Title: Fire extinguisher
IPC: A62C13/76
Filed: 1988-06-07
Abstract: The handle (6) is locked in the inactive position by a spring-tensioned (19) plunger (9) carrying a striking pin (15). When the handle (6) is grasped after removing the locking pin (9), the weight of the container (1) causes the handle (6) to pivot in the working position. As it pivots, an operating member (13) on this handle acts on the plunger (14) and causes the cartridge (17) containing the compressed inert gas to be opened, which then expands into the container (1). As the handle (6) reaches the end of its stroke, the operating member (13) ceases to act on the plunger (14), which returns to its initial position under the action of its spring (19). The handle (6) is then immobilised by this plunger. To release it, it is a simple matter, after removing the cover, to extract the cartridge (17) and engage a spanner (30) with a thread (20) on the plunger (14) and pull to free the handle which is then able to return to the inactive position. <IMAGE>

Filed: 1989-07-20
Abstract: A time-dependent engine output power characteristic curve 
for an engine output power to vary therealong to a target value 
which corresponds to an indication of intention of the driver for 
acceleration or deceleration (e.g., the amount of depression of 
the accelerator pedal) is established based on the difference (ΔPs) 
between a target engine output power (Psr) and an actual engine output (Pso) 
power. Then, a target rate of change of the rotational speed of 
the engine and a target rate of change of an indication of an 
engine load are established so that the actual engine output 
power varies along the engine output power characteristic curve, 
and the throttle valve and the continuously variable transmission 
of the engine are controlled using the target rates thus 
established.

IPC: G06F19/00
Filed: 1990-06-01
Abstract: An interfacing device for connecting the processing unit 
of a computer games system to an external data storage 
medium has a user-operable selection unit for generating a 
user-selected address and user-selected data. The 
user-operable selection unit may comprise user-operable 
switches or electronic latches that are set by a program 
in response to selections made by the user by means of a 
joystick, keypad or any other input device. An address 
comparison unit compares the user-selected address with 
the addresses from the processing unit, and a data 
switching device causes the user-selected data to be 
substituted for data in the storage medium whenever the 
compared addresses are the same. Instead of a 
user-operable selection unit, preselected addresses and 
preselected data may be stored in a ROM, which in one 
embodiment changes the way the computer interprets 
external memory and in another changes the computer's 
internal memory itself.

Title: Segmented induction skull melting crucible and method
IPC: H05B6/24
Filed: 1990-05-04
Abstract: The crucible (10) includes an upstanding sidewall 
formed of a plurality of internally cooled, metal 
segments (12) arranged in side-by side relation to form a 
crucible chamber (15) for receiving the metal to be melted. 
The segments (12) are separated from one another by 
longitudinal gaps (G) that communicate on the inside with 
the crucible chamber (15) and extend outwardly to the 
exterior of the sidewall. The gaps (G) are free of packing 
material that could constitute a potential source of 
melt contamination and are so sized in a width 
dimension where the gap and the chamber (15) communicate as 
to substantially prevent penetration of molten metal 
into the gaps (G) when the metal charge is initially melted 
in the crucible chamber (15) prior to the development of a 
solidified metal skull. Upper portions of the crucible 
segments (12) are restrained against outward spreading 
during use to provide a crucible (10) durable enough for use 
in production melting applications. The crucible 
eliminates the need for a CaF₂ type lining (skull) and 
for intersegment refractory packing material, thereby 
improving melt cleanliness.
