Title: Process for modifying glass and other materials
Inventor: BOFFE MAURICE
IPC: C03C21/00
Filed: 1968-01-15
Abstract: 1,215,624. Chemical tempering. GLAVEKBEL. 15 Jan., 1968 [27 April, 1967], No. 2167/68. Heading C1M. A physical and/or chemical property of glass or vitrocrystalline material is modified by a diffusion of ions, into such material, in exchange for other ions, at least at one surface of the material from a bath of liquid medium, while such surface is in contact with or adjacent to a screen or wall which shelters a quantity or quantities of liquid medium in contact with the surface from haphazard disturbance by random currents in the bath. The chemical tempering process particularly involves an exchange of alkali metal ions. If a glass sheet being treated is vertical then steady vertical currents occur in the liquid medium which are undisturbed by lateral currents and the concentration gradient can be predetermined. The steady currents can be strengthened by pumping or by superimposing thermal convection currents, or for descending currents by a cooling action. A perforate or porous screen, e.g. a refractory fabric, may be used as the wall. An imperforate screen, e.g. a corrugated wall or a wall shaped to define with the article surface a distribution of pockets holding quanta of liquid medium may also be used. Diffusion may be increased by superimposing an electric field. A glass sheet may be chemically toughened differentially by using a perforated or apertured wall in contact with the article surface. Powdered carbon and silica can be added to the treatment bath to raise its viscosity, as well as glasses, e.g. borosilicate glasses, preferably potassium glasses, zeolites, montmorillonites, bentonites, kaolins, micas such as muscovite, biotite, leucite, kaliophylite and microline, silica gels, glauconite and phlogopite. The substance added to increase the viscosity can also serve as an ion-exchange material which absorbs ions coming from the article and releases further quantities of ions which are to be introduced into such material, e.g. montmorillonites and bentonites enriched with potassium or other ions.

Title: Improvements in internal combustion engines of the liquid fuel injection type
IPC: F02M69/00
Filed: 1932-01-25
Abstract: 394,048. Oil engines. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Jan. 25, 1932, No. 2228. Convention date, Jan. 26, 1931. [Classes 7 (ii) and 7 (iii).] Part of the liquid fuel delivered by a nozzle 20 is directed over the surface of of an air inlet valve 9, whilst another part is directed towards a sparking-plug 14. The valve 9 and an exhaust valve 13 are situated in the walls of a frusto conical combustion chamber. As shown in Fig. 1, a sparking plug 14 is disposed in a recess between the valves 9, 13 and the part of the fuel which reaches the plug impinges first on the surface of the exhaust valve 13. The fuel nozzle traverses the water jacket of the cylinder and contains a fluid pressure actuated valve 21<11> which opens outwardly into the cylinder. The fuel is supplied through a pipe 35 to flutings 26 which terminate in a passage 23 having an outlet 25 through which the fuel is sprayed towards the igniter. The amount of fuel passing through the nozzle and the ratio of the fuel issuing at the outlet 25 to that issuing past the valve 21<11> varies automatically with the engine speed. In a modified construction, all the fuel from the nozzle is directed towards the air inlet valve 9 and a deflector composed of high heatresisting material is disposed so as to deflect a part of the fuel into the recess housing the sparking plug. The deflector is maintained at a temperature between the vaporizing and igniting points of the fuel by heating it by a thermocouple or other thermostatic control or by varying the position of its attachment to the cylinder head. A charge of carburetted air may be introduced through the valve 9, and an igniter consisting of a series of hot surfaces may replace the sparking-plug.

Abstract: 1,270,641. Recording-apparatus. YORKSHIRE IMPERIAL METALS Ltd. Jan. 4, 1971 [Jan. 16, 1970], No.2247/70. Heading G1J. Recording-apparatus comprises a stylus 6 supplied with self-quenching alternating current at a frequency of 10 kHz and with a peak voltage sufficiently high to produce a trace on electrically sensitive paper. A typical paper requires a supply between 400 and 500 volts at a preferred frequency of 35 kHz and the stylus may have a point of mild steel, stainless steel, tungsten, molybdenum tungsten or tungsten carbide. As shown in Fig. 2 a ten-volt battery 9 is connected in series with an inductor 10 connected to the mid-point 11 of the primary winding 12 of a transformer 13. The ends of the winding 12 (e.g. of 8 turns) are connected through diodes 14 with the collectors 15 of transistors 16 with earthed emitters 17, the collector 15 of each being connected through a resistance 19 to the base 20 of the other transistor 16. The secondary winding (e.g. of 80 turns) is connected across the stylus point 6 and a base 24 over which electrically sensitive paper travels with an adjustable capacitor 23 in series. Each pulse produces a trace of length approximately equal to the thickness of the stylus and the frequency is sufficient to ensure overlapping to give the appearance of a continuous trace.

