Title: Process for the manufacture of halogenophenolsulphonates

Filed: 1973-11-22
Abstract: 1410848 Halophenol sulphonic acids: halophenols RHONE-PROGIL 22 Nov 1973 [29 Dec 1972] 54271/73 Heading C2C Optionally alkylated halophenol sulphonic acids or salts or ethers thereof in which the phenolic OH or ether group is in the orthoposition to the sulphonate group are obtained by reacting a metal salt of an optionally alkylated polyhalobenzene-monosulphonic acid, at least one of the halogen atoms being in an orthoposition to the sulphonate group with a saponification agent, in the presence of at least one organic solvent having a dielectric constant less than or equal to 25 at 20 to 25 C., said solvent being capable of dissolving over 50% of the reagents at the reaction temperature. Specified saponification agents are alkali metal hydroxides and alcoholates. Specified organic solvents are aliphatic, cycloaliphatic and benzyl alcohols, amines, liquid polyethers and mixtures of solvents containing co-solvents which have less power to dissolve the reagents by themselves, e.g. oxygen-containing heterocyclic compounds. The reaction temperature is advantageously between 100 and 250 C. Examples are given which illustrate the process. Also, halophenols may be obtained by desulphonating and optionally hydrolysing the optionally alkylated halophenol sulphonic acids obtained above either by direct reaction of the reaction mixtures obtained in the above reaction or by reaction of the isolated products. Examples are given which illustrate this step of the process.

Title: Gas generators

Abstract: 1368504 Propellants; cooling gases by contact with liquids SOC NATIONALE DES POUDRES ET EXPLOSIFS 2 Dec 1971 [11 Dec 1970 (2)] 56055/71 Headings F3A and F4K [Also in Division F1] A gas generator supplying cooled combustion gases, e.g. to an inflatable safety bag in a vehicle, comprises in one arrangement, Fig. 2, an outer casing 1 the interior of which is divided by a partition wall 2 into a combustion chamber containing a solid propellant 10<SP>1</SP> and a reservoir 6 containing a vaporizable liquid. When propellant 10<SP>1</SP> is fired by igniter 13 combustion gases act on slidable piston 15 to force liquid from reservoir 6 through ports 8<SP>1</SP> into cooling chamber 7 to mix with combustion gases expanding through ports 9. The cooled gases exhaust through diffuser 20 to the point of use. A starshaped anti-splash plate 18 may be provided adjacent ports 8<SP>1</SP>. To assist filling of reservoir 6 the liquid may be enclosed in a flexible plastics capsule 16, e.g. of polyethylene, which punctures at weakened zones or by contact with sharp points 17 when piston 15 moves to compress the capsule. In a modification (Fig. 5, not shown) partition 2 and piston 15 are not provided and the liquid is contained in a flexible enclosure (39), e.g. of aluminium. In a further arrangement, Fig. 3, combustion gases exhaust from the cooling chamber 36 through parallel, convergent or divergent diffusion slots 23 in wall 22. Ignition pellets 33, e.g. of zirconium, interrupt communication between propellant 32 and slidable piston 26 closing liquid reservoir 25 until the pellets are fired. In another embodiment, Fig. 6, the gas generator comprises two half shells 42a, 42b welded together and gripping therebetween a flexible diaphragm 43, e.g. of aluminium or copper, to define a combustion chamber 45 containing propellant 46 and a liquid reservoir 44. Upon ignition combustion gases and liquid flow through ports 48, 49 respectively into annular cooling chamber 47 and thence through ports 50 into annular diffuser 51 before exhausting through ports 52. The vaporizable liquid may be water, mixtures of water and a lower alkanol or diol, e.g. methanol or glycol, or solutions of calcium chloride. The solid propellant has a short combustion time and may be a double base powder in the form of hollow strands, or a corrugated cardboard or lamellar type powder. The propellant composition by weight may be nitroglycerine 37 parts, nigrocellulose 56 parts, stabilizer 2 parts ballistic catalyst 1 part and pigments 4 parts.

