Abstract: ABSTRACT OF THE DISCLOSURE     The present invention proposes a process for manufacturing an object intended to be held in the hand and which comprises a body made from a plastic material reinforced inside by means of a frame and comprising at least one grasping zone having a hardness less than that of its other parts.  This process consists in plac-ing the frame in a mould comprising an injection aperture in the part of its cavity corresponding to the grasping zone of the object, clos-ing the mold, injecting into the cavity a definite amount of a com-pact plastic material, this amount being insufficient to completely fill the mould, then injecting an amount of expending plastic mater-ial to completely fill the cavity, the expanded plastic materiel, which while penetrating inside the volume of the non-solidified com-pact material, forces this latter to come into contact with the whole internal surface of the cavity of the mould and to cover the frame, and removing the object from the mould after cooling of the two plastic materials.

Abstract: ABSTRACT           A videodisc member is described having a uniform value of birefringence over the entire information storage surface of the disc.  This value of birefringence is the same at the inner information storage radius as at the outer information storage radius.  The preferable composition of the videodisc is either a specially prepared polymethylmethacrylate, referred to as PMMA, or a combination of PMMA and acrylic rubber.  The method of molding the improved videodisc member includes an extended drying time for said composition and increasing the melting temperature.  The increase in melt temperature provides a low and uniform value of birefringence.  The improved drying cycle eliminates splay marks, blisters and other surface imperfections as compared to manufacturer recommended drying times.

Abstract: ABSTRACT            A writing pen with writing point of any type, in the holder or grip portion of which is incorporated a movable-ribbon ready reference device readable through a window.  This device, pre-printed and capable of being written on by hand, is wound on a pair of spools which can be turned in both directions by means of a knob at the top end of the pen.  The knob forms a single whole with a tubular body on the inner surface of which is formed a helical toothing engaged with two toothed pinion gears, each of which is keyed idly to a flexible shaft rotating solidly with one of the spools on which the ribbon-type ready reference device is wound.  Forming a pair with each helical tooth pinion gear there is mounted, in an inverted position with respect to the other pair, a second butt pinion gear which is solid with the respective transmission shaft.  Each helical tooth pinion gear if free to travel a short longitudinal distance on its own shaft and then to engage or disengage the second butt gear pinion, with the result that each rotation direction of the knob will be matched by an axial translation of the idle pinion gears and the locking of one of them, with the freeing of the other, in the butt pinion gear solid with the transmission shaft, with consequent moving of the ribbon in the same direction.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved sensor having a ceramic element that undergoes a change in an electrical characteristic in response to a change in the partial pressure of oxygen in a mixture of gases to which the ceramic element is exposed.  Sensors of this type are used to detect the air/fuel ratio of mixtures supplied to internal combustion engines.  Prior art sensors are characterized by little change in their respective elec-trical characteristics at low operating temperatures.  A charge transfer meaterial, platinum or platinum/rhodium is applied to the ceramic element to facilitate or make possible the electron transfers required for sensor operation at low temperatures.  Platinum/rhodium alloy is the currently preferred charge transfer material. This alloy, which pre-ferably is 90% platinum and 10% rhodium, reduces the minimum temperature of operation for the sensor as taught herein, and it also substantially eliminates vaporization loss of the charge transfer material.

Title: Bearing carrier with integral lubricating sealing  features
Inventor: OWEN BRUCE R
IPC: F16C33/10
Filed: 1980-01-30
Granted: 1982-10-26
Abstract: ABSTRACT          A bearing carrier for high speed rotating machinery, such as a turbocharger, wherein lubricant is supplied under pressure and is drained by gravity. The primary feature is the forming of the bearing housing with a very large drain chamber which is obstructed only by a lubricant supply boss supporting a central housing portion in which a sleeve bearing is resiliantly mounted.  Lubricant exiting from the ends of the sleeve bearing is flung circumferentially away from the rotating components and drains naturally to a lower portion of the drain chamber where it flows through a drain passage port without re-entering the rotating components or piston ring seal area.  The drain port is so positioned with respect to the lubri-cant drain chamber and there is provided a dam around the seal-area at the axial end of the lubricant drain chamber whereby the machinery may be selectively positioned with the shaft horizontal, within 10° from the vertical or in intermediate positions and whereby there is effective draining of the lubricant from the machinery without flooding of the seals between the rotating components and the housing which would cause undue lubricant loss along the shaft.

Abstract: TITLE OF THE INVENTION     Pharmaceutical Composition Comprising Modified Polyriboinosinic-Polyribocytidylic Acid, for Induction of Interferon in Primates. ABSTRACT OF THE INVENTION     A complex of polyriboinosinic-polyribocytidylic acid (poly I:C) with poly-L-lysine hydrobromide ([lysine.HBr]n) having a defined molecular weight is prepared which is about 5-15 times as resistant to hydrolysis by pancreatic ribonuclease as the parent poly I:C.  A pharmaceutical solution, con-taining a relatively high concentration of the complex, prepared as described, induces significant antiviral levels of serum interferon in monkeys under conditions in which poly I:C itself induces little or no interferon.  An important feature of this invention is that the product is a soluble material requiring no special solubilizing agent, thereby facilitating the preparation of solutions having the desired concentration.  The product will hereinafter be designated as poly I:C/poly-L-lysine.

Abstract: ANTI-CRUSHING BAR ASSEMBLY FOR PIG FARROWING CRATES            ABSTRACT OF THE DISCLOSURE          When a sow lies down in a conventional pig farrowing crate, piglets are often crushed as they are unable to move out of the way fast enough.  This inven-tion consists of an inwardly curved bar pivoted by the outer ends thereof between a pair of supports extending between the comfort bar and the bar immediately there-above same.  It normally is retained in a horizontal position by means of stops and these bars prevent the sow from lying down quickly as they interfere.  With the bars in place, the sow has to manoeuver as she lies down in order to get her back under one bar and the other un-derneath the other bar.  This slows down the movement of the sow considerably thus enabling the piglets time to get out of the way.  When the sow stands up, the bars pivot upwardly giving her sufficient room to stand whereupon they return by gravity to the original horizontal posi-tion.
