Title: Improvements in electromagnetic devices in which a body is moved between two stable end positions
IPC: H01F7/122
Filed: 1960-06-30
Abstract: 958,501. Electromagnets. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 30, 1960 [July 3, 1959], No. 22939/60. Heading H1P. A ferromagnetic body is held in either of two stable end positions by at least one, ferrite, permanent magnet, and is moved between them by electromagnetism provided by a current pulse. As shown, the body 1 comprises the permanent magnet and holds itself against either end of the soft iron cylinder 3, but is sent from one end to the other by repulsion when the appropriate coil 4 or 5 is pulsed. In one alternative arrangement (Fig. 2, not shown), the body is of soft iron and there is a permanent magnet at each end of the cylinder which is now of brass; a single coil extends between the ends and the pulse is applied for the first half of the travel only, the polarity being such that the body is repulsed from whichever is the nearer magnet. In a second alternative (Fig. 3, not shown), the body is again a permanent magnet which now traverses between the soft iron cores of two electromagnets connected in series whose polarities are such that the body is repulsed by one and attracted by the other. In this case the pulse length is immaterial but its sign must be appropriate for the direction of travel required.

Abstract: 1,197,007. Poultry drinking fountains. PLASSON MAAGAN MICHAEL INDUSTRIES Ltd. 15 May, 1968, No. 23004/68. Heading A1M. [Also in Division F2] A suspension-type poultry drinking fountain comprises a water trough 20, a valve 14, controlling the flow of water to the trough, and a hanger 2 from which the trough is suspended by means of a resilient mounting so that the valve 14 operates automatically to maintain the water level in the trough 20, the fountain being characterized in that a weight, preferably a water-filled receptacle 50, is suspended directly from the hanger 4 so as to minimize swinging of the trough 20. Wings 40, integral with the hanger 2, support, by means of bail arms 44 passing through tubes 46 integral with the trough 20, the water-filled receptacle 50, whose inertia restrains the trough 20 from swing- ing. Ribs 56 within a trough-supporting bell 24 are optionally provided to reduce the small clearance 54 between the bell 24 and the receptacle 50.

Title: Improvements in or connected with means for launching aircraft
IPC: B64D5/00
Filed: 1932-08-19
Abstract: 402,895. Aircraft carrying other aircraft. MAYO, R. H., 39, St. James's Street, Pall Mall, London. Aug. 19, 1932, No. 23286. Addition to 400,292. [Class 4.] In order to ensure ready separation of the two components of a composite aircraft of the type described in the parent Specification the upper component is so mounted on the lower component that the resultant reaction between the two acts behind the centre of gravity of the lower component. In order to ensure that separation does not take place until a predetermined excess lift is exerted upon the wings of the upper component one or more locking devices each comprising a hook 3 associated with one component engages a restraining projection 4 on the lower component, the hook or the projection being arranged to yield as the lift co-efficient of the wings of the upper component is increased and to give way entirely when the pre-determined excess lift is developed. In one form, Fig. 3, the engaging part of hook 3 comprises an integral portion 6 and a pivoted portion 7 held in position by a spring 9. As the angle of incidence of the wings of the upper component is increased hook 3 moves angularly until part 6 leaves projection 4 which is then engaged by pivoted part 7. Axle 1 now moves upwardly in socket 2 and as the excess lift increases the resistance of spring 9 is overcome until part 7 rotates sufficiently to free the hook 3 from projection 4. According to a modification the whole of the engaging part of hook 3 may be pivoted in the manner of the portion 7.

The ring 16 is surrounded by a gas supply chamber 27 for admitting gas to the throat through an annular discharge opening or ports 29. Gas leaking through the tiles 61, 62 escapes to the furnace through passages 62. Additional gas is supplied to the furnace from the chamber 18 for ignition or stabilization purposes through tubes 75. Air is supplied at a higher pressure than the gas pressure to an annular space 73 surrounding the furnace opening to ensure leaking gas passing into the furnace. An angularly adjustable baffle 80 may be provided to regulate the gas flow around the chamber 80. The chambers 17, 18 may be provided with an insulating lining 10a.
