Title: Improvements in or relating to cavity resonators
IPC: H01P7/06
Filed: 1946-10-10
Abstract: 627,513. Electric resonators. WESTERN ELECTRIC CO., Inc. Oct. 10, 1946, No. 30271. Convention date, May 12, 1945. [Class 40 (viii)] A hollow cylindrical resonator has a tuning piston which leaves a gap between its outer edge and the chamber wall which permits oscillations of a TM1 mode to pass behind the piston into a part of the resonator with high resistance walls that attenuate these waves. The resonator comprises a chamber 11 of aluminium with an interior plating of silver. A plated disc 14 mounted on an adjusting stem 13 varies the mid-band frequency of the cavity which is cyclically varied by a plate 23 moved by an eccentric 20. A coupling loop 25 excites the resonator in a TE mode and an output loop 27 is also provided. A gap 29 between disc 23 and the chamber 11 does not affect the particular TE mode but tends to attenuate and change the frequency of undesired TM modes that are inevitably set up. In addition, the chamber 11 is not provided with a highly conductive plating behind the disc 23 so that there is marked energy dissipation by the TM modes which set up currents across the gap. Apertures in the form of slots or holes may be made in disc 23 in regions of weak field for the desired TE mode to aid further in suppressing the undesired modes. Similar construction may also be employed in connection with disc 14.

Filed: 1971-07-01
Abstract: 1352198 Laminates; perforating plastics material GENERAL ELECTRIC CO 1 July 1971 [2 July 1970] 30866/71 Headings B5N and B5A A perforated reinforced plastics material member is produced by pressing a reinforced partially cured plastics material sheet, e.g. glass cloth impregnated with partially cured epoxy resin, towards a mould surface provided with studs so that the studs project through the sheet while the sheet is moulded to a desired shape by the mould surface and studs, and then curing the plastics material sheet while pressing it towards the surface. A plurality of sheets of reinforced partially cured plastics material may be pressed over the studs. The studs may be at least partially elastic, e.g. of polyurethane, and may be coated with a release agent, e.g. polyvinyl alcohol, before pressing the sheet material thereon and the member may be removed from the mould surface after curing. Alternatively hollow rigid studs may be used, e.g. produced by depositing copper, nickel, cobalt or an alloy thereof on a mandrel and then removing it from the mandrel, the mould remaining as a part of the member and a portion of each stud projecting through the sheet being removed, e.g. by disc grinding, or the tip of each stud being opened and pressed on to the laminated body, leaving open perforations through the sheet. After pressing a plurality of sheets of reinforced partially cured plastics material over the studs the laminations may be covered with a polytetrafluoroethylene film and compacted under pressure, e.g. with a vacuum bag, autoclave or matching mould, and curing effected by heating, e.g. at 300‹ F. for two hours under a pressure of 50 psi. The perforated plastic laminated member may be used in the fan portion of an aircraft turbo-fan engine.

Title: Improvements in artificial respirators
IPC: A61M16/00
Filed: 1956-10-10
Abstract: 798,250. Artificial respiration apparatus. RENVALL, B. Oct. 10, 1956 [Oct. 12, 1955; Oct. 12, 1955], No. 30876/56. Class 81 (2). A bellows pump for artificial respiration has a connection from the handle to a valve which, in its two positions, connects a face mask for forced inhalation and free exhalation. The bellows 4 is connected through a slide valve assembly 16 to the lungs, the valve being such that when the slide 21 is to the left, the lungs 32 are connected to atmosphere through outlet 24, but when the slide 21 is to the right, the lungs are connected to the bellows through pipe 10. Movement of the valve slide is effected by connecting the handle 40 to a diaphragm 43 so that as the handle is pressed down to actuate the bellows air is initially compressed in tube 15 and, acting on piston 18, drives the slide to the right. In another form actuation of the valve is effected by a resilient bulb, mounted around the pump handle, which is squeezed at each forced inhalation stroke. In a further modification the bellows is divided into two chambers, one of which withdraws air from the lungs as the other takes in air for the subsequent inhalation stroke (see Fig. 7 (not shown)).
