Title: Gas filled trimmer capacitor
Filed: 1964-08-31
Abstract: 1,071,034. Capacitors. L. T. BARNES. Aug. 31, 1964, No. 35576/64. Heading H1M. A variable capacitor comprises a dielectric cylinder 16 of quartz, refractory glass, titania, or the like, formed with an external broad silver or like metal band 30 at one end and a similar narrow band 104 at the other end, by cementing or spraying and firing. A conductive end wall 12 is spigoted and cemented into one end of the cylinder, soldered to metal band 104, and formed centrally with borings to accommodate the slotted head 44 and threaded shank 38 of an insulating adjusting member of e.g. P.T.F.E. retained by split ring 52 in annular groove 22 over nylon washer 48. The shank engages a movable brass piston electrode 56 threaded at 68 to slide within the cylinder, and metal, e.g. copper bellows 70, is secured to the web 60 of the piston and to a contoured portion 76 of the rear of end-plate 12, while a metal bellows 80 is secured to the other side of web 60 and to an insulating, e.g. nylon end-plate 86 having an internally directed conical projection 88 and capable of fitting a depression 36 of endwall 14, which is of insulating material, e.g. P.T.F.E. The bellows are air filled or evacuated, and the space between them and the cylinder is filled with inert gas, e.g. nitrogen; the clearance around the piston permitting pressure equalization. Rotation of the adjusting member traverses the piston electrode along the interior of the cylinder to vary the capacitance between it and electrode 30, and thus between terminals 102 and 106; while extending and compressing bellows 70 which resists rotational movement of the piston and eliminates backlash. The end of the threaded portion bears on projection 88, whereby bellows 80 is similarly compressed and extended.

Title: Picture signal generating apparatus for colour television
IPC: H04N9/09
Filed: 1962-09-19
Abstract: 1,021,086. Colour television. HAZELTINEAGA LABORATORIUM G.m.b.H. Sept. 19, 1962 [Sept. 28, 1961], No. 35638/62. Heading H4F. In colour television signal generating apparatus employing pick-up devices F4, F5 and F6 responsive to the X, Y and Z primaries (Y corresponding to the spectral sensitivity of the human eye), a luminance signal Y is derived from the pick-up device F5 alone and the total light acting on the apparatus is divided among the pick-up devices so that the quantity acting on F5 is considerably larger than that acting on F4 or F6. By this means the signal-to-noise ratio of the signal which contributes the most annoying noise in the reproduced picture is improved. It is stated that in terms of signals of equal bandwidth the signal-to-noise ratio in the luminance channel should be at least 8 db. greater than that of the colour channels. The invention is described as applied to a system employing photo-electric cells in conjunction with a flying-spot scanner (not illustrated), the desired division of light being achieved by constructing device F5 with a sensitive surface area larger than that of devices F4 and F6. Alternatively the devices may comprise groups of cells, the number in group F5 being larger than the number in groups F4 and F6. Conventional signal mixing is effected by matrices M1, M2, and M3, and the individual signals are subjected to gamma correction. The colour difference signals are subjected to bandwidth restriction in filter BB; the luminance signal is subjected to an equalizing delay in unit V. The invention may be applied to colour cameras utilizing plural pick-up tubes or a single composite pick-up tube. A second embodiment, Fig. 3 (not shown), uses four pick-up devices (photo-electric cells or camera tubes), one for the luminance signal and three for red, green and blue component colour signals. The luminance signal used for forming the colour difference signals is derived from the component colour signals, thus the luminance pick-up device remains wholly independent. With this arrangement the exact form of luminance signal is not critical and it is sufficient if the luminance pick-up device is broadly sensitive to visible light and with a maximum sensitivity within the visible spectrum. As a consequence it is possible to utilize a device which does not require an associated light filter. The other three devices do require filters and this in itself is sufficient to achieve the desired light distribution between the devices.

