Title: Improvements in or relating to variable speed transmission apparatus and the controlmechanism therefor
Inventor: GATISS ALBERT LESLIE
IPC: F16H47/08
Filed: 1953-12-10
Abstract: 750,455. Controlling change-speed gearing. BROCKHOUSE ENGINEERING (SOUTHPORT), Ltd. Dec. 9, 1954 [Dec. 10, 1953], No. 34342/53. Class 80(2) Change-speed gearing comprising an engine-driven hydraulic torque converter in series with an epicyclic gear train, a fluid-pressure-engaged clutch between the reaction or output member of the train and the impeller or turbine element of the converter for high-speed drive, and a fluidpressure-engaged brake acting on the reaction member of the train for low-speed drive, is controlled by a piston valve 11 normally held by a spring 14 in its lefthand position (as shown) in which fluid passes from an inlet 15 through a passage 17 to engage the clutch while the brake is exhausted, the valve being movable to its right-hand position, in which fluid passes from the inlet 15 through passages 22, 23 to the brake-engaging means 24 while the clutch is exhausted, both by a lever 19, upon energization of a solenoid 20 by the closing of a switch by an output-speed governor, and by a manually-operable lever 36, and the flow of fluid to the brake is restricted sc as to ensure that the clutch is fully disengaged before the brake is engaged. This restriction is provided by a valve element 29 slidable in the passage 23 under the influence of the fluid pressures, the element 29 having a central bleed orifice 30 and co-operating with a centrally-apertured seating 31. When valve 11 is in low-speed position, element 29 moves against the seating 31 and fluid can pass to the brake only through the orifice 30, while when valve 11 moves to highspeed position the element 29 moves away from the seating and fluid can exhaust freely from the brake around the element 29. The governor is controlled jointly by output speed and throttle opening, increase of speed tending to open the switch and increase of throttle opening tending to close the switch. A switch arranged in parallel with the governor switch may be closed manually for low-speed, or whenever the accelerator is fully depressed; Specifications 639,675, 702,838. 702,839 and 702,840 are referred to.

Filed: 1946-11-21
Abstract: 627,266. Spray-producers. THERMO PROJECTS, Inc. Nov. 21, 1946, No. 34563. Convention date, Aug. 8. [Class 69 (iii)] In apparatus for applying to selected areas insecticides and other substances the formulation is atomized mechanically and then introduced into a blast of heated air which further reduces the size of the particles. An applicator has a fuel tank 12 mounted on a base, fuel being supplied to the tank through a reservoir 13. Fuel is withdrawn from the tank through line 16 by pump 17, from whence it is fed to an internal combustion engine 26 and to a combustion chamber 34 through a control valve 40. The engine 26 drives a blower 32 which forces air through a duct 33 into the lower end of the chamber 34. The chamber is fitted with a plurality of metallic frustroconical bands 36 spaced from the inner wall of the outer shell to provide an annular air space 37 into one end of which the duct 33 discharges. Fuel is conducted through the valve 40 into the combustion chamber and ignited by a spark plug 41 to which current is supplied by a magneto 43. Hot air from the combustion chamber passes through a duct 46 into an atomizer 47 to which the formulation is supplied through a pipe 48. The pipe 48 has a plurality of radially disposed outlets 51 ejecting the formulation into an atomizing cup 52. The formulation is atomized by means of the hot air introduced into cup 52 through a series of tangentially disposed air holes 53 so that the atomized formulation is discharged radially from the cup 52. Hot air also passes out of annular openings 55 parallel to the axis of the cup so as to direct the jet and split it up into minute particles; whose size may be varied according to the rate of flow of the formulation and the quantity, pressure and temperature of the hot air. The duct 46 has three sections connected so that the section 58 is capable of universal movement. Locking means are provided consisting of a'U-shaped latch having legs engageable with teeth on the corresponding stationary section. The formulation is derived from a container 78 through a pipe 80 (Fig. 7, not shown), by means of a pump 82. The pressure of the flowing material is controlled by a pressure control valve 88 in a pipe 89 which provides a return to the container for excess material. A safety valve 92 is also provided. The pipe 89 feeds a pipe 91 (Fig. 7, not shown), the lower end of which projects into the container and discharges so as to keep the formulation in the container in continuous rotation.

