Patent GB-599296-A (GB)
Title: Process and apparatus for dyeing, bleaching or other liquid treatment of textile fabrics
IPC: D06B3/20
Filed: 1945-10-11
Abstract: <PICT:0599296/IV/1> A web of fabric is dyed, bleached or otherwise treated with liquid by drawing it downwardly and upwardly through a series of passageways surrounding the web and causing a stream of the treating liquid to flow continuously lengthwise in the same direction as the fabric through the said passageways.  The rate of flow of liquid and the speed of the fabric are such that the treating liquid will have a depth at the points of highest elevation of the fabric just sufficient to cover the moving fabric.  Apparatus described consists of a tank 4 containing water, heating coils 5 and inner walls 6 shaped to form vertical partitions or dams 7, 8 and 9.  The partition 9 is slightly lower than the top of the roll 20, and the following partitions 10, 11 and 12 are slightly lower than the corresponding partitions 7, 8 and 9, respectively.  A baffle 21 with lower roll 25 is inserted in each of the wells formed by the partitions 7, 8, 9, . . . so as to leave a narrow passageway for the web and surrounding liquid which enter the apparatus through funnel 15.  Elevated rolls 27 and 28 are driven and serve to lessen the tension on the fabric. The baffles 21 with rolls 25 are raised out of the wells in order to facilitate festooning of the fabric when starting up the apparatus.  The apparatus may be used for dyeing fabrics with two or more dyestuffs which have different affinities for the material, with vat dyes, substantive dyes, sulphur dyes, diazo and naphtol dyes.

The propeller A is mounted within a horizontal tubular chamber B secured to the lower end of vertical chamber C containing a spindle E which is rotated through the gearing shown from the propeller, the spindle F forming part of the gearing passing through an aperture in the lower end of the chamber C. The spindle E carries at its upper end a permanent magnet G, or an electromagnet, beneath a plate D of non-magnetic material which completely closes the upper end of the chamber C. Mounted above the plate D is an armature J carried by a pivoted arm K so that it can move towards the magnet G against the constraint of a spring L each time the poles of the magnet approach the vertical plane of the armature, At its outer end the arm K carries a contact K<1> co-operating with a fixed contact I<1> to complete an electric circuit to operate indicating &c. devices.
Patent GB-928271-A (GB)
Title: Improvements in capacitor winding machines
Inventor: HINDS RONALD
IPC: H01G13/02
Filed: 1960-08-05
Abstract: 928,271. Capacitors. BRITISH INSULATED CALLENDER'S CABLES Ltd. May 3, 1961 [Aug. 5, 1960], No. 27277/60. Class 37. [Also in Group XVI] The terminal tab feed mechanism of the capacitor winding machine described in Specification 928,272 comprises means for carrying out the following steps:- stopping the mandrel in a predetermined angular position when a predetermined amount of capacitor has been wound, inserting a first terminal tab, rotating the mandrel through a predetermined angle, inserting a second terminal tab and again rotating the mandrel to continue the winding operation. Initially, clutch 95 is energized and the mandrel rotates at the high speed. When a predetermined amount of strip has been wound, one of the ears on the timing cam operates a switch to de-energize clutch 95 and energize slow-drive clutch 103. The second track on the timing cam now operates a further switch to energize a solenoid which causes a detent 134 to approach 126 the clutch 103 being deenergized just before the engagement of the detent and disc and the mandrel stops. An extension 136 on detent 134 operates a detent 137 which closes a switch to energize a tab feed clutch 106 to rotate shafts 119, 116 to operate the tab feed mechanism to feed one tab to the capacitor. When the tab has been inserted a cam 138a on shaft 116 releases detent 134, when the switch controlling clutch 103 is again energized. The mandrel is now driven at the slow speed through 180 degrees to the next position for inserting a terminal when detent 141 engages disc 126. The spacing between the tabs can be altered by adjusting the relative position of the detent discs of each pair. Screws 142, 143 allow for adjustment of the relative positions of the three detent discs to compensate for the effects flattening and tightening of the roll during winding, when it may become necessary to insert the tabs on different radii. The mechanism (Figs. 10, 11) for feeding tabs to rods 50, 51 projecting parallel to the " nip rollers " of the machine includes a pawl 176 and ratchet 177 the duration of engagement between which can be adjusted to adjust the length of metal foil forming each terminal. The foil is cut by a blade 181, and feeders 50, 51 are rotated clockwise and anti clockwise to allow the terminal first from feeder 50 and then from 51 to fall between the " nip " rollers, the two operations being so timed that the mandrel rotates a set amount between them. Modifications.-The apparatus is designed for the insertion of three pairs of tabs but may be modified for the insertion of two only by putting the feed mechanism out of action at the second set of tabs. In order to prevent the slowing and stopping of the mandrel a section 161 of the rim of the cam 151 operating the appropriate switch and an equivalent section from cam 150 is removed and the appropriate detents are put out of action. Specification 928,273 also is referred to.

The waste is dried in dryer 1 and fed via rotary vane feeder 2, to generator 3 containing a grate 4 to which air is supplied via pump 5. The generated gas passes through cooler 6 and electric filter 7 where tar and water are separated and passed to sedimentation tank 8 from which the water and dissolved hydrocarbons pass to steam generator 9 and thence in vapour form to generator 3. The gas is combusted in steam generator 10, the combustion gases being passed through heat exchanger 11 and electric filter 12 prior to release to the atmosphere via chimney 13. Air heated in exchanger 11 passes via pump 14 to dryer 1 and then through condenser 15 for removal of absorbed water. The gas may be burned in the combustion chamber of a lime, cement or like furnace, e.g. in combination with fuel oil or powdered coal.

Title: Improvements in devices for indicating or recording wheel loads on vehicles
IPC: G01G19/10
Filed: 1928-09-25
Abstract: 310,269. Becker, R. E. Sept. 25, 1928. Apparatus fitted to road vehicles.-In a device for indicating or recording wheel loads on vehicles, of the kind wherein a medium is compressed in a. cylinder by a piston and an indicating or recording device is actuated thereby, a transmission mechanism is provided at each end of the vehicle axle for transforming the vertical movements of each end of the axle into rotary movements of corresponding cams both of which act upon the piston rod. Beneath the floor 1 of the vehicle is secured a cylinder 2 containing a piston 9. A rubber membrane 5 divides the piston from an air chamber 3 to which indicating and recording instruments may be attached at unions 7,8. A valve 6 permits the addition of air if necessary. The movements of the piston are damped by glycerine which may flow through passages 11. A spring 13 tends to restore the piston to the position shown after movement to the left. At each end, the axle 19, Fig. 4, is connected by a coupling-rod (consisting of an air cylinder 20) to an arm 18 secured to a shaft 16 mounted in the side frame of the vehicle. Each shaft 16 carries on its inner end a cam 14 or 15, adapted when rotated to press upon a roller 12 carried by the rod 10 of the piston 9. When the vehicle is in an unloaded condition, both cams touch the roller 12 and the indicating or recording member is set at zero. If the vehicle be uniformly loaded the vehicle springs are uniformly deflected and both cams act on the roller and a corresponding indication or record is obtained. If, however, one side is more heavily loaded than the other, one cam only acts on the roller whilst the other lags behind and the indicating device consequently always indicates the state of the more heavily loaded road wheel. When a record of the loading is produced on a clockwork-driven disc additions and removals of load, or shocks suffered through a bad running surface are recorded.
