Title: Improved apparatus for assisting or facilitating the landing and the take-off of aircraft on and from comparatively narrow strips
IPC: B64C9/38
Filed: 1953-07-17
Abstract: 764,684. Aircraft launching and alighting. GOETA, G. July 17, 1953 [July 22, 1952], No. 19899/53. Class 4. Apparatus for facilitating the landing or take-off of aircraft on narrow strips in winds having a severe side component comprises means on the aircraft for producing an air stream having a transverse component developing a force on the aircraft at or near its centre of pressure opposite to that produced by the side wind component. In Fig. 11 is shown an aircraft fitted with two turbojets 2, 3 rotatable about vertical axes and having their intensities variable by transmissions 4 of known type from the pilot's cabin. The turbojets may be retractable and disposed on the wings, empennage, or undercarriage. For take-off, the pilot rotates the turbojets to face the wind, and controls their intensities in accordance with the indication of a transverse wind speed indicator. The two units are preferably independently controlled, and are situated symmetrically with respect to the lateral centre of pressure. The side force produced enables the aircraft to take off from a narrow strip with its longitudinal axis in the direction of motion. In very severe winds, the axis may be inclined into the wind. After take off, the turbojets are stopped, left to cool, and then retracted. The reverse applies for landing. The turbojets may also be rotated to act as boosters, or as braking jets. Only one engine may be used, preferably disposed near the centre of pressure. Other types of engine may be used, or the engine may be housed in the fuselage, and have exhaust conduits leading outside the aircraft and variable in direction. Other applications are to reduce sideslipping and to assist accurate launching of freight, to produce a couple to balance the yaw torque upon failure of one engine, and to facilitate manoeuvring on land, sea, or a flight deck.

Title: Process for producing on fibrous materials water-repellent dressings resistant to washing, and aqueous emulsions therefor
IPC: C09K23/00
Filed: 1950-08-10
Abstract: An aqueous emulsion suitable for preparing aqueous impregnation baths for producing water-repellent dressings on fibrous materials, contains (a) as a water-repellent substance an ester of a methylol-melamine in which at least one but not all the methylol groups are esterified with an aliphatic or cycloaliphatic carboxylic acid having more than 8 carbon atoms and in which the remaining methylol groups are at least partially etherified with a lower aliphatic alcohol, and (b) as an emulsifying agent a water-soluble protein, a water-soluble cellulose derivative, or a water-soluble polymerization product capable of forming highly viscous solutions. Emulsifying agents specified are polyvinyl alcohol, methyl cellulose, gelatine, the ammonium salt of a maleic anhydride-styrene copolymer and the ammonium salt of carboxy methyl cellulose.  Other emulsifying agents that may be used with those specified above are fatty alcohol sulphonates, naphthalene sulphonic acid-formaldehyde condensates (neutralized with caustic soda), sodium m -hepta-decyl-N-benzyl-benzimidazole disulphonate, 4-stearylaminobenzene-1-trimethylammonium methyl sulphate and the condensate of octadecyl- and cetyl-alcohols with ethylene oxide. The emulsions may also contain paraffin wax or a water-repellent natural or synthetic wax.  Stabilizers such as triethanolamine, morpholine or ammonia may be added.  To prepare the impregnation bath, the emulsions are diluted by warm water and an acid or potentially acid catalyst added or the catalyst may be dissolved in the water used for dilution.  Catalysts specified are ammonium thiocyanate, ammonium nitrate, zinc nitrate, zinc chloride, magnesium chloride, hydrochloric acid, phosphoric acid, boric acid, aluminium chloride and formic acid.  Mixtures of catalysts may also be used. Methylol-melamine esters derived from carboxylic acids such as pelargonic, lauric, myristic, palmitic, stearic, oleic and cerotic acids, fatty acid second runnings (i.e. a mixture of fatty acids containing more than 18 carbon atoms as obtained by the fractional distillation of oxidation products of paraffin wax) and colophony, may be made in a manner analogous to the esters described in Specification 611,012, e.g. by heating the carboxylic acids, if desired under reduced pressure, with a methylol-melamine containing 4-6 methyl groups of which 2-6 are etherified with a lower aliphatic alcohol such as methyl or butyl alcohol.  These methylol ethers can be obtained in known manner by reacting methylol-melamine with the lower alcohol in the presence of a mineral acid.  Examples 1 and 4 describe the preparation of the stearic acid ester and mixed ester (stearic acid and fatty acid second runnings) respectively of methylol-melamine methyl ether; example 5 describes the preparation of the condensation product of cresol, 2-naphthol-6-sulphonic acid, alkali sulphite and formaldehyde; and examples 1, 2, 4, 5, 6 and 7 describe the preparation of the emulsions.

