Title: Improvements in or relating to electromagnetic change-speed gears
IPC: F16H61/02
Filed: 1952-01-31
Abstract: 702,809. Variable-speed gearing. SOC. ANON. FRANCAISE DU FERODO. Jan. 31, 1952 [Feb. 19, 1951], No. 2598/52. Class 80 (2) A change speed gear having epicyclic trains controlled by electromagnets is arranged so that in the neutral position of the gears at least one of the electromagnets is energized so that with the input shaft rotating and the output shaft stationary all the main rotative members of the gear are rotating except those rigid with the output shaft. Thus, when passing from the neutral to first speed, the inertia effects of the gear members balance one another and this avoids sudden torque reaction on the output shaft. As shown, two epicyclic trains are in series between input and output shafts 1, 5. Electromagnets 4, 7 are fixed to the shafts 1, 5 and electromagnets 3, 6 are fixed to the casing 12. The first train has planets 16 meshing a sun 13 on the shaft 1 and internal teeth 2 on a disc 14 between magnets 3, 4. The second train has planets 11 carried by the shaft 5 meshing a sun 19 on a disc 10 between the magnets 6, 7 and an internal gear 17 on the planet carrier of the first train. Four gear ratios are obtained, two of the four magnets being energized at each ratio. When the gear lever is in neutral position it engages contacts 8, 9 to energize magnet 4 so that with the output shaft 5 stationary rotation of the shaft 1 causes all moving parts of the gearing to rotate, the disc 10 rotating in the opposite direction to the other members.

Title: Mold cooling control apparatus for a glassware forming machine
IPC: C03B9/38
Filed: 1966-01-20
Abstract: <PICT:1061116/C1/1> An improvement for mould cooling in a glassware forming machine of the type having at least one mould which can be closed to form molten glass and then opened for removal of the formed object, and also having driven means for opening and closing the mould including a driven control member operable to effect the opening and closing in timed sequence, comprises conduit means 22, 28 (Fig. 2, not shown) having an outlet 34 for directing cooling air on to said mould 14, the conduit being mounted on the machine by a base which defines an inlet 32 connected to a source of air under pressure, a damper 36 pivotally supported on said conduit means in one of its said openings for movement between a closed and an open position, means 48 biasing the damper into one of its said positions, a fluid motor 54 operable responsive to fluid under pressure to place said damper in its other position, and control means 20 for said fluid motor including a valve connected thereto and connectible with a source of fluid under pressure, and valve actuating means 74 carried by the control member of the machine to operate said valve and thereby effect cooling of the mould only when it is closed.  The description relates to a multi-section Hartford I.G. machine in which the damper 36 is located in the inlet 32. The damper is biased in its open position by a spring 48 attached to a lug 50 (Fig. 6) on the damper and a pin on the machine frame.  The damper has a boss 46 (Fig. 5, not shown) on its upper surface which bears against an adjustable stop 44 to regulate the degree of opening and also has a lug 42 (Fig.4, not shown) which bears against an adjustable stop 40 to regulate the degree of closure of the inlet.  In this machine it is preferred that some cooling air be allowed to blow upon the moulds even when the damper is in its closed position.  To close the damper an extension 62 of the fluid motor 54 bears against a boss 66 on the upper surface of the damper. When the motor 54 reverses the damper opens against the action of the spring 48.  The opening and closing of the damper is worked in timed relationship with the closing and opening of the moulds by the machine timer drum 20.

Title: Improvements in or connected with apparatus for effecting and controlling the shrinkage of textile fabrics
IPC: D06C21/00
Filed: 1943-02-18
Abstract: 563,638. Shrinking fabrics. HADFIELD, J. J., and BAMFORD, D'. Feb. 18, 1943, No. 2695. [Class 42 (i)] Textile fabrics, wetted or conditioned, are shrunk by conveying them on a tensioned endless and elastic rubber band to a revolving burnished drying cylinder, the tension or stretch in the band being relaxed over each successive length of the band where it contacts with the intervening fabric against the cylinder which is so located that the relaxing band and fabric follow the contour thereof while shrinkage takes place ; the extent of such shrinkage is proportional to the contraction of each successive length of the band which is supported upon and driven by revolvable rollers, one of which is driven through variable speed mechanism at a variable higher speed than the preceding roller so that a portion of the band is tensioned or stretched when it receives the wetted or conditioned fabric. As shown, the endless, elastic, rubber band a is supported by adjustable rollers b<1> . . . b<4>, the roller b<3> being positively driven and driving the roller b<4> at a faster speed through a variable speed gear, e.g. that known as the " Reeves " gear, by varying the speed of the roller b<4> relative to that of the roller b<3> the shrinkage of the fabric f is controlled. A roller or rollers c directs the wetted or conditioned fabric on to the stretched portion of the band and the highly-burnished, heated, drying cylinder d, which may be frictionally driven from the roller b<4>, deflects the band and fabric into a concave path where the band relaxes, the fabric contracts and the shrinkage is made permanent. The shrunken fabric is further dried by passing around the heated drying cylinder h and is finally batched. Specifications 359,759, 371,976 and 372,803 are referred to.
Patent GB-668777-A (GB)
Title: Improvements in or relating to pulse synchronising apparatus
IPC: H03L7/085
Filed: 1950-02-02
Abstract: 668,777. Automatic control of frequency and phase. SPERRY CORPORATION. Feb. 2, 1950 [Feb. 2, 1949], No. 2738/50. Class 38 (iv). [Also in Group XL (c)] To synchronize an H.F. oscillator by L.F. input pulses, its output is fed to a frequency divider to produce short duration L.F. output pulses which are compared in phase with the input pulses to derive a frequency control voltage for the oscillation. Recurrent pulses having a predetermined time phase relationship to a series of input pulses may also be produced by a delay circuit interposed between the frequency divider and the phase-comparator, the output being taken from the frequency-divider. As shown, Fig. 1, the phase-comparator is a pentode, normally biased to cut-off, with the delayed output pulses D fed to the first grid, and the synchronizing pulses fed through a differentiating circuit 12, 13 to produce pulses B, Fig. 2, on the third grid. A short timeconstant network 27, 28 in the anode circuit prevents oscillation through the feedback loop, and the " smoothed " output is taken from a long time-constant circuit 24, 26 to the frequency controlling reactance-tube-circuit. Provided the short duration feed-back pulse D occurs somewhere along the differentiated input pulse B and Q and Q<SP>1</SP> the voltage at the anode will be varied to control the frequency and maintain synchronization. Initial " pull in is accomplished by a manually variable resistance 29 in the anode supply circuit which provides initial voltage variation to effect synchronization, since when pulses D occur between pulses B on switching on, the average voltage at the anode due to pulses D is constant and pulses B produce no effect without a pulse on the control grid. The system may be applied to synchronizing the sweep of a cathode-ray tube indicator with the output of a Loran receiver. The videoamplifier output is applied to the vertical deflection circuit and the synchronizing circuit, Fig. 3 (not shown), and the synchronized and phase shifted output pulses are used to control the sweep generator.

