Title: Annular cyclone for expansion evapn of solids-contg. liqs - having tangential inlet with parallel vertical walls
Inventor: MUSCHELKNAUTZ EDGAR DR ING
IPC: B01D3/06
Filed: 1975-01-24
Abstract: A cyclone, for the expansion-evapn. of liqs. which contain solids, is generally annular with inwardly oblique walls at the bottom leading to a sepn. chamber, and with a tangential inlet, the cross-sectional area of which is 5-30 times that of the feed line leading into it; pref., the change from the feed line into this inlet box is abrupt. The inlet box tapers in width and increases in depth as it approaches the annular chamber. In the addn., the inner face of this inlet box continues into the inlet chamber parallel to the outerface of the inlet box. Both faces may be curved. Device is used for the expansion-evapn. of solids-contg. liqs., esp. where the solids have a grain size 100 mu. The provision of parallel, esp. curved side faces to the inlet box at its junction withthe annular sepn. chamber results in an increase inthe permissible throughput as a result of improved sepn. efficiency.

Title: Palladium silver alloy, esp for dental applications - with the addn. of titanium to improve adhesion of porcelain
Inventor: EURICH KLAUS
IPC: C22C5/04
Filed: 1975-05-30
Abstract: Palladium alloy for the baking on of porcelain, esp. for dental applications, contains by wt. 20-45% silver, 0.1-10% of at least one addn. (1) added to increase hardness, e.g. Fe, Ni, Co, the remainder being 50-80% Pd. The alloy also contains 0.1-0.5% titanium. Addn. (1) is pref. 0.1-6.0% Fe, and the alloy may also contain (a) 1.5% max. In and/or 1.5% max. Sn; (b) 2% max. Au and/or 2% max. Pt; (c) 1.5% max Ni and/or 5% Co; and/or (d) 1% max. copper. The alloy is used for dental prostheses, e.g. crowns and bridges, but also for jewellery. The addn. of max. 0.5% Ti improves the adhesion of porcelain and also improves the colour reproduction of the porcelain, without impairing the good melting and casting properties of the Pd alloys. Furthermore, the use of Ti combined with Fe produces a notable increase in hardness. Palladium alloys possess the advantage that they are less expensive and lighter than gold alloys.

Title: Crease and water proofing cellulose textiles - with aminoplasts and organosiloxanes applied after moisture conditioning by splashing water
Inventor: DEINER HANS
IPC: D06M15/643
Filed: 1975-07-04
Abstract: Parent Patent describes the simultaneous crease- and water-proofing of cellulose and cellulose-contg. textiles with aminoplasts and organosilxanes applied from organic solvents.

Title: Invalid chair lifting mechanism - has hydraulic rams on side frames thrusting downwards onto floor
Inventor: BONFIELD ROBERT BENHAM
IPC: A61G5/14
Filed: 1975-07-25
Abstract: The mechanism fits on the side frames (4) of the chair and incorporates hydraulic rams (12) extending downwards so as to bear against the floor (21) and thus raise the frames to a convenient height for the occupant to work at a table, kitchen stove etc. The rams can actuate extending frames with bars (21) resting flat on the ground, and the rams can be supplied by a hand pump and connected in series so that they extend and retract for an equal amount. As fluid is delivered against one face of one ram piston, the other face forces fluid out of the ram to the other ram, which in turn returns fluid to the reservoir or to the pump.
