Title: Improvements relating to Non-refillable Bottles.
Inventor: SILVERTHORNE FRANK HODGKINS
IPC: B65D49/06
Filed: 1917-11-05
Abstract: 119,323. Silverthorne, F. H. Nov. 5, 1917. Bottles, non-refillable.-In a closure for a non-refillable bottle in which separate air and liquid passages are provided, the seat for the air valve is adapted to contain and hold the valve when the latter is forced into the seat on an attempt to refill the bottle. The attachment 10, Fig. 1, is secured on a gasket 12 on the top of the neck of the bottle 6 by a ferrule 9 engaging under the bead 7. The flat circular member 15, forming the bottom of the body 10, is fitted in a recessed part 14 at the base of the body and has a lug to engage a notch in the part 14. The upper part of the attachment is inclined laterally to indicate the pouring position and is bevelled off at the top. The straight liquid passage 23 terminates above the wall 25 forming the bottom of a pocket 21 and has its end bevelled off. The tortuous air-inlet 27 is enlarged at the lower end to form a chamber 28 for a spherical valve 29 which seats upon a cork seat 30, a bevelled lug 31 limiting the upward movement of the valve. Any liquid spilt in the pocket 21 is directed by the inclined wall 25 back into the inlet 27. An annular groove 37 is formed in the upper face of the seat 15 of the cork disk valve 36 which controls the liquid outlet. A loose cylindrical weight 39, with its lower end 40 rounded, holds the valve on its seat, and ribs 41 prevent the weight from closing the outlet 23 when the bottle is tilted. In a modification, Fig. 5, the disk valve 46 has a sharp rim to press into the cork seat 14 and a round top to engage the rounded side 40 of the weight 39. The wall at the top of the valve chamber is flat, and a disk 48 prevents the insertion of a tampering tool. The air passage in the member 15 is elongated and funnel-shaped at its upper end to receive the valve 29 when the latter is forced through the opening 32 in its seat. In another arrangement, Fig. 6, in which the pocket at the top of the attachment is dispensed with and the attachment is not inclined, the member 15 depends within the bottle neck, and the outlet 51 is of invertedfunnel shape. A cork 57 closes the upper end of the air inlet 27 during transit, and is held in position by the overhanging ledge 58 of a porcelain cap 55 carrying a cork 56 for the outlet 23.

Title: Improvements in or relating to method and apparatus for conditioning air
IPC: F24F6/04
Filed: 1948-06-16
Abstract: 654,518. Conditioning aid. FLEISHER, W. L. June 16, 1948, No. 16207. [Class 137] [Also in Group XII] Triethylene glycol, or other hygroscopic material in the poly hydric alcohols group, is used, as a concentrated aqueous solution, as the wetting agent for a filter element, or elements, in an air conditioning system, the concentration of the solution being so determined that in the operation of the system, during the heating season, release of water from the solution to the air maintains in the latter the desired relative humidity. When triethylene glycol is used, it comprises from 82 to 92 per cent by weight of the solution. As shown in Fig. 1, the solution is pumped by a pump 31 from a tank 27 to a pivoted bucket 13 which tips when a certain quantity of solution has been received. The solution, which is somewhat viscous, is thrown against the wall 19 and flows over the plate 20 to be delivered to the filter element 21. The solution collects in a sump 25c connected to the tank 27 by a hole 26, and the water used in humidifying the air is made up from a supply 28 under the control of a float valve 30 in the tank 27. The small amount of triethylene glycol lost by evaporation, is replaced from a container 61, a perforation in its bottom being closed by a hinged plate 66 which is opened momentarily by the dumping movement of the bucket 13. The air is sucked, by a fan 38, through a passage 11 and filters 21, 23, and is passed out through the passage 12 and the furnace, to the space being ventilated. The filters 21, 23 are arranged in inverted V-form, the filter 23 being used to trap any droplets of solution which are entrained in the air passing through the filter 21. The trapped solution falls to the plate 25a and passes to the sump 25c. The motor 32 driving the pump 31, and the motor driving the fan 38 are controlled by the thermostat in the living space, so that, when the temperature rises the apparatus becomes inoperative. A number of inverted V-units of two filters 21, 23 may be superposed, the drainings from a unit being led to the unit next below, and the lowermost unit draining into the sump. The filters may be constructed as described in Specification 603,152, [Group XII].

Abstract: 821,225. Tractor power-lift mechanisms. WRIGHT, J. C. June 11, 1956 [June 10, 1955], No. 16779/55. Class 79(1) An automatic depth control apparatus for an implement 32, Fig. 1, mounted on a tractor so as to be raised and lowered by a hydraulic lifting mechanism 21, 22 and 27 to 30, has a valve means 1 mounted on the implement and operated by the movements of a ground wheel 2 of the implement, the valve means controlling the flow of hydraulic fluid to the lifting mechanism so as to control the working depth of the implement. As shown, the ground wheel 2 is carried by a bell-crank lever 3 pivoted at 4, to the plough 32, the latter being connected to a tractor and liftable and lowerable by a hydraulic lift 21, 22, bell-crank 28, 31 pivoted on the the tractor and a lifting link 30. The bellcrank 3 is connected by a swivel nut 7 to an adjusting screw 8, passing through a socket 9 mounted on a swivel 10 on a part 11 of the plough 32, the upper end of the screw 8 having an operating handle 12. The screw 8 is connected, between two collars 15, with a swivel connection 13 having a slidable connection with a control lever 14 of a disc type main valve 1 mounted on the plough. A pump 18 is connected by a flexible hose 16 to the inlet of the valve 1 the outlet of which is connected by another hose 17 with a secondary manually operable valve 19 communicating with a sump. The pump 18 is also connected by a smaller hose 20 with the lift cylinder 21. The valve 1 has a disc with an eccentric opening which is registerable with an outlet opening connected to the hose 17. When the tractor is operating the valve 19 is open and if the wheel 2 is lifted the opening in the disc moves out of registry with the outlet of the valve 1 and thus pressure builds up in the cylinder 21 to cause the plough to lift. When the wheel 2 frees, the disc opening moves into registration with the valve outlet and" relieves the cylinder, so that the plough can fall. Normal lifting and lowering of the plough is effected by operating the valve 19 and the depth of the plough is adjusted by the handle 12.
