Title: Improvements in or relating to regulating devices for prime movers
IPC: G05D13/00
Filed: 1927-11-30
Abstract: 281,668. International General Electric Co., Inc., (Assignees of Allgemeine, Elektricitõts Ges.). Nov. 30, 1926, [Convention date]. Fluid governors; fuid relays.-In a governing device for prime movers, a regulator controlling the supply of motive fluid to a servo motor operating the inlet valve of a prime mover is subjected both to the pressure of the steam supplied to the prime mover and also to an independent force acting in opposition thereto. The pilot valve 1 controlling the servo motor 2 is pivoted to a rod 3 which is pressed upwards by an independent force which in this case is a diaphragm 16 under the pressure of the fluid supplied to the servo motor. The steam pressure acts on the upper side of the rod being communicated thereto through the lever system shown. The point at which balance of the two forces occurs is varied by adjusting the position of a fulcrum 22. This adjustment may be automatically performed by connecting up the fulcrum with the piston of a cylinder 21 subjected to the pressure set up by an oil pump 5 driven by the turbine. The movement of the piston is biassed by a weight 23 and springs 24. In a modification, the pivoted steam nozzle 13 controls the supply to the servo motor and is controlled in one direction by a spring 14 and in the other is subjected to steam pressure transmitted by a member 12. For this case the oil pump 5 controls the cylinder 8 a member 9 working between collars 10, 11 enables the pump to take charge of the regulating valve. when certain limits are passed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter. A regulator 2, Fig. 1 (Cancelled), takes up a position dependent upon the pressure and speed of an oil pump 1 and moves a nozzle 3 which directs pressure oil against a control aperture 4 leading to the main regulating valves 5. When the speeds falls the nozzle is raised to be more aligned with the orifice and the valves 5 are opened up to increase the steam supply and restore the speed. The setting may be varied by moving the link 18 and varying the influence of the spring 19. In a modification, the pivoted link is acted upon by a lever system actuated by pistons under the influence of the main steam pressure. The nozzle device may be replaced by a piston valve 12, Fig. 3 (Cancelled), operated by a link which is jointly controlled by the speed control 15 and a control 16 under the influence of the pressure in the regulating valve system 13. A pivoted weight 17 replaces the return springs, and the setting may be varied by the gear 18. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in wet gas meters or other apparatus having float controlled valves
IPC: G01V8/02
Filed: 1922-11-25
Abstract: 211,930. Crowther, G., and Liverpool Gas Co. Nov. 25, 1922. Ball and float valves for use with wet gasmeters, liquid-measuring apparatus, hotwater delivering apparatus, &c. A number of floats and connecting means are arranged so that one float is detained while another is free to move to a predetermined position, on arrival at which it frees a previously-detained float and is itself detained thereby, the frreed float actuating a valve or valves. Fig. 1 shows the application of the invention to a wet gas-meter in which the water on reaching its highest and lowest levels in the reserve chamber 15 opens and closes the gas valve 16. The valve-operating mechanism comprises two floats 1, 2 the float 1 being mounted on a lever arm 3 pivoted at 4 and the float 2 being carried by a triangular arm 7 pivoted at 8. In operation, water supplied through the cup 12 to fill a chamber 13 overflows through a pipe 14 to the reserve chamber 15 and tends to raise the float 1. The float 1 is, however, detained by the engagement of a roller 5 on the arm 3 with the lower surface of a cam 6 on the arm 7 until the water level rises sufficiently to lift the float 2. The float 1 then rises suddenly and in doing so throws a counterweighted arm 9 past its mid position. The counterweighted arm then lifts the valve 16 by engagement with discs 17 on the valve stem. On the water level in the reserve chamber falling by the operation of the spoon 24 the float 2 is maintained in its raised position until the float 1 falls sufficiently to release the rollers from the cam 6. As the float 2 falls a projection 19 on the' arm 7 engages the arm 9 and draws it back past its mid-position thereby suddenly closing the valve 16. In a modification, the secondary arm is mounted on the pivot of the arm 7.

