Abstract: A battery construction for primary cells of the type comprising a sealed flexible plastic envelope containing electrolyte and the active cell elements wherein an external electrical connection comprises a connector plate within the envelope and that connector pierces the envelope. A seal against the loss of electrolyte from the envelope through the connector aperture is achieved by locating the extension of the connector on the collector plate with portions of the face thereof surrounding it, by forming an adhesive bond between the adjacent inner face of the envelope and the collector plate surrounding the connector extenion, and by imposing external pressure on the adhesive bond by means of a pad which conforms to the envelope and imposes pressure over the bond. The pad is shown as a resilient, elastomeric, sponge sheet positioned between the cell envelope and battery casing.

Abstract: An apparatus and method for generating clock pulses to an electronically controlled glassware forming machine from the variable frequency power present in a power selsyn multiple motor drive system is disclosed. The frequency of the power present in the selsyn rotor windings is subtracted from the frequency of the power present in the selsyn stator windings to generate a difference frequency signal. The difference frequency signal has a frequency which is directly proportional to the speed of the rotating selsyn rotors. The difference frequency signal can be scaled to provide a desired number of clock pulses and reset pulses per machine cycle.

The invention involves both method and apparatus for inspecting for such defects, whereby radiant energy is directed from above to be transmitted through the sidewall as a vertical band or column while the container is rotated. A light-sensitive detector observes the sidewall for reflected light produced by the defect, energizing of the detector creating a reject signal for rejection of flawed containers.

Abstract: A short circuit proof driver and alarm circuit for a solenoid actuator in a glassware forming machine is disclosed. Power to the solenoid is switched from a power source by a VMOS enhancement mode power transistor. Under normal operating conditions, the power transistor will be operated in saturation, whereby very little voltage is dropped between the drain and the source. When a short circuit condition occurs in the solenoid or connecting cable, the power transistor will be pulled out of saturation and the amount of voltage drop will become significant. Circuitry is provided for limiting current flow through the power transistor to a value somewhat above the maximum normal load current. The components of the system are selected to operate properly in the short circuit condition, thereby preventing the accidental activation of a solenoid in the glassware forming machine.
