Title: Improvements relating to position control systems
Inventor: ENGLISH BRIAN BOX
IPC: G05D3/12
Filed: 1965-05-28
Abstract: 1,082,074. Control devices. FERRANTI Ltd. May 19, 1966 [May 28, 1965], No. 22865/65. Heading G4H. The required position of a member is set up on switches S0, S1 (indicating units and decades respectively), the actual position of the control member being held on switches P0, P1 connected in series with the switches S0, S1. When a switch is closed the motor is energized to effect a coarse approximation i.e. to balance the decade switches S1, P1, the fine approximation then being effected. In the embodiment described in which the required position is represented by the number 25 and the actual position by the number 16, alternating current flows via contact 10 in switch P1 and diode D2 through which only the negative half-cycles may pass to switch S1 and hence to an input terminal B of a control circuit. The negative half-cycles are applied by a diode D14 to the base of transistor T1 which is thus cut off. When the switch S is closed transistor T4 conducts so that relays RA, RB, RC are energized to drive the motor in the required direction. Switches P0, P1 are driven by the motor, switch P0 at ten times the speed of switch P1, until the wiper of switch P1 moves on to the contact 20 as S0 reaches the zero position. The alternating current is then applied to the terminal B and also via diodes D5 to D9 negative half cycles are applied to the terminal A. A capacitor C1 presents a low impedance to the A.C. so that the negative halfcycles pass through diode D14 as before until the motor has rotated the switch P0 to the contact 5. Then alternating current is applied at both terminals A, B and resistors R1, R2 and capacitor C1 are such that transistor T2 is cut off and transistor T1 is maintained in its cut-off state so that the relays are de-energized and the motor is stopped.

Poultry are plucked by flexible fingers or flails 22 on a shaft 19 co-operating with projecting flexible plucking elements 17 on the inside of a preferably cylindrical drum or cage 11 which is rotated at a different, preferably slower speed in the same direction as the shaft (or in the opposite direction if desired, according to the Provisional Specification). The flails and/or fingers on the shaft and/or drum may be arranged in helical fashion. Flanges 12 on the drum rest in grooved wheels 13, one pair of which are driven by a motor 16. The shaft 19 is belt-and-pulley driven about seventeen times as fast as the drum, e.g. at 350 r.p.m., by a motor 21, and has an axial duct 26 for spraying water into the drum or cage through holes 27. The drum which may be slightly inclined downwards at the exit end, is open-ended to receive and remove fowls and the closure plate 32 at the exit end is movable in an axial direction to allow discharge of the fowls on to a sloping grid 36 through which the feathers fall for collection. The housing 5 of the machine is divided to provide drum, discharge and motor sections 8, 9, 10 respectively, and its support feet 3 are adjustable. The machine may be designed for continuous automatically controlled operation and hot air may be introduced into the drum or compartment 8.