Abstract: 524,122. Ship's draught &c. indicators. KING, B. W. Jan. 23, 1939, No. 2284. Convention date, July 29, 1938. [Class 113 (i)] A manually operated portable water level indicating instrument adapted to be lowered into the water adjacent a ship for determining its draught, comprises a vented water chamber containing a float which actuates an indicator on the water chamber and visible from above, and a flexible elongated tube having one end attached to an inlet on the water chamber and the other end adapted to be submerged a substantial distance below the surface of the water so that the level of the water inside the chamber may be brought to the mean level of the outside water regardless of surface fluctuations. In the form shown, the indicator comprises a body 20 forming a water chamber 23 which is fitted at the top with a transparent arcuate cap 24 and with a boss 26 which receives a pipe 27 with a vent 28, the pipe 27 being attached to a chain 48 with an attaching device 49 at a predetermined distance from the top of horizontal flanges 47 on the body 20 at the same level as the axis of a cylindrical float 40. At the bottom the body 20 is fitted with a boss 33 which receives a shell 38 for the connection of a long flexible tube 50 with a weighted perforated metal intake nozzle 51. The shell 38 carries a float 36 for a check valve 35, and vents 39 communicate with the top of the chamber 23. The rear of the body 20 is formed with an opening 31 with a water glass 30 and graduations 32. The float 40 is eccentrically pivoted inside the chamber 23 and carries a light tangential arm 42 bent to form a vane 43 which moves beneath the cap 24 and above a thin arcuate wall 44. An arm 45 is pivoted on the pivot of the float 40 and is bent inwardly at 46 to form a manually movable water density indicator. A tape measure 53 is secured to the attaching device 49 and run through a square tube 60 surrounded by a casing 62, formed with a foot piece 61, and carrying a handle 68 with a wrist chain 69. The indicator is moved up and down until the top of the flanges 47 appear to be level with the mean water level A-B, and when the vane 43 is in line with the indicator 46, the water level a-b in the chamber 23 corresponds to the water level A-B. The reading on the tape 53 then enables the desired vertical measurements to be completed. If the device is lifted rapidly, the valve 35 is closed and the height of the water trapped in the chamber 23 can be checked by the graduations 32. In one modification the cylindrical float 40 nearly fills the chamber 23, whilst in another the device is moved up and down a graduated rod having an arm to engage the bottom of the ship.

Abstract: 669,221. Sliding windows and doors. BEATON & SON, Ltd., G., and YOUNG, F. C. June 28, 1950 [Jan. 30, 1950; Feb. 9,1950] Nos. 2356/50 and 3410/50. Class 20(iii) [Also in Group XXV] Sliding window or door mechanism, particularly suitable for full-drop or half-drop vehicle windows, have opposed outwardly projecting rollers 3, 4 on opposite margins of the window engaging by spring-operated means relatively inclined guides 5, 6 on corresponding sides of the frame ; one guide 5 is parallel with the direction of movement of the window and its roller 3 is fixed relatively to the window, the other roller 4 riding on the inclined guide 6 being displaceable. Its bracket 8 is carried by a yoke 9 to which are connected dual plungers 10, 11 slidably mounted in tubes 12,13 on the base of the window panel, the roller being urged against the guide by springs 14, 15 the tension of which is adjustable by movement of stops 20, 21 on guide rods 16a, 17a. To prevent ejection of the plungers when the window is removed, outward movement of the yoke is limited by engagement of a pin on a rod 24 with an abutment 25. A pair of rollers may be provided at both the upper and lower edges of a window and the inclined guides for the two displaceable rollers may be on opposite sides of the frame. The spring plungers may comprise solid cylinders with longitudinal and circumferential grooves such that a pin projecting inwardly from the plunger housing is normally accommodated in the longitudinal groove, the inner closed end of which by abutment against the pin prevents ejection of the plunger, but by rotation of the plunger through 180 degrees the pin passes along the circumferential groove into an openended slot so pressing the plunger. The plungers may be retained fully within their housings by means of a locking pin inserted through holes in the housing. An auxiliary operating mechanism comprises a toothed rack 70 and pinion 71 on a shaft 72 rotated by a crank handle 74. The mechanism, which is preferably applied at the side of the window adjacent the guide parallel to the window movement, is of coarse mesh, permitting full extent of movement by a few turns only of the crank. To disengage the pinion for removal of the window shaft 72 may be slid inwardly, a spring-pressed retaining ball 75 normally seated in a groove 72a being thereby displaced. The lower fixed pane 31 may be removed with its rubber glazing moulding 60 by springing the outer edge 60a of the moulding over a ridge 64 upstanding from the window pane. A horizontally sliding window assembly may comprise a panel sliding into overlapping relationship with a fixed panel and biassed either towards the open or the closed position.

