Title: Car body surface treatment device
Inventor: HECKMANN NORBERT
IPC: B05C3/09
Filed: 1994-02-09
Abstract: In order to create a simple car body surface treatment device, a car body is introduced into and removed again from the treatment bath (11) simply by being rotated by a rotating device (2), at the same time as another car body is pushed onto and secured to said rotating device or conveyed past said device. The car body is fixed to a loading carriage (5) and is pushed by means of some driven rotary rollers (3a) onto the rotating device (2). By means of fastening devices (4a, 4b) the loading carriage (5) is detachably secured to the car body on the rotating device (2). By rotating through 180° around an axis of rotation (7), the rotating device (2) dips together with the car body over its tail or front side into the treatment bath (11). While one car body is submerged, another loading carriage (5) together with a car body fastened thereon may be conveyed by the driven rotary rollers (3b) past the rotating device (2) for subsequent treatment, over the top surface of the rotating device (2).

Patent CA-2165801-A1 (CA)
Inventor: VITERBI AUDREY
IPC: H04B1/7115
Filed: 1994-06-22
Abstract: A method and apparatus for decoding an orthogonally encoded data signal in a noncoherent receiver system. The method is referred to as dual-maxima metric generation. It comprises the steps of sequentially searching for a maximum energy level in each of two subsets of a given set of symbol indexes and associated energy levels and calculating a difference of the two values to form a soft decision output value. The two subsets are identified by the binary value (either "0" or "1") of a given digit of the binary equivalent of the symbol index. The soft decision output value reflects a measure of confidence of the value of the corresponding digit of the original signal. The dual-maxima generator sequences through the steps one time for each binary digit of the original signal. The method allows the correlated energy from multiple receivers to be combined before the decoding of the signals, thus further reducing the complexity of the circuitry and improving the performance of the decoder.

Patent CA-2171656-A1 (CA)
Title: Card Reader
Inventor: WONG YIU KONG
IPC: G06K13/06
Filed: 1996-03-13
Abstract: A card reader stores the energy imparted by a user inserting a card into a slot. When the card is fully inserted, a release mechanism is triggered and the stored energy moves a read head over a coded stripe. In the preferred embodiment, a torsion spring mounted on a carriage winds about an axle. The axle has a gear at one end which engages a rack fixed on the base of the reader. The gear and axle rotate as the carriage is moved relative to the reader, thereby winding the torsion spring and storing energy. A set of ratchet teeth mounted on the base prevents the return of the carriage before the card is fully inserted into the slot. The reader can also accommodate reading and writing to smart cards.

Abstract: Cette invention se rapporte à un mécanisme et à un dispositif d'administration, qui permettent la libération périodique passive d'un médicament ou d'un ingrédient actif, tout en évitant la nécessité de recourir à des sources d'énergie externes et/ou à des contrôleurs électroniques. En tirant profit des variations des systèmes chimiques, on peut modifier le pH d'une solution, d'un médicament, d'un agent facilitant ou d'un agent de solubilisation, ce qui a pour résultat de faire varier la capacité d'un ingrédient actif à pénétrer dans l'organisme par voie transdermique, lors de son administration. Le pH d'une solution peut être amené à varier entre des valeurs comprises entre 2 et 10, par les réactions de réduction et d'oxydation (redox) de sels, tels que les permanganates, les iodates, les sulfates, les chlorates ou les bromates. Lors de l'activation, les conditions du système d'administration commencent à varier, ce qui a pour conséquence de faire varier la libération de l'agent actif dans l'organisme.

Title: Nonazide gas generating compositions having heat absorbing additive
Inventor: LYON LYMAN R
IPC: C06B31/12
Filed: 1995-07-11
Abstract: Nonazide gas generating compositions are formed from a nonzazide fuel, an oxidizer, and a heat absorbing additive in the form of a glass compound having a softening point in excess of approximately 590 ~C (1094 ~F). The additive effects a reduction in the combustion temperature of the gas generant, thereby resulting in inflating gases having a reduced content of toxic gases such as NOx and CO. The gas generants are therefore nontoxic and useful for inflating a vehicle occupant restraint system.
