Title: Force balance instruments
IPC: G06G5/00
Filed: 1972-03-21
Abstract: 1383571 Force balance mechanism SYBRON CORP 21 March 1972 [28 May 1971] 13135/72 Heading G1W A force balance mechanism comprises a lever 18 pivoted at 20 about axis A 1 , a bellows 1 acting on lever 18 via plate 22, a lever 8 pivoted at 7 and having a roller 29 at its end which runs on a track 30 on lever 18, a bellows 2 for applying a force via lever 9 to turn the lever 8 about axis A2 and thus apply a counterbalancing force to lever 18, and a bellows 3 for applying a force via lever 10 to turn the lever 8 about axis A 3  and thus adjust the position at which the counterbalancing force is applied to lever 18. When the pressure in bellows 1 increases, lever 18 pivots about axis A 1 , and the baffle on the lever 18 approaches a nozzle 23.  Nozzle 23 is supplied with air via a restriction 31, and as the baffle moves nearer the nozzle, the pressure in lines 26 and 32 increases, and the increased pressure applied to bellows 2 and 3 increases the counterbalancing force applied by bellows 2, and moves the point of application of the counterbalancing force away from axis A 1 . When a new balance is achieved for lever 18, the pressure in line 32 is proportional to the square root of the pressure applied to bellows 1. When the pressure in bellows 1 falls below a predetermined value, roller 29 abuts a screw 35 and is prevented from moving further towards axis A 1 . In this condition the roller 29 is detached from track 30, and the force from bellows 1 is counterbalanced by that from bellows 3, the pressure in bellows 3 then being proportional to that in bellows 1. The pivot 7, Fig. 2, comprises a pair of members 50, 51 joined together by a resilient wire 57 and a resilient plate 53. The pressure applied to the bellows 1 may be the pressure developed across a restrictor as a result of fluid flow, and the pressure in line 32 is then proportional to the fluid flow and may be used to control the flow rate. The bellows may be replaced by diaphragms, pistons, or Bourdon tubes, or by hydraulic, electrical or magnetic devices. A booster relay may be provided in line 32, and a pressure gauge or recorder connected to that line.

Title: Improvements in or relating to thread winding machines
IPC: B65H54/42
Filed: 1962-04-06
Abstract: 998,098. Winding threads. W. REINERS. April 6, 1962 [July 15, 1961], No. 13269/62. Heading D1J. In a thread winding machine having a grooved drum 1 traversing the thread on to a take-up spool 7 the reversal points of the groove 4 are covered by plates 10, 10a that co-operate to form a guide channel preventing the thread F from being thrown sideways off the grooved drum should the thread break at the reversal points. The additional grooves 5, 6 extend around only a part of the drum periphery following the reversal points and are intended to receive the substantially tensionless end portion of a trailing thread from the bobbin 7, should the thread break or become exhausted, and so prevent the thread end from running over an end of the bobbin and possibly becoming wound on the bobbin spindle. The plates 10, 10a carry pins 15 forming a zig-zag path, as shown, the purpose of the path being to delay engagement of a re-tied thread with the groove 4 over the full length of the traverse drum 1 until the thread has become tank. In Fig. 2 the plates 10, 10a can pivot independently about a rod 11. In a modified construction Fig. 4 (not shown) the plates are integral at their lower ends so that they pivot as one about the rod 11.

Abstract: 1,180,093. Variable resistance transducers. P. HUET. 21 March, 1967 [22 Sept., 1966], No. 13269/67. Heading H4J. [Also in Division G1] A microphone comprises a flexible diaphragm of electrically non-conductive material (e.g. mica, glass, quartz, cellulose acetate or synthetic plastics), on which is deposited an arcuate layer of electrically conductive or semi-conductor material (e.g. bismuth, antimony, tellurium, or germanium). As shown, Fig. 2, there are two arcuate portions of conductive material b1, b2 on one face each extending through approximately 180 degrees and there are identical arcuate layers on the lower face (Fig. 3, not shown) displaced by 90 degrees from those on the upper face. The diaphragm may be peripherally clamped as shown, Fig. 8, and have a damping chamber with outlet 18 below it. In an embodiment for sensing vibrations in the ground as shown, Fig. 7, the diaphragm 1 is backed by a chamber, formed between the diaphragm and a relatively thick steel plate 14, and filled with liquid. This is to prevent puncturing of the diaphragm under high variations in pressure. The conductive layer portions may be connected to form a resistance bridge the unbalance voltage of which corresponds to variations of the resistance of the portions as a result of strain when the diaphragm is subjected to stress.

