Title: Improvements relating to the clothing or encasing of girders, beams, stanchions and the like
IPC: E04B1/94
Filed: 1940-02-02
Abstract: 538,483. Casings and coverings for girders.; moulding plastic substances. MORTON, B. Feb. 2, 1940, Nos. 2043/40 and 2254/41: [Class 20 (iv)] [Also in Group V] A method of clothing or encasing the flanged elements of a steel frame for a. building consists in supplying blocks which are so shaped that they can be passed over the flanges and then partly rotated to interlock them with the flanges, the blocks being arranged in contact with one another along the flanges with a part of each one overlapping the adjacent block. The blocks may be cast in concrete or they may be made of other suitable material. Each block B, Figs. 1 and 5, comprises a base 1 of rhomboidal shape, and two upper parts 2, 3, which are separated by a gap slightly wider than the width of the flange of a girder A. Each part 2, 3 is undercut at 5 to a shape corresponding to the edge of the flange. When applying a. block to a girder, the flange passes between the parts 2, 3. The block is then rotated in the direction of the arrow x until the parts 2,. 3 meet the web, and the block is then moved along the flange into contact with the next block. Other blocks may be placed on the blocks B to complete the encasing of the girder, and filler pieces may be added if required. The blocks are grouted or cemented together in known manner. The blocks may be reinforced by bars 9 and the parts 2, 3 may be rectangular or triangular in shape. Some of the blocks may have bases 1 with sides that are arcs of circles so that they may be rotated for removaleven when assembled side by side. When made of concrete they may be cast in a mould composed of sides 11, Fig. 21, and ends 12 slotted to receive a half joist 13. Sheet metal partitions 15 are placed in the mould and separated by wooden spacers 14.

Abstract: 876,292. Generating random-noise signals. DOUCE, J. L., and WEST, J. C. Jan. 15, 1959 [Jan. 22, 1958], No. 2131/58. Class 40(5) Relates to a generator for producing randomnoise signals in a frequency range extending from zero to a few cycles per second for testing servomechanisms &c. As shown a thyratron 1 surrounded by a permanent magnet 2 generates random noise over a range of 100 to 1,000 cycles per second which is amplified by the pentode 9 and supplied via a cathode-follower 19 to a high pass filter 24, 25, 27, 28. The output of the high pass filter is supplied via a cathode-follower 26 to a low pass filter 30, 31, 33, 34, and the two filters together constitute a band pass filter with a mean pass frequency of about 230 c/s. and a two to one frequency ratio between the upper and lower pass frequency limits. The resultant signals are supplied via a cathode-follower 32 to a pentode amplifier 36 whose output is supplied through a cathode-follower 44 to diode clippers 48, 49 and by this means the frequency spectrum is extended down to zero frequency. The output of the clipping circuit is fed via a cathode follower 56 to a low-pass filter 58 to 64 which removes all the signal components above about 30 c/s. and the output from the filter is fed through a cathode follower 65 to the output terminal 70.

Title: Process and Apparatus for Separating Air or Gases from Liquids.
IPC: F24D19/08
Filed: 1917-02-15
Abstract: 104,183. Rasmussen & Ernst Ges. Feb. 16, 1916, [Convention date]. Liquid and gases, separating.-A separation is effected between liquid rich in air and liquid poor in air by causing the lighter liquid containing much air to rise higher than the liquid poor in air owing to their different velocities. Liquid containing air enters a chamber a by a nozzle d, the heavier liquid escaping by a pipe k, while the lighter rises so that a " neutral zone" is formed which facilitates the separation of air. At the top of the chamber a there may be arranged a number of " cells" e. The separated air, with any liquid particles associated with it, passes through a narrow opening l into a chamber m, from which the air escapes at o and the liquid at n. One or more additional chambers may be arranged similar to a, as shown in Fig. 2, in which case the lighter liquid and air from the chamber a pass by a nozzle f into the second chamber b furnished with cells g. The air escapes as before, and the liquid is returned by a pipe h to the chamber a through a nozzle i. Reference has been directed by the Comptroller to Specifications 1437/80, 17158/87, 20468/00, 6011/06, [Class 46, Filtering &c.], and 18165/14.
