Filed: 1941-07-24
Abstract: 550,924. Dashpots. BROOKHIRST SWITCHGEAR, Ltd., and BARNES, J. H. July 24, 1941, No. 9363. [Class 108 (iii) [Also in Group XXXVII] The action of an electric circuit breaker is restrained by a dashpot in such a way that a port, the size of which can be pre-set, is controlled by a valve in the form of a helical or spiral spring one end of which forms a flap adapted to close the port when a sudden unsustained force is applied to the piston in the operative direction. The opening movement of the circuit breaker moves pistong 11 upwards in its cylinder 10 by polygonal piston rod 12 having a selected one of a number of throttling orifices 14 in the piston in action and controlled by a spring valve 19 which is normally open. This valve consists of a flat curved spring having one end fixed at 20 to the disc 15 and having a flap 21 at its other end co-operating with a hole 16 in the disc. For small sustained overloads the upward movement of the piston is restrained by throttling through the selected orifice 14 in the piston, the valve remaining open ; but for heavy momentary overloads, the valve closes orifice 14 and prevents operation of the cut-out. The disc 15 may be adjusted relatively to the piston to bring any one of the spaced holes 14 in the piston under the flap 21 of the spring valve by raising it to a part 18 of the rod where it can be turned and then lowering it again on to the hexagonal rod, The disc 15 lifts and allows free downward or return movement, additional orifices 23 being provided to assist this action. Upward movement of the valve is limited. Specifications 24392/10, [Class 108 (iii)], 480,805 and 533,040 are referred to.

Title: Detector apparatus for use in connection with the filling of containers with pliant or granular material
IPC: B65B1/48
Filed: 1956-03-27
Abstract: 783,065. Packaging. DU PONT DE NEMOURS & CO., E. I. March 27, 1956 [March 28, 1955], No. 9465/56. Class 94(1). [Also in Group XXI] A device for detecting and ejecting a partially filled flexible walled container, such as an explosive cartridge, includes a head for contacting the container surface, movement of the head past a predetermined point causing a reciprocating plunger to eject the container under test. Charged containers 1 are fed beneath a head 4 movable downwards by pressure applied to a bellows 3 via lines 2a, 2b and valve 2. A properly filled container prevents movement of the head 4 beyond position 11 on the Figure, but a partially filled one permits movement below this position. Such movement causes a valve member 5 to descend permitting pressure air from a lead 8 to charge a reservoir 9. The bellows 3 is then exhausted through the valve 2 and the member 5 rises to connect the reservoir 9 to the ejector cylinder 14 via a lead 8b. The ejector ram 16 advances against low pressure air supplied through a lead 11, to remove the container 1. When the ram piston 15 passes a lead 12, the pressure air is admitted to a valve 13 causing it to exhaust the reservoir 9 and cylinder 14. The valve 13 is then closed under the time delay action of a dashpot 13a and the ram 16 is returned by the low pressure air from the lead 11. Hydraulic or other control systems (not described) may be employed in lieu of the pneumatic arrangements detailed above. Series of heads and rams operating simultaneously may be provided.

Filed: 1920-04-06
Abstract: 159,771. Semple, J. B. April 6, 1920. Projectile fuzes.-Relates to selectively-acting combined direct and delay-action percussion fuzes, and consists of an inertia member actuated by a strong impact of the shell, to convert the fuze from a quick-action to a delay-action fuze, before the percussion pellet has struck the percussion cap of the fuze. On impact of the shell, the cap is fired by the striker 3, and, in the normal position shown in the Figure, the flash can pass to the priming charge 17 through an open flashway 6, 10, 7, and more slowly by way of the passages 6, 9, 8 containing a slowburning charge 9. If the shell meets with small resistance on impact, the flashway 6, 10, 7 remains open and the fuze is quick-acting. If, however, greater resistance is met with, a pin 12 retaining an inertia member 11 is sheared and the inertia member closes the flashway 7 before the detonator is fired, so that the fuze acts only with delay.
