Title: Process and apparatus for the production of optical lenses
Inventor: HAASE LOTHAR
IPC: B29D/
Filed: 1995-03-03
Abstract: In a process for the production of optical lenses, in particular contact lenses, a lens material (M) is introduced between two mould halves (1, 2). The mould halves each have a moulding surface (10, 23) and enclose a cavity (3) in the closed state of the mould. After the lens material has been introduced the two moulding surfaces are moved towards each other and the lens material is enclosed in the cavity. If necessary, the lens material enclosed in the cavity is then polymerised. The first moulding surface (10) is provided on the one mould half (1) and the other mould half (2) comprises a mould part (22) that is movable inside it with a close fit in the manner of a piston and on which the second moulding surface (23) is provided, so that by moving that mould part (22) towards the first moulding surface (10) the cavity (3) is closed. For this purpose, the two mould halves (1, 2) are first assembled, then the movable mould part (22) which has the second moulding surface (23) is moved in the direction towards the first moulding surface (10). With the mould halves assembled, the lens material (M) is introduced between the two moulding surfaces (10, 23) before the cavity (3) is closed.

Title: Anti-racking device for wood framed and other buildings
Inventor: ANDERSON RAYMOND L
IPC: E04B1/10
Filed: 1995-03-16
Abstract: In the field of structural framing, it is known to use sheathing, cross bracing, struts, and such means to endeavour resistance to racking of walls in standard framing methods. In this invention, the novel approach is to combine a means to tie the vertical and horizontal structural members together at their weakest points, "the corner". By placing the invention in the centre line of the structure, it gives maximum integrity, adds rigidity, but remains resilient and at the same time ties the frame members to each other and the foundation, leaving the faces of the structures flush for attaching sheathing and finishing products.

Patent CA-2155781-A1 (CA)
Title: Pleated blinds
Inventor: RALTON DAVID
IPC: E06B9/24
Filed: 1995-08-10
Abstract: A pleated blind is disclosed including a head rail, a bottom rail and an expandable and collapsible shade extending between them and divided up into a plurality of pleats by fold lines. A row of apertures passes through each pleat to permit passage of a supporting cord. The supporting cord consists of a central yarn and a series of equally spaced polymeric rungs. The rungs are spaced at equal intervals along the cord, the spacing between the rungs being substantially equal to the maximum distance between the head rail and the bottom rail divided by the number of pleats in the shade. In this way, the rungs, which are of sufficient length to span the sides of the apertures, will support their respective pleats and prevent the pleats from opening up too widely, thus ensuring that the pleat spacing remains substantially even.

Title: Filter media treatment of a fluid flow to remove colloidal matter
Inventor: COMSTOCK DANIEL L
IPC: B01D37/03
Filed: 1994-03-18
Abstract: Colloidal matter is removed from a fluid flow (122) by first adsorbing a coagulant (162) onto the surface of a finely divided filter media (126), and thereafter passing a colloid-containing fluid (122) through the filter media (126). The adsorbing of coagulant (162) is accomplished with the filter media (126) off line, and it is returned on-line for filtering of the fluid. After the coagulant (162) is adsorbed onto the filter media (126), it is not necessary to continue feeding coagulant during on-line operation, as the adsorbed coagulant captures the colloidal matter in the fluid (122) and retains it on the surface of the filter media (126). The captured colloidal matter is removed during back washing of the filter media (126).

Patent CA-2162940-A1 (CA)
Inventor: GOSDIN MICHAEL
IPC: F04B41/02
Filed: 1995-11-15
Abstract: The invention relates to a method for fabricating hollow plastic objects of thermoplastic material, compris-ing the following steps: 1) injecting melt into the tool cavity (1,2); b) Simultaneously and/or subsequently intro-ducing a pressurized fluid into the melt, so that the melt which has been introduced into the molding tool (1, 2) is distributed in the cavity and is pressed against the walls of the molding tool (1, 2), the pressurized fluid being conducted from a pressurized container (5) into the melt, and the pressurized container (5) being supplied with fluid by a compressor (7) which contains a drive element (6); c) allowing the molded part (8) to cool; and d) relieving the cavity of the pressure of the pressurized fluid.  According to the invention, the drive element (6) of the compressor (7) is maintained at a temporally constant power level (P) at least over the production of a large number of plastic objects.  This power level is advantageously calculated from the ratio of the work (W) which must be done by the drive element (6) in order to furnish an amount of pressur-ized fluid that is needed for a certain number of plastic objects over an associated total cycle time (T), relative to this cycle time (T).  As a result, the drive element (6) operates continuously, which results in favorable energy conditions and lower wear.