Abstract: 429,183. Electric welding ; electric switches ; electric supply apparatus. HOLLAND, E. W., and CAESAR, T. W., 95, Kentish Town Road, HASELDEN, G. A., and TOOLS & MACHINERY SUPPLIES, Ltd., 54, Fetter Lane, both in London. Nov. 24, 1933, No. 32958. [Class 83 (iv)] [See also Groups XXXV and XXXVII] An electric spotwelding apparatus comprises a hand frame carrying electrodes with flexible leads connected to a source of current together with an operatoroperated switch for initiating the current flow and an automatic switch for breaking the circuit after a predetermined time interval. Small irregularly shaped articles such as dental plates may thus be welded. The electrodes 18, 19 are carried by insulating bushes and secured by screws in the split ends of a pincer-like hand frame 17. The flexible leads 15, 16 are connected to the terminals of the secondary 14 of a transformer, the primary 13 of which is connected to the supply terminals 11, 12 through a foot switch 33 and an automatic switch 31. The switch 31 is normally closed, but is opened after the desired interval by an electromagnet 34 connected through the switch 33 and in parallel with the primary circuit 13. The core 37 of the magnet, which is preferably arranged vertically, is normally urged downwards by gravity and by a spring. The switch 31 consists of a gapped rotary member 44 connected to the lead 30 and normally engaging a contact spring 45 connected to the lead 32. The member 44 is connected to the core by a rod 42 and crank pin 43. After the work has been adjusted between the electrodes the foot switch is closed to complete the welding circuit. At the same time the electromagnet is energized, thus causing the member 44 to be rotated by the crank pin to bring the gap 57 opposite the contact 45 and so to break the welding circuit after the desired interval. The electromagnet remains energized until the foot switch is released. The spindle of the member 44 is mounted at one side in a bracket 47 and at the other side in a slidable hollow rod 48 provided with a disc 51 and knob 50. A spring 53 separates the members 44, 51 and also resets the member 44, which has a stop 54 adapted to engage a stop 52 on the disc 51. In order to vary the duration of the current, the disc 51 has a series of holes 61 engageable with a peg 62 on the bracket 49 supporting the rod 48. Adjustment is effected by pushing forward and then rotating the rod 48 to required position, the rod being returned by the spring 53. Specification 397,157 is referred to.

Title: Improvements in or relating to the prevention of lateral splash by the wheels of vehicles
IPC: B60S1/62
Filed: 1926-12-31
Abstract: 284,446. Gowler, S. Dec. 31, 1926. Sand, distributing on wheel tracks. - Relates to means for preventing lateral splashing by vehicle wheels, in which currents of air are directed, across the paths of the splashes, from nozzles connected by piping to a blower &c. driven from a suitable part of the vehicle. The air currents may be utilized to distribute sand on the wheel tracks. To prevent the nozzles 27 from being damaged by kerbstones &c. they are arranged within the concavities of the wheels, as shown in Fig. 3, the nozzles being curved to direct the air currents outside the wheel rims and tyres. The shaft 8 of the blower 1 may carry fast and loose pulleys 7, 6 for engagement by a belt 5 driven from a pulley 4 on the transmission shaft 3 of a motor vehicle, the belt being moved from the pulley 7 to the pulley 6 by a fork carried on a bell-crank lever 10 operated by Bowden mechanism 14. A spring 12 tends to keep the belt on the loose pulley 6. The blower is connected to a receiver 16 connected to the nozzles 27 at the front and rear of the vehicle by pipes 20 - - 23, 37, 38. The nozzles for the steering wheels 29 are connected to the pipes 37, 38 by flexible tubing 40 carried by sets of arms 42, 45 fixed to the stub-axles 43. Each outer arm 45 is formed with a boss 46 having serrations held in engagement with a serrated boss on the corresponding inner arm 42 by a bolt 48 so that the outer arm may be swung upwardly and held in a raised position when it is desired to change a wheel. The nozzles of the rear wheels are mounted on similarly-arranged arms carried by brackets 31 fixed on the vehicle frame. Sand may be fed into the receiver 16 from a box 50 having an outlet controlled by a valve operated by a lever 54, spring 55 and Bowden mechanism 56. Instead of providing the blower with a disconnectable drive, the passage of air from the blower to the nozzles may be controlled by cocks.

A marine jet propulsion unit 13, Fig. 2, fixed to the transom of a boat comprises an axial flow impeller 22 which draws water from a bifurcated scoop nozzle 35A through ducting of gradually increasing cross-section ending in an annular opening 36A (see also Fig. 10), and discharges it through a removable nozzle 51. The axis of the nozzle is inclined to the horizontal so that as it is rotated about this axis, by ring gear and pinion 61, the jet is deflected first to one side and then downwardly, Fig. 5, passing over chevroned vanes 58 which provide reverse propulsion. The arm 59 on which the vanes are mounted, pivots as the nozzle rotates, so that it does not drag in the water during forward propulsion. As an alternative, Fig. 11 (not shown), the rotational axis of the nozzle may be horizontal and axis of the nozzle orifice 52 inclined. A steering wheel, Figs. 7 and 8 (not shown), rotates the nozzle through a control rod 64 and a chain on which a marker is mounted to indicate the portion of the nozzle. A flap valve, Fig. 4 (not shown), is fitted in the base of the intake 41A to increase the intake area at low speed. A lubricating water pipe 46 feeds water to the bearing 32A, and a similar pipe may be used to supply cooling water to the engine 29. The unit may also be mounted inboard with the nozzle 51 protruding through the transom.
