Title: Improvements in and relating to laminar suspension or shock-absorbing springs for use on vehicles and aircraft
IPC: B60G11/04
Filed: 1919-10-15
Abstract: 145,325. Owers, E., Pearson, F. C., and Bundt, A. W. Oct. 15, 1919. Laminar springs.-In a laminar suspension spring for use on vehicles and aircraft, the leaves at one end bear directly on each other, but are spaced apart at their other ends, and a bearing- plate, fastened upon the central portion of the spring, projects over the separated ends, so that it acts under the load to bring the ends to bear on each other successively. In the form shown in Fig. 1, the bearing plate E is secured to the spring at a, its free end bearing against a block c pivotally mounted on a bolt B on the chassis. The leaves of the spring are spaced apart by short packing-pieces which preferably taper towards their ends, being held in close relationship with the leaves by a clamp e secured to the bearing- plate E. A roller may be substituted for the block c, or the block and the bolt D may be exchanged, the free end of the bearing-plate being in that case formed with a rolled eye. In Fig. 3 the spring is reversed, the bearing plate E bears upon the axle, and one end of the spring is mounted on a bolt carried by swivelling links F pivotally mounted on the chassis.

Title: Improvements in or relating to nitrogen-containing thermosetting resins having aliphatic sulphate and sulphonate residues and to a process for preparing the same
IPC: C08G12/04
Filed: 1950-10-18
Abstract: Nitrogen - containing thermosetting resins containing aliphatic sulphonate or sulphate groupings are prepared by condensing in water 1 mol. of an amino compound, an aldehyde, .05- .5 mol. of a water soluble salt of a compound NH2 - R - X (where R = saturated alkylene of 1 - 5 carbon atoms and X = SO3H or SO4H).  Amino compounds which may be used are urea, thiourea, cyanamide, dicyandiamide, guanidine. Aldehydes mentioned are formaldehyde, its polymers, acetaldehyde, propionaldehyde, benzaldehyde and furfural.  Compounds of formula NH2 - R - X mentioned are taurine (2 - amino ethane sulphonic acid); amino ethane sulphuric acid; 1 - aminopropane - 2 sulphonic acid; 1 amino butane - 2 - sulphonic acid; b  - aminopropane - 2 - sulphonic acid and 1 - aminopropane - 2 - sulphuric acid.  Sodium, potassium and lithium salts are referred to.  Preferably methylol compounds are formed in alkaline solution, the sulphate or sulphonate is added, the solution concentrated (e.g. by flash concentration if desired at reduced pressure), acidified and heated.  The solution is finally stabilized by addition of alkali.  The products may be used for ion - exchange, treating textiles, or, especially, for addition to paper pulp, precipitation on the film with alum and curing in the formed paper (see Group VIII).  In the examples condensation products are prepared from 1 mol. urea, 2.7 mols. of formaldehyde at a pH of 7.5 - 8.0.  After some initial condensation 0.2 mols. of the sodium salt of either taurine or 2 - amino ethane sulphinic acid were added, and the mixture concentrated at reduced pressure.  The solution was then acidified and heated under reflux to a viscosity of 5 poises, neutralized and cooled.  The resin solution was then added to paper pulp and precipitated on the fibres with aluminium sulphate.

Patent GB-917453-A (GB)
Title: Improvements relating to synthetic textile fibres
IPC: D01D5/20
Filed: 1960-07-21
Abstract: The invention comprises highly oriented nodular fibres of a synthetic organic polymer of uniform chemical composition having an oriented surface and closely spaced intermittent regions of enlarged diameter, the ratio of the diameter of the enlarged regions to that of the remainder of the fibre being between 1,1 and 2,5 and the regions of enlarged diameter occurring along the thread line with a frequency of at least 10 per inch, particularly between 50 and 500 per inch.  Such fibres are produced by subjecting fibres of a synthetic organic orientable fibre-forming polymer to a first drawing step while the fibres are in contact with a surface-crack-promoting agent, in which step the fibres are crack-drawn to at least 1,01 and preferably from 1,01 to 2,5 times theeir undrawn length, but insufficiently to orient them completely, and then to a second drawing step carried out under conditions such that further crack-drawing is avoided, e.g. by removing the agent before the second step or by carrying out the latter at a temperature sufficiently high to plasticize the fibres. "Crack-drawing" is defined as drawing under conditions such that the small surface cracks produced on the fibre by the agent are considerably enlarged by sharp-neck drawing which is initiated at the surface cracks.  Crack-drawing is suitably carried out at room temperature.  The suitability of an agent for producing cracks may be determined by observing whether the placing of the fibre in the agent under slight tension causes cracks.  The agents are preferably liquids, but may be vapours. If liquids, they should not be solvents or string swelling agents for the polymer.  They preferably have a surface tension relative to air not greater than 60 dynes per cm. measured at the crack-drawing temperature and are preferably non-aqueous.  The fibre polymers may be polyamides, polyesters, polyurethanes, acrylic and vinyl polymers and polyhydrocarbons such as linear polypropylenes.  In examples, undrawn polyethylene terephthalate continuous filament yarn soaked in narrow boiling-range kerosene, undrawn polyhexamethylene adipamide monofil and poly(m-phenylene isophthalamide) yarn, both soaked in methyl isobutyl ketone, are treated to impart a nodular configuration to them. Acetone, dimethylformamide, dimethylsulphoxide, methyl ethyl ketone, and methylene chloride are other suitable cracking agents.  Ethanol and ethanol-water mixtures are suitable cracking agents for most polyesters and polyamides, but carbon tetrachloride and kerosene are unsuitable for polyamides.  Nodular fibres according to the invention have a delustered appearance.  Specification 905,833 is referred to.

