Title: Improvements in Artificial Arms and Hands.
Inventor: THOMAS CHARLES WILLIAM
IPC: A61F2/58
Filed: 1916-07-20
Abstract: 103,610. Thomas, C. W. July 20, 1916. Limbs, artificial.-The fingers and thumb of an artificial hand are normally held distended by a spring, but may be closed to the gripping position by link-work mechanism operated through a cable by body harness. The fingers may be jointed only at the knuckles, or may have intermediate joints also, and the hand may be mounted so as to have a partial rotary movement when the arm is bent. In the form shown in Figs. 1 and 2, the four integral fingers 2 and the thumb 6 are moved about pivot pins 4, 7 by toggle-links 8, 10 and 9, 11 connected to a pin 12 working in a slotted plate 14 and connected to a cable 16, which passes over pulleys 17, 18 to shoulder harness. The spring 15 Fig. 5, each finger is independently mounted on a pivot pin 4 and comprises jointed sections 54, 55. The outer sections 54 are pivoted to links 57 formed with slots 58 engaging pins 59 on the inner segments 55 and connected to links 61 connected by cranks 63 to a shaft 64 adapted to be rocked by means of the cable 16. This construction normally holds the hand open. The hand is attached to the wrist portion of the artificial arm by a pin 20, which passes through a slotted plate 26 controlled by a spring 25 and adapted to engage a reduced neck 22 on the pin 20 so as to lock the hand in position. Automatic wrist-rotating mechanism operated on bending the arm comprises an arcuate rack 29 on the hand engaged by a toothed wheel or segment 30, which is partly rotated by a connecting-rod 34 actuated from a lug 35 on one of the upper arm members 36, Fig. 2a. The pin 31 on which the segment 30 oscillates may be moved in the slot 51, Fig. 2, so as to disengage the segment from the neck 29. The wrist may then be locked by a sliding bolt 52 engaging a recess 53 in the hand. The arm is held to the natural stump by a leather clasp 39 and padded straps 40. In a modified construction of the hand, causes the outer sections of the fingers to bend inwards relatively to the inner sections when the finger as a whole is pulled to the closed position. The thumb is actuated bv a link 67 attached to a short crank on the shaft 64, and the hand is normally held open by a spring 70. The hands are detachable from the arms and may be replaced by hooks such as those described in Specification 100,471. The hands may be made of wood or papier mÔchÚ, or, according to the Provisional Specification, of fibre. The Provisional Specification also describes a hand in which the wrist is locked by a pin which is caused to engage one of a series of holes in the wrist-plate by the action of axially displacing the toothed wheel. The locking-pin is held in place by a spring catch operable by a push-button on the wrist.

Title: Improvements in or relating to wireless transmitting or receiving sets
IPC: H03J5/10
Filed: 1940-06-14
Abstract: 543,576. Adjusting wireless apparatus. PHILIPS LAMPS, Ltd. June 14, 1940, No. 10377. Convention date, June 17, 1939. [Class 37] A device for tuning a wireless transmitter or receiver comprises three shafts (two only of which 21, 23 are shown) the angular positions of which determine the tuning of the apparatus. Each shaft has rigidly attached to it a driving cylinder 35 having a friction clutch connection 38, 39 with a corresponding gear wheel such as 22, 24, the three gear wheels meshing with a common gear wheel 28 and the whole gear assembly being driven through a gear 29 by a pinion 31 on a shaft 32. Adjustably mounted on the driving cylinders 35 are a series of rings 1 ... 9 corresponding to the number of predetermined wavelengths, all except ring 6 having a locking notch 37. Opposite each ring is a spring locking pawl 11-19 while centrally mounted on a spindle 27 is a selector drum having a series of rollers 111 ... 119 uniformly distributed along a helix, the arrangement being such that for each setting of knob 42 one spring pawl for each. driving cylinder is pressed against the corresponding ring by one of the selector rollers. If now shaft 32 is driven, either by crank 33 or by a motor, the cylinders are driven until the pawls enter the notches 37 thus arresting each cylinder in its selected adjusted position after which the clutches 38, 39 slip. In one position of knob 42, rollers press springs on to smooth rings of two of the cylinders such as 6 on cylinder 10 while on the third cylinder 20 a pawl engages a gear ring 41 rigidly coupled with gear 24. This locks the gear assembly entirely and allows independent adjustment of the shafts 21, 23 by hand using crank 33 on the upper ends of the shafts. In a modification, the driving cylinders are coaxially mounted on a common driving shaft to which each is frictionally coupled, and the selector rollers are mounted on a parallel axis.