Title: Cathode ray tubes and display systems including cathode ray tubes
IPC: H01J31/20
Filed: 1952-02-01
Abstract: 713,875. Colour television tubes. EDISON SWAN ELECTRIC CO., Ltd. Feb. 1, 1952 [Feb. 1, 1951]; No. 2784/52. Class 39(1) A colour television receiver tube comprises a perforated target 4, Fig. 2, and an optically transparent electrode 6 for reflecting the electron beam 2 back on to a phosphor pattern R, G, B, carried on the front surface of the target 4. Colour selection is accomplished by varying the angle of approach of the beam to the target, the potential difference between the target and the reflecting electrode, the velocity of the beam, or by a combination of these methods. The target may be inclined generally at an angle, preferably 45 degrees, to the electron beam. In a rectilinear tube the target may be inclined, or the electron gun may be located in an envelope portion inclined at an angle to the axis of the main envelope. To compensate for variation of the angle of approach of the beam to the target in scanning one, or a combination of the following methods 'may be employed. The target may be concave. Provision may be made for introducing electrostatically or magnetically, additional compensatory deflection of the beam. The spacing between the perforations in the target and correspondingly the spacing of the co-operating phosphor areas may be progressively varied over the target. The distance between the target and the reflecting electrode may be varied. Cr, the velocity of the incident beam may be varied by varying the voltage of the reflector voltage with the position of the beam in its scanning circle. Provision may be made for correction of Keystone distortion by compensating the currents applied to deflection coils, for example. Three electron beams may be used. The electron guns may be aligned in one plane, converging towards the centre of the screen. As shown, Fig. 6b, the guns 31, 32, 33 and apertures 37, 38 in focusing anode 34 and final anode 35 are so aligned that the three beams intersect at the surface of the tilted target 4. The guns may be parallel to one another, in which case convergence of the beams to a common point may be achieved by the use of an electrostatic or magnetic lenses located between the final anode and the deflection coils. In another arrangement, the electron guns are positioned in triangular formation about the axis of the tube. In another embodiment employing a single gun, the angle of approach of the beam to the target is varied by means of a deflecting coil. The reflecting electrode may have a conductive coating, such as obtained by treatment with tin chloride, or a wire mesh, and may be located on the end wall of the tube or on a separate glass plate. The target may be a thin copper sheet in which the perforations are formed by etching. The phosphors may be applied by settling or spraying through a mask, or by painting. The phosphor areas may be of circular, oval, square or lozenge shape arranged between circular or oval perforations. The phosphor areas may be stripes between rows of square shaped perforations.

[Class 40 (v)] To ensure a clear-cut directional indication, free from ambiguity due to waves reflected from a nearby conductor, the receiving aerial system is given a pick-up characteristic which, as shown in Fig. 4, has a zero direction lying inside a small solid angle of full-strength reception, outside which it again receives no signals. Each of the receiving aerials 1 ... 4, Fig. 1 has a sharply-directional characteristic as shown in Fig. 3. They may consist of dipoles mounted inside a reflector, or of separate " beam " arrays, and are arranged in two pairs 1, 2 and 3, 4 set mutually at right angles. The incoming signals from 1, 2 are fed in opposition to a receiver 5, whilst those from 3, 4 are similarly fed to a receiver 5<1>, the rectified output being added in an indicator 6 to give the effect shown in Fig. 4. Alternatively the two opposed voltages from each pair of aerials may be fed direct to a common receiver through networks which. impose a phase-shift of 90‹.
