IPC: C04B18/04
Filed: 1992-04-14
Abstract: When sandblasting with glass sand, aluminium silicate and copper slag, the grains become worn down and fragmented, after which the used blasting material has previously been driven to a dump site; however, in the present case, I have instead found a use for this used blasting material as a filler additive within the asphalt and concrete industry and in brickworks. The possibilities of re-employing used blasting material results, on the one hand, in the expensive filler materials being saved for use in the asphalt and concrete industry and for replacing sand for admixing with clay in brickworks, and, on the other hand, in a contribution being made to society's endeavours to limit waste quantities, with this being combined with quantitative economies being made in the country's raw material resources.

Abstract: 1,005,456. Selective punching devices. ELECTRONIC MODULES (DESIGNS) Ltd. Nov. 10, 1964 [Jan. 2, 1964], No. 164/64. Heading B4B. A punching device comprises a driving member 1 and a punching member 2 between which is located a link member 3 having cam surfaces 3a engageable with a cam surface 2a on the member 2, the arrangement being such that when a control member 4 is in an inoperative position, Fig. 2, a camming action is permitted between the surfaces 2a, 3a so that a punching stroke of the member 1 causes relative movement between the member 3 and the member 2 without transmitting a drive to the member 2, but when the member 4 is in an operative position, Fig. 1, the camming action and relative movement between the member 3 and the member 2 is prevented, and a punching stroke of the member 1 is transmitted to the member 2 to cause punching to be effected. The member 3 is in the form of a U-shaped spring accommodated between opposed slots in the member 1 which is tubular. The member 4 forms the armature of an electromagnet 12. The upper end of the member 1 is secured to a driving plate 6. With the member 4 in the operative position, when the member 1 is thrust downwardly under the influence of the plate 6, a punch 7 is forced through a die 8 to perforate a card 9. Upon the return movement of the plate 6, the punch is lifted to its original position by means of a plate 10 connected to the plate 6, the member 2 being held down by a nut 13 co-operating with a return plate 11 connected to the die 8. When the electromagnet 12 is energized, the member 4 is drawn upwardly and when the plate 6 is thrust downwardly, the camming effect of the surfaces 2a, 3a is such as to thrust the free ends of the member 3 inwardly towards each other, Fig. 2, to permit the member 1 to move further into the member 2. The punching devices are included in an electric circuit, Fig. 3, each punching device being controlled by a buffer stage 24 when the stage receives an interrogating pulse from a sequence circuit 25, the buffer stages being controlled in turn by a binary counter 22 driven by a pulse generator 21.

Title: Improvements in aircraft propulsion power plants
Inventor: MARCHANT FRANCIS CHARLES IVOR
IPC: F02K1/00
Filed: 1963-01-02
Abstract: 1,069,431. Jet propelled aircraft. BRISTOL SIDDELEY ENGINES Ltd. Jan. 24, 1964 [Jan. 2, 1963; Feb. 28, 1963]. Nos. 275/63 and 8184/63. Heading B7G. An aircraft has a power plant comprising two turbo-jet engines abreast of one another and either side by side, as shown, or one over the other (Figs. 8-15, not shown) in a housing which may be the fuselage or a wing mounted pod. The power plant has a front pair 19 and a rear pair 20 of rotatable nozzles, the nozzles on one side receiving air from the compressor of one engine and exhaust gases from the other engine, and the nozzles on the other side receiving air from the compressor of the other engine and exhaust gases from the first engine. The rear nozzles 20 comprise elbow bends rotatable about axes 28 and the front nozzles may be similar (Fig. 6, not shown), and may be fitted with visors (36), or may depend below the housing and each have two sections (19a, 19b, Fig. 1. not shown) rotatable in opposite directions, Where the power plant is in the fuselage, nozzles are preferably arranged so that their longitudinal and transverse distances from the centre of gravity are inversely proportional to their thrust. Another method of reducing pitching and rolling moments in the event of the failure of one engine is to connect the compressor outlets of both engines to a downwardly directed nozzle (37, Fig. 7, not shown) operable by a valve (40). A flap valve (39) serves to isolate the compressor section of the failed engine. The engine exhausts may flow into a common duct (50) (Fig. 19, not shown) from which both rear nozzles (20) are fed, and interconnected flap valves (53, 54), which may be power operated isolate a failed engine and the rear nozzle on the opposite side, so that thrust is provided by a front nozzle on one side and a rear nozzle on the other. Each rear nozzle may include an annular duct supplied with air from the compressor of the engine that supplies exhaust gases to it (Figs. 8 and 9, not shown), and this air flow may be valve controlled for roll and pitch control. In another embodiment (Figs. 12-15, not shown), each of four nozzles has two concentric flow channels, through which each front nozzle is supplied with air from both engines, and each rear nozzle is supplied with exhaust gases from both engines. Alternatively, the ducts leading to the nozzles may be divided, and each nozzle provided with two or more diametral partitions. The air intakes to the engines are preferably arranged so that a horizontal plane passing through their centres passes between the centres of the front and rear nozzles. The front nozzles may be provided with reheat.

