Title: Apparatus for storing and winding discontinuously and reversibly moving tape
Inventor: ENGEL JEAN-PIERRE
IPC: G03B21/43
Filed: 1969-09-05
Abstract: 1,244,896. Automatic control of tape drives. J. P. ENGEL and M. WICHOUD. Sept.5, 1969 [Sept. 6, 1968], No.44141/69. Heading G3R. In apparatus for reversibly driving tape past a reader between driven spools, the speeds of the spools are electronically controlled by voltages dependent on the lengths of loop between the tape drive and the spools to correct changes in these lengths, and by voltages dependent on the radii of the outermost turns of tape on the spools to compensate for changes in the radii. In Fig.1, a tape carrying information for the control of a knitting machine may pass in either direction between spools 2 and 3. The information is read by a head 17 through which it is driven intermittently by a stepping motor, synchronized with the knitting machine, engaging sprocket holes in the tape. A further stepping motor, also synchronized with the knitting machine, drives a drum 5 engaging sprocket holes in the tape on either side of head 17. A flexible coupling between drum 5 and its drive makes movement of the drum continuous despite the stepping of the motor. Between drum 5 and each of the spools, which are separately driven, loops of tape formed by multiple pulley systems are extended by spring urged levers 12 and 13 which also operate potentiometers 22 and 23 having equipotential end portions. Further levers 8 and 9, spring urged into engagement with the outermost layers of tape on the spools, operate potentiometers 19 and 20. The speed of each spool driving motor is automatically controlled, through a transistorized follow-up speed control system, in dependence on the speed of the knitting machine and the positions of potentiometers 19, 22 or 20, 23. The arrangement is such that, as the tape builds up on a spool, potentiometer 19 or 20 decreases the speed of the spool, and if the speed of the knitting machine or the spools changes, or the loop lengths vary on reversal due to inertia, potentiometers 22 and 23 vary the speeds of the spools in such sense as to tend to restore the loop lengths to normal.

Title: Improved composition for the cold permanent waving of hair
IPC: A61K8/42
Filed: 1959-12-31
Abstract: A composition for use in the cold permanent waving of hair comprises 10 parts by weight of a water-soluble keratin reducing mercapto compound, 1-10 parts by weight of an alpha-omega bifunctional compound of the general formula X-Z-Y in which X and Y are each either -CONH2 or -C­N and Z is -CH(CH3)CH2-, -CH2CH(CH3)CH2-, -CH(CH3)CH2CH2-or -(CH2)n-, n being an integer of 1-4 except when both X and Y are -C­N in which case n is 2, and an alkaline material which, when the composition is used in an aqueous medium, imparts to the medium a pH of 7-10, the concentration of mercapto compound used being sufficient to wave hair and being equivalent to at least 0.6% thioglycollic acid. The mercapto compound may be a low molecular weight water-soluble mercaptan containing another functional group, e.g. a carboxyl, hydroxyl or amide group, in addition to the mercapto group and is preferably a mercapto alkanoic acid containing 2-6 carbon atoms or a salt thereof.  The alkaline material may comprise a weak base having a dissociation constant of less than 10-3, e.g. ammonia, monoethanol amine, diethanolamine, tris (hydroxymethyl) amino methane, 2-amino-2-methyl-1,3-propane diol, triethanolamine and glycerylamine, to which soluble carbonates and bicarbonates may be added to stabilize the pH, or a mixture comprising a major proportion of a weak base and a minor proportion of a strong base, e.g. an alkali metal hydroxide.  The composition which may also contain a perfume and a wetting agent, e.g. t-octyl phenol condensed with 9-10 moles of ethylene oxide, may be packaged in dry form, used to impregnate a pliable sheet or mixed with water and a propellant gas in liquified or dissolved form so that it can be dispensed from a pressurized container.  After treatment with the composition the hair may be rinsed and treated with a solution containing sodium perborate and citric acid or subjected to aerial oxidation.  Specification 860,978 and U.S.A. Specifications 2,719,815 and 2,736,323 are referred to.

Abstract: 1,205,447. Aromatic hydroxy carboxylic acid salts. TENNECO CHEMICALS Inc. 3 Oct., 1967 [5 Oct., 1966], No. 44945/67. Heading C2C. An alkali metal salt of a hydroxy aromatic carboxylic acid is made by reacting carbon dioxide with alkali metal phenate particles having an average particle size of less than 70 microns at an elevated temperature and in the absence of water, the carbon dioxide being passed continuously through the reaction zone to which it is admitted undiluted and removing therefrom by-product phenol. The process is preferably carried out at 100-300‹ C.

Abstract: 1,209,985. Road vehicle detectors. SIEMENS A.G. 24 Sept., 1968 [25 Sept., 1967], No. 45258/68. Heading G4Q. An inductive-loop vehicle detector comprises a phase comparator 12, 13 to one input of which is applied a voltage signal that is produced across an impedance formed by a series combination of an untuned loop 5 a resistor 6 and a resonant circuit 7, 8, 9; and to the other input of which the voltage across the circuit 7, 8, 9 only is applied. The resistor 6 preferably has a resistance equal to the reactance of the loop, and the circuit 7, 8, 9 may be de-tuned to adjust the comparator output signal level.

Abstract: <PICT:1020567/C1/1> Glass-forming ingredients are separately heated to reaction temperature and are then fed in dispersed form into a chamber where vitrification occurs. Sand is stored in a chamber 2 heated by the flue gases and from which it is fed first on to plates whereon it is stirred by teeth 3, and then via conduits 6 and conveyers 19 into the upper end of a reaction chamber where it meets an upwardly flowing stream of gas heated by burners 7.  As it falls, it meets a cloud of alkali and alkaline-earth metal carbonates which have been melted by the flue gases in a tank 4 and fed by a heated pipe line 12 to nozzles 11. The lower part of the reaction chamber is of slightly conical shape so as to cause an increase in the velocity of the upwardly-flowing gas stream; a higher pressure is created along the walls of the chamber by a combustion grid 10 to confine the reaction zone to the centre of the chamber and prevent the formation of glass globules on the walls.  The sand enters the reaction chamber at a temperature over 900 DEG  C. but below that at which it frits or is converted into a less-reactive crystalline form, e.g. between 1450 DEG  C. and 1600 DEG  C.

In the neutral position shown fluid from a pressure source passes to inlet 62 of valve 26 and via bores 146, 140, 144 annular groove 122, notch 136 and bore 70 to an exhaust chamber 72. Clutch actuation line 66 also connects chamber 72 via groove 122 notch 136 and bore 70. Movement of bell crank 34 by a manually actuated lever (22) (Fig. 1 not shown) to a first position causes member 96 to move spool 48 via spring 102 to the left and annular groove 122 connects inlet 62 with the clutch line 66 to disengage the clutch. On further leftward movement of the spool brake line 60 is also connected to inlet 62 via groove 120. Fluid passes from line 60 via annular groove 210 and passages 212, 213 of valve 32 to the rear of piston 208 thus urging the piston to the right to actuate via lever 38 the brakes. To operate the brakes independently of the clutch a pedal operated crank 36 is provided which presses on a plunger 164 slidably housing a spool 188 and itself being slideably received in a member 168. On movement of plunger 164 to the right spool 188 abuts piston 208 to block passage 213. Radial bores 192 in the spool and plunger are brought into alignment and open into chamber 214.
