Abstract: Abstract:    For producing the bone substitute material from collagen and hydroxyl apatite, an aqueous solution of clean collagen is mixed with a cross-linking agent causing only a partial cross-linking, and the mixture is lyophilized.  The quantity of the cross-linking agent is chosen such that the collagen retains its resorbability and its absorptivity vis-a-vis bodily fluids, the material further showing no undesirable side effects.  Preferably less than 1% in weight of formaldehyde, one of the preferred cross-linking agents, is added, with reference to the dry weight of collagen, and sintered apatite grains with a diameter of 50-300  m are used.  Such a bone substitute material is stronger and less tearable as previsouly known materials and insures a good promotion of the growth of own bone tissue and the substitution by it.

Abstract: Abstract of the Disclosure A bushing controller circuit for regulating the current flow through a fiber glass bushing to thereby control the temperature or the molten glass being drawn into fibers is disclosed.  The bushing temperature is measured by a plurality of thermocouples which produce an average temperature reading that is used to control the power fed to the bushing.  The bushing controller circuit is a three-terminal device connected across two sections of the bushing to regulate relative current flow in the two sections, in order to control the amount of fiber produced by each section.  The bushing controller circuit includes a pair of timing circuits which operate in response to the polarity and magnitude of a control signal, produced at a remote control panel, to control the conductivity of a corresponding pair of current control devices connected across respective sections of the bushing.  A reset circuit produces a signal corresponding to the zero crossing of the input AC power to synchronize the timing circuits.

Abstract: - ABSTRACT -A semiconductor structure and methods for making it, for use in opto-electronic devices, employs only MOVPE growth steps.    The structure is based on a mesa having substantially non-reentrant sides.  To make it, an initial semiconductor structure is produced which comprises a substrate with a mesa thereon, the mesa having a self-aligned, central stripe 16 of metal organic vapour phase growth suppressing material on its uppermost surface 15.  Burying layers 8, 9 are then grown by MOVPE an either side of the mesa, the stripe removed, and covering layers 10, 11 grown over the mesa and adjoining regions of the burying layers 8, 9.  To make an opto-electronic device, a silica window 18 can be formed on the uppermost surface 20 of the covering layers 10, 11 and contacts 13, 14, 19 provided through the window 18 and to the remote face of the substrate.  Two methods of making the initial semiconductor structure are described.    Devices such as optical detectors and waveguides can be made using methods according to the invention. Particularly importantly, semiconductor lasers which will operate in a single transverse mode can be made.
