Title: Improvements in the manufacture of scraper piston rings
IPC: F02F5/00
Filed: 1941-11-26
Abstract: 548,821. Making piston rings. BAILEY, R. W. H. Nov. 26, 1941, No. 15228. [Class 83 (ii)] A scraper piston ring is made by forming a solid ring A, Fig. 3, having a greater radial thickness towards one face, the extra metal B<SP>1</SP> being carried on the inside, splitting the ring, expanding it sufficiently to obtain ultimately the desired free gap, stabilizing it, and holding it contracted while the metal B<SP>1</SP> is removed. The ring becomes twisted by expanding, e.g. on a mandrel, and after stabilizing the ring by heating it to 500 to 6000 C. anc allowing it to cool, this twist, shown exaggerated in Fig. 2, remains as a permanent set while the ring is contracted, by inserting in a cylinder C, clamped b) known means C<SP>1</SP>, and machined to remove the metal B<SP>1</SP>. In a modification the expansion anc stabilization is effected by hammering or knurling the inner face of the ring. The extra metal may have a rectangular section B2, Fig 7, or the outer surface of the ring have a groove D or both.

Title: Ionization fire alarm
IPC: G08B17/11
Filed: 1971-05-17
Abstract: 1329475 Ionization fire detectors PREUSSAG AG FELIERSCHUTZ 17 May 1971 [ 16 May 1970 30 April 1971] 15285/71 Heading GIN In an ionization fire detector including a radioactive source the source has an activity less than 0À1 microcuries so that both free ions from smokeless fires which cause an increase in ionization current and smoke colloidal particles which cause decrease in ionization current can be detected. In the arrangement of Fig. 2 the junction of measuring chamber 1 and reference chamber 2 including radioactive sources 30, 31 is connected to output terminals 11, 12 via F.E.T. amplifiers 44, 43, dividers 5, 6 and 7, 8 being adjusted so that there is a voltage at 12 but not at 11. In the case of a smokeless fire the ionization current in chamber 1 is increased and the voltage at 12 becomes zero to operate an alarm. If smoke colloidal particles enter chamber 1 the ionization current decreases and the voltage at 11 increases to operate an alarm. Terminal 11 may be omitted and dividers 5, 6 adjusted so that both an increase or decrease in ionization current can be indicated at 12, Fig. 1 (not shown). The junction of the chambers 1, 2 may be connected to one input of an F.E.T. differential amplifier Fig. 4 (not shown). To produce a fire alarm signal only when the  rate of charge of ionization current in chamber 1 exceeds a threshold level i.e. prevent the alarm being triggered due to DUST ACCUMULATION in the chamber the output of a F.E.T. connected to the chamber 1 is connected to a threshold amplifer via a differentiating amplifier. Alternatively or in addition an operational amplifier having a predetermined threshold may be used to actuate an alarm when the DUST ACCUMULATION exceeds a predetermined level, Figs. 5, 6, 7, 8 (not shown). DUST ACCUMULATION may also be detected by monitoring the activity of the radio-active source by means of a radiation detector and using the output of the detector to activate an alarm when the activity falls below a predetermined level, Fig. 9 (not shown) or to vary the conductivity of a transistor in series with the measuring chamber in place of the reference chamber 2 to nullify the effects of dust accumulation Instead of using a radiation detector DUST ACCUMULATION may be detected by insulating the radio-active source from the outer electrode so that a leakage current flows across the insulation when dust accumulates thereon which current may be used to operate an alarm or mitigate the effect of the dust Figs. 11, 12 (not shown). In Fig.13 (not shown) an auxiliary annular inner electrode is provided so that in the quiescent state these two electrodes are at equal potential and the ionization currents are equal. A fire alarm signal is only produced if there is a difference between the two currents.

