Title: Prelagged reinforced plastic ducting
Inventor: EVANS REGINALD WARNFORD
Filed: 1962-10-20
Abstract: 1,069,253. Laminates. GOOLE PLASTIC HOMES Ltd. Jan. 20, 1964 [Oct. 20, 1962], No. 39775/62. Heading B5N. [Also in Division F2] A process for the production of ducting comprises covering an inflatable rubber former or a former made of a number of pieces of metal with a thin layer of synthetic film-forming material, and building up the wall of the ducting by applying in succession a layer composed of a synthetic resin material, such as an epoxy resin, and reinforcing material such as glass fibres which may also include a particulate material or aggregate such as broken sea shells and applying a layer of heat-insulating material bonded to the reinforced resin. The filmforming material may be polythene or regenerated cellulose and may be a preformed sleeve or be applied to the former in liquid form. The heat-insulating material may be asbestos or micafil held together by a moisture-proof cold water glue applied to the resin before the resin has set. Hessian may be wrapped round the reinforced layer before it has set, and around the insulating layer and a layer of resin-bonded sand applied to the second hessian layer.

Title: Method and apparatus for dividing metal sheets into strips
IPC: B23C3/28
Filed: 1968-08-23
Abstract: 1,242,754. Sawing. BROWN, BOVERI & CIE. A.G. 23 Aug., 1968 [24 Aug., 1967], No. 40509/68. Heading B5L. [Also in Division B3] A method of dividing up strips or sheets 1 of metal comprises drawing the sheet or strip from a feed drum 2, passing it through a groove forming device wherein it is guided over a supporting roller 5 and provided with grooves 7 by chip removing tools 6, which are movable transversely of the feed direction of the metal, the depth of the grooves amounting to at least half the metal thickness, and finally dividing the metal into strips by chip removal, rupturing or breaking through the residual material along the grooves. The metal strip 1 is first passed over a guide roller 3 and then around a measuring roller 4, which is provided with magnets 11 and a periphery having a high coefficient of friction. The transverse movement of the tools 6, which may be circular saws, is effected by a cam disc or plate coupled either to the roller 4 or the roller 5. Rollers 16, 17 are provided on either side of each tool 6 to maintain the strip 1 in contact with the roller 5 and the edges of the strip are pressed down by obliquely mounted rollers 18. The surface of the supporting roller 5 may be hardened or provided with a ceramic coating. The grooved strip then passes through guide rollers 8 and is wound on to a drum 9 to form a coil 10. The coil 10 is inserted in the feed drum 2 and the strip 21 passed over a roller 19, the measuring roller 4 and supporting roller 5 so that its ungrooved surface is presented to the tools 6. The movement of the tools 6 is controlled by a sensing organ 22 and the grooved strip is cut through to provide a plurality of narrower strips and wound on to a drum 20. The organ 22 comprises a U-shaped magnet, which senses the groove positions by reacting to the change of magnetic flux in the locality of the groove. The drum 20 is then placed in a transfer winding device (47) where alternate strips are respectively wound on to two drums (49), (50), Figs. 11, 12 (not shown). In an alternative embodiment the sensing organ 22 is located downstream of the tools 6 and further tools (25) complete the severance of the strip 1 into narrower strips, Fig. 3 (not shown).

Abstract: 1503880 Low pressure fuel injection apparatus ROBERT BOSCH GmbH 6 Oct 1976 [7 Oct 1975] 41510/76 Addition to 1336606 Heading F1B A fuel injection system as claimed in claim 1 of Specification 1336606 has provision for increasing the ratio of fuel to air when the engine is operating at full load. To allow valve 10 to provide additional fuel the pressure of fluid in chamber 40 is reduced by opening duct 44 thus connecting line 38 to line 43. Diaphragm 45 is pressed against the end of duct 44 by pin 48 which is acted on by spring 60, which abuts diaphragm 61. Chamber 62 is connected through passages 63 and 56 to the air intake passage 5 between measuring element 11 and throttle valve 7; chamber 58 is connected to a point downstream of throttle valve 7 by passage 64. There is a throttled leak 57 between chambers 58 and 55. As the absolute pressure in passage 64 increases the effective force of spring 60 decreases, duct 44 is opened and the restoring force in chamber 40 decreases. A second spring 46 also acts in a direction to close off duct 44 and its effect is opposed by a bi-metal spring strip 50, so that additional fuel is also supplied when the engine is cold. An electrical heater 53 begins to heat the strip when the engine is started.

An electro-photographic camera has a corona charging device 42 for an imaging member 30 within a light tight housing 14 and means to develop a latent image formed on the member by charging and exposure thereof. A movable slide 34 carrying the imaging member 32 has a focusing screen 38 viewed by opening a door 40 to focus the image of the subject by adjustment of knob 27. The corona discharge device 42 is traversed across the imaging member by lead screws 59, 60 driven by an electric motor (not shown), under the control of press button 48. An optical screen which extends the tonal response of the imaging member is removably carried by a vertically movable slide 80 which can also be moved to adjust the space between imaging member 30 and the screen. After exposure, the imaging member may be removed from the camera for development of the latent image or may be moved by actuation of slide 34 into a developer housing 16 having a container 95 for solvent liquid. The solvent liquid softens a layer containing photo-sensitive particles, such that the photo-sensitive particles that have been exposed to radiation migrate through the softened layer forming an image corresponding to the subject in the manner described in Specification 1, 152, 365. After development, slide 88 is raised to remove the developed and imaging member 32. The member 32 may consist of an aluminized "Mylar" (Registered Trade Mark) substrate having a layer of amorphous selenium evaporated on to a layer of "Piccopale" (Registered Trade Mark). Solvent vapour development as disclosed in Specification 1, 152, 365 may be used in place of liquid development.
