Title: Improvements in or relating to Textile Decatizing Apparatus
IPC: D06C7/00
Filed: 1969-01-30
Abstract: Textile material (and interleaving backing) is wound on to a perforated hollow roll 4 mounted crosswise in a shallow cylindrical decatising chamber 1 having a bayonet-fitting lid 2. The diameter of the chamber may be 3.8 - 4.8 times its depth. The inner end of the cylinder may be outwardly curved to enable steam pressures of up to 4 atmospheres (gauge) to be employed. Radiant heat may be counteracted by internal baffles and cooling air supplied to slits around the opening of the chamber and a movable nozzle. The process comprises the successive steps of winding the material on the roll (Fig. 2) closing the lid and supplying steam to the roll (Fig. 3) releasing the steam pressure, opening the lid and applying suction to the roll (Fig. 4) and unwinding the material (Fig. 5).

Title: Housings for Electrical Connectors
IPC: H01R13/115
Filed: 1968-02-10
Abstract: A connector housing 11 of resilient insulating material comprises an open-ended tubular body having flexible side walls 13 each comprising an outwardly curved portion, stop means 18 extending from a wall at/adjacent an open end of the body and a projection 16 extending inwardly from the upper/lower wall at a location intermediate the ends of the body. To insert a connector in the housing, the walls 13 are pressed towards each other under finger pressure causing the walls 13 to unbow and the walls 12a, 12b to move apart. The connector is inserted (Fig. 4, not shown) until its leading end engages the stops 18, the connector walls (8, Fig. 1, not shown) freely passing the projection 16. On releasing the pressure on the walls 13, the walls 12a, 12b move towards their original positions, the projection 16 enters a space in the connector which is thus locked in position and a rib 14 extending centrally of the wall 12a and terminating in the transverse projection 16 maintains the connecter longitudinally aligned with the housing. To remove the connector, finger pressure is applied laterally to walls 13 to cause the walls 12a, 12b to move apart so that the rib 14 and projection 16 are lifted free of the connector which is then free to be withdrawn. The side walls 13 may be longitudinally corrugated to increase their flexibility. The curved portion may extend over only part of the width of the wall and the wall may have two or more such curved portions.

Patent ES-469595-A1 (ES)
Title: Extractor assembly for rimless cartridges
IPC: F41A15/02
Filed: 1978-05-09
Abstract: Disclosed is an extractor assembly including an extractor rod splined within a revolver cylinder and carrying spring leaf extractor segments in elongated grooves about its outer surface. The segments are prebent and biased in the assembly to displace extractor tips carried thereby radially outwardly. When the extractor assembly is fully seated within the revolver cylinder, cam surfaces on the cylinder maintain the extractor tips spaced radially inwardly of the cylinder chambers. Upon axial displacement of the extractor assembly, the extractor tips, under the natural bias of the segments, move radially outwardly into the grooves of the cartridge casings whereby the tips displace the casings rearwardly from the cylinder chambers. Upon spring return of the extractor assembly into the cylinder, the extractor tips are cammed radially inwardly and out of the chambers enabling the cylinder to be loaded.
