Patent GB-563834-A (GB)
Title: Imbibition printing
IPC: G03C7/25
Filed: 1943-05-11
Abstract: 563,834. Photographic imbibition printing. TECHNICOLOR MOTION PICTURE CORPORATION. May 11, 1943, No. 7492. Convention date, Oct. 31, 1942. Drawings to Specification. [Class 98 (ii)] Before printing a monochrome or multicolour still or kinematograph picture by imbibition from relief or flat, differentially-hardened matrices on a dye-absorptive blank, the blank is differentially hardened in inverse ratio to the density of the colouring to be printed in the picture area in order to restrict lateral diffusion of the subsequently printed dye. The blank may be a gelatino-silver halide emulsion layer which is first photographically printed from a black and white record, or one of a set of colour component records, of the picture, is then developed with a hardening developer followed by a non-hardening bleach, or with a non- hardening developer followed by a hardening bleach, and'is finally fixed before printing from the imbibition matrix or matrices. If, in the case of a multicolour picture, a grey key print also is desired, after the bleaching step and before fixing, the residual halide in the layer is exposed to light and developed to a silver positive. In addition to the differential hardening of the blank, it may be uniformly hardened, e.g. as described in Specification 484,411. In one example of the production of a multicolour picture without a grey key, the colour component record selected for the differential hardening step is a red aspect positive ; in another, produced with a grey key, the component selected is a green aspect positive. Any staining of the blank resulting from the treatments prior to imbibition printing may be removed by bleaching as with acid permanganate followed by bisulphite.

Title: Improvements relating to electrical control circuits for vibratory feeders
Inventor: HAMMERTON EDWARD
IPC: B65G27/00
Filed: 1967-02-17
Abstract: 1,219,764. Automatic control of vibratory feeders. LOCKER INDUSTRIES Ltd. Feb. 9, 1968 [Feb.17, 1967 J, No. 7654/67. Heading G3R. A parameter of a material being conveyed by a vibratory feeder is maintained at a desired value by varying the amplitude of the A. C. supply to the feeder in accordance with a control signal applied to a transistor which regulates the D.C. in the control winding of a saturable reactor whose A.C. winding is connected to the primary winding of a transformer having a secondary winding connected to a circuit for modulating the feeder supply. The control signal (representative of the parameter error) is applied to a transistor TR3 forming part of a high gain amplifier TR3 - TR7, R9 - R12 controlling the D. C. supply to a saturable reactor TD1 connected to the primary winding of a transformer T1. One secondary winding of the latter supplies a bridge rectifier MR1 which increases the positive half of the A. C. supply from input terminals L1, L2 for application to the feeder terminals V1, V2. Another secondary winding supplies a bridge rectifier MR2 controlling transistors TR1, TR2 of which the former conducts the negative half of the A. C. supply L1, L2 and is controlled to complement the action of the rectifier MR1. Thus the control signal produces a modulation of the A. C. supply L1, L2 to vary the D.C. component thereof and hence the amplitude of oscillation of the feeder which is of conventional type, Fig. 1 (not shown). Stability of the control system is provided by a negative feedback loop comprising a saturable reactor TD2 whose control winding shunts the bridge MR1 and whose A.C. winding varies the output of a bridge rectifier MR3 connected to the control signal via components XL1, C1, R7 and R8. The control system may provide a constant rate of feed of the conveyed material according to the weight being discharged from the feeder or, if the conveyed material is a fuel, may control the rate of feed to maintain constant the ash content of the fuel passing a particular point at any time.

