Abstract: An apparatus is disclosed for the cold, inplace recycling of asphalt paving of an asphalt roadway. The apparatus is self-propelled, and it includes a cylindrical milling drum mounted at a medial location along its longitudinal length and which serves to remove a thickness of the asphalt paving and break the same info particles as the apparatus moves forwardly along the roadway. The particles are lifted to a separating screen which is positioned forwardly of the drum, and the particles are thereby separated into a first portion of relatively small particles suitable for recycling and a second portion of oversized particles. The first portion is delivered to the rear end of the apparatus where it is mixed with a suitable liquid additive, and then discharged onto the roadway.    A following payer then forms the discharged material into new paving. The second pardon of oversized particles is discharged onto the roadway at a location in front of the milling drum. Thus the milling drum again contacts the second portion upon forward movement of the apparatus, and the drum acts to further crush the particles and cause them to be recycled through the apparatus.

Title: Production of plastics material incorporating starch
Inventor: GRIFFIN GERALD J L
IPC: C08G81/00
Filed: 1990-09-11
Abstract: A filler for plastics material comprises natural starch which, before admixture with synthetic resin, is treated in a solution of calcium hydroxide or other alkali-earth metal hydroxide or of a metal hydroxide coordination complex having an alkaline character and is subsequently washed and dried before mixing with the molten resin. In a method utilising the invention the resin comprises a polymer or copolymer which affords carboxylic acid groups. A  strong bonding of the resin with the starch particles results which improves the strength of the filled plastics, as compared with the corresponding plastics having an untreated starch filler.

Abstract: An endoscopic clip applying system as described which contains a venting system and a clip applying support system which prevents closure of the mechanism before firing. The applier's jaws are spaced apart no further than the width of the applier shaft, even when holding a clip. Also, the system ensures proper loading of the clips and prevents them from falling out during loading.     Further, the system describes an easily manufacturable, positively opening system which has minimized size requirements. Furthermore, a lock-out mechanism is provided so that the mechanism may not be inadvertently fired. The shaft resists excessive torque as well as holds the clip in place during firing. There are provisions for sealant and non back-up of the clips, as well as features which make the clip properly placed for closure. In an alternate embodiment, the clip applier shaft rotates about its handle mechanism.

Abstract: In order to initially point a directional antenna mounted on a mobile unit to a stationary satellite, the antenna is rotated one revolution in azimuth.  While the antenna rotates, the maximum receive signal strength is detected together with the angular position of the antenna at which the maximum strength has been ascertained.  Subsequently, the antenna is rotated to the angular position which has been determined in the preceding operation.  If the angular position is determined correct (viz., the mobile unit is detected to be synchronized with the satellite), then the initial antenna beam orientation is terminated.

Abstract: ABSTRACT     A surgical scalpel (10) is provided with a retractable guard (11) for its cutting blade (12). The guard (11) is mounted on the handle (24) of the scalpel (10) for sliding movement between an advanced position in which the blade (12) is covered and a retracted position in which the blade (12) is exposed --- with the use of only one hand --- and without requiring the surgeon, nurse and/or assistant to take his or her eyes away from the patient or the instrumentation during a surgical procedure.  A two-position detent means (28) includes a resiliently-biased manually-releasable detent member (29) disposed within the longitudinal center plane (30) of the handle (24) and extending above the handle (24).  A cut-out (49) on the bottom wall (15) of the guard (11), together with the detent member (29), facilitates the one-hand actuation of the guard (11).  A stop means (25, 26) between the guard (11) and the handle (24), which is independent of the detent means (28), limits the sliding movement of the guard (11).

Title: Ice hockey skate
Inventor: GRAF KARL
IPC: A63C1/32
Filed: 1993-02-24
Abstract: The blade of an ice hockey skate, which blade consists of a plastic material blade body and a runner body made of metal, must be exchanged from time to time due to damages suffered. Until now this was a quite in-trinsic procedure and the exchanging had to be made at the manufacturer of the ice hockey skate because the blade is mounted to the boot by tubular rivets. Here, the blade is mounted to the shoe by means of such nut and bolt mounting devices which are in a position to take up the considerably higher loadings encountered at ice hockey skates in comparison with figure skating or ice dancing ice skates. The nut of the mounting device is a special structural member which is separate from the shoe sole and consists preferably of a metal.

Abstract: A resistance welding gun which is adapted to prevent asymmetrical impacting of two or more metal sheets to be welded.  The resistance welding gun includes a pair of rotatably connected arms, each of which has a corresponding working end and actuation end.  An electrode tip is located at each working end to provide a pair of opposed welding electrodes, while a cylinder is attached to the actuation ends of the arms to provide rotation therebetween.  Between the actuation ends there is provided an equalizing mechanism including a crank and a pair of linkages which serve to equalize the movement of the arms about their pivot. In cooperation with the pivot of the arms, the crank establishes a fixed or datum point at which the electrode tips of the resistance welding gun are targeted such that, when properly positioned on opposite sides of the metal sheets, the electrode tips contact the metal sheets substantially simultaneously and apply substantially equal forces to the opposite sides of the metal sheets.  As a result, the equalizing mechanism substantially prevents unilateral contacting and asymmetrical impacting by the electrode tips on the metal sheets.
