Abstract: 164,831. Sterling Telephone & Electric Co., Ltd., Bell, F. G., and Davey. W. C. March 12, 1920. Addition to 106,706. Order apparatus; systems of wiring indicators. -Comprises modifications of the system described in the parent Specification for exhibiting simultaneously at a plurality of receiving stations in a factory or the like a signal, such as a combination of coloured lamps, for summoning to the telephone or elsewhere a person to whom that combination is particular. According to the present invention, a single group of selecting relays, such as Rr, Rb, Rg, controls the lamps at several neighbouring stations. In order to prevent deterioration of the relay-contacts due to interruption of heavy lighting-currents, such currents are additionally broken at the operator's station bv a suitable switch. In the form shown in Fig. 1, the arm a of the operator's switch 5 closes the following circuits which are energized in parallel by the battery 6: (1) A circuit containing contacts 12 operated by a pendulum 13 and a winding 14 acting on the pendulum, which consequently closes intermittently the contacts 10; (2) a circuit containing the contacts 10 and a number of bells 23, one at each receiving station B; (3) a circuit containing one of the groups of selector-contacts (which are shown at 23 and are selectively operated by push-buttons), and the corresponding operative windings 1 of the relays Rr, Rb, Rg. The arms band c of the operator's switch 5 close a heavy-current circuit containing the hold-up windings 2 and contacts 4 of the selected relays, together with the corresponding selected lamps Lr, Lb, Lg, at the stations B. It follows that the lighting-current flowing through contacts 4 is not broken at the operator's switch 5. In a modification a single winding is substituted for the two windings 1 and 2 of each relay, the contacts 4 being arranged in parallel with the contacts 22.

Title: Method and apparatus for testing using ultrasonic pulse signals
IPC: G01N29/38
Filed: 1965-02-23
Abstract: 1,089,923. Ultrasonic testing apparatus. S. R. W. KAULE. Feb. 23, 1965 [Sept. 12, 1964], No. 7862/65. Heading H4D. In a flaw-detection system in which ultrasonic pulses are received after reflection from or transmission through the material under test, interference pulses originating from electric, magnetic or electromagnetic noise fields in the vicinity of the ultrasonic receiving system are suppressed by detecting the interference pulses separately from the ultrasonic pulses, amplifying the interference pulses and using them to render a section of the ultrasonic receiving system insensitive for the duration of the interference pulses. In the embodiment of Fig. 2, a receiving transducer 1, which may also be used as the transmitting transducer, feeds echo signals through an amplifier 4 to a cathode-ray tube display 5 and to one input b of a three-input anti-coincidence gate 9. Noise signals detected by a capacitive pick-up, inductive loop 6a or aerial 6 are fed through an amplifier 7, including a half-wave or full-wave (not shown) rectification stage, to a second input c of gate 9 and to a device 11 which indicates the average noise factor i.e. the total duration of the noise pulses per unit time. A gating pulse, of pre-set delay with respect to a transmitted ultrasonic pulse and of pre-set width, is produced by a generator 8 and applied to the third input a of the gate 9 so that those echo pulses occurring during the gating interval, i.e. echo pulses from objects within a selected partial range, appear at the output, d, of gate 9 in the absence of a signal at the input c. The output signal at d is applied to a stage 10 which may be of the type producing a " go-no go " signal when the amplitude of the gated echo signal exceeds a preset level. The aerial 6 may have directional characteristics to prevent low-level continuous interference, e.g. from a nearby radio transmitter, from permanently blocking gate 9. In a second embodiment (Fig. 1, not shown) the gating pulse generator 8, the gate 9 and the output stage 10 are omitted and the rectified output from the noise amplifier 7 is arranged to block the echo-pulse amplifier 4.

