Title: Improvements in ventilating system
IPC: F24F7/10
Filed: 1936-11-24
Abstract: 489,424. Ventilating rooms and other enclosures. BURGESS LABORATORIES, Inc., C. F. Nov. 24, 1936, Nos. 32188 and 32189. Convention dates, Feb. 4 and Aug. 14. [Classes 20 (iv) and 137] In the ventilation of enclosures such as rooms, churches, road or rail vehicles, and aeroplanes, the air is supplied through foraminous sheets spaced from a wall or ceiling, and having an air-impervious backing the extent of which is adjusted so that slight pressure from a conditioned air supply is built up in a plenum chamber between the foraminous sheets and the wall. The ceiling 19 is traversed by bolts 20 suspending beams 18 to which are attached strips 21 holding the foraminous layer of perforated tiles 23. Within each tile is a panel or backing 24 of sound absorbing material such as wood fibre or felt having a covering of air-impervious material, the panels being spaced from the tiles. Ventilating air is supplied by a conduit 31 to the space 38 above the foraminous layer through which the air percolates, and enters the room without draught, the used air being exhausted through grilles 35 near the floor level. A duct 27 brings the outside air to a conditioning unit 28 which operates in conjunction with a refrigerator 29, or heater 32 a fan 30 supplying the conditioned air to the delivery conduit 31, which is lined near its delivery end with sound absorbing material 33 faced with foraminous smooth surfaced material 34. In a modification, the air may be supplied to hollow beams which support the foraminous tiles and which have openings in their upper parts to allow of circulation of the air over the tiles. The ventilating air may be heated or cooled by the use of pipes 67, Fig. 7, in which circulate heating or cooling fluid, these pipes being embedded in the concrete ceiling 65. The foraminous tiles 70 are supported below sound absorbing panels 79, and a fan 76 draws up air from the room and discharges it into the plenum chamber 77 under a pressure which forces it through the tiles. In Fig. 11, a blower 10 draws air through an intake 12, and supplies it under pressure to a plenum chamber 14 between the roof 18 of a vehicle and an apertured member 16, below which is a second ceiling or sheet 24 which causes a still further distribution of the air. Supporting beams 20 are apertured to allow passage of the ventilating air which may be conditioned before use. Another modification describes the ventilation, in a similar manner, of a railway car. Specifications 327,186, [Class 20 (iv)], and 489,423 are referred to.

Title: Tubular heaters
Inventor: BECKER HAROLD ARTHUR
IPC: C10G9/20
Filed: 1954-11-08
Abstract: In a tubular heater, for heating petroleum oils and other fluids, which is enclosed within a vertical chamber having a refractory cylindrical wall, the lower portion of the chamber is divided into at least three radiant heating sections by vertical <PICT:0772894/III/1> <PICT:0772894/III/2> partitioning walls; burners are provided and arranged so that their flames flow over the faces of the partitioning walls, and a bank of tubes is disposed within each of the radiant-heating sections adjacent the cylindrical wall of the chamber.  The heater provides independent control of the intensity of heating within the separate radiant sections; and it may be used for heating a particular fluid stream in stages, or for simultaneously heating a plurality of independent fluid streams.  The lower portion of the cylindrical chamber 1 of the heater shown is divided into three sections 8, 9, 10 by partitioning walls 6 and 7.  Located in the floor 3 of the chamber are burner blocks 13, 14, 15, accommodating burners which project high-temperature flames upwards along the faces of the partitioning walls.  The radiant sections are provided, at the circular wall of the chamber, with separate banks 16, 17, 18, of vertically-disposed tubes connected by U-bends at their top and bottom extremities. In the apparatus shown, the tube-banks are connected in series; but arrangements are readily made for parallel flow through the radiant sections.  The combustion gases leaving the radiant sections pass to a common convection zone 11 in which is suspended a bank of tubes 21.  This convection tubebank may be used for heating an additional fluid stream, or it may be used for preheating one of the streams passing to the radiant sections. The combustion gases pass from the convection zone to the gas outlet 12. Reactor or conversion zones 26, 27, 28, may be located circumferentially around the furnace chamber.  The charge stream may be introduced through line 29 to radiant tube-bank 16, where it is heated to conversion temperature.  The stream then flows through line 30 into reactor 26.  The reduced-temperature stream discharged from reactor 26 is reheated in radiant tube-bank 17, and then introduced into reactor 27.  Similarly, the reduced-temperature stream discharged from reactor 27 is reheated in radiant tube-bank 18 before passing to reactor 28.

