[Class 23] Metal articles are dried in a centrifuge a through which a current of warm air from the heater u is drawn by a fan r. The basket is made of wire mesh, and the annular boss d carries a pin g which rests in a slot h in the end of the shaft b and forms a driving connection. The sheet metal casing has two parts k, l and the upper part k is arranged partly within the lower part l so that a small annular gap n is left between them. The fan r is placed in the lower part. The casing cover x carries an elbow pipe y connected to a second elbow z which is slidably and rotatably mounted in the pipe w from the heater u. The upper friction surface of a collar 4 is held by a spring 5 in engagement with the framework so that the shaft b is normally held stationary. When however the treadle 3 is depressed, the collar is moved so that its lower friction surface engages a similar surface on the pulley 8 so that the machine rotates. The liquid thrown off the articles passes to the casing part k and the drain q while the fan r draws warm air through the apparatus and discharges it through the gap n and perforations s in the casing part l.

IPC: B61G3/22
Filed: 1921-06-16
Abstract: 179,456. Redington, T. F. June 16, 1921. Couplings, automatic. -An automatic coupling comprises complementary heads each provided with a hook face engageable with a pivoted catch operated by a tumbler on collision of the coupler heads, and a wedge-shaped locking-member mounted eccentrically on a manually-operated releasing-spindle which drops into engagement with a corresponding wedge face on the catch in coupling. Each coupler head has a hook 2. Fig. 4, pivoted catch 3, tumbler 6, and a locking-wedge 10 mounted eccentrically on a spindle 9 connected to a manually-operated weighted lever 12. The connection between the spindle 9 and wedge 10, Fig. 3, provides lost motion by means of tappet 13 on lever 12 and lug 14 on the wedge. In uncoupling, the lever 12 is moved by hand, the wedge 10 withdraws laterally due to its eccentric mounting on the spindle 9 until tappet 13 contacts with the lug 14, the wedge then revolves to its " set to couple " position where it rests on the top of catch 3 and finally to its " not to couple " position in which the wedge is prevented from falling by the position of the weighted lever 12. When in the " set to couple " position, shown in dotted lines in Fig. 3, the wedge 10 rests by gravity on the toe 11 of the catch, the cam-surface 5 of the tumbler protruding through a recass in the jaw of the coupler head. On collision, the part 5 is struck by the point of the opposing coupler head and the finger 7 revolves the catch 3 into engagement with the hook 2. The wedge 10 then falls by gravity into engagement with the wedge surface 11 of the catch and locks the coupler.

Title: Improvements in electro-magnetic locking devices for use on railways
IPC: B61L19/16
Filed: 1928-06-09
Abstract: 291,806. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Hayles, W. H., Baker, E. W., and Saxby & Farmer (India), Ltd.). June 9, 1927, [Convention date]. Electrically controlled fastenings.-In an electromagnetic locking mechanism for a sliding member 1, the armature 6 of the electromagnet 8 is also the locking bolt and is carried by the slide. The bolt 6 is pivoted on a pin 5 and its movement is limited by another pin 7. In the normal position of the slide the bolt is so situated with respect to the magnet-poles 9, 10 that a small current in the windings is sufficient to draw the armature. If the slide is moved, the armature cannot be lifted subsequently by the magnet. If the magnet is energized and the slide then moved, the projection 12 and upper edge of the bolt are kept against the pole 9 and the heel 14 of the bolt clears the stop 11 on the frame. On restoring to normal, the projection 12 engaging the pole 9 ensures replacement of the bolt to prevent a further operation of the slide without re-energization of the magnet. A series of bolts may be mounted on the slide to lock the slide in different positions on forward or backward motion, and the parts may be so proportioned as to be reversible.

