Abstract: The method involves calculating the difference (RTD=R12-0, R12-1) between a first time reference of a first oscillator and a second time reference of a second oscillator at two successive instants (t0,t4). This is determined as a function of the propagation time difference associated with the first and second oscillators. The variation between the calculated reference time differences is determined by a time unit. The frequency difference between the oscillators is determined in response to a variation in the calculated time differences which is greater than a given threshold.

Abstract: 1,020,357. Froth flotation; agitating suspensions. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. April 7, 1964 [April 13, 1963], No. 14318/64. Headings B1C and B2H. A froth flotation cell comprises a perforated agitator plate 4 which is actuated by an electromagnetic vibrator 2 and of such configuration that it offers greater resistance to the passage of suspension therethrough in one direction than in the other, and discharge orifices 8 from air feed conduits 7, Figs. 2 and 3 (not shown), attached to the agitator plate on the side from which the resistance to the passage is greater. Such an agitator produces, in operation, zones of suspension at a pressure below the normal pressure. The agitator is formed of pressed steel plate having frusto-conical depressions 6, the bottoms of which are formed with apertures 15. Each air feed conduit 7 is welded to the underside of the agitator plate and arranged so that the orifices 8 are adjacent the apertures 15, the inner end of the conduit being in communication with a hollow supporting rod 3 which is supplied with compressed air through its inlet 3. When vibrated in its vertical direction, some of the suspension is passed out through an outlet 9 and a circulatory current is set up in the direction of the arrows 10; during this circulation, some of the suspension passes through the apertures 15 so as to produce a zone of reduced pressure around the orifices 8. The froth is removed by a paddle wheel 13. A series of cells may be grouped around a single vibrator, linkages connecting the agitators with the vibrator.

Title: Sulphonation of cross-linked vinylbenzene polymers
IPC: C08F8/34
Filed: 1961-01-11
Abstract: Sulphonated cross-linked vinyl-benzene polymers are treated with oleum between 50-120 DEG C. to increase the sulphonic acid content. Suitable monomers e.g. styrene, vinyl ethyl benzenes or vinyl xylenes, are co-polymerized with 1-20% by weight of divinyl-benzene or -toluene or trivinyl benzene. The resulting polymer is sulphonated with either chlorosulphonic acid or sulphuric acid to give a sulphonated polymer with 0.7-1 sulphonic acid groups per nucleus. This polymer is further sulphonated with 4-20 times its weight of oleum (containing 10-70% of free sulphur trioxide) giving a polymer with 1.2-2 sulphonic acid groups per nucleus and may be used as a cation-exchange resin. Sulphonated cross-linked vinylbenzene polymers containing 1.2-2 sulphonic acid groups per benzene nucleus measured on the basis of the ion-exchange capacity of the resin are also claimed per se. Specifications 577,707 and 894,391 are referred to.

Title: Improvements in or relating to loading devices for revolvers
IPC: F41A9/85
Filed: 1943-01-25
Abstract: 566,757. Revolver loaders. CAMPBELL, SIR M. Jan. 25, 1943, No. 1269. [Class 9 (i)] A device for charging the chambers of revolver cylinders comprises a spring-pressed platform 52 having seats provided thereon, between studs 54, for the cartridges 8. The platform has limited rotatability around a central post 30, the extent of which is controlled by a stud 58, below the platform, moving in a slot 34 in a fixed diaphragm 24. When stud 58 is at either end of the slot, cartridges may be placed on the seats, and the platform is then pressed slightly inwards against the spring 56 and then rotated to midposition in which the cartridge rims 9 are located under fixed lugs 12 on the casing 20 of the device and lugs 48 on a central sleeve 44 on the diaphragm 24. The pressure is then released and the spring 56 causes the cartridges to be gripped between the platform and the lugs. To charge a revolver cylinder, the gripped cartridges are pushed into the cylinder chambers until the studs 54 engage the end of the cylinder and press the platform rearwards. The device is then rotated to move the lugs 12, 48 away from the cartridge rims and permit its removal. The post 30 is carried by a spring-pressed disc 32 which has also a pin 38 projecting therefrom and a hole 59 which is entered by the stud 58 when the platform is in the mid-position. Before the platform can be rotated, the post 30 must be pressed inwards to move the pin 38 out of a locking hole 36 in the diaphragm, and the hole 59 away from the stud 58. A modified construction is described in which the platform is locked by a cross-pin on a spring-pressed axial plunger.

Title: Improvements relating to a furnace installation
IPC: C21D9/70
Filed: 1959-01-13
Abstract: 913,719. Recirculating combustion products. STEIN, ATKINSON STORDY Ltd. Jan. 13, 1959 [Jan. 13, 1958], No. 1313/59. Class 51 (1). A heat treatment furnace, such as a soaking pit, is heated by a burner 14 firing through a Venturi port 13 and flue gases escape through an outlet 19. A passage 26 feeds flue gases entrained by part of the combustion air delivered by a nozzle 25 to mix with the gases issuing from the burner 14 in the port 13. The total amount of air fed to the burner is controlled in accordance with the temperature of the furnace, and the fuel/air ratio is maintained by a control 40. A valve 24 in the line 36 supplying air to the entrainment nozzle 25 is controlled by the furnace temperature in the opposite sense to the main air supply valve so that the proportion of combustion air fed to passage 26 and hence the amount of flue gas recirculated varies inversely with the fuel and air supply to the burner 14. The ratio control 40 is adjusted by a device 30 in dependence on the furnace temperature, its deviation from the required value, the combustion air temperature and the air flow through the passage 26 so that as the proportion of the combustion air fed through passage 26 increases, the fuel/air ratio of the supplies to burner 14 increases, so that when the furnace is at its maximum temperature, the whole of the combustion air flows through passage 26 entraining combustion products, and the fuel flow to the burner 14 is a minimum, and when the furnace is cold the whole of the combustion air is fed to the burner 14 with the maximum amount of fuel. Instead of using a temperature-sensitive device to adjust the ratio control unit, a fuel line may by-pass the ratiocontrol operated valve, the fuel flow through the by-pass being controlled in accordance with the flow of air through the recirculation passage.

Title: Improvements in cone winders
IPC: B65H54/16
Filed: 1922-01-17
Abstract: 195,791. Campbell, W. E. Jan. 17,1922. Winding-machines.-In a cone winder the stepby-step gain movement is obtained by the rotation of a vertical screwed rod 21 which is carried by a bracket on the traverse rail and is engaged by a disengageable claw 44 on this 'bracket to cause its traverse. The rod 21 carries at its top end a non-rotatable arm adapted to slide on a guide post and a yarn guide 18. The rod 21 is rotated at every reciprocation of the traverse rail through a tappet rod 29, an adjustable screw 32 of which contacts with a plate 34 on the machine frame. The tappet rod rotates a helically slotted sleeve 26 which actuates a one-way clutch ring 36 which in turn causes rotation of a sleeve 23 splined to the rod 21. The sleeve 23 has a disengageable connection 37 with the clutch ring 36, engagement being maintained during normal working by the tension of the thread supporting a weighted guide arm 40, which drops on the thread breaking and slides the pins 37 out of engagement with the clutch ring and disengages the clutch teeth on the sleeve and ring.
