Abstract: 531,642. Decorticating fibrous leaves. COMPANIA GENERAL DE EXPLOTACION DE FIBRAS SOC. ANON, and UNZUETA, L.S. July 20, 1939, No. 21136. [Class 120 (i)] Fibres are obtained from the leaves or stems of soft plants, e.g. agaves, by subjecting the plants to a crushing operation and transverse cutting by passing them longitudinally between pairs of fluted rollers and then removing the pulp by subjecting first one side and then the other side of the material while supported against indiarubber or like soft and resilient material, to the action of rollers provided with hackling pins or rubbing or rasping elements. As shown, the leaves &c. are drawn longitudinally from a table 10 by the pairs of fluted crushing rollers A, A<SP>1</SP> and pass between one or more indiarubber rollers C and drums B provided with teeth or pins to the depulping rollers D, D<SP>1</SP> which are arranged to act upon opposite sides of the material while it is supported by rollers C<SP>1</SP>, C<SP>11</SP> of indiarubber or other soft flexible material : the fibres are delivered by a pair of rollers F. The depulping rollers may be provided with flexible steel sheets disposed longitudinally thereof and after depulping the material may be subjected to the rubbing action of a roller provided with radial blades. More than two sets of depulping rollers may be provided, the axes of the rollers of the second set may be arranged in a plane at an angle to the plane containing the axes of the first set, and the plane of the axes of the second set may be at an angle to the plane containing the axes of the rollers F.

[Also in Division B8] Six food tray containers 23, for delivery by lift cage 10a to six respective floors of a building, are supported on shafts 21 located at equal intervals on endless conveyer chains 14 driven by a reversible electric motor 20 while the cage 10a is in motion to bring the required container 34 to its unloading position in the cage. When the cage is stopped, the container 34 (Fig. 4) is unloaded by means of two arms 37 each keyed on a stub axle 36 journalled in the cage frame 30 and rotatable by means of chain wheels 40, 42 of an electric motor (not shown), and each carrying a roller 39 which, when the arms are pivoted upwardly from their rest positions 44, engages a projection 46 on the side of the container to lift it off its shaft 21 and deposit it outside the cage on a trolley (not shown) whereupon further rotation of the arms 37 to position 50 causes them to disengage from the projections 46. Reverse operation of the mechanism is employed to load a container. Interlocking means may be provided to prevent movement of the chains 14 unless the arms 37 are in parked position 44, and means may also be provided for effecting automatic opening of the landing door on arrival at any floor level at which the cage stops and for giving a visual or audible signal.

Abstract: 359,452. Recording rest or motion of engines. WADE, H., 111, Hatton Garden, London.-(Deuta-Werke vorm. Deutsche Tachometerwerke Ges. ; 25, Oranienstrasse, Berlin.) July 15, 1930, No. 21414. [Classes 106 (iii) and 106 (iv).] A recording instrument, especially for vehicles, having a pendulum transmitting its vibrations to a marking implement is characterized in that. additional means are provided which act upon the marking implement to produce different markings according to the state of rest or motion of a motor plant. The pendulum 28 transmits its vibrations. to a stylus 26 recording in succeeding circles on the clock-driven record sheet 58 in the manner described in Specification 328,816, [Class 106 (iii), Fares &c.]. The nipple 45 is connected with the intake of the motor and when the motor is running a suction is created in the diaphragm bellows 44, to cause the lever 46 to depress the bolt 46<1> and make it contact with the wedge 47 of the sliding bolt 40 engaging the free crank end of the stylus 26 which is thus turned through about 90‹ with its recording knife edge so that the thickness of the line traced is altered. In the modification shown in Fig. 2a the spring-pressed stylus 26 is normally kept out of engagement with the record sheet 58 by the arm 51 of the spring-pressed stirrup 50 but is allowed to come into contact with the record sheet when the motor is running and the bellows 44 contracted to cause the lever 46 to depress the bolt 48 and stirrup 50. An audible visible signal is given at a predetermined time, by the clock-driven arm 59 having a yielding end 59<1> which engages the arm 63 and oscillates the roller 61 to bring the pins 62, 671 into electrical contact. As an alternative a common alarm clock mechanism may be actuated by the arm 59. A knife 76 is adapted to co-operate with a slot 75 of the supporting plate 251 to slit the record sheet when opening the instrument, the slit extending into the path of the stylus. The instrument is contained within the cover 1 and back plate 3- closed by a lock 82.

Abstract: 259,191. Bragg, C. S., and Kliesrath, V. W. Oct. 3, 1925, [Convention date]. Fluid-pressure.-A pneumatic relay for actuating brakes of motor vehicles, steering gear of land water or air motor vehicles &c. comprises a pair of closed cylinders 2, 102, the pistons 3, 103 of which are connected the piston 3 having a reversing valve with connections to a source of suction and of higher pressure. This piston can be subjected on either side to pressure fluid; one side of the other cylinder is connected to the corresponding side of the valved cylinder by a pipe 107, while the other side is always open to suction through a pipe 108. More than two cylinders may be used. The rod 105 of the auxiliary cylinder actuates the brake or other mechanism, for example through a piston 203 of an hydraulic cylinder connected by piping 210 to the brake system. An oil reservoir 214 is connected with the cylinder through a check valve. The hub 10 of the piston 3 contains valve chambers each containing a pair of conical valves 40 - - 43 separated by springs. The inner valves control communication of the valve chambers with a suction space 17 open through an apertured tube 20 with a suction device such as the intake manifold of an internal combustion engine. The ends of the cylinder 3 are open to the valve chambers through apertures 34, 35. The tube is also operable, for example by a foot lever with spring retraction and a stop; it passes through the valves and is fitted with collars to limit their motion. It is fitted with a plug 22 and may be provided with apertures 22a for the admission of air by way of valve 43. At its further end it is fitted with a collar held loosely within a collar 106 connecting the piston rods of the two pistons. The brake &c. may thus be actuated manually in case of power failure.

Abstract: 192,358. Dachary, C., and Viguier, L. Jan. 28, 1922, [Convention date]. Lighting systems; switching systems.-An arrangement for the safe handling of hand con. tact devices or plug connections in high tension circuits comprises an interrupter in the high voltage circuit associated with the removable elements in such a way that none can be removed without the prior opening of the interrupter. Fig. 1 shows a train with a high voltage circuit T, detachable coupling cables C between the cars and an electromagnetic interrupter I. A low voltage circuit t is carried through the train and includes detachable leads c and the closing coil of the interrupter I. The cables C and leads c have coupling elements N, n respectively so interrelated that an element N must be in place before the associated element n can be inserted and the former cannot be removed until the latter has been uncoupled. According to an arrangement, Figs. 2, 4, the elements N, n are fitted into sockets M, m provided with a shutter V which effects the required interlocking. A hinged cover E, Fig. 5, completes the low voltage connection to earth on the end car by a projection U engaging the contact in the socket m. In a modified construction shown in Fig. 7, an abutment K on the lid of the sorket M actuates, through a projection O on a lever H, a contact making device P to open the circuit t when the lid is raised to insert or remove the element N; the plug N is retained in position by co-operating projections Q, U. The low tension elements may carry additional contacts for a lighting circuit. To avoid using special couplers with extending vestibule cars, duplicate sets of sockets are placed at each side of the end panels of such a car and the low voltage sockets each have two contacts v, v<1>, connected as shown diagrammatically in Fig. 10. Sockets not engaged by couplers c are covered with lids carrying connectors v<1>, which couple together the two socket contacts.
