Filed: 1971-04-08
Abstract: 1287076 Screening device COSHAM ENG & DESIGN Ltd 8 April 1971 9115/71 Heading B1D [Also in Divisions B4 and B5] A screening device which is arranged upstream of a plastics extrusion head comprises a body 10 with a through passage 12 intersected by a transverse passage 14, individual screen blocks 18 being slidable through passage 14 to position one block across passage 12, through which the plastics flows, channels 34 and 36 enabling a clean block adjacent passage 12 to be filled with plastics from the upstream end of passage 12 before ram 20 is used to force a third block 18 into passage 14 and thereby push a clogged block out of passage 12 and replace it by said clean block. Passage 14 accommodates three blocks, the centre one across passage 12, and when a fourth block is forced in the lowermost block is forced out. Channel 34 is controlled by a valve 38, 40. In Fig. 2 valve 38 is manually operated and ram 20 actuated by an operator observing an excess upstream pressure registered by means 42, but the valve and ram could be controlled automatically by a pressure switch and timer. Each block 18 comprises an array of through holes 18a and an upstream recess accommodating one or more filter gauzes.

Patent GB-617261-A (GB)
Title: Improvements in or relating to electrical repeaters
IPC: H03F1/36
Filed: 1946-03-25
Abstract: 617,261. Valve amplifying circuits. MARCONI INSTRUMENTS, Ltd., and BROCKELSBY, C. F. March 25, 1946, No. 9174. [Class 40 (vi)] In a repeater circuit, distortion is reduced by connecting across the repeater a negative feedback repeater which is in itself a distorting circuit. The auxiliary repeater circuit has such a value of non-linearity that it compensates for the distortion in the main repeater. The negative feedback repeater preferably consists of a valve or valves similar to those of the main repeater and operating under the same conditions of drive and load. -Negative feedback is applied across the auxiliary repeater so that the ratio of distortion introduced by the main repeater alone, to that introduced by the auxiliary repeater alone is equal to Á, #, where Á, and # are the amplification factors of the main repeater alone and of the negative feedback repeater alone. The Figure shows a repeater 1 in which distortion is corrected for by applying negative feedback by means of condenser 7 and resistance 8 across the valve V2 of an auxiliary repeater 4. It is assumed that valve V1 is alone responsiblo for introducing distortion into repeater 1 and valve V2 in the correcting repeater operates under similar conditions to those of V1. Distortion in a modulator or demodulator may be compensated for by including in the circuit a repeater having an auxiliary repeater in the feedback path which introduces sufficient non- linearity to compensate for the distortion in the modulator or demodulator circuit.

Title: Improvements in or relating to connecting rod assemblies for radial-cylinder internal-combustion engines or pumps
IPC: F16H21/34
Filed: 1947-04-09
Abstract: 658,957. Driving gear. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. April 9, 1947, No. 9471. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 13, 1947.] [Class 7(ii)] [Also in Group XXVI] The connecting rods Bn of a radial-cylinder engine are pivoted at An to a connecting ring Cr rotatably mounted on a crank-pin Cp, the ring being prevented from rotation about the axis of the pin by a hydraulic device comprising pistons 1, 1<SP>1</SP> pivoted at Dn to arms H rigid with the connecting rods and moving in cylinders filled with hydraulic liquid. The outer set of chambers above the pistons 1 are interconnected, and the inner set of chambers below the pistons 1<SP>1</SP> are interconnected so that as the crankpin rotates the pistons are reciprocated by the motion of the connecting rods, the total volume of liquid in each set of chambers being unaffected by the reciprocation. To vary the setting of the ring, and hence the compression ratio and timing, a plug V in a passage F, connecting the. inner and outer sets of chambers, is removed to allow liquid to flow from one set to the other on adjustment of the setting. Preferably two sets of hydraulic pistons 1, 1<SP>1</SP> and 2, 2<SP>1</SP> are provided on the connecting ring. The Specification as open to inspection under Sect. 91 comprises also an engine in which the connecting rods x are pivoted to a ring b mounted on a crank-pin m to rotate therewith, the ring being prevented from rotating about the axis of the pin by a planetry gear train P 1 , P 2 , P 3 , P 4 . The gear wheel P 1  fixed to the ring b, meshes with a planet wheel P 2  on a shaft a located in the crank-throw and carrying a second planet wheel P 3  meshing with a gear P 4  fixed to the crank case C. The angular position of P 4  may be adjusted by a worm gear V, thus adjusting the angular position of the ring b about the axis of the pin m. By this means the inclination of the connecting-rods x at top dead-centre may be adjusted to vary the compression ratio. To assist the expulsion of exhaust gases the worm gear V may be oscillated 2T with a period of - where T is the period n of the crank-shaft and n the number of cylinders, this motion oscillating the ring b so that at the end of the exhaust from any cylinder, minimum clearance is obtained whilst at the end of compression the clearance corresponds to the desired compression ratio. In place of the planetary gear, the rotation of the ring b about the axis of the pin m may be prevented by other means such as an auxiliary crank arm pivoted to the crank-case and to the ring. This subject-matter does not appear in the Specification as accepted.

In an alternative embodiment the clamping arm of the member is formed with a pivotable extension so as to be self aligning with the top surface of the insert and is particularly suitable when reversible inserts are used. The particular embodiments described are examples of parting-off tools.

In the figure illustrating a water treating apparatus embodying these features and other preferred features, which may be used for softening water by the cold lime-soda ash process, and for the clarification of waters containing suspended solids, colour and organic impurities by coagulation with alum or ferric sulphate or other coagulants, the cylindrical tank 12 contains a cylindrical partition 18 and uptake member 20 including an annular distribution chamber 26 and nozzles 28 (two shown). Untreated water is fed in through conduit 30 and is discharged upwardly through a cylindrical medial portion 32 of 20 and thence through a frusto-conical flow control portion 34. When a large amount of precipitate is formed an annular premixing zone 36 may be added to 20; a disc-like baffle 38 and an annular baffle 40 assist in the mixing of precipitates and water. 42 is the settling zone and 44 the mixing and recirculation zone which connects with the uptake zone 46 at the upper opening of the latter. 46 communicates with 42 at its lower opening 49. 48 is a motor-driven scraper or rake. A frustoconical funnel member 53 is mounted on the scraper and its lower opening 55 is directed towards a sludge pit 54. Recirculated precipitates pass up through 53 into the bottom of 46. Sludge thickeners 56 are rotatably driven by the same shaft S2 as the scraper and sludge is removed through the line 58. Recirculated precipitates from 42 are mixed with influent water in 46. Chemical treating agents are added through lines 60 and 62 and mix with influent water in 46. Treated effluents are recovered in the annular shaped collector trough 64 and withdrawn through line 66. In a preferred embodiment the T-connection 70 diverts excess flow through inlet conduit 72 to flow control tank 74 within which a weir 76 divides 74 into inlet and outlet compartments 78 and 80 respectively. 80 communicates with an annular distribution chamber 84 through flow control outlet conduit 82, and the chamber passes water into 20 through a plurality of holes 85 in the perimeter of 34. 76 may be of adjustable height to control the pressure head in 72.
