Patent GB-721615-A (GB)
Title: Improved manufacture of terpenes from í¸-carene
IPC: C07C5/31
Filed: 1952-04-30
Abstract: D 3-Carene is converted into monocyclic terpenes by passing the vapour at elevated temperature over a catalyst consisting of a porous solid adsorbent having a surface acid character and free from metals of Groups 1, and 5 to 8, or their compounds.  The contact time is generally at most 1 minute and may be controlled by addition of inert gases.  Temperature is generally from the boiling point of the carene (171 DEG  C.) up to 350 DEG  C. and should preferably not exceed 500 DEG  C.  Temperature and/or contact time may be increased as catalytic activity falls. They may be decreased by adding small amounts of vapour or gas of polar substances forming addition compounds with the carene, e.g. hydrochloric acid or steam.  Thus dipentene hydrochloride may be added to the carene before vaporization.  The catalyst may be regenerated by burning off in air at about 500 DEG  C. or, in the case of active carbon, by steaming. The carene may be obtained from sulphate turpentine.  In examples, fractions containing 50 to 80 per cent D 3-carene are vaporized, in one case with dipentene hydrochloride equivalent to 0.1 per cent HCl, and passed, alone or with CO2, over commercial silica gel, active carbon or activated alumina of varying mesh sizes at temperatures from 205-450 DEG  C. and contact times of 28-0.8 seconds illustrating the need for higher temperatures and/or times with coarser-grained catalysts.

Driving-gear for mangles and wringers.-In a mangle or wringer, means are provided for driving the lower roller shaft from the handwheel either directly or indirectly through reduction gear. In Fig. 1 the handwheel A is loose upon the lower roller shaft B and, in the position shown, the pinion a<1> integral therewith drives the shaft through spur reduction gear, the final wheel of which is shown at E. The handwheel is held in this position by the engagement of a forked lever c in an annular groove a between the hand-wheel and the pinion a'. The lever is pivoted on a projecting pin C and is provided with a handle c<1> so that when it is withdrawn from the groove a, the hand-wheel may be moved to the right so that recesses a<2> in its hub are engaged over teeth b rigidly secured to the shaft B. The handwheel is locked in this position by the engagement of the lever c over the boss a<3> of the pinion a<1>. In a modification a spring-pressed forked plunger carried in a lug on the hand-wheel abuts against the teeth b to lock the hand-wheel in the indirect drive position, or against the outer face of the clutch member to lock the hand-wheel in the direct drive position. A slotted plate working over a. bolt having a wing nut and carried by a spoke of the hand-wheel may be substituted for the spring pressed plunger. In a chain driven machine, Fig. 6, the sprocket wheels a<6>, K are formed with annular grooves a<5>, k, which are engaged by a plate L having an operating lever handle l<1> and slidable along a stud l projecting from the machine frame D. The stud is provided with notches l<4>, l<5> to receive the lever l<1> for locking the gears, the lever l<1> passing through a slot l<2> in the boss l<3> of the plate L. As shown the gears are locked in the direct drive position, the hand-wheel A engaging the teeth b fast on the roller shaft B and the clutch M, M<1> between the sprocket wheels K, k<2> of the reduction gear being disengaged. When the plate L is moved to the left it takes with it the sprocket wheel a<6> and the integral. hand-wheel to disengage the clutch teeth b and simultaneously the sprocket wheel K is caused to slide along its stub shaft k<1> so that the clutch members M, M<1> are caused to engage, whereby the sprocket wheel k<2>, which also is loose on the stub shaft k', drives the final sprocket wheel k<3> of the reduction train fast on the shaft B. Instead of the lever l<1> being carried by the sliding plate L it may be pivoted on a lug projecting from the machine frame, in which case one end of the lever is provided with a rounded head engaging a recess in a boss on the plate, whilst the other end of the lever engages one or other of two notches in another lug projecting from the machine frame.

Abstract: 224,496. Lindstr÷m Akt.-Ges., C. Nov. 10, 1923, [Convention date]. Sound magnifying and directing appliances. - A gramophone sound-conduit is made of hard highly elastic material such as steel, has a smooth interior surface which prevents any frictional resistance to the sound waves, and is rendered non-resonant by making the weight of the walls large in proportion to their surface area. The necessary increase in weight may be obtained by using thick walls or, without substantial increase in the thickness, by the addition of strengthening ribs on the outer surface. Fig. 2 shows one arrangement of such ribs c, d. The conduit may be built up in several sections with the joints, which may be parallel to the longitudinal axis of the conduit or at an angle thereto, covered by the strengthening ribs. The sections mav each have a different natural frequency, the sections being joined homogeneously by welded seams which also act as strengthening and weighting members, the seams being either longitudinal, transverse, or a combination of both. The inner surface of the conduit may be coated with a smooth unoxidizable material, for example, enamel.
