Title: Booster pressure control for liquid systems
IPC: F16D25/12
Filed: 1962-08-24
Abstract: 995,289. Centrifugal pumps. TWIN DISC CLUTCH CO. Aug. 24, 1962 [May 15, 1962], No. 32700/62. Heading F1C. [Also in Divisions F2 and G3] A constant speed electric motor 10 drives a shaft 11 with a hub 12 embodying an annular cylinder 14 housing an annular piston 15, rightward movement of which engages a clutch 16; alternate clutch plates are attached to the hub 11 and a spider 18 that is connected to a centrifugal pump 19, the outlet 22 of which leads to a distribution system. The, motor also drives another pump 23 which draws oil from a sump 24 and delivers it to a valve chamber 27 incorporating a pressure-regulating valve 32 and a modulating valve 33 comprising a piston closure 38 having a spindle 39 partially enclosed in a diaphragm 40, the rear of which is open to the centrifugal outlet 22. When the pump 23 is driven the valve 32 is unseated and enables the fluid in chamber 26 to flow through a passage 54 and hub channels 55, 56, 57 so cooling the clutch plates. With the valve 33 in the position shown fluid from chamber 26 also flows to the cylinder 14 via a passage 45, an annular groove 46 around the bore for the valve 33, a passage 47, and hub channels 49, 50, 51. Rising pressure in the outlet 22 causes leftward motion of the closure 38 which results in uncovering of groove 46 whereby fluid from passage 45 flows into passage 54 so that the pressure on piston 14 is relieved and the speed of the centrifugal pump is reduced.

Title: Improvements relating to the production of iron sponge
IPC: C21B13/00
Filed: 1927-12-06
Abstract: 296,235. Sieurin, S. E. Dec. 6, 1927. Drawings to Specification. Extracting.-In the method of producing iron sponge by reducing pulverized briquetted ore embedded in a solid reducing agent intimately mixed with lime or magnesia at a temperature below the melting point of the metal and in the absence of air or other gas, an excess of the reducing agent, preferably carbon, is employed in the charge such that free carbon is present in the ash at the end of the reducing process. At the same time the cooling of the product is accelerated to prevent any sulphur present recombining with the reduced metal sponge. If only a little free carbon is present in the ash the cooling should be rapid, and it may be slower if a large percentage of carbon is present. As an example, if the excess of carbon is 20 per cent of the weight of the ash, the latter should be cooled to 850‹ C. in 12 hours and to 500‹ C. in 36 hours.

Title: Improved means for filling containers with a pre-determined weight of liquid
IPC: B65B3/28
Filed: 1958-10-20
Abstract: 873,360. Dispensing liquids by weight. EARNSHAW, J. W. Sept. 1, 1959 [Oct. 20, 1958], No. 33366/58. Class 143 A container supported on the platform of a weighing apparatus is automatically filled with a predetermined weight of liquid through a pourer 11 by means of a feed valve 10 having a pivoted actuating lever 9 which is held in valveopen position by a suction head 7, 8 connected to a vacuum conduit 3, an element 14 on the weighing apparatus being movable in response to the required weight of liquid in the container to open the conduit 3 to atmosphere thereby breaking the suction and permitting the lever 9 and valve 10 to fall to valve-closed position. As shown the element 14 is a shim on the end of a weigh beam 12 movable to uncover a port 15 in the conduit 3. Where the weighing apparatus comprises a pointer moving around a dial, an axially flanged disc on the pointer spindle may have a gap in its flange to register with a port in the vacuum conduit when the required weight is registered by the pointer. In this case the port is provided in a radial arm which is angularly adjustable to the required pre-set weight position.
Patent GB-889668-A (GB)
Title: Improvements relating to the grading of articles, particularly eggs, according to weight
Inventor: LAWSON CLIFFORD WILLIAM
IPC: B07C5/24
Filed: 1958-10-20
Abstract: 889,668. Sorting by weighing. BRECKNELL, DOLMAN & ROGERS Ltd. Oct. 19, 1959 [Oct. 20, 1958], No. 33372/58. Addition to 875,797. Class 143. The weight grading machine of the parent Specification is modified by the replacement of the six solenoids controlling the action of each of the distributer units operated by the memory device by a single solenoid. As in the parent Specification, there are four consecutively traversed egg-weighing stations each controlling one of the switches S1 to S4 (Fig. 27) by which the computor C is conditioned to operate the appropriate one of the distributer units N1 to N4 according to the weight of the egg being graded. Each distributer unit incorporates the single solenoid 301 which is operated by the closure of one of the switches E1 to E4 of the computor after a delay from the making of the appropriate one of the switches S1 to S4 equal to the time taken for an egg to be conveyed, as in the parent Specification from one of the switches S1 to S4 to the delivery zone of the graded egg. The energization of a solenoid 301 causes the rocking of lever 336 (Fig. 22) to turn shaft 338 and with it lever 337 to remove a pin 339 from a tooth of the six-tooth ratchet wheel 340. The wheel 340 is frictionally coupled to a constantly rotated shaft (not shown) and is thus rotated through 60 degrees for each actuation of the solenoid 301. The shaft 332,-which is keyed to the ratchet wheel 340, also carries a set of six levers 342 (Fig. 23) each of which cooperates with one of a series of levers 348 all pivoted on a common shaft 349 and each carrying a pin 302, so that each 60 degrees advance of ratchet wheel 340 causes the withdrawal of one of the pins 302 from the single tooth of the corresponding one of a series of six ratchet wheels 303 frictionally coupled to a common continuously rotated shaft 331. The thus-permitted single revolution of the appropriate wheel 303 causes a cam 308 carried thereby to engage a roller 309 carried by a lever 310 and cause the latter's free end 311 to move a pin 312 to actuate a trip lever 157 and thereby cause the egg to drop into the appropriate compartment of a Keyes tray as described in the parent Specifica- .tion. One of the six ratchet wheels 303 carries an addition cam 313 (Fig. 25, not shown) which, when rotated by each sixth operation of the solenoid 301, operates a solenoid controlling the clutch of the appropriate conveyer of the Keyes trays to position a new tray in the manner described in the parent Specification.

