Title: Handpieces for dental surgery and the like
IPC: A61C1/14
Filed: 1972-04-12
Abstract: 1344201 Dental hand piece MICRO-MEGA SA 12 April 1972 [13 April 1971 2 March 1972] 16828/72 Heading A5R A dental handpiece comprises a body 2 having a shaft 6 therein, a chuck secured to an end of the shaft and including an inner component 8 having radially moveable jaws 17, 18 and an outer component 7 which is moved relative to the inner component by a rotatable actuating member 19 which is accessible through an opening 21 in the body when a cover 22 in the form of a sleeve is moved to a position (Fig. 5, not shown) where it cooperates with a locking member 25 to prevent rotation of the shaft or one of the components of the chuck. As the cover 22 is slid towards the rear of the handpiece the rod 25 is forced inwards causing its end 24 to engage in toothing 23 on the shaft. The actuating member 19 is then rotated and through the screw thread 10 causes frusto-conical faces 13, 14 on the shaft 6 and sleeve 7 to move together or apart. The inner member 8 consists of four members which have frusto-conically shaped faces on their jaws 17, 18 whereby faces 13, 14 approach one another the jaws grip a tool inserted into the opening 16 of the chuck. In a modification (Fig. 6, not shown) the inner component (108) is fitted to end of the shaft (106) by a screw thread and is prevented from rotating relative to the axially fixed outer component (107) by a stop (112). As the cover (122) is opened a spring (117) forces a pin (113) into toothing (110a) on the outer component (107) to prevent its rotation. Rotation of the actuating member (119) rotates the shaft within the outer component and thus moves the inner component axially relative to the outer component causing the faces (111, 109) to slide over one another to grip or release a tool.

Filed: 1939-06-12
Abstract: 530,059. Draught regulators. RECOMATIC SOC. ANON. June 12, 1939, Nos. 17129 and 17130. Convention dates, June 15, 1938, and May 22, 1939. [Class 51 (i)] A draught regulator for combustion apparatus comprises a rotatable air inlet damper arranged in the wall of a flue and adapted to open under the influence of a depression in the flue, the amount of opening being controlled by an abutment member actuated by a heat sensitive element arranged within the flue. As shown in Fig. 2, the air inlet aperture 4 in the flue 1 is controlled by a damper 5 mounted on a vertical spindle 6 provided with a double-armed lever one arm 10 of which is acted on by a spring 12, the tension of which may be adjusted by a screw 13, serving to maintain the damper closed. The other arm of the lever 11 bears against a transverse member 22 which is connected by rods 19, 17 to a heat sensitive member 15 arranged within the flue 1. Flexing of the heat sensitive member 15 by variations in the temperature of 'the flue gases varies the position of the member 22 and permits the damper 5 to open more or less to admit air to the flue to check the draught: Instead of one damper only, two may be employed each controlled by the heat sensitive member. In the modification shown in Fig. 4, the damper 33 controlling the air inlet to the flue 25 is mounted on a spindle slightly inclined to the vertical so that it tends to close by gravity and is provided with an arm 55 which bears against an adjustable member 52 connected to a spring 53 secured to a fixed frame. The member 52 is connected by a rod 51 to a heatsensitive member 47 arranged in the flue and carried by sliding rods 42 which may be adjusted by a screw 56. Increase of temperature in the flue causes the member 52 to move away from the arm 55 to allow the damper 33 to open and admit air to the flue.

Abstract: 662,701. Wheel scrapers. CARLTON, W. C. June 30 1949, No. 17335/49. Addition to 613.666 and 653,989. Class 108(ii) The tyre scraper according to the parent Specification which includes an extractor mounted upon a body of rubber or like resilient material, is modified by making such rubber or the like mounting of such a cross section, e.g. a flat strip, that it is more easily bendable in one direction than another. As shown in Fig. 1, the extractor comprises a blade portion B<SP>2</SP>, which may be a round steel bar, half round, chamfered or serrated, which is attached to a flexible connector C<SP>2</SP> rigidly fixed to the mounting bracket A<SP>2</SP>. The connector is of flat or oval cross-section, or may be built up from .a number of parallel members of circular cross section, so that it is more flexible in one direction. The connector C<SP>2</SP> is preferably of polyvinyl chloride, but may be of rubber or plastic material which may be reinforced with fabric or woven wire. If of rubber, it may be bonded to its fastening clips. Fig. 6 shows two further modifications attached to the vehicle and applied to tyres. On the right-hand side the serrated extractor B<SP>5</SP> is attached to the flexible connector C' by a clip H<SP>1</SP> which is slightly arcuate. The fixing bracket A<SP>3</SP> may also be slightly arcuate. The connector C" thereby takes on an arcuate cross section and is comparatively stiff until it is bent back by a foreign body in the tyre whereupon it flattens out and is then comparatively flexible. On the left-hand side of Fig. 6 the connector C<SP>5</SP> is divided into two or more sections, each carrying an extractor B<SP>4</SP>; with this arrangement the configuration of the tyre tread, which changes with wear, is more closely followed by the extractor members. The examples shown in Fig. 6 when fitted to commercial vehicles may also act as mudguards. In a further modification, Fig. 4 (not shown), the connector may be of extruded form and its ends may fit into complementary extended brass fixing members. Each of the above arrangements may be subjected to a damping action as described in Specification 622,361.

Title: Treatment of hydrocarbons
Inventor: EASTMAN DUBOIS
IPC: C01B3/22
Filed: 1959-05-22
Abstract: The hydrocracking of liquid hydrocarbons is effected by passing a mixture of hydrogen and the hydrocarbon through a tubular reaction vessel at 800-1500 DEG F., and at least 500 p.s.i.g. with a turbulence level of at least 25, the turbulence level being defined as the ratio of the average apparent viscosity to the molecular or kinematic viscosity.  Both gas and liquid may be recovered as product, part of the gas being recycled if desired. Unrequired product may be subjected to partial combustion to form a gas containing hydrogen which, if desired after reaction with steam to form more hydrogen and carbon dioxide which is washed out, is recycled for use as the hydrogen reactant and/or combined with gaseous product for use as a fuel or town gas.  Gasoline product is recovered for use as motor fuel.  The liquid hydrocarbon may be vacuum residium, kerosene, gas oil (straight run or cracked), whole crude, shale oil, tar sand oil, straight run gasoline or liquids obtained by destructive distillation of coal.  The oil may be in the liquid and/or vapour phase and is contacted with 1,000-100,000 SCF of gas per barrel, the gas containing at least 25% by volume of hydrogen, for 20-200 seconds. Partial combustion of products is effected at 2,200-3,200 DEG F. using sufficient oxygen to convert 90-99.5% of carbon to carbon oxides, e.g. 1.6-2.0 pound mols of oxygen per million Btu gross heating value of the feed.  Steam may also be added.  The subsequent reaction with steam is effected with a 4-5:1 water to carbon monoxide ratio over an iron oxide catalyst.
