Title: Edging block
Inventor: BENDER DAVID C
IPC: E01C11/22
Filed: 1993-04-28
Abstract: A B S T R A C T         A cast concrete landscape or paving edging block which comprises a top surface, a bottom surface, a pair of side surfaces, a convexly curved end surface and a concavely curved end surface, wherein said end surfaces are provided with alternating ridges and grooves extending between the top and bottom surfaces.          Such end surfaces are complementary, whereby the convexly curved end surface of a block is adapted to nest within the concavely curved end surface of a like block with the ridges of one end surface nesting within the grooves of the complementary end surface.  In this manner, the adjacent edging blocks resist both relative transverse displacement and relative angular displacement by reason of the nesting convex/concave end surfaces, and against relative angular displacement by reason of the nesting ridges and grooves.

Title: Writing device
Inventor: GORBUNOV ALEXEI E
IPC: B43K23/012
Filed: 1992-09-21
Abstract: A writing device which allows to eliminate the "writing spasm", to increase the writing speed and to decrease fatigue during a long period of work of a writing person. The device allows to facilitate the handwriting process of arthritis patients, invalids with missing fingers, students, computer users, journalists, children. The device is characterized in that a ring (3) is the continuation of a casing (1) and is made as one part together with the latter, the opening of the ring (3) has elliptic form, whereas the casing (1) and the ring (3) are so mutually oriented that the direct line connecting the point of the writing element (2) with the closest point of the ellipse crosses the large axis of the ellipse at the said point. This allows to eliminate the static stress of the fingers holding the pen due to the transfer of the point of support during the writing process to the point of connection of the index finger phalanx with the hand at the palm side. The device may be provided with a counterbalance (7) mounted at the ring (3) at the side opposite to the writing element (2). The centre of gravity is located at the support point of the device.

Patent CA-2105681-A1 (CA)
Title: Low noise optical probe
Inventor: DIAB MOHAMED K
IPC: H05K1/18
Filed: 1992-03-05
Abstract: An optical probe (100) which is particularly suited to reduce noise in measruements taken on an easily compressible mate-rial, such as a finger, a toe, a forehead, an earlobe, or a lip. The probe includes a base (110) having an aperture (120) which leads to a chamber (122). The base is placed adjacent a portion of the material, the chamber being placed directly adjacent any easily compressible portion of the material. A photodetector (126) is located within the chamber and does not contact the material. A light emitting diode (LED) (130) is affixed to the material, opposite the photodetector and above the chamber. The material which is supported by the aperture and therefore rests above or has intruded into the chamber is inhibited from compression since no-thing comes in contact with this portion of the material, even when the material moves. Thus, light from the LED is directed through a stabilized portion of the material, such that the optical path length through which light travels is stabilized.

Title: High-density storage rack system for magnetic data storage tape cartridges
Inventor: PRICE MACY J JR
IPC: B65D85/575
Filed: 1992-04-03
Abstract: A high-density storage system including an upstanding rack (10) having a plurality of vertical support members (20). Vertically aligned ap-ertures (36) are formed in each support member and on both sides of the support members. An elongated dimple (38) is formed adjacent each of the apertures. The cartridges are stored in cartridge storage packs (40) which are designed to be mounted onto the rack. The cartridge storage packs include resilient suspension hooks (64) formed on the rear surface of each cartridge storage pack. The suspension hooks (64) are inserted in-to the apertures to support the cartridge storage packs on the rack. The suspension hooks include a resilient arm (66) which biases against the el-ongated dimple (38) to prevent accidental dislodgement of the cartridge storage packs (40). The apertures (36) are arranged so that the cartridge storage packs (40) are mounted in close proximity with one another. This increases the density of the cartridge storage capacity of the system to al-low more cartridges to be stored within existing space,
Patent CA-2108096-A1 (CA)
Inventor: GOOSSEN KEITH W
IPC: H01L31/0216
Filed: 1993-10-08
Abstract: A  tunable  monolithic  integrated  photodetector  (10) detects a selected wavelength of incident light within a wavelength range.   The photodetector comprises a multiple quantum well (MQW) filter means for receiving and filtering the incident light, and an MQW detector means for receiving light from the MQW filter means and for detecting the selected wavelength.  A fixed voltage bias V.DELTA. is disposed between the filter means and the detector means for causing the filter means  to  absorb  light  wavelengths  around  the  selected wavelength  to  thereby  enhance  the  detectability  of  the selected wavelength.  Further, a variable voltage bias Vp is selectively and proportionally imposed on both the filter means and the detector means for permitting tuning of the photodetector.   A fixed filter may also be employed for filtering the incident light so that light wavelengths which are outside the range of the photodetector are eliminated. Finally, a plurality of the photodetectors may be arranged in a two dimensional array for image processing.

Abstract: A method and apparatus is described whereby a child or other person may learn to use two different notational systems for coins, such as cents and dollars, by following an ordered set of instructions that guide the matching of movable graphic symbols and coin-replicas onto identical graphics on a printed surface.  In the example the user learns 1) to recognize and name a notational symbol corresponding to each of the two notational systems; 2) that the two different systems can be used to express the same amount of money; 3) to associate the physical manipulation of a coin or coin-replica simultaneously with both notational systems; 4) to calculate and physically assemble the amount of coins or coin-replicas of a given denomination that sum to the unit value of the second notational system; and 5) to calculate and physically assemble the amount of coins or coin-replicas of a mixture of denominations that sum to a requested amount. Additionally, a final evaluation step provides feedback and options relative to calculating the requested amount.

Patent CA-2117586-A1 (CA)
Inventor: SAITO MASAKI
IPC: F23Q2/16
Filed: 1994-08-29
Abstract: A gas lighter with a safety device is provided with a resilient leaf which can be deformed between a locked state in which the depression of a pressing means is prevented and a lock-released state in which the operation of the pressing means is allowed, and a slide member which is fitted around the resilient leaf and is movable between a first position where ignition operation is impracticable when the resilient leaf is in a locked state and a second position where the ignition operation is practicable.  The slide member deforms the resilient leaf and renders it in a lock-released state at a third position which is reached during movement from the second position to the first position in response to ignition operation.  The gas lighter is also provided with a deformation suppressing means for reducing the amount of deformation of the resilient leaf obtained when the slide member is located at the second position so as to be less than the amount of deformation of the resilient leaf in a lock-released state when the slide member is located at the third position.
