Title: Portable combination cooking grill
Inventor: PURELLO ALFRED C
IPC: A47J37/06
Filed: 1990-02-20
Abstract: Abstract of the Disclosure A cooking grill designed to overlie a conventional outdoor barbecue is disclosed having a portable, unitary cooking surface that includes both a griddle section and a charbroil section to allow for the simultaneous and efficient frying and charbroiling or food over the barbecue.  Preferably, depending arms are attached to the underside of the unitary cooking surface and are spaced to support the surface when removed from the barbecue such that the surface may be used to serve cooked food.  The downwardly depending arms are also located and sized to prevent lateral movement of the cooking surface relative to the conventional barbecue when the surface overlies the barbecue.  Additional features of the portable grill include an upwardly extending circumferential lip about each of the griddle section and the charbroil section to facilitate the retention of food on the cooking surface and a unique detachably connectable handle means for moving the cooking surface.

Patent CA-2015038-A1 (CA)
Inventor: PALLMANN WILHELM
IPC: B23Q7/06
Filed: 1990-04-20
Abstract: ABSTRACT OF THE DISCLOSURE     A device suitable for the continuous feeding of wood pieces of approximately the same length into flaking machines comprises a feed trough opening into the flaking machine, behind which there is arranged a loading magazine whose cross section agrees with the feed trough. The lengths of wood are shaped into compact piles, which are then advanced cyclically into the flaking machine by means of a pushing plate.  In order to be able to bring the pushing plate back over the log pile already prepared for further processing inside the loading magazine, the pushing plate is able to be slewed upon a support that can be moved parallel to the floor of the device, over both the feed trough and the loading magazine. Control members attached to the pushing plate interact for short intervals with stationary control paths at the beginning and end of the return trip of the pushing plate to cause the plate to tip either into its withdrawal position or into its pushing position.  Additionally, a sliding closer, which can be slid between the feed trough and the flaking machine, serves, during the last flaking cycle, to close the flaking chamber, and, during the preceding flaking cycles, to exert additional pressure on the log pile to be processed.

Title: Depilatory device
Inventor: CHERMONI ISRAEL
IPC: A45D26/00
Filed: 1990-07-13
Abstract: ABSTRACT           A depilatory device is provided comprising a housing having a first rotary element mounted with respect to the housing for free rotational movement about an axis.  A second rotary element is also mounted with respect to the housing so as to be rotatable about the axis.  A drive motor mounted in the housing is coupled to the second element and is operable to rotate the second element about the axis and axially displace it with respect to the first element so that the circular end surfaces of the rotary elements move towards and away from each other.  The arrangement of the end surfaces is such that hairs interposed between the surfaces are gripped thereby when the surfaces come closer together and are plucked upon continued rotation of the elements during the period of closest approach of the end surfaces.

Title: Method of measuring oxygen activities in slag, apparatus therefor and disposable crucible used therefor
Inventor: IWASE MASANORI
IPC: G01N33/20
Filed: 1990-10-15
Abstract: ABSTRACT    A method and apparatus for measuring the oxygen activi-ty of the slag in molten iron or molten steel with high accuracy.  A conventional measuring method in which an oxygen concentration cell produced by winding a platinum contact electrode around the outer surface of a solid electrolyte of one end closed tube type is disposed directly in the molten slag involves a fear of producing an error in measurement due to the difficulty in positioning in the fluid slag and the defective contact with the contact electrode caused by the densification by the heat of the slag.  In the present invention, the oxygen activity in the slag is not directly measured but a specific metal between which and the slag an oxygen equilibrium is established when it comes into contact with the slag is charged in a container together with the slag.  The oxygen activity of the specific metal is measured so as to indirectly measure the oxygen activity in the slag.  The problems caused by the defective contact between the solid electrolyte and the contact electrolyte are thus solved, thereby enabling measurement of the oxygen activity in the slag with high accuracy.

IPC: F16D69/02
Filed: 1991-07-10
Abstract: A novel friction pad is disclosed for use with a motor vehicle window stabilizer of the type having at least one face which frictionally engages a window pane as it moves between its raised and its lowered position. The friction pad is constructed from an elastomeric substrate having a planar base and a plurality of spaced apart projections extending outwardly from one side of the base. The projections and the base are of a one piece construction. A coating of synthetic material, such as nylon or polyester, is then flocked onto the side of the base thus covering both that side of the base as well as the projections. The resulting friction pad is then secured to the confronting face of the window stabilizer.

Title: Jettisonable mine
Inventor: PAECH JOACHIM
IPC: F42B23/00
Filed: 1991-08-28
Abstract: ABSTRACT     In the case of known jettisonable mines, in the normal course of events, because of ground characteristics and in the slope in the ground it is necessary to erect the mine into a position that enables it to work with maximum effect, in which the mine should be fixable for its total service life, regardless of external influences.     Since such fixing has up to now been costly and unsatisfactory, in a mine (10) according to the present invention, there is a bag (18) arranged beneath an air bag (16), said bag being filled with a hardenable plastic foam.  In this way, the stability of the mine (10) is greatly improved.  Because of a permeable underside (22) of the bag (18), the foam can also escape into a zone (34) between the ground (12) and the bag (18) and cement the mine (10) into its position on the ground (12).

Abstract: A hybrid matrix amplifier system that yields balanced thermal loads with minimal input signal constraints includes an input multiport hybrid coupler system having outputs joined to a plurality of amplifiers, and an output multiport hybrid coupler system joined to the outputs of the amplifiers. The input multiport hybrid coupler system, and the output multiport hybrid coupler system, each include n stages where n is an integer equal to or greater than 1, with each stage including 2n-1 couplers. These coupler systems may also include strategically-placed phase shifters. Such systems also include N amplifiers where N is equal to 2n, with N inputs from the outputs of the input multiport hybrid coupler system, and with the outputs of the amplifiers connected as inputs to the output multiport hybrid coupler system. This configuration permits a division of the N amplifiers into two groups that each dissipates substantially the same quantity of heat energy.

Title: Transformed shigella
Inventor: SANSONETTI PHILIPPE
IPC: A61P31/04
Filed: 1991-02-05
Abstract: A method for modifying a wild strain of an entero-invasive Shigella to produce a modified strain of Shigella that can be used for making a vaccine against the wild strain. The genome of the wild strain is transformed by deleting all or a substantial part of: a) both its ompR and envZ genes; or b) its ompF gene. This renders the strain substantially less invasive. One or more additional genes of the wild strain, such as the icsA gene, are also deleted in whole or in part so that the so-modified strain is sufficiently non-invasive to be safe for use in a vaccine but sufficiently active to provide protection against the wild strain.
