Title: Improvements in electric switches
IPC: H01H19/56
Filed: 1924-11-03

Patent GB-867159-A (GB)
Title: Tank gauging system
IPC: G01F23/00
Filed: 1959-07-30
Abstract: 867,159. Indicating liquid levels. VAPOR RECOVERY SYSTEMS CO. July 30, 1959 [May 21, 1959], No. 26165/59. Class 123(1) A liquid level indicator consists of a flat solid plate 12 of a material denser than the liquid L which is suspended so as to be partially submerged in the liquid by a uniformly perforated steel tape 14 which passes over idler sheaves 18, 20, around a sprocket sheave 22 carried on the shaft 62 of a revolution counter 10 and has its end fastened to a storage sheave 16. The idler sheave 18 is mounted on a torque arm 26 pivoted at 28, the tendency of the arm to be rotated in a clockwise direction by the weight of the tape 14 and plate 12 being resisted by a torque tube assembly 32. This assembly consists of an outer tube 34 and an inner rod 36 both secured at one end to the torque arm at the pivotal axis thereof. The other end of the tube 34 is secured in a stationary housing 44 whilst the other end of the rod 36 carries a switch arm 50 which co-operates with a fixed switch arm 52. The switch 50, 52 is connected in a circuit including a relay coil 92, the period of operation of which is determined by a resistance 96 and condenser 98, and a reversible A.C. motor 70 which drives the storage sheave 16 through a gear train 72, 74, 76. In operation, the contacts 50, 52 remain closed sufficiently long to operate the relay, when the motor drives the sheave to lift the plate 12 a small amount. The liquid then exerts a lesser bouyancy on the plate and the arm 26 turns downwardly. The contacts 50, 52 open and the relay is de-energised causing the motor to reverse its direction and lower the plate more into the liquid. When the arm 26 is relieved of the weight of the plate the contacts are again closed to repeat the cycle. The system thus continuously hunts about a null point representing the true level and an average of the " up " and " down " readings on the gauge 10 gives the true level reading. Observation of the continuous oscillation of the gauge confirms that the system is operating properly.

Filed: 1953-09-28
Abstract: 744,870. Filters; purifying liquids. CRUICKSHANK, Ltd., R. Aug. 3, 1954 [Sept. 28, 1953], No. 26567/53. Class 46. Liquid purifying and filtering apparatus comprises the combination of a hollow vertical body having an entrance at its lower end, a removable perforated container for granular activated charcoal or other purifying and filtering material in the lower end of the body, a discharge chamber at the upper end of the body, and means for suspending one or more filtering bags of textile material in an intermediate region of the body. Liquid entering a steel cylinder 3 at 4 passes first into a shallow inlet chamber 23 and then through granular activated charcoal or the like contained in a removable cylindrical box 5. A bolt 6 engaging a tapped boss 7 in the base of the cylinder serves to hold in position the box and a removable perforated top 8 and bottom 9, and to clamp between flanges on the box and the top 8 and bottom 9, respectively, discs 10 of gauze. Thereafter the liquid passes inwards through textile filter bags 13, each supported internally by a helically coiled wire 14, and thence through tubular members 12 by which the bags are suspended from a plate 11. The filtrate passes into the dished portion of a removable cover 15, forming an effluent chamber, and thence through outlet connections 16. The cylinder 3 may be mounted on legs on a base carrying a circulating pump and driving motor.

Title: Surgical dilator
IPC: A61M29/00
Filed: 1919-10-30
Abstract: 146,026. Pegaitaz, H. Oct. 30, 1919. Dilating-instruments.- A dilator comprises a number of prisms grouped about a central rod and connected at one end by links to the rod and at the other end to a member sliding thereon. In the form shown, sixteen prisms b are grouped about a central rod a and are provided at each end with pivot members c connected by links d to a cap e fixed to the rod a and to a sliding member f respectively. The member f is hollow and encloses a spring f<1> and a plate g fixed to the rod a, and is screw-threaded internally to engage a nut h. On unscrewing the nut h to the position shown in Fig. 3, the spring f<1> forces the sliding member f upwards, so that, the prisms b are moved radially away from the central rod. The prisms are connected in pairs by slotted links l engaging pins i, so that on dilation, they are turned about the pivot members c to the position shown in the upper part of Fig. 1. In alternative methods of operation, the nut h is removed and the rod a engaged directly by a ring k, or by a Bowden wire, the sheath of which is connected to the member f, or by a rod sliding within a rigid tube.

