Title: Improvements in fluid-tight means for distillation retorts
IPC: C10B1/04
Filed: 1945-03-10
Abstract: 600,266. Retorts for destructive distillation. SOC. ANON. LOUVROIL-MONTBARD-ALTLNOYE. March 10, 1945, No. 6177. Convention date, April 28, 1942. [Class 55(i)] In retorts for distilling solid fuels such as coals and schists charged at the top of a shaft 1 and discharged at the bottom, means are provided for controlling the operation of an extractor 12 for the vapours evolved to equalize pressures on both sides of a closure 3 at the charging end and ensure atmospheric pressure in the retort, and also for regulating the pressure in a chamber beyond a closure 10 at the discharging end so as to equal that in the retort at that end. For controlling the effect of pump 12 a valve 11 is operated by means of a governor 13 in dependence on the pressure in the upper part of the retort. For regulating pressure in the chamber beyond the retort a small amount of steam may be injected sufficient to pass through the closure into the retort, or a fan may be operated in dependence on the pressure difference between the lower retort zone and the chamber. Or a hearth chamber 21 in which the discharged fuel is burnt has an air inlet 22 operated in dependence on the pressure difference between retort and hearth. In another modification steam to be supplied to the lower part of the retort is heated by contact with the discharged schist before introduction at a pressure equal to that of the retort gases.

Title: Improvements relating to heat recuperators
IPC: F28D7/10
Filed: 1958-02-26
Abstract: 834,156. Furnace recuperators. ESCHER, H. Feb. 26, 1958 [April 12, 1957], No. 6193/58. Class 64(1) In a combustion furnace recuperator, air or other gas is heated in flowing through an annular jacket surrounding a conduit 1 through which hot gases from a furnace 3 are passed. Hollow fins extend from the conduit 1 into the heating gas stream and a proportion of the air or gas to be heated is directed through these hollow fins whilst the remainder flows through the jacket, the two streams being reunited in the lower and unfinned portion of the jacket surrounding the lower and mainly radiant heating zone 12 of the heating gas conduit 1. In the upper and coolest zone 14 of the conduit 1 where heating is mainly by convection, a guide tube 23 is provided, the upper end of which is closable by a valve 25. The valve 25 is constructed for simultaneous operation with a valve or cover 5 at the outlet end of conduit 1. Under conditions of maximum flow of the heating gas both valves are open and some of the gas flows through the guide tube which then heats the fins and conduit 1 by radiation. Under a partial loading, when the flue gases are relatively cool, the valves are lowered so that the valve 25 is closed. Hot gases are then directed in the zone 14 only through the space between the guide tube and the conduit 1 before passing to waste. Whirler vanes 26 may be provided at the gas entry end of guide tube 23.

Title: Sheet feed control device
IPC: B65H7/18
Filed: 1960-02-25
Abstract: 905,918. Sheet separators. MILLER PRINTING MACHINERY CO. Feb. 25, 1960 [March 6, 1959], No. 6630/60. Class 100 (1). Control apparatus for a sheet feeder comprises a cyclically operable separating means movable into and out of contact with a pile of sheets to separate sheets one by one from the top of the pile, the separating means being actuated by one portion of an operating member having another portion connected to continuouslyoperable driving means, and manually operable means to vary the cycle of the separating means so that separation of the sheets is prevented, the manually operable means being located remote from and at all times out of direct contact with the separating means and being operable while the driving means continue to operate. As shown, a number of sheet-separating devices 4 each having a suction foot 5 is mounted for vertical reciprocation in guides 55 of a supporting structure 56, the feet 5 being thereby moved towards and away from a pile of sheets 3 on a pile support 2. Each device 4 is biased downwards by a spring 58 and is connected with a source of suction by a pipe 70. A bell-crank lever 62, pivoted at 6, engages by means of a fork 60 at one end thereof a pin 59 projecting from a collar 57 mounted on each device 4. The bell-crank levers are oscillated by means of continuously-driven cams 69 which engage follower rollers 68 mounted on the bellcrank levers. A detent 15 is secured to a shaft 12 adjacent to each bell-crank lever 62 and is movable by rotation of the shaft between positions in which it does and does not engage a laterally projecting portion 63a of the bell-crank lever, such engagement preventing oscillation of the bell-crank lever and thus vertical reciprocation of the associated device 4 while the cam 69 continues to rotate. An arm 12a is fixed to the shaft 12 at one end and at the other is pivoted to a bar 8 which is vertically slidable in a guide 7 carried by the structure 56 and which is spring-biased downwards. The bar 8 has a foot 9 which engages the top of a horizontal bar 17. The bar 17 is formed with slots 18 which engage over studs 16 on the supporting structure, and is biased towards the left by a spring 19 which is more powerful than the spring biasing the bar 8 downwards. The bar 17 is normally held in the chain line position by an eccentric 24 mounted on a shaft 22, in which position the detent 15 does not engage the portion 63a. In order to interrupt the separation of sheets the operator moves the eccentric 24 to the full-line position by means of a hand-crank on the shaft 22, whereby the bar 17 moves upwards and to the left, thus urging the bar 8 upwards and the detent 15 into engagement with the portion 63a. Separation is resumed when the eccentric 24 is moved back to the chain-line position. The detent 15 can be engaged with and disengaged from the portion 63a only when the cam follower 68 is in engagement with the high portion of the cam 69.

Title: Improvements in or relating to regulators for electric power supply systems
IPC: H02J7/24
Filed: 1959-02-27
Abstract: 882,916. Automatic voltage control systems. GENERAL MOTORS CORPORATION. Feb. 27, 1959 [March 10, 1958; Aug. 22, 1958], No. 6892/59. Class 38 (4). In a voltage control system for a generator, adapted to supply a direct current and having output leads and a control winding, the energization of the control winding is controlled by a transistor having a base electrode connected to an output lead through the contacts of a relay having an actuator coil connected across the output leads. As shown, a three-phase alternator 100 and a rectifier 110 supplies a direct-current to a battery 128 through a supply lead 120a. The current through a field winding 104 of the alternator is controlled by a series transistor 122, the base to collector voltage of which is determined by a vibrating-contact relay 142 having an actuator coil 144. For an output voltage below the desired value, the relay contacts 148, 150 are closed and the base voltage of the transistor is that of the collector so that the field current is a maximum. At an high output voltage the contacts are open and the field current is determined by a resistor 132. The system alternates between these two states so as to maintain the battery voltage constant. An accelerator coil 146 of the relay is energized when the relay contacts are closed and sets up a flux assisting that of the actuator coil 144. The alternator 100 and rectifier 110 may be replaced by a shunt-excited generator. In a modification, the accelerator coil, in series with a resistor, is connected between the supply lead 120a and the base of the transistor 122, which is stated to improve the response of the regulator. The field 104 of the alternator 100 is rotated by a vehicle engine 106.
