Title: Preparation of tertiary-butyl-hydroquinone
Inventor: YOUNG DEWALT SECRIST
IPC: C07C37/16
Filed: 1954-07-19
Abstract: Tert.-butyl-hydroquinone is prepared by reacting hydroquinone with isobutylene or tert-butyl alcohol in the presence of an aromatic hydrocarbon containing 6-8 carbon atoms and phosphoric acid at an elevated temperature with agitation.  The amount of phosphoric acid used is preferably from about 1 to about 6 times the weight of hydroquinone employed.  The hydroquinone and tert.-butyl alcohol or isobutylene are preferably used in approximately equimolecular amounts.  The aromatic hydrocarbon, usually toluene or xylene, serves to remove the mono-tert.-butyl derivative from the hydroquinone-catalyst phase and thus protect it from further alkylation.  The reaction is generally conducted at reflux temperature and the water formed in the reaction when tert.-butyl alcohol is used is removed by azeotropic distillation. Tert.-butyl-hydroquinone is used for the stabilization of oils and fats.  In examples, the process of the invention is carried out batchwise, in successive batches or continuously.  In the batchwise process: (1) hydroquinone, toluene or xylene and phosphoric acid are mixed and heated while tert.-butyl-alcohol is added slowly, the aromatic hydrocarbon layer is separated from the acid layer (which may be re-used) and the tert.-butyl-hydroquinone obtained therefrom; (2) as in (1) but using isobutylene and xylene.  In the successive batch process hydroquinone, phosphoric acid and toluene, are mixed and refluxed, tert.-butyl alcohol is added slowly (further hydroquinone being added at intervals during this addition), the toluene and acid layers are separated, the toluene layer is cooled to crystallize tert.-butyl hydroquinone and then filtered, the filtrate and the phosphoric acid being used in successive batches.  In the continuous process, equal volumes of toluene and phosphoric acid are heated to boiling point in a cylindrical reactor and well stirred at the bottom (i.e. the acid layer) only, a mixture of tert.-butyl alcohol, toluene and hydroquinone is fed in at the bottom of the reactor, the toluene solution of the product being drawn off at the top of the reactor, the tert.-butyl hydroquinone separated and the toluene recycled.

Filed: 1963-05-27
Abstract: 1,094,643. Semi-conductor devices; waveguide switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 11, 1964 [May 27, 1963], No. 21120/63. Headings H1K and H1W. A microwave variable attenuator comprises a section of waveguide containing a plurality of PN junction semi-conductor elements of the type disclosed in Specification 995,839, spaced apart along its length. The wafers of the elements are arranged parallel to one another. Bias voltage is applied between the electrodes of each element by means extending to the outside of the guide. The wafers may be disposed in a plane parallel and close to the narrow wall of a rectangular guide or in a plane inclined at an acute angle to the waveguide axis. Alternatively, they are arranged along the length of the guide in parallel pairs the spacing of which progressively increases. Finally, they may form part of the common wall of two parallel waveguides for use as a total coupler to enable high energy level waves from a transmitter to proceed along one guide but to switch received or reflected radiation at a lower energy level to the second guide and thence to a receiver. When elements of the form shown in Fig. 4, with alternate interconnected rectifying and ohmic electrodes 9, 10 on each side of the control axis 8 are used, connection to the outermost electrodes 9 are made through the waveguide walls directly via metal layers 11 or via spring clips pushed over the edges of the wafers.

