Title: Message transmission system
IPC: H04J3/24
Filed: 1974-08-06
Abstract: 1473523 Multiplex transmission INTERNATIONAL BUSINESS MACHINES CORP 6 Aug 1974 [28 Sept 1973] 34477/74 Heading H4M In a message transmission system comprising a transmitter A, Fig. 1, including message sources E 1 -E n  connected to a transmission register MA, messages comprising only message information and not address information as such, are transmitted from the transmission register MA and at least part of the content of the transmission register is used to select the next message source E 1 -E n  from which the content of the transmission register is to be derived. In Fig. 2A the transmitter A includes shift registers 101, 102 forming the message sources E and a memory 130 for the transmission register MA and a data output from a latch 152 is fed via 311 to a modulator (301, Fig. 2c, not shown) and over a line (302) CC to a demodulator (303). At the receiver B, Fig. 1, the output (321) from the demodulator (303) is fed via a latch (252, Fig. 2B, not shown) and AND gates (221, 253) which form a distributer DB to registers R (201, 202). Decoders CA and CB such as 140 including an AND gate 142 and an inverter at the transmitter and (240) at the receiver cause the registers 101 and R1 (201) to respond to configurations "00", "10", "01" of the contents in memories 130 and MB (230) and registers 102 and R2 (202) to respond to "11" of the contents in memories 130 and MB (230). At the transmitter clock signals at 312 from the modulator (301) are fed via delay circuit 15 to AND gates 111, 112 and depending on the binary information signal stored in the memory 130 the output from the decoder 140, CA selects the next message source register 101 or 102 by means of distributer DA formed by AND gates 121, 122. The receiver memory MB (230) and decoder CB (240) function in a similar manner in response to clock pulses at (322) from the demodulator (303) except that additional delay circuits (251) and (250) are provided such that control of the memory MB (230) determines the destination register R 1  or R 2  (201 or 202) to which the next received information unit of data is transferred from the memory MB (230). In a further embodiment (Fig. 4, not shown) the information units in the last two stages of a shift register (SR 1 ) at the transmitter and a shift register (SR 2 ) at the receiver are used in a similar manner to above to determine, by decoders (D 1 , D 2 ) controlling gates (A 1 , A 2 ) at the transmitter and gates (A 3 , A 4 ) at the receiver, the next buffer register (T 1  or T 2 ) at the transmitter to be connected to the shift register (SR 1 ) and the next buffer register (T 3  or T 4 ) at a central processing unit (UC) of a computer to be connected to the shift register SR 2 . The buffer registers (T 1  and T 2 ) transmit at rates of 3600 and 1200 bands respectively.

Abstract: 847,240. Bearings. MURPHY, A. J. Feb. 6, 1958 [Nov. 13, 1956], No. 34717/56. Class 12 (1). The bearing surfaces 2, 3 of a downwardly loaded vertical shaft 1 and a bare component 4 respectively, are separated by a disc 5 meshing with a pinion 8 which is driven at a speed high enough to establish full hydrodynamic lubrication and eliminate boundary lubrication with its consequent high friction. The power for rotating the disc 5 may be derived either from an independent source, e.g. an electric motor, or from the main drive of the machine through gearing. In the case of two flat surfaces in slow relative movement the disc may have its centre located outside the area of the two separated surfaces. In a thrust bearing having annular bearing surfaces an intermediate concentric annulus may be used, an intermediate bush, driven from one end, being employed in the case of a journal bearing. Two intermediate members driven at the same speed in opposite directions may also be incorporated.

Title: Heat exchangers
IPC: F28D7/16
Filed: 1972-07-26
Abstract: 1396799 Supporting heat exchange tubes BABCOCK & WILCOX CO 26 July 1972 [27 Aug 1971] 34958/72 Headings F4A and F4S In a heat exchanger in which tubes 27 for a heating fluid extend within a flow of fluid to be heated, apertured plates 44 are provided to support the tubes; each aperture, e.g. 46-49 and 86, having at least three inwardly projecting portions separated by gaps, the innermost edges of which portions terminate in arcs which define a circle slightly greater than a tube to be received. This construction allows for inaccuracies in tube alignment while discouraging crevice corrosion. The apertures shown in Fig. 2 are formed by drilling holes in the plate and forming gaps in the circumference of each hole by a broaching operation to define the projecting portions, the size of the gaps being formed in accordance with the desired flow rate of heating fluid across the plate (Fig. 3, not shown). An alternative method of forming an aperture is to drill a central hole then apply a multiple spindle drill to the hole to form the gaps, Fig. 5; although less expensive this technique does not produce as much flow area as the corresponding broached aperture. A non-uniform separation of the support plates is established by having a support rod (81, Fig. 4, not shown) secured to one of the tube sheets 14, 23 each rod carrying spacer tubes interspersed between the plates. Heating fluid, i.e. nuclear reactor coolant enters at 15 and leaves at 20; feedwater is supplied via nozzles 35, 36 from a header 34 and flows on the outside of shroud 26 to ports 30 before rising over the tubes 27 to emerge as superheated steam from ports 40. An auxiliary feedwater header 41 communicates with the upper region of the tubes 27.
