Abstract: 129,013. Lea, E. C., and Orlebar, B. O. C. Sept. 20, 1917. Tunnelling by boring. -An earth - boring machine, more particularly for forming military tunnels or passages, comprises a cylindrical casing 1, a cutting-head 2 driven by a motor 3, a central nut 5 for feeding the casing and head forward, and anchoring-. struts 4 extending radiallv from the nut and adapted to be projected through longitudinal slots 6 in the casing and into the surrounding earth to prevent longitudinal movement of the nut and rotation of the casing. The struts comprise telescoping parts 4<a>, 4<b>, the parts 4b being connected by links 7 to a toothed disk 8 which is rotated by a pinion 10 to project or withdraw the struts. The links 7 may be adjustable, or the parts 4<b> may carry a relatively adjustable outer part. Two sets of slots 6 are provided, the struts being angularly adjusted after each advance of the machine so as to obtain a better purchase on the earth. The cutter head 2 is slightly conical and comprises arms 13 and a rim carrying reversible double-edged cutters 14; the head is connected to the casing by angle rings 15, 16 enclosing two sets of bearing-rollers 17, 17a, Fig. 5, on axes at right-angles to each other, the rollers being supported by a cage formed of two angle rings 18. The axle 19 of the cutting-head is threaded to engage the nut 5, and its rear end is supported in a spider 21. The motor 3 is suspended from the axle 19 and is prevented from rotating by means of a hooked bracket 23 on the casing 1. To permit a slow feed to be obtained while using a coarse thread on the axle 19, the nut 5 is rotated from the axle through gear-wheels 29, 28 which are normally held in mesh with wheels 26, 27 by a spring catch 31, but may be moved on the spindle 30 to enable the nut to be advanced by hand. The cutter head and casing may each be in three or more sections, and the cutter head may have a central conical portion projecting forwardly. To relieve the floor below the casing and so facilitate horizontal boring, the machine may be connected to a lever 32, Fig. 8, carrying a balance-weight 34 and provided with a fulcrum in the form of a roller 33 which runs on a track 37 yieldingly carried in a frame 35 by a spring 38, Fig. 9; the spring is supported by a carriage 39 which may be adjusted by screws 41 resting in bearings 43, which are themselves adjustable. Ball bearings 49 and load-indicating means 46 also are provided. The spoil may be removed by a screw conveyer 101, Fig. 11, driven from the motor 3 and supported in a casing 102 connected to the spider 21. A mouthpiece 105 collects the spoil. A bucket or chain conveyer may replace the screw. The ca.sing 102 of the conveyer may replace the lever 32, Fig. 8.

Patent GB-764603-A (GB)
Title: An improved process for the granulation of superphosphate
IPC: C05B19/02
Filed: 1954-05-10
Abstract: In the granulation of den superphosphate in a single operation in the absence of added water and without the supply of heat the superphosphate used is in a state such that its water content is between 8 and 13 per cent. and the numerical value of the sum A + 4L, defined below, is between 108 and 116 and preferably between 111 and 112.5.  A, which is always less than 100, is the percentage of assimilable P2O5 calculated on the total P2O5 of the superphosphate, i.e. that soluble in water and citrate, and L is the percentage of uncombined phosphoric acid, calculated as P2O5 based on the weight of superphosphate.  If the superphosphate has an A + 4L value outside the above limits, the value may be brought within the limits by the addition of either a material diminishing the acidity, such as crude phosphate or ammonia, or an acid such as sulphuric or phosphoric acid, or of a chemically inert material which lowers the value of the factor L and which itself may be a fertilizer.  According to examples (1) Moroccan phosphate (72 per cent. P2O5) was treated with sulphuric acid and the granulation effected 15 minutes after the superphosphate left the reaction chamber at a temperature of 35 DEG C.  The water content was 12.6 per cent. and the values A, L and A + 4L were respectively 78.8, 12.23 and 128, the latter value being outside the characteristic limits.  Granulation was inadequate.  A further example (2) shows that superphosphate allowed to mature for 2 hours whereby its A + 4L value was reduced to 118 is still not capable of satisfactory granulation.  (3) The superphosphate resulting from the acid attack described in (1) above was matured for 24 hours by which time the A + 4L value was 114, and the superphosphate could be satisfactorily granulated, to yield a product where 80 per cent of the grannules are between 1 and 5 mm.  Another example (7) describes the production of a superphosphate which six hours after production had an L value of 7 and an A + 4L value of 123, and which could not be satisfactorily granulated.  On the addition of crude phosphate or anhydrous ammonia to reduce the acidity and bring the L value to 6, and the A + 4L value to 111, granulation was effected and hard granules which required no further drying, resulted.

