Abstract: 1,061,900. Dividing engines. SHEFFIELD TWIST DRILL & STEEL CO. Ltd. Dec. 20, 1965 [Dec. 24, 1964], No. 52401/64. Heading G1X. A dividing engine for marking a dial 2 comprises an indexing mechanism A for stepwise feeding of the dial relative to a marking position, a mechanism to produce a reciprocating movement of a scriber 5 across the surface of the dial 2 at the marking position, and a cam 18 rotatable in synchronism with the indexing mechanism to produce an extended movement of the scriber at periods coinciding with the reciprocating movement but only for example after every five or ten such movements. The indexing mechanism A is driven by a crank 53 and lever 54 operating through a panel and ratchet mechanism. The mechanism for reciprocating the scriber is also driven from a crank 20 on the same shaft as the crank 53, operating through gearing and levers to pull a cable 13 thus rotating a lever 12 which actuates a rack and pinion arrangement to reciprocate a carriage 6 on which the scriber 5 is mounted. The cam 18 is rotated continuously and is provided with a cam follower 17 forming a pivot point for the lever mechanism operating the cable 13. Two cam plates 25, 26 are mounted on the cam 18 and are radially adjustable thereon, and are arranged so that at each fifth or tenth stroke of the scriber 5, the cam follower engages with one of these plates 25, 26 to move the pivot point of the operating mechanism and thus lengthen the stroke of the scriber 5. The plates may be adjusted to provide a longer mark at each fifth stroke and an even longer mark at each tenth stroke. The depth of cut of the scriber 5 is determined by an adjustable roller 4 mounted adjacent the scriber.

Abstract: 1466408 Extruding ethylene oxide polymer UNION CARBIDE CORP 5 Dec 1974 [10 Dec 1973] 52698/74 Headings B5A and B5B [Also in Divisions C3 and A5] The moulding of a molten ethylene oxide polymer, e.g. by extrusion, injection moulding, blow moulding, or slot casting, is facilitated by the blending with the polymer of a fugitive moulding aid comprising 4 to 200 parts by weight of water, per 100 parts of polymer, to obtain a melt flow index of 0À05 to 20 decigrams per minute, under specified conditions. The water permits lower extrusion pressure and evaporates from the moulding, e.g. to 2% by weight of a film continuously produced by inflation of an extruding tube, and thereby produces a cooling effect. Preferred ranges are 10 to 20 parts of water, and 0À1 to 10 decigrams per minute melt flow index. The polymer may be a homopolymer of ethylene oxide, or a copolymer with propylene, or butylene, or styrene oxide. In the examples, a homopolymer of specified molecular weight was blended with specified percentages of water on a two roll mill, and cut into pieces which were extruded; (I)-(III), to produce films by inflation of a tube issuing from the extruder die; (V), to produce a monofilament which was then uniaxially stretched at a 7À8 to 1 ratio; (VI) to produce a tube using an air cooled mandrel. Extrusion is effected at a polymer temperature of 55 to 120 C., and the extruded product may be a sheet. The polymer may have a weight average molecular weight of 250,000 to 5,000,000, and may contain a dye, a stress cracking, or oxidation, or heat, or ultra violet stabilizer, a surfactant and/or a filler. The films obtained by inflation of an extruded tube may be of a density of 1À0 to 1À2 gm./cc., and may be made into uniaxially oriented tapes of higher tensile strength. The unoriented films may be made into a bag for containing a toxic water dispersible powder, e.g. an insecticide, fungicide, or bactericide, the bag being enclosed within an outer bag of water insensitive polyethylene, polypropylene, polystyrene, or vinyl chloride resin, the outer bag being removed and the inner bag being inserted in water to disintegrate and permit the powder to dissolve.

After n - 1 pulses have been counted by counter 71, decoder 72 produces an output which inhibits AND gate 5 and the multivibrator ceases to oscillate. When counter 61 has counted m - 1 clock pulses, decoder 62 provides an output which retriggers monostable 1 to restart oscillations. The clock signal and the m- 1 output from decoder 62 are applied to NAND gate 65 which produces a "0" level pulse during the (m - 1)th clock pulse. In a similar way NAND gate 75 produces a "0" pulse output during the (n - 1)th output pulse. The two NAND outputs are applied to a bi-stable 8 which is set to one state or the other depending on which pulse occurs first. The "0" or "1" output from the bi-stable 8 is applied to an integrator 84, 85, 86 which produces at point 3 a control voltage for adjusting the oscillator frequency.

