Abstract: 472,508. Piston extrusion apparatus. MAGUIRE, G. A. Aug. 1, 1936, No. 21340. Convention date, Aug. 9, 1935. [Class 102 (ii)] In a container for dispensing paste a removable cartridge 26 is provided with a piston 31, through which a rod 29 is screwed. The piston rests on'projections 35 pressed in the interior of the cartridge. The latter is inserted in a casing 10 having a discharge passage 15 with an inward projection 24, which enters the discharge opening in the cartridge. Projections 37 at the lower end of the cartridge engage slots in the container, and the edge of the cartridge is gripped between the serrated edge of the container and a bevelled surface on the screw cap 39. An operating member 53, shaped like a propeller in order to permit operation in one direction only, and housed in a recess in the cap 39, has a recessed projection passing through a hole in the cap and engaging the rod 29. One end of a split ring 52 is secured to the member 53, while the other end rides over ratchet teeth in a recess in the cap. The piston 31 is formed with a recess 32, which receives the projection 24, and with a projection which enters the passage 15. The latter can be covered by a rotatable cap 13 having a flange which engages a groove in the container. The cartridge may be transparent, and can be inspected through a window 59 in the container.

In a thermal cut-out, the cup-shaped end of 25, Fig. 2, of contact 24, is urged against the end of terminal 14 by a spring 30 acting through a bushing 28 of a non-metallic material, such as α - hydroxy - α - phenylacetophenone, which softens at a predetermined temperature and an insulating piston 22 supporting the contact 24. When the ambient temperature rises to said predetermined value the bushing 28 softens and a second spring 26 forces the contact 24 away from the terminal 14. In a second embodiment, Fig. 6, a plurality of plunger-type contacts such as 80, 82 are normally bridged by the corresponding contacts 88, 90 carried by the flange 55<SP>1</SP> of a cup-shaped conducting member 54<SP>1</SP> which is urged by spring 64<SP>1</SP> through softenable pellet 60<SP>1</SP> to the bridging position.

Abstract: 1483677 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 22 May 1975 [12 June 1974] 22128/75 Heading H4K A line loop detector includes a differential amplifier having its positive input coupled to the line via a fast time constant circuit and its negative input coupled to the line via a slow time constant circuit. When a steady line state is maintained for a period of twice the slow time constant circuit both time constant capacitors C1 and C2 become charged to the same level dependent on whether the subscribers hook Switch 1 is open or closed. The output V T  of the differential amplifier is zero. Any transient on the line of duration less than the time constant determined by capacitor C2 has no effect on the system. Looping of the line causes both capacitors to charge positively but as C2 charges more rapidly than C1 the output V T  goes positive during charging turning on a transistor T1 providing an off-hook signal via a light diode photo transistor coupling OC1. Returning the handset to the on-hook condition causes the capacitors C1 and C2 to discharge, C2 discharging more rapidly producing a negative output at V T  which produces an on-hook indication via photo-coupling OC1.
