Patent CA-2130453-A1 (CA)
Inventor: LE PAGE RICHARD W F
IPC: A01N63/50
Filed: 1993-03-01
Abstract: 2130453 9317117 PCTABS00025 Heterologous polypeptides are produced in Lactococcus by means of a T7 or T7-like RNA polymerase gene placed under the control of an inducible promoter effective in the Lactococcal host, and a promoter specific for said polymerase upstream of a coding sequence for the desired polypeptide, whereby the promoter directs transcription of said coding sequence selectively as a result of expression of said polymerase. Surprisingly, the Gram-negative E.  coli) derived T7 RNA polymerase system works extremely well in the Gram-positive Lactococcus host. The heterologous polypeptide can be produced in high yields (e.g. 22%) as soluble intracellular protein, or can be secreted, e.g. at a rate commensurate with its expression so that only low levels or zero amount of polypeptide is accumulated intracellularly. The polypeptide within the cell, being biologically active, can be delivered in that encapsulated form, e.g. as a parenteral, topical or oral medicament or vaccine, or as an environmental pesticide. Examples of expression product are TTFC, the HIV V3 loop and B. thuringiensis toxins.

Patent CA-2134689-A1 (CA)
Inventor: DUNCAN WAYNE C
IPC: B25B17/00
Filed: 1994-10-18
Abstract: A reversible gearless drive mechanism for a socket wrench comprises a driven member having an upper centering support flange and a lower centering support race, between which is a cam-like area around the circumference defining three symmetrically opposite bi-directional ramps.   The driven member is axially centered within a drive member defining a round cylindrical bore, between which each bi-directional ramp forms one right hand wedge and one left hand wedge.  Between  each  two  bi-directional  ramps  are two cylindrical rollers held apart into their respective left hand and right hand wedges by a leaf spring. The cammed circumference of the driven member does not contact the inner circumference of the bore for centering support permitting the use of larger diameter  rollers relative to the diameter of the bore in which the mechanism is centered. The larger diameter rollers combined with the pressure of the leaf springs provide adequate friction drag to hold the driven member stationary while a thumb operated rotary selector switch overcomes a spring and pin detente to unwedge either the three left hand or the three right hand rollers  to change the direction of drive.  This permits a change in drive directions with only one available hand. The larger diameter rollers also provide a more positive lock for the drive and are more tolerant to small particles and imperfections caused from wear or contamination.

Title: Vaccine for susceptible hosts against nonadapted parasites
Inventor: GRIEVE ROBERT B
IPC: C07K14/435
Filed: 1993-05-14
Abstract: It has been found that hosts which are susceptible to nematode parasite infections can readily be protected from such infections when the parasites are not adapted for a parasite/host relationship to this host. In particular, feline hosts were immunized against heartworm using a variety of antigens derived from Dirofilaria immitis and related nematodes. Because cats are hosts susceptible to this nonadapted parasite, such antigens are successfully protective.

Title: Method of providing sacrificial spacer for micro-mechanical devices
Inventor: BAKER JAMES C
IPC: H01L21/302
Filed: 1995-05-23
Abstract: A method of fabricating micro-mechanical devices that use support elements (13) raised from a substrate (15), to support moveable elements (11).  First, support elements (13) having reflective top surfaces (31) are fabricated. A layer of photoresist material (41) is then deposited over the  support  elements   (13),   to   a  thickness   that substantially covers their reflective top surfaces  (31). The photoresist layer (41) is exposed, which results in the areas (61) over the support elements (13) being more highly exposed than the areas (62) between the support elements (13).  This permits a subsequent developing step that can be controlled to the purpose of removing the photoresist between the support elements (13) to a height planar with the reflective top surfaces of the support elements, while guaranteeing that the photoresist will be removed over the support elements (13).

Patent CA-2155553-A1 (CA)
Inventor: STUART NICHOLAS FISHER
IPC: H04M1/72505
Filed: 1994-02-10
Abstract: A communications  system for establishing radio transmission and reception between one or more base units (1) and one or more portable units (2, 3). Upon reception at a base unit (1) of an incoming call a first callout signal is transmitted to one or more portable units (2, 3) by the base unit (1). This first callout signal does not contain any information   about operating a ringing device located in each portable unit (2, 3), however, when the sequence signal from the first portable unit (2, 3) to respond to the callout signal is received by the base unit (1) the base unit (1) sends out a second callout signal. This second callout signal contains information  which starts a ringing cadence off, at the beginning of the cadence, in the ringing device in the first portable unit (2, 3) to respond and thus there is always only a small delay between a base unit (1) and a portable unit (2, 3) making contact and the portable unit beginning to ring.