Abstract: 600,295. Safety razors. HEIDE, H. C. (Gillette Safety Razor Co.). Oct. 12, 1945, No. 26767. [Class 30] [Also in Group XVII] In a safety razor of the kind having a cap and guard which, when unclamped, provide a passage through which a blade can be inserted, and a tubular handle housing a clamping spindle adapted to engage the cap to clamp the blade, the handle is apertured so that when the spindle is retracted within the handle to allow a blade to be inserted, a suitably shaped part of the spindle is exposed through the aperture in the handle to receive a member passed through the aperture to lock the spindle in retracted position. The guard 10, Fig. 1, having a blade locating rib 14 is secured to a tubular handle 12 housing a clamping spindle 20 which may be engaged with a threaded opening 19 in the cap 15 to clamp the blade or may be withdrawn as shown to provide a clear passage between the cap and guard for the entry of a blade. The cap 15 has downwardly extending arms 16 and a horizontal arm 17 engaging in a recess in the underside of the guard. In the retracted position of the spindle 20 a shoulder 23 therein is in alignment with slots 24, Fig. 2, in the handle through which a forked locking member 34 may be passed to engage the shoulder and hold the spindle in retracted position. The forked member may, as shown, be secured to a blade magazine of the construction described in Specification 572,579, [Group XVII], and thus also serve to locate the magazine in correct position. Specification 600,277 also is referred to.

Filed: 1961-07-25
Abstract: 919,470. Filters. BERLINE J. R. A. July 25, 1961 [July 27, 1960], No. 26925/61. Class 46. In a cluster of filtering tubes each tube 1 has a flared upper end supported by an annular rubber or plastic gasket 18 in a supporting plate 16 and is held under adjustable pressure from bolts 21 in washers 20 which, through tube retaining rings 19, exert pressure against a plurality of tubes simultaneously. Each tube consists of a core 2 of perforated sheet metal or expanded metal and a sheath 5 of metal or synethetic fabric e.g. " Terylene " Registered Trade Mark and is rigidly united with an endpiece 4 which is secured to a metal lattice 6 by a stud 8. For cleaning, filtrate accumulated in a dome of the filter housing is counterstreamed by the pressure of gas in the dome, or introduced thereto, and this with the help of the resultant vibration of the tubes, causes the filter cake on the outer face of the filter fabric to be removed. Alternatively, steam under pressure may be used to clean the tubes. The washers may be circular or star-shaped, each point of a star being assigned to a tube.

Title: Improvements in apparatus for controlling the flow of liquids to maintain a constantlevel
IPC: F22D5/08
Filed: 1927-10-15
Abstract: 302,756. Smith, W. Oct. 15, 1927. Valves controlled by pilot or relay valves.-In apparatus for controlling the flow of liquids to maintain a constant level in a vessel, such as a tank, boiler, &c., in which hydraulically supply valves are controlled by a pair of float-controlled relay valves, the connections between the float C and the valves A, B are, such that these valves are operated in succession. The float C is pivotally suspended at F' on a link F<2> depending from a bracket E<4> and the valves A, B are connected by links G, J to points F<4>, J<1> below and above the pivot F<1>, respectively. As the liquid level falls the float lowers on its fulcrum F<1> and closes the valve A thereby restricting the escape of operating fluid from one of the supply valve units and causing that supply valve to close and cut down half the total supply. On further lowering of the water level the fulcrum of the float is transferred to the pivot F' and the float closes the valve B and thereby the remaining supply valve unit. Instead of the pivoted link F<2>, the fulcrum of the float may be made an easy fit in its housing to provide for the same action.
