Abstract: 1413745 Gyrocompass TOKYO KEIKI K K 9 Feb 1973 [12 Feb 1972] 6623/73 Heading G1C [Also in Division G3] A control system operating on an object which is subjected to periodic motion includes electrical means including an amplifier which makes the system unresponsive to motion having a period much greater than the natural period of the object. As shown, the invention is applied to a gyrocompass. Blocks 21 and 22 represent the vertical and horizontal axes respectively of the gyro. An input torque at P1 produces an inclination e(S) at P2 and an input P3 produces an azimuth angle Ï(S) at P4. The invention comprises the control loop 252 having the transfer function shown, in which Á is the gain, T is a time constant selected to produce the desired result and S is the Laplace operator. Alternative circuits for 25 2  are described Figs.7A to 7C (not shown); they comprise operational amplifiers with RC feedback and a method of selecting suitable component values is discussed mathematically. Block 23 represents a north seeking device (not described) and 24 the torque about the vertical axis due to the rotation of the earth; the symbols represent the angular velocity of the earth and the instant latitude of the gyro. A term is added at 27 corresponding to the component of angular velocity of the earth about the vertical axis and another at 26 represents a torque about the horizontal axis produced by gravity on the unbalance of the gyro in the N-S direction. The invention is said to eliminate constant errors which occur in a purely proportional control system and arise due to temperature effects.

Abstract: 783,799. Foundations. NAAMLOOZE VENNOOTSCHAP ONTWIKKELING- MAATSCHAPPIJ MULTINORM. March 7, 1955 [March 10, 1954], No. 6677/55. Class 20(2) [Also in Group XXI] A foundation for supporting a building structure on soil strata having a solid bottom layer 3 at a relatively great depth capable of supporting the load of the building and covered by a weak upper layer 2 having substantially little load bearing capability, comprises piles 4 extending from the surface of the soil strata through the layer 2 at least down to the layer 3, each of said piles having a ratio of crosssection to length such that the portion of the load of the building which the pile is to support is greater than the load which would cause the pile to buckle if it were not laterally supported by the weak upper layer 2 but which is less than the load which would cause permanent deformation of the pile under compression when restrained from buckling by lateral support. In the examplified embodiment the piles, which may be metal rods 5 of circular, hollow or cross shaped section, are protected against corrosion by concrete collars 6 which extend downwardly to at least the lowest level at which underground water is expected. A concrete slab 14 cast over a sand bed 15 is connected to the rods 5 by web-like metallic structures which are connected to longitudinal and lateral reinforcement elements cast into the slab. The slab 14 is connected to the sheaths 6 by hook-like metallic elements previously positioned in the sheaths. The lower end of each sheath 6 is tapered to fit a conical collar closely slidable on the pile element 5 in order to prevent entry of matter into the bore of the sheath. In Fig. 6 the collar 24 is of double hopper shape the lower part of which is adapted to receive a conical stopper 23. The sheath 6, collar 24 and stopper 23 are drawn tightly together by means of wires 21, 22 extending up to the surface. The. metal pile elements may be protected against corrosion by coating them with bituminous or plastic compound. The pile elements may be made of reinforced concrete.

Patent GB-561642-A (GB)
Title: Improvements relating to the pigment dyeing of fabrics
IPC: D06P1/44
Filed: 1941-05-26
Abstract: Pigment colouration of a fabric is effected by saturating it with a pigmented water-in-oil emulsion, of which the aqueous phase constitutes at least 20 per cent by weight, and drying the fabric so saturated.  Advantageously, the oil or lacquer phase contains as binder a heat-convertible synthetic resin of the urea-formaldehyde, phenol-aldehyde or oil-modified alkyd type, in which case the resin is converted by heating into a form insoluble in washing and/or dry cleaning agents.  When a heavy finish is undesirable the binder content of the emulsion should not exceed 2 1/2 per cent and, to prevent flocculation of the binder in such an emulsion, a lacquer containing sufficient binder to prevent such flocculation may first be prepared and an organic phase containing little or no binder and with or without water may then be added to obtain a three-phase emulsion (cf. Specification 561,641).  In examples: (1) a cotton, cellulose acetate or viscose fabric is padded with a water-in-oil emulsion made by mixing an aqueous suspension of Lithosol blue GL into a solution of soya oil fatty acid-modified glyceryl phthalate resin in toluene, pine oil and hydrogenated petroleum, and the padded fabric is heated to dry the fabric and set the resin; (2) fabrics are coloured in a pigmented three-phase emulsion made by diluting the emulsion in (1) with an unpigmented emulsion obtained by mixing an aqueous solution containing sodium chloride, sulphonated tannin and acetic acid into a solution of a drying oil-modified glyceryl phthalate resin in hydrogenated petroleum and pine oil containing rubber; 93) fabrics are coloured in a pigmented emulsion made by diluting as in (2) a water-in-oil emulsion made by mixing an aqueous suspension of Benzidine yellow into a solution of a urea-formaldehyde resin in butanol, xylene and hydrogenated petroleum containing ethyl cellulose; (4) fabrics are coloured by applying thereto a pigmented emulsion made by diluting the water-in-oil emulsion in (3) or (5) with an unpigmented emulsion containing ethyl cellulose, pine oil, hydrogenated petroleum and water; (5) fabrics are coloured with a water-in-oil emulsion containing a urea-formaldehyde resin as in (3), a glyceryl phthalate resin as in (1), pine oil, hydrogenated petroleum, Monastral fast green GS and water; (6) fabrics are coloured with an emulsion made by diluting as in (2) or (4) a water-in-oil emulsion made by mixing an aqueous suspension of Benzidine yellow into a solution of a melamine-formaldehyde resin and the glyceryl phthalate resin of (2) in butanol, xylene and hydrogenated petroleum.

