Filed: 1941-01-02
Abstract: 583,161. Duplex wireless signalling ; filter circuits. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Jan. 2, 1941, No. 49. [Classes 40 (iii) and 40 (v)] Apparatus for preventing transmitted signals from entering the receiving circuit in a duplex short-wave radio system comprises a closed loop PRQS, Fig. 2, of concentric transmission line with the aerial A connected at P, the transmitter T at R, a balancing impedance at Q, and the receiver RE at S. The concentric lines constituting the loop, the aerial feed, and the feed to the balancing impedance have each a characteristic impedance Zo, while the transmitter and receiver are each connected to the loop by quarter-wave lines of characteristic impedance Zo/#2. The loop is so dimensioned that the path PRQ differs from the path PSQ by half a wave-length or an odd multiple thereof; and the points R, S are so chosen that RPS differs from RQS by the same amount. In a constructional example shown in Fig. 3, the concentric lines are formed by inserting axial rods in cylindrical holes 19 drilled in a metal block 1, the connections to the aerial, transmitter, balance and receiver, being made at 2, 3, 4, 5 respectively. The loop thus comprises a rectangle 14, 15, 16, 17 with one side a half-wave and the other a quarter-wave in length. Concentric lines 6, 7, 8 with movable bridges 21, 22, 23 are provided for adjustment; the line 6 for eliminating the effects bf the right-angled junctions, and the lines 7, 8 to serve as a transformer and resonator by which the effective resistance of the carbon plate 13, may be varied. Specification 491,359 is referred to.

Title: Preparation of thermoplastic resin film
Inventor: TANIHARA YOSHIAKI
IPC: B29C48/08
Filed: 1979-01-05
Abstract: PURPOSE:To obtain a film which is used as the magnetic tape base and the like and has a uniform thickness by a method wherein thermoplastic resin is extruded in the form of a film from a die slit, cooled and set on a rotary cooling drum controlled at a constant speed and the film is slackened and taken up from the drum. CONSTITUTION:Thermoplastic resin such as polyethylene, polypropylene, polyethylene terephtalate, etc. is heated and fused, extruded in the form of a film from a die slit, cooled and set on a rotary cooling drum in which the no-load instantaneous rotation fluctuation ratio is controlled within the accuracy of + or -1%. The instantaneous rotation fluctuation ratio is given by a formula. The thickness fluctuation of the film obtained can be removed thereby. In addition, when more effective control for preventing thickness fluctuation is excuted by taking up the film on the cooling drum in a catenary suspension condition in addition to the effect of the constant speed control of the drum, the uniform thickness film will be obtained.

Title: Improvements relating to illuminated circuit diagrams for facilitating the supervision of electrical power or other distribution installations
IPC: H02B15/02
Filed: 1934-01-03
Abstract: 420,629. Electric signalling systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 3, 1934, Nos. 248 and 249. Convention dates, Aug. 10, 1933 and Nov. 18, 1933. [Class 40 (i)] In a mimic diagram of electrical, water, gas &c. distribution systems, only the ends and, if desired, the other important points, e.g. corners and branch-points, of the line sections are brightly illuminated, the remaining parts of the lines being non-illuminated or dimly or intermittently illuminated. The condition of the lines may be indicated by the colour or intensity of the illumination of the ends and other important points, or by flashing lamps. The condition of the remaining parts of the lines may be shown by indicators, or by dim illumination by small lamps or by a small number of normal illuminating lamps. The width of these portions may also be reduced. The transition from the strongly illuminated to the remaining portions of the line may be abrupt, e.g. along a transverse line which is straight or stepped, or there may be a gradual reduction in intensity, and the length or breadth of the illuminated ends may be varied, by screens for example, in accordance with the current or energy in the line. The lamps may be controlled in accordance with either current flow or potential. The end sections of the lines may be illuminated by one or more lamps and an.end section with its lamp casing may form one constructional element of the diagram. Alternately, as described fully below, the lamp illuminating a switch symbol at the end of a line may be used also to illuminate the end of the line. In the mimic diagram for three stations A, B, C, shown in Fig. 1, the busbars 1 are fully illuminated, the line sections 6-11 being illuminated only at their ends e. One form of switch symbol, shown in Fig. 2, comprises a rotatable lamp casing 56 mounted on the panel 51 carrying the line sections 53, 54 which are adapted to be illuminated through apertures 57, 58 controlled by electromagnetically operated shutters 59, 510 in accordance with the condition ot the line.

