Abstract: The invention provides a method of introducing a 3'-terminal loop structure onto a target sequence of one strand of double stranded DNA, said target sequence having a region A at the 3'-terminus thereof and there being optionally a DNA region B which extends 3' from region A, whereby said double-stranded DNA is subjected to polymerase chain reaction (PCR) amplification using a first primer hybridising to the 3'-terminus of the sequence complementary to the target sequence, which first primer is immobilised or provided with means for attachement to a solid support, and a second primer having a 3'-terminal sequence which hybridises to at least a portion of A and/or B of the target sequence while having at its 5'-end a sequence substantially identical to A, said amplification producing double-stranded target DNA having at the 3'-end of the target sequence, in the following order, the region A, a region capable of forming a loop and a sequence A' complementary to sequence A, whereafter the amplified double-stranded DNA is subjected in immobilised form to strand separation whereby the non-immobilised target strand is liberated and region A' is permitted or caused to hybridise to region A, thereby forming said loop.
Patent CA-2137504-A1 (CA)
Inventor: LEE YOUNG W
IPC: G06F12/14
Filed: 1994-12-07
Abstract: The memory security circuit detects when a memory unit has been accessed independently of an address instruction of a programmable microprocessor. The microprocessor is programmed to provide a unique address signal for write enabling a discrete memory unit. The memory unit has a write enable pin and chip select pin which when enabled in combination permits writing into the memory unit. The address decoder receives the unique address instruction and causes a write enable signal and a chip select signal to be generated for that memory unit. The write enable signal and chip select signal are to be received, respectively, by the write enable pin and the chip select pin of the memory unit. The memory security circuit monitors the write enable pin and the chip select pin of the memory unit and generates a first output signal when the memory unit has been properly addressed. A second output signal is generated when the memory unit has not been addressed by the address decoder and the write enable and the chip select signals are present at the memory unit.

Title: Ultrasonic pulse-echo system and method
Inventor: ZWART JOHAN
IPC: G01N29/22
Filed: 1994-12-19
Abstract: An ultrasonic pulse-echo system has a transducer for transmitting and receiving pulsed ultrasonic signals along a first transmission path and a multiple reflection system.  The first transmission path is essentially parallel to a pipe wall to be examined.  The multiple reflection system comprises a first reflection plane and a second reflection plane.          The reflection planes define further transmission paths along which the beam originating from the transducer are projected onto the pipe wall at an angle, which in each case is greater than the critical angle of incidence so that the beam partly displaces further into the pipe wall.  The two transmission paths are such that the two beams coincide in the region of the pipe wall.  Reflections at the inner pipe wall surface from the path go back to the transducer by path and vice versa.  The same applies for reflection at the outer wall surface, but not for reflections from cracks or flows.

Title: Method and apparatus for treating an ophthalmic lens mold
Inventor: ADAMS JONATHAN P
IPC: B29L11/00
Filed: 1995-04-06
Abstract: An apparatus and method for causing the polymerized excess monomer to separate from a molded lens by increasing the surface energy of the flange area of one mold piece, causing the polymerized excess monomer to stick thereto. Specifically when manufactured under inert atmosphere conditions, a particular manifold is needed to supply an oxygen bearing gas, air, to the area to be treated while preventing the oxygen from contaminating the lens manufacturing area of the molds or diluting the nitrogen atmosphere of other lens process areas. It has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

Title: Process for the polynitration of aromatic compounds
Inventor: PIRKL HANS-GEORG
IPC: C07C205/06
Filed: 1995-10-13
Abstract: An aromatic compound is polynitrated in a continuous process in a single apparatus under adiabatic conditions in an emulsion as the reaction medium. From 1.3 to 3.5 mol of HNO3 per mol of aromatic compound are introduced in the form of a nitronium ion solution into the reactor with the aromatic compound under conditions such that an emulsion forms. The emulsion, which has a tendency to coalesce, is maintained by repeated dispersion. The first dispersion of the liquid streams to produce the emulsion takes place in less than one second. At least 20% of the total amount of HNO3 to be used should generally be present during this first dispersion. It is preferred, however, that the total amount of nitronium ion solution to be used be present at the time the aromatic compound and nitronium ion solution are first dispersed.

Abstract: An improved vacuum arc coating apparatus is provided, having a tube defining reaction zone with a plasma channel defined within a series of aligned annular substrate holders, or between an outer wall of an axial chain of substrate holder blocks and the inner wall of the tube. The substrate holders thus act as a liner, confining an arc within the plasma channel. Carrier and plasma-creating gases and the reaction species are introduced into the tube, and the deposition process may be carried out at a pressure between 10 Torr and 1000 Torr. Magnetic coils may be used to create a longitudinal magnetic field which focuses the plasma column created by the arc, and to create a transverse magnetic field which is used to bias the plasma column toward the substrates. Substrates can thus be placed anywhere within the reaction zone, and the transverse magnetic field can be used to direct the plasma column toward the substrate, or the tube itself can be rotated to pass the substrate through the plasma column.      In multiple-arc embodiments a plurality of substrate holders defining a plurality of arc channels may be aligned coaxially or distributed transversely about the reaction zone.

Inventor: JANGI SHRIRANG
IPC: H04Q1/46
Filed: 1996-03-11
Abstract: The present invention relates to an apparatus and method for sending and receiving digital signals in a voice communication system (10). The apparatus includes a first subscriber analog telephone (12), a transmitter (13), a receiver (19) including a tone generator (20), and a second subscriber analog telephone (23). The transmitter (13) includes a tone detector (14), a first antenna (16), and a second antenna (18). In the preferred embodiment, the first subscriber analog telephone (12) is connected to the transmitter (13), and the second subscriber analog telephone (23) is connected to the receiver (19). The transmitter (13) receives an analog signal (11) carrying speech and DTMF signals from the first subscriber telephone (12). The transmitting unit (13) converts the analog speechsignal into a digital speech signal. The tone detector (14) determines whether the digital speech signal contains any digit information, preferably dialed digits such as dual tone multifrequency (DTMF) tones, and encodes any detected digits into special tone packets. The transmitting unit (13) compresses the digital speech signal, replaces compressed speech packets with any special tone packets from the tone detector (14) if necessary, and transmits a digitally modulated and compressed output signal using the antenna (16) via an RF transmission channel. The digitally compressed signal is received by the receiver (19) using the second antenna (18). The tone generator (20) recovers any special tone packets in the received signal and generates a corresponding tone signal to be sent to the second telephone subscriber (23). The receiver (19) decompresses the digital speech signal and converts the signal to an analog speech signal (22) that is sent to the second subscriber telephone (23).