Title: Improvements in and relating to overspeed safety devices for ignition devices for internal combustion engines
IPC: F02P9/00
Filed: 1953-06-04
Abstract: 727,951. Engine stop-gear. SCINTILLA, Ltd. June 4, 1953 [June 4, 1952], No. 15440/53. Class 122 (4). [Also in Group XXXVII] The magneto of the ignition system of an internal-combustion engine is fitted with an overspeed device comprising a centrifugal governor which limits the top speed of the engine by earthing the high-tension current before it reaches the distributer system and also actuates a switch connected in parallel with the make-and-break contacts of the magneto to thereby short-circuit the primary current and stop the engine. The centrifugal governor is in the form of a bell-crank lever pivoted on a pin 7 held by a carrier 12 attached to the make- and-break cam 3 and comprising a long arm 61 and a short arm 6<SP>11</SP> carrying a flyweight 8, whose centrifugal action on the bell-crank is opposed by a spring 9, and a projecting boss 6<SP>111</SP> normally clear of a radial wing 18 on an eccentric switch 16 fixed on the inner end of a shaft 15 that extends through a bearing member 13 into the magneto housing 1. A contact spring 20 electrically connected by a cable 21 to the circuit-breaking lever, extends from an insulated stop 19 on the member 13 and normally contacts a second insulator stop 131. When the engine attains its maximum permissible speed the long arm 61 of the governor is near enough to the distributer arm electrode 5 to permit the high-tension current to jump the gap and flow to earth and the boss 6<SP>111</SP> hits the radial wing 18 and the switch 16 turns into the position shown in Fig. 3 to contact the spring 20 and short-circuit the primary circuit. The switch can be operated by hand and reset in its inoperative position by a knob 17 attached to the shaft 15 outside the magneto housing.

Filed: 1968-04-01
Abstract: 1,193,585. Self-regulating PTC resistors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 April, 1968 [4 April, 1967], No. 15537/68. Heading H5H. [Also in Division H1] A PTC resistor of barium-lead titanate having a resistance that increases by ten-fold at a temperature of approximately 340‹ C. is mounted in plate form 1 in a soldering-iron having copper walls 6 and a copper soldering tip 7. Current applied to metal foils 2,3 flows through resistance 1 in the direction i, foils 2, 3 being insulated from walls 6 by mica foils 4, 5. When not used for soldering, the operating temperature is 350-360‹ C. This temperature prevails throughout the plate and the current remains small. During soldering, below 340‹ C., heat is emitted from tip 7 at W and thus a temperature gradient occurs along walls 6 and plate 1, the coldest area being adjacent tip 7. At the hottest end (right), a small current flows and substantially no more heat is produced. If a large quantity of heat is required the low temperature zone is enlarged further to the right and the development of heat automatically matches the need for heat. In a modification (Fig. 2), tip 7 is joined to a thermally conducting central plate (8), several plate-form resistances 1 being provided on either side of plate (8).

Abstract: 787,811. Copy grinding. FISCHER AKT.-GES., G. May 31, 1955 [May 31, 1954], No. 15671/55. Class 60. [Also in Group XXII] A machine for copying turbine &c. blades comprises one or more continuously rotated templets rotating about axes parallel to that of a workholder which is oscillated in timed relation to the templets, a tool holder or holders adapted to carry a grinding wheel being arranged to swivel about an axis or axes at right angles to that of the workpiece, the movements of which are controlled partly by the templets and partly by feed screws. A blade 12, Figs. 4 and 5, to be shaped is held between oscillatory members 47, 49, Fig. 4, which are both driven from an electric motor 64 through a gearbox 3 and crank 38 (only the drive to the upper member is shown). The crankpin 41, Fig. 6, drives a slide block 39 which moves between guides 44 in a slide plate 43 and thus reciprocates the latter. A rack 45 secured to the underside of this plate engages a pinion 46 on the shaft carrying the member 47. Gear wheels 5, 8, Fig. 4, secured to the crankshaft, rotates gear 6, 9 respectively on shafts 7, 10, carrying drum-like templets 11, 13. These templets have cut-control surfaces 11a over onehalf the periphery and tool-relief surfaces 11b over the other half. One or more tool-holders may be provided and these comprise frames 18, Fig. 5, pivoted about axes 16, 17, transverse to the work axis. The tools 20 are carried by slides 19 in the frames and springs 21, and levers 28, 23 maintain follower rolls 25 on the slides in contact with the templets. Blocks 32 sliding on guides 33 and fed by screws 34 carry rollers 31 which engage slots in the undersides of the tool slides 19 and thus pivot the tool frames about the axes 16 &c. to traverse the tools along the work. The screws may be rotated at a faster speed to provide a quick return controlled by stop mechanism (not described). Other known means, e.g., hydraulic or pneumatic, may be provided for causing the rolls 25 to follow the templets. Grinding wheels driven by means not described may be used in lieu of the tools 20.