Title: Moisture gauging system
IPC: G01N23/12
Filed: 1965-01-04
Abstract: 1,092,956. Moisture content investigation using neutrons. REPUBLIC STEEL CORPORATION. Jan. 4, 1965 [Jan. 8, 1964], No. 341/65. Heading G1A. To determine the moisture content of a substance, which as described is sinter mix travelling along a conveyer, a source of fast neutrons and gamma rays is positioned to irradiate the substance. A slow neutron detector is provided to give an output dependant on the moisture content of the substance present in a monitored volume and a gamma detector to give a second output dependant on the mass of substance present, the two outputs being combined to produce a signal representative of the percentage water content of the substance. The device may be constructed as a C-shaped frame having a radium beryllium source at one extremity and two sets of parallel-connected detectors at the other. Boron trifluoride proportional counters are used as thermal neutron detectors and geiger tubes as gamma detectors. The C-frame is mounted for movement from a measuring position in which it encompasses a conveyer carrying sinter-mix to a withdrawn position in which calibration can be effected or corrected. A periodic recalibration cycle may be arranged to occur automatically in which the frame is withdrawn from the conveyer, zero and standard calibration samples inserted sequentially and the circuit recalibrated, and then the frame returned to its operative position. It is preferred to arrange the circuit so that electrical standards corresponding to normal moisture content and mass are used and only deviations from these standard values used to derive the final output. In such a system the device may check itself after each calibration to see if it gives a value within the expected range. If it does not do so a warning light is illuminated to indicate the need for a further calibration operation. The output of the device may control a device adding water to the mix in such a way as to keep the water content constant. Circuitry and constructional details are described.
Patent GB-782926-A (GB)
Title: Purification of polymyxin
Inventor: HASTINGS JOHN JAMES HUNTER
Filed: 1955-01-06
Abstract: Polymyxin is recovered from an aqueous liquid containing it by contacting the liquid with an ion exchange material which derives its exchange capacity from carboxyl groups, thereby adsorbing the polymyxin on to the said ionexchange material, eluting the polymyxin with an electrolyte, contacting the eluate with an ionexchange material A in order to remove anion impurities and with an ion exchange material B to remove cation impurities and then recovering the purified polymyxin thus produced.  The polymyxin solution is any aqueous solution containing it including a fermentation broth, the unfiltered broth being preferred since residual polymyxin retained in the bacterial cells is adsorbed.  The carboxyl ion-exchange material may be a copolymer of acrylic or methacrylic acid with divinyl benzene, e.g. Amberlite IRC50, Permutit H70 and Zeocarb 226, or a condensation product of formaldehyde and resorcyclic acid, e.g. Wofatit C.  The resin may be used in the free acid form or wholly or in part as a salt with a weakly basic cation such as ammonium. It is preferred to use the resin in the acid form and to add the weakly basic substance, e.g. aqueous ammonia, continuously or intermittently to the broth during adsorption to maintain the pH of the effluent between 6 and 7.  The preferred eluant is aqueous mineral acid, e.g. sulphuric or hydrochloric.  Material A is an anion exchange material having a basic nitrogen, especially modified phenol-formaldehyde polymers having amine groups or styrene polymers having quaternary amine groups, e.g. Amberlite IR4B and Amberlite IRA400, and is used in the hydroxyl form. Material B is a cationexchange material possessing strongly acidic groups, especially sulphonic acid groups, e.g. Amberlite IR120, which is a sulphonated styrene copolymer. Cations present as impurities are adsorbed while polymyxin is largely unadsorbed. A mixed bed of ion exchange materials A and B may be used.  The polymyxin is recovered from the purified solution by adjusting the pH to 3 to 4, preferably using ion exchange material A, concentrating, and adding alkali, e.g. aqueous ammonia, to pH above 7 in order to precipitate the polymyxin.  Heating to 70 DEG  C. facilitates precipitation.  The adsorption may be batch or continuous.  The continuous process is illustrated in the drawing (not shown) by equipment consisting of two columns of the carboxylic ion-exchange material and one of ion-exchange material B, a vessel for the eluant and a vessel for ion-exchange material A.  The micro-organism may be Bacillus polymyxa or B. aerosporus.  Reference has been directed by the Comptroller to Specification 742,589.

Abstract: 609,041. Valve amplifying circuits. PHILCO PRODUCTS, Inc. Jan. 8, 1946, No. 649. Convention date, Jan. 8, 1945. [Class 40 (vi)] An amplifier for television and other purposes requiring wide band-width and relatively high output voltage comprises a plurality of valves connected in series, anode to cathode. The input signal is applied to the grid of the first valve, the grids of the succeeding valves being connected to a point on the load system at which the signal amplitude is less than that at the corresponding cathode. The Figure shows an amplifier in which the signal is fed to control grid 61 of the first of three similar valves 62, 76 and 89. A point is chosen on section 69, 70 of the load system such that the alternating voltage across 69 is equal to the signal voltage applied to grid 61 and this point is connected to control grid 75 of the second valve 76. In a similar manner, point 85 is selected on the load and connected to the control grid 88 of the third valve 89. The output is taken from the anode of the third valve and ground. The output impedance is thus that of the valves in series and the input impedance that of the first valve only. The total gain is the gain of one stage multiplied by the number of valves. A common H.T. source 70<1> is shown, but in an alternative arrangement, Fig. 1 (not shown), separate H.T. and G.B. sources and separate load impedances are provided for each valve.
