Title: Improvements relating to variable speed power transmission arrangements
IPC: F16D67/00
Filed: 1957-10-09
Abstract: 829,842. Variable-speed gearing. DAIMLERBENZ A.G. Oct. 9, 1957 [Oct. 13, 1956], No. 31556/57. Class 80 (2). In a variable-speed transmission, particularly for motor vehicles, in which a hydro-dynamic clutch 6 is arranged in series with two planetary trains 11, 20, the driven portion 9 of the hydrodynamic clutch being fast with the sun-wheel 18 of the first train 11, and the planet-wheel carrier 19 of the first train serving to drive the second planetary train in all forward speeds, a releasable mechanical clutch 14 is provided between the driving portion 7 of the hydrodynamic clutch 6 and planet carrier 19 of the first train or, alternatively, the sun-gear 18. This clutch is arranged outside the casing 4 of the hydro-dynamic clutch 6 and adjacent the first planetary train 11. For starting and the lower gears the clutch 14 is released so that the drive is from the turbine wheel 9 of the hydrodynamic clutch to the sun-gear 18 of the first train, the annulus 21 of which is braked at 24. Two speeds of the carrier shaft 28 of the second train are obtained by either applying brake 25 or solid drive clutch 26. Two higher speeds are obtained by engaging the clutch 14 of the first train which by-passes the hydro-dynamic clutch 6 and drives the carrier 19 direct. For reverse the brake 15 is applied to hold the carrier 19 of the first train, the clutch 14 being of course released. In the alternative arrangement of the clutch 14 between the impeller 7 of the hydro-dynamic clutch 6 and the sun-gear 18 engagement of this clutch merely cuts out the hydraulic clutch 6 and drives the sun 18 direct from the impeller 7, the annulus 21 being held to still provide a reduction through the first train. Primary and secondary oil pumps 12 and 29 are provided for actuation of the brakes and clutches.

Patent GB-658428-A (GB)
Title: Improvements in or relating to an akylation process
IPC: C07C2/70
Filed: 1948-12-09
Abstract: An olefinic hydrocarbon fraction containing a mono-olefin of at least 7 carbon atoms, and preferentially oil-soluble, neutral, oxygen-containing organic compounds, including those having a carbonyl group, is contacted with an alkylatable compound, and a catalyst comprising liquid hydrogen fluoride, under alkylating conditions, alkylation products, and a liquid catalyst phase comprising said oxygen-containing compounds being separated from the reaction mixture.  C10-C15 fractions synthesized from carbon monoxide and hydrogen may be used to alkylate monocyclic aromatic hydrocarbons such as benzene and toluene and the alkylates sulphonated to produce detergents.  The catalyst phase may be treated to recover the oxygenated compounds and the catalyst recycled.  The alkylation temperature may be from about 50-250 DEG  F.  The amount of hydrogen fluoride may be 3-100 per cent or more by volume of the total reactants and should be sufficient to give two liquid phases. Alkylatable compounds which may be used include monocyclic aromatic hydrocarbons and substitution derivatives, e.g. benzene, toluene, xylene, ethylbenzene, n- and iso-propyl benzenes, ethyl toluenes, pseudocumene, butylbenzenes, chlorobenzene, phenol, cresols, anisol, phenetol, and benzoic acid, polycyclic compounds, e.g. naphthalene, anthracene, diphenyl, and naphthols, paraffins such as isobutane, isopentane, methylcyclopentane, and methylcyclohexane, and mixtures such as are produced by hydroforming of naphthas or solvent extraction of cracked gas oils.  The catalyst may contain minor amounts, such as 0.5-10 per cent by weight, of BF3, H2SO4, H3PO4, H3BO2F2, FSO3H, fluorophosphoric acids, SO2Cl2, ethane or toluene sulphonic acid, trifluoracetic acid or the like.  A C12 "Synthol" fraction may be introduced into a mixture of toluene and HF, the reactants being pre-dried, and the products passed to a stratifier. The lower catalyst layer may be passed to a recovery tower stripping gas being introduced if desired to separate HF and recover oxygenated compounds, viz. aldehydes and ketones.  The upper layer may be stripped of HF and fractionated to separate toluene from alkylate and unreacted olefins and paraffins.  The paraffins may be separated and worked up for use as detergents by conversion to alkyl halides and alkylation of aromatics followed by sulphonation or by conversion to alkanesulphonyl halides and thence to sulphonates.  Polyalkylates may be separated and recycled.  Comparative experiments in alkylation with HF, AlCl3, H2SO4 and solid phosphoric acid catalyst are given.

