Title: Electronic control system for explosives
Inventor: SCHULTZ RICHARD
IPC: F42D1/055
Filed: 1991-11-07
Abstract: A control system for detonating a plurality of blast explosives is programmable to receive and store an arming sequence and firing sequence which is compared with an operator entered command. The system generates both an ARM signal and a FIRE signal, wherein the ARM signal initiates a charge circuit (26) to charge up a detonation circuit (54) and the FIRE command releases the charge to fire the circuit. The firing sequence contains a programmable delay (66) making sequential blasting possi-ble. The system is designed to fail safely in the event both the ARM signal and the FIRE signal do not appear within a predeter-mined time frame.

Title: Pressing tool for pressing a cylindrical pressing member or a pressing member comprising a cylindrical portion onto a round profile, particularly a pipe conduit
Inventor: HOMM KARL G
IPC: B25B27/10
Filed: 1992-09-04
Abstract: ABSTRACT    Pressing tool for pressing a cylindrical pressing member or a pressing member comprising a cylindrical portion onto a round profile, particularly a pipe conduit The pressing tool  (10)  comprises two holding members (26,28) adapted to be moved towards each other and hav-ing press dies (44,46) displaceably arranged thereon. Adjacent press dies  (44,46)  are oriented at a right angle to each other, with two press dies  (44) being supported on one holding member (26) and two further press dies  (46) being supported on the other holding member (28). The press dies (44,46) of both  holding members (26,28) can be displaced along an axis extend-ing at an angle of about 45° to the moving direction of at least one of the two holding members (26,28). Prior to the pressing process,  the press dies  (44,46)  are spaced from each other,  and during the pressing pro-cess, while the holding members (26,28) approach each other, the press dies (44,46) move towards each other until reaching their final closing position. Due to the displaceability of the press dies (44,46) on the hold-ing members (26,28) and the fact that all of the press dies  (44,46)  are displaced by a rotational angle of about 45° with respect to the moving direction of the at  least  one  holding  member  (28),  the  press  dies (44,46) are centrically guided during the pressing pro-cess so that they move radially towards the pressing member (49) to be connected by pressing action.            (Fig. 2)

Patent CA-2081188-A1 (CA)
Title: Apparatus and method for continuous speech recognition
Inventor: HIRSH HANAVI M
IPC: B41J5/00
Filed: 1992-10-22
Abstract: Abstract In systems for recognizing continuous speech, this invention provides an improved method for dividing an utterance into word-length segments. In the many earlier attempts undertaken by others in this field, the critical step of utterance segmentation has been accomplished by trial-and-error approaches in which individual sounds must first be delimited, identified, and then concatenated into hypothesized words.  Because conventional processes are complex, computationally expensive, and error prone, with the computational burden quickly growing as the number of permitted words increases, real-time operation requires expensive high speed computers.  In contrast, my invention uses a simple and effective technique to directly segment the utterance.  Using a computer mouse, the operator indicates word breaks by sending signals which coincide in time with the boundaries of spoken words.  With the words thus delimited, the different segments of an utterance can be processed simultaneously via a low cost general purpose computer, using appropriate processing strateg-ies chosen according to segment length.  Unknown utterance segments are matched with templates of words stores in the specially prepared lexicon.  In addition to conventional acoustic parameters, prosodic ones are used to increase the precision and efficiency of the matching process.  Practical applications of this invention, such as voice-actuated typewriters, can be based on low-cost microcomputers.  Such devices will be welcomed by keyboard-shy managers, by the blind, and by the physically handicapped.  A voice-actuated typewriter can also facilitate communication with the hearing impaired.
