Title: Improvements relating to multiplex transmission systems
Inventor: FLOOD JOHN EDWARD
IPC: C07C49/255
Filed: 1962-10-19
Abstract: 1,035,218. Multiplex pulse signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 2, 1963 [Oct. 19, 1962], No. 39704/62. Heading H4L. Relates to a multiplex pulse transmission system in which at the transmitter signal samples appearing on respective individual input channels are combined on a first common lead in time division multiplex in which pulses relating to the different channels occur in turn, and then supplied via a storage device in conjunction with output gating means to a second common lead which effects such time displacements and rearrangement of the pulses that for each channel the corresponding pulses appear in groups consisting of a fixed number of consecutive pulses relatively close together in time each group being spaced in time from corresponding groups relating to other channels. At the receiving end the converse takes place, the signals being received in the form of voltage bursts. This is termed a time compression multiplex system and is subject to " grouping noise " which is caused by the appearance at the receiver of transients at the beginning and end of each group or voltage burst. The present invention provides means for minimizing this form of distortion by arranging that each group of signal pulses is immediately preceded by at least one guard pulse and immediately succeeded by at least one guard pulse the beginning and end portions of the groups corresponding to the guard pulses being effectively ignored at the receiver. The guard pulses may be of constant amplitude or, as in the arrangement described, the guard pulse immediately preceding each signal pulse group is a repetition with corresponding amplitude modulation of the last signal pulse of the preceding group of signal pulses, and the guard pulse immediately succeeding each group of signal pulses is a duplication with corresponding amplitude modulation of the first signal pulse of the next succeeding group of signal pulses. An arrangement using tapped delay lines and gating circuits for producing the required rearrangement of the amplitude modulated pulses at the transmitter and receiver is described, Fig. 1 (not shown).

Abstract: 1,236,377. Analogue function generators. CROSFIELD ELECTRONICS Ltd. 3 Sept., 1968 [4 Sept., 1967], No. 40260/67. Heading G4G. [Also in Division H4] A function generator, e.g. for colourtone correction receives an analogue voltage x representing, e.g. a colour component to produce a voltage z representing f (x, y) from which a function generator produces a voltage representing F(z) having zero value for at least two values of z corresponding, e.g. to " black " and "first printing" tone values; a variable attenuator responsive to F(z) producing a signal #F(Z) which is combined with a signal representing a multiple mx of the input voltage to generate a voltage representing y. Voltage x is applied (Fig. 1) to summation amplifier A, also receiving voltage y fed back from the output to produce voltage (x+y) from which triple function generator x 1 , x 2 , x 3  produces function voltages # 1 (x+y), # 2 (x+y), # 3 (x+y). Voltage # 1 (x+y) is applied over attentuator # centre tapped to ground to produce voltage # #1 (x + y) applied alternatively to direct and inverting inputs of summation amplifier A 2  also receiving attentuated input voltage x, so that the output y is given by x+## 1 (x+y) (Fig. 2, not shown); a family of curves dependent on #, symmetrical about (y - x) = 0, and intersecting points P, Q at which # 1 (x+y) is zero. The function generator (Fig. 3) comprises an inverting amplifier A 3  generating a voltage to represent 2 - (x + y) applied to resistance-diode networks synthesizing a piecewise-linear function (Fig. 4) whose voltage is buffered by emitter follower T 1  applying voltage # 1  (x+y) to tapped resistor chain attentuator R with two position switch S 1 , S 2  selecting signals for the direct or inverting inputs of amplifier A 2  (Fig. 5, not shown) comprising two inverting operational amplifiers with virtual earth, and direct or inverting summing inputs; also receiving signals from the function generators x 2 , x 3 . The attentuation controls may then separately regulate, e.g. highlight contrast mid-tone density, and shadow contrast in either sense.

Abstract: 1402295 Transferring boxes between conveyers; endless pusher conveyers ORGANISATION RALFS KG 5 Sept 1972 [6 Sept 1971] 41105/72 Heading B8A Boxes on a conveyer 23 are transferred to a conveyer 17 by pairs of pushers F1 or F2 on conveyer chains 4, 21. A stop wheel 36 carried by a slider P, holds the boxes from proceeding from the conveyer 23. The stop is retracted when a pair of the pushers F1 or F2 pass from the lower run of the chains 4, 21, around a bowshaped control member M. The member M is rearwardly slidable due to its engagement by the pushers. In addition to retracting the slide P, it operates a switch J. This cuts off current to a drive motor G of the chains 4, 21. When the leading box waiting on the conveyer 23 is released by the stop 36, it travels on rollers 9 into a position to be engaged by the pushers F1, F2, when these again commence movement. This is brought about by the leading end of the box engaging a switch D. When the pushers proceed, the member M is again released and this releases the slide P and causes the stop wheel 36 to be repositioned.

In Figs. 1, 2, the second part 8 includes a pair of upstanding pillars 9 having pins 11 extending into holes 4 in the first part, the clearance between pins 11 and holes 4 defining the free lateral movement in the first position. Nuts 10 having collars 10a are screwthreaded on to pillars 11, and may be screwed up the pillars so that the collars 10a enter holes 4 to prevent relative lateral movement, and so that the part 1 and load carrier 2 are supported by the nuts so that sensor 6 may be removed. In Figs. 7, 8, the load carrier includes a depending leg 14 on which the first part 13 is screw threaded. The second part includes a base-plate 20, a part cylinder 22 within which the load sensor 19 is housed, and screws 24 in extension 26 of the cylinder. In the first position, lateral relative movement is limited by the clearance between the top of the cylinder 22 and a groove 15 in the part 13. To achieve the second position in which sensor 19 may be replaced, screws 24 are raised so that their pointed heads engage and lift the part 13. During initial assembly of the device the groove 15 and the upper end cylinder 22 define the relative horizontal positions of the first and second parts 13, 20, part 13 then being raised by means of screws 24 to permit insertion of the sensor 19. In a modification of Fig. 7 part 13 is replaced by a plate (38) fixed to the underside of a tank or platform Figs. 11, 12 (not shown). In a further modification, Fig. 9, the first part comprises members 28, 29 screw threadedly engaged, the member 28 having a depending part cylinder 34 co-operating with a groove 36 in the second part 29.

Title: Method of separating benzoic acid from the crude product of the oxidation of toluene
Filed: 1961-11-24
Abstract: <FORM:0961062/C1/1> Benzoic acid is separated from the crude oxidation product of toluene, after preliminary distillation to remove excess toluene, by passing superheated steam, introduced through line 1a, through the product contained in vessel 1.  The benzoic acid and other volatile components distil over with the steam via line 2a into the heat-insulated vessel 2, leaving a residue of non-volatile components such as dicarboxylic acids and esters in vessel 1. Vessel 2 contains boiling water (not more than 40 Kgs. of water/Kg. of benzoic acid) up to level 4, into which pass the vapours from line 2a.  The benzoic acid collects as a molten layer 5 under the boiling water, and the more volatile components, i.e. the toluene residue, benzaldehyde and aliphatic monocarboxylic acids are distilled over with saturated steam at 100 DEG C. and condense in the cooling coil 3b of the cooler 3.  The molten layer of benzoic acid in vessel 2 is introduced into a crystallizer (not shown) and allowed to crystallize. Specification 961,061 is referred to.
