Title: Improvements in or relating to covering material and methods of decorating the same
IPC: D06N7/00
Filed: 1929-08-16
Abstract: 338,205. Armstong Cork Co., (Assignees of Prentis, H. W.). Oct. 9, 1928, [Convention date]. Rugs and mats.-A method of decorating hard surface covering materials such as linoleum and felt base material consists in producing a succession of rug patterns on one side of a strip of material, and applying a running pattern to the other surface so that the strip can be cut up into a number of individual rugs or mats without difficulties due to non-registration of the patterns. Cross borders may afterwards be applied to the running pattern. Preferably the coatings applied to the two sides are such that their coefficients of expansion are the same. The rug patterns may be applied by printing, and the running pattern by spraying. The web of material is printed on one side in a block printing machine, for example, with a series of patterns such as shown in Fig. 4. After drying, the material 6, Fig. 2, is passed under a battery of sprayers 7, and under a roller 8 which prints borders 9 on the back of the material. The length is then cut up into mats at the edges of the pattern on the front, and the pattern on the back is completed as shown in Fig. 3 by printing or brushing on borders 10. Rugs or mats are thus made reversible.

Title: Improvements in winches or hoisting mechanism
IPC: B66D1/26
Filed: 1922-09-18
Abstract: 187,210. Sullivan Machinery Co., (Assignees of Holmes, M. P.). Oct. 8, 1921, [Convention date]. Winches; driving-gear; apparatus with jointly. controllable drums.-In winches of the type in which a motor arranged between two coaxial drums drives them through independent driving connections, the adjacent ends of the winding drums overlap the ends of the motor and may have a bearing on the motor casing. In the illustrated form, two arms 7, 8 in axial alignment, journaled at their outer ends in ball bearings in standards 2, bear at their inner ends upon the fixed casing of a fluid-pressure motor, from which each drum is driven independently through different sets of epicyclic gearing. The motor is of known form having two intermeshing toothed rotors 14, 15; fluid being admitted by the pipe 17 to the spaces between the intermeshing teeth and being exhausted through the ends of the casing. One of the rotors carries a pinion 22 at each end of the shaft, each pinion forming the driving member of identical sets of epicyclic gearing, one set being applied to each drum. The pinion 22 gears with one wheel of a pair carried by a stub shaft in alignment with the axis of the drum. The other wheel 30 of this second pair is located outside the end wall of the drum and gears with a wheel 31 mounted on another stub shaft in the end wall of the drum. The wheel 31 gears with a toothed ring 35 that can be held by a brake at will. When either ring is braked, the corresponding wheel 31 functions as a planet pinion and carries the drum round bodily with it. By manipulating the two brakes, either or both of the drums can be driven or the gearing allowed to run free without rotating the drums, although the motor is rotating constantly.

Title: Electrical phase comparison circuitry
IPC: G01S1/02
Filed: 1956-08-17
Abstract: 803,130. Phase, voltage measurement. STANDARD TELEPHONES & CABLES, Ltd. Aug. 17, 1956 [Aug. 23, 1955], No. 25219/56. Class 37. [Also in Group XL (c)] An input at 19a is applied to the anode of one valve and cathode of a second valve, both connected in series, and a second input at 19 applied to the grids of both valves, so that the voltages derived across cathode resistors 52, 50 of the valves, connected to earth, are equal when the instantaneous amplitude of the A.C. input at 19a is zero, but unequal otherwise in a magnitude and sense dependent on the phase difference due to the valves conducting unequally. Both outputs after smoothing by circuits 31, 30, are then applied to the respective grids of triode valves 35, 34 with meter 52 connected between the cathodes, forming a valve voltmeter, with balanced cathode circuits formed by resistors 42, 43, 46 and potentiometer 44. Grid current flow ig24, ig23 in each valve 24, 23 equally varies therefore in the same direction the cathode output voltages of the valves, with no effect on the meter 52, in which zero current flow, for equality of input signals to grids 32, 33 and phase-correspondence between signals 19, 19a. The circuit may be applied to a receiver in an aircraft navigation system as described in Specification 785,708, [Group XL (c)], in which a rotating aerial beacon transmits a rotating radiation pattern having a sinusoidal component of frequency equal to the pattern rotation frequency detected at the input 19a and also a pulsed reference signal when the radiation passes a particular direction detected as the input 19. The derived sinusoidal frequency may be applied through a phase-splitter to opposite ends of a double-arm potentiometer, the ganged arms of which respectively include a capacitor and resistor connected to a common terminal with output at the terminal of constant amplitude but adjustable phase. After adjustment until the valve voltmeter gives a null deflection, the phase difference is then read from an indicator connected to the potentiometer. Specification 792,700, [Group XL (c)], also is referred to.

