Title: Improvements in and connected with revolution counting apparatus
IPC: G06M1/06
Filed: 1932-05-13
Abstract: 401,363. Counting-apparatus. NORTH & SONS, Ltd., Whippendell Road, and ALLEN, A. MASSEY-, 142, Queen's Avenue, both in Watford, Hertfordshire. May 13, 1932, No. 13837. [Class 106 (i).] Transfer mechanism.-In counting-apparatus with coaxial drums adapted to be frictionally driven by the driving shaft a spring operated lever is arranged between adjacent drums and has inclined detents for engaging radial notches on the higher drum to hold it against rotation, said drum being freed by the cooperation of the detent with a single cam tooth on the lower drum. The inclination of the detents enable the notches to slip past when the drums are reversely rotated. The spindle b, Fig. 1, on which the numeral drums a are frictionally mounted is operated by a gear wheel q formed with ratchet teeth cooperating with radial extensions v of a spring controlled slidable member w housed in a hollow in the spindle. The drums a are pressed into frictional driving engagement with interposed sleeves c, slidable but non-rotatable on the spindle b, by means of a spring d. Each drum is formed on one side with a single tooth k, Fig. 5, and on the opposite side with a set of ten equally spaced radial notches l, Fig. 4. Mounted in the brackets supporting the spindle b is a U-shaped member o on one limb of which is pivoted a set of detent levers n controlled by springs p. The levers n are in the form of straight blades with detent projections n<1>, n<3> for engaging the notches and single tooth on adjacent drums and with an extension n' for guidance by the peripheral portions of the drums. When the single tooth rocks a lever n the projection n<1> is withdrawn from a notch on the next higher drum and the drum is rotated frictionally to the extent of one unit. Zeroizing-mechanism.-To the end of the driving spindle b is secured a pinion r which is operated to rotate the spindle reversely to effect the return of the numeral drums a to zero position, the drums being arrested by the engagement of the detents n<3> with the single toothed disks k of the drums. The pinion r is adapted to mesh with a pinion s on a shaft t when the shaft is displaced for the zeroizing operation. During the displacement a conical portion of the shaft displaces the member w to disconnect the driving pinion q.

Title: Engine oil analysis system
IPC: G01D21/02
Filed: 1970-03-24
Abstract: 1300120 Infrared absorption analysis MOBIL OIL CORP 24 March 1970 [24 March 1969] 14130/70 Heading G1A A sample of oil from a sequence of samples is tested for its viscosity, metal content, and infrared absorption and the results are compared in a computer with evaluation criteria which may comprise limit and trend values to provide information in respect of the engine from which the sample has been taken and to provide a print out of results and probable remedial action. The samples are fed on a table and applied to the test equipment by suction and dipping and the infrared spectrometer which may make a number of absorbance tests at different wavelengths for glycol, water content, oxidation, and nitration includes a number of reference samples which may be brought mechanically and possibly by programme into the system as required. The measuring cell is shaped to provide a thin rectangular sample and its inner walls are grooved as at 44, 45, Fig.6 in order to facilitate more rapid filling and emptying and more efficient purging. The test results are introduced to the computer in digital form and the incoming signals are tested for validity before comparison. A record of the measurements may be made and in connection with infrared testing the speed of the recording medium may be varied in dependence on zones of interest. The arrangement may be controlled by a timer which itself may be programmed and the reports may be stored before print out to economize on printer time. A local computer dealing with simple comparisons may be used in conjunction with a further computer which may be connected by line. Metal content may be measured by atomic absorption, X-ray fluorescence, or neutron actuation.

