Title: Resin blends of maleic anhydride grafts of olefin polymers for extrusion coating onto metal foil substrates
Inventor: TABOR RICKY L
IPC: B32B15/08
Filed: 1991-11-18
Abstract: ABSTRACT       Succinic acid or succinic anhydride grafts of HDPE were blended with LLDPE, especially ethylene/ 1-octene copolymers, to form blends having useful adhesive properties at elevated temperatures.  The succinic acid or succinic anhydride groups were provided by grafting, respectively, maleic acid or maleic anhydride onto HDPE. The resin blends were useful for coating metal foil substrates.  The adhesion of the resin blend to the metal foil substrate is particularly good at elevated temperatures (e.g., temperatures above 60°C).

Title: Device for relief of back pain
Inventor: BOLAND KEVIN O
IPC: A61H1/02
Filed: 1992-03-03
Abstract: ABSTRACT OF DISCLOSURE   A device for supporting one's thighs, knees, calves, and feet to obtain relief and comfort from low back pain.        The device permits the user to be placed in the correct position to strengthen the stomach muscles without risking injury to the back.   When a prone user disposes his thighs at a 32 degree angle  to the  vertical,  the  lower  spine  is  partially flattened and the lower back muscle tension is reduced.  The curved areas of the support under the knees and heels, and in the same horizonal plane, provide a comfortable transition from the thigh supporting surfaces to the calf and foot supporting areas.   The horizontal surface is depressed intermediate to its length and creates a final subtle incline to receive the calf muscles.  The unit is customized to the user's leg length measurements.

Inventor: TAMEZ FEDERICO G
IPC: F16F15/023
Filed: 1992-05-29
Abstract: A damping subsystem protects a structure from the effects of seismic disturbances and employs at least a first pair of first and second damping and transformation mechanisms including respective, associated first dampers oriented in parallel relationship in a first direction and oppositely disposed relatively to the center of gravity of the structure and mechanically connected between respectively corresponding portions of the structure and the foundation in relatively inverse relationship.  Each mechanism transforms a force transferred to the associated first damper from the foundation in the first direction and/or any lateral, relative displacement of the corresponding structure and foundation portion in the first direction to a corresponding force and/or displacement, respectively, in a second direction perpendicular to the first direction, each also performing the reverse transformation.  A mechanical interconnection between the first and second damping and transformation mechanisms transfers any such transformed force and/or displacement of the second direction from one to the other of the pair of first and second damping and transformation mechanisms, thereby to impede rotation of the structure relatively to the foundation.  The respective, associated first dampers of the pair of mechanisms provide individually controllable damping of lateral displacement between the corresponding structure and foundation portions in the first direction.
Patent CA-2076039-A1 (CA)
Inventor: VOLEJNIK WILHELM
IPC: H04J3/06
Filed: 1990-12-04
Abstract: In the bytewise stopping of synchronous signals in the synchronous-digital-multiplex hierarchy, fitter with phase jumps of 8 U~ occurs which renders beat recovery difficult. Means are therefore sought for converting fitter into drift. This is achieved with a phase regulating loop (PLL) in which a phase jump compensator (7) is inserted between the output (4) of a phase discriminator (3) and the input (5) of an oscillator (b). This converts an input correction value (14) into an output correction value (Ka). If there is no stop, the input correction value (K ~) leaves the phase jump compensator (7) unchanged (a1, b1). If a positive stop is made (+St), the pulses of the input correction value (K~) thus lengthened are first shortened to the normal duration (x1) and then lengthened stepwise (c1, d1) to the original duration. On negative stopping (-St) the thus shortened pulses of the input correction value (K~) are first lengthened to the normal duration and then reshortened step-wise (e1, f1).

Inventor: BRANDTS MICHIEL P
IPC: B21J15/36
Filed: 1992-02-18
Abstract: The invention concerns a method (device and product) for riveting a packet (50) of sheets (51, 52) by means of unannealed aluminium rivets made from an alloy harder than that of the relatively soft AD rivets in common use; this method is characterized by the fact that the expansion of the head to be formed at the shank end (58, 59) of the rivet during the riveting process is controlled by a snap-tool (62) which encloses the shank end (58, 59) at first loosely. When the expansion of the head diameter approaches D =  1,5 d (with d the rivet diameter), i.e., the limit above which cracks form in the head, the tool (62) prevents further deformation and forces the material of the head to deflect towards the central portion of the rivet shank (57) which subsequently expands and widens the hole (53) sufficiently to make the riveted joint last considerably longer. The good loosely and, later in the process, tightly fitted enclosing of the shank end (58, 59) by the snap-tool (62) allows the riveting to be done manually. This can still be improved further by using a snap-tool (62) with a profile (67, 68, 69) complementary to the contour of the shank end (58, 59).