Title: Charge coupled circuits
IPC: H01L21/00
Filed: 1972-01-05
Abstract: 1377123 Charge coupled devices RCA CORPORATION 5 Jan 1972 [14 Jan 1971] 20040/74 Divided out of 1377121 Heading H1K In a charge coupled device utilizing a two phase clock supply, asymmetrical potential wells are produced by utilizing electrode pairs connected to the same phase of the clock supply, one member of the pair being spaced further from the substrate than is the other. As shown, Fig. 2, alternate polyailicon electrodes 28-1, 2, 3, and Al electrodes 26-1, 2, 3 are provided on an N-type Si substrate the Al electrodes overlapping the edges of both adjacent polysilicon electrodes but being connected to only one of these. The polysilicon electrodes are arranged closer to the substrate than are the Al electrodes so that each connected pair of electrodes produces an asymmetrical potential well with the deepest part beneath the polysilicon electrode. Alternate electrode pairs are connected to the two outputs of a two-phase power supply by means of which charges stored beneath one polysilicon electrode are shifted to the next polysilicon electrode, the flow being unidirectional due to the asymmetry of the potential wells. In a modification, Fig. 4 (not shown), the structure is the same but instead of the two members of each electrode pair being directly connected a direct voltage offset is provided, for example by feeding from appropriate tapping points on a potential divider in the two phase power supply. This offset voltage enhances the asymmetry of the potential wells produced. Fabrication.-A thick SiO 2  layer is thermally grown on an N-type Si wafer, an aperture is etched to define the device charge transfer path and a thin oxide layer is formed on the exposed surface. A polysilicon layer is grown over the surface, e.g. by depositing Si at an elevated temperature or by depositing amorphous Si and heating to 900‹ C., holes are formed for chargesource and drain regions, B is diffused-in to form P+ type regions and a thin layer of SiO 2  is deposited over the surface. Selected regions of the top oxide and polysilicon layer are etched away to leave the polysilicon electrodes and a layer of SiO 2  is thermally grown or deposited. Windows are opened over the source and drain regions and at places where contact is to be made to the polysilicon. A layer of Al is deposited and etched to define electrodes, contacts and connection tracks. In a non self-aligned structure the P + regions are diffused before growing the polysilicon. The semi-conductor material may be Ge or GaAs and the substrate may be of P-type material. The metal electrodes may also be of Mo, Mo-Au, Pt-Ti-Au, W-Al, or Al-Si alloys. All the electrodes may be of Al the first electrodes being anodized to produce the required insulation. Si 3 N 4  may be used as a dielectric. The electrodes may be produced by using a scanning electron beam either directly or to expose a photoresist.

