Title: Improvements in or relating to rivet setting machines
IPC: B21J15/10
Filed: 1939-06-07
Abstract: 533,355. Eyeletting-machines. BIFURCATED & TUBULAR RIVET CO., Ltd., and PATERSON, L. M. June 7, 1939, No. 16708. [Class 43] [Also in Groups XXII and XXX] In a rivet-setting machine the rivets are fed along a vertical, inclined or horizontal guide 22 by an endless element runnng adjacent the guide and provided with an outstanding member projecting into the track. The rivets are fed to a split holder 18 and setting tool 13 arranged as described in Specification 487,152 but in inverted position, i.e. with the stem of the rivet upwards and the anvil 10 above it. The anvil is raised, to allow movement of a large piece of work e.g. an aeroplane wing, by a toggle 65 and counter-balanced hand-lever 68 and then lowered. In this position the lever 68 is opposite to and can be moved at right-angles to its previous movement to operate a spring-returned pin 81 connected to a bolt-tripping device 84 of a onerevolution clutch mechanism as described in Specification 399,942. [Group XXIV]. This causes the crank shaft 11 to lift the tool 13 which pushes the rivet through the work and sets its on the anvil 10 The cam 17 of the clutch mechanism, before it arrests the rotation, engages a lever 28 connected to a bolt-tripping mechanism 30, Fig. 2, thus causing a clutch 31 to transmit power from a pulley 32, driven by the same motor 49 as the shaft 11, to gearing 34 and a chain 23, Fig. 1, thus causing a projection 25 thereon to transfer a rivet from the slide 21 to the opposite end of the slide 22. The clutch 31 also drives, through reduction gear 33, Fig. 2, a shaft 38 having cams 37, 40 of which the former then closes a one-revolution clutch 39 to drive a crank shaft 41 and, by means of rods 43 and a spring tongue 35, push the rivet into the holder 18 and the latter opens the clutch 31. The hopper mechanism 28 may be constructed as described in Specifications 294,754, [Class 89 (iii)], and 348,224.

Title: Process for the treatment of natural juices extracted from sugar-containing plants
IPC: C13B20/14
Filed: 1960-05-16
Abstract: In the treatment of natural juices extracted from sugar containing plants, e.g. cane and beet, buffering matching the natural pH of the juice is effected before clarification or any further treatment. Preferred buffers comprise phosphoric acid and/or a salt thereof. Sodium hydroxide or sodium carbonate together with phosphoric acid may also be used as buffer mixtures. In any subsequent treatment of the juice any additive which increases the pH of the juice is balanced by further phosphoric acid or phosphate addition to ensure that throughout treatment the pH of the juice is held constant at its natural value; for example, when lime is added for clarification purposes, acid, e.g. phosphoric acid, is added simultaneously promoting in situ precipitation of dicalcium phosphate.

IPC: B61F5/04
Filed: 1967-04-15
Abstract: 1,205,071. Railway vehicle undercarriages. GLOUCESTER RAILWAY CARRIAGE & WAGON CO. Ltd. 19 April, 1968 [15 April, 1967], No. 17387/67. Heading B7L. A railway bogie comprises sideframes 1, Fig. 1, each provided with two spaced hollow guide columns 5 defining therebetween a bolster guide within which the corresponding end 6 of a bolster 4 is slidable vertically during normal movement on suspension springs 7, wherein at least one column 5 houses and supports therein damping means 13, 25, Figs. 2 and 3 through the intermediary of a damping control member 36 which follows vertical movement of the bolster 4 whereby a greater damping force is applied to the bolster when loaded than that applied when the bolster is unloaded (tare condition). The damping means comprises a friction shoe 13, having a facing 14 engaging a side face 15 of the bolster end 6 and a spring 25. The latter urges upper and lower collets 16, 17 between upper and lower guides 12, 19 of the column 5 and against the shoe 13. The inner end of the spring 25 engages a plate 30 abutting the collets and the outer end engages a plate 33 in abutment with a vertical arm 43 of a bellcrank 36 pivoted to the column 5 at 37 and whose horizontal arm 38 has a convex surface 48 to engage a pad 40 on the bottom of the bolster. The collets 16, 17 have planar surfaces 26, 27 engaging convex surfaces 23, 24 of the shoe 13, which is therefore self-centring. In another embodiment Figs. 5 and 6 (not shown) the outer end of the spring 25 abuts a yoke pivoted to two levers pivoted at their upper ends to the opposite sides of the column (5). The levers, at their lower ends, have rollers engaging a cam surface depending from the bolster 4. The cam surface has upper and lower vertical surfaces joined by a curved surface whereby a constant damping force is provided for a light load range and a constant but increased force is applied over a more heavily loaded range. Other embodiments employing cam levers pivoted at their lower ends to the column 5 and operating through a lever or yoke are described with reference to Figs. 7 to 10 (not shown). The cams may be arranged to provide an increasing damping force during upward movement of the bolster during vibration of the latter with the guides and a decreasing damping force during downward movement during such vibration.

Filed: 1971-05-27
Abstract: 1386596 Shearing FREDERICK SQUIRE Ltd 18 May 1972 [27 May 1971] 17417/71 Heading B3W [Also in Divisions B4-B5] A strip of material 5, e.g. flexible synthetic resin material, from the outlet of an extruder, or rigid or semi-rigid material, or thin metal, is continuously delivered over a stationary but adjustable table 4, against the upstream edge of which it is cut by the radially extending blades of a shear 7 which is urged along its axis towards the table 4 by a spring and is unidirectionally and intermittently rotated on a shaft 8, by a reciprocating linear pneumatic motor 20, one stroke of which rotates the shear 7 through 360 degrees divided by the number of blades. The cylinder of the pneumatic motor 20 is pivotally mounted at 21, and the piston shaft 23 of the motor is pivotally connected to a shaft 16 carried by an arm of a "U"-shaped member 14, the arms of which are freely rotatable on the shaft 8, the intermittent motion of the shear 7 being effected by a pawl 15 rotatably carried on the shaft 16 and urged by a spring 17 against a ratchet wheel 13 fixed to the shaft 8. Rotation of the shaft 8 in an opposite direction is prevented by engagement of a detent spring 24 with the ratchet wheel 13, and continuous rotation of the shear 7 is prevented by a stop 34 which is intermittently pivoted into and out of abutting engagement with a leading edge of a blade of the shear 7 by a further linear pneumatic motor 31. The motors 20, 31 are actuated from a common pressure air source, via a reducing valve connection to the motor 31. The motors 20, 31 are single acting, with a spring return from the driving stroke and may be arranged to operate at a fixed speed controlled by a timer mechanism, or each stroke of the motors may automatically be effected when a predetermined length of material has been fed past the stator shear. The motors may be controlled by the system of Specification 1,386,597. The shear 7 is biased towards the leading edge of the table 4 by a coil spring around the shaft 8, Fig. 4 (not shown), and the table 4 is adjustable towards the shear 7. For the cutting of flat strip material, the shear blade cutting edges are slightly curved as shown, and the table 4 is flat, but the cutting edge of the table 4 may be shaped to correspond with shapes other than flat which are being cut.
