Abstract: 1,053,481. Standby supply systems. SYNCHRO DEVELOPMENTS (LONDON) Ltd. April 12, 1965 [Jan. 13, 1964], No. 1372/64. Heading H2H. A standby electric supply system comprises a load which is normally fed from an A.C. supply, two change-over relays being provided so that, should the A.C. supply fail, the load is fed from a storage battery by way of a D.C./ A.C. inverter. The system also includes means to charge the battery from the A.C. supply when the A.C. supply is connected to the load. If desired the two change-over relays may be controlled by a voltage sensing transistor circuit so that the battery/inverter supplies the load when the voltage of the A.C. supply falls below a predetermined value. The inverter comprises a number of transistors and the battery is charged over a transistor/thyristor circuit with means to reduce the charge when a predetermined charge has been received by the battery. Means are also included to safeguard the circuit components should the battery be wrongly connected to the system.

In a damped pneumatic spring of the kind in which a flexibly walled chamber communicates with another chamber by way of an aperture containing a damping valve, the valve is of the form shown. The valve element is a resilient disc 14 sandwiched between two washers 15, 16 of unequal diameter. The unequal diameters give the valve different characteristics in the two opposite directions of air flow. In Fig. 2 the apertures 3 are to secure the valve, e.g. by bolts, within the spring and the apparently closed end plate 5 in fact contains flow ports. Fig. 4 (not shown), depicts a pneumatic spring of the kind referred to above containing a slightly modified form of valve shown in Fig. 2.

A rotary fuel pump of the radially-sliding abutment kind comprising a plurality of radial vanes 1, Fig .1, slidable in slots in the housing 2 and loaded by springs 3 into sealing engagement with a ring 4 which is caused to precess by an eccentrically mounted cam 5 on a pump drive shaft 6 includes a valve 9, Fig.2, rotatable with the shaft to supply and discharge fuel to and from the pump. The valve 9 may be connected to the shaft 6 by a flexible coupling 18, as shown, or formed integral with the shaft. Ports 12 permit fuel in the pumping chambers to flow to behind the vanes to hydraulically balance them. Using a pump of the sliding abutment kind reduces abrasive wear from contaminated fuel on the pump parts. The vane tips are sited where centrifugal force is least and this force will also tend to remove the abrasive material from the rotating ring 4.

Abstract: 1,232,143. Valves. ALKON PRODUCTS CORP. 11 March, 1969 [1 April, 1968], No. 12758/69. Heading F2V. A valve body having a close fitting spool slidable in a bore is floatingly fixed to a valve base by securing means and resilient means disposed between the base and the body so as not to be distorted. In one embodiment bolts 26 extend with clearance through holes 14a, 15a, 16a in the body and are screwed into holes 13, 14, 15 in the base. The distance between shoulders 30 and 28 on each bolt is greater than the thickness of the body. Resilient seals (24) are disposed in recesses 25 of the body and bias the latter into abutment with the shoulders 28 on the bolts and at the same time seal the passage of fluid from supply, exhaust and work ports 22 to the passages 6 in the body leading to the spool bore. A cover 4 may be secured over the body by bolts 31 screwing into the heads of bolts 26. In another embodiment the cover is rigidly secured to the base and the seals (24) bias the body against the top of the cover. In a modification the passages 6 pass completely through the body and further seals (41) are clamped between the body and cover to seal the passage ends. The fluid pressures in the passages 6 acting on the body to distort it radially of the spool are thus balanced.

Abstract: 1,251,410. Feeding articles. CLYDE CORP. 13 Nov., 1969 [31 Dec., 1968], No. 55596/69. Heading B8S. Articles in hopper 14 are discharged therefrom by oscillation of the hopper about axis 16, so that when the hopper is in the higher position a track 18 in the hopper is aligned with external tracks 22 and it delivers the articles thereto. In order that the articles may be replenished, the hopper is provided with a flexible band 60 secured thereto the band being fed with articles contained in container 34. Container 34 is positioned in the higher position shown by means of cable 36 operated by drum 38, and is lowered into the lower position to receive more articles. Operation.-As hopper 14 oscillates about axis 16 articles are discharged therefrom and when these articles fall below a minimum a switch 124 is operated which energizes a vibrator 122 to discharge articles from container 34 over the shoot 42 and down flexible shoot 60 into hopper 14 as the latter is moving. Guide 26 on hopper 14 prevents overflow of articles during reciprocation. Operation of switch 124, Fig. 3.-Pressure plate 80, pivotally mounted within hopper 14 at 82, is limited in movement by pin 120 operating within opening 118 formed in plate 80 and the plate is pressed upwards by plunger 100 which carries head 113 at the lower end thereof. When the articles in hopper 14 fall below a minimum the weight of the articles on plate 80 is insufficient to depress plunger 100. Hence head 113 assumes a higher position which during the movement of the hopper engages a roller 130 to operate switch 124 to cause replacement of the articles.

In apparatus for measuring the electrical resistivity of an earth formation transversed by a borehole 12, a current Is is passed through the formation via oscillator 15, variable gain amplifier 16 and electrodes A, B on a device 10 suspended in the borehole, the electric potential Vm of the formation, in phase with the applied current, is measured at electrodes M, N, and the product of the in-phase current and potential VmIs is kept constant by adjusting the magnitude of the current via the gain of the amplifier 16 as determined by the feedback potential Vref-VmIs, which should be zero, the resistivity of the formation then being a function of the magnitude of the current and/or of the potential. As shown, the in-phase current and potential, as determined by phase-sensitive detectors 19, 22, are applied to a multiplying circuit 20, the product signal then passing to a subtraction device 23 which subtracts the product signal from a reference signal Vref. Alternatively, the circuit 20 may include logarithmic converters and an addition device. If the gain of the feedback system is low so that the gain factor becomes variable then the resistivity of the formation must be determined from the value of Vm and the value of Is. These values are transmitted to a ratio circuit whose output Vm/Is is applied to a recorder 44 which indicates the resistivity. The recorder is driven as a function of borehole depth, as shown. If the gain in the feedback system is high so that the gain factor constant then either the value of Vm or Is is used to determine the resistivity. Either signal is transmitted to a squaring circuit 49 whose output is applied to a potentiometer 50 which divides the quantity Vm<SP>2</SP> by Vref. which gives the resistivity or the quantity Is<SP>2</SP> by Vref. which gives the inverse of the resistivity. The circuitary 14a may be contained in device 10 or may be provided on the surface. The signals Vm, Is may be transmitted to the squaring circuit or the ratio circuit on the same transmission channel by utilizing separate frequencies for Vm and Is. A focused electrode arrangement could be used.