Filed: 1943-08-31
Abstract: 567,950. Harvesting corn. TIMMIS, J. Aug. 31, 1943, No. 14156. [Class 6 (iii)] An attachment for a tractor, employed in harvesting corn and similar crops, has two forwardly extending deflector members, each inclined in the same direction with reference to the line of travel and each adapted, when the device is fixed in position on the front of the tractor, to deflect a width of standing corn to one side in advance of the tractor wheels, so that the wheels will run over the deflected straw and so kink it without running over the ears of corn. In the construction shown, the attachment comprises a frame member 1 which is secured by bolts 2 to the front axle a of the tractor and which is formed with a forwardly extending arm 3. A pair of arms 4, 5, arranged in V formation, is secured to the arm 3, and co-operating with these arms is an arm 8 having its rear portion 8a, considerably nearer the ground than the remaining portion. At the other end of the member a is a further arm 7, this arm and the arm 5 being respectively disposed in front of the left- and right-hand wheels of the tractor. In use, these two arms 5, 7 deflect the corn outwardly and the wheels b will thus pass over the straw and not the ears and, further, will kink the straw so that it does not rise again. Member 4 deflects the corn inwardly and the member 8 bruises or binds over the straw to prevent it from rising ; this portion of the bent-over straw is run over by the wheel of the binder.

Abstract: 1,043,326. Refrigerating. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. April 3, 1965, No. 14214/65. Heading F4H. In an absorption refrigeration system having first and second stage generators 24 and 12, respectively, the former comprises a direct fired, horizontally disposed tube-and-shell heat exchanger having fire tubes 70 and 26. Vapour generated in 24 passes via line 28 to and through tubes 30 in the second stage generator 12 while solution from 24 passes via overflow device 69, line 32, heat-exchanger 29 and line 34 to a drip device 112 positioned above tubes 30. Solution dripping over the tubes 30 is heated thereby to release refrigerant vapour which is condensed on condenser tubes 40 and the refrigerant in tubes 30 is condensed, discharges to a header chamber and then passes through an orifice 106 to a further header chamber 36. Any flashed refrigerant vapour so produced is returned to the shell 38 containing generator 12 and the condenser for condensation on tubes 40 and the liquid refrigerant from chamber 36 passes through line 119 to join refrigerant from condenser trough 42, the combined stream being passed through a restriction (not shown), a drum 44 and line 136 to a distribution device 140, 144 positioned above the evaporator. Absorbentrich solution from shell 38 passes via line 56, heat-exchanger 58 and line 60 to a distribution device 160, 162 positioned above the absorber tubes 54. Non-evaporated refrigerant from the evaporator is collected in trough 50 and recirculated to drum 44 by pump 53 while refrigerant-rich solution is withdrawn from the bottom of the shell 120 containing the evaporator and absorber by a pump 166. Part of said solution is returned to the first stage generator via line 63, heat exchangers 58 and 29, line 64, chamber 65 and line 20 and the remainder is recirculated to the absorber through line 168 under the control of a valve 170 which is modulated in accordance with the outlet temperature of the medium to be cooled. This temperature may simultaneously be used to determine the rate of fuel supply to the burner of generator 24. Chamber 65 is connected to the upper part of generator shell 24 through line 67 to equalize the pressures therein and to ensure that on shut-down of the machine solution remains in generator 24 by virtue of the liquid trap formed by line 20. A spray eliminator 80 having perforated inclined walls 84 is provided at the inlet to line 28 and a further eliminator 94 (Fig. 2, not shown) is provided in the inlet header for tubes 30.

Abstract: 145,246. Ciabotti, C. June 10,. 1919. Leaf-turners.-In a leaf-turner for books, music, &c. two rotary arms are employed, one of which moves the leaf through a portion of the distance it has to travel, afterwards, the other carries into action to complete the movement. The arms are pivoted at b above and below the pulley c operated in one direction by the wire e leading to a handle or pedal and in the other by the spring f. The lower arm k carries a rubber .bulb m, which in the normal position, shown in Fig. 1, is compressed by levers n, n<1> forced apart by the tapering block o. When the pulley c is rotated by the wire e, the pin g moves the arm k forward, the levers n, n<1> travel to the point of the block o and the bulb m expands, sucking the leaf to be turned against the funnel mouth m' As the arm k comes forward, the leaf is pressed against the finger q pivoted to the upper arm p, bending down the finger which rises again behind it under the action of a counterweight r. After further motion of the arm k and pulley c, the pin h trips a spring catch engaging the hub of the upper arm p, which is then thrown by the spring s, so that the leaf is moved to its position on the left by the finger q. On releasing the wire e, the spring f returns the parts to the starting position ready to act on the next leaf.

