Abstract: A lamp with an internal reflector is disclosed. The reflector includes an extension captured in the inner surface of the envelope to security position, and maintain the reflector position, without having extraneous support, bridge, or other internal fixtures to secure the reflector. The invention described reduces the need for support mechanisms, and allows the further reduction of lamp sizes for lamps having internal reflectors.

Abstract: A headband of elastic material has one or two pockets, each for receiving the barrel of a flashlight, particularly the type which permits focusing of the light beam. In accordance with the preferred construction, each flashlight pocket is formed by an overlap of two ends of headband straps, which are joined together by stitching. The stitching is at the edges, leaving an open ended pocket oriented in the forward direction.

Abstract: A method of constructing a filament support member from a single-piece preformed refractory metal wire having at least one loop protrusion formed in the wire and positioned between the ends of the wire. A section of glass tubing is positioned over and supported by the loop protrusion with a head portion of the loop extending beyond the section of tubing. Heat is applied to melt the section of tubing to form an insulating bead at the base of said loop protrusion. The head portion of the loop protrusion is then trimmed to interrupt electrical continuity in the wire and thus electrically isolate the respective ends of the wire.

Abstract: Measurement of the ionic value X of a solution of a polyelectrolyte after shearing, for instance by a rotating blade, and/or measurement of the ionic value Y of a solution of polyelectrolyte before shearing, and especially the difference between t he values X and Y, gives a useful indication of the degree of cross linking of the polyelectrolyte and so can be utilized to control the manufacture of the polyelectrolyte, for instance drying conditions, or the storage or use of the polyelectrolyte, for instance its suitability or dosage in a flocculation process.

Abstract: An aqueous organic or inorganic suspension can be coagulated and then flocculated by flowing it past a shaped body comprising a mixture of water soluble multivalent metal coagulant and a water soluble organic polymeric flocculant in the form of substantially discrete particles. The surface of the shaped body is eroded by the flowing stream to form a solution of the coagulant in which the polymeric flocculant particles are entrained, and these subsequently dissolve into the suspension.

Abstract: A hydraulic fuse or cut-off device divides fluid flow into: (i) a primary fluid stream; and (ii) a secondary fluid stream having a substantially constant, but small ratio of flow to said primary stream. The secondary stream exerts pressure on a timing piston which thereby monitors the entire flow and causes the fuse to cut-off when a predetermined volume of fluid has passed through the device. The fuse includes a regulating piston for building inlet pressure to a value sufficient to develop the power necessary to drive the timing piston. Greater simplicity of the component parts and decreased sensitivity to contamination results from the use of a small fluid orifice to control the secondary stream. This is achieved by fitting the regulating piston with an inwardly directed flange, just touching the peripheral surface of a slightly tapered, central pin--whereby the taper of the pin causes the orifice to be created as the regulating piston is caused to slide as a result of the primary fluid flow.

Abstract: An apparatus including a vehicle support, for receivably supporting the wheels of a vehicle which has pulling towers attached to the vehicle support for pulling on a part of a vehicle disposed on the vehicle support. An arm is pivotally attached to the tower at one end thereof and has an engagement attachment disposed on the other end of the arm for abutment with the other side of the vehicle. An intermediate portion of the arm, between the ends thereof, is operably attached to the tower for permitting the tower apparatus to selectively pivot the arm up and down and thereby cause the engagement attachment and the vehicle in engagement therewith to move up and down accordingly.

Abstract: The clarification of a sodium aluminate liquor in the Bayer Process, especially the liquor obtained by Kelly filter filtration of the supernatant from the primary settling stage, is improved by flocculation with a polymer of the formula CH.sub.2 .dbd.C(R.sup.1)CONHR.sup.2 NR.sup.3 R.sup.4 wherein R.sup.1 is hydrogen or methyl, R.sup.2 is straight or branched chain C.sub.2-8 alkylene having at least 2 carbon atoms in the backbone and R.sup.3 and R.sup.4 are independently selected from C.sub.1-4 alkyl.

