Abstract: 689,951. Hand trucks. SALSAS, A. P. July 16, 1951 [Aug. 7, 1950], No. 16833/51. Class 108 (i). [Also in Group XXX] An automatic conveyer elevator truck comprises a pair of arms 3, 4 pivoted on a transverse axis to brackets 2 secured to the handle 1. To the outer ends of these arms are pivoted at 9 load-engaging arms 10 which are moved away from each other by the action of the guides 13 against the fixed bar 15 when the truck is tilted forwardly and the ground-engaging wheel 5 causes the arms 3, 4 to be rotated anti-clockwise (Fig. 1). The separation of the arms 10 to enable different dimensioned loads to be carried is varied by screws 7 which limit the downward movement of the arms 3 and thus determine the position along the inclined parts 14 of the guides 13 at which the fixed bars 15 make contact. In operation the truck is wheeled along to the object 81 in an upright position with the wheels 5 engaging the ground and the arms 10 held apart. When the arms 19 contact the loadembracing arms at the upper ends of the shafts 20 engage the load to enable it to be tipped about its edge 22. Further tilting of the truck allows the arms 3, 4 to rotate clockwise, thus enabling the arms 10 to engage under the load to enable it to be supported and wheeled away.

Title: Improved method of, and apparatus for aerating liquids
IPC: B67D1/00
Filed: 1932-06-16
Abstract: 392,750. Aerating liquids. SODASTREAM, Ltd. and HUCKS, W., 22, Oval Road, Camden Town, London. June 16, 1932, No. 17063. [Class 14 (i).] Water is admitted from an inverted bottle 2 by way of a pipe 5, passage-way 6, and inlet valve 7 to an aerating chamber 3, communicating through a tubular piece 12 with a discharge vessel 4. The tubular piece 12 projects into the aerating chamber 3 and forms an air-lock space 14 into which a needle-jet 16 for the supply of carbonating gas projects. A combined discharge and safety valve 13 controlling the outlet port of the aerating chamber -3 is operated by a hand-lever 19. The valve 13 is connected by a shackle 27 to a pin 20 passed transversely through a tubular piece 21 having secured thereto a guiding element 22 slidable in the vessel 4, and through the ends of a pair of eccentric straps 23 mounted on an eccentric 24 rotatably mounted on a shaft 25 fixed in a slotted extension 26 of the vessel 4. Outwardly bent ends of the shackle 27 fit into holes in a collar on the valve 13, and the looped end of the shackle is normally held in engagement with the pin 20 by a spring 28. When the valve 13 is closed, a predetermined pressure is exerted by the spring 28 to maintain it on its seating, but should the pressure in the chamber 3 exceed this amount, the valve is raised until the excess pressure is relieved. The valve 13 is coupled with the valve 7 by means of a disc 30 slidable in a socket 31 in such a manner that the valve 13 is opened before the valve 7 when the lever 19 is raised, thus first relieving the pressure in the chamber 3 which would otherwise force the aerated liquid back into the vessel 2. The supply of the aerated liquid through a discharge spout 33 to a glass or other receptacle is thus effected by the inflow under gravity of a succeeding supply of non-aerated liquid from the vessel 2. A device 34 may be provided on the hand-lever 19 for counting the number of times the apparatus is operated. The pipe 5 provided with an extension 5a acting as a drain, and normally closed by a cap 5b.

Title: Method and apparatus for recording seismic signals
IPC: G01V1/24
Filed: 1975-04-24
Abstract: 1510681 Seismic exploration COMPAGNIE GENERALE DE GEOPHYSIQUE 24 April 1975 [30 April 1974] 17104/75 Heading G1G In a marine seismic exploration system a main line of N seismic detectors is spaced from a seismic source, an auxiliary line of n (<N) closer-spaced detectors is positioned nearer the source, the N detectors of the main line are connected to respective channels of a recorder, the n detectors of the auxiliary line are connected in common with the more distant detectors of the main line to n of the N channels, and signals from the auxiliary line are attenuated relative to those from the main line. This arrangement enables reflection signals received by the auxiliary line from shallow subsurface reflectors to be recorded in the common channels prior to arrival of reflection signals at the main line, so avoiding the need for separate recording channels for the auxiliary line. In the described embodiment the auxiliary detectors are connected via resistive attenuators to the common channels. The attenuation is needed because the acoustic wave paths to the auxiliary detectors are generally shorter than those to the main detectors.
