Title: Improvements relating to motor-generators of the vibrating armature type for the interconversion of alternating currents and mechanical vibrations
IPC: E06B7/18
Filed: 1937-09-03
Abstract: 489,075. Electromagnetic resonators. STANDARD TELEPHONES & CABLES, Ltd. Sept. 3, 1937, No. 24152. Convention date, Sept. 16, 1936. [Class 40 (iii)] [Also in Group XXXV] A vibratory armature type combined motorgenerator comprises a vibrator with parts of opposite polarity disposed in air gaps in a core structure consisting of two similar core sections providing parallel paths for the vibrator flux, the magnetic mid-points of the two sections being interconnected by a further core section and the input and output coils being disposed on either side of said mid-points. In the form shown, each vibrator consists of magnetic reeds 17, 18 connected by rods 20 extending from a permanent magnet 19 into the air gaps between cores 11, 12, 14 and 15 and producing fluxes represented by the full line arrows. When A.C. is applied to the coils L<1> producing a flux represented by the dotted arrows the interaction of the fluxes causes vibration of the two upper reeds which is transmitted by the rods 20 to the lower reeds 17, 18, thereby modulating the direct flux in the lower part of the core and inducing current in the coils 2. The permanent magnets may alternatively connect the two upper and the two lower reeds. The core 15 may carry a winding in series with coils L<1> and core 14 may have one in series with coils L<2>. By adding condensers to the primary and secondary circuits, the structure may be used as a band-pass filter.

Title: Apparatus and method for determining in situ the soil permeability and the water pressure
Inventor: JONG GERARD DE JOSSELIN DE
IPC: E02D1/00
Filed: 1956-08-10
Abstract: 817,295. Testing physical properties of soil. STICHTING WATERBOUWKUNDIG LABORATORIUM. Aug. 10, 1956, No. 24591/56. Class 106 (2). Apparatus to determine in situ the permeability of water-bearing soil comprises a tube 1 to be driven into the soil, having a closure 8 at its upper part and fine openings 2 in its lower part, a water-pressure gauge 5 connected with the interior of the tube 1, means 12 for filling the tube 1 with water, and an elastic bellows or the like 14. In operation, the tube 1 is driven into the soil to a desired depth, and a tap 10 closed. The tube is then filled with water and a cap 8 fitted to the upper end. Water will flow through the openings 2, which are covered by a filter, either into or out of the tube 1, until equilibrium is reached between the pressure of water in the tube 1 and the pressure of water in the surrounding soil. This pressure can then be read directly on an electric measuring instrument 7 connected to the gauge 5 which is of the capacitative type. To determine the permeability of the soil, a tap 11 is opened and vessel 14 filled with water through the funnel 12. The vessel 14 is then compressed, so that water in the funnel 12 rises, and the tap 11 is closed. The bellows are then released and the tap 10 opened. The vessel 14 will try to regain its initial volume thus forming a degree of vacuum in the vessel 14 and tubes 4, 1. Thus water is sucked up from the soil through the holes 2, and the rate of change of pressure of water in the tube, which may be recorded, gives an indication of the permeability of the soil. Another embodiment provides a plurality of bellows each of which may be connected to the tube 1 according to the size and flexibility required for best results with the type of soil under test. A further embodiment uses a liquid which does not mix with water (such as mercury) in a U-tube, to provide the partial vacuum required.

Abstract: 1,134,033. Method of making pressure vessels. STRUCTURAL FIBERS Inc. 6 June, 1966, No. 25043/66. Heading B8G. [Also in Division F4] A method of producing a pressure vessel comprises the provision of an inflatable bladder, surrounding the bladder with reinforcing strands impregnated with a heat curable material, inflating the bladder to a degree causing the reinforcing strands to be tensioned, and then heating the resulting body to cure the impregnating material. In Fig. 4 the bladder 16 is partially inflated and passed through the plates 40, 41 to cause a plurality of meridional laid strands 35 to be applied to the bladder in the manner shown. The strands are secured as at 48 to each end of the bladder. A plurality of such passes may be made. Hoop windings may also be applied either directly on to the meridional strands 35 or in a preformed tube into which the body is slid. The strands are impregnated with said heat curable material before or after winding, the bladder 16 is inflated to a predetermined pressure, and the whole is then heated to cause the impregnating material to be cured. The Specification describes embodiments in which the meridional strands 35 are replaced by helical windings. Substantially spherical shaped embodiments are also described. Fig. 8 shows a vessel 70 made by the invention. An end fitting 76 is secured to one end of the bladder 75 and the opposite end (not shown) is provided with a conduit that may be connected to a fluid source under pressure. Longitudinal strands 77 are applied as described with reference to Fig. 4 and tied to the fitting 76 by a cord or wire 78. A cord or wire 79 is wrapped circumferentially around the bladder to secure the strands 77 in position. A hoop wound shell 80 is then telescoped over the bladder 75. A rim 82 of metal, plastics or other suitable material may be used for securing a cover, not shown, over the open end of the vessel. The strands 77, 80 are impregnated before or after application to the bladder. The bladder is then inflated and subjected to heat curing.
