IPC: B66C23/90
Filed: 1966-04-20
Abstract: 1,082,786. Safe load indicators for cranes.  RUSTON - BUCYRUS  Ltd. April 20, 1966 [April 22, 1965], No. 17201/66. Heading B8B. [Also in Division G1 A safe load indicator for a jib-crane has a graph board 32 in the cabin over which moves an electrode controlled by the jib inclination and the load and the graph board supports an electrically conducting curve representing combinations of boom angle and load corresponding to a predetermined maximum moment so that when the electrode contacts the curve a warning signal is operated. The jib angle is measured by a device 29 which includes a pneumatically damped pendulum and a potentiometer to provide a proportional electric signal. The load is measured by an hydraulic diaphragm type of load cell which is located in the middle run of a suspension tackle 20 to eliminate frictional errors. A transducer 31 provides an electric signal proportional to the load. The electrode (68), Fig. 6 (not shown), is mounted on a block (69) through which pass rods (70), (71). The latter are moved by cables attached to plates (72) and wound round pulleys attached to servomotors. The graph board is made of dielectric material and the curve has inner and outer conducting areas which when contacted by the electrode operate warning lights at 75% and 85 % of the overturning load. Fig. 9 (not shown) illustrates a control circuit for the electrode. Push-buttons are provided for feeding in test voltages. The graph board may be constructed of conducting material and the graph may be non-conducting. Load cell 30 and the transducer 31 may be replaced by a piezoelectric transducer. The warning lights may be replaced by buzzers, sirens or a crane brake.

Title: Improvements in or relating to balanced rotors
IPC: G01C25/00
Filed: 1943-10-19
Abstract: 581,991. Testing balance of rotors. SMITH & SONS (ENGLAND), Ltd., S., MEREDITH, F. W., MOSS, E. B., and WHATLEY, H. E. Oct. 19, 1943, No. 17206. [Class 106 (ii)] A method of balancing a rotor such as,employed in gyroscope apparatus, includes the step of balancing it in a plane transverse to the axis of rotation by adjusting the mass of the rotor at an arbitrary point in that plane, so that when rotated the rotor is in balance about a diametric axis of the rotor not passing through said point and the further step of adjusting the mass at any point on the said diametric axis until during'further rotation the rotor is in balance about a second diametric axis at right angles to the first axis. Apparatus for carrying out the method is shown in Figs. 1 and 2, wherein the rotor 1 is mounted in a frame 2, which may be part of the gyro assembly, the frame being clamped in plates 3 to which are attached leaf springs 4 that are rigidly supported ina heavy base 5 slung on springs 6. A gramophone pick-up 7 is connected to the vibrating part of the system by a connecting piece 9. An air jet 8 on a swivel mounting is employed to drive the rotor 1. The rotor is arranged with its lower surface in the axis 11 about which the frame vibrates. ' In operation, two pairs of index marks 12, 13 are made on. the upper surface and a piece of putty 51 is placed on one of the marks and the rotor run up by the air jet to above resonance and cut off. The pick-up 7 acts on an indicator circuit and the maximum reading is noted. The putty is then put on the opposite mark and the operation is repeated and another reading taken. If the readings differ, a hole is drilled on the mark for which the greater reading was observed and the hole is progressively increased until the readings are the same value. The two marks at right angles are then treated in the same way and a hole drilled to obtain balance about the second axis. The rotor is then turned round and the other surface is treated in a similar manner. The Specification describes electric circuit arrangements for amplifying the impulses generated by the pick-up device 7 and for controlling the speed of the rotor by means of a microphone responsive to rotor noises.

Title: Process for the production of a protective or controlled furnace atmosphere
IPC: C23C8/32
Filed: 1951-07-20
Abstract: <PICT:0720371/III/1> A protective furnace atmosphere for heat treatment or hard soldering of parts requiring a reducing atmosphere is obtained by vaporizing and cracking methyl alcohol and converting at least part of the carbon monoxide formed by steam into hydrogen and carbon dioxide.  A mixture of methyl alcohol and water from a tank 8 is fed to a reaction chamber 5 through a vaporizing tube 31 surrounding an electric heating element 6 and is converted in an upper zone in contact with a cracking catalyst to hydrogen and carbon monoxide which, with the steam generated, is converted in a lower zone containing a catalyst 12 to carbon dioxide and hydrogen. Moisture is condensed in a tube 33 surrounded by a scrubber-cooler 35 over the wetted packing of which the cracked gases pass to a storage container 45, carbon dioxide being dissolved and removed with the wash water.  A valve 42 in the outlet pipe enables a pressure of at least 3 and preferably over 10 atmospheres to be created by the vaporization.  In a modification, the liquid is supplied by a pump responsive to changes in pressure in the outlet pipe and the vaporizer is heated by a burner fed by the cracked gas.  A mixture suitable for nitriding may be obtained by using an ammonia-methyl alcohol solution and for carburizing or dry cyaniding a liquid rich in carbon, e.g. benzol, is added, or methyl alcohol vapour to which ammonia may be added is mixed with the cracked gas.

Patent GB-255115-A (GB)
IPC: B64C17/00
Filed: 1926-07-13
Abstract: 255,115. Mutton, R. E. July 13, 1925, [Convention date]. Steering and balancing.-Lateral and longitudinal tilting is corrected automatically by a pendulum which controls the ailerons and elevators through pneumatic servo-motors of the follow-up type which bring into play a correcting effect proportional at each moment to the angle of tilt. The pendulum also acts directly on the control planes when the tilt exceeds a small angle, and in this way assists in preventing tilting when the air-supply of the servo-motors is cut off. The servo-motor mechanism can also be operated by the pilot's joy-stick and then acts as a power relay. During a turning movement centrifugal force displaces the pendulum to bank the machine to an appropriate angle. The pendulum J is gimbal-mounted on the stem G of a four-armed member D, which is ball-suspended from a fixing plate A and is connected by links E to a similar member F linked to the joy-stick L. The pendulum carries a spider of which each arm, such as 4, passes loosely through the corresponding arm of the member D, as shown in Fig. 2, and the ends of the two concentric arms are ball-connected to a valve-rod 8 and to a tube 12 of a servo-motor, of which the cylinder 16 is pivoted to the machine at 40. If for example the machine tilts laterallly so as to raise the arm D relatively to the arm 4, the valve 8<1> seats itself on a sleeve 21 which it depresses so as to open a poppet-valve 50, which admits compressed air from the bottom to the top of the cylinder. The piston and the tube 12 are thus depressed until the arm D has been restored to its normal relation to the arm 4, whereupon the valve 50 shuts off the upper part of the cylinder from the compressed air and the valve 8' opens it to the atmosphere. The movement of the member D is communicated to the joy-stick and effects the appropriate control. Lateral tilting in the opposite direction would have no effect on the servo-motor 16 but would bring into play the servo-motor 15. Longitudinal tilting is taken care of by a similar pair of servo-motors in a plane at right angles. The general arrangement is shown in Fig. 4. A valve U enables the pilot to shut off the air supply to the servo-motors. To enable manual operation to be effected the control lever L is slightly loose in its socket and is connected by a ball joint to a member 45 which is connected to the arm 4 of the pendulum spider.
