Title: Process for hydroxylating hydrophobic polymer surfaces
IPC: C08J7/00
Filed: 1990-01-12
Abstract: Process for treating hydrophobic polymer surfaces to form hydroxyl moieties thereon comprises ozonating the surface of said hydrophobic polymer to form hydroperoxy groups thereon, and then irradiating said ozonated surface with ultraviolet light or exposing to heat to convert the hydroperoxy groups to hydroxyl moieties in the presence of a hydrogen donor. Such hydroxylated surfaces possess hydrophilic properties and can undergo the chemical reactions characteristic for hydroxyl groups. Polymers so modified are useful in biomedical devices, semipermeable membranes, films, fibers and especially contact lenses.

Title: Intramedullary and seal for cement pressurization
IPC: A61F2/46
Filed: 1983-04-28
Abstract: A novel cannula is disclosed for use in the application of bone cement to the prepared intramedullary canal of a bone prior to the cementation of a surgical implant therein. The novel cannula comprises a hollow tube adapted to slidingly receive the nozzle of a bone cement extruder, an inflatable cuff surrounding the tube, and means to inflate the cuff. In operation, the inflated cuff forms a seal against the wall of the intramedullary canal, thereby preventing escape of cement through the open end of the prepared canal and insuring that the applied cement is properly pressurized within the canal. As a result, a highly secure cementation of the surgical implant within the intramedullary canal is achieved.

Filed: 1986-05-20
Abstract: A process for the production of silicon in a low-shaft electric furnace, in which raw-material blanks are first formed which contain fine-grain silicon dioxide, e.g. in the form of sand, and carbon in excess in respect of the reduction to silicon carbide and the raw-material blanks are introduced into the low-shaft furnance as a charge in mixture with silicon dioxide in lump form. The silicon dioxide in the raw-material moldings is reduced to silicon carbide in an upper part of the low-shaft electric furnace at a temperature of below 1600 DEG C. and coke structure agglomerates are formed from the excess carbon of the raw-material moldings. In a lower part of the low-shaft electric furnace, the silicon dioxide in lump form, is reduced to silicon with silicon carbide and carbon from the coke structure agglomerates at a temperature of above 1600 DEG C., preferably from 1800 DEG to 200 DEG C. The raw-material moldings are formed with bituminous binder containing a fine-particle silica powder. The silicon carbon reduction results in coke structure agglomerates having a very large internal carbon area in accordance with the internal area and percentage proportion of silica powder in the raw-material moldings. The silicon dioxide and gaseous silicon monoxide are reduced with the coke structure agglomerates having the increased internal area.

Abstract: 1,191,391. Control of D.C. motors. LANSING BAGNALL Ltd. 8 Jan., 1969 [9 Jan., 1968], No. 1304/68. Heading H2J. [Also in Division G3] A D.C. motor is energized by pulses which are initiated when the armature current is below an adjustable predetermined value, as detected by an arrangement coupled to a voltage divider, part of which comprises an element whose impedance varies according to magnetic flux through it, the flux being produced by a conductor carrying the armature current. The element consists of a Hall device MR1 and a winding 11 for the current; assuming this is already flowing, when it is high enough to cause a transistor TR1 to conduct capacitor C4 is charged until its voltage is sufficient to cause conduction of further transistors TR4, TR5 to thereby trigger a thyristor TH2 and so produce a triggering pulse for a " turn off " thyristor (22, Fig. 1, not shown) in the motor circuit. This terminates a pulse and the armature current decays through a flywheel diode until the impedance of the Hall device drops sufficiently for TR1 to turn off; this allows a transistor TR2 to turn on to trigger a thyristor TH1 which in turn triggers an " on " thyristor (17) in the motor circuit and so start a new pulse and hence repeat the cycle. The time constant of C4 determines the minimum pulse length. The effective value of the armature current, and hence the motor speed, is varied either by a bias signal in a winding 31, by movement of a permanent magnet 33, by varying the otherwise constant voltage (which may be direct or alternating) applied to the Hall device by making resistor R2 adjustable, or by varying the threshold level of TR1. The motor is a series machine having separate forward and reverse field windings and in Fig. 3 (not shown) separate control circuits are provided for each direction, with an interlocking cross-connection.

Particles undergo de-agglomeration and intense mixing in the zone of the curtain. Fluid from the slit 16 together with any particles entrained thereby then attaches itself to the surface 17 whereby it is guided into a second flow path 21 and the entrained particles art deposited in a collector 22. Particles having sufficient momentum at the end of the first flow path may pass through the curtain and fall into a collector 27; or if their momentum is greater still may be entrained by fluid issuing from an annular slit 26, which attaches itself to a surface 68, 24 and conveys the particles through a conduit 25 to a further collector (not depicted). The widths of the slits 37, 16, 26 are screw-threadedly adjustable (Figs 2 and 3, not shown) and the assembly consisting of nozzle assembly 15 and arm 95, (together with conduit 25 and collector 27) may be axially adjusted by crank 98 to position slit 16 in relation to the flow attachment surface 17.
