Abstract: A method for increasing the cross-flow microfiltration fluxes of waste waters containing suspended solids and/or emulsified oil through microporous thermoplastic tubes (32) by including therein a calcium compound selected from Ca(OH) 2  or CaSO 4 . The calcium compound is present in the waste waters in an amount ranging from above the solubility limit of the compound to about forty (40) percent by weight of the waste waters. The Ca(OH) 2  can be added directly to the waste water. The CaS0 4  can be included by reacting H 2 SO 4  and Ca(OH) 2  in the waste waters to form CaS0 4  in situ. Alternatively, wet CaS0 4  can be formed by reacting H 2 SO 4  with Ca(OH) 2  outside the water and then added to to the waste waters in the required amount.

Abstract: A multiple-character-impressing stamp of the individually-insertable-and-removable-character kind is hand-operated and is equipped with a mechanism which, when operated, will eject any selected one of the characters from the stamp without the need to dismantle the stamping head. The mechanism comprises a pushrod (28) which is slidable into and out of the character-holding head (11) of the stamp and which works in combination with a member (25) slidable or rotatable across the stamp body. The character-ejecting end of the pushrod (28) is constrained to move with said member (25) in linear or curving motion back and forth across the stamping head (11). A spring-loaded detent means (D, CS) locates and holds the movable member (25) in each of a plurality of selectable positions across the stamping head (11). When the member is so held, the end of the rod (28) is positioned behind a selected character-bearing block (15) and the rod can be operated to eject that character from the stamping head. A magazine is also disclosed which cooperates with the stamp in such a way that any selected character can be ejected from the magazine and into a character-receiving space in the stamping head without the need to handle the character-bearing blocks (15).

Abstract: A control system for a fluid activated clutch which includes a shut-off valve and a manually operable control lever connected to a control valve. A quantity of fluid retained in a fluid reservoir is pressurized by a pump and fluidly supplied to the clutch by fluid passages which interconnect the two valves. Movement of the control lever activates the control valve and allows pressurized fluid to control the position of the shut-off valve. After the fluid has been pressurized, the shut-off valve functions to prevent the clutch from being engaged by the pressurized fluid until the control lever has been depressed once and then released.

Abstract: A flat panel display device is described comprising a matrix of pixels arranged in rows and columns, and which does not require a large number of connections to addressing means external to the panel. The row and/or column conductors (14b, 15b, 16b, 17b, and 24b, 25b, 26b, 27b) are connected to voltage lines (18, 28) trough photoresistive device (14 to 17, 24 to 27) which are arranged to be sequentially illuminated by light sources (10 to 13, 20 to 23). The photosensitive devices may be photoresistors or preferably potential dividers comprising a photoresistor in series with a second resistor. This second resistor may itself be a photoresistor, which is illuminated immediately after the first photoresistor to decouple the row or column line from the voltage signal line. A single light source may be used to illuminate the coupling photoresistor of one conductor and the decoupling resistor of the preceding conductor simultaneously. The illuminating means may be light-emitting diodes driven by an electrical driver circuit, or a self-scanning gas discharge tube. The photosensitive devices may be arranged in groups, with an extended light source arranged to illuminate the photoresistors of a group simultaneously.
