Abstract: 387,645. Distributers for manures and seeds. PICCOLO, F., 10, Via Marsilio da Padova, Padua, Italy. May 1, 1931, No. 12896. Convention date, May 1, 1930. Void [Published under Sect. 91 of the Acts]. [Class 6 (i).] A machine for sowing seeds and fertilizer at spaced intervals in drills comprises rotary distributers fed from elevated hoppers and each provided with small radial buckets or reservoirs acted upon by springs so as forcibly to project the seeds and fertilizer in small heaps. Seeds are delivered from a hopper 1 by a rotary feeder 3 to a tube 6 leading to a funnel 7. Fertilizers are delivered from a hopper 2 through a valve-controlled outlet to a tube 8 also leading to the funnel 7, which is divided into a seed compartment and a fertilizer compartment. The seed and fertilizer pass from the funnel 7 to an adjustably divided chamber 17 above a rotary horizontal cylinder 24 having apertures normally closed by spring-controlled covers 26 which are opened by a blade 20 as they approach the chamber 17. Within the cylinder 24 are radial buckets 27 pushed outwards by the direct or indirect action of springs but normally held in position in the cylinder by a cam 18 engaging rollers on the parts carrying the buckets. As an open aperture passes beneath the chamber 17 seeds and fertilizer pass through it into one of the buckets 27, the aperture being then closed by its cover 26 and the bucket being carried round until it approaches its lowest position, when it is suddenly projected by its spring through the aperture. Its contents are thus discharged into a furrow made by a share 10 and they are afterwards covered by covering devices. The cylinder 24 is provided with a scraper 19 and the chamber 17 with a spring-controlled shutter to allow of the escape of foreign bodies. The spacing in the furrows may be varied by changing the driving gear.

Title: Improvements in or relating to machines for testing materials for wear
IPC: G01N3/56
Filed: 1935-05-02
Abstract: 455,995. Testing physical qualities of materials. BROWNSDON, H. W., 43, St. Agnes Road, Moseley, Birmingham, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. May 2, 1935, No. 13156. [Class 106 (ii)] Relates to machines for testing wear, more especially of metals of the kind in which a revolving or oscillating disc is adapted to wear a depression in the material to be tested and consists in the provision of a disc 1 which is moulded or shaped to an angle at the periphery so that the depression made is of oval or elongated diamond shape. The disc 1 is keyed to a spindle 2 mounted in bearings carried by arms 4 of the main body 5 of the machine. The specimen 6 is held by a screw 8 in a platform 7, the stem 9 of which slides without turning in a guide 10 and is pressed upward against the wheel by a loaded lever 12 with a constant force. The test may be carried out with oil lubrication or dry and may be kept at a high temperature by hot oil or at low temperature with oil near freezing point. The test usually lasts for five minutes at a predetermined speed and the length of the depression is taken as the measure of the wear. By making measurements over increasing intervals of time, a point is reached at which no further increase in the length of the impression takes place, thus permitting a calculation to be made as to the load a material will withstand without giving rise to appreciable wear under the conditions of lubrication used.

Patent GB-132826-A (GB)
IPC: C02F3/20
Abstract: 132,826. Jones, W., and Jones & Attwood. April 27, 1918. Aerating; tanks.-Tanks for treating sewage with air are so formed that the motion of the sewage induced by the ascending air-bubbles is so directed as to cause the air to be retained in the sewage longer than it otherwise would be, and to hinder the accumulation of sludge on the bottom of the tanks. To effect this, the bottoms 1 and sides or partitions 2 of the tanks are connected by portions 3 curved as shown to a large radius, so that a circulation is induced as shown by the arrows. To assist this circulation, the sides and partitions 2 may be formed with overhanging portions 5 shaped as shown. The air-diffusers 4 are preferably placed at the foot of the partition 2, and the openings 7 between the different divisions of the tank are adjacent to them; but they may be placed in the middle of the tank, in which case the bars shaped like the overhanging portions 5 are arranged across the tank above them. In the arrangement shown, the plane of the circulation is transverse to the general flow of the sewage, but it may be parallel thereto. Similar arrangements may be made in a sewer and the sewage treated therein. The air supply may be periodically increased to assist in moving sludge. The arrangement is stated to be applicable to the apparatus described in Specification 111,720.

Title: Improvements in means for safeguarding electric igniters of blasting detonators against accidental firing
IPC: F42B3/18
Filed: 1942-09-21
Abstract: 563,345. Lightning arresters. ROLFES, Ltd., ROLFES, H. J., and HALLIDAY, E. C. Sept. 21, 1942, No. 13284. [Class 38 (iv)] [Also in Group XXI] Means for safeguarding electric igniters of blasting detonators against accidental firing by atmospheric electricity comprises the combination of a " filter means" with a self-inductance means, the self - inductance means being located in the igniter and/or blasting circuit leads between the-filter means and the igniter or igniters. By the use of this combination the flow of current caused in the leads by, e.g. lightning discharges, is choked back or prevented from reaching and setting off the igniters. The filter means comprises an earthed mass of a material which will exhibit a high resistance at voltages of the magnitude used for intentionally firing the igniter and a low resistance at substantially higher voltages produced by electrostatic charges caused by atmospheric electricity; such a means is described in Specification 555,969. Fig. 1 shows a copper tube 2 (which is earthed) containing a filter 5 and a self-inductance means 1 in the form of a soft-iron core. The two leads are wound in opposite directions around the legs of the core, so that the two inductances add together. The lead ends 3b, 4b are connected to the igniter. Points 3d, 4d on bared parts of the leads pass through the filter promote passage of current to earth (see Specification 556,071). A rubber plug 10 separates the filter and the core, and rubber plugs 6, 7 close the ends of the tube 2. In modifications, (a) the filter, core and detonator are all contained in an aluminium casing, the filter being earthed by connection to the copper casing of the detonator and to the aluminium casing, and (b) one core may serve for a number of detonators connected together in series or in parallel. The core may be flexible, e.g. it may be made from a length or strands of thin soft iron wire.
