Title: Improvements relating to gear cutting machines
IPC: B23F5/20
Filed: 1959-12-18
Abstract: 867,964. Gear-cutting. GLEASON WORKS. Dec. 18, 1959 [Dec. 19, 1958], No. 43107/59. Class 83 (3). A gear-cutting machine comprises a slide 65, Fig. 4, reciprocable on a tool head 54, a tool carrier 61 pivoted to the slide and a crank 58 for causing swinging motion of the carrier about an axis perpendicular to the direction of reciprocation, the slide being reciprocated in time with the rotation of the crank. A gearblank G, Fig. 1, is mounted on a head 15 adjustable in the direction of the blank axis 14 on a base 16 swinging on a slide 17 about an axis 18 intersecting the axis 14 and the toolcradle axis 12. The slide 17 is adjustable in the direction of the axis 12. A motor 19, Fig. 2, rotates the work-spindle 13 and oscillates the cradle 11 through rate-of-roll change gears 22, a cam 28, a bell-crank 29 and a connecting rod 31, the movement of the cradle during cutting being in a constant proportion to that of shafts 24, 27 but being faster and at a varying rate during a return roll. A cam 32 moves the work to-and-from cutting position. Index change gears 38 in the drive to the work-spindle cause the blank to be rotated one or more teeth between the cutting operations. The planing tools T, T<SP>1</SP> are reciprocated by a motor 42 through a shaft 45, coaxial with the cradle, and shafts 53. Each tool is clamped by a screw 50, Fig. 3, to a tool-carrier 61 oscillated about a pivot 63 by a crank-pin 58 on the shaft 53. The pivot 63 is carried on the slide 65 reciprocated by cams 68, 69 on the shaft 53 engaging followers 71, 72 on the slide. The crank thus effects the cutting stroke and the cams effect the relief movements. The resultant motion of the tool tip is a path P, p<SP>1</SP> which approximates over the cutting section to the circular path of a milling-cutter blade rotating about the axis 64 of the pivot 63. The slide 65 reciprocates in a direction making an angle with the cradle axis approximately equal to the complement of the pressure angle. If the angle is exactly equal to the effective pressure angle of the sidecutting edge E, the teeth cut are straight. Otherwise, the edge E describes a shallow conical surface and the teeth are crowned. To vary the direction of the path P, p<SP>1</SP> the slideways 66 carrying the slide 65 are adjusted angularly against a vernier 78 and a scale 77. The length of the path P, P<SP>1</SP> may be adjusted by varying the eccentricity of the crank-pin 58 through a clutch 79 and dial 85, at the same time re-adjusting the phase relationship of the cams 68, 69 snd the crank-pin by means of a dial 88 and a clutch 89. The tool mechanisms are carried in heads 54 which are angularly adjustable, the phase relationship between the tools then being adjusted by a dial 91 and a clutch 92. Reference has been directed by the Comptroller to Specification 778,476.

A device for use in filling a crate or like container 17 with fruit, bulbs, &c., comprises a frame 1 provided with two opposed pronged elements 28, 29 having staggered tines and which, when under the influence of an increasing load of fruit, swing gradually towards the bottom of the crate in opposition to the pressure of a pressure absorbing device 44 so that the elements 28, 29 assume a vertical position from which they can be lifted vertically. A crate 17 is placed on a bearer 10 and the fruit to be packed is placed in a gully formed by tines 28, 29 mounted on rotatably supported axles 30, 31. The device 44, controlling the turning of the tines 28, 29 due to the weight of fruit thereon, comprises a piece 45 sliding along a fixed bar 46, to which guides 42, 43 are attached and which is connected to the frame 1 by a tension spring 49. Cranks 36, 37 secured to the axles 30, 31 press the guides 42, 43 downwardly against the pressure of the spring 49 so that the fruit is lowered gradually into the crate. The tines become vertical when rolls 40, 41 leave the guides 42, 43 which are then moved upwardly by the spring 49. A foot operated lever 54 lifts the upper part of the frame 1 to lift the tines 28, 29 vertically out of the crate 17. When no fruit is on the tines they are held in the position shown in Fig. 1 by springs 34, 35. In a modification, Fig. 5 (not shown), the tines are covered with soft rubber which extends beyond their ends to form flexible portions. The uppersides of the tines may also be covered by pads foam rubber or felt to prevent damage to the fruit.

Abstract: 1338129 Photo-metric analyzer COMMISSARIAT A L'ENERGIE ATOMIQUE 20 Sept 1971 [ 23 Sept 1970] 43788/71 Heading G1A In a photo-metric analyzer for the determination of element(s) in a solution 12, a light source 4 provides two beams I & II of different wavelengths by means of a semireflector 9 having a variable co-efficient of attenuation across its surface, and monochromators or filters 5 & 6. The beams are alternately passed through a vessel 11 containing the solution 12 by means of a modulator demodulator system 2 which is shown in detail in Fig.2. The modulator demodulator comprises two discs each having two pairs of openings B and C and the "B" openings each have an associated inclined mirror A. The discs 13 & 14 are mounted on a shaft 15 which is driven by a motor 16 so as to alternately allow the passage of beams I and II through the vessel 11. If the presence of only one element in the solution 12 is being monitored then the light beams comprise one, I, whose wavelength is susceptible to absorption by the element, and one, II, (acting as a reference) not so susceptible. The reference beam II has an attenuator system 18 controlled by a servosystem in its path. The beams maybe received by a single light detector 17 or they may each have a corresponding one of a pair of light detectors mounted in opposition. The latter arrangement also can be used for relative measurement of the concentration of two elements in the solution 12, the wavelengths of the beams I & II each being susceptible to absorption by a different one of the elements.

Title: Recording and reproducing system for colour video signal
IPC: H04N9/82
Filed: 1970-09-16
Abstract: 1326079 Colour television SONY CORP 16 Sept 1970 [26 Jan 1970] 44241/70 Heading H4F A system for recording colour video information comprising a luminance and a chrominance signal combined as a single signal applied to (for example) a magnetic recording head comprises means for processing the input signal (e.g. NTSC) by separating the luminance and chrominance components by means of filters 2, 6, frequency-modulating at 3 a carrier with the luminance signal, frequency-converting at 7 the chrominance signal to a band of lower frequency than the new luminance signal and combining the new signals at 5 for recording. Oscillator 15 is locked to the chrominance subcarrier frequency by means of gate 12, and its output is divided by 14 at 17 and multiplied by 3 at 18 to provide a frequency of about 0À767 MHz which is supplied to converter 16 which generates a sum frequency used to convert the chrominance sub-carrier to 0À767 MHz. The new luminance signal band extends from 3À5 MHz (sync. level) to 6À5 MHz (white level). In accordance with the invention these frequencies are so chosen that the second harmonic of the chrominance subcarrier as recorded (a harmonic found to be generated by the recording process) is an odd multiple of half the line frequency, thus minimizing its interference with the luminance signal in the output from tape, since the interference will generally cancel in successive lines. Fig. 4 (not shown) illustrates the re-conversion to NTSC standard of the tape replay output. Specification 1,326,078 is referred to.
