Title: Improvements relating to coal-fired heating units
IPC: F22B9/04
Filed: 1962-09-25
Abstract: 1,019,611. Underfed solid fuel stoves; air heating stoves. J. L. MARGETTS. Sept. 26, 1962 [Oct. 4, 1961], No. 36464/62. Headings F4S and F4W. The combustion chamber 13 of an underfed solid fuel stove is spaced from a casing 10 through which air to be heated is circulated by a fan 24. The fire-pot 35, mounted in the refractory bottom 17 of the combustion chamber, is connected by a duct 40 to a hopper 12 from which fuel is fed by a screw 42. Air from a blower 46 is fed to an enclosed space below the fire-pot 35 and to a downwardly directed jet 56 above the fire-pot. Openings 50 in the duct 40 allows some of the air to enter the fuel duct, to prevent smoke flowing back to the hopper 12. A part 34 of the feed screw of reduced diameter forms a plug of fuel in the duct and helps in reducing the back flow of smoke. Dampers 57, 58 regulate the flow of air to the jet 56 and the fire-pot 35 respectively. The outside surface of the combustion chamber has fins formed by channel members secured to it, and the lower part has a heat resistant lining 62. This lining 62 is of material of different heat expansion properties from the stove body so that it wrinkles in use to further protect the combustion chamber wall. A dust trap 67, Fig. 6, hinged so that it may be lifted to drip flue dust into the combustion chamber, is mounted on the wall to cover the flue outlet 65. In a modification, Fig. 7 (not shown), the feed screw drive and the fuel hopper are mounted on opposite sides of the combustion chamber.

Title: Improvements in and relating to control systems for a.c. generators
Inventor: BUE TROND
IPC: H02P9/10
Filed: 1968-07-31
Abstract: 1285875 Automatic voltage control C A PARSONS & CO Ltd 18 Aug 1969 [31 July 1968] 36631/68 Heading G3R [Also in Division H2] An A.C. generator, synchronized with a grid system, has its rotor excited by way of a thyristor bridge. Under fault conditions, the firing angles of the thyristor are automatically changed to reduce the rotor current to zero. In the system shown, under normal conditions the output voltage of the generator 1 is sensed by a regulator 6 which, through a controller 5 vanes the firing angles in the thyristor bridge 2 to adjust the current in the rotor winding 1a and keep the output voltage constant. When a fault occurs, the regulator 6 is over-ridden by a signal from a load angle sensor 7 until the fault is cleared.

Patent GB-1223049-A (GB)
Title: Fishing net echo sounding system
IPC: G01S15/96
Filed: 1968-08-01
Abstract: 1,223,049. Echo-sounding. FRIED KRUPP G.m.b.H. 1 Aug., 1968 [2 Aug., 1967], No. 36797/68. Heading H4D. An echo sounding system comprises a sounder for attachment to a fishing net, and an echo recorder and control apparatus for installation in a fishing vessel, the control apparatus providing for both short range and long range soundings to be recorded in a cyclic sequence wherein one range of sounding is recorded a plurality of times for each time the other range is recorded. In the Fig. 3 embodiment stylus 20 on driving belt 39 of chart recorder 36 engages contacts 21, 22 in its travel to provide voltage pulses which are shaped by Schmitt triggers 25, 26, trigger monostables 27, 28 and hence close magneticallyactuated switches 16, 17 alternately. These switches supply positive or negative voltage from source 18 or 19 via cable 4 and diode 13 or 14 to net-borne equipment 8, for actuating relay 11 to connect upward-sounding transducer 3 and downward-sounding transducer 2 alternately to the ship-borne equipment 9. Monostables 27, 28 also trigger impulse generator 48 (via gate circuits 27a, 28a) for pulsing transducer 2 or 3 via transformer 12. Echo signals are fed via gated amplifier 34 to the recording stylus. Downward-sounding echoes for e.g. the depth range 0-60 metres are recorded in chart region T1 and upward-sounding echoes for e.g. the range 0-40 metres in region T 2 . For periodic recording of upward-sounding echoes in the 0-4000 metre depth range (including water-surface echoes, to indicate net depth) in region T 7  of the chart, switch 63 is closed whereby counter 53 provides an output signal for every tenth input from contact 22. This output triggers monostables 54 and 57 and hence actuates speed regulator 58 for reducing the stylus drive speed to one tenth nornal. Counter-timer 49 with a "start" input 50, a "stop" input 51 and a "reset" input 52 provides a digital indication of net depth. Transducers 2 and 3 may be positioned respectively at the top and bottom of the net opening, so that the upward-sounding recording overlaps the downward-sounding recording by an amount representing the width of the opening. An echo-sounder on the ship may be used for sounding fish shoals below the ship and its indications may be recorded on the same chart as the net-borne echo-sounder or on a separate chart. The ranges T 1 , T 2  and T 7  and the net depth may be recorded on separate charts instead of a common chart.