Abstract: An improved electric lamp wherein a flexible cover holder is utilized to secure the lamp's cover means (e.g., lens) against the reflector in a sealed manner. The holder flexes during lamp operation to enable expansion and/or contraction of the cover means in such a manner that damage thereto is substantially prevented. In one example, a ceramic reflector and glass lens combination was used, with the holder comprising an annular, metallic (e.g., aluminum) rim.

Abstract: A cross linked high molecular weight polymer formed from a water soluble monomer or blend of monomers and which has IV and/or solubility and/or rheology properties indicating that it would be unsuitable for use as a flocculant can be used as a flocculant after shearing the polymeric material. The shearing may be applied to the polymeric material before addition to the suspension that is to be flocculated or can be applied to the suspensionthat is being flocculated. The shearing increases the intrinsic viscosity of the polymeric material and can improve its rheology and solubility. The polymeric material must be of high molecular weight.

Abstract: Photosensitive compositions contain a surface layer of microcapsules which influence interfacial properties.

Abstract: An electric lamp of compact, rugged design capable of high temperature operation in such applications as down lighting, display lighting, track lighting, etc. The lamp includes a ceramic reflector having therein a capsule (e.g., tungsten halogen or arc discharge) which serves as the lamp's light source. A base member of conventional external design is secured to the reflector to enable positioning of the lamp in existing socket configurations. At least one part of the capsule engages the internal surface of the reflector's central opening to assure stabilization of the capsule. The lamp further includes a cover which is capable of outward flexing during lamp operation.

Abstract: A light-emitting capsule for use in a reflector-type electric lamp utilized in such applications as display and track lighting. The capsule includes a hollow bulb portion containing a light source (coiled filament or arc) therein and an elongated sealed end including a flattened, narrow width segment and a protruding end segment. The end segment, preferably of similar configuration (cylindrical) as the bulb, is adapted for engaging the internal walls of the reflector's central opening to facilitate capsule positioning within such a reflector in both a precise and stable fashion. Additionally, the bulb portion is also capable of similar engagement to even further assure stabilized capsule orientation.

Abstract: When flocculating an aqueous suspension of suspended solids using a high molecular weight synthetic polymeric flocculant, the shear stability of the flocs is increased if the polymeric material includes polymeric particles of below 10 .mu.m dry size. The flocculated solids can therefore be subjected to shear without increasing the amount of discrete suspended solids in the aqueous medium and generally they are subjected to shear by shearing the aqueous medium containing them, either before dewatering, generally on a centrifuge, piston press or belt press, or by continuously agitating them, for instance in a chemical reaction medium. The polymeric material is generally formed by mixing into water polymeric particles made by reverse phase or emulsion polymerization in the presence of added cross linking agent. Alternatively, particles insolubilized by insoluble monomer may be used. A reverse phase dispersion of water soluble polymer may be used if the particles remain undissolved, e.g.

Abstract: An electrical firing arrangement for the sequential firing of a plurality of mortars stacked in end-to-end relationship within a single launching barrel. The firing arrangement comprises a pulse generator for producing mortar firing pulses and a circuit for applying these pulses to an electro-magnetic stepping switch which applies the pulses in turn over pairs of wires to igniters of the respective mortars as the stepping switch is stepped from one position to the next. The stepping switch comprises normally-open contacts which close when an operating coil is effectively energized by a firing pulse and switch wipers move out of engagement with one pair of associated contacts on the stepping switch towards the next pair of associated contacts on the same switch.

Abstract: A marksmanship training system has been developed which depends upon the mal levels of infrared radiation emitted from warm-blooded animals, such as humans. An infrared detector is mounted upon a simulated rifle or unloaded real rifle, or other weapon. This detector is mounted with IR lenses in such a way that a positive indication is given when the rifle is pointed at a suitable infrared emitting animal target. A second detector indicates when the trigger of the weapon is pulled. If a trigger pull is detected at a time when an animal infrared signal is present, the system generates an electronic pulse indicating that a target hit has occurred. This pulse may be used to drive a visible or audible signaling device to inform the user of success.
