Title: Improvements relating to feed-water regulators for steam generators
Inventor: GARDAM HARRY EDWARD
IPC: F22B35/00
Filed: 1958-09-25
Abstract: 875,121. Feedwater regulators. STONE & CO. (DEPTFORD) Ltd., J. Sept. 1, 1959 [Sept. 25, 1958], No. 30743/58. Class 123(2) A forced-flow boiler comprising concentric groups of tube coils 12, 15 surrounding a heating chamber 16 which is downwardly fired by a burner 18 is supplied with feedwater by a pump 21 through a conduit 23. a water flow-responsive fuel control mechanism 24 as described in Specification 724,424, a non-return valve 26 and conduit 25, steam-water mixture leaving the boiler through a conduit 27 to enter a separator 28 whence steam is drawn off at 30 and separated water returns to the feed reservoir 20 through a conduit 29. The pump 21 supplies water at a constant rate, only the amount required for evaporation flow ing through the conduit 23 whilst the remainder is diverted through a conduit 35, regulator 34 and conduit 36 to the reservoir 20. The regulator is shown in Fig. 2. It has an upper pressure chamber 33 connected by a conduit 32 to the separator steam outlet 30, the steam pressure being exerted on a diaphragm 109 to which is attached a plunger 110. A valve operating rod 112 is adjustably screwed into the plunger which carries a collar 116 against which bear springs 114, the springs tending to balance the downward thrust of the steam pressure. In the lower part of the regulator is housed an upwardly tapering valve' 37 which is carried on a stem 104 slidably guided by bushes 105 and terminating adjacent the lower end of the rod 112. The valve which opens downwardly is held closed by a light spring 107. The chamber 117 above the valve which is connected to the conduit 35 from the feed pump outlet is also connected by a conduit 118 to a chamber 119 below a flexible diaphragm 120 carrying a centre button 123 into which is adjustably screwed the lower end of the valve stem 104. The chamber between the diaphragm 120 and the valve is connected by the conduit 36 to the reservoir 20. At a particular load the forces acting on the valve are in balance and the appropriate proportion of the pump output is by-passed to the reservoir. If the load decreases, the momentary increase in steam pressure on the diaphragm 120 will decrease thus compensating for the increased pressure of the springs 114, with the result that the steam pressure at the new load will be the same. as at the original lead. An increased demand for steam will have the converse effect.

IPC: B60G99/00
Filed: 1949-11-24
Abstract: 662,538. Vehicle frames, engine mountings. MORRIS MOTORS Ltd. Nov. 24, 1949. No. 30842/48. Classes 79(iii) and 79(iv) Also in Group XXXII] In a motor vehicle of the type having a combined body and underframe and in which the wheel suspension means are attached to a sub-frame on which the engine and the end of the vehicle body are separately mounted resiliently, the body is attached to the sub-frame by resilient mountings which are spaced apart longitudinally, the mounting means carrying the major load being fixed to a bridgelike structure and located substantially in the same horizontal plane as the centre of gravity of the vehicle body, to minimize body roll relative to the sub-frame. As shown, the power unit and the front wheel suspension are mounted on a triangular underframe G which is resiliently connected to the combined body and frame B. The underframe has a front transverse member D3 and corner bracing members D7, D8 The front end of the power unit is mounted on the bracing members, with the interposition of inclined rubber blocks E1, E2. The rear end of the power unit is supported by a rubber block E3 on the transverse member D9. The wheels are independently suspended by parallel links and sprung by torsion springs. Each wheel is carried by a lower articulated link C3 whose inner end is fast with one end of a torsion bar C1 or C2, and an upper link C4 constituted by the arm of a shock absorber C5 which is secured to the bridgelike cross member G. The bars C1 and C2 are secured to the ends of an underthe floor of the body being reinforced adjacent such mountings with a channel member U, and by a pair of resilient mountings F1, F2 which connect the bridge-piece G of the underframe with dashboard N and toe board M. The two resilient mountings F1, F2, which may be replaced by a single centrally disposed mounting, are disposed at approximately the same height as the centre of gravity of the body. Since the power rear ends of the torsion unit is separated from the frame cross member D4. The underframe is secured to the body by a pair of resilient mountings F3, F4, body by two lots of resilient mountings, the mountings E1-E3 between the power unit and underframe may be made stiffer than usual, with the result that the mass of the power unit contributes materially towards damping the vibrations induced by the wheels in the underframe before they are passed on to the body via the mountings F1-F4.

Title: Digital delay circuit
IPC: H03K3/45
Filed: 1966-07-14
Abstract: 1,127,986. Pulse delay circuits; circuits employing saturable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORP. 14 July, 1966 [13 Aug., 1965], No. 31583/66. Headings H3B and H3T. In a digital delay circuit in which an input digit pulse is applied directly to an AND gate 17 to enable the gate, and indirectly to the AND gate via a delay network to inhibit the gate during a delay period, the delay period is determined by the switching time of a transformer 12 having a substantially square loop core. As shown, when a positive input is applied at A, transistor 2 conducts and drives the state of the transformer core from a negative saturation, to which it is normally biased by a winding 13, to a positive saturation. During this change of state a negative pulse is produced at B for the delay period to inhibit the AND gate 17 and maintain the inverter transistor 21 OFF. When the transformer core reaches its positive saturation state the potential at point B rises to the value at terminal 10 and together with the positive potential applied to diode 18 from the input A enables the AND gate which causes the inverter transistor 21 to turn ON. The output D from the inverter transistor can be converted into a positive value by including a further inverter circuit 26 connected to the output D. The transformer 12 can have a tape wound core or a ferrite core and can have tappings 40-42 to enable different time delays to be selected.
