Title: Centrifugal apparatus for drying and pulverising manures and like purposes
Filed: 1932-08-02
Abstract: 405,039. Treating manures. HOAD, H. G., 77, Woodthorpe Road, Ashford, Middlesex, and WORTHINGTON, J., Willow Lodge, Arkley, Barnet, Hertfordshire. Aug. 2, 1932, No. 21701. [Class 111.] Poultry and like manures are treated in a centrifugal drum for extraction of moisture and granulating or pulverising the dried material thus produced. The drum d has its wall and bottom plate made of perforated plate or metal gauze and is mounted to rotate with the spindle c. A disc e, Fig. 2, from which segments e<1> have been cut, rests upon the bottom of the drum and is normally locked to it by a trigger f, Fig. 7, the trigger being held in place by a spring. A rod g at right angles to the spindle may be lowered into the drum to engage the trigger f, and to enable the scrapers i attached to its ends to remove material from the drum wall. The operation is effected by rack and pinion mechanism h. The under surface of the drum carries metal strips k which act as fan blades. Below these blades are arranged a screen m which revolves with the spindle c and a screen n fixed to the casing. The spindle is driven by the motor b; the scrapers i are raised to their uppermost position and the material is fed into the drum. The moisture passes through the drum wall and is prevented from reaching the solid materials in the discharge shoot by the flanges o<1>. The material in the drum becomes partly pulverised by its rotation in the drum as it becomes dried. A further pulverising effect may be obtained by arresting the rotation of the inner disc e by lowering the scrapers i and bar g until the latter engages the tail of the trigger f and releases its head from the bottom of the drum. The disc then. acts as a cutter while the material passes through the apertures. The material is further dried and pulverised by the fan blades k, and the screens m, n; it then falls upon the deflecting plate and passes to the discharge outlet. The drum may be removed from the spindle and replaced by a drum with a number of radial partitions having different sizes of mesh, or partitions r as shown in Fig. 9 may be attached to the drum d, for the purpose of drying feathers which are then graded by passing through the various partitions. For further use upon a poultry farm, a drum s, Fig. 10, is provided for mixing mash and like food material. This drum has a trap t which can be raised by chains u to discharge the mixed material.

Title: Improvements in frequency modulation radio receivers
IPC: H03J7/30
Filed: 1955-07-28
Abstract: 784,760. Stop-on-signal receivers. GENERAL MOTORS CORPORATION. July 28, 1955 [Aug. 18, 1954], No. 21818/55. Class 40 (5). A frequency modulation radio receiver having a tuner arranged to scan a frequency band and to be automatically stopped on receipt of a signal, comprises a condenser arranged to discharge through a relay coil when the signal is tuned in so that the relay operates and causes the tuning motor to stop. Momentary operation of a button 80 causes a flux latched relay 70 to operate. This removes a brake 74 from the tuning motor 126 and earths the control line foi the A.F.C. circuit 26. The output from the discriminator 20 of the receiver is applied through resistor 98 and rf. by-pass capacitor 102 to a valve 50. As the tuning approaches a station the voltage on the line 96 first goes negative whereupon the small standing current in valve 50 is cut off and a capacitor 116 is charged from the H.T. supply. As the tuning continues, the voltage on line 96 decreases to zero and becomes slightly positive, whereupon the valve 50 becomes conductive and capacitor 116 discharges through relay winding 68, reapplying the brake and removing the short circuit from the A.F.C. circuit. Reference has been directed by the Comptroller to Specification 649,537.
