Title: Temperature responsive actuating apparatus
IPC: F23N5/14
Filed: 1970-02-24
Abstract: 1307551 Measuring temperature electrically KANTHAL A B 24 Feb 1970 [24 Feb 1969] 8864/70 Heading G1N [Also in Divisions F4 G4 H1] A temperature responsive actuating apparatus includes a refractory silicide element i.e. a refractory metal with a silicide coating or a refractory metal silicide, wherein a silicide is a binary compound of silicon with a metal 13, having a positive temperature co-efficient of electrical resistance and an electromagnetic device 12 connected to the element so that in operation a sensed temperature in excess of a predetermined value produces a current flow through the device to maintain it at a first state whilst for a sensed temperature below the predetermined value the current maintains the device in a second state. The element is a molybdenum disilicide wire and i s connected in series with the device which is a solenoid-actuated valve which allows fuel to flow to a burner nozzle 16 when the element temperalure is maintained (above the predetermined value by the hot igniter 14. In another embodiment Fig. 2b (not shown), the device actuates an alarm (17) to indicate a flame-off condition when the @gniter temperature falls thereby causing the element temperature and resistance to fall. The volatage drop across the element may be measured directly Figs. 3, 4 (not shown), to indicate a flame on/off condition or as in Fig. 5 (not shown), the element and the device may be in parallel, the combination being in series with a resistance (19). To prevent high current levels through the device 12 due to an open circuit in the element, the device is fused (12A) Fig.6 (not shown). The embodiment of Fig.7 (not shown), utilizes an element in a Wheat stone bridge circuit with the device 12 across the bridge output terminals, a further modification Fig. 8 (not shown), comprising a second element in the bridge for ambient temperature compensation. In use as a burner control the device 12 is connected in series with a fuse 12A, a resistance igniter 31, for the pilot nozzle 32, and a further electromagnetic device 30. The element 13 is connected in parallel with the series combination of the fuse and device 12 and energy is supplied from a source 11. With no pilot flame the element is cold so the current flow through the igniter 31 is sufficient to heat it and also to switch the further device 30 to open a fuel valve in the supply line to the pilot nozzle. The pilot flame ignites, causing heating of the element of which the resistance increases so that it longer shunts the device to which is triggered to open the fuel valve in the line to the burner valve 16. Other applications of the apparatus include detection of flow blockage Fig. 10 (not shown), in a clothes drier and a refrigerator.

The cutting edge of at least one blade of shears &c. is convexly curved over a portion near the fulcrum the remainder of that edge being straight and the cutting edge of the cooperating blade being straight or convexly curved over a corresponding portion so that over that arc of opening during which the point of intersection of the cutting edges lies on the curved portion the angle of intersection between the cutting edges remains substantially constant. As shown, the cutting edges of blades 10 are recessed near the fulcrum 11 to form convex portions 10b, the angle of opening of the blades remaining substantially constant while the point of intersection of the cutting edges is on the part XY of the bisector 13 and being less than the angle of opening for straight edged blades 10c which intersect at W spaced farther from the fulcrum with consequent loss of mechanical advantage. Slipping of the material to be cut is avoided by forming the curvature so that the angle between the curved edge and the bisector is less than the friction angle for the material. In order to increase the rigidity of the blades they may be hollow forged as disclosed in Specification 756,928. According to the Provisional Specification toothed blade edges are provided as disclosed in Specification 706,296.

Title: Novel naphthalene derivatives and a process for the preparation of same
IPC: C07C45/00
Filed: 1955-04-01
Abstract: The invention comprises compounds of the general formula <FORM:0768760/IV(b)/1> where R is formyl or methyl.  The compounds are prepared by formylating a 1-hydroxy-8-alkoxy-naphthalene by treatment with dry hydrogen cyanide and gaseous hydrogen chloride in the presence of zinc chloride, followed by hydrolysis of the aldimine hydrochloride so obtained to give the compound of the above formula where R = formyl.  This is catalytically reduced by hydrogenation in the presence of a copper/chromium oxide catalyst at elevated temperature and pressure to give the compound of the above formula where R = methyl.  In examples, (1) dry gaseous hydrogen chloride is passed through a solution of zinc chloride, 1 - hydroxy - 8 - methoxy - naphthalene and anhydrous hydrogen cyanide in dry ether, the ether decanted from the aldimine-hydrochloride precipitate which is then hydrolysed with water and the solid 1-formyl-4-hydroxy-5-methoxy-naphthalene recrystallized from benzene/petrol; (2) a methanolic solution of 1-formyl-4-hydroxy-5 - methoxy - naphthalene and a copper/chromium oxide catalyst are hydrogenated, the catalyst removed, the crude product isolated by distillation and recrystallized from methanol to give 1-methyl-4-hydroxy-5-methoxy-naphthalene.