Title: Improvements relating to controlling arrangements for aeroplanes
IPC: B64C3/54
Filed: 1934-11-22
Abstract: 439,592. Controlling aircraft. MESSERSCHMITT, W., 118A, Haunstetterstrasse, Augsburg, Germany. Nov. 22, 1934, Nos. 33578, 33579, and 33580. Convention dates, Feb. 24, March 14, and March 24. [Class 4] Apparatus, for the lateral control of aeroplanes, comprises spoiler vanes adapted to be projected from the upper surface of the wings by the operation of a manual control device which operates so that a uniform increase in the displacement of the control device through substantially its full range of movement is arranged to effect a continuously decreasing increase in the effective extent of the projection of the spoiler vanes whereby the rolling moment of the aeroplane is continuously increased during the displacement of the control device. The spoiler vane may be divided into two or more unequal sections in the direction of the wing span and the control device constructed so that in its initial movement it projects the smaller vane at a rapid rate and subsequently raises the larger vane or vanes at a reduced rate. In Fig. 7 (not shown), the spoiler vane is projected by a rotatable bell-crank lever positioned so that rapid regular movement of the vane is attained during the initial movement of the bell-crank lever. In an alternative construction Fig. 8 (not shown), a roller on the arm of a bell-crank lever engages a cam-shaped surface on the underside of the spoiler vane. As shown in Figs. 9, 10 the initial rapid movement may be effected by a shaped cam k and where the spoiler vane is divided into two unequal portions, the smaller part is projected by a cam k as shown in Fig. 9, whilst the slower movement of the larger vane is effected by a differently-shaped cam k as shown in Fig. 10. In a modification Figs. 11, 12 the vane b is torsionally twisted, about an edge in the wing by a set of cams p<1> .. p<4> arranged along a rotatable shaft o and arranged to come into action successively with a decreasing rate of projection of the vane. In a further modified construction, Fig. 13, a vane b is projected from a slit in the wing d by a slider s formed with arms z<1>, z<2> which engage lugs u<2>, u<1> carried by the vane. The width of the vane may be varied along its length so that the area projected during the initial movement of the control member is additionally increased. The spoiler vanes may be held in their normal positions by springs arranged so that the spoiler vanes are automatically projected from their normal position when the pressure on the wing in the locality of the vanes is abnormally low, e.g. under high lift conditions.

As described, a disc 7 on the element 1 limits the pivotal movement. The studs 22 are each slidably mounted in slots formed in upper and lower plates 13, 17 of the support structure, the two plates being relatively rotatable and the slots being aligned at an angle to each other. The support of the apparatus is levelled after the studs 22 have been moved to accommodate the wheel to be checked. The wheel is then mounted on the support and weights added to its periphery until the spirit level 11 again shows that the support lies in a horizontal plane, the position of the weights then being marked. After removal of the wheel, the weights may be secured to the wheel at the marked positions.
