Title: Improvements to the manufacture of yarn spun on closed-end, high draft spinning systems
Inventor: LAPPAGE JAMES
IPC: D01H5/28
Filed: 1993-07-14
Abstract: Improvements to the manufacture of yarn spun on closed-end, high draft spinning systems, in which a yarn structure is formed in which each of the constituent fibres migrates between the surface and the core of the yarn so that part or parts of each fibre are trapped and bound by parts of other fibres in the yarn cross-section. The constituent fibres can migrate cyclically between the core and the surface of the yarn or the migration or withdrawal of individual fibres can be impeded by a degree of inter-fibre entanglement deliberately introduced in the yarn structure. Mechanisms for producing the yarn structure are also described.

Title: Cold induced promoter from winter brassica napus
Inventor: SINGH JAS
IPC: C07K14/415
Filed: 1995-04-10
Abstract: A 1.2 kb fragment of the 5' regulatory region (from bp -1107 to + 100) was fused to the GUS (.beta.-glucuronidase) reporter gene and BN115-promoted GUS expression was observed in green tissues of transgenic Brassica napus plants only after incubation at 2°C. No expression was observed after incubation at 22°C, either in the presence or absence of abscisic acid.    Microprojectile bombardment of winter B. napus leaves with a BN115 promoter/GUS construct yielded similar results and was used to analyze a series of deletions from the 5' end of the promoter. Results obtained from transient expression studies showed that the low temperature regulation of BN115 expression involves a possible enhancer region between bp -1107 and -606 and a second positive regulatory region located between bp -302 and -274. Deletion analyses and results from replacement with a truncated CaMV (cauliflower mosaic virus) 35S promoter suggest that the minimal size required for any maintenance of low temperature GUS expression is a -300 by fragment. Within this fragment are two 8 bp elements with the sequence TGGCCGAC, which are identical to those present in the positive regulatory region of the promoter of the homologous Arabidopsis cor15a gene and to a bp core sequence in the low temperature- and dehydration-responsive elements (LTREs and DREs) identified in the promoter regions of several cold-responsive Arabidopsis thaliana genes. Mutation of either one or both of the GGCAC core sequence of the putative LTRE's to AATTC resulted in loss of cold-inducible gene expression, providing for the first time, direct evidence that CCGAC is required for low temperature expression.      Furthermore, replacement of an enhancer region (-605 to -1107) of the promoter with a more active enhancer from the 35S constitutive cauliflower mosaic virus (CaMV) promoter resulted in a "hybrid" promoter with increased low temperature induced activity several fold over that of the native promoter.

Title: Mineral wool product, method for producing it, and glue foam therefor
Inventor: KUMMERMEHR HANS
IPC: B32B7/12
Filed: 1994-11-11
Abstract: Laminated mineral wool products which have to comply with high fire protection standards, such as building material belonging to Class A2 according to DIN 4102, require special production expenses if the laminating foil is to be reliably fastened with organic glue without downgrading its fire protection classification. By foaming the glue it is possible to manage with a fraction of the hitherto required quantity of glue without having to accept an essential lowering of glue performance. As a result, organic glue can be used without its fire load having to be neutralised by polluting flame-inhibiting agents. Furthermore the glue foam causes less problems during processing in production, reduces the charged quantity of glue, and reduces the required drying capacities. It is particularly suited for difficult applications such as laminating felt which is rolled for packaging or laminated panels comprising erect fibers.