Title: Improvements in or relating to electric pulse generators employing semiconductors
Inventor: CATTERMOLE KENNETH WILLIAM
IPC: H03K3/282
Filed: 1953-06-20
Abstract: 726,496. Transistor pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. June 20, 1953, No. 20041/53. Class 40 (6). In a pulse generator, a regenerative feed-back is arranged between collector and, emitter so that there are two current conditions, at least one of which is unstable and the period during which the circuit is in the or one of the unstable conditions is determined by the periodic feature of the feed-back circuit. The feedback circuit may comprise either a series tuned circuit or a delay line short-circuited at its remote end, and the transistor has a current gain exceeding unity. After a pulse has been generated, the collector falls to a large negative potential which is fed over the series resonant circuit 10, 11, Fig. 1, to the emitter, thus blocking the transistor. The potential of the emitter rises as capacitor 11 is charged, the collector falling more slowly in potential, Fig. 2, since resistor 5 has many times the value of resistor 7. When the emitter rises to earth, the transistor conducts and collector current flows, the resulting rise in potential being fed back over circuit 10, 11 to the emitter. This cumulative action causes a sharp leading edge 14 to occur which is terminated when the collector approaches earth. The rise in the emitter potential is limited by the fall in emitter resistance but executes a half-sine wave 16 due to the resonant circuit 10, 11. When the emitter again falls below earth, the collector current ceases and the sharp trailing edge 17 occurs due to the feed-back over circuit 10, 11. The resonant circuit causes the emitter potential to overswing negatively, subsequently rising prior to the generation of the next pulse. Triggered pulse generator and frequency dividing circuit. In a modification, Fig. 3, the emitter is caught at a potential slightly negative with respect to the base to prevent the continual generation of pulses by the use of a diode 27 biased slightly more negative than diode 26 by a potential divider 23, 24, 25. A negative triggering voltage is fed in over capacitor 31 to base resistor 22, a negative pulse then existing across this resistor whilst the transistor is conducting, Fig. 4. By employing a biased diode 32 only the upper part of the pulse on the collector is fed out. If a signal having a periodicity such that a small multiple n is slightly greater than t 1  - t 3  is applied to the input, pulses are fed out every nth period. A second stage may be fed from the base resistor of the first over an attenuating resistor, Fig. 5 (not shown), to give further subdivision. Modifications. The series resonant circuit 10, 11 may be replaced by a delay network short-circuited at the remote end, Fig. 6 (not shown). Triggering may be effected by a positive pulse applied to the emitter or pulses applied to both emitter and base.

Filed: 1959-06-13
Abstract: 958,211. Forming cartons. BOXFOLDIA Ltd. June 7, 1960 [June 13, 1959], No. 20297/59. Heading B5D. [Also in Division B8]. A machine for forming collapsed cartons from the blanks shown in Figs. 1, 2 and 3 and which are secured by adhesive comprises a pair of endless belts 33 for continuously advancing a succession of initially flat blanks along guide bars 35, fingers 38 which press down the laterally extending flaps and sides of each blank to ensure that a pair of divider elements 37 raise either the sides B and depress flaps F, G or raise the flaps and depress the sides depending on whether the flaps are secured to the inside or outside of the sides, wheels 45 or short belts which apply glue to the blanks, and means for folding over and pressing together the flaps and sides in the position shown at the left hand side of Figs. 1-3. The folding means for the blank shown in Fig. 1 comprises converging ends of the elements 37, bars 47 which engage the partially folded over flaps as they leave the elements 37 and complete the folding of the flaps as the blank continues to advance. The ends of bars 47 are extended as strips which retain the flaps while belts 49 fold over the sides on to the flaps, the belt being pressed down by roller 50 to ensure adhesion between the flaps and the side. The flat, folded blanks subsequently pass to a stacking mechanism. For folding the blank shown in Fig. 2, the machine is modified so that the fingers 38 press the sides B upwardly thereby ensuring that the sides engage the top surface of the elements 37 and the flaps F, G pass beneath the elements, and the subsequent folding means comprises bars 52 which fold up the sides and corner flap folding bars 53, the bar 47 being dispensed with. The machine is further modified for folding the blank shown in Fig. 3, see Fig. 16. The elements 37 have parallel edges 39 and tapered strips of timber 55 are secured to the underside of each element. A deflector finger 54 at each side of the machine ensures that portions F, G engage the upper surface of elements 37 and that portions F1, G1, and C are deflected beneath the elements. A holding down bar 47 retains the centre of the blank while endless belts fold the blank about lines E, H, and I. In the first and third forms of the machine the ends of elements 37 first engaged by the blanks' are bent down from the horizontal; in the second form the undersides of the members 37 are horizontal. The numerous parts of the machine are adjustable to accommodate blanks of different size.
