Abstract: 1482906 Suction grippers VACU-LIFT MASCHINENBAU GmbH 21 Oct 1974 [16 Nov 1973] 45521/74 Heading B8H A vacuum lifting device for lifting cylindrical articles comprises a lifting beam 2 with a lifting eye 9 and incorporating vacuum reseroirs 81 and a vacuum pump 10, and suction heads 5. Each head comprises a peripheral sealing ring 15 with a series of segments 17, embedded in a sealing plate 18. Each segment 17 is connected to a respective suspension strap 52, 54, 58, 59 forming a linkwork coupled to a slider 46 which has an elongate slot 47 to receive bolts 48, 37. The bolt 37 is coupled to a belt-crank 34 itself coupled to an axle 23 movable with bolts 19 which secure the head to the beam and which are vertically displaceable relative to the head. The bolt 37 mounts brake pads 41, 42 which, when the device is lifted, act on the slider 46 to secure same and, through the linkwork, the segments relative to one another, whereby after the head has been positioned on an article and the segments have deflected relative to one another to correspond to the shape of the article, the segments are automatically locked in said shape when the lifting device is raised. The segments are released to move relative to one another after the load has been deposited.

Abstract: 1,131,062. Injection blow moulding. OWENS-ILLINOIS Inc. 29 Oct., 1965 [2 Nov., 1964], No. 45792/65. Heading B5A. Containers having an injection-moulded neck portion and a blow-moulded body are produced in apparatus comprising an injection moulding station and article removal station, spaced horizontally and vertically and located one above and one below a support element arcuately movable between positions in a horizontal plane, at least one parison core and neck mould mounted on and movable with the support element and actuable vertically for positioning at each station and at least one pair of blow mould sections mounted on and movable with the support element and arranged on either side of the vertical axis of the parison core and neck mould to co-operate therewith in blowing the body. As shown in Fig. 1, the apparatus comprises a rotary table 31 having posts 35 on which crosspieces 37 slide, vertically reciprocated by pistons 40 mounted on an upper tie support member 36. Crosspieces 37 carry parison cores 83 (Fig. 2) mounted in block 63. Air for expanding the parison is passed through core 83 when cap 91 is opened by member 101 depressing rod 99 to which cap 91 is fixed, member 101 itself being moved by air supplied to piston 107 through inlet 108. Air for expansion is admitted through inlet 112 (Fig. 3) passing down between rod 90 and sleeve 95. Crosspieces 37 carrying parison cores 83 and neck moulds 150 are lowered through orifices 176 (Fig. 8) in table 131 to injection moulds 172 fixed to support 23 and having valve rod 190 to stop injection when desired. Screw 182 may be axially reciprocable due to pressure build-up or to external means. Crosspieces 37 carrying the injected parison and neck are raised and blow-moulds 195, sliding on guide rails 94 are closed about the parison, and the parison is blown therein while the table 31 is rotated or oscillated to an ejection station (Figs. 9-12, not shown). As shown in Fig. 3, the neck is injection moulded at 200 in neck moulds 150, which are opened by action of wedge-pieces 145. Air is supplied to cylinder (68, Fig. 5, not shown) without any to cylinder 40, the wedge pieces 145 moving downwardly with the block 50 and sides 55 (Fig. 4, not shown), and thereby open the neck moulds 150 which are fixed to wedge pieces 145. This motion also causes strippers 155 to move downwardly by action of face 155a on the opening neck moulds 150, stripping the article from the core 83 into shoot (203, Fig. 11, not shown). The core 83 has heating and cooling inlets 117, 126 respectively and outlets 124, 134 respectively as shown in Fig. 3. During or after inflation, the table 31 is rotated or oscillated through 180 degrees and after article ejection, the empty cores may be used for injection of a further parison.

Title: Hardness testing
IPC: G01N3/48
Filed: 1972-10-11
Abstract: 1358131 Hardness testing E SCHMIDT 11 Oct 1972 [15 Oct 1971] 46995/72 Headings G1N and G1S The hardness of a specimen is tested by measuring the length of time for which a striking probe remains in contact with the specimen before rebounding from it. In Fig. 1 a metal specimen 2 is tested by striking it with a conductive hammer 1; while there is electrical contact between the hammer and the specimen capacitor 17 is charged, so that the resulting potential on the capacitor is a measure of the contact time and hence of the hardness. The contact time is largely independant of the hammer head velocity on striking the specimen. In the Fig. 2 embodiment the striking probe 10 is normally insulated from hammer 7; when specimen 20, which need not be conductive, is struck an insulating ring 11 is compressed so that probe 10 contacts hammer 7 and capacitor 17 commences charging. When the probe and hammer rebound from the specimen the contact is broken as the ring 11 expands and the timing ceases. Because the mass of probe 10 is small compared with that of the hammer the time measured is substantially the contact time between the probe and the specimen. When the probe mass is not relatively small a different calibration is required, as for example is necessary for Fig. 3. Here probe 28 initially rests on the specimen, and is struck by spring-loaded mass 22, the latter being loaded by drawing it to the right hand end of tube 21 with trigger 30, against a spring. The probe slides in insulating bush 27. When mass 22 first strikes the probe the timing is initiated; the probe then moves ahead of the mass into the specimen, and rebounds against the mass again. The second contact between the probe and the mass terminates the timing. In another embodiment, Fig. 6 (not shown), the mass falls on to a circular plate-like probe suitable for soil testing. The probe may be driven against the specimen manually, by spring, by gravity, or by a solenoid. The time may be measured as above, or by observing the output of a strain gauge, an accelerometer or a Piezo-crystal built into the apparatus. Only the duration of the signal is relevant, its magnitude being ignored. The probe dimensions are chosen to be suitable for the material tested. In Fig. 1 a suitable time constant in the measuring circuit must also be chosen for the specimen.

Title: Polyurethane resins

Filed: 1962-12-14
Abstract: A curable polyurethane is produced by stirring mechanically (1) an organic compound having at least 2 active hydrogen-containing groups and of MW at least 500 with (2) a polyhydric alcohol of MW below 750, at a temperature sufficient to liquefy both compounds and mixing (3) an organic polyisocyanate with the melt, the mechanical mixing being continued after the polyurethane has reached a solid state, but interrupting this mixing before the polyurethane resin is completely cured, the total number of active hydrogen atoms in compounds (1) and (2) being equal to or slightly in excess of the number of -NCO groups in the polyisocyanate. Polyesters and polyethers are suitable as compound (1) and many are listed.  Many suitable catalysts and compounds (2) of MW below 750 are mentioned.
