Title: Improvements in or relating to course indicators or the like for ships, motor vehicles or other steerable bodies
IPC: G01C21/20
Filed: 1922-01-28
Abstract: 196,983. Buckle, G. F., and Parfett, F. Jan. 28, 1922. Course-recording apparatus.-In apparatus of the kind in which two members are moved in directions at right-angles to each other in parallel planes to indicate on a map &c. the position at the moment of a ship, motor-car &c., the relative speeds of the two members are automatically controlled by the steering of the body. This may be effected for instance by the difference in speed of the wheels of a vehicle arising when it turns corners. As shown, the indicator described in Specification 158,672, in which the relative speeds of a constantly driven map and pointer are controlled by a manually operated setting member, is modified so that the setting member is continuously under the control of the vehicle and is moved whenever the near and off wheels of the vehicle have different speeds. Two flexible shafts 200, 201, Fig. 1, are connected respectively to the near and off side road wheels. The shaft 200 drives a sun wheel 203 of a differential gear, Fig. 3, and also through gearing 204, 205, 207, 208 drives a shaft 209 which forms the main drive for the map and pointer. The flexible shaft 201 drives through gearing the other sun wheel 214. The planet wheels 215, 216 are carried in a cage 217 provided with a bevel wheel 218 which is geared to worm wheel 222 on a sleeve 223 surrounding a shaft 224 carrying a disc 113 which controls the relative speeds of the map and pointer as in the prior Specification. The shaft 224 also carries a friction member 228 co-operating with a conical surface on the worm wheel 222. When a finger nut 221 on the shaft 224 is screwed up, the member 228 is clutched to the wheel 222 and the disc 113 rotates with the latter, when differences of speed of the road wheels cause movement of the cage 217, but when the nut is slackened the disc is disengaged. This clutching arrangement is provided to allow of a manual control of the relative speeds of map and pointer through the setting member 110. In the present invention the automatic means for correcting the increase of speed of the map due to the increase in the operative diameter of the roller as the map is wound up is omitted. Preferably the driving and controlling mechanism is separate from the map and pointer and is connected thereto by flexible shafts. The same controlling mechanism may actuate several maps and pointers. Reference has been directed by the Comptroller to Specifications 10074/10, 141,453 and 172,147.

Title: Improvements in the manufacture and production of esters
IPC: C07C69/16
Filed: 1927-01-31
Abstract: 265,233. I. G. Farbenindustrie Akt.- Ges. Jan. 29, 1926, [Convention date]. Mono-esters of glycol or its homologues are prepared by heating alkylene oxides with organic carboxylic acids in the presence of alkali metal salts of the organic acid employed. An example is given of the preparation of glycol monoacetate by interaction of ethylene oxide with acetic acid containing sodium acetate. The Specification as open to inspection under Sect. 91 (3) (a) states that glycol esters and their derivatives are prepared by heating alkylene oxides, or their substitution products free from halogen, with organic acids or their anhydrides or substitution products, in the presence of catalysts. Mixed esters may be obtained by using a mixture of carboxylic acids; the reaction may be effected under pressure. Catalysts which form reactive complex compounds with the organic acid, which compounds are more strongly acidic than the free acid, are especially suitable, e.g. mineral acids, acid salts thereof such as sodium bisulpbate, and salts of organic acids with strong bases; neutral salts, such as alkali metal salts of the carboxylic acids, may also be employed. Examples are given according to which glycol monoacetate is obtained by passing ethylene oxide into hot acetic acid containing sulphuric acid, and glycol diacetate by introducing ethylene oxide into a boiling solution of sulphuric acid in acetic anhydride. This subjectmatter does not appear in the Specification as accepted.

Abstract: 354,155. Control of motors ; controllers. LAABS, E. H., 12th Street, Milwaukee, Wisconsin, U.S.A. Jan. 28, 1931, No. 2781. Convention date, Feb. 8. [Class 38 (iii).] With auxiliary starting motor.- A printing press is " inched " by a small induction motor M1 and is run at high speec by a large motor M2, the speed of which is controlled by a motor - operatec crosshead controller 3 used to cut out rotor resistances R1, R2, R3. The two lowest speeds of the motor M2 are maintained constant by a fluid pressure device, Fig. 3, driven by this motor and controlling a contactor 4 which includes and excludes resistances R4, R5 intermittently in the rotor circuit. At higher speeds, the contactor 4 remains closed. The control circuits are disclosed in Fig. 1 (not shown), and include a " safe " button and relay, a " reset " button and relay which must be closed momentarily to cause closure of a " stop " relay, closure of which is necessary before an " inch " button and relay are effective to cause the motor M1 to start. A " safe-after-inch " relay causes opening of the " stop " relay after each inching operation. " On " and " off " buttons cause step-by-step operation of the pilot motor driving the controller 3, which during its " on " movement first starts the motor M1, then the motor M2, thereafter shutting down the motor M1 and speeding up the motor M2.

