Abstract: 607,350. Uncoiling strip from reels. TRIGGS, W. W. (Bliss Co., E. W.). April 25, 1944, No. 26879/46. Divided out of 607,276. [Class 83 (iv)] Altering molecular structure; metal - sheet feeds.-Metal strip feeding means, e.g. for a stamping-machine, employs two coil cradles designed to permit a coil to be received without shock, and comprising carrying members supporting pairs of roller-carrying shafts and mounted for rocking movement about the driving shafts for the rollers by means of supporting tubes receiving the driving shafts over part of their length. The strip is fed alternately from the coils on the two cradles, the coil on one cradle being renewed during feeding from the other. The strip passes round and between a series of flexing rolls to break up the grain and finally passes to the machine through feed and straightening rolls, as described in Specification 607,276. When a new coil is to be introduced, fluid pressure is admitted to a cylinder 101, Fig. 3, to raise a piston with a head 107 concave to suit the coil. This raises rocking members 111 with flanges 114, 115, engaging recesses in the head 107 and side frame 106. Supporting rollers 95 for the coil are mounted in frames 96, rocking about supporting tubes 81a that enclose driving- shafts 80 and are supported in pedestals 89. The members 111 have elongated holes to pass the tubes 81a. As the coil rolls over the members 111, the frames 88, 96 rock to provide a level passage to the heads 107 where the coil is retained by the concavity. The piston is then lowered and the coil comes to rest on the rollers 95, the members 111 being now clear of the head 107 and resting clear of the coil on the roller axles 94. End discs 70 for the coils are adjusted to the width thereof by a pinion 76, on a motordriven shaft, driving a cross-shaft 79a chain geared at 74 to nuts on screws 71 attached to the discs. A clutch 77 permits individual adjustment of one disc. The rollers 95 are driven through gears 93 from pinions 92 on the shafts 80, geared at 81 to a pinion 82 driven by a hydraulic motor.

Filed: 1966-06-18
Abstract: 1,146,173. Triaryl phosphates. GEIGY (U.K.) Ltd. 19 June, 1967 [18 June, 1966], No. 27316/66. Heading C2C. [Also in Divisions C3 and C5] Triaryl phosphate esters or a mixture of such esters are produced by contacting phenol with an alkylating agent containing from two to sixteen carbon atoms per molecule, and contacting the alkylated phenol product with a phosphorylating agent to produce a triaryl phosphate or mixture thereof, the proportion of alkylating agent being within the range of from 5% to 65% by weight of the phenol. Suitable alkylating agents are alkyl halides, alkanols or olefins, preferably an olefin or a mixture or two or more thereof, and the reaction is conveniently catalysed by a Lewis or Bronsted acid. The alkylation is preferably carried out in the presence of gaseous hydrogen halide. The alkylated phenol product may be used as such for the phosphorylation reaction or may be purified. The phosphorylation may be carried out using the same catalyst as in the alkylation or a different catalyst may be used. The preferred phosphorylating agent is phosphorus oxychloride. The products are useful as additives for lubricants, fuels and hydraulic fluids and as plasticizers for synthetic polymers.
Patent GB-465521-A (GB)
Title: Improvements in or relating to the manufacture or treatment of textile materials
IPC: D06M15/39
Filed: 1935-10-03
Abstract: Crimped and curled artificial threads are coated with a readily-removable film-forming substance before subjecting to operations such as fabric formation in which they are subjected to tension.  As suitable film-forming substances are specified, rubber, waxes, stearic acid, and particularly polymerized unsaturated organic compounds, e.g., polymerized vinyl esters, polymerized vinylethers, and polymerized esters of acrylic or methacrylic acid, polybasic acid-polyhydric alcohol resins, cellulose esters or ethers, carbohydrates, especially celluloses, and albumens.  Particularly useful are film-forming substances which are insoluble in water but soluble in water containing small amounts of alkali, e.g. ammonia. The film-forming substance may be applied simultaneously with lubricants, softeners, soaps or higher fatty acids.  In an example, a voluminous cellulose acetate yarn is treated with a solution of polyvinyl acetate in methyl alcohol, hydro-extracted and dried.  The yarn is woven or knitted and the polyvinyl acetate then removed.  In a second example, a cellulose acetate yarn crimped by the process described in Specification 424,880, [Group IX], is treated similarly, using a solution of the polymerization product of the methyl ester of acrylic acid.  In a further example, the yarn consists of a crimped regenerated cellulose yarn and the film-forming substance an aqueous solution of saponified polyvinyl acetate.

Title: Echo sounding apparatus
IPC: H03G7/02
Filed: 1965-06-28
Abstract: 1,115,261. Echo-sounding; automatic gain control. ELECTROACUSTIC G.m.b.H. 28 June, 1965 [26 June, 1964], No. 27368/65. Headings H3Q and H4D. In an echo-sounding arrangement for distinguishably recording echo details on electrosensitive paper of limited tonal range, highfrequency amplitude variations in the envelope of the echo signal are emphasized by an amplifier provided with automatic gain control (AGC) and with a further gain control system which acts in opposition to the AGC and has a smaller time constant than the AGC system. In the embodiment of Fig. 2, a timer III, which may be coupled to a chart recorder VI, controls a pulse transmitter I and gates off a receiver pro-amplifier IV during the transmission of a pulse. Echo signals from amplifier IV undergo further amplification in stages RÍ1 to RÍ4. A proportion of the output of stage RÍ4 is rectified and smoothed in a network A, having a time constant T 1  = R 11 C 13 , to provide a negative AGO voltage U 4  which is superimposed on a pre-set bias voltage U 5  and applied to the grids of stages RO1, RÍ3. A proportion of the output of stage RÍ2 is rectified and smoothed in a network B, having a time constant T 2  = R 3 C 6 , to provide a positive gain-controlling grid bias for stage RÍ3. T 2  is made substantially smaller than T 1  so that rapid fluctuations in amplitude of the echo envelope, e.g. due to stratification of the sea-bed or to fish near the sea-bed, receive greater amplification than do slower fluctuations. The degree of emphasis given to the echo details may be varied by varying the grid biasing conditions of stages RÍ 2  and RÍ3. In the embodiment of Fig. 5, stages RÍ5 and RÍ6 replace the stages RÍ3 and RÍ4 of Fig. 2. The AGC voltage is developed by a network C and applied to the grids of both stages RÍ5, RÍ6. Network C and the grid circuit of stage RÍ5 have respective time constants R 16 C 15  (or R 18 C 16 ) and R 17 C 17  which introduce a delay in the application of the AGC voltage to stage RÍ5, thus giving emphasis to the echo details. A decaying negative pulse may also be applied to the grid of stage RÍ5, by way of a diode D6, to provide conventional swept gain for the echo signals to compensate for increased attenuation of the echo-sounding pulse with travel-time. The time constant of network C may be selected to suit operating parameters of the echo-sounder (e.g. vertical, oblique or horizontal sounding, and transmission pulse-length). A Zener diode Z may be incorporated in network C to prevent AGC action for weak echo signals. An operating threshold may also be assigned to both the AGC system and the further gain control system of the Fig. 2 embodiment.
