Title: Improvements relating to fuel injection in internal combustion engines
IPC: F02M61/00
Filed: 1940-07-25
Abstract: 542,844. Fuel injection pumps. KAMMER, G. S. July 25, 1940, No. 12167. [Glass 102 (i)] [Also in Group XXVII] In fuel injectors comprising a nozzle with two or more orifices controlled by separate needle valves, fuel is supplied to the needle valves from separate outlets in the pressure space of the fuel pump, one outlet being controlled by the pump plunger, and at least one other outlet being in continuous communication with the pressure space. Fig. 1 shows a pump 1 with piston 2 controlling an inlet 3 for fuel, and on outlet 5 connected to a passage 27, Fig. 4, leading to one 23 of the needle valves. A second outlet 4 is always open to the pressure space of the pump and lead to a passage 26 for the other needle valve 22. The inlet 3 and outlet 5 are controlled respectively by helical edges 6 and 7, Fig. 3, of a groove in the piston 2, the timing being varied by rotation of the piston. Fuel is first injected at a high pressure through the outlet 4 and past valve 22, and afterwards at a lower pressure through the outlet 5 and past valve 23. The spring 24 closing the valve 22 may be stronger than that 25 closing the valve 23, so that when both are being supplied with fuel pressure, the valve 22 will close. The first injection begins preferably about 2 degrees to 7 degrees before inner deadcentre, and the second either at or just after the dead-centre. The valve 22 supplies orifices 36 through passages 34, 35 and the valve 23 supplies orifices 33 through passages 29, 30, 31. The upper face of the pump piston 2 may be wholly or partly helical ; also the outlet 5 may be lower than the inlet 3, the groove in the piston 2 then having only one helical part. The piston 2 may be driven by an eccentric so that only the middle part of the stroke is used for feeding fuel. Specifications 534,724 and 535,151, [both in Group XXVII], are referred to.

An associative memory system includes bistable indicators, which may be cryotrons set according to matches and mismatches between stored words and interrogating words, and a control circuit selectively operable to set all the indicators to one or other of the two states so that either the matches or the mismatches switch the corresponding indicators to the other state. As shown a store 2 holds words entered into vacant registers under the control of a vacant register indicator 2. Individual to each register is a compare circuit which enables one of three corresponding outputs such as 33, 36, 37 accordingly as selected bits in that register are greater than, equal to, or less than the corresponding unmasked bits of an interrogating word in an interrogation register 6. Each of these sets of three outputs pass through a corresponding cryotron gate network having two outputs each such as 35, 39. Three common control lines 15, 17, 19 connect all the networks and according to which one of these three lines is enabled the outputs 33, 36, 37 are split into " greater than or equal to" and " less than" " equal to" and " other than equal to", or " less than or equal to" and "greater than" respectively and passed to conductors 35, 39. Each match indicator consists of a bi-stable pair of cryotrons such as 41, 45. Common reset lines 97, 103 are provided so that every pair may be set in one or other of the two states, and one of one of a pair of control lines 79, 81 is energized to gate either the "accept" or "reject" lines such as 35, 39 so that they may switch the corresponding pair to the other state. The apparatus shown is particularly suitable for determining which words in the store are in a particular range and a buffer 26 is provided to hold the upper limit while the lower limit is in the interrogation register 6.

Abstract: 1464002 Automatic exchange systems CSELT CENTRO STUDI E LABORATORI TELECOMUNICAZIONI SpA 21 March 1974 [21 March 1973] 12558/74 Heading H4K In a PCM, TDM speech and data transmission system a speech connection may be established between two stations interconnected for data transmission during an interruption in data transmission by using a first part of the existing data transmission path and by by-passing a second part, the second part of the path being held in a set up condition during the speech connection. Depression of a calling button connects a data set M with a synchronization unit ED via a four wire path 1, a space division concentrator CS, a supervisory junctor CDD, a modem MC, a bit grouping device 1E, a PCM multiplexer TPCM and a time channel of a highway AD of a TDM switching network RCF-D. Unit ED receives the address of the called terminal and with the aid of a SPC central processor EL causes a path to be set up to the called terminal using a time channel of highway CB. The unit ED also ascertains the data transmission rate of the calling terminal and causes the modems MC connected to the calling and called terminals to be set up for the required data transmission rate. During a data connection the unit ED provides for the necessary time slot interchange between highways AD and CB. To switch over to speech transmission a button is depressed at the calling or called terminal to cause central processor EL to connect the junctors CDD directly to the multiplexer TPCM via paths m and to cause a channel of a highway AB to be allocated to the connection, thereby by-passing the unit ED. Switch contact 1 at each station DF is operated and the telephone sets are connected to two wire paths f of the four wire connection g. On termination of the speech connection, the data connection is automatically re-connected. The network RCF-D is said to be of any standard form, the system also provides for voice only or data only connections.
