Patent DE-2121520-A1 (DE)
Title: Standardisation of pore sizes - in ore agglomerates
IPC: C22B1/14
Filed: 1971-05-03
Abstract: Combustible or volatile material is added to the ore to be agglomerated and is then partly or completely removed during subsequent hot processing, (sintering or reduction). The ratio of fines : volatile can be 2,3 or 4 : 1. The volatilisation or combustion of this material gives rise to uniform porosity and also improves the subsequent heat balance, aids further reduction (e.g. by depositing C in iron ore pellets) and favourably improving the smeltability of the pellets.

Abstract: 1346043 Carrying liquefied gases BRIDGESTONE LIQUEFIED GAS CO Ltd 8 Dec 1972 [28 Dec 1971] 56643/72 Heading B7A [Also in Division F4] A tanker ship for carrying liquefied gases has a membrane tank 3 which is so arranged that the hull 1 of the ship does not need to support the tank for the latter's full height. The tank 3 is contained in a box 4, with the interposition of a compression resisting, thermally insulating layer 2. The bottom and side walls 4 1  and 4 11  of the box can maintain the tank structure in a given shape when it is unloaded but not when it is loaded. The curved part 3b of the tank is strong enough, because of its curvature, to resist the tank internal pressure so that the hull 1, which resists the pressure on the lower parts of the tank structure, need only extend up to the level of the bottom of the part 3b. The tank structure and the hull may be made separately and the tank then lowered into the hull.

Title: Jets for welding, heating, cutting and flame-gouging - gas supplied through concentric grooves with press. balancing and mixing chambers
Inventor: CENI FREDERICK
IPC: F23D14/52
Filed: 1973-04-03
Abstract: A gas jet with a central hole for cutting-oxygen and two concentric ring-grooves, the inner annulus being used to supply heating gas and the outer ring for supplying heating-oxygen. The outer concentric channel leads to a press. equalisation chamber, from which the heating oxygen goes to a conical mixing chamber where it meets the heating gas, and the mixt. then leaves the jet. For simplicity in mfr. and repair, the jet consists of a body, base and plug so that the various dias. and sections are easily obtd. When a jet is only required for welding or heating, the central hole for cutting-oxygen is unnecessary. Flat jets can also be made with a similar configuration. The jets are not sensitive to press. fluctuations or inaccurate adjustment, and optimum use of gas is obtd.

Title: Self-shaping earplugs - with silicon putty filler
Inventor: MILLS ALLEN WILLIAM PROF
IPC: A61F11/08
Filed: 1973-04-18
Abstract: Dumbbell-shaped earplug has a resilient, elastic, pref. natural latex or rubber envelope with an expansible hollow cavity at either end, interconnected via a commissure. The filler, in the envelope, can flow slowly through the commissure when one cavity is squeezed; it is unyielding to acoustic vibrations, but flows under sustained pressure, to permit one cavity to be compressed for long enough for insertion into the ear canal. The other cavity then drives the filler back into the compressed cavity. A stiffening member forms the earplug's major axis, and is coupled to the cavity portions of the envelop; it is tiff enough lengthwise to transmit an inserting force.

Title: Multiple telescopic fitting for extension table tops - has large arc for guide rollers allowing easier movement
IPC: A47B46/00
Filed: 1974-02-28
Abstract: The telescopic fitting for the extending table tops which are housed in cupboards includes an outer telescopic tube with a holder for fastening the extending table top and a fastening plate which is provided on the fixed guide of the innermost telescopic tube to fasten a stop on a side wall of the cupboard. This guide is less than half the length of the cupboard depth and is set at a distance at right angles to the plane of the fastening plate. The arc along which the guide rollers for the individual extension plates of the extending table top are attached to the fastening plate has a radius at least nearly half the depth of the cupboard, and allows the extension plates to move more easily over the rollers from their horizontal to vertical positions. Since the plane of the rollers and the longitudinal direction of the multiple telescope are off-set relative to each other at right angles to the plane of the rollers the telescope can be mounted directly beneath the fastening plate.