Title: Improvements in the production of sponge iron
IPC: C21B13/00
Filed: 1950-02-06
Abstract: 678,458. Reduction or iron ore. KOPPERS CO., Inc. Feb. 6, 1950 [Feb. 5, 1949], No. 3025/50. Class 72 [Also in Group XII] In a method of producing spongy iron by reducing iron ore by carbon monoxide and hydrogen, a gas having a carbon monoxide plus hydrogen content of more than 70 per cent and preferably more than 85 per cent is produced by gasifying a solid fuel with oxygen and endothermic gaseous media at a temperature high enough to reduce the ore but not higher than 1000‹C and brought into contact with the iron ore without substantial change in temperature or composition. As shown, pulverized solid fuel and oxygen are introduced from a nozzle 8 into a combustion chamber 1 in such a ratio that carbon monoxide at high temperature is formed. A cold endothermically reacting gas, e.g. steam or carbon monoxide, may be fed down the sides of the chamber to control the temperature of the gases and a further amount of cold gas rich in carbon monoxide may be added through inlets 16 to produce a reducing gas at a temperature of not more than 1000‹C. Any ash produced may be removed through an ash box 20. The reducing gas is fed into the bottom of a reducing shaft 22 containing iron ore which is fed downwardly. The reducing shaft may operate under increased pressure. The spent gas may be passed through a dust separator 28, a cooler 31, and a scrubber 36 leaving a gas containing carbon monoxide and hydrogen which may be re-used in the process. Lumpy solid fuel may be used in the producer which may be of the ash-melting type. Specifications 673,161 and 673,162, [both in Group XII], are referred to.

Abstract: 450,440. Knitting-machines. MILLER, M. C., Manville, Rhode Island, U.S.A. May 3, 1935, No. 3514/36. Convention date, May 18, 1934. Divided application. [Class 74 (ii)] In devices for forming welts on stockings in process of being knitted on a Cotton's machine, a welt wire is automatically laid in after the first few courses to take the strain off the welt hooks during continued knitting of the welt. The pattern-mechanism oscillates a rod 18 on the take-up release assembly and pulls control rods 12 so that levers 4 are tripped. A welt wire previously placed by hand on the top of these levers, then falls down inclined guideways 1 in two stages and comes to rest gently on the fabric. Since the take-up release acts only when the narrowing points are in motion and no narrowing is necessary, for welt formation, the points are racked out to their customary position beyond the needle bed and perform there a dummy narrowing motion during welt formation. Specifications 351,969 and 367,193 are referred to.

Abstract: 972,712. Dyeing and printing keratinous fibres; dyeing apparatus. INSTITUT TEXTILE DE FRANCE. Jan. 31,1961 [Feb. 3, 1960(2)], No. 3655/61. Headings D1B and D1L. The affinity of a liquid treating agent, such as a dye liquor, for keratinous fibres such as wool is increased by first subjecting the fibres to the action of a silent electric discharge in a rarefied atmosphere. Differential dyeing effects may be obtained by dyeing a mixture of fibres some of which have been subjected to the ionic bombardment, or by locally applying the bombardment to the material to be dyed. Local bombardment may be effected by the use of insulating masks or stencils, or by the use of perforated electrodes or electrodes with parts in relief. Differential dyeing effects are also accompanied by differential shrinkage effects. Large masses of keratinous fibres in a very open form are best treated between electrodes each of which is provided with a stabilization layer of insulating material, although with a thin material, such as a fabric, only one electrode may be provided with a stabilization layer. As shown, the keratinous fibrous material T is guided by rollers 11, 11<SP>1</SP> between the electrodes 12 of a set of plane condensers fed with a high voltage alternating current, all of which are housed in a chamber I in which a rarefied atmosphere is maintained by a vacuum pump 27. The fibrous material enters and leaves chamber I via air locks 10 and 13, and is then passed through a dyebath II, a fixing device 14, washing and rinsing devices 15 and 16, wringing rollers 17 and a dryer 18, being finally collected at R<SP>1</SP>.
