The rotary table vacuum filter is a continuous filtration
unit designed to handle large flow rates. The horizontal orientation of the
rotary table enables a thick filter cake to form on the surface. The filter
features a uniquely designed cake discharge system, which uses an extraction
screw mechanism to remove the dewatered cake from the table and deposits it
into a hopper. The filter is an alternative to horizontal belt filters, rotary
drum vacuum filters, and filter presses. WesTech Engineering Inc. (Salt

provide a 95% reduction of harmful substances, such as vapors or gases leaking
from waste solvent jerricans due to the use of a filtering cartridge of
activated charcoal. The caps are delivered with fittings and ferrules for 1/8
in. and 1/16 in. tubing. JM Science Inc. (Grand Island, N.Y.).
series non-spill thermoplastic chemical transfer couplings are designed to meet
requirements for closed system transfer of chemicals and other fluids. The
couplings can be used with concentrated or diluted industrial chemicals,
fertilizers, herbicides, insecticides, fungicides, or pesticides when
transferring from bulk storage tanks, returnable containers, applicators, and
more. Applications include chemical dispensing systems, agriculture spray
application equipment, intermediate bulk containers, pulp and paper, sulfuric
acid, pH stabilization, industrial chemical transfer, and water systems. The
couplings are manufactured in 0.5-, 1-, and 2-in. sizes. They are available
with fluorocarbon, ethylene propylene diene monomer, and Kalrez seals, as well
as 316 stainless steel and Hastelloy spring options. A robust connection
safeguards the transfer and dispensing of hazardous and aggressive chemicals
with minimal spillage. Parker Hannifin Corp. (Minneapolis).

power/error and the other indicating inspection pass/fail. The system is
available in five cordset lengths, ordered separately; mounting brackets and
stylus are included with the cordset kit. Banner Engineering Corp.
SQ .2 range, designed for butterfly and ball valve automation, replaces the SG
.1 range. The new actuator size in the SQ .2 series more than doubles the
torque range. This expansion covers 50 to 2400 Nm. Advanced features and
benefits include adoption over a wider torque range without the need for a
gearbox. Sophisticated diagnostics and asset management enhancements include
additional temperature and vibration sensors. For enhanced positioning
accuracy, and an increased number of permissible starts per hour, an SQR
version for modulating duty replaces the SGR. Commissioning and operation of SQ
actuators are identical to the SA .2 multi-turn range. Both ranges are
available with simple AM or microcontroller operated AC integral controls. As a
result, controls are interchangeable, and at facilities where both product
series are installed, onsite device management is simplified. AUMA Riester
