Title: Process for the Polymerisation and Copolymerisation of Vinyl Chloride in Aqueous Emulsion
IPC: C08F2/22
Filed: 1967-07-04
Abstract: 1,168,920. Vinyl chloride emulsion polymerization. WACKER-CHEMIE G.m.b.H. 4 July, 1967 [8 July, 1966], No. 30771/67. Heading C3P. Vinyl chloride is polymerized or copolymerized in aqueous emulsion in the presence of a polymer nucleating latex and 0À1-1% of an emulsifier based on the total weight of seed polymer and monomers which emulsifier is a water-soluble salt of an α-branched aliphatic or araliphatic saturated carboxylic acid. The stated amount of emulsifier must be present at the beginning of the polymerization and is preferably at least 10 times the amount needed to cover the surfaces of the polymer nucleating particles; it may be formed in situ or may be present in the polymer latex added. The acid may have the formula R<SP>1</SP>R<SP>2</SP>R<SP>3</SP>CCOOH where the R's are alkyl, aryl or aralkyl and R<SP>3</SP> may additionally be hydrogen and may be neutralized with alkali metal hydroxide, ammonium hydroxide or triethanolamine. Suitable comonomers are vinyl acetate, vinylidene chloride, vinyl esters, acrylic esters and unsaturated bicarboxylic acids and their esters. Reaction is effected at- 20 to 100 C. The catalyst is preferably a water-soluble peroxidic compound, e.g. potassium persulphate.

Title: Improvements in flying controls for aircraft
IPC: B64C13/00
Filed: 1946-10-16
Abstract: 619,988. Aircraft control systems. SAUNDERS-ROE, Ltd., KNOWLER, H., and SWAIN, A. E. Oct. 16, 1946, No. 30808. [Class 4] [Also in Group XXXII] In order to simulate " feel " in the poweroperated control system of an aircraft, a force which increases with movement of the pilot's control member 10 and also with airspeed is applied to the control member by connecting it to a piston 15 movable in a cylinder 16, both ends of which receive liquid from a pump 12, the liquid exhausting through two valves 23 whose extent of closure is governed by the two factors mentioned above. The control member 10 is connected to the piston 15 by a rack and pinion 13, 12 and the pressure on each side of the piston 15 is governed by the valves 23 between the delivery of the pump 18 and a reservoir 19. Normally, the valves 23 are open to the same extent so that there is no force on the piston 15, but as the control member 10 is moved from its neutral position, a rack and pinion connection 30, 31 to rod 29 causes this rod to move a lever 27 engaging a slot in rod 29 about its pivot 28, so moving a member slotted to receive the lever 27 and on which both valves 23 are mounted, to close one of the valves 23 and to open the other. A force is thus set up on piston 15 which corresponds to the movement of the control member 10 and tends to return this member to its neutral position. The rate at which this force increases with increase of movement of the member 10 is caused to increase with airspeed by mounting the pivot 28 on a strap 32 depending from a pressure-sensitive capsule 33 connected at 34 to a pitot tube measuring the dynamic head of air. In two further constructions, the valves 23 are operated by a follower bearing on a three-dimensional cam: in one, the cam is moved axially by the piston 15 and rotated by a rack and pinion connection to the capsule 33, in the other the piston 15 is replaced by a vane rotatable to vary the volumes into which a cylinder is divided by a fixed axial partition and the cam rotates with the vane and is moved axially by the capsule 33. Specification 619,984 is referred to.

Abstract: 1461929 Cathode-ray tube displays BRITISH BROADCASTING CORP 23 June 1975 [11 July 1974] 30817/74 Heading H4T In a dot-matrix type data display system respective detectors 18, 19 (Fig. 3) select control codes in a 7-bit data input on line 11 and via a bi-stable store 21 and switch driver 23 set a switch 22 to select for display either the output of an alphanumeric character generator 16 or, in the graphic mode, to select the output of a second switch 24. The latter is controlled via driver 25 in accordance with the value of the sixth bit (in store 20) which, when it is a "1" sets switch 24 in the position shown to select the graphic character generator 17 but which, when this bit is "0" selects the alphanumeric character generator which now supplies data for the display of an upper case character. This operation is made possible by employing either the ASCII or the ISO-7 codes, each of seven bits and each having bit 6 equal to "0" for all upper case characters. The relationship between the dot-matrices for graphic and for alphanumeric characters is discussed with reference to Figs. 1 and 2 (neither shown).

