Abstract: 970,983. Skid rails. SPENCER-BONECOURT-CLARKSON Ltd. April 25, 1961 [April 26, 1960], No. 14525/60. Heading F4B. Skid tubes 10 for supporting ingots in a furnace rest in saddles 12 on transverse support members 11. Below each saddle 12, the support 11 is welded to a pillar 13 with an annular toggle 17, Fig. 4, inside it so that coolant can flow up the baffle tube 17 and down the annular space of each pillar 13 of one transverse support 11 in series, and then through the support 11. The supports 11 are longitudinally spaced within the furnace, and the supports 11 and their corresponding pillars are connected in parallel between headers 27, 28, and the skid tubes 10 are connected between the headers 27, 28. Bleed passages 26a, 26b, Fig. 4, through the walls of the support tube 11 prevent steam or gas accumulating in the turning space at the top of each pillar. The diameter of the pillars 13 and their internal baffles 17 vary with the height of the pillars so that the rigidity and coolant flow of the pillars is substantially constant.

Title: Battery charging control circuit
IPC: H02J7/00
Filed: 1975-04-10
Abstract: 1509567 Battery charging systems GENERAL ELECTRIC CO 10 April 1975 [11 April 1974] 14797/75 Heading H2H A battery charging system is provided with means whereby the battery charging process is controlled in accordance with the temperature of the battery during charging and with the ambient temperature in order that the battery may not be overcharged and damaged. With one battery B connected in the battery pack the operational amplifiers OA1-OA4 in the output circuit are so controlled that the output of amplifier OA3 is low with the result that no gate signal is provided for a thyristor SCR which remains non-conductive, the small current flowing through resistor R1 going to earth through resistors R2, R5, R6. When a battery B is placed in the battery pack to be charged and the temperature of such battery is below the ambient temperature sensed by a temperature sensitive resistor RAT the output of amplifier OA3 remains low, the only charging current then being received by the battery B is a trickle charge current by way of the resistors R1, R2. This current causes the battery to warm up until its temperature, sensed by a temperature sensitive resistor RBT, approaches the ambient temperature when the amplifiers OA1-OA4 are controlled such that the output of amplifier OA3 becomes high so providing a gate signal to turn on thyristor SCR so providing the battery B with a high rate charging current. When the temperature of the battery rises to a value a predetermined figure above the ambient temperature, the output of amplifier OA3, after a time delay determined by resistors R13, R14 and a capacitor C3, goes low whereby thyristor SCR turns off to terminate the high rate charging of the battery which then continues to receive a trickle charge via resistors R1, R2. Operational amplifier OA4 serves as a memory device ensuring that once the high rate charging of a battery has been terminated it cannot receive a further charge at a high rate. Operational amplifier OA2 serves as a resetting device to reset the output circuit when a charged battery is removed from the battery pack. A capacitor C2 prevents premature resetting of the output circuit.
