Al2O3, 10 parts MgO, 5 parts MnO; (2) 92 parts MgCO3, 2 parts CeO2, 5 parts CaO, 1 part MoO3; (3) 60 parts BaO, 10 parts NiO, 20 parts SiO2, 10 parts Fe2O3.  The proportions of hydrocarbon and oxygen, the temperatures, and the pressure in example 4 are also somewhat different.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to control means for servo-operated gear-change mechanisms
IPC: F16H61/40
Filed: 1957-04-03
Abstract: 821,890. Change-speed control. DAIMLERBENZ A.G. April 3, 1957 [April 4, 1956], No. 10909/57. Class 80 (2). In an automatic gear-shift control responsive to engine-speed, accelerator and service brake operation, automatic downshift produced by service brake operation is permitted only below a predetermined low engine speed. A floating lever 2, pivoted at its opposite ends to an engine-driven governor 3 and accelerator-pedal 1 respectively, centrally operates contacts 5, 6, energizing respectively upshift and downshift lines J UP and J DOWN, so that the engine speed at which upshift occurs is increased with increased accelerator depression, and also upshift and downshift can be produced by part release or depression respectively of the accelerator pedal. A contact 8, closed by pressure in the service brake system, independently energizes the downshift line J DOWN, providing engine speed is below a predetermined low value at which a second engine-driven governor closes a series contact 7. The same contact 7 also opens the circuit from the automatic downshift contact 6, to prevent automatic downshift above the said engine speed. A manual over-ride switch 16 can be rocked in either direction to close upshift or downshift contacts which produce shifts in preference to the automatic control due to resistors 19, 20 in the lines of the latter. A switch 14, opened on complete release of the accelerator 1, opens the upshift circuit to prevent automatic upshift by such release. Opening a switch 22 cuts out all automatic action except that of the service brake contact 8. Fig. 1 (not shown) omits the manual override 16, switches 14, 22 and resistors 19, 20. First, or first and second ratios may be excluded from the automatic control, and the gear may be driven through a torque-converter.
