Title: Interceptor units
Inventor: HILL-VENNING JOHN
IPC: B04C9/00
Filed: 1985-11-14
Abstract: An interceptor unit for receiving mixtures of petrol, oil and water and for discharging relatively clean water comprises a vessel (2) divided into an inlet chamber (4), an interceptor (6) and an outlet chamber (8). An inlet (12) enters the inlet chamber (4), and an outlet (36) discharges from the outlet chamber (8). Flow entering the inlet chamber (4) is transferred to the interceptor (6) through a conduit (18), where separation of the petrol and oil on the one hand and the water on the other hand takes place. From the lower region of the interceptor (6), relatively clean water is transferred to the outlet chamber (8) through an upwardly extending transfer passage (28), to be discharged through the outlet (36). Under conditions of heavy flow, the conduit (18) is unable to accept all of the mixture entering through the inlet (12), and some flow takes place from the lower region of the inlet chamber (4) to the outlet chamber (8) through an overflow arrangement (38). <IMAGE>

Title: Gear-shifting mechanism for preventing accidental engagement of reverse
Inventor: SCHMIDT VINZENZ
IPC: F16H61/24
Filed: 1986-09-12
Abstract: The gear shift mechanism according to this invention includes a selector shaft, rotatable by means of a shift lever for selecting various gear shift channels and axially displaceable for engaging the selected gear. The selector shaft carries a shift finger for engagement with the selector forks in the respective gear shift channels and a selector finger, which engages the slots of an internal shift gate to constrain the movement of the selector shaft. To prevent inadvertent engagement of the reverse gear, a pawl is rotatably mounted on the selector finger and is held by a spring biased detent in one of two stable angular positions, which are aligned with and perpendicular to the direction of the gear shift channels. A stop and at least one control pin are provided on the gate plate to cooperate with the pawl. The control pin changes the angular position of the pawl during gear selection movement of the selector finger relative to the gate plate and the stop prevents engagement of reverse gear when the pawl is aligned with the gear shift channels.

Patent GB-2193667-A (GB)
Title: Continuous casting installations
Inventor: KOHNO TETSUYA
IPC: B22D11/06
Filed: 1987-07-20
Abstract: A continuous casting installation comprises a rotary drum (1) with a channel formed in its periphery, a steel belt (2) which contracts a portion of the periphery of the drum to define a casting space and a discharge spout (3), the width of whose downstream end is less than that of the channel, arranged to discharge molten metal into the channel upstream of the casting space. In use, the flow rate is such that a proportion of the molten metal flows backwardly in the gaps between the edges of the channel and the main flow of the metal (7) to form back fed portions (15). The position of the leading ends (15a) of the back fed portions (15) is monitored by an optical sensor and the speed of rotation of the drum or molten metal supply rate is altered by a controller to maintain the position of the leading ends (15a) substantially at a reference position (16). This ensures paper filling of the casting space. The installation is especially suitable for casting zinc. <IMAGE>

Title: Fluid operated jack
Inventor: ALKER DEREK
IPC: F15B15/28
Filed: 1988-01-09
Abstract: A fluid operated jack comprises a piston rod 21 and a co-operating cylinder 24. Sensing means 54, connected to the piston rod externally of the cylinder is provided for sensing when the cylinder reaches a pre-determined position with respect to the piston rod, and actuating means 38, 46, 48 are provided within the cylinder for actuating the sensing means 54. The sensing means may be a balanced valve connected to an electrical signalling device 54 or a pilot valve. The actuating means includes a toggle lever 39 mounted on the piston rod for pivotable movement by a sleeve 40 when, at full extension, the sleeve strikes the cylinder end 27. Movement of the lever 39 displaces a rod 46 and a wedge 48 to operate the sensing means. The jack may for example be used to operate a hydraulic mine roof support, the piston being fixed with respect to the support and the cylinder being movable. The invention makes it possible to receive signals related to the position of the cylinder, with respect to the piston rod, without using hydraulic hoses or other connections which move with respect to the cylinder and would therefore be susceptable to damage.   <IMAGE>
