Title: Improvements in or relating to artificial legs
IPC: A61F2/60
Filed: 1961-04-25
Abstract: 931,433. Artificial limbs. J. E. HANGER & CO. Ltd., and A. J. S. DADSON. May 9, 1962 [April 25, 1961], No. 14979/61. Class 81 (2). A pelvic socket, for use when the hip joint has been completely removed, is connected to a thigh member by a main pivot and a pivoted strut extends from the rear of the thigh member to the base of the socket. The thigh member 2 is connected to the pelvic socket 1 by a main pivot 3 and the strut 5 extends from a pivot 8, located within the bottom wall of the socket, to a pivot 12 in the thigh. The strut comprises a rod 5, articulated at 30, sliding telescopically within a cylinder 4 so that as the leg is moved from the fully extended position I to the fully flexed position III the rod is drawn out of the cylinder and bends, at the pivot 30 and thus, in the sitting position, the strut mechanism does not protrude beyond the boundaries of the thigh and socket. An apertured, spring-loaded catch 18 is positioned around the rod 5 between a collar 16 and an adjustable stop member 9 and normally limits the relative movement between the rod 5 and cylinder 6 to the distance between these two stops. This allows sufficient angular movement of the thigh for normal walking, but, when the catch plate 18 is disengaged by an externally actuated lever 42, the rod may be completely retracted to allow the user to sit. Thereafter the catch is automatically re-engaged when the user again stands. Adjustment of the free movement for walking is obtained by manually screwing the stop 9 up or down the rod 5 while the setting for the final, extended position of the leg is determined by a stop member 13 screwed on the cylinder 6 and carrying a resilient abutment 15.

Abstract: 1,110,680. Ratchet gearing. G. M. PFAFF A.G. 3 April, 1967 [6 April, 1966], No. 16118/67. Heading F2Q. [Also in Division D1] A shaft carrying one or more control cams is turned into consecutive angular operating positions by means comprising a ratchet mounted on said shaft, a pawl operated towards and away from said ratchet over a stroke normally insufficient to effect actuation of the ratchet, and manually-operable means for displacing the ratchet by a predetermined angle so as to enable actuation and rotation of the ratchet by the pawl from one to the next operating position of the shaft. A shaft 27 in a zig-zag sewing machine carries a ratchet 29 and cams 16, 26, 28 controlling the stitch width, stitch position and work feed respectively. A lever 45 carries a roller 47 biased by a spring 49 against a cam 46 on a shaft 4 for oscillating lever 45 once at each revolution of shaft 4 when the needle is wholly above the work. A pawl 44, pivoted to lever 45, is biased by a spring 48 against ratchet 29, the stroke of pawl 44 being less than the pitch of the teeth 42 of ratchet 29. A pawl 50, pivoted to one arm of a lever 51, is biased by a spring 58 against ratchet 29. The other arm of lever 51 carries a handle 52 and also carries a lug 53 biased by a spring 57 against a fixed abutment 55. For turning shaft 27 from one operating control position to the next one, handle 52 is actuated to engage lug 53 with a fixed abutment 54, and thereby to turn ratchet 29 just sufficiently to enable pawl 44 to engage a tooth 42 on its next forward movement.

