Title: Improvements in dental handpieces
IPC: A61C1/18
Filed: 1965-04-13
Abstract: 1,046,683. Dental engine handpieces. SOC. ANON. MICRO-MEGA. April 13, 1965 [Feb. 20, 1965], No. 15639/65. Heading A5R. In a dental handpiece comprising a housing which has a drive element mounted at one end and means for fixing a dental tool at the other end, and which accommodates a mechanism for transmitting the drive to the tool, there are provided in the housing a feed circuit conveying compressed air to the tool-carrying end of the handpiece to create in this region of the housing an excess pressure to prevent the introduction of impurities, and means for preventing the compressed air from interfering with the lubrication of the movable elements in the housing. The drive element may comprise a wrist, the compressed air source being located outside the handpiece. As shown, one end of the housing 1 is connected to the casing 2 of the counter angle which carries a dental tool (not shown). Mounted in an extension of the other end of the housing is a miniature electric motor 3, the shaft 4 of which is coupled to shaft 5 (rotating in bearings 12 and 13) of the handpiece which drives, by means of pinions 7 and 8, shaft 6 (rotating in bearings 14 and 15) of the counter angle which drives the dental tool by means of gears 10 and 11. Compressed air, the source of which is cooling air for the motor, enters the housing and passes via ball coupling 18 to the head of the handpiece, generally following the arrowed path. Excess air may escape through nozzle 16 and orifice 17 separating the motor from the handpiece and through aperture 19 in which a rod may be inserted for removal of the dental tool. Air also escapes through the gaps separating the sleeve 9 holding the tool from the bearing 20 of the head casing 21 and thus prevents introduction of impurities into the handpiece. The means to prevent interference with lubrication may comprise grooves 22 in the body portion 23, these grooves retaining the lubricant by capillary action against the flow of compressed air. Whilst being exemplified with regard to a counter-angle handpiece, the invention is stated to be applicable to all types of handpieces.

Title: X-ray contrast medium
IPC: A61K47/24
Filed: 1966-04-07
Abstract: An autosterile X-ray contrast medium, especially for use in lymphography in the form of a stable substantially anhydrous emulsion, comprises (1) an iodinated vegetable oil or an iodinated lower alkyl ester of a vegetable oil wherein the alkyl group contains from 1-3 carbon atoms, (2) glycerol, and (3) an ethanol-soluble lecithin as emulsifier.  Component (1) is preferably iodinated poppy seed oil, sesame oil or rape seed oil or iodinated ethyl ester of poppy seed oil and (3) may be soy bean or egg lecithin.  The weight proportions of the components may be (1) 20-65%, (2) 30-75% and (3) 3-10%.  The medium may also include oil-soluble chlorophyll.  The medium is prepared by dispersing the lecithin in the glycerol under substantially anhydrous conditions and then admixing this with the iodinated vegetable oil (or lower alkyl ester thereof); on standing for at least 3 days at room temperature the emulsion is sterile.  The medium is diluted with sterile water, e.g. an isotonic aqueous solution of glucose or Na Cl, to give an injectable composition, the water content preferably being from 15-60% by wt. of the final aqueous emulsion.

The X-Y movement of the holders 6, 7 is provided by sliding on rods 1, 2 and 3 or 4. Each holder comprises two transparent plates 6a, 7a, 6b, 7b, the top plates being hinged to permit insertion of microfilm between each pair of plates. A slider 19 having guide pins 17, 18 has stops 20, 21 which when abutted and moved by the holders 6, 7 respectively cause relative movement of the optical path 15 and the lenses 8, 9. This change over only occurs when one holder is removed from the path 15 and the other substituted for it. As shown each holder and lens is separated by a distance a from the other holder and lens. In Fig.1 the optical path is fixed and movement of slider 19 causes stops 22, 23 to switch over the lenses 8, 9, suspended by arm 11 about pivot rod 10. A diaphragm 14 is provided. In Fig.2 the lenses 8, 9 are fixed and slider 30 carrying lamp 27, reflector 28, condenser 29 and mirror 26 is moved by reversing lever 25 connected to the slider 19. The mirror 26 acts as the diaphragm in this construction.

[Also in Division F2] In a rotary screw pump as described in Specification 1,033,872, the pump includes a drive-shaft 26, Fig. 1, passing through a rotary seal at the suction end of the pump and connected by a universal joint 30 to one end of an intermediate shaft 24 which is connected at its other end by a similar joint to the rotor 20. The seal comprises a guide ring 54 having clearance with respect to the shaft 26 and an inner end face ground perpendicular to the shaft axis which abuts a carbon ring 64 co-operable with a spring-loaded O-ring 64a which rotates with the shaft. The seal is completed by a conventional sealing sleeve 60 inserted in a recess 54b in the guide ring to shield the bearing 52. A space between the sleeve 60 and the recess communicates with atmosphere to permit leakage when the pump is inoperative. Each universal joint 30 includes a ball-joint receiving exclusively axially directed forces acting on the rotor and a cross-pin exclusively transmitting torque. The intermediate shaft 24 is ball-ended with hemispherical surfaces 28, Fig. 4 (not shown) seating on complementary seats 42 in the rotor 20 (or drive shaft head 26b). Pins 36 perpendicularly disposed with respect to each other and to the shaft axis pass with clearance through bores 34 in the ball-ends. The bores 34 are tapered partly in the planes common with the shaft axis and partly in planes perpendicular thereto to permit conical oscillatory movement of the shaft. The tapers are arranged so that torque is transmitted by line contact between the pins and the bases. Coned nuts 38 secure the pins 36 to the rotor 20 and drive shaft head 26b.

[Class 135] [Also in Groups VIII and XIII] In a gas-iron wherein gas is supplied to a combustion chamber 1b from an inlet connection 19 through a thermostatically-controlled valve 5, 6, hollow handle 2 of Venturi form, and curved pipe 27, the thermostat comprises a tube 3 of high coefficient of expansion and a rod 4 of low coefficient. The rear end of the tube is secured to a spigot 7<1> on the valve chest 7 slidably mounted in an aperture 7<2> in the rear wall of the chamber 1b, and the front end of the tube is slidably mounted in an aperture 31 in the front wall. The valve-head 5 is spring biassed to closing position and is provided with a socketed stem 12 which receives one end of the rod 4 which is slidably mounted in the valve seat 6. The other end of the rod is carried in a sleeve 9 and its position therein is adjusted initially by a screw 8 which is then locked in the sleeve by a pinching screw 81 which is normally inaccessible. The sleeve is screwthreaded into the tube 3 and is rotatable therein by an amount slightly less than one revolution so as to vary the operative temperature of the thermostat, the sleeve being provided with a head 9<1> having a slot 9<2>. The valve seat 6 is provided with a ring of small apertures 18 which register with a circular groove 17 in the face of the valve head 5 with which groove a byepass aperture 22 communicates. Gas reaches the apertures 18 when the valve is off its seat partly by passing the periphery of the valve and partly through radial ports 20 and an axial bore 21 in the valve stem. As the rod 4 shortens relatively to the tube 3 as the iron heats up so the valve is progressively closed by the spring 14. Specification 360,555 is referred to in the Provisional Specification.
