Title: Improvements in the recovery of valuable products from coal gases
IPC: B01D53/04
Filed: 1921-08-17
Abstract: Coal or coke-oven gas, previously freed from tar, cyanogen compounds and part of the ammonia content, is passed at ordinary or slightly raised temperature through a number of towers containing active charcoal, such as is obtained by charring wood with zinc chloride. In the first towers, all the benzene hydrocarbons are absorbed; in the next towers, the hydrogen sulphide is removed in the state of free sulphur, after a sufficient amount of oxygen-containing gas with or without ammonia has been added; finally, if desired, the ethylene hydrocarbons are absorbed in the last towers.  By employing an arrangement of interchangeable towers, the process may be conducted in a continuous manner.  Instead of absorbing ethylene as such in the last towers, it may be converted into ethylene compounds by interaction with halogens &c. in the presence of the active charcoal, and these compounds are then retained.  The absorbed substances are removed at intervals, for instance, by extraction with a solvent or by expulsion with steam; and by diminishing the pressure in steps during the operation, a fractional removal of the absorbed substances may be effected.  Specifications 153,297, 170,152, [both in Class 55 (ii), Gas manufacture &c.], and 177,362, [Class 2 (iii), Dyes &c.] are referred to.ALSO:Coal or coke-oven gas, previously freed from tar, cyanogen compounds and part of the ammonia content, is passed at ordinary or slightly raised temperature through a number of towers containing active charcoal, such as is obtained by charring wood with zinc chloride.

Title: Apparatus for checking the failure of speedometers and mileage or revolution counters in vehicles
IPC: G01P13/00
Filed: 1927-08-25
Abstract: 301,106. Ach, N. Aug. 25, 1927. Speedometer transmission mechanism; odometers; rest or motion indicators and recorders.- Relates to apparatus for indicating or registering the cessation of rotation of the shafts operating speedometers, odometers or revolution counters on motor vehicles while the vehicle or engine is running. For this purpose a mass oscillatable by the vibration of the engine or running vehicle is normally held steady while the meter shaft is running but is freed, upon stoppage of the shaft, to show an indicator, or operates an odometer at an abnormal rate, or print from timedriven wheels. A lever 1, Fig. 1, carrying a weight 6 balanced by a spring 7 has a pawl 3 engaging a ratchet wheel 4 coaxial with a wheel 5 of the revolution counter, and has a pin 12 for engagement by a detent 10 while the latter is free from contact with a pin 9 attached to the speedometer pointer 8. When the pointer is at zero the detent 10 is withdrawn from the pin 12 and if the vehicle or engine is running the lever 1 actuates at an unusual and noticeable rate the revolution counter. In the form shown in Fig. 2. the pointer-operated detent 10 frees a weighted lever 1 which drives a ratchet wheel 4 having a pin 20 to rock a lever 21 and withdraw a spring- controlled stop arm 22 from a pin on a wheel 18 of a train 16, 17, 18 which through pin-wheel and spring-urged hammer prits a record from time wheels 15. The actuating spring of the train 16, 17, 18 is tensioned by the ratchet wheel 4. In a further modification a frame 34, Fig. 3, swings on the driving shaft 26 of a speedometer and carries gearing controlled by an escapement 33, so that by its inertia., while the shaft 26 is running, the frame 34 is swung against the action of a spring 35 from a stop 36 over to a stop 37 and thus into position to impede a finger 38<a> on the oscillatable weighted lever 38. In the form shown in Fig. 5, the meter-driving shaft 26 carries on a radially slotted disc 39 a sliding weight 41 flexibly connected through an axial bore in the shaft to a, longitudinally movable spring-controlled stop 46 for arresting the oscillatable lever 47. The latter when freed during the running of the vehicle or engine by the stoppage of the shaft 26 actuates a counter 50 at a greater rate than normally. In the form shown in Fig. 8, the oscillatable lever 47 carries a coloured weight 60 in position to be seen through an aperture 61 in its casing. The vibration-preventing stop 57 is carried on a drum 56 frictionally engaged internally by a spring-controlled lever 54 pivoted on an arm 53 on the meterdriving shaft 26.

