Title: Cleaning Shop for Cleansing Work by Means of a Sand Jet.
Inventor: ALEXANDER ALBERT EDGAR
IPC: B24C9/00
Filed: 1917-12-31
Abstract: 117,032. Alexander, A. E., (Weller & Co., C.). Dec. 31, 1917. Sand-blast. - In a shop in which work is cleansed by a sand jet and the resultant dust is removed by an artificially-produced current of air, adjustable air-admission channels leading from the atmosphere to the cleaning-room are so disposed that air currents in the form of a wedge are always directed on to the spot where most dust is forming and the workman is not inconvenienced thereby. The shop has a ceiling and walls of sheet iron and comprises a cleaning-room 1, Fig. 3, and a small room 2, in which is placed the sandbox 3 and the workman usually stands. The work is moved into and out of the room 1 through a double door 4 and on a track 6 and the room 2 has a door 5. Air is drawn from the room 1 through an outlet 15 in the ceiling by an exhauster, and air enters through top and bottom casings 17 mounted in openings in the wall parts 16 to vertical rotatable cylinders 18, whence it passes through longitudinal slots to blocks 19, which can be adjusted by rotation of the cylinders to direct the currents of air on to the work. The room 1 has a grate floor 7, through which the sand &c. falls into a collecting-pit 8 extending also below the room 2. The pit narrows at the bottom, where a screen conveyer 9 is placed below an horizontal-wire sieve 11 to transport the sand to an elevator 10 conveying it back to the box 3, an apparatus for the removal of dust being provided in the conduit leading to the box and discharging through piping into the outlet 15. A mixing-apparatus and compressed-air piping 13 are provided at the bottom of the sand-box to cause the sand to be blown on to the work under high pressure by a conduit 14. In another form, air-admission channels 22, Fig. 5, are slidably mounted in vertical slots 21 in the wall parts 20 and are suspended by guide-rails by sleeves so that they can be moved longitudinally parallel to each other, as indicated by dot-and-dash lines, the inner ends of the channels being bent towards each other so that the currents of air therefrom cross at right-angles. The cleaning-room 1 has a double door 4<1> opposite the room 2.

Title: Improvements in and relating to iron-chromium alloys
IPC: C22C35/00
Filed: 1934-07-02
Abstract: Iron-chromium alloys containing 50-72 per cent of chromium, 1-5 of carbon, 0,5-15 of nitrogen and the balance iron are prepared by reducing chrome ore with a carbonaceous reducing agent in the presence of oxygen-free nitrogen or ammonia gas.  The gas may be under pressure and may be passed into the ore during the reduction. When the chrome ore and reducing agent are melted down in a suitable furnace, e.g. an electric furnace having carbon electrodes to form a molten slag containing the oxides of iron and chromium which are then reduced, the gas is bubbled through the slag during the reduction of the oxides contained therein.

Title: Improvements in or relating to cardiac pacemakers
Inventor: FYSON JOHN WILLIAM
IPC: A61N1/365
Filed: 1969-04-16
Abstract: 1300416 Heart pacemakers NATIONAL RESEARCH DEVELOPMENT CORP 15 April 1970 [16 April 1969] 19547/69 Heading A5R [Also in Division H3] An inhibited-demand pacemaker comprises means 19, 20 for generating heart-stimulating pulses, means 12, 13 for monitoring natural heartbeats by detecting electrical impulses, and means 15, 16, 17 for inhibiting the pulse generator during detection of electrical impulses which are above a first threshold frequency, preferably of 55 to 75 pulses per minute (p.p.m.) and below a second threshold frequency, preferably of 200 to 400 p.p.m. An amplifier 12, having a frequency response of -18dB/octave below 15Hz and above 150Hz, is connected between electrodes connected to the body and together with a trigger circuit 13 acts as the monitor. In the absence of natural heart-beats, or if the beats are below the first threshold frequency, an oscillator 19 is freerunning at a normal frequency of 70 p.p.m. and triggers a pulse generator 20 to stimulate the heart at this frequency. If the heart is beating normally at higher than the first threshold frequency, amplifier 12 passes the R-wave portion of the normal ECG to the trigger circuit 13 which triggers a monostable multivibrator 15 from its staible to its quasi-stable state. A change of state of multivibrator 15 triggers a resetting circuit 17, via a capacitor 16, to reset oscillator 19 back to the start of its periodic cycle and thus inhibits the generator 20. If interference pulses are detected above the second threshold frequency, the multivibrator 15 is caused to be triggered so that it is held in its quasi-stable state, no signals being passed via capacitor 16 so that stimulating pulses are produced by generator. After multi-vibrator 15 has been held in its quasistable state for a predetermined time, preferably less than the periodicity of oscillator 19, a frequency-shift signal is supplied via a resistor 46 to the oscillator 19 so that generator 20 supplies pulses to the heart at an increased frequency, preferably 95 to 110 p.p.m.