Abstract: 1,201,016. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 18 June, 1969 [21 June, 1968], No. 30849/69. Heading H1D. The colour selection electrode 1, Fig 1, of a colour television tube is supported from the tube face-plate by at least three flat bimetal springs 2, 3 and 4, each formed of two strips 16, 17, Fig. 4, of dissimilar metals welded side-by-side along the seam 19, as disclosed in Specification 1,192,725, to move the electrode towards the face-plate with rise of temperature, simultaneous movement of the electrode in its plane being prevented by choosing, for each spring, a length and effective expansion coefficient such that the component of expansion parallel to the side of the electrode is equal to the expansion of that part of the electrode lying between the centre of that side and the point of attachment of the spring, e.g. parts 7 and 8 for springs 2 and 3 of Fig. 1, for at least one spring the matching of expansions being achieved by laterally displacing the point of support 13 of the spring by the face-plate from the seam 19 of the spring, as shown in Fig. 4. By employing a support point situated a sufficient distance from the seam in a strip 17 having a very small expansion coefficient, a substantially zero expansion may be obtained, as is required for the spring 3 of Fig. 1, or an effective negative expansion by further increasing the distance from the seam, e.g. by using a point of support at C on the edge of the lug 18.

Title: Timing system
IPC: G06K7/016
Filed: 1966-07-11
Abstract: 1,136,665. Record timing. RADIO CORPORATION OF AMERICA. 11 July, 1966 [22 July, 1965], No. 31052/66. Heading G4M. A generator 120, Fig. 4, such as a timing disc coupled to the record feeding mechanism, produces 16 pulses per card column which are applied to a counter 126 enabling read gates 86 at a preselected count (17), and the counter is synchronized with the card columns by resetting it to a predetermined count (13) via line 104 Fig. 3 and gate 158 upon detection of a hole by sensing photocells 80 and OR gate 102. Counter 126 is only reset to 13 if it already holds a count between 11 and 18 or 27 and 2 as determined by circuit 166 being in the set state when the hole is detected. A hole detected outside this range causes an error signal to be produced by gate 160. The leading edge of a hole normally arrives when counter 126 registers 11, and pulses are then fed to a further counter 154, which on a count of 4 enables gate 158 to reset counter 126 from 14 to 13 when the hole is nearly centred on the sensing photocell. If a column does not contain a hole, pulses are not fed to counter 154 and counter 126 continues to advance, producing the next read-out pulse at count 17 as usual. If the next column is also unperforated, the next read-out pulse occurs on a count of 1, but if a hole is present the counter 126 will be reset to 13 before the count of 1 is reached and the read-out pulse will be at count 17 again. Other outputs from counter 126 are used to reset register 90, signal data processor 92 that new data is available and advance a column counter 194. Counter 154 prevents pin-holes from resetting counter 126 should they be detected within the preset count ranges. When the "all dark (P)" signal indicates the passage of the card trailing edge past photocells 80, and counter 194 registers 80, gate 196 resets read flip-flop 138 and gate 200 resets the synchronizing circuit. Detection of the trailing edge by photocell 82 resets 124 to close gate 122 and reset counter 126 to zero. When the leading edge of the next card is detected jointly by photocells 82, 80, 124 is set and pulses are supplied to counter 126. At a count of 29, corresponding to one column distance before the first data column, read flip-flop 138 is set and counter 126 is reset to zero so that it should have attained the correct count range by the time the first data column is sensed.

A method of detecting the presence, in a gaseous sample of oxygen or of a hydrocarbon in a mixture containing oxygen comprises mixing the sample with a measured quantity of hydrogen, contacting the resultant mixture with a catalyst which is active at room temperature e. g. palladium, to cause a reaction producing water vapour, and then testing the gaseous products for the presence of water vapour. In the apparatus shown in Fig. 1 a gas sample to be tested is contained in a device 7 e. g. a cylinder and piston or bellows device of known volume from which it may be expelled. A bottle 1 contains hydrogen under pressure and this is supplied through a pressure reducing valve 2 to a further device 5 of known volume by way of a multi-way cock 3. With the cock arranged so that hydrogen passes to the device 5, the device 7 is connected to a conduit 8 to enable the gas sample to be collected. The cock 3 is then turned to allow the contents of the devices 5, 7 to pass to a mixing bay 13, and then to a combustion chamber containing the catalyst. The gases then pass to a detector tube for water and if desired in the case of hydrocarbon detection to a carbon dioxide detector tube. In this case the conduit 8 contains a carbon dioxide absorbent filter, and means may be provided for the oxidation of any carbon monoxide to dioxide before passage of the gases through the detector.

