Abstract: A miniature and high performance antenna applicable to a radio communication apparatus and made up of a straight antenna rod and an antenna coil or coil element. A first whip antenna has a first portion retractable into the casing of the apparatus and a second portion constantly positioned externally of the casing. A second whip antenna has a coil element in the form of a loading coil having a predetermined number of turns. The second whip antenna is coaxially provided on the upper end of the first whip antenna and slidable relative to and in the axial direction of the first whip antenna. The second portion of the first whip antenna is movable between a position where one end of the coil element is disengaged from one end of the second portion and a position where the former is engaged with the latter. The antenna exhibits a desirable electric characteristic when pulled out of the casing of the apparatus and, in addition, promotes the efficient use of the limited space available in the casing.

Title: Hydraulic oil well pump drive system
Inventor: STANLEY LLOYD
IPC: F04B53/00
Filed: 1993-03-01
Granted: 2004-05-25
Abstract: A hydraulic oil well pump drive system (100) for driving an oil well sucker rod (not shown) includes. a master piston (158) positioned within a master cylinder (156) for axial displacement between first and second ends of the master cylinder (156).    The master piston (158) has a piston drive rock (164) which extends through one end of the master cylinder (156). The drive rod (164) is connected to a crankpin (147) of an eccentric crank (144). The eccentric crank (144) is driven at a constant rotational speed to reciprocate the master piston (158) within the master cylinder (156) at a sinusoidal rate. A center seal assembly (168) divides the master cylinder (156) into a working chamber (170) and a pressure chamber (172) in opposite ends of the master cylinder (156). Each respective chamber defines a fluid volume which varies with the displacement of the master piston (158). The master piston (158) displacement creates a bi-directional flow of working fluid from the working chamber (170). A wellhead hydraulic assembly (111) is operably connected to the oil well sucker rod and is in fluid communication with the roaster cylinder working chamber (170) to receive the working fluid flow. The wellhead hydraulic assembly (111) is responsive to the working fluid flow to reciprocate an oil well sucker rod at a rate which relates to the rate of master piston (158) displacement. A gas accumulator (176) is in fluid communication with the master cylinder pressure chamber (172) to bias the master piston (158) toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly (111).

Title: Impact-type anchor
Inventor: MADER EBERHARD
IPC: F16B13/12
Filed: 1996-08-02
Granted: 2002-02-05
Abstract: An impact-type anchor (1) is proposed that consists of a metal sleeve (2) having an internal thread (4) for screwing in a screw and a through bore (3) that tapers towards the leading end, into which bore an expander body (5) can be driven to expand the impact-type anchor.            For the inexpensive manufacture of the metal sleeve combined with pull-out values that are the same as those of a metal sleeve made of solid material, the metal sleeve is stamped out of a sheet metal blank and then rolled up to form a sleeve joined at its seam. Further-more, in order to form the tapering internal bore the expansible legs (7) have a first section (7a) that is bent inwards, onto the outer face of which first section there is bent round a second section (7b). The two sections (7a, 7b) that rest one against the other are connected non-displaceably to one another, for example, by means of a punched point (9). (Figure 1).

Title: Skin testing and vaccinating needles and method of use thereof
Inventor: HEIN GARY L
IPC: A61B17/20
Filed: 1995-02-21
Granted: 2005-04-19
Abstract: This invention is a plastic skin testing and vaccinating needle (5) characterized by an end bifurcated into two sharp points (6) spaced sufficiently close so that in use the points (6) will penetrate and form a small hole in the skin when the needle (5) is simultaneously rotated and pressed against the skin.  The spacing also causes liquid to adhere to and between the points (6) when the end is dipped in skin testing or vaccinating liquid.  The cross section of the needle shaft in sufficiently large that the needle (5) can be readily rotated between a user's thumb and index finger.  Rotation is facilitated by altering or roughening the surface of the shaft so as to reduce slippage during rotation.  Preferably, the needle (5) is formed in a mold produced by electro-discharge machining so as to have an etched or matte surface which enhances the adherence of liquid to the bifurcated end.

Patent CA-2200925-C (CA)
Inventor: CUNNINGHAM JOHN EDWARD
IPC: H01S3/098
Filed: 1997-03-25
Granted: 2000-08-01
Abstract: Low optical loss and simplified fabrication are achieved by a nonlinear reflector which incorporates one or more semiconductor quantum wells within an n half-wavelengths strain relief layer (where n is an odd integer greater than zero) that is formed on a standard semiconductor quarter wave stack reflector. Growth of the half-wavelength layer is controlled so that dislocations are formed in sufficient concentration at the interface region to act effectively as non-radiative recombination sources. After saturation, these recombination sources remove carrier, in the quantum well before the next round trip of the optical pulse arrives in the laser cavity. The nonlinear reflector is suitable for laser modelocking at the high wavelengths associated with many currently contemplated telecommunications applications and provides, at such wavelengths, an intensity dependent response that permits it to be used for saturable absorption directly in a main oscillating cavity of a laser. Saturation intensity of the nonlinear reflector and thereby related laser modelocking properties can be controlled by disposing the quantum well(s) at a particular position within the strain relief layer.

Abstract: De la vapeur (de préférence de la vapeur propre), renfermant moins de gaz non condensables que la vapeur obtenue par un système conventionnel d'évaporation instantanée de liqueur noire, est produite à partir de liqueur noire chaude provenant d'un lessiveur d'une fabrique de pâte à papier. Pour cela, on utilise un échangeur thermique (19) dans lequel on fait passer la liqueur noire chaude pour que celle-ci soit en contact thermique avec un liquide évaporable (18), de préférence de l'eau propre. Après réchauffement de l'eau dans l'échangeur thermique, celle-ci est évaporée instantanément dans au moins un réservoir de détente (21, 22), cet échangeur étant un échangeur thermique liquide-liquide qui peut, dans une autre variante, comporter un évaporateur (27) (tel qu'un évaporateur à ruissellement). Dans ce cas, la liqueur noire passe dans un inducteur (26) avant de pénétrer dans l'évaporateur. Ou bien, l'échangeur peut comporter une ou plusieurs chaudières, telles que des chaudières à bouilleurs, auquel cas la liqueur noire passe d'abord de préférence dans un refroidisseur (44), puis dans les chaudières. La récupération d'énergie thermique et de térébenthine est ainsi maximisée.
