Title: Improvements relating to electrical signalling apparatus
IPC: B63H25/00
Filed: 1941-08-26
Abstract: 551,189. Electric signalling. PULLIN & CO., Ltd., R. B., and SLINN, W. H. Aug. 26, 1941, No. 10886. [Classes 40 (i) and 118 (ii)] A device for signalling to a helmsman prearranged changes of course comprises a clockdriven disc in which pins of various lengths (which may be built up from two lengths) are inserted in holes in two concentric tracks. As each pin reaches a pre-determined position, a series of impulses is sent to one of two magnets for stepping an indicator in opposite directions according as the pin is in one or other of the tracks. The length of the series depends on the length of the pin. The indicator thus shows the direction and extent of the required alteration of course. Means are provided for bringing the indicator to normal automatically once in every rotation of the pin disc or at will. Means are provided for stepping the disc in either direction under clock control and also for making either track of pins control either direction of course alteration. The disc is readily detachable. Details.-Clock-controlled contacts 10 energize a relay 30 for ten seconds every minute and this energizes a magnet 34 or 34a, according to the position of a switch 18, to step round a commutator 59 which controls a resultantfield motor geared to the pin disc. When a pin reaches the operative position, it tilts one of a pair of lever 85, 86, Figs. 12 and 13. Both levers operate contacts 90 but lever 85 also operates switch 110 to connect up the stepping magnet 102a instead of 102 of the indicator with switch 109 in the position shown (or 102 instead of 102a with the switch in the other position). On the closure of contact 90 a circuit is made for relay 94 which thereupon interacts with relay 114. Impulses are thus sent to one of the indicator magnets. At the same time, relay 94 itself steps a feeler member 138, Fig. 16, until it engages the end of the operative pin, whereupon further operation of 94 is prevented and impulsing ceases. The feeler is held in its displaced position by a magnet 113 until the pin moves on. At the end of a signalling cycle, a member on the pin disc changes over contacts 82 to energize a relay 174 which can also be operated at will by means of a key 28. This disconnects the normal circuits of the indicator magnets and substitutes one via a gapped ring 165, 166 driven with the indicator. At the same time, a circuit is made for 94 which interacts with 114 to send impulses to drive the indicator to its zero position. In this position, the wiper 164 is in the gap in the ring and the indicator stops, but 94 continues to generate impulses idly until a flange 138a on the feeler engages a stop 138b. When the key 28 is released or the pin disc moves on, magnet 113 releases the feeler. A bell signal is given to the helmsman when the indicator is about to be driven and various tell-tale lamps are provided to indicate the condition of the apparatus.

Title: Valve
IPC: A61M16/20
Filed: 1978-03-20
Abstract: The pressure relief (limiting) valve contains a valve chamber which is connected via an inlet opening (32) to the respirator and via an outlet opening to the atmosphere and has a valve closing member which lifts off from its valve seat (39) at the inlet opening at a certain pressure and thus connects the respirator to the atmosphere. The valve closing member is a valve diaphragm (23) which in the valve chamber (36) partitions off a closing-pressure chamber (37) supplied via a restrictor (24) with an auxiliary gas stream. Its top wall (40) contains a control valve (21, 22) leading to an outlet chamber (42) open via an opening (41) to the atmosphere. The tappet (43) of the axially movable control-valve cone (21), said tappet being passed through the said chamber, extends as far as a control diaphragm (20) which closes off a control chamber (38), arranged above the latter, which is subjected via a line (19) to the pressure of the breathing gas. It is thereby possible in the inhalation phase to discharge even large quantities of the breathing gas which remain unconsumed by the patient, and to do this virtually without an increase in pressure. <IMAGE>

Abstract: 326,062. Filing Equipment Bureau, Inc., and Charlton, R. H. April 13, 1929. Partitioned boxes. -In filing-drawers or trays of the kind wherein longitudinally arranged guides support a transverse panel or panels which divide the drawer space into compartments, panel supporting members movably mounted on the guides are associated with spring members which normally restrain the movement of the panels. The guides are preferably in the form of a pair of vertically spaced rails 13, Figs. 2 and 3, mounted above each side wall 10 of the drawer, with their front and rear ends respectively fitting within sleeves 16, 17 in rail supports 14, 15. The rail supports 14 each comprise a pair of metal plates secured together by rivets 26 and slightly spread apart at their front ends to provide resilient gripping jaws which engage vertical fin-like plates 9 on the front of the drawer, the outer plates being shaped to form the sleeves 16 and bent at their lower edges to form flanges 18 which rest upon the rolled-over upper edges 11 of the drawer. The outer plates of the rear support 15 are shaped to form the sleeves 17 and flanged edge-rests 19, the inner plates 33 being extended downwardly and turned at their rear edges to form sleeves 34, Fig. 3, which receive the limbs of a resilient U-shaped expander rod 35 serving to hold the plates 33 against the walls of the drawer and retain the rail supports 15 in position. The panel-supporting members or slides 20 are formed with sleeves 21 to engage the guide rods 13 and are preferably provided between the sleeves with spaced vertical slots 22 to receive end wings on the transverse panels 28 within the drawer. Helical springs 25 on one of each pair of guide rods are disposed between the panels 23 to restrain their sliding movement, the ends of the springs preferably being secured within collars 38 which abut against the slides 20 and may be moved independently of the slides. The panels 23 may be made of metal, wood, or other material and are preferably reinforced at the upper edges by metal strips which project laterally of the panels and provide the end wings engaging the slots 22 in the supports. The end wings are offset in opposite directions, thereby enabling them to be detached from their slots by moving one of their supports 20 relatively to the other. The apparatus may be attached to a drawer which is not provided with the fins 9 to engage the front ends of the rail supports 14, these latter then being formed similarly to the rear members 15, with tubular sockets to receive the upwardly extending limbs of a resilient U-shaped member acting similarly to the member 35.