Abstract: 392,357. Moulding plastic substances by tamping-machines. CUVELIER, P. A. I., Rue de la Gare, Marly, Nord, France. May 10, 1932, No. 13494. Convention date, Dec. 5, 1931. [Class 87 (ii).] In a moulding-machine in which the material is compressed by a rammer in a mould which is shaken, and in which the rammer bears on the surface of the moulded material while the mould is raised from its base to expel the moulded article, the rammer 1 has a vertical extension 6 on which are keyed two spaced collars 22, 23 between which two plates 19, 20 separated by a spring 21 are adapted to slide, the plates co-operating with fixed abutments 25, 26 so that on upward movement of the rammer 1 the plate 20 engages the abutment 26 to compress the spring 21 and thus accelerate the fall of the rammer whereupon the plate 19 engages the abutment 25 and supports the rammer at the level of the compressed material through the spring 21. The rammer 1 is raised by a lever 10 pivoted at 11, which lever is oscillated by a roller 15 which engages a spiral cam track 16 rotating on the shaft 18. The roller 15 slides laterally in the lever 10 and is brought into engagement with the centre of the cam track 16 by a lever (not shown) and disengaged at the top by a wedge-shaped projection on the cam surface. The rammer is retained in its raised position by a lever 30. A hopper 31 with a door 32 is used for filling the mould. In a modification the rammer is raised by a pawl or an eccentric which engages a pivoted toothed sector 45 connected to the rod 6, or the pawl 44, Fig. 5, may be carried by a pivoted rod 42 and operated by a cam 40. The lever 10 may also be raised by a hook 82, Fig. 6, carried by a lever 80 oscillated by the cam 78. In a further modification, Fig. 8, the rammer is raised step by step by hooks 71, 76 carried on levers 70, 75 operated by a double cam 73, which hooks engage projections 72 alternatively. The mould 2 is shaken by hooks 56, 57 carried on connected levers 48, 52 which are oscillated by a cam 46, Fig. 2. The hooks 56, 57 engage projections 60, 61 on the rods 63, 64 and thus raise the mould and then allow it to drop on to the abutments 4. The formed article is ejected from the mould by allowing the rammer to rest on the moulded surface and detaching the base 3 of the mould. Teeth 65 are allowed to engage under the projections 61 and the mould is raised step by step by the hooks 56, 57 leaving the article on the base 3. In a modification, Fig. 7; the base 3 may be carried by springs 83 and, when the supports 4 are removed, the rammer 1 which carries rods 88 forces the base 3 away from the mould with the moulded article on it. The various devices described for raising the rammer may also be used for raising or shaking the mould.

Abstract: 947,205. Automatic temperature control. C. U. R. A. PATENTS Ltd. July 21, 1960 [April 21, 1959], No. 13627/59. Heading G3R. [Also in Divisions F4, G1 and H2] The temperature of the steam or water in a boiler furnace is maintained constant by regulating the on/off time ratio of an electric motor driving the furnace stoker. A heat sensitive phial 85 in the water space acts on one end of a pivoted lever 74, Fig. 4, through a bellows arrangement 81. The other end of lever 74 carries a pash rod 73 engaging a bimetallic strip 65 forming one arm of a pivoted U crank, the other arm 68 carrying the actuating member 69 of a switch 71, 72. A coil 86, in parallel with the outer contacter 87, is energized when the switch 71, 72 is closed, to heat the arm 65 which deforms to open the switch 71, 72 and cut off the stoker motor. The on/off ratio of the motor is determined by the setting of lever arm 74. The air supply and its distribution under the travelling grate 1 is determined by a main damper 53 and dampers 22, 23, 24, Fig. 1 operated by a phial 59 heated by a coil 62 and bellows arrangement 54 and by a phial 37 heated by a coil 38 through a bellows 34 and push rod 27 respectively. The coils 62, 38 are connected in parallel to be energized only when the motor is running. The position to which the fire extends on the grate 1 is controlled through a U tube 50 mounted above the end of the grate, Fig. 1. That air from the U tube 50 acts on a phial 46 and bellows 39, Fig. 3, to close a switch 43, 44 if the temperature at the U tube 50 is higher than is justified by the setting of the push rod 27 operation, the distribution dampers 22, 23, 24. A coil 63, energized by the closing of contacts 43, 44, heats a large, lugged phial 61 to open the main air damper 53 sufficiently to cause the fire to shorten. Since the phial 61 is slow acting and larger than the phial 59 the fire position control is about independent of the setting of the main air damper determined by the rate of fuel supply.
