Title: Vented non-drip liquid dispensing device
Filed: 1959-05-12
Abstract: 901,867. Batteries. BEALL, R. W., and CHANDLER, L. H. May 12, 1959 [Aug. 5, 1958], No. 16213/59. Class 53. [Also in Group XVII] A liquid dispenser, e.g. for filling car batteries, comprises a member A having a ribbed outer portion R positioned on the neck B of a container by means of an adapter P and carrying slidably a tubular spout member D having a liquid outflow passage 20 and an air inflow passage 22, the member D being rigidly connected to a collar G whereby it is urged outwardly from the container by a spring J in order to cause an integral valve member M to seat against a washer L. On raising the valve M from its seat liquid may flow under gravity through a port 24 formed in the wall of the tubular member D; at the same time air may enter the container via the passage 22, a port 30 in the wall of the member D, and an annular space between a section 16a of the wall of the member D and a flange C formed on the member A. Only partial opening of the valve M also permits an inflow of air from a space H within the collar G via a port 56 in the flange C, but further movement of the valve M cuts-off this route due to the fact that a sealing ring 57 integral with the member D is moved past the port 56. Thereafter the obstruction of the lower end of passage 22 by the rising liquid, e.g. in a car battery as it is being topped up, creates a partial vacuum in the container B<SP>1</SP> and so stops the outflow of liquid from passage 20. An alternative adapter, Fig. 4 (not shown), permits the device to be snapped on to a container neck, Fig. 5 (not shown). In a modification, Fig. 6 (not shown), lugs on the outside of the tubular member D enable a ring to be locked round the member D for engaging a ledge within the filling opening of a car battery thereby automatically regulating the level at which the liquid outflow will be cut-off. The spout member may be of resilient material, Fig. 8 (not shown).

Title: Improvements in washing boilers and similar apparatus
IPC: D06F15/02
Filed: 1932-06-08
Abstract: 402,789. Washing-boilers. ELFVING, T. M., 82, Nordenskjoldsgatan, Stockholm. June 8, 1932, No. 16218. Convention date, June 10, 1931. [Class 64 (i).] A clothes-washer has a boiler 3 closed to the air and separated from a washing chamber 1 by a yielding partition 7 such as a rubber diaphragm, and the gas pressure of the boiler is intermittently and preferably automatically varied, e.g. by an intermittently operating condenser 12. The partition may consist of a sliding piston. Clothes are placed on or under a perforated domed lid 8 through which washing liquid passes on to the rubber diaphragm 7, the other side of which forms the boiler top. Water is supplied to the condenser coil 12 in the boiler periodically through a siphon 14 from a container 15 into which water trickles continuously through a choke 17. When the water level in the container 15 falls, the gas is turned off by a control 26 and a forked arm 39 connected to a water float, so as to prevent heating of the boiler during condensation. Alternatively, a rod 31 on the diaphragm 7 has projections 40 engaging a gas control arm 30 to turn the gas down when the diaphragm is raised, and up when it is lowered. When boiler pressure is excessive the supply to the gas burner 6 is regulated by a box 21 with a piston 22 which is moved in one direction by the pressure of the boiler transmitted through a pipe 24 against a spring to close the gas supply pipe 36. Byepasses 28, 32, 38 maintain the burner alight. A rubber sleeve or diaphragm may cover a hole in the boiler to allow escape of steam only when pressure is excessive. Specification 360,290 is referred to. The Specification as open to inspection under Sect. 91 comprises also a yielding diaphragm in the form of a liquid trap such as an oil trap. This subject-matter does not appear in the Specification as accepted.