Title: Improvements relating to fluid pressure braking apparatus for aircraft landing wheels
IPC: B64C25/46
Filed: 1953-04-27
Abstract: 725,207. Fluid pressure brakes. WESTING- HOUSE AIR BRAKE CO. April 27, 1953 [May 24, 1952], No. 11578/53. Class 103 (1). A control valve assembly for aircraft braking systems comprises two co-operating valve spindles 23 and 24 of which the former is actuated to prevent the brakes being applied when the wheels are retracted in flight and the latter is actuated by a wheel slip detection device of the kind described in Specification 674,506 whereby the brake cylinder pressure is governed in such a way as to prevent wheel locking. As shown in Fig. 1, the undercarriage is diagrammatically represented as being operated by fluid pressure supplied on each side of a piston under the control of a threeposition control valve 11. To retract the undercarriage the valve would be turned to the position 17 in which pipe 18, from which are branch leads to the lower side of the piston, would be in communication with hydraulic supply line 13. The pipe 18 also leads to a chamber 34 at the top of valve spindle 23 and the pressure acting thereon causes it to move downwardly until its end engages the fork member 31, the spring loaded ball 35 leaving the groove 37 and entering the groove 36. In this condition the brake cylinder 3 is vented to atmosphere through pipe 82, passage 51, chamber 50, ports 48, passage 44, chamber 42, ports 45 and passageway 39. Ports 41, to which pressure is supplied from a reservoir 8 through a control valve 7 and pipe 4 are simultaneously blocked off. When the airplane wheels make contact with the ground, the wheel slip detector 6 operates shaft 10 and levers 29 and 31, so as to move both valves 23 and 24 upwardly. The valve 23 is then locked with ball 35 in groove 37 and in this condition pressure from the line 4 is passed by ports 41 and chamber 42 to ports 43, passage 44 and to ports 48 around the valve member 24. The valve member 24 is raised or lowered by the slip detector as necessary to regulate the brake cylinder pressure to avoid skidding, the brake cylinder being connected to atmosphere through ports 47, 46 and passageway 39 when the valve is raised and to the supply line through ports 48, 47, passageway 51 and pipe 82 when it falls.

Title: Polymers containing silicon, aluminium and phosphorus
Inventor: BAMFORD WILLIAM RANDALL
IPC: C08G77/58
Filed: 1961-04-06
Abstract: Polymers, in which the chains are made up of recurring groups containing Si, O and Al atoms, with P in substituent groups, are made by reacting together a diacyloxy silicon compound and a diorganophosphinoxyaluminium dialkoxide.  The organosilicon reactant may be a diorganodiacyloxysilane, a bis-(acyloxydiorganosilyl)benzene, -diphenyl or -diphenyl ether, or a 1,3-diacyloxydisiloxane, in which the Sibonded radicals, other than acyloxy, are lower alkyl, alkenyl or aryl radicals. The other reactant may be made by reacting a diorganophosphinic acid with an aluminium alkoxide (see Group IV(b) ), usually in the presence of an inert solvent, and may be used per se or after separation and purification.  The polymerforming reaction may be effected in an inert solvent and in the presence of a catalyst, e.g. dibutyltin oxide, dibutyltin dilaurate and ferric chloride. In typical examples (1) the purified reaction product of aluminium isopropoxide and dimethylphosphinic acid was dissolved in benzene and refluxed with dimethyldiacetoxy silane to yield, after removal of solvent, a white powder which, on mixing with asbestos fibre, yielded a heat resistant thermoset product; (8) dimethylphosphinoxyaluminium diisopropoxide was reacted with 4,41-bis-(acetoxydimethylsilyl)diphenyl to yield a white powder which was capable of being drawn into fibres.ALSO:Diorganophosphinoxyaluminium dialkoxides may be made by reacting, in equimolecular proportions, a diorganophosphinic acid, in which the organo groups are lower alkyl groups, e.g. methyl, ethyl, propyl or butyl, or aryl groups such as phenyl, with an aluminium alkoxide, in which the alkoxy groups are ethoxy, n-propoxy, isopropoxy or n-, iso- or sec.-butoxy groups, and removing the alcohol formed from the reaction mixture.  Usually the reaction is effected in a suitable solvent, preferably one which will form an azeotrope with the alcohol formed in the reaction.  If desired, the product may be purified by sublimation under vacuum.  In Example (1) aluminium isopropoxide, dimethylphosphinic acid and dry benzene were heated under reflux, after which the solvent was distilled off to yield a residue which, on purification by sublimation, yielded a white solid, M.P. 95 DEG C., of dimethylphosphinoxyaluminium diisopropoxide.
