IPC: F16C1/22
Filed: 1935-01-31
Abstract: 451,225. Bowden mechanism. BARBER, W. E., and WATTS, H. A., Royal Aircraft Establishment, South Farnborough, Hampshire. Jan. 31, 1935, No. 3155. [Class 80 (iii)] To reduce friction and render the mechanism more efficient, especially over long distances, spring means are connected to both ends of the flexible transmission member beyond the actuating and actuated devices so as to maintain it always under tension. The movable member 1, Fig. 1, slides in a casing 2 extending between an operating member 3 and an operated member 4, which may comprise gear wheels 3a, 4a, engaging projections on the inner member. The latter is continued at both ends beyond the wheels for connection to a spring 5 the other end which is anchored to a part rigid with the outer casing. The inner member may transmit tension only or both tension and compression. A tubular case 6, Fig. 2 is secured to the outer member 2 and has a number of slots 8 to provide an anchorage for a pin 9 to which the spring 5 is attached. In a modification, the single spring 5 is replaced by a number of springs. In a further modification the outer end of the spring is attached to a block adjustable by a screwed rod. Where the actuated end of the movable member is near the actuating end, as in Fig. 7, a single spring 5 may connect the adjacent ends. To facilitate passage of the inner member around corners, guide pulleys 15 may be employed. Specifications 243,041, [Class 80 (iii)], and 380,204 are referred to.

Filed: 1965-01-25
Abstract: 1,049,262. Welding by fusion; curving. KOCKUMS MEKANISKA VERKSTADS A.B. Jan. 25, 1965 [Jan. 31, 1964], No. 3163/65. Headings B3E and B3R. In a machine for welding stiffening ribs to plates, the plates are held curved as shown in Fig. 3 during welding so that when the welds 9 have cooled and the plates have been released the plates are substantially flat. In a machine for forming large panels reinforced with T-section ribs welded at the edges of their webs to the panels, plates 2 are moved transversely on a roller conveyer 3 by grippers on chains 4 and are welded to form panels by one or more welding heads moving along a beam 6. The panel is turned over and the reverse side of the joints are welded by one or more heads moving along a beam 8. The panel is moved to a welding station 43 over a bar 14, Fig. 5 (not shown). The bar 14 is raised by fluid pressure rams and is lowered on to selected abutments of different heights. Electromagnets 15 are lowered by fluid pressure devices to pull the panel into the required curved shape about the bar 14. A rib is secured on a carriage 11 by electromagnetic clamps. The carriage 11 and the rib move along rails 19 on to rails 29, Fig. 4 (not shown), at the welding station 43 the rails 29 having been previously lowered. Fluid pressure clamps 16 press the rib against the panel. The electromagnetic clamps are de-energized, the carriage 11 is withdrawn into the rails 19 and the rails 29 are raised. The rib is welded to the panel by a pair of submerged arc welding heads 18. Subsequently, the panel is moved for further ribs to be welded in place.

Title: Feed boxes for roll presses
Inventor: FITZHERBERT ALEC BENJAMIN
Filed: 1964-01-28
Abstract: 1,087,082. Feeding device for roller presses. COAL INDUSTRY (PATENTS) Ltd. Jan. 19, 1965 [Jan. 28, 1964], No. 3614/64. Heading B5A. The feed device for a roll press is carried by a mechanism which ensures permanent contact of the cheek plates of said device with the sides of the rolls 11, 12, despite axial movement of said rolls, e.g. that due to thermal expansion of the shafts 13, 14, upon which they are mounted. In the embodiment shown in Fig. 1 cheek plates 18 and 19 of the feed device are pivotally carried at 20 by bars 21, 22, themselves pivoted to machine part 23. The plates are permanently biased against the rollers by means of a compression spring 27 located about one end of a rod 25 which passes through bar 21 and is pivoted to bar 22. When the rollers move it can be seen that the above mechanism distorts and pivots to enable the plates to remain against the rollers. In a second embodiment, see Fig. 3, the feed device is reciprocated along cross-members 45, 46 by thermally expansive bars 47, 48. The expansive properties of the bars and the shafts 13, 14, upon which the rollers are mounted, are such that when heated to the same temperature, the amount of expansion of the shafts and the bars is the same, thus moving the feeding device bodily with the rollers and maintaining contact therebetween. This may be done alternatively by using e.g. an electrically operated screw jack mechanism instead of expansion bars.

