Title: Crankshaft
Inventor: ALMOR EMIL
IPC: F16C3/06
Filed: 1983-07-19
Abstract: A crankshaft has a completely hollow interior 18. This results in a substantial reduction in weight. In order to ensure that proper lubrication is maintained, openings 22 formed in the crankshaft walls forming the journals 10 and the crank webs 12 are connected by passages 24 which extend across the hollow interior and are made of a material other than that of the crankshaft itself.

Title: Impact testing machine
Inventor: ISHERWOOD DAVIS PAUL
IPC: G01N3/30
Filed: 1983-08-10
Abstract: An impact testing machine in which a specimen 14 held by a fixed mounting 15,16,17 is struck by a striker 1 carried by a pivotted arm 3. A motor (not shown), connected to the arm by a clutch 7, accelerates the arm at such a rate that the striker achieves useful speed within one revolution from stationary and the clutch operates to disengage motor and arm just before the striker hits the specimen so that the momentum of strike is independent of the motor. The necessary high angular acceleration may be imparted to the arm via a lost-motion connection using a reeled wire bearing upon a pulley 21. <IMAGE>

Title: A method of operating a fluidized bed reactor
Inventor: GARCIA-MALLOL JUAN ANTONIO
IPC: B01J8/24
Filed: 1986-06-10
Abstract: A method of operating a fluidized bed reactor in which a bed containing solid particulate material is fluidized by introducting air into the bed. A gas column is formed containing a mixture of the air, the gaseous products of combustion or gasification of the fuel in the bed and the particulate material entrained by the air and the gaseous products of combustion. The mixture is discharged from the vessel and the particulate material is separated from the mixture and returned to the bed. The entrainable particulate material is maintained in the bed and in the gas column in quantities sufficient to saturate the gas column. The temperature of the fluidized bed is controlled by varying the amount of air introducted into the bed. <IMAGE>

Patent GB-2202376-A (GB)
Title: Electrical appliances
Inventor: STANDLEY MICHAEL FRASER
IPC: A47J27/21
Filed: 1987-02-10
Abstract: An electrical appliance such as a cordless jug or kettle has a base 20 with an electrical mains connection and a working part 10 which can be separated from the base when in actual use. The working part includes a manually operated on/off switch 26-32 controlling an electrical load and suitable mating contacts 24, 25 are provided on the working part 10 and on the base 20 for connecting the power supply to the load via the switch when the working part is positioned on the base. To avoid the risk of the working part being removed from the base whilst current is flowing through the contacts, a weighted sensing member 40 is provided in the working part. When the working part is positioned on the base, the sensing member 40 is supported through contact with the base and remains stationary in an elevated position. As the working part 10 is lifted away from the base 20, the weighted sensing member 40 drops and, if the manual switch has been left in the "on" position - engages a switch member 26, 46 to move it to the "off" position before the electrical contacts become separated. <IMAGE>

Title: Seismic protection
Inventor: HERBERT RICHARD
IPC: G01V1/00
Filed: 1987-04-13
Abstract: To ensure that a nuclear reactor 11 or other damage-susceptible installation is, so far as possible, tripped and already shutdown before the arrival of an earthquake shock at its location, a ring of monitoring seismic sensors 14 is provided around it, each sensor being spaced from it by a distance (possibly several kilometres) such that (taking into account the seismic-shock propagation velocity through the intervening ground) a shock monitored by the sensor and then advancing to the installation site will arrive there later than a warning signal emitted by the sensor and received at the installation, by an interval sufficient to allow the installation to trip and shut down, or otherwise assume an optimum anti-seismic mode, in response to the warning signal. Extra sensors 14 located in boreholes may define effectively a three-dimensional (hemispherical) sensing boundary rather than a mere two-dimensional ring. <IMAGE>
