Abstract: 1325750 Valve assembly for oil burner pump O ECKERLE 10 Dec 1970 [12 Dec 1969] 58696/70 Heading F4T A quick-acting valve and regulating valve assembly for an oil burner pump includes a first path of connection between a pressure chamber 16 and a return chamber 19 of the quick-acting valve, said path being in the form of a throttle so constructed that with increasing pressure its cross-section decreases and/or its effective length increases and comprising one or more slots or cutouts 3 which widen continuously, for example conically, in the direction of flow therethrough, formed on the outer periphery, of a piston 2 in the axial direction. In operation, the pump initially delivers air until the system is deaerated, this air flowing in turn through bore 15, pressure chamber 16, bore 17, slots 3, regulating valve return chamber 12, bore 18, return chamber 19 and return bore 20. Subsequently, oil pressure rises until quick-acting piston 21 is lifted off valve seat 27, allowing oil flow through connection 23 to a combustion nozzle and establishing a further communication between pressure chamber 16 and return chamber 19 via bores 25 and 36. The piston 2, disposed in a cylindrical valve bush 1 in pump casing 10, may be made from a bearing needle and is acted on by a compression spring 5 which is adjustable by means of a valve screw 6.

Patent GB-1276377-A (GB)
Title: Gas turbine engine with improved gas seal
IPC: F01D11/04
Filed: 1969-12-04
Abstract: 1276377 Seals GENERAL ELECTRIC CO 4 Dec 1969 [11 Dec 1968] 59267/69 Heading F2B [Also in Division F1] The invention relates to a seal device of a gas turbine engine and is described with reference to a seal device 50 associated with an end thrust balance chamber 42 of a free power turbine 14 of a gas turbine engine. The balance chamber 42 is defined by a stationary structure 39 which is formed with flanges 56, 58 to which further stationary parts 64, 60 are secured, the part 64 being a casing portion defining part of the inner boundary of the annular gas flow path at the outlet of the power turbine. The casing portion 64 carries honeycomb seal members 66 and the part 60 carries honeycomb seal members 62. A flange member 72 is secured to the power turbine rotor shaft 32 and is formed with sealribs 70 which co-operate with the stepped honeycomb seal members 66. A further flange 68 is secured to the shaft 32 and is formed with seal ribs which co-operate with the stepped honeycomb portions 62. Pressure air tapped from the compressor 20 passes through line 43 into the balance chamber 42 and tends to leak through the seals. A shield 82 is secured in spaced relation to the outside surface of the casing portion 64 by means of ribs 84 so as to define an air flow passage therebetween through which cooling air passing out of the power turbine rotor through openings 80 flows together with leakage air from the seal 66, 70. This flow of air adjacent the outer surface of the casing portion 64 maintains the latter relatively cool, whereby the rotating and stationary parts of the seal 66, 70 are maintained at substantially the same temperature and so less differential thermal expansion occurs.

Abstract: A container is provided for bulk mail, and the like, which has the form of a wheeled rack. The container is constructed to have a lower shelf and an intermediate shelf, both of which are hinged to a supporting frame, and each of which may be turned from a horizontal load supporting position to an upright position when the container is not in use to enable the container to be nested into other like containers so as to conserve space. The container also includes an intermediate frame which surrounds the intermediate shelf and which supports the intermediate shelf in its horizontal position, and which also is hinged to the supporting frame and may be turned with the intermediate shelf to an upright position. Also, the intermediate shelf may be turned up when the container is in use to provide sufficient space within the container for large or bulky packages or mail sacks, the same extending through and being restrained by the intermediate frame which remains in its horizontal position. The container also has a flexible webbing member which is removably attached to the front of the container by a restraining bar which has ends that hook over side struts of the container. When the restraining bar is in place, the webbing member may be extended upwardly and downwardly from the restraining bar across the open front of the container to enclose the upper and lower portions of the open front so as to retain the load within the container.

Title: Method and apparatus for sealing a tube of thermoplastics material by welding
IPC: B29D23/00
Filed: 1979-03-08
Abstract: A method of sealing a tube of flexible thermoplastics material by welding in which opposite sides of the tube are pressed flat between two jaws. The flattened tube thus has two opposed flat walls which have inner faces in contact, and these flat walls are connected at two opposite edges by folds caused by the flattening of the tube. The jaws are maintained a fixed distance apart, and one is rapidly reciprocated along its longitudinal direction by a vibrator, relatively to the other jaw. This causes the contacting flat walls to rub and become so heated by friction that the contacting plastics faces melt. These molten areas unite in a weld when reciprocation of the jaw is stopped and the plastics cools.

Abstract: A lubricant is applied to an intaglio printing cylinder 6 or other printing-image carrier and serves to reduce wear of the carrier and associated doctor 4. The lubricant can be formed of a suitable solid lubricant, for instance molybdenum disulfide, or of a carrier in which there is embedded the solid lubricant. The lubricant is then usually rubbed on to the cylinder surface. However, the lubricant need not be solid and can also be applied in a different manner, for instance, by rolling or spraying. The lubricant can be applied to the printing-image carrier at any site before or after inking <IMAGE>
Patent GB-2022843-A (GB)
Title: Determining Carriage Position
IPC: G01D5/347
Filed: 1979-06-06
Abstract: The position of a carriage 5 along an arm 4 is determined by an inductive sensor 7 and an optical sensor 10. The carriage carries two spaced coils 11 and 12 energised with out of phase alternating signals that induce current in a coil 17 of the inductive sensor mounted on the arm, the phase difference of the induced current varying with movement of the carriage. The optical sensor is mounted on the carriage and senses light reflected from markings along an encoded strip 40 extending along the arm. The output of the optical sensor is in digital form and gives an indication of that portion of the arm within which the carriage is located. The phase difference of the current in the sensor coil is also derived in digital form and this gives an indication of the location of the carriage within that portion of the arm. <IMAGE>
