Patent GB-131686-A (GB)
IPC: F41A25/02
Abstract: 131,686. Compagnie des Forges et Acieries de la Marine et d'Homecourt. Jan. 15, 1918, [Convention date]. Recoil apparatus.-Relates to means for varying the length of recoil in accordance with the elevation, of the kind in which the lift of the spring- controlled throttling-valve 6 is governed by the position of a stop 13 which is under the influence of wedges 16, 17 operated during the elevation of the gun by means such as a pin 18 on the wedge 17 engaging a fixed cam 19. According to the invention, elastic means such as Belleville washers 15 are interposed between the stop 13 and the wedges so that for long recoils only the weak valve spring 8 is operative, whilst for short recoils the spring load on the valve is increased by the movement of the stop 13 against the action of the spring 15. The movement of the valve for long recoils may be limited by a stop 25, but in a modification this stop is dispensed with and the spring 15 is placed under initial compression.

Abstract: 441,746. Directive wireless signalling. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. May 8, 1935, No. 13556. Convention date, May 8, 1934. [Class 40 (v)] The modulation of a radio-beacon of the overlapping-field type, particularly when used to enable a pilot to make a " blind " landing at the aerodrome, is so arranged that the same indication is given for a deviation, say to port, irrespective of the direction of the flight. As shown, the field distribution from an aerial S is varied from K1 to K2 by reflectors R1, R2, as described in Specification 405,727. If, owing to varying wind conditions, the direction of approach is changed from the arrow 1 to the arrow 2, the keying of the aerial S is switched over by the aerodrome operator so that the pilot always receives a " dot " signal if he deviates to starboard, and a " dash " for port. The keying device may be linked through a single switch with the preliminary signals transmitted from the boundary-marking beacons V1, V2 or V3, V4.

Abstract: 1,081,666. Sheet stacking apparatus. COMPAGNIE DE SAINT GOBAIN. March 29, 1966 [March 29, 1965], No. 13793/66. Heading B6H. Glass sheets delivered by a roller conveyer 2 (Fig. 1) on to a tilting table 4, provided with a number of supporting rollers 33 (Fig. 3) and a pair of abutments 5 against which the leading edge of the sheets is temporarily arrested. are stacked on to stand 8 in inclined, face-to-face relationship by pivoting the table 4 from the horizontal position into an almost vertical position and moving the table forwardly towards the stand 8 until rollers 11 on the abutments 5 come into contact with the surface of the last stacked sheet 1 (Fig. 3). Continued pivoting of the table causes the leading edge of the sheet to contact the surface of the last stacked sheet, whereby the combined pivotal movement of the table and weight of the sheet abutting against the abutments 5 causes the latter to move arcuately in slots 14 distending springs 25 and moving between the steadies (not shown) on the stand below the plane of the stacked sheet edges to deposit the sheet, which is now in surface contact with the last stacked sheet, on the steadies. Action of springs 25 subsequently returns the abutments to their original position in the slots 13. Surfaces of rollers 11 and abutments 5 are covered with rubber.

Title: Improvements in or relating to television receivers
IPC: H04N3/24
Filed: 1959-04-23
Abstract: 896,685. Television. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 23, 1959 [April 26, 1958], No. 13876/59. Drawings to Specification. Class 40(3). Received television signals having a given aspect ratio (e.g. 3:4) are reproduced in an area of a picture tube screen having a different aspect ratio (e.g. 4:5) by reducing the amplitude and increasing the fly-back time of the line scanning saw-tooth wave (the vertical scanning remaining unchanged) and blanking the beam during such increased flyback time. The Specification discusses a typical arrangement in which, with a given linefrequency saw-tooth wave generator, the flyback period is increased from 15% of the line period (625 line viewbeam standard) to 23.15% by triggering the line generator at the reduced amplitude portion of the sawtooth wave required by the change in aspect ratio of 3:4 to 4:5 and shows that such operation results in a reduction of nearly 50% in the currents in the output valve and the series booster diode of the line deflection saw-tooth generator. The blanking pulse for the increased fly-back period is derived from an auxiliary winding on the line output transformer.

Title: Improvements in printing cotton fabrics and yarns
IPC: D06P5/15
Filed: 1919-06-05
Abstract: Discharge effects are obtained by first mordanting cotton fabrics or yarns with tannate of aluminium, iron, or chromium, then printing on a thickened solution of caustic alkali, to which may be added vat or sulphur dyes and a reducing-agent, or an alkaline mordant such as sodium aluminate or an alkaline lead solution, or both, then ageing or steaming, washing or otherwise preparing for dyeing, and finally dyeing with colours appropriate to the mordants used.  The initial mordanting may be effected by first applying aluminium, iron, or chromium mordants and then dyeing, padding, or printing with tannin, or vice versa, or the metal salt and tannin may be applied simultaneously.  Other colours, e.g. aniline black, vat or sulphur dyes, or diazo compounds (on fabric prepared with b -naphthol), or other discharges, may be applied at the same time.  Glucose, glycerine, or tannin may be added to the alkaline discharges. According to examples:-fabric is chrome-mordanted by the process described in Specification 117,715, tanned, printed with the alkaline discharge, aged, washed, and dyed; fabric is padded with a solution of tannin and potassium chlorate, padded with iron acetate, printed with the alkaline discharge, aged, washed, and dyed; fabric is printed with a mixture containing iron acetate, tannin, acetic acid, hydrosulphite NF cone, and starch-dragon thickening, aged, washed and soaped, printed with the alkaline discharge, aged, washed, and dyed; fabric is padded with a solution of tannin and potassium chlorate, printed with iron acetate and aluminium acetate simultaneously, aged, washed, and soaped, printed with the alkaline discharge, aged, washed, and dyed.

