Title: Improvements in railway signalling and collision prevention apparatus
IPC: B60T7/18
Filed: 1919-06-05
Abstract: 156,830. Wright, W., Weiss, B., Connolly, P. A., Phillips, W. O. J., and Langford, L. June 5, 1919. Track apparatus actuating signals on trains and for stopping trains. -A lever 20<t> on the train engages the underside of a track rump if the track is clear and is raised by the upper side of the ramp if a danger condition exists. The ramp has pivoted front and rear sections and a fixed main section. At a clear signal, the arm 20<t> passes below the ramp and a press stud closes a switch 20a in the circuit to a bell Z and a clear lamp G. At a danger signal, the arm 20t is raised and is held up by a catch, which may be released by the operation of the plunger 30<e> by the driver. The flag 31<a> is moved to expose a danger lamp 31b and the valve, which is rigid with the lever 20t, exhausts the brake pipe and one end of the cylinder 32a so that the pressure on that side escapes and the piston moves to close the throttle under the pressure on its opposite side. On restoration of the lever 20t, the pressure on both sides of this piston is equalized.

Abstract: 544,002. Treating fabrics containing cellulose derivatives. BRITISH CELANESE, Ltd. Sept. 21, 1940, No. 14425. Convention date, Sept. 21, 1939. [Class 2 (ii)] [Also in Group VIII] In processes of the kind in which semi-stiff or stiff laminated fabrics are obtained by treating two or more layers of textile fabric, one of which at least contains a cellulose derivative, with a solvent for the cellulose derivative and then applying heat and pressure to unite the layers, the solvent is applied to the fabrics in the form of vapour. The layer containing a cellulose derivative may be a fabric made wholly or partly of a cellulose-derivative yarn or a fabric made wholly of non-thermoplastic yarn to which a coating of a cellulose derivative has been applied in the form of a powder or a slurry or a solution. Solvents specified comprise acetone, methyl-ethyl ketone, methyl alcohol, dichlorethylene, ethylene dichloride, tetramethyl ene oxide or mixtures thereof. The cellulose derivative is preferably treated with a plasticizer, e.g. dimethoxyethylphthalate, triacetin or di-ethoxyethylphthalate, which may be applied in a solvent, e.g. benzol or ethyl or methyl alcohol. The yarns, or the coating containing a cellulose derivative which may be applied thereto, may contain pigments, e.g. titanium oxide, lead oxide or carbonate or iron oxide. In an example a fabric consisting of 20 per cent. of yarns of cellulose acetate containing a pigment and of 80 per cent. cotton yarn is dipped in a mixture of dimethoxyethylphthalate, triacetin and alcohol. The fabric, after evaporation of solvent, is interposed as an intermediate layer between two layers of broadclotb cotton fabric, and the layers cut into the form of a collar are placed in a vessel containing at the bottom thereof a mixture comprising 75 per cent. acetone and 25 per cent. methyl alcohol, which is vaporized by heating. After subjection to the vapours for thirty minutes the treated fabrics are pressed at 125-139‹C. under a pressure of 40-85 pounds per sq. inch. The Specification as open to inspection under Sect. 91 describes the treatment of a single layer of fabric. This subject-matter does not appear in the Specification as accepted.

Title: Electrical circuit breakers
IPC: H01H83/22
Filed: 1972-03-28
Abstract: 1390987 Automatic circuit-breakers BROWN BOVERI & CIE AG 28 March 1972 [29 March 1971] 14529/72 Heading H1N A single-pole or multi-pole excess-current responsive circuit-breaker (not shown), is provided with an attached earth-leakage component comprising a tripping mechanism, energy storage means, a resetting member 13 and a coupling member 14 mechanically coupled to the circuitbreaker such that the circuit-breaker can only be in its set or reset condition when the leakage component is set ready to perform a tripping action, e.g. should an attempt be made to close the circuit-breaker when an earth fault exists. As shown, the resetting lever 13 and a link 19 form an over-centre toggle linkage connected by a wire stirrup 20 to a motion-transmitting lever 23, one end of the stirrup sliding in a slot 21 in a locking lever 22. When earth leakage occurs, the armature of a device responsive to the leakage current moves a pin 29 to cause a lever 30 to pivot the arm 31 of a latch 32 so that the latch 32 releases the locking lever 22. This lever initially moves in a clockwise direction so that the end of the stirrup can move from the latched position of Fig. 3, along to the other end of the slot. This enables the spring 24 to force the lever 23 down into the position of Fig. 4, the lever 23 turning the coupling member 14 to trip the circuit-breaker. Resetting of the component by the lever 13 to the condition of Fig. 3 is necessary before the circuit-breaker can be reset.