Title: Process for permanently deforming hair, and compositions for use therein
Inventor: KALOPISSIS GREGOIRE
IPC: A61K/
Filed: 1965-07-21
Abstract: Hair is permanently waved or straightened by subjecting the hair constrained in a deformed state to the action of a composition containing at least one thiol and at least one disulphide of a thiol, the molar ratio of disulphide to thiol being at least 1:1 allowing the composition to act on the hair for at most 30 minutes to impart a permanent deformation thereto and then removing the composition and the constraining means.  The composition may be allowed to act on the hair for up to 30 minutes before the hair is rinsed and the constraining means removed.  Alternatively the composition may first be removed from the hair by rinsing while it is still mechanically deformed, e.g. wound on curlers, and a period of 5-30 minutes allowed to elapse before the curlers are removed and the final rinsing effected. Specified thiols are thioglycolic acid, thioglycerol, glycol thioglycolate, glycol thiolactate, b -mercapto ethanol, N-carboxymethylmercapto acetamide, thiolactic acid, b mercaptopropionic acid and glycerol thioglycolate and suitable disulphides are those of these thiols.  The composition may contain 0.2-0.8 moles per litre of thiol and the molar ratio of disulphide to thiol is preferably from 1.5:1 to 5:1.  The composition may also contain swelling agents, e.g. urea, perfumes and conditioning agents and may be adjusted to a pH of 8:5-9.5 by the addition of ammonia. In the straightening of hair the composition may be in the form of a cream which may also contain monoethanol amine stearate and the hair combed during contact with the composition.  The hair may subsequently be treated with a composition comprising cationic surface active agents e.g. trimethyl ammonium cetyl bromide and natural or synthetic resins, e.g. polyvinylpyrrolidone and lactic acid.  A solution of the thiol-and a solution of the disulphide may be packaged separately and mixed together prior to use.

Abstract: 1,036,495. Driving spindles. J. J. KEYSER. Aug, 4, 1964 [July 30, 1963], No. 31203/64. Heading D1D. A spinning spindle comprises means whereby a bobbin tube may be freely rotatably mounted on the spindle shank and clutch means whereby drive may be transmitted from the wharl to the tube. As shown in Fig. 1, a stationary spindle shank 1 has a freely rotatable and pivoted member 5 at its upper end to carry a bobbin tube 4 the lower end of which is adjacent the upper face of an extension 14 of the wharl 15. A sleeve 12, having a conical upper portion is rotatably mounted by a bearing 13 on the wharl extension 14 and is axially movable relative thereto. Three equi-angularly spaced clutch members 19 lie in radial apertures in an upward extension of the inner part of bearing 13 and are normally pressed against the foot of the tube 4 by the conical portion of the sleeve 12 which is downwardly urged by a spring 16, so that drive is transmitted from the wharl to the tube. If sleeve 12 is lifted the clutch portions 19 move outwardly by centrifugal action and drive to the tube is interrupted. To accommodate varying lengths of bobbin tube the shank 1 is adjustable in a resilient locating member 3. In a further form, vertical arms are pivoted inside an upward extension of the wharl and in normal operation clutch feet on the upper end of the arms are pressed against the inside of tube 4 by centrifugal action to transmit rotation thereto. The lower ends of the arms are bevelled and engageable by a bevel ring which is upwardly or downwardly movable by rotation of a shaft lying within the shank 1. On upward movement of the ring the lower ends of the arms are forced outwardly and then the upper ends move inwardly to suspend the drive. In Fig. 4 shank 44 is constantly driven by wharl 48 via a taper joint 49. A tube 4 is rotatably mounted on the shank by a member 46 and a bearing 58. On the outer part of bearing 58 is a sleeve 57 having an enlarged lower extension 56 in which slides a further sleeve 55 carrying a ring magnet 53, the sleeve 55 having portions which pass through vertical slots in sleeve 56 so that the magnet 53 may be vertically adjusted by a ring 59 on the outside of the assembly. A further ring magnet 52 is arranged on a flange 51 attached to the driven shank 44 and by moving magnet 53 close to or away from magnet 52 drive to tube 4 may be transmitted or interrupted.