Title: Improvements in or relating to apparatus for enumerating and indicating the number of available seats on the decks of passenger carrying vehicles
IPC: G08B5/22
Filed: 1946-07-17
Abstract: 618,465. Counting-apparatus checking fares. COLT, G. H., and CHAPPELL, A. J. July 17, 1946, No. 21433. [Classes 106 (i) and 106 (iii)] Relates to means for indicating the number of vacant seats on the upper deck of a passenger vehicle, controlled from three consecutive stair treads operating electric switches, the lowest stair switch adjusting selector mechanism for subsequent negative movement of the indicating means, and the highest stair switch adjusting the mechanism for subsequent positive movement, the actual movement of the indicator by pawl-and-ratchet means being caused by closure of the middle stair switch. According to the invention the selector mechanism includes two solenoids energizable by depression of the highest and lowest stair treads respectively, each controlling a two-position contact member, which member prepares a circuit for operating the pawl-and-ratchet mechanism in one position, and in the other position, prepares a circuit for the other solenoid Depression of a tread E<3> against a spring F<3> closes contacts T<3>, thus connecting a source of current Y via bridged contacts T<2> to a solenoid L<2> causing its armature C<2> to be pulled to the right against a spring S <5> in a dashpot H<1>. A contact member V<1> is moved over during this movement to bridge contacts T<8> and so prepare a circuit for a solenoid L‹ which is energized when depression of the middle tread E2 closes. switch T<4>. Energization of the solenoid L<5> causes a spring-pressed pawl P<o> pivoted at the end of its armature C<5> to step on a numbered disc N which indicates that an additional seat is available. A passenger going up the stairs operates the system in a similar but negative manner, the solenoid L' causing reverse rotation of the disc N in this case. To avoid incorrect operation, magnetic brakes Z<1>, Z<2> becoming operative when the solenoids L<5>, L<4> respectively are energized, prevent their associated armatures C<2>, C<3> from returning to inoperative position as long as the middle stair tread switch T<4> is closed.

Title: Bobby pin carding machine
Inventor: WEAVER RUTH KAHAN
IPC: B65B15/02
Filed: 1953-08-04
Abstract: 734,559. Carding hair grips. GAYLORD PRODUCTS, Inc. Aug. 4, 1953, No. 21509/53. Class 94 (1). Hair grips 7 are transferred from an oven wire 47, on which they are mounted for heat treatment, japanning, drying &c., on to a flat flexible card 4 with slits 6 to receive the pins, by a machine provided with supports 72, 74 for the ends of the oven wire, front card holder mechanism 76 with jaws 87, 88 to grip the front end of the card, rear card holder mechanism 77 with jaws 101, 89 to grip the rear end of the card, and means for moving the card holders relatively to the oven wire to transfer the grips in groups from the wire on to the card. An oven wire 47 loaded with seventy or eighty grips 7 is first manually positioned between fork members 64, 66, Fig. 2, pivoted between arms 51 slidably mounted in the frame 14 of the machine. The fork members have wedge-shaped prongs 67, Fig. 8, which divide the grips on the wire into groups, Fig. 9, and the fork members are turned manually into line with the arms 51 which move inwardly to transfer the oven wire 47 from the forks 64, 66 on to the supports 72, 74 and then move outwardly to strip the oven wire from the fork members. The cards 4 are transferred from hoppers 13 to the front and rear card holders 76, 77 by sucker fingers 27 and a frame 23 moved by cams so that on release of the suction a card drops on to the card holders when in their loading position, Fig. 2. Cams cause the jaws to grip the ends of the card and the rear card holder 77 is moved slightly towards the front card holder 76 causing the cards 4 to buckle adjacent the slits 6 as shown . in Fig. 7 to facilitate insertion of the legs of the grips through the slits. This movement is stopped when pins 125 on the rear card holder engage adjustable screws 126 on the front card holder. The front and rear card holders then move as a unit in a counterclockwise direction to cause the cards 4 to move relatively to the grips 7, the open ends of which are directed towards the card slits 6 by guide grooves 109 formed in a guide bar 108, causing the lower uncrimped legs of the grips to be threaded through the slots 6. After the grips have thus been partially mounted on the cards the rear card holder 77 is brought to rest against stop members 123 and the clamping jaw 101 is raised to release the cards from the rear card holder. The front card holder continues its counterclockwise movement alone and pusher fingers 153 cause the grips to be fully mounted on the cards as shown in Fig. 11. Continued movement forces the fingers 153 upwardly and the grips are withdrawn by movement of the cards away from the fixed oven wire 47, which is then manually removed from the machine. The clamping plate 87 is then moved out of engagement with the plate 88 to release the front end of the card, and a permanent magnet 162 holds the grips and card against an aluminium plate 161. The magnet is then moved away allowing the loaded card to drop into a hopper 191.
