Abstract: 1,084,482. Manipulating filter tips. VAUTIER FRERES & CIE S.A. Feb. 7, 1966 [Feb. 25, 1965], No. 5366/66. Heading A2C. A machine for inserting filter tips 2<SP>1</SP> into mouthpieces 23 for attachment to cigars comprises three vertically arranged cylinders 1, 21, 22, each having six cavities and revolving intermently on axes parallel but offset, in the first cylinder 1 of which filter cores are cut to the required size, and in the third cylinder 22 of which they are inserted into mouthpieces 23. The filter cores are fed from a hopper 3 to a spout 14 and then into a cavity at position f of the cylinder 1. A photocell 4 determines, when the cavity is in position a, whether it is empty or not. If it is, a valve 6 is opened to allow pressure to pass from a pipe 7 to cylinders 11 and 9, the cylinder 11 serving to eject a filter core from the hopper 3 into the spout 14, and the piston 13 of the cylinder 9 holds the core 2 in position until the light to the cell 4 is cut off. The valve 6 is then closed, the pistons of cylinders 9 and 11 retracted and the core dropped into a cavity at position f. At position d a tip 2<SP>1</SP> is cut from the core by a knife 19. Should a core fail to be present in the cavity at previous position e this is detected by a photocell 18 which energizes a clutch E to stop the machine. At position c the cut tip falls into a cavity in the second cylinder 21 which supplies it to a cavity in the third cylinder 22 which is already being supplied with a mouthpiece 23 from a supply 24. Failure of the supply of mouthpieces is detected by a further photocell 26. A cam 31 rotates in timed relationship with the cylinder 22 and, when the filter tip 2<SP>1</SP> is in axial correspondence with the mouthpiece 23, energizes an electro-valve 33 to allow pressure into a cylinder 28, the piston 30 of which is thereby operated to drive the tip 2<SP>1</SP> into the mouthpiece 23.

Title: Improvements in the production of ferrites
IPC: C04B35/26
Filed: 1952-03-05
Abstract: Ferrites having magnetic properties suitable for coil cores are produced by acting on the metals (the oxides of which form the ferrites) in suitable proportions with oxygen at the melting temperature, the heat necessary for melting the metals being supplied by the oxidation process itself.  In a modification, only part of the metal constituent of the ferrites advantageously iron, is supplied in metallic form the remainder being supplied as oxide or carbonate, e.g. zinc oxide, pyrolusite.  The metals to be melted wholly or in part, are preferably employed in comminuted form.  The resulting oxides may be kept liquid at the end of the process by external, e.g. arc or resistance, heating.  The melt is cooled, preferably in a current of oxygen, if desired whilst pouring into moulds.  The solidified product may alternatively be pulverized, and cores pressed from the powder.  The pressed cores may be sintered in oxygen at 900-1300 DEG C., and quenched in water. Examples descibe the production of nickel-zinc, and nickel-zinc-manganese ferrites, and reference is made to lead-copper, manganese-zinc, copper-zinc, magnesium-zinc, and cobalt ferrites.  According to the examples, the charge is ignited by a short contact with a naked flame.

Title: Improvements in pneumatically-actuated devices for controlling, indicating or recording a variable condition
IPC: G01D5/42
Filed: 1952-03-06
Abstract: 700,441. Fluid-pressure servomotor control systems. FOXBORO CO. March 6, 1952 [March 14, 1951], No. 5891/52. Class 135 A pneumatically-actuated device for controlling, indicating, or recording a variable condition includes a nozzle-and-flapper valve wherein changes in the variable cause movement of the flapper, and the ensuing changes in the flow through the nozzle produce changes in pressure in the fluid supply, which changes, besides being available for control &c. purposes, are applied to the flapper by means of a ball-piston unit in opposition to the movements due to changes in the variable condition. In an embodiment, the temperature in a process tank 10, Fig. 1, is sensed by a bulb 11 which produces a corresponding pressure in a Bourdon tube 13. Movement of the latter due to a change in temperature acts through a link 14 to pivot a T-lever 16 about its fulcrum 17, and an abutment 18 on the lever will cause, or allow, a composite frame 19, 20 to tilt about its pivoting axis 24. This composite frame comprises a trident 19 with its centre limb 19a capable of flexing and a superposed triangle 20 with its apex carrying a screwed abutment 23 by which the tension on the limb 19a can be adjusted. Limb 19a constitutes the flapper controlling the flow of air from a nozzle 26, the latter being connected through a chamber 31 and a restriction 32 to a supply 29 of air under pressure. The varying pressure produced in chamber 31 due to movements of flapper 19a acts on a diaphragm 33 which actuates inlet and exhaust valves 35 to control the connection of a chamber 34 to the supply 29 or to exhaust at 38. Valve 35 is loaded by a spring 36. Chamber 34, besides being connected to a motor-actuated valve 41 which controls the flow of heating or cooling medium to tank 10, is also connected to a cylinder 27 containing a piston 45, Fig. 2, in the shape of a ball, the latter being in contact with flapper 19a and serving to neutralize the latter after a controlling movement thereof due to a change in the temperature in tank 10. The amplification produced by the unit can be varied by adjusting the position of the nozzle along the length of the flapper by means of a slide 43, and when the nozzle is positioned immediately under the base of frame 19, the device becomes a simple " onoff " unit. Specification 670,419 is referred to.

Abstract: 213,870. Monier, F. Nov. 5, 1921, [Convention date]. Addition to 188,636. Spray carburettors. - The delivery of fuel from an orifice 14 at the constriction of the choke tube, as described in the parent Specificafion, is regulated by a tube from the air space of the float chamber which terminates either at a point 59 situated in the convergent part at a distance D/# from the constriction, or at a point 60 in the divergent part at a distance 2.D from the constriction, where D is the diameter of the constriction, or at both these points. A further larger tube 62 having a cock 63 with a wedge-shaped part may connect an annular chamber 16 behind the fuel orifice 14 with the air-space of the float chamber. The fuel nozzle 8 may be either radial or tangential with respect to the chamber 16. The sole throttle 19 is between the air inlet and the constriction; it is cone-shaped and has grooves 28 so that, when it is slid on a rod 42 by a lever 22, passages are left for the slow-running mixture. Passages 17 leading to the annular chamber 16 are closed by a cone-shaped member 26 which is held by a spring 27 against a collar on the stem of the throttle 19 so that the passages 17 are not opened for an inrush of air until the throttle has been lowered a small amount. Alternately, a cam on the shaft 21 of the lever 22 may open a needle valve and so admit air to the chamber 16.
