FORMING OF TETRABASIC LEAD SULFATE BATTERY ELECTRODES A method of forming battery plates or electrodes from tetrabasic lead sulfate includes the step of adding a lead peroxide such as lead dioxide in powdered form to the tetrabasic lead sulfate for making the paste to be applied to the plate or electrode supporting grids. The addition of this lead peroxide allows forming the plates or electrodes i...

A control unit is provided with a memory unit for storing data representative of errors occurring in the system, as well as the order in which sequential errors occurred and the number of occurrences of the errors. An error "history" may be displayed from these data, to assist in pinpointing the cause of the trouble.

A data processing apparatus has a central processing unit. The CPU causes a memory to store for example input sales data in units of department sales and other items. When a power supply is turned off, a battery supplies back-up power supply voltage to the memory to retain the storage contents of the memory. When the output voltage from the battery is decreased to a value which disables back-up of...

A differential lock control system includes an hydraulically-operated differential lock operated by a solenoid valve. Energization of the solenoid valve is controlled by a circuit which includes a normally open latching relay and series-connected switches which open and unlock the differential in response to sensed vehicle speed and brake application. The differential may be locked by closing a no...

A process for producing shaped articles having improved surfaces, characterized by subjecting a shaped article of a polymer derived from a monomeric material comprising an acrylate and/or methacrylate to at least one of a hot water treatment, an aqueous alkali solution treatment and an aqueous acid solution treatment. Shaped articles obtained by this process have an advantage that when the surface...
