Filed: 1926-12-29
Abstract: 287,963. Wilsdon, W. E. Dec. 29, 1926. Seed drills. - In seed drills or distributors having seed-distributing wheels or the equivalent mounted in casings on the coulters, the casings are made with one end removable so that the seed-distributing wheels or equivalent may be interchanged for varying the distribution auxiliary ground wheels preferably being provided for driving the distributing - wheels. The upper part of the coulter a mav be slotted to fit on a forked carrier b on an ordinary drill. The coulter is provided with a flat cylindrical casing a<1> closed at one side and fitted with a removable cover d at the other. A spindle c<1> mounted in the casing a' and cover d carries the interchangeable recessed seed wheel or disc c. The seeds pass into the casing a' from a hopper e through a shoot a<5> and inlet a<2> and they are discharged in groups periodically between guide plates a<4>. The outlet a<3> from the casing is of substantial size and at some distance from the ground so that the seeds mav be scattered in the furrow. The closure plate or cover d may be of sheet metal and formed with an extension to form the shoot a<5>. The cover d may be secured by the extension being held between the sides of the coulter by friction. The spindle c' may be extended to carry a driving-wheel running on the ground. This may consist of a boss carrying radial spokes or arms, or a sheet-metal disc provided with teeth having extensions bent out laterally. The distances between the groups of seeds may be varied by substituting for the seed wheel c a wheel having a different number of recesses or by substituting for the driving- wheel a wheel having a different diameter. To allow for the driving-wheel being of a different diameter the casing a' may be adjustably mounted on the coulter a. The driving-wheel may be mounted on a separate adjustably mounted spindly and may drive the spindle c<1> by gearing. The spindle c<1> may be driven from any rotary part of the drill.

Title: Insulating materials
Inventor: ASHPOLE RAYMOND SIDNEY
IPC: C04B28/24
Filed: 1962-08-28
Abstract: An electrically-insulating material is made by mixing asbestos flock with an aqueous colloidal dispersion of silica, impregnating a woven asbestos material with the mixture, and heating so as to allow the water to evaporate. Preferably the dispersion contains 30% silica by weight, and preferably 3 parts by weight of the dispersion are mixed with 2 parts of asbestos flock.  The asbestos material may have previously been saturated with the silica dispersion and dried.  The impregnated tape may be wound on to the stator-conductors of a dynamoelectric machine to provide inter-turn insulation. Before the tape is applied, mica strips may be secured to the conductors by adhesive, the tape being then wound over the mica. Two layers of tape comprising mica flake attached by adhesive to glass fabric backing may then be applied in "butt-lap" configuration. A suitable adhesive for the above purposes is a silicone varnish.  Further impregnated tape may then be laid over the mica-glass tape to the desired thickness. The whole assembly is now heated under pressure to dry the insulation inserted into the machine, after which the whole unit is heated in nitrogen at 400 DEG  C. to dehydrate and cure the cement. Insulating material may also be made by laminating the impregnated asbestos tape or sheet with or without incorporation of mica-glass tape, heating under pressure and then heating at, e.g. 400 DEG  C. in air not under pressure.ALSO:An electrically insulating material is made by mixing asbestos flock with an aqueous colloidal dispersion of silica, impregnating a woven asbestos material with the mixture, and heating so as to allow the water to evaporate.

Abstract: 1,068,755. Stapling and nailing machines. SIGNODE CORPORATION. Aug. 4, 1965 [Aug. 24, 1964; Sept. 8, 1964], No. 33390/65. Heading B4C. A fastener driving tool for driving nails and staples into a workpiece comprises a driving piston 8 movable in a cylinder 51 which is connected, via a chamber 21 defined by a removable cap 19, with a compressed air reservoir 4, the flow of air to and from the cylinder being controlled by a pilot, main and exhaust valves 33, 14 and 45 respectively. The main valve 14 is formed with a head 15 adapted to normally close a port 16 leading from the reservoir into the chamber 21 and with a piston member 25 slidable in a chamber 28; the interior of the chamber communicates with the reservoir 4 via a port 30 and passage 36 in the main valve. The pilot valve is in the form of a ball 37 normally urged by a spring 36 on to a seat 38. In operation, compressed air acts on the piston 25 via port 30 and passage 36 to maintain main valve closed. Upon actuation of a trigger 34 the ball is lifted off its seat, so as to vent the chamber 28 thereby allowing the main valve to open so that compressed air passes into the cylinder via chamber 21 to drive the piston 8 on its working stroke; in the open position of the main valve the exhaust valve 45 closes an exhaust port 49. When the trigger is released, the ball valve re-seats so that pressure builds up in the chamber 28 thereby closing the main valve and opening the exhaust valve as shown. Pressurized air then passes via a port 52 to act on the underside of the working piston so as to return it to the raised position.
