Title: Process of recovering aluminium chloride used in the conversion of high boiling point hydrocarbons into low boiling point hydrocarbons
IPC: C10G11/08
Filed: 1921-08-22
Abstract: In converting high-boiling hydrocarbons into lower-boiling oils by heating with aluminium chloride, the sludge, which forms in the reaction vessel, is withdrawn while liquid and before the catalyst in it is completely spent, and is sprayed into a heated chamber to cause vaporization of aluminium chloride.  The vapours may be washed with hydrocarbon oil to absorb the aluminium chloride, which is returned to the reaction chamber.  The process is carried out in the apparatus described in Specification 189,200, [Class 32, Distilling &c.].ALSO:In converting high-boiling hydrocarbons into lower-boiling oils by heating with aluminium chloride, the sludge, which forms in the reaction vessel, is withdrawn while liquid and before the catalyst in it is completely spent, and is sprayed into a heated chamber to cause vaporization of aluminium chloride.

Title: Electric signal translating circuits employing transistors
IPC: H03F3/183
Filed: 1952-09-05
Abstract: 714,812. Transistor amplifying circuits. WESTERN ELECTRIC CO., Inc. Sept. 5, 1952, [Sept 17, 1951], No. 22367/52. Class 40 (6) In a transistor amplifying circuit having an output transformer connected in the signal output circuit, the direct-current feed to the transistor is arranged via a second transistor while the output transformer is arranged to carry signal currents only. The output transformer consequently carries no direct-current component and a transformer of very small dimensions may be used. By virtue of the fact that the impedance of a transistor to small amplitude alternating currents may be made considerably greater than its D.C. resistance, the second transistor may be arranged to supply an adequate biasing current to the amplifying transistor while not unduly bye-passing the amplified signal sent to the output transformer. Fig. 1 shows a circuit employing two junction transistors of the N-P-N type. The input applied at 10 is amplified by transistor T1 and passed through condenser 20 to output transformer 21. Direct-current for energizing the transistor Tl is supplied from battery 15 via the collector and emitter of transistor T2. Fig. 2 (not shown) shows a circuit employing two point transistors. Fig. 5 (not shown) shows a circuit comprising an amplifying junction transistor fed through a point transistor while Fig. 6 (not shown), shows a circuit comprising an amplifying point transistor fed through a junction transistor. In the circuits of Figs. 5 and 6 the signal input is applied to the first transistor through a resistance-capacity coupling network. In the embodiment of Fig. 4 employing two junction transistors, the potential of the base electrode and consequently that of the emitter of transistor T2 are held constant as regards the direct-current component by the potential divider 31. However negative feed-back as regards signal currents is supplied by the resistor 19 1  and condenser 29 thus increasing the alternating-current impedance of the transistor.

Title: A new or improved combined cigarette or cigar case and lighter
IPC: F23Q2/32
Filed: 1932-08-10
Abstract: 405,682. Lighters combined with cigarette &c. cases. CLAYTON, G. A. J., 1, St. Leonards, Rydens Grove, Hersham, Walton-on-Thames. Aug. 10, 1932, No. 22386. [Class 75 (iii).] A common operating member is provided for partially ejecting a cigarette and for releasing a spring-actuated ignition means for the lighter. The operating member is a knob whose axle projects into the case and is there formed with lugs 33; and when the knob is turned in an anti-clockwise direction, one of the lugs engages projections 35 on slides 21, 22 and moves the latter to the left. A turned-up flange 16 on the slide 21 serves to eject partially the topmost cigarette through an aperture 18 in the case. Towards the end of the movement of the slide, an incline 55 thereon engages and pushes up a stud 50 on a spring catch 47 and releases the hood 42 of the lighter, the hood then moving to the right under the action of two springs 43 in tubular housings. A pivoted hook 51 on the hood pressed by a spring towards the flint wheel 38 of the lighter engages a pin on the wheel and rotates it to produce a spark. The movement of the hood may be stopped by a pin, not shown, on the hood engaging the bracket carrying the flint wheel. If the lighter fails to ignite, the hood is reclosed and the operating knob turned until the lugs 33 slide past the projections 35, the slides then being returned to their normal position by a spring 24. Reverse movement of the operating member causes a lug 33 to engage the opposite face of the projections 35 and, owing to the lost motion connection between the slides afforded by pin and slot connections 28, the slide 22 will be moved to the right until a cam surface 56 thereon engages the stud 50 and releases the hood again. The slides are guided by an upstanding projection 23. The case and lighter are formed integral from a single metal stamping or pressing. According to the Provisional Specification, the slide moves in an arcuate path and is governed by two stops on either side of it, a spring being wound about the slide and abutting against the stops at one end and the turned up end of the slide at the other ; the lugs 33 engage the turned up end of the slide ; the lighter may be ignited by the reaction of the slide after it has ejected a cigarette ; and a pawl attached to the hood acts on a cog wheel on the spindle of the flint wheel.

Title: Improvements appertaining to locks or locking mechanism of doors and the like
IPC: E05B65/00
Filed: 1929-07-23
Abstract: 326,432. Jones, T. P. July 23, 1929. Locks, controlling operation of; locks for safes. - Mechanism for locking and unlocking a safe or the like by operating on a key 3 fixed in the safe lock is contained in a chamber 4. A special key 23 is inserted into a slit 20 and pushed upwards until one hinged end 26 causes the withdrawal of a catch 32 from a toothed wheel 12. The key ends 26 and 25 are then divided by spring-loaded fingers 28 and the rack 25 through a pinion 19 rotates the wheel 12 and with it the key 3 which is clamped to the wheel. Withdrawing the key 23 reverses the motions. A spring 39 and a flexible wire 41 assist the locking operation until the wheel stop 37 is reached. When the safe key 3 is removable, insertion of the key in the keyhole 2 is prevented by three covers 48, 49, 50, Fig. 3, which cover a sinuous slot 44 and its extension 45. A separate key pushed into a slit 46, Figs. 3 and 9, bears on three rods 59 and through three hinged levers 53 causes the covers 48, 49 and 50 to slide aside and expose the sinuous slot 44. The end of the safe key 3 can then be inserted in the slot 45 and slidden along the slot 44 to a guide piece 65 which positions the key for entry into the safe lock. To replace the covers 48, 49 and 50 the separate key is withdrawn and springs 58 move the levers 53 back to their original positions. A modified means of sliding the plates 48, 49, and 50 is described in which a flexible key inserted into the slit 46 engages the ends of three bent rods, and turning the rods in their pivots causes the other ends of the rods to slide the plates 48, 49 and 50 aside and expose the sinuous slot. These covers are also returned to closing position by means of springs.

Abstract: 203,171. Telford, J. W., and Howcroft, H. S. Aug. 22, 1922. Lift cages and doors, locking and unlocking and operating.-A sliding bolt D in one extreme position, Fig. 4, passes through a projection E on the collapsable gate H of the cage and in the other, Fig. 1, prevents the movement of the handing chain A since the bar B is then in the narrow slot c<1> of the block C through which the enlargements b cannot pass. The protection E is similar in shape to the key of a tumbler barrel lock and when it enters the slot f in the barrel F it pushes out the pins f<1> until they are flush with the surface of the barrel. If the projection is then turned through a quarter of a revolution, the barrel F is turned until a transverse aperture therein coincides with a similar aperture in the statonary barrel F' which is in alignment with the bolt. The bolt D can then be moved to lock the gate and release the handing chain.
