Title: Improvements in or relating to Motor Power Plant.
IPC: F22D1/32
Filed: 1918-10-29
Abstract: 120,889. British Westinghouse Electric & Manufacturing Co., (Assignees of Ehrhart, R. N.). Nov. 21, 1917, [Convention date] . Regulating.-In a steam power system comprising a main steam-engine and an auxiliary steamengine, the exhaust from which is used for heating the feed water, the steam supply to the auxiliary engine is automatically varied with the amount of the steam consumed by the main engine. A main turbine 5 discharges into a condenser 8, which has its condensate pump 14 and air pump 15 driven by an electromotor 17 and an auxiliary turbine 18, the exhaust from which is delivered by a port 21 to the feed-water heater. The turbine 18, which is connected to the motor 17 by reduction gearing 19, receives steam from the main turbine through a pipe 20, the supply to both turbines being controlled by the same valve 10, and the proportion of steam delivered to the auxiliary turbine and thereby rendered available for feed-heating purposes remains constant ; the electromotor 17 carrying a greater or less proportion of the load on the auxiliaries in accordance with the amount of steam delivered to the auxiliary turbine 18. Under certain cond.itions, the motor 17 operates as a generator. Where the main turbine is provided with overload inlets at intermediate stages, the conduit 20 is connected by a pipe 20<a> to the working passage of the main turbine at or below such stages. In a modification, high-pressure steam is supplied to the auxiliary turbine through a. valve controlled by the pressure at a point in the main turbine where such pressure is a measure of the total amount of steam passing through the main turbine.

Title: Improvements in or relating to fire escapes
IPC: E06C5/16
Filed: 1925-07-09
Abstract: 247,458. Magirus Akt.-Ges., C. D., and Hetzelberger, F. July 9, 1925. Portable wheeled escapes.-A fire-escape of the kind in which the raising and extending gears are automatically controlled to prevent tilting over of the escape, is provided with means for stopping the gears automatically if the escape encounters an obstruction. The turntable 2, which runs on balls 4 and has counter-rollers 5, is provided with sliding abutments 9, 10 which support the escape-supporting frame 1 and are themselves upheld by two-armed levers 11, 12 pivoted at 13, 14. The inner ends of the levers 11, 12 have a pin and slot connection with a rod 18 normally held downwardly by a spring 16. When the escape begins to tilt, for example on striking an obstruction during raising, one abutment 9 or 10 will be depressed, raising the inner end of the corresponding two-armed lever, and causing the upper end of the rod 18 to act on levers 19, 20 of control members 21, 22 of known form to shut off the supply of pressure fluid from the raising and extending gears. In a modification, the two-armed levers are pivoted to a ring spring-mounted below the turntable. In another modification, feeler-levers pivoted below the turn-table are connected to an oscillating lever to the centre of which the rod 18 is connected.

Title: Improvements to ground anchors
IPC: E02D5/80
Filed: 1965-04-28
Abstract: 1,068,357. Ground anchors. SCHWABISCHE HUTTENWERKE G.m.b.H. April 28; 1965 [April 30, 1964], No. 17793/65. Heading E1B. [Also in Division F2] A ground anchor which can be expanded below ground to secure a cable attached to a hole 15 therein comprises a sleeve 3 having longitudinal slits 5 and a solid tip 2 screwthreadedly engageable by a detachable driving rod 4 having a striking head 7. After driving in the anchor a nut 10 on the rod 4 is actuated to contract the sleeve 3 and thereby buckle its slit portion 6 outwardly to project into the ground. The rod 4 is then detached leaving only the sleeve 3 in the ground. The sleeve may subsequently be remmoved from the ground by driving in the rod 4 to straighten the buckled portion. Alternatively the anchor sleeve may be fixed by pouring concrete into the buckled portion. In a modification the actuating nut 10 is replaced by a pneumatic or hydraulic cylinder.

