Patent GB-399922-A (GB)
Title: Improvements in or relating to the manufacture and production of ceramic transfers
IPC: B41M3/12
Filed: 1932-05-27
Abstract: 399,922. Transfers. ALLEN, L. and JOHNSON, MATTHEY, & CO., Ltd., Sneyd Colour Works, Burslem, Staffordshire. May 27, 1932, No. 15125. [Class 100 (ii).] Transfers for use in the decoration of glass, porcelain, pottery, enamelled ware, or the like are prepared by printing the design in one or more colours on paper coated with a film of plastic material containing a vitreous flux. The plastic material is such that it burns away on firing, and may be composed of collodion, cellulose acetate, resins; varnishes, or the like. A coloured or colourless flux, which fuses at a relatively low temperature and which is preferably finely divided, is mixed with a solution of the plastic material, and the suspension is applied in a thin film to a gummed sheet of backing-paper ; if desired a pigment, to produce a coloured, clouded, opaque, or translucent effect as a background to the design, may be added to the plastic material. The design is then printed in one or more colours on the plastic film, and, after drying, the backing is removed by soaking with water and the film is applied, printed side upwards, to the article to be decorated, which is subsequently fired. In order to prevent running of the colour into the flux, colours having a higher softening- point than the flux are preferably employed, although more fusible colours may be used if there is no tendency to diffuse. The printing- colour need contain no flux, since flux is incorporated in the plastic film. The colouring- matter may be prepared by fusing a mixture of pigment and flux, grinding the product to powder, and removing the finest particles to leave a granular material which readily adheres in a smooth coating to the vehicle of the printing-composition.

Title: Improvements in internal combustion engines
IPC: F01L1/42
Filed: 1919-06-17
Abstract: 149,491. Scott, B. D. June 17, 1919. Regulating; valves; valve-gear.-In an aircraft engine in which air is admitted during the first part of the suction stroke and a rich mixture is then admitted near the crank case end of the cylinder, an adjustable proportion of the air charge is expelled from the cylinder during the earlier part of the compression stroke in order to keep the power constant at all altitudes. Fig. 1 shows the invention applied to a radial cylinder engine of the kind described in Specification 4769/15, in which a single valve in each cylinder operated by tappets such as a serves for exhaust and for the admission of a variable quantity of air during the earlier part of the suction stroke, a rich mixture being admitted through ports overrun by the piston. In the Specification referred to, the tappets a are lifted during the exhaust stroke by cams or projections on a wheel d running on an eccentric f on the shaft and engaging internal teeth i on the casing, and a similar wheel c lifts the tappets during the first part of the inlet stroke. According to the present invention, a third similar wheel m is provided, having coned or tapered projections p for lifting the valve during the compression stroke, and this wheel m is adjustable axially on the shaft for varying the extent of lift. The adjustment may be effected by a quick-threaded screw v.

Title: Improvements relating to shock absorbers
Inventor: KENYON DENNIS
IPC: F16F9/49
Filed: 1968-04-01
Abstract: 1,267,508. Shock absorbers. WOODHEAD MFG. CO. Ltd. 25 March, 1969 [1 April, 1968], No. 15543/68. Heading F2S. The piston 8 of a shock absorber experiences an initial resistance to its movement into the cylinder 1, which is reduced or eliminated after an initial movement of the piston into the cylinder. The resistance is provided by a subsidiary piston 9 which is joined to the main piston 8 and slides in a subsidiary cylinder 25 at the beginning of the contraction stroke and at the end of the extension stroke. When the main piston 8 begins to move into the cylinder (R.H.S. of Fig. 2) the O-ring 38 seats against the upper part 34 of the subsidiary piston 9 and so fluid between the pistons can only escape to the back of the piston 9 by way of bleed notches 44 (optional). When the subsidiary piston reaches the end of the cylinder 25, the threshold resistance is eliminated, and further movement of the piston 8 is regulated by valve elements 15, 16 and bleed notches 17. The position at the end of the extension stroke is shown in the L.H.S. of Fig. 2. The 0-ring 38 allows substantially free flow of fluid from the subsidiary cylinder. The working fluid is an emulsion of liquid and gas under pressure.

