IPC: D06F49/00
Filed: 1926-12-01
Abstract: 269,096. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Dec. 1, 1926. Casings; driving.-A centrifugal extractor has a sliding door interlocked with the controlling lever of the driving means ; a detent, movable to a position in which it obstructs the movement of the controlling lever from the " off " and " on " position, is held in that position by maintaining means which are released by a member moving with the door to the closed position. The basket 9 is suspended on a swivel mechanism 4 and is driven by means of a belt 11 on the pulley 10. A brake shoe is arranged to engage the face of the pulley 10 when actuated by the hand-wheel 26. The belt is driven by a pulley 12 on a shaft which also carries fast and loose pulleys 16, 17 Fig. 7, driven by a continuously running belt under the control of belt shifting mechanism operated by the lever 25. The sliding door 29 is connected by chains 36 to weights which tend to keep it in its upper position to expose the basket. A latch 53 engages the arm 33 upon the door and is shown in Fig. 1 in its locking position to keep the door closed; the latch can be released when the conditions are right by the engagement of the lever 25 with the tail piece of the latch. A member 37, Fig. 1, 3, secured to the spindle, has radial arms 37<a> with downwardly extending ends arranged above arcuate cup-shaped depressions in the arms of a member 38 splined upon the hub of the member 37. Balls are placed in these depressions and upon rotation of the machine they are thrown outwards to the position shown in Fig. 9 thereby forming a lock to prevent axial movement of the member 38. Engaging the under surface of the member 38 is a pair of shoes on a yoke 43, Fig. 7. secured to a rock shaft carrying an arm 47 the end of which engages a spherical head 48 on an arm 49 keved to the shaft 50 which actuates the finger 52 to engage the latch 53. Push buttoms 61, 64 are arranged in conjunction with a bar 60 so that one or the other is in the path of the lever 25. To start the machine the door 29 is lowered and is latched by the action of the finger 52 operated by the weight of the member 38 and its associated parts, upon the latch 53. The lowering of the door allows the lever arm 57<a> to be moved by its spring so that the button 61 can be depressed and the lever 25 can be moved to operate the belt shifting mechanism. To stop the machine, the control lever is moved until it is stopped by the button 64; this movement operates the belt shifting mechanism but does not release the latch 53. The brake is next applied and the basket is brought to rest. The button 64 is then depressed and the lever 25 moved to its extreme left position where it releases the latch 53 from the door 29 which thereupon rises. Upon release of the: lever 25 it moves to the position shown in Fig. 5 being moved thereto by the tail of the latch as it is operated by the finger 52.

Title: Improvements in or relating to means for detecting and localizing oil leakages in oil-filled electric cables
IPC: G01M3/00
Filed: 1955-10-27
Abstract: 776,519. Detecting and localising leaks in oil filled cables. PIRELLI SOC. PER AZIONI. Oct. 27, 1955 [Jan. 24, 1955], No. 30728/55. Class 99(2) For the purpose of detecting and localizing an oil leakage in the metal sheath of a single-core or multi-core oil-filled electric cable the cable has combined therewith an oil filled conduit of approximately the same length and extending longitudinally in substantially the same direction as the cable and in proximity thereto, two manometer tubes connected respectively with one end of the cable sheath and one end of the conduit, which ends are substantially coterminous and means for simultaneously freezing the oil in the cable and in the conduit at any selected point along the cable length. As shown an oil leak in an oil or liquid insulating compound filled electric cable C, is located by connecting manometer tubes Ti, T 2 , T 3 , T 4  to the ends of the cable and to the ends of an adjacent cable C 2 . The cables are frozen at an intermediate point and an oil leakage is indicated if a difference of oil level occurs in the tubes T 1  and T 2  or T, and T 4 . If the leakage is in the section A1 then the cables are frozen at an intermediate point of this section and the test repeated. The freezing is repeated in succession at the middle points 3, 4, 5, 6 of the lengths in which leakage has been noticed. Thus it is ascertained that the leakage is in the length 5-6 the size of which is so small as to render it possible to examine it throughout. The cables may be supplied with oil under pressure from the feeding tanks S 1  S 2 . The upper ends of the tubes Ti, T, may be connected to a container of compressed gas by means of a cock R11 and the tubes T 3 , T 4  be connected to a container of gas under pressure by means of a cock R12. In Fig. 2, C is the section of a line consisting of a single three core oil filled cable comprising ,an intermediate joint I. The cable incorporates a metallic tube D which contributes to the feeding of the cable with oil. The tube may be completely separated from the cable by closing the cocks R13, R14 and R15. The manometer tubes T 1  and T 4  do not possess the same diameter as the tubes T 2  and T 3  but the sections of the respective tubes are proportional to the known volumes of oil contained in the cable C and in the tube D despectively. The method of testing is similar to that described with reference to Fig. 1. Specification 369,119 is referred to.

