Each anchor comprises a member 25 with internally threaded sockets 28 at each end and a central transverse bore 29 through which cross members 26, 27 are secured, the member 27 having an internal threaded bore 36 and the member 26 having an internal threaded socket 34 and a threaded shank 32 engaging part of the bore 36. The head 33 of member 26 and members 25, 27 fit in the bores 21 and the head 33 and member 27 seat in recesses 30 at the ends of the bore 29. Driver slots are provided in the members 25, 26, 27 for manipulation by a screw driver. The connecting device 12 comprises a stud portion 40 secured to the anchor by a threaded shank 44 fitting 'in any of the threaded parts 28, 34, 36, the main part of the stud comprising a cylindrical body 42 with reduced end 43 leading to the shank 44, the end 43 seating in the bores 21. At the opposite end, a reduced neck 47 leads to a head 48 tapered at 45. A spring 41 is secured by a base portion 50 below each slot 18 so that a bowed portion 51 and free end portion 52 extend over the slot. A keyhole slot 53 therein, to fit the neck 47, has an enlarged lower end through which the head 48 can be passed, the panel 10 then being lowered so that the stud 40 is engaged by the spring 41 which is held under tension by the head 48, the rib 19 engaging the channel 20. Specification 784,299 is referred to.

Title: Thermoluminescence dosimeter system
IPC: G01T1/115
Filed: 1972-02-21
Abstract: 1342851 Thermoluminescence UNITED STATES ATOMIC ENERGY COMMISSION 21 Feb 1972 [16 March 1971] 7900/72 Heading C4S [Also in Divisions G1 and H5]  A thermoluminescence dosimeter is contained in a badge provided with an "open" window and filters such that different areas of the dosimeter are exposed to different radiation exposures from the radiation field under test, and is read out by heating at least one portion within each area and monitoring the resultant thermoluminescence.  The dosimeter 12 of Fig. 1 may, for example, be a matrix of polytetrafluoroethylene having LiF phosphor dispersed throughout to constitute 30% by weight of the dosimeter. The filter/ window areas shown 28-34<SP>1</SP> are suitably an open window, an aluminium filter (to pass all γ- and stop #-radiation), two filters of tin (300 mg./cm.<SP>2</SP> to filter out γ-rays below 25 KeV and at 1000 mg./cm.<SP>2</SP> to filter out γ's below 50 KeV) and a cadmium filter (responding to thermal neutrons). In the readout apparatus, dosimeters from magazine 12 are carried in window 50 in slide 52 to window 68. The slide is stepped along and at each dwell period, heater 62 is lowered to contact a thin strip like portion of the dosimeter, thermoluminescence being sensed by photomultiplier 66, whose output is fed via 72, 76 to recorder 82, e.g. a card punch or magnetic tape writer. Identification information is read from the dosimeter at 78. A modified heater and detector arrangement, Fig. 3, includes a quartz rod 92 through which hot gas, e.g. nitrogen is passed, the photomultiplier 94 being mounted above the rod. Roller 96 may also be heated, e.g. by electric means. Dosimeter modifications include: use of triangular filter areas; dosimeters of rod or bar instead of sheet form, the readout apparatus being appropriately modified. A plurality of heater-detector combinations may be used to read out a plurality of areas simultaneously. Li 2 B 4 O 7  : Mn; CaF 2  : Mn 2  ; CaF 2  : natural and CaSO 4  Mn are also mentioned and thickness and concentrations.

One end of the dryer projects into a hood provided with a hot water radiator 18 fed from a boiler 19, and a blower 20 is provided for directing warm air through the dryer. A similar blower 22 is provided to supply cold air to the lower chamber 10. The wet grain is supplied from a hopper 24<1>, Fig. 4, to an intermittent feed paddle 24 which delivers it to a conveyor 25. The paddle is driven by a rotating crank 26 through a rod 27 pivoted on a member 28, which is adjustable on a rod 29 carrying a pawl 30 which actuates a ratchet wheel 31. The conveyor 25 delivers to a box disposed above the inlet 7 and rocked to and fro by mechanism driven by the rocking of chamber 6.