Patent GB-775404-A (GB)
Title: Improvements in bis(cyanopentenoxy) alkanes
IPC: C23F11/14
Filed: 1955-07-07
Abstract: The invention comprises bis-(cyanopentenoxy) alkanes having the formula (CNCH2CH= CHCH2CH2O)2R, in which R is an alkylene group of 2 to 8 carbon atoms.  Thus R may be ethylene, propylene, isopropylene, butylene, isobutylene, pentylene, hexylene, isohexylene, heptylene, 1,1,2-trimethylpentylene or octylene.  The novel products may be prepared by reacting compounds having the formula (XCH2CH= CHCH2CH2O)2R, in which X is chlorine or bromine, with a cyanide donor compound having an inorganic monovalent cation, e.g. sodium cyanide, potassium cyanide, lithium cyanide, cuprous cyanide or hydrogen cyanide.  The reaction may also be effected by introducing hydrogen cyanide into a reaction mixture that includes a salt, such as a chloride, of sodium, potassium, lithium or monovalent copper.  The reaction is preferably conducted in an inert solvent such as water, methanol, ethanol, isopropanol, propanol, chloroform, ethylene dichloride, acetonitrile or mixtures at 40 DEG  to 175 DEG  C., more preferably at 55 DEG  to 140 DEG  C., and at atmospheric or increased pressure.  The reaction time is usually 1 to 6 hours or more.  On completion of the reaction the product is extracted with a water-immiscible solvent, e.g. chloroform or ethylene dichloride, and the product layer is washed with acid, water, alkali and water again and then dried, filtered, stripped and if desired distilled.  The products are useful as pesticides, and may be reacted with dicyandiamide to form products useful as protective coatings, or with thioalcohols to form lubricating oil additives.  In examples, the bis-(5-cyanopent-3-en-1-oxy) derivatives of (1) ethane, (4) propane and (7) octane are obtained by reacting the corresponding chloro- or bromocompounds with cuprous cyanide in acetonitrile; bis-(cyanopentenoxy) derivatives of (2) ethane and (3) propane are obtained by treating a mixture of CuCl, Cu, HCl, KCl and CaCO3 with the corresponding bis-(halopentenoxy) alkane and hydrogen cyanide; (5) bis (5-cyanopent-3-en-1-oxy) butane and (6) the corresponding hexane are obtained by reacting the bis-(halopentenoxy) alkane with sodium or potassium cyanide in acetonitrile.  Specification 771,848 is referred to.

Title: A method of gasifying pulverised coal
Inventor: KAWAI TOSHIO
IPC: C10J3/46
Filed: 1958-06-20
Abstract: 840,700. Gasifying powdered coal. SUMITOMO CHEMICAL CO. Ltd. June 20, 1958, No. 19773/58. Class 55 (1). A method of gasifying pulverized coal wherein the coal is entrained in the gasification reactants, the gaseous stream being maintained in ascending vortex flow and a portion of the coal of larger particle size being separated from the gaseous stream by the provision of a restricted stream in the upper part of the gasification furnace, where the larger particles so separated are retained to undergo further gasification, is characterized in that pulverized coal is used in which not more than 20% by weight of the particles have a size exceeding 500Á, and not more than 30% have a size less than 100Á. As shown, pulverized coal entrained in oxygen and mixed with steam is injected into furnace 1 at a temperature of about 1500‹ C. in a downwardly oblique tangential direction through 4 and 5 at a velocity of 50-150 m./sec. so as to form an ascending vortex stream 7. The top of the furnace has an orifice BD which causes the vortex stream to converge as shown by line 8, thereby creating dead space 3. Heavier coal particles having a minimum diameter of more than 150Á entrained in the converging stream are thrown out of the vortex stream and move along paths shown by dotted lines 10 until gasification has proceeded further and virtually all the particles have been reduced to a particle size of not more than 150Á, whereupon the particles become once more entrained in the vortex stream and pass out through BD with the gas stream. Slag and molten ash is removed through the bottom 6 of the furnace, and the gas leaving the furnace is cooled by means of steam or a water spray in passageway 2 to prevent adhesion of molten dust. The theory governing the process is described. Specification 840,699 is referred to.
