Title: Garbage bag holder
Inventor: CELLI GIULIANO
IPC: B65B67/12
Filed: 1986-05-12
Granted: 1991-02-26
Abstract: ABSTRACT OF THE DISCLOSURE          A bag support for engaging a garbage bag or other large bag typically used around a house, includes a generally circular rim for maintaining the mouth of the bag open and at least three support legs disposed about the rim and pivotally connected thereto.  The legs are collapsible to a storage configuration with the length of each leg being reduced by at least 50% and movable to a storage position.  The pivot connection of the rim and legs allows movement of the legs into the general plane of the rim with the legs in the collapsed state.  The legs are thus moved and generally fit interior to the rim to provide a compact storage arrangement.  The legs are disposed below the upper edge of the circular rim to leave the upper edge clear for firmly engaging the bag.  The structure is easily manufactured, effective in use and easily stored in a compact state.

Title: Helical-scan-type video tape recorder
Inventor: NAKAMURA SHINJI
IPC: H04N5/928
Filed: 1986-07-15
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE          A helical-scan video tape recorder (VTR) records time-axis-compressed PCM audio signals on auxiliary recording tracks on a recording medium and has a synthesization circuit which mixes normal frequency-modulated audio signals (AFM audio signals), recorded on video tracks with video signals, with the time-axis-compressed Pulse-Code-Modulated audio signals (PCM signals) before reproduction through speakers.  The PCM audio signals require digital processing for time-axis compression, and so are recorded and reproduced later than the AFM audio signals.  Thus, when reproduced, the PCM audio component lags behind the AFM component, resulting in an echo effect.  Adjustment of the relative amplitude levels of the two types of audio during synthesization produces acoustical effects that simulate the acoustics of a concert hall.
Patent CA-1300441-C (CA)
Title: Wood preservation system
Inventor: LOTZ W ROBERT
IPC: B27K3/50
Filed: 1986-08-12
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE     Wood which is relatively poorer in connection with its ability to resist weathering, rotting, insect attack, etc., is made more resistant to such factors by a two-step process.  The first step is to impregnate the poorer quality wood with an aqueous solution of tannin extract taken from a plant species which has superior weathering and other resistance properties.  The wood treated with the tannin extract is then further treated with an aqueous solution of a fixative to prevent leaching of the extract during use of the wood, e.g., in exterior applications.          The process of the present invention not only results in preservation of the wood, but can also be used for purposes of coloring the initial wood product.  Abundant and relatively cheap woods can then be converted into wood products having qualities more closely like those of more expensive woods.  In addition to the above-noted advantages, the present invention also uses treating substances which are non-hazardous and which are not damaging to the environment.  (Metallic salt solutions may also be employed for coloration and for providing additional decay resistance.)

Abstract: ABSTRACT OF THE DISCLOSURE     A computer controlled rental and sales system and method for a supermarket and the like allows a customer to purchase or rent items from a locked cabinet without the intervention of store personnel.   The authorized customer first inputs a membership card and a secret number.  If these are correct, the system un-locks the locked cabinets, whereby the customer is allowed to examine all of the contents in the unlocked cabinet at his or her leisure.  The computer continously monitors the removal of all items from the unlocked cabinet.   The customer reads in identifying information from each of the selected items.   The computer prevents the cabinet from being relocked unless the number of items that have been removed equal the number of items that have been read in by the customer.   When the number of items equal, the doors of the cabinet are relocked, and the cus-tomer is provided with a customer slip indicating the items that have been selected.   The system and method can be utilized in a sale or rental context.  In the rental context, return of rental items can be performed in parallel with rental of items.   High security is achieved without employee monitoring since the customer is held responsible for all items removed during the time that the cab-inet is unlocked.