Title: Method and apparatus for the production of gaseous mixtures containing acetylene and ethylene
IPC: C07C4/02
Filed: 1962-04-10
Abstract: <PICT:0965719/C4-C5/1> Acetylene and ethylene are formed by the action on a liquid hydrocarbon of an electric arc produced intermittently between two electrodes one of which is stationary and the other of which is moved in continuous longitudinal reciprocating movement into contact with and then away from the stationary electrode at a predetermined frequency having a cycle of not more than one second.  The impact of the meeting electrodes keeps them clean and strikes the arc which is interrupted as they move apart. When alternating current is used the frequency of the moving electrode may be the same as the supply and synchronized so that contact of the electrodes occurs when the voltage is near zero.  The electrodes may be a simple pair or as shown in Fig. 2 may comprise two fixed electrodes 11 and 12 connected to the electricity supply and a pair of connected moving electrodes 13 and 14 or (Fig. 3, not shown) may comprise six such sets of electrodes for use with a three-phase supply.

Title: Receiver channel selecting apparatus and a driving circuit therefor
IPC: H04N5/44
Filed: 1974-03-28
Abstract: 1464958 Ultrasonic remote control SONY CORP 28 March 1974 [29 March 1973] 13875/74 Heading G4F [Also in Division H3] In a channel selecting arrangement including a pulse generator 8 which is responsive to a continuous control signal (S1, Fig. 4, not shown), having a duration longer than a predetermined time for generating repetitive output pulses (TP) having a period (T) equal to the predetermined time duration, the pulses are applied to a receiver channel selecting apparatus 18 for changing the channel selected thereby, and the pulse generator is also responsive to intermittent control signals each having a duration shorter than the predetermined time for varying a time constant of a time constant circuit 8 of the pulse generator so as to generate an output pulse in response to each intermittent control signal. As shown an ultrasonic remote control signal transmitted from a remote control transmitter 1 to a remote control receiver 2 closes a channel selecting switch 3 of a T.V. receiver. This causes a transistor 4 to turn off so as to allow an astable pulse generator 5 to generate short pulses (TP) such as 50 milliseconds duration at output S4 at longer intervals (TM) such as 0À5-1 second as determined by short and long RC time constant circuits 12, 13 and 10, 11. As long as the control signal S1 is applied, the pulse generator 5 operates to generate pulses (TP) at S4 which make a transistor 15 intermittently conduct to operate a stepping motor 16 so as to step the channel selector shaft 17 of a tuner 18 which has a manual control knob 19. Short intermittent control signals of duration less than the period (T) of the astable pulse generator 5 each cause a corresponding output pulse S10 at the output of pulse generator for more rapid channel stepping by the stepping motor 16. When such a short control signal ends channel selecting switch 3 opens and transistor 4 turns on to make a transistor 21 conduct. This connects a resistor 22 in parallel with the resistor 21 so as to reduce the RC time constant of 11, 21 which enables the pulse generator to be rapidly reset to its initial state of transistor 6 on and transistor 7 off before the next intermittent control signal is applied. In a modification (Fig. 5, not shown), a differentiating circuit (25, 26) responds to the trailing edge of the short intermittent control signal to operate the time constant varying transistor 21 to rapidly reset the pulse generator. The output from the pulse generator may drive a ring counter 28 to select a preset tuning voltage for application via a corresponding diode (30A-30E) to an electronic tuner 31 such as a variable capacitance diode.
