Title: Method of and apparatus for erecting a mast
IPC: E04H12/34
Filed: 1974-02-08
Abstract: 1465841 Erecting masts J CLOUP 8 Feb 1974 [22 Feb 1973] 05892/74 Heading B8B A mast 17 is erected by means comprising an erection device 18 and guy ropes 20a, 20b attached respectively to the upper part of the mast 17 and pass about pulleys 21a, 21b respectively which are fixed to the ground. The device 18 comprises three friction rollers 26 (only one shown) spaced at 120 degree intervals and which engage the mast, each roller 26 being driven by a respective hydraulic motor 28 on whose output shaft 29 is keyed a sun gear-wheel 30 in mesh with planet gearwheels 31 mounted to rotate on a support 32 fixed to an output shaft 33, the planet gearwheels 31 also meshing with a sprocket wheel 34 fixed to the associated friction roller 26. The shaft 33 has a cog-wheel 35 keyed thereto which is connected via a chain 37 to a cogwheel 36 keyed to a rotatable shaft 38 on which a pulley 42 is keyed, one of the guy ropes being wound on the pulley 42. In any position of equilibrium with each hydraulic motor 28 locked, and the mast 17 vertically stationary, the weight of the mast and the resolved downward force exerted thereon by the guys is balanced by the friction effect of the rollers 26, the latter being prevented from turning by reason of the tension in each guy exerting a turning movement on the associated pulley 42 and thus via the chain 37 on the roller 26. To adjust the height of the mast, the motors 28 are actuated, and by reason of the differential gearing and the fact that the tension in each guy exerts a couple on the associated pulley 42 the motors 28 rotate the pulleys 26 to cause vertical movement of the mast. If the mast 17 should lean to one side it contacts a roller (46), one such roller being mounted above each roller (26), Fig. 5 (not shown), the roller (26) then pivoting about a shaft (49) to move a rod (52) coupled therewith, the rod having a bracket (61) fixed thereto in engagement with a roller (60) on a lever (58) which controls the direction of rotation of the associated motor 28, Fig. 6 (not shown), actuation of the lever (58) causing the associated motor to increase or decrease the length of the corresponding guy to bring the mast back to a vertical orientation. In the embodiment of Fig. 1 (not shown) the bottom of the mast (1) is located in a pit (2), and guys (5, 5a) extend from the upper part of the mast about pulleys (8, 9) and (8a, 9a) respectively which are fixed to the ground and about a pulley (11) mounted on a piston-rod (12), to respective fixing points (7a, 7). The piston-rod (12) is fixed to a piston (13) located in a barrel (14) which is firmly fixed to the mast (1). Injection of fluid below the piston (13) causes raising of the mast.

Title: An improvement in or relating to brakes for rotating members having self-regulated substantially constant braking torque
Inventor: TUPLIN WILLIAM ALFRED
IPC: F16D65/22
Filed: 1950-03-09
Abstract: 688,042. Self-regulating brakes. BROWN & SONS (HUDDERSFIELD), Ltd., D. June 11, 1951 [March 9, 1950], No. 5909/50. Class 103 (i). The torque reaction in a brake is transmitted by an arm movable angularly in either direction against spring action, movement of the arm being arranged to reduce the brake application force so that the arm finally rests in a position which corresponds to a substantially constant brake retarding torque dependent on the final compression of the spring. In the arrangement shown, shoes band b<SP>1</SP> are applied to the brake drum by fluid pressure from a pump e, under control of a throttle valve f, acting in the cylinder a. The projecting arm j is carried on the brake anchor plate on which the shoes are mounted and under the action of the braking torque moves one way or the other to compress spring m. A projection j<SP>1</SP> carried by the arm j thus engages stops i or i<SP>1</SP> on rod h to unseat ballvalve d<SP>1</SP> so that the fluid pressure acting in cylinder a is reduced. The arm j thus attains an equilibrium position at some compression of the spring m corresponding to a substantially constant retarding torque.

Title: Improvements in or relating to fluid pressure operated means for indicating the quantity and specific gravity of the liquid contents of tanks
IPC: G01F23/18
Filed: 1925-03-04
Abstract: 256,289. Martin, H. March 4, 1925. Indicators, electric.-The level of oil in a tank in which it is displaced by water is indicated at a distance by means controlled by variations in electrical resistance produced by the movement of two columns of liquid, and the specific gravity of the oil is also measured and the level readings corrected therefor. The apparatus is in two main portions, a transmitter A mainly constructed as described in Specification 231,595, and indicator B, preferably of the ratio coil type similar to those described in Specifications 164,828 and 219,716, [both in Class 40 (i), Electric signalling systems &c.]. Part of the variable resistance coil 13 is removed to the indicator B at 15, and part of the external fixed resistance 45 is placed adjacent to the resistance 15 at 17. The unit C is employed to compensate for specific gravity variations. The resistances 15, 16, are simultaneously controlled by a hand-operated arm 17 carrying a pointer 18 moving over a scale of specific gravities. The resistances 15, 16 are such that with both fully in circuit, a full-scale reading of B is obtained when the whole of the resistance 13 is short-circuited by immersion in the mercury, and when both are cut out by the arm 17, a full-scale reading of B is obtained with half the resistance 13 short-circuited. To obtain the specific gravity of the oil in the tank, a pair of insulated contacts 25 are inserted in the tank at the " ¥ full " position, and are connected through a switch and battery to a galvanometer 29, a corresponding mark being made at the "¥ full." position of the indicator B. When the tank is being filled, the contacts 25 are opened when reached by the oil, and the arm 17 is then adjusted until the scale reading on the indicator is ¥ " full." The reading on the scale 19 then indicates the specific gravity, and accurate readings of level are obtained on the indicator B as long as the specific gravity remains constant. A change in specific gravity necessitates a re-setting of the arm 17. If applied to an ordinary storage tank without water displacement, the contacts 25 would be placed at the top of the tank, and would indicate " tank full."

Title: Process for treating edible nuts
IPC: A23L25/00
Filed: 1933-02-27
Abstract: Shelled nuts are passed through a heated aqueous solution of an alkaline reagent for a period of time insufficient to cause any substantial chemical reaction between the nut meat or the oils therein and the reagent.  In a specific example the solution contains six ounces of sodium carbonate to a gallon of water and the nuts are immersed in this solution (at its boiling point) for from one to seven minutes; the treated nuts are subjected to a stream of water under pressure and preferably at a temperature of 160-200 DEG  F. until the skins and associated saponified matters are removed; any alkalies absorbed are neutralized by immersing the kernels in a weak, warm solution of acetic, citric or other acid after which the kernels are washed in clear water and dried by a current of hot air preferably under reduced pressure or steamed. One ounce of glycerine may be added to the sodium carbonate solution the time of immersion then being less.  The shelled nuts may be preliminarily impregnated with a liquid fatty material.