Title: Improvements in or relating to the treatment of drying oils
Filed: 1948-11-30
Abstract: <PICT:0650159/III/1> In the treatment of a drying oil with sulphur dioxide, a dispersion of the oil and gas is passed in a continuous stream through a heated tubular reactor.  The use of a dispersion or foam of the oil and gas ensures a satisfactory contact between the gas and the oil in large-scale production of isomerized and polymerized drying oils using sulphur dioxide.  The drying oil may be heated, preferably to about the temperature of the reaction, before being mixed with the sulphur dioxide.  In a suitable plant, the oil from a storage tank A preheated in a coil B is mixed with the sulphur dioxide in a heated mixing chamber C by means of a bell stirrer D, and the foam-like mixture of oil and sulphur dioxide is then passed through the heated tubular reactor F and finally to a separator G where the gas and volatile decomposition products are removed by a suction pump.  The temperature and rate of flow of the reactants in the reaction tube may be so adjusted as to ensure that the desired degree of reaction takes place during the time of passage through the reactor.  Using a temperature of 350 DEG  C. 20 poise stand oil may be prepared in 3 to 4 minutes.  Specifications 343,099, 480,677 and 544,482 are referred to.

Title: Digital electronic timepiece
IPC: G04G9/00
Filed: 1976-07-26
Abstract: 1514857 Electronic timepiece DAINI SEIKOSHA KK 26 July 1976 [11 Aug 1975] 31086/76 Heading G3T . [Also in Division G5] In an electronic timepiece, e.g. a watch, with digital LCD display, different time unit displays are distinguished from one another by their colour, the display drive voltage and hence the colour being changed when a different time unit is selected for display. In Fig. 1, a timekeeping circuit 1 including a  crystal controlled oscillator, of divider and counters, feeds four time unit signals, e.g. corresponding to month, day date, hours, mins., to a switching circuit 5. A circuit 3 boosts the voltage received from a battery 2. A circuit 4 derives four voltage levels from the boosted voltage and supplies them to a switching circuit 6. A manually operable rotary selector switch 7 controls the switching circuits to select a time signal to be displayed and the appropriate voltage level and apply them to a driving circuit 8 to activate the display devices 9. The switching circuit (5) Fig. 4 (not shown), comprises AND gates to which segment signals from timekeeping circuit 1, are respectively applied. The gates are selectively opened by a signal from switch 7 and their outputs are applied via OR gates to drive two 7-segment digits. Switching circuit 6, Fig. 5 (not shown), comprises four transmission gates controlled by signals from switch 7 to couple a selected voltage level to the circuit output terminal. Display drive circuit. Fig. 6 shows a portion of the drive circuit 8 for one digit only. The seven segment signals are respectively applied to Ex OR gates 33 together with a 32 Hz signal from a terminal 34. The selected voltage level is received at terminal 32 and applied to the input terminals of transmission gates 36, the outputs of which are respectively connected to segment electrodes a to g, in common with the outputs of gates 37. Gates 36, 37 are controlled by the segment signals and the 32 Hz signal. The output of gates 40, 41, which are controlled by the 32 Hz signal, is applied to common display electrode X. Amplifiers 35, 39 raise respective voltages to the level of the booster circuit 3 output. In operation, when a segment signal at 17 is high and the 32 Hz signal is high, gates 36, 41 conduct simultaneously to apply voltage in one direction between selected segment electrodes a-g and X across the LC material. When the 32 Hz signal turns low, gates 37 and 40 conduct, applying the selected voltage of line 32 in the opposite direction. Thus when a segment signal is high alternating voltage at 32 Hz is applied between the segment and electrode X. The display device may comprise only two alphanumeric display units, the timepiece size thereby being minimized making it more suitable for a lady's wristwatch.