Patent GB-900172-A (GB)
Title: New bis-sulphinic acid compounds
Inventor: SHAW JOHN THOMAS
Filed: 1958-07-21
Abstract: The invention comprises bis-sulphinic acids of the general formula HO2S-R-SO2H and salts thereof, wherein R represents a saturated cyclo aliphatic hydrocarbon radical containing five or six carbon atoms, the two sulphinic groups being attached to different carbon atoms, or a saturated aliphatic hydrocarbon radical containing 4-18 carbon atoms, the two sulphinic groups being separated by a straight chain of at least 4 carbon atoms.  They may be prepared by reduction of the corresponding sulphonyl chlorides, which may be obtained by chlorination of the corresponding sulphonic acids or alkyl bis-isothiouronium salts.  The reduction is preferably effected with sodium sulphite yielding the sodium salts of the sulphinic acids which may be isolated as such or converted into less soluble salts; acidification yields the free acids.  Examples describe the preparation of (1) 1:4-butane bis-sulphinic acid using magnesium or sodium sulphite yielding the magnesium or sodium sulphinate which is acidified to liberate the free acid; the zinc sulphinate is prepared from the sodium salt and zinc chloride; in like manner there are prepared (5) 1:5-pentane bis sulphinic acid and its sodium and zinc salts and (6) 1:10-decane bis-sulphinic acid, (7) 2-methyl butane-1:4-di-sulphinic acid, (8) 2:5-hexane bis-sulphinic acid, (10) 1:4-cyclohexane bis-sulphinic acid, (11) 1:12-dodecane bis-sulphinic acid and (12) 1:18-octadecane bis-sulphinic acid and their sodium salts.  Numerous other values for R are exemplified.  The compounds react with formaldehyde to yield the corresponding hydroxy methyl sulphones; thus (9), the bis-sulphinic acid of (1) is reacted with aqueous formaldehyde to yield the bis 1:4-(hydroxy methyl sulphone) butane.  These sulphones may be used in treating textiles (see Group IV(c)).  The a :o -bis sulphonyl chlorides of decane, dodecane and octadecane are prepared by reacting the corresponding dibromo-alkane with ethanolic thiourea, isolating the resulting isothiouronium bromide and reacting it in aqueous solution with chlorine. 2-Methylbutane-1:4-bis-sulphonyl chloride is prepared by reacting the corresponding dibromo compound with alkyl halide and an alkali metal sulphite and treating the resulting sodium sulphonate with PCl5.ALSO:Textile fabrics are rendered wrinkleresistant by treatment with hydroxy methyl sulphones obtained by reacting formaldehyde with a bi-sulphinic acid of the general formula HO2S-R-SO2H wherein R is a saturated cyclo aliphatic hydrocarbon containing 5 or 6 carbon atoms, the sulphinic groups being attached to different carbon atoms, or a saturated aliphatic hydrocarbon radical containing 4-18 carbon atoms, the two sulphinic groups being separated by a straight chain of at least 4 carbon atoms.  In Example (9), cotton fabric is padded in an aqueous bath containing 1 : 4-butane bis(hydroxy methyl sulphone) and MgCl2, and then dried and heat-cured.  Numerous other values for R are exemplified.  The preparation of the compounds is described (see Group IV(b)).

A pharmaceutical tablet-forming compression moulding machine comprises a stationary table 2a, Fig. 5 (not shown), which supports a plate 3 and die 4, and a vertically reciprocable framework wherein rods 7 pass through table 2a, are connected at their upper ends by a crosshead 6, carrying a plunger 5, and are connected at their lower ends by a crosshead 9 which is driven by machinery located beneath table 2a. Powdered material is fed by a screw 48, Fig. 4, to a passage 47 from which it is collected by a channel 58 during each revolution of a rotating distributer 57. Also during each revolution the outlet end of channel 58 passes over die 4 to deposit powder therein. To increase the rate of flow of the powder the outlet of passage 47 and both ends of channel 58 are in the form of arcuate-shaped slots, Figs. 7, 8 (not shown). The crosshead 9, Fig. 5 (not shown), is driven by a shaft 12, Fig. 4, via an eccentric 12a and connecting-rod 11 and the same shaft actuates a bottom plunger 30 via a cam 37. The plungers 5 and 30 substantially rise and fall together except for a dwell period of the latter during final compression, a vertically adjustable shock-absorber, comprising a bearing head 38a and spring 45, cushioning plunger 30 during this period. Plunger 30 ejects each tablet from die 4 when it rises and is vertically adjustable, via a plunger bearer 31, by rotation of a rod 33 keyed to a screwed support 32 to bring the upper surface of plunger 30 flush with the upper surface of plate 3. Plunger 5 is also vertically adjustable by rotation of a wheel 28 and the co-operation of a frusto-conical gear 25 with frusto-conical toothing 24. Each tablet ejected from die 4 is swept around plate 3 by a curved surface 63, Figs. 3 and 8 (not shown), of distributer 57 to be delivered to a shoot 62 via sloping surface 60 and aperture 61.
