Patent GB-2152428-A (GB)
Title: Method of moulding a canister
Inventor: SCHIEMANN DR WOLFRAM
IPC: B65D1/00
Filed: 1985-01-04
Abstract: The method resides in shaping a pot-shaped blank 11 from nylon by injection moulding and onto the blank 11 is moulded a likewise pot-shaped outer layer 14 of polyethylene and in that the coated blank is finish-shaped to canister form by a blow moulding process. The nylon acts as a barrier layer which substantially prevents permeation for example of aromatic substances while the outer polyethylene layer 14 can be easily mixed for instance with carbon black in order to prevent electrostatic charge. The method is particularly suitable for manufacturing canisters to hold lead-free petrol, to which instead of lead other additives such as, for example, aromatic substances are added. <IMAGE>

Title: Cleaning of filter elements
Inventor: DOYLE JOHN PATRICK
IPC: B01D41/04
Filed: 1985-05-09
Abstract: An annular filter element 3 is cleaned by spinning about its longitudinal axis so as to dislodge debris centrifugally, and the debris is sucked out of chamber 6 by a fan 12, inducing outward flow of air through the filter element wall. The air enters the element via hollow shaft 5 from the atmosphere, and air may also be injected under positive pressure into the filter element. The filter element is made of paper and used in an internal combustion engine air intake, the cleaning being done in a separate apparatus as shown. <IMAGE>

Title: Conveyor apparatus for tobacco packers
Inventor: FISHBURNE FRANCIS BEATTY
IPC: G01G11/08
Filed: 1985-06-18
Abstract: A first conveyor (1) carries tobacco from a redryer and deposits it onto a reversible second conveyor (2); the second conveyor is operated to feed the tobacco onto the input end of a variable- speed third conveyor (6) arranged to weigh the tobacco as the tobacco is deposited thereon; the third conveyor is operated at a slow rate until a predetermined weight of tobacco has been deposited thereon and then is shifted to a fast rate and the second conveyor is reversed to commence operation as holding conveyor; the third conveyor discharges onto a fourth conveyor (11) and upon completion discharge of the weighed quantity of tobacco the second conveyor is again reversed and begins again to feed its held tobacco as well as incoming tobacco from the first conveyor onto the now empty third conveyor, the third conveyor being returned to its slow rate simultaneously with reversal of the second conveyor; the above steps are then repeated for as many cycles as are required. <IMAGE>

Title: Synthetic press role for paper machine
Inventor: MIIHKINEN VEIJO
IPC: D21F1/00
Filed: 1986-01-06
Abstract: In a synthetic press roll to be used in a paper machine the surface layer of the cylinder mantle of the press roll is composed of a mixture of a metal powder and a powder of an inorganic material. The metal component may be copper, bronze, stainless steel, nickel, chromium, and/or a titanium alloy, and the inorganic powder consists of quartz, feldspar, Al2O3, ZrO2, TiO2, TiC, SiC, MgO, Si3N4, Cr2O3, WC, Nbc, VC, Cr7C3, or of a corresponding ceramic material or of mixtures of same. The roll face is produced by thermal spraying, casting, by winding a sintered and/or rolled band around the cylinder, or by using a flexible mat in which the desired mix is bound by means of PTFE and in which the pre-coating is fixed by melting by means of induction or laser heating. The press roll provides means by which the detaching of the paper web from the roll face is controlled and the resistance of the roll to variations in temperature and to mechanical strains is improved.

Title: Lightweight aggregates resistant to water absorption and preparation thereof
Inventor: SAWAIDE MINORU
IPC: C04B14/02
Filed: 1986-11-03
Abstract: In a lightweight concrete aggregate which is inexpensive and excellent in resistance to freezing and thawing and resistance to water absorption, a gel is filled into at least the open pores in the surface layer of a lightweight porous aggregate. One preparation process is to inject a raw material for gel formation into the open pores in the surface layer of a lightweight porous aggregate, and allow the material to gel in these pores. Another process is to submerge a heated lightweight porous aggregate in a gel raw material solution as to fill solution into the open pores in the surface through suction by the reduced pressure effect caused by cooling of the aggregate, and converting the solution in the open pores to a gel. The gel raw material can be inorganic (e.g. a silicate), organic, (e.g. agar agar), or various oils.

Inventor: LATTA JOHN ROBERT
IPC: F04D13/06
Filed: 1987-09-16
Abstract: A pumping unit (5) floats on a body of liquid (4) and comprises a float (11), a chamber (10) whose lower end is closed by a filter (8), a multi-stage centrifugal pump (14) for propelling liquid from the chamber (10) to a delivery duct (18); and a motor (13) for driving the pump.

Title: Detecting communication path errors
Inventor: WAITE LEE
IPC: H04L1/20
Filed: 1989-10-17
Abstract: In order to detect errors in a communication path, the level of an input digital signal (INPUT) is sampled several times per bit, for instance by an up/down counter (1) (Fig. 1 not shown) or a SIPO shift register (20) and summer (21). The number of samples per bit having the same value is compared in a comparator (2) with upper and lower limits and, it the number is between these limits, an error signal (FAULT) is given.

Title: Sealing apparatus for electron gun of cathode ray tube
Inventor: PARK MU-BU
IPC: H01J9/26
Filed: 1991-03-06
Abstract: A sealing apparatus for welding an electron gun mount assembly to cathode ray tubes of different sizes includes frames (13) on a rotating index table (11). Support rods (12) support the electron gun mount assemblies (2); and heating means with nozzles (15, 15, 16 and 16) eject a flame to weld the neck portions (19) of the cathode ray tubes (1). The flames are adjusted according to the size of the cathode ray tube (1) which is detected by a detecting means near the index table (11). Fuel and oxygen supply lines having main lines and auxiliary lines are connected to the nozzles (15, 15, 16 and 16) and the flow of fuel and oxygen is controlled by a control means in response to the detecting means. In the figure 4 embodiment (not shown) there are 4 pairs of nozzles and each opposed pair of nozzles ejects a flame for a particular sized cathode ray tube when that sized tube is detected while the other opposed pair ejects a pilot flame. Thus this apparatus permits the sealing work to be performed according to the size of the cathode ray tubes, and the fuel consumption and the inferiority rate to be lowered. <IMAGE>

Title: Starting-up a controlled freezing zone process and purifying a product stream
Inventor: HAUT RICHARD C
IPC: F25J3/02
Filed: 1991-08-29
Abstract: For start-up, transformation from start-up to normal operation and normal separation of carbon dioxide and other acid gases from methane using a distillation column (100) with a controlled freezing zone (110), normally, the feedstream is treated in at least one distillation zone (106), a controlled freezing zone (110), and another acid gas stripping apparatus (116). The freezing zone (100) produces a carbon dioxide slush, which is melted and fed into a distillation section (106), and a methane-enriched stream which is fed to a separate stripping unit (116). Start-up is accomplished by refluxing the product stream from the separate stripping unit (116) to the distillation column (100). Transformation is accomplished by re-routing the methane-enriched stream produced by the freezing zone (110) directly to a separator (120) in which the stream is separated into a liquid component for refluxing to the column (100) and a vapor component to be fed to the separate stripping unit (116). <IMAGE>
