Title: Vane-type pump
IPC: F01C21/10
Filed: 1973-09-05
Abstract: 1429248 Rotary positive-displacement fluidmachines DANFOSSAS 5 Sept 1973 [10 Oct 1972] 41778/73 Heading F1F A sliding vane-type pump in which the vanes 14 bear against the internal surface 15 of a ring 16 surrounding a rotor 12, the ring being rotatably adjustable about an axis N offset from the rotor axis M, and the surface 15 being formed over parts C, B and A, D of its surface as an involute of a circular evolute, the centre of the evolute being coincident with the axis N and its radius being  equal to the distance NM. By this means rotation of the ring 16 from the position shown in Fig. 1 will adjust the delivery of the pump, but for all adjusted positions of the ring, the portion CB of the surface 15 will for practical purposes have its centre of rotation at the rotor axis M thus minimizing axial movements of the vanes 14 at the part of their cycle in which they are subject to pressure differences between the inlet 3 and outlet 2 of the pump and thus minimizing wear in these parts. The surface 15 of the ring 16 is composed of the two involute portions CB and AD and in the remaining parts of transition curves which may be circular or formed as involutes of secondary evolute circles. Rotation of the ring 16 within the pump casing 1 displaces the centre point O of the surface 15 from coincidence with the axis M to either provide greater pump delivery or delivery in the opposite direction. The vanes 14 are pressed outwards by centrifugal force independently of the pump fluid by the provision of radial channels in the vanes 14 communicating with inlet and outlet of the pump.

Title: An impulse transmitter
IPC: H04M1/34
Filed: 1964-10-19
Abstract: 1,020,277. Impulse transmitters. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 19, 1964 [Oct. 17, 1963], No. 42615/64. Heading H4K. In an impulse transmitter in which impulses are transmitted during the return motion of the dial, the impulsing contacts are short-circuited before the dial reaches the home position. By completing the transmission of an impulse train, for a time at least equal to that of one impulse, before the home position is reached, a correct interdigital pause is ensured and the removal of the short-circuit across the speech circuit at the home position does not result in the exchange equipment interpreting any pulse so produced as part of the impulse train. When the dial (not shown) is wound up in the direction U, a cam 6 and an eccentric 8 which is frictionally coupled to the shaft on which cam 6 is mounted are caused to rotate in the same direction. The eccentric causes lever 7 to adopt the position shown in full lines whereat impulsing contacts 2, 3 move in unison in dependence upon cam followers 5, 4. Contacts 14, 15 are closed when abutment 13 is moved away therefrom during wind-up and hence short-circuit the speech circuit. During the return motion lever 7 moves into the dotted position where it engages contact 3 and thus allows the impulsing contacts to open and close in dependence upon the rotation of the cam 6. (Due to the eccentric, contact 3 in fact moves " upwards " when the contact 2 moves " downwards " under the influence of the cam). When the abutment 13 returns to position B it engages lever 7 and drives the latter to its inoperative position. The arrival of the abutment at the home position reopens contacts 14 and 15.

In a system for measuring the transmissivity of a sample, e.g. the atmosphere, a first light source transmits light to a first detector along a path including the sample and to a second detector along a reference path and similarly with a second source which affects both the second and first detectors. The outputs of the detectors are compared to provide a measure of the transmissivity of the sample. As shown, sources 1a, 1b which are luminescent diodes supplied at different frequencies by oscillators 2a, 2b illuminate photodiodes 5b, 5a along paths 6a, 6b respectively. The photo-diodes 5a, 5b are also illuminated along optical fibre paths 7a, 7b by sources 1a, 1b respectively. The resulting signals are amplified at 8a, 8b and supplied to discriminators 9a, 9b; 10a, 10b which provide four signals A, B, C, D for unit 15. The transmissivity of the sample is determined from the ratio B Î C / A Î D. The equipment at the ends of the transmission path is constructed as a unit, Fig.2, and comprises a metal tube 21 with a luminescent diode 1 mounted at the focus of lens 3. The detector is a photo-diode or phototransistor mounted at the focus of parabolic mirror 4. An optical fibre path 23 transmits a constant portion of the transmitted radiation direct to the detector. A colour filter 22 is provided to shield the detector and the whole assembly is mounted in a housing to protect it from solar radiation and weather. In a modification discrimination between the output signals is provided by pulsing the light sources and using synchronously operated gates to analyse the detector outputs and provide the A, B, C, D, signals, Fig.3 (not shown). Alternatively polarizing filters can be provided in the light paths that pass through the sample, Fig.6 (not shown). In a further embodiment, Fig. 5 (not shown), only a single path through the atmosphere is provided between a first light source and first detector. The paths between the second light source and first and second detectors and the first light source and second detector being provided by optical fibre paths. It is stated that the positions of the sources and detectors can be inter-changed and the source could comprise a coherent light source or filament or flourescent lamps or a discharge tube.
