Patent CA-2205122-A1 (CA)
Title: Hydrogen peroxide pickling of stainless steel
Inventor: LEEKER JERALD W
IPC: C23G1/08
Filed: 1997-05-12
Abstract: A process for removing scale from stainless steel using an aqueous solution containing hydrogen peroxide and an inorganic acid, i.e., hydrochloric or sulfuric acid. A hot rolled or annealed stainless steel strip (10) covered with scale is immersed into hot inorganic acid contained within pickling tanks (12) and (14). Thereafter, the strip may have residual amounts of tightly adherent scale (11). This scale is activated by a solution containing the inorganic acid and hydrogen peroxide applied to the strip such as by a spray header (16) extending completely transversely across and positioned above the strip and another spray header (18) extending completely transversely across and positioned below the strip. It may be desirable to pass the activated strip through the hot inorganic acid again and reactivate the strip at very high line speeds to insure complete removal of scale from the strip. Any hydrogen peroxide spray dripping from the strip is collected on a catch pan (30) and flowed into a tank (28). Preferably, the collected spent aqueous solution containing the inorganic acid and spent hydrogen peroxide is disposed in the pickling tanks. The aqueous solution aids in the removal of any residual scale and smut remaining on the strip thereby improving the cleanliness of the pickled strip.

Patent CA-2205933-A1 (CA)
Title: Push back storage assembly
Inventor: HALDIMANN HANS-RUDOLF
IPC: B65G1/06
Filed: 1996-10-07
Abstract: In a push back storage assembly, each shelf channel is pro-vided with a conveyor that comprises a continuous moving conveying member. The goods to be stored are non-positively received on the top of the conveying member. In the region of the unloading end of the shelf channel, a stationary slide member is provided, whose active length corresponds to 0.8- to 1.2-times of the mean brake-less running-out distance of the conveying member set in motion by the removal of goods. The frictional contact between conveyor mem-ber and pallet is released in front of the active length of the slide member. Thus, the non-positive connection between conveyor member and pallet is released during unloading of the frontmost pallet before the latter one is completely removed. Thereby, a safe and gentle slowing down of the moving conveyor member is en-sured, without the danger that any goods received in the shelf channel overrun the end thereof.

Patent CA-2232606-A1 (CA)
Inventor: HALE DAVID L
IPC: B60K28/10
Filed: 1998-03-19
Abstract: Devices and methods for preventing pull away or drive away incidents. The preferred devices can be retrofitted to critical gas pipes on fuel trucks or gas tanker trucks. A version of my invention can be readily employed with conventional automobiles. Through my system a vehicle engine cannot start or continue to run until a proper disconnection is made from a fueling or refueling source. The preferred protection device comprises a rigid, frame having a base portion connected to a gas pipe with spaced apart clamps. An elongated arm pivotally extending from the frame terminates in a blocking plate. The blocking plate can be user-deflected to either block access to the gas connection, or to expose it. When disposed in the blocking position, the arm activates a spark-proof ignition switch, which enables the ignition circuit in the vehicle being fueled or loaded. When the blocking plate is deflected away to expose the gas connection, ignition is interrupted or prevented by the switch and the vehicle's engine cannot start or continue to run. After disconnecting the hose properly, the ignition circuit is reestablished by the switch concurrently with the return of the blocking plate. I have adapted the concepts of my invention for ordinary automobiles to prevent pull away incidents at gasoline stations.

Title: Golf shoes with aligned traction members
Inventor: GELSOMINI PAMELA A
IPC: A43B13/26
Filed: 1998-08-17
Abstract: An improved golf shoe and sole is provided. In a preferred embodiment, a pair of golf shoes comprising a right shoe and a left shoe, the right shoe having a different arrangement of traction elements on the sole thereof than the left shoe. For right-handed golfers, the sole of the right shoe has a greater number of axial traction members which are aligned with an edge of the sole than transverse traction members which are positioned transverse to the edge of the sole. The right shoe accordingly resists pivotal motion. The left shoe has a greater number of transverse traction members than axial traction members so as to allow pivotal motion. The golf shoes accordingly allow the golfer to make a fuller back swing and to follow through more completely on the power stroke. The relative number of axial and transverse traction members on the left an right shoes may be reversed for left-handed golfers.
