Title: Improvements in the production of solvent-stable alpha- and gamma-forms of metal-free phthalocyanine
IPC: C09B67/00
Filed: 1955-02-24
Abstract: Solvent-stable forms of metal-free a - and g -phthalocyanines are made by producing mixtures, on the one hand, of 2-30 molecules of the crude b -form or solvent-unstable a - and g -forms of the metal-free phthalocyanine or metal phthalocyanines which are converted into the metal-free phthalocyanines by mineral acids (e.g. sodium, potassium, beryllium, magnesium, calcium, strontium, barium, cadmium, mercury, or lead), and on the other hand, one molecule of a metal-free phthalocyanine which is substituted 1-4 times by halogen atoms or nitro groups, or of a correspondingly substituted aluminium, chromium, manganese, iron, cobalt, nickel, copper, or zinc phthalocyanine, and converting said mixtures into solvent-stable forms of metal-free a -and g -phthalocyanines by acid-pasting with 50-100 per cent sulphuric acid, the concentration being so chosen that the b -form of the metal-free phthalocyanine is in any case converted to a  or g , and the a  or g  is, if desired, converted to g  or a  respectively, and bringing said mixtures into a state of fine dispersion simultaneously or subsequently.  The mixtures may be made either by direct admixture or by partial substitution, e.g. partial halogenation.  Examples describe: (1) the partial chlorination of the a -form of metal-free phthalocyanine with chlorine in trichlorbenzene or phthalic anhydride, or with phosphorus pentachloride and acid-pasting of the mixture with 62 per cent sulphuric acid; (2) the acid-pasting of a , b -, or g -metal free phthalocyanine in 62 per cent, or 75-100 per cent sulphuric acid or in the monohydrate together with (a) a chlorinated metal-free phthalocyanine containing 19.6 per cent chlorine, (b) copper mono-, di-, tri-, or tetra-3(or 4)-chlorphthalocyanine, (c) copper (or aluminium, chromium, manganese, cobalt, nickel, iron, or zinc) 4,41,411,4111-tetra-nitrocopper phthalocyanine, (d) cobalt (or aluminium, chromium, manganese iron, nickel or zinc) 4,41,411,4111-tetrachlor phthalocyanine. Also in examples: (3) copper (or aluminium, chromium, manganese, iron, cobalt, nickel or zinc)-4,41,411,411-tetrachlor- or tetranitro-phthalocyanine is acid-pasted in concentrated sulphuric acid with calcium phthalocyanine in hydrochloric acid or in 62 per cent sulphuric acid or concentrated sulphuric acid with disodium, calcium, magnesium, beryllium, cadmium, mercury, or lead phthalocyanines.

Title: Improvements in and relating to undercarriages for aircraft
IPC: B64C25/62
Filed: 1936-02-25
Abstract: 470,928. Aircraft alighting - gear. BRIE, R. A. C. Feb. 25, 1936, No. 5631. [Class 4] Aircraft alighting-gear comprises an extensible and compressible shock-absorbing undercarriage and a pilot-operated locking-device for positively locking together relatively movable members so as to prevent the undercarriage from developing maximum extension. In one form, a member 11 carrying a wheel 14 and a member 13 slide within a casing 12 against the action of shock-absorbing means. When the members are compressed, operation of a hand-lever 26 through a Bowden wire 28, lever 25, links 23, 24 and levers 21, 22 cause pins 17, 18 to enter recesses 15, 16 to lock the strut in its compressed position. A spring 29 assists the engagement of the pins in the recesses. In a modification, the pin 17 is adapted to engage in the recess 15 before the pin 18 engages the recess 16, by this means the strut may have three lengths and the hand lever is consequently adapted to be locked in one or other of its corresponding positions.

Title: Improvements in carrier wave transmission systems
IPC: H04B3/11
Filed: 1922-02-27
Abstract: 197.758. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 27, 1922. Wired wireless systems.- In a carrier-wave system, the transmission efficiency is automatically kept constant in spite of varying conditions of leakage. Telephone. current from line 7, Fig. 1, and a carrier current from a harmonic generator 11 at station A are supplied to a modulator 10 which sends modulated current to the line 1 through the balanced transformer 20. At the same time the fundamental frequency of the harmonic producer 11 is sent out through the filter 22, amplifier 23, and filter 24. At the station B, Fig. 2, the fundamental frequency is separated by a filter 26 and fed tc a harmonic producer 27 which supplies demodulatory currents to the device 31 which is also fed with the modulated current through the filter 30. The output current of the demodulator 31 is fed to the line 36. Fig. 3 shows the relation between, the unmodulated currents supplied to modulators and demodulators and their output current. The amplifier 23 at station A is so arranged that the amplitude of the fundamental frequency is such that under normal conditions the unmodulated current derived from it has an amplitude OD, which is greater than that required to produce a maximum output current from the demodulator 31. If, owing to line conditions, the fundamental becomes attenuated so that its amplitude is (say) OC, the output of the demodulator tends to rise to the value CG but owing to the attenuation suffered also by the modulated wave the actual output is CF which is equal to DE. In transmitting from station B, if the, fundamental has become attenuated, the output of the modulator 38 is increased to CG which is a value such that owing to attenuation the output of demodulator 16 at station A will be CF. Only one channel is shown but a number of messages are sent simultaneously over the line 1 by a modulator and demodulator at each station associated with each harmonic generated by the device. 11. In the application of the invention to a system wherein an unmodulated wave is sent along with one or both side bands, the amplitude of each unmodulated wave is controlled instead of that of a fundamental wave. The line 1 is also used for low frequency telegraphy coming in from line 2 including the usual composite set 3.