Title: Plug valve units for extrusion apparatus
IPC: B29C48/694
Filed: 1974-01-03
Abstract: 1455611 Extrusion filter valve unit J ZINK CO Inc 3 Jan 1974 [23 Jan 1973] 00259/74 Heading B5A [Also in Division F2] A plug valve unit for directing flow from a source of extruding material, e.g. plastics, through filter means to an extrusion die, comprises a housing 12, Figs. 1 and 3, having an inlet 20, an outlet 22, flow and return passages 24, 26 for a first filter and flow and return passages 28, 30 for a second filter. The incoming flow is selectively directed to one of the filters and thence to the outlet, by adjustably rotating plug valve means 14, 16 to either of first or second positions. Thus the inoperative filter can be cleaned. The areas of the flow passages through the valve unit are somewhat larger than the area of the upstream end 40 of the inlet so that the area of the flow path through the valve is never less than the area at 40 even during adjustment of the plug means 14, 16 between their first and second positions. Adjustment of the plug means is effected by a reversible worm-drive 50 which drives the plug 14 directly but drives the plug 16 via a lost-motion pin-andslot arrangement 54 and gearing 46, 48. Plug 14 has slits 70 and 80 therein to provide initial communication between the inlet 20 and passages 28, 24 when the plug is being rotated between its first and second positions. Plug 16 has vent passages 64, 62, 60 therein for venting filter return flow from passage 30 or 26 when the slit 70 or 80 has established the initial communication. In an alternative embodiment the plugs 14, 16 are replaced by a single plug 114, Figs. 13 and 14, having a passage 136 for selectively communicating the inlet 120 with filter flow passage 124 or 128, and a pair of further passages 138, 140 axially spaced from the passage 136 for communicating the filter return passages 126, 130 with outlet 122 or with a cleanout passage (not shown). The plug also contains vent slits 150, 152 for co-operation with vents 142, 144, initial connection slits 170, 172, and a decompression slot 154 for the cleanout passages.

Title: Improvements in modulating systems for high frequency electric signalling
IPC: H03C7/02
Filed: 1940-01-05
Abstract: 537,848. Modulating systems. PHILCO RADIO & TELEVISION CORPORATION. Jan. 5, 1940, No. 318. Convention date, Jan. 21, 1939. [Class 40 (v)] In modulating systems of the kind described in Specification 485,959 in which a valve or valves absorb variable amounts of carrier frequency energy in order to generate the modulated wave, the absorber valves are so connected that their grids are excited by the carrier frequency in phase opposition to their plates. The line 14, 16 connecting the carrier source 13 to its load 15 is connected at an intermediate point 11 to a line 10 operating as an impedance inverter and having a length equal to an odd number of quarter-wave lengths. The modulating valves 1 are connected back to back across the other end of the line 10, and the modulating signal is applied in parallel to their grids from a source 8. The cathodes are jointly returned to the centre of a choke 18 across the end 11 of the line 10. A small inductance 7 included in each grid circuit co-acts with the interelectrode capacities 5, 6 to give an induced grid voltage substantially in phase opposition to the carrier voltage imposed on the plates by the line 10 and of a value m times less than the plate voltage, where m is the amplification factor. The necessary inductance 7 may be obtained by varying the size and shape of the grid leads. In order that the absorption load at the point 11 may be a pure resistance, in spite of capacities &c. of the valves 1, a condenser 12 may be connected across the points 11; or the effect of a condenser may be simulated by lengthening the line 14 from the source 13 beyond the normal quarter-wave, and placing inductance coils in series at the end 13. Alternatively, the impedance inverter 16 connecting the points 11 to the load may be modified so that the impedance prevented by the load at the point 11 is such as to neutralize the reactive component presented by the valves 1.

