Patent CA-2158900-A1 (CA)
Inventor: HALONEN TUOMO
IPC: B65B47/00
Filed: 1995-09-22
Abstract: A machine and a method for making a plastic film pouch and attaching a spout thereto is described. Two overlaid film sheets are guided adjacent a spout base positioner to position a dispensing spout spaced adjacent one of the two overlaid film sheets at a predetermined position with respect to a sealer device. One of the overlaid film sheets is displaced in the area of the sealer whereby the spout base can be sealed to a single one of the overlaid sheets. A cap may be secured to the spout, and the sheet to which the base of the spout is attached may also be punctured if desired. The overlaid sheets are unconnected at one of their edges whereby the sheets can be guided over one or more liquid spouts for filling the pouch after a bottom seal and a side seal is formed. The filled pouch is displaced for further sealing of its top open end and detachment from the overlaid sheets prior to discharge of the filled pouch on an outlet conveyor where the filled pouch with the spout attached thereto is discharged.

Title: Method and equipment for testing a speed limiter of a lift installation
Inventor: LIEBETRAU CHRISTOPH
IPC: B66B5/06
Filed: 1996-02-16
Abstract: In this equipment for the testing of a speed limiter, a wheel axle (5) of a drive wheel (6), which engages into a cable groove (7) of a cable guide roller (8) and drives this, is clamped into a drill chuck (4) of a drilling machine (1).  The cable guide roller (8) is a component of the speed limiter to be tested.  For testing the speed limiter, the limiter cable is taken off from the cable guide roller (8).  Then, the cable guide roller (8) is driven at a linearly rising speed by means of the drive wheel (6) up to the triggering point of the speed limiter.  The movement of the drive wheel (6) is detected and evaluated by means of an evaluating device (9) with an opti-electronic  system  (10)  arranged  at  the  drilling  machine  (1). Reflectors (11) arranged at the drive wheel  (6) reflect light (12), which is emitted by the opti-electronic system (10) and picked up and evaluated  in  the  form  of  light  reflections  (13)  by  the  opti-electronic system (10).  The speed of the cable guide roller (8) is increased by the drilling machine (1) by way of the drive wheel (6) up to the triggering point of the speed limiter.   The triggering instant is detected by an acceleration sensor (16) connected with the speed limiter.

Title: Liquid fabric softener dispenser for automatic washing machines
Inventor: WILSON STEVEN R
IPC: D06F39/02
Filed: 1996-02-19
Abstract: A liquid fabric softener or treating liquid dispenser for a washing machine having a parabolic or egg-shaped body portion from which radially extends an annular rim portion. The rim portion rests upon a top surface of an agitator and is held in place thereon by a removable, resiliently press-fit cap.   The rim portion has a series of bosses extending upwardly therefrom and a series of notched openings formed therein.   The bosses space the cap member from the upper surface of the rim portion.  During operation of the washing machine in a spin cycle, treating liquid within the body portion of the dispenser flows upwardly along an inner surface of the cup body, downwardly through the notched openings in the rim portion, and into a holding chamber provided within the hollow interior of the agitator.   The holding chamber retains the treating liquid until the rotational speed of the agitator slows to a predetermined rate at an end of the spin cycle, and thereafter dispenses the treating liquid down the hollow interior of the agitator, through openings in a bushing and a bottom of a perforated inner wash tub, and into the outer wash tub wherein it is mixed with rinse water and subsequently delivered to the clothes within the inner wash tub in a diluted condition.

Abstract: A method of organizing electronic documents for storage and subsequent retrieval, involves storing a summary structure describing the structure of summary recordsassociated with each document. Each structured summary record has at least one field representative of a characteristic of the document. A predetermined number of field values identify the value of the characteristic associated the field. Predetermined keyword criteria associated with the field values are stored. Each document is analyzed to build a text index listing the occurrence of unique significant words in the document. The text index is compared with the keyword criteria to determine the appropriate field value for the document. For example, one characteristic field might related to topic, which could have the field values of "financial" or "sports". The preponderance of certain keyword criteria, such as "money" or "shares" would identify the document with the financial topic.
