Patent CA-2058796-C (CA)
Inventor: KAMAGATA EIJI
IPC: H04L12/933
Filed: 1992-01-06
Granted: 2001-10-09
Abstract: A cell switch and a cell switch network with a simplified cell switch testing such that the testing processes can be carried out quickly and easily. The cell switch includes a dummy cell generation circuit for generating dummy cells in correspondence to the output transmission paths; and an output control circuit for selectively outputting the dummy cells to the output transmission paths when a test of the cell switch is indicated by an externally provided control signal. In a cell switch network In which the cell witches are inter-connected in a form of a multi-step configuration, the cell switches belonging to each step in the multi-step configuration of the cell switch network is tested sequentially, by supplying the control signal to each of the cell switches belonging to each step in the multi-step configuration of the cell switch network sequentially, in a reverse order of steps in the multi-step configuration of the cell switch network.

Title: Digital communications systems
Inventor: MCCABE DAVID JAMES
IPC: A43D21/00
Filed: 1992-02-11
Granted: 1998-12-01
Abstract: Corruption in digital data communications systems is detected, at the receiving end, by taking a number of samples of the received signal within each bit period.   Flip flops (4, 7 and 8) are used to take samples from the digitised received signal as follows: flip flop (4), a mid bit sample indicative of the value of the centre of the bit; flip flop (7), a pre-mid sample taken within the bit period before the mid-bit sample; and flip flop (8), a post-mid sample taken within the bit period after the mid-bit sample. Gating circuitry (23, 24, 25) is used to analyse the three samples and give a "good" or "bad" output signal to register 11 as a result of the analysis. Corruption is judged to be present if any one of the samples has a different value to the others.

Title: Method and device for solid phase microextraction and desorption
Inventor: PAWLISZYN JANUSZ B
IPC: G01N30/06
Filed: 1991-04-02
Granted: 2001-08-07
Abstract: A device for carrying out solid phase microextraction is a fiber (6) contained in a syringe (4). The fiber can be solid or hollow. The syringe has a barrel (8) and a plunger (10) slidable within the barrel, the plunger having a handle (12) extending from one end of the barrel. A hollow needle (18) extends from an end (16) of the barrel opposite to the plunger. The fiber is contained in the needle. When the plung-er is depressed, the fiber extends beyond a free end (28) of the needle and when the plunger is in a withdrawn position, the fiber is located within the needle.  The syringe protects the fiber from damage. When it is desired to analyze a sample in a bottle having a septum, the needle is inserted through the septum and the plunger is de-pressed so that the fiber will extend into the sample. After one or two minutes, the plunger is moved to the withdrawn position so that the fiber will return to the needle and the syringe is withdrawn from the sample bottle. The syringe is then inserted through a septum in a gas injection port of a gas chromatograph. The plunger is again depressed so that the fiber will extend into the gas chromatograph and an an-alysis of the components on the fiber is carried out. Then, the plunger is moved to the withdrawn and the syringe is withdrawn from the injection port.  Previously, sam-ples were analyzed using liquid-liquid extraction or using cartridges. Both of these methods are relatively expensive and time consuming. Both of these methods also require the use of solvents which can be difficult and expenssive to dispose of.

Title: Sleeve for increasing retention value of a screw
Inventor: LEIBHARD ERICH
IPC: F16B13/12
Filed: 1992-12-04
Granted: 2000-07-18
Abstract: The retention value of a screw previously inserted into a wooden railroad tie is increased by an axially extending sleeve (20) having an external thread (24) and an internal thread (25). The thread revolutions of the internal thread (25) are offset axially by half (h) the thread pitch (H) of the external thread (24). due to this offset of the threads, the screw is positioned in the sleeve so that its threads are located between the external thread revolutions affording a new retention, while the external thread (24) seats within the thread previously formed in the wooden railroad tie by the screw.

Title: Multi-function shower head
Inventor: WARD IRVING
IPC: B05B1/16
Filed: 1991-08-08
Granted: 2001-10-09
Abstract: The instant invention is, in broad aspect, a shower head that provides a series of spray effects. The object of the instant inven-tion includes to efficiently provide a shower head user with a varie-ty of spray effects and to reduce the complexity of the multifunc-tion shower head. The shower head (10) includes an inlet port to establish fluid communication with a source of water and at least two outlet ports (58 and 60) to direct a spray with various effects to the user. A pushrod (36) disposed in fluid communication between the inlet port (56j and the outlet ports (58 and 60) selectively opens the outlet ports (58 and 60) to allow the user to continuously select any combination of spray effects, which may include a continuous stream or a pulsating jet. The pushrod (36) is actuated by a rotat-ing cam ring (16) operated by the user. The cam (16) moves the pushrod (36) transversely across the inlet port (56) and, under con-trol of the user, directs water from the inlet port (56) to the outlet ports (58 and 60). The cam ring (16) maintains the pushrod (36) in the selected orientation.

Abstract: The installation for the parking of motor vehicles has one or several autonomous parking units (S), shaped as sectors of a circle on plan.  Each such unit has its own mechanical conveyor system, comprising a car lift (10) with a vertical guide (11) located in the region of the apex of the sector, and a cantile-vered vehicle platform (12) that pivots across the angle enclo-sed by the sector.  Within the parking unit (S) the lift (10) provides the vertical and horizontal transport of the vehicles between a drive-in/drive-out level (1) and the parking spaces on parking levels below and/or above level (1); in addition, the lift (10) is equipped for the radial transfer of vehicles. Each parking unit (S) also has its own means for turning vehic-les in situ, e.g. one or several turntables or rotary platforms (8) at the drive-in/drive-out level (1).  A vehicle-standing area (9) on each turntable or rotary platform can be turned to a drive-in position and a drive-out position and can be aligned radially with the vehicle platform (12) of the lift. - A compu-ter-controlled installation of this type is very flexible and readily adaptable to a wide range of operational situations. After being parked, the vehicles can be driven out and leave the parking installation readily without reversing. Because of its modular design, the system is suitable not only for use in buildings that are circular on plan, but also, always with similar units (S), for other layouts to conform to local cir-cumstances.

Abstract: Un trocart (10) possédant une canule (22) et un boîtier (28) définissant un canal d'accès, est conçu pour recevoir un instrument chirurgical (26). Un clapet souple (36) situé dans le canal comprend des premieres parties (37) définissant un orifice (38) à travers le clapet (36) et des deuxièmes parties (39) situées à l'extérieur des premières parties. Les deuxièmes parties (39) sont pouvues d'une souplesse supérieure, de manière que, quand on introduit l'instrument (26) de façon désaxée, les deuxième parties (39) du clapet (38) se déforment avant les premières parties (39), ce qui provoque le déplacement de l'orifice (38) vers l'emplacement désaxé, sans déformation sensible. Dans un autre mode de réalisation, des leviers (54) venant en contact avec les premières parties (37) du clapet (35) peuvent être montés rotatifs sur une bague flottante (180), de façon à déplacer l'orifice pratiquement non déformé (38) vers l'emplacement désaxé. Un procédé associé consiste à déformer les deuxièmes parties (30) du clapet (36) sans déformer sensiblement les premières parties (37) dudit clapet (36), de façon à déplacer l'orifice (38) pour l'aligner axialement sur l'instrument (26). Un mécanisme (81) sert à protéger le clapet (36) d'instruments possédant des extrémités distales pointues.
