Abstract: 1,203,268. Sequestered metal ions. HOOKER CHEMICAL CORP. 29 Nov., 1967 [29 Nov., 1966], No. 54407/67. Headings C1A and C1C. Metal ions in solution are sequestered using compounds of the formula wherein R is a C 1 -C 3  alkylene group and Z and Z<SP>1</SP> are OH, C 1 -C 3  alkyl or C 1 -C 3  alkanol groups. Such sequestrantsincludetris-(hydroxymethyl)phosphine oxide, bis-(hydroxymethyl) phosphinic acid and bis-(hydroxymethyl) phosphine oxide. Metal ions mentioned include those of Al, Cr, Cu, Pb, Ni, Sn and the rare earth metals. The sequestrants are especially useful for sequestration of Fe<SP>3+</SP> at pH values of 7-14. The compounds may also be used to stabilize H 2 O 2  solutions. Specification 941,495 referred to.

Title: Spray timer
IPC: F16K31/48
Filed: 1965-12-23
Abstract: 1,112,649. Valves. ROBERTSHAW CONTROLS CO. 23 Dec., 1965 [24 Dec., 1964], No. 54653/65. Heading F2V. [Also in Division F1] The timer and actuating device as illustrated and in Figs 1 and 2 and 4 to 9 (not shown) controls the discharge valve of a pressurized fluid container 12 by operating on a spray nozzle 22 connected with the valve. The device comprises a housing 36 mounted on the container so as to enclose the nozzle excepting for an opening 40 aligned with the nozzle outlet. A clock mechanism 60 in the housing drives a cam device 56 which through follower means 58 causes tilting of the nozzle to operate the valve. A selector disc 98 is settable against a pointer 148 to determine the duration of operation and is associated with a stop means 114 which is arranged to arrest the clock mechanism. The housing is assembled on the container by an interrupted resilient sleeve 42 of the housing engaging in a moulding 20 of the container. The cam device 56 comprises upper and lower cams 62, 64 on opposite sides of a disc, which are engaged by two spring follower arms 68, 70 connected round, and rotatable on, a post 74. As arm 68 is moved outwardly, arm 70 drops off the cam 64 and engages the nozzle 22 to open the valve. The selector disc 98 is geared to a frictionally mounted pinion 140 on the shaft of a spring motor 84. The teeth 100 of this disc are interrupted over an arc 102-104, Fig 5, corresponding to ON-OFF markings on the disc. Thus from an initial setting the disc is driven to a rest position corresponding to OFF. In this position a cam 112 rotatable with the disc has depressed, through a follower pin 120, a stop assembly 114 against a spring 118 which serves also to rotate the stop assembly. This rotation is permitted when a hold-out cam 130, forming part of the cam device 56, has released a follower arm 124, 126 on the stop assembly 114. On rotation of the stop assembly 114 in its depressed position, a wedge surface 132 thereon engages a balance 134 of the clock mechanism to arrest it. The clockwork is wound by a cap 92. An electric clock motor may replace the spring motor.

Abstract: 1418100 Valves K G V OHRN 26 Nov 1973 [29 Nov 1972] 54799/73 Heading F2V A safety cut-off valve, which closes if the pressure at the outlet 45 falls below a predetermined value, e.g. as a result of hose failure, comprises a double conical closure member 23 which co-operates with a seat 27 in a sleeve member 5 fitted within a body 1. Pressure at the outlet 45 acts on the piston member 33, loaded by a spring 39, to move it towards the inlet 11 so that a pin 57 connected to it contacts a projection 59 on the closure member 23 to open the valve. If pressure at the outlet falls below the predetermined level the piston 33 moves back to its rest position and inlet pressure closes the valve against the light loading of spring 61. The closure member has a small by-pass passage 29 so that when the system is first put under pressure fluid flowing through this passageway will equalize the pressures on the two faces of the closure member so that it will open under the influence of the loading spring 61. The chamber 47 formed between the end of the piston 33 and the sleeve 5 is vented to atmosphere by a passage 49 which opens into a circumferential groove 51 in which is located a soft breathing membrane 53 which prevents dirt and moisture from entering the chamber 47.

Filed: 1967-12-19
Abstract: 1,183,870. Aircraft indicators. MINISTER OF TECHNOLOGY. 12 Dec., 1968 [19 Dec., 1967], No. 57707/67. Heading B7W. [Also in Division H4] In a system for indicating to a ground observer that the undercarriage of an aircraft is down, means are provided in the aircraft for applying a characteristic signal to a radio signal transmitted from the aircraft only when the aircraft is airborne and all parts of its undercarriage are down and locked in position ready for landing. As described, the outputs of three undercarriage lock switches for the port, starboard and nosewheel legs, an airspeed indicator switch operated when the speed is above a predetermined value and an undercarriage stress switch which is closed when the aircraft is airborne are supplied to the respective inputs of an AND gate. The output of the AND gate triggers a 15KHz oscillator which modulates the aircraft radio transmitter when the transmit switch is operated. At the ground station receiver 21, Fig. 2, the 15KHz signal is selected at 22 and operates a relay unit 23 to light lamps 24, 25, 26. The output of the relay unit also operates a monostable device 27 having a period of one second which controls a multivibrator 28 producing three pulses per second which in turn controls a 600 Hz oscillator 29. The monostable responds only to the initial voltage change from unit 23 when a modulation tone is received so that each time the pilot operates his transmit switch and the 15KHz signal is transmitted, the multivibrator runs for three cycles and the oscillator 29 provides three bursts of 600Hz to the headset 30. The headset 30 is also supplied with the normal radio-telephone transmission from the receiver 21. Alternative arrangement.-The indication may be in the form of a digital signal applied to a transponder in the aircraft, the ground station including a decoder and the video signals being presented as a distinctive pattern on a radar screen or as an alpha numeric display.
