[Also in Division B1] Apparatus for use in the continuous production of pulp from lignocellulose-containing material, e.g. wood chips, grass, straw etc., comprises three vessels of which the second (12) is inside the third (14) and communicates with it at the top. The first vessel (10) has an intake (16) for the material and may have an inlet (20) for steam at low pressure to displace air from the pores or interstices of the material. It is connected at its base with the base of the second vessel by means of a channel, such as tubes 24 and 26, containing a screw conveyer (28) that co-operates with at least one counterpressure member (32) to compress the material before release of the pressure below the level of impregnating liquid supplied to the second vessel through an inlet (54). The impregnated material is cooked in the third vessel. As shown, the second and third vessels are heated by steam admitted through the pipe 59, and the cooked material removed by screw-conveyers 64. The level of impregnated material in the third vessel and of liquid in the second is controlled by devices 62 and 58. A jacket 40 may be provided to receive water and steam pressed out of the material by the screw press 28, without loss of pressure. In another embodiment (Fig. 3, not shown) the second vessel extends nearly to the bottom of the third, and its lower part is surrounded by the impregnated material being cooked.

Filed: 1934-01-04
Abstract: 422,735. Electrical musical instruments. NERNST, W., 18, Neue Wilhelmstrasse, Berlin. Jan. 4, 1934, No. 356. [Class 88 (ii)] In order that an electrical pianoforte without a sound board may yield a tone similar to that of the ordinary piano forte, one or each bridge is made capable of vibrating but not perceptibly tone-producing, while at the same time the vibrations in the bridge are damped. A device comprising a resilient part absorbing string vibrations and a porous or soft material absorbing string energy may be arranged between the bridge and the frame. In Fig. 1<a> the metal bridge-bar St rests on a resilient wooden or metal box K filled with porous or soft material F as felt or cork ; preferably a cork piece Z further damps the vibrations. In Fig. 2 (not shown), the box K is replaced by a U-shaped member. In Fig. 3 (not shown) the bar St rests on a tall member of wood or cork combining both the resilient and the damping actions. In Fig. 4, the bridge-bar rests on laminµ of steel C alternating with laminµ of leather D, free at their ends in a wooden holder Ha ; or the laminµ may be arched and supported at their ends (Fig. 5, not shown). A wooden plate or plates, or plates of hard paper or whalebone may be used. Means such as a sliding part T, Fig. 1<a>, may be provided to prevent the box K from vibrating, so that when desired the string may vibrate for a longer period ; in such circumstances an improved organ tonecolour is obtained by connecting condensers in parallel to the microphones. Or the organtone may be obtained by the use of a separate string for each note, supported on a rigid bridge. Specification 414,352 is referred to.

Title: A system for automatically varying the braking action upon motor and other vehicles
IPC: B60T8/24
Filed: 1924-01-07
Abstract: 209,433. Vazel, E. Jan. 6, 1923, [Convention date]. Braking; controlling different functions by same handle or lever.-Relates to a braking system in which a single operating member applies brakes to all four wheels, and comprises means connected to some part of the steering- gear and interposed between the operating member and the front wheel brakes so that the braking effect on the front wheels is varied according to the direction given to these wheels by the steering-gear. The brake pedal 1 is connected to the rear brakes (not shown) by a member 2 and to the front brakes 4 by a jointed rod 7, 8, an equalizing lever 6 and rods 5. The rod 7, 8 is in two parts pivoted at 9, to which point is connected a link 10 controlled' by the steering-shaft 14. When the parts are in the position indicated in full line, the pedal 1 act equally on the front and rear brakes, but when the steering gear is operated so that the parts are as shown in broken lines the rod 7, 8 is shortened and the brakes on the front wheels can only be applied to a lesser degree or not at all. Instead of the jointed rod 7, 8 a cam mav be used between the pedal and the equalizing lever, or an automatically adjustable member such as a cam or an inclined plane may be interposed between each brake rod 5 and the corresponding front-wheel brake so that when the steering-gear is operated the possible braking effect on the two front wheels is varied, e.g. braking may be possibla on one wheel and not on the other. In the construction shown in Fig. 2 the steering-wheel brake cam 4' is rotated through a quick-pitch screw connection 6<1>, 7<11> by an arm 3 on a sleeve 8<11> freely supported by a rod 9<11> universally connected at 10<1> to the chassis. The sleeve 8<11> is connected by a ball-and-socket joint 14<1> to a rod 15<1> sliding in a tube 16<1> ball-jointed' at 17 to the chassis. The rod 15<1> is itself connected bv a ball-jointed link 20 to an arm 22 carried by the stub-axle 2<1> of the steering wheel. When the brake-operating arm 3 is rotated the sleeve 8<11> rotates the cam 4<1> in the ordinary manner, but when the stub-axle turns for steering the arm 22 moves about the steering pivot and draws the rod 15, and with it the sleeve 8", nearer thereto. The axial movement of the sleeve rotates the cam 4<1> to a certain extent and releases the brake if it is already applied. This construction is not claimed.

Abstract: 488,567. Coking processes ; drying coal &c. SCHUFTAN, P. M. Jan. 8, 1937, Nos. 631 and 35468. [Class 55 (i)] [Also in Group XIII] In the drying, or high or low temperature distillation of solid fuel such as coal, shale, peat, or wood, the fuel is subjected in a vertical shaft to internal heating by the sensible heat of the combustion products of a gaseous or liquid fuel with oxygen, or a gas richer in oxygen than air, without combustion of the fuel itself. Water in the form of liquid or vapour may be introduced into the shaft to control the temperature of the combustion products. A suitable fuel is water gas which may be obtained by steaming the hot coke residue, but hydrogen and oxygen from the electrolytic decomposition of water may be used, or tar obtained from the process. A shaft 1 contains the fuel the residue from which may be discharged continuously by an extractor 4 into a hopper 5. Pipes 9, 10, and 11 supply oxygen, liquid or gaseous fuel, and steam or water spray respectively to a combustion chamber 7, from which the hot gases enter the shaft through ports 8. Inlets 12 for steam or water spray are arranged at the bottom of the shaft at various levels. A gas offtake 3 is provided at the top. With high temperature carbonization, the temperature of the hot coke may be sufficient to provide the whole of the water gas which is burnt with oxygen at the bottom of the heating zone, in which case the combustion chamber 7 may be dispensed with. Intermittent working may be used.