Filed: 1972-03-07
Abstract: 1426172 Pipe couplings BRIDON Ltd 21 Feb 1973 [7 March 1972 24 Aug 1972] 10507/72 and 39480/72 Heading F2G In, e.g. a marine loading arm, a pipe flange 16 is clamped by means of an arm turning about a pivot 49, which is carried on a support 24. On extension of rams 25, the support 24 is swung about its pivot 23 to move arm 45 radially into the clamping position, in which pin 27 enters the short leg of L-shaped slot 28, to bring locking cam 48 into a wedging position. Thereafter, ram 34 is extended to effect clamping and, during a first phase of movement (47a-47b) turns arm 45 by direct lever action, without rotation of bell crank 37 about its pivot 44. During a second phase of movement (47b- 47c) cam surface 42 slides off nose 43, as bell crank 37 turns about its pivot, to increase the mechanical advantage of the ram 34 during this phase. In another form, rams 25 are omitted and a single ram (113, Figs. 3 and 3a, not shown) provides axial clamping as well as moving the clamping arm (117) radially. For cryogenic applications, space 20 may be filled with foamed polystyrene and end member 19 may be of P.T.F.E. For a smaller pipe flange 16, pivot 32 is transferred to holes 32a ar 32b.

Abstract: 466,373. Machines for making boxes. ROCHESTER FOLDING BOX CO. April 9, 1936, No. 10557. Convention date, Dec. 5, 1935. [Class 18] Relates to machines for making boxes having three side walls 6, Fig. 21, with end flaps 6<a>, the fourth side being formed by uniting by one or two adhesive strips 8, 9 the lateral extensions 7, 7<a> on the walls 6. Means are provided for causing the lateral extensions or ends 7, 7<a> to move on a supporting bar 92 into abutting relationship. Blanks 5 are fed through folding means by continuously operated means to the adhesive strip applying mechanism, and to position the extensions 7, 7<a> correctly, stops 99<a>, Fig. 19, are provided for temporarily stopping each blank in turn so that its rear edge can be engaged by a straightening or squaring member 100. The stops 99<a> are mounted upon a shaft 99 and are held against the front edge of each blank 5 by a torsion spring on the shaft 99. Upon continued movement of the member 100 the stops are displaced by the blank. The member 100 is pivotally mounted upon plates 101 carried by two reciprocating rods 103. The blanks 5 are ejected from a pile by a reciprocating member 57, Fig. 3, to feed roll 59, 59<a> and thence between driven rolls 38 and belts 40. The extension 7<a> of the blank is engaged by an inclined rod 79 to fold it relatively to the adjacent side 6. This side 6 and the end 7 are thereupon folded by two pair of inclined flexible rods 83, 84 and led to stops 99<a>. Before reaching the stops 99<a>, the blanks are speeded up to increase the distance between the blanks to facilitate the squaring operation. The folded-over ends 7, 7<a> leaving the second set 84 of folding rods are guided in spaced relationship upon the supporting bar or horn 92. The ends are pressed against the bar 92 by rolls, and as the section of the bar gradually changes to abutting relation. After the temporary stoppage by the stops 99<a>, each blank 5 is advanced by the member 100 to engage the trailing edge of the previous blank. The tape 8<a>, which constitutes the inner tape 8 in the finished box, is unwound from a spool, is led to a glue-applying roll and thence under the bar 92. The tape 9<a>, which is applied to the outside of the box, also passes over a g'ueapplying roll, and is applied to the blank by a pivoted member 159, Fig. 22, spring-pressed against the tape.

