Title: Improvements in the manufacture of organic mercury compounds
IPC: C07F3/10
Filed: 1933-11-03
Abstract: Alkoxyalkyl mercuric salts are prepared by reacting an alkoxyalkyl mercuric compound in which one mercury valency is attached to oxygen, hydroxyl or an acid radicle giving an easily-soluble salt, in the presence of an organic solvent, with an oxygen-containing acid which is free from mercapto groups and is capable of forming a salt less soluble in the solvent than the starting material.  The products possess preserving and disinfecting properties and are useful for destroying pests and immunizing seed grain.  The alkoxyalkyl mercuric oxides may be obtained by treating the molecular quantity of alkoxyalkyl mercuric halides with a semi-molecular quantity of silver oxide in acetone solution and removing the precipitated silver chloride. Solvents mentioned are aliphatic alcohols and ethers, liquid ketones and aromatic hydrocarbons, e.g. ethyl alcohol, acetone, benzene and diethyl ether.  Suitable acids are sulphuric, phosphoric, arsenic, oxalic, succinic and tartaric acids. Examples are given of the preparation of (1) methoxyethyl mercuric sulphate from the hydroxide (obtained by treating the chloride with caustic soda) and the formate; (2) methoxyethyl mercuric orthophosphate and oxalate from the hydroxide; also the oxalate from the acetate; (3) methoxyethyl mercuric succinate from the hydroxide; (4) o-methoxycyclohexyl mercuric phosphate from the hydroxide, which is obtained by the action of caustic soda on o-methoxycyclohexyl mercuric chloride; (5) methoxyethyl mercuric arsenate and tartrate from the hydroxide.  The sample furnished is prepared by introducing an olefine mixture consisting of amylene, ethylene and propylene into methyl alcohol, adding mercuric acetate in methyl alcohol, allowing to stand and removing methyl alcohol in vacuo, and finally treating the resulting methoxyalkyl mercuric acetates with sulphuric acid in ethyl alcohol to precipitate the sulphates.  Specification 335,527, [Class 2 (iii)], is referred to.  The Specification as open to inspection under Sect. 91 describes also the treatment of p-methoxycyclohexyl mercuric hydroxide, obtainable from the chloride by the action of caustic soda, with phosphoric acid, and contains an example corresponding with the description of the preparation of the sample.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in steam generators and furnaces
IPC: F23M5/08
Filed: 1926-12-07
Abstract: 263,778. La Mont Corporation, (Assignees of La Mont, W. D.). Dec. 26, 1925, [Convention date]. Walls. - A furnace wall is cooled by positively circulating water through tubes placed close to or embedded in the wall. The tubes are connected to drums or headers and may serve as an independent steam generator, particularly as an instantaneous or film tube generator of the kind described in Specification 171,735, [Class 123 (ii), Steam generators]. Water is circulated downwardly through vertical tubes embedded in a furnace wall by means of a pump. A wall has inner and embedded sets of cooling tubes 3, 4, Fig. 9, connected to upper and lower headers 13, 14, 23, 24. Water is supplied to the upper headers by a pump 17 connected to collecting vessels 6, 26, from which steam may be withdrawn. The two sets of tubes may have a common circulation, they may serve as independent generators operating under different pressures, or the embedded set may serve to superheat the steam generated in the inner set. In a modification, two sets of tubes embedded in a wall are connected to common upper and lower headers and steam is taken from a lower header and led into a superheater consisting of vertical tubes, connected to headers arranged above the furnace chamber. A boiler having tubes embedded in the furnace wall may be combined with an ordinary water-tube boiler arranged above and behind the furnace. A furnace wall boiler having a short back portion 3, Fig. 14, and a long front portion 57 is so combined with an ordinary water-tube boiler that the furnace wall boiler may be operated as a separate unit or it may have a circulation in common with the water-tube boiler. An auxiliary circulation pump 66 supplies water to the front header 53 of the furnace wall boiler. Cooling tubes connected to headers may be placed across the top and bottom of a furnace, and the circulation through these tubes may be in parallel or series with or separate from the circulation through the tubes of the side walls. The circulating pump 11, Fig. 28, forces water upwardly through the steam generating tubes 3 which discharge into a steam separating drum 23. The pump draws the separated water from the drum and from a further separating and steam supply vessel 6 connected to the drum. The lower ends of the generating tubes may be fitted with nozzles causing the water to take the form of a film on the insides of the tubes. Water is forced up a tube 126, Fig. 31, closed at its lower end and discharging into an upper drum 23, and steam is led from the drum through an inner tube 125 opening into a collector 127. Water is returned to the circulating pump 11 through a pipe 119. Mercury or other liquid having a high boiling point may be used as a cooling-agent in place of water.