Title: Dry powder inhaler with an inhalation-activated piston
Inventor: MULHAUSER PAUL
IPC: A61M13/00
Filed: 1994-05-06
Abstract: A dry powder inhalator (20) for delivering a precise dose of a medicament contains a mesh disc (10) impregnated with a series of spaced, medicament doses (16) about the disc periphery. The inhalator (20) is armed by manually retracting a finger-pull (54) extending downwardly from the bottom of the inhalator housing or rotating the bottom of the housing. The user inserts a mouthpiece (32) on the housing into the mouth and inhales. This causes a chamber (68) in the housing under a diaphragm (92) to evacuate, thereby pulling the diaphragm (92) down onto a knock out lever (96). The pivoting of the lever (96) enables release of a piston (62) into a cylinder (68) which first compresses, and then dispenses a reduced volume of air at high pressure in a burst up through the medicament disc (10). When the burst of air hits the impregnated disc (10), the dose (16) is forced out of the mesh's interstices, producing a cloud of the drug in its powdered form, which is inhaled by the user.

Filed: 1995-10-20
Abstract: A motor mounting plate system enables a motor to be mounted within a string trimmer without the need for a plurality of precisely formed ribs to support the motor within the housing. The motor mounting plate apparatus includes a planar mounting plate member and a U-shaped bracket member which are secured together to form a rigid motor mounting assembly.  The U-shaped bracket member is connected to the stator of the motor of the string trimmer.   A lower portion of the housing includes two housing halves, each including a groove formed therein.   The outer perimeter of the motor mounting plate is positioned in the groove of one of the housing halves during assembly to support the motor within the housing half without the need for the motor to rest on a rib or any other protruding portion of the interior of the housing.  The remaining housing half is then secured to the first mentioned housing half such that the motor mounting plate is secured substantially around its entire periphery within the groove formed in each housing half.  A bushing insert is included for achieving a tight interference fit between the smooth armature shaft of the motor and a plastic fan member. The motor mounting assembly also serves to absorb the force of the "bump" when the operator bumps the line spool of the trimmer against the ground to advance the cutting line.

Title: Vacuum insulated panel and method of making a vacuum insulated panel
Inventor: BRIDGES JOHN A
IPC: F17C13/00
Filed: 1994-04-28
Abstract: A vacuum insulated panel having high thermal insulating value and long vacuum life, and a method of making such a panel is disclosed. The panel is formed of peripherally welded metal wall members (212, 214) which define a cavity within which a compressed block (222b) of particulate material is disposed. The particulate material, preferably activated carbon, silica or a combination thereof, serves as a barrier to radiant thermal transmission through the panel, acts as a getter to maintain the vacuum in the cavity, and supports the walls of the panel against collapse when the cavity is evaluated. The vacuum insulated panel can be covered with a polyurethane foam insulating material. In one embodiment, the vacuum insulated panel can include a compressed cake of particulate material, e.g., activated carbon, together with an upper layer of fiberglass batt. These two materials form the center of a metal panel sandwich, with the activated carbon serving as a barrier to radiant thermal transmission through the panel, and as a getter, and with the fiberglass batting (222a) serving to filter the particulate material to prevent it from leaving the panel when the panel is placed under a vacuum, for wiping the sidewalls of one of the panels when the panels are assembled, and for preventing the compressed particulate material from entering the peripheral area of the panels which ar welded together to form a complete panel. In a further embodiment of the invention, the cake within the cavity is a sandwich comprising a layer of compressed activated carbon (222b) positioned between two layers (222a, 222c) of compressed fiberglass.

Title: Refuse compactor with folding compaction plate
Inventor: FOX ANTHONY
IPC: B30B9/30
Filed: 1995-11-16
Abstract: A refuse compactor especially designed for fast food restaurants is of a predetermined limited height dimension allowing its upper surface to function as a serving tray storage rack.   The refuse compactor is characterized by having a foldable compaction plate driven by a hydraulic ram.    When  the  compaction  plate  is  elevated  to  its uppermost position, it is folded in a way that does not interfere with the opening of the refuse entry door.  When moving  through  its  compaction  stroke,  the  foldable compaction  plate  becomes  locked  in  a  flat,  planar configuration.   In this way, it is unnecessary to locate the compaction plate above the refuse entry door, thereby providing a lower profile to the refuse compactor cabinet.