Title: A Frictional Lock for the Joints of Artificial Arms.
Inventor: SIMMONDS GEORGE CLIFFORD
IPC: A61F2/58
Filed: 1919-02-18
Abstract: 136,381. Simmonds, G. C. Feb. 18, 1919. Limbs, artificial. - An elbow-joint is locked by an internally - acting bandbrake, which is released by the pull on the operating- cord prior to the rotation of the forearm. The upper arm carries a block A to one end of which a rubberfaced spring band D is anchored. The other end of the block carries rollers B round which the free ends of the band pass to a guided rod F. The forearm carries a metal ring I surrounding, and contacting with, the spring band. The initial pull on the operating-cord reduces the loop between the guid'es J, and so raises the rod F to release the brake. The brake is reapplied when the pull is seleased quickly, and then retains the forearm in the adjusted position; but the forearm can be lowered by releasing the pull gradually, so that the forearm has time to fall to any desired extent before the brake is reapplied.

Title: An improved means for controlling the evacuation of heavy materials from a jig wash-box for coal or other minerals
IPC: B03B5/24
Filed: 1937-02-12
Abstract: 492,259. Jig washbox. GIBSON, S. H. Feb. 12, 1937, No. 4158. [Class 82 (ii)] A means for controlling apparatus to evacuate heavy material from jig washers comprises a float which is disposed within a vessel distinct from the washbox and not subjected to the pulsations of the stratifying liquid and operated by increments of liquid abstracted from the crests of the pulsations of the stratifying liquid. Pulsations of liquid caused by a basher are led through a hole in the side of the washer up the pipe 13, Fig. 1, and the crests thereof are ejected over the weir consisting of a group of tubes 6 and are collected after passing through the pipe 7 in the vessel 10. The latter is fitted with an orifice 9 so that the level of the liquid therein is determined by the amplitude of the pulsations. and the float 11 will rise or fall accordingly. By means of the lever 18 attached to the valve 19 the float controls the flow of water in the pipe 20 and so regulates the speed of rotation of the rotor of the turbine 21. The turbine is geared to the shaft of the rotary gate 25 thus governing the discharge of the precipitated material through the opening 27. Fig. 7 shows means suitable for maintaining a minimum head of liquid in the vessel 10. A constant flow of liquid from a suitable source is directed by the tube 28 into the bend 29 through the tube 32 and into the intake 34. This maintains the float 12 at a constant level, any temporary overflow from the weir 6 causing a rise. To expedite the descent of the float the bend 29 is made rotatable. and is fitted with a pawl 35 making contact with the catch 36 on the float spindle. As the float rises the pawl moves freely but as the float descends the pawl rotates the bend 29 and swings it clear from the liquid stream. The orifices 33 and 9 may be fitted with screwed shanks to vary the effective length of the tubes to which thev are attached. The distance between the tubes 16 and the weir 6 which regulates the amount of liquid extracted from the pulsations by the weir, may also be varied. The weir 6 may also be adjusted to vary the level at which extraction of the liquid shall commence.

Abstract: 1,201,821. Automatic control of linear dimensions. NATIONAL RESEARCH DEVELOPMENT CORP. Jan. 18 1968 [Jan.27, 1967], No.4241/67. Heading G3R. [Also in Division B3] In a system for automatically maintaining a constant diameter of work turned in a machine tool, a proximity gauge detecting the radial position of a toolholder surface and a proximity gauge detecting the radial position of the workpiece surface diametrically opposite the portion being worked on, combine to control the radial position of the tool. As applied to a lathe, Fig. 4, a tool 35 is moved into the work by operation of a handwheel 29 to rotate a screw feed for the tool rest. At the same time a pneumatic nozzle 45, coupled to the tool rest through an endless belt linkage, moves toward the machined surface of the work at a point diametrically opposite the cutting point. The diameter of the work is indicated by a digital display 91 connected to a transducer 61 responsive to the movements of the tool rest and nozzle 45. When the desired diameter has been set, an electrical signal corresponding to the pressure at nozzle 45 and hence its distance from the work is added to a signal similarly developed from a nozzle 43 corresponding to the position of tool 35 relative to its support. The sum of these signals is compared with a reference signal 89, and any difference, indicating for example a change of diameter due to thermal or elastic distortion, is amplified at 83 to control the pilot valve 41 of a hydraulic ram which moves tool 35 relative to its support to restore the correct diameter. A further pneumatic nozzle 63 near tool 35 applies to a chamber 105 a pressure corresponding to the distance between this nozzle and the machined surface. When switches 85, 85A are closed, an electrical signal corresponding to this distance is applied, together with a signal representing the initial valve of this distance, to amplifier 83 so that the system is compensated for subsequent wear of the tool which developes a difference between the two signals. This compensating signal is up-dated periodically by intermittent camoperation of valves 103, 107 from the lead screw drive, and maintained constant during the intervals by the pressure in chamber 105. Production of a work profile corresponding to a template or punched tape is referred to. Application to internal boring is also referred to.
