Title: Improvements in method and means for steam heating
IPC: F24D19/10
Filed: 1927-12-05
Abstract: 307,376. Jackson, L. Mellersh-, (Warren Webster & Co.). Dec. 5, 1927, Heating buildings; thermo.stats.-Heating medium, such as steam, is supplied to radiators 1 through restricted orifices 4 which control the distribution to the system, the supply to the whole system being controlled by a valve 6, of which the maximum opening is adjusted manually by means of a counterweight 11, and the subsequent adjustment is effected automatically under control of a thermostat 18, outside the building, in such a way as to maintain a uniform temperature within. In the arrangement shown, the thermostat comprises a thermometric tube in which is a resistance wire 19, more or less of which is short-circuited according to the height of the mercury. The wire 19 is in the electric circuit of a solenoid, the core 15 of which is attached to a spring-suspended rod 21 carrying a contact finger 22 moving over a resistance 26 in the circuit of a solenoid 13, the core 12 of which is connected to the balance lever 9 of the valve 6. The outside temperature thus controls the vertical movement of the rod 21 and contact finger 22, and hence, through variation of the resistance 26 in the circuit of the solenoid 13, the valve 6. Means are also embodied for reducing or cutting off the supply of heating medium during certain periods, such as at night, comprising a clock 31, the hour hand of which moves over contact pins set, in the case shown, at the hour divisions between 1 and 8 a.m. and 4 and 11 p.m. These pins are connected by conductors 35 and 38<1> to corresponding contacts on vertical bars 36, 38, over which move contact fingers 40, 41 carried by the vertically-movable bar 21. The fingers 40, 41 are in the circuits of solenoids 44, 45 respectively, which operate a switch arm 46. The switch 46, when moved to the right, closes a shunt circuit 54, connected to a contact finger 55 which .cuts out the portion of the resistance 26 between it and the finger 22, and so increases the current through the solenoid 13 and causes further closure of the valve 6. This closing movement occurs at some period between the hours of 4 and 11 p.m., during which the contacts of the clock 31 come into operation, the exact hour being under the control of the thermostat 18, which adjusts the vertical position of the contact finger 41 through which the closing circuit is completed. In a similar manner the switch 46 is moved to the left to open the shunt circuit 54 and restore normal heating when simultaneous contacts are made, between the hours of I and 8 a.m., at the clock and at the contact finger 40. At the position shown of the parts, reduced heating will be initiated at 7 p.m. and full heating restored at 5 a.m. A rise in outside temperature, causing a lowering of the contacts 40, 41, advances the hour of closure of the closing circuit and retards that of the circuits which restore normal heating, a fall in outside temperature having the reverse effects.

A gas turbine jet engine of the by-pass type comprises at the entry of the by-pass duct into the exhaust pipe, an exhaust pipe section with circumferentially-spaced openings, and a chutering co-axially disposed within the exhaust pipe and having radially-inwardly-extending chutes which promote mixing of the by-pass air and exhaust gas flows. The shoot ring is movable axially with respect to the exhaust pipe so as to throttle the by-pass air flow by variably obstructing the chutes. The invention is described with reference to a two-spool type engine, the turbine exhaust passage being indicated at 22 and the downstream end of the by-pass air duct at 31 in Fig. 2, the turbine exhaust passage being defined by sections 26 and 27 which are interconnected by a section 35, while the by-pass duct is defined by an outer wall 10. The section 35 is formed with a number of openings 41 through which by-pass air flows to mix with the turbine exhaust gases in the duct 22, there being ten such openings in the present embodiment. The section 35 is also formed with a frustoconical portion 37 which co-operates with the downstream end of the wall 10, a piston ring element 38 carried by the portion 37 engaging with the cylindrical surface 39 of the wall 10 to provide a seal. An axially-movable member 45 is disposed within the duct section 35, the member being formed with chutes 46 each of which co-operates with an opening 41 in the section 35 so as to guide the inflowing by-pass air. The member 45 is shown in its forward position in full lines and in its rearward position in which it restricts the flow area of the openings 41 in chain-dotted lines. The member 45 carries pairs of rollers 55 which engage within channel section members 53 which extend longitudinally of the duct section 35. The member 45 also carries a pair of brackets 58 which are connected by links 66 to the rods 65 of hydraulic or other actuators 57 whereby the axial position of the chute member may be controlled. The engine may alternatively be a gas turbine propeller engine.

Title: Improvements in and relating to sliver evening mechanisms for carding machines
IPC: D01G15/36
Filed: 1921-12-13
Abstract: 194,017. Harrop, W. Dec. 13, 1921. Carding-engines; feeding carding-engines. - To ensure a uniform sliver in restarting after stripping the cylinder, the speed of the feed roller is automatically increased for a predetermined time, and is then automatically reduced to normal, these operations being effected by the opening and closing of the door. When the door G is opened, the feed shaft 15 is shifted laterally to disconnect the bevel drive from the low gear 12 on the doffer shaft c and the wheel 17 is shifted longitudinally ready to engage the high gear 11. When the door is closed, the shaft 15 is returned laterally and remains in high gear until a shipper rod 31 is released by ratchet mechanism and a spring 55 then shifts the bevel drive into low gear. The door G carries a plate 23<a> which is connected by a link 24 and a lever 25 to an eccentric bush 19 carrying the shaft 15; the door also has a tail-piece pivoted at 36 to a tube 34 telescoping over a rod 33 pivoted to the shipper rod 31. Thus on opening the door, the eccentric bush 19 shifts the shafts laterally and disconnects the gears 12, 13, and the shipper rod is pulled to compress the spring 55 and slide the wheel 17 longitudinally ready for the high gear. The rod 31 is locked in this position by a shoulder 54 engaging the lower edge of an aperture 53 in a fixed plate 42. When the door is closed, the eccentric bush 19 is oscillated and brings the gears 11, 14 into engagement, and the tube 34 merely slides up the rod 33. On restarting the machine, the shaft 15 rotates at the higher speed for an interval which is governed by the ratchet wheel 43. This wheel is driven by a pawl 48 from an eccentric 44 on the shaft 15 and is locked by a weighted dog 50. The rotation of the wheel 43 winds up a weight 64. An adjustable pin 61 on the plate 42 indicates zero position of the ratchet wheel, and an adjustable pin 60 on the wheel is carried round and releases the shoulder 54 of the shipper rod 31 from the plate 42. The wheel 17 is then returned by the spring 55 into low gear 12. 13, and simultaneously a notched bar 66 attached to the rod 31 is pulled through a slot 67 and lifts the pawl 48 and dog 50 from the ratchet wheel, which is then returned to zero position by the weight.
