Title: Improvements in centrifugal pumps

Abstract: 478,862. Centrifugal pumps. LABOUR, H. E. Feb. 16, 1937, No. 4682. Convention date, Dec. 29, 1936. [Class 110 (i)] A self-priming centrifugal pump, with an intake trap 9 and discharge separator 16 forming a chamber for retaining sufficient liquid for priming, has a single opening 43 between the impeller casing 16a and the separator 16 serving solely as discharge when the pump is supplied with liquid, but during starting serving also for the re-entry of priming liquid from the discharge. The volute 38 extends into the separator 16 to form directing channels for the re-entering streams. The volute has a cut-off surface 52 which may extend the full distance between adjacent blades. When the pump is running full, the volume of discharge prevents re-entry.

Title: Mechanism for speed reduction and stopping the film drive for use in cinematographic projectors
IPC: G03B1/22
Filed: 1974-02-01
Abstract: 1423943 Cine projectors BENCINI SpA 1 Feb 1974 [15 Feb 1973] 04700/74 Heading G2E A mechanism for controlling the film drive in a cinematographic projector comprises a flexible cam rod s displaceable between three operating positions, in one of which the drive is at normal speed, in the second at reduced speed, and in the third the drive ceases. The drive is effected by a - claw n on a pivot 4, the free end na of the claw engaging in the perforations of the film, which moves in the plane of Fig. 2. A first rotary cam W having a sloping face engages and reciprocates the claw perpendicular to the plane of Fig. 2, i.e. perpendicular to the path of film travel. A second rotary cam 3 has a profile such that claw n is reciprocated in a direction parallel to the film path. These two reciprocating motions control the intermittent engagement and driving of the film by claw n. Cam W is driven by a pinion pa mounted on the same spindle o. At its other end this spindle carries a pinion d engaging with a gear wheel r having a cam face cr. The cam rod s has a tapered intermediate section sr, an upper offset section sv and a lower broadened section so. A pair of push rods 1, 10 are mounted so that they can slide axially. When rod s is in its intermediate position the reduced central section sr does not engage either push rod, and the film is driven at normal speed. When the rod is displaced to its upper position, the broadened section so engages both push rods. Rod 10 is engaged and reciprocated by cam face cr, which motion is accordingly transmitted to rod 1 also, since the rod s is flexible. This displaces the free end na of claw n so that the claw is disengaged from cams W and 3 once for every two revolutions of the cams. Thus a reduction in film speed is obtained. When rod s is displaced into its lower position, offset sv engages rod 1 and pushes the claw n permanently out of engagement with cam W. Rod 10 is not engaged at all, so that it remains inoperative. Thus the movement of the film is stopped.

Title: Thermal power plant
IPC: F02C6/18
Filed: 1973-01-30
Abstract: 1416238 Gas turbine plant ATOMENERGI AB 30 Jan 1973 4724/73 Headings F1G and F1Q The invention relates to a gas turbine plant in which air is stored under pressure in an underground chamber, air being taken from the chamber at peak-load periods and supplied thereto during non-peak-load periods. The plant comprises a multi-stage air compressor 4 with inter-stage and after-cooling, being driven by an electric motor 5 during non-peak-load periods to supply air under pressure to an underground chamber 1. The chamber 1 is connected to an upper water reservoir 3 by a duct 2 whereby the chamber is pressurized. At peak-load periods air under pressure is taken from the chamber 1 and passed through line 24 to a pre-heater 13 then to a combustion chamber 6, the combustion gases passing through a plurality of turbine stages with inter-stage heating, the turbine driving an electric generator 8. A pump/turbine assembly 40 is disposed in the duct 2, the assembly being driven by an electric motor 55 through clutch 52 during peak-load periods whereby the pressure of the water in the duct and thus the pressure of the air in the chamber 1, is increased compared with the static pressure that would be obtained due to the difference in levels between the water reservoir and the compressed air chamber. During off-peak periods when the air chamber is being charged and water is being discharged from the air chamber 1 through the duct 2 to the water reservoir, the assembly 40 is driven as a water turbine, the turbine driving an electric generator 56 through clutch 53. A flowmeter 23 is disposed in duct 2 and is connected to a shut-off valve 12. The heat removed from the air during compression in the inter-stage and after-coolers 9 is utilized by passing the heated coolant to a user device 31, a heat accumulator 30 being provided in the system. In Fig. 2 the duct 2 is divided into two paths in parallel 21, 22, a pump 10 being provided in one path and a water turbine 11 in the other. The pump 10 is connected through clutch 43 to the gas turbine 15 during peak-load operation, whereas the water turbine 11 is connected through clutch 42 to the compressor 4 or to an electric generator 14 during off-peak operation when water is being forced up through the duct 2 to the reservoir 3.

Abstract: 234,541. Cannon, A. H. Sept. 27, 1924. Catches, automatic; fastenings operating electric alarms; locks, pin-key.-A fastening for sliding sashes comprises a spring or gravity-actuated catch o pivoted at p in the case d in the sash frame and adapted to engage one of a number of holes in the upper sash in such a manner that the sash can be closed automatically but cannot be opened without the use of a key. The catch is secured in its engaging position by a projection it on a cylinder s which can be turned by means of a. key either to an intermediate position or so as to cause the projection u to engage the heel w of the catch to withdraw the latter, and, if desired, hold it in its retracted position. The catch when withdrawn may contact with a spring 6 forming part of an electric bell circuit, so that, if the switch in the circuit is closed and an unauthorized attempt is made to withdraw the catch, the circuit is completed and the alarm given. When applied to the lower sash the fastening is inverted. Reference has been directed by the Comptroller to Specifications 26486/04 and 17986/06.
