Abstract: SUMMARY Press table insert for a coating press for multi-side film coating of form boards with a press table (1) which can be moved into the coating press, and which is equipped with numerous individual carriers (5) for taking up the workplaces (13) which are to be coated, whereby the individual carriers (5) can be moved horizontally on the press table (1) within their ranges of movement (10) for taking up the workpieces (13), whereby the height of each individual carrier (5) is shortened during the pressing process. A process for multi-side film coating of form boards is envisaged too. Thereby the film which is to be processed is first of all heated and then coated onto the boards by applying vacuum and pressure. The workpieces (13) which are to be coated are placed with mutual separation on the individual carriers (5) and thereafter the individual carriers (5) which are located in the peripheral regions of the workpieces (13) are shifted within their ranges of movement (10) such that the affected individual carriers (5) are set back with respect to the edges of the workpieces (13).  After moving the press table into the press chamber, the distance between the workpieces and the press table support is reduced for the duration of the vacuum drawing period (see Fig.1).

Title: Method for purifying alkali metal silicate solutions
Inventor: DADE-FIGUEROA TANYA
IPC: C01B33/20
Filed: 1999-04-14
Abstract: A method for purifying commercial alkali metal silicate solutions involves passing the alkali metal silicate solution through a nanofiltration device having a membrane with a molecular weight cutoff of between about 400 to about 3,000 daltons. Preferably, the molecular weight cutoff is between about 400 and about 1,000 daltons and, more preferably, between about 400 and about 800 daltons. In this way, a large portion of impurities in alkali metal silicate solutions, which tend to become associated with higher molecular weight silicates, can be removed. A pressure differential may be used to drive the solution across the device, from which a permeate is withdrawn as a purified alkali metal silicate solution. The retentate from the device is preferably recycled to the feed alkali metal silicate solution to form a mixture, and the mixture is introduced to the nanofiltration device.  Two or more devices, of decreasing molecular weight cutoff, may be used in series to obtain a more concentrated form of a purified silicate solution. When two devices are used, the second device has a molecular weight cutoff sufficient to allow water molecules to pass but to retain most of the remaining molecules. In order to achieve this, a molecular weight cutoff of approximately 100 to 600 daltons and, preferably, from about 150 to about 400 daltons, is suitable.

Patent CA-2346825-A1 (CA)
Title: Method for production of stroma-free hemoglobin
Inventor: VANDEGRIFF KIM D
IPC: A61P7/08
Filed: 1999-10-15
Abstract: The method employs a commercially-available blood cell separator comprising a computer-controlled centrifuge (2) having a rotor (24) into which a blood processing bag (6) containing donor blood is placed. Once the blood is collected, the process is performed entirely within the enclosed centrifuge bowl, preferably in situ at the donor collection site. In the first step, the blood is centrifuged to separate the plasma from the cellular components.  After isolation of the red blood cells from other blood components, the red cells are washed with normal saline or other solution. The red blood cells are then lysed by hypotonic shock to separate the red cell membranes (stroma) and the lysate is collected in a sterile container (44), leaving only the stroma in the centrifuge bowl. The final product can be used as raw material for any of the hemoglobin-based oxygen carriers currently being developed as red cell substitutes. All of the steps are performed within a processing container or blood bag (6) in the bowl centrifuge to minimize handling and maintain sterility. A method for preparing a modified hemoglobin solution incorporates the steps for producing stroma-free hemoglobin, then adding pre-measured reagents to react with the solution and filtering the solution.

Title: Spare wheel carrier
Inventor: NEWBILL ANTHONY J
IPC: B60R9/06
Filed: 2001-10-02
Abstract: A spare tire carrier for securement to an end segment of a vehicle bumper and having a swingable arm for travel about horizontal and vertical axes to relocate a spare tire away from the rear of a vehicle and subsequently downward into ground contact. A bracket on a bumper attached mounting plate pivotally carries an arm actuator including oppositely threaded shafts and a sleeve thereon. A ratchet drive imparts rotational movement to the sleeve in a selected direction to either lift or lower the arm and spare tire thereon in a controlled manner and additionally prevents random vertical movement of the arm during vehicle travel. Locks engageable with the bracket and the arm prevent horizontal and upright travel of the arm when the vehicle is underway. The carrier may include a bracket, attachable to a hitch or vehicle frame, with a base plate at its outer end to support the carrier mounting plate. A modified preferred carrier includes an electrical linear actuator to control the carrier arm. The arm is secured by a latch assembly with multiple locks. A support block on the arm facilitates wheel positioning.

Title: Dock levelers
Inventor: PEDERSEN PAUL
IPC: B65G69/28
Filed: 2001-12-21
Abstract: A dock leveler has a support with a deck pivotally secured to the support at one end for movement between a stored position and an elevated position. A deck lip is pivotally connected to the deck assembly for movement between a pendant stored position and a bridging position projecting from said deck assembly. A lift mechanism acts on said deck assembly to lift it toward the elevated position and a lip operating mechanism operatively connected to the lip moves it from the pendant position to the bridging position. A latch holds the lip in the bridging position. The latch releases the lip upon relative movement between the lip and the deck assembly and has a yieldable connection to permit limited pivotal movement between said lip and said deck assembly upon application of a rearward force from a vehicle to allow the lip to move to an unlatched position.