Abstract: 789,110. Feeding-appliances for animals. NEWMAN, L. March 12, 1956 [March 15, 1955], No. 7662/56. Class 5(2). A dry feed dispensing apparatus comprises a feed tray 3 adjustably suspended on a rod 5 beneath the outlet of a hopper 1 and supporting a conical feed flow control member 7 which slidably engages the rod 5 at its apex. A member 11 upstanding from the feed tray 3 bears at its upper edge a pin 12 which is slidably engaged in a slot 13 in a member 14 upstanding from a tiltable platform 17. The exertion of pressure on the platform 17 causes the platform and the member 14 to rock, this in turn imparting to the member 11, the feed tray 3 and the member 7 a reciprocal, lateral, arcuate motion about the rod 5, such movement causing the dry feed to flow into the feed tray.
Patent GB-913350-A (GB)
Title: Process for the acylation of organic compounds
IPC: C08B3/00
Filed: 1959-03-05
Abstract: Organic compounds which contain hydroxy or amino groups (primary or secondary) are acylated with an acyl-urethane containing at least one group of the general formula -CO-NH-CO-XR, wherein X represents oxygen or sulphur and R is a hydrocarbon group which may have an alkoxy or halogen substituent.  This acylating agent is useful in bringing about cross-linking in compounds of high molecular weight, such as polyvinyl alcohol, cellulose, a polyglycol, a polyamine or a polyamide.  In Example 2, N,N1-adipyl-bis-carbamic acid-isopropyl-ester is heated at 160 DEG C. with neopentyl glycol. The reaction-product, on cooling, is a resinous mass.  In Example 3, the 2-amyl ester of N,N1-adipyl-bis-carbamic acid is heated with hexamethylene diamine.  The solid product can be drawn out into filaments if the operation is carried out quickly. In Example 4, a solution of cellulose acetate in acetone is mixed with the 2-chlorophenyl ester of N,N1-oxalyl-bis-carbamic acid.  The resulting mixture is cast into a film and heated above 130 DEG C.  The resultant film is insoluble in acetone.  In Example 8, films are obtained by reacting the acrylyl urethane. CH2=CH,CO,NH,CO,O,CH2,CH2,OCH 3 with polyvinyl alcohol.  The Specification states that bis-acyl-urethanes may be reacted with the polyamides obtained by condensing an oxalic ester with a mixture of dipropylenetriamine and N-methyl-dipropylenetriamine.ALSO:The invention comprises a process for the acylation of organic compounds, which contain hydroxyl or primary or secondary amino groups, by reacting the given organic compound with a compound which contains at least one group of the general formula -CO-NH-CO-XR wherein X represents oxygen or sulphur, and R represents a hydrocarbon radical, which may have an alkoxy or halogen substituent.  Typical examples of specified acylating agents may be prepared by reacting the acid chloride of isobutyric acid, diglycolic acid, isophthalic acid or trimesic acid with methyl carbamate, b -methoxyethyl carbamate, or 2-chlorophenyl carbamate.  The acylating agents may also b prepared by reacting an acylisocyanate with an alcohol, mercaptan or phenol. In an example, 4-chlorobenzyl alcohol is heated to 165 DEG C. with N,N1-adipyl-bis-carbamic acid isopropyl ester in the presence of o-dichlorobenzene as solvent.  Isopropanol is evolved; and N,N1-adipyl-bis-carbamic acid-4-chlorobenzyl ester crystallizes out on cooling.  Mention is made to the S-methyl ester of N,N1-adipyl-bis-carbamic acid.  The Specification also relates to the production and modification of synthetic polymers by reacting the acylating agents with neopenyl glycol, hexamethylene diamine, acetyl cellulose and polyvinyl alcohol (see Group IV(a)).

Title: Improvements in or relating to method and device for the remote-control of autorotative missiles
IPC: G01S3/788
Filed: 1964-02-26
Abstract: 1,057,591. Controlling guided missiles. SOC. ANON. DE TELECOMMUNICATIONS. Feb. 26, 1964 [Feb. 27, 1963], No. 7903/64. Heading B7G. [Also in Divisions G3 and H4] Relates to a system incorporating an automatically rotating missile (A, Fig. 1) in which system a photo-electric direction finder at a ground station (B) determines the departure of the missile from a reference axis and transmits " command " signals to the missile to direct the latter on to the reference axis. According to the present invention the polar co-ordinates of the missile relative to the reference axis are cyclically detected in synchronism with the rotation of the missile utilizing signals sent by the missile and the command signals are sent to the missile at instants corresponding to a predetermined angular position of the missile relative to its rotational axis. In the embodiment the reference axis is the optical axis (X X) which may be that pointing to a target. Infrared radiation from the missile is imaged on to an obturator (6, Figs. 1, 2) which is rotated by cranks (7, 8) driven by a motor (14), the centre of the obturator following a path coinciding with the edge of a circular window (4). The amplified output of a photo-cell (2) is fed via an amplitude limiter to a frequency discriminator (18). A bridged-T phase equalizer (20) is provided, controlled by a torque motor (22) as a function of the angular velocity of the missile about its axis (Fig. 5). The motor (14) also drives signal generators (26 and 27). the latter producing an output frequency which is an integral multiple of that of the former which feeds a frequency discriminator (28) controlling the torque motor (22), whereby time lags are compensated. The output of a signal generator (26) is fed to trigger circuits (32a, 32b), the other inputs to which are the synchronizing signal emitted by the missile. The trigger circuit outputs are mixed and fed to the obturator motor (14). In the initial stages of missile motion its rotational velocity may vary; a temporary programmed control (36) is provided such that the speed of the obturator motor (14) follows the variations in the rotational speed of the missile. To prevent jamming or to increase signal/noise ratio the missile may transmit to the photo-cell signals modulated at a frequency other than that given by the obturator (6): in this event an amplifier and detector are inserted at the output of an amplifier (15). The command signals transmitted to the missile may be square-wave signals.
