Title: Pneumatic vacuum power booster for vehicle clutch or brake hydraulic systems
Inventor: WAGNER WILFRIED
IPC: B60T13/52
Filed: 1988-01-13
Abstract: A pneumatic vacuum power booster (2) has in its booster housing a vacuum chamber (23) of constant pressure, a working chamber (24) of variable pressure and a movable wall (22) cooperating with a working piston (4), a control valve device which is controllable by a control piston (3) and is formed by a first (29) and a second (28) valve seat as well as a poppet valve (30) coacting with the two valve seats. Movement of the movable wall (22), caused by a pressure difference which acts thereon, is transmitted onto the working piston (4). Movements of the working piston and of the control piston take place in opposite directions upon actuation of the vacuum power booster. The booster housing (21) incorporates a chamber (7) which is in permanent communication with the atmosphere and which is connectible with the working chamber (24). The poppet valve (30) in its inactive position abuts with its sealing surtace on the second valve seat (28) on the control piston (3) and is biassed in the actuating direction of control piston (3). The working piston (4) is rigidly coupled to the movable wall (22), with the control valve housing (6) being arranged within the booster housing (21). <IMAGE>

Title: Digital fuel control system for I.C. engines
Inventor: OSTDIEK ARTHUR JOSEPH
IPC: F02D41/18
Filed: 1991-01-15
Abstract: A digital fuel control system for a small internal combustion engine has a pressure sensor for detecting the instantaneous pressure in the air intake manifold of the engine to generate air pressure data. A microprocessor responsive to the air pressure data generates a fuel quantity output signal indicative of the quantity of fuel to be delivered to the engine. A fuel metering apparatus responsive to the fuel quantity output signal generated by the microprocessor meters the fuel being delivered to a fuel delivery mechanism which delivers the fuel into the air intake manifold of the engine. The microprocessor in response to the instantaneous and cyclicly varying air pressure data generated by the pressure sensor determines the engine's speed and the average pressure of the air inhaled by the engine. The engine speed data and air pressure data address a look-up table to extract data indicative of the fuel requirements of the engine. <IMAGE>

Title: Passenger conveyor control apparatus
Inventor: SAKATA KAZUHIRO
IPC: B66B25/00
Filed: 1991-02-20
Abstract: An escalator or moving walkway control apparatus includes two or more microcomputers (81, 82) which monitor safety devices and execute a stop operation if any are activated. They also monitor each other and suppress the stop operation if it is generated in error through computer failure. The first microcomputer (81) executes sequence processing concerned with running of the escalator. The second microcomputer (82) executes processing in which the actuation of any safety device is detected, the operating situations of the safety devices of the escalator are judged, and the judged results are communicated via a telephone interface (105) and a public circuit (107) to a centralized monitoring office (109) for maintenance. A warning alarm is sounded prior to an emergency stop and new passengers can be prevented from getting on the escalator. <IMAGE>

Title: Apparatus to measure the profile of a surface
Inventor: BAILEY RICHARD JOHN
IPC: G01B7/28
Filed: 1991-03-12
Abstract: An apparatus 2 to measure the profile of a surface, for example the re-surfaced area of a hole in a road comprises parallel rails 4, 6 each of circular cross-section and mounted on a tripod arrangement 8, 10. A manually propelled carriage 12 has rollers running along the tops and undersides of the rails. The carriage carries a vertically movable surface follower comprising a rod 58 having a wheel 60 to run on the surface being measured. Variation in the surface profile causes the wheel and rod 58 to move up and down. This is observed by electro-optical sensor means. Further electro-optical means on the carriage produce a trigger signal each time it passes a marking 72 on the rail 6. The occurence of each trigger signal causes a record to be made of the height of the surface follower. <IMAGE>

Title: Encapsulating electrical components
Inventor: FORSTER JOACHIM
IPC: H01F7/06
Filed: 1991-03-19
Abstract: An encapsulated, explosion-proof electromagnet including a coil 16 and a core 18 is arranged in a housing 14 of plastics material or metal. The electromagnet is embedded in a first inner encapsulation 20 the free surface of which is covered by an outer encapsulation 22 formed of resiliently deformable material. The inner encapsulation material may be an epoxy resin and the resiliently deformable encapsulation material may be a silicone rubber. The outer encapsulation material may serve both to reduce the rate of loss of plasticiser from the inner encapsulation material and to maintain fluid and chemical resistance of the encapsulation. The outer encapsulation material may also serve as a cushion against differential thermal expansion of the housing and inner encapsulation. For stabilisation and better heat dissipation, the encapsulation materials advantageously contain mineral fillers such as, for example, stone dust or quartz. <IMAGE>

Patent GB-2263776-A (GB)
Title: Fluid mass flowmeter
Inventor: GIMSON CHRISTOPHER JOHN
IPC: G01F1/696
Filed: 1992-01-28
Abstract: A fluid mass flowmeter for providing an output representative of the mass flow of a target fluid through a conduit. A transducer is located in the conduit and heating power is supplied to the transducer. The rate at which power is supplied to the transducer, the temperature of the fluid within the conduit, and the temperature of the transducer are measured. A predetermined representation of the relationship between Reynolds Number and Nusselt Number is stored, the relationship being derived from test data obtained by passing at least one known fluid through the flowmeter at different flow velocities and at different power levels. A target fluid film temperature is calculated from the measured transducer and fluid temperatures, the film temperature being representative of the temperature of the target fluid adjacent to the transducer. Target fluid data representative of the variation with temperature of the target fluid viscosity and thermal conductivity is stored, and the target fluid viscosity and thermal conductivity are calculated from the stored target fluid data and the film temperature. The Nusselt Number for the target fluid is calculated from the measured rate of power supply, the difference between the measured transducer temperature and the measured fluid temperature, and the calculated thermal conductivity, and the Reynolds Number for the target fluid is calculated from the calculated Nusselt Number and the stored relationship. The mass flow is finally calculated from the calculated Reynolds Number and the calculated viscosity.