Title: Improvements relating to fire-extinguishing sprinkler systems
IPC: A62C35/64
Filed: 1929-05-11
Abstract: 327,049. Burgess, A. F., (Automatic Sprinkler Co. of America). May 11, 1929. Sprinklers, automatic.- A sprinkler system wherein air under pressure is maintained in the distributing pipes and in a control tubing, is provided with an air injector for maintaining automatically the air pressure in the pipes. A derangement alarm is provided. As shown, the system eomprises a main pipe 6, dry distributing pipes 8, 10 with fusible heads 16<1>, and a main valve 12 controlled by a tubing system 16 acting in known manner through a control chamber 14. The device 18 for maintaining the air pressure is connected to the pipe 8 by tubes 19, 19<a>, and to the chamber 14 by a tube 19<b>. The device comprises a pressure chamber within which is mounted an air injector 22 supplied with water from the main 6 by a pipe 20 under control of a valve 24. Air is drawn in through a tube 26 with a one-way valve 28. The valve 24 is operated by a lever 42, a tubular rod 48, and an annular float 44 arranged within the inner of two concentric chambers 52, 64 which communicate at their lower ends. The outer chamber 64 has an overflow to atmosphere at 66. In normal condition, the water stands at the level b in the inner chamber and at the overflow level a in the outer chamber. Should the air pressure in the piping 8 or 16 fall, owing, for example, to a leak, the float 44 rises and opens the valve 24. When the injector has re-established the air pressure, the float 44 sinks, and closes the valve 24. A second float 54 arranged within the float 44 carries a rod 56 adapted, if the float rises sufficiently, to engage and operate a lever @6 controlling a valve 34 in a pipe 38 connecting the pipe 20 to a watermotor alarm 40. Should the injector fail to reestablish the air pressure, or should it fail to operate at all, the float 54 rises sufficiently to open the valve 34, and an alarm is given. A pipe 41 leads from the discharge side of the main valve 12 to the water-motor, so that an alarm is given when the main valve opens.

Abstract: 774,299. Cleaning tubes. SMITH, W. H. May 20, 1955 [May 20, 1954], No. 14874/54. Class 99(2) Spiral guide elements 2 loosely mounted in vertical tubes 1 for the passage of combustion gases in a boiler are raised and lowered with a jolting movement to clean the tubes. The elements 2 are provided with mushroom shaped heads 5 engaged on the underside by arms 8 of bell-crank levers 9 actuated by pins 11 on a sliding member 10 reciprocated by a cam 18 engaging a pin 17 thereon. The cam 18 is rotated by an electric motor controlled by a timing mechanism which causes the motor to operate for a predetermined period after the fan supplying forced air to the boiler has run for a predetermined time. The cam 18 moves the member 10 to the right and then releases it to allow the elements 2 to fall quickly under their own weight. The arms 8 contact the heads 5 off-centre and produce slight rotation of the elements 2 when they are lifted. The member 10 may be reciprocated manually by a lever 23 engaging a projection 14 and the motor may also drive a declinkering mechanism. The main flue passage may be connected to the ash pit by a valve on to which the ash from the elemerits 2 falls, the valve being opened at intervals by means controlled by the time for which the air fan has been in operation. In-a modification the member 10 is replaced by a chain carrying a projecting pin which operates each lever 9 in succession. In Fig. 6 the spiral elements 2 of two rows of tubes 1 are hung from carriers 41 on a shaft 42 which is adapted to be oscillated by a detachable handle 46 or by power operated means. A cross-bar 47 hits against stops 48 to produce jolting of the elements 2.
