Title: Improvements in clamps for rock drills
IPC: B23Q1/28
Filed: 1924-05-20
Abstract: 229,537. Veasey, J. H. May 20, 1924. Percussive tools.-The conical surface 11 of the foot of a rock-drill cradle is held between plates 9 retained by cross pins 12 in a head 10 which is pulled down by bolts 24 bearing on a pressure plate 16.

Title: Improvements in or relating to periodic sampling and testing apparatus
Inventor: PAGE GEORGE CLIFFORD
IPC: G01N35/00
Filed: 1953-05-05
Abstract: 798,817. Photo-electric indicating systems. THOMPSON-KENNICOTT, Ltd., J. Aug. 5, 1954 [May 5, 1953], No. 12520/53. Class 40 (3). Apparatus for periodically sampling and testing a liquid comprises means for periodically delivering samples of the liquid to be tested to a point where a colorimetric reagent is introduced by siphon action and a photo-cell tests the light absorption to effect an indication or control when a sample has a light absorption outside predetermined limits. The invention is described with reference to testing the effluent water from a cation or anion exchange unit. Thus magnesium ions may be indicated by adding solution of Titan yellow and caustic soda when, if magnesium is present, the effluent turns pink; ammonium ions may be detected by the use of a Nessler solution and silica will cause an effluent to turn yellow if ammonium molybdate and sulphuric acid solution are added. As shown, part of the effluent from an ion exchange unit flows into a chamber 1 having an overflow pipe 3 which maintains the level in the chamber constant. The chamber communicates with a measurement chamber 5 from which the liquid is drained by means of a periodically operated valve 8 by motor-driven cams and relays into a venturi chamber 9. As the fluid enters the venturi chamber the vacuum created therein syphons reagents from measuring chamber 13, 13a which are initially filled by forcing compressed air into reservoirs 12, 12a. The sample and reagents flow to a mixing chamber 10. A valve 19, also controlled by motor-driven cams and relays, allows the liquid to flow to chamber 20 where photo-electric examination takes place and subsequently drains chamber 20. Circuits.-The intensity of the coloration of the samples may be measured by means of a pair of photo-cells connected in series opposition with each other and having a resistor in the circuit. Both cells are illuminated from a common source but one receives light which has passed through the sample while the light reaching the other cell is adjusted by an iris shutter. The apparatus is set up by means of the iris shutter so that the two cell outputs, as determined by the potential at their common terminal, are equal. Discoloration of the sample changes the output of one cell and the change of potential referred to above may be used to operate a signal to shut down the ion exchange unit or start an automatic regeneration cycle.

Title: Process for making diatomaceous earth products
IPC: C04B28/08
Filed: 1934-05-02
Abstract: Refractory materials are made by crushing and mixing diatomaceous earth and slag, incorporating calcium carbonate and sodium chloride with the mixture to form a binder, moistening the product, pressing into the required shape, and subjecting the compressed mass to heat treatment to bind the constituents together and to evaporate excess moisture.  Glucose is preferably incorporated as a temporary binding agent serving to keep the compressed mass in shape before the permanent bonding is effected. According to an example, 90 to 95 per cent of crushed slag is mixed with 10 to 5 per cent of calcium carbonate, the mixture incorporated in a proportion of 10 to 15 per cent with 90 to 85 per cent of calcined diatomaceous earth, approximately 5 per cent of the total of sodium chloride and 2 1/2 per cent of water being finally added.  The pressed mass in the form of blocks is heated first with steam under 100 pounds pressure for about 8 hours to affect the bonding, and finally subjected to dry heat to evaporate excess moisture.
