Abstract: 672,120. Fluid-actuated valves. TROENDLE, J. A. April 21, 1948 [May 2, 1947], No. 10957/48. Class 135 [Also in Group XXVIII An automatic shut-off valve for a fluid-pressure system comprises a spring-loaded closure member 12 actuated through a rod 14 by a cam surface 16 on a plunger 17 attached to a bellows 18. The valve controls communication between a reservoir 10 and a duct 13, and the member 12 is held off its seat by reservoir pressure arising in the bellows via a passage 15 and a port 19a. When the reservoir pressure falls below a predetermined value, a spring 18b moves the plunger and cam to permit the spring 22 to seat the member 12. In a modification, the cam 16 is formed on a piston acted on by reservoir pressure. In a further modification, the bellows is in axial alignment with the closure member and acts thereon through a stirrup-shaped member.

Title: Improvements in and relating to filling machines, and the like for use in the automatic packing of cigarettes and other articles
IPC: B65B19/32
Filed: 1922-04-20
Abstract: 197,173. Molins, W. E. April 20, 1922. Packeting cigarettes &c. in cartons.- Relates to machines for packeting cigarettes &c. into slide and shell or like packets or cartons, and consists in providing means whereby a carton &c. which has received an insufficient number of cigarettes is closed or partially closed in such a manner that the omission is evident. Packets comprising an inner slide already partially inserted in an outer shell are forwarded on a convever in the direction of the arrow 1, Fig. 3, and are closed by an arm a, Fig. 1, pivoted at b and carrying a closing piece c stepped at c<2>, c<3>, Fig. 6, to effect the closing in two stages. At each inward stroke, the step c<2> closes a packet to the extent shown at 2, Fig. 6, and the step c<3> completes the closing as shown at 5. The arm a carries a spring controlled pawl d which contacts with a plate e pivoted at f on a plate g and pushes it over until the pawl trips. The end h is thus caused to depress the flap 4 of a slide and to allow the shell to pass over it. A detector r, which is normally kept raised by a tongue k on the plate e, rests on the cigarettes, but if a cigarette is absent from the top row, descends into the packet and tilts a lever u so that the point v contacts with a plate w on the arm a and prevents closure from being effected to the extent shown at 2, Fig. 6. The flap 4 is therefore free to rise again when the part h rises, and at the next step the shell is pushed over the slide with the flap outside it, and the faulty carton can be subsequently removed. Brushes p, Fig. 5, on the plate g ensure that the gap caused by a missing cigarette shall be in that part of the packet registering with the detector r. The invention may be applied to machines of the kind described in Specification 169,341.

Title: Improvements relating to telegraph circuit arrangements
IPC: H04L25/22
Filed: 1946-04-12
Abstract: 610,666. Code telegraphy; valve relay circuits. COLE, A. W. H., GRIFFITH, R. G., and CABLE & WIRELESS, Ltd. April 12, 1946. No. 11369. [Class 40 (iii)] [Also in Group XL (c)] A telegraph circuit arrangement for double current operation of two interconnected telegraph stations comprises at one of the stations two thermionic valves in series and so arranged that the closure of either transmitter contacts causes one of the valves to become more conductive and the other less conductive. When neither of the transmitter contacts T1, T2 is closed the suppressor grid Sg2 of a tetrode V2 is negatively biassed by the centre-tapped battery B and the valve does not conduct. Current flows therefore from the positive battery terminal through a tetrode VI, acting as a triode, over a line L1 and from left to right through receiver coils W1 and W2 and back to battery via earth. If either transmitter contact T1, T2 is closed, the suppressor grid Sg2 is earthed, and therefore connected to the midpoint of the battery B. The valve V2 conducts and its anode current flows from the centrepoint of the battery B via earth to line L1, from right to left through the receiver coils W2, W1, and through bias resistance Rb and. valve V2 to battery. The voltage drop in the bias resistance Rb biasses the valve V1 to cutoff. Thus, the valves V1, V2 and battery B installed at one of two inter-connected stations only, suffice to produce double-current working. Both valves are conveniently tetrodes, but the upper one V1 may be a triode. In a modification (Fig. 2, not shown), both valves work as triodes, and may be triodes, the transmitter contacts T1, T2 biassing the control grid of valve V2.
