Abstract: 1,137,005. Friction clutches; internal shoedrum brakes; fluid-pressure brakes. HORTON MFG. CO. Inc. 28 March, 1966 [28 April, 1965], No. 13670/66. Headings F2C, F2E and F2F. In a friction brake (shown) or clutch (Figs. 7, 8, not shown), particularly for unwinding large rolls of material in paper or textile mills, comprising a brake, stationary, or clutch, driving, drum 80, (81) and a brakable or clutch driven friction shoe-carrying member 14 keyed on a rotatable shaft 12, each of levers 42 pivoted at 34 on spider arms 18 of the member 14 terminates on one side of the pivot 34 in a weight 54, has pivoted thereto at 60, part-way along its length on the other side of the pivot 34, a friction-lined shoe 66, and is pivotally connected at 64, at its extremity beyond the pivot 60, to the rod 120 of a diaphragm servomotor 84, the pneumatic energization of which frictionally engages the corresponding shoe with the internal surface of the drum, and to produce equal braking or clutching torque in either direction of relative rotation for an equal applied engaging force, the construction is such that in a plane normal to the brake or clutch rotational axis a line through said rotational axis and pivot 34 is substantially normal to a line through the pivots 34 and 60 when the corresponding shoe engages the drum. The servomotors 84 (Fig. 3, not shown) are pivoted to the member 14, are spring returned, and their diaphragms are adjustably threadedly connected to the rods 120. All the servomotors 84 are simultaneously energized through a supply line 104, a rotary union 102, a central bore (100) and radial bores (98) in the shaft 12, and lines 96, 106 and 112, 116. The supply line 104 is equipped with a quick on-off valve, pressure regulator and visual air gauge not shown. The air pressure may be controlled separately by either the quick on-off valve or, for fine adjustment, by a screw type regulator valve. In operation of the brake shown, for a given servomotor pressure, the braking torque decreases as the speed of the shaft 12 increases since the centrifugal force created by the weights opposes the frictional engaging force applied by the servomotors, this arrangement providing uniform tension on the material of a roll which increases in speed as it decreases in diameter during material unwinding. In the clutch of Figs. 7, 8 (not shown), the drum has peripheral V-grooves accepting driving V-belts.

Title: Improvements in Gas and Vapour Pumps for Internal-combustion Engines of the Constant-pressure Cycle.
Inventor: BROOKE HOLMAN LINNEL
IPC: F02M21/00
Filed: 1918-03-23
Abstract: 116,988. Brooke, H. L. March 23, 1918. Addition to 112,185. Regulating; valves; valve-gear.-The parent Specification describes a cam-actuated pump in which liquid fuel is vaporized and delivered into the engine cylinder during the beginning of the working stroke through a cam-actuated valve. According to this invention, the pump is driven by a crank or eccentric, and the compressed charge is delivered into a pocket C whence it is admitted through a port D into the cylinder. The port F leading to the pocket is controlled by an oscillating ported sleeve B which carries on its end cam surfaces J which engage inclined surfaces L on the end of the valve A. The valve is adjusted angularly by a lever K to alter the period of contact of the surfaces J, L and the degree of opening of the valve. The sleeve B may reciprocate instead of oscillate, or it may be dispensed with, and the valve A, Fig. 5, may be modified to oscillate and control both the inlet F to and outlet D from the pocket. The pocket may be fitted with a spring-pressed plunger E' to adapt its capacity automatically to the weight of gas admitted. The clearance in the first stage compressor may be adjusted by screwing the rod W of its piston V on to the rod X of the high pressure piston and securing them with a lock-nut. A further modification of the pump for compressing a mixture of combustible gas and products of combustion consists in making the pistons hollow to transfer the charge from beneath the larger part V to the space above the upper part, the piston-rod X forming a valve and being held against the smaller piston by a spring. The gas and combustion products are admitted to the pump through separate ports in an adjustable cylindrical valve.

Abstract: 898,359. Aircraft. AVRO AIRCRAFT Ltd. May 10, 1955 [May 11, 1954], No. 13789/54. Class 4. [Also in Group XXVI] A stream of gases is discharged peripherally from a lentiform aircraft and this stream is divided into two streams having opposite components of thrust normal to the medial plane of the aircraft, the magnitudes of the two streams being varied to control the aircraft. The outlet from a radialflow gas turbine is ejected from a peripheral outlet 47 as described in Specification 898,358 but is normally divided by an annulus 50, some flowing outboardly and upwardly, the rest flowing outboardly and downwardly. This annulus 50 is movable by hydraulic jacks 53, 59, 64, 70, from a take-off position in which the outlet gas is prevented from flowing upwardly, to a flying position in which the annulus is eccentric with respect to the craft, the outlet 47 being blocked at the front and the gaseous streams elsewhere flowing over and under the annulus. With the annulus 50 in the flying position the craft is controlled by the actuation in pairs of jacks 56, 60 or 67, 71, by a handle 80 to vary the vertical component of thrust at one point or at two opposed points on the periphery 90 degrees from the sector it is desired to raise or depress, using the gyroscopic effect. Steering is effected by controlling the outlet through louvres 85. Air intakes are provided at 35 and corresponding apertures in the underside and also at 33, sliding doors being provided to close all these openings. As in the prior Specification 898,358 the aircraft utilizes the Coanda effect. Specification 892,401 also is referred to.