[Also in Group XXXIII] An aerial toy, e.g. a bird, insect or glider, is provided with a sound emitting device having a portion made of substantially inextensible sheet material such as paper which vibrates and emits sound when the toy is in flight. As shown applied to a toy glider made of heavy paper or cardboard, a paper strip 20, Fig. 1, fixed at one end to a glider wing, has its other end bent. to form a wind vane 23 while the other wing has another sound emitter 24 attached thereto at both ends and having forward and rearward projections which may be bent upwardly or downwardly. Alternatively the emitters may be the same on both wings. Further sound producing means in the form of vibrators 28 and tilted vanes 33 on an adjustable tube 32 on the nose of the glider are said respectively to give increased lift to the glider in flight and to steer it sideways or vertically. In other arrangements a strip or band of material secured at both ends may have a central fold to contact the wing on vibration, or have slots 44, Fig. 6, to increase the sound emitted, or it may have a forward limb 59, Fig. 10, secured to the glider or toy to limit the uplift of the central portion. Fig. 8 shows another form of glider with a sound emitter comprising a rubber band 53 with a tail portion 54 of inextensible sheet material and in Fig. 11 a sound emitting strip 63 braces the wings. In further forms the vibratable pieces may be loosely connected to the wings by cords passing through holes in both or may project forwardly or rearwardly of the wings with anchorage at one end only. The sound producing pieces may be located above and below the toy and in one embodiment two such pieces are connected together and mounted on the toy by pins driven into the wings. The glider may be projected by a rubber band or spring or may be swung around on a string and it is kept facing the direction of movement by means of a weight 65, Fig. 8, in the nose or by an extension 66 of the fuselage, Fig. 1.

Title: Antenna system
IPC: H01Q9/26
Filed: 1970-05-27
Abstract: 1312965 Aerials SCANWELL LABORATORIES Inc 27 May 1970 [11 July 1969] 25566/70 Heading H4A A VOR aerial comprises four closely spaced aerial arrays, each including four elements of hollow construction mechanically joined at their extremities in an orthogonal configuration, corresponding elements of said four arrays being substantially parallel. As described, each array 40, Fig. 3, comprises four hollow tubular radiating elements 50-53 which are joined together at corners 60-63 in a flat, approximately square configuration. Hollow tubular radial arms 66-69 extend in the plane of the radiating elements from the said corners to a central junction 65, in which is a terminal for a main coaxial feeder 70 and for branching coaxial feeders 71-74. The radiating elements 50-53 have balun gaps 54-57 at approximately their mid-points, and the branching feeders pass via the radial arms to said gaps. For example, the feeder 72 passes through the arm 66 to enter the radiating element 51 at the corner 61, and extends to the gap 55. Its outer conductor 75 is connected to the upper side of the gap and its inner conductor 76 crosses the gap and is connected to the lower side thereof. An impedance compensation network is shown at 77. The radial arm 68 is continued outside the square configuration loop and provides means whereby the device 40 is bolted in a horizontal position to a vertical hollow mast 35, the feeder 70 being taken down said mast. It is stated that planes passing diagonally through the corners of the loop are at zero potential, and hence the mast 35 has little effect on the horizontally polarized radiation from the loop. An aerial array 30 for VOR transmission comprises the loop 40 together with three other identical loops 41-43, the four being symmetrically disposed around the mast 35. A number of such arrays may be arranged one above the other on a vertical mast in order to obtain a shaped radiation pattern having minimal radiation below the horizontal plane of the lowest array (Fig. 2, not shown), and a suitable distribution system is described (Fig. 5, not shown).
