Patent GB-848806-A (GB)
Title: Brake control system
Inventor: HEMPHILL STANLEY RICE
IPC: B60T11/10
Filed: 1958-03-21
Abstract: 848,806. Controlling vehicles. SAFETY AUTOMATIC BRAKE CORPORATION. March 31, 1958, No. 10298/58. Class 79(5). [Also in Group XXXIV] In a motor vehicle the accelerator pedal 40, Fig. 1, has a lost motion connection with the throttle 3 and is connected by a rigid linkage with a brake control valve 20 so that as the pedal is depressed the brakes are gradually released before the lost motion is fully taken up and the throttle begins to open. The pedal is pivoted at 41 and connected by links 42, 43, 44 with an actuating lever 97 on the valve 20, a bracket 44b secured to the link 44 and a pair of stops 45x on a link 45 forming the lost motion connection to the throttle. When the vehicle is standing still and the engine idling, suction in the engine manifold 2 is transmitted through a pipe 21 to a chamber 55 in the valve 20 and through pipes 22 and 23 to booster cylinders 15 and 16. The cylinder 15 applies the service brakes 5..8 through a linkage 17, 18, a master cylinder 14 and hydraulic connections 12, 13 while the cylinder 16 releases emergency brakes through a pull rod 39, a lever 33 and cables 30-30. A hand lever 35 for operating the emergency brakes is connected to the lever 33 by a cable 36 and a spring 37 which permits the cylinder 16 to release the emergency brakes even when they have been applied by hand. To start the vehicle moving, the pedal 40 is depressed to rotate the lever 97 and a cam 95, Fig. 3, secured thereto, the cam follower 93 and a slide 82 being displaced to the left to reduce the pressure applied by a spring 87 to a diaphragm 54. The latter is pulled to the left by the suction in the chamber 55 so that a valve 76 is closed by a spring 77 to trap the vacuum in the cylinder 16 while a valve 68 isolates the chamber 55 from the suction in the pipe 21. Air entering through a filter 50, slide 82, a port 66<SP>1</SP>, and the space between the valve 68 and its seat 67, enters the pipe 22 through a hole p in a valve 79 to release the service brakes gradually. Loss of fluid from the cylinder 14 causes an arm 125 to depress a valve 120, Fig. 6, and admit air through ports 118 and 119 to the cylinder 16 so that the emergency brakes are applied by the spring 37. Simultaneous closure of a port 124 prevents loss of vacuum in the chamber 55. The pedal 40 may be held in any set position by a pawl 133 and a toothed wheel 130 which are brought into engagement when a solenoid 132 is energized by closure of a switch on the instrument panel of the vehicle. Closure of the horn circuit may be arranged to energize a second solenoid whose core strikes that of the first solenoid to release the pedal 40 in an emergency. In a modified construction the booster cylinder 15 and the master cylinder 14 are coaxial and form a unit to which the valve 120 is secured. The latter is of modified construction and includes a lost-motion connection to seal the chamber 55 before the cylinder 16 is opened to atmosphere.

Title: Improvements in or relating to nitrocellulose preparations
IPC: C06B23/00
Filed: 1947-04-18
Abstract: Nitrocellulose of the kind soluble in liquid explosive nitric esters is impregnated, while in the uncolloided condition, with a solution comprising at least 30 per cent by weight of a mixture of ammonium nitrate and urea in approximately binary eutectic proportion in an aqueous alcoholic solvent substantially richer in alcohol than in water, e.g. of 60-70 per cent alcoholic strength, the amount of water being not more than 20 per cent of the weight of the nitrocellulose, and the amount of the solution being sufficient to maintain the nitrocellulose in moist condition.  The treatment reduces the risk of explosion during storage or handling and removes difficulties of mixing met with when using nitrocellulose moistened with water only or with aqueous alcohol only.  The weight of solution employed may be 0.9-1.3 times the weight of the uncolloided nitrocellulose.  The binary eutectic composition consists of 53 per cent ammonium nitrate and 47 per cent urea.  Water wet nitrocellulose may be treated with a strongly alcoholic aqueous solution of the ammonium nitrate and urea mixture until the water is displaced.  Preferably, the water in the water wet nitrocellulose is first displaced with alcohol and the alcohol is then displaced by the aqueous alcoholic solution of ammonium nitrate and urea, or a strong aqueous solution of the mixture may be added to the spirit wet nitrocellulose without rejection of any liquor.  The prepared nitrocellulose may be mixed with nitroglycerine and other substances to form explosive compositions (see Group XXI).

Abstract: 657,689. Helicopters. KRAUSS, S. J. May 17, 1949, No. 10880/48. [Class 4] A helicopter comprising two or more blades rotating in the same sense and in a normally substantially horizontal plane in which each blade is permitted a limited amount of flapping movement is characterized in that all of said blades are rotated about a common point by a power driven mechanism which comprises for each blade two elements capable of exerting on the blade mutually dependent forces, the lines of action of which are contained in substantially rectangular planes. The drawing illustrates the mechanism for one blade only, wherein each blade is extended by a crank A which terminates in a sleeve B, a fork G rotatably and slidably mounted on the root end of the blade being pivoted on an axis X to a second fork H fast with a hollow shaft F. A further shaft E, coaxial with the shaft F, carries a stirrup mounting for a crank D inclined in a plane containing the vertical axis Z and the horizontal axis X and slidably mounted within the sleeve B, the crank being angularly adjusted in the aforementioned plane by a control mechanism C. The shafts E and F are driven in the same direction by an engine K through a mechanism J1-J10, contained within the fuselage L. The drive mechanism comprises a bevel gear J1 driven by the engine K and meshing with gears J2 and J10. The gear J10 is fast with another gear J9 which in turn meshes with a pinion J8, the bearings supporting all of these gears being fast with the aircraft structure. A positive drive is provided between the engine K and the shaft E by the gears J1, J10, J9, J8 and a gear J7 fast with the shaft E, rotation of which causes combined flapping and pitch change movement of the blade A if the blade is held fast at any cyclic position, the magnitude of such movement being determined by the angular deflection of the crank D. The gear J2 carries a planet carrier J3 having pinions J4 freely pivoted thereon and engaging one gear J6 fast with the shaft E and another J5 fast with the shaft F. The arrangement of gears is such that under normal conditions of flight when the aerodynamic forces acting on the blade in the vertical and horizontal planes are balanced respectively by the loads exerted on the crank D through the shaft E and on the stirrup H, G through the shaft F, no relative motion takes place between the shafts E and F which rotate in the same direction. Under such conditions, the angular relationship of the crank D and the resolved aerodynamic force exerted on the blade A with a plane containing the axes Z and Y is the same. Should these conditions be disturbed either by external aerodynamic forces acting on the rotor system or by manual adjustment of the control mechanism C relative rotational. movement will take place between the gears J5 and J6 and consequently, between the shafts E and F, to vary the attitude of the blade in the flapping and/or pitch change sense to restore the conditions of equilibrium.
