Abstract: 1,029,892. Making elbow fittings; angular bending. NEDERLANDSE ORGANISTATIE VOOR TOEGEPAST - NATUURWETENSCHOPPIJ ONDERZOEK TEN BEHOEVE VAN NIJVERHEED HANDEL EN VERKEER. Feb. 20, 1964 [Feb. 20, 1963], No. 7172/64. Headings B3A and B3E. Apparatus for making elbow fittings from straight tubing comprises two die halves 2, 8 coupled together in a frame 1, the halves being relatively movable parallel to their surface of contact, each having a bore which opens into the contact surface and a pressure transmitting plunger adapted to be moved in at least one of the bores towards the surface of contact, at least one of the halves in the part adjacent to the surface having a groove linking up with the bore into which a cam mounted on the other half is slidably located. A length of tubing 23 is inserted in the aligned bores 4, 13 of dies 2, 8 and located on the end 22 of a shouldered plunger 14. The tubing is filled with a substantially incompressible medium 24, such as oil or rubber, the end closed by a shouldered plunger 5 and the assembly located in a frame 1, the upper die 2 being aligned with respect to the lower die by bolts 3. A carrier 16 supporting the die 8 and an hydraulic jack 15 is slidable along the floor of the base and the die 8 guided in respect to die 2 by cams 12, 10 thereon engaging complementary semicircular or other suitably shaped grooves 11, 9 therein. One or both plungers 5, 22 are depressed by jacks 6, 15 to bottom the shoulders thereof against the tube ends to pressurize the medium 24 which expands the tube against the bores whilst continued loading of the tube subjects it to plastic deformation and the lower die 8 moves transversely to form a double right-angled elbow fitting which is subsequently divided to form a pair of elbows. In a modification, the cam portions which may be integral with the dies or inserted therein, are located away from the proximity of the bores, Fig. 2 (not shown), so that an elbow having a large radiused outer bend may be formed. An additional lateral force may be applied to initially move the lower die. To produce a single 90 degrees elbow the groove may be formed in one half die only, the other die having a cam, and the contact line between the dies arranged at the top or bottom of the horizontal part of the bent tube.

Abstract: 549,881. Fluid pressure responsive devices. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). June 6, 1941, No. 7198. [Class 40 (i)] [Also in Group XIX] In a fluid-pressure responsive device for converting pressure variations into a variaable electric quantity by subjecting a diaphragm to the pressure, the diaphragm is mounted in a holder so that the electrical characteristics of the device are not affected by strains set up when the diaphragm is secured in position in the holder or when the holder is mounted on the apparatus to be tested. Temperature compensation is also effected. The device responds by a variation of capacity and is arranged to be screwed into the wall of the cylinder of an I.C. engine. A holder 1 screwed externally at its lower end for insertion in the cylinder is internally screwed at its upper end to receive the member 2 which carries the diaphragm 5 at the end of its lower portion and extends some distance beyond the seal 3 entirely freely in the lower portion of the holder. The diaphragm 5 co-operates with a plate 6 to form a variable capacity, the plate 6 being carried by a thickened part 7 of a rod 8 which is secured by a collar 9 and set screw in a ceramic bush 10 fixed in member 2. The lower end of the holder 1 has a perforated wall 13 and the diaphragm may be protected from hot gases by a mica plate. Cooling is improved by coating the parts 4, 5 with good thermally conductive material, e.g. copper or silver, and temperature compensation is effected by suitable choice of materials for the parts 4 .. 7.

Containers 13 are held by their rims in three slots at 120 degrees on stepping table 17, entering at 23, punched at 24 and discharged at 25. The principles of selection of stamps and punches by control unit 49 are not described: after completion of marking a previous container, control starts main motor 27 and punching rotor 38. Motor 27 steps the table forward 120 degrees, and via lifting drive 29 raises the punch block 33 and associated cylinder 34 and punches 35, the operative punches for the first column being selected by control 49 via electromagnetic coupling 37. The holes are punched and segment 45, heated by element 48, is turned by stepping motor 45, controlled by unit 49 to bring the required stamp 46 over the container rim. Control 49 then operates magnet 47 to stamp rim, and on completion energizes solenoid 40 to engage friction block 39 with the container rim, ready for stepping motor 41 to bring the next column of the containing skirt opposite punches 35. The selection of punches is changed by control 49 via coupling 37 and the cycle repeats until all the columns have been punched and the rim stamped correspondingly. The punch block 33 is then lowered ready for motor 27 to index the table through 120 degrees, bringing the coded container to discharge position 25 and introducing a new container at 24.
