Title: A combined furnace and gas turbine
IPC: F02C1/06
Filed: 1945-07-13
Abstract: 616,343. Gas-turbine plant. MASCHINENFABRIK OERLIKON. July 13, 1945, No. 17964. Convention date, Aug. 18, 1944. [Class 110 (iii)] [Also in Group XIII] In a combined furnace and gas turbine of the kind not comprising a steam-raising boiler, in which a portion of the heat of the furnace gases is given up to an external heat consumer without raising steam, a first portion of the exhaust gas of the turbine is used as combustion air in the furnace, a second portion of the exhaust gas is mixed with the combustion gases immediately above the combustion layer in the furnace and after this mixing the temperature of the combustion gases is lowered for the purpose of generating mechanical power and a third portion of the exhaust gases transmits its heat to any external heat consumer or is used to preheat the working fluid of the gas turbine. Air compressed in a compressor K is heated in two heaters L1, L2, by the furnace gases from a grate C which is used to give heat to an external heat consumer without raising steam. The heated air passes to a turbine M which drives the compressor K and a useful output generator N. The exhaust from the turbine M is divided into three parts. The first part is used at 60 as combustion air in the furnace, the second part passes through the pipes 59b, 59b<1> and is mixed with the combustion gases at 61 immediately above the combustion layer on the grate C and a third part passes through a pipe 59c to the air preheater L1 to preheat the working fluid of the gas turbine. The mixed combustion gases and turbine exhaust flow through 80 to the air heater L2. The gases flowing through the heater L2 may be abstracted at 81, mixed with further hot gases and another part of the turbine exhaust in a chamber 652 and returned to the heater at 82. The gases leaving the heater L2 pass through a portion of the heater L1 which is separate from that through which the turbine exhaust flows. This allows the turbine exhaust to be cooled to a lower temperature than the combustion gases. The turbine exhaust gases from the heater L1 may then be used in a heat exchanger B3 to give heat to an external heat consumer. Heat may be given to this consumer by the combustion gases exhausted from the heater L1 and by the portion of the turbine exhaust used as combustion air, in heat exchangers B1, B2. The turbine exhaust gases leaving the heat exchanger B3 may be expanded in a turbine M1, the exhaust temperature of which is so low that it produces a heat pump effect. If desired, a separate heat pump P, Q, R, S may be 'employed, the heat from which is used in a heat consumer H. The heat obtained from cooling the compressor K may also be used in the heat consumer H. Specification 569,441 is referred to.

Title: Bag filling and closing apparatus
IPC: B65B7/06
Filed: 1963-05-07
Abstract: 992,824. Filling and closing bags. CANADIAN INDUSTRIES Ltd. May 7, 1963 [May 14, 1962], No. 17985/63. Heading B8C. In a machine for filling and closing bags 1 the opposed top edges of a filled bag are tensioned into alignment by inserting a pair of pins 4, 5 into the open mouth of the bag to prepare it for closure, e.g. by seaming, stitching, or an adhesive. The machine illustrated comprises a filling hopper 2, closure device 23, and conveyer 3. Pneumatic cylinders 6, 7 carrying the pins 4, 5 are slidable on rods 8, 9 parallel to the conveyer 3 and are urged apart by unequal counterweights 10, 11 acting via cables 18, 19, the cylinder 7 being restrained from motion by the piston 21 of a pneumatic cylinder 22. In operation a bag 1 carried on the conveyer 3 between guides 12 is filled from the hopper before passing beneath the cylinders 6, 7 where it actuates a switch 30, which causes pins 4, 5 to be inserted into the bag mouth and the piston 21 to be withdrawn so that cylinder 7 slides and pin 5 contacts the leading edge of the bag. Further progress of the bag causes its rear edge to contact pin 4 which, with pin 5, tensions the opposed top edges of the bag into alignment under the action of the counterweights 10, 11. As the top edge of the bag is gripped by the intake chain 24 of the closure device 23, the cylinder 6 actuates a switch 31 which causes the pins to be withdrawn from the bag mouth and cylinders 6, 7 to return to their original positions. In modifications the counterweights may be replaced by springs, and the pneumatic cylinders by mechanical devices.

Title: Improvements in or relating to nuclear reactor installations
Inventor: HOSEGOOD SAMUEL BRITTAN
IPC: G21C1/22
Filed: 1957-06-06
Abstract: 829,958. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 16, 1958 [June 6, 1957], No. 17995/57. Class 39(4). A liquid-cooled or liquid-fuelled nuclear reactor 1 is associated with a liquid dump tank 5. The level of liquid 4 in the reactor is maintained by the pressure difference between an inert gas in the space 12 and in the space 13. The pressure difference and hence the liquid level are kept constant by connecting the reactor gas space to the low-pressure side and the tank gas space to the high-pressure side of a continually-running compressor 9 across which are connected in parallel a blow-off valve 10 and a dump valve 11. The blow-off valve maintains a constant pressure difference and its opening pressure controls the liquid level. When the dump valve is opened liquid is dumped into the tank ; when it is closed liquid is automatically pumped back to its original level. The pressure of the gas can be adjusted by means of an intermediate-pressure reservoir 16 and valves 14 and 15.

