Abstract: LOAD BALANCING MECHANISM                         ABSTRACT           A  load  balancing  mechanism  (10)  disclosed includes an  arm  (12) including first and second arm portions  (14,26).   A support post  (22)  is rotatable about its vertical axis A and supports arm (12) by first arm portion  (14)  for pivotal movement  in a vertical plane and also for rotational movement about axis A. First arm portion (14) includes parallel spaced members (16,16')  defining a parallel  linkage arrangement.   A piston and cylinder balancing arrangement (38) connects post (22) and first arm portion (14) allowing upward and downward pivotal movement of arm (12) and is responsive to such upward and downward pivotal movement to provide balancing of a load thereon.   The second arm portion (26)  can be longitudinally moved relative to a second mount  (32)  to increase or decrease the length of arm (12)  without having to change the  force applied via balancing arrangement (38) to maintain balancing of the load.

Patent CA-2052475-A1 (CA)
Inventor: ONO KATSUHIRO
IPC: H01J35/10
Filed: 1991-09-30
Abstract: In a rotary-anode type X-ray tube, a rotary-anode is fixed to a cylindrical rotary structure, and a columnar stationary shaft is fitted in the rotary structure.      A gap is formed between the rotary structure and the stationary shaft. The gap is filled with a liquid metal lubricant. Spiral grooves are formed in part of the outer surface of the stationary shaft to form a radial sliding bearing between the stationary shaft and the rotary structure. Spiral grooves are formed in the end faces of the stationary shaft to form a thrust sliding bearing between the stationary shaft and the rotary structure. A recess is formed in the stationary shaft to communicate with gaps in the radial sliding bearing.      A lubricant storage chamber for storing the liquid metal lubricant is formed in the stationary shaft along the center axis. The storage chamber communicates with communicating holes which radially extend to be open to an outer surface region, of the stationary shaft, in which no spiral grooves are formed. With this structure, a sufficient amount of liquid metal lubricant required for a long-term operation of the sliding bearings can be stored in the X-ray tube, thereby maintaining a stable dynamic pressure type sliding bearing operation for a long period of time.

Patent CA-2070000-A1 (CA)
Inventor: WOEHR PETER
IPC: H04Q11/06
Filed: 1992-05-29
Abstract: The starting point are known space/time switching networks. The technical problem is that the capacity of a switching network could be increased by increasing the clock frequency. However, changing all interfaces, which is necessary for this, is only possible over a very long term. A transition solution is required which allows the gradual exchange or further extension using new interfaces.   The basic concept is the use of switching elements, the inputs and outputs of which can be switched individually between two transmission rates. Example: a frame structure which is based on the lowest transmission rate is used as a basis. Within such a frame, signals with the highest transmission rate can also be temporarily stored and time-converted. Provision is made for 4 Mbit/s and 32 Mbit/s. The advantage is that it is easily possible to combine several channels into higher-capacity connections (N x 64 Kbit/s).   The higher transmission rate is only used when actually required. This reduces the power dissipation and the interference radiation. <IMAGE>

Title: Paint denaturant
Inventor: CORY MICHAEL
IPC: C09D7/00
Filed: 1992-06-23
Abstract: This invention relates to a process for detackifying and dispersing paint solids for example obtained from paint overspray in enclosed areas such as paint spray booths.      The process comprises contacting an oil-in-water emulsion with an aqueous solution whereby the oil-in-water emulsion is destabilised. On subsequent contact of paint particles with the aqueous solution comprising the destabilised oil-in-water emulsion, the paint is adsorbed on to destabilised emulsion particles. The process provides an effective method of denaturing paint over-spray which is easily handleable and effective over a wide range of paint compositions.      In one embodiment of the invention, the oil-in-water emulsion comprises a latex.

Title: Apparatus for adjusting the center of a collet
Inventor: KANAAN ROGER J
IPC: B23B31/02
Filed: 1992-10-02
Abstract: The center of a collet (30) having a plurality of individual gripper members (32) resiliently spaced apart in an annular array and operated on by a frustoconical surface (14) can be adjusted by displacing some of the gripper members (32) more than others of the gripper members (32) parallel to the axis with which both the annular array and the frustoconical surface (14) are nominally concentric. This causes the frustoconical surface (14) to produce greater radial displacement of some of the gripper members (32), thereby shifting the center of the collet (30) transverse to the above-mentioned axis. An element (90) transversely moveable relative to the axis causes displacement of some of the gripper members (32) more than others. <IMAGE>

The Test label has an number of information conveying fields which include a machine-readable code that provides a unique identification code for tracking and sorting the specimen. The Test label also includes a second machine-readable code which indicates the test to be performed on the specimen.The machine-readable code format allows the specimens to be sorted by automated machines. The machine-readable codes can also be used in conjunction with a machine-readable shipping bin code to produce a waybill for shipping (and receiving) the specimens to a remote laboratory facility. The system also includes the capability of determining the number of Test labels which are required for a particular specimen, so that the printing of unnecessary labels is minimized.
