Title: A process for the production of improved petroleum resins
IPC: C08F36/04
Filed: 1962-09-12
Abstract: Petroleum resins are produced by mixing a fraction of b.p 140-280 DEG C. containing styrene and styrene derivatives with a fraction of b.p. 20-100 DEG  C. containing diolefines (both fractions having been recovered from a thermally cracked petroleum oil fraction) in such a ratio as to give a desired softening point and degree of unsaturation of the product, polymerizing the mixture in the presence of a Friedel-Crafts catalyst and subsequently treating the product to remove non- and lower-polymerized materials and catalyst.  The styrene fraction also contains methyl styrene and indene and its derivatives. The diolefine fraction also contains C5-6 mono- and di-olefines.  The catalyst may be aluminium halide, boron halide, e.g. triflouride, or its complexes, e.g. ethyl etherate or phenol, ferric chloride and stannic chloride. A catalyst decomposing agent, e.g. calcium hydroxide containing 0.1-15% water, may be added to the polymerization product and the solid matter filtered off.  The non- and lower. polymerized materials may be removed by steam-distillation.  The resins may be used for paper-sizing.

Patent GB-191037-A (GB)
Title: An improved process for the treatment of hydrocarbons particularly of crude petroleum
IPC: C10G29/06
Filed: 1922-12-22
Abstract: Crude petroleum or other hydrocarbon is heated with soaps of sodium, iron, alkaline earth, or other metals, whereby at 100-110 DEG  C. or over the hydrocarbon is desulphurized, and on distillation the fractions are clean and sharp.  A few drops of water, or a catalyst in the form of an alkali metal or an alkaline earth metal, e.g. 5.5 per cent. of sodium, are preferably added.  The desulphurization of hydrocarbon oils by (1) heating crude petroleum or other oil with small pieces of ferrous sulphide; (2) passing the vapours of petroleum distillates through a solution of metal soaps; or (3) acidifying a cold mixture of burning oil and metal soap dissolved in burning oil distillates so as to precipitate the metal of the soap, and afterwards neutralizing by alkali, is also described.

Title: Improvements relating to electrical supervisory systems such as fire and burglar systems and the like
IPC: G08B23/00
Filed: 1929-11-15
Abstract: 343,972. Charging storage batteries. KIDDE & CO., Inc., W. and GRANT, H. C., 140, Cedar Street, New York, U.S.A. Nov. 15, 1929, No. 35023. [Class 38 (iv).] Relates to systems for supervising electric circuits in which a supervisory current normally flows through a circuit so that in the event of derangement of the circuit due to a fault an alarm is operated. As shown in the Figure, a plurality of protective circuits c, c<1> containing thermostats or burglar contacts d bridged by resistances e is normally fed in parallel from battery a the current energizing relays f but being insufficient to operate relay g. In the event of derangement of a protective circuit the corresponding relay f is released to operate the individual alarm lamp f<7> and the common alarm bell f<8>. In order to render the common alarm bell f<8> available for use on other circuits after receiving an alarm, the switch f<10> corresponding to the affected circuit is operated to cause re-energization of relay f and thereby open the bell circuit, the individual alarm circuit however being maintained over the contacts of switch f<10>. In the event of operation of a protective contact d the corresponding resistance is shortcircuited and the line current is strengthened to cause operation of local indicator c<2> and energization of relay g which operates the main alarm g<4>. In a modification each switch f<10> is arranged in series with the contact f<2> and is arranged when operated to close the circuit of the lamp f<7> over a contact in parallel with f<1>. This arrangement avoids the temporary switching out of the lamp f<7> during operation of the switch f<10>. In a further modification the battery a is replaced by any suitable source of direct current and a battery is provided which may be switched into operation upon failure of the main supply. The battery is continuously under charge from the supply and is supervised by a relay similar to the relay f. In the event that the current ceases to flow in the battery circuit the relay is de-energized to operate two indicators one of which may be rendered inactive in the manner previously described.
Patent GB-811449-A (GB)
Title: Improvements in or relating to the preparation of lime water
IPC: C01F11/02
Filed: 1956-11-16
Abstract: <PICT:0811449/III/1> <PICT:0811449/III/2> Lime water is prepared, especially for use in the purification of water, by introducing water and milk of lime continuously as separate streams into a vessel, the size of the vessel and the rates of feed of water and milk of lime being such that a major proportion of the lime in the liquid continuously withdrawn from the outlet of the vessel is in the form of lime water.  Hot or cold water may be used for the water feed, or the water feed may be of variable temperature; the rates of feed of water and milk of lime may also be variable.  If raw water is used for the water feed, it may be necessary to evacuate at intervals the precipitates which have formed in the vessel.  In Fig. 1, milk of lime from vessel 1 is fed to vessel 3, while water is introduced into vessel 3 through pipe 4.  Lime water is drawn off through pipe 6 and fed to vessel 7.  Water to be purified is introduced into vessel 7 through pipe 13.  An alternative form of vessel 3 is shown in Fig. 2, wherein a water jet blower 8 receives water from pipe 9 and feeds an emulsion of air and water into vessel 3 through pipe 10.  The mixture of water and milk of lime passes up through central column 11, down through annular space 12 and up again through the outer space of the vessel, lime water leaving the vessel at 14.