Abstract: 1,136,756. Automatic control. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. Dec. 21, 1965 [Dec. 21, 1964], No.54204/65. Heading G3R. In a system for automatically regulating a process, the sense of regulation is changed directly from one sense to the other in dependence on the state of the process and a dead time of constant predetermined length is observed after each changeover so that a further changeover cannot occur during this period which is made substantially equal to the lag of the process. In Fig. 1, when a variable of an industrial process 1 deviates from a desired value, a detector 9 applies a positive signal to an AND circuit 13 the output of which then operates a changeover switch 8 to reverse the sense of a correcting signal applied from a source 5 to the process. The output from circuit 13 is also applied to a logic circuit 17 which includes a delay unit so that its output, which is normally positive and applied to the other input of AND circuit 13, is reduced to zero for a predetermined period to prevent detector 9 from producing another reversal of the sense of correction during that period. This period, which is made equal to the lag of the system, allows each reversal to become effective before another can occur. If, after the delay period, the variable has not been corrected, circuit 13 produces another reversal and continues to do so at regular intervals while the condition lasts. The input to circuit 17 may be applied through an OR circuit the other input to which receives a signal when engaging the control system so that an initial delay period is introduced before the first reversal can take place. Detector 9 and corrector 8 may be associated cyclically with a plurality of variables of the process. Detector 9 may be responsive to a time derivative of a variable so that the latter is maintained at an optimum such as a maximum.

[Also in Division F2] An anaesthetic vapouriser of the by-pass type, which seeks to provide a constant anaesthetic concentration at various flow rates of the carrier gas, comprises a body casing 1, closed at its lower end and having a top closure plate 2, in which gas entering at an inlet 3 flows into a recess 14 in the facing part 12 of a control valve 13 which seals against the top plate 2, from which some of the gas flows down by by-pass passage 15 leading to a port 17 controlled by a by-pass valve 18, operated by a temperature sensitive device 19 and responsive to the internal temperature of the vapouriser so that the pressure drop across and restriction to flow offered by the by-pass valve increase as the total volume of gas flow through the apparatus increases, gas flowing from valve 18 via a restricted passage 20 into an axially disposed chamber 21 and thence through a passage 22 to an outlet 4. The rest of the gas flows through a passage 16 into an annular passage 24, through a series of holes 25 into a very narrow annular passage 26, and thence onto the surface of the volatile liquid anaesthetic 8 contained within the body casing 1. A certain amount of anaesthetic vapour is picked up by the gas stream and the mixture flows up an annular passage 7 between two cylindrical wicks 5 and 6, where further vapourisation occurs, and thence via a groove 9, a passage 10, a radial slot 10a in the top plate 2 into the control valve 13 from which the gas-vapour stream passes to an outlet 4 where mixing with the by-passed gas stream occurs. The facing part 12 of the control valve 13 may be made of polytetrafluoroethylene and has a variable depth and width groove 11 in it in the form of an almost complete annulus. This groove may be brought into communication with the radial slot 10a and an exit hole 23, both in the sealing face of the top plate 2 the hole 23 leading to the outlet 4 by rotation of the valve 13 using a knob 31 secured to it, for control of the gas-vapour mixture flowing up the passage 7.

This difference is held in 21 and compared at 17 with the count registered at 12 to give a signal at 18 in the case mentioned. If on the other hand, the comparison at 17 shows the count at 12 less than or equal to the difference in 21, the zone length in register 23 is gated 52 to 12 (where it is added in) and to a space expand register 54. In this case, comparisons at 17 will eventually produce a signal at 18 (perhaps after one or more further uses of gate 52 as above), and this causes justification computer 58 to calculate the increase in interword spacing (from the normal value which is entered into a register 60) required to bring the line ending within the line ending zone, using the contents of register 54 and the number of spaces indicated by a counter 47.
