Title: Improvements in or relating to the drying of grass or the like
IPC: F26B11/18
Filed: 1936-06-20
Abstract: 477,279. Drying grass &c. KALOROIL BURNERS, Ltd., and GOLDBERG, A. June 20, 1936, Nos. 17245 and 26390. [Class 34 (ii)] Grass or a similar crop is dried in two stages, an initial stage in which a batch of the material is partially dried, and a final stage in which the batch is completely dried in a rotary drum by the passage therethrough of hot gases while the material is rotated in the drum, drying in the initial stage being effected by the passage through the material-of hot gases leaving the final stage. In the construction shown in Fig. 1, a rotary drum 3 of gas-pervious material is mounted within a stationary drum 1 provided with an inlet 6 and an outlet 7 for the supply and discharge of heated gases. The outlet leads to a hopper 16 which is divided into two parts by a partition 17 and two hinged perforated sheets 19, 20. Heated air from a furnace is adapted to be supplied to the drum 3 or to be diverted to the hopper by way of a trunk 26. Three flap valves 27, 28, 29 are provided for controlling the flow of the heated gases. With the flaps in the position shown, heated air flows through the drum, and passes through sheet 20, pre-heating the grass in the right-hand side of the hopper. When the grass in the drum is sufficiently dried the valve 27 is operated to close the supply of gas to the drum and divert it through the trunk 26 and perforated sheet 18 to grass in the left-hand side of the hopper. The drum is then emptied, and refilled with pre-heated grass by swinging inwardly the sheet 20. The valve 29 is then moved to cover the sheet 20, the valve 27 is restored to the position shown, and the valve 28 is moved to place trunk 26 in communication with conduit 25 leading to the right-hand portion of the hopper. The gas then flows through the grass in the drum and escapes through the grass in the left-hand portion of the hopper. In a modification an undivided hopper with a base consisting of a pair of co-operating counterweighted hinged flaps of perforated material is provided, the flap valves 27, 28, 29 and associated conduits being dispensed with. In the construction shown in Figs. 3 and 6, two dampers 27a, 27b are connected so that when one is closed the other is open whereby heated air is supplied either through pipe 8 for passage through the rotary drum 3 or through pipe 26 leading to chamber 34. In the latter case the air passes through the perforated base of one or other of two hopper sections 17a, 17b according to the position of a valve 28a operated by a handle 36. The perforated bases are hinged at 37 and are adapted to be raised or lowered by manuallyoperated ropes 38. A perforated cover 41 with rollers 42 may be placed over either of the hopper sections.

Title: Signal-seeking tuner devices
IPC: H03J3/14
Filed: 1950-07-11
Abstract: 682,888. Automatic tuning control of receivers; limiters. GENERAL MOTORS CORPORATION. July 11, 1950 [July 22, 1949], No. 17284/50. Classes 40 (v) and 40 (vi). In a tuner of the type in which the tuning movement is automatically arrested when a signal is tuned in the D.C. voltage which causes the tuning to be arrested is derived from two rectifiers to which the signal voltage is applied and having their outputs connected in series opposition, one rectifier being biased and the relative magnitudes of the rectifier outputs being such that when the signal is greater than a predetermined level and it is desired to arrest tuning movement the D.C. output is of constant level. In Fig. 3 the two diode rectifiers are connected to the input tuned circuit through capacitors 145 and 146 respectively and the second rectifier is biased by a battery 162. The voltages E 1 , E 2  produced across the respective load resistors 140, 158 are connected together by resistor 157 in series opposition so that the output is the difference voltage. If the input voltage amplitude is increased from zero the output voltage rises due to the unbiased rectifier but when the second rectifier becomes conductive the further increase is opposed and the output voltage remains constant. In Fig. 4 the two diodes are fed respectively from the primary 166 and secondary 182 of a critically coupled I.F. transformer. The effective frequency response of the primary winding as modified by the delay bias on the rectifier is indicated at K (Fig. 4b) and that of the secondary at L. The resulting response is indicated at M for one value of input signal amplitude and at O for a larger value, the effect of increasing the input amplitude being to sharpen response without changing the peak negative output. In Fig. 2 (not shown) the A.G.C. voltage for the receiver is taken from the biased rectifier and to allow for the step down ratio of the transformer only part of the voltage developed across the load of the rectifier associated with the primary winding is used.