Abstract: 468,185. Discharge apparatus; wireless signalling. TOULON, P. M. G. Nov. 13, 1936, No. 31113. Convention date, Nov. 13, 1935. [Classes 39 (i) and 40 (v)] In a known form of cathode-ray frequency multiplier shown in Fig. 1, a beam of electrons generated by the electron gun 2, 3, 4 is deflected by plates 5, 51, 6, 7 in a circular path and falls on the apertured screen 8, which divides the beam into a number of clusters of electrons ; according to the invention, the screen 8 is replaced by a number of pairs of deflecting plates 18, 18<1>, 19, 19<1>, Fig. 2, which deflect the beam periodically and alternately in different directions. The loss of electrons intercepted by the screen 8 is thus avoided. The sets of plates a, b are connected together and to sources of opposite potential by leads 20, 21, so that deflecting fields of opposite sign exist between adjacent pairs of plates. The clusters of electrons are concentrated by an electron lens, or by plates 9 ... 12 energized in opposite phase to the plates 5, 5<1>, 6, 7, onto a collecting electrode which may form a receiving or transmitting antenna. The deflected clusters of electrons are arranged to fall alternately on the ends 13, 14 of the antenna and maintain it in oscillation. The antenna is water-cooled by pipes 15, 16 one of which acts as a lead to a source of positive potential. A spherical or parabolic mirror 17 is provided behind the antenna. If the generated frequency differs only slightly from a received frequency rectification occurs at the antenna and a current varying at the intermediate frequency is produced in lead 16, the tube acting in this manner as a heterodyne receiver.

Title: Intruder alarm systems
Inventor: PEARSON HOWARD
IPC: G08B13/26
Filed: 1960-09-12
Abstract: 892,872. Intruder alarm systems. AMERICAN DISTRICT TELEGRAPH CO. Sept. 12, 1960, No. 31296/60. Class 118. A transmitting antenna array T (Fig. 1) is fed with a radio frequency signal part of which is received by a receiving antenna array R and fed to a receiver, a direct electrical coupling between the signal source and the receiver being also provided. Changes in the capacitative coupling between the arrays T and R and in the capacitance between each array and ground, which occur on the approach of an intruder, change the average value of the received signal at a rate faster than a predetermined one and result in a alarm signal being given. As described the signal source is a tuned-anode oscillator, including tube 30 (Fig. 3) provided with regenerative feed-back via coils 31, 32, which feeds the transmitting antenna array with signals at a frequency between 100 kc/s. and 200 kc/s. A coil 37, inductively coupled to the coil 32, provides a direct transfer of energy to the receiving circuit, which consists of a parallel resonant circuit coupled to the detector tube 38, which also acts as a half-wave voltage doubler. The receiving circuit is tuned to a frequency which differs from the oscillator frequency by an amount depending on the Q of the circuit so that it operates on a steep portion of the tuning curve. The composite A.C. signal delivered to the tube 38 is rectified and doubled, resulting in a D.C. voltage being developed between terminal 44 and ground, which normally is unchanging so that no signal voltage is applied via 47, 48 to the pentode amplifier tube 46. Capacitor 47 and potentiometer 48 form a differentiating circuit with a time constant of about 20 seconds, so that slow changes in the D.C. voltage caused by weather changes and the like will not affect tube 46. More rapid changes will be amplified by tube 46 and passed via a further differentiating circuit 50, 51 (having a similar time constant) to a second amplifying tube 49. The anode current of tube 49 flows in winding 52A of a differential relay and is normally balanced by flow via potentiometer 53. Changes in the anode current operate the relay which transmits an alarm signal to a remote station (not shown). The sensitivity is adjustable by means of potentiometer 48. Capacitor 55 gives negative feed-back for steep front pulses such as are produced by lightning to prevent spurious operation of the alarm.
