Patent CA-2085196-A1 (CA)
Title: Tape cassette structure
Inventor: WATANABE MASARU
IPC: G11B23/087
Filed: 1992-12-11
Abstract: Abstract A cassette for accommodating a magnetic recording tape comprises a generally rectangular casing.  An erasure preventing member is accommodated within a detection hole in the casing for selective movement between retracted and projected positions.  This member has an outer surface that in the projected position closes the detection hole and lies flush with an outer surface of the rear wall of the casing, indicating that the tape is available for recording or erasure.  When the erasure preventing member is moved to its retracted position with its outer surface located inwardly from the rear wall, the cassette is in the condition in which neither recording nor erasure can be accomplished.

Title: Flexible screw for conveyors
Inventor: OHTSUJI MASAAKI
IPC: B65G33/04
Filed: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE A flexible screw for conveyors, which comprises a flexible rod and a polymer-coated cord helically wound on the rod, said cord comprising a core and a polymer layer formed on the core, and said core comprising a fiber bundle having a specific amount of buckling of not more than 0.3%.  When the screw is used for transporting containers, it can adapt itself to a drastic change in the surrounding temperature and can endure a great tension caused by the transport of heavy containers, since winding pitch of the cord is not easily widened and the disturbance of the pitch can be prevented.

Patent CA-2094319-A1 (CA)
Inventor: UNNO YOSHIHIRO
IPC: B60R16/02
Filed: 1993-04-19
Abstract: In a mobile communication system, a speech signal is transmitted without discontinuity even when transmission channels are switched during communication. A control circuit issues a control signal, in response to a switching timing of the transmission channels, to an initialization circuit. Theinitialization circuit initializes contents in a memory in a speech signal encoder circuit in response to the control signal. Because the memory contents in the encoder circuit are initialized with the switching timing of the transmission channels, the influence of previous speech codes, and hence the discontinuity, are eliminated.

Abstract: ABSTRACT      A rubber composition comprising the following components:          (A)  a rubber component comprising at least 50% by weight of  a styrene/butadiene copolymer rubber;          (B)  an azodicarboxylic ester compound represented by the formula              (I) wherein X is an alkyl of 3 to 8 carbon atoms, an unsubstituted or substituted phenyl, or an unsubstituted or substituted benzyl;          (C)  carbon black having a nitrogen absorption specific surface area of 100 to 250 m2/g and a dibutyl phthalate  absorption number of 110 to 170 ml/100 g;          (D)  sulfur; and (E)  a benzothiazole vulcanization accelerator.      This rubber composition shows a high loss factor (tan .delta.) in  a low temperature range, and besides shows a low loss factor in a high temperature range.  Therefore, the composition when applied to the production of automobile tires, achieves improved braking power on a wet road surface and on a  snow-covered or frozen road   surface, as well as a lowered rolling resistance during driving.  In addition, the strength characteristics of the composition are not lessened.

Title: Lead-acid battery of the absorptive mat type with improved heat transfer
Inventor: GERNER SCOTT D
IPC: H01M10/50
Filed: 1993-11-23
Abstract: Absorption mat lead-acid batteries poorly dissipate heat from the internal components of the battery (10) due to the air gap (35, 37) which exists between the plates (20) and the inner wall of the container (12). Improved thermal management of the battery (10) is achieved by filling the air gap (35, 37), an insulating gap, with a thermally conductive gel (40), such as a gel formed of fumed silica and sulfuric acid electrolyte.

Abstract: ABSTRACT COLOURED EXTRUDED STRIPS A strip formed at least partly of elastomeric material has at least a portion of its surface coloured by application of a coloured spray coating.   In order to provide a distinct boundary between coloured and uncoloured portions of the strip an integral tear-off bead projecting outwardly from the surface may be provided with the coloured spray coating being applied to one side thereof only.  If desired, two different coloured coatings may be applied, one to either side of the bead.   The strip is particularly suited for use as a vehicle weatherseal and may, therefore, be of composite construction with a flange gripping portion and a sealing portion.    The spray coating preferably consists of a polyurethane based finish utilising a blend of individual components which adheres to the surface of the strip yet maintains the strip's flexibility.

Abstract: HYPERPASTEURIZATION OF FOOD            ABSTRACT   Methods of treating liquid, semiliquid and solid foods to make them safer to eat and/or to improve the keeping quality of the products. Among the steps that can be employed are: the use of a biocidally active form of oxygen to reduce thepopulation of indigenous microbes, the removal from the food of indigenous gaseswhich may cause spoilage, the replacement of gases removed from the product with gases which are chemically inert or biologically sterile or both, and the asceptic packaging of the treated product. The selected process steps are carried out for a time and at a temperature sufficient to facilitate production of substantially more natural and safer foods than can be obtained if traditional methods of pasteurization are employed.

Filed: 1992-11-12
Abstract: 2123408 9309954 PCTABS00022 A printing ink comprises a clear, transparent, polymeric carrier material and uniform, colloidal size charged color particles evenly dispersed therein. The carrier and the particles are adhesively bonded to one another so as to form a matrix which can collectively respond to an externally imposed electrostatic field to promote co-movement of a "bite" of ink to an imaging medium without change of the bulk particle/carrier ratio. During the printing process, the ink is melted and exposed to electrostatically charged latent image areas on a heated image cylinder, resulting in the transfer of the ink thereto in proportion to the electrostatic field strength. The ink exhibits a relatively sharp liquid-to-solid transition, thereby enabling rapid ink solidification and complete transfer from the imaging medium to the relatively cool printing substrate. Also disclosed is a printing method and apparatus that facilitate continuous, variable and on-demand color printing in conjunction with the ink. Use of essentially monodispersed, color-coated, colloidal size, spherical particles in the ink results in excellent color purity and chromaticity range.

Title: Process for treating radioactive waste
Inventor: BEGE DIETMAR
IPC: G21F9/14
Filed: 1992-11-06
Abstract: Radioactive waste occurs for example in the form of contaminated powdery ionic exchange resin. This ion exchange resin is to be made suitable for final storage by reducing its volume as much as possible. According to the invention, this is performed by a process according to which the ion exchange resin is mechanically dewatered, the dewatered ion exchange resin is mixed with a calcium compound, is then dried with the addition of heat and after which, finally, the dry mixture is thermally treated at a pressure of less than 1000 hPa by heating up to a temperature in the range from 120 to 190°C. The ion exchange resin thereby loses its water absorption and swelling capability.        Ion exchange resins treated in this manner are processed with cement or bitumen to form blocks suitable for final storage.