Title: Method of and apparatus for modifying the position of the stroke movement of a ram in gear tooth profile grinding machines
Inventor: BRANDNER GERHARD
IPC: B23F23/12
Filed: 1967-04-04
Abstract: 1,169,261. Gear-grinding. INSTITUT FUR WERKZEUGMASCHINEN. 4 April, 1967, No. 15336/67. Heading B3K. In a machine for grinding helical gears, the stroke position of the reciprocating wheel 6 is modified in dependence on the rotational or translational component of the generating movement. The rack-toothed wheel 6 is reciprocated by a fluid pressure ram 101 mounted on an angularlyadjustable head 3, the fluid being supplied by an infinitely-variable-speed, reversible pump 13. The gear Z is carried on a rotatable table 9 on a saddle 8. As the saddle is moved laterally in the generating movement, its position is gauged by a digital device 151, 152. An analogue voltage is fed to a computer 18 together with an analogue voltage from a device 161, 162 which gauges the position of the grinding head 4. Potentiometers 181, 182, 183 are employed to set in the stroke length of the wheel 6, and the tooth width and the helix angle of the gear. The computer calculates the upper reversal point of the head 4 according to the position of the saddle 8. The lower reversal points are determined by the stroke length. Control is exercised through an electro-hydraulic system 22 and the pump 13. In a modification, the head 4 is reciprocated pneumatically under the control of electromagnetically actuated reversing valves. The position of the stroke path of the wheel is gauged by fixed dogs 29, 31, Fig. 5, co-operating with a switch 31 adjusted by a screw 33. The position of the saddle 8 is indicated by a feeler 36 engaging an adjustably inclined bar 37. In another modification, an hydraulic pump is reversed under the control of a timer and an hydraulic proportioning device adjusts the position of the stroke path of the ram piston within its cylinder. In a further modification, the head is reciprocated by a crank mechanism, the point of attachment of which to the ram is adjusted by a screwed shaft according to the angular position of the work. One component of the generating motion may be effected by the wheel.

Abstract: 583,852. Road &c. rollers; agricultural implements. ALEXANDER, T. F. N. Sept. 20, 1943, No. 15400. [Class 6 (i)] [Also in Group X] For aeration, or to receive material such as asphalte tar, bitumen macadam or concrete in the construction of a landing ground for aircraft &c. or to render road surfaces non- skidding, or to receive seeds, fertilizers and/or humus, holes are made in the ground by a roller having a number of series of circumferential holes, each series being arranged in a common plane perpendicular to the roller axis, an inwardly spring-urged tine or prong in each hole, and a set of internally disposed stepped cams which project the tines &c. one after another and act upon them positively until the hole produced by each is complete, after which they are abruptly withdrawn by the springs. As shown a roller is built up of a number of flanged disks 1 with a central recessed boss 4, the flange and bars having radially aligned holes slidably receiving prongs 6 which are pressed inwardly by springs 7 ; stationary cams 5 are carried by the axle 2, whereby as the roller advances, the prongs are projected to form substantially non-tapering holes while the weight of the roller prevents tearing of the ground, the springs 7 afterwards effecting abrupt withdrawal of the prongs. The axle may project to receive traction wheels for transport, or it may be mounted in a draw bar chassis 9 provided with traction wheels 10 which may be raised or lowered by a screw 11. The axle may be adjustable through say 180 degrees and then locked so that the prongs when ejected are clear of the ground. The roller may be followed by a material-supplying magazine, such as a hopper with a slide valve or perforated drum feeding device, and by a pegged roller to press down the filling.

Abstract: 291,793. Lorenz Akt.-Ges., C. June 10, 1927, [Convention date]. Cards, punching.-In the manufacture of jacquard cards, the selection of the mechanical stamps is effected by photo-electric cells controlled by ligh trays reflected from the original pattern or picture. This may be carried on a cylinder 1 driven by a worm wheel 2 and worm 3, so that a ray of light may be made to traverse in sequence all the fields of one row of the pattern \\:c. After reflection, the light controls the current impulses in a photo-electric cell 6 in conjunction with an amplifying arrangement 7 having a relay 8 controlling a battery 9 and polarized relays 15. These correspond in number to one row of the pattern and they are operated in sequence by means of a number of distributing contacts 12 on an insulated disc on the worm wheel. The periphery of the disc 10 carries an incomplete ring 11 and the contacts 12 engage in succession with respective contact springs 14, so that under the control of the photo-electric cell 6 the polarized relays 15 are operated in sequence according to one row of the pattern. The relays then control the stamping of the card, which may be effected by a device controlled by the worm wheel. Afterwards a reversing contact 13 causes a current impulse to be sent from ' a counter battery 16 to the relays to return them to normal position, and the ray of light is directed to the next row of the pattern, by moving the cylinder or the light laterally. A double row of relays 15 may be used to give a continuous' operation. A contact drum may be used instead of the contact disc. Holes may be punched to correspond with a multitone pattern, light filters being used to produce preliminary cards corresponding to the different colours or tones of the pattern.
