Abstract: 600,384. Superheterodyne receivers. WYKES, J.P. Oct. 13, 1945, No. 26810. [Classes 40 (v) and 40(vi)] In a superheterodyne receiver, station selection is carried out by switching into the local oscillator circuit one of a number of piezoelectric crystals, such crystals forming the sole frequency determining element of the local oscillator circuit. The frequency changer 2 has input signals applied to its second control grid G4 through a coupling circuit 3 which is either aperiodic or has a pass-band equal to the wave-band covered by the receiver. Grids G1, G2 are coupled regeneratively by capacitor 4 and any one of a number of crystals X1-4 selected by push-buttons P.B1-4. Each crystal is cut for a local frequency which beats with a particular input frequency to produce the intermediate frequency in the tuned anode circuit. The output from terminals O may be fed to a 'second frequency changer having a local oscillator of fixed frequency.

Abstract: 761,198. Pneumatic conveyers. SIMON HANDLING ENGINEERS, Ltd. Sept. 2, 1955 [Sept. 17, 1954], No. 26973/54. Class 78 (1). A mobile unit for handling granular material pneumatic granular material receiving and comprises a power-driven vehicle fitted with delivering means, means for driving said pneumatic means from the engine, and means for carrying pipe sections for connecting said pneumatic means to the points where the material is to be drawn in and delivered. An exhauster 5, driven by a shaft 4 from the gearbox of the vehicle, is connected by a receiver 6 and a pipe 7 to a grain receiver 8 in which there is a cyclone separator 9. The receiver has an inlet 10 to which the end pipe of a series 28 is connected. These pipes are stored in racks 27 when not in use. Grain is discharged from the receiver through a rotary valve 11 and is directed by a two-way valve 13 either to a worm conveyer 14 feeding an elevator 15 or to a pipe 16 leading to a discharge pipe 17. The elevator discharges by a shoot into a receiver e.g. a vehicle, and the pipe 17 can be extended by connecting pipes 28 thereto. The air discharged by the exhauster 5 passes through a pipe 25 to the pipe 17. When the pipe 17 is not in use, the air from the exhauster is discharged to atmosphere through a silencer 24.

IPC: H04L27/18
Filed: 1974-06-06
Abstract: 1473084 Data transmission; coding for PSK systems POST OFFICE 6 June 1974 [6 June 1973] 26981/73 Heading H4P A coder for a P.S.K. triple input system, has means for clocking and providing complemented data which on binary addition provides a modulo-8 sum to triple outputs. In the embodiment described the binary adder converts Gray code to normal binary, adds, and then converts back to Gray code, which controls an 8 phase system. Data stream inputs A-C are fed to OR/NOR gates G1-G3 providing complemented outputs. Logical operation A# + #B is performed by gates G5-G7 which perform an exclusive OR function and provides outputs E, # on which a similar operation is performed in gates G8- G9 with stream C to provide from G10 outputs F, F thus input Gray has been converted to normal binary, the stream A being identical in both cases. Modulo-8 summation begins with least significant digit F in G18-G20 with delayed and fed back output through flip-flop FF1, the gates also providing a carry function when required. Output at G18 is next added to E in G15-G17 with a carry digit being provided through G14 when both E and output of G18 are 1. Output of G17 is then added to the stored previous output through flip-flop FF2 in gates G21, G23 and carry digit from G14 is added to the most significant digit in G11-G13 output from which is added to the previous delayed output through flip-flop FF3 in gates G24- G26, further carry operations not being required as number of digits = 3. As the most significant digit in both Gray and normal binary is identical this may be extracted from terminal 5. Output of G23 is next significant digit in normal binary and appears on terminal 8 but is converted to Gray in exclusive OR G27-G29 and the least significant digit in normal binary appears on terminal 9 or through Gray code converter G30-G32 on terminal 7. OR/NOR elements may be replaced by AND/ NAND gates with inputs connected together and the arrangement may be fabricated as a single structure using bipolar transistors of field effect (MOS) arrangements. Flip-flops FF1-FF3 are of the clocked type i.e. input is transferred to output at each clock pulse applied to clocking terminals.

Title: Data transmission systems
IPC: G06F13/40
Filed: 1971-04-19
Abstract: 1313623 Digital transmission; master and slave systems INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [21 April 1970] 26989/71 Heading H4P Each of a plurality of transmission units (4-6, Fig. 1, not shown) is selectively connected to at least one of a unit directly, or indirectly through at least one further unit, in dependence on a tag portion of a message containing a destination address. Each unit has a routing table assigning a route to the message in accordance with the address, a substitution address being used when no direct path is available. The routing table includes an entry for each path which can be used and an indication of the availablility of each path. Each unit may transmit test messages periodically which if correctly received, a return message updates the availability indications in the routing tables of all units through which it is transmitted. Such test messages are only transmitted along paths specified by the routing tables.  An intermediary unit receiving a message in transit which cannot be forwarded returns the message to the originating unit which updates the availability indications in the corresponding routing tables. The routing programme is determined by a table 50, Fig. 3, having a plurality of entries corresponding to the destination address. Table 50 has two entries, e.g. 53, 54 for each destination address, e.g. 7, the first entry 53 specifying a sub-table 51 designating the preferred channel or channels while the second entry provides a substitution address. Thus if controller 5, Fig. 6, is to route a message to a destination 2 which is found to be directly inaccessible then substitution address 9 is used causing sub-table 3, 9, 11 to be examined and if this is inaccessible substitution address 10 is used. A portion of sub-tables, Fig. 3a, is used to record the availability of lines, X indicating whether a line is locally unavailable and Y if remotely unavailable. Lines marked available which become unavailable when actual messages are sent have these messages returned to the transmitting unit and X, Y is altered accordingly. Re-routing of messages is not carried out by intermediate stations but only by the originating unit. Units need not be connectable to every other unit but may be connectable to selected units.

Title: Improvements in or relating to methods of producing metallic fabrics

Filed: 1931-09-29
Abstract: 376,559. Metallic fabrics. RILEY, F. B., 2, Bradford Road, Newton Highlands, Massachusetts, U.S.A. Sept. 29, 1931, No. 27166. [Class 45.] A metallic fabric is formed of a laver of parallel strands 1 .. 6, Fig. 1, and another layer of transverse parallel strands 7 .. 14. The strands 1, 3, 5, &c. of one layer are bonded by spot-welding to the strands 7, 9, 11, &c. of the other layer at their crossing points 16 and the other strands 2, 4, &c. of the first layer are similarly bonded to the other strands 8, 10, &c. of the other layer at their crossing points 15. Two inseparable but relatively movable fabrics are thereby produced so that a large number of different patterns may be formed from the one initial fabric by moving one component fabric relatively to the other to alter the spacing or angle or both spacing and angle of the strands of one component relatively to those of the other. That shown in Fig. 3, for example, is produced from the fabric shown in Fig. 1 by the displacement of one component fabric vertically and laterally relatively to the other component fabric, and that shown in Fig. 6 has been produced by the relative angular movement of the two component fabrics of a fabric similar to that shown in Fig. 1 but having diamond-shaped meshes. In the form shown in Fig. 9 every third strand of one layer is bonded to every third strand of the other layer and two of the component fabrics thus produced have been moved away from one another and towards the third component fabric having the strands 19, 20, 21, 24, 25, 26 to produce the pattern shown.
