Title: Method and apparatus for suppression of noise in seismic data
IPC: G01V1/24
Filed: 1975-06-10
Abstract: 1497885 Seismic data processing GEO SOURCE Inc 10 June 1975 [27 June 1974] 24803/75 Heading G1G In a seismic system wherein the amplitudes of received seismic signals are normalized, prior to recording them, by applying gain factors sufficient to bring their amplitudes inside a predetermined amplitude range, the gain factors applied are compared with reference gain factors and the recording is blocked if the gain factor applied in any given part of the reception period is significantly less than the reference gain factor for that part, whereby spurious high-amplitude noise signals are suppressed.  Fig. 1 shows the typical amplitude decay 64 of a seismic signal with time, and a noise spike 5. The processing for one channel of a multi-channel seismic system is illustrated in Fig. 2. Amplifier 40 provides coarse adjustment of the received seismic signal level to be inside the predetermined range, e.g. 33 to 34, Fig. 1, and a further fine adjustment is made at 50. For each part A 1  A 2 , A 2 A 3 , &c. of the reception period the minimum gain factor used in that part is detected at 52, and stored at 61. Reference gain factors for partperiods A 1 A 2  &c. are stored in memory 62. When a set of received signals, as resulting from a sequence of seismic shots, is being processed the minimum gain factors determined for the first signal are used as the reference gain factors at 62; thereafter the reference factors are updated at 54 by replacing them with lower factors if such are encountered in processing the second and subsequent signals. At 56 the gain factors applied in sub-divisions of any part-period A 1 A 2  &c. are subtracted in turn from the reference gain factor for that part-period and if the difference exceeds a limit value then a reject signal is generated. This reject signal is extended at 58 and used to block the recording for a time considered sufficient for a noise spike to decay to a negligible value. The reject signal and the extended signal also prevent the prevailing gain factor from being considered by device 52 and prevent spurious up-dating of the reference gain factor at 54. The recorder is used to provide a stacked record.

Abstract: 704,568. Mixing appliances. EXCELSIOR MOTOR CO., Ltd. Oct. 24, 1952 [Oct. 24, 1951], No. 24807/51. Class 86 Lubricating oil and fuel are mixed in the fuel tank of an engine by subjecting the imperfeotly mixed oil and fuel to a current of air introduced below the level of the surface of the mixture so as to produce a bubbling which aids dispersion of the oil in the fuel. In a motor cycle fuel tank a length of pipe 15, sealed at the end 17 and having spaced orifices 16 is disposed along the bottom of the tank in the same vertical plane as the filler cap 14 and is connected by an imperforate pipe 18 to an inlet fitting 19 having a nozzle 20 adapted to be connected to a source of compressed air. If the device is to be used with a valveless tyre inflating pump the inlet fitting 19 is provided with a non return valve. In Fig. 3 (not shown) a cylindrical fuel tank of the kind employed for engines of industrial plant or for appliances such as mowing machines is provided with a horizontal length of perforated piping parallel to the tank axis in the base portion of the tank, connected to an inlet fitting in the highest point of the tank diametrically opposite the base portion. The fuel tank may have fitted thereto or may incorporate its own air pump provided with a manually operable handle. The inlet fitting may be positioned below the normal level of fuel, in which case a valve, . e.g. a spring pressed ball valve, is provided to prevent egress of fuel through the pipe The active length of the pipe may be flattened to cover a substantial surface area in the base of the tank.

Title: A composition for the cultivation of mushrooms and process for preparing same
IPC: A01G1/04
Filed: 1935-09-06
Abstract: A material in which mushrooms are grown consists of bran and fine sawdust or finely chopped straw mixed together into a paste with water in which rice grains have been washed, or which has rice powder in it.  The mixture is packed into a glass pot or other vessel which is then closed with a plug of cotton wool or the like, a space being left below the plug.  The top of the container is then covered with greaseproof paper or a lid and the container subjected to the action of steam for two or three hours to ensure sterilization.  After cooling, the cover and plug are removed and mushroom spawn is inserted in a hole made in the material before sterilization.  The plug is afterwards replaced and the container deposited in a dark place until white spawn appears on top of the material, the plug then being removed and the container left in a damp place until the mushrooms appear. The mixture and growing mushrooms are sprayed periodically.

Abstract: 704,282. Photo-electric control systems. BAADER, R. Oct. 30, 1951 [Dec. 24, 1948], No. 25359/51. Class 40 (3) [Also in Group VI] Fish are positioned with all their backs or all bellies facing the same direction for dropping through a hopper 25 to a fish dressing machine by mechanism in which a light-detector, such as as a photo-electric cell actuated by the greater light reflected thereto by the belly 1, actuates mechanism to rotate a fish through 180 degrees if originally facing the wrong direction. Each fish falls through an elliptical hopper 1 into an elliptical tube 3 closed at the bottom by a pair of pivoted flaps 6. Four such tubes are arranged around a rotary structure 2. As each tube 3 is moved into the position 11 a light beam from 12 directed through a slot 13 on to the fish is reflected to a light detector 14. If sufficient light is reflected as from the lighter belly, a current flows to a relay and amplifier control 16 which energizes an electromagnet 17. 17 attracts an armature 18 of a lever 19 whereby an arcuate toothed rack 22 is moved in, to be engaged by teeth 23 on the tube 3. As the teeth 23 roll along the fixed length of the rack 22 the tube is rotated through 180 degrees whereby the back of each fish then faces outwards. The fish is discharged from its tube 3 as it is swung round past position III whereby a cam roller 28 on 3 contacts a cam 27 on the fixed discharge hopper 25. The cam roller operates levers to open the flaps 26 allowing the fish to drop into the hopper 26 for feeding to a fish-dressing machine.

The traction and.steering head preferably comprises a differential for the two driving wheels, and is preferably steered by a pair of handles mounted directly thereon, the forward and reverse switches being mounted one on each handle and being so connected that it is necessary to operate one of said switches and the foot treadle before the motor is energised. The truck, Fig. 1, has a frame 10 with loading platform 11, battery box 17 and operator's platform 79. Rotatably mounted on the frame 10 by ball bearings 27 is the traction and steering head 22, (see also Fig. 3) to which is attached a pair of vertical columns 92 and steering handles 93, Fig. 2. Such head comprises an electric motor 20 which drives a countershaft 32 by chain and sprockets, the countershaft transmitting the drive to the differential 48, 50 and driving wheels 52 also by chain and sprocket. The countershaft is provided with a pair of brake shoes 55 pivoted at 60 the brake being normally kept on by tension spring 75 acting through lever 68, rod 63, shoe member 62 and rod 60, but are released when the operator depresses foot pedal 77 to raise rod 81 connected at 84 to the upper end of the tension spring 75. Partial depression of the foot pedal 77 causes the battery to be connected to the motor through a resistance whereby a low speed is attained, and full depression short circuits the resistance and gives full speed. The necessary electrical connections are made between the control box 87 which is mounted on the frame 10, and the motor which is contained in the rotatable traction and steering head 22 by means of brushes and slip rings 97, 96, Fig. 3, mounted concentrically with the axis of rotation. Mounted on the handle 93, Fig. 2, are forward and reverse switches F, R actuated by push buttons and so arranged that the 'motor will not function until one of these switches is operated and the foot treadle 77 is depressed. The load on the platform 11 is raised by hydraulic ram supplied with fluid from the pump 14 on actuation of the pedal 15; the pedal 16 controls the lowering of the platform.
