Title: Improvements in transportation signal system
IPC: B61L3/22
Filed: 1963-10-25
Abstract: 1,019,744. Automatic train control. S. H. BINGHAM. Oct. 25, 1963 [Oct. 31, 1962], No. 42206/63. Heading B7N. In an automatic train control system in which the train is controlled by signalling current flowing in block defining loop conductors positioned adjacent the track, trainoperated contactors are positioned at intervals throughout each block section which when actuated by a train operate associated means for short-circuiting the loop whereby the transmission of signals to a following train if it enters the block is prevented. Block TB2 of track 10 for a monorail vehicle is provided with trainoperated contacts 2-10 to 2-4C positioned less than a train length apart and a block defining loop 2BC. On entry of a train, contactor 2-1C is operated and releases repeater relay 2-1CP, contact 2-1CP2 of the relay opens to release relay 2T which is then retained in the release position by the operation of successive contacts until the train leaves the block. Relay 2T acts as a track relay and prevents at its contacts 2T6 and 2T7 the application of signalling current to the loop of the preceding block. Operation of contactor 2-2C releases relay 2-2CP which at its contact 2-2CP1 opens the hold circuit of relay 2-2CR which subsequently releases and by means of its contacts 2-2CR3 and 2-2CR4 places a short-circuit across loop 2BC. Subsequent operation of the succeeding contactors in the block place further shortcircuits across the signalling loop. When the train has left the block, relay 2T picks up and at its contacts 2T6 and 2T7 applies slow-speed signalling current B to the signalling loop of block TB1. When the train has partially completed its journey through the following block TB3 relay 3J is picked up for a short period and restores the CR relays of block 2TB to their normally energized state and when the train has left block TB3 its track relay picks up to apply slow-speed signals to loop 2BC of block TB2 and by picking up relay 2H applies fast speed signals to block TB1.

In an embodiment, an N-type Si body 2 has a P-type pocket 8 formed therein (Fig. 1b) by ion implantation beneath a screening oxide layer 6. The screening layer 6 and the oxide layer 4 are removed and replaced by an overall oxide layer (10, Fig. 1c, not shown) causing drive-in of the P-type pocket 8. An N-type layer 12 of phosphorus is made by ion implantation after pocket 8 has been covered with photo-resist. The N- and the P-type regions (8, 12) are drivenin further by heating. A thick layer of oxide 14 is formed on the top surface and windows formed for the source, drain and other connections (Fig. le, not shown). A thin layer of oxide (16) is grown in the windows and overall covering (18) of silicon nitride formed followed by an overall covering (20) of polycrystalline silicon. The top of the silicon covering is oxidized and the oxide selectively removed then the silicon to leave the polycrystalline silicon gates 20<SP>1</SP> and 20<SP>11</SP> (Fig. 1g).

Title: Process for the manufacture of porous shaped bodies that contain ion exchange synthetic resins
IPC: B01J47/00
Filed: 1963-07-23
Abstract: A porous shaped body containing an ionexchange synthetic resin is made by sintering a mixture of carbon, the ion-exchange synthetic resin and a thermoplastic synthetic material, which is present in an amount sufficient to form a cohesive skeletal structure after sintering, the heating being terminated before melting causes the thermoplastic synthetic material to adhere to the ion exchange synthetic resin.  The mixture may also contain a filler which can be removed by dissolving it out of the shaped body or which can remain therein.  In an example, the sintered mixture consists of equal proportions of polyethylene and a sulphonated styrene-divinylbenzene copolymer together with varying amounts of carbon.

[Also in Division H2] A connector 14, Fig. 9, connects two pairs of insulated telephone circuit wires, the operation being carried out in the crimping apparatus shown in Fig. 1. The connector similar to that of Specification 1,045,380, comprises two metal crimping ferrules 16, 18 formed with pressedout sections 30, 34 to give a preferred axis of bending A-A and tongues 26 pressed-out from the base 20 forming notches 28. The ferrules 16, 18 are insulated from each other by a film 40 of insulating material such as polyethylene terephthalate, bonded to the outside ferrule surfaces. The crimping apparatus comprises two block members 48, 481 slidably mounted on guide rods 52 and urged apart by springs 56, 56<SP>1</SP>. Both ends of a guide bar 74 of a connector support and wire cutter member 75 are spring-loaded in bores provided in the blocks 48, 48<SP>1</SP>. When the blocks are moved together the cutting blades 72, 72<SP>1</SP> recede into slots 70, 70<SP>1</SP> and the arms and slots 50, 50<SP>1</SP> interlace to bring a pair of die cavities 60, 60<SP>1</SP> into direct opposition. In operation, the support member 75 receives a connector, the arms 72, 72<SP>1</SP> locating in the slots 37 so that two ferrules 16, 18 face towards the die cavities 60, 60<SP>1</SP>. The pairs of wires approach from opposite faces of the member 75 and the individual wires are laid in the die cavities 60, 60<SP>1</SP> with their ends turned into the slots 70, 70<SP>1</SP>. When the two blocks 48, 48<SP>1</SP> are drawn together, by means of tool handles or a power driven tool head, the wires are sheared as cutter members 72, 72<SP>1</SP> enter the slots 70, 70<SP>1</SP> and the connector is engaged by die surfaces 60, 60<SP>1</SP> causing wall sections 22, 24 to curl over on to the wires. The wires impinge on the edge of notches 28 which pierce the wire insulation. In a further embodiment of the connector, the ends of the base portions of the insulating covering extend beyond the sidewall portion. These tongues may be gripped during the crimping operations to reduce the likelihood of bending along the axis of the connector.
