Patent CA-2147163-A1 (CA)
Title: Treating earthenware bodies
Inventor: MACMULLEN PAUL NEIL
IPC: C04B41/89
Filed: 1993-10-15
Abstract: A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellant material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellant material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.

Title: Device for securing equipment against theft
Inventor: SCHMOLL RAINER
IPC: E05B73/00
Filed: 1995-12-05
Abstract: A device for securing equipment against theft has a fastener for attaching the device to the equipment, an anchor for attachment to a cumbersome object, and a coupler for flexibly coupling the fastener to the anchor. The shape of the fastener is unimportant except that it must attach securely to the equipment and it must provide for a suitably rigid connection to the coupler. The coupler is a substantially planar solid body defining an aperture passing through the plane. The coupler attaches to the fastener such that the plane defined by the coupler is oblique to the plane defined by an adjacent surface of the equipment. The anchor is an elongated member having a fixed end for attachment to the cumbersome object and a free end defining a radial passage. The cross-section of the anchor is small with respect to at least one diameter of the coupler aperture and is adapted such that the free end of the anchor passes through the coupler aperture. A lock having a shackle adapted to pass through the passage in the free end of the anchor and through the aperture in the coupler secures the coupler to the anchor.

Title: Method and afterburner apparatus for control of highly variable flows
Inventor: STILGER JOHN D
IPC: F23C99/00
Filed: 1994-07-15
Abstract: Methods and apparatus are provided for destruction of volatile organic compounds ("VOC's") from process fumes having variable amounts of such VOC's wherein a nominal amount of the fumes are passed through an oxidizer (24) for destruction of the VOC's and the hot products from the oxidizer (24) are fed to an afterburner (30) that is principally made up of a matrix bed of heat resistant material. The heat from the oxidized gases heats the matrix bed. Fume flows exceeding the nominal flow are bypassed directly to an inlet port of the afterburner where they are passed through the matrix bed of the afterburner, which has been heated by the oxidized gases from the oxidizer (24) and are combusted into additional gaseous products in a combustion wave. The system allows for utilisation of the heat produced from the oxidation of the nominal flow for destructing fume flows that exceed the nominal flow.

Title: Multi-flail glass pulverizer
Inventor: ANDELA JAMES
IPC: B02C19/00
Filed: 1993-11-15
Abstract: The invention is a glass pul-verizer (6) in which two rotat-able flail assemblies (39 and 46) are housed within two contiguous drum-like housings (8 and 16), re-spectively. One housing (g) has an inlet (10) on one end and the other housing (16) has an outlet (20) located on an end furthest from the end adjacent the inlet. The housing (8) having an out-let (20) is longer than the other housing (16) thereby allowing the pulverized glass to exit the device in a relatively low speed and con-trolled manner. The flails (42) of the flail assemblies (39 and 46) are flexible and are secured to flat-bottomed slots (72) or spot faces located on the exterior of the shaft (32).

Patent CA-2181040-A1 (CA)
Title: Ion spray with intersecting flow
Inventor: COVEY THOMAS R
IPC: G01N30/72
Filed: 1995-01-09
Abstract: Liquid from a liquid chromato-graph or other sample source, prefer-ably assisted by a high velocity coax-ial gas jet, is sprayed through a cap-illary tube (40') producing a flow in a first direction of charged droplets (50'). A flow of heated gas (60), in a second direction different from the first direction, intersects the droplet flow at a region (64) upstream of an orifice (20'). The flows mix turbu-lently, with the second flow helping to evaporate the droplets to produce ions and helping to move the evapo-rating droplets toward the orifice (20'), providing a focusing effect. Ions are drawn through the orifice (20') into a mass analyzer and analyzed.  Alter-natively the flows of liquid and heat-ing gas can be directed toward each other and at right angles to the axis through the orifice, and the inhaling effect of the orifice can be used to draw droplets toward it, or a third gas flow can be used for this purpose. The heated intersecting gas flow typically provides an increase sensitivity (ion counts per second) of between 10 and 100 times. Heating the droplet plume also allows controlled desaturation of ions and an increase in the number of charges on them, without degrading the ions.

IPC: A61H33/00
Filed: 1996-07-16
Abstract: A hand-held shower attachment  (40)  with shower head  (44) contains a lever (64) which pivots around a transverse axis (66), with which lever (64) a valve spool (50) may be shifted from a neutral position in opposing directions. The hand-held shower attachment (40) is connected to a number of hose lines (78) which comprise a pressure-water supply hose, a return line and two control lines. By slewing the manual operating element (74), one control line in each case is connected to the pressure-water supply line, which opens a control valve in order to raise or lower a lifting plate of a bath lift. Rotating the manual operating element (74) around a vertical axis  (70),  causes the valve spool (50)  to be rotated by approx.  90° around its longitudinal axis,  as a result of which said valve spool  (50)  connects a water passage  (84) leading to the shower head (44), to the pressure-water supply line (80). The hand-held shower attachment (40) thus serves as a remote control unit for raising and lowering the lifting plate of a bath lift and has its own switching element for activating shower operation.