Title: Improvements in and relating to electric heaters for heating liquids
IPC: F24H1/22
Filed: 1920-05-21
Abstract: 172,036. Marks, E. C. R., (Langguth & Haar). May 21, 1920. Heating by electricity; electric radiators.-An electric heater for liquids in which the heating- element may be entirely removed without affecting the liquid-containing part of the heater, comprises a tank 9 of round, square, radiator, or other shape having a base with a tapered recess in which wedge-shaped heating-element is inserted. The recess is formed in a metal body 13 which is formed with a flange 17 adapted to be screwed to the base of the tank. The resistance 10 is tightly pressed between two tapered metallic plates 11, 12 and is held in the tapered recess by screws 15 and a closing-plate 16. The current through the resistance is controlled by a switch 18 operated by the dilation and contraction of a liquid contained in the space between two tubes the inner tube being flexible and carrying a rod 20 pivoted to a lever 22. The lever 22 is pivoted on a standard 31 rising from the base plate 30 of the switch and is provided at each side with an abutment through which the screwed stem of a hook passes. Springs 24 connect these hooks with hooks on a U-shaped switch member 23 pivoted in brackets 32 and carying a bridge piece 33. Expansion of the liquid raises the rod 20 moving the lever 22 until the axes of the springs pass the pivot of the switch member 23. The n,ember 23 then lifts and the circuit remains open until the rod 20 falls sufficiently to bring the axes of the springs below the pivot of the switch member again. By adjusting the tension of the springs the temperature at which the switch is operated may be varied. The inlet 26 for the water or other liquid to be heated is so situated that the flow is directed first on to the thermostat and then on to the heating-element.

Title: Improvements relating to the manufacture of articles from paper ribbons
Filed: 1933-05-16
Abstract: 414,484. Making non-cylindrical vessels &c. of paper &c. MOLLER, A. I. B., Stabekk, near Oslo, Norway. May 16, 1933, No. 14179. [Classes 18 and 66.] In a method of manufacturing non- cylindrical articles such as jars, lamp stands, bowls or vases of circular, oval or other cross section of paper, fabric, wood shavings, or the material known under the Registered Trade Mark " Cellophane " having its convolutions overlapping in telescopic fashion as shown in Fig. 1, the ribbon is wound in a machine on to the surface of a mandrel having the shape of the interior of the article to be produced, the ribbon being displaced with respect to the mandrel during winding at such a rate that the interior of the wound article conforms to the shape of the mandrel as it is wound, the mandrel being subsequently removed. The ribbon may be coated on one or both sides before winding with a binding agent, e.g. diluted fish glue, or may be impregnated during or after winding with oil to render it transparent. The wound articles may be suitably embossed, and the finished article may be reinforced by winding on further turns of ribbon which may be coloured if desired at certain points. A suitable base member 8, electric connecting supplies, lamp sockets or similar members may be incorporated in the wound articles. A suitable mandrel is formed by cutting segments from a spun or drawn copper vessel to leave a number of strips 16 which are divided at two points to form portions a, b, c which are hinged together, the hinges having stops so that they only open to the desired extent. The mandrel is carried in a shaft 19 having an appropriate polygonal enlargement 20 at one end and being reduced at the other to receive a disc 21 having a groove 22 to receive the cranked upper ends of the portion a of the strips 16. The shaft 19 is arranged in coaxial engagement with the longitudinally movable shaft 24 which is splined to the shaft 25. This shaft is driven by a pulley 26, and driven by suitable gearing or sliding table 27. A pin 28 carried in a collarlike holder 29 on the shaft 24 projects into a cam groove 30 in the table 27. The holder 29 is adjustably fixed on the shaft 24 by two collars 31 and is prevented from rotating by a fixed rod passing through it. The ribbon passes from a roller over suitable guides and between two rollers, the lower of which is supplied with adhesive by a third roller rotating in a bath of adhesive, and is clamped to the mandrel between strips provided for that purpose, or is wedged in an aperture in the shaft. Winding is always started at a point of minimum radius such as 4 or 5, Fig. 1, and continued to one of maximum radius such as 6 and then the machine is stopped and winding restarted at another point of minimum radius. Points of maximum radius are finally reinforced by moving the mandrel to and fro several times while winding at that point. Specifications 118,109, [Class 66], and 362,767 are referred to.
