Title: Improvements in or relating to artificial limbs
IPC: A61F2/58
Filed: 1923-04-16
Abstract: 216,640. Wilson, B., and Adams, A. C. April 16, 1923. Limbs, artificial. - The chain &c. 1 used for raising and lowering the forearm 11 of an artificial arm is secured to a cam 2 pivoted at the rear of the forearm, the chain being also secured to the forearm at a point 13 below the pivot pin 12, a locking pin 17 being provided to hold the arm in its adjusted position. The pin 17 engages in holes in a disc 15 formed on the forearm and is operated by a spring-pressed lever 21 to which an actuating chain 24 is attached. The chain 24 is also secured to a cam 26 pivoted at 27. A catch 28 which frictionally engages the cam 26 is provided to hold the pin 17 in the raised position. A bucket 42 is attached to the forearm 11 by a tubular member 37 which slides over an extension 31 of the member 11 and within a sleeve 32 attached to the member 11, a spring-pressed pin 33 engaging in a groove 36 in the member 37. Rotation of the member 37 is prevented by a slot 40 at its upper end in which pins 41 engage. Fig. 6 shows the wrist end of the bucket 42 which carries a removable member 51 to which various fitments can be screwed. The member 51 is held in a sleeve 45 by means of a spring-pressed pin 48 and is prevented from rotating by a pin 53 in the sleeve 45 which engages slots in the upper end of the member 51. When the bucket 42 is removed from the forearm 11 the member 51 can be attached to the extension 31 in place of the member 37.

Abstract: 1412622 Dental handpieces J C V MITCHELL 7 June 1973 [8 March 1972 2 May 1972 11 July 1972 4 Dec 1972] 10701/72 20266/72 32278/72 and 55912/72 Heading A5R Handpiece: A dental handpiece 2, Fig. 1, comprises an elongate body 32, Fig. 2, connected via a neck 34 to a head 36 housing a rotary chuck for a dental bur 50, the body housing an electric lamp 78 adjacent the neck 34 which is transparent and has an external surface which reflects internally the light travelling in it, a portion 62 of the surface having reduced reflectance so that light issues from it towards the head 36, the neck 34 also encapsulating at least one drive conduit for the chuck. The body 32 also houses a member 42 reciprocable parallel to the axis of the handpiece, the neck 34 housing a conduit 46 having a curved portion 48 terminating adjacent the head 36 and housing a probe (54), Fig. 5, (not shown) connected to the reciprocable member 42 and having a hard tip (58), the probe (54) being reciprocable between a retracted position within the conduit and a projected position beyond the bur 50. Control Unit: A motor-driven handpiece 4 and the handpiece 2 which is turbine-driven are controlled from a unit 6 which has switches 22, 24, 26, 28, 30 for various modes of operation of the handpieces 2, 4. When either handpiece 2, 4 is disengaged from a respective rest 12, a microswitch 14 is closed to cause the handpiece to be supplied with electricity, air and water. The speed of the bur 50 is controlled from a boot-operated switch 8. Handpiece Body: The reciprocable member 42 consists of a piston in a cylindrical housing 40 which together form a pneumatic ram 38 whose position is controlled by air from tubes 44. The conduit 46 extends from the housing 40 through the body 32. The lamp 78 is cooled by air from an exhaust conduit (65), Fig. 3 (not shown) of the turbine or from another conduit 84. The neck 34 houses the conduit 46 and a conduit (72) for water which is ejected towards the bur 50. A flexible sleeve 98 covers the body 32 and the neck 34. In an alternative embodiment, the bur 50 is driven by a micromotor (88), Fig. 4, (not shown) via a flexible drive cable. Probe: The probe (52) is formed from a cylindrical wire of stainless steel, and has a head portion (54) integral with a tail portion (56) of reduced diameter. The tail (56) is annealed so that it is softer than the head (54) so that the probe (52) can slide easily in the conduit 46. Air from the housing 40 is passed through the conduit 46 and emerges near the end of the conduit (72) and atomises the water issuing therefrom.

Abstract: 1298393 Reservoir pens C M DI CARLO 6 March 1970 [6 March 1969] 10974/70 Head ing B6P Between the upper and lower barrel portions of a stylographic pen there is a control member 41 having a slightly smaller diameter than that of the inner barrel, with either the barrel or the control member (as illustrated) having a helical thread on the surface to receive and retain a film of ink between the crests of the threads and the adjacent cylindrical surface. The roots of the thread form a venting passage between the ink containing lower portion 12 of the barrel and the upper portion 11. A stem 25 carries both the clearing wire 37, and the control member 41. The upper end of the stem 25 is slidably mounted in a bushing 21 press fitted into the rear of the barrel. Threaded to the rear end of the stem 25 is a threaded button 26 co-operating with screw-threads in the rear of the bushing. When the button 26 is screwed home, Fig. 1, a sealing washer 29 hermetically seals the rear of the barrel. When the button 26 is unscrewed (Fig. 2), compression spring 30 biases the stem 25 rearwardly, thereby withdrawing the clearing wire 37 into the tubular nib 15. Reciprocating the button 26 against the bias of spring 30 clears out the dried ink from the tubular nib. As an alternative (Fig. 7), the clearing wire has helical grooves in its outer surface to permit free flow of ink to the tubular nib point and the edges of the grooves assist in the clearing of dried ink. To fill the barrel with ink, the bushing 21 and stem 25 are removed and a plunger (17, Fig. 3) inserted into the barrel.

[Class 38 (iv)] A spring system for a regulator of the carbon pile type comprises a main spring arrangement of variable rate and an auxiliary spring of substaritially constant low rate in parallel therewith. As shown in Fig. 4, a double-vee spring W and a coil spring C press against a bridge piece B which is in contact with rods R attached to an armature M. The spring C is adjustable by a screw A and passes through a hole in the spring W so as to press freely on the bridge piece B. The double-vee. spring W consists of two 'oppositely bowed blades or plates which may be connected together at one end by a rivet, the inner blade bearing against the bridge piece B and the outer blade resting against abutment screws (not shown) by which the initial loading of the springs is adjusted for maximum compression of the carbon pile (not shown) to which pressure is transmitted by rods R, an armature M, and a rod N. In a modification the initial adjustment of the double-vee spring is effected by a central screw and two coil springs are arranged one on each side of this screw. In another modification, Fig. 12, a laminated magnet T is formed with poles O and is energized by a coil Q. An armature M<SP>1</SP> is pivoted at 1 and has an extension M<SP>2</SP> carrying a ring pivoted at 5 which presses on the carbon pile 2.
