Novel substituted benzoic acid 1 and 2-alkyl and 2-cycloalkylhydrazides effective as insecticides or intermediates for the preparation of insecticidal diacylhydrazides also are presented.

Abstract: METHOD OF IMPROVING THE FORMATION EFFICIENCY OF POSITIVE PLATES OF A LEAD-ACID BATTERY                 ABSTRACT OF THE DISCLOSURE   The formation efficiency of passed positive plates of a lead-acid battery is greatly enhanced by providing in situ a layer of lead dioxide (PbO2) on the pasted plate surfaces prior to formation.  The PbO2 layer is preferably formed by treating the surfaces of the plates with an ozone-enriched gas to convert a portion of the poorly conductive positive active precursor material (nPbO?PbSO4) to electrically conductive PbO2.  In subsequent electrochemical formation of the plates, the total formation charge can be reduced significantly while obtaining more complete conversion of the paste to positive active material.  The method also provides an effective substitute for conventional curing of pasted positive plates.

Title: Externally retractable sunroof assembly
Inventor: DRAPER DAVID L
IPC: B60J7/043
Filed: 1987-01-14
Granted: 1992-01-28
Abstract: EXTERNALLY RETRACTABLE SUNROOF ASSEMBLY        ABSTRACT         An externally retractable sunroof assembly (14) is mounted on a vehicle roof (12) between upper edges of side doors (24).  A roof opening (60) in the outer roof panel (32) has forward and rearward edges and has side edges exposing the interior of the roof side rails  (44)  in  which  a  pair  of tracks  (68)  are respectively mounted.   A sunroof (70) has side edges (72) respectively mounted by the pair of tracks within the side rails and is movable between a closed position closing the roof opening and an externally retracted position above the outer roof panel to the rear of the roof opening.  The sunroof (70) is made from metal or glass and has the side edges thereof in the closed position located adjacent the upper edges of the side doors to provide a continuous door-to-door appearance. The longitudinal and lateral dimensions of the sunroof (70) with the construction disclosed provide maximum roof opening while still permitting storage of the opened sunroof on the roof.  the sunroof assembly (14) is installed by cutting the roof opening (60)  in the outer  roof  panel  (32)  of  the  manufactured vehicle without any other structural removal so as to maintain the strength of the roof.

Title: Mist cultivation of cells
Inventor: WEATHERS PAMELA J
IPC: C12M3/00
Filed: 1987-02-19
Granted: 1991-12-03
Abstract: ABSTRACT OF THE DISCLOSURE            Cells are cultivated in a chamber having a high nutrient humidity.          Gas drives liquid nutrient through devices which produce a fine mist within the chamber.  Screens or convoluted mesh supports the cells, and provides for drainage of cell products and media away from the cells for processing.  The chamber is sealable to provide for axenic conditions.

Title: Method of enclosing an object within a homogeneous block (1)
Inventor: HUGHES JOHN T
IPC: H01H69/02
Filed: 1987-04-15
Granted: 1992-10-20
Abstract: ABSTRACT     A method of enclosing an object (5), such as an electronic component,  within  a  homogeneous  block  of  microporous thermal  insulation  material  comprises  charging  a  first predetermined  amount  of  a  loose  microporous  thermal insulation mixture  (2)  into a die  (1) and compacting the insulation mixture into a block for supporting the object to  be  insulated.   A  recess  (4)  may  be  formed  in  the compacted mixture for receiving the object (5).  The object (5) is then located on the compacted mixture and a second predetermined   amount   of   loose   microporous   thermal insulation mixture  (6)  is charged into the die  (1).  The loose insulation mixture (6) is compacted against the block of already compacted insulation material  (2) which causes the two charges of insulation mixture to merge and to form a homogeneous block enclosing the object.
