Title: Voltage-mode logic circuit
IPC: H03K19/0175
Filed: 1973-05-22
Abstract: 1410094 Logic circuits INTERNATIONAL BUSINESS MACHINES CORP 22 May 1973 [22 June 1972] 24318/73 Heading H3T In a voltage mode logic circuit comprising first and second monolithic circuit chips CH1, CH2 interconnected by a line L10 and each having a plurality of interconnected logic circuits LC1-LC5; LC6-LC9, the noise tolerance level and current gain are improved by having an output buffer circuit SC1 on the first chip CH1 with an output impedance lower than the output impedance of the logic circuits and an input buffer circuit RC1 on the second chip CH2 with an input impedance higher than the input impedance of the logic circuits thereon. The output buffer is preferably formed by an emitter follower T3 which also provides a high current gain at its output O2 while translating the signal voltage in a direction towards higher noise tolerance. The input buffer RC1 on the second chip is formed by a diode connected transistor T4. When the inter-chip signal is at a down level, diode T4 is forward-biased as to transmit the down signal to base of a transistor B2 which consequently is cut off and produces an output at the up level. When the inter-chip signal is at the up level, diode T4 is cut-off as to render B2 conducting to produce an output at the down level. Diode T4 isolates the logic circuit LC6 from noise on inter-chip line L10 while providing the required voltage translation. The logic circuits employed may be TTL (as shown) or DTL (Figs. 8A-9B, not shown). The input buffer may be formed by a complementary transistor (Figs. 6B, 9B, not shown). It is also stated that the logic circuits on the first chip are interconnected to form a latch. The Schottky diodes used in the TTL circuits prevent saturation.

Title: Storage to determine a connecting route via a switching network in telecommunication, particularly in telephone exchange systems
IPC: H04Q3/545
Filed: 1966-06-03
Abstract: 1,128,490. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 3 June, 1966 [4 June, 1965], No. 24790/66. Heading H4K. In an exchange system having a multi-stage, reed-relay switching network and a common control circuit, the latter includes a memory in which the busy/idle state of each link or switch is recorded on an individual core, and, associated with each core, is another core containing the address of the core on which is recorded the state of the first link (or switch) connectible to the link (or switch) whose state has just been ascertained. Fig. 2 represents a memory for a four-stage network having inter alia four A stage switches each with four inlets A11-A44 and three outlets A<SP>1</SP>11-A<SP>1</SP>43 and two D stage switches each having three inlets C<SP>1</SP>11-C<SP>1</SP>32 and two outlets, D<SP>1</SP>11-D<SP>1</SP>22. Assume the core of the BC link B<SP>1</SP>11 has just been interrogated and is found to denote a free state. Then in the associated core (actually a group of cores) of column AZ, the address 37 is found which corresponds to link C<SP>1</SP>11 which is the first CD link accessible to B<SP>1</SP>11. As shown, however, C<SP>1</SP>11 is busy (bit 1 in its core in the BZ column) so the control circuit interrogates the core at address 38. As this also is busy, the interrogation recommences with link B<SP>1</SP>12, whereby an address 39 of the next first accessible link C<SP>1</SP>21 is obtained. The process is then repeated. When a complete set of free links is thus determined the control circuit initiates the setting-up of the corresponding path through the network. Somewhat similar methods of route finding are to be found in related Specifications 1,126,075, 1,128,487, 1,128,488 and 1,128,489.

Filed: 1921-09-21
Abstract: 190,775. Chambon, L. Sept. 21, 1921. Machines for making boxes. Relates to the parts of a machine concerned in operating upon a strip of scored paper or other material, cemented for assemblage, to produce collapsed rectangular boxes of the form indicated in Fig. 3. The prepared strip b first passes under punches 1, Fig. 5, acting in conjunction with matrices 2 to cut the requisite notches and flaps in the blanks; the holder carrying the punches is given a reciprocating motion by eccentrics 4 and rods 5. The punching means can be regulated in position with reference to a knife 6 to which the strip next passes, in accordance with the particular length of box being made. The knife is caused to operate by a lever 7 during motion from a cam 8. After severance, the strip passes on to a thin plate 9 against which it is held by a hand- or pressure-operated device 10 having downturned edges 10, Fig. 4, designed to fold down the sides of the strip. Folders 11, operated by lever and link mechanism from a grooved cam 13, next come into operation to fold up the sides of the strip against the plate, and having done this they move clear of the plate, which is now caused to move forward to bring the folded box between rollers 18, 19, Fig. 1, which apply the pressure necessary to make the box sides adhere together, and then discharge it on to a plate 20. This plate 20 is caused to oscillate by lever and rod mechanism operated by a cam 25, and delivers the boxes into a receiving compartment 26, wherein they are retained by hooks which are moved aside to permit the passage of the boxes by lever and link mechanism operated from a cam, and return to place as the plate 20 regains its normal position.
