Abstract: 1,189,704. Printing processes. INTERNATIONAL BUSINESS MACHINES CORP. 26 June, 1967 [30 June, 1966], No. 29307/67. Heading B6C. [Also in Division G2] A thermographic process comprises contacting an original containing a volatile material with a first receptor sheet which is infra-red absorptive, heating the assembly to transfer the volatile material image-wise to the receptor sheet, contacting the receptor sheet with a second receptor sheet and exposing to infra-red radiation to re-transfer the material and then if necessary, developing the latent image, to produce a right-reading visible image of the original. The volatile material may be an alkanolamine, or a hydrogenated terphenyl which is developed by applying a powder developer to the final receptor sheet. However, if the final receptor sheet is a two-component diazotype sheet and the volatile material is an alkanolamine a visible image is produced directly. The first receptor sheet preferably contains carbon black as the infra-red absorbent pigment and has a machine glazed surface which receives the volatile material.

Title: Fire detection systems
IPC: A62C3/08
Filed: 1961-08-14
Abstract: 961,145. Temperature alarm devices. J. E. LINDBERG. Aug. 14, 1961 [Aug. 17, 1960], No. 29312/61. Heading G4N. A fire alarm system particularly for use in aeroplanes comprises a series circuit including warning lamps, 27, 28 arranged to light only a finite time after the occurrence of an alarm condition, a temperature detector of the type disclosed in Specification 961,143 including a normally open pressure operated switch 11 and the power supply in the form of a transformer secondary 16, the arrangement being that under normal conditions the resistance 12 connected across switch 11 is included in the series circuit and limits the current in the circuit to a value less than necessary to light lamps 27, 28 but on the temperature exceeding a fixed level, switch 11 is closed thereby shortcircuiting resistance 12 so that the current through the circuit becomes sufficient to light the lamps. A number of detectors including pressure sensitive switches may be connected in parallel (Fig. 2, not shown). The circuit may be immersed in an electrolyte e.g. salt water. It is stated that in this case short circuiting of terminals 30, 31 and false alarms due to this are prevented by the "passivation" i.e. the rapid build up of a high resistance film or the forming of gas bubbles on the terminals due to the relatively large current across the short. By connecting switch contact 38 to either of contacts 34, 37 the high and low sides of the circuit respectively will be earthed purposely and the lamps will light if the low and high sides of the circuits are earthed respectively.

Title: Process for the continuous solution polymerization of 1,3-butadiene
Inventor: AMERONGEN GERRIT JAN VAN
IPC: C08F36/06
Filed: 1968-06-20
Abstract: 1,204,764. Polybutadiene. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 18 June, 1969 [20 June, 1968], No. 29380/68. Headings C3G and C3P. 1,3-Butadiene is polymerized continuously in a homogeneous reaction mixture in a reactor in the presence of one or more hydrocarbon solvents and a catalyst formed from a hydrocarbon soluble organic cobalt compound and a hydrocarbylaluminium chloride compound, the cobalt concentration in the reactor being less than 5 p.p.m. by weight of the reaction mixture, by a process comprising adding the cobaltcontaining compound to one or more liquid streams, providing that all streams entering the reactor provide an average cobalt concentration which is at least one times the cobalt concentration in the reactor, the cobalt concentration in any cobalt stream when entering the reactor is less than 4 times the cobalt concentration in the reactor and that the cobalt-containing compound and the aluminium-containing compound are not added to one and the same stream having a 1,3-butadiene content of more than 1% by weight. The two catalyst components are preferably fed to one or more liquid solvent recycle streams and are preferably cobalt acetylacetonate and a hydrocarbylaluminium chloride compound which has been prepared by reacting a dihydrocarbylaluminium monochloride with water. In a preferred embodiment at least two liquid recycle streams are applied (A) benzene, having a 1,3-butadiene content of not more than 1 % w. and (B) butene, having at least 90% of the 1,3-butadiene feed and at least 90% of the unconverted 1,3- butadiene. In the examples 1,3-butadiene is continuously polymerized in a mixed solvent of benzene and butene in the presence of a catalyst comprising cobalt (II) acetylacetonate and a reaction product of diethylaluminium chloride. The polymerization is terminated by the addition of ethanol and as an anti-oxidant, a phenol. The mixture is steam stripped to remove the polymer from the stripped off solvent mixture and unreacted monomer, the stripped off mixture being purified by distillation to produce a larger stream of butene-1 and butadiene, and a smaller stream of benzene. These streams are recycled to the reactor, the benzene stream being mixed with a water containing stock solution and diethylaluminium chloride, and the butene stream, which contained butadiene feed, being mixed with the cobalt containing catalyst components. The resultant polymer, which has a high cis,1,4 content, is further polymerized by dissolving in styrene and further polymerizing with lauroyl peroxide to form a high impact polystyrene. A mixture of 1,3- butadiene and less than 10% by weight of isoprene may also be polymerized by the above described process. A solution of 6 % w. butadiene rubber, obtained by the above process, and 0.1% w. of lauroyl peroxide as initiator, in styrene was prepolymerized in a N 2  atmosphere at 90‹ C. and postpolymerized at 180‹ C. to produce a high impact polystyrene.

