Title: Improved method and apparatus for printing fabrics with metallization
IPC: D06Q1/10
Filed: 1951-12-19
Abstract: 712,437. Forming metallized signs &c. on fabric. LEBUY, P. Dec. 19, 1951 [Dec. 20, 1950], No. 29770/51. Class 100 (2). [Also in Group VIII] Metalized signs &c. are produced on fabrics by printing the signs &c. on the fabric by means of a driable composition and before the composition is dry submitting the printed side of the fabric to the action of an air jet in which metal particles have been suspended while air is caused to pass through the fabric from the non-printed side towards the printed side. In the apparatus shown in Fig. 1 for carrying out a continuous process the fabric 2 passes round a printing roller 3 associated with inking rollers 4 which distribute the driable viscous solution from trough 5, over the open side of a suction box 7, and over roller 8 to a drying apparatus. The suction box 7 is preferably inclined and connected at both ends by pipes 9 with a suction line 10 in turn connected with the suction side of an air pump or the like and including a centrifugal separator 11 and an air filter 12. A nozzle 13 passing through the bottom of box 7 and opening a small distance from the inner side of the fabric 2 is connected by a pipe 14 with the outlet from an air compressor, the pipe 14 including a venturi 15 the restricted portion of which is connected by pipe 16 with the bottom of a receptacle 17 containing metal powder, e.g. gold. The flow of the powder through pipe 16 is regulated by valve 18. The powder from nozzle 13 is retained on the printed portions of the fabric but falls back from the other portions and is removed by air flowing through the fabric under the action of suction line 10, the air flow through pipe 10 being greater than that through pipe 14. The excess powder is recovered at 11 and 12. The solution in trough 5 may comprise siccative oils or substances or may be formed of polymerisable substances, and in some cases may be non-viscous, retaining the powder by capillarity. The box 7 may be inclined in opposed direction to Fig. 1 with nozzle 13 at the leading edge and line 10 near the trailing edge, or the upper side of box 7 may be horizontal. Fig 4 shows a modification with two successive suction boxes 19, 20, box 19 containing the nozzle 13 and a line 10, and box 20 containing a line 10 only.

Title: Method for determining the cohesive strength of agglomerates
IPC: G01N15/08
Filed: 1968-06-24
Abstract: 1,203,687. Measuring cohesive strength. CENTRE NATIONAL DE RECHERCHES M•TALLURGIQUES. June 24, 1968 [July 3, 1967], No.29918/68. Heading G1S. A method of continuously determining the cohesive strength of agglomerated material such as sinter comprises continuously taking a sample of material which has been subjected to agglomeration treatment, subjecting the sample to attrition treatment during or after agglomeration and continuously measuring the permeability of the attrited material so obtained, the value of the permeability being a measure of the cohesive strength of the agglomerated material. As a result of the agglomeration process large agglomerates as well as attrited material or fines, i.e. small size particles, are produced and the permeability measurement is carried out on these fines which are normally returned to the agglomeration apparatus. If the attrition undergone in the agglomeration apparatus is not sufficient, the agglomerated material may be subjected to further attrition before passing to the apparatus for measuring the permeability of the attrited material. This apparatus comprises a hopper into which a sample of the attrited material is passed and a tube which blows air in the same direction as the flow of material. The variations in the rate of flow of the air are noted.

Filed: 1945-11-09
Abstract: 617,887. Electric welding; metal-working presses. SOC. ANON. DES USINES CHAUSSON. Nov. 9, 1945, No. 30005. Convention date, Nov. 23, 1944. [Class 83 (iv)] [Also in Group XXVIII] Hydraulically-controlled machine tools, particularly electric resistance welding machines, have the pressure in the hydraulic system applied by a plunger directly connected to an electromagnet. Application to riveting- machines is mentioned. Movable spot-welding electrodes 44 to 48 co-operate with fixed electrodes 49 in succession as determined by pressure in cylinders 43 admitted by valves 29 controlled by a cam-shaft 54 geared to a shaft 59 driven through a clutch 62 from a motor 64. The valves 29 make connection with a cylinder 2 having a plunger 3 directly connected to a rod 4 carrying the armature 5 of an electromagnet 8. A solenoid 16 retracts the armature after a pressure stroke. If the stroke of the plunger 3 increases, due to wear of the electrodes &c., excessive pressue due to near contact of the armature and magnet is avoided by an opposing spring 12 brought into action by contact of the parts 10, 11. The cycle is started by closing a switch 70, a solenoid 69 then rocks a lever 66 against a spring 67 allowing the spring 65 to close the clutch 62. A second cam-shaft 76 is driven from the shaft 59 and makes as many turns for one turn of the shaft 54 as there are electrodes 48. The cam-controlled switch 80 energizes the electromagnet 8 and causes an electrode to close on the work. Welding current is applied by the switch 81 and the welding circuit is broken by an automatic condenser switch (not shown). Opening of the switch 80 closes a switch for the solenoid 16. When all the electrodes have functioned, a cam 61 opens the clutch 62 and the machine stops. The work is then re-set for a further series of welds.

