IPC: H01J17/06

Abstract: 1,233,568. Discharge lamps; cathode materials. PERKIN-ELMER CORP. 13 Sept., 1968 [14 Sept., 1967], No. 43739/68. Heading HID. A hollow cathode assembly for a discharge lamp for use in atomic absorption spectroscopy is formed by introducing metal for examination into a cup-shaped member the open end of which is partially plugged to leave a channel of reduced diameter communicating with the space at the bottom of the cup, and melting or sputtering the metal to coat at least a substantial part of that space. As shown, an apertured disc 20, Fig. 1-which may be formed of a stack of very thin washers-of the metal for examination is introduced into the copper cup 10, which is then plugged by the copper sleeve 30, whereafter initial use of the lamp causes sputtering of the disc material to form a layer 40, Fig. 2, over the surfaces 14 and 34, which may be curved rather than angled, to form a substantially spherical cavity. Alternatively, if the metal for examination is of low melting point, it may be coated over the surfaces 14 and 34 by either heating the cathode assembly or, if already assembled, operating the lamp while the cathode assembly or the lamp, respectively, is rotated about its axis. In this case the cup-shaped member should be of a material not alloying with but readily wetted by the metal for examination, e.g. when the latter is lead or tin, the member may be of iron or titanium respectively. Other metals for examination referred to are Y, U, Ho, Sm, Yb, Er, Gd, Dy, Tb, Nd, Ru and Pr.

Abstract: 1,238,506. Mixing fluids in conduits. DOW CHEMICAL CO. 25 July, 1968, No. 35618/68. Addition to 941,893. Heading B1C. The method of the parent application is modified by dividing the main stream into first, second, third and fourth partial streams from top to bottom and recombining them in the order of second, fourth, first and third from left to right as seen from the downstream direction. A suitable baffle has four channels 13, 14, 15, 16 which are elongated at their ends, the major axes of each channel being non coplanar at its opposite ends (as shown, differing by a right-angle), the ends of the baffle being of generally swastika-like configuration. Right and left hand baffles are not required, identical baffles being inserted into the conduit with successive baffles reversed end to end so that like ends 18 or 19 are adjacent but with their stream dividers in planes differing by a right-angle. In baffles for use in a conduit of circular cross-section, the ends of the stream dividers are notched to receive those of the adjacent baffle, the first and second ends of each baffle being differentiated and identified by the omission of a notch on each first end and the provision of a corresponding deeper notch on each second end, see Figs. 11-14 (not shown). Reference has been directed by the Comptroller to Specification 900,656.

Abstract: 1,250,405. Spray carburetters. AUDI NSU AUTO UNION A. G. Oct. 22, 1969 [Oct. 22, 1968], No. 51656/69. Heading F1B. A carburation system comprises an induction pipe of substantial length with a main carburetter at the upstream end of the pipe, the downstream end of the pipe being adapted for connection to an induction chamber of the engine, a throttle valve in the induction pipe, and an idling system in which fuel is mixed with air and passes through a mixture passage which is short in comparison with the length of the induction pipe and opens into the induction chamber at the downstream end of the induction pipe. A planetary piston engine 1 has two main inlet passages 4, both fed with mixture by a main carburetter having a float chamber 17 and separated from the engine by a long induction pipe 2. A separate throttle valve 5 is provided in each inlet passage 4. To avoid precipitation of droplets of fuel in the induction pipe 2 during idling, the idling system is separated from the main carburetter and is located near the induction chamber, e. g., in the cylinder block or cylinder head but preferably in a flange 3 containing the inlet passages 4. The idling system comprises a fuel pipe 10 communicating with the float chamber 17 or a separate float chamber and terminating in an idling fuel jet 11 at a chamber 9 in which the fuel is mixed with air supplied from one of the inlet passages 4 upstream of the associated throttle valve 5 via an air passage 8 calibrated at 8a to serve as an idling jet. From the chamber 9, separate idling mixture passages 13 each containing an idling mixture regulating screw 14 and leading to an idling inlet passage 6 associated with the respective main inlet passage 4. Extra air is supplied to each passage 6 from its associated main passage 4 via a passage 15 commencing upstream of the associated throttle valve 5 and containing an air regulating screw 16. Blow-back of fuel on occurrence of pulsation in the idling inlet passages 6 is prevented by a common non-return valve 12 or by separate non-return valves in the passages 13.