Title: Improvements in or relating to apparatus for controlling aircraft
IPC: G05D1/08
Filed: 1948-11-12
Abstract: 698,038. Automatic control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 12, 1948 [Dec. 11, 1947], No. 29411/48. Drawings to Specification. Class 38 (iv). The subject-matter of this Specification is in the main identical with that of Specification 698,033, but involves the following modifications : (a) Operation of the hand wheel to initiate turn of the craft moves the slider of a first potentiometer from a central position. The slider of a second potentiometer is then driven into positional correspondence with the slider of the first potentiometer by a reversible servomotor controlled through a polarized differential relay by the voltage between the sliders of the two potentiometers. A voltage thus appears initially between the sliders of the two potentiometers which serves to bias the bank gyro and produce banking suited to the turn. This effect, however, disappears as the potentiometers reach positional agreement and a voltage then appears between the slider of the second potentiometer and its centre-tap which serves to bias the turn and pitch gyros and produce the turn and the necessary up elevator. A negative feed-back dependent on servomotor velocity is applied to separate windings of the polarized relay from the output of a bridge circuit associated with the armature of the servomotor. (b) During straight flight the directional gyro, instead of controlling bias of the rate of turn gyro, controls bias of the bank gyro and the energization of further windings of the polarized relay at (a) above. The effect of the latter upon deviation from course results in operation of the servomotor, thereby producing a voltage between the slider of the second potentiometer and its centre-tap to bias the turn and pitch gyros in the appropriate sense. (c) A switch which is opened when the second potentiometer at (a) above moves from its central position delays the energization of the electromagnet which locks the rotor of the receiver of the synchronous transmission between the directional gyro and the bank gyro during straight flight. The craft is thus allowed time to reach a stable condition after a turn. Specifications 698,032, 698,034 and 698,037 also are referred to.

Title: Improvements in the application of labels to containers
Inventor: ROSE ALFRED GERMAN
IPC: B65C3/20
Filed: 1954-10-13
Abstract: 805,481. Labelling machines. ROSE BROS. (GAINSBOROUGH), Ltd. Oct. 12, 1955 [Oct. 13, 1954], No. 29438/54. Class 73 Labels are applied to the closures of bottles 11, or other articles, by feeding the bottles in spaced succession along a rectilinear path to and through the labelapplying station in timed relationship with the movement of a rotatable pick-up member 21 adapted to receive a succession of labels. Each label has its outer surface rendered adhesive whilst held on the surface of the pick-up member and is positioned on the bottle with portions extending laterally, these portions being folded over by the application of resilient pressure, there being substantially no relative movement between the bottle and pressure applying means, in the direction of movement of the bottle, during the application of such pressure. The apparatus shown is similar in many respects to that disclosed in Specification 783,090 in that it comprises two spiders 18,19 mounted on a driven shaft 14, the spider carrying rack member 22 which, by means of a fixed cam 28, oscillates to provide the necessary movements of pick-up members '21 pivotally connected to the spider 18. As in the earlier Specification, the pick-up members are connected to a suction pipe 58 via hoses 52 and members 53, 54,  whereby they pick up labels from an oscillating magazine 62, apply them to a gumming device 63, and finally apply them to the closures of bottles 11 on a moving conveyer 12. As a member 21 and a bottle reach the label-applying station the cam 28 causes the member to press a label on to the bottle. The overhanging ends of the label pass between a pair of segmental brushes 66 which rotate to sweep the ends downwardly into contact with the bottles. During this sweeping action a cam-operated arm 68 connected to the brush-shaft 67 causes the brushes to move at substantially the same speed as the bottles as defined above. The machine may be combined with one, such as that described in Specification 783,090, for applying neck and body labels to the bottles.