Abstract: 682,760. Colour filters. THOROGOOD, J. E. Feb. 20, 1952 [Nov. 1, 1951], No. 25529/51. Class 97 (i). [Also in Groups XL (a) and XL (b]] A colour filter for viewing normal black- and - white television images has parallel bands, each adapted partially to absorb a different part of the visible spectrum, the outer bands A, B absorbing light of lower frequency than the intermediate bands C, D, and each band merging into the adjacent band or bands. The upper band A is in the blue-violet range and occupies one quarter of the filter height, the middle bands C, D are in the redorange range and occupy the centre half, whilst the lower band B is in the green range. The middle region is formed with two fairly intense bands C of red-orange and the remainder D of light flesh colour. The filter is stated to reproduce outdoor scenes in approximately true colour and to reduce glare in all cases. The filter may be made from non-inflammable photographic film or a plate which is first fully exposed and fixed, then sprayed with transparent dyes on the emulsion side, and finally washed, dried and polished. Alternatively the emulsion may be fixed after washing. Other transparent material such as glass, synthetic resin or the like may be employed to construct the filter. Analine dyes in a mixture of water and acetone are suggested. The filter may be fixed in front of the television cathode-ray tube or projection screen, or may form an integral part or the glass or like front of the cathode-ray tube. Reference has been directed by the Comptroller to Specification 695,001.

IPC: B64C29/00
Filed: 1966-06-10
Abstract: 1,131,093. V.T.O.L. aircraft. DORNIERWERKE G.m.b.H. 10 June, 1966 [18 June, 1965], No. 25956/66. Heading B7G. A control system for a V.T.O.L. aircraft having a jet propulsion engine with tiltable nozzles comprises a power output control and a thrust direction control therefor, coupled together in such a manner that, when the thrust direction control is operated, the power output is automatically adjusted to maintain the vertical component of thrust substantially constant. The system shown has two push rods 31, 32 each connected to the power output control devices of the engine. The rods 31, 32 are connected by linkage 43, 55, 56, 57, 58 to a power output control lever 18. A thrust direction control lever 2 is provided which acts through linkage 3-6 on a link 8 connected to devices for effecting tilting of the jet nozzles. When either the lever 2 or the lever 18 is moved, intermediate linkage 40, 11 ensures compensatory movement of both the rods 31, 32 and the link 8. If the lever 2 is moved in a direction which results in the nozzles moving from a vertical towards a horizontal position, a rod 10 is also moved whereby linkage 11 causes the rods 31, 32 to move in a direction to increase the power output. If the lever 18 is moved to increase the power output a rod 43<SP>1</SP> is also moved whereby the link 8 is moved in a direction tending to move the nozzles towards the horizontal by an amount dependent on the setting of a transmission 45 automatically set to ensure that the horizontal thrust component remains constant. The ratio of the transmission 45 is dependent on the position of a lever 53 influenced by the position of the thrust direction control lever 2. In a simplified system, Fig. 1 (not shown) adjustment of the engine power output does not affect the direction of the thrust. To simplify the operation of the system the two control levers may be combined into a single control member, Figs. 3 and 4 (not shown) so that rotation of the control member operates the power output control devices and axial movement of the control member operates the thrust direction control devices. Servo-motors may be incorporated in the system and the mechanical coupling between the controls may be replaced by an electrical or electrohydraulic coupling.

Title: Electronic store for the transmission of binary data

Filed: 1972-06-05
Abstract: 1390101 Data storage JEUMONT-SCHNEIDER 5 June 1972 [7 June 1971] 26148/72 Heading G4C A data store includes a chain of series connected shift registers R 1 -R n  for each bit E 1 -E y  of data to be stored and two auxiliary chains R 1 <SP>1</SP>-R n <SP>1</SP> and R 1 <SP>11</SP>-R n <SP>11</SP>, the first for generating a signal indicating saturation of the store and the second for generating marker bits to indicate the positions in which data is stored. The data output rate is adapted to the required read-out facility, the write-in rate being as required. Shifting is controlled by a clock (not shown). Read-in.-This occurs when a signal C 1  is in its "1" state. This results in the input data being inverted by NAND gates 3 and converted to their original state by NAND gate 2 (due to the "1" signal at input C to the gates 2 since a NAND gate 4 receives a "0" signal as a result of inverting the signal C 1 ), for entry into the first register R 1  of the chain. Simultaneously a "1" marker bit is entered in register R 1 <SP>11</SP> since the output of NAND gate 6 is held at "1" by the inverted C 1 . Read-out.-This occurs when the signal C 1  is in its "0" state, the registers being shifted by the clock until the marker bit output S y+2  changes to its "1" state at which time the oldest stored date is available at the outputs S 1 -S y  of the chains of registers, together with an overflow bit S y+1 . A signal C 2  is then switched from its "1" state to its "0" state as the read-out data is looped back to the store input. This results in a "0" bit being fed in to the registers R 1 <SP>1</SP> and R 1 <SP>11</SP> with consequential effective erasure of the data since the associated marker bits and overflow bits are forced to their "0" state. The signal C 2  then reverts to its "1" state so that subsequent data is fed back into the store without the marker bits being erased. Reading continues until the output S y+2  becomes "0" when the clock is stopped so that the store is restored to its state before the start of read-out. Overflow.-If the marker bit output S y+2  is in its "1" state when the signal C 1  is also in its "1" state (indicating that the store although full is in its "read-in" state), the input bit E y+1  is brought to its "1" state. This ensures that any subsequent data read-in after space has been made by reading out has a "1" bit in the corresponding position in the register chain R<SP>1</SP> so that when this data is read-out the resulting "1" signal at output S y+1  indicates that this data was read-in after the store was full and consequently that other data may have been lost.
