Title: Improvements in or relating to machine guards
IPC: F16P3/04
Filed: 1949-09-22
Abstract: 694,097. Machinery guards. SOUTHWARK MANUFACTURING CO., Ltd., and ONIONS, S. A. Dec. 20, 1950 [Sept. 22, 1949], No. 24377/49. Class 80 (iv). A screen for a platen press or like machine having a continuously reciprocating platen or ram is normally locked in stationary guarding position but on operation of a twohanded control on the manually movable workpiece carrier the screen is opened and closed as the platen rises and falls. The screen 13, which may be of wire mesh, rods or a transparent sheet, is slidable in vertical guide posts 5. Channel members 17 are mounted on the screen and serve to guide rods 18 which are reciprocated in time with, but faster than, the platen 10 by means of interconnected slotted levers 25, 19, the fixed pivot of each lever 19 being adjustable. A bar 28 attached to the screen by a slotted connection 29. 30 is normally retained by a spring 32 in the position shown in Fig. 2 where the reciprocating rods 18 register with gaps in the bar so that normally the screen is at rest. Weighted latches 47 engage the bar, or catch plates secured thereto or to the screen, and retain the screen in the closed position. Simultaneous actuation of two Bowden cables 40a, 40b operated by spaced handles on the workpiece carrier 12, however, displaces the bar 28 to disengage the latches 47 and to press spring-loaded elements 35 against the rods 18 so that on the next upward movement of the rods the bar and screen are raised. An adjustable foot 53 determines the lowest position of the screen. Where the platen operates at a speed greater than the free falling speed of the screen the latter may be driven downwardly through yielding mechanism. In an alternative arrangement pivoted fingers mounted on the platen engage and raise the bar 28, this arrangement being more fully described in the Provisional Specification, which also describes a pawl and ratchet mechanism and, alternatively, a sliding bolt mechanism for locking the screen in its closed position.

Filed: 1975-05-12
Abstract: 1500004 Magnetrons ENGLISH ELECTRIC VALVE CO Ltd 12 May 1975 [4 June 1974] 24655/74 Heading H1D A resonant cavity vaccum tube is tuned by movement of a tuning member produced by electrostatic attraction between the member and an adjacent electrode to which a voltage may be applied. As described, a multi-cavity magnetron is tuned by movement of a diaphragm forming the outer wall of one of the cavities (6, Fig. 1, not shown) produced by the attraction of an adjacent electrode (7) mounted, in an evacuated enclosure, outside the magnetron wall. Other cavities of the magnetron may be similarly tuned; the diaphragm may form the outer wall of a cavity coupled to one of the magnetron cavities (Fig. 4, not shown); and the electrode may be coated with insulator to form a stop position for the diaphragm. In a coaxial magnetron (Fig. 5, not shown) the diaphragm may form the end wall (6) of the outer cavity (20). In an alternative arrangement, Fig. 3, the diaphragm produces movement of a member 14 relative to the pin 12 secured to one of the anode vanes, and two electrodes, 7A and 7B, are provided, between which an A.C. frequency controlling signal is applied, whereby the magnetron frequency may be caused to follow a complex waveform.

[Class 13] In an electric bell in which the contacts 27 and 30 are contained in a fluid-tight box 1, adjustment of the contacts is effected through a tube 39 extending from the box 1 and closed by a fluid-tight screw cap 41. The adjusting means consists of a rotatable rod 33 carrying a cam 32 which engages a leaf spring 42 carrying the contact 30 and the rod is held in position by a locking spring 37 engaging a toothed wheel 36. The magnet system comprises a coil 17 and a parallel core 18. The armature may be inside or outside the box 1 and in the latter case, as shown, the blade spring carrying the contact 27 extends through a hole in the box closed by a fluid-tight diaphragm into the path of a screw carried by the armature. When the armature is attracted, the screw flexes the spring and the diaphragm and separates the contacts. The gong 16, through. which the tube 39 may also extend, is fixed to a boss 15 on the box 1 which also has radial arms 7 carrying a ring 6 fitted with fixing lugs 8. Specification 552,489 is referred to.

Title: Improvements in and relating to navigation equipment
IPC: G01C21/00
Filed: 1964-06-15
Abstract: 1,067,766. Compasses. H. E. FLORY. Sept. 15, 1965 [June 15, 1964], No. 24781/64. Heading G1F. The deviation of a compass card or the like from a preset course is monitored, to enable the preset course to be steered, by an arrangement in which an alarm is operated if the deviation of the compass card does not change sign at least once within successive equal predetermined time intervals. A compass 1 is provided with means giving an output signal when the compass deviates by a predetermined amount in either direction  from the preset course. The deviation signal is applied to a bi-stable circuit 2 to change its state and thus cause a capacitor 3 to become charged. The capacitor is discharged through a resistance 6 at a controlled rate and when the voltage falls below a predetermined value an alarm light or bell 4 is operated by an alarm circuit 5. The bi-stable circuit 2 ensures that successive deviations of the compass must be on opposite sides of the preset course, otherwise the capacitor 3 will not be charged. Each output of the circuit 2 is connected to a relay 7 or 8 having a parallel capacitor 9 or 10. These capacitors delay operation of the relay so that on change of state of the circuit 2 there is a short period during which contacts 7a, 8a of both relays are closed allowing the capacitor 3 to be charged. The relays may also have contacts to operate indicator lamps to show the direction of the compass deviation. The compass deviation may be detected by use of a pair of photo-transistors energized by light shining through or reflected from the compass card.

Title: An improved manufacture of carbon disulfide
IPC: C01B31/26
Filed: 1946-08-20
Abstract: Carbon bisulphide is produced by passing sulphur vapour into one or more reaction zones containing fluidized carbon at a reactive temperature, e.g. 1400-1600 DEG  F., and separating and recovering the vaporized carbon bisulphide from the carbon.  As shown in the drawing, powdered coke is fed into a fluidizing chamber 5 into which air or other gas is admitted through a pipe 6.  The fluidized coke is passed through pipes 8 and 9 into a heating zone A of a reactor 1 and is supplied with air, preferably preheated at 11 and in amount insufficient for complete combustion of the coke but sufficient to burn a portion thereof and to heat the remainder to the temperature necessary for reaction, either in pipe 9 or in zone A, to which more air may be supplied from chamber 5 by pipe 7.  The mixture of fluidized coke and air is passed preferably beneath a grid 12a into zone A, which is separated from a reaction zone B by a septum 2, and then passed downwardly in turn to each grid separated section of the reaction zone by pipes 18a, 18b and 18c and dispersing plates to react with upwardly flowing sulphur vapour supplied through pipes <PICT:0620315/III/1> 15 and 16 and heated at 14 by gases leaving the reactor through a cyclone separator 12 and pipe 13.  Alternatively, hot fluidized coke may be fed into the separate sections of the reaction zone. Carbon bisulphide vapour is withdrawn through pipe 19, a dust collector 20 which returns coke dust to zone B and is condensed at 21 and collected in a reservoir 22.  The fluidized coke leaving the last section 18c is largely ash and is used in zone C to preheat air entering through pipe 23 and screen 24 and passing out through pipe 25, ash being finally removed through pipe 26.
