Patent CA-1180788-A (CA)

Abstract: A b s t r a c t A system for registrating an article passing a prede-termined area, and comprising a transmitter and a receiver with a common aerial alternately transmitting and receiving electromagnetic signals. A marker is attached to each article and receives said signals and transmits in turn other signals at passage of the area. The common transmitting and receiving aerial is formed as a multipole loop, preferably looped as a figure-of-eight dipole loop located in one plane. The known systems are encumbered with the problem that the marker with some orientations can pass without being detected.  According to the invention the transmitting period is followed by a first receiving period in which the number of wave peaks is counted, and at least one additional receiving period in which the number of peaks is counted too. If the number of peaks during the first receiving period is suffi-ciently high, and the following period does not include too many peaks, the presence of a marker in the area is indicated.          This system is so sensitive that the weaker side areas of another orientation than the main area may be utilized too.          As a result, the marker cannot pass the area without being detected irrespective of its orientation.

Abstract: ABSTRACT   An electronic theft detection apparatus for detection of saturable magnetic targets has transmitter and receiver antennas formed of single turn loops of rigid metal pipe.  The antennas are rectangular and have a width, in the direction of passage, through the interrogation zone, less than the length of a shopping cart.  The transmitter antenna is in the form of a rectangular loop and the receiver antenna is of the same overall size and configura-tion but is bisected with a conductor to form two balanced loops.  The antennas are purely inductive and a series resonant circuit is inductively coupled into the transmitter antenna and a parallel resonant circuit is inductively coupled out of the receiver antenna.  Special circuits are also provided for temporarily disabling the apparatus when a related lower harmonic frequency signal decreases in amplitude.

Abstract: APPARATUS AND METHOD FOR ROUGH POSITIONING          A VEHICLE AT A STORAGE BIN IN AN AUTOMATIC               STORAGE AND RETRIEVAL SYSTEM                 Abstract An automatic storage and retrieval system including a storage bin, having a mechanism for positioning a vehicle at the storage bin including a rough positioning mechanism with an encoder having a rotatable member which rotates through an arc less than a complete revolution in response to movement of the vehicle and generates a signal with a different value at each of various member positions which correspond to respective vehicle rough position zones.  A control device receives the signal and selectively causes the vehicle to move to a rough position zone at the storage bin.  A fine positioning mechanism repositions the vehicle within a particular position zone after rough positioning and utilizes a light source and photoelectric sensor mounted on the vehicle for detecting a target mounted in a fixed relation with respect to the storage bin.  The control mechanism receives an electrical signal generated by the photoelectric sensor and causes the vehicle to stop at the fine position location at the storage bin.  A high-low positioning device selectively lowers and raises a carriage including a retrieval apparatus such as a fork assembly within the bin.  A method is provided to utilize the automatic storage and retrieval system including rough and fine positioning of a vehicle relative to a storage bin and high-low positioning within the bin.

Abstract: Abstract of the Disclosure An apparatus for mounting relatively small and deformable elongated rails on a relatively large, generally horizontal, and nondeformable elongated rail beam has a stiff but limitedly elastically deformable elongated jig.  A plurality of clamps spaced longitudinally along the jig are engageable with the rail for locking onto the rail at respective longitudinally spaced locations.  Respective vertical and horizontal jacks transversely engage between the clamps and the jig for elastically deforming the jig into a desired shape relative to the rail beam.  Holders and the lke are provided on the jig for securing the deformable rails to the rail beam in predetermined positions relative to the deformed jig.  If the rail section is to be curved in any direction the jig is appropriately deformed relative to the rail beam so its various holders and mounting fixtures lie on the appropriate curve. Such elastic deformation of the jig therefore perfectly positions these rail holders.  The clamps include respective horizontal and transverse clamp beams at the locations, respective jaws on the beams, and respective hydraulic actuators for locking the jaws on the rail beam at the respective locations and thereby solidly arresting the transverse beams on the rail beam at the respective locations.

Abstract: ABSTRACT OF THE DISCLOSURE             A process and electroplating bath for use in electro-depositing nickel on a base where the electroplating bath includes a coumarin compound and an aryl hydroxy carboxylic acid compound, such as salicylic  acid, present in a combined amount effective to provide a ductile, self-leveling nickel deposit.   The bath may further include hexyne diol and/or a material selected from the group consisting of primary acetylenic alcohols and adducts of primary acetylenic alcohols, as well as mixtures thereof.  It has been found that excellent leveling and physical properties can be maintained utilizing such a bath, while at the same time, the usual coumarin concentration level can be reduced significantly and process life can be dramatically extended.   In addition, additives such as butyne diol, and/or aldehydes such as formaldehyde and chloral hydrate may be utilized.   It has also been found that corrosion resistance is substantially improved utilizing the process and electroplating bath of the present invention.
