Abstract: 916,587. Liquid fuel burners. RENNER, J. Aug. 19, 1960 [Sept. 7, 1959; Nov. 27, 1959; March 5, 1960], No. 28806/60. Class 75 (1). . A liquid fuel atomizing nozzle head 10 includes a piston valve 20 which is opened by fuel pressure and which, on closing, withdraws fuel from the atomizer 5. The valve is threaded into the atomizer 5 and is disposed in a chamber 11 in the head 10 supplied with fuel by a pipe 4. The valve comprises a piston 21 and a cylindrical portion 22 connected together by a conical portion 25 which seats, in the closed position of the valve, on a conical annular flange in the interior of the valve housing 17. When the valve is opened by fuel pressure in the chamber 11 acting on the piston 20, radial bores 28 in the housing 17 are uncovered and the fuel flows therethrough and then through bores 29 in the conical portion 25 to the interior of the housing 17 and so to the atomizer 5. The fully open position of the valve is determined by a screw 23 on the end of the piston 21 abutting a shoulder 33 in the housing. The valve is returned to closed position by a spring , 24. A cylindrical oil filter surrounds the radial bores 28 in the housing. In a modification, Figs. 6, 7 (not shown), the radial bores 28 terminate at their inner ends on the surface of the conical flange on the inside of the housing 17. In a further embodiment, Figs. 8, 9 (not shown), the movable valve member is cylindrical and slides on the outside of a cylindrical housing connected to the atomizer. Apertures in the movable member and the housing register in the open position of the valve to form a passage for the fuel to enter the housing. A filter surrounds the movable member.

Title: Switching matrix control
IPC: G06F13/22
Filed: 1972-06-21
Abstract: 1367849 Data processing BURROUGHS CORP 21 June 1972 29127/72 Heading G4A Requests from units CN0-CN7 (Fig. 1) for access via a switching matrix 10 to terminal units EU0-EU19 are stored in the order in which they arrive in a memory 20 and processed on a first come-first served basis. Initially eight control status units 12, 14... 16, each associated with a requesting unit CN0-CN7 are in their idle state. When one is signalled by its associated requesting unit it signals a scanner 18 to insert the address of the requesting unit at the bottom of the memory 20, the memory positions then being adjusted. This is repeated until the addresses of all requesting units are stored and the scanner 18 energizes an address counter to read out the contents of the memory starting at the top so that the first stored address is read to a control interface unit 22. This address is decoded to enable (1) a set of gates (104, 106, Fig. 4, not shown) in interface 22 associated with the selected requesting unit so that the address of the desired terminal unit is transmitted on leads EU to the status control units 12, 14...16 and EU status unit 24, and (2) to enable a gate (38, Fig. 2, not shown) in the associated status control unit. The status unit 24 determines whether the desired terminal unit is busy and if it is not the gate (38) is enabled to pass the terminal address to a store (42). The terminal address is then decoded to feed a signal to the appropriate connection in the switching matrix 10 so that the requesting unit is linked to the desired terminal unit. If the desired unit is busy the memory scan is continued, the address of the unserved requesting unit being held in store. The memory comprises eight registers each having a flag bit, set to " 1 " when an address is entered and reset to "0" when the requesting unit corresponding to the address is serviced. In the event of two of the requesting units simultaneously applying request signals a priority circuit in the scanner 18 determines the order in which they are stored by activating only one output associated with the highest priority unit (according to a predetermined priority). A coder converts the priority output signal into a binary coded address for entry into the memory 20.

Title: Improvements in or relating to Communication Networks
IPC: H04Q11/04
Filed: 1967-06-26
Abstract: 1,182,487. Automatic exchange systems; multiplex transmission; multiplex pulse code signalling. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 26 June, 1967 [27 June, 1966], No. 29327/67. Headings H4K, H4L and H4R. In a telephone system the switching equipment has a broad band characteristic so as to be capable of passing broad band intelligence such as television as well as normal calls, and each call (or other transmission) is accompanied by signals specifying the type of modulation and band width of that transmission. P.C.M. and F.D.M. inter-exchange links can thus be interconnected to provide say an alternative inter-exchange route if a more direct route is busy. A group of trunks e.g. taken from an earlier switching stage may be used for a single call to provide an increased band width. The equipment shown is located at an intermediate exchange through which a call between subscribers in two other exchanges is to be routed. Signals arriving at the terminal 3 from the exchange of the calling subscriber specify the type of modulation, the channel on which a call will arrive, the band width necessary for the transmission and the numbers of the subscribers involved. Assuming the modulation is P.C.M., a register translator RTL and a marker MK enable a branching pulse generator to generate pulses coincident with the time slot or slots allotted to the call. Multiplex P.C.M. signals enter at terminal 1 and after a delay at D leave at terminal 2 via an inhibit gate. The circuit is synchronized with these signals by a framing circuit FRM and a timing pulse generator T1M. The pulses from the branching pulse generator B1PG enable the inhibit gate and an AND gate, causing the P.C.M. signals in that time slot to be deleted from the multiplex train and divided out through the " AND " gate. The individual pulses of the divided out pulse code are separated on to different lines and lengthened to fill all the time slots. Switching to a required output trunk can then take place through the switching network SWN purely on a space division basis and recoded and multiplex on an outgoing line. F.D.M. signals entering at 4 are separated on to individual channels at E and applied to the switching network where they are switched on a space division basis.
