Abstract: ABSTRACT                    (Figure 3 refers) A hot  air  drier  has a  heat  exchanger  (25) for  transferring heat to a first flow path (45) from a second flow path (30). The first flow path (45) has a blower unit (14) and an electrical heater (22) for pre-heating outside air and discharging it into a confined space where clothing or  body  drying  is carried out. The humidified air is drawn out of the space  and into the second flow path (30). A motor  (40)  controlled  by  a  temperature  or  humidity  detector  (70 operates a pair of fan impellers (41,42) at the entries of respective passages  through  the heat  exchanger.  During  a start-up phase the motor (40) is not operated and a by-pass circuit allows the blower unit  (14)  to re-circulate air  through the confined space so that the  air  temperature  rises  rapidly  to  optimum  drying  conditions prevail.The  motor  (40)  is  then  operated. The  drier  operates economically  without  discharging  hot  humidified  air  into  the surrounding room.

Patent CA-2065050-A1 (CA)
Title: Fluorescent-lamp leadless ballast with improved connector
Inventor: VAN WAGENER RAYMOND H
IPC: H01R13/66
Filed: 1992-04-03
Abstract: A half-connector body has lateral ears that fit in small notches in the ends of the side walls of a ballast can, preferably at the top. An end wall, if present, traps the ears longitudinally in the notches; resilience of that wall, and of its attachment to the can bottom, enhance tight longitudinal fit. The half connector (a receptacle) presses against, and partly protrudes through an orifice in, the end wall (if present).       Outside the ballast, in a new fixture, a jack slides freely in the receptacle to make wiring-harness connections.      The jack has a ratchet-like manually operable hook to secure the jack until manually released. Each contact or lead in either half connector is preferably provided with individual strain relief by permanent deformation (as for example using a die punch) without heating or plastic flow) of the connector wall inward, to displace material irreversibly around the wires. In either the jack or receptacle, cylindrical female contacts make smooth wiping contact with bared ends of standard fixture wires held in the opposite half connector, serving as pin contacts. If the female contacts are in the jack, a person may replace conventional ballasts with this new one, by cutting and baring the old harness wires and inserting them individually into the receptacle. Alternatively, for field retrofit a jack can be supplied, e.g. with poke-in wiring.

Abstract: A pseudo-synchronous fast transfer handshake protocol compatible for use on a VME backplane bus (22) having a master functional module (300) and a slave functional module (200) logically interconnected by a data transfer bus. The data transfer bus (22) includes a data strobe signal line (D50, D51) and a data transfer acknowledge signal line (DTACK). To accomplish the handshake, the master (300) transmits a data strobe signal of a given duration on the data strobe line. The master then awaits the reception of a data transfer acknowledge signal from the slave module (200) on the data transfer acknowledge signal line. The slave then responds by transmitting a data transfer acknowledge signal of a given duration on the data transfer acknowledge signal line.
Patent CA-2066838-A1 (CA)
Inventor: IVRI YEHUDA
IPC: B41J2/015
Filed: 1992-04-22
Abstract: The present invention provides an ink-jet ejection device which is capable of ejection or ink (including hot melt ink) jet frequencies greater than 50,000 Hz.  A cantilevered beam of selected shape is mounted at its base to a piezoelectric element which oscillates the base.  The beam is shaped so that its moment of inertia is reduced toward its free end.  The element is activated by an oscillating electrical signal the frequency of which is equal to or close to a natural frequency of oscillation of the beam.  In the preferred embodiment herein a third or higher modal frequency is utilized.  Because of the structural configuration of the cantilevered beam and the selected frequency of oscillation thereof, the tip of the beam ocillates over an amplitude which is significantly greater than the oscillation amplitude of the base.  The beam is highly damped and made of low density material so that the tip amplitude is extremely responsive to variations in the base amplitude.  The tip of the beam is provided with an aperture which is preferably tapered in cross-section.  One opening of the tapered aperture is in fluid communication with a reservoir of ink and the other opening of the aperture is positioned at an appropriate distance from a recording medium such as paper towards which individual droplets of ink from the reservoir are to be propelled.  When the tip amplitude is above a predetermined threshold  the solid-fluid interaction between the tapered aperture and the ink causes a drop of ink to accelerate through the aperture and be ejected upon each excursion of the tip of the beam toward the printing media.

Inventor: LAWLOR MATTHEW P
IPC: G06Q20/10
Filed: 1990-12-10
Abstract: A practical system (50) and method for the remote distribution of financial services (e.g., home banking and billpaying) involves distributing portable terminals (54) to a user base. The terminals (54) include a multi-line display (102), keys "pointing to" lines on the display (108), and additional keys. Contact is established between the terminals (54) and a central computer (52) operated by a service provider, preferably over a dialup telephone line (62) and a packet data network (56). Information exchange between the central computer (52) and the terminal (54) solicits information from the terminal user related to requested financial services (e.g., for billpaying, the user provides payee selection and amount and his bank account PIN number). The central computer (52) then transmits a message over a conventional ATM network (66) debiting the user's bank account in real time, and may pay the specified payees the specified amount electronically or in other ways as appropriate. Payments and transfers may be scheduled in advance or on a periodic basis. Because the central computer (52) interacts with the user's bank as a standard POS or ATM network node, no significant software changes are required at the banks' computers. The terminal interface is extremely user-friendly and incorporates some features of standard ATM user interfaces so as to reduce new user anxiety.

Title: Amplificateur a guide de lumiere
Inventor: ARMITAGE JONATHAN R
IPC: H01S3/10
Filed: 1991-07-18
Abstract: Amplificateur à fibre optique (50), comprenant une fibre optique monomode de SiO2-Al2O3-GeO2 (52) dopée à l'Er3+. Il est pompé par des sources optiques de 1,55 µm et 1,47 µm (54 et 56) dont les sorties optiques sont combinées par un coupleur optique (58), puis transmises à la fibre (52) par un deuxième coupleur optique (50). Une source de signaux optiques à amplifier (62) est également couplée à la fibre (52) par l'autre coupleur (60). Les ions Er3+ produisent un schéma d'émission laser à trois niveaux présentant une crête de fluorescence à environ 1,53 µm. L'amplification à faible bruit de signaux optiques dans la queue de grande longueur d'onde du spectre de fluorescence, avec suppression des ASE (émissions spontanées amplifiées) dans la longueur d'onde de crête des spectres de fluorescence, s'obtient comme suit.  La pompe 1,47 µm produit une amplification à faible bruit du signal optique mais amplifie de préférence la source de pompage 155 µm. Le signal de pompage amplifié 1,55 µm fournit ensuite la puissance de pompage pour l'amplification du signal optique tout en supprimant les ASE, étant donné que sa longueur d'onde est supérieure à celle de la crête de fluorescence.
