Title: Improvements in or relating to light diffusing glasses
IPC: F21V5/00
Filed: 1933-12-01
Abstract: 424,800. Light-diffusing refractors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BEGGS, S. S., c/o General Electric Co., Wembley, Middlesex. Dec. 1, 1933, No. 33788. [Class 75 (ii)] Relates to the control of light distribution by means of diffusing-glasses more particularly in connection with a linear light source. Fig. 1 shows light paths through a diffusing-glass, which may be a prismatic flute or a cylindrical fitting, such as shown in Fig. 2. One face of the diffusing-glass is so shaped that most or the whole of it is divisible into portions A and B (not indicated in the drawings), such that, when a light beam 6-14 is incident on this face in a plane in which diffusion takes place and parallel to a line 6-6, called the axis of the glass, the light rays 6-8 incident upon A emerge directly, and the light rays 10-14 incident upon B are totally reflected and emerge subsequently at a portion C (not indicated in the drawings) of the face of the glass, which portion C includes substantially all of A and may include some of B, the two beams incident on A and B being so distributed after emergence that there is substantially no gap between them. The glass may be a segment of a cone or cylinder of which a section in a plane of diffusion is shown in Fig. 1. The face on which the beams leave the glass comprises the plane sides 1-2, 3-4 each forming an angle # with the axis 6-6, and the apex 1-5-3, which is a segment of angle 2 # of a circular cylinder. As shown, #+#=90‹, the sides being tangential to the apex. The angle # is at least as great as the critical angle for glass, <i>c. In the form shown, with 0 greater than <i>c, intermediate rays such as 9 may be totally reflected so as to return towards the source. To reduce loss due to this, #=<i>c and # + # is less than 90‹. Numerical examples are given. As shown in Fig. 2, a fitting 2 for use with a linear light source 1 is composed of a plurality of elements or flutes 5 having the form shown in Fig. 1, with or without directional prisms 4. The individual diffusing-glass flutes may alternatively have the sides 1-2, 3-4, slightly curved, and the apex of section other than circular. The sides may be prolonged beyond the base 2-4, as shown in Fig. 1. Specifications 19185/93, [Class 75], and 408,419 are referred to.

Title: Rotary fluid meter
IPC: G01F15/06
Filed: 1957-11-01
Abstract: 825,029. Rotary meters. ROCKWELL MANUFACTURING CO. Nov. 1, 1957 [Nov. 14, 1956], No. 34133/57. Class 110 (2). A meter of the inclined-disc type is provided with magnetic means for controlling the nutating movement of the disc 88. In Fig. 1 the disc 88 contains a cylindrical bar magnet 96 which is provided with a corrosion-preventing cap 98 of non-magnetic material such as plastic, synthetic rubber or the like. The magnet 96 functions both as the driving member of the magnetic coupling 28, interconnecting the measuring chamber unit 26 with the register 24, and as one element of a magnetic coupling guiding the movement of the disc 88. The register mechanism 24 is such as is described in Specification 733,381. A tubular support 104, of non- magnetic material, is secured to a casing 100 which is provided with a window 106. The top of the magnet 96 moves around a guide pin 122 but is biased by the magnetic attraction of a ring 118 of ferro-magnetic material. The magnetic attraction between a steel ball 124 and the upper end of the magnet 96 actuates the recording mechanism, in the chamber 100, by means of a crank 128. The meter casing is provided with a bottom frangible frost plate 16 having a liner 50. Liquid flows from an inlet 30, through a strainer 78 to the metering chamber, by way of a port 76, and is discharged through an outlet 79 into a chamber 60 having a delivery 62. The disc is formed of part-spherical segments 84, 86 and a circular disc 88, the parts being clamped together by a hollow bolt 90 of stainless steel. Fig. 2 shows another arrangement in which a second control ring 142, of magnetically-permeable material, is provided, and which attracts the lower end of the magnet bar 96<1>. A modified construction, Fig. 3, has a disc formed of hard rubber spherical segments 184,186 and an internally-reinforced disc 190. A stainless-steel shell 196 houses a bar magnet 198 and engages a coupling dog 200 fixed to the lower end of a spindle 202 which drives the recording gear mechanism 208. The movement of the nutating disc is secured by the interaction of the magnet and a ring 220 of soft iron or other magnetically-permeable material. The bottom of the casing 150 is closed by a frangible frost plate 230 having a corrosion-preventing metal lining 232. The casing parts are formed of bronze or suitable non-magnetic materials. The material used for the bar magnet 96 is made up of nickel, aluminium, cobalt and iron. U.S.A. Specifications 1,903,074, 2,129,143 and 2,826,069 also are referred to.

Title: Well cementing apparatus
IPC: E21B33/136
Filed: 1946-11-18
Abstract: 618,997. Well and borehole apparatus. DEHN, S. G. (Baker Oil Tools, Inc.). Nov. 18, 1946, No. 34142. [Class 85] Cement is positively prevented from passing beneath a casing string c during cementing of such a string in a borehole by a tool secured to the lower end of the string. The tool comprises a ported tubular member 11 having secured therein, between a shoulder 19 and a cement nose 20, a tubular body 13 having a centre portion 16 of reduced diameter so that an armular chamber 25 is formed between the body 13 and the member 11. Mounted in this chamber 25 is a rubber skirt 26 forming a non-return valve to the ports 24 in the body 13. During operations prior to cementing, fluid flow through these ports 24 is prevented by a sleeve 27 held in position by shear screws 28, the fluid passing down through the tool and out into the borehole through a non-return valve 22. When it is desired to commence the cementing operation, a ball 41 is passed down the casing string on to a seat 42 on the sleeve 27 so closing the passage through the tool. The fluid pressure in the casing is increased causing the shear screws 28 to yield and forcing the sleeve downwards to uncover the ports 24 so that the cement can be forced down the string C out into the space between the casing and the borehole through the ports 24, past the non-return valve and through the ports 12. When the screws shear, a bolt 33, attached to the head of one of them and which bears against the member 11 of a spring steel band, is forced outwards so allowing the band to fall clear and release an annular barrier formed of spring- biassed petal segments 31. This barrier closes the space between the member 11 and the borehole, so preventing any cement grout passing beneath the tool.