Abstract: 393,606. Moulding reinforced concrete. FREYSSINET, E., 32, Rue St-James, Neuilly-sur-Seine, France. Nov. 26, 1931, No. 5898/33. Convention date, Nov. 27, 1930. [Class 87 (ii).] Relates to the processes described in Specifications 338,864, 338,934, [buth in Class 87 (iii), Moulding plastic &c. substances], 364,621, and 393,576, and consists in that the tension of some of the reinforcing members is utilized to cause deformation of the concrete whereby tension is induced in certain other of the reinforcing members. As applied to railway sleepers, precast end blocks 9, Fig. 1a, with embedded longitudinal reinforcements 6 are forced apart by rods 10 to tension the longitudinal reinforcements. Transverse reinforcement 8 is applied and the remainder of the sleeper cast. On setting of the concrete and removal of the rods 10 longitudinal contraction of the block results in its lateral expansion and consequent tensioning of the transverse reinforcements. Several sleepers may be cast simultaneously, the rods 10 of adjacent sleepers being linked in chain fashion, the longitudinal reinforcements of the several sleepers being tensioned by a single hydraulic jack &c. Hollow articles may have internal and external rubber bags to receive water under pressure whereby the walls of the article are compressed to induce the required stresses in the circumferential reinforcement embedded in the wall of the article. A press frame for a hydraulic jack may comprise pre-cast end blocks 21, 22, Fig. 3a, with longitudinal reinforcements 23a which are tensioned by the jack 26, transverse reinforcements 24 being mounted in the thrust areas of the blocks 21, 22 to minimize local deformations. Spiral reinforcements 25 are applied and the tie members 23 cast. After setting of the concrete the hydraulic pressure is released, whereby the tension of the members 23a tends to shorten the ties 23 and to expand them laterally, thus inducing tension in the spiral reinforcements 25. Specification 366,544 also is referred to.

Title: Improvements relating to thermal control devices for electrical apparatus

Filed: 1938-02-28
Abstract: 511,977. Thermal switches and protective systems. MICRO SWITCH CORPORATION. Feb. 28, 1938, No. 6311. Convention date, Feb. 27, 1937. [Class 38 (v)] A thermal switch has two bimetallic strips one operated by the temperature of an electric device and the other by heat due directly to the current flowing. In Fig. 3, two bimetallic strips 6 and 7 are both fixed at one end in an insulating support 8 on a base plate 13 covered with heat insulating material 15 which is fixed to a motor or other device. Contact 29 which moves between a fixed contact 26 and a stop 22 is carried at the junction of two bowed compression members 28 which rest at one end in a notch 31 in an insulating block 16 carried by a bent-over end of the bimetallic strip 6, with a tension member 27 held at one end by an upturned lug 21 on bimetallic strip 7. The load current passes from terminal 23 through the two legs of element 6, the closed contacts 26 and 29, the tension member 27 and element 7 to a terminal lug 24. The heated motor cooling air passes over the switch to cause element 7 to bend down until the switch opens with a snap action in the manner described in Specification 419,917, the materials and dimensions of element 6 being such that it bends but little due to changes in air temperature, but with a heavy overload, bending of strip 6 operates the switch, the resistance of element 7 being small so that little heating by the current occurs in it. Modifications are described wherein a pressbutton with optional 'latching needs to be operated before the switch recloses with decrease in temperature, or in which the bimetallic element has four legs, two possible seriesparallel arrangements of which make the switch suitable for use with two values of normal current, or in which the current flows not through the elements but through a separate heater. In Fig. 12 two switches are shown connected in two phases to protect a three-phase motor, the main current flowing through strips 6a and 6b only, while the current passing through the elements 7a and 7b and the switch contacts 29a and 29b energises the trip coil 50 of a circuit-breaker 51. The Specification as open to inspection under Sect. 91 also describes a switch which as shown in Fig. 16 (Cancelled) has a similar snap-action mechanism; the two bimetallic strips 60 and 61 are in contact and tend to bend in opposite directions, the switch opens due to the predominant effect of element 60 when the surrounding temperature changes, or due to a sudden rise in the current passing through the heater 62, the heat from which affects only the strip 60. No current passes through either bimetallic element. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 481,982.
