Title: Sodium-free heparin salts - by cation exchange of sodium salts, anticoagulants without side-effects
IPC: C08B37/10
Filed: 1973-04-13
Abstract: Single-metal salts of heparin with metals other than Na or mixed heparin salts are prepd. by contacting a suitable single-metal salt (esp. Na salt) with a metal salt so as to cause cation exchange, and then in a second stage, the ions released in this exchange process are removed and the resultant salt contacted with the exchanging metal again, opt. this treatment cycle is repeated until cation exchange is essentially complete. Ions released may be removed by dialysis and/or pptn. with aq. alcohol. Mixed salts and Ca salts contg. practically no Na are new cpds; esp. pref. are Ca salts contg. 10.3-10.6 wt.% ca and 0.1 wt.% Na. These salts do not cause skin bleeding or haematosis as does the Na salt.

Title: Leaf spring mounted in sole of shoe - is rivetted to sole to hold inner sole in contact with foot
IPC: A43B23/22
Filed: 1976-02-02
Abstract: A shoe is fitted with a curved leaf spring (5) which is elastically deformable, and which is fixed under the supple inner sole.

Title: Shell-and-tube heat exchanger partic. for evapn. - has partitions defining inlet, reheat, evapn. and distribution spaces and flow-directing tubes
Inventor: MARIE GERARD
IPC: F28F9/22
Filed: 1976-02-09
Abstract: A vertical heat exchanger, partic. for the evapn. of a sec. fluid by heat transferred from a prim. fluid, incorporates tubes through which the prim. fluid flows downwards and a shell with top and bottom and plates and three intermediate horizontal partitions. The partitions and the end plates define, from the bottom upwards, an inlet space and reheating, evapn. and distribution spaces for the sec. fluid. The tubes, except one, are surrounded by outer tubes in the reheating space. The outer tubes are connected at their upper ends into the reheating space, near the second partition. The other tube is surrounded by an outer tube which opens into the reheating space at its lower end and into the distribution space at its upper end. The third partition has holes around the first set of tubes, which allow the fluid to flow downwards along the outer wall of the tubes. The shell has a fluid inlet and a fluid outlet in the inlet space and the evapn. space respectively. The arrangement gives an improved thermo-dynamic efficiency, by the reheater being put at the lower part of the evaporator, i.e. in the zone near to the outlet of the prim. fluid, and the sec. fluid circulating countercurrently.

Title: Guide roll track for continuous casting plant - using packing pieces and wedges for rapid adjustment of roll gap
Inventor: LIBOSSART HENRY
IPC: B22D11/128
Filed: 1976-04-05
Abstract: Guide roll track for continuous casting plants, using a chassis contg. two parallel rows of rolls. The gap between the rolls can be continuous adjusted by using packing pieces between the roll chocks and between the chocks and the chassis. In one pref. design, wedges are driven by turning a threaded bolt to a clamp a stack of packing pieces forming the roll gap, whereas in an alternative design a hydraulic screw is used to clamp the packing pieces. The gap between the rolls, which forms the thickness of the cast billet or slab, can very easily be adjusted to compensate for roll wear and packing pieces are easily added or removed to obtain the different thicknesses required for various prods.
