Title: A device for supervising and indicating breathing
Inventor: VIERLING OSKAR
IPC: B01J31/16
Filed: 1969-05-30
Abstract: 1,215,904. Monitoring breathing. O. VIERLING. 30 May, 1968 [20 July, 1968], No. 27497/69. Heading A5K. [Also in Division G1] In a device for supervising and indicating breathing, a probe 1 is inserted into the nose, and variations in air flow during breathing are converted into a sinousoidal voltage appearing at the tapping point of two N.T.C. resistors 4, 5 mounted in a measuring chamber 2. This signal is amplified at 6, rectified at 8, and during breathing a capacitor 11 is charged, capacitor 11 being discharged during the pause between breathing. If the voltage on capacitor 11 falls below a threshold value set by circuit 13, e.g. a Schmitt trigger, this circuit 13 activates a generator 14 connected to a loudspeaker 15 and a relay 16 which closes its switch 17 to actuate further alarm systems. Both the intensity and frequency of breathing may be indicated on meters 9 and 7 respectively and may be recorded. Resistor 10 is adjustable to set the discharge rate of capacitor 11 and thus the permissible pause between breaths before the alarm is actuated. The amplifier is adjustible for the intensity of breathing.

Title: Improvements in Electric Temperature Controls
Inventor: THOMPSON GEORGE CAVELL
IPC: H05B1/02
Filed: 1965-06-29
Abstract: 1,151,503. Thermal switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 21 June, 1966 [29 June, 1965], No. 27529/65. Heading H1N. A thermostat for an electrically heated vessel 1, or oven, or hot- or boiling-plate 3, comprises the additive combination of a linearly expansible current heated strut 9a with an expansible capsule 7 connected by a capillary tube 8 to a temperature sensing element 2 responsive to the temperature of the vessel, or hotplate, &c., the combination being arranged to actuate a microgap switch 10 in series with the heating element, the current through which also passes through and heats the strut 9a which therefore "cycles" switch 10. The capsule 7 acts at A on a floating lever 25 supported at B, and a part C of the lever acts on the strut 9a. A manually adjustable cam 26 operates on the lever at D either to provide an "off" position or to select the temperature at which the vessel, &c., is controlled. Operation of the cam causes the lever to pivot about axis BC to move A and thus vary the amount of expansion of the capsule necessary to open the switch. Initially, switch 10 is closed to deliver full power. Expansion of capsule 7 acts on the lever at A to pivot it about axis BD; since expansion of the capsule is added to that of the strut, the switch opens at a temperature lower than the one selected by the cam. As the temperature of the vessel, &c. rises, capsule 7 expands and proportionally effectively reduces the setting of the device to reduce the power to that necessary to hold the vessel &c. at the selected temperature. The parts 2, 4, 7, 8, 9a are identical in structure to corresponding parts in Specification 995,237.

Title: Manufacture of a new imidazoline
IPC: C07D413/06
Filed: 1948-02-12
Abstract: 2 - [Phenoxazinyl - (N) - methyl] - imidazoline and its salts are made by condensing reactive esters of 2-oxymethylimidazoline with phenoxazine or its N-metal derivatives (e.g. sodium).  The reactive ester may be a halide or alkyl- or aryl-sulphonate, preferably in the form of a salt.  A diluent and/or condensing agent may be present. The product forms salts with acids such as hydrochloric, sulphuric, phosphoric, acetic, methane sulphonic and toluene sulphonic.  The example shows the reaction between phenoxazine and 2-chloromethyl-imidazoline hydrochloride.  According to the Specification as open to inspection under Sect. 91, the phenoxazine nucleus may contain substituents such as methyl, ethyl, methoxy, ethoxy, propyloxy, butyloxy, benzyloxy, acetoxy, benzoyloxy, amino or nitro groups or halogen atoms.  The imidazoline nucleus may also be substituted, e.g. with methyl, ethyl or propyl groups.  An alternative method of preparation is to react a phenoxazinyl-(N)-acetic acid or derivative thereof with ethylene diamine or a substituted ethylene diamine.  Suitable acid derivatives are imidoethers, imidohalides, thioamides, thioimidoethers, amides, esters, halides, amidines and nitriles. The acid derivative may be formed in situ, e.g. a thioamide may be made from the nitrile and hydrogen sulphide, and the latter in turn may be formed from carbon disulphide, phosphorus pentasulphide or an alkali, ammonium, iron or aluminium sulphide with water.  The alkylene diamine may be used as a salt or as a derivative such as N : N1-ethylene-urea.  The process may be carried out in two stages by first forming the acyl derivative of the alkylene diamine and then ring-closing it with a dehydrating agent such as calcium oxide.  Specifications 514,411 and 608,295 are referred to.  This subject-matter does not appear in the Specification as accepted.
