Title: Improvements in electric circuit breakers
IPC: A23L21/12
Filed: 1957-06-27
Abstract: 812,101. High-tension switches; arcing- preventing in switches; protective cut-out arrangements. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. June 27, 1957 [June 28. 1956], No. 20321/57. Class 38 (5). An A.C. circuit-breaker with main contacts 3, 4 and parallel auxiliary contacts 5, 6 is provided with an impulse transmitter 8 synchronized with the current to be interrupted, the transmitter applying a first pulse to an operating circuit 11 to close the auxiliary contacts 5, 6 and then open the main contacts 3, 4 shortly before a current zero, and a second pulse to another operating circuit 12 to reopen the auxiliary contacts before this current zero, but after the opening of the main contacts. The second pulse may also effect the opening of a disconnecting switch 2, the main contacts then reclosing. The main contacts may be housed in an enclosure 22 filled with gas under pressure and the auxiliary contacts may operate under a high vacuum. The transmitter 8 may be controlled by a current transformer 7 or from a shunt in the controlled circuit 1, and may be arranged to produce the pulses only if the rate of increase of the current at the start of a half cycle has a predetermined sense and a value greater than a desired minimum, but less than a predetermined maximum. The transmitter 8 may also be controlled remotely by an hydraulic pulse generator 16 connected to the transmitter 8 through an oil-filled insulating pipe 17. The generator 16 is controlled by an " opening " button 18 and a closing button 19, the operation of the latter causing a pulse to be applied to a circuit 13 to effect the closing of the switch 2.

Title: Improvements in or relating to counters for record-card-controlled statistical machines
Filed: 1923-08-09
Abstract: 214,571. British Tabulating Machine Co., Ltd., (Assignees of Ford, E. A.). April 17, 1923, [Convention date]. Statistical machinas; zeroizing- mechanism.-Two counters driven in common are employed and arrangements are made whereby one only or both may be zeroized. The recordcard, say in a Hollerith machine, controls the rotation of the various gear wheels 49 mounted on the driving- shaft 45 by means of electromagnetically operated clutches in the usual way and these wheels gear with corresponding spur-wheels arranged on two shafts 46, 47 and secured to numeral wheels 53. These two sets of wheels 53 constitute two separate counters actuated in common from the gear wheels 49 and the lower counter or both counters may be zeroized at will by the rotation of a common re-setting shaft. The numeral wheels are zeroized by means of pick-up pawls which are mounted on the transfer discs secured to each wheel and are adapted to be engaged and moved round by grooves in the shafts 46, 47 when these are rotated. In order to enable one counter only to be zeroized the drive from the reset shaft to shaft 47 includes a gear wheel 69 connected with shaft 47 through a clutch 70, Fig. 6 thrown in or out by a lever 73 rocked by a cam 72 on a hand-lever 71. The zero position of the shafts 46, 47 is defined by a spring- controlled detent 75 in co-operation with a notched disc 76 fixed on shaft 46. The detent pawls 59 engaging pins of notched discs on the numeral wheels tend to prevent overthrow and the numeral wheels are also braked bv shoes 93 supported by a lever 92 rocked to apply the brakes by means including a frame 91 operated from the reset shaft. The transfer' parts of the lower counter are held up during zeroizing by bail 91 and those of the upper counter by a projecting arm 94 moving with lever 71. Overthrow in ordinary adding actuation is prevented by providing the brake lever 92 with a link operated at the end of each cycle by a cam on the transfer shaft 42.

Abstract: 1,161,353. Sheet forming. O. HÍFLIGER and R. KARG, [trading as HÍFLIGER & KARG]. 5 May, 1967 [12 May, 1966], No. 20904/67. Heading BSA. The temperature of a vacuum forming drum is controlled by an internal heat exchange medium the temperature of which is monitored by a device which controls the means for heating and cooling the medium. In the embodiment shown, coolant is pumped by pump 2, from a storage vessel 1 through a pipe 5 into drum 8, and is returned via pipe 6 air cooler 3, and pipe 7 to the storage vessel. The temperature of the coolant in the storage vessel is detected by means 9 and 10, each of which is connected to a measuring device 11 and 12 respectively, which devices control the operation of blower motor 36 and heater 35 respectively. In operation, prior to starting the machine, external heater 37 and the heater 35 are switched on to raise the drum to the desired temperature. During operation, when the temperature rises above the lower temperature of a desired range the device 12 is operated to deactuate the heater 35. If the temperature of the coolant continues to rise and exceeds the upper temperature of said desired range, the device 11 is operated to start blower motor 36, and, as the temperature drops back to said upper temperature, the device is operated to stop the blower motor. In the event of the temperature continuing to drop past said lower temperature the device 12 will be operated to re-actuate the heater 35 thus bringing the coolant temperature back within the desired range.
