Title: Railway trailer hitch
IPC: B61D45/00
Filed: 1969-09-12
Abstract: 1275667 Securing road trailers to railway flat cars ACF INDUSTRIES Inc 12 Sept 1969 [16 Sept 1968] 45059/69 Heading B7L A hitch for securing a trailer on a railway flat car comprises a strut 14 pivoted by pins 42 to a frame 40 and pivotally mounting a fifth wheel support 22, there being pivotally connected between the upper end of the strut and a base plate 12 a leg 26 formed of telescoping frames 32, 34 between which are located hydraulic cushioning units 72, 74 which bias the strut 14, to its upright position and absorb forces tending to pivot the strut in either direction away from this position, the hitch further including means to rigidly locate the strut 14 in its upright position if the capability of the units 72, 74 falls below a predetermined level. The means to locate the strut rigidly comprises a piston 124 which under normal working conditions is retained within a bore 110 by the units 72, 74, but which if the capability of the units falls is urged out from the bore by the pressure of a compressible liquid in chamber 148 so that locking pins 112, 114 are released from engagement with lugs 126 of the piston and urged by spring 118 outwardly into apertures 156, 158 of the frames 32, 34 thereby rigidly locking them together. In a modification the compressible liquid is replaced by Belleville springs. The hitch is collapsed by rotation of a screw 44 whereby the bottom of strut 14 and frame 40 are moved backwards towards pivots 28. The cushioning units 74, 76 are operative when the strut 14 is pivoted in either direction by being located between plates 78, 88 which abut cross members 60, 62, 68 and 70 of the frames 32, 34 according to the direction of pivoting.
Patent GB-451400-A (GB)
Abstract: 451,400. Typewriters; compositors' appliances. BOLONGARO, J. D., Charlottesville, Virginia, U.S.A. Nov. 27, 1935, No. 32907. Convention date, Nov. 27, 1934. [Classes 100 (iii) and 100 (iv)] To facilitate the laying out of matter printed from a typewritten copy, a typewriter is provided with means comprising a periodically operated counter for determining the number of printed lines corresponding to the copy. In the apparatus shown in Figs. 1 and 2, a counter 86 and a frame 31, 32 supporting driving-means, therefor are mounted on a bracket 30 at the rear of the typewriter 1. The driving-means comprises a cam 63 on a shaft 57 provided with a pinion 56 gearing with a pinion 54 which gears with a pinion 50 on a shaft 48. The cam operates a lever 81 which engages the counter-operating arm 85. A ratchet-wheel 41 on the shaft 48 engages a pawl 44 on a shaft 34 provided with a pinion 36 engaging a rack 16 which is suspended from a bar 15 secured to arms 13 on the feed-rack 11 of the typewriter. The pawl 44 drives the shaft 48 during letter-spacing movement of the platen-carriage 3, reverse movement and overrunning being prevented by pawls 45, 52 and ratchet-wheels 42, 51. Each of the pinions 36, 50 and also the feed-pinion 20 has twelve teeth so that a complete revolution of these pinions occurs when the platen - carriage traverses twelve letter-spaces. The number of teeth on the pinion 56 is such that a complete revolution, with consequent operation of the counter, corresponds to a printed line of predetermined length and fount. To permit change of the pinion 56, according to the fount and length of the line, the intermediate pinion 54 is mounted on a revoluble disc 47 which is secured by means of a screw 46 passing through a slot 49. The shaft 57 is connected to a shaft 59 provided. with a knob 67, and a disc 66 having marks for indicating the position of the cam 63. The knob is employed for turning the cam when it is desired to operate the cam independently of the typewriter. To disable the counter, the pinions 56, 54 are disconnected by pushing inwards the knob, a catch-lever 69 being depressed to maintain disconnection. In another form of apparatus, a counter and driving means therefor, similar to those described above, are arranged at the side of the typewriter, and the driving-means is connected by gearing to the escapement-wheel of the typewriter.

Title: Optical arrangement for colour television cameras
Inventor: DILLENBURGER WOLFGANG
IPC: H04N9/097
Filed: 1968-09-24
Abstract: 1,213,336. Optical systems. FERNSEH G.m.b.H. Sept.24, 1968 [Sept.26, 1967], No. 45319/68. Heading G2J. [Also in Division H4] Relates to an optical arrangement for a colour television camera which compensates for the different sensitivity of photo-conductive camera tubes to different spectral ranges and which achieves this object without the use of filters or other light obstructive elements. As shown the arrangement includes a conventional means for splitting the light entering the camera objective 1 into a luminance component, imaged at 3 and three chrominance components, red R, green G and blue B imaged at 10, 16 and 13 using a partially reflecting mirror 2, fully reflecting mirrors 5, 11 and 14 and dichroic mirrors 7 and 8. A further objective lens 6 converts rays of light from the secondary image 4 into a parallel beam. Lenses 9, 13 and 15 focus the colour components onto their respective camera tubes. The relative aperture of each of these lenses is arranged to be proportional to the sensitivity of the associated camera tube to the respective colour, while keeping the lenses of equal physical size, the relative aperture being defined as f/d where f is the focal length and d is the diameter of the effective aperture of the lens. This requirement results in each of the lenses having different focal lengths, as shown. The resultant images at the camera tube are hence of different sizes, the spectral ranges to which the camera tubes are most sensitive having the largest image, resulting in a lower incident light flux per unit area on the photosensitive layers for the larger image Fig. 2 (not shown) illustrates a corresponding system for producing the three chrominance signals only.

Title: Colour television system
IPC: H04N9/68
Filed: 1973-09-28
Abstract: 1453588 Colour television DECCA Ltd 19 Sept 1974 [28 Sept 1973] 45582/73 Heading H4F To improve the vertical definition of the luminance component of a television signal which is obtained by decoding a luminance signal and a line-sequential chrominance component (R-M, G-M, B-M) of lesser bandwidth than the luminance signal a decoder is provided which is arranged to compare each line of an input signal with an earlier line of corresponding chrominance and reduced definition in order to derive signals which denote vertical luminance transitions. As shown in Fig. 1 a video signal, e.g. from a video-disc player, is fed to input 10 and via compensating delay 11, series connected one line period delay lines 14, 15 and 16 having a feedback loop to an adder 13 including an amplitude reducing device, e.g. an amplitude halver as shown, adding and subtracting stages 17-22, and low pass filter 23 to an adder 12. In addition the inputs of delay lines 14-16 are tapped off to a set of commutating switches 24 which provide low-frequency continuous chrominance components (R-M), (G-M) and (B-M) to separate channels, matrices 25 to 26 forming a composite output signal. In this arrangement the output of adder 13 comprises luminance components denoting vertical transistions. The outputs of adders 17 and 18 comprise luminance signals of low definition which are combined with the input signal at input 10 to produce at the output of adder 22 a chrominance signal combined with spurious edge signals so that the output of adder 12 comprises the input luminance of full band-width together with some spurious, band-width restricted, signals which produce, subsequent to a sharp vertical luminance transition in a picture obtained at a receiver, a ringing or oscillation. A second embodiment of the decoder is described with reference to Fig. 2. An encoder, Specification 1,453,589, for use with the above decoder which reduces the luminance ringing thereof and preferably also reduces the vertical definition of each of the line sequential chrominance components, comprises as shown in Fig. 3 a series of one line period delay lines 31-36 to which a luminance signal is applied, processed 37-41 as shown and added 47 to a line-sequential chrominance signal from processor 30. To reduce the vertical definition of the chrominance components the processor 30 Specification 1,453,590, includes a series arrangement of six one line period delays and appropriate summing amplifiers (Figs. 4 and 5, not shown).