Title: Improvements in or relating to paper folding machines
IPC: B65H45/12
Filed: 1931-06-19
Abstract: 375,542. Folding paper. SPIESS, G., 78, Zschochersche Strasse, Leipsic, Germany. June 19, 1931, No. 17856. Convention date, July 29, 1930. [Class 100 (ii).] In a buckling-folder apparatus for paper sheets, the folding-rollers 7, 8 are arranged with their axes parallel to the direction of feed, and the sheets after abutting against the front stops 5 of the buckling-plate 6 are moved laterally against a side-gauge 9 before being buckled into the bite of the rollers 7, 8. The roller 8 is constructed as a suction roller so as to cause the lateral movement of the sheets. A suitably shaped plate 10 situated above the rollers 7, 8 facilitates the buckling of the sheets, and is rounded off at one end so as not to impede the feed of the sheets. A tubular sleeve mav be built into the end of the roller 8 to shut off the end suction holes if short sheets are being dealt with. According to the Specification as open to inspection under Sect. 91 (3) (a) the rollers 7, 8 may be relieved of the work of forming the fold by arranging a pair of suction rollers above them which act until the fold is gripped by the rollers 7, 8. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to friction testing apparatus
IPC: G01N19/02
Filed: 1936-09-18
Abstract: 466,663. Friction-testing apparatus. SHAW, F. W., and SHAW, H. Sept. 18, 1936, No. 17975/35. [Class 106 (ii)] In apparatus of the type in which the coefficient of friction is computed from the frictional force and the load producing it, both of these forces are measured by a diaphragm D displacing liquid into a pressure gauge P. The gauge may be connected directly and not act through a capillary tube as shown. The bearing b to be tested forms a sleeve on a rotatable shaft a and is loaded by a lever E having a fulcrum F and connected to the bearing by a linkage 1, 2, 3. The end of the lever E bears against the diaphragm D. A cam ring R rotated by a handle H serves to apply the load, part of which may be furnished by a weight W. The force of friction is measured by a link and lever system L, E<1>, the lever E<1> rocking about a fulcrum F<1> and acting on a diaphragm D<1>. Part of the force may be balanced by a weight W<1>. The pressure gauges P may be of the self-recording type.

Title: Improvements in and relating to engine governors
Filed: 1924-07-28
Abstract: 242,329. Edenborough, H., and Driver, D. W. July 28, 1924. Inertia governors; fluid relays. - In a marine governor of the kind in which a ball 3 rolls on a track 2 pivoted out of its centre the fluid pressure on the pilot valve 16 of a relay is neutralized by a spring 17 which may have an adjusting nut 18. The ball assists the spring to close the valve, but in a modification in which a vacuum is used in the relay the ball opens the valve against the action of the spring which normally closes it against atmospheric pressure. The inclination of the track is adjusted by a screw adjustment 5 of the pivot 4. Specifications 287/94, 29078/10, 12355/13, and 120,767, are referred to.

Abstract: 721,396. Weighing apparatus. FLAVEL, & CO., Ltd., S. Oct. 19, 1953, [July 17, 1952], No. 18126/52. Class 143. A gauge for indicating the weight of fluid contents of a container comprises a part adapted to engage the lower edge of the container and to move against a spring relatively to a second part co-extensive with the first part, the relative position of the two parts indicating the weight. The container 6, Fig. 3, is supported on flange 8 and a platform 11 pivoted at 12, so that its weight depresses casing 1 against the action of spring 19 on rod 2. Rod 2 carries a fixed cap 21, Fig. 4, engaging a coarsely 'threaded rod 22, so that as the rod 2 moves relatively to casing 1, the rod 22 rotates to rotate pointer 28 on a scale 26, which can be adjusted and locked by screw 27. In a modification, Figs. 6 and 7, the rod 2 is pivoted at 39 to a sector 31 which rotates about 32 and carries a scale on its edge 33, so that movement of rod 2 relatively to the casing 1 causes rotation of the scale; an index pointer 35 is manually adjustable.

In the construction shown the brake members are in the form of interleaved brake discs of a multidisc brake. The disc brake is mounted in a housing 4 connected to the part 2 of the stock and one set of discs of the brake are slidably connected to a hub 17 fixed in the housing. The other set of discs of the brake are driven by a rack and pinion arrangement through a oneway roller clutch 22, 28, 31, rack teeth 30 being formed on one 8 of a pair of guide rods 7, 8 attached to the part 9 of the stock.
