IPC: C10L5/40
Filed: 1998-05-12
Abstract: The object of this invention is a method for recovering the energy from biowaste by the biowaste 1 being transported to the peat production area, where it is crushed and spread out along the surface of the peat strip 2 and mixed with the surface mass of the peat or covered in a cavity 4 in the peat strip 2 using the orifice material 5. The prevailing conditions in the peat keep the biomass in a state which is such that no energy- wasting fermentation (rotting) takes place. The mixture of peat and biomass is recovered for burning cut peat or sod peat using the same equipment as is used for the normal recovery of peat. <IMAGE>

Title: Improvements in Bombs.
Inventor: HALE FREDERICK MARTEN
IPC: F42C15/295
Filed: 1917-01-22
Abstract: 110,849. Hale, F. M., and Herbert, W. Jan. 22, 1917. Projectiles; projectile fuses.-Relates to bombs to be dropped from aircraft, of the type in which the detonator is released by means of a wind-vane device so as to arm the fuse as the bomb drops. According to the invention, the part 1 of the bomb which carries the detonator-releasing mechanism is formed at one side with a receptacle 13 arranged at an acute angle to or parallel to the axis of the bomb, the receptacle being adapted to allow of the insertion of a detonatorholder 21 from outside. In the construction shown, a transverse bolt 15 is normally held in locking engagement with the detonatorholder 21 by means of a fork 16 in which the lower end of the windvane spindle 10 rotatably engages. The fork fits against flattened sides of the bolt until withdrawn by the spindle 10 Instead of a fork, a pin passing through a hole in the bolt may be connected to the spindle 10; nr a lever engaging under a shoulder on the detonator-holder and normally acted upon by the end of the spindle may be used instead of a bolt. A modification in which the receptacle 13 is parallel to the axis of the bomb is illustrated in the Specification. In this construction, the primer-holder 5, instead of being arranged as shown in Fig. 1, is screw-threaded internally and is screwed upon a part projecting downwardly from the base 1. The Provisional Specification describes also a method of securing the rotary vanes 11 and the fixed vanes 8 to the spindle 10 and sleeve 7 respectively. Specifications 11394/13, 2057/14, and 22602/14 are referred to.

Title: Improvements in and relating to electric discharge lamp circuits
IPC: H05B41/06
Filed: 1942-01-26
Abstract: 550,309. Electricity supply to discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 26, 1942, No. 1072. Convention date, Jan. 27, 1941. [Class 38 (iv)] In order to improve the starting and re-starting of discharge lamps 1<SP>1</SP> with pre-heated electrodes, the ballast consists of an inductive portion 71 and a capacitative portion 15 in series to give a net capacitative effect and a leading current when the lamp is running, the capacity being shortcircuited at starting by the thermal switch 18 with a heater 23, so that the lamp is started on a circuit having a lagging current. The preheating current for the electrodes passes through a glow discharge thermal switch 81 described in Specification 533,249 and through the heating element 23 of the switch 18. The switch 81 is so timed that when it breaks circuit to start the discharge the electrodes are sufficiently heated to maintain it but the thermal switch 18 still requires further heating by the running current before it opens and remains open to introduce the condenser 15 and ensure a leading current for running. An arrangement of two lamps is shown in which the upper lamp is provided with inductive ballast only and, owing to the phase angle between the two supplies, stroboscopic effects are reduced.

Patent GB-764430-A (GB)
Title: Improvements in or relating to treatment of glutamic acid
IPC: C07F3/00
Filed: 1955-01-20
Abstract: Zinc glutamate salts are obtained by (1) mixing an aqueous solution containing glutamic acid with zinc hydroxide at pH 5.5-11.0, or (2) mixing an aqueous solution containing glutamic acid and a zinc salt with sufficient alkali or alkaline earth metal hydroxide to bring the pH to 5.5-11.0; zinc-magnesium glutamate is obtained by mixing an aqueous solution containing magnesium glutamate with zinc hydroxide at pH 5.5-11.0.  The above salts are all insoluble in water and can be separated from the solution.  They are probably basic salts containing three metal ions, two glutamate ions and two hydroxyl ions per molecule. The zinc salt used in method (2) may be the chloride, phosphate, sulphate or acetate.  When using crude solutions such as protein hydrolysates containing 0.1-10 per cent of glutamic acid, there are preferably used 8-10 mols. of zinc compound per mol. of glutamic acid.  The precipitation of the zinc salt then forms a convenient way of isolating glutamic acid from the solution. Alternatively the salts may be made from refined glutamic acid when 1-2 mols. of zinc compound are sufficient.  The preferred pH range for formation of the salt is 6.3-10.5, especially 8.5-9.5. Free glutamic acid may be obtained from the zinc salt by suspending it in water, adding an inorganic reagent which forms an insoluble zinc salt (e.g. sulphide or carbonate), filtering and crystallizing glutamic acid from the solution.  Examples are given of the process.

Abstract: 999, 661. Measuring noise power. GENERAL ELECTRIC CO. Ltd. Jan. 15, 1964, [Jan. 15, 1963], No. 1786/63. Heading G1U. [Also in Division G4] An arrangement for measuring noise power comprises two junction transistors 14, 15 connected to a D. C. source 9 with a common emitter load whose impedance varies with the emitter potential (rectifiers 19 to 22 and resistors 23 to 27, a means 17 indicating the sum of the collector currents and means such as a transformer 4 with a tapped secondary winding supplying the voltage to be measured to the bases in antiphase, the arrangement being such that the sum of the collector currents is substantially proportional to the square of the instantaneous amplitude of the input signal. The tapping is connected to a potential divider across the D. C. source including a voltage stabilizer (resistor 8 and zener diode 10), a variable resistance 7, for adjusting the point of their characteristic at whichthe transistors work, and a thermistor 11 for temperature compensation. The resistors shunting the rectifiers in the emitter load are so graded that as the emitter electrode potential increases the number of conducting rectifiers also increases. The transistors are silicon transistors and their working point is adjusted by the variable resistor 7 so that for very low signals when none of the rectifiers 19 to 22 conduct the non-linear part of the transistor characteristic is used. In operation each base-emitter path acts as a rectifier so that each transistor responds to alternate half cycles of the input. The current indicator 17 may be an ammeter which, because of its slow response, may indicate average noise power. The resistor 16 and rectifier 18 provide overload protection for the meter.