Filed: 1919-12-29
Abstract: 137,299. Wellman - Seaver Morgan Co., (Assignees of Rogers, J. F., and McClimon, J. S.). Dec. 30, 1918, [Convention date]. Charging.-An apparatus for feeding fuel to gas-producers of the rotary-bed type comprises a casing or shoot 10 open at top and bottom respectively to a fuel-bin and the producer, and having mounted therein a rotary pocketed valve 30 near the lower end, and above this a rotary measuring-device 20, the speed of rotation of which can be varied relativelv to that of the valve. The driving-mechanism consists of two ratchet and pawl gears 56, 60 operated simultaneously from a rock shaft 50, and to provide a variable speed drive for the measuring-device one end of the link 64 connecting the rock shaft and the pawl-plate 61 is pivoted to a block 65, which can be moved in the frame 66 towards or away from the axis of rotation of the shaft 50 bv a screw 67. A pointer 65<a> moving over a scale enables the feed to be set at any predetermined rate. The lower part 10<d> of the casing 10 is shaped to form a seat for the valve 30 and hall bearings for its shaft, the bearings being completed by yoke-pieces 39 bolted to the casing. The pockets in the valve are formed by radial partitions 34, from which extend flanges 38 in the direction opposite to that of rotation. A door 42 gives access to the interior of the casing 10, and yields to allow large pieces of fuel to pass the measuring-device.

Title: Electromagnetic relay circuits
IPC: H01G4/32
Filed: 1937-11-26
Abstract: 484,892. Electromagnetic relays. STANDARD TELEPHONES & CABLES, Ltd. Nov. 26, 1937, No. 32723. Convention date, Dec. 19, 1936. [Class 38 (v)] In a circuit arrangement in which a device such as a relay 1 is caused to respond after a time interval determined by the charging up of a condenser 13, the relay and condenser are connected respectively to the output and input terminals of a rectifier bridge 6, and, at the commencement of the operation the condenser is connected across a source of voltage. In the form shown, in which the relay 1 is of the polarized type, a biassing battery 3 normally causes a small current to pass the wrong way through the rectifier 6, the resulting slight energization of the relay holding its armature against the back contact as shown. The condenser 13 is uncharged, its opposite poles being connected to the negative poles of two batteries 16, 18 and therefore at the same potential. When a relay 2 is operated, a battery 19 is connected in series with the battery 16, a current flows through resistances 17 and 15 and the condenser 13 slowly charges up at a rate determined by the high resistance offered by a rectifier 14. An ever increasing potential difference is thus established across the points 11, 12 of the rectifier bridge 6 tending to send a current in opposition to the current from the battery 3 through the relay 1. When the potential difference exceeds the battery voltage, the relay 1 operates. When relay 2 releases, condenser 13 discharges quickly through rectifier 14 and relay 1 returns.

Abstract: 366,562. Slaughtering pistols. DUCHENET, J., Modern Garage, Belley, Ain, France. Nov. 1, 1930, No. 32946. [Class 28 (ii).] A safety slaughtering pistol is made with a cartridge chamber 12 in the rammer 10, the explosion of a blank cartridge therein causing the forward thrust of the rammer limited by a stop on the barrel, and the spent cartridge being simultaneously disintegrated and ejected. In the form shown in the Figure, the barrel 6 is slidably arranged in a carrier 3 hinged at 2 to a handle 1. A blank cartridge is loaded into the chamber 12 while the carrier 3 is open, then the carrier is closed over the handle 1 and looked by a spring catch 4. The barrel is then firmly secured to the handle by a bayonet joint 7. A hammer 31 is then cocked against its spring 32 until a trigger 33 engages with a bent 35 in the hammer. A deflection of the trigger by a finger releases the hammer, which strikes a firing-pin 29, thereby firing the cartridge. The rammer 10 fitted with a piston 9 is driven forward until arrested by a buffer against a stop 13, which is provided with a screwed stud 24 for securing the stop to the barrel in one of three positions according to the extent it is desired the rammer shall project beyond the barrel. The stud 24 slides in a slot 19 in the barrel and can be screwed down into one of three seats 20, 21, 22 in the barrel. When the rammer is thrust forward, the cartridge is disintegrated and ejected from the chamber 12, and the gases escape by holes in the barrel. A ring 36 is hinged to the endpiece 37 of the handle 1 for suspending the pistol. In a modification, the barrel is mounted in a carrier slidable on a tube on the handle 1, the tube being provided with lateral holes for the insertion of the cartridge.