Patent GB-791854-A (GB)
Title: Chemical process and product
IPC: C08G18/52
Filed: 1955-03-18
Abstract: A polyurethane rubber is obtained by reacting a polyalkylene ether thioether of molecular weight at least 732, in which there are preferably from one to fifteen ether links per thioether link and in which the terminal groups are hydroxyl, with an excess of a diisocyanate, and reacting the intermediate with a chain extender, e.g. water, glycol, diamine, dicarboxylic acid or other compound having two groups containing hydrogen reactive with isocyanate groups, to give a product which can be cured by heat and pressure, if necessary after incorporating additional diisocyanate.  In a modification the polyether, diisocyanate and chain extender are reacted simultaneously.  The intermediate may be stablized by incorporating a nitrogen base as described in Specification 791,853, or by ensuring that no free isocyanate groups remain. With increased sulphur content the polymers tend to be more plastic, with decreased sulphur, more rubbery.  The alkylene groups in the polyether/thioether may contain up to 10 carbon atoms and need not all be the same.  Ten examples are given, using polyethers of various sulphur contents and a molar excess of diisocyanate from 7 to 1 to 1.7 to 1.  Water and tolylene diamine are used as chain-extending agents and pyridine as catalyst in the chain-extending reaction.  The additional diisocyanate used for curing, when necessary, was N,N1-bis-(3-isocynato-4-methyl-phenyl) urea.  Piperidine was used as stabilizer for certain intermediates.  The molecular weights of the polyethers ranged from 1500 to 5200.  Figures are given for various physical properties including water and liquid hydrocarbon absorption.  Certain of the polymers remained rubbery down to - 20 DEG  F.  The polyalkylene ether-thioether glycol starting compounds may be prepared by azeotropic distillation of water from a suitable glycol or glycol mixture using e.g. p-toluene sulphonic acid as catalyst or by reacting bis-halogenothioethers with alkali salts of glycols.  In examples: (1) thiodiglycol and paraformaldehyde were condensed to give a polyetherthioether of M.W. 1500; (2) thiodiglycol was self-condensed to a polymer of M.W. 3360; (3) thiodiglycol and ethylene glycol were condensed to a polymer of M.W. 5200; (4) thiodiglycol and diethylene glycol were condensed to a polymer of M.W. 3300; (5) thiodiglycol and triethylene glycol were condensed to a polymer of M.W. 3400; (6) thiodiglycol and 1.4 butane diol were condensed to a polymer of M.W. 2600; (7) as in (4) but yielding a polymer of M.W. 2490; (9) as in (6) but yielding a polymer of M.W. 1735.  In the condensation reactions toluene or benzene was present and the water removed azeotropically, the polymer finally being purified and dried.

Title: Process for the production of furfural
IPC: C07D307/50
Filed: 1956-03-14
Abstract: Furfural is manufactured by a process comprising treating calcium phosphate with hydrochloric acid to give a hydrolysing solution including monocalcium phosphate, adding the solution to a pentosan-containing material and separating furfural from the resultant mixture by extraction with steam under pressure.  The hydrochloric acid may be formed in the solution by using sodium chloride or potassium chloride with sulphuric acid.  Suitable pentosan-containing materials are, for example, dry maize cobs, rice husks, oat husks, olive husks, lavender straw and sunflower seed shells.  The residual acidic lignin after separation of furfural may be neutralized with ammonia to give ammonium phosphate and complex ammoniacal humates.  In an example, dry maize cobs are treated with a hydrolysing solution consisting of water, tricalcium phosphate and hydrochloric acid and steam is circulated under pressure through the mixture; the vapour coming from the hydrolysis is condensed and fractionated to give furfural.ALSO:Pentosan-containing materials, such as dry maize cobs, rice husks, oat husks, olive husks, lavender straw and sunflower seed shells are treated with a hydrolysing solution obtained by treating tricalcium phosphate with hydrochloric acid and the residual lignin, after the removal of furfural by steam distillation, may be used as a fertilizer.  This lignin is acid but may be neutralized with ammonia to give a humic fertilizer containing ammonium phosphate and complex ammoniacal humates.
