Patent CA-2014593-A1 (CA)
Inventor: ONDERKA OSWALD
IPC: H01H3/16
Filed: 1990-04-12
Abstract: A safety door lock for a door of an electrical appliance to selectively enable or disable operation of the electrical appliance includes a longitudinally displaceable detent bolt mounted in a door of an appliance, the detent bolt including a free end having a detent recess, a door lock housing having an opening adapted for receiving the free end of the detent bolt, and a switching slide which is longitudinally displace-able along a longitudinal axis and which is mounted in the door lock housing.  The switching slide is oriented such that longitudinal displacement of the detent bolt toward the switching slide brings the detent bolt into engagement with the switching slide, the switching slide having a stub end adapted to engage with the free end of the detent bolt.          After engagement of the end of the detent bolt with the stub end of the switching slide, further longitudinal displacement of the detent bolt in a direction toward the switching slide causes movement of the switching slide to its "on" position.          A biasing means urges the switching slide toward an "off" position in which the appliance is disabled, and a detent means latches the free end of the detent bolt in a locking position within the door lock housing upon insertion of the detent bolt in the door lock housing and for locking the switching slide in its "off" position when the end of the detent bolt is not inserted in the door lock housing.  The detent means includes at least one releasable locking latch which clamps the stub end of the switching slide in the "on" position of the switching slide, to prevent longitudinal movement of the switching slide, and the locking latch is movable in a direction which is generally radial to the longitudinal axis.  A biasing member biases the latch carriers toward the longitudinal axis.  The locking latch has a first portion which, in the "on" position of the switching slide, engages the detent recess in the free end of the detent bolt to retain the detent bolt within the door lock housing, and has a second portion which, in the "off" position of the switching slide, engages the stub end of the switching slide to retain the switching slide against longitudinal movement toward the "on" position.

Title: Transmission output assembly
Inventor: JOYNER ROBERT G
IPC: F16H57/02
Filed: 1990-07-25
Abstract: ABSTRACT OF THE DISCLOSURE    An output assembly for a transmission range box connected to a vehicle drive shaft is disclosed.  The output assembly includes a hollow cylindrical output tube, having internal splines formed on the inner surface thereof, and a yoke shaft, having a solid cylindrical shaft portion with external splines formed on the outer surface thereof.  The yoke shaft is connected to the output tube by inserting the male splined shaft portion within the female splined tube.  Thus, the yoke shaft rotates with the output tube, while being axially movable relative thereto.  Such axial movement is designed to accommodate variations in the physical distance between the range box 10 and the next component of the drive train of the vehicle, such as differential, without having to provide a slip yoke structure on the drive shaft connected to the yoke shaft. A seal may be provided to engage the outer surface of either the output tube or the end yoke.
Patent CA-2023426-A1 (CA)
IPC: H04N1/00
Filed: 1990-08-16
Abstract: ABSTRACT OF THE DISCLOSURE    The analog signals from the reading means and the plural number of detecting means provided in the facsimile communication apparatus of the invention are selected sequentially by the selective connecting means for connection to the analog/digital conversion means and converted into digital signals.  This eliminates the necessity of connecting individual analog/digital conversion means to the reading means and the plural number of detecting means and enables miniaturization of the apparatus construction by reducing the number of parts used.          Moreover, the miniaturization of the construction can be further promoted because of the fact that the parts reduced are the parts for processing analog signals.

Abstract: RADIO CHANNEL ALLOCATION BASED ON       LOCATION OF MOBILE USERS          ABSTRACT     A broadcast two-way radio communication system has a plurality of transmit/receive stations which function as repeaters.  Each of the stations has a corresponding geographically defined operation zone.  A mobile radio transmits a request for use of a communication channel. Along with this request, the mobile radio provides its geographic location, which is derived from equipment located in conjunction with the mobile radio.  Upon receipt of the channel request and geographic location for a mobile radio, the control computer system determines the requesting mobile radio is a member of a zone restricted user group.  If so, the mobile radio is allocated a channel, if available, in the restricted zone of the mobile radio.  Should no channel be available at the restricted zone, the system attempts to allocate a channel from a station which has radio propagation overlap that extends into the restricted zone.  If, however, the mobile radio is located outside the zone of the requesting mobile radio, the request is ignored.  By allocating channels to restricted mobile radios only in the restricted or adjacent zones there are fewer channels allocated for the request, thereby eliminating excess channel allocations and utilization of interconnecting network trunks.

Abstract: ABSTRACT    A ball  valve  device  for  controlling  fluid  flow has  a stainless steel ball positioned in the lumen of an I.V. tube.          The outer diameter of the ball is equal to the inner diameter of  the  I.V.  tube,  so  that  the  outer  surface  of  the  ball establishes a fluid seal with the inner surface of the tube.  A latex sheath surrounds the tube in the proximity of the ball to provide  resilience  and  memory  for  the  tube.    Inserts  are positioned in the lumen both upstream and downstream from the ball  to hold  the ball  in position under the sheath.   Each insert is formed with a lumen for fluid flow, and has a tapered surface adjacent  to the  ball,  which prevents the ball from forming a seal with the insert.

