Title: Method and apparatus for pile-driving
IPC: E02D7/12
Filed: 1959-04-27
Abstract: 852,976. Internal combustion pile drivers. DORNFELD, R., and DORNFELD, E., [trading as DELMAG-MASCHINENFABRIC R. DORNFELD]. April 27, 1959 [April 26, 1958], No. 14216/59. Class 68(2). A diesel pile driver which comprises a piston 4 connected to the pile head 6 by a piston rod 41 and surrounded by a cylinder 1 which is free to move vertically is characterized in that the pile is driven solely by the force on the piston due to the pressure of the combustion gases, and in that there is no impact between the cylinder and the pile since the kinetic energy of the falling cylinder is absorbed by gases trapped in the upper part of the cylinder. The ports 11 are closed by the piston as the cylinder descends after a power stroke and gas in the cylinder is compressed and heated to a temperature sufficient to ignite fuel oil injected by a pump 8 through a nozzle 9. The quotient of length of stroke divided by piston diameter is between 0À7 and 0À2 and preferably between 0À5 and 0À3.

Title: Improvements in or relating to the treatment of yarn, or the like in hanks with liquid
IPC: D06B3/08
Filed: 1922-05-19
Abstract: 180,341. Schlumpf, J. May 20, 1921, [Convention date]. Hank type.-Hanks H of yarn &c. to be treated with bleaching, washing, dyeing, or other liquids are suspended from rollers 18 carried by a rotating carrier and mounted above a series of troughs 2, 3: the rollers 18 are alternately depressed to dip the hanks into the liquid in the troughs and raised while the hanks are being transferred from trough to trough, and when in their depressed position the rollers 18 are brought into contact with suitably-driven squeezing rollers 17. As shown, the rollers 17 are driven by bevel gearing from a vertical shaft 11. As the carrier 7 rotates and a roller 18 clears the edge of a trough, that roller is moved down, against the action of a counterweight 40 and of a spring 33 by reason of a roller 22 on a lever 20 rising on a stepped track 23. The corresponding hank is thus immersed in the liquid in the trough, and the roller 18 becomes pressed against and rotated by the roller 17, so that the hank passes between these rollers and liquid is expressed from it. When the roller 22 descends, the roller 18 is raised again by the springs 33, &c. If desired, the rollers 18 may be positively driven by the central shaft. After passing round the whole apparatus, the hanks are removed from the rollers 18.

Patent GB-1540502-A (GB)
Title: Electronic timepiece
IPC: G04C9/08
Filed: 1977-04-06
Abstract: In an analogue electronic timepiece comprising a minute hand mounted on a cannon pinion, an hour hand mounted on an hour wheel, a motor driven by pulses produced by an electronic circuit and a gear train connecting the motor pinion with the cannon pinion and hour wheel, means for setting the minute hand and hour hand to amend the time displayed by the timepiece comprises a setting wheel which is rotatable by a crown wheel in one direction for moving the hands clockwise and in the opposite direction for moving the hands counterclockwise. The setting wheel is coupled to the gear train by a friction pinion at a point in the train which is approximately midway between the motor pinion and the cannon pinion and hour wheel so that the blacklash generated in moving the hands clockwise in a setting operation is approximately equal to the backlash generated in moving the hands counterclockwise. The electronic circuit includes means for generating pulses at the conclusion of a setting operation so as to compensate for the blacklash in the gear train. Since the backlash is approximately the same regardless of the direction the hands are moved in the setting operation substantially complete compensation for the backlash can be attained regardless of the direction in which the hands are moved.

IPC: A21D2/14
Filed: 1929-05-10
Abstract: .311,389. Wiig, E. O. May 10, 1928, [Convention date]. Porous or spongy indiarubber. - A ketone carboxylic acid, such as acetone dicarboxylic acid, is used as a leavening agent in baking and also in the production of a cellular structure such as porous or sponge rubber. When used in cooking the acid is preferably mixed with a diluent such as flour, corn starch or rice starch, preferably dried by the action of heat and vacuum, and under the cooking heat the acid breaks down into carbon dioxide and acetone in vapour state. In order to effect the liberation of a small amount of gas before heat is applied alkali in the form of sodium bicarbonate, acid sodium phosphates or ammonium carbonates, is added to the batter or other mixture or incorporated in the acid-diluent mixture. Salts of sodium, potassium, lithium, magnesium, &c. may also be added. In the neighbourhood of 133‹ F., the boiling point of acetone, there can be created a sharp increase of gas formation; the temperature at which this occurs can be varied by regulating the pressure, or a different ketone may be used. When it is desired that the leavening gas shall be evolved at a higher temperature, as in the vulcanization of rubber, a more stable dicarboxylic acid, for example, 0 = C = (CH2-CH2-COOH)2, may be used.

Abstract: 1,060,478. Transistor logic circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 8, 1965 [April 11, 1964], No. 14935/65. Heading H3T. In an inverter circuit having an output circuit consisting of two transistors 10, 12 of opposite conductivity type each controlled by a transistor 9, 11 of opposite type connected in common base mode, input signals are applied via resistors 5, 6, 7 to the emitters of the control transistors so as to cause the output transistors 10, 12 to conduct alternately, the output from 4 being the inverse of the input at 8. If the majority of input signals is positive, then transistors 11 and 12 conduct to connect a negative potential (-V) to the output 4. Similarly when a majority of negative input signals is applied, transistors 9 and 10 conduct to give a positive output (+V). Charge stored in the first " on " output transistor 12 tends to maintain it on but because of the low conduction path provided by transistor 10, resistor 15 and capacitor 16, transistor 12 switches off and the effect of charge storage is thereby reduced. Transmission lines, e.g. coaxial cable 13, may be connected in parallel to the output 4 so as to feed further inverter circuits as shown.
