Title: Peg device for use in tensioning drum skins and to novel shaped drums using the peg device
Inventor: GOLDIN DARREN BRETT
IPC: G10D13/02
Filed: 1997-01-14
Abstract: Disclosed is an elongate peg, preferably of wood, which has lips or shoulders generally perpendicular to the length of the peg body and adjacent opposite ends. The lips or shoulders are on opposite sides of the peg body. The peg is used to tighten or tension the vertical lacing in "bongo" type drums by contacting adjacent pairs of vertical lacing with the peg whereby each lip is in contact with one of the adjacent pair of vertical lacing so that when the peg is flipped generally horizontal end forward, a twist is formed in the lacing pair a t one end of the peg held by the lip while the other end of the peg is forcibly held against the drum shell by the force in the twist. In a preferred aspect, the dru m profile is such that the spacing between the vertical lacing and the drum shell is increased slightly to facilitate more easily the flipping of the peg but still r etain a peg end in forceable contact with the shell once flipped.

Title: Poudre frittable semi-cristallisee; article obtenu avec cette poudre
Inventor: DICKENS ELMER DOUGLAS JR
IPC: B29C67/00
Filed: 1995-08-29
Abstract: On a préparé un produit possédant des propriétés uniques à base d'une poudre pouvant être frittée au laser, ce qui permet à la poudre d'être frittée dans une machine sélective de frittage au laser, afin d'obtenir une pièce frittée, dont la densité est quasi-totale. Dans la plupart des cas, on ne peut distinguer la pièce frittée d'une autre pièce possédant les mêmes dimensions et fabriquée par moulage isotrope de la poudre. En plus de sa caractéristique coulante à une température proche de sa température de ramollissement, cette poudre est répartie en deux couches dans lesquelles presque aucune particule primaire ne possède un diamètre moyen supérieur à 180 µm, étant donné, de plus, que le rapport numérique moyen de particules inférieures à 53 µm est supérieur à 80 %, la dimension du reste des particules plus importantes se situant dans une plage de 53 µm à 180 µm. Cette poudre présente des vitesses de recristallisation lentes, comme le démontrent des pointes endothermiques et exothermiques sans chevauchement de leurs caractéristiques de calorimétrie par analyse différentielle à des cadences de balayage de l'ordre de 10 ~C à 20 ~C à la minute, ce qui permet d'obtenir des pièces frittées dont la densité est quasi-totale et dont les dimensions sont déformées au minimum.

Title: Assembly process including severing part of integral collapsible pump chamber
Inventor: STAHLEY ROBERT EDWARD
IPC: B05B11/00
Filed: 1995-09-29
Abstract: A collapsible pump chamber (60) is provided which includes several functional elements of a pump device (20). For example, the collapsible pump chamber (60) may be a bellows (60) which includes a functional element of an outlet valve (80), a functional element of a biasing feature, and a functional element of a spin chamber. Consequently, a functional element of all of the downstream functions are incorporated into the bellows (60). This can significantly reduce costs, due to reduce tooling, and assembly, for example. Since it can be desirable to separate these functions (e.g., to achieve more consistent spray quality), a process is described for severing functions from the multiple function collapsible pump chamber (60) during the assembly of the pump device (20). Dunnage means is also described for reducing the collapsed volume within the collapsible pump chamber.

Title: Steering control system for tracked vehicle
Inventor: STRAETKER JOHN GEORGE
IPC: B62D11/10
Filed: 1997-09-05
Abstract: A steering control system for a tracked vehicle includes an engine driven variable displacement steering pump which drives a hydraulic motor.  The motor drives a differential drive mechanism which drives left and right track drive wheels.  An electronic control unit, as a function of steering wheel position, vehicle speed, engine speed, forward/reverse vehicle direction and other parameters, generates a command signal which controls the swashplate of the steering pump.  The system operates so that, for a given position of the steering wheel, a turn curvature of the vehicle decreases as vehicle speed increases, wherein turn curvature is inversely proportional to a radius of turn.  This is accomplished by calculating a turn speed value equal to the vehicle speed multiplied by a ratio of a nominal engine speed divided by sensed engine speed, and by calculating the command signal equal to a steering gain value multiplied by a ratio of the turn speed value divided by a nominal vehicle speed value.
