Abstract: 418,032. Stapling. WRIGHT, W. E., Savile Lea, Savile Road, and FLEMING, BIRKBY, & GOODALL, Ltd., West Grove Mill, both in Halifax, Yorkshire. July 14, 1933, No. 19911. [Class 89 (iii).] A machine for making transmission belting &c. comprising means for inserting one or more longitudinal rows of staples through the superposed plies of material of which the belting is formed, includes means for feeding the belting, to a variable extent, step-by-step past the stapling elements, and means for adjusting the belting transversely of said elements. The machine comprises feeding elements 8, 9 for the staple wire 7 and a rocking lever 3 for actuating the clinching ram 4. The staples are driven upwardly through the belting and then clinched by the ram. The belting is fed by rollers 15, 16 journalled in uprights 13, 14 extending from a slide 12 which is adjustable across a work-table 10 by a screw 22 with handwheel 23. The roller 16 is rotated intermittently by a ratchet 25 and a pawl 26 driven from a crank 30 by linkage 28, 29 which is adjustable to vary the feed stroke. The upper roller 15 can be raised, against a spring 38, by eccentrics 35. In use, a length of belting is fed through whilst a row of staples is inserted, the slide 12 is then adjusted transversely by the screw 22, and the belting is again fed through for the insertion of a second, parallel, row of staples. The table 10 carries suitable guides for the belting and, preferably, is capable of swivelling to allow staples to be inserted obliquely.

Title: Control system for synchronous drive of dc motor
IPC: H02P6/22
Filed: 1973-04-26
Abstract: 1438511 Automatic control of speed CANON KK and CANON SEIKI KK 26 April 1973 [28 April 1972 11 July 1972 (2)] 19955/73 Heading G3R [Also in Division H2] A speed-control arrangement for a D.C. motor 14 or a brushless motor uses trains of pulses for both the reference and fed back actual speed signals in a gating circuit 11 to alternately set and reset a bi-stable circuit to apply pulses of current to the motor and is provided with a phase shifting circuit 16 to delay the reference pulses which are then used to reset the bi-stable in the absence of a fed back pulse signal. Thus each reference pulse sets the bi-stable even when the motor is running slow. In the case of a brushless Hall plate motor the fed back speed pulses can be derived from a separate tachometer, the inactive stator windings or the Hall plates. The bi-stable circuit applies pulses to the Hall plates and the width of the pulses is changed to control the speed of the motor. Magnetic or optical transducers can be used for producing the actual speed pulse signals, Fig. 14 (not shown), and the gating and phase shifting circuits described, Fig. 9 (not shown) use NAND logic. The dividers 3, 8, are used to change the controlled speed of the motor.

Abstract: Dilute H2SO4, obtained by diluting an acid sludge, formed in the H2SO4 refining of petroleum fractions, with water and separating the resulting aqueous phase, is purified by extracting with a liquid hydrocarbon, or a liquid mixture of hydrocarbons, and stripping the extracted acid with an inert gas. The extractant should <PICT:0860370/III/1> have a high aromatic content, and a b.pt. below 250 DEG  C., e.g. naphtha, white spirit, benzene, kerosine, or the aromatic extract obtained by extracting kerosine with a selective aromatic component solvent, such as liquid SO2, and may be used in amount 5-15%.  Extraction and stripping may be at 0-60 DEG  C.  Acid sludge from tank 2 has water added at 4 to give 40-70% acid, and passes through mixing coil 5 to settling-tank 6.  The oil phase is withdrawn through 7 to burning and the tar interface through 9, while the aqueous phase is removed through 8, mixed with liquid hydrocarbon at 10 and passed, through mixing coil 11 at 50 DEG  C., to settling tank 12.  Hydrocarbon is removed at 13, while dilute H2SO4 passes to packed column 15 at 45 DEG  C. where stripping gas, e.g. N2, or petroleum refinery fuel gas enters at 16.  The H2SO4 from 15 may be further purified by treatment with a solid adsorbent, e.g. active carbon, clay, or silica gel.

Title: Method of automatically controlling the roasting of materials containing roastable sulphur
Inventor: WITTMANN GEORG
IPC: C22B1/10
Filed: 1960-06-10
Abstract: <PICT:0886786/III/1> In the roasting of materials containing roastable sulphur in two fluidized layers with a separate supply of an oxygen-containing gas to each layer, the amount of oxygen-containing gas supplied to the first (pre-roasting) layer is automatically controlled by a regulator situated in the second (after-roasting) layer so that a rise in temperature in the second layer reduces the supply of oxygen-containing gas and vice versa, and the supply of raw material to the first layer is automatically controlled by a regulator situated in the first layer so that when the temperature in the first layer rises above a certain level more raw material is supplied, and vice versa, thereby tending to keep the temperature constant.  The oxygen-containing gas supply to the second layer is preferably so controlled by a regulator that the supply remains constant regardless of the height of the layer. The heights of the individual layers may be controlled independently of the supply of material thereto, by means of pressure or differential pressure regulators which control the solids discharge means from the layers.  Preferably the supply of oxygen-containing gas to the first layer is controlled by a regulator which is varied within fixed limits about a hand-set mean value by the temperature sensitive device in the second layer.  In the figure, raw material from hopper 1 is fed into the first fluidised (preroasting) layer 4 by means of a plate feeder 2, the rate of feed being controlled by a temperature sensitive device 11.  The supply of oxygen-containing gas to the first layer is controlled by temperature sensitive device 14, which is situated in the second fluidised (after-roasting) layer 7. Pressure regulator 12 controls the rate of discharge of solids from layer 4 to layer 7, and pressure regulator 15 controls the discharge of solids from layer 7.  The regulator 16 maintains a constant rate of supply of oxygen-containing gas to layer 7.  Any dust leaving cyclone 6 is burnt in a combustion zone 9, the supply of oxygen-containing gas to this zone being controlled by temperature regulator 17 in such a way that the temperature reaches a maximum.

Abstract: 934,117. Feeding webs. SCHWEIZERISCHE INDUSTRIE-GES. June 7, 1961 [June 9, 1960], No. 20472/61. Class 100 (1). A web 3 is fed from a spool 2 over a guide table 5 and looped over guide rollers 9 rotatably mounted in cantilever fashion on a fixed arm 8 and guide rollers 14 similarly mounted on an arm 13 centrally pivoted at the end of a rocking lever 11 as shown. The web is then fed by intermittently driven nip rollers 7 through knife blades 30 into a processing machine (not illustrated). The guide rollers are mounted in cantilever fashion so that they pass between each other allowing the rocking lever 11 to take the position shown in broken lines. When a spool 2 has emptied and the end of the web runs over a gap 5a in the table 5, a lever 23 drops down, releasing a pawl 25 thereby applying a spring-biased brake 27 to the web 3. The processing machine can continue to function, using the web stored in the loops between the guide rollers, whilst a second spool 2a has its web attached by an adhesive band to the end of the previous web. The rocking lever 11 drops under its own weight, the movement being damped by an hydraulic damping device 16, when the brake 27 is released. Brakes 20 operated by a cam means 22 at the pivot end of the lever 11, stop the spool from over spinning when the rocking lever 11 reaches the position A. The cam means 20 also operates a switch 18 when the rocking lever 11 reaches the position B, turning off the power supply to the processing machine being fed.
