Title: Improvements in or relating to electric pulse communication systems
IPC: H04J3/16
Filed: 1945-08-18
Abstract: 600,955. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 18, 1945, No. 21148. Convention date, Aug. 19, 1944. [Class 40 (v)] In a multiplex pulse communication system, means are provided in at least one of the channels to modify the relative pulse time positions of the modulated pulse train and corresponding means at the receiver restore the original time positions. The received interleaved pulse train may comprise substantially equally spaced pulses. In one embodiment of the type described in Specification 592,585, employing four channels, the pulse generators and modulators 2, 6, 7, 8, Fig. 1, of the type described in Specifications 600,244 or 600,254, are fed from a base wave source 1, with the necessary phase-shifts in circuits 3, 4, 5, and from the signal sources 9, 10, 11, 12. The modulator outputs are mixed 'and fed to a radio transmitter 13. Interposed between the modulator 8 for the fourth channel and transmitter 13 is a pulse position translator 14 of the type described in Specification 600,256. The pulse outputs for channels one, two and three are constituted by pairs 1a, 1b, 1c, 1d, 2a, 2b, &c., Fig. 4c, whilst the output from the fourth channel modulator 8 consists of paired pulses 4a, 4b, &c., Fig. 4d. The pulse position translator 14 is adjusted to shift the first of each pair, for example, 4a to a position such as 4a1 such that the new pair 4a1, 4b fit into the gap 42, Fig. 4c, in the combined transmitted pulse train. The phase-shifter 5 is first adjusted to bring pulse 4b into the desired position in the gap. Other multi-channel systems are described in which every transmitted channel includes a pulse position translator, Fig. 5 (not shown), every received channel includes a pulse position translator, Fig. 7 (not shown), and every receiver channel gating pulse circuit includes a pulse position translator, Fig. 9 (not shown). By this means the individual trains of channel pulses in the transmission medium may comprise evenly spaced or paired-off pulses and suitable adjustments can be made at the receiver properly to gate the incoming channels and convert them, if desired, for utilization by demodulators of the shock-excited tuned circuit type operating with paired-off pulses.

Title: Improvements in and relating to electric circuit breakers
IPC: H01H33/98
Filed: 1932-07-28
Abstract: 384,945. Oil-break switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Paul, W. E. ; 2279, Grand Boulevard, Schenectady, New York, U.S.A.) July 28, 1932, No. 21348. Convention date, July 28, 1931. Addition to 371,340. [Class 38 (v).] In a switch of the type described in the parent Specification in which two current breaks in series take place in oil within a pressure-confining-chamber, a pressure-relieving aperture being formed in the wall of the chamber adjacent to one pair of contacts so that the pressure produced by the break at the other pair of contacts forces the oil across the arc adjacent to the' pressure-relieving aperture, according to the present invention the pressure-producing arc is arranged to be of substantially constant length during the initial circuit-opening movement so that an adequate but not excessive pressure is produced within the pressure-confining chamber. As shown in the Figure, the pairs of co-operating contacts consist of fixed springy contacts 6, 7 engaged by wedge-shaped contacts 5 carried by a movable bridging bar, the contacts 5, 7 being adjacent a pressure-relieving aperture 8 formed in the wall of a pressure-confining chamber 3. An auxiliary arcing contact 31 is secured adjacent to the fixed contact 6 so that in opening the arc between contacts 5, 6 is immediately transferred to the arcing contact 31. The arc drawn between the tip 31 and the movable contact 5, which produces pressure forcing oil across the series arc between contacts 5, 7 and out through the aperture 8, remains substantially constant in length during the opening movement until the upper left-hand corner of the contact 5 falls below the out-turned tip of the arcing contact 31. Thus a pressure is maintained which produces an oil blast across the arc at contacts 5, 7 which is directed 'through the aperture 8 so that the arc is normally extinguished before any lengthening of the arc by completion of the opening movement occurs. The opening movement of the circuit-breaker may be retarded at the end of the initial movement in order that the blow-out action may take place by arranging a piston 32 on the bridging bar support 10 passing downwardly through an aperture in the bottom of the pressure-confining chamber. At the end of the initial movement of this member, before any lengthening of the pressure-producing arc occurs, holes 35 in the cylinder 34 are covered by the piston so that oil can only escape through very restricted vents 36. Thus the final contact separation takes place at a retarded rate. The switchoperating mechanism as shown comprises a toggle 20 between the actuating-rod 22 and the pivoted lever 18 for raising i the bridging members, the lever 18 being fitted with an operating roller-18<1> below an insulating crossbar 10 of the bridging member structure and with a return spring 23 for restoring the operating mechanism after release.

