Filed: 1990-05-10
Abstract: Improvements are provided herein in tensioners for power transmission belts, in a method for making such tensioners, to annular pads which are made of friction material for such power transmission belts, and to methods for making such annular pads. In one embodiment, the tensioner includes a support to be fixed relative to the belt. A belt-engaging element is carried by the support and is movable relative thereto. First springs are operatively-associated with the support and with the belt-engaging element for urging the belt-engaging element relative to the support and against the belt with a force to tension the belt. Frictional dampeners are operatively associated with the support and with the belt-engaging elements relative to the support in at least one direction of movement thereof. The dampeners have a longitudinal axis. The support includes a shaft having a longitudinal axis, which is fixed from movement relative to the belt-engaging elements. The belt-engaging elements have a portion thereof which is rotatably carried by the shaft so as to rotate relative to the shaft. The dampeners include a pan of fractionally-engaging, first and second parts. The first part comprises an annular pad of friction material that is coaxially disposed and is axially movable on the shaft relative to the second part. Second springs urge the first part against the second part with a certain spring force. The first part of the dampener has a guide thereon. One of the supports and the belt-engaging element have openings therein that receive the guides therein to guide axial movement of the first part. The improvement is provided by forming the annular pad and the guides of the first part of the dampener as a one-piece homogeneous member.

Title: Piggy-back reflective 5330
Inventor: LONGTIN ANDRE G
IPC: B60R13/00
Filed: 1992-08-21
Abstract: A method of making reflective decals, such as for use on automobile license plates, allows one to utilize conventional reflective face stock, yet in a mechanized and efficient manner affix a decal to a carrier for mailing. A standard web of reflective face stock, adhesive, and first liner is coated with a second adhesive layer (on the first liner) and a second liner is applied. The web is printed and dried, as with UV ink and by UV drying. Sequential numbers can be applied by printing, as can an expiration year, etc. The web is then die cut to separate a matrix containing reflective stock, first adhesive, first liner, and second adhesive, from surrounding printed decals, the decals spaced from each other and connected by the second liner (e. g., 1.5 mil silicone coated polyester). The matrix material is removed from the web by winding it up into a roll, and the web is taken up, and then ultimately handled by conventional labeling equipment to affix individual decals (by the second layer of adhesive) to individual carriers. The printed web can also be acted upon to flood coat the face stock with scuff resistant UV overprint varnish, and then UV drying the varnish.

Title: Process and apparatus for measuring small quantities of light
Inventor: SCHENKEL PAUL
IPC: H03F3/08
Filed: 1992-08-24
Abstract: PROCESS AND APPARATUS FOR MEASURING SMALL QUANTITIES OF LIGHT            ABSTRACT   A light receiver converts light to be measured into an electrical signal, which during a measuring interval is integrated into a measuring signal. In a first time segment a first mean value signal is formed, corresponding to the mean value of the measuring signal over the first time segment. In a second time segment of equal duration, a second mean value signal is formed within the same measuring interval, corresponding to the mean value of the measuring signal over the second time segment. Finally a difference signal is formed corresponding to the difference of the two mean value signals and constituting a measure of the light received. The difference signal is passed on for further signal processing.                (Fig. 1)

Patent CA-2107982-A1 (CA)
Inventor: NAKAJIMA AKIHISA
IPC: H04M3/42
Filed: 1993-10-07
Abstract: The present invention relates to a connection control method for personal communications. In accordance with the present invention a switching center which is comprised of a first memory part, a second memory part and a third memory part. The first memory part stores a terminating terminal number which corresponds to each subscriber. The terminating terminal number is registered by each subscriber. The second memory part stores idle/busy information corresponding to each terminal. The third memory part stores idle/busy information corresponding to each subscriber. When a subscriber makes a call at a terminal, the switching center determines whether the idle/busy information for the subscriber stored in the third memory part is busy or idle. When the idle/busy information represents an idle, the switching center refers to the idle/busy information for the terminal stored in the second memory part. When this idle/busy information represents idle, the switching center interrogates the terminal number of a terminating terminal of a terminating subscriber stored in the terminating terminal memory part, i.e. the first memory part, and performs an outgoing call connection process. At this point, the switching sender also sets the idle/busy information for the subscriber and the terminal to a busy state. When the subscriber makes a call, while the terminating terminal is performing an incoming call connection process for the subscriber, since the idle/busy information for the subscriber has been set to the busy state, even if the terminal is idle, the switching center does not perform an outgoing call connection process for the subscriber at the terminal.