Abstract: 810,478. Electro-magnetic measuring apparatus. FERRANTI Ltd. May 25, 1956 [May 31, 1955], No. 15563/55. Drawings to Specification. Class 40 (7). [Also in Groups XXXVIII and XL (b)] In an arrangement for determining the extent and sense of the movement of one object relative to another employing the arrangement described in Specification 760,321, [Group XL (b)], in which a cyclic wave pattern is established the movement of which is related to the movement to be determined and in which two detecting devices, fixed relative to one of the objects (and the moving pattern) and so spaced that the respond to quadrature phase conditions of the pattern and produce electrical signals differing in phase by 90 degrees, these signals being supplied to discriminating and counting means which provide the required information, detrimental effects on the accuracy of the measurement caused by variations in the means for setting up the cyclic wave pattern (i.e. brightness variations when this is an optical diffraction pattern) or, in the sensitivity of the detecting devices, are eliminated by employing an additional pair of detecting devices also spaced to respond to quadrature phase conditions of the pattern and spaced relatively to the first pair so as to be individually responsive to counterphase pattern conditions relative to respective ones of the first pair. The output signals of the counter-phase devices (one of each pair) are then combined and the two sets of signals supplied to respective difference amplifiers the outputs of which are proportional to the difference between the D.C. levels of the input signals, no output appearing if, e.g. due to a change in the overall patter, the level of the input signals changes by equal amounts in the same direction. In this manner the difference amplifiers only supply output signals when the input signals vary due to relative movement between the two objects and these signals are then converted into pulses which are employed in the pulse discriminating and counting arrangement described in the above mentioned application to provide the required information. In the described embodiment the cyclic wave pattern is an optical one but it is stated that a recorded magnetic pattern or an electromagnetic or acoustical standing-wave pattern may be employed instead, the detecting devices being appropriate to the kind of energy utilized.

Title: Improvements relating to electric regulating devices
IPC: H02P9/24
Filed: 1926-06-22
Abstract: 278,060. British Thomson-Houston Co., Ltd., and Parry, R. D. June 22, 1926. Regulation, automatic.-Relates to an automatic regulating system for a dynamo-electric machine of the kind in which a resistance is arranged to be cut in and out in series with an excitation circuit associated with the machine. The invention consists in the use, in place, of the usual relay or relays for cutting the resistance, in and out, of a space-current device which has its output circuit connected in shunt with the resistance and has its control circuit responsive to variations of the conditions to be regulated. Fig, - 1 shows the application of the invention to the voltage regulation of a synchronous alternator 4 controlled by a Tirrill regulator 15. The shunt field winding 8 of the exciter 7 is connected in series with a rheostat 9 and also to the anodes 10 of a pair of triode space-devices 11. The grids 12 of these devices are interconnected and coupled through the lead 13 to the contacts 14 of the Tirrill regulator. Lead 16 connects the contacts 14 to the negative side of a biassing battery 17, the positive side of which is joined by a lead 18 to the cathodes 19. The current passed through the space-devices 11 in shunt to the rheostat 9 is decreased proportionally as the " dwell " of the contacts 14 increases, and viceversa. In a modification, the Tirrill regulator is replaced by a regulator with a single moving contact, the electromagnet, of which is energized by rectified current taken from the alternator load circuit 5 through a pair of rectifying thermionic valves, for example, as described in Specification 232,641. Specification 147,806 also is referred to.

Title: Navigation system
IPC: G01C19/36
Filed: 1949-06-14
Abstract: 668,401. Electric navigation systems. BENDIX AVIATION CORPORATION. June 14, 1949. [Nov. 22, 1948] No. 15852/49. Class 40 (i). The readings of a pointer electrically controlled by a gyro compass attached to a craft are corrected by means of a magnetic compass operating through an electrical differential device. As shown, the gyro 10 mounted in conventional manner has a 3-phase rotor winding 18 attached to its vertical outer trunnion 15 so that with relative motion between the gyro and the craft voltages are induced in winding 18 from a 3-phase stator winding 19, which are fed to a 3-phase stator 25 associated with a rotor 23 attached to a shaft 22 having a pointer 20 and dial 21. The voltage induced in winding 23 is led through an amplifier 28 to one winding 30 of a 2-phase motor 31 which drives the shaft 22 through gearing 33 until the voltage in winding 23 is eliminated. The pointer 20 thus indicates the angular displacement between the gyro and the craft. A further winding 48 on shaft 22 is associated with an earth inductor compass 34, so that if the rotation of the shaft 22 is not the true angular movement of the craft, a voltageis induced in winding 48 which after amplification at 49 causes a 2-phase motor' 53 to drive a shaft 70 through independently selectable fast or slow gearing to alter the voltage induced in 3-phase stator 57 from an energized rotor 55 attached to shaft 70, the stator 57 feeding a further stator 19 which energizes the rotor 18 attached to the gyro trunnion 15, thus modifying the rotation of shaft 22. The shaft 22 may be connected via known transmitters to remote receiving stations, or a suitable inductive device 82 may be connected from shaft 70 to an indicator via electrical differential device 85. Specification 662,831 is referred to.
