Title: Process of manufacturing valves for reciprocating piston  internal-combustion''ngines and valves so manufactured
IPC: F01L3/14
Filed: 1973-08-16
Abstract: 1439230 Making i.c. engine valves; welding by fusion MASCHINENFABRIK AUGSBURGNURNBERG AG 16 Aug 1973 [18 Aug 1972 17 May 1973] 38864/73 Headings B3A and B3R [Also in Division F2] A method of making a valve for an internal combustion engine, the valve having an evacuated inner cavity extending along its stem 101 and partially filled with a heat-conducting substance 111, which when the valve is in use is liquid, wherein two valve parts are provided of which a first part has an open-ended cavity, the heat-conducting substance is introduced in liquid form into the cavity of the first part, the valve parts are cooled to solidify the substance 111, the parts are assembled either before or after the cavity is evacuated and the parts are welded together in a vacuum chamber. The valve stem 101 is welded to the valve disc 107, preferably by electron beam welding, and during welding the stem is cooled to prevent melting of the heat-conducting substance. Cooling is effected by placing copper blocks on the stem and cooling coils may be used in addition. The inner cavity is partially filled with liquid sodium drawn off from below the surface of a supply in a reservoir, so that as far as possible contact with air is prevented. When the sodium has solidified, a closure member 110 is located on the valve stem, and when the parts are placed in the vacuum chamber, air is evacuated from the upper part of the bore 102 through recesses (not shown) formed in the member 110. The valve stem is formed with a central bore 103 communicating at one end with a collecting chamber 108, from which radiate recesses 109, and at the other end with the bore 102 via a constricted zone 105. Coolant flows from the bore 102 to the chamber 108 through a plurality of bores 104.

Abstract: 1466433 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 12 Sept 1974 [18 Sept 1973] 39790/74 Heading H4K Signalling or control information can be switched through a speech store of a TDM exchange either by using storage locations associated with free speech channels or, if all speech channels are in use, by utilizing the storage location of a busy speech channel. In the latter case the speech information which would have been switched is cancelled, the arrangement being subject to the constraint that only a predetermined amount of speech information associated with a particular channel may be cancelled. In normal operation speech samples are fed from a register 24 into locations of speech store 1 under the control of addresses which respectively appear in register 22 half a time slot earlier, and a connection store 2 controls the read out for the speech store locations. During the half time slots during which samples are being read into store 1, a central control can insert a binary 1 into any storage position of a further store 16 to indicate that it wishes to utilize the corresponding location of store 1 for transferring signalling or control data. When the particular storage location is due to be written into as indicated by the appearance of the location address in register 22, the binary 1 signal in store 16 is fed to register 19 to prevent any speech information in register 24 from being written into store 1 during the following half time slot. As a result the data from central control 11 is written into the store 1 for subsequent read out as determined by information fed into connection store 2 by the central control. The central data may relate to maintenance messages for testing the speech network, a message inserted into the speech store 1 being compared with the original message after it has been switched through the network.