Abstract: 401,218. Microscopes. ZEISS, C., [Firm of], Carl-Zeiss-Strasse, Jena, Germany. May 31, 1933, No. 15682. Convention date, June 4, 1932. [Class 97 (i).] A diaphragm system for microscope condensers comprises two reversely-disposed sets of substantially equal reflecting members each composed of a solid and hollow conical reflector. Central or marginal restriction of the aperture is obtained by suitably dimensioning the apex angle and diameter, or positioning the different members. As shown, parallel light is directed through the objective a, b, by solid and hollow conical reflectors c, d, e f. The reflectors c, d are adjustable axially by racks g, h and pinions i, k. By moving the reflector d towards the light source, as shown, the aperture is restricted marginally. Movement of the reflector c towards the objective restricts the aperture centrally, as shown in Fig. 3. Modifications are described in which the reflectors c, d are moved simultaneously by a single pinion, either in the same or in opposite directions. The diaphragm effect may be altered by replacing members of the system by similar members of different apex angle.

Abstract: 1,220,297. Gas analysis: wind direction indicators. UNION CARBIDE CORP. April 2, 1968 [April 3, 1967], No.15907/68. Headings G1B and G1R. A system for measuring air pollution, particularly that from a chosen source comprises first and second pollution measuring instruments 44, 46 e.g. filters which are electrically controlled to be either in a collecting or a non-collecting state, a rotatably mounted wind direction sensor 12 which aligns itself with the prevaling wind, and electrical contacts 24 which connect with a pointer 20 rotated by the sensor 12 to place the measuring instruments 44 or 46 in a collecting state only when the prevailing wind is in a direction leading from or to respectively the chosen source. The sensor 12 is preferably of white pine wood and is mounted on a rod 14 carried in bearings 13, 15. The pointer 20 is attached to the rod and is arranged to contact various ones of the contacts 24 depending on the prevailing wind direction. Certain adjacent contacts 24 may be shorted so that when the sensor 12 lies between two fixed angular valves a relay 30 will be energized and this will place the instrument 44 in its collecting state, the measuring instrument 46 being placed in the collecting state by a relay 32 when the wind direction is opposite to that for the instrument 44. By comparison of the amounts collected by the instruments 44, 46, the extra pollution caused by the chosen source over and above any other pollution can be determined. Each of the measuring instruments preferably comprises a fibre-glass filter and an air flowmeter, so that the pollution in micrograms per cubic metre can be determined from the quantity of dirt trapped by the filter divided by the average flow-rate through the filter.

Abstract: 792,439. Welding by fusion. AIR REDUCTION CO., Inc. May 23, 1956 [May 27, 1955], No. 15947/56. Class 83 (4). An electric arc-welding process consists in forming an arc between an electrode E and a workpiece W within a mass of solid carbon dioxide. Deoxidizing agents such as aluminium powder, alloying additions and arcstabilizing agents may be added to the solid carbon dioxide. Mild steel may be welded with a deoxidized steel wire using reverse polarity direct current. The process is applicable to the welding of stainless steel and aluminium. Non-consuming electrodes, such as carbon, may be used. For manual welding granular solid carbon dioxide is discharged from a hopper around the electrode but for mechanical welding the carbon dioxide is discharged in front of the electrode by a screw-feed from a hopper or by a device which granulates a solid mass of carbon dioxide. Alternatively, pressurized liquid carbon dioxide may be expanded to provide the solid form. Specification 791,459 is referred to.

Title: Improved method and apparatus for forming the tobacco rod in cigarette making machines
IPC: A24C5/18
Filed: 1928-06-02
Abstract: 291,467. Semenov, I. A. June 3, 1927, [Convention date]. Cigarette-making machines.-The. tobacco discharged from the carding roller a into the channel 3 of a machine of the continuous-rod type is subdivided by making the inclined back 2 of the shoot c in several sections of differing width, the largest section being at the middle. By this means the advancing band 4 receives successively quantities which correspond to the circular or oval cross-section of the completed rod. The diameter of the rod as thus formed is reduced by passage through channels 6, 11, 17 of decreasing diameter, each channel being partly conical and partly cylindrical. The belts 4, 10 moving within the channels 6, 11 compress the rod from opposite sides. Connecting members 7, 12 are grooved on one surface to guide the tobacco rod, but wedge-shaped on the other to batten out the bands 4, 10. Each channel is in two portions, a movable half, e.g. 6<b>, being hinged to a fixed half 6a by a pin 18. A doubly-toothed spring- pressed pawl 24 engages a projection 21 onthe part 6<b> and also a ratchet wheel 33. Abnormal working of the rod mechanism opens the channel halves, thus releasing the wheel 33, the rotation of which operates a signalling or stopping device. The cigarette paper is led in between the tobacco and the guide 17.