Title: Electronic motor control
IPC: H02P23/00
Filed: 1974-12-04
Abstract: 1470782 Automatic control of speed FERRANTI Ltd 4 Dec 1974 [4 Dec 1973]  56111/73 Heading G3R In a digital motor control system, a reversible counter, which controls drive current to the motor, counts clockpulses in a direction dependent upon whether the measured motor speed is above or below a desired value, and the clockpulse rate is altered in response to the desired motor speed. As shown, counter 14 counts clockpulses during each cycle of pulse train from tachometer 12, whose output is shaped at 16 and has a frequency dependent upon the speed of motor 10. At least the most significant stages of counter 14 are compared with a desired motor speed signal as set in register, 18. A bi-stable circuit 20 is set if the count is greater than the desired value and reset by each pulse from shaper 16. A reversible counter 24 counts up or down according to the state of bi-stable circuit 20, and the contents of the counter are used to control the motor drive current e.g. by varying the firing angle of a thyristor or triac, provided the contents of counter 24 exceeds that of counter 26, which is reset for each half-cycle of the motor A.C. supply. To maintain stability, the maximum rate of change of the firing angle is limited by the frequency of clock 31 or by a submultiple of this frequency. The pulse rate of the clock 31 is lowered using the output of counter 14 and bi-stable circuit 39 if the motor speed is within a given range i.e. for small motor speed errors. Motor 10 may be a multi or single phase A.C. motor, a D.C. motor, a linear or stepping motor. The system can be used in a washing machine or an aerial attitude control.

Title: Machine for shaping gears
IPC: B23F5/14
Filed: 1970-12-04
Abstract: 1275010 Gear-shaping machine GLEASON WORKS 4 Dec 1970 [13 March 1970] 57771/70 Heading B3L A gear-shaping machine 20, Fig. 2, comprises a base 22, a housing 24 slidable on the base along a keyway 42, a work holder 30 rotatable about an axis 44, a tool holder 26 on which is mounted a rack-shaped tool 28 reciprocable in the vertical plane, and a generating train, Fig. 3, engaging both the work holder and tool holder for producing a relative generating motion therebetween. The workpieces 32 are fed to and from the machine by conveyers 36, 38, Fig. 1, and moved into and out of the work holder 30 by a turret 34. The work spindle has a ring gear 50, Fig. 3, thereon, which is rotated along with work holder 30 by a gear drive 46, which drive also rotates the lead screw 72 for feeding housing 24 along keyway 42. Gear drive 46 is driven by an hydraulic motor 76 which is supplied by a pump 80 connected to an electric motor 84 by a belt drive 82. The operation of the pump is controlled by a servo-mechanism 86. The effect of rotation of lead screw 72 on the movement of housing 24 along keyway 42 can be varied at preselected times by moving nut 74, Fig. 3, axially. This movement is produced by a cam 130, which when a clutch 128 is engaged moves a wedge assembly 132. Tool holder 26 is moved along axis 40, Figs. 1, 2, so as to feed or withdraw tool 28 by a cam 101, Figs. 3, 6, which pivots a lever 168 about a pivot point 170, the lever being connected to a yoke 162 on the tool holder. Tool holder 26 can also be moved bodily axially during generation of an oversize tooth on the workpiece, by a cam 190, Figs. 5 and 6, which moves a bracket 196 back and forth so that an adjustable actuator 198 on the bracket operates a bell-crank structure 202 connected to the yoke 162 on tool holder 26. Tool slide 222, Figs. 3, 7, 8, is reciprocated in the vertical direction by a motor 224, Fig. 3, connected to a drive shaft 228 by a belt drive 226, the drive shaft being adapted to be adjustably connected to slide 222 by a rod 230, Figs. 7, 8. The stroke of the slide 222 is varied by moving a serrated member 236 relative to a serrated cam 238. Cutting action only takes place on the downward stroke of slide 222. Slide 222 is pivoted at 229, and tool 28 along with the slide is therefore pivoted into and away from engagement with the workpiece by a cam 246, Figs. 7, 8, which cam engages rollers 254, 256, carried by the tool housing 223, cam 246 being moved vertically by cam 238. To enable tool 28 to be operated at high speeds, slide 222 has counterbalancing weights (266), (268), Fig. 10 (not shown). Workholder 30 is tilted into the machining position by a piston and cylinder arrangement 288, 290, Fig. 1. Tool 28 is reciprocated vertically relative to holder 26 by crank 230, it is moved with the holder along axis 40 by cam 101, it is moved with housing 24 along keyway 42 by lead screw 72, this movement being varied if required by the use of wedge assembly 132, it can be moved bodily during generation by cam 190, and is pivoted by cam 146.
