Title: Vehicle suspension units
IPC: F16F9/084
Filed: 1974-11-29
Abstract: 1482021 Combination shock absorbers and rolling diaphragm fluid springs ARMSTRONG PATENTS CO Ltd 29 Nov 1974 [3 Jan 1974] 00188/74 Heading F2S In a vehicle suspension unit comprising a telescopic hydraulic shock absorber (the pistonrod 12 of which carries an end cap 18 bearing a tubular dirt shield 16) and a rolling diaphragm fluid spring, one end of the diaphragm 14 is attached to the dirt shield 16 by a further tube 24 between which and the dirt shield the diaphragm end is clamped by an annular inward deformation of both tubes, the further tube 24 extending over a major portion of the length of the diaphragm, even when the piston-rod is in its fully extended position. The tube 24 controls radial expansion of the diaphragm. Preferably the tube 24 is of such a length that it extends to or beyond the fold in the diaphragm even when the piston-rod is fully extended. Should however the length of the tube 24 be insufficient to enclose the diaphragm at all times, the free end of the tube 24 is flared outwardly, as shown at 34. The other end of the diaphragm is attached to the shock absorber cylinder 10 by inward deformation of a retainer ring 20 and of the cylinder itself. The shock absorber may be of the single or double tube type.

Title: Circuit arrangement for demodulating a pal-colour signal
IPC: H01L25/03
Filed: 1968-01-05
Abstract: 1,204,036. Colour television. MULLARD Ltd. (Philips Gloeilampenfabrieken N.V.). 5 Jan., 1968, No. 850/68. Addition to 1,106,944. Heading H4F. In a circuit arrangement for demodulating a PAL system colour sub-carrier signal F, a signal T having the same frequency as the subcarrier and a phase not 90 degrees different from the phases in which the red and blue colourdifference signals R-Y and B-Y are modulated on the sub-carrier and with a constant amplitude at least equal to the amplitude of the modulated sub-carrier, is added to the sub-carrier in adding stage 1, and a similar signal-T of opposite polarity, i.e. 180 degrees differing in phase, is also added to the sub-carrier in adding stage 1a. The output of adder 1 is fed via delay line DL having a delay period equal to the reversal period of the R-Y component in the subcarrier, i.e. one television line period, to an envelope detector 2, and the output of adder 1a is fed directly to an envelope detector 3 of opposite polarity. The outputs of detectors 2 and 3 are combined to give the blue colour difference signal (B-Y). To obtain the red colour-difference signal (R-Y) the output of delay line DL is fed to an envelope detector 5 and the output of adder 1 is fed via a damping member 4 simulating the decrease in amplitude on the delay line, to an envelope detector 6. The rectifiers in the two detectors 5 and 6 are alternately made operative by means of a switching signal so that the polarity of the resulting R-Y signal at the combined output of detectors 5 and 6 is constant and does not change polarity from line to line, i.e. as described in the parent Specification 1,106,944. The improvement of this Specification over the parent Specification is that the (B-Y) component is derived without an associated D.C. component. Variation in the phase position of the carrier signal T causes the two colour signals R-Y and B-Y to be influenced differently and this effect may be utilized for adjusting the hue of the colour television receiver.

Abstract: PURPOSE:To ensure the stable identification for a character pitch by setting the range of existence for the width of a character group and replacing the upper limit value of the character group which is to be the highest frequency of appearance obtained by a prescribed allowance range in accordance with the frequency of appearance of information to obtain a character width class. CONSTITUTION:A scanner 1 writes a character train image to a character train image memory 2. A character group extractor 3 detects the image of a character part and stores both the position of initiation and the size of each character group to a character group register 4. A deciding part 9 produces an identification function from the value of frequency of appearance counted within a section by the lower and upper value B of the width of a character group having the highest frequency value in a fixed interval, i.e., the contents of a 1-character initial class register 14, the upper limit value of a character width class, i.e., the contents of an upper limit value register 81, and an increment compared with the value of frequency of appearance, i.e., the contents of an increment frequency register 88. Then it is decided based on the value of the identification function whether the character train an equal pitch or variable pitch.