Title: An improved telephonic time announcer
IPC: H04M3/487
Filed: 1936-01-22
Abstract: 465,647. Optical sound-reproducing apparatus for time announcements. BRENNAN, R. June 22, 1936, No. 17298. [Class 40 (ii)] Means for effecting automatic time announcements comprises the combination with sound-reproducing apparatus embodying a light - beam projector 30 and photoelectric cell 31 mounted on a base 10, of a cylindrical frame 13 which rotates at constant speed upon a vertical shaft 14 and a pair of approximately hemispherical shells 21, 23, mounted on a common horizontal axis at the top of the frame, about which axis each is capable of independent rotation, the surface of the member 21 being provided with sixty equally spaced reflecting film strips 25 which reproduce the words, respectively, from " one " to " fifty-nine " and " o'clock," and the member 23 with twelve strips which reproduce the words respectively from " one " to " twelve." The hemisphere 21 is rotated through one sixtieth of a revolution at one-minute intervals by the energizing of a solenoid 36 actuated from a master clock, by which a rod 40 rotates a ratchet wheel 41 secured to a shaft 18 rotatable in a bearing 16<1> through one-sixth of a revolution, which motion is reduced by a train of wheels 43, 44, 45, 46, in the ratio 10 : 1. The rotation of the shaft 18 is transmitted through a shaft 20 and pinion 47 to a wheel 48 loosely mounted on a fixed shaft 17, a cam wheel 49 being secured to the wheel 48, which rotates once per hour. A pivoted lever 51 has a projection 52 which bears upon the edge of the cam-wheel and the inward motion of the lever when the projection reaches the radial face 50 of the cam causes a pawl 55 to rotate a ratchet wheel 54 secured to the hemisphere 23 through one-twelfth of a revolution. A finger-piece 58, pawl 57, and ratchet wheel 56 are provided to prevent overrunning of the hemisphere. The axis of the shafts 17, 18 upon which the hemispheres are mounted is displaced to one side of the vertical axis of the frame 13 in order that the film strips on one side only of the hemispheres may be in the focal plane of the light beam as the apparatus rotates, and a film strip 29 is mounted on the semi-circumference of the frame 13 on the side of which the strips 25, 26, are out of focus, in order that the words " the correct time is " or other phrase or slogan may be reproduced before the actual time announcement. In the event of the frame 13 ceasing to rotate, a pivoted finger 33 actuated by the governor of the means rotating the frame, which normally contacts once per revolution with a projection on an insulated metal ring 34 at the bottom of the frame, contacts with the ring, and the hemispheres continue to rotate about their horizontal axis. The hemisphere 23 may be adapted for time announcements in the twentyfour hour system.

Abstract: 1,201,311. Separating liquids; analysing beryllium for copper traces; contacting liquids. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 8 April, 1968 ,[14 April, 1967], No. 17329/67. Headings BID, B1F and B1X. An aqueous liquid and an organic solvent, of different densities and electrical conductivities, are mixed together in glass container 1 and allowed to separate by settling, after which the heavier liquid is drained off through rubber tube 14 until the interface passes probes 12, whereupon the change in resistance between the probes causes a solenoid-operated pinch valve to close the tube. The control circuit (Fig. 2, not shown) can be set so that the valve closes in response to an increase or decrease in resistance. The valve is spring-loaded towards the closed position and the current through probes 2 is automatically cut off when the valve closes. The lighter liquid is drawn off through adjustable tube 6. In liquid contacting, an aqueous solution of Cu, Ni or Cr is admitted through tube 3 and an ion-extracting solution of chloroform containing sodium diethyldithiocarbamate is added through tube 4, and the liquids are mixed by stirrer 18 and allowed to settle out. In analysing beryllium for traces (5 p.p.m.) of copper, the metal is dissolved in HC1 to form a solution to which buffer solution is added to bring the pH to 4.5. The mixture is contacted with chloroform containing sodium diethyldithiocarbamate as described above, further volumes of the organic phase being added and the mixing and settling repeated after draining off the first quantity. The various volumes of organic phase are mixed together and their copper content is measured by spectrophotometry.
