Abstract: An Automatic fluid component Shut Off System which automatically shuts off the flow of one component in a plural component system when the pressure in another component falls below a predetermined amount. The system is comprised of pneumatically operated sources of fluid components such as a catalyst and a resin which are mixed as they are sprayed on an article. The automatic shut off system is comprised of a pressure sensing valve which is connected to one of the components to provide a pressure control point and controls the supply of air to an air operated servo valve controlling the flow of the other fluid component. The pressure control point is established by adjusting an air pressure regulator connected in series with the pressure sensing valve.

Abstract: A vehicle protective cover and alarm system therefor wherein the cover is of a design and configuration to at least enshroud the major body portion of the vehicle, and wherein at least two sensors are placed in opposed relationship to each of the inside surfaces of the cover and being coupled to an electrical system which upon movement of the cover will energize the system to produce an alarm signal.

Abstract: A magneto-optical device which is responsive to magnetic fields by means of a Tyndall Effect in a particular direction exhibited by aligned magnetic colloidal particles suspended in an illuminated liquid medium. The liquid medium is contained in a transparent vessel and has magnetic particles in a very low density, such that the liquid is substantially transparent to the naked eye. A light source is positioned to illuminate the liquid medium and a light-sensing device or photocell is positioned to receive light scattered by the magnetic particles. The light-sensing device is positioned at a predetermined angle from the paraxial direction of the light source. All colloidal solutions, when illuminated by a beam of light, exhibit the Tyndall Effect, i.e. a visible scattering of light by the colloidal particles.

Abstract: This application discloses a unilimb device of universal application to different types of breathing systems. The device comprises two gas carrying tubes, one within the other, the corresponding ends of the tubes being within two common terminal elements. One of the terminal elements provides for two separate passages, each being connectable, one to a source of gas, and the other for disposition of the expiratory gases. The other terminal element includes a nozzle end for connection to the inlet for the patient's respiratory system, with the opposite end serving to receive the other ends of the two flexible tubes and to provide short passages to the nozzle to minimize dead air space. Provision may be made for telescoping each terminal element, and the inlet element may be provided with a member for extending or adapting it to different breathing systems.

Abstract: A selectively mountable cold control device of the type utilized by servicemen for effectuating temporary repairs wherein the device employs alternative mounting means. In the first instance, where the cold control service is to be of a temporary nature, a pair of suction cup mounting members are utilized so as to retain the cold control device in operative relationship with the appliance with which it is used. Alternatively, where the replacement is to be of a permanent or quasipermanent nature, a singular grappling hook mounting member is utilized instead of the suction cup members. The housing of the cold control device is so configured so as to allow selection of either mode of mounting the cold control device with refrigerators, coolers and similar such appliances.

Abstract: A wall panel construction comprising prefinished wall panels of fire resistive material, such as gypsum board, wherein the opposed vertical edges have secured thereto lateral edge members of particular configuration. Initially, the lateral edge members have a flaring configuration exteriorly of the plane of the finished surface of said panels, wherein a filler is applied to provide about planar continuity between the outwardly flaring surface of the lateral edge member and the eventually finished surface of the panel member. Thereafter, finishing by sanding and squaring produces a trued panel to which is applied to decorative coating to produce a finished panel member. Texturized paint or wall covering may be laminated or adhesively secured to the entire exposed finished surface of the panel. Unsecured flaps of the wall covering may also be provided.