Title: Improvements relating to rotary piston internal combustion engines
IPC: F02B53/00
Filed: 1962-09-19
Abstract: 1,022,433. Rotary-piston I.C. engines. F. STUMPFIG. Sept. 19, 1962, No. 35725/62. Heading F1F. In a rotary-piston I.C. engine atomized fuel e.g. petrol or oil, is injected into an evaporating chamber wherein it undergoes partial combustion before entering an associated working space situated between the piston and the casing, an evaporating chamber being provided for each working space. The engine may comprise an elliptical casing a (Figs. 1 2, not shown), a piston b of circular shape therein, radial vanes c slidably lodged in the piston, an air inlet f, an exhaust passage m, and and evaporating chamber e formed as an open channel, in the periphery of the piston between each pair of vanes into which fuel is periodically injected through a pipe or line o, the fuel being subsequntly ignited by a spark-plug k after the air drawn through inlet f has been compressed in an associated working chamber d. Products of combustion and unburnt fuel-air mixture are discharged from the evaporating chamber into the associated working chamber wherein combustion of the mixture is completed and the products of combustion are expanded before they are ejected through passage m. During induction and compression of the air in the associated working chamber fuel deposited on the hot walls of the evaporating chamber is vapourized, the vapourized fuel being urged toward the spark-plug by the compressed air as the chamber approaches the plug. The engine may be modified in that each evaporating chamber is in the form of an open-ended bore (Figs. 3, 4, not shown) which extends between each pair of vanes and receives atomized fuel from pipe o through a central transverse-bore q in the piston and an arcuate slot r formed in a side wall of the casing in register with the pipe. Alternatively, the engine may be of the trochoidal n and n + 1 lobe type (Figs. 5 to 14, not shown) wherein an evaporating chamber is formed in the periphery or a side face of the piston between each pair of apices, the chambers being in the form of open channels or bores. The spark-plug k may be lodged in an ignition chamber s (Figs. 5, 6) provided with a bore h through which products of combustion are ejected into the adjacent evaporating chamber. Pipe o may have its outlet end situated in a web member t (Figs. 11, 12) within the air inlet f, otherwise pipe o may have its outlet end situated in the casing adjacent inlet f. The evaporating chamber may receive fuel through a transverse bore q (Fig. 14) and an arcuate groove similar to groove r (Fig. 4). When the engine is started, the fuel may be vapourized externally of the casing and mixed with the air supplied to the engine. The products of combustion may undergo a second stage of expansion in a further rotary-piston engine. The working spaces may be scavenged by air being blown into them, and fuel may be injected into the evaporating chamber whilst the associated working space is being scavenged. The casing may be rotatable.

Title: Percussion fuze for projectiles
IPC: F42C15/32
Filed: 1937-12-28
Abstract: 508,309. Projectile fuzes. SAGEB SOC. ANON. DE GESTION ET D'EXPLOITATION DE BREVETS. Dec. 28, 1937, No. 35875. Convention date, Dec. 31, 1936. [Class 9 (i)] The safety device for the fuze of a rocketprojectile is held in the unarmed position by a locking member which is adapted to be depressed, to arm the fuze, by the deformation of a diaphragm forming one wall of the combustion chamber of the propulsive charge. The deformation of the diaphragm is effected by the pressure of the gases in the combustion chamber. In the construction shown, the diaphragm 16 bears against a locking cap 10 which is secured to a second cap 12 by means of a pin 11. When the cap 10 is depressed by the diaphragm, the pin is sheared and the cap moves into a position in which a throat 19 formed therein lies opposite a number of balls 17. The latter, which are normally held by the cap in the position shown, to lock the firing pin 13, are thus freed and move outwards under centrifugal force into the throat. On impact, the striker, hitherto held by means of a shearing pin 20 and a spring 15, is projected on to the primer 14.

Title: Speed change gear shifting device
IPC: B62M25/08
Filed: 1972-08-03
Abstract: 1395224 Change-speed control MARUISHI CYCLE INDUSTRIES Ltd 3 Aug 1972 36354/72 Heading F2D A gear shift lever 7 controlling, through a cable 8, five ratios of a pedal-cycle hub gear, is displaceable in steps for downshift only under control of an electrical circuit completed by a manual switch B, on the handle bar, and stationary printed contact strips 19, 20, 21, tracked by a brush 22 on the shift lever 7. Downshift displacement is effected by an electric motor 25 energized through the said circuit by a battery 32. The shift lever 7, on the cross-bar 4, can be moved in the upshift direction by direct manual operation only.  Secured to the shift lever 7 is a drum 13, 9 around which is wound an inner cable 8 controlling the hub gear, and a coil spring 14, acting as a self-tightening one-way clutch and brake between the drum 13 and a freely mounted gear-wheel 15, driven by the motor 25 through a worm-gear and two-stage spur reduction gear. Direct manual movement of the shift lever 7 in the downshift direction is prevented by tightening of the coil spring 14 on the shift lever drum 13, the spring being anchored at one end to the now stationary wheel 15. Upshift movement of the shift lever 7 is permitted by the spring 14 slackening on the drum 13 and slipping thereon. The manual switch B comprises two ganged switches 5a, 5b, controlling respectively motor start and stop circuits. A single depression of the switch button switches both 5a and 5b on, and the motor 25 drives the gear shift lever 7 through the coil spring 14, acting as a clutch, and drum 13 until the contact brush 22 rides off the start contact strip 20 on to the stop strip 19, thus stopping the motor. Release of the switch button switches off, and the motor is again energized, now through the stop strip 19 to make a further movement in the same direction on to the start strip 20, whereupon the motor circuit is again broken, the step terminated and ratio shift completed. Holding the switches closed continuously produces downshift through all the ratios to the lowest, when the stop strip 21 is contacted.