Abstract: ABSTRACT        Therefore, in the case of the robot according to the present invention, the moment M generated about the horizontal pivotal axis at the lower end of the lower arm 6 due to the load W applied to the upper end of the upper arm 11 is not subjected to the influence of the length ?2 and the pivotal angle of the upper arm 11, as indicated by the above formula (4).  In other words, the moment of the upper arm 11 is not transmitted to the lower arms 6 and  7  as  moment  to  pivot  these  lower  arms,  but transmitted to the lower ends of these lower arms 6 and 7 as gravity load.   It should be noted that the above-mentioned  feature  is  not  obtained  in  the  prior-art vertical multijoint robot (as shown in Fig. 2), because the horizontal distance between the load action point of the upper arm and the pivotal axis of the driving portion at the lower end of the lower arm becomes an arm (or lever) length of moment generated about the pivotal axis of the base in relation to the lengths of the upper and lower arms.   In the present invention, however, since a parallelogrammic  link  mechanism  is  adopted,  it  is possible to provide the above-mentioned effect for the robot.  therefore, the driving motor power can be reduced markedly and therefore the robot is suitable for use as industrial heavy load robots, in particular.

Title: Collision sensor
Inventor: GRAY FLOYD L
IPC: A61B6/10
Filed: 1991-04-04
Abstract: A collision sensor specially adapted for a power driven x-ray imaging apparatus includes a face collision sensor and an edge collision sensor. The face collision sensor has two annular plates which are biased apart longitudinally by three flat springs which are equiangularly spaced apart around the perimeter of the plates. Three equiangularly spaced cables hold the plates in parallel planes with the springs prestressed and collapse to allow the plates to be compressed together. Two sets of three switches each reside at equal angular intervals between the plates, with at least one of the switches of the first set being actuated when any point across the face of the sensor has been moved a predetermined longitudinal distance. At least one of the switches of the second set is actuated when the point on the face of the sensor has been moved a further predetermined longitudinal distance. An edge collision sensor includes a closed air bladder which surrounds the face collision sensor and in which a vacuum is drawn. A collision occurring around the edge of the face collision sensor causes an increase in the pressure of the bladder. A first pressure sensor is actuated if the pressure increase exceeds a first predetermined amount.  A second pressure sensor is actuated if an additional predetermined increase in pressure occurs.

Abstract: A process for forming the ridge structure of a self-aligned semiconductor laser, particularly useful for long wavelength devices as required for signal transmission systems.   Described is the process as applied to an InP-system, double heterostructure (DH) laser. A thin Si3N4 layer (41) is inserted between the photoresist mask (42) that defines the ridge structure, and the contact layer (35). This results in improved adhesion and reduced etch undercutting whereby the ohmic contact area is increased, heat development decreased and device properties improved. Using a Si3N4 layer (41) deposited at a high plasma excitation frequency (RF) for adhesion promotion, and a low frequency deposited (LF) Si3N4 layer (43) for device embedding, provides for the etch selectivity required in the process stepthat is used to expose the contact layer to ohmic contact metallization deposition.

Abstract: The process for low-emission drying of a substance in a drum-type drying installation is suitable in particular for sewage sludge, fish meal and sludges from starch factories, soap factories and paper mills, which substances are preferably to be converted into granules.  The process is likewise very suitable for drying biomass products such as wood chips, grass, sugar beet chips and the like, since the emissions are very greatly reduced by means of this process.          The drying process is carried out in such a way that no unpleasant odours and dusts are emitted to the outside, because the actual drying circulation is closed.  Fossil fuels are used as the heat source for the burner for heating this air stream.

Title: Overvoltage protector assembly
Inventor: COSLEY MICHAEL R
IPC: H01R9/16
Filed: 1991-06-19
Abstract: An overvoltage protector assembly and a method of attaching a terminal member through a dielectric body. The assembly has a dielectric body, and line terminal members extending through the body into a chamber within. The terminal members each have a shaft passing through the body and first and second radially extending, opposing abutment-surfaces which engage inner and outer surfaces of the body.      The body is compressed between the opposing abutment surfaces in an axial direction of the shaft to deform the body inwards to sealingly engage the terminal member between the opposing abutment surfaces. The body is formed with axial projections around apertures receiving the line terminals. so that compressing the body results in displacement of. material of the body to form annular projections sealingly engaging around the shaft between the abutment surfaces.      Peripheral surfaces of the terminal member are cooperable with the body to prevent relative rotation of the body and the terminal member. The line terminal members are connected to a grounding terminal within the chamber via an overvoltage protection device.
