Abstract: 546,258. Ploughs. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd. (International Harvester Co.). July 22, 1941, No. 9248. [Class 6 (i)] In a roll-over plough having a main frame 18 supported on wheels 11, 12, an angularly adjustable draught bar 110, and a tool frame 19 pivoted to a transverse member 34 of the main frame and carrying right and left hand plough bottoms 26, 27, latches 46 which normally retain the tool frame against rotation, stops 70, 71 maintaining the main frame at different heights relatively to the wheels, and the latches 114, 115 securing the draught bar are all controlled by a lever 140 mounted to rotate a shaft 90 carrying cams operating the latches and stops. The stops 70, 71 on each side of the frame engage a transverse portion 69 of a bar 68 secured to a longitudinally extending part 64 of crank axle 13 of a wheel, the axle being pivoted in a bracket 44. When the transverse portion 69 of an axle is retained against the stop 71, the wheel serves as a furrow wheel. When the frame latches 46 are tripped, the revolvable tool frame is rotated by the forward movement of the plough, and when in a vertical 41 position with a transverse member 22 on the ground, the main frame is raised bringing the transverse portion 69 of the axle against the lower stop 70. The frame is then in a fixed position for transport. Each time the control lever 140 is pulled by a rope 141, the shaft 90 is rotated by a ratchet through 90 degrees. Starting with a set of plough bottoms on the ground, one pull of the rope releases the latches 46, and the tool frame is revolved by the forward movement to bring the other frame to a vertical position, and with the next pull of the rope, the other set of plough bottoms are brought into ploughing position. Miniature plough bodies rotated by the shaft 90, indicate the position of the plough bottoms to inform the operator which set is in transport position ready for lowering for ploughing The ploughing depth is adjusted by rod and screw mechanisms 74, 75 connected to the crank wheel axles and operated by handles 146, 147.

Abstract: 703,219. Suction cleaner filter bags. HOOVER, Ltd. April 18, .1952 [April 18, 1951], No. 9763/52. Class 8 (2). [Also in Group XVII] An open ended tubular gas filter bag 10, Fig. 4, for a suction cleaner is formed with front and rear walls and with side walls having longitudinal folds 11 to 15 into an opposite pair of which e.g., folds 12 is fitted one end of a reinforcing sleeve 17, forming a dirt trap having front and rear walls 24 and 25, 26 respectively of substantially the same width as those of the bag, and flaps 19, 20 at the other end which are folded along lines 28, 35 so as to lie against the exterior of the front and rear walls of the bag; the flaps 19, 20 being bonded to said bag exterior. The sleeve 17 is formed from a single blank cut along lines 33, 34, Fig. 1, to form extensions 21 of the flaps 20 and locking tabs 23.

Title: Improvements in or relating to the method of and means for the determination of the direction of a source of compressional waves
IPC: G01S3/14
Filed: 1931-03-31
Abstract: 378,033. Locating sounds. SUBMARINE SIGNAL CO., 160, State Street, Boston, U.S.A.-(Assignees of Atlas-Werke Akt.-Ges.; 16, Stephanikirchenweide, Bremen, Germany.) March 31, 1931, No. 9791. Convention date, April 30, 1930. [Class 118 (ii).] The direction of a source of sound of mixed frequencies is determined by receiving the sound at a plurality of spaced receivers, making a rough determination of the required direction by the " maximum " method and then increasing the accuracy of the determination by eliminating the low-frequency waves arriving from the source. In order to ensure that a true maximum is obtained and to distinguish between closely adjacent sound sources, the receivers may also be connected for listening binaurally without the use of the eliminating filters. The line of receivers 1 .. 6, Fig. 3, is rotated until it coincides with the wavefront of the arriving sound, whereupon a maximum indication is given in the telephone 22. This determination is first made with the switches 24, 25 in the dotted positions and the switches are then moved to the fullline positions, a high-pass electrical filter 23 being thus inserted in the circuit. A second determination is then made. The filter may eliminate all frequencies below 800 or alternatively below 2000 per second. In the modification shown in Fig. 4, the receivers 1 .. 6 are stationary and are connected through a compensator 43 to switches 60, 65. With the switch 65 closed and the switches 60, 61 in the dotted positions the receivers are connected to the telephones 62 for listening by the maximum method. The switches 60, 61 are now moved to the full-line positions, whereupon a highpass filter 23 and an amplifier 24 are inserted in the circuit, a further determination by the maximum method being made. Finally, the switch 65 is opened and the switches 60, 61 returned to their dotted position, the receivers now being connected for listening binaurally without the interposition of the filter.
Patent GB-571917-A (GB)
Title: Improvements in or relating to apparatus for use in the testing of metals
IPC: G01N3/10
Filed: 1943-06-18
Abstract: 571,917. Hydraulic apparatus; valves. SULZER FRERES SOC. ANON. June 18, 1943, No. 9820. Convention date, July 18, 1942. [Classes 69 (ii) and 135] [Also in Group XIX] Apparatus for carrying out creep tests on several pieces simultaneously at high temperature under a uniform load for a long time is characterised in that the loading is applied hydraulically. The test-pieces 1 are arranged in a ring between inner and outer insulating jackets 3, 4 heated by upper and lower coils 5, 7 and 6, 8. The outer insulating jacket 4 is rotatable about the ring, and has one or more observation windows 9 whereby any testpiece can be viewed through a microscope 9a. The test-pieces are loaded hydraulically by a plunger 10 or 10a in such a manner that if one of the test-pieces breaks, it does not affect the loading of the others. A low-pressure pump 28 delivers fluid through a cooler 30 to a highpressure pump 31, any surplus being fed to the low-pressure side of an accumulator 32. The high-pressure pump feeds a number of pressure regulating devices 13 individual to the test-pieces. The pressure to be exerted on the test-piece is controlled by a set of springs 16 of different strength compressed by a thumbscrew 17. Any variation from the required pressure causes a piston 15 to rise or fall so as to connect a port 21 in the piston with the inlet or exhaust port 20, 23. The pistons 15 are continuously rotated backwards and forwards by a pulsator device 26, 27 to render the regulating device sensitive. To prevent rapid changes of pressure in the cylinders 14, the pipes to the plungers 10 are throttled. If a test-piece breaks, the throttle prevents the loss of much fluid before a valve 38 cuts off the corresponding regulating device 13. The pipes 11 are connected to a common pressure gauge 37 through valves 36. Surplus highpressure fluid flows to the lower side of the accumulator 32, and passes through a port to the upper side when the pressure has built up. The fluid on the upper side lifts the regulating spring 33 when its pressure has built up, to return to the tank.
