Title: Polyamideimide compositions
IPC: C08G73/14
Filed: 1971-04-19
Abstract: 1309501 Polyamide-imide films TORAY INDUSTRIES 19 April 1971 [3 Feb 1970(2)] 21517/71 Heading B5B [Also in Division C3] A film-forming composition comprises (a) a polyamide-imide having a repeating unit of the general formula (II) (b) an organic solvent therefor; and (c) a phosphorus compound providing 0À00015 to 6À5% P by weight of the polymer. In the formulµ R 1 , R 3  and R 5  represent divalent organic groups, R 3  differing from R 5  and R 2  and R 4  are respectively tri- and tetra-valent organic groups having one and two pairs of carbonyl groups in cylic anhydride-forming positions. The polymers (a) preferably have an inherent viscosity above 0À4 and may be prepared by first reacting the appropriate tri- or tetra-carbonyl compound with an amino-acid H 2 N-R 1 -COOH or diamine H 2 N-R 5 -NH 2  in proportions giving a COOH terminated product which is then reacted with a diisocyanate OCN-R 3 -NCO. A large number of polymer-forming reactants, solvents and phosphorus compounds, both organic and inorganic, are specified. Making films.-The compositions are used to make films by being extruded or poured on to a plate, belt or drum and dried thereon. The phosphorous compound is stated to reduce adhesion thus enabling this technique to be used with these normally lightly adhesive polymers. The polymer in the film-forming composition may be incompletely imidized, depending on the temperature of formation of the carboxyl-terminated intermediate, imidization being completed after separation of the polymer. Examples illustrate film formation on various metal plates, belts or drums, e.g. of steel, stainless steel or chromium. Subsequent heat treatment, e.g. at 300‹ C. for 30 mins. may be effected to improve heat resistance, chemical resistance and electrical insulating properties of the film.

Title: Improvements in or relating to manure
IPC: C05F3/00
Filed: 1931-08-04
Abstract: 387,694. Drying poultry manure ; poultry-houses. YOUNG, R. A. G., Castlegate Mills, Malton, Yorkshire. Aug. 4, 1931, No. 22072 and 22134. [Classes 5 (ii) and 111.] Manure is made by drying poultry droppings by exposure to a current of heated air or other gas, preferably at a temperature of from 60-300‹ C., and subsequently directly grinding the dried droppings. The droppings may be collected on boards or trays, which may be sprinkled with a powdered drying material such as gypsum to prevent aggregation of the droppings, and transferred to the drying-apparatus. The process may be carried out in the apparatus shown in Fig. 4, wherein a hopper 13 feeds the droppings on to an endless band conveyer 14, conveniently of gauze, which conveys them in counter current to a current of hot air from a fan 16 and furnace 17 ; the dried material is then carried by an enclosed conveyer 18 to a grinder 19, from which the ground material falls into a container 20. Two sieve-like members may be mounted slightly resiliently between the hopper 13 and the conveyer in order that the droppings may be somewhat crumbled. The endless band conveyer may be replaced by a worm conveyer or by a rotary drum. The droppings may also be dried on wire mesh shelves 1, Fig. 1, in a drying cabinet 2 having a stove 5 underneath it to supply hot air. Alternatively, the droppings may be collected in the poultry house on trays T having legs 9 in the form of a hollow frustum of a cone and having a runner, e.g. in the form of a wheel or ball 9<1> at the bottom which may run on rails beneath the roosts. A number of trays may be coupled together. The trays are removed and a number stacked as shown in Fig. 2, the upper ends of the sockets of the legs 9 receiving the lower ends of the legs of another tray. The two ends 71, 7<11> of the trays are hinged so that they may be swung down; with this arrangement the opposite ends of adjacent trays may be swung down so that when the battery of trays is slid into the drying cabinet the cabinet is divided into two by baffles 11, the ends 7, 7<11> and the bottoms 8 of the trays. These tray bottoms may be of gauze. The cabinet is provided with hot-air inlets in the form of perforated pipes 10 and similar air outlets 10<1>.

Title: Improvements in or relating to the production of titanium oxide pigments
IPC: C10G71/00
Filed: 1932-08-08
Abstract: A dilute aqueous suspension of calcined titanium oxide is deflocculated by addition of an alkaline reagent to give a pH value of at least 7.2 and preferably 8--10, and the resulting suspension then subjected to elutriation to eliminate undesirably large particles.  Suitable deflocculators are alkali metal or ammonium hydroxides or carbonates, sodium silicate, and trialkali phosphate. Elutriation is effected at ordinary or elevated temperature by causing the suspension to flow upwardly at a speed of from 2 cm. to 0.3 c.m. per minute, particles of a size from 15 microns upwards to 6 microns upwards respectively then forming a sediment, and the smaller particles being entrained by the liquid. Alternatively elutriation may be performed in stages at decreasing speeds of flow to separate particles of successively decreasing size.  Settling of the elutriated suspension may be promoted by acidifying to a value below pH 6.5, say to pH 4.  The sediment obtained by elutriation is preferably reground in a pebble mill and again subjected to deflocculation and elutriation, whilst the settled suspension of fine particles is filtered, pressed, washed, dried, and crushed to form a pigment.  The process may be applied to composite pigments containing for example sulphate extenders or zinc oxide.

Abstract: 947,265. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. June 8, 1962 [June 9, 1961], No. 22308/62. Heading H4D. An electric circuit for measuring the time interval between the occurrence of incoming signals and reference pulses comprises a source of sine wave signals, means 2 to convert them to pulse signals, counters 3, 4, 5 having successively numbered outputs and coupled in cascade to the pulse signals to produce a reference pulse for each cycle of the last counter, means, including a respective switch 6, 7 or 8 associated with each counter and bi-stable multivibrators 14, 23 coupled to the switches ganged as shown, to select coincidence between a combination of the numbered outputs, a resolver 27 coupled to the sine wave signals, a pulse former 30 coupled to the resolver output, a bi-stable multivibrator 31 to deliver a " measuring " pulse on coincidence between the outputs of pulse former 30 and the selected combination of the numbered outputs, means 33 to apply a correction signal depending on a time difference between the measuring pulses and the incoming pulses to a motor 11 driving both the resolver 27 and the switches 6, 7, 8 whereby that time difference is reduced to zero, and a counter 32 coupled to motor 11. The invention is described as applied to the receiver in a " Loran C " system. 10 kc/s. sinusoidal signals are translated into 10 kc/s. pulses by unit 2 coupled to a first beam switching tube counting decade 3, the tenth output from which is fed to a second decade 4 and similarly for decade 5. The output of decade 5 is at 10 kc/s. which is also the master trigger for the Loran receiver. The numbered outputs of the counting decades are fed to correspondingly number inputs of rotary switches, each switch having segment lengths of about 27 degrees and two wipers spaced 18 degrees apart. Servomotor 11 drives the wipers of switch 6 directly and the wipers of switches 7 and 8 via successive 10 : 1 step-down gears. The wipers are connected as shown to delay-producing multivibrators 17, 22, 26 and to bi-stable multivibrators 14, 23. The output of bi-stable multivibrator 31 is thus a slave trigger pulse of the same repetition frequency as the master trigger output of decade 5 and delayed with respect to the master trigger by the " coarse ' amount introduced by the rotary switches and associated multivibrators and delayed a " fine " amount by the output of resolver 27. The total time delay is indicated on counters 32.
