Abstract: An enclosure for an electrical terminal block includes a housing having a back wall and projecting side walls which form a bounded chamber. The chamber accommodates an electrical terminal block. A cover is hingedly attached to the housing and may be locked thereto to protect the terminal block housed therein. The cover and the housing are attached in such a manner so that if the cover is not properly locked to the housing, the cover will pop open providing a visual indication to the installer that the cover has not been locked properly to the housing.

Abstract: A method for terminating an electrical conductor, comprises an outset step of defining a housing having an open end and a closed end and at least one passage therethrough for entry of the conductor into the housing to permit a termination end of the conductor to be resident interiorly in the housing. Next, the housing passage is closed and the housing is disposed with the housing open end vertically above the housing closed end. With the housing so disposed, sealant gel is introduced in liquid state interiorly of the housing. While the sealant gel is in the liquid state, there is secured with the housing, through the housing open end, apparatus for subsequent use in terminating the conductor, Upon transition of the sealant gel to a cured state, the housing passage is opened. To complete the conductor terminating method, at the installation site, the conductor is inserted into the housing passage and into registry with the terminating apparatus.

Abstract: An electrical connector for use as a telephone plug or jack is assembled without need of special tooling and comprises a housing for receiving an insert member. The insert member supports a plurality of contacts thereon, each contact having a first end for external connection to the contacts of another jack or plug and a second end portion of insulation-displacing type. A conductor support element secures telephone cable conductors therein and is engaged with the housing to place the conductors in insulation-displaced engagement with the contact second end portions. A twenty-five pair telephone connector utilizing a modified version of the jack includes, in its preferred form, a base having first and second pluralities of compartments separated by a fold section. The fold section defines a channel for receipt of conductors of a multiconductor telephone cable. The folded base places the jack housings in abutting relation for retention therein, securement means holding such base in its closed, folded condition.

Abstract: A solar energy collection and utilization storage system is constructed by using a lenticulated transparent element closed at the back to form channels which are used to carry an energy storage fluid. The lenticulations are designed as light trapping surfaces so that virtually all of the energy from the sun at any time of day falling on the sheet is trapped by the lenticulations and transferred to an energy storage fluid which is in the passages formed by the lenticulations and the back cover panel. The rate of flow through the solar collector panel is controlled by a thermostatic valve element which opens the flow when the fluid reaches a predetermined temperature. The energy storage fluid is a dispersion of a crystalline polymer in a heat transfer fluid which has the capacity of storing heat by a latent heat of crystallization as well as by sensible heat.

Abstract: A micro-capsular material for use as a photographic reproducing medium includes a plurality of micro-capsules distributed over a given surface. Each of the capsules is formed with a mantle of light transmissive material. The mantles may be clear or colored and are advantageously transparent. The contents of each of the capsules includes a photoconductive material as well as a color progenitor or precursor material. Simultaneous exposure of the capsular material to light and high frequency electrical energy causes rupture of the capsule mantles and release of the capsular contents. When an image is focused by a lens onto the surface, selected ones of said capsules are ruptured to thereby result in a reproduction of the image. Dispersing micro-capsules having different color progenitor materials makes possible color photography when means are provided for selectively directing only those component of colored light onto the micro-capsules having corresponding color progenitor materials.

Abstract: A magnetizable layer is initially magnetized and selected portions thereof are demagnetized by an optical imaging system. In one embodiment, an image to be reproduced is projected through a transparent electrically conductive electrode which is brought into contact with a photoconductive matrix through which is dispersed magnetizable particles. Changes in resistivity of the photoconductive matrix causes a current density distribution, which corresponds to the image intensity distribution, to flow transversely from the transparent electrode through the photoconductive matrix to a support electrode on which the matrix is fixed when a potential is applied between the transparent and support electrodes. The current distribution results in corresponding magnetic fields which modify or "erase" selected portions of the initially magnetized layer.
