Patent GB-1398190-A (GB)
Title: Breath tester
IPC: G01N27/12
Filed: 1973-07-18
Abstract: 1398190 Measuring alcohol concentration in breath: monitoring battery voltage BORGWARNER CORP 18 July 1973 [15 Aug 1972 19 March 1973] 34262/73 Headings G1N and G1U The alcohol content of a breath sample is determined by feeding the sample to a heated detector unit 24 AB (Fig. 2) comprising a bead of semiconductor material with two embedded electrodes 24A, 24B, the alcohol producing a fall in electrical resistance which is measured at 16, or may be used for the selective energization of lamps, indicating whether the alcohol concentration is above or below a pre-set value. The detector is prepared for the test by causing a pump 26 to blow ambient air over it. When its resistance is sufficiently high, as shown by meter 16, a continuous breath sample from e.g. an intending car driver, is directed over the detector and a resistance reading taken after a predetermined time. In an automatic embodiment Figs.4A and 4B operation of a battery switch 19 energizes a relay K1, producing the following sequence. (a) Pump 26 and heaters 24C, 24D are energized to purge the detector element 24AB, whilst an LED 166 indicates "WAIT". The temperature of the detector is limited by thermostat switches TS1, TS2. (b) When the thermostat TS1 is operated and the detector resistance is sufficiently high to cut off transistor 185, a timing circuit comprising resistor 170 and capacitor 171 is initiated to energize relay K2 after a pre-set delay, whereby an LED 167 indicates "READY". (c) The person whose breath is to be tested now blows over the detector unit through a pressure switch 50, to light a "TEST" lamp 168 and energize relay K3. After a pre-set delay determined by resistance 207 and capacitor 205 consistent with continuous closure of switch 50 produced by an uninterrupted blow, SCR2 fires to energize relay K3 and measurement of the detector resistance is effected. If the alcohol concentration is high and the resistance is low, Zener diode 215 breaks down, SCR3 fires and LED 162 indicates "WARN". With a higher alcohol concentration Zener diode 220 also breaks down, SCR4 fires and LED 163 indicates "FAIL". If the detector resistance remains high, a timer circuit comprising resistor 231 and capacitor 233 fires SCR5 after a delay and LED 161 indicates "PASS". The battery supply unit Fig. 4B includes a  timing circuit for disconnecting the battery 32 after a time interval pre-set by resistor 130 and capacitor 131, and a voltage checking circuit for comparing the battery voltage with that across a Zener diode 116 and lighting an LED 164 when "RECHARGE" is necessary.

Title: Improvements in and relating to expanded plastic materials produced by moulding, andto the manufacture of articles from them
IPC: B29C33/12
Filed: 1957-11-04
Abstract: 859,314. Moulding expanded plastic materials. BOURGOIS, J. Nov. 4, 1957 [Nov. 9, 1956 ; Jan. 18, 1957 ; May 7, 1957], No. 34313/57. Class 87(2). [Also in Groups XIV and XXXI] Plastic material is expanded by heating it in an apertured mould whilst subjecting it to a stressing pressure controlled by means responsive to the internal pressure developed in a closed pilot mould which is subjected to the same conditions of heat as is the apertured mould, and which curtains a charge of the same composition. The plastic material, e.g. polyvinyl chloride, polystyrene, polyethylene, polyurethane, ethoxylinic resin, or silicone material, may be expanded in an autoclave 7, Fig. 3, in light-weight moulds having apertures communicating with the autoclave interior, whilst controlling the pressure by introducing air into the autoclave 7 through an electrically operated valve 34 in response to the increase in pressure in a pilot mould 30 containing a predetermined quantity of the plastic material. The expansion of the material in the pilot mould 30 causes a metal diaphragm 31 to engage an electrical contact 32 to energise a relay to open the valve 34. The resulting increase in pressure in the autoclave disengages the diaphragm 31 from the contact 32 until the pressure within the pilot mould 30 again rises above that in the autoclave. The pressure acting upon the light weight moulds is thus maintained substantially the same as that within the pilot mould. In applying the method to the manufacture of a padded arm rest comprising a perforated sheet metal plate covered with expanded plastic material the perforated plate 14, Fig. 7, is arranged as the top wall of a mould 18 having clamped thereto a peripheral inverted L-shaped member 19 forming a passage through which the charge 22 in the mould may expand. The parts 18 and 19 are coated with a plastisol before the charge 22 is introduced into the mould and expansion effected in the autoclave 7, so that the finished arm rest has an outer non-cellular skin 16, Fig. 8, covering the sponge material 15 anchored to the plate 14 at the perforations 17. The plate 14 may, alternatively, be embedded completely in the plastic material. A motor cycle saddle may be made in the same manner as the arm rest. There is also described the manufacture of a vehicle seat or back rest having springs embedded in expanded plastic material. The moulding of several other articles is referred to, including that of a toroid of resilient cellular material for replacing the inner tube of a pneumatic tyre.

