Title: Process of separating sulphur from gases containing hydrogen sulphide
IPC: C10K1/18
Filed: 1934-07-25
Abstract: 430,865. Gas - purifying materials. OTTO & CO., GES., DR. C., 9, Christstrasse, Bochum, Germany. July 25, 1934, Nos. 21760 and 21761. Convention dates, July 25, 1933 and Dec. 5, 1933. [Class 55 (ii)] [See also Group III] Hydrogen sulphide is removed from coke oven &c. gases and sulphur is recovered therefrom by washing the gas with a liquid containing sulphur dioxide and one or more organic bases which combine with and remove from the sphere of action the deleterious thio acids formed during the reaction between the hydrogen sulphide and the sulphur dioxide. The bases employed include pyridine, quinoline, aniline, naphthylamine and substituted amines such as dimethyl aniline. As the vehicle for the sulphur dioxide, aliphatic or aromatic hydrocarbons may be used. To prevent the precipitation of the bases as sulphites, a liquid, such as methyl or ethyl alcohol, phenol, naphthol, &c., is added which is soluble in the oil and acts as a solvent for the sulphites of the bases. Wash oil adhering to the separated sulphur is removed by filtering or centrifuging and washing with a solvent therefor, e.g. benzene. Water which is formed during the reaction between the hydrogen sulphide and the sulphur dioxide dissolves the thio salts of the base which is recovered, after separation of the aqueous solution from the wash oil, by heating the solution with a mineral acid to decompose the thio acids with separation of sulphur after which an alkali carbonate or ammonia is added to render the solution alkaline, the liberated base being separated. In a modification, the treatment with the washing liquid is effected in two stages ; in the first, the washing liquid does not contain much sulphur dioxide and the sulphur formed is precipitated while in the second the sulphur is dissolved due to the presence of excess of sulphur dioxide. Thus, crude gas containing hydrogen sulphide passes through a pipe a and dip bell b into a saturator c from the bottom of which sulphur is discharged by an injector d. The gas passes through a pipe e into a washer f furnished with grids and supplied with wash oil through a pipe g, the purified gas leaving by the pipe h. A part or the whole of the oil from the washer f is led through a pipe i to the saturator c or through a pipe k directly to the discharge pipe m of the saturator and through the regenerating plant n back to the washer f.

Title: Improvements in or relating to apparatus for cutting food stuffs
IPC: B26D3/18
Filed: 1924-09-16
Abstract: 237,452. White, A. E., (Hobart Manufacturing Co.). Sept. 16, 1924. Cutting and slicing vegetables &c. - Food-cutting apparatus comprises a receptacle 21 for the food, food-cutting means, and an interlock between the lid 26 of the receptacle and the cutting means so that when the lid is raised the cutting means cannot be operated and vice versa. A stationary removable grid cutber 22 co-acts with a reciprocating pusher member 28 moving entirely clear of the trough 21 and carried by an arm 33 integral with a crank arm 31 pivoted at 32 to the gear casing 20. The cover 26 is slotted for the passage of the arm 33 and has an overhang 34, and the juices of the cut food are carried away by a groove 29 in the bottom of the trough. A driving shaft 50 rotated in any suitable manner carries a worm 53 coacting with a worm gear 55 rigid with a carrier 56 loose on a shaft 59. Pins 63 on this carrier 56 engage in notches 62 in a clutch member 61 slidably keyed on shaft 59 and pressed to the left, as shown in Fig. 3, by a spring 64. At the other end the shaft 59 carries a disc 60 having a crank pin 68 surrounded by a block 69 which slides in a yoke 70 in the crank arm 31, so that as the shaft 59 is rotated through the clutch the arm 31 is oscillated to press the vegetable through the cutter and then to return. The cover 26 is pivoted at 25 to the casing and has pivoted to it at 76 a link 75 pivoted at 77 to a plunger 78 moving in a guide 79 in the casing 20. This plunger 78 co-operates with a cam slot 80 in the clutch member 61 so that if, during the rearward movement of the pusher member 28, the plunger 78 is depressed, by the raising of the cover 26, into this cam slot the clutch member 61 is slid axially and disengaged from the pins 63. Thus if the cover is maintained raised the cutting actuating means are disengaged. If, however, cutting has commenced the plunger 78 rides upon the periphery of the clutch member 61 and the cover 26 cannot be raised. The cam slot 80 is, however, sufficiently long to allow the operator to raise and lower the cover rapidly to insert another vegetable. Pusher-member construction. In a modification the pusher 28 is resiliently mounted on the crank arm so that the line of pressure between the potato and the pusher member is always normal to the face of the latter. This gripping surface 35 of the pusher mav be grooved concentrically or covered with rubber provided with suitable projections. Cutter grid construction. The cutter may be of the usual shape, cutting pieces of square crosssection, or, in a modification, the cutter is made in two relatively adjusted parts so that thick slices, thin slices, or lozenge-shaped pieces may be cut according to the relative adjustment of the two parts.

