Title: Preventing theft and unauthorised use of automobiles
IPC: B60R25/10
Filed: 1948-01-27
Abstract: 670,496. Preventing unauthorized use of vehicles. KAPPEL, B. Jan. 27, 1948. [Jan. 30, 1947 ; July 14, 1947] Nos. 2394/48 and 2395/48. Class 118 (i). [Also in Group XXVII] A device for safeguarding a vehicle against theft comprises a relay R2 connected to a point in the electrical system which becomes live upon use of the vehicle, such as the dead side of the ignition switch 3, the relay coil circuit including contacts C4 which are closed by the authorised driver to condition the device to become operative. On operation of the relay, contacts C2 provide a holding circuit for the relay, contacts C1. short-circuit the ignition system 5, 6 and contacts C3 sound an alarm. This latter may be the horn 8 or an auxiliary alarm 11. As shown in Fig. 2, contacts C4 are actuated by a double-wound latching relay LR1 operated automatically when the driver leaves the vehicle by a door switch T2. To release relay LR for normal use of the vehicle, a secreted switch T3 is closed. Contacts T1 are associated with the housing of relay R2 and operate to complete the circuit for the relay if an attempt is made to gain access to the relay. In a simplified embodiment, Fig. 1 (not shown), contact C4 is replaced by a secreted manually-operated switch. Fig. 3 (not shown) illustrates an embodiment in which the latching relay is replaced by a continuously rated relay which operates from a door switch and holds operated over a local circuit. A secreted normally closed switch is provided to release the holding circuit. A switch such as T6 in Fig. 2 is provided to permit the system to be rendered inoperative without disclosing the location of the secreted switch. Contact C1 may be a normally closed assembly connected in series with the ignition circuit. The Specification, as open to inspection under Sect. 91, comprises also an embodiment, Fig. 4 (Cancelled, (not shown), in which the relay R2 is operated by switches associated with the doors, windows, bonnet, petrol-filler cap, etc. With this sytem in order to permit the authorised driver to enter the vehicle, the door switches are so constructed that a door may be opened without operation of the switch, a distance, insufficient to permit entry, but sufficient to allow an arm to reach the secreted release switch. As an alternative a time delay switch may be utilised. To prevent the vehicle from being towed away, a switch associated with the axle, drive shaft or transmission system may, operate relay R2. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in electric signal transmission systems
IPC: H04B14/02
Filed: 1942-02-27
Abstract: 555,619. Simultaneous telephony and telegraphy. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and HOUGHTON, L. W. Feb. 27, 1942, No. 2644. [Class 40 (iv)] [Also in Group XL] A telegraph system employs short unidirectional pulses which are sent at one frequency for marks and at a different frequency for spaces, and a simultaneous communication (e.g. speech) is sent by time modulation of the pulses. A sine-wave generator 1 is connected to a pulse generator 2 so as to generate pulses at the crests of the sine-wave. A second pulse generator 3 generates pulses at the troughs of the wave. Thus when the key 13 is closed pulses of double the sine-wave frequency are present in the mixer 4, whilst when the key 13 is open the pulse frequency is the same as the sine-wave frequency. The pulses may be applied to a radio transmitter 11, 15. Reception is obtained by passing the pulses through a filter which transmits one frequency and attenuates the other. A simultaneous telephony or other channel is afforded by time-modulating at 14 the pulses generated at 2. In an alternative telegraph system, the key is arranged to change the frequency of the sine-wave generator which in this case is connected to a single pulsegenerator, Fig. 5 (not shown).

Patent GB-1124975-A (GB)
Title: Improvements relating to the preparation of sulphur
IPC: C01B17/04
Filed: 1966-01-24
Abstract: Sulphur is made by reacting in a first stage a liquid heavy hydrocarbon fuel with O2- and SO2-containing gases at a high temperature so as to partially oxidize the hydrocarbons while partially reducing the SO2, subjecting the gases from the first stage to a catalytic treatment for further reduction of SO2 and to reduce any COS present, then subjecting the gases from this second stage to further catalytic treatment in a third stage to oxidize any H2S present and separate sulphur.  The gases are cooled between successive stages.  The heat extracted from the gases between successive stages can be used to preheat the gases before the first stage. The first stage temp. may be 1000-1200 DEG  C., the second stage may be 400-450 and the third stage temp. may be 250-280 DEG  C. The temp. of the first stage can be regulated by regulating the preheating of the SO2-containing gas and/or the quantity of free O2 which that gas contains. The amount of free and combined O2 contained in the gas may correspond to the amount required for complete oxidation of the hydrocarbon fuel.