Filed: 1956-10-05
Abstract: 808,591. Calibration of local oscillators. COLLINS RADIO CO. Oct. 5, 1956 [Oct. 6, 1955], No. 30460/56. Class 37. The output frequency of the local oscillator 10 of a radio receiver is calibrated by comparing it with another precalibrated and preferably very similar oscillator 21. The oscillators are ganged together and are varied by means of knob 27. The standard oscillator 21 produces a frequency # 1  and the local oscillator 10 a frequency # 1  + ## 1 . A stable oscillator 28 produces a frequency f 2  which is the tuned frequency of the I.F. amplifier 18 mentioned below. This frequency # 2  is mixed with # 1  from 21 in mixer 29 to produce frequencies # 1 +# 2  and # 1 - # 2 . These frequencies are applied to a frequency preselector 12 which selects the appropriate frequency say # 1 +# 2  which is then fed into a mixer 14 together with frequency # 1 + ## 1  from 10. The result is a frequency f 2 - #f 1  (amongst other unwanted frequencies rejected by the tuned I.F. amplifier) which being within the correct frequency range is amplified by I.F. amplifier 18. The output is fed into a limiter and frequency discriminator 33 which gives a D.C. output proportional to #f 1  and which is indicated on meter 34. Ideally the relationship between angular displacement of the knob 27 and frequency f 1  should be linear but if this is not possible adjustment can be made to alter the frequency of 28 by cam means 36 in order to maintain the important frequency f 1 +f 2  in a linear relationship with the angular displacement of 27. Components 10, 12, 14 and 18 may be the components of an ordinary superheterodyne receiver.

Abstract: 784,408. Gas turbine jet propulsion engines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Oct. 10, 1955 [Oct. 22, 1954], No. 30505/54. Class 110 (3). [Also in Group XXXIII] A control system for an aircraft gas turbine engine in which propulsive thrust is developed by the turbine exhaust gases and also by an additional air flow accelerated by the engine, e.g. by a propeller or ducted fan, has mechanism responsive both to jet total head pressure ratio and ram air total head pressure ratio controlling a device to control the division of the engine useful power between the exhaust gas thrust and the acceleration of the additional air flow. In the arrangement shown, the turbine-propeller engine 7 has a variable pitch propeller 8 and a variable area jet nozzle 9. Ram air total head pressure is connected to a chamber 12 formed by a diaphragm 14 in a control box 13. Jet total head pressure is connected to a chamber 16 formed by a diaphragm 17. The diaphragms which are of unequal area, are connected by a link rod 19 to a servo-mechanism 21 which is connected to the variable pitch mechanism 10 and the jacks 24 of the variable area nozzle. The diaphragm areas are arranged so that if the ratio of the jet total head pressure to that of the ram air is at the predetermined optimum then the rod 19 is stationary. Variations from the optimum value actuate the servo-mechanism to restore this condition. If a constant speed propeller is used, the control system need only affect the variable area nozzle. The power taken by the propeller may be varied by varying the nozzle inlet guide blades to the propeller driving turbine. The invention may be applied to a bypass gas turbine engine in which the fan blade settings are controlled by the system together with a variable area nozzle. In a modification, the by-pass air flow is controlled by variation of the area of the by-pass duct. In a further modification, the nozzle guide vanes preceding the turbine stages driving the fan may be varied.
