Patent GB-344835-A (GB)
Abstract: 344,835. Recording-apparatus. KERSTING,J., 9, Brugherrenstrasse, Tempelhof, Berlin. Sept. 4, 1929, No. 26918. Convention date, Nov. 2, 1928. Void [Published under Sect. 91 of the Acts]. [Class 106 (iv).] The Specification as open to inspection under Sect. 91 (3) (a) describes a mechanical substitute for a stop-watch which obtains a record on a timesheet 87 which is wound between two drums 86, 88. The time-sheet is advanced a step when a lever 84 is depressed and released, so raising a pawl 89 to the next ratchet notch and then pulling it down again with its load. There is a seconds wheel 56 and a minute wheel 57, the latter being turned through gearing 72 one step for each revolution of the former. These wheels carry type and an impression is made when a die 103 is raised through a lever 98 and pawl 97 when lever 84 is depressed. The wheels 56, 57 are driven from a clockwork driven minute wheel 67, and a crank-handle 49 provides means for setting the device to zero. A modified arrangement is described in which a trip pawl released by clockwork closes a switch which starts an electric motor. The motor drives a wheel which turns a type-wheel one step, and after one turn reopens the switch. The type-wheel is driven by a pawl which is operative only so long as a removable hand-plug is in place.

Title: Improvements in and relating to the controlling systems for nuclear reactors
IPC: G21C7/16
Filed: 1965-08-12
Abstract: 1,073,557. Controlling reactwrs. SOC. ANGLO-BELGE VULCAIN, SOC. ANON. Aug. 12, 1965 [Aug. 19, 1964], No. 34515/65. Heading G6C. [Also in Division F2] A neutron-absorbing rod 1 is hydraulically actuated in a nuclear reactor by a system in which differential pressures in the primary fluid circuit of the reactor displace the rod in a guide tube 2 through which the primary fluid flows, this flow being controlled by a master valve 3 connecting one end of the guide tube 2 by means of tubes 4, 5 to one of two regions of the primary circuits in which prevail respectively a pressure lower than and a pressure higher than that prevailing at the other end of the tube. The primary fluid is a fluid effecting removal of heat from the core and/or its moderation and/or its temperature regulation. The master valve 3 is connected with a pilot valve 9 which controls the position of the slide of the master valve 3 in such a manner as to establish a variable orifice between the top of the tube 2 and either the tubing 4 or the tubing 5. The pilot valve 9 is itself connected with the primary circuit respectively upstream and downstream of the primary fluid circulating pump 12. The feeding of the pilot valve 9 is effected automatically or by hand by means of valves 13, 14. When it is desired to raise the rod 1 or to maintain it in a predetermined position in the tube 2, the pilot valve 9 is operated such that the slide of the master valve 3 is placed in a position for which an opening of predetermined size established communication between the top of the tube 2 and the tubing 4 connected to the lowpressure region of the primary circuit. When it is desired to introduce the rod into the core, the pilot valve 9 is operated such that the slide of the master valve 3 is placed in a position for which communication is established between the top of the tube 2 and the tubing 5 connected to the high pressure region of the primary circuit. The system is fail-safe because any absence of pressure for actuating the slide of the master valve (e.g. rupture of a conduit) involves its displacement to a position connecting the top of the tube 2 with the tubing 5 resulting in the rod being inserted into the core, and any absence of pressure of the primary fluid results in automatic introduction of the rod into the core under the action of gravity.