Title: Process for treating fibrous materials with alkaline liquids of mercerizing strength
IPC: D06M11/38
Filed: 1953-12-14
Abstract: Fibrous textile materials, e.g. of cotton, are treated with an alkaline liquid of mercerising strength which is free from phenol or its homologues but contains a sulphonamide of the formula R-SO2-NH-X, where R is a paraffin radical having a chain of 5 to 8 carbon atoms and X is hydrogen or an alkylol group, e.g. methylol or ethylol.  The liquid may also contain glycerol diethyl ether.  The preparation of suitable sulphonamides is described (see Group IV (b)).ALSO:Aliphatic sulphonamides of 5-8 carbon atoms or N-alkylol derivatives thereof are obtained by reacting aliphatic sulphochlorides of 5-8 carbon atoms with ammonia or an alkylol amine.  The sulphochlorides may be obtained directly by sulphochlorination or by reacting the halides of the corresponding paraffins with thiourea in alkaline solution and subsequently treating the S-alkyl-isothiourea salts obtained with chlorine.  In example 1 equal parts by volume of chlorine and sulphur dioxide are introduced at 20 DEG  C. under irradiation into 400 parts of a benzine fraction boiling between 30 DEG  and 50 DEG  C. (5-7 carbon atoms) until the specific gravity of the liquid is 1.1.  The unreacted benzine is distilled off and the sulphochloride is run into a saturated ammonia solution at 5-6 DEG  C. over 7-8 hours, while ammonia gas is being passed through.  Thereafter the mixture is warmed gradually to 20 DEG  to 25 DEG  C. and sodium hydroxide is added until an alkaline reaction is obtained.  The mixture is then boiled until the ammonia disappears and cooled and neutralized, and the sulphonamide is obtained by removing the lower layer.  In example 2, a sulphochloride is reacted with a solution of monoethanolamine in chloroform at 20-25 DEG  C., and to the product is added a saturated sodium chloride solution and hydrochloric acid until a slight acid reaction is shown. Thereupon unreacted monoethanolamine is removed and chloroform is evaporated.  A sulphonamide may also be obtained from a sulphochloride derived from amyl chloride.

Title: An installation for heating powdered material containing alkalies
IPC: F27B7/20
Filed: 1960-10-12
Abstract: <PICT:0942893/C1/1> In a process for heating and burning cement raw materials containing alkalies, which comprises preheating raw materials by direct contact with the exit gases from the kiln, part or all of the gases are diverted into a cyclone containing fine granular material (limestone or cement raw materials) on which the alkalies present in the gas are precipitated and removed from the system. The exit gases from the kiln 1, Fig. 1, pass via conduit 2 into cyclone 3 where the alkalies are precipitated on fine granular material contained therein. Exit conduit 10 leads to the preheating apparatus consisting of a group of heat exchange separators, cyclones 11, 12, 13 and 14 connected in series by conduits 15, 16 and 17 so that the exit gases are sucked through the cyclones and a dust collecting system 6 (e.g. electrical precipitator) by fan 18. The material collected in the electrical precipitator may be fed back into cyclone 3 through pipe 7 and conduit 2 for precipitating alkalies or may re-enter the preheater system through pipe 43, situated above pocket wheel 8, and into conduit 17.  Raw material fed through hopper 25 into pipe 24 via flap gate 26 is distributed into the gas flow stream in conduit 17 by baffle plate 41 and is carried into heat exchange separator 14. Raw material discharged from cyclone 14 into pipe 22 is carried by the gas flow into cyclone 13. Analogously the raw material passes through cyclones 12 and 11 and is finally fed into the rotary kiln in a heated condition through dust discharge pipe 19. Means are provided for removing and cooling the material rich in alkalies collecting in cyclone 3.  In an alternative embodiment, Fig. 3 (not shown), the gases from the kiln pass into a branched pipe, so that part of the exit gas passes directly into the preheating system and part is diverted through a cyclone for removal of alkalies and subsequently rejoins the bulk flow of the gas. This prevents too much heat loss from the exit gases.  The material on which the alkalies are precipitated may be used as a fertilizer.
