Abstract: 347,221. Producing medicinal vapours. MENGERING, F., 11, Goethenstrasse, Magdeburg, Germany. Jan. 23, 1930, No. 2424. [Class 81 (i).] Vaporizable medicaments are extracted from the raw materials containing them, for example, pine, fir, or spruce needles, by passing therethrough a stream of vapour or gas while at a temperature above 100‹ C., the medicated vapour or gas being used immediately as an inhalation or vapour bath. As shown in Fig. 1, the raw material is placed in cylindrical vessels 5 connected in series by pipes 6 and enclosed in a pressure chamber 3, having a safety-valve 12. Steam under pressure is first admitted to the chamber 3, through a pipe 10, and withdrawn, together with any condensation through a pipe 13. When the material is sufficiently heated, cocks 15, 14 are manipulated to pass the steam through the vessels 5 and thence to a pipe 9. Alternatively or in addition a gas, such as air or oxygen may be admitted, in a hot or cold state, through a pipe 16. The extraction vessels 21, Fig. 3, are of inverted U-shape and are enclosed in a pressure vessel 17 containing water heated by an electric immersion heater 23 or the like. Gas or steam is passed through the vessels 21 in series from a pipe 19 and delivered through a pipe 20. Steam is also admitted to the vessels from the vessel 17 through a valve 22 opening at a predetermined pressure. A. safety-valve 25 and safety devices, cutting out the heater on excessive rise of pressure and temperature respectively, are also provided. Specifications 17500/00, [Class 81, Medicine &c.], and 13801/13, [Class 81 (i), Disinfecting &c.], are referred to.

Abstract: 555,730. Wet-separating. HALLIMOND. A. F. Feb. 26, 1942, Nos. 2504/42 and 943/43. [Class 82 (ii)] In the flotation separation and classification of particles, a stream of bubbles, preferably of air, is supplied by a jet through a shallow dense layer of the material to be treated at the bottom of a bath of liquid and are guided by an inclined surface extending towards the surface of the bath, two or more other surfaces below and near the first surface separately catching particles partially lifted and those particles carried by the bubbles until they burst. In one form of apparatus, Figs. 2. 3, the pulpy material to be treated is fed by a hopper 11 into the bottom of a groove 12 along which it is caused to flow by the action of a rotating cylinder 13 provided with ribs 14. Air is supplied through jets 16 under a layer of material covered with a loose pad and fed from a manifold in which a constant pressure is maintained. The rising bubbles are guided by an inclined surface 22 and break near the surface of the liquid, the lifted material falling on to a surface 23 by which it is guided and discharged into a hopper not shown. Material partially lifted falls upon a surface 24 provided with ridges 27 and is guided back into the groove 12 for further treatment, or if desired some of this material may be collected by a surface 25 provided with a curved portion 26. The space between the guiding surface may be divided into compartments by divisions 28, and the chambers formed by the guiding surface may be closed by ends 29 fitted to the groove 13 at 30. In a second form the baffle plates may be placed across the groove instead of along them. In another form the apparatus comprises a tube with an open lower constructed end containing a compressed fibrous pad gently pressed into the end and in which the material is placed. One side of the tube forms an inclined surface up which the bubbles rise to the top of the liquid and the released particles fall down the other side of the tube and are entrained in a side tube.

Title: Improvements in locks
IPC: E05B63/12
Filed: 1925-02-04
Abstract: 247,006. Marks, E. C. R., (Keil & Son, Inc., F.). Feb. 4, 1925. Locking sliding latches; locks, with bolts interlocking with staples; night latches; lockmechanism, slidertype; bolts; latches, sliding.-A lock has one or more bolts which are projected into a staple and then rotated to interlock therewith, and one latch which is locked against retraction when the bolts are shot, and which locks the bolts against retraction when held in the withdrawn position by a finger catch. The latch and bolts are operated from the outside by a common revolving-barrel mechanism but have separate handles for operation from the inside of the door. Fig. 2 shows the latch 27 shot bv its spring and the bolts 20, 21 in the withdrawn position. To shoot and turn the bolts from outside, the key 1 is inserted in the revolving-barrel mechanism and turned, rotating a connector-bar 2 and an arm 4. This causes a stud 5 on the arm 4 to engage a rib 6 on a vertically sliding plate 7 to lift the plate and raise a flange 11 thereon out of engagement with the'stop 9 on the casing. Further turning of the key causes the stud 5 to engage an inclined rib 62 on the horizontally sliding plate 13 upon which the slide 7 is mounted, moving the plate 13 to the left. This plate carries projecting arms 14, 15 having studs 16, 17 respectively at their ends to engage spiral slots 18, 19 in the bolts 20, 21. As the plate 13 is slid forward by the key, the studs 16, 17 push the bolts, mounted on a sliding plate 8, forward to shoot them into the staple 64. When the bolts are shot, a cross piece 12 in the plate 8 abuts on a rib 42 on the latch 27, stopping further forward motion of the plate 8 and bolts. As the key is further turned, the plate 13 travels onward until the arms 14, 13 engage the end of the casing, the studs 16, 17 travelling down the spiral slots 18, 19 rotating the bolts through 90‹ into the position shown in Fig. 34, projections 22, 23 on the bolt ends then being out of alignment.with the corresponding slots in the staple 64 so that the bolts cannot be retracted by simple linear movement. Reverse turning of the key withdraws the bolts and when they are completely withdrawn, continued rotation of the key withdraws the latch, the stud 5 striking the flange 44 of the pivoted lever 43 and causing this lever to rock a lever 47 which engages a flange 30 on the tail of the latch. The bolts are operated from the inside by a handle 26 which turns a disc 24 provided with an eccentric pin 25 which engages a hole in the slider 7. The latch 27 is operated from inside by a handle 40 which is provided with the double follower 38 engaging in a suitable slot in the shank 28 of the latch. A catch 32 with a finger piece 34 projecting outside the casing, can lock the latch in the shot or withdrawn positions. The bolts can he made of hardened steel, or with a hardened steel core to prevent release by sawing through them.
