Title: Improvements in or relating to closed loop servo control systems
Inventor: WILLIAMS FREDERIC CALLAND
IPC: G05B11/50
Filed: 1948-05-14
Abstract: 647,983. Electric follow-up systems. MINISTER OF SUPPLY, and ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 14, 1948, No. 13241. [Class 40 (i)] In a closed loop servo-control system the amplifying channel and/or the feed-back channel comprises at least two parallel paths each having different and overlapping frequency/gain or frequency/phase-shift characteristics, the frequency characteristics of the respective paths having, at their overlapping regions, complementary forms so that the combined effect of the two paths is to give a substantially uniform response over a desired frequency range. Preferably a D.C. amplifier A, Fig. 1, e.g. a magnetic amplifier, is used in parallel with a wide-band A.C. amplifier B, filters F1, F2, being series-connected with the respective amplifiers to render the overlapping portions A1, B1, of their frequency/gain characteristics, Fig. 2, complementary, giving a combined uniform gain response as at C from zero frequency. In an arrangement for stabilizing a rolling platform e.g., a rate-measuring gyroscope may be employed to provide a velocity feed-back component for the L.F. response, the velocity component responding to H.F. being derived from a tacho-generator driven by the servomotor. The two may be used together with the necessary conjugate filters to provide a feed-back signal having as above described an overall uniform frequency characteristic.

Filed: 1933-10-09
Abstract: 431,676. Gas fires. HELPS, G., Manor Court, Nuneaton, Warwickshire. Oct. 9, 1933, No. 13341. [Class 126] In incandescent gas fires the radiant material is carried by a grid-like structure formed of spaced bars carried by, but not integral with, the fire back or base, or by a supporting frame ; alternatively, in the case of tubular radiants these may be supported on " cobble " refractory material, resting on the fire-back. In either case, an increased surface exposed to the flames is provided without a proportionate increase in the heat conduction through the fire-back. A number of different forms of fire are described, Fig. 1 showing a construction in which tubular radiants 1 rest on cobble material 2 carried by a metal base plate 6, further cobble material being placed over the radiants. Figs. 2 and 4 show a fire having a refractory back 6<11> the front of which is channelled to form ribs 7 which are notched to carry spaced bars 8 between which and a front metal guard 9 is carried cobble fuel 2, this being heated by a burner the jets of which are arranged in the channels of the back. Alternatively, the face of the back may be plain, vertical fillets taking the place of the ribs 7 being arranged in front of it. Figs. 19 and 20 show a fire in which round bars 11 support cobble fuel 12 which is preferably curved to engage them. The gas jets 13 are delivered between the bars, which are shown as resting on cobble fuel. Fig. 29 shows a fire comprising cobble fuel 2 resting on an inclined grid of bars 11 carried in a frame 16 and heated by a burner 5. In a somewhat similar fire, a further layer of cobbles is supported on an inclined fire-brick below the grid, the flames passing up the space between the two layers. The bars forming the grid may be secured together as a single unit, and they may be of other than rectangular or circular section, a number of alternative forms being illustrated. In some cases a structure supporting cobble fuel may be built of a number of stepped layers of bars, as shown in Fig. 23.
Patent GB-456070-A (GB)
Title: Improvements in the manufacture and production of diamides and imides of dicarboxylic acids
IPC: C07C233/00
Filed: 1935-05-07
Abstract: Polynuclear compounds containing at least one aromatic hydrocarbon nucleus (i.e. aromatic hydrocarbons containing at least two nuclei, or heterocyclic compounds containing at least one aromatic hydrocarbon nucleus and a heterocyclic nucleus), are treated with at least two molecular proportions of carbamyl chloride or an alkylcarbamyl chloride in the presence of at least two molecular proportions of a catalyst of the Friedel-Craft type. Two carboxylic amide groups are thus introduced into the polynuclear compound; if, however, the carboxylic amide groups enter the molecule in peri-positions, dicarboxylic imides may be obtained.  The carbamyl chloride and the catalyst may be taken separately, or use may be made of the molecular compounds obtainable therefrom as described in Specification 449,100. Examples are given in which, by reaction with carbamyl chloride and aluminium chloride, or the molecular compound obtainable therefrom, (1) diphenyl yields diphenyl-4, 4<1>-dicarboxylic acid diamide, from which the free acid may be obtained by acid saponification; (2) acenaphthene yields acenaphthene-5 : 6-dicarboxylic acid imide, from which the free acid is obtainable by saponification; the acid yields the anhydride when heated; (3) fluorene yields a fluorenedicarboxylic acid diamide; (4) stilbene yields a stilbenedicarboxylic acid diamide, from which the free acid is obtainable by boiling with caustic soda solution; (5) diphenylene oxide similarly yields a diamide from which the free acid is obtainable by alkaline saponification; (6)--(10) chrysene, carbazole, pyrene, fluoranthene and brasane are converted into carboxylic acid diamides.  The treatment of diphenylbenzenes is mentioned.  Specification 448,788 also is referred to.  A sample has been furnished under Sect. 2 (5), of diphenyl-4 : 4<1>-dicarboxylic acid di(methylamide), prepared from diphenyl and methylcarbamyl chloride.

