Title: Frequency division multiplex communication systems
IPC: H04J1/06
Filed: 1972-02-24
Abstract: 1358782 Frequency multiplex transmission WESTERN ELECTRIC CO Inc 24 Feb 1972 [1 March 1971] 8476/72 Heading H4R In a frequency division multiplex communication system in which the transmitter, and/or the receiver, has two modulation stages 1 and 8, or 16 and 20, one modulation stage, the first 1, in the transmitter and/or the last, 20, in the receiver, is fed with the output of a first oscillator 4, or 19, while the other 8, or 16, is fed with a carrier derived by combining the output of the first oscillator 4, or 19, with the output of a second oscillator 6, or 15, with the combination effected and the appropriate sideband selected such that the absolute frequency of the first oscillator does not appear in the final output of the transmitter or receiver and therefore the frequency stability of that oscillator is of no importance. Preferably a pilot signal is added to the transmitted signal at 3 in the transmitter and used in a phase control loop 14, 15, at the receiver to synchronize the second oscillator 15 therein. In an alternative arrangement, Fig. 3 (not shown), a multi stage modulation system is used with each signal modulator, except the first in the transmitter and the last in the receiver, fed with carriers derived by intermodulating the outputs of pairs of modulators, so that the absolute frequencies of the oscillators, save those feeding the last modulator in the transmitter and the first in the receiver, do not affect the output.

Abstract: 1,132,502. Photo-electric flaw detection devices. RANK ORGANISATION Ltd. Feb. 14, 1967 [Feb.25, 1966], No. 8500/66. Heading G1A. A photo-cell views a moving strip of material, such as paper, through a grating whose bars are perpendicular to the direction of movement and generates a signal of a particular frequency when a flaw in the material passes by. Alternatively the strip may be stationary and the grating and photo-cell moving. An amplifier tuned to the particular frequency generates an output in response to a flaw, as distinct from noise, sufficient to switch a threshold device and step on a counter. A further grating may be provided whose bars are parallel to the direction of movement of the strip and which is oscillated by one bar width over the width of the moving strip to detect creases running the length of the strip. A further amplifier tuned to the oscillation frequency thereby responds to this type of flaw. The two gratings may be replaced by a single grating having both horizontal and vertical bars which is oscillated. The photo-cell may receive radiation, such as light or X-rays either reflected off or transmitted through the strip. The apparatus may additionally detect distortions in patterns printed on the strip by running a tonal negative in synchronism with the strip.

In a toggle operated moulding press, material is compressed in a mould 16, 17 from above and below simultaneously by rams 4 and 6, the rams moving over the same distance during the compression operation. As shown in the Figure, ram 4 is carried by a cross-piece 3 itself carried at the lower end of columns 2 slidable through the press frame 1, and ram 6 is carried by a slide 5 slidable along the columns. The rams are actuated by two double lever toggle systems having arms 12, 13 of unequal lengths, each pair of said arms being pivoted at B and A respectively to slide 5 and columns 2 respectively, and being actuated by a piston-operated rod 10. After the idle stroke in which the lower ram is stationary and the upper ram is moved downward into contact with the working material. The points of articulation P of the toggle levers and the rods 10 are so restricted that during the subsequent compression stroke the rams move over equal distances. In the embodiment shown in the left-hand side of the Figure, the articulation point P is guided along an arcuate path during the compression stroke by a holding rod 32 which moves freely through an articulation cup 37 during the idle stroke but which is pivoted, by abutment of the cup with nut M mounted on the rod, about the cup during said compression stroke. By altering the position of cup 37 and the effective length of rod 32, the point in the stroke at which the movement of P is monitored can be adjusted thus affording a control of the distance moved by the rams. In the embodiment shown in the right-hand side of the Figure the holding rod is replaced by a piston-rod slidable within a cylinder pivoted about the press frame 1. In a third embodiment the articulation point P is guided during the appropriate part of the stroke by a bar having suitable arcuate cam surfaces (see Fig. 4, not shown). In a fourth embodiment the required movement is imparted to the point P by a horizontally acting piston-rod horizontally slidable within a cylinder carried by the lower end of a piston-and-cylinder mechanism 7, 8, 9.

Title: Improvements in the hydrolysis of alkyl sulphate esters for the production of alcohols and esters
IPC: C07C29/06
Filed: 1934-03-23
Abstract: In the production of alcohols and ethers from olefines containing less than four carbon atoms, an alkyl sulphate mixture containing a substantial quantity of dialkyl sulphate is subjected to a preliminary hydrolysis by intimately mixing with not substantially more than an equal weight of water and agitating, for instance at 70--80 DEG  C. or at boiling point under reflux, until the mixture is homogeneous; and then distilling to recover the products and concentrate the sulphuric acid for use again.  The distillation is continued until the density of the distillate reaches 0,999, when the sulphuric acid in the still will be of 67--72 per cent.  When the water added is 0,75 of the weight of the alkyl esters, about equal quantities of alcohol and ether are obtained.  By adding the water at 55--60 DEG  C. the mixture reaches 70--75 DEG  C. without heating. Polymerized olefines remain dissolved in the acid and may be carbonized and rendered separable by heating a few degrees above the normal boiling-point as described in Specification 422,022, [Group III].
