Abstract: A process for producing three-dimensional, mirrored acrylic products using forming techniques eliminates micro-fracturing of a vacuum deposited reflective metal coating by preshrinking a sheet of acrylic before the sheet is mirrorized and formed into the desired three-dimensional shape. Preshrinking is accomplished by heating the sheet to forming temperature and allowing the heated sheet to cool at room temperature before the sheet is formed. Deposition of the metallic reflective coating is performed after the preshrinking step.

Abstract: A home security and garage door operator system includes a gas sensor for detecting the level of toxic gas in the garage. When the gas level exceeds a predetermined threshold the garage door is automatically opened. Lock out circuitry is provided for preventing the door from being accidentally closed as long as the gas sensor detects an excessive level of toxic gas in the garage. A two button transmitter is used to sequentially close the garage door and set a security alarm subsystem. Warning devices are activated if the security alarm is attempted to be set without the garage door and windows in the home being closed. Once the security alarm has been set, the lock out circuitry also disables the garage door motor control circuitry until the security alarm is first deactivated. The transmitter generates a digital pulse train according to a preselected code, with the operation of the dual buttons changing the state of a particular control bit in the pulse train.

Abstract: An electronic multiple-setback thermostat for residential and commercial use includes an internal clock having a week-long cycle. The thermostat is programmed by the operator, usually manually actuable input devices, to control the furnace/air conditioning system to achieve a schedule of temperatures over the weekly period by simply inputting the temperature desired to be attained at the time of entry. Each temperature entry may be programmed to reoccur on a daily basis or to modify the program on a once-a-week basis. The thermostat employs an internal clock which controls memory addresses so that each memory location is representative of a short time period during the weekly cycle. A desired temperature signal is entered in a memory location determined by the clock state at the time of entry and is read out to the control system each time that time state reoccurs.

Abstract: Apparatus is disclosed for measuring the electrochemical activity of a liquid, for example, the hydrogen ion activity or pH value of blood. A disposable cartridge includes spaced indicating and reference electrodes which develop electrical properties as a function of the electrochemical activity. The cartridge carries a capsule containing an electrolyte solution. A machine for measuring the electrochemical activity includes a socket in a pivoting door for receiving the cartridge. When the door is pivoted into a closed position, the capsule is automatically crushed thereby covering the electrodes with the solution. The breaking of the capsule triggers an electronic measurement of the resultant electrical properties that develop between the two electrodes. This calibration factor is stored and used to compute the electrochemical characteristics of the sample when it is introduced into the cartridge to cover the indicating electrode.