Patent GB-1124909-A (GB)
Title: Process for roasting iron sulfide materials
IPC: C22B1/10
Filed: 1965-11-08
Abstract: Iron sulphide ores containing arsenic lead and antimony, are roasted in a fluidized bed such that substantially no elementary sulphur is produced in the roaster gas, the reaction conditions being such that the temperature and log of the oxygen partial pressure are below curve 1 (Fig. 1).  Preferably the conditions of temperature and partial pressure are maintained within the upper portion of the region defined by curves II and III (Fig. 1).  The hematite or other oxide cinders so produced may be mixed with iron sulphide material and charged into the bed in a dry or humid state.  Dust-like cinders are separated from the SO2-containing roaster gases and may be agglomerated before recirculation to the bed.  Elementary sulphur that may form due to irregularities in roasting, may be combusted by injecting oxygen into the roater gas.  Some of the oxygen for the sulphide combustion may be supplied through the bed and the remainder into the shaft, whereby roasting may occur in the shaft, at a higher temperature than in the bed.

Abstract: 836,355. Weighing apparatus. CHARROLD Ltd. Dec. 7, 1956 [Dec. 8, 1955], No. 35259/55. Class 143 When a carrier bar 5 or other support for a container to be filled with material is pushed into position on a weighing machine it automatically moves a catch 7 into a position in which it retains the bar 5 until a predetermined weight of material has been supplied to the container. In the construction illustrated the weighing scale, when it falls after the proper weight of material has been delivered, closes contacts 17, 18 in the circuit of a solenoid 14 which turns a lever 12 about its pivot 13 so that a link 9 pivoted to the lever 12 withdraws the catch 7 immediately before the lever 12 pushes the bar 5 over the depressed catch 7. The pivot 13 for the lever 12 is sufficiently loose to permit full retraction of the catch 7 before the lever 12 pushes the arm 5; the lower end of the link 9 is supported by a roller 11 engaging a cam track 16. When the bar 5 on a further container is pushed to position illustrated it turns the lever 12 about its pivot 13 to restore the catch 7 to its locking position. A time delay may be associated with the solenoid 14. The invention may be employed in conjunction with apparatus on a vehicle for filling sacks with coal, the sacks being supported on a platform depending from the bar 5. Specifications 643,588, 691,129 and 722,051 are referred to.

Filed: 1966-08-09
Abstract: 1,178,398. Valves. MARTONAIR Ltd. 9 Aug., 1967 [9 Aug., 1966], No. 35557/66. Heading F2V. A fluid control valve 6 is biased by a spring 8 to close port 2 and allow communication between ports 3 and 4. Actuation of solenoid 7 moves the valve to the position shown closing port 3 and allowing communication between ports 2 and 4 and the valve will remain in this position due to the fluid pressure differential thereon being greater than the spring returning force even when the solenoid is de-energized. An increase in pressure at port 3 by a solenoid actuated valve will move the valve to close port 2 where it will remain until the solenoid 7 is re-energized. A movable permanent magnet can replace the solenoid or the valve member can be an electromagnet or permanent magnet which is actuated by a movable piece of magnetic material.

Title: Improvements in and relating to apparatus for reading patterns and manipulating the punches for cutting jacquard cards for lace and other weaving
IPC: D03C17/00
Filed: 1920-04-01
Abstract: 164,680. Frame, A. April 1, 1920. Cards, punching. - Relates to the machines described in Specifications 17044/92 and 162,512, and comprises improvements in the construction of the cross needles, and in the means for returning them to their normal positions after they have been actuated. The cross needles D, Fig. 9, have ends bent backwards and made with notches d which engage with the slotted plate J forming one side of the needle box 14. Their other ends have preferably ferrules d<1> and there is in each an intermediate notch in which rests the corresponding string or draw needle E. The movement of a selection of the cross needles by the operator causes the corresponding hooked ends of the needles E to be moved in the way of the bars of the grid G, or, in a modification, to be moved out of the way of these bars. In order to return the cross needles D to their normal positions, a vertical plate or " splash board " 12 is fitted behind the needle box 14. It is slidably mounted on bolts 13, and pressed backwards by springs 13<a>. It is pressed forwards, so as to act on the ends of the needles D, by arms 18 on a vertical spindle 16 which is rotated either by a handle 27<a> or automatically by the reciprocation of the plate I which moves the string needles E and consequently controls the punches. This plate is moved by rods 27, and carries a spring catch 21 with a notch 22 which, as the plate I moves to the right, engages with the end of a lever 17 on the spindle 16, and forces inwards the plate 12. The free end of the arm 21 them engages with a pin 24 on the frame A, which frees the lever 17 from the notch 22, and enables the springs 13<a> to return the plate 12 to its outer position. In an automatic machine, the spring catch 21 is attached to an arm which moves the grid G and devices controlling the punches; in this modification, to enable a punching to be repeated as often as necessary, the gird G may be retained in position by manually-operated catches which engage with the sliding rods A carrying the needle box 14.
