Title: Liquid dishwashing detergent composition
Inventor: PATEL AMRIT M
IPC: A61K8/31
Filed: 1990-06-20
Abstract: ABSTRACT OF THE DISCLOSURE:         A liquid dishwashing detergent composition for hand washing of dishes is described, which is mild to human hands and leaves the skin thereof noticeably smoother than conven-tional and control liquid dishwashing detergent compositions.          The invented dishwashing composition includes 5 to 40% of synthetic organic detergent of the anionic and/or nonionic types, which preferably is a mixture of such types, 0.1 to 10% of a skin smoothening compound which is a hydrocarbon, an organic acid, an ester, an amide, an amine, a quaternary ammonium compound, or an alcohol, or any mixture thereof, each of which includes in its formula a hydrocarbyl chain of at least 25 carbon atoms, in an aqueous medium.  Preferably, the detergent component is a mixture of sulfated and/or sulfonated anionic detergents, such as linear higher alkylbenzene sulfonate and higher fatty alcohol poly-lower alkoxy sulfate, or is a nonionic detergent or a mixture of a nonionic detergent, such as a condensation product of a higher fatty alcohol and lower alkylene oxide, with a sulfated and/or sulfonated anionic detergent, the skin smoothening compound includes a normal alkane of 25 to 50 carbon atoms and the proportions of synthetic organic detergent, normal alkane skin smoothening compound and aqueous medium are in the ranges of 5 to 35%, 0.2 to 5% and 50 to 80%, respectively.          Also within the invention are a process for hand washing dishes with the invented composition, dissolved in water to form a mild dishwater, which leaves the hands feeling smoother and non-greasy, and a process for manufacturing the invented composition, which latter process is important to produce such compositions having the desired hand smoothening and non-greasy characteristics.
Patent CA-2021209-A1 (CA)
Inventor: MCDONALD BRIAN A
IPC: F23D14/58
Filed: 1990-07-16
Abstract: ABSTRACT    In a metal burner for gas appliances, this invention can create  detailed  flame  patterns  with  a  minimum  of  hole punching. The burner can vary the flame height, width and location of the flames by varying the size of only a few slots. In this invention, a piece of sheet metal with a series of slots that may be inches in length and may vary in size is used as an overlay and attached to a piece of perforated sheet metal stock with a plurality of small uniformly spaced holes. As few as ten of these slots may contain in excess of 1,000 gas outlet ports. This lamination of metal forms part of the body  of  the  burner  which  is  an  enclosed  chamber.  For additional flame control, gas is directed into the burner through a round metal tube which terminates directly in front of a contoured dispersement fitting of approximately the same diameter  of  the  tube.  The  orientation  of  this  tube  and dispersement  fitting affects the dispersement  of the gas inside the burner resulting in changes in flame height.

Title: Method of and apparatus for automatically analyzing the degradation of processed leaf tobacco
IPC: G01N5/00
Filed: 1990-08-01
Abstract: ABSTRACT OF THE DISCLOSURE      A method of and apparatus for automatically analyzing the degradation of processed leaf tobacco are disclosed. The apparatus comprises a conveyor system for diverting a sample of leaf tobacco from an operating tobacco processing line, supplying the tobacco to a degradation analyzer and returning the tobacco to the processsing line after the degradation analysis has been performed.  The degradation analyzer comprises a weigh conveyor for receiving the tobacco  sample,  weighing  it  to  insure  it  is  within prescribed limits and delivering it to a vibratory screen separator where the tobacco is separated into a plurality of fractions of different sized tobacco particles.   The separated  fractions  are collected  in  weigh  buckets, electronically weighed  and discharged  to the  conveyor system for return to the tobacco processing line.   A microprocessor controls the operation of the apparatus and, based on the weights of the tobacco fractions, calculates the percentage by weight of each tobacco fraction to the total weight of all fractions.   The distribution of the weight percentages is indicative of degradation of the leaf tobacco being processed.

Patent CA-2023570-A1 (CA)
Title: Blade sharpener
Inventor: PETROFF CVETAN
IPC: B24B/
Filed: 1990-08-17
Abstract: A B S T R A C T       A blade  sharpener  having a sharpening mechanism which functions to sharpen a blade engaging that mechanism and being moved  longitudinally  relative  thereto.   The  sharpener  also includes sharpening defeating means which, when operative,  at least inhibits and possibly prevents sharpening of a blade by the   sharpening   mechanism   when   that  blade   is   moved longitudinally through  the  sharpener in one direction.   The defeating means is responsive to blade movement so as to adopt an  operative  condition  when  the  blade  is  moved  in  the aforementioned  one  direction,  and  to  adopt  an  inoperative condition when the blade is moved through the sharpener in the opposite  direction.   The  defeating  means  includes  a  blade engaging  member  such  as  a  roller,  and  in  the  operative condition that roller engages and presses against the cutting edge of the blade so as to impose a force on the blade which acts counter to the force  causing  the  blade  to  engage  the sharpening mechanism.   The counter force therefore tends to push the blade out of contact with the sharpening mechanism. The roller does not engage the blade,  or at least does not apply the counter force, when the defeating means is  in the inoperative condition.  An anti-bottoming groove is provided around the circumferential surface of the roller to provide a location  for  the cutting  edge  of  the knife blade and that groove is formed to avoid contact between the actual cutting edge of the blade and the base of the groove.