Abstract: 457,788. Hot-water systems. ATKINSON, J., 11, Cleckheaton Road, Bradford. June 5, 1935, No. 16299. [Class 64 (i)] In a hot - water storage tank, the flow pipe 18 discharges at a fixed point about two-thirds the height of the normal water level, and a stationary service pipe 13 is fitted with a sliding extension 14 with inlets 16 supported by a float 15. The flow pipe may be perforated at a point 19 below the top of the pipe 13. A division plate 3 forms an upper compartment 5 for the cold water, and an exhaust pipe 12 with an enlargement 3a projects through the plate 3 to form an air trap in the hot-water compartment 4. A cold water pipe 7 enters a cup 10 forming an extension of the return pipe 9 ; a perforated plate 11 prevents cold and hot water mixing. In a modification, the plate 3 is dispensed with and the cold water is supplied directly to the bottom of the tank.

Patent GB-585891-A (GB)
Title: Improvements in full span flap and aileron control
IPC: B64C13/00
Filed: 1944-09-06
Abstract: 585,891. Controlling aircraft. YOUNGMAN, R. T. Sept. 6, 1944, No. 17016. [Class 4] The system of rods or cables operating,an aileron mounted on a retractable flap, comprises an intermediate lever pivotally mounted on a flap-supporting link and movable in the plane defined by the pivotal axes of the link, the attachments of the lever to the rods or cables being coincident with the pivotal axes of the link when the lever is centralized and permitting universal pivotal movement of the rods or cables relative to the lever. This arrangement ensures that the relative positions of the flap and aileron are substantially unaffected by the retraction or extension of the flap. In one form, Fig. 1, a single flap 13 extends from the wing tip to a point within the fuselage and is supported by links 14, 15 and 16, the lower ends of the links being pivoted to the flap, the upper ends of links 15 and 16 to the wing, and the upper end of link 14 to the fuselage. The flap is normally nested in a recess in the wing and is extended and retracted by hydraulic or other jacks 18, the rams 17 of which are connected to intermediate points on the links. The angular movement of the flap is controlled by a torque link 19. An aileron 21 is carried by the outboard portion of the flap, the adjacent portion of the wing being cut away to allow movement of the aileron in the retracted position of the flap, and is controlled by a rod or cable 22, an intermediate lever 23 and a rod or cable 24 passing through the pivot of the link 14. The cable 22 may be connected directly to the control column or through hydraulic, electric or other powered mechanism. In a modification, Fig. 4 (not shown), the portion of the flap inboard of the aileron carries an auxiliary nested flap adapted to be extended automatically by the movement of the link 14 to extend the'main flap. If, in the case of a multi-engined mid-wing monoplane, Fig. 5 (not shown), it is impracticable to mount the inboard flap-supporting link on the fuselage, the cable 22 is passed through the wing and the lever 23 is mounted on a crossmember connecting two similar links which replace the link 15 shown in Fig. 1. If the outer panels of the wing have a different angular setting to the inner panels, the flap 13 may be divided into two or more sections, and those sections not fitted with ailerons may be set at greater angles when extended to give increased lift. If the wing tip chord is insufficient to accommodate a full span flap, wing tip ailerons may be provided which may be,operated together with, or independently of, the ailerons on the flaps. In the latter case, the flap aileron control mechanism may be disconnected for manoeuvring at high speeds, and brought into use only when the flap is extended. According to the Provisional Specification, extension of the flap may effect lowering of the aileron.