Title: Colour hue control circuit for colour television receiver
IPC: H04N9/00
Filed: 1977-04-06
Abstract: 1527453 Colour television SONY CORP 6 April 1977 [12 April 1976] 14605/77 Heading H4F A hue control circuit is designed to permit manual adjustment of the hue and to maintain that hue irrespective of phase distortion in the colour sub-carrier As particularly described the received television signal includes a phase reference (VIR) signal in a certain line period of each vertical retrace period, and, during adjustment, the display carries part of the received picture, an invariant colour bar generated in the receiver and containing red, blue and green areas, and a variable colour bar which is contiguous with the invariant bar and which varies with the hue adjustment. In one embodiment, Fig. 3, the chrominance component of a received NTSC signal is separated 5 from the luminance signal and passed to demodulators 6, 7. The colour burst is separated 8 from the chrominance signal and controls an oscillator 10 which passes a sub-carrier frequency via variable phase shifter 11 and 90 degree phase shifter 12 to the demodulators. The demodulator outputs and the luminance component are used 13, 14 to provide colour signals R, G, B to the C.R.T. display. The (R-Y) output of demodulator 6 is also fed to a sample and hold hue control circuit 27 which varies the phase shifter 11 from 90 degrees in accordance with the level of the (R-Y) signal during the VIR signal 15, 16, 33 in the vertical retrace, thereby maintaining the hue irrespective of phase distortion. The hue selected is alterable by manual adjustment 31 of the circuit 27. Invariant colour bar signals generated 18 in the receiver pass via switches 23, 24, 4R, 4G, 4B, 4Y and matrix 14 to the display. The switches are controlled by pulses derived 17 from the vertical and horizontal sync pulses ensure that the colour bar appears at the required position on the display. The invariant colour signals also pass via variable amplifiers 21, 22 the switches and the matrix to the display. The gains of the amplifiers alter in accordance with the manual adjustment 31 of the hue control circuit 27, so that the variable colour is displayed for visual comparison with the adjacent invariant colour bar.

Abstract: 719,264. Agricultural implements. BROWN TRACTORS (ENGINEERING), Ltd., D. June 15, 1953 [June 13, 1952], No. 14901/52. Class 6 (1) Relates to one-way ploughs of the type having bodies g, h of opposite hand mounted on beams e, f pivoted at their front ends upon a common transverse shaft b, the beams being interconnected so that as one rises the other falls. According to the invention, the beams are carried by a frame a raisable bodily by the towing tractor and the beams are interconnected by means attached to the tractor so that bodily raising of the frame causes the interconnecting means to slacken to permit both ploughs to assume a side-by-side transport position, a bolt o being slidable over either beam in this position to cause it to become the operative body on re-lowering the frame. The interconnection may comprise a cable k passing around a sheave n on the tractor, from which the frame a is suspended by power-operated draught-links. The bolt o is movable by a hand lever p accessible to the tractor-driver. In a multi-body plough (Fig. 3, not shown), the separate beams of the same hand are locked by cableinterconnected latches. In a modification, the sheave and cable are replaced by a pivoted T- shaped link having its ends linked to the respective beams. Each body may have its corresponding cou'ter i, but in one form a single disccoulter is mounted on the main frame and pivoted about a longitudinal axis. The beams engage resilient abutments on the coulter-mounting to swing the coulter into operative relation to the working body, Fig. 6 (not shown).

