Filed: 1922-09-18
Abstract: 206,969. Mitchell, 0. Sept. 18, 1922. Addition to 186,334. Reservoir pens -The selffilling reservoir pen described in . the parent Specification is modified by the provision in the axial tube A of an additional opening which is placed into or out of communication with the interior of the cup by the reciprocation of the latter, by the provision of an actuating- rod for the cup, and by the provision of a clearance between the cup and the barrel. The axial tube A is open at its rear end into the cup B and is provided with stops a, a<1> between which the cork disc C, frictionally engaging the interior of the cup, is slidable to cover and uncover an aperture a<2> in the tube. The cup B is attached to a finger-piece b by a rod b<1> passing through a gland D fixed in the rear end of the barrel. To fill the pen, the front end is immersed in ink and the cup B is drawn out by means of the finger-piece b. The cup carries with it the disc C until the latter is arrested by the stop a, so that the aperture a<2> is uncovered. Further movement of the cup causes air to be drawn through the aperture a<2> and tube A into the cup, ink entering the barrel through the passage 3 in the feed-bar 2. When the cup is pressed in, the disc C is first moved to cover the aperture a<2> and the air compressed behind the disc is forced out through the tube A and passage 5 in the feed bar.

Title: Improvements in continuous dyeing machines
IPC: D06B3/10
Filed: 1935-09-11
Abstract: <PICT:0450373/IV/1> Relates to continuous dyeing-machines in which yarn, ropes, fabrics, or chains of hanks are drawn into, and in a zigzag path through, the dye bath, and consists in means for facilitating the addition to the bath of a quantity of fresh liquor proportional to that withdrawn from the bath by the fabric.  To this end, the upper end of the tank or vat is so modified that only a small surface of liquid is exposed, changes of level of such surface being readily appreciable.  Fresh liquor is run into the tank continuously to replace that withdrawn by the fabric.  As shown in Fig. 1, the top of the tank 10 is largely closed by removable lids 15 and by the lower of a pair of wringing rollers 13 partially immersed in the dye liquor.  Narrow spaces are left for the entrance and exit of the fabric 12, and at these spaces the fall in liquid level due to the withdrawal of liquid by the wet fabric can be observed readily. Fresh liquor from a reservoir 22 is run into an auxiliary tank 20 connected to the tank 10 by an aperture 21.  The supply of liquor is controlled by a cock 25 which is set to maintain the liquid level in the tank 10 constant.  A shut-off cock 24 also is provided.  The supply of fresh liquor may be controlled by a float valve.  In a modification, the submerged closure for the top of the tank is furnished wholly by the lower wringing roller.  The wringing rollers and the guide rolls for the fabric may be mounted in a frame separable from the tank.  Where a fabric is subjected to repeated dyeings, the wringing rollers are arranged to wring the fabric only partially, so that a substantial quantity of liquor is removed even when the fabric has entered the tank in a wet condition.  This liquor is expressed from the fabric by a subsidiary pair of wringing rollers, and may be collected for further use.

Title: Elevator control system
IPC: B66B13/08
Filed: 1920-09-02
Abstract: 172,125. Marks, E. C. R., (Randall Control & Hydrometric Corporation). Sept. 2, 1920. Lift cages and doors, locking and unlocking and operating.-A switch in the circuit of the actuating motor is connected to the locking device of each well door so that the switch is opened when any door is unlocked and is held open until all the doors are looked. Each well door 3 has a notched bolt 4 which, when the door is closed, is engaged by a projection 27 on the arm 9 of a three-armed lever 7, 8, 9 mounted in a look casing 5. The arm 8 projects from the casing and carries a transverse pin 12. The arm 7 also projects from the casing and has a slot through which passes a vertically movable wire 13 suspended by a spring 14 and tensioned by a weight 15. A stop 16 is fixed to the wire above each arm 7 so that when any arm moves upwards, the wire is raised and the switch 20 in the circuit 17 of the motor 18 opened. At the same time the door is unlocked. The arm 7 is locked in the raised position by the engagement of latches 32, 30 with pins 34, 36 on the arms 9, 8. These latches are disengaged when the bolt 4 is inserted in the casing. The arm 7 is raised by depressing a pedal 31 on the lift, thereby bringing a shoe 28 on the lift into contact with the pin 12. When the motor 18 is running, a solenoid 49 is energized and its core 48 is raised, thereby moving a serrated bar 46 into locking engagement with a similar bar 45 attached to the wire 13. Upward movement of the wire is thus prevented, and consequently no door can be unlocked. When an hydraulic motor is used for actuating the lift, the switch 20 is arranged in a local circuit with a relay 38, Fig. 5, which actuates a switch 39 controlling a circuit containing solenoids 42. Brakes 43 are applied to and released from a movable part 44 of the motor by the solenoids.