Abstract: 1400554 Time switches EATON CORP 15 May 1972 [18 May 1971] 22613/72 Heading H1N [Also in Division H2] A programme control unit, suitable for example, for a washing machine, comprises a main rotary programme switch unit 47, a subsidiary rotary programme switch unit 1, rotatable about a common axis 28, a timing device 36 arranged to drive the main unit 47 mechanically in a step-wise motion, means for coupling the subsidiary unit 1 to the timing device 36 in one or more discrete relative angular positions such that they rotate together, and disabling means dependent on the angular position of the main unit 47 for mechanically disabling the coupling means. As shown a motor 46 drives a disc 36 by means of its peripheral teeth 3, and a cam 4 thereon oscillates a lever 22 against spring 20 to cause a pawl 23 to step a main programme cam 47 by teeth 19 thereon. A coaxial subsidiary programme cam 1 carries a pawl 9 urged by a spring 13 such that a projection 35 engages a recess 40 in disc 36 as the latter rotates, thereby entraining cam 1 with disc 34, unless a blocking lever 15 is moved by spring 38 to lift the pawl 9 and prevent coupling. Lever 15 is controlled by a sensing arm 17 thereon following a track 18 on cam 47. Thus the drive to cam 1 is coupled and uncoupled only when cam 1 itself is in a predetermined position (i.e. pawl 9 opposite lever 15) and also the main cam 47 is in a predetermined position (dependent upon shape of track 18). This may be used, for example, to ensure that a washing machine motor reversal by contacts operated by recesses 2 cannot occur during a high speed spin programme set by cam 47. A number of pawls 9 and more than one recess 40 may be provided, thus providing coupling at several discrete relative angular positions, but the pawls and recesses must be so angularly staggered that only one pawl can engage at a time thus permitting uncoupling by lever 15 at a single position. Circuits are disclosed (Figs. 3 and 4, not shown) for ensuring that spin can start only when the reversal contacts are set for a given direction of rotation (See Division H2).

An apparatus for forming and securing a block bottom closure in a bag blank whereby the blanks are fed through the apparatus and simultaneously aligned in a direction transverse to the feed direction, there being means for applying adhesive to selected areas of flaps on the blank and folding them over one another. Plastics or similar material bags with face flaps opened out and corner flaps folded adjacent their inner surfaces are fed by conveyer belts 1 having stopping blocks 2 moving at a slower speed than the belts 1 so that the leading edge of the bag is aligned perpendicularly to the direction of motion and fed between rollers 3, 4, 4<SP>1</SP> (Fig. 5, not shown), which are mounted on a transversely movable frame 5. The rollers are interconnected by gears 6 and the roller 3 is connected via a telescopic element 6<SP>1</SP> and spring 7 to a cam 8 while the frame 5 has a racked element 9 which engages a toothed wheel 10 connected to a magnetic clutch 11. With a bag between the rollers 3, 4, 4<SP>1</SP> the cam 8 acts on the telescopic element 6<SP>1</SP> to shift the frame in the direction of arrow H until the bag intercepts a photo-electric cell 12 which locks the clutch 11 and prevents further transverse motion of the frame, rollers and bag; any further movement of the cam being absorbed by the telescopic element 7. The transversely aligned bag is transferred to perforated metallic belts 15 under the action of pincers 17 and nozzles (not shown) for feeding into two similar adhesive applying units where adhesive from a tank 19 (Fig. 6, not shown) is transferred by a roller 18 to a sector 25 and brushes 27 connected to a shaft 26 for applying the adhesive to chosen areas on the flaps; by means of shafts 30, arms 31 and pivoted projections 32 the movement of the brushes is accelerated when in contact with the flaps. After the adhesive is applied the bags are conveyed to a flap folding unit (Fig. 7, not shown) comprising a pair of plates 37, 38 which are rotated by means of pivoted levers 43, 43<SP>1</SP> to fold over the face flaps about foot members 41, 42 which define the folding lines and are connected to retractable elements 39, 40 in turn connected to endless chains for movement in co-operation with the bags.
