Title: Hockey stick bag
Inventor: GRECO FRANK P
IPC: A45F5/00
Filed: 1994-06-29
Abstract: There are a number of hockey stick bags on the market that are designed with a shoulder strap for the player to carry. This type of hockey stick bag does not take into account how the sticks are positioned inside the bag for ease of carrying and that the player may find it cumbersome having to lug around two separate equipment bags; one with his/her hockey equipment and the other for the hockey sticks. In this invention, we have designed a hockey stick carrying bag that will meet the need of hockey players and reduce having to carry two separate bags for equipment. The hockey stick carrying bag is designed to the actual contour of a hockey stick as indicated by the heel to toe section of the bag (Attachment A). To further enhance the portability and uniqueness of the hockey stick bag, we have eliminated the shoulder straps and inserted two heavy duty velcro strips designed to wrap around the carrying straps of a hockey equipment bag. This concept makes the hockey stick carrying bag part of the over-all equipment bag, thus the player only has to carry one bag.

Title: Method of recovery of elastic clips used for fastening rail-road rails
Inventor: CIECIELSKI EZILDO
IPC: E01B9/30
Filed: 1994-11-03
Abstract: ABSTRACT OF THE DISCLOSURE   Method of recovering elastic clips used for fastening railroad rails, which comprises the stages of: 1. Recovery itself: first a cleaning, to remove oil andgrease; then the clips are classified according to the measurement of distance (C) between the legs (2 & 3) of the clips, of displacement (H) between the extremities (4 & 5) of the legs and of inclination of ( .alpha. ) of the legs in regard to the vertical axis of the clip, being then annealed in order to remove the effects of thermic treatments or tensions due to mechanical stresses which they suffered in gettingdistorted. 2. Gauging: first step is heating the clip to a temperature that renders it malleable; then it is pre-gauged to the measure of distance (C) between the legs, being the clip afterwards gauged into its initial design condition; 3. Thermic treatment, whereby the clip receives a hardening to improve its mechanical properties, followed by a surface hardening to relieve stresses; 4. Finishing, which is a preparation for painting, through a cleaning by mechanical scraping; a cold distortion - called pre-load - that sets the displacement (H) between the extremities of the legs in such a measure that, when the clip is assembled, it presents an ideal load for fastening of the rail; and finally, phosphatization and painting proper.