Patent GB-879320-A (GB)
Title: Multi-stage radial flow compressors
IPC: F04D17/12
Filed: 1958-04-02
Abstract: 879,320. Centrifugal compressors. SULZER FRERES S.A. April 2, 1958 [April 4, 1957], No. 10657/58. Class 110 (1). A multi-stage radial-flow compressor comprises a housing divided in an axial plane and diffuser inserts which surround each impeller and which are each followed by a deflecting bend and then by a separate insert which constitutes a return duct extending from the bend to the impeller inlet of the next stage, and between each diffuser insert and the preceding upstream return duct insert there projects a divided intermediate partition made as a structural unit with the housing halves, these partitions supporting the inserts and taking the pressure forces exerted in the axial direction by the working medium. Partitions 24, each preferably with an inside diameter smaller than the maximum diameter of the adjacent impeller, comprise semi-annular discs formed integrally with each half of the horizontally split casing 1, or welded to each half. Each interstage return passage is formed mainly by an insert 25 integral with guide blades 26 and ribs 28. Diffusion is provided by inserts 6 formed with blades 7 and each centred in a recess in the adjacent insert 25 and, it may be, helping to support the latter against the adjacent upstream partition 24. Each insert 25 is located radially and axially in a shouldered seat 29 in the adjacent downstream partition 24 and also lies against a part of the side surface of the partition near its outer diameter. Bores 33 and 34 equalize the pressures in chambers 40 and 41 with those prevailing in the corresponding parts of each return passage. Leakage around inserts 6 renders the pressure in each chamber 39 approximately equal to that at the exit from the corresponding diffuser. A pressure approximately equal to that at each impeller outlet is communicated by leakage to each chamber 37 and 38. The resultant forces on the stator parts provide an axial thrust towards the inlet end of the compressor, the partitions 24 being subjected to bending stresses and the inserts 6 and 25 being substantially free from bending stresses. The inserts 6 and 25 can therefore be made with relatively thin walls from grey (for example, nodular) cast iron or a cast light alloy, such as aluminium silicon alloy, whereas the casing 1, for reasons of strength, is of cast steel.

Patent GB-824301-A (GB)
Title: Protection of wooden structures
Inventor: WOOD OLIVER DERWENT
IPC: B05D7/08
Filed: 1956-04-10
Abstract: Wooden surfaces, e.g. boat hulls, are coated with a solution of a resorcinol-formaldehyde resin cement containing a hardening agent, e.g. paraformaldehyde, textile sheets of nylon filament yarn are laid adjacently upon the coated surface whilst the cement is still wet, the sheets are smoothed down, the cement is permitted to cure until a substantial peel strength is attained, and the sheets are then coated and impregnated with a film-forming, thermoplastic vinyl polymer resin in a volatile organic solvent.  The cement may be used in aqueous-alcoholic solution.  The vinyl resin may be a vinyl chloride-vinyl acetate copolymer or mixture of polymers.  More than one coat of vinyl polymer resin may be applied, and if more than one is applied, the first coat may contain hydroxyl radicals, e.g. a partially hydrolysed vinyl chloride-acetate copolymer, and a subsequent coat contain no such radicals.  Any substantial depressions in the surface to be coated may be filled with a stopping comprising wood flour and resorcinol-formaldehyde cement.  In the example, the textile sheets are tacked in position on a cement-coated boat hull by drawing pins, and the line of the keel is protected by a further strip of nylon fabric which overlaps on to the two sides of the keel and comes up and is smoothed down into close contact with the strips of nylon running up the hull.  The nylon is squeezed on to the resorcinol resin using a rubber squeegee, and the resin allowed to cure until a substantial peel strength is attained.  Strips of thin nylon tape are applied over the joints between the nylon strips and well doped with vinyl chloride-acetate copolymer resin solution. Five coatings of vinyl resin solution were then applied, the first being of the resin solution last referred to which is well brushed in to the nylon.  The second and third coats were of a similar but pigmented solution, and the last two of a similar but stronger solution free of pigment.  Known substances may be incorporated in at least the final coating to act as repellents for marine organisms, UV filters, and/or anti-fouling agents.ALSO:A stopping composition comprises a wood-flour, resorcinol-formaldehyde resin, aqueous-alcoholic cement, containing paraformaldehyde hardener.