Abstract: 1,240,644. Ignition device. RONSON CORP., and LA NATIONALE S.A. 11 July, 1968 [11 July, 1967], No. 31922/67. Heading F4F. A cartridge 1 adapted to be mounted in a combustion device and containing a spontaneously combustible substance which is ejected through an outlet 2 when a boss 3 is struck has either means to prevent ejection of the substance or means to protect the user against accidental ejection when the cartridge is not mounted in a combustion device. In the embodiment shown, the cartridge has, on its opposite sides, arms 4 and 5 on which are pivotally mounted two shutters 6 and 7 which are biased by spring means (not shown) to the position shown in Fig. 1, thus masking the outlet. When the cartridge is mounted in a combustion device 11, a flange 9 on a sleeve 8 which surrounds the cartridge engages the device 11 to cause the cartridge 1 to move relatively to the sleeve 8 so that a flange 10 on the sleeve 8 engages extensions 12 and 13 on the shutters 6 and 7 to pivot them out of the masking position. In a second embodiment (Figs. 3 and 4, not shown), the outlet is masked by two shutters (16 and 17) rigidly mounted on the ends of a U-shaped leaf spring (15) in which the cartridge is cradled. Two projections (18 and 19) on the shutters (16 and 17) respectively engage in diverging slots (20 and 21, respectively) in a combustion device. In a third embodiment (Figs. 5 and 6, not shown), the cartridge is surrounded by a sleeve (25) which is closed at one end to mask the outlet. On mounting the cartridge the sleeve is moved against the action of a spring (26) so that the outlet is in line with an opening (30) in the side of the sleeve. In a fourth embodiment (Fig. 7, not shown), the cartridge is enclosed in a housing (35) having a flexible shutter 37 which runs in grooves in the housing. A projection (38) on the housing engages the device to move the shutter against the action of a spring to unmask the outlet. In the embodiment of Figs. 8 and 9 (not shown), a cap (45) masks the outlet and is rotated against the action of a spring (48) to bring an opening (47) in the cap into alignment with the outlet. In another embodiment (Figs. 10-14, not shown), the cartridge is surrounded by a sleeve (55) which is slidable on the cartridge and has a slot (56) on one side and in the end masking the outlet. An L-shaped member (57), fixed to the cartridge, is locked in position in the slot by a spring (58) which is disengaged to allow relative movement of the sleeve (55) and the cartridge when the latter is mounted on the combustion device. In a final embodiment (Figs. 15 and 16, not shown), the boss (3) has a circumferential groove (60) which is engaged by a latch (61) to prevent movement of the boss. On mounting the cartridge in a combustion device the latch disengages from the slot.

Filed: 1945-11-30
Abstract: 615,906. Automatic control systems for electric supply circuits. STANDARD TELEPHONES & CABLES, Ltd., and KELLY, R. Nov. 30, 1945, No. 32394. [Class 38 (iv)] An electric supply system comprises a plurality of automatically regulated sources which are further automatically added in parallel, or subtracted, as required to maintain the supply voltage constant. The supply voltage is applied to a relay JV which operates relays LV or HV according as the supply voltage is too low or too high. Relays LV, HV close contacts lv2, hv2, respectively to operate relays MR, ML to close contacts mr1, ml1 respectively to actuate the regulator MD of transformer T. At the lower and upper limits of regulation, the regulator closes switches LLS, HLS, respectively, to open switches MS and cut out the supply or close switches MS of a further supply transformer. The current from each source operates a relay JC so that when the current is below the predetermined limit, relay LC is prepared for operation by relay LV; but when the current is above the predetermined limit relay HC operates as before to reduce the supply. Manual operation is afforded by key K closing contacts kl or changing contacts k2. In a modification, the switches MS of one assembly are operated by a relay in series with relay JC in another assembly, Figs. 3, 4 (not shown). In a further modification, the supply sources are switched in and out in pairs and a marginal differential current relay additionally and differentially operates the regulators to balance the load between the sources of each pair, Figs. 5 and 6 (not shown).
