Title: Improvements in or relating to the conditioning of moulding sand or the like
IPC: B22C5/08
Filed: 1945-06-07
Abstract: 593,563. Mixing-appliances. HARPER & CO., Ltd., J., and HINKS, B. June 7, 1945, No. 14328. [Class 86] [Also in Group XIX] In order to determine the moisture-content of moulding sand after mixing it with water, it is passed automatically through apparatus which estimates said content by the flow of electric current through the moistened sand. The moistened sand 3 is fed from conditioning apparatus to the moulders by a belt 1 which passes below a spreader 4 and rubber flaps 5 to produce a strip of sand of definite width and thickness. Rollers 2 carried by an insulated frame 7, connected by a link 8 to the fixed support S, rest on the sand strip. The rollers are connected in an electric circuit with a meter calibrated to indicate moisture content. This circuit may operate a motorised valve through a relay to regulate the rate of flow of the water mixed with the sand. In one construction, the moving coil ammeter 13, Fig. 3, carries a shutter to control the light from a lamp 10 falling on a photo-electric cell 11 which controls the current to a solenoid-operated valve 12 controlling the flow of water to the conditioning apparatus. Reference has been directed by the Comptroller to Specification 600,210.

Title: Improvements in or relating to automatic telephone plants
IPC: H04Q3/00
Filed: 1956-05-09
Abstract: 785,523. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 9,1956 [May 18, 1955], No. 14491/56. Class 40 (4). In a system employing cross-bar switches in which the calling and called lines become connected in parallel to a common circuit which supplies ringing current, the arrangement is such that the ringing current is prevented from passing to the calling line. A 2-digit exchange is described in which a calling line is connected over a cross-bar switch RS to an idle register REG, and in due course a marker M controls the connection of the calling and called lines to a common circuit N1. The line relays LR1 &c. of each tens group are provided with a chain-locking circuit such that only one can remain operative at a time. The operative line relay, for example LR1, connects the calling line L1 over a common line a10, b10 to a cross-bar switch RS and locks in series with select magnet S11. Relay VR1, for example, corresponding to an idle register REG operates in series with relay RR4 therein, and the latter connects up operating magnet BR1 to extend the calling line to the register, in which line relay RR2 energizes, followed by guard relay RR3. The caller receives dialling tone and the dialled digits are recorded on switches RM. Relay RR7 now operates to appropriate the marker M and over r3 connects up T10 to identify the calling line. Guard relay RR3 is disconnected and the connection is set up during its release time. The marker M seizes an idle common circuit N1 and connects up the corresponding select magnet S29 in the crossbar switch GV10. It also seizes an idle-link K10 and connects up relay KR1 which energizes operating magnet BK to connect K10 to the circuit N1. At the same time the calling line L1 is connected to K10 by the operation of magnets S9, B1 of the switch SL1. The called line is tested and if it is free the marker seizes a second link K14 (not shown) which becones connected to the called line and to the circuit N1, and the register REG and marker M release. Relay KR1 in K10 now holds over the calling line L1 in series with NR2 in N1, but relay KR1 in K14 cannot hold. Thus, when the called line which is connected to relays NR2, NR1 receives ringing current over t5, this current is withheld from the calling line by the operation of KR1 in K10. Ringing tone is fed to the calling line from t6 however. Upon reply NR1 pulls up and disconnects NR2, with the result that KR2 energizes in K10 to act as a feed relay and disconnects KR1. The called line is fed over NR3. In one modification, Fig. 4 (not shown), both lines are fed from the link attached to the calling line and in another, Fig. 5 (not shown), both lines are fed from the common circuit.
