Abstract: A soft and flexible device with a gripping portion for releasably engaging, stabilizing and aligning the portion of a naso-gastric tube where it exits the nose adjacent a patient's upper lip; the device is releasably secured on the patient's head by an adjustable harness that encircles the head.

Abstract: The method of manufacturing such drill head by embedding the shank portions of hard, wear-resistant cutting elements in a mold containing metal powder, cold isostatically compacting the powder and shank portions to form the core part of the drill head, and hot isostatically compressing this core part to completely densify same.

Abstract: This invention is a retention suture bridge device for positioning and securing the exposed portion of a retention suture above and out of contact with an incision closure while the retention suture remains tied. This new device is formed of an arch part with end parts thereof aligned along a longitudinal axis, a series of holes along the arch through which the ends of a retention suture may be extended, and a generally round foot part secured to each end part and pivotal on the end part about the longitudinal axis.

Abstract: An installation for storing and recovering heat energy having a principal application in solar power stations.The heat produced is stored in a storage reservoir when the converted energy demanded is less than the heat energy produced, and recovered in the opposite case, these operations being carried out entirely automatically. The heat transfers are effected through a thermofluid able to flow by streaming over containers of any shape, enclosing a heat storage substance, and disposed loosely or methodically in said storage reservoir.

Abstract: In a multi-part plastic cage having a comb part with a plurality of axially extending webs adapted to engage a cover part, the cover part has recesses for receiving the ends of the webs, to absorb radial forces. The parts are joined by pins extending from one of the elements into recesses in the other, adapted to be joined by ultrasonic welding at positions spaced from the web ends, so that the pins are subject only to axial loading.

Abstract: A clutch release bearing for attachment to a diaphragm spring declutching member, the bearing comprising an outer race and an inner race, an annular series of rolling elements which roll on the raceway of each race to transmit thrust therebetween, one bearing race having a radially extending shoulder for engagement with a diaphragm spring declutching member and a sleeve attached to that race for rotation therewith about the axis of the clutch, which sleeve extends axially for connection with the side of the diaphragm spring declutching member remote from the bearing, the other bearing race having a radially extending shoulder on which a clutch operating member can act to move the bearing axially to engage and disengage the clutch.

Abstract: An apparatus for injecting a radiopaque dye into an artery of a patient during intraoperative arteriography, where the plunger of a syringe containing the injectate is driven by a separate but connected hydraulic sub-system operated by a surgeon who is at a location that is remote and safe from the radiation, and where the hydraulic sub-system provides for the surgeon, the feel and control of a conventional syringe operated manually in the immediate vicinity of the patient.

Abstract: A laceless boxing headguard having a front panel, side panels including ear protectors extending from each side of the front panel, a wide band of elastic extending across the rear of the headguard between and connecting the rear edges of the side panels, and inelastic adjustable belt also extending between and connecting the rear edges of the side panels, and an adjustable and relatively inelastic web spanning the top of the headguard between the front panel and rear band and laterally between the side panels.

Abstract: A pocket filter in the form of a filtering block is provided with an assembly of channels open at one end to receive gas from which dust is to be removed, and is interleaved with the channels of another assembly open towards the other end and delivering the gas from which the dust has been removed. These channels have a generally square-shaped cross-section, and are connected to each other, for example by stitching lines, along their edges. During operation, the initial shape provided for the cross-section of the channels of the two above mentioned assemblies is maintained by tensioning these two assemblies with tensioners or the like, on which are fixed the edges of the outer channels of the filtering block.

Abstract: A drill bit for conical cutting elements, each secured to a bit segment by an annular locking bearing which is fed by a first lubrication system which directs high pressure lubricant through the bit segment and locking bearing to space external of the drill bit at lower atmospheric pressure; each cutting element is further coupled to the bit segment by a second annular bearing radially inward of the locking bearing and lubricated by a second lubrication system independent of the first; the second lubrication system defines a closed space containing lubricant and the second bearing with one boundary of this space being a flexible wall whose outside surface is exposed to the atmospheric pressure external of the drill, the wall being deflectable to equalize the pressure of the second lubrication system with the atmospheric pressure.

Abstract: A camera having a zoom function includes a camera body, a lens system, a grip for supporting the camera by hand, a photo-operation button which is manually depressible, a photo-operation member which is displaceable by the photo-operation button in a linear direction for operating the camera and is further displaceable in a second direction approximately perpendicular to the first displacement for zoom-up or zoom-down operation, and an additional operation member for varying the zooming speed in response to the amount of displacement of the photo-operation member.

Abstract: A linear-motion ball bearing has an outer sleeve and a cylindrical cage within the sleeve, with endless raceways defined by the sleeve and cage, and balls substantially filling the raceways; the cage is formed of axially-extending sections, with a gap defined between the pair of adjacent edges of each two adjacent sections, and a projection extending circumferentially from one of each pair of edges into a recess of an adjacent edge.

Abstract: An electric hair dryer having a generally spherical outer housing with an elongated handle extending in one direction, a generally spherical inner housing with an air discharge duct, the inner housing mounted in the outer housing in a first position with the duct extending in a direction opposite the handle, the inner housing being pivotable to a second position where the duct extends transversely of the handle, and a power section mounted within and pivotable with the inner housing and including an electric motor, a fan driven by the motor, and a cylindrical electric heater positioned such that air flows inwardly through its cylinder walls and then axially through the cylinder to the discharge duct.