A rope or chain rupture safety device for a blowing lance secured to two lifting ropes 10, 11, comprises a driven main drum 3 over which the rope 10 passes, and an idling auxiliary drum 4 over which the rope 11 passes, the drum 4 being connected to the main drum 3 through an adjustable slip multiplate friction clutch 19 and being rotatable relative to the drum 3 in the event of rupture of the main rope 10 to progressively increase the engagement pressure of the clutch plates until the auxiliary rope 11 fully supports the blowing lance. The clutch 19 comprises interengaging friction plates 26 secured to a hub 20 of the driven drum shaft 16 and to a housing 23 secured to the auxiliary drum 4, the interengaging force between the plates being controlled by spring biased rams 28 mounted on a panel 30 screw threaded on to the hub 20 and locked by a tappet 33 for rotation with the auxiliary drum 4. Relative rotation between the drums causes the panel 30 to thread on to the hub 20 and through rams 28 to compress the clutch friction discs and eventually lock the drum 4 to the driven shaft 16. The free end of the rope 11 is secured to the blowing lance through a compression spring coupling incorporating a limit switch cam, whereby when either slack or tension develops in the rope 11 the drive motor for the main drum shaft 16 is braked. A stop is provided to limit the relative rotation between the two drums.

[Class 56] [See also Group X] A wall is lined with glass bars or plates 1 which are produced by a blowing process, and are each provided with integral flanges 2 running along two edges and so formed as to provide channel-shaped or undercut spaces 3 on the underside of the bar or plate for the reception of the fixing mortar 5. The spaces 3 may be provided by inwardly inclining the flanges 2 as shown in Fig. 1, or by forming the latter step-shaped as shown in Fig. 5. The upper edge of the plate may be formed with a stepped projection 7, Fig. 3, providing a recess for the adjacent upper plate and also a recess 8 below the projection for engaging with the fixing mortar. The outer face of the plate may be convex or ribbed. The Specification as open to inspection under Sect. 91 describes also (1) the provision at any desired position on the inner surface of the bar or plate of a transverse recess for the reception of mortar, and (2) the formation of an additional undercut rib extending lengthwise of the bar or plate and on the inner face thereof. Bars or plates are formed with such ribs by means of a wooden cylindrical mould provided with inwardly-projecting knives corresponding in number to the number of bars or plates to be produced at a time. A blown cylinder of glass is pushed into the mould and given a repeated reciprocating movement therein so that the knives compress inwardly the glass to form the ribs ; when the glass cylinder is withdrawn it is cut lengthwise to form bars or plates each provided with a rib, which is then deformed to provide an undercut formation. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,098,685. Transistor switching circuits. MOTOROLA Inc. Aug. 16, 1966 [Oct. 18, 1965], No. 36657/66. Heading H3T. A semi-conductor switching circuit comprises a plurality of gate inputs 42-45 connected through a coupling transistor 30 to the input electrode of a switching transistor 10, the coupling transistor 30 providing a drive current for the switching transistor, and a feedback transistor 24 connecting the output of the switching transistor 10 to the coupling transistor 30, the arrangement being such that when control signals are applied to the gate inputs, a heavy turn-on current for the switching transistor is provided through a series path through both the feedback and coupling transistors. As transistor 10 is switched on, the potential of point 21 falls until transistor 24 is cut-off. The low current needed to maintain transistor 10 conductive is provided through resistor 40 and the base-emitter junction of transistor 30. Should a higher maintaining current be required, transistor 24 may be arranged so that it does not completely cut-off. Then, should the load demand greater current from transistor 10 whilst switched-on, the bias on the base of transistor 24 will automatically rise to provide the greater current required to the base of transistor 10. The circuit is said to be suitable for monolithic integrated construction.
