Abstract: 1,080,783. Valves. DANFOSS A.S. Aug. 7, 1964 [Aug. 27, 1963], No. 32234/64. Heading F2V. A thermoelectrically controlled safety valve for a gas burner is provided with supplementary mechanical closing means. Gas flows from chamber 26 through seat 23 to an ignition burner upon depression of a key 48 to displace a cap unit 36 and a spindle 35 against a spring 37 to unseat an ignition closure 32 and telescope a cup 28 within a cup 27, against a spring 29, to engage an electromagnet 33 with an armature 31; the key 48 is retained in the depressed position by a ratchet lever (54) (Fig. 1, not shown) until released by replacement by a key 49 which permits the spindle 35 and cup 28 assembly, retained together by actuation of the magnet 33 from the ignition burner, to return until halted by a stop 40 upon casing 15 in which position both ignition closure 32 and a closure 30, for the passage of gas via an outlet 17 to the main burner, are unseated. Upon depression of a key 47 into a retained position, key 49 is returned and an arm 57 dependent from key 47 engages the free end 45 of a lever 42 which is pivoted to push the cap unit 36 upwards so that the magnet 33 and armature 31 are separated to permit closures 32 and 30 to seat. The operating spindle 35 may also be controlled by the engagement of a lug at the upper end thereof within the groove of a rotated cam disc the radius thereof varying according to the three desired positions of the valve with a radial cam path permitting the safety function of the valve in the operating position. The valves may also be operated by cable connection between the spindle and the keys. In another embodiment, a single gas safety valve is displaced from a seat by a spindle and retained in the open position by a thermally actuated magnet until displaced therefrom by a spindle manually actuated in the opposite direction.

Abstract: 1,229,637. Aerials. BECKER FLUGFUNKWERK G.m.b.H. 10 Dec., 1968, No. 58707/68. Heading H4A. A life-jacket consists of a collar-shaped inflatable tube 1 which when deflated is enclosed by a covering 2, having pressure studs 3 for closure, and belts 4 for attachment to the body of a user. On one arm 5 of the tube 1 is carried a cartridge 6<SP>1</SP> of compressed air, for automatic inflation in case of need. A bag-shaped piece of material 7, which is slipped over the other arm 6 of the tube 1, has a metal plate 8 on its upper surface, to which a flexible rod aerial 10 is connected by means of a collar 12 and a pivot 9. The rod 10 is stowed around the tube 1 when deflated, but upon inflation said rod assumes an erect position by reason of forces exerted by resilient stays 11 which are connected between the bag-shaped piece 7 and the collar 12, and by reason of its own resilience. The invention may be applied to other inflatable emergency lifesaving devices, such as life-buoys or dinghies.

In a carburetter having a suction actuated air valve 18, Fig.1, and a throttle valve 15, a conduit 35 provides a connection between the suction chamber 22 and the inlet manifold a valve 43 normally closing the conduit is opened directly by or as a result of conditions arising from the closure of the throttle valve. An arm 39 attached to the throttle shaft 41 closes a switch 38 to energize a solenoid 37 to open valve 43 when the throttle valve 3 is closed. In another embodiment the valve 43 is replaced by a spring closed valve (48), Fig. 2 (not shown) attached to a diaphragm (49) which is acted on by the inlet vacuum. In a modification of the latter embodiment valve (48) is replaced by a valve (55) Fig.3 (not shown) which when opened allows the conduit 35 to communicate with the inlet manifold through the space above the diaphragm (49) which acts on valve (55).

Abstract: 1,258,709. Anti-skid control systems. KELSEY HAYES CO. 21 April, 1970 [5 May, 1969], No. 19115/70. Heading F2F. An hydraulic vehicular braking system includes a vacuum assisted power brake unit 12, a skid control system 14 including a modulating valve assembly 58 and a control module 50 for producing a control signal in response to the presence of a skid condition and an auxiliary control valve 10 responsive to the control signal for controlling actuation of the power brake unit 12. As shown, the power brake unit 12 comprises two motor chambers 18, 20 on respective sides of a diaphragm member 22 both of which chambers 18, 20 are normally connected to a vacuum source but on actuation of the power brake unit 12 by brake pedal 38 chamber 18 is connected to ambient air via a passage 26, a chamber 28, an air conduit 30 and the control valve 10: the pressure differential thereby set up across member 22 causes movement of a piston 40 to actuate a master cylinder 44. The auxiliary control valve 10 includes a solenoid assembly 118 actuable on receipt of the control signal from the control module 50 to cause air flow across the valve 10 to air conduit 30 to be stopped to thereby prevent an increase in booster force provided by unit 12. The valve 10 includes a valve member 104 one side of which is normally connected to the vacuum source via a line 83 and the other side of which is connected to ambient air via an inlet 68 and filter 140, the ambient air then flowing out of the valve-10 to the conduit 30 via an outlet 72. On actuation of the solenoid windings 126 'of the assembly 118 a plunger member 128 is moved to the left against the action of a coil spring 146 and a valve section 142 of the member 128 is brought into contact with a face 84 to block communication with the vacuum line 83. Ambient air then flows into the left side of the member 104 via an opening 106 and a spring 150 becomes effective to move the member 104 to the right against an annular valve seat 114 to thereby block air flow across the valve 10. On a termination of the control signal the components of the valve 10 return to their positions shown in the drawing, with however, a time delay which delay is given by the provision of an orifice 86 which slows down the reattainment of a vacuum condition on the left side of the valve member 104.

The position of the float is a measure of the density, and is determined by the buoyancy of the float 20, the magnetic interaction between the two magnets 15 and 12, and the weights of the float. The position of the float may be determined by measuring the rate of change of the magnetic field as the float moves, or by the rate of change of a capacitance with which the float forms one electrode, by means of a Hall probe, or by detecting the change in rate of heating when the float closes an orifice through which convention currents pass. In alternative embodiments two fixed magnets may be provided with the movable magnet between them, or the fixed magnets may be positioned above the float. The guide member may take the form of a hollow tube containing the float, or alternatively the guide member may comprise a rod passing through a hole in the centre of the float.
