Title: Screw-threading attachment for lathes
IPC: B23G1/02
Filed: 1946-08-09
Abstract: 619,145. Attachments for screwing; die-heads. HOGFORS, H. F. B., and LARSSON, E. V. U. Aug. 9, 1946, No. 23707. Convention date, Aug. 20, 1945. [Class 83 (iii)] A screw-threading attachment for a lathe has a die or tap holder 8 rotatably and slidably mounted on a support 1 fitted to the tailstock of a lathe, an adjustable rod 6 disposed to prevent the holder from rotating while permitting the latter to move longitudinally to effect the screw-thread cutting over a length determined by the setting of the rod, and a rod 14 movable into and out of an operative position in which it secures the holder against rotation and permits retraction of the die or tap. The work is rotated by the headstock spindle and the die is brought into contact with the work by movement of the tailstock. During the cutting operation, an arm 9 attached to the holder bears against the rod 6 which extends beyond a flange 2 fixed to the support by an amount equal to the desired length of thread. This arm traverses the rod 6 and on reaching the end of the latter, stops the cut by allowing the holder to rotate. To unscrew the die, the rotation of the headstock is reversed, and the rod 14 pushed forward until its head 15 contacts a stop 16 on the rod 6. The rod 14 now arrests the arm 9 so that the work is unscrewed from the die. To ensure that the rod 14 is returned to its inoperative position, a plate 17 frictionally pivoted on the arm 9 is provided. During the cut, this plate occupies the position shown in Fig. 2, so that it overlaps the end of the rod 14 during the unscrewing operation. The holder 8 is provided with an adaptor (not shown) for tapping.

Abstract: 870,059. Digital electric calculating apparatus. OWEN, C. E. July 25, 1958 [July 27, 1957], No. 24028/57. Class 106 (1). An electronic multiplying device 1 in which successive multiplier digits cause repeated additions of the multiplicand to a result register together with appropriate denominational shifts, the shifts being counted by a counter 4, is augmented by a source 6 of three predetermined numbers and a group of gates 7 controlled by the counter, to form a sterling to pence converter. The sterling amount, ú12: 13: 11, as shown, is entered into the multiplier register; the first two digits, both ones, are multiplied by 1000 which is entered into the multiplicand register from source 6 via gates 7 under control of the counter (this results in 11000 being in the result register); the second two digits 3 and 1 are multiplied by 120 which is entered into the multiplicand register from source 6 as before (this causes the addition of 13 x 120 x 100 to the result register since the basic multiplier is designed to give a cumulative digit shift for each digit of the multiplier used giving 157100); and the remaining digits, 2 and 1, are multiplied by 24 which is entered into the multiplicand register (this causes the addition of 12 Î 24 x 10000 to the result register) giving 3047000 which is 1000 times the number of pence in ú12: 13: 11. A similar arrangement for converting from pence to sterling using a dividing device is described. Conversions from other mixed bases are possible, it is stated, by appropriately modifying the factors used.

Title: Photographic cameras
IPC: G03B17/18
Filed: 1972-05-23
Abstract: 1353449 Photographic camera indicating devices SEIKO KOKI KK 23 May 1972 [31 May 1971] 24146/72 Heading G2A A photographic camera has an indicating device, e. g. a lamp L, a light emitting diode or a liquid crystal, which operates in a steady manner, e.g. continuous light emission, when the light incident upon a photoconductor Rc is above a predetermined maximum strength, and which operates a varying manner, e. g. periodic light output, when the light incident upon the photoconductor is less than a predetermined minimum strength. In the former event over exposure is likely and in the latter camera vibration is likely. Contact slides a 1 , b 1  of changeover switches S 2  A, S 2  B are both ganged for movement with the shutter release. In the first position the contact slides contact a 3 , b 3  respectively. If light incident on Rc is such that V > V o , strong lighting condition, then transistors T 1 , T 2  and T 3  all conduct to cause steady illumination of the lamp L. If the light incident is below the predetermined maximum strength determined by resistor R 1  so that V x <V o  then the transistors are non conducting and the lamp L is not lit. Further movement of the shutter release causes the contact slides to contact a 4 , b 4 . In this condition transistors T 3 , T 4  together with resistors R 7 , R 8  and capacitors C 1 , C 2  constitute an astable multi-vibrator. If the light incident is below the predetermined minimum strength determined by resistor R 2  so that V x <V o , transistors T 1  and T 2  are cut off, but transistor T 3  conducts, base current flowing through the lamp L, slide switch S 2 B and capacitor C 1 . Thereafter the circuit of transistors T 3 , T 4  causes periodic illumination of the lamp L. If the incident illumination is above the predetermined minimum strength so that V x >V o , transistors T 1 , T 2  and T 3  continuously conduct and transistor T 4  is permanently cut off the lamp L remaining unlit. In a further embodiment, Fig. 2 (not shown) changeover switch S 2  A has a further contact so that further depression of the shutter release connects photoconductor Rc in series with a shutter timing capacitor the common point being connected to a Schmidt trigger which controls the closing action of the camera shutter.

Title: Fractionation of oils or other soluble mixtures of organic substances by selective extraction
IPC: C10G21/00
Filed: 1954-08-23
Abstract: 769,454. Liquid-liquid extraction process. GROLL, H. P. A. Aug. 23, 1954 [Aug. 24, 1953], No. 24446/54. Class 81(1) Oils and other soluble mixtures of organic substances are fractionated by liquid-liquid extraction under such conditions of temperature and pressure that the solvent power of the selected solvent is reduced by increase of temperature, the material to be fractionated being extracted selectively with a solvent whose solvent power has been adjusted by control of temperature and pressure and the extracted part of the oil being precipitated from the solvent by increasing the temperature of the extract, the process being characterized by increasing the hydraulic pressure of the extract before carrying out its precipitation by increase of temperature. The process is applicable to the fractionation of crude oil residues, tar oils, synthetic hydrocarbons, hydrogenation products,. glycerides, tall oil, mixtures of fatty acids and resinous acids and mixtures such as boiled linseed oil, tandoils, voltolized oil and liquid alkds. Specified solvents include ethane, propane, butane, petroleum ether and hydrocarbon mixtures, dichloromethane, dichlorodiffuoro-methane and carbon dioxide. As shown oil is pumped from tank 1 via heater 3 into the middle of column 4 operated at a temperature T1 such that the greater part is extracted leaving a heavy residue. This residue Fl is withdrawn through valve 5. Solvent passes through valve 6 and rises up the column, the extract leaving through line 7. It is pumped to a heater 9 and separator 10, the required increase in pressure being by throttling valve 23 while running pump 8 at a constant rate, or by adjusting the rate of pumping while keeping the valve position constant. Precipitation takes place in separator 10, part of the precipitate being returned to column 4 through cooler 11. The other part passes through line 13 to cooler 15 where its temperature is adjusted to the operating temperature T2 of column 16. It is then fractionated in column 16 into two parts, a bottom fraction F2 being withdrawn and top fraction F3 separated from the extract. The solvent from separator 10a is returned via cooler 21a and valve 6 to column 4. Solvent for starting the process is taken from tank 17 via pump 18, line 19 and heater 20 (which heats it to the temperature T2 of column 16) and then to column 16. The oil for column 4 may be pre-diluted with solvent before it is heated in heater 3. Solvent withdrawn with th separated fractions may be recovered and returned to the process. In this process, T1<T2, and the first heavy fraction F1 is not further, separated. The method of operation is also described in which the first heavy fraction is further separated, the temperature of column 4 in this case being greater than that of column 16.
