Title: Process for preparing pantothenyl alcohol
IPC: C07C233/16
Filed: 1955-11-14
Abstract: Pantothenyl alcohol is prepared by reacting a  : g  - dihydroxy - b : b  - dimethyl - g  - butyramide with allyl alcohol or with 3-aminopropanol-1 in the presence of a solvent such as an aliphatic alcohol.  The reaction when using 3-aminopropanol-1, and preferably also when using allyl alcohol, is carried out at a temperature between 30 DEG  and 200 DEG  C. at a pressure between 1 and 50 atmospheres and more preferably in either case at 100 DEG  to 200 DEG C. at 10 to 30 atmospheres.  When using allyl alcohol it is advantageous to carry out the reaction in the presence of ammonia or a compound yielding it under the reaction conditions, e.g. excess of the amide.  The beginning of the reaction may be accelerated by adding a small amount of an alkali metal or an alkali metal hydroxide.  Examples illustrate the various features of the invention, using propyl alcohol, water and methanol as solvents. Specification 478,304, [Group IV], is referred to.

Title: Improvements in or relating to interdigital delay lines for use in travelling wave tubes
IPC: H01P9/04
Filed: 1952-12-23
Abstract: 738,405. Travelling wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 23, 1952 [Dec. 29, 1951], No. 32655/52. Class 39 (1). [Also in Group XL (b)] The delay line of a travel. ling wave tube comprises two interleaved combs, each tooth of one comb overlapping the corresponding tooth of the other comb by about one - third of the width of the line, and the pair of teeth being very close together at the area of overlap, while the distance between consecutive pairs of teeth over the region of overlap is substantially the same as the distance between two adjacent teeth of either comb outside the region of overlap. The fingers preferably decrease in cross section from their base to their apex. The tube is preferably a travelling wave oscillator as claimed in Specification 699,893, which utilizes a mode having negative phase velocity. The line is wider than conventional lines, since the interleaving is over a shorter distance, and this allows a greater beam width so as to increase the power output. The tapering of the fingers increases the uniformity of the D.C. electric field in the interaction space. It is stated that this construction results in a wave of negative phase velocity over the entire width of the line as compared with an untapered form in which the desired mode only extends over the central portion of the line for a third of its width, the side parts of the line carrying space harmonics of positive phase velocity. In one form, Fig. 3, the fingers have reduced end portions 7 of about half the cross-section of and the same length as portions 6. In a modification, Fig. 4 (not shown), the tapering step is on both sides of each finger. In another form, Fig. 5 (not shown), the fingers are triangular prisms.

Title: Solid state colour television cameras
IPC: H04N9/04
Filed: 1975-08-11
Abstract: 1522487 Television SONY CORP 11 Aug 1975 [29 Aug 1974 30 Aug 1974] 33403/75 Heading H4F In a solid state colour television camera a 3- phase CCD array of detectors 10, Fig. 5 (described in detail w.r.t. Figs. 1 to 3 (not shown)) is disposed behind a special filter 20a so as to provide an output signal free of "folded error" (i.e. disturbance due to frequency overlapping DC and sideband signal components). The filter comprises a corresponding array of windows one in front of each detector 1 i-j. The colour selectivities of the windows are chosen such that (1) green light is passed by each window and (2) red and blue light are passed such that their horizontal periods differ and the signals representing them are of alternate polarity in adjacent line scan intervals. The waveforms of Fig. 5 show that filter 20a satisfies these requirements. The horizontal alignment pitch of the detectors li-j is # H  giving a modulated "green" signal S SBG  Fig. 7A on a carrier of frequency 1/# H . As shown in Fig. 5 the carrier frequencies of the "red" and "blue" signals are 1/2# H  and 1/3# H  respectively, Fig. 7A. Fig. 6 shows the output processing stages of the CCD 10. Light from a scene 14 is focused 15, through a first filter F, which limits the bandwidths of the "red" and "blue signals, then through filter 20, which satisfies the above conditions (1) and (2), onto CCD 10. The output of CCD 10 has the frequency spectrum shown in Figs. 7A and B for "odd" and "even" line periods respectively, this signal is simultaneously applied to low pass filter 25 and compensating delay 29. Filter 25 passes the 0À2 MHz DC components only. These are subtracted 26 from the delayed signal to produce the spectrum of Fig. 7C. This is applied to a one line delay 27 and second subtractor 30 which also receives the one line delay output to provide as output of subtractor 30 the spectrum of Fig. 7E. That is the blue and red modulations since these are of line sequential opposing phase and therefore do not cancel in subtractor 30 as do the other components. Adder 28 receives the outputs of one line delay 27 and compensating delay 29 to form the spectrum of Fig. 7D. That is the green modulation and DC component by virtue of phase cancellation in red and blue components. Respective band pass filters 31R, 31B and detectors 32R, 32B derive red and green signals from the outputs of subtractor 30 (i.e. Fig. 7E) and apply these along with the output of adder 28 to the matrixing circuit 34. In another embodiment two CCD arrays having the filters described w.r.t. Fig. 8 are employed. In this case one filter satisfies (1) above while the other satisfies (2). Processing of the outputs is described w.r.t. Figs. 9 and 10 (not shown). In another embodiment two CCD arrays are employed which are spaced by 1/# H  as above but have filters as described w.r.t. Fig. 11. The CCD output processing is described w.r.t. Figs. 13 and 14 (not shown). In the embodiment involving relative spacings between plural CCD arrays the spacings are instrumental in reducing the "folded error".
