Title: Improvements in or relating to electromagnetic relays
IPC: H01H51/28
Filed: 1956-02-14
Abstract: 792,699. Electromagnetic relays; electricallytripped switches. WESTERN ELECTRIC CO. Feb. 14, 1956 [Feb. 17, 1955; Feb. 17, 1955], No. 4596/56. Class 38 (5). A relay arrangement including a number of sealed reed units 5, Figs. 2, 3, 4, each unit comprising a pair of magnetic reeds 7 sealed into the ends of a glass enclosure 8, the free ends of the reeds being normally separated but brought together to complete a circuit by application of a magnetic field as disclosed in Specification 522,798, comprises an H-shaped laminated core structure 2, 3, 4 energized by a coil 1. The vertical limb 2 passes through the coil whilst the several laminations of the upper and lower horizontal limbs 3, 4 have curved portions which partially surround and resiliently engage the ends of the enclosures 8. Insulating plates 11 carry terminals 9 connected to the reeds 7 by members 10. Energization of the coil 1 thus causes closure of all the reeds. As shown, however, the units 5 are polarized by curved permanent magnet plates 12 extending between the plates 11. These plates 12 may be strongly magnetized so that the reeds are normally held closed, the reeds being released by energization of the coil. Alternatively, the plates 12 may be less strongly magnetized so that when the reeds 7 are closed by energization of the coil they are retained closed by the plates, energization of the coil with opposite polarity releasing the reeds. In another construction, Fig. 8, four sealed reed units 41 are mounted within a coil 46, the assembly being held together by a pair of magnetic members 43 having curved end-portions 42 resiliently engaging the units.

Title: Improvements in and relating to seaplanes
IPC: B64C35/00
Filed: 1935-02-13
Abstract: 433,925. Seaplane alighting- gear. BLACKBURN AEROPLANE & MOTOR CO., Ltd., and RENNIE, J. D., Seaplane Base, Brough, near Hull. Feb. 13, 1935, No. 4631. [Class 4] A seaplane has its float, boat, or a section of the float or boat arranged to be raised or lowered by mechanism which produces a longitudinal tilting effect so as to enable the optimum angular setting between the float, boat or section and the wing for take-off and also the best setting of the wing relatively to the pontoon (with or without the hull or body against which it may be retracted) for flight conditions to be obtained. Figs. 1 and 2 show a flying boat having a hull formed with a main upper part a and a lower part or pontoon a<1>, part a having a water-tight upper surface. Pontoon a<1> is carried on fore and aft parallel links e, e<1> which permit the pontoon to swing downwardly and forwardly when lowered for alighting or take-off. The fore links e are made longer than links e<1> so that equal angular movement of the links causes the nose of the pontoon to tilt downwardly, the links being permitted a limited sliding movement relative either to hull or pontoon. Raising and lowering of pontoon a<1> is effected by four hydraulic means comprising piston rods f working in cylinders f<1> oscillatably mounted at f<2>. The aft hydraulic pistons are smaller than the forward pair. Stabilizing floats c, c<1> are each carried by two pairs of parallel links adapted to swing laterally toward and away from engine nacelles d<2> in which the floats are nested during flight. The links are actuated by two sets of cables anchored at one end to fixed brackets and passing over pulleys on hydraulic jacks h, i respectively, Fig. 3, retracting cables being associated with jack i and winding-out cables with jack h. The arrangement is such that winding in of one pair of cables is accompanied by equal paying out of the other set. Jacks h, i are supplied with pressure fluid through a control valve j<2> from the means operating the pontoon'jacks. This comprises an electrically driven pump g<3> which circulates fluid through a closed system comprising conduits g, g<1> connected above and below pistons of cylinders f<1>, a reversing and cut-off valve g<5> and a reservoir g<2>. Position indicating devices k<1>, g<10> are provided for floats and pontoon respectively. The upper deck of the pontoon may be provided with manholes to permit access from the main hull and may be used for occupation or storage.

Filed: 1917-04-04
Abstract: 117,095. Malcolmson, N., and Fitzgerald, F. W. V. April 4, 1917. Inorganic colouring-matters, dycing with. - Wool is dyed brown to black shades by means of a lead compound (oxide, carbonate, nitrate, acetate, sulphate, &c.) and caustic soda or calcium hydroxide or a mixture of sodium carbonate and lime. The shades may be varied by treating the goods with sulphuric or nitric acid; sodium or ammonium chloride may be added to the dyebath. A preparation containing lead and copper or iron salts is made by dehydrating a salt of copper or iron containing water of crystallization and then replacing the lost water by a saturated solution of a lead salt; these preparations are used in conjunction with sodium carbonate and lime for dyeing wool. Greyish-black shades on cotton are produced by means of the above-described preparations in conjunction with sulphur; the lead or lead and iron or copper compounds may be mechanically mixed with the sulphur and alkali, or the sulphur may be dissolved in heated paraffin and the lead salt be then added. The Provisional Specification refers also to the use in dyeing wool &c. of compounds of silver, zinc, cadmium, mercury, copper, aluminium, tin, lead, arsenic, antimony, bismuth, chromium, manganese, iron, nickel, and cobalt, in conjunction with compounds of sodium, potassium, ammonium, barium, strontium, calcium, chlorine, and sulphur.

Title: Improvements in or relating to hydraulic braking systems

Filed: 1944-03-22
Abstract: 577,999. Brakes. BENDIX AVIATION CORPORATION. March 22, 1944, No. 5375. Convention date, March 22, 1943. [Class 103 (i)] Relates to braking-systems wherein the pressure fluid from a manually operated master cylinder controls a valve which regulates pneumatic energy supply to a booster which operates an auxiliary master cylinder connected to the brake cylinders. In the construction shown in Fig. 3, the system described in Specification No. 550,450 is modified by placing the check valve 72 between the plunger of the auxiliary master cylinder 28 and the brake cylinders instead of in the master cylinder. This permits. residual pressure to be maintained in the brake cylinders whilst the remainder of the system is at atmospheric pressure during brake release. This ensures that the power-assister will operate almost immediately the pressure in the master cylinder is raised above reservoir pressure, while pedal flutter caused by the lag between action and reaction is avoided. The same advantages are obtained in the system shown in Fig. 5; which is a modification of the double line system described in Specification 557,762. The reaction of the air pressure on the plunger 110 is prevented from being transmitted to the master cylinder 10 through the pipe 106, by the provision of the passage 118 leading from the space 108 to the space 116, the latter space being enlarged by the movement of the piston 92 almost immediately the pedal is operated. The enlarged space accommodates the displaced liquid, and a spring-pressed ball valve 120 prevents liquid displacement in the opposite direction.