Title: Common-Controlled Automatic Telephone Exchange System
IPC: H04Q3/00
Filed: 1967-04-13
Abstract: 1,186,085. Automatic exchange systems. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP., FUJITSU Ltd., OKI ELECTRIC INDUSTRY CO. Ltd., NIPPON ELECTRIC CO. Ltd., and HITACHI Ltd. 13 April, 1967 [14 April, 1966], No. 17040/67. Heading H4K. In a cross-bar exchange employing a line link frame 25 and a trunk link frame 26, both comprising primary and secondary switches and controlled by a common marker 4, a number of overflow trunks 14 is provided so that in the event of an incoming call in the trunk link frame meeting congestion of direct paths to a subscriber 11 on the line link frame a path may be set up from the incoming junction to the appearance of an overflow trunk on the line link frame and from that trunk's appearance on the trunk link frame to the wanted subscriber 11. The overflow trunk appearances are distributed over the switches with the line and trunk appearances. The marker attempts an overflow connection by seizing an overflow trunk 14 and looking for a free path between the wanted subscriber 11 and the overflow trunk's appearance on the trunk link frame. If no such free path is found the marker seizes another overflow trunk and repeats the operation until a path is found or all free overflow trunks have been tried to no avail. Having established a path between the overflow trunk and a subscriber a search is made for a free path between the incoming junction and the appearance of the overflow trunk on the line link frame. If no free path of this sort exists attempts to establish the call are abandoned without examining the conditions existing with further available overflow trunks. The network is such that each of the links from a primary switch serving a subscriber give access to a secondary switch of the line frame. Similarly each of the links to a secondary switch serving an incoming junction provides access from a primary switch of the trunk frame. Between any one secondary switch of the line frame and any one primary switch of the trunk frame, however, a set of four links are available and provide a first, second, third and fourth choice for the marker in path finding. The path finding process, in consequence, couples sets of three test leads each set comprising a test lead from a first choice inter-frame link and one test lead from each of the line and trunk frame links giving access to the first choice link. Each such set of test leads has a common test relay so that should any one of the links be busy the relay operates to mark the path defined by the set of three links busy. A relay chain selects the first unenergized one of the test relays according to their position in the chain and a free path so nominated by the marker is employed to establish a connection. If the relay chain finds no unenergized test relay it advances testing to the second choice inter-frame links and so on through to the fourth choice links and to the overflow trunks if necessary.

Title: Shock absorbers
IPC: B60G13/04
Filed: 1944-09-06
Abstract: 587,287. Shock-absorbers. STEVENS, A. H. (Thompson Products, Inc.). Sept. 6, 1944, No. 17044. [Class 108 (iii)] In a shock-absorber, an expansible unit 12 movable axially within a casing or cylinder 11 by an actuating rod 15, has an adjustable connection with the rod located wholly within the unit, relative rotation of the rod and casing altering the compression of a spring 30 so as to vary the frictional co - operation be - tween the unit and casing. The unit comprises an expansible sleeve 20 engaged by a pair of tapered expanders 23, 24, the spring being located between one expander 23 and a shoulder 27 on the actuating rod while a nut 32 threaded on a portion 28 of the rod engages the other expander 24 and is held against rotation so that relative rotation of the rod and casing moves the nut axially to vary the compression of the spring. The expansible sleeve 20 consists of segments with tapered faces 21, 22 engageable by the expanders 23, 24 which are tapered and of non-circular contour, a spring ring 24<1> normally urging the sleeve out of engagement with the cylinder 11. The expanders 23, 24 are formed with recesses 29, 31 containing respectively the spring 30 and nut 32, the spring 30, which bears on a washer 33, urging the expanders towards each other to produce an initial expansion of the sleeve 20 against the cylinder 11. On relative movement of the rod and cylinder one or other of the expanders causes further expansion of the sleeve 20 and thus an increased frictional drag on the cylinder. To enable adjustment of the device to be effected, the nut 32 is prevented from turning by engaging a similarly-shaped non-circular recess 31 or by a rib 35 on the nut engaging a slot 36 in the expander 34, which, being of non-circular contour, is also held against turning by the friction sleeve 20 in engagement with the cylinder 11. To prevent. undesirable rotation of the rod 15, e.g., when the shock-absorber is being transported, an axial rib 38 on a guard 18 secured to the rod, co-operates with projections 39 on the cylinder and, prior to adjustment, the rod and cylinder are relatively extended to disengage the rib from the projections. A compression spring 41 in the closed end of the cylinder prevents " bottoming " of the expansible unit and carries a cup 44 for engaging the expander 24 to further expand the friction sleeve. The cylinder may contain a quantity of loose dry lubricating powder 45 adapted to be introduced into or withdrawn from the cylinder by suction &c. through an opening 46.
