Abstract: 845,547. Fabric for bearings &c. WHITE, C. S. Oct. 16, 1956 [Nov. 4, 1955(2)], No. 31494/56. Drawings to Specification. Class 142(4). [Also in Groups XXVI and XXXIV] A fabric for bonding to a bearing or sealing member to constitute the working surface thereof comprises threads of synthetic resin having a low coefficient of friction on one surface and threads more easily bondable to the member on the other surface. A two-ply fabric has one warp of low-friction threads, the other warp and the weft being of bondable threads; the plies are bound together by weft threads producing a 3:1 twill weave on the bondable surface. Another two-ply fabric has one ply plain-woven from low-friction warp and weft and the other plainwoven from bondable warp and weft, the plies being spaced apart by numerous stuffer warp threads and stitched by binder warp threads. A single-ply tubular fabric is woven 4:1 twill from a low-friction warp and a bondable weft. The low-friction threads may be of polytetrafluoroethylene, monochlorotrifluoroethylene, nylon, polyester terephthalate, polythene, or a copolymer of vinylidene chloride and vinyl chloride. The bondable threads may be of cotton, rayon, cellulose ester, wool, glass or nylon. Canadian Specification 675,632 is referred to.

Abstract: 467,888. Stapling fibres. MAURER SOC. ANON., ING. A. Nov. 21, 1936, No. 31935. Convention date, Dec. 5, 1935. [Class 120 (iii)] In producing staple fibres one or more fluid jets are directed on to the strand of artificial fibres C, Fig. 1, in such a way as to twist the strand into the form of a rope which is thereby stiffened to withstand the cutting action. The fibrous material C passes over a guide roller B and through a funnel D into a chamber F. A fluid, e.g. spinning solution or water is supplied through a conduit E to the chamber F, Fig. 3 and the course of the fluid is such that it twists the strand into rope form, the strand issuing thus at G and being cut by rotatable cutters H.

Abstract: 281,339. Aktiebolaget Svenska Flaktfabriken, (Assignees of Olsson, J. G.). Nov. 29, 1926, [Convention date]. Drying.-Condensation of the moisture in the air rising from the steam-heated cylinders 1 of paper drying machines is avoided in the drying- space by air drawn through a shaft 12 by a fan 14 and forced through a preheater 5. disposed in the path of the moist air exhausted by a fan 7, into a damper-controlled pipe 22 having a heater 28 through which the condensate from the cylinders is passed and perforated branch pipes 24 for delivering the air at a temperature of about 40‹ C. into the space 23 beneath the cylinders; the air rising through the perforate partition 27 and against the ends of the cylinder to the ceiling opening 4. The dimensions of the openings 26 in the partition 27 are graduated to distribute the air in proportion to the evaporation effected at the different parts of the drier. Perforate pipes 30 are connected to the pipe 22 to deliver air into the drying-space beneath the ceiling. Ventilation of the drying-space is effected by air drawn through a shaft 11 by a fan 13 and forced through a preheater 6 into a perforate pipe 15 having perforate branch pipes 18; the air is delivered at a temperature of about 20‹ C. The ventilation air may be by-passed through a damper-controlled pipe 34 to the heater 5. In a modification, the pipe 22 may be provided with additional longitudinal perforate branch pipes in the space beneath the cylinders.

Title: Improvements relating to the operation of superchargeable internal combustion engines
IPC: F02B37/16
Filed: 1961-09-06
Abstract: 941,532. Superchargeable engines; cycles. DAIMLER-BENZ A.G. Sept. 6, 1961 [Sept. 8, 1960], No. 32030/61. Heading F1B. A superchargeable engine using volatile fuel comprises means for adding exhaust gases to the charging air drawn into the engine. In order to obtain the required final compression temperature the amount of exhaust gases to be added is reduced as the charging compression ratio is increased. As shown exhaust gases flow through the passage 10 into the exhaust gas turbine 11. The turbine 11 drives the supercharging compressor 12. The exhaust gases flowing into the branch 16 will lift the non- return valve 17 during peaks of pressure in the passage 10. The exhaust gases penetrate periodically into the chamber 19 of the separator 18 are cleaned of soot therein and flow through the branch 20 to the passage 14. A throttle valve may be provided in place of the non- return valve 17. In Fig. 4 a rotary pump 27 can draw air from the passage 14 and inject it into the exhaust gases in the passage 10. If the cooled exhaust gases flowing into the turbine have an excessive temperature the valve 15 is adjusted to reduce the flow of exhaust gases such a control can be obtained by means of a thermostat in known manner. If required the exhaust gas turbine may be designed with a smaller cross-section so that the maximum charging compression ratio is obtained at low engine speeds. The charging pressure may then be kept substantially constant at high engine speeds by causing a quantity of exhaust gas to by-pass the turbine. The exhaust gases may be added to the charging air upstream of the compressor. The invention is applicable to motor vehicle engines capable of operating with more than one fuel. Benzol may be used as the fuel.

A single air draft device 20 (Fig. 1) is connected by valves 14 to apply successively to a foraminous member 12 suction to retain a label 57 and then air pressure to apply the label to an article such as a magazine 54. The valves may consist of plates 28, 29 pivoted to close ports (24) . . . (27) (Fig. 4, not shown). The valves are moved by a linkage (31), (32), (34), against the bias of springs (39), when a constantly running motor (43) (Fig. 6, not shown) is connected by a slipping clutch (46) to turn a lever (38) into engagement with a stop (50). In an alternative construction plates (90). (91) (Fig. 7, not shown) are turned in unison through a linkage (100) (Fig. 8, not shown) from a solenoid (101), to connect either the inlet or outlet of a pump (87) to the foraminous member. An adjustable bleed 76 (Fig. 1) or (110) (Fig. 7, not shown) limits the degree of vacuum. The labels are stripped from a carrier sheet 58 (Fig. 1) when this is drawn round a knife edge 61 adjacent the foraminous member 12. The operations are controlled through preset delays from a photo-cell device 65 detecting magazines on an endless conveyer 53.

[Class 106 (i)] A liquid volume measuring device of the continuous meter type is characterized in that the transmission connecting the meter to' a trip totalizer comprises a differential mechanism of which the incoming shaft receives the movement of the meter and of which the movement of the outgoing shaft is transmitted to the trip totalizer, means being provided for locking the differential housing except while the trip totalizer is being reset to zero. The meter 1 drives the shaft 4 actuating the differential 6, 7, 7<1>, 10 driving the outgoing shaft 11 driving through pinions 12, 13 the trip totalizer 14-17. The housing 5 of the differential has integral with it a notched wheel 23 which is normally locked by a member 25 under the action of the spring 27. The trip totalizer is reset to zero by rotating the handle 22 and shaft 21 through one revolution this rotation of the shaft 21 also causing rotation of the cam 30 through bevel pinions 32, 33 with consequential movement of the wheel 29 from the recess 34 of the cam and movement of the member 25 from engagement with the notched wheel 23 thus freeing the differential housing 5. The angle at the centre corresponding to one tooth and one notch of the wheel 23 is such that the quantity of liquid delivered through the meter during rotation of the wheel through that angle is less than the permitted tolerance.