Filed: 1935-09-12
Abstract: 462,682. Four - stroke engines; driving - gear. SCOTT, B. D. Sept. 12, 1935, No. 25372. [Class 7 (ii)] [Also in Group XXXIII] In a multi-cylinder aircraft engine, pistons in opposed cylinders 11, 12 are connected by single connection rods to crank-shafts 14, 15 which rotate in opposite directions and are geared to a 'single propeller shaft 21, or to coaxially-arranged propeller shafts. The shafts 14, 15 are either geared together directly or through a gear wheel 20 on the shaft 21 and an idler gear wheel 23. The axes of the cylinders, crank-shafts and propeller shafts may be in the same plane, or the shafts may be slightly offset. In a modification two sets of opposed cylinders are arranged in parallel planes, the crank-shafts being geared to a central propeller shaft so that the three shafts are in the same plane and the crank-shafts rotate in opposite directions. In a further modification each of the opposed cylinders is replaced by two or more cylinders arranged fanwise, their connecting rods being coupled by single connecting rods to the oppositely rotating crank-shafts. The engine being flat is especially suitable for building into the wings or fuselage of an aeroplane, and an arrangement is shown in which the engine cowlings project forward of the front line of 'the wings and present a stream-lined surface which does not increase the drag of the machine. Specification 431,687 is referred to.

Abstract: 958,169. Monitoring reactors. NUCLEAR POWER PLANT CO. Ltd., and A. E. I. -JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP], May 3,1963 [July 3, 1962], No. 25473/62. Heading G6C. In a weak link device for a thermocouple cable in a nuclear reactor, the sheath is removed from the cable for part of the length within the device, and the parts of the sheath on at least one side of the bared length is housed in a member adapted to move in a fixed casing'enclosing the device, movement of the member being restrained by a deformable member so that the member can only move on the application of a predetermined force which is smaller than that required to break the sheath but greater than that required to break the conductors. In Fig. 1 the cable 2 passes through a casing 1 and is supported by members 3 and 4 which are adapted to slide within the casing. For part of the length within the casing the sheath of the cable is removed and the bared conductors 5 are enclosed within an insulating tube 6. Member 3 is secured by a spring clip 8 which passes through apertures (not shown in Fig. 1) in the casing 1 and engages a recess 7 formed in the member. On the application of a predetermined force the spring clip is released and the force then applied to the bared conductors 5 is sufficient to break them. In an alternative, Fig. 4, the member 3 abuts a plug 9 having a tapered end portion 9a housing on a ledge 10 on the inner surface of the casing 1. The end portion of casing 1 has axial slots 11 formed therein so'that the end of the casing forms a pair of flexible limbs which are pushed apart on the application of sufficient force of plug 9.
Patent GB-254774-A (GB)
Abstract: 254,774. Cross, W. M. March 31, 1925. Compound &c. engines; vapour engines. - A system of generating power comprises a number of expansion stages or motors interposed between a generator and a number of heating stages through which the power fluid, water, mercury, sulphur-dioxide, &c., is circulated. The generator and heating elements constitute a single structure, and the fuel supply and the temperature of the power fluid are automatically controlled. The generator and heating element comprises a heavily insulated, horseshoe-shape, furnace enclosure supported by I beams 2, Fig. 1. Funnel-shaped, liquid-fuel furnaces formed preferably of carborundum brick are supported on a bed 3, and are supplied by lines 5 controlled by valves 6 fed by a main, fuel line 7 and a preheated air line 8. Vertical banks of preheating, vaporizing, and reheating or superheating tubes 11, 12, 13 are connected to headers at the front of the generator. Overhead tubes 14 arranged between headers 14a, 14b are connected to tubes 12. The furnace gives off radiant heat and combustion gases which pass through flues 15, 16, 17 and heat a preheater 18 for combustion air. The water or other medium is fed by pump 20, Fig. 3, to tubes 11. Partitions cause the water to move to and fro between the headers 11<a>, 11<b>. After leaving the tubes 11 by pipe 23, the preheated water is similarly circulated through tubes 12, then passes through pipe 24 to tubes 14, then by pipe 25 into the superheating tubes 13 which are arranged as first, second, and third reheaters 13<c>, 13<d>, 13e respectively. From the reheater 13<c> the fluid passes to the first engine or stage of a turbine, reciprocating or rotary motor. The exhaust from this motor element passes to the second reheater 13<d>, then to a second motor element, and so on until the fluid passes finally to a condenser 35. The temperature of the fluid in the preheating and vaporizing stages is automatically controlled by an electrothermostatic control 37 inserted in pipe 25 controlling the supply 22 by a valve 41. The fuel supply is similarly controlled by pressure from a branch 42 affecting a valve 43. The temperature of the fluid supplied to the separate stages is automatically controlled. The control of the system ensures the correct temperature of the fluid from reheater 13<c> for the first motor element. The temperature of the second stage supply is controlled by injecting cooling-water or other fluid through pipe 50 into the supply of the reheater 13d, which cooling-medium is controlled by a device 49 affected by the temperature of the second stage supply. The fluid medium works with a maximum pressure of 1000-2000 lbs. per square inch and a 500 lb. drop in each stage.