Abstract: 771,072. Making, filling and closing containers. HESSER MASCHINENFABRIK AKT.-GES., F. Dec. 23, 1954 [Dec. 28, 1953], No. 37178/54. Classes 18 and 94(1). The machine makes paper or cardboard containers by folding blanks around travelling formers and feeds them to filling and closing mechanism, the various operations being effected while the blanks or containers are moving continuously through the machine at a constant rate. Paper passes from a roll 2 through gumming and feed rollers 3, 5 and 6 and is severed by a knife 7 into blanks Z which are fed forwardly by cooperating endless bands 8, 9, the latter carrying transverse spacing-bars 10 which align the blanks with horizontal formers 11 carried by an endless chain 36 passing over sprockets 14, 15. As each blank approaches the exit from the belts, it is held against the under-surface of a former by a mechanical gripper or suction applied through orifices in the former, and as the former moves around the sprocket 14 the sides of the blank are folded upwardly by one of a series of devices 16 mounted for vertical movement on a drum 37 rotatable with the sprocket. Each device 16 comprises a spring- loaded horizontal plate 38 and vertical side plates and is moved upwardly to effect the folding by a fixed cam ring 17 engaging a roller 18 thereon. The upstanding rear portion of the blank is then folded on to the upper surface of the former by a member 19 which is carried by a rotatable spindle 21 mounted for swinging movement on a central vertical shaft 20, and the forward portion is folded down by a fixed plate 22. The bottom of the sleeve thus formed is finally closed in known manner by oscillating and fixed folders 23, 24. As the formers 11 pass around the sprocket 15, they move into alignment with holders 26 carried by an endless conveyer 25. The holders are normally positioned vertically on the conveyer, but as each holder is aligned with a former, it is swung to a horizontal position and the container P carried by the former is transferred to the holder by means of compressed air supplied through ducts in the end of the former. The holder then resumes its vertical position and carries the container beneath a rotary filling device 29 of known construction and to folding-mechanism, also of known construction, which closes its mouth. The filled and closed containers are ejected downwardly from the holders on to a plate 30 rotating with the conveyer sprocket 28, and are then transferred by a guide 31 to a rotary conveyer 32 which carries them under spring-loaded plates (not shown) which secure the closure folds. The completed packages are finally discharged by a guide 33. In modifications, Figs. 5-7 (not shown), the rotary conveyer 32 is replaced by an endless belt and the formers 11 are positioned vertically on the conveyer 36, the containers being transferred upwardly or downwardly into holders carried by an endless conveyer located above or below the conveyer 36. In the former case, the holders are temporarily inverted for the reception of the containers.

Title: Improvements relating to buffer mechanisms
IPC: B60R19/34
Filed: 1962-10-02
Abstract: 1,021,646. Vehicle buffers; bumpers; railway stops. E. STEIN. Oct. 2, 1962 [Oct. 10, 1961], No. 37264/62. Headings B7J, B7L and B7T. [Also in Division F2] A buffer mechanism for use in association with a road vehicle bumper or for a rail vehicle comprises a first member adapted to be struck on impact and a relatively fixed second member adapted to be secured to the body to be protected by the buffer mechanism, the two members being coupled to each other via at least two frangible co-axial discs arranged in series, such that fracture of the discs is effected in succession. Fig. 1 shows a car bumper 1 which is coupled to a car frame 2 by a leaf-spring 3 and a frangible unit 4. When the bumper 1 is subjected to an impact load, a boss 6 formed on a rigid disc 5 secured to the bumper is driven into the cavity 7 of an inverted cup member 8 of frangible material and as a result the circular wall of the cup fractures along the lines 8a, this fracture resulting in the dissipation of some of the kinetic energy of the impact. Depending on the magnitude and duration of the impact a pointed projection 18 on the base of the cup 8 is forced against the base 15 of the frangible member 14 and as a result the base 15 is also fractured along the line of incision 17. The disc 5 is coupled by means of a resilient sleeve 9 with a support member 10 at the end of the vehicle frame. As a result of this successive fracture a considerable amount of energy of impact is dissipated and prevents damage to the vehicle. Fig. 2 shows a railway buffer comprising a sleeve 21 which surrounds and is axially slidable with respect to an inner sleeve 22. Interposed between a closure member 23 of the sleeve 21 and a rod 25 is a helical spring 24 An end 26 of the rod 25 bears against a first frangible disc 28 so that when an impact is received by the closure member 23 of the sleeve 21 it causes firstly compression of the spring 24 resulting in movement of the outer sleeve 21 of the inner sleeve 22. After complete compression of the spring 24 the expended energy of impact causes a head 26 of the rod 25 to shear out the central portion of the first frangible disc 28 and in consequence the conical projection 29 of the disc 28 strikes in succession the central portion of a second frangible disc 34 with the consequent fracture of this second disc as well. This successive fracturing action is effective, in dissipating to a considerable extent the effect of the impact. The base 33 of the sleeve 22 is secured to a plate 35 which is either secured to a locomotive or railway car or to a fixed position at the terminal of a railway line.