Title: Light pens
IPC: G06F3/038
Filed: 1976-06-11
Abstract: 1529693 Light pens SCIENCE RESEARCH COUNCIL 11 June 1976 [23 April 1975] 16884/75 Heading H4T A light pen for operating with the screen of a cathode ray tube is provided with a switch which controls a signal, the signal being multiplexed with the video signal and the power supply on a single conductor forming part of a light-weight lead for the pen. The tip of the pen containing a photocell BPY77, may be mounted together with the video amplifier PA on a circuit board (not shown) which is movable against spring pressure to operate the switch TC mounted with the other circuitry on a fixed board. The output of PA is fed to the lead through a capacitor Cl and resistor R1. Input current flows through the parallel combination of transistor TR and a Zener diode to a groundedanode Zener diode the voltage drop across which provides the (constant) supply voltage. The transistor TR conducts when switch TC is closed. Opening and closing of the switch causes a change in voltage across the line which is smoothed by a capacitor between the base and collector of the transistor. The video signal has a rise time about 1000 times faster than the switch-controlled signal. The amplifier is shown in detail in Fig. 2. For providing current feed, the base of transistor TR2 is clamped by Zener diode Dl so that it acts as a constant-current source. Video signals are separated from switch signals by the HP filter C7, R7. The inverted output from IC3 feeds half of a line driver IC2 producing positive going output pulses, the non-inverted output of IC3 being used to retrigger the monostable section of IC3. The switch signal is separated by LP filter C1, R4. The signal is shaped by IC I and fed to the second half of the line driver IC2 which produces a normally high output, going low when the switch TC is opened. The switch signal may be used to produce a modification of that part of the image seen by the pen, or it may be used to activate the pen e.g. by providing a single white frame which momentarily increases the illumination. A further switch, operated by separate means, may be coupled to the circuit via resistance R5 and transistor TR1.

Title: Method and blade arrangement to reduce the serpentine motion of a mass particle flowing through a turbomachine
IPC: F01D5/14
Filed: 1971-05-25
Abstract: 1306891 Axial-flow turbines and compressors BROWN BOVERI & Co Ltd 25 May 1971 [27 May 1970] 16992/71 Headings F1C FIT To reduce serpentine motion of a flow particle the blades of an axial-flow turbine or compressor are shaped so as to induce radial forces in the working fluid which at least partly compensate the radial forces resulting from the peripheral component of flow velocity. This is achieved by the stator blades 1 having leading and trailing edges 3, 4 conforming substantially, when viewed axially of the machine, to radii through axis O to thus exert no compensating radial forces on the working fluid, whereas the leading and trailing edges 11, 12 of each rotor blade 8 are substantially parallel causing the blades to induce compensating radial forces. Compensation can be increased if the leading and trailing edges of each rotor blade converge from root to tip as shown at 15, or if the edges of each stator blade converge more sharply from root to tip than the corresponding radii, as shown at 16. A further increase in compensation can be achieved if the rotor blades are wider than the stator blades in the circumferential direction.

Title: Improvements in the preparation of sisal fibres for manufacture into yarns or similar articles
IPC: D01C1/02
Filed: 1935-06-15
Abstract: Sisal or similar hard fibre of the Agave family is prepared for fine spinning by a treatment comprising softening some of the gums in the fibre by subjecting the completely decorticated fibre to the action of weak caustic alkali solution at atmospheric temperature and pressure, and thereafter removing the alkali and all or most of the softened gums.  The fibre is preferably pressed after the alkali treatment and then washed and if desired again subjected to pressure. Washing may follow the alkali treatment directly without intermediate pressure treatment.  The caustic soda solution should be from 2--6 DEG  Twaddle, treatment lasting for 20--45 minutes.  For very fine fibres, the strength of the solution or the time of immersion may be increased, e.g. a solution of 4 DEG  Twaddle may be employed for 60 minutes.  The solution may be circulated and the fibres may be conveyed in countercurrent thereto.  Washing may consist of immersion in running water for about 30 minutes and may be effected in a similar manner to the alkaline treatment.  The fibres are then dried and brushed.  The treated fibres may be subjected to the action of a mechanical softening machine, to split them into still finer fibres. The treatment makes the fibres more absorbent. Specification 383,627, [Group IX], is referred to.
