Patent CA-1250401-C (CA)
IPC: B25C1/00
Filed: 1984-03-16
Granted: 1989-02-28
Abstract: A fastener driving tool has a motor (24) (Fig. 1) driven energy storing flywheel (26) and a reciprocating fastener driving ram (44). The flywheel has a metal peripheral surface that selectively engages a metal surface of the ram in order to drive the ram into engagement with a fastener (104) to be driven into a workpiece. Selective engagement occurs upon operation of a solenoid (84) to propel a thicker portion of the ram into the nip of an idler roller (28) and the flywheel closed together by movement of a safety yoke (23) engaging the workpiece (not shown), the movement being transferred to the roller (28) via a toggle linkage (64, 68). An elastic cord (52) returns the ram to a retracted position when the ram is disengaged by the flywheel, and a pair of elastic bumpers (48, 50) are employed to limit the travel of the ram in the direction of the retracted position and the direction of the fastener engaging position. The ram, bumpers and cords form a subassembly (48) that permits the ram, cord and bumpers to be removed from the fastener as a unit. The cord (52) is made relatively long to reduce the amount of stretch per unit length applied to the cord thereby to increase the life of the cord. The motor (224) (see Fig. 14) and flywheel may be rotated in opposite directions to reduce precessional forces but in any event, the motor is mounted to the rear of the tool and drives the flywheel through a flexible drive belt (30, 230) to provide for a well balanced tool.

Abstract: Transparent glass sheets comprising thereon titanium-nitride as the principal solar screening layer for reducing transmission of near infrared and, thereover, a layer of tin oxide of about 300 to 800 angstroms thick. The tin oxide layer serves to protect the titanium nitride from oxidation during hightemperature processing procedures, increases the abrasion-resistance, and, at roughly the midpoint of the 300 to 800 angstrom range, is useful in reducing the color and visible reflectivity properties of some titanium nitride films. In practice, some of the tin oxide, that is not required for physical protection of the TiN or visual effect, can be positioned between the nitride and the glass substrate.

Title: Method and reactor vessel for the fermentative preparation of polysaccharides, in particular xanthane
Inventor: OOSTERHUIS NICOLAAS M G
IPC: C12M1/20
Filed: 1987-06-08
Granted: 1993-01-26
Abstract: ABSTRACT For the fermentative preparation of polysac-charides, in particular xanthane, water, production medium (sugars, nutrient salts), and an inoculation material of a suitable aerobic bacterium are mixed in a reactor as reaction components, the production medium being exposed to fermentation while an oxygen-containing gas is being supplied. The object is to avoid the usual low yield of such a process and to reject an expensive and sensitive alternative construction (circulation tube). According to the invention, the reaction components are introduced into a reactor vessel in a circulating flow by means of Pumping means, which circulating flow comprises a rising flow and a descending flow which are separated from each other by one or more partitions disposed in the reactor vessel. The mixing is brought about because the rising flow and/or the descending flow is passed essentially in the form of a Plug flow through one or more static in-line mixers.

Title: Metropolitan area network arrangement for serving virtual data networks
Inventor: LIDINSKY WILLIAM P
IPC: H04L12/28
Filed: 1988-11-16
Granted: 1992-02-04
Abstract: METROPOLITAN AREA NETWORK ARRANGEMENT    FOR SERVING VIRTUAL DATA NETWORKS Abstract A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.
