Title: Improvements in apparatus for measuring the flow of liquids
IPC: G01F1/00
Filed: 1934-11-16
Abstract: 447,682. Indicating, recording, and integrating apparatus. KENT, Ltd., G., 199, High Holborn, London, and LINFORD, A., Biscot Road Works, Luton, Bedfordshire. Nov. 16, 1934, No. 33085. [Class 106 (iv)] An instrument for measuring the flow through a Venturi flume comprises a member moved in proportion to a function of the difference of head between a point upstream (h1) and a point at the flume throat (h2), another member moved in proportion to the head at one of these points, and a third member moved in proportion to the product of the movements of the first two members, one of the first two members being coupled to one arm of a lever, the other of the said first two members being coupled to its fulcrum and the third member being actuated by the other arm of the lever. In the embodiment described, the product obtained is proportional to h2#h1-h2 . A float 1 measures the depth of water h1 on the upstream side of a Venturi flume and a float 2 measures the depth h2 at the throat of the flume. The movements of the floats are transmitted to a differential mechanism 3, a wheel 4 of which is moved proportionally to h1-h2. This movement is given to a cam 5 on which bears an arm 7 moved proportionally to #h1-h2, the motion being transmitted to a rack 9 integral with a plate carrying the fulcrum 22 of a lever 20. A segment 12 connected to the differential mechanism is moved proportionally to h2 and causes a carriage 13 to slide horizontally. A vertical member 17 is secured to the carriage 13 and is engaged by rollers 18 on a link 16. The other end of the link has rollers engaging the lever 20, the intermediate part of the link being guided by rollers 19 on the plate integral with the rack 9. Another link 24 guided at 25 engages the lever 20 by means of rollers 23. The horizontal movement of the link 16 and the swinging of the lever 20 about its fulcrum 22 are determined by the value h2 and the distance between the fulcrum 22 and the link 24 are determined by the value #h1-h2, the movement of the link 24 being proportional to h2#h1-h2. This movement is transmitted to a recording pen 30 by a roller 26 engaging a cam 27 and also to an integrator comprising a counter 28 moved over a disc 31 driven at a constant speed. Specification 328,659, [Class 106 (iv)], is referred to.

Title: Activation of bleaching clay
IPC: B01J8/24
Filed: 1957-10-24
Abstract: Clay is activated by mixing it with 25-60% by weight of water and 10-50% by weight of sulphuric acid and heating for a time and at a temperature sufficient to activate the clay and reduce the water content to a maximum of 10% by weight.  This heating is preferably carried out for 10-250 minutes at a tempera <PICT:0856756/III/1> ture of 100-400 DEG C.  The process may be carried out continuously by passing the mixture, preferably in the form of pellets, through a heating zone at 100-200 DEG C., the residence time in the zone being 10-40 minutes.  The heating may be effected in a spouting bed column (Fig. 2) as described and claimed in Specification 801,315. In Fig. 2, a tower 1 contains a bed 2 of wet clay pellets.  Air enters through an orifice 6, forming a narrow column 7 in which the pellets are moving upwards to form a spout 8, the pellets outside said column moving downwards and inwards towards said column.  The activated clay leaves via pipe 4.  The activated clay may be employed for bleaching oils.  In an example, an unbleached hydrocarbon oil, namely a semi-finished solvent refined dewaxed mineral oil with viscosity corresponding to SAE No. 30 and a viscosity index of 90, was mixed with the clay and heated to 143 DEG C. in 15 minutes in a carbon dioxide atmosphere, after which the mixture was cooled to 100 DEG C. and filtered.

Abstract: 604,952. Sliding shelves. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 10, 1945, No. 33346. Convention date, Dec. 13, 1944. [Class 52(i)] A sliding shelf, for a refrigerator cabinet, comprises a channel section frame 10, with wires 12 to form a grill, supported cantilever fashion on pairs of rollers 13 on the side walls of the cabinet near the front, while the rear edge of the shelf is provided with pivoted arms 17 which have hard rubber stops 14 attached thereto and are fitted with guide members 15 so that when the shelf is pushed into the cabinet the members 15 strike the rear wall and cause the arms 17 to turn about pivots 19 to the position shown in Fig. 5. The arms are latched in this position preventing removal of the shelf. The arms 17 are forked at their pivoted ends and the lower prongs have elongated apertures 23 through which the pivots 19 pass so that the arms may be depressed slightly at their front ends 18 by lugs 28 against springs 24. When the arms 17 are in position parallel to the rear edge of the shelf latching is provided by stop pieces 27 which are riveted to the upper flange of the frame 10 and the shelf is prevented from being fully drawn out of the cabinet by the end pieces 18 of arms 17 becoming wedged against the rear rollers 13 and the frame 10. To withdraw the shelf from the cabinet the arms 17 are disengaged from the locked position by depressing the lugs 28. To assist in guiding the shelf during movement, guide pieces 16 are .attached to the ends of the roller shafts.

Abstract: 975,470. Couplings. COMMUNICATIONS PATENTS Ltd. Oct. 11, 1963 [Aug. 20, 1962], No. 33386/62. Heading H2E. Where a screened cable having a closely-fitting outer covering of resilient material is opened up to enable branch connections to be made, continuity of the screening of the cable sections each side of the branch is maintained by a resilient conductive strip, the ends of which are inserted between the screening and resilient outer covering of the two sections. As shown, the resilient conductive strip 15 is of beryllium copper formed into a step at each end, the intermediate portions 17 limiting the extent to which the end portions 16 can penetrate between the screening 7 and outer covering 5, and the linking portion 15 being longer than the distance between the outer coverings of the cable sections thus urging intermediate portions 17 against the edges of the outer covering. End portions 16 of the strip may be curved across their width so that the edges " bite " into screening 7 and their ends may be tapered. To minimize corrosion effects the conductive strip may be plated with tin or cadmium, covered by a sleeve of polythene or polyvinyl chloride between portions 16 and arranged together with the ends of the cable sections within a protective housing 18. A metal clip 19 may be applied around the connections.

Filed: 1928-11-16
Abstract: 300,652. Cincinnati Milling Machine Co., (Assignees of Ernst, H., and Nenninger, L. F.). Nov. 17, 1927, [Convention date]. Hydraulic transmission of power.-In hydraulic apparatus for feeding a tool or work carrier, a hydraulic cylinder is connected through a distributing valve V, Fig. 1, with the suction and outlet pipes 0, I of a pump M passing liquid at a predetermined uniform rate. To the pipe I is also connected a pump B delivering a small output at high pressure, the maximum pressure being determined by a relief valve E. By means of pipes 2, 7, the pressure in the pipes I, 0, act on the end of a spring-controlled valve F and on a piston carried thereby, so that the tapered end of the valve controls the quantity of liquid passing from the pipe 2 through a pipe 6 to a reservoir R. In a modification, a balanced valve 26, Fig. 4, is employed, its controlling spring 29 being adjustable. The hydraulic circuit may be modified by substituting for the pump M a throttle valve M', Fig. 5, in a pipe leading to the reservoir R.