Title: Racemization of menthol
IPC: C07C35/12
Filed: 1958-07-07
Abstract: 893,673. Menthol. BOAKE, ROBERTS & CO. Ltd., A. (Glidden Co.), July 7, 1958, No. 21730/58. Class 2 (3). Optically-active steareoisomers of menthol are racemized by heating the given isomer in the presence of hydrogen with a hydrogenationcatalyst, such as copper chromite or catalytic nickel or cobalt, preferably at a temperature between 260‹C. and 280‹C. The process may be used to racemize any of the stereoisomors of menthol, neomenthol, isomenthol and neoisomenthol; and the product is an equilibrium mixture of racemic stereomers regardless of the feed. A particular application is the racemization of d-menthol; for the commercially important l-menthol can then be obtained by resolution of the racemized mixture, and the unwanted disomer can be reconverted to dl-menthol. In Example 3, d-menthol and copper chromite catalyst are charged to a bomb; and hydrogen is then introduced until the pressure reaches 1,300 p.s.i.g. The sealed-bomb is heated at 267‹C.-270‹C., with rocking, for 9 hours. The catalyst is filtered-off from the cooled product; and the optical rotation is found to be 0 degrees. Tests show that the material is truly racemized. Examples 4 and 5 relate to the racemization of d-neomenthol and d-isomenthol, respectively. In Example 6, a mixture of l-menthol and copper chromite is heated at 270‹C.-275‹C. for 4.5 hours under a hydrogen-pressure of 500 p.s.i.g. The product is filtered to remove the catalyst, and then fractionated through an efficient column at 10 mm. pressure. Infra-red analysis and optical examination of the fractions indicate that the product consists of: hydrocarbons (5%), dl-menthone (1% to 2%), dl-neomenthol (18% to 20%), dl-menthol (62% to 64%), dl-neoisomenthol (1 % to 2%) and dl-isomenthol (10% to 12%). The recovered dl-menthol can be resolved by the esterification with d-menthoxyoxyacetic acid, separation of the esters and hydrolysis of the individual esters.

Title: Improvements in or relating to the formation of aliphatic carboxylic acid esters of lignin material
IPC: B29C33/60
Filed: 1943-12-30
Abstract: Lignin esters are produced by treating a solution of lignin in an organic solvent or solvent mixture in the presence of an organic base (which may be the solvent) with an aliphatic carboxylic acid halide or anhydride under anhydrous conditions. In examples, lignin dissolved in pyridine with or without dioxane is heated with acetic anhydride and caproyl, lauroyl, stearoyl and oleyl chlorides respectively.  Up to five hydroxyl groups may be esterified.  The crude ester may be purified by dissolving in a solvent and pouring into a solvent for impurities which is a non-solvent for the ester. Thus, the myristic penta-ester may be dissolved in ether and the solution poured into methanol which precipitates the purified ester; the process, however, converts the pentato the tetra-ester.  A table is given showing the properties of a large number of esters. The esters are useful as internal mould lubricants, especially for powders containing wood fibre, either alone or with resins or modifying agents, and for thermoplastic and thermosetting compositions, such as phenolformaldehyde resin compositions.ALSO:Resinous lignin esters, in which the hydroxy groups of the lignin are esterified with aliphatic monobasic carboxylic acids are used as binders, plasticizers and internal lubricants in moulding compositions, particularly those containing woody material. Examples of lignin esters specified are: the acetate, butyrate, valerate, decanate, laurate, myristate, palmitate, stearate and oleate.