Abstract: 284,857. King, C. F. L. Jan. 27, 1927. Centrifugal governors; transmitting-mechanism. -The speed of a motor vehicle is prevented from exceeding a predetermined limit by a governor driven from the engine or from the road wheels of the vehicle, and adapted to actuate suddenly a fuel valve coacting with the diffuser tube or nozzle of the carburettor when the predetermined 'speed is reached. The governor is housed in a casing 1 mounted above the carburettor and comprises weights 7 pivoted to a member 8 fixed to the driving shaft 9, and connected by arms 7a and links 11 to a sleeve 12 slidable on the shaft 9. The movement of the sleeve 12 is transmitted to a fuel valve 5 coacting with the nozzle aperture or with a seat 6 at the bottom of the diffuser tube 4 of the carburettor, through a lever IS pivoted at 19 to the casing 1 and provided at the upper end with a roller 16 engaging a groove 15 on the sleeve 12, an arm 25 provided with a downwardly projecting tooth 27 and pivoted at 26 to a projection on the lever 18, and a lever 21 provided with an upwardly projecting tooth 24 and mounted on a pivot 20 vertically above the pivot 19. One end of the lever 21 bears upon the top of the fuel valve 5 which is normally held open by a spring 22, and the free end of the arm 25 is attached by a spring 28 to a lug at the lower end of the lever 18. The tooth 24 is situated vertically above the pivot 20, and under normal running conditions engages the lower edge of the arm 25, whilst the tooth 27 is raised slightly above the edge of the lever 21, as shown in the Figure, so that the force of the spring 28 acts upon the lever 21 at a point vertically above the pivot 20, with the result that the valve 5 is held open by the spring 22. When the governor is actuated, the axial movement of the sleeve 12 is transmitted through the lever 18 to the tooth 27 which rides up the tooth 24, and when the predetermined speed is reached, the tooth 27 passes over the apex of the tooth 24 whereupon the spring 28 immediately moves the arm 25 downwards thus operating the lever 21 and closing the valve 5. In modifications (1) the lever 21 is mounted upon the pivot 19 and is operated by a spring-loaded catch which is pivoted on the lever 18 and engages the tooth 24, (2) the lever 18 is replaced by a toggle lever, the outer ends of which are connected by a spring and the lower member of which is provided with a lug coacting with the lower edge of the lever 21, the arm 25 and the. tooth 24 being dispensed with.

Title: Improvements in electrical devices, such as variable electrostatic condensers, variable resistances and the like
Filed: 1923-01-27
Abstract: 214,734. Dubilier, W. Jan. 27, 1923. Variable resistances.-An electric device such as a variable condenser, resistance or the like, comprises a pair of members, the relative position of which determines the electrical characteristics of the device, a third member adapted progressively to be introduced and withdrawn from between the pair of members to cause their relative displacement, and means acting in the opposite sense to the third member for restoring the pair of members to their original positions after displacement. When applied to a variable condenser, one of the pair of members comprises a fixed armature A covered by a dielectric layer B, Figs. 7 and 8, and mounted in a recess 7 in the bottom of a casing 1. The other armature 3 is in the form of a split ring of flexible material, one end of which is secured to the casing in contact with the dielectric sheet B, while the other end passes through a slot 9 in a rotatable disc 6. The slot 9 is V-shaped, and its side walls are chamfered, as shown at 10, to form a wedge. On rotating the disc in one direction, the member 3 passes through the slot into the position shown in Fig. 2, thereby reducing the capacity to a minimum; rotation in the opposite direction causes the opposite edge of the slot to engage the armature and replace it on the surface of the dielectric B with progressive increase of capacity. The disc 6 is resiliently secured to an enlarged head of a spindle 14 by means of a pair of strip springs which are mounted in grooves or recesses 15 in the disc and in grooves in the head of the spindle and secured to the latter by a screw 19. These springs serve to exert pressure, which can be adjusted by means of the screw 19, between the portion of the armature 3 which is beneath the disc and the dielectric. The disc is prevented from frictional contact with the dielectric, when the greater part of the armature 3 has passed outside the disc, by shoulders 8 on the casing 1. In applying the invention to a variable grid leak or other resistance, the dielectric sheet is omitted, and the resistance of the member A is varied by short-circuiting portions of t by means of the member 3. The member 3 may be of volute form, and the wedge device fcr separating it from the fixed member may move in a spiral path.
