Title: Tissue and fluid pervious breast implant.
Inventor: OFFRAY DENISE ANN
IPC: A61F2/12
Filed: 1997-10-20
Abstract: A breast prosthesis implant (10) is disclosed comprising a generally conical bio-compatible fabric shell (11). The shell (11) is pervious to tissue growth and body fluids. The interior of the shell (11) is divided into a series of discrete chambers (14, 15, 16, 17, 18 and 19) separated by pervious fabric dividers (14', 15', 16', 17' and 18'), the chambers (14-19) containing masses of bio-compatible fibers. The fiber concentration in the chambers (14, 15) nearest the apex of the cone is less than the concentration in chambers (18, 19) progressively further from the cone apex. Preferably, the shell (11) is somewhat stretchable to permit the volume of the shell (11) to increase or decrease in accordance with the weight gain or loss of the patient.

In a froth flotation process or apparatus for carrying out such a process liquid 7 is impelled through a pipe 2 into slurry 5 below the surface 6 thereof and released to spread out into the slurry 5 and a gas is delivered through the vortex, unmixed with the liquid 7, where such liquid 7 is released into the slurry and the gas is broken up into fine bubbles 10 which rise through the slurry 5 and pick up particles to form froth. In the arrangement shown in Fig. 4, pulp 5<SP>1</SP> is contained within a receptacle 4<SP>1</SP> provided with a conical bottom 4<SP>11</SP>. Liquid is introduced tangentially into a chamber 11<SP>1</SP> through an inlet 12<SP>1</SP> and gas under pressure is introduced into the chamber 11<SP>1</SP> through a pipe 13<SP>1</SP>. The gas and liquid then pass from the chamber 11<SP>1</SP> down a pipe 3<SP>1</SP> into the pulp 5<SP>1</SP> to form fine bubbles 10<SP>1</SP> which attach themselves to particles in the pulp 5<SP>1</SP> to form a froth 14 which overflows into a trough 16. Part of the pulp 5<SP>1</SP> may be recirculated through a pipe 17, pump 18, pipe 19, inlet 12<SP>1</SP> and chamber 11<SP>1</SP>. Liquid or pulp 5<SP>1</SP> may be supplied to the receptacle 4<SP>1</SP> at 20 and tailings may be discharged through a pipe 21. Gas may be introduced into the chamber 11<SP>1</SP> with the liquid through the tangential inlet 12<SP>1</SP> and separated from the liquid within the chamber 11<SP>1</SP> due to a swirling or centrifugal action. In a further embodiment, Fig. 5 (not shown), gas is introduced through a pipe projecting upwardly into a vortex cavity formed by the liquid 7 issuing from the bottom of the pipe 2 shown in Fig. 1.

Title: Tennis racket for allowing ball spin - has strings covered with tubular sleeves slidable over limited distance
IPC: A63B51/00
Filed: 1978-03-08
Abstract: The strings (a, b) on a tennis racket are provided with tubular sleeves (g, h) such that the sleeves are able to slide on the strings over a certain distance. At the crossing points the plastic sleeves are fused together so that they are fixed relative to each other. The sleeves on the longitudinal strings are in one piece over the full length of the string, whilst the lateral sleeves (h) are in short sections so that a small gap remains between each sleeve section. When a tennis ball is hit with this type of racket, a slight cut during impact causes the strings which are in contact with the ball to be deflected. This produces ball spin, which is otherwise difficult to obtain by a moderately skilled player.