Title: Improvements in or relating to Control Means for a Machine Tool
Inventor: VARGA JOHN MAXIMILLIAN JULES
IPC: G05B19/16
Filed: 1966-08-05
Abstract: 1,198,985. Automatic speed control; programmed electric control. CARDING SPECIALISTS (CANADA) Ltd. July 26, 1967 [Aug. 5, 1966], No.35155/66. Headings G3N and G3R. [Also in Division B3] A reciprocable member of a machine carries a length of magnetic tape 16 past a pick-up head 17, the tape having as many parallel tracks as movements of the member are required in a machining cycle, the head being aligned with each track in turn. The member, such as a turret slide of a lathe, is driven by a double-acting hydraulic cylinder fed with pressure oil through a reversible valve and an adjustable valve 23. Each track on the tape comprises a frequency modulated waveform, the output from head 17 being fed to a discriminating network including two resonant circuits tuned respectively above and below a reference frequency. The outputs from the resonant circuits are amplified and applied to opposed electromagnets 24, 25, co-operating with armature 26 carrying nozzles 28, 29. Oil is bled off from each nozzle and supplied to opposite ends of cylinder 30 having piston 31 for actuating the valve 23. The turret slide is decelerated or accelerated when the detected frequency is greater or less than the reference frequency so that the speed of the slide is determined by the pitch of the recorded waveform. Each track may have amplitude modulation at its end to effect reversal of the slide, or a continuous track of constant frequency, extending along the tape, may be associated with another head, the slide being reversed when the additional head gives no output. The speed and direction of the spindle may be controlled by additional tracks, as well as indexing of the turret. The cross slide carries its own tape. The tapes may be replaced by drums.

Title: Voucher-sorting apparatus
IPC: B07C3/06
Filed: 1959-10-16
Abstract: 885,929. Sorting records. SCHICKENDANZ, G. Oct. 16, 1959 [Oct. 16, 1958], No. 35170/59. Class 106 (1). In sorting apparatus for records such as cheques or vouchers, the records are presorted into groups separated by end-of-group slips and after each group has been sorted into the pockets 6 the detection of the end-ofgroup slip causes marker slips to be fed from magazine 2 one into each sorting pocket to indicate the end of the group in each pocket. The end-of-group slips separating the groups in magazine 1 may be coloured so that they may be seen easily and the sensing means may respond to the colour. As the records leave the magazine 1 they are sensed at 3 and a coil 5 operates deflector blades to conduct the records to the appropriate pocket. The data sensed also passes to a data store 4 consisting of a number of binary storage units (e.g. triggers or cores) one for each of the pockets 6. The arrangement is such that as each pocket is selected the corresponding storage unit is set so that a record is stored of the pockets to which cards have been fed. When the sensing device 3 detects the end-of-group slip it renders the feeding means for the magazine 1 inoperative and that for the marker slip magazine 2 to be started. The end-of-group slip follows the last record into the appropriate pocket. The deflector control coil is now energized from the data store 4, the storage units of which are read out in turn and the corresponding deflector operated wherever the unit is set, except in the case of the pocket containing the end-of-group slip. By this means the marker slips from magazine 2 (which are identical to the end-ofgroup slips) pass to those pockets which are selected by the store 4. When the store 4 is fully cleared the feeder of magazine 1 re-starts and the next group is sorted as before. A printing device 8 makes a mark on each record in turn, the mark changing at the end of each group. Sorting on two denominations may be effected by two sorting operations. A number of such sorting units may be used together, the printing devices 8 being controlled as regards the sequence of marks to be printed by a central control device.

Title: Location of faults in electric cables
IPC: G01R31/02
Filed: 1974-07-25
Abstract: 1468022 Locating faults in cables BICC Ltd 25 July 1974 [25 July 1973] 35446/73 Heading G1U Having established that a conductor 4, 5, Fig. 1 in a multi-core cable is broken, the location of the break is found by connecting one part 5 of the broken conductor to the other conductors and to earth as shown, by causing small localized flexing of the cable, for example by striking it with a tube 7, and by simultaneously detecting any resultant change in potential of the isolated part 4 of the broken cables. According to the Specification each blow by tube 7 causes a momentary change in the potential of the isolated part 4 of the conductor, the magnitude of the change when the blows are just before the break on part 4 being substantially larger than when the blows are just past the break on the earthed part 5. Thus, by applying a succession of blows along the faulty conductor the location of the break can be determined by noting the position at which the resulting potentials on the isolated part 4 change abruptly in magnitude.