Abstract: 947,591. Rolling. UNITED ENGINEERING & FOUNDRY CO. April 28, 1960 [April 30, 1959], No. 14912/60. Heading B3M. A mill for reducing strip of uniform thickness comprising a pair of small diameter work rolls 14, and large diameter back-up rolls 15, 16 for supporting the work rolls includes means for applying to said backup rolls a force of a controlled magnitude to eliminate camber and maintain the strip thickness constant. The back-up roll 15 is supported at the ends and adjusted to define the pass by screwdowns 21 operated by wormwheels 22 and is further supported by a roll 25 journalled in a vertically slidable frame 27. Variable pressure is applied to the frame 27 by fluid cylinders 31, the particular pressure used being related to the dimensions and properties of the strip in the pass and is sufficient to eliminate the camber of the working rolls. A roll 32 applies a similar pressure to the backing roll 32. Fluid is supplied to cylinders 31, 36 by a variable pressure pump 38 driven by a variable speed motor 39. The rolls may be uncrowned or crowned, in the instance the rolls 25, 32 compensate for the latter thickness error due to using a given crown under varying conditions of rolling, e.g. varying properties and dimensions of strip. The frame 27 is supported by a cylinder 28 and the chocks of both the backing and the working rolls are biased apart by cylinders 41, 42 respectively. In a modification, the screwdowns 21 are replaced by fluid cylinders acting on the chocks of the back-up rolls, the cylinders being supplied by a pressure pump driven by a variable speed motor.

[Class 40 (v).] Comprises circuit arrangements for eliminating the effect of disturbing currents on a mains-driven receiver introduced therein from the supply mains. The receiver Z<1> is supplied with cathode-heating current from the mains X, X<1> through circuits Z, D respectively. The circuit Z comprises a fixed or variable inductance with or without a variable condenser in parallel or a band-pass filter and a variable resistance R and condenser in series, arranged in parallel therewith. The circuit D comprises an inductance or arrangement of inductances and a variable resistance R<1> and condenser in series, arranged in parallel therewith. Loading impedances L, L<1> may precede the circuits Z, D in the leads X, X<1>. The circuits Z, D are connected to the receiver Z<1> by leads a, a<1> respectively, the lead a, or the lead a<1>, being earthed through a condenser C<3> and resistance R4. The resistances R, R<1> may be replaced by another earth connection, for example R being replaced by the natural resistance between an earthing point T<1> to which the circuit Z is connected through a condenser C<4> and the earthing point T. R<3> is the impedance between the line X and earth and can be regulated by the value of L or by the efficiency of the line earthing connection. Condensers C<1>, C<2> bridge the mains. A circuit such as Z or D mav replace the impedance normally found between the lead a and the cathode-heating circuit of the receiver. When the cathodes are not supplied from the mains, the leads a, a<1> are connected to the cathodes through condensers. A variable condenser K<1> is connected between the aerial and the main lead X. It is shown in the Specification that the receiver Z<1> may be regarded as being in one diagonal of a Wheatstone bridge, of which the other diagonal is supplied with the interfering currents, the four arms of the bridge being constituted by the condenser K<1>, the circuits Z, D in parallel, the resistance R<4>, and the natural capacities between aerial, mains and earth.

May 15, 1930, No. 15007. [Class 40 (iv).] In a loud-speaker or like electromagnetic vibratory device of the cantilever reed type in which the vibrating element or armature d is connected to its support or main lim a by means of a relatively thin flexible U-shaped portion c, the armature and the U-shaped portion are formed integrally while the thickness of the U-shaped portion is a minimum at a point e on that side of the centre line A .. A of the U which is remote from the vibrating element d. As shown in Fig. 2, the centre line A .. A is at right-angles to the plane of the armature, but it may be inclined thereto either at an acute or obtuse angle. In assembling the armature in a loud-speaker unit, Figs. 1 and 5, the armature d is connected to the diaphragm by an actuating rod n encased in a rubber sleeve q and is positioned above the air gap r of a magnet f having tapering polepieces g around which are wound the speech coils h. The supporting limb a of the armature is secured both to the centre of a resilient U-shaped member l, the ends of which are mounted on the polepieces g, and also to a rigid pillar j formed integrally with a baseplate k that is adjustable by means of a knob m. On rotation of this knob the armature d is adjusted towards or away from the polepieces g against the resiliency of the member l. When the loud-speaker is in operation, by virtue of the shape of the part c, the armature d is capable of vibrating both in a direction towards and away from the polepieces and also in a plane perpendicular to this.