Title: Process for the production of motor fuel
IPC: C10G45/02
Filed: 1933-12-11
Abstract: A non-knocking motor fuel boiling between 130 and 240 DEG  C., is produced by first dividing a hydrocarbon mixture, consisting largely of aromatic hydrocarbons, into a lower fraction and a fraction at least 80 per cent of which boils between 150 and 240 DEG  C., and then subjecting the higher fraction to a refining, catalytic hydrogenation under pressure, in the presence of a catalyst comprising a metal compound and at a temperature below 390 DEG  C. As initial materials, benzols or benzines obtained from coal tars may be employed.  As catalysts, there may be used compounds, e.g. oxides, hydroxides, sulphides, halides and carbonates, of the metals of the sixth group, especially molybdenum, tungsten, chromium and uranium, and of strontium, vanadium manganese, rhenium, titanium, zirconium, zinc, cadmium, aluminium and cobalt.  The catalyst may be deposited on carriers, preferably in the colloidal condition.  The pressures employed may vary between 20 and 1000 atmospheres and the temperatures may lie between 200 and 390 DEG  C, preferably 300 or 340--390 DEG  C. Hydrogen alone or mixed with other gases e.g. nitrogen, carbon monoxide or dioxide, hydrogen sulphide, water vapour or methane, and the quantity may vary from 300 to 2000 cubic metres per ton of hydrocarbon treated which may be in the vapour phase.  In a preferred method, a hydrocarbon mixture consisting mainly of aromatic hydrocarbons, e.g. crude or heavy benzol, is divided into two fractions, one boiling below 130 DEG  C. and the other above, the second fraction being subjected to a refining hydrogenation and the first fraction to a chemical refining, e.g. with sulphuric acid.  The products may be blended with other motor fuels, e.g. benzine.  In an example, crude benzol is divided by distillation into a lower fraction boiling up to 160 DEG  C., and a higher fraction boiling between 160--220 DEG  C.  The higher fraction is passed with hydrogen under a pressure of 200 atmospheres and at a temperature of 370 DEG C., over a catalyst comprising molybdic acid, zinc oxide and magnesia the conditions being such that no substantial splitting or hydrogenation of the aromatic nuclei takes place.  A purified heavy benzol of boiling range 150--225 DEG  C., is obtained. Specifications 349,655 and 372,783 are referred to.

Abstract: 1,014,164. Thermal regenerators. PHILIPS GLOEILAMPENFABRIEKEN N. V. Sept. 14, 1962 [Sept. 19, 1961], No. 35168/62. Heading F4K. A heat exchanger comprises, a first housing 2 provided with external heat transfer surfaces 5 and containing a heat-storing mass 1 which is traversed alternately in one direction by a first heating medium and in the opposite direction by a second medium to be heated; a second housing 6 surrounds housing 2 and is spaced from it to form an annular reflux channel 16 through which some of the medium having the higher thermal-capacity flow intensity is caused to flow in order to obtain thermal balance within the heat exchanger. Assuming that the thermal-capacity flow intensity of the hot medium flowing in at A is greater than that of the medium flowing in at B, then medium A gives up heat to the heat storing mass I during its passage. After passing through the mass, some of the medium A as it flows out through the duct 11 passes via valve 13 and duct 12, through the annular reflux channel 16 which it leaves by way of ducts 9. During this reflux the medium absorbs, through the helical wound copper wire 5 and the housing 2, part of the heat given up to the mass 1. When the colder medium passes through the heat exchanger, the valve 13 is closed, hence preventing flow through the reflux channel 16. The medium is heated by contact with the hot mass 1. The mass 1 consists of layers of metal gauze soldered to the inner side of housing 2. A modification employing valves operated by differential fluid pressure is described (Fig. 2, not shown).

Title: Improvements relating to the recovery of ammonia from coal-gas and like gases
IPC: C01C1/12
Filed: 1931-12-24
Abstract: In the recovery of ammonia from coal gas, the amount of ammonia in the gaseous products is distributed so that its concentration in one portion of the gas is increased, and this enriched portion is passed into a solution of ammonium bicarbonate in a washer from which the solid salt is recovered.  By this process the carbon dioxide in the crude gas is utilized for the purpose of separating the ammonia as bicarbonate.  One portion of the gas is passed through the usual condensers and scrubbers, from which the ammonia is recovered, and added to the other portion, which enters the ammonium bicarbonate washer.  Sodium chloride may be used instead of or as well as ammonium bicarbonate, in which case sodium bicarbonate will separate, and ammonium chloride will accumulate. The contents of the absorber may then be filtered and sodium bicarbonate obtained; the filtrate is boiled to expel ammonia and carbon dioxide to be returned to the crude gas, and to leave a solution of ammonium and sodium chloride which may be worked up to yield ammonium chloride.  To redistribute the ammonia, the gas made during one period of carbonization may be deprived of its ammonia, which is then added to the gas made during the next period, or two installations may be operated side by side, the ammonia from one being passed into the crude gas in the other which alone is provided with an ammonium bicarbonate washer.