Abstract: 1,104,333. Pulp moulding. DIAMOND INTERNATIONAL CORPORATION. 18 Feb., 1965 [18 March, 1964], No. 7105/65. Heading B5A. Articles are made from a fibrous slurry by using a suction mould, part or all of the operative face of which comprises a perforated sheet of, e.g., metal or plastics having an open area of between 3 and 20%, the perforations of which sheet have diameters in the range 0-006 to 0À031 inch. This is stated to retard the passage of the liquid and thus a deposit is formed which is thinner than that formed by a conventional wire screen mould operating under the same conditions. In the embodiment shown in the Figure an egg carton (see Fig. 3, not shown), having separate posts thinner than the rest of the carton, is suction moulded using a die the operative face of which is made up of wire screen portions 12, and perforated metal portions 14 upon which a thinner layer of slurry is deposited to form the separator parts. Alternatively the thickness of the deposited layer may be varied by using a mould the operative face of which is wholly constituted by a perforated sheet, but in which the distribution and size of the perforations are varied from area to area.

Title: Improvements in ammunition hoists
IPC: F41A9/01
Filed: 1923-03-13
Abstract: 215,896. Armstrong, Whitworth, & Co., Ltd., Sir W. G., Lee, H. W., and Swindale, J. W. March 13, 1923. Loading-appliances.-Ratchet hoists of the kind described in Specifications 169,748 and 173,029 are provided at each end with a rotatable ammunition receptacle or scuttle in the form of two troughs 281, 282 placed back to back (see plan Fig. 3), one trough being in the receiving position whilst the other is in the delivery position, the rotation of the scuttle in contact with the inner surface of the hoist 10 under the action of a ratchet slider 11 serving to move the ammunition into and out of the hoist in flash-tight manner. Fig. 1 shows the arrangement of the upper end of the hoist. For the purpose of rotating the scuttle, the slider 11, which carries the lifting pawls 12 as described in the above-mentioned Specifications, is provided with a quick-pitched screw 14 for rotating a sleeve nut 15. This nut carries a spur wheel 171 gearing with a spur wheel 20 which rotates the shaft 231 of the scuttle through a bevel wheel 21 and clutch 23. When the slider 11 moves in one direction, the scuttle is rotated through 180‹, and when the slider returns the scuttle remains stationary to permit of charging and discharging the troughs. This intermittent motion is effected through the one-way clutch 23. The projectile 13 is taken from the scuttle and lowered into horizontal position by a tray 35 hinged to the hoist at 42 and rocked by a lever 40 engaging a cam groove 391 in a disc 39 driven through a counter-shaft and bevel gears from the wheel 20. A projection 392 on the cam disc also engages a roller 421, which through a link 43 rocks a hook 34 on the tray into engagement with the projectile to cause the projectile to descend with the tray. The projectiles may also be pushed from the troughs by levers 48 operated by a central rod 501 raised by a projection on the cam disc. The tray 35 is provided with a hinged flap 352 (see plan, Fig. 12), which is raised by a projection on the pivoted receiving-tray 45 to cause the projectiles to roll on to the receiving-tray. The troughs of the scuttles have spring retaining catches 29, Fig. 7, at the bottom, and the weight of the projectile acting on these catches causes upper catches 295 to project and retain the projectile in the receptacle. When the hoist is used for lowering ammunition, a lever 25 is operated to declutch the wheel 21, the scuttle being then rotated in the reverse direction by the wheel 26. The catches 29, 295 on the troughs at the top of the hoist are then arranged as shown in Fig. 8 so as to be disconnected by engagement with a member x connected with the clutch lever 25. Specifications 211,958 also is referred to in the Provisional Specification.

Abstract: 540,692. Pre-payment meters. BRITISH ELECTRIC METERS, Ltd., COOP, N. B., and WATKINS, B. T. E. April 24, 1940, No. 7400. [Class 27] In coin-freed pre-payment mechanism, more particularly for electricity meters, the movement of the quantity wheel, initiated by insertion of a coin and manipulation of a knob, &c., is completed by means operating from the moment of release of the knob independently of either the coin-or the knob, thus determining with greater accuracy the amount of commodity credited for each coin. The coinpocket member is formed of three discs c, a, b rotated by a knob 4, and has co-axial therewith a driven disc o furnished with four axial pins p and geared to the quantity wheel. Geared by a 12 to 1 reduction train t, u, v, w to the disc o is a disc r also provided with four axial pins s. Horse-shoe springs x take over the pins p, s, one spring for each set. Thus when on insertion of a shilling the disc o is given an eighth turn by the knob and coin, the spring x bears on the pin p to complete a full quarter turn. Insertion of a penny will allow of a partial turn of the disc r and its completion to a full quarter by its horse-shoe spring. A ratchet engaging stationary teeth prevents reversed rotation of the pocket c, a, b. The disc r is connected through pins f, m on levers e, rocked by the coin.