Cellulose cerboxylates, and processes for making films from.-Cellulose aceto-esters containing higher acyl groups are made by treating a partly deacetylated cellulose acetate, particularly an acetone-soluble hydrolyzed cellulose acetate containing 34.5-37.5 per cent of acetyl, with an acid anhydride higher than acetate anhydride, or with an higher organic acid in the presence of a substituted organic acid anhydride, for example, a halogen or methoxy substituted fatty acid anhydride having fewer than 10 carbon atoms, preferably chloracetic anhydride, such substituted anhydride not taking part in the esterification. The esterifying anhydride may be, for example, stearic, propionic, butyric, valeric, heptylic, lauric, myristic, palmitic, cycohexanecarboxylic. crotonic, cinnamic, hydrocinnamic, undecylenic, o-methoxybenzoic and benzoic anhydrides. The esterifying acid may be, for example stearic, propionic, butyric, valeric, caproic, heptylic, caprylic, pelargonic, capric, lauric, myristic, palmitic, oleic, crotonic, undecylenic, cyclohexanecarboxylic, benzoic, omethoxybenzoic, chlorbenzoic, acetylsalicyclic, phenylacetic, hydrocinnamic and cinnamic acids; and halogen substituted higher organic acids, such as, dibrom-, dichlor- or tetrachlor-stearic acids, may also be used, producing the corresponding cellulose acetoclilor- or brom-stearates. As the esterification-impelling anhydride, there may be employed mono-, di-, or tri-chlor. or brom-acetic, propionic, or butyric, anhydride, and also methoxyacetic anhydride. The esterification is carried out in the presence of chloracetic acid, preferably with the aid of an esterfication catalyst such as magnesium perchlorate. Esters containing acyl groups having an ethylenic bond may be halogenated. From solutions of the esters there are prepared transparent flexible films, which in the case of esters containing halogenated acyl groups, are distinguished by their non-inflammability.

Title: Improvements in or relating to the manufacture of pantetheine-4-phosphate and pantethine-4-phosphate
Inventor: BADDILEY JAMES
IPC: C07F9/09
Filed: 1953-01-09
Abstract: A product containing pantethine-41-phosphate and/or pantetheine-41-phosphate is made by treating pantethine with a diaralkyl halogenophosphonate under anhydrous conditions in the presence of a tertiary organic base such as a member of the pyridine series, preferably at -40 DEG  C. to 0 DEG  C., and treating the pantethine-41-diaralkyl phosphate formed, with a hydrogenolysis reagent such as an alkali metal in liquid ammonia followed by treatment with a reducing agent if required, to effect at least partial disulphide-to-thiol reduction.  Suitably the hydrogenolysis reagent is used to effect both dearalkylation and also the disulphide-to-thiol reduction.  The product may be purified by successive barium salt precipitation, silver salt precipitation and finally repricipitation as the barium salt.  The pantethine used as a starting material may be obtained by oxidizing pantetheine, preferably by passing oxygen through a solution of pantetheine in a basic solvent which may for example consist at least in part of a tertiary base of the pyridine series or an alkylene diamine such as ethylene diamine which has cupric hydroxide associated with it. Preferably the starting materials and products are in the D(+) form. In examples (1) oxygen is passed into a solution of pantetheine in pyridine, the product is treated with dibenzylchlorophosphonate followed by reduction with sodium in liquid ammonia and the resulting pantethine - 41 - phosphate and pantetheine-41-phosphate are separated as barium salts and are purified by successive reprecipitation as the silver salts and barium salts; (2) pantetheine is treated with oxygen in ethylene diamine containing cupric hydroxide and the resulting pantethine is treated as in (1).
