Holster (FIGS. 1, 5, 8) for a truncheon (28, 40-42, 54-56), the holster being a unitary folded inflexible sheet which is folded along a front portion (33) and having meeting edges along a rear portion (14), and a transverse screw-and-nut combination (51-53) connecting the two folded portions of the sheet to provide an adjustment to the clamping action of the holster to the truncheon. An optional k...

For gas phase polymerization reactions in the presence of an unsupported polymerization catalyst, there is provided a process for introducing a liquid catalyst so as to provide a resin particle lean zone such that the average particle size of the resin produced ranges from about 0.01 to about 0.06 inches.

The invention provides a process for producing a polyethylene homopolymer, copolymer, or terpolymer comprising introducing ethylene and optionally at least one alpha olefin having 3 to 18 carbon atoms in a reaction zone containing a metallocene polymerization catalyst under polymerization conditions in the presence of an amine-containing antistatic agent.

Bus interface units (BIUs) (54) perform fault detection, identification, and reconfiguration for all information transfers between redundant central processing units (CPUs) (56) and memory or input/output (I/O) (57A-C) in a mesh interconnected array of a highly reliable fault-tolerant computer system. Errors are detected by self-checking within the BIUs, signal parity checks by the BIUs, cross cha...

A coupling construction between an extended-nip roll including a non-revolving central axle supported by bearings which permit angular deflection of the non-revolving axle and a backup roll. Loading members are mounted on the non-revolving axle for pressing a loading shoe toward the backup roll. The extended-nip roll includes a flexible glide-belt mantle whereby a paper web or board web passes thr...

A sensor for use in a sensor dispensing instrument so that fluids can be tested when the sensor is ejected from within a sensor cavity of a sensor pack sealed by a foil. The sensor has a generally flat, rectangular shape and is formed by a base and a lid. The sensor has a perpendicularly extending longitudinal and transverse axes. A rear end of the sensor has a notch that is engaged by a knife bla...

A gear case assembly and lubricant retaining device therefore wherein the assembly includes a gear case having a hub and/or shaft receiving opening therein and a lubricant retaining device extending toward the interior of said case to reduce lubricant flow through said opening. A part of said lubricant retaining device acts as a diverter to restrict lubricant flow toward said opening and consequen...

The battery charging circuit has a DC rectifier for conversion of the AC mains input and a terminal compartment for battery connection. A dual element LED (44) provides a two-colour independently switchable display and is controlled by three transistors to indicate the circuit condition at any time. The LH light element in the LED (44) is lit via the monitor transistor (38) and switching transisto...

The magazine handles empty and filled potato boxes and incorporates a loading and storage station for a collector (1). The loading and storage station (10) loads the empty boxes directly from the ground (11) and stores them. The magazine also has a filling and discharge station (12) for receiving the empty boxes, filling them and discharging them directly onto the ground.

Disc filter includes a trough (1) for a liquid to be filtered and at least one filter disc (2) mounted on a shaft (3) being rotatable in a definite direction. Each filter disc is composed of filter sectors (4'). Each sector (4') is in fluid communicaton with a channel extending along the shaft for withdrawal of filtrate from the filter sector (4'). Each filter sector has straight defining leading ...
