Abstract: An alpha-halocarbo aromatic monomer or comonomer and/or an allyl halide monomer or comonomer can be reacted with aluminum or an aluminum-containing catalyst to form a polymer.

Abstract: Sensor switch includes a compromisable mechanical restrainer and a biased member. Before compromise, the restrainer can hold the biased member in a first position. When contacted with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased member can assume a second position different from the first position. Monitoring a sample for a target chemical and/or composition can be carried out with the sensor switch.

Abstract: An optical bench 10 is cast from a single piece of material and provided with a number of optical component supports 14 which extend upwardly from a base 12. The optical component supports 14 are integral with the base 12, increasing their rigidity. The bench 10 may be cast with additional material in strategic areas to allow for future optimization of the bench 10—for example, the mounting of specific optical components throughout the bench 10. Further, the bench 10 may be provided with regions 24, 26, and 28 of varying rigidity by placing support struts 68 closer together in areas where greater rigidity is required. Apertures 30 may be provided in the bench 10 to enable the routing of conduits through the bench 10.

Abstract: An optic cell 20 for use in the cavity of a high-power laser comprises an optic housing 22 which defines a first laser beam aperture 26. An optic element 32 such as a mirror or lens is disposed within the optic housing. A first indium layer 30 is between and in abutting contact with the optic housing and the optic element. An optic cover 40 defines a second laser beam aperture 46 therethrough substantially in alignment with the first laser beam aperture to form a window 47 of the optic element through which a laser beam passes. A second indium layer 48 is between and in abutting contact with the optic element and the optic cover. The optic housing and the optic cover are typically formed of aluminum or copper to passively cool the optic element.
