Title: Fuel injection pump for internal combustion engines.
Inventor: KRAEMER MANFRED
IPC: F02D1/12
Filed: 1992-07-28
Abstract: A fuel injection pump has an actuating mechanism for adjusting the pump delivery or timing e.g. by displacement of the control slide on the pump plunger (2), the mechanism comprising a double-acting piston displaceable in a cylinder (1) from an initial central position determined by springs (15, 55). To move the piston to one or other of its end positions, determined by stop surfaces (19, 39), a solenoid valve (6 or 46) is opened to admit pressure medium to the appropriate cylinder space (8 or 48). The other cylinder space is relieved of pressure via restrictions (9, 49) connected to a tank (50). A single spring may replace the two springs (15, 55). The mechanism allows an exact adjustment of injection without technically complex feedback sensors by virtue of the different, geometrically defined set positions of the actuating piston. <IMAGE>

Title: Fault tolerant processing
Inventor: FITZPATRICK ROGER SEAN
IPC: G06F11/16
Filed: 1992-09-21
Abstract: A dual lane computing system has at least one processor (2, 3) in each lane, each processor having an associated memory (18, 19) which stores input data supplied to the processor and the time of arrival. The lanes produce nominally-identical outputs which are supplied to a comparator (8) that detects when there is a discrepancy between the lanes. When a discrepancy is detected, an external processor (12) simulates the operation of the lanes. The data in the memory associated with one of the lane processors is supplied to the simulator processor in respect of the input just prior to the detection of the discrepancy. The simulator simulates the operation of one lane utilizing this data and its output is compared with the actual output of that lane as recorded when the discrepancy occurred to determine which of the two lanes is at fault. <IMAGE>

Title: Integrated barium-ferrite tuned filter-mixer
Inventor: TANBAKUCHI HASSAN
IPC: G01R23/173
Filed: 1994-11-25
Abstract: A routing barium-ferrite tuned resonator filter is integrated with an image-enhanced, single-balanced mixer. The barium-ferrite tuned resonator filter is preferably a four-sphere barium-ferrite tuned preselector 104 which is integrated with a harmonically mixed, image-enhanced, single-balanced mixer 105 to provide a high level of dynamic range in a harmonically mixed front end. An input resonator 110 of the preselector in combination with a dual PIN diode switch D1, D2 switches low-frequency input signals (e.g., 0 to 26.5 GHz) to a low-frequency output. For high-frequency input signals (e.g., 26.5 to 50 GHz), the four-sphere barium-ferrite tuned preselector is combined with the image-enhanced, single-balanced mixer which incorporates a GaAs monolithic diode bridge integrated circuit D4 - D7. This provides a front end component of a high-performance portable spectrum analyzer. Suspended stripline couplings 126, 142 couple R.F. signals respectively to and from input and output barium - ferrite spheres 124, 140. <IMAGE>

Title: Semiconductor laser device
Inventor: TAKIGUCHI TOHRU
IPC: H01S5/06
Filed: 1994-12-13
Abstract: A semiconductor laser device includes an active layer of a multiquantum well (MQW) structure comprising a plurality of well layers 12a, 12b, 12c and a plurality of barrier layers 13a, 13b, 13c disposed between the well layers. The barrier layer has a band gap energy that is largest in the centre of the MQW structure and gradually decreases toward both ends of the MQW structure, and the well layer has a band gap energy that is smallest in the centre of the MQW structure and gradually increases toward both ends of the MQW structure. Therefore, a semiconductor laser device that performs uniform injection of carriers and has a high emission efficiency and a broad modulation band width is realized. Similar results are obtained by using barrier layers and well layers which are thicker in the centre of the structure, and a barrier layer having a lattice constant which is largest in the centre of the structure. <IMAGE>

Patent GB-951332-A (GB)
Abstract: 951,332. Intercommunication systems. STANDARD TELEPHONES & CABLES Ltd. Feb. 6, 1961 [Feb. 10, 1960], No. 4378/61. Heading H4K. In a loud-speaking intercommunication system having a master station containing an amplifier and a switch contact for connecting a transducer to the output (loud-speaker operation) or input (microphone) of the amplifier and one or more substations, at least three lines are provided between the master and each substation, one of the lines being common to all, and contacts, controlled by a switch in the master station, effect connection of the other two lines to the output of the amplifier in one position of the switch and in the other position connection of only one line to the amplifier input so that in the first case a substation transducer when connected to either line will act as a loud-speaker and in the second case the transducer when connected to the one line will act as a microphone. Fig. 5 shows the master station 5 containing a transducer 7 which can be connected to the input or output of a transistorized amplifier 10 by contact al and also two substations 6, 6<SP>1</SP> containing transducers 8, 8<SP>1</SP> respectively. By actuating contact b1 (b1<SP>1</SP>) a substation can speak to the master station directly over line 2 (2<SP>1</SP>) and the common line 3 (3<SP>1</SP>) while the master may speak to a substation after operation of his contacts al, a2, a3 independently of the position of b1. The contacts d1 d2, d3 and d1<SP>1</SP>, d2<SP>1</SP>, d3<SP>1</SP>, &c., are provided so that the master can call and speak to any one (or more) stations to the exclusion of the remainder. A system which may be used as a " baby alarm " is shown in Fig. 4. Thus, if the switches controlling contacts a1, a2, a3 and b1 are retractive as would normally be the case in an intercom-system, the provision of a bi-stable contact c in the substation allows the master to continuously monitor the area in the vicinity of transducer 8, i.e. a child's nursery or a wharehouse, when contact c connects transducer 8 to line 2. The battery for the amplifier is normally disconnected but is switched-on when a substation calls by the operation of a contact b2 (actuated with b1) which " joins " line 1 to an additional line 4. In the " baby alarm " condition bi-stable contact e is operated by the master and for normal speech operation from the master station, contact a4 (actuated with a1, a2, a3) connects up battery.
