IPC: B29C67/04
Filed: 1963-12-04
Abstract: Production of a porous body by filling a die with small graded pieces or particles of a thermoplastic material, closing the die, and heating the closed die to a temperature sufficient to cause the pieces or particles to sinter together the distribution of heat being controlled so as to intensify the degree of softening of the particles in predetermined regions of the body to effect local strengthening of the body in those regions preferably so that the body is sealed locally against the passage of liquid or gas by intensifying the degree of softening in the regions to be sealed sufficiently to destroy the porosity of the body in those regions. The preferred thermoplastic material, polystyrene, can be used in the form of rods, spherical beads or crushed particles for which limits defining useful sizes are given.  Specified regions of the products, e.g. tiles or conical tubes, may be rendered completely non-porous. The distribution of heat in a selected region may be controlled by decreasing the thickness of the die wall in that region, by a local increase in the output of the heating medium or by use of a longer period of heating time.

Filed: 1974-11-11
Abstract: 1475170 Socket connector CONTACTUM Ltd 11 Nov 1975 [11 Nov 1974] 48777/74 Heading H2E A shuttered electrical socket connector wherein in response to the application to a single shutter member of a force resulting from the simultaneous presentation of contact pins in apertures in a cover member of the connector, the shutter is subject to a translatory movement in a plane perpendicular to the direction of entrance of the pins, but in response to a force applied by an object presented in one only of the apertures, will respond by limited rotation in the same plane so that a portion engages an abutment which prevents translatory movement. In an embodiment, (Figs. 1 and 2) the connector 10 comprises a cover member 11 with apertures 12, 13, a shutter member 14 and a base member 20. A spring 15 abuts against the end of slot 14e and a projection 11a inside the cover 11. The face of the shutter 14, opposing the cover 11, has bevelled portions 14f, 14g (Fig. 5) so that when pins (24, 25) of a plug (Fig. 3, not shown) are urged into apertures 12, 13 the shutter is displaced against the bias exerted by spring 15, allowing the pins to enter the respective socket contacts 16 (Fig. 3, not shown). If an object is thrust into only one aperture the shutter will rotate in its own plane until one of projections 14d engages an abutment 11b, preventing any further movement of the shutter (Fig. 4, not shown). In an alternative embodiment (Figs. 7-13, not shown) the shutter (34) is used in a three-pin to two pin fused adapter (32) for use with an electric razor. The shutter (34, Fig. 12, not shown) has a body portion (34a) having rounded laterally extending wings (34b), a tapering extension (34c), extending from the body portion, ending in a laterally extending head portion (34d); body portion (34a) has a central groove (34e) in which a rib (32f, Fig. 9, not shown) extends and on either side of this groove there are two shorter slots (34f) forming spring pockets for springs (35). A fuse carrier (44, Fig. 13, not shown) used with this connector, has a cover-plate (44a) from the centre of which extends a cylindrical part (44b) having a circular bore (44c) which accepts a fuse cartridge (45) so that the fuse is parallel to the coverplate. In another embodiment (Fig. 14) the shutter 51 slides behind a cover member 50 which has apertures 50a, 50b masked by the shutter in its normal position. A central slot 51d on shutter 51 receives spring 53, which also abuts an abutment 50c secured to cover 10. The sides of abutment 50c which face the sides of slot 51d are provided with serrations 50d and the facing portions of the sides of slot 51d have matching serrations 51c so that when an object is introduced in only one of the apertures 50a or 50b the serrations interfere between them to prevent movement of the shutter. The means adapted to guide the shutter 51 consist of a large washer (54, Fig. 15, not shown) held by a screw (55) engaging in a tapped hole (50e) on the abutment 50c.

Before and after rupture surfaces 42 and 43 respectively of the bolt bear on the workpiece, the head 32 being held stationary while the nut 44 is tightened by a torquemeasuring spanner 46 which enables a torque reading to be taken at the moment of rupture so that the nut can be tightened again until the same reading is obtained with the surface 43 engaging the workpiece instead of the surface 42. In other embodiments the flange and shear section are formed on the nut or on a washer associated with either the head of the bolt or with the nut.

[Also in Division C7] An electrolytic etching process for the preparation of a porous, gas-permeable, gas-solvent, fuel-cell electrode comprises masking the surface of an alloy of a first metal and a second metal with a porous or perforated cover, the cover being in contact with the surface of the alloy, and exposing the alloy as anode in an electrolytic bath at a current density in the range of from 1 to 20 milliamps/sq. cm. based on the area of the exposed surface of the alloy and at a voltage at which the second, but not the first, metal will be dissolved out of the alloy until at least 80% by weight of the second metal has been dissolved from the part of the alloy that is masked by the porous or perforated cover. The " exposed surface of the alloy " is that part which at the beginning of the process lies beneath the pores or perforations of the cover. The first metal may be Ag, Au, Pt, Pd, Ni or an alloy of one of these metals with another or with Hg, e.g. Ag-Au or Au-Hg. The second metal may be Cu, Zn, Cd, Al or Si or an alloy of one of said metals with another. The mask may be a perforated sheet of synthetic plastic or may be a plate of porous carbon. All the second metal may be dissolved in which case the remaining electrode metal becomes entangled by the carbon and supported by it. The electrolyte may be an aqueous solution containing ions of the second metal and the cathode may consist of the second metal. The current may be reduced as electrolysis proceeds and may be reversed for a short interval during dissolution. In Examples 1 and 2, 80% by weight and all the Cu is respectively dissolved from a Cu-Ag alloy using a CuSO 4  electrolyte. The porous electrodes so formed are used as oxygen-electrodes in fuel cells. Fig. 3 shows the fuel cell of Example 2. The oxygenelectrode comprises Ag granules 17 between carbon discs 14, 15. Oxygen is supplied through a Ag tube 12. The anodes comprise Ni nets 18 filled with " Raney " (Registered Trade Mark) nickel 19. The electrolyte 7 is a 6N KOH solution containing 12% by weight of ethylene glycol as fuel.