Patent GB-756042-A (GB)
Title: Process for preparing optically active intermediates for the synthesis of chloramphenicol
Filed: 1953-05-14
Abstract: DL - Threo - 1 - (p - nitrophenyl) - 2 - aminopropane-1 : 3-diol is resolved into its optically active components by dissolving the racemic base in water at elevated temperature (preferably not above 80 DEG  C.), the amount dissolved being sufficient to produce a non-crystallizing solution which is supersaturated at room temperature, dissolving in the said solution, while at elevated temperature, an amount of 2-12 per cent, based on the weight of the racemic base, of one of the enantiomorphic components, cooling the solution to about room temperature (e.g. 20 DEG  C. or below), and removing the optically active component which separates (in an amount exceeding that added to the hot solution) from the mother liquor. The latter (now containing excess of the other enantiomorph) may be reheated and a quantity of the racemic base dissolved therein, whereby, on again cooling, a quantity of the other enantiomorph crystallizes out and is separated, the process being capable of being repeated indefinitely with alternate separation of the D- and L-isomers. In a modification of the process, instead of the racemic base alone there is used a mixture thereof with a salt thereof of higher solubility, which mixture may be formed in situ by the addition of an acid (e.g. a halogen hydracid) to the solution of the base or by the addition of an alkaline substance to a solution of a highly soluble salt of the base.  In examples: (1) DL-base and 10 per cent of D-base are dissolved in water at 80 DEG  C., the solution is cooled to 20 DEG  C., the D-base which precipitates is separated off, the mother liquor is reheated to 80 DEG  C. and more DL-base is added, the solution is cooled to precipitate L-base, and so on; (2) DL-base and about 7.5 per cent of L-base are dissolved in less than an equivalent amount of 2N-hydrochloric acid at 45-50 DEG  C., the solution is cooled to 25-27 DEG  C., the L-base which precipitates is filtered off, more DL-base is added to the filtrate, which is then reheated and cooled to precipitate D-base, and so on; (3) DL-base hydrochloride and about 7.5 mol. per cent of D-base are dissolved in water at 50-55 DEG  C., sufficient caustic soda solution is added to liberate about 20 per cent of DL-base, the solution is cooled to 25-27 DEG  C. and precipitated D-base filtered off, and more DL-base hydrochloride and an equivalent amount of caustic soda solution are added to the filtrate, which is reheated and cooled to precipitate L-base, and so on.  Specification 652,280 is referred to.

Title: Improvements in or relating to machines for performing edge setting or like burnishing operations on the margins of boot or shoe bottoms
IPC: A43D95/24
Filed: 1935-05-09
Abstract: <PICT:0456364/III/1> <PICT:0456364/III/2> <PICT:0456364/III/3> <PICT:0456364/III/4> In a machine for performing edge setting or like burnishing operations on the margins of shoe bottoms, finishing medium is applied intermittently in successive small quantities to spaced portions around the sole, while the shoe is being operated by the burnishing tool.  Such a machine, in which the work is moved automatically past the tool, is shown in the drawings.  The shoe is clamped in a jack 2, which is automatically swung to-and-fro, about a shaft 4, a chosen number of times, to cause the edge of the sole to traverse past the vibrating setting iron 1, more than once.  The vibrating setting iron 1 is carried by a movable head 3 which carries also an electrically-heated wax-container 5 within which is an axially slidable plunger 9.  This plunger, when operated by the cable 17, ejects melted wax through the pipe 29 on to the sole edge to the rear of the setting iron 1.  The opposite end of the cable 17 is actuated by a lever 31 pivoted at 33 and intermittently rocked by cams 45 adjustably spaced on a rotatable disc 41.  This disc is arranged to be rotated during the second traverse only of the sole past the setting iron, and during that traverse a number of applications of wax to spaced portions of the sole edge, equal to the number of cams on the disc 41, is made.  A sleeve 53 is oscillated, during each complete traverse of the sole past the setting iron, by a chain 47, connected to a reciprocating hydraulic slide 49 and to a cam controlling the movements of the jack, but rotary movement is conveyed from the sleeve 53 to the disc 41 only during the second traverse of the sole, when the hooked end 57 of the lever 55, actuated by the finger 71, ratchet wheel 69 and cam disc 63, engages <PICT:0456364/III/5> the single notch 58 in a depending neck of the disc 41.  A freely rotatable collar 76, recessed at 77 to engage a pin 79 fast on the bracket 67, together with a nose 81 and an engaging lug 83, ensure that the disc 48 will commence to rotate, and the application of wax to the sole edge will commence, immediately after the commencement of the second half of the second traverse, whatever may be the size of the sole.  During the third traverse of the sole past the setting iron, the end 57 of the lever 55 is held free from the notch 58, so that no wax is applied.  When the machine has been thrown out of operation, the cam disc 63 may be restored to its initial position, on restarting the machine, by means of the cable-operated pivoted arm 78 carrying a pawl 85 to engage one or other of the pins 82 on the ratchet wheel 69.  Means may be provided for adjusting the height of the end of the pipe 29.  A slightly modified form of machine is described in the Provisional Specification.  Specifications 14696/08, [Class 17], 343,077; and 408,940, [Group VII], are referred to.
