Filed: 1936-06-17
Abstract: 460,752. Air-locks. SHEVLIN, J. T. (Skip Compagnie Akt.-Ges.) June 17, 1936, No. 16907. [Class 68 (ii)] [Also in Group XXX] In order to prevent direct communication between the outer air and air shafts having bucket-hoisting installations, the closing device for the discharge bunker of the shaft and a closing device for the shaft are so interconnected that one of them is always closed. In the construction shown in Fig. 1 the shaft 1 and hoisting frame 2 are sealed from the outer air by a lining 3. The bucket 6, on being hoisted to the discharging position shown, has lifted a cover 4<1> from the position 4 on top of the shaft, but the outlet to the outer air is closed by a door 8 in the discharge bunker 7. When the bucket has been discharged into the bunker 7 it is lowered and leaves the sealing door 4<1> in position 4 on the top of the shaft, any suitable mechanical or electric connecting means being provided between the cover 4<1> and the door 8 so that one is always closed. The bunker 7 may discharge on to a conveyer 9. In the construction shown in Fig. 4 the top of the shaft is sealed by a lock chamber 12 closed at the top but open at the bottom. The door 14 of the discharge bunker is closed when the bucket is in the shaft. As the bucket 15 enters the lockchamber a member 16 carried by the bucket and fitting in the lock chamber acts as a seal for the air shaft. The door 14 is controlled by means dependent on the position of the bucket so that only when the bucket member 16 closes the lock chamber can the door 14 be opened. In both constructions a double bucket hoist may be employed, each bucket having a separate cover 4<1> or member 16, but discharging into a common bunker.

IPC: G04G5/00
Filed: 1977-04-22
Abstract: A resettable interval timer in combination with, but functioning independently from a digital watch which provides horological information. The watch operates in two modes; the first mode displaying horological information on the display devices and the second or stopwatch mode displaying interval timing information on the display devices. In the watch mode the user can program which horological information he desires to be continuously displayed on the display devices, either hours, minutes, and seconds, or hours, minutes, and date. By depressing one of the watch push buttons the user can momentarily display month, date, and the A.M. or P.M. horological information on the display devices. A predetermined push button depression sequence can be used to reset the horological information. When a second push button is depressed a predetermined number of times within a defined time interval the watch enters the stopwatch mode. In the stopwatch mode the user can reset the interval timing counters to zero, start the interval timer, stop the interval timer, freeze the interval timing information currently on the display devices (split or lap time), return the counters to the interval timing mode, and finally return the watch to the watch mode.

Title: Process for making cellulose sponge
IPC: C08J9/00
Filed: 1962-05-03
Abstract: A process for the manufacture of cellulose sponge comprises forming a mixture of a viscose, a pore-forming substance, cellulose fibres and sodium hydroxide in an amount which together with the sodium hydroxide present in the viscose gives a total concentration by weight, based on the weight of solution, which is within one unit of the percentage concentration necessary to cause maximum swelling of the fibres in the mixture and subsequently coagulating and regenerating the mixture to form a sponge structure.  The fibre may be, for example, cotton ramie, jute or flax.  Sodium sulphate or other water-soluble salts and gas-forming substances, e.g. aluminium powder are suitable pore-forming agents.  After the regeneration the sponge is washed to remove the pore-former.

Filed: 1946-06-04
Abstract: 615,928. Mechanical relay and follow-up devices. LANDIS & GYR SOC. ANON. June 4, 1946, No. 17009. Convention date, June 26, 1945. [Class 118 (ii)] A mechanical relay for an indicating system comprises a primary indicating member, movement of which is capable of bringing either of two power-driven gear-trains into driving relation with a secondary indicating member by the engagement of parts of the two indicating members with one another in a manner incapable of disengagement by slipping. A motor-driven pinion 2 drives a gear 3 mounted idly on the spindle 9 of an instrument pointer 91. Mounted on shafts 10, 11 on the pointer 91 are two sets of pinions 4, 5, 6 and 7, 8 which are driven continuously in opposite directions by the gear 3. If the pointer 91 moves from its neutral position, either pinion 5 engages a gear 15 mounted idly on a recording arm 12 or the pinion 8 engages a similar gear 16. Thus, either a pinion 17 or a pinion 18 will commence to roll around a fixed gear 19 carrying with it the recording arm 12 and pencil 20, the move. ment of the instrument pointer 91 being thus recorded upon a moving strip 21. The swing of the pointer 91 and recording arm 12 continues until the displacing force is balanced by a helical zeroizing spring 22 when the pinion 17 or 18 ceases to be driven and the recording arm 12 remains in its present position until the instrument pointer 91 swings in the reverse direction. In a second embodiment (Fig. 3, not shown), movement of the instrument pointer releases a brake from one of two geartrains which is then driven by a motor via a differential system to cause a pinion to roll around a fixed gear in the appropriate direction, carrying with it the recorder arm.

Abstract: 596,846. Working cycles. TEXACO DEVELOPMENT CORPORATION. Oct. 18, 1943, No. 17117. Convention date, Oct. 23, 1942. [Class 7 (ii)] A method of and means for operating an internal combustion engine comprises introducing into the cylinder air without sufficient fuel to produce combustion, compressing the air therein, injecting fuel into the compressed air at a temperature and pressure ensuring that at least a portion of the fuel is instantly vaporized and forming a local area of combustible mixture adjacent the injection nozzle, igniting the mixture by a spark and establishing a flame front before sufficient fuel has been injected to cause knock and continuing the injection of the fuel in a narrow zone in advance of the flame front to form additional local areas of combustible mixture which are promptly ignited and burned. Fuel is injected tangentially into the combustion space through a nozzle 20, Fig. 2, directed along the whirling air stream produced by introducing the air tangentially through a shrouded inlet valve 14, the fuel being introduced at such a rate that the flame front 38 remains stationary or does not progress by more than 90 degrees of the swirl. The injection nozzle 60, Fig. 5, may be arranged radially and the swirling motion of the air be omitted, the fuel then forming a segment 61 of combustible mixture which forms a flame front which travels across the combustion chamber with the point of injection as a pivot, the nozzle delivering movements of fuel to the area immediately in front of the flame as it progresses across the combustion space. Alternatively, the nozzle may form two opposed segments 61, 68 of mixture which approach each other across the combustion space. In another form, the injection nozzle is central and narrow sectors replace the segments. The fuel may be heated to ensure that it vaporizes immediately and the control of the fuel be the sole control of the engine, a full charge of air or weak air-fuel mixture being drawn into the cylinder on each induction stroke. The method permits a low octane fuel to be used with a high compression ratio.
