Title: Structures having deformable members
IPC: B60R19/34
Filed: 1972-03-06
Abstract: 1376786 Energy absorbing devices SOC ANON AUTOMOBILES CITROEN 6 March 1972 [19 March 1971] 10256/72 Heading F2E A deformable structure comprises a substantially undeformable body and a plastically deformable member substituted by two sheets each sheet having a first portion, contacting the first portion of the other sheet in face-to-face relationship, and a second portion including a loop extending through approximately 180 degrees the loops extending in opposite directions and being secured to the body a guide element for each loop so that upon deformation each loop moves along its respective guide element, the first portions progressively separating, and being guided by further means. The sheets each comprise three pairs of bands 4, 5, 6, of decreasing thickness from the centre and held in a sleeve comprising the two outside bands joined by two lateral bands. The bands 4, 5, 6 are adhered preferably by welding spots and are held at the other end in a sleeve 11, e.g. in a vehicle bumper or steering-column. The rigid body is a rectangular cross-section box 1 having a reinforced end 1a with an end cap 13 providing the guide means 12. The bands 4, 5, 6 are further looped around the end 1c of the box 1 or they extend laterally, Fig. 5, and are held by bolts to the box 1. The guide elements comprise two walls 3b spaced from the box walls tapering toward the box walls near the end 1c and joined by two opposed walls adjacent the box walls. Alternatively, the guide elements comprise two opposed solid parts providing a similar guide profile to the guide elements 3b. When a compressive load is applied to the sleeve 11, the bands absorb energy by the deformation due to new loop formation along the elements 3b and by the rupture of the adhesion points between the two central bonds 4. The sleeve surrounding the sheets does not inhibit deformation since notches are provided at the corners, running the length of the sleeve, to provide easy rupture.

Title: Improvements in or relating to the manufacture of catalysts
Inventor: MORGAN CYRIL ALFRED
IPC: B01J37/03
Filed: 1952-04-28
Abstract: Palladium catalyst is prepared by adsorbing a palladium salt from solution on to an alumina carrier and treating with a water-soluble metal hydroxide or carbonate to form a hydrated palladium oxide or basic carbonate, which is thereafter reduced to metallic palladium. Activated gamma-alumina or gamma-alumina monohydrate of coarse or fine particle size is stirred for a short time with a solution of palladium chloride, nitrate, or acetate, the slurry is filtered and washed, the solid stirred with caustic soda solution and again filtered and washed; further treatments with palladium salt solutions may be given, using the filtrate from the first stage or solutions of higher concentration.  The amount of acid in the palladium salt solution should be limited to that required for complete solution of the salt.  The palladium content of the final catalyst is 0.01-10 per cent., varying with the particle size of the alumina.  The catalyst is used in the hydrogenation stage of the cyclic process for the manufacture of hydrogen peroxide by autoxidation of anthraquinhydrones, for example as described in Specification 718,305; before use the catalyst is reduced with a mixture of hydrogen and nitrogen of increasing hydrogen content, or reduction may be effected in the hydrogenator.  Regeneration of the catalyst may be carried out by thermal oxidation of the adsorbed organic matter, followed if necessary by reduction.  Specification 508,081 also is referred to.  The Provisional Specification refers also to the use of charcoal as the carrier.
