Patent GB-1046526-A (GB)
Title: Process for the production of copolyether esters
IPC: C08G63/78
Filed: 1964-01-30
Abstract: A copolyester polyether is produced by reacting an oligomer mixture derived from terephthalic acid, a glycol and a hydroxyaromatic carboxylic acid successively with terephthalic acid and a glycol-ester or glycolether of a hydroxyaromatic carboxylic acid or a mixture thereof and polymerizing the product. All reactions are conducted at at least 220 DEG  C. Glycols specified are linear alkylene glycols of 2-10 carbon atoms, e.g. ethylene glycol.  Free glycol or hydroxy-acid may be added with the glycol-ester or glycol-ether.  Hydroxy aromatic carboxylic acids specified are p-hydroxybenzoic acid and its chloro and methyl derivatives and vanillic acid.  The oligomer mixture may comprise a mixture of p-b -hydroxyethoxybenzoic acid b -hydroxyethyl ester and an oligomer of 3 ethylene glycol units condensed with 2 terephthalic acid units.  The process may be a batch or continuous process.  In continuous operation the oligomer mixture is allowed to flow down column 1.  The terephthalic acid is introduced from conveyor 4 and the glycol or glycol ester of ether via valve 5.  A polycondensation catalyst, e.g. antimony or manganese acetates, sulphonic acids or compounds of amphoteric elements, e.g. B, Be, Al, Zn, Pb, Sn, Fe, Ti, As or Co may be added with the terephthalic acid and a stabilizer, e.g. triphenyl phosphate or other metal alkyl, or aryl phosphate or phosphite or a phosphorus acid may be added with the glycol or glycol ester or ether. An inert gas enters at 6.  The eliminated water escapes via fractionating column 2.  From the bottom of the column part of the material is returned to the top by pump 8a and the remainder is removed to reactor 10 for polycondensation at 220-260 DEG  C./< 0.1 mm. Hg. It is sprayed on to revolving drum 14 and when sufficiently polymerized is removed by scraper 16 and conveyers 17 and 18.

Title: Improvements in and relating to the televising of motion picture film
Inventor: LORD ARTHUR VALENTINE
IPC: H04N3/40
Filed: 1957-02-06
Abstract: 821,163. Television. BRITISH BROADCASTING CORPORATION. Jan. 28, 1958 [Feb. 6, 1957], No. 4158/57. Class 40 (3). Each frame of intermittently moving film 7 is scanned in two different fields simultaneously by the use of duplicate assemblies 1, 11 and 2, 12 of a flying- spot scanner and photo-electric cell, the lights from which are distinguished by the use of coloured or polarizing filters 3, 13 and 4, 14, and storage means 17 is provided for delaying one of the resulting signals so that it is interlaced in time with respect to the other. Conventional correcting circuits 15 and 16 are provided and the two signals are combined in a common output 18. The arrangement is employed for interlaced scanning of the film and has the advantage that the flying-spot scanners are required to operate only in alternate field periods so allowing an adequate time interval for the film pull-down operation. According to one method of operation, the rasters produced on the screens of scanners 1 and 2 are arranged to be interlaced by the use of line scanning waves which are displaced in phase by the duration of half a line. The delay provided by store 17 is then arranged to be equal to one field period. According to another method of operation, the rasters produced on the screens are arranged to be identical, but the tubes are disposed so as to project images on to the film which are displaced relatively by one half line pitch. In this case store 17 provides a delay equal to one field period plus or minus (according to the sense of the displacement of the rasters) half a line period. A system for producing scan trigger pulses displaced in phase by half a line period for carrying out the first method is described with reference to Fig. 2 (not shown). The arrangement disclosed in Specification 817,576 and an ultrasonic delay line are referred to in connection with store 17.

Title: Improvements in and relating to Controlling Mechanism for Electric Motors Operating Cranes, Lifts and the like.
IPC: B66B1/48
Filed: 1916-03-24
Abstract: 104,407. British Thomson-Houston Co. and Wise, W. L. March 24, 1916. Systems for travelling a fixed distance or number of revolutions; controllers with auxiliary switches.-Controlling-apparatus of the type described in Specification 11926/07 for electric motors operating cranes, lifts, etc., is provided with means whereby the motor may be reversed after it has tripped the limit switch. The contacts f', f2, Fig. 1, of two relays r', r<2> are arranged in parallel to the limit switches c, d respectively, and the windings are connected across the motor as shown. When the controller is moved to a running position, the relay with contacts parallel to the particular limit switch to be operated is opened. When the limit switch is operated, the main contactor e is opened. This allows the relay contacts to close, and the controller may then be moved to reverse the motor, the circuit of the contactor e being maintained through the relay contacts. If the controller is moved forward again after the limit switch has been operated, the relay is lifted to open the contactor e. In a modification, each relay has two windings which oppose each other when the relay is to remain closed, but aid each other when the relay is to be lifted. When a three-phase motor is used, the windings of the relays are associated with the two phases which are interchanged to obtain reversal. This arrangement may be modified, as shown in Fig. 4, by the introduction of a third relay r<3>, which controls contacts in the circuit of the windings of the relays r<1>, r<2> so that these windings cannot be energized through the third phase of the motor. In another modification, a single relay is used in combination with a limit switch having one arm movable between two fixed contacts.

Title: Electrical binary divider
IPC: G06F7/535
Filed: 1958-02-11
Abstract: 860,852. Digital electric calculating-apparatus. MONROE CALCULATING MACHINE CO. Feb. 11, 1958 [Feb. 11, 1957], No. 4497/58. Class 106 (1). A digital electrical calculating-circuit is arranged to provide a representation in binary form of the integral part of the number of times a divisor represented by a serial binary pulse train is contained in a dividend represented by a serial binary pulse train. As shown, an input A is normally applied directly from the input 1 to an adder/subtractor 10, which feeds a second adder/subtractor 15 whose output E is fed back via delays 18, 19 of F and G pulse times to the adder/subtractors 10, 15. Thus the output E is given in terms of A by the relation E=A +A(1Œ2<SP>F</SP>Œ2<SP>G</SP>), and by choosing suitable values of F and G and choosing suitable combinations of plus and minus signs by controlling the adder/ subtractors accordingly, a large number of divisors can be represented. For negative divisors the output may be complemented by an inverter 30 in response to a signal on a line 27. To allow for dividends not being integral multiples of divisors, the dividend K represented in a suitable word time comprising J pulse times, is applied twice to the input 11, the first application being possibly in complemented form so that N=(2<SP>J</SP>Œ1)K is effectively applied, J being chosen so that 2<SP>J</SP>Œ1 is an integral multiple of the divisor. The required form of the input to the adder/subtractor 10 is obtained by applying to the adder/subtractor the input at 1 either directly or after inversion by an inverter 29 which may be a triode amplifier and also after a delay of J pulse time by a delay 21 which may be a shifting register or mercury delay line. The desired output is obtained at 2 during the second word time.