Title: Manufacture of vat-dyestuffs and intermediate products therefor
IPC: C09B3/40
Filed: 1936-02-04
Abstract: Unsymmetrical vat-dyestuffs are made by reacting a ketone having the grouping <FORM:0459333/IV/1> and made by condensation of 1 mol. of pyrene with 1 mol. of a carboxylic acid characterized by the grouping <FORM:0459333/IV/2> or a halide or anhydride of such an acid, with a further molecular proportion of an acid as above defined but differing from that used in making the parent ketone, or a halide or anhydride of such an acid, in the presence of a condensing agent such as aluminium chloride or ferric chloride, at a raised temperature. Ketones specified are mono-benzoyl-pyrene, p-bromobenzoylpyrene, b -naphthoylpyrene, p-toluylpyrene, monocinnamoylpyrene, pyrenemonophthaloylic acid and halogenation products of such compounds; acids specified are benzoic acid, a toluic acid, a - or b -naphthoic acid, a phthalic acid, cinnamic acid.  The condensation may be effected directly with formation of a dyestuff by fusing in presence of a neutral alkali salt, or in presence of an organic diluent, whereby a di- or poly-ketone is formed which gives a dyestuff by further treatment in presence of a neutral alkali salt. The fastness of the dyestuffs may be improved by halogenation.  In examples, mono-benzoylpyrene or its bromination product is fused in presence of aluminium and sodium chlorides with (1) p-toluic acid-chloride (orange); (2) a -naphthoyl chloride; (3) m- or p-bromobenzoyl chloride; (4) cinnamic acid chloride (orange); (5) phthalic acid anhydride (brown-orange, more reddish on bromination; also, (6) mono-cinnamoyl-pyrene and (7) pyrene-mono-phthaloylic acid are condensed with benzoyl chloride; again, (8) mono-benzoyl-pyrene is condensed in acetylene tetrachloride with toluic acid chloride and the diketone so obtained condensed as above; finally, (9) benzoylene-phenylbenzpyrenone (obtained from mono-benzoyl pyrene and cinnamic acid chloride) is brominated.  The colours refer to the dyeings on cotton.

Filed: 1949-02-09
Abstract: <PICT:0667285/III/1> <PICT:0667285/III/2> In a molecular distillation apparatus, distilland 20 in the base of a highly evacuated chamber 10 is picked up as a film on a number of rotating discs 19 dipping into the distilland and carried close to condensing surfaces 21 cooled by circulating brine refrigerant and disposed adjacent the upper parts of the discs.  Condensate is collected in gutters 24 connected to a manifold 25 leading through a cooler 27 to a separator 26.  Two receivers 33, 34 are connected to the separator, either being lowered to receive the distillate as required.  The distilland is heated by an external heater 28 and the distillation controlled by means of vacuum gauge 32 and thermometer 29.  Distilland is fed to the chamber 10 at 13 and the chamber may be emptied at 30. Successive fractions from a single batch of distilland may be collected.  In a modification, Fig. 3 (not shown), heating is effected by passing fluid heated in an external chamber through a hollow shaft 39, Fig. 4, inside the shaft 15 carrying the discs 19.  The fluid emerges into the shaft 15 at one end and passes successively through the discs 19 which are hollow and have internal baffles 41.  Scoops 57 may be provided on the discs.  The temperature drops successively from disc to disc as the heating fluid cools and separate fractions are collected simultaneously from the condensing surfaces.  The distilland is passed continuously through the chamber 10 from an evacuated reservoir to an evacuated sump.  Alternatively the discs may be heated uniformly, the apparatus then effecting a simple distillation. The discs 19 may be heated electrically instead of by circulating fluid.
