Patent CA-2211823-A1 (CA)
Title: Automotive screw jack
Inventor: ROTHBAUER THOMAS D
IPC: B66F3/10
Filed: 1997-07-29
Abstract: A screw jack (20) includes a strand (21) which houses a side gear (58) which, when rotated, turns a bottom gear assembly (67). An inner screw (73) is connected to the bottom gear assembly (67) and thus turns therewith. Because of an interaction with an outer screw (77), rotation of the inner screw (73) initially causes a tube assembly (24) to move axially relative to a hexagonally shaped sleeve (23). A hex nut (81) is attached to the lower end of the tube assembly (24) to prevent rotation of the tube assembly (24). The nut (81) threadably engages the outer screw (77) and at one stage during the use of the jack (20), the nut (81) also engages a shoulder (82) of the sleeve (23) so that upon continued rotation of the screw (73), the tube assembly (24) and sleeve (23) move axially together. A load bearing assembly (25) is carried at the top of the tube assembly (24) and is adapted to be positioned  under the frame or other component of a vehicle to be lifted. When the vehicle is being lifted, the jack (20) is allowed to tilt on selected of feet (48, 49, 50) positioned on the bottom of a base plate (22). The base plate (22) has a plurality of tabs (40) which are folded over edges (37) of a peripheral bottom plate (35) of the stand (21) to attach the base plate (22) to the stand (21). A bearing cup (71) positioned on the base plate (22) receives feet (72) of the bottom gear assembly (67) to floatingly position the bottom gear assembly (67) within the stand (21).

Title: A system and method for shearing or rotating an image using discrete cosine transforms
Inventor: HAJJAHMAD IBRAHIM
IPC: G06T3/60
Filed: 1996-01-29
Abstract: An image processing system for skewing or rotating an image includes an image acquisition device, first, second and third memories, a matrix multiplier, control sequencer logic and an output device. Image rotation is facilitated by performing a series of shearing operations on image data points representing the image in a spatial domain. A first shearing operation produces a first sheared image by shearing the image. A second shearing operation produces a second sheared image by shearing the first sheared image. A third shearing operation produces a third sheared image corresponding to a rotated image by shearing the second sheared image. For each shearing operation the image data points are transformed into DCT coefficients in a frequency domain using a discrete even cosine transform (DCT). Thereafter, skewed image data points are generated by taking a modified inverse discrete even cosine transform (IDCT) of the DCT coefficients using a modified IDCT basis function dependent upon either a horizontal or vertical offset.

Abstract: Syringes for medical and diagnostic purposes have a gripping strip on the syringe barrel as an abutment for when the plunger is pushed into the syringe barrel during the administration process. The connection of the gripping strip to the syringe barrel has to withstand high pulling forces during this process, of up to 100 N.            It is known to attach the gripping strip as a separate plastic part  firmly  to  the  syringe  barrel,  namely  by means  of a hollow-cylindrical seat (2) whose outside diameter is smaller than the inside diameter of the syringe barrel and in which there are moulded onto the outer surface catch elements (3) for a positive-locking operative connection to the syringe barrel, which has  an  internal  undercut complementary to the catch elements (3), it being possible to introduce into the interior of the seat (2) a securing ring (4) for maintaining the operative connection.            In order to reduce the manufacturing and mounting outlay, the securing ring (4)  is integrally connected via predetermined breaking points (5) in a non-securing position to the interior of the seat (2) and is displaceable into the securing position as the syringe barrel is placed over the seat (2), the outer surface of the seat (2) being constructed only in peripheral portions and in gaps therebetween the catch elements (3) for the positive-locking operative connection to the internal undercut of the syringe barrel being moulded on.

Patent CA-2244733-A1 (CA)
Inventor: CARSON DENNIS A
IPC: C12Q1/68
Filed: 1997-01-27
Abstract: An in vivo method for depleting mammalian cells of adenosine 5'-monophosphate (AMP) useful in the treatment of certain cancers is provided. According to the method, a population of cells is obtained from a host and assayed for loss of methylthioadenosine phosphorylase (MTAse) activity. MTAse catabolizes methylthioadenosine to adenine for endogenous salvage incorporation into the intracellular AMP pool. The preferred method for assaying loss of MTAse activity is a hybridization technique for detection of a homozygous loss of the gene which encodes with a therapeutically effective amount of an agent which inhibits the activity of adenylsuccinate synthetase, which converts inosine 5'-monophosphate to AMP, thus depleting the tumor cells of substrates for de novo AMP production. L-alanosine is the preferred ASS inhibitory agent for use in the method of the invention. The figure is a nucleotide sequence for genomic MTAse (SEQ. ID. No. 1) wherein the exons are underlined.

IPC: H04L29/08
Filed: 1997-05-06
Abstract: A method for selecting an electronic module from a plurality of at least two modules (M1, M2, M3) capable of emitting messages simultaneously, includes the steps of sending a general query message (ACTIVALL) to the modules, and selecting (AFI, SELECT-ID) the module having responded first, the modules, on receiving a query message (ACTIVALL, ACTIV), determining a random time interval (P) and sending a responding message (ID, R) when the said time interval (P) has elapsed. A module is set in idle position (IDL) when it receives a message (MESS) before the time interval (P) preceding the sending of a response (ID, R) has elapsed. The idle position (IDL) is at least characterized by the fact that one module does not respond, subsequently, to a complementary query message (ACTIV). This invention is particularly useful for contactless smart card readers and for terminals for electronic labels.
