Abstract: An electrochromic imaging apparatus utilizing electrochromic iridium oxide and a thin-film solid ionic conductor. In a transmissive cell, a first electrode, a photoconductive material layer, an electrochromic iridium oxide layer, an ionic conductive material layer and a second electrode are successively disposed on a substrate. The electrochromic iridium oxide exhibits coloration when an electric field of one polarity is applied across the first and second electrodes to record an image which is incident upon the substrate. Reversal of the polarity of the electric field across the first and second electrode causes bleaching of the electrochromic iridium oxide. In a reflective cell, a light blocking layer having a reflective surface is disposed between the photoconductive material layer and the electrochromic iridium oxide to optically separate a viewing light incident upon the second electrode from the image incident on the substrate.

Abstract: Compositions containing an organic sunscreen and particular substituted dialkyl malonates adjuvants therefor are very effective in providing broad spectrum sunscreen protection.

Abstract: Novel compositions of matter consisting of benzene sulfonate quaternary ammonium salts have been found to be possessed of very good antistatic, emollient and substantive properties. They are prepared by reacting the amide or ester with the requisite sulfonate.

Abstract: Compositions containing a benzalphthalide, i.e. benzalphthalide or a substituted benzalphthalide, are very effective broad spectrum sun screens. They are prepared by reacting substituted or unsubstituted phthalic anhydride with the corresponding substituted or unsubstituted phenyl acetic acid.

Abstract: A polling system includes a central processor and a plurality of subsystems connected in a loop to the central processor. A receive/bypass circuit in each subsystem includes a depletion mode field effect transistor having its drain and source electrodes connected in series in a bypass line at the subsystem. A control circuit is connected to a polling signal input line at each subsystem. When the subsystem has power, the control circuit routes the polling signal to a terminal device in the subsystem while establishing a conduction-inhibiting voltage at the gate electrode of the field effect transistor. When the subsystem is unpowered or out of service, a switching transistor in the control circuit isolates the terminal device from the polling signal input line. The polling signal bypasses an unpowered subsystem through the unbiased field effect transistor in the bypass line.

Abstract: A high-voltage current transformer has an external inductance element electrically connected thereto. The inductance element has a relatively low magnitude of inductance, compared with the inductance of the current transformer, to cause a substantial increase in the excitation current which significantly reduces the residual flux in the current transformer.

Abstract: An electromechanical actuator is provided which is capable of disconnecting the output shaft and the drive mechanisms in such a way that, in the event of either a rotational or translational failure during operation, the output shaft can be effectively freed in such a manner that it will not resist the motion produced by other actuators which have not failed.

Abstract: A fuel pre-vaporization system for an internal combustion engine comprising a fuel vaporization chamber having a fuel inlet and a vapor outlet. The system further comprises a magnetron for generating microwaves and a microwave absorbing heat transfer medium exposed to the magnetron output and associated with the vaporization chamber in heat communicating relation with the interior of said chamber. A vapor transfer chamber is provided in communication with the vapor outlet of the vaporization chamber for transmitting vapor from the vaporization chamber to the engine.

Abstract: Novel compositions of matter consisting of fatty halo alkanoate quaternaries of dialkylaminopropylamides have been found to be excellent emollients having surprisingly good anti-tangle and anti-static properties in hair preparations. They are prepared by reacting the dialkylaminopropylamides with fatty halo alkanoate esters.

Abstract: Novel compositions of matter consisting of amido propyl dialkyl amino beta hydroxy ethyl ammonium halides of mink oil have been found to be excellent emollients having surprisingly good hair conditioning properties. They are prepared for example by reacting either ethylene chlorohydrin or ethylene bromohydrin in a medium of water and propylene glycol, with an amide obtained by reacting, under anhydrous conditions, mink oil with either dimethylaminopropylamine or diethylaminopropylamine using an alkaline catalyst such as sodium hydroxide.

Abstract: A high voltage current transformer, and method of constructing same, including a primary winding having concentric leads, and a secondary winding on a magnetic core which is inductively linked with the primary winding. The magnetic core is a wound, two part core, with the two core parts being joined by stepped-lap joints. The secondary winding is a distributed winding having turns which are uniformly distributed about the complete magnetic circuit of the magnetic core. The conductor of the secondary winding is severed and the associated ends electrically re-connected, each time the conductor passes a stepped-lap joint.
