Filed: 1917-03-01
Abstract: 163,725. Skipwith, H. L. d'E., and Fortescue, C. L. March 1, 1917. Thermionic oscillation generators.-The anode circuits of thermionic valves for generating oscillations for wireless signalling are energized by alternating current of three or more phases. As shown in Fig. 1, a three-phase supply P is connected through choke coils l to the anodes of three valves. The neutral point is connected through a choke coil to a point on the aerial inductance L, another point being earthed. The grids G of the valves are connected to the lower end of the aerial inductance. The normal voltage of the grids relatively to the filaments is determined by potentiometers R connected to one end of the heating batteries B, the adjustable members of the potentiometers being earthed. The oscillatory anode current passes through condensers S4. In a modification, the grid circuit is inductively coupled to the aerial inductance L in the anode circuits, and the filaments F and the neutral point of the three-phase supply are earthed. Reference has been directed by the Comptroller to Specifications 127,008 and 169,442.

In a haymaking machine comprising at least one tine carrying rake-wheel rotatable about a substantially vertical axis, the distance between the tines 19 and the axis of rotation of the rake-wheel can be adjusted. To facilitate the periodic release of hay at the delivery places on the path of rotation of the tines the tine carriers 18 are rotatably mounted for controlled pivoting movement in bearing bores 10 in the rotary member 9 attached to gear casing 5. The adjustment between tines 19 and the axis of rotation is achieved by telescoping tube 21 into tube 20 and fixing it in one of the three fixed positions by inserting pin 24 in one of the holes 23. In an embodiment the tines 19 are mounted on bush 26 which can be displaced along the rod 25. The rake wheel bears against the ground by means of supporting roller 14 which can be adjusted according to the position of the tines 19. In Fig. 2 (not shown) two rake wheels are mounted on a transverse carrier (27) and these rotate either in the same or opposite direction. In a further embodiment the transverse carrier is mounted on the gear casing 5 but there is provision for pivoting the carrier about a vertical axis and for locking it in different angular positions. The distance between the tines and their respective axes of rotation can be altered so that the tines take up different paths of rotation. The machine is attached to the three point linkage of a tractor and the rake wheels driven from the power take off of the tractor.

Title: Weighing machine
IPC: B07C5/28
Filed: 1965-01-26
Abstract: 1,066,511. Sorting articles by weight, electrically. BARKER POULTRY EQUIPMENT CO. Jan.26, 1965 [Jan.27, 1964], No.3390/65. Headings G1N and G1W. An egg grading machine has a number of weighing stations each of which is responsive to an egg weight exceeding a certain value, and means are provided to avoid incorrect selection due to impact loading by an egg on a weigh platform section of a track along which eggs are pushed Fig. 1 (not shown). WEIGHING APPARATUS. Fig. 3, also Fig. 4 (not shown). Each weigh platform section is supported from underneath by two parallel vertically spaced cantilever spring plates, which are at one end fixed to a rigid stationary frame. Deflection of the weigh platform is sensed by a differential transformer the windings 120, 122, 124 (Fig. 5) of which are fixed to the frame and the core of which is rigidly attached to the weigh platform. An electrical output signal is used to operate a solenoid which actuates a deflector arm Fig. 1 (not shown) to divert a selected egg transversely off the track to another conveyer. ELECTRICAL CONTROL CIRCUIT (Fig. 5) The differential transformer primary 120 is fed from a 400 cps source 126 and its secondary output is amplified by a pentode 148 and a triode stage 166, which is transformer coupled to a discriminator circuit, comprising resistors 182, 184, 186, 188, capacitors 190, 192 and diodes 178, 180, which is connected to a reference signal provided by the 400 cps source 126. An output signal is thereby produced at the junction of resistors 186, 188, having a D. C. level which varies with the phase sense and amplitude of  the triode stage 166 output, and is fed to an integrating and filtering circuit including L194, 196, 198, 200, C202, 204, 206, 208 whereby capacitor C208 is charged up to a D. C. voltage level which accurately reflects the weight of an egg without incurring any instantaneous voltage greater than this D. C. level due to impact of an egg on the platform. The stiffness of the springs, and the filtering and integrating circuit provide damping to accommodate impact loading. The integrating circuit is connected to the grid of a triode stage 210, and when no signal is present at the grid, the junction point 218, of a voltage divider connected to the anode of 210, is at a negative potential, which is insufficient to ignite a thyratron 220. This thyratron however will fire, only when the grid is at a potential indicative of an egg on the platform having a weight exceeding the threshold weight of a given grade, during a brief period when a switch 228 is closed by a cam 230 controlled in timed relation to the egg feeder. The output of the thyratron energizes a solenoid 232 to move a selected egg off the tracks to another conveyer. The position of the stationary winding of the differential transformer is adjustable to set the threshold value of the given grade which corresponds to zero output therefrom.

Title: Improvements in and relating to the manufacture of oxidation products of aromatic hydrocarbons by air oxidation
IPC: C07D307/89
Filed: 1925-02-06
Abstract: 249,973. Green, A. G. Feb. 6, 1925. Anthraquinone; phthalic acid and anhydride.- In the catalytic oxidation of aromatic hydrocarbons in the vapour phase by means of an oxygencontaining gas, the surplus reaction heat is absorbed by the injection of water spray or mist into the spaces between successive catalyst zones ; the water becomes vapourized by the hot gases, thereby reducing their temperature, and by adjustment of the amount of water introduced, the temperature conditions of the process can be controlled. The process is particularly applicable to the production of phthalic acid and anhydride from naphthalene and of anthraquinone from anthracene. The reaction chamber of metal such as iron or refractory material such as brick contains a number of superimposed perforated plates upon which is placed the catalytic material, which may be lumps of pumice coated with vanadium pentoxide. All metallic surfaces which come into contact with hot reaction gases are preferably coated with sodium silicate and asbestos powder. Spray producers or atomizers project into the spaces between the plates for the injection of water mist; the amount of water introduced is determined by the reading of the pyrometer projecting into the same space. A mixture of say naphthalene vapour and air, obtained by passing warm air through an insulated wooden chamber containing a number of perforated trays carrying naphthalene, is either passed directly through a heated pipe into the reaction chamber or is first preheated by means of the hot gases issuing from the chamber. The direction of the gases through the reaction chamber may be changed at intervals. The issuing gases are led into a series of empty vessels for condensation of the product, after first passing, if desired, through the preheater for the ingoing gases. Specifications 15949/98, [Class 1, Acids, alkalies, &c.], 119,517. 119.518, 145,071, 156,244 and 170,022 are referred to.
