Title: Improvements in and relating to Removable and Replaceable Thumbs and Fingers for Artificial Hands.
Inventor: RUDGE THOMAS
IPC: A61F2/58
Filed: 1917-08-30
Abstract: 120,933. Rudge, T. Aug. 30, 1917. Limbs, artificial.-The fingers and thumbs of a hand, adapted for movement either separately or as rigid combinations of two, three, or four fingers, are adapted for insertion in slots or recesses which are formed in the body of the hand and are provided with suitable operating- parts making connexion with others upon the inserted fingers; fingers of one shape may thus be replaced by those of another. The fingers themselves may be articulated. Fig. 3 shows a hand of which the thumb is detachable, and also the four fingers in one piece. The thumb is rocked about a pivot A<2> by means of an arm A<1> connected by a small spring C to a main spring B that is pushed outwards to flex the thumb by means of link-work F, G, H causing a rotation about a pivot C<1> as a rod F is pushed outwards by longitudinal movement of a rod X having a lever connexion with an operating-member in the wrist and arm, to which the hand is secured by a screw socket Z. The thumb, with its arm A<1>, is inserted into a slot S pressed in the body of the hand as shown in Fig. 4; similarly, a set of four fingers has a projection L for taking into a suitable recess in the body of the hand, together with a rooking-arm M, and a recess R through which a pivot pin N is passed. Fig. 5 shows an arrangement for flexing the fingers about joints W by means of cords Q, passing over pulleys V to rocking-arms upon the fingers, and working against restoring-springs U. These cords are operated by levers O hooking into stationary recesses P, Figs. 3 and 4, in the body of the hand, whereby the fingers are flexed at this joint simultaneously and as the result of their main movement derived from the central rod X at the wrist. Fig. 4 shows two rigid fingers V<2> in position upon a pivot pin Y<2>, held by a lock-nut in a recess Z<2>, and also in edge view the mechanisms T for operating the thumb and the fingers. A slot S<2> admits the pro. jecting part of the rigid first and second fingers (not shown) for movement about a pivot pin W<2>

A railway points operating mechanism in which a supporting member a is secured to adjacent sleepers b and carries a vertical spindle d turnable by a hand wheel e, a horizontal lever, or a detachable spanner to operate the points through a crank arm g has at least one tension spring i anchored at one end to the crank arm g and at the other end to the supporting member a and the force exerted is such that when the spindle is turned to move the points the torque required decreases. A rod k connecting the mechanism to the points may be attached to an extension of the crank arm g as shown in Fig. 2, intermediately on the crank arm g, or to a separate arm keyed' on the spindle d. In a modification, Figs. 4 and 5, (not shown) two or more springs i are anchored at their ends to crossmembers pivotally mounted on pins h and j. A one way switch mechanism is described in which the crank is formed as a bell crank, Fig. 6 (not shown).

Title: Overcurrent protection circuit for a voltage regulator

Filed: 1971-02-01
Abstract: 1379223 Automatic voltage control R C A CORPORATION 27 Jan 1972 [1 Feb 1971] 3604/71 Heading G3R An overcurrent protection circuit is provided in a voltage regulator. The voltage regulator comprises input terminals 11, 12 and, output terminals 13, 14, across which is connected load RL the voltage across which is detected by amplifier 30 which applies a signal to drive transistor Q 1  to regulate the load current through transistor Q 2 . A bridge network is provided having arms R 2 , R 3 , R L , R E1  in series with the base to emitter junction of transistor Q 2  which is stated to make the bridge more sensitive. A transistor Q 3  is connected across terminals 23, 13 of the bridge and is normally non-conducting. Between amplifier 30 and drive transistor Q 1  is a transistor Q 4  which is normally saturated by current through R 1  to the base 29 of transistor Q 4  and so is of low impedance. When an overcurrent flows through load RL, transistor Q 3  conducts and the current through base 29 of transistor Q 4  is diverted through transistor Q 3  so that transistor Q4 charges to offer a high impedance between amplifier 30 and drive transistor Q 1  to cut down the load current through transistor Q2.

Title: Method and apparatus for reshaping conduits
IPC: B29C53/82
Filed: 1955-02-08
Abstract: 768,753. Flexible mandrels. GOODYEAR TIRE & RUBBER CO. Feb. 8, 1955 [July 26, 1954], No. 3678/55. Class 83 (4). [Also in Group V] A flexible mandrel for supporting the walls of a conduit during a reshaping, e.g. bending, of the conduit comprises a length of resiliently extensible mesh structure, e.g. wire mesh in tubular form, adapted to be stretched longitudinally, to enter the conduit, and to support the conduit walls when the tension is released and the mandrel tends to return to its original diameter. The conduit to be reshaped may be formed of ductile metal such as lead and copper which may be deformed cold. The flexible mandrel comprises a tubular mesh 1 of braided resilient tapes 11, Fig. 7, or of braided flat bands 3, each band comprising tempered steel wires, 2, Fig. 3, placed side by side. At one end of the mandrel the bands are gathered into a lug-plate 4 and at the other end may simply be terminated to avoid unravelling or may be gathered to a plate 6. The cross-section of the mandrel corresponds to the cross-section of the conduit to be bent, e.g. a rectangular-sectioned mandrel for a rectangular-sectioned conduit, but the mandrel has an outside diameter when unstretched larger than the inside diameter of the conduit. The mandrel may have an expansible cover. In operation the mandrel is pulled by a cord 8 into a tube 9 to be bent, and the pull on the cord is then released to allow the mandrel to expand to support the tube 9. The tube is heated, then bent and then allowed to cool to regain its normal rigidity. The mandrel is then pulled from the tube by the cord 8 or by a cord attached to the other end of the mandrel. The cord 8 may be replaced by a flexible pushshaft extending through the mandrel and engaging the end thereof. Alternatively the mandrel may be prestressed before insertion in the tube and may be compressed axially while therein to increase its rigidity.

In wheel-holding chocks for aircraft, front and rear chocks for an undercarriage wheel 10 are secured upon a support, such as a channel-section girder 14, extending parallel to the longitudinal axis of the aircraft, the support being displaceable longitudinally in relation to a fixed base member 11 before the final positioning of the aircraft relative to ground equipment. In the embodiment illustrated one of the chocks 21 is made detachable from the support 14 to allow entry and release of the wheel 10 when the aircraft is brought into or taken out of position; provision being made for relative adjustment of front and rear chocks along the support to suit the diameter of the wheels. Rotation of threaded screw 17, in a clockwise direction forces inner girder 14, carrying a pair of chocks 21 and 22, to slide to the left. The chocks are spaced apart sufficiently for them to engage the front and rear of the tyre on the undercarriage wheel 10. 'The rear chock 22 is adjustable along girder 14 to allow for various tyre diameters. Provision is made for adjusting at least one of the base members 11 in a lateral direction to accommodate aircraft with wheels spaced at different track widths.