Title: Improvements in thermostatically controlled electrical switching devices for refrigerators
Inventor: MCGOWAN ERIC
IPC: H01H37/12
Filed: 1951-09-19
Abstract: 720,281. Thermal switches. BRITISH THERMOSTAT CO., Ltd. Sept. 11, 1952 [Sept. 19, 1951], No. 21996/51. Class 38 (5) A refrigerator control switch, which can be latched for defrosting by rotation of a rangesetting knob, is arranged so that, on completion of defrosting, it is unlatched automatically and normal operation of the refrigeration cycle resumed. The control knob spindle 4 has a threaded portion 4a carrying a spring register 6, keyed against rotation. A compression spring 5 presses against the register 6, and bears at its lowest end against an abutment plate 8, which is axially adjustable on a threaded spindle 9. The lower end of the spindle 9 is located in a recessed plate 10 on a bellows 2. Spindle 9 also carries adjustable stop members 12, whichco-operate with the operating cam 13 of an over-centre switch 3. A cam plate 14, attached to spindle 4a, has a projection 14a adapted to engage a lug 15a on a slide member 15. On the opposite end of member 15 is a further lug 16 permanently engaging a spring blade 17 which has a slot 19 through which the operating arm 20 of the deadcentre switch passes. In defrosting, the control knob is rotated to the " off " position, in which the projection 14a abuts lug 15a and moves member 15 to the right,.so moving spring 17 to the position shown in Fig. 1 and opening the switch 3. The member 15 is latched in this position by a leaf-spring 21 abutting the lug 15a. The control knob may then be turned to set the required normal refrigeration range without altering the defrosting setting. At a predetermined temperature, the member 15 is unlatched by an adjustable screw 23, which is held in a bent-up portion 22 of abutment plate 8, acting on the spring 21, Fig. 3, to release lug 15a. The member 17 then passes to a position flush with the casing, and the switch is thereby freed for operation on the normal refrigeration cycle. In a modified form of release, Figs. 7, 8 (not shown), the screw 23 is vertical and engages a vertically-disposed extension on the spring 21. A visual means for indicating when defrosting is occurring consists of a pivoted coloured arm carrying a projection which engages a slot in the member 15, so that when 15 is set for defrosting, the arm is pivoted so as to be visible through a hole in the casing, Figs. 9, 10 (not shown).

Title: Improvements in or relating to doubling apparatus for textile fibres or yarn
IPC: D01H1/10
Filed: 1929-07-18
Abstract: 331,702. Berthier, J., and Baudonnel, C. V. July 18, 1929. Spindle apparatus; stop-motions. - In a doubling and twisting apparatus of the type in which a bobbin for the threads to be doubled is mounted on a carrier, about which a rotor turns and imparts a double twist, a stop-motion is operated by the relative motion of electric contacts either when the tension in the thread increases beyond a predetermined limiting value, or when the carrier tends to rotate. In Fig. 1, the bobbin 1 is mounted on the carrier 2 which is pivoted by means of ball-bearings on the journals 3 and 4, the latter being supported in bearings 3<1> and 4<1>. The rotor consists of two flanges 6 and 7 having a cylinder 5 between them. Apertures 8 are provided to allow access to the bobbin. The thread a is drawn round the rollers 41, 42 and 43, round the pulley 9<1>, through the tube 9 to the pulley 9<11> and thence to a drawing apparatus. The roller 43 is mounted so that it can rise or fall vertically with varying tensions in the thread. For excessive tension, the roller is raised against the pull of a small adjustable spring and carries with it the insulated metal arm 46, which thus makes contact with the two halves of the split pulley. If the carrier 2 rotates, the freely hanging member 39 which is in the form of an inverted V, and is insulated from the frame of the machine, comes into contact with the split pulley. The latter consists of two insulated metal discs mounted on the journal 3 between'the members 39 and 46, and connected to slip rings adjacent to the driving pulley 10. Brushes bear on these rings and are connected in series with the supply mains and a switch controlling the driving motor. Thus when the two halves of the split pulley are bridged, either through excessive thread tension or rotation of the carrier, the circuit to the slip rings is completed and the apparatus stopped.

Title: Improvements relating to control systems for electric power transmission systems employing synchronous alternating current dynamo-electric machines
Filed: 1946-07-24
Abstract: 610,799. Transmitting mechanical power. REYROLLE & CO., Ltd., A., ROBERTSON, A. T., BAYLES, J. W., and HANSON, E. R. July 24, 1946, No. 22065. Addition to 589,749. [Class 38 (iv)] [Also in Group XXXVII] In a control system for a synchronous motor fed by an alternator, such as in a ship propulsion system, as described in the parent Specification, a first movement of a control member in one direction from a neutral position sets a directional switch for forward rotation of the motor, a similar movement in the other direction from neutral position sets the directional switch for reverse rotation of the motor, a second movement of the controller in either direction closes the motor and alternator armature circuit, whilst a final movement of the control member in either direction accelerates the prime-mover driving the alternator. Movements intermediate of the second and final, in either direction, may bring about the subsequent operations associated with starting and accelerating the motor described in the parent Specification. Fig. 1 shows the modifications necessary to adapt the controller described in that Specification for use in the present invention. The control wheel A operates a transverse shaft B which is capable of movement away from a neutral position in one direction only and which, by rotation, effects all the starting and accelerating operations other than the selection of the directional switch 16-18, which is controlled in dependence upon the initial direction of rotation of the wheel A through pin, fork and lever mechanism 13-15 operated through bevels 10, 11 driven by a shaft A<SP>2</SP> directly geared with the wheel A. In order that the shaft B may rotate in the same direction irrespective of the rotational direction of the wheel A, a shaft 23 directly driving shaft B is arranged to be driven by shaft A<SP>2</SP> either directly through a dog clutch 24, 25, or indirectly through a differential 19-22, this dog clutch and another, 30, 31, for locking the carrier 21 of the differential, being selectively actuated from the lever 15 through links 26, 28, 32. In a modified arrangement, the shaft B is driven by either of two shafts carrying loose pinions oppositely rotated by the control wheel A and selectively clutched to their shafts by a cam operated by direction-controlling lever 14.
