Title: Improvements in indicating mechanism for measuring instruments
IPC: G01L7/00
Filed: 1927-11-21
Abstract: 280,966. Pauliin, J. G. Nov. 22, 1926. [Convention date]. Barometers.-The movement of a barometer diaphragm box is transmitted to an indicating pointer by a system off flexible members, bands. strings &c. influenced by spring tension and inserted between two parts adapted to be relatively displaced, the axis of the pointer being arranged parallel to the direction in which the system of flexible members is stretched between the points of attachment. The diaphragm box 2 is attached to a base plate 1 and is acted upon by the lower shank of a spring 4 to which it is secured by a nut 3, the upper shank being clamped in a slot in a bar 6, the position of which may be regulated by set screws for regulating the tension of the spring. On both sides of the nut 3 the spring 4 is provided with projections 7 to which the lower ends of two helical springs 8 are attached, the upper ends being secured to a yoke 9 connected with a nut 10 through which passes a micrometer screw 11. The nut is prevented from rotating by a yoke 14 embracing a post 15. The lower shank of the leaf spring 4 is provided with an extension 18 playing between limiting stops 18' and this extension is provided with lugs 35, 35' to which are connected the lower ends of pairs of flexible bands 19, 20, 19', 20' bent to an obtuse angle, the upper ends being connected to a fixed plate 21. The points of attachment a, a', b, b<1> are all in a plane at right angles to the plane of symmetry of the instrument. The apexes c, c' of the connections are connected by bands 22, 22<1> to a transverse pin 23 secured to a vertical pointer spindle 24 the ends of which are connected to the free ends of helical springs 25, 26 attached to the frame. The spindle 24 carries the pointer 27. The rear end of this painter is bent upward and around the edge of a circular plate carrying the scale 16 and in addition a short scale 28 for the pointer 27 which at its other end carries a counter weight 29. Normally, the pointer 27 stand's at zero in the middle of the scale 28. On the atmospheric pressure varying the lower of the diaphragm box moves, and with it the pointer 27. This pointer is brought back to zero by turning the screw 11 so that the tension of the springs 8 is varied to restore the diaphragm box. The movement of the screw and hence the variation a pressure may be read off by the pointer 17 on the scale 16. A modification is described in which the apexes c, c' are connected directed to a thin plate carrying the pointer 27 which is thus directly carried by the band system.

Abstract: 505,379. Liquid-meters. ALFA-LAVAL CO., Ltd., and CORDEROY, N. Nov. 17, 1937, No. 31605. [Class 143] In a device for measuring milk or other liquid, of the kind in which a counter or indicator is actuated by the oscillation of a pair of buckets 7 mounted below one or more apertures through which the liquid flows to fill the buckets alternately as they rock, the aperture, or each aperture, is provided with a valve seat on whch rests a valve having a lower part projecting through the aperture and adapted to be engaged directly by one or more members attached to the buckets so as to raise it when either bucket is in the filling position. In the flow recorder for a milking- machine shown, the milk flows from an upper compartment 2 through a pair of sleeves 5 into one or other of the tilting pair of buckets 7 mounted on a knife edge 6 in the lower compartment 1. A ball-valve 14 normally closes the reduced lower end of the sleeve and projects below it so that it is engaged and raised by one of a pair of rods 15 extending across the buckets when either bucket is in filling position. The movements of the buckets are limited by adjustable stops 8, and are transmitted to the counter by a striker 10 engaging a toothed wheel 11 on a transmission shaft. Specification 440,270, [Group XXIX], is referred to.

Abstract: 811,680. Coating surfaces with preformed sheets. NEUCHATEL ASPHALTE CO. Ltd. Sept. 24, 1956 [Nov. 7, 1955], No. 31752/55. Class 93 [Also in Group X] A method of waterproofing buildings comprises applying (1) a layer of bitumen to the surface to be waterproofed, (2) a layer or layers of glass fibre tissue over the bitumen, and (3) a further layer of bitumen, with or without further alternating layers of bitumen and glass fibre tissue. A layer 5 of hot molten bitumen is spread over the surface and a sheet 6 of glass fibre tissue is immediately applied over the hot bitumen so that it becomes embedded in the bitumen, and a second layer of hot bitumen is spread over the glass fibre sheet, followed if desired by further alternating layers of glass fibre sheet and hot bitumen. The bitumen may contain an inert filler such as powdered limestone. The final layer of bitumen may be given a coating 7 of sand, grit, chipping or other material. The invention is applicable to roofs, basements foundations and horizontal, inclined and vertical surfaces. The bitumen can be applied by spray gun using heated lines.

Abstract: 411,817. Photo-mechanical printing- surfaces ; photographic processes. BROWNE, T. C., 170, North Lincoln. Street, Hinsdale, Illinois, U.S.A. Nov. 10, 1932, No. 31818. Convention date, Nov. 17, 1931. [Class 98 (ii).] Printing-plates or other articles such as artificial leather having a grain or relief upon the surface are formed by gelatinizing a layer of rubber &c. from a dispersion thereof against a hydrophilic colloid rendered non-uniformly absorptive. Fig. 1 shows a cross-section of the printing-plate and a bichromated gelatine plate used in the process. The gelatine plate is first exposed under a negative and then washed and partially dried and immersed in latex as by being laid in a tray into which latex is poured. Owing to absorption of water by the unexposed parts 18 of the gelatine layer 11, a layer 12 of rubber gelatinizes against the gelatine layer 11, the upper surface of this rubber layer 12 being evened out if necessary by pouring over it when dry a second coat 13 of latex. A backing consisting of a metal plate 16 (which may be of wire netting) and a sheet 14 of semi-cured rubber is pressed upon the upper surface of layer 13 and secured by curing in sulphur chloride vapour or by cementing if vulcanized latices have been used. Fig. 2 shows a completed plate with the gelatine removed from the rubber layer on the backing 16. Fig. 6 shows a plate with the areas between the raised portions 31 of rubber filled with exposed bichromated gelatine to form inkrepelling surfaces.

Title: Improvements in and relating to the production of hot gases under pressure by means of a gas turbine
IPC: F02C3/22
Filed: 1939-12-12
Abstract: 533,893. Gas turbines; blowers. AKT.-GES BROWN, BOVERI & CIE. Dec. 12, 1939, No. 32050. Convention date, Dec. 27, 1938. [Class 110 (iii)] A constant pressure gas turbine installation provides heated compressed air for external uses, e.g. hot blast, and is regulated in response to the temperature and quantity of the air being delivered. In some cases pressure instead of quantity is the second controlling characteristic. A compressor 2 delivers air to a heatexchanger 6 and part of the air goes to a burner 8. The gases from the combustion chamber 4 are mixed with a second, part of the air passing along a line 9 and drive the turbine 1. A third part of the compressed air passes through a heat-exchanger 5 and is delivered to the hot-air user. A thermostat 11 controls a valve 10 which, when the temperature at 11 falls, opens to increase the air passing directly to the turbine. This causes the quantity of air passing through the heat-exchanger to fall, so securing an increase in temperature and, at the same time, the quantity meter 12 operates a valve 13 to increase the fuel gas supplied by the blower 3. In place of a throttling valve 10, an auxiliary turbine coupled to the turbine 1 may be used, the nozzles of the auxiliary turbine being controlled by the thermostat 11. In place of the throttle control 13, the blower 3 may be driven by a separate motor controlled by the quantity meter 12. In place of the valve 10, the air suppy in the line 9 may be controlled by selective tapping of the compressor 2. The controls of the devices 11 and 12 may be interchanged.
