Title: An improved process and apparatus for the dry cooling of coke and the like
IPC: C10B39/02
Filed: 1929-02-22
Abstract: 327,819. Piette, O. Feb. 22, 1929. Cooling discharged materials. - In apparatus for cooling coke by the continuous circulation of inert gas through the coke and a steam - generator, the c o k e chamber is divided by partitions 6 into compartments 2 through which the gas passes in succession. Each compartment 2 is fitted with an inclined step-grate. 3 on to which the coke is delivered from a truck 1; the space between the grate 3 and the bottom of the chamber 2 is divided into two compartments 4, 5 and the side walls 6 are formed with oblique apertures connecting the upper compartments 5 of one chamber 2 with the lower compartment 4 of the adjacent chamber. The cooling gas is supplied by a fan 7 to the lower space 4 of the first chamber 2 and, after passing upwardly through the coke on the lower part of the grate 3 and then downwardly into the space 5, traverses the other chambers 2 in a similar manner. From the space 5 of the last chamber 2, the gas passes through a dust-chamber 11 and downwardly around the tubes of a steam-generator 12, a conduit 13 serving for the return of the gas to the fan 7.

Title: Improvements relating to the operation of projectors using film strip
IPC: G03B1/18
Filed: 1947-03-03
Abstract: 640,645. Combined sound and picture apparatus. VAUGHN, W. G. J. March 3, 1947, No. 6010. [Class 40 (ii)] [Also in Group XX] The frames of a film strip projector are changed automatically by signals derived from a recorded commentary. The signals may be specially recorded sine wave pulses, interruptions in a continuously-recorded sine wave, or voltage changes corresponding to deliberate pauses in the commentary. Alternatively in the case of disc recordings, the signals may be derived from switches actuated by the turntable drive or by the pick-up arm. The pick-up 1 is connected to an amplifier 2 which is connected to the loudspeaker 4 through a filter 3 which rejects the actuating signal frequency. The amplifier is also connected through a filter 6, which accepts the actuating signal frequency, to a relay 5 controlling the motor 7 driving the film feed of the projector (see Group XX). Cam-operated contacts 13 in parallel with relay 15 maintain the supply to the motor until the frame change has been completed. A switch 14 allows manual control. In a modification, Fig. 2 (not shown), the motor is connected with a manually-operable reversing switch.

Title: Pelleted seeds
IPC: A01C1/06
Filed: 1972-02-10
Abstract: 1376212 Coated seeds SAREA AG 10 Feb 1972 [10 Feb 1971] 6346/72 Heading A2Q The coating of pelleted seeds consists of an inner layer comprising a fungicide, a distinct outer layer comprising an insecticide, a layer comprising neutral pelleting material and a layer comprising a disintegrating agent. The disintegrating layer may be between the seed and the fungicide, and the pelleting material between the fungicide and the insecticide, and the latter may be glazed. Alternatively, the disintegrating and pelleting materials may be between the fungicide and insecticide layers or they may be combined with the fungicide layer. In a further arrangement the sequence of layers progressing outwardly from the seed is; pelleting material, fungicide, pelleting material, disintegrating agent, pelleting material, insecticide and glaze. The insecticide, which may be a chlorinated hydrocarbon, may be non-systemic or partially or chiefly systemic, and the fungicide may be a seed grain disinfectant, e.g. a mercury or copper-based fungicide, or a synthetic fungicide such as a dithiocarbamate. The disintegrating agent is one that undergoes decomposition and preferably envolves gases in the conditions prevailing in the soil &c. to break down the coating. Suitable agents are carbonates, bicarbonates, chromates, bromates, perchlorates, particularly sodium carbonate and bicarbonate and potassium bromate and chromate. The coatings may also include a swelling agent in the same coating as the disintegrating agent, fertilizers, growth promoting substances, hormones and colourants. The swelling agent may be of natural origin such as a vegetable hydrocolloid, an alginate, balsa wood flour, animal hair, or it may be a chemically modified natural substance e.g. a methylated cellulose, or it may be synthetic, e.g. a foamed vinyl or acrylate-based polymer. Each layer may be applied by dusting followed by spraying of a binder such as a solution of sugar, gum arabic, or starch.

Abstract: 978,222. Transistor switching circuits MITSUBISHI DENKI KABUSHIKI KAISHA. Feb. 24, 1961 [Feb. 26, 1960] No. 6813/61. Heading H3T. In a switching circuit comprising two or more transistors having their emitter-collector circuits in series and their bases connected to a common input-circuit, diodes are connected in one or more of the base connections to prevent reverse current flowing between the collector and the base input lead when the transistor is cut-off. In the Figure, a high voltage source 64 is connected to a load 66, which may be inductive, through three switching transistors connected in series and rendered non-conducting by opening a switch 70 connected to a bias supply 68. When the switch is open, diode 76 becomes non-conducting, so preventing the full voltage of the supply being applied across the collector-junction of transistor 16 through the common input circuit and the base emitter circuit of transistor 24. Diode 74 performs a similar function for transistor 14. In an alternative circuit (Fig. 1, not shown) the switch 70 is connected to the successive bases through rectifiers in series instead of in parallel. The base resistors may have different values so as to equalize the base currents, or may be omitted.