Title: Process of making solid fuel briquettes
IPC: C10L5/22
Filed: 1940-05-07
Abstract: 550,167. Agglomerating fueL ERICKSON, J. A. May 7, 1940, No. 8221. Convention date, May 8, 1939. [Class 50] Solid fuel briquettes having a starch binder are made waterproof by mixing the briquette mixture, for example by spraying, with minute particles of a combustible material solid at ordinary temperatures but fusible at temperatures below the burning temperature of the fuel, forming briquettes and heating to above the fusing point of the material. Heavy hydrocarbons such as paraffin wax or asphalt are suitable for use. The briquettes are made with a starch binder which, before being added to this fuel, is mixed with water and a caustic such as sodium hydroxide or carbonate, the amount of caustic being about 2 per cent by volume of the starch. The mixture is agitated and heated up to 200‹ F. for about 30 minutes. The fuel may consist of anthracite fines, or of coke breeze and petroleum coke fines to which a low volatile strongly coking coal is added. In the case of lignites or bituminous coal an additional binder such as cement, tar, resin, or asphalt may be added. The materials are preferably heated during mixing to expedite the subsequent drying. An antiseptic such as copper sulphate or sodium fluoride may be added to prevent mould forming when stored in a damp atmosphere.

Abstract: 1461803 Textile treating compositions G BARKER 22 Feb 1974 [23 Feb 1973] 8228/74 Headings C3F and C3P [Also in Divisions A5 and D1] A low-density shaped body for treating textile fabrics to impart desired properties thereto, e.g. in a laundry tumbler dryer, is formed of a composition comprising a minor proportion of a water soluble or dispersable material and a textile adjuvant, the body being disintegrable upon the application of heat and moisture to release the adjuvant on to the fabric and to leave substantially no residue of the binder material. The body may be shaped, e.g. by moulding or extrusion, or may be a foam. The binder may be a high viscosity plastic material whose solubility is directly or inversely proportional to heat, and may dissolve or adhere to the adjuvant. The binder may be selected from polyvinyl alcohol, carbohydrate gums, e.g. ethylhydroxyethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose or methyl cellulose, natural plant and animal starches, and protein gums, and may account for 0À5-20% by weight of the solids. The adjuvant may be a softening or antistatic agent, e.g. distearyl dimethyl ammonium chloride, a non-ionic surface active agent, or a reaction product of a fatty acid (17-21 C) and hydroxyethylene diamine; an optical brightener; a germicidal agent, e.g. diisobutyl cresoxyethoxyethyl dimethyl benzyl ammonium chloride, cetyl trimethyl ammonium chloride or lauryl colamino methylformyl pyridinium chloride; or a fragrance imparting agent, and may account for from 5-99À5% by weight of the solids. Other additives which may be present include ammonium phosphate, urea, propylene glycol and polypropylene glycol. The compositions may be prepared by adding the powdered adjuvant to a dilute (1-20%) solution or dispersion of the binder material and either whipping to a stiff foam of bubble size 5-50 microns and density 0À2-0À8 g./c.c., or by blending to a uniform dispersion which can be cast, moulded or extruded, followed by drying the foam or dispersion to the desired configuration of low-density body. Preferably the material has a Brookfield viscosity of over 1000.

Filed: 1921-03-16
Abstract: 181,140. Carpmael, W. P., (Bagley & Sewall Co.). March 16, 1921. Fourdrinier paper-machines. - In delivering pulp to the wire cloth of paper machines running at high speeds, the pulp is so supplied that a pool is formed above the wire after passing the slice, through which pool the pulp flows, with agitation and intermingling of the fibres, at a speed approximately equal to that of the wire. The pool is maintained by a head of pulp in the flow box 7, in which the quantity of water is adjusted to the thickness of the paper to be made. A resistance surface over which the pulp flows may comprise an apron 11, or it may consist of a board arranged forward of the breast roll 1 and beneath the wire; or the slice 9 may be arranged in the rear of the centre of the breast roll, and the surface of the breast roll used for this purpose. Where a large quantity of water is used, the wire cloth may be arranged to run uphill from the breast roll, to give the water more opportunity to drain from the stock.
