Title: Rotary regenerative heat exchanger
IPC: F28D19/04
Filed: 1971-12-18
Abstract: 1363769 Thermal regenerators R N PENNY 14 Dec 1972 [18 Dec 1971] 58898/71 Heading F4K [Also in Division F1] A thermal regenerator has a disc-type matrix 3 which is rotated by fluid impluse applied to impulse buckets formed at the matrix periphery. These may consist of bucket-like depressions 27 formed in the rim portion of the matrix, or they may comprise turbine blades. The impulse fluid is preferably tapped from one of the heat exchange fluids (e.g. high pressure air or turbine exhaust gases) and after use is returned to the appropriate fluid stream. The two fluids are separated in known manner upstream and downstream of the matrix by walls 4, 5, and these are hollow and carry bar-like seals 10, 11. High pressure air from passage 6 enters wall 4 via a port 23 and from there flows via a passage 19 behind the seal bar 10 to a passage 25 formed around the rotor between liner members 14, 15 and a location ring encircling the matrix. The ring is formed with nozzles 26 which direct the air into the buckets 27 and so effect rotation of the matrix. The spent air passes out of each bucket 27 via a port 28 which, when in registration with the seal 11, is said to permit this air to flow via the space 20 behind that seal to the wall 5 from which it rejoins the heated air stream 8 via a port 24. The location ring encircling the matrix is formed of interengaging blocks comprising metal blocks 16 and ceramic blocks 17, and is positioned in the chamber defined by the liner members 14, 15, being located therein by means of coupling members 18 which permit limited radial and circumferential movement of the blocks relative to the liners.

Abstract: 1373414 Automatic exchange systems WESTERN ELECTRIC CO Inc 21 Dec 1971 [24 Dec 1970] 59324/71 Heading H4K [Also in Division G4]  In a parallel cellular logic system there is at least one logic cell comprising a number of bistable devices 33, 36-38 to which data signals are applied in multiple from a selected one of a number of sources IN, 42, 39, each device having a selectively enabled input, circuits providing different control signals ACON, BCON, SCON corresponding to the bi-stables, and a circuit 61, 62 preventing application of data signals to the bistables upon coincidence of a control signal with a given state of its corresponding bistable. There are preferably a number of cells connected over bus 17, 18, each cell including a store 42 (e.g. semiconductor) for holding the corresponding bit from each of a number of words.  Operation.-An external register selects a number of cells over leads 55 and certain control bi-stables in the selected cells are set by instructions such as IN, I, A which applies a I to wire 46 via gate 61 and sets bi-stable 33. A sequence of such instructions supplied by a read-only memory sets up initial conditions. The initialization instruction sequence is skipped by branching in all subsequent program cycles. A control input POL and exclusive OR gate 52 can be used to complement the data bit from the source selected by gates 56-58. The contents of an addressed bit location in store 42 or of data bi-stable 39 can also be inserted in an addressed location of store 42 or in bi-stable 39 with or without complementing via gates 57, 58, 61, 62 and bus 43. The application of a right or left control signal to gate 49, 50 enables the data carried by bus 43 of a cell to be propagated to successive cells on either side until a cell with a set STOP bi-stable 37 is reached. In such propagation the data is entered into the data bi-stables 39 via gate 72, 73. Bits of two locations in store 42, or any two of the sources, may be matched by using the first bit to set or reset bi-stable 39, applying the second bit to bi-stable 39 and indicating a mismatch if there is a change of state. The system may be used as a scanner in an electronic communication system central office. The first two storage locations are used to store the most recent and the previous state of a line associated with the respective cell. These states are respectively transferred to the B, A bistables, the A bi-stables of cells in which a change of state is detected are set, all others being reset, the left-most A-active cell is marked by maintaining its D-bi-stable reset while setting the D-bi-stables of A-active-cells to the right, the A bi-stables in these cells are reset, the control processo is notified by a signal on wire 28 (POL, I, OUT (sink)), and by a sequence of instructions ACON, S(source), I for the remaining store addresses, the identity-of the line is transmitted from store 42 to the control processor. The contents of the second store location are then updated from the first location for that cell.

Abstract: 1279910 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 17 Dec 1970 [31 Dec 1969] 59926/70 Heading H4K In a register connector a selector circuit, common to a group of switches CS1 to CS6, selects one of such switches concurrently demanding the service of common markerconnector apparatus, by means of a chain circuit of transistors T1 to T6 the emitters of which are connected to the junction points P1 to P6 of a loop of diodes D1 to D6, a switch S selectively earthing any one of the junction points to vary from time to time the point of first preference in the chain. The switch S may be mechanical or comprise an electronic counter. If earth fails to be provided over the contacts of the switch S, potential from a Zener diode Z21 and diodes D31 to D36, individual to each junction point, allows the selector circuit to function but without order of preference. Demand conditions from the switches appears as closure of contacts ea (LAC) in the vertical wires CW1 to CW6 of a diode matrix and results in the charging of capacitors C11 to C16 in the base circuits -of transistors T1 to T6. As the diodes D11 to D16 provide an increasing bias, diode by diode, round the loop from the junction earthed by switch S, that transistor at the earthed junction, or that transistor closest to the earth in the forward direction, conducts first. With a transistor, such as T1, conducting, all other transistors are locked out as the collector circuit connects earth over diode D21 to the vertical wires CW2 to CW6 of all other transistors. One of the relays L1 to L6 corresponding to the operated transistor is energized and contacts, such as l11 and l12 of relay L1, provide a direct lock out earth to the vertical wires CW2 to CW6 and an interference proof base bias to the operated transistor over diode D61 and Zener diode Z11. The verticals CW1 to CW6 of the matrix may be clamped to earth over diode D7 and diodes D81 to D86 so that by operation of contacts am the demands manifested by operated contacts ea (LAC) may be connected to the transistors T1 to T6 at one and the same time.
