Abstract: A method of sealing a peelable lid (7) to a package is disclosed.  The package contains a base (1) and a potentially rupturable flexible web (5) of plastics material covering the base (1) which together define a sealed space therebetween. The lid (7) is in turn sealed above the flexible web (5). The method comprises the steps of: 1) placing a lid (7) over a thin flexible web (5); 2) sealing the lid (7) to the thin flexible web (5) over the base (1) with a strip like seal (13) which extends around the perimeter of the space so the lid (7) will be sealed at the same region as the thin flexible web (5) is sealed to the base (1). The sealing is achieved by a thermosealing process which provides a temperature gradient across the width of the strip like seal (13) during the sealing process. This, in turn, provides the seal (13) with a peelable adhesion gradient across its width so that when the lid (7) is stripped from the package, it will be unlikely to rupture the thin flexible web (5). A package made by the method is also disclosed.

Title: Seat belt retractor
Inventor: NAKAYA HIDEKAZU
IPC: B60R22/405
Filed: 1993-09-07
Abstract: This invention relates to locking means of a seat belt retractor equipped with an emergency lock which in an emergency locks the withdrawal of webbing.      The locking means of this retractor comprises a ratchet wheel (16) and a pawl (32); the pawl comprises two teeth, and the pawl and the ratchet wheel are positioned in such a way that when the load on the webbing is relatively small only one of the teeth of the pawl engages with a tooth of the ratchet wheel and there is a small gap between the other tooth of the pawl and the tooth of the ratchet wheel corresponding thereto and when the load on the webbing is relatively large both of the teeth of the pawl engage with teeth of the ratchet wheel.      As a result, because the load on each tooth is half of what it is when the pawl has one tooth only, twice the torque can be withstood and the diameter of the ratchet wheel can be reduced.

Title: Insulated rail electrification system
Inventor: CLARKE ROBIN
IPC: B60M1/34
Filed: 1994-08-22
Abstract: An electrical rail conductor assemblage for an in-sulated electrification system, including an elongate electrically-conducting rail having a longitudinal groove for receiving a cooperable collector shoe and for guiding it for travel along the rail. The rail has oppo-site wall portions which border the groove. The wall portions have thin wall sections with rounded longitudinal edges that constitute the mouth of the groove of the rail. The rail is covered by an essentially tubular, insulating, hollow, resilient and rigid cover member enveloping essentially all portions of the rail except for the mouth of the groove thereof. The cover member has a longitudinal cut which registers with the mouth of this groove, and curved, longitudinally-extending snap-on retainer portions that extend along the cut and are adapted to snap over the rounded longitudinal edges of the rail. These retainer portions extend in a circumfer-ential direction through substantially a full semi-circle.      The advantage of the present constructions is that these retainer portions have exterior longitudinal flanges which constitute offset extensions of the opposite wall portions of the resilient cover member, to thus minimize access to the metal of the rail, and reduce the chance of inadvertent electric shock from an electrically live rail.

IPC: H04B3/46
Filed: 1993-02-03
Abstract: ABSTRACT OF THE DISCLOSURE            PROCESS FOR DETECTING NON-LINEAR BEHAVIOR IN A DIGITAL DATA TRANSMISSION PATH TO BE EXAMINED      The transmission path (4) is fed with a test signal (M'), which is generated from a sequence (m) of spectral components (S1...S10), which are distributed equidistantly in the frequency range, as the result of combining with an additional function (ZSF). The additional function (ZSF) is selected so as to allow the test signal (M') to contain, besides the spectral components (S1...S10) of the sequence (m), additional spectral components (ZS1...ZS21). An output signal (M") received on the output side of the path is evaluated at evaluation frequencies (AW1...AW10), in the case of which the test signal (M') is free per se of spectral components and, in the case of which, the test signal (M'), after a self-convolution, exhibits additional spectral components (SA1...SA10). The additional spectral components (SA1...SA10) occurring at the evaluation frequencies (AW1...AW10) allow a non-linearity of the transmission path (4) to be immediately detected.