Title: Improvements in and relating to apparatus particularly applicable for the adjustmentof a distant continuous current motor
IPC: G05D3/12
Filed: 1920-07-02
Abstract: 145,728. Krupp Akt.-Ges., F. March 16, 1918, [Convention date]. Systems for controlling travel for a fixed distance or number of revolutions.-An arrangement for the control of a distant continuous-current motor operating a gun or search-light has a starting-device with a resistance connected across the continuous-current mains so as to secure a rotating fall of potential, and a pair of brushes rotated by the main motor and also connected electrically to the main motor brushes. The transmitter A is connected to an auxiliary motor B at the receiving station; the armature shaft b<1> of this motor carries a commutator connected to the resistance b<3> and rotating under brushes D, D', the brush-holder being rotated by the main motor E. Disks F, G with contacts as shown are geared to the auxiliary motor while the brushes H, H<1> and J, J<1> associated with the disks are geared to the motor E. The gearing ratios are adjusted so that one revolution of the disk F corresponds to several revolutions of the motor B and to a fraction of a revolution of the disk G. A complete revolution of the disk G corresponds to the entire range of adjustment of the transmitter A. When the transmitter A is rotated, the motor B moves the contacts of the resistance b<3> under the brushes D, D<1>. Current therefore flows from the mains through the brushes D, H, J, E<2>, the main motor armature E, and the brushes E<3>, J<1>, H<1>, D<1>. This motor commences to rotate and operates the brushes geared to it to follow up the resistance contacts and the disks F, G. As the movement of the transmitter continues the resistance contacts move ahead of their brushes until the brushes are connected directly to the mains. At the same time the brushes H, H<1> pass from the contacts f<1>, f<3> to f<2>, f<4>, thereby completing a circuit for the armature E through the leads f<5>, f<6>. When the rotation continues long enough for the contacts f<2>, f<4> to leave the brushes H<1>, H the motor circuit is transferred to the leads g<6>, g<5>, and the contacts g<2>, g<4> on the disk G. As the transmitter movement finishes, the brushes rotate faster than the disks until disks and brushes are in the same relative position as at the start; in this position the armature E is short-circuited by the brushes D, D<1> and quickly comes to rest. In a modification, the rotary resistance b<3> is replaced by a fixed circular resistance and four brushes, arranged ninety degrees apart, are attached to a single holder b<13>, Fig. 3, rotated by the motor B. The brushes b<10>, b<11> are connected together and the other pair are connected to the continuous-current mains. The gearing is shown in Fig. 3; the disks F, G are driven by worm gearing b<15>, b<16> and the brushes H, H<1>, J, J<1> are similarly driven by the motor E. The holder of the brushes D, D<1> is mounted directly on the main motor shaft.

Envelope blanks 16 fed in succession at high speed by pins 14 on conveyer chains 10 are stacked on a table 200 by a rotary transfer and stacking device B, such as that described in Specification 857,769, which includes wheels rotating at constant speed carrying blankholding means which move at the same speed as the wheels to take a blank, and then move at a lesser speed during the interval when the blank is released for stacking, each blank being arrested on release by alignment pins 208 or the like so that it is superposed on the stack. The blank-holding means on the wheels comprise suction grippers which can be rocked periodically in a direction contrary to the rotation of the wheels just before release of the blanks. The stacker table 200 is slidable along fixed posts 204, and has pins 212 engageable with chains 214 which are driven in the direction D by a stacker indexing mechanism 216 in synchronism with the shaft 22 on which the transfer wheels are secured. The stop-pins 208 are adjustably mounted on a baseplate, and pass through large holes in the table 200; they engage notches 210 at the sides of each blank to stop and locate the blank over the stack.

Title: Improvements in or relating to mine sweeping apparatus
IPC: B63G7/04
Filed: 1924-07-29
Abstract: 243,411. Elia, G. E., and Lucas, D. July 29, 1924. Sweeping mines.-A mine sweep is providÞd with a device comprising a float, a hook, and a gripper and cutter by means of which a minemooring cable is cut and the float is simultaneously attached to the part of the cable connected to the anchor. This enables the mine to rise and be recovered, and indicates the position of the anchor, which can also be recovered subsequently. As shown, the float q is normally held between two seats t, s, one s carried by a central member a and the other t by an arm b pivoted at d to the central member. Another arm c is pivoted at c to the central member, and the two arms b, c are locked by a bolt j and are connected by a rope m passing over a number of pulleys to the member n of a slip hook o. A hook v is secured' to the central member and is adapted to engage a mine-mooring cable when the device is towed by a mine sweeper attached by a rope x to the slip hook. The stress thus set up shears the bolt j, withdraws the slip hook o from the central member a, thereby detaching the device from the sweeper, and swings the two arms b, c against each other, thereby releasing the float and gripping the mooring cable between them. At the same time, cutters f, h at the ends of the arms cut the mooring cable, thereby freeing the mine and allowing it to rise to the surface, while the device remains attached to the part of the cable connected to the anchor, and its position and that of the anchor is indicated bv the float g, which rises but remains connected to the device.
