Filed: 1926-11-03
Abstract: 282,938. Camm, S., and Hawker Engineering Co., Ltd., H. G. Nov 3, 1926. Steering, balancing, and regulating altitude.-In control mechanism for aeroplanes comprising a handwheel 2 for controlling the ailerons mounted in a horizontal bearing 10 at the upper end of a pivoted control column 13, a push member 5, 6 for firing a gun, is positioned relatively to the wheel 2 so as to be operable readily by the thumb or fingers without removing the hand from the wheel. As shown, the shaft 1 upon which the wheel 2 is fixed, is made hollow and slidable within it is a rod 3 on the rearwardly-projecting end of which is rotatably mounted a boss 4 carrying two radial arms 5 the outer ends of which are formed as thumb buttons 6 disposed a short distance within the rim 7 of the wheel 2. Guide pins 8 project forwardly from the buttons 6 through holes in the spokes or disc 9 of the wheel so that as the latter is. turned the arms 5 retain their relative position without rotating the rod 3. The forward end of the rod 3 is pivoted to one arm of a bell-crank lever 11 pivoted to a bracket 12 mounted on the column 13, the other arm of the bell-crank lever being connected by a. Bowden wire 14 to the gun mechanism, so that when the rod 3 is pushed forward by pressure on the buttons 6 the gun is fired. A returning spring 16 is provided. For locking or freeing the subsidiary control device, a fork 18, Fig. 3, slidable radially into and out of engagement with a recess 19 in the rod 3, is carried on a rod 21 which slides in a tube 22 mounted on the wheel 2 and terminates in a plate 23 located just within the rim 7 of the wheel so as to be operable conveniently by the fingers. The, rod 21 is held in its in and out positions by a spring-pressed ball 25. If the connection between the end of the shalt 3 and the bell-crank lever 11 comprises a ball and socket joint the arms 5 may be fixed directly to the shaft 3. The guide pins 8 may be dispensed with if in place of the two arms 5 several arms or an annular ring is used.

Patent GB-390533-A (GB)
Title: Process for the production of metal castings
IPC: B22D7/00
Filed: 1931-10-07
Abstract: To avoid undesired shrinkage of an ingot or other casting, the metal, while in the ladle or during or after pouring, is charged with a non-oxidizing gas, such as hydrogen, argon, helium, nitrogen, ammonia, or methane.  The metal may be first treated to prevent or reduce the liberation of oxidizing gases from the metal in known manner, as by adding silicon.  The casting is cooled at such a rate that the non-oxidizing gas is liberated and trapped therein thus producing a rimmed effect, unoxidized blowholes, which will easily weld up, and absence of pipe.  The gas may be introduced by means of a tube or by inserting a gas-evolving substance such as a hydrocarbon or sodium hydride.

Title: Improvements in earth resistance measuring instruments
Inventor: TAGG GEORGE FRANK
IPC: G01R27/18
Filed: 1953-10-13
Abstract: 724,888. Resistance measurements. EVERSHED & VIGNOLES, Ltd. Oct. 13, 1953, No. 28204/53. Class 37. An earth-testing instrument comprises a moving coil responsive to the voltage across test electrodes and a switch whose operation associates different measurement resistors with the said moving coil. In making a test two readings are taken corresponding to the two positions of the switch and if these readings are the same the operator is satisfied that no variation in electrode resistance has occurred. In the crossed-coil earth tester shown, operation of push PB removes the series limiting resistor P from the potential coil D circuit and replaces it by a smaller series resistor A and introduces a shunting resistor (e.g. a resistor S across A and D) having a magnitude such that when the resistance to earth of the two potential electrodes P1, P2 has a datum value the current through D is the same for either position of push PB and the two ohmic readings produced by deflection of coils D-C are therefore the same and indicate the specific resistance of the soil at X. If the second reading differs from the first a correction chart or calculator is used to obtain the value of the resistance X. Preferably the resistance of A + D is approximately one-half that of P + D. The tester may be used for measuring the resistance to earth of an earth plate or other electrode and may have several measuring ranges by provision of a corresponding set of resistors for each range together with the necessary switches.

A wheeled vehicle is towed in a mechanical garage by a trolley 1 (Fig. 1) formed with a surface which can be inserted under the leading or trailing wheels of the vehicle and on which the wheels are retained to provide the towing connection. As illustrated the trolley has a hump 4 which is pushed under the front wheels of a vehicle while the vehicle is held at rest until the wheels engage a stop 10. The hump 4 is divided in two by a central channel (Fig. 2] and is provided with guiding flanges 8. The trolley may rock about a central wheel 5 on to either of two rollers 6, 7 so that the slope of the portion 3 of the surface of the trolley is increased after the wheels of the vehicle have passed on to it. The trolley may be pulled into and out of a lift cage 13 (Fig. 4) by a telescoping hydraulic ram, by a lazy tongs linkage, or by the screw and nut 18, 17 illustrated which act through a lever 15 which is caused by abutments 22, 23 at the ends of its path of travel to turn about a pivot 16 on the nut 17 to increase the travel of the trolley 1. The floor of the garage adjacenb the lift is preferably formed with rollers 24 (Fig. 7) which facilitate the passage of the trolley 1 under the wheels of the vehicle. Rollers 28, 30 are turned about vertical shafts 29, 31 to chock the vehicle wheels under the control of limit switches or the like operated by the movement of the trolley 1. The rollers 28, 30 are caused to rise and fall during the motion of the trolley 1 so that they describe a path parallel to its surface. Each of several lifts 13 (Fig. 10) may serve a number of storage floors each provided with a platform 39 mounted by rollers 40 to run on rails 38 so that any of several compartments on each platform may be brought into register with any of the lift gates.