Title: Air brake systems
IPC: B60T8/50
Filed: 1976-04-08
Abstract: 1495917 Anti-skid vehicle air brakes GENERAL MOTORS CORP 8 April 1976 [8 May 1975] 14275/76 Heading F2F The air supply line 50, 54 from a supply source 22 to a braking relay valve 32 passes through a selective restrictor 36 which is effective when actuated by operation of an anti-skid electrovalve 30 to delay the build-up of supply pressure to the relay valve 32 and hence to vehicle brakes. Normally pilot pressure from a driver's valve 12 is supplied to a smaller area side 48 of a piston 94 via the electrovalve 30, the relay valve 32 and a passage 46 and this pressure together with the supply pressure acting on the piston plunger end 100 holds the piston against the reduced pilot pressure acting on the larger area side 40 of the piston and supplied via a fixed restriction 44 thus opening the supply passage 90, in addition to the permanently open passage 92. On actuation of the electrovalve 30 by a skid signal the pilot pressure lines 34 and 46 are vented to atmosphere while the inlet 58 to the valve is closed. Thus the increasing pressure through the restriction 44 displaces the piston 94 closing the passage 90. In addition a seal (232) (Fig. 4, not shown) on the smaller side of the piston engages an edge (230), so that when the electrovalve opens again the pilot pressure acts on too small an area of the piston to displace the valve again and the passage 90 remains closed. On release of the driver's valve 12, the chamber 40 is vented also and the supply pressure raises the piston 94. The relay valve 32, Fig. 3, includes a piston 106 separating the pilot pressure chamber 112 from a chamber 110 with an outlet 122/72 to brake actuators which as shown are vented through apertures 141 and a one-way valve 142, and having a valve seat 120 engageable with an element 140 of a slidable tube 136 to lap and then displace it from a fixed seat 118 of the housing to separate the actuators from the vent and connect them to a passage 70 connected to the restrictor 36 and the air supply source.

Abstract: 462,429. Spray carburetters. SOC. ANON. SOLEX. May 20, 1936, No. 14286. Convention date, Dec. 5, 1935. [Class. 7 (iii)] [Also in Group XXVI] An unbalanced valve 4 is fitted in the induction pipe 1 of an internal-combustion engine and is adapted to close under the flow of gases in the pipe and is loaded in the direction of opening by a spring 6. The abutment 8 of the spring is adjusted by a lever 10 connected to a diaphragm 14. A pipe 19 leading to chamber 15 may be connected to any part of the induction pipe 1 and the other side of the diaphragm is exposed to atmospheric pressure or a constant pressure. The lever 10 is connected by a spring 22 to a hand lever 20 adjustable between stops 23, 24, a pedal 25 is connected by a rod 26 and springs 30 to a lever 27 connected through a lost motion device to the valve 4. Excessive movement of the lever 25 in one direction causes the abutment 32 to close the idling valve 34, and in the other direction causes the stop 29 to engage the lever 20 and load the spring 22. The valve 4 mav be fitted in the intake of the supercharger. The lever 27 is mounted on a spindle 40 carrying a lever 41 having abut. ments 42, 43 between which is arranged the abutment 44 upon lever 45 connected to the valve 4. The arrangement is such that when the valve 4 is closing to reduce the supply of mixture, engagement between the abutments 43, 44 opens the valve 49 and causes a flow of air through pipes 38, 39 to the jet 3 resulting in a weakening of the mixture. The handle 20 may be connected to apparatus for supplying different kinds of fuels. Specification 431,293, [Group XXVI], is referred to.

A method of making ferrous articles, particularly blades for axial flow compressors and the like, by powder metallurgy comprises briquetting a mixture of iron powder and carbon into a self-sustaining mass having a density not more than 100 grams per cubic inch, pre-sintering the mass under non-oxidising conditions at a temperature less than that necessary for appreciable carbon diffusion, sizing the mass to increase its density to at least 105 grams per cubic inch, and sintering it in a controlled atmosphere at a temperature above the carbon diffusion temperature. Sponge iron powder, or iron powder produced from reduced iron oxide of 100 to 150 mesh size is mixed with up to 2.25 per cent graphite and briquetted at a pressure of from 30,000 to 60,000 lb. per square inch to a size slightly larger than the desired finished article and of a density between 90 and 100 grams per cubic inch. The article is then pre-sintered in a non-oxidizing atmosphere at a temperature of from 1600‹ to 1700‹ F. for about thirty minutes. The sizing is then performed in a die, whilst the article is hot or cold, at a pressure of from 60,000 to 150,000 lb. per square inch which brings the article to its exact shape and its density to between 105 and 122 grams per cubic inch. Finally the article is sintered at a temperature of from 1900‹ to 2050‹ F. for twenty to forty-five minutes. The article may be infiltrated or impregnated with a cuprous metal during or after the final sintering and in this case the density after sizing should not exceed 113 grams per cubic inch; sizing pressures of 60,000 to 90,000 lb. per square inch are suitable. Alloying ingredients such as nickel, chromium or manganese may be added to the iron-carbon mixture as separate metal powders, or the iron powder may be of a prealloyed type wherein the alloying ingredients are associated with each particle. The iron comprises at least 85 per cent by weight of the finished article and the carbon 0.4 to 1.0 per cent. The article may be heat-treated.
