IPC: B65H23/195
Filed: 1963-07-03
Abstract: 1,046,803. Feeding webs. TIMSONS (HOLDINGS) Ltd. Aug. 14, 1964 [July 3, 1963], No. 26298/63. Heading B6B. A brake band 28, Fig. 4 (not shown), acting on a web-roll spindle is controlled by a pneumatic system, which includes a dancer roller assembly, Fig. 1, pivoted to a shaft 3 and biased against the tension in the web by a pneumatic device 6 such as a diaphragm 5. The pressure at the diaphragm 5, governed by a valve 10, is the datum pressure equivalent to the required tension in the web and is indicated on the pressure gauge 11. An air responsive device, such as the air cylinder 12 forms part of the web-roll braking mechanism. An air receiver 14, which could in fact be just the pipe lines of the pneumatic controller, is connected to the air cylinder 12 and control valves 18 and 19. These valves control the flow of air into and out of the reservoir 14 respectively and are operated respectively by cams 20 and 21 fixed to the shaft 3. A further valve 23 operated by a cam 22 may be provided to allow a fast release of air from the receiver 14 when desired, such as the case when intermittent feed is required and a quick release of brake is necessary. In a modification, Fig. 2 (not shown), the valve 23 may take the form of a valve 23<SP>1</SP> in parallel with valve 18 which opens before the valve 18<SP>1</SP> and allows air to flow into the receiver 14<SP>1</SP> slower than the valve 18. To increase the response time of the system an additional air receiver 25 may be switched in at will by a valve 24. The air pressure responsive device 12 may be used to control a re-wind drive such as that which includes an electric rewind motor with torque varying switches or movable brush gear.

Title: Door operating means
IPC: E05B65/22
Filed: 1936-09-28
Abstract: 472,201. Door-operating appliances; fastenings. SCRAGG, G. H. Sept. 28, 1936, No. 26305. Convention date, Oct. 5, 1935. [Classes 44 and 65 (i)] A fastening for doors, particularly of vehicles, including a sliding latch bolt, is provided also with sliding means for forcing the door closed, this means and the latch bolt having a common operating means, which may also operate sliding means for forcing the door open. The closing means may serve to lock the door, and may be arranged to be set for release either from the outside only or from the inside only. The bevelled latch bolt 39, which is pressed outwards by a spring 40 and which may engage a striking plate in the form of a rack to prevent swinging of the door when it is not quite closed, has a lug 42 at its inner end for engagement by the end of the closing bolt 38, which has an opposite bevel to that of the latch bolt 39 and engages a suitable striking plate on the door frame. The closing bolt 38 is operated by an arm 34 on a spindle 33, this arm having a forked end engaging a pin 37 on the closing bolt 38. When the bolt 38 is retracted, it withdraws the latch bolt 39 by means of the lug 42, but the latch bolt is not affected until after the bolt 38 is moved clear of its striking plate so that the latch may still be operative when the bolt 38 is inoperative ; when the door is nearly closed, the bolt 38 is projected to complete its closing by a wedging action, and this bolt may be held in its projected position, to lock the door, by the slightly recessed end of one limb 35 of the arm 34 passing under the pin 37 as shown. The opening bolt 46, formed with a bevel similar to that of the latch bolt 39 and engaging a suitable wedging surface on the door post, is operated by a forked tail 44 of the arm 34 engaging a a pin 45 on the bolt 46, lost motion being allowed in this connection to allow the latch bolt 39 to be withdrawn without affecting the bolt 46. The spindle 33 may be operable from either side of the door, but in the form shown it is connected to the outside door handle only, the inside door handle actuating a separate spindle 48 carrying a double arm 50. In the position shown, the closing (and locking) bolt 38 can only be operated from the outside of the door, since operation of the arm 50 would only bring a lug 54 thereon against the lower end of arm 34. In a slightly different position, with only the inner corner of the limb 35 of arm 34 engaging the pin 37, a lug 52 on the arm 50 can be made to engage a notch 53 in the arm 34 to prevent unlocking of the door from the outside ; from this position, the arm 50 can move the arm 34 to operate the bolts as required, since the lug 42 will now engage the side of the arm 34. A coiled spring on the spindle 48 presses the arm 50 in a counterclockwise direction.

Filed: 1970-06-02
Abstract: 1,242,999. Colour cathode-ray display tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 2 June, 1970 [5 June, 1969], No. 26566/70. Heading H1D. A method of manufacturing a c.r.t. luminescent screen wherein the screen includes discrete luminescent areas of differently coloured emissions (e.g. red, green, blue) separated by particles of a light-absorbing substance comprises depositing the light absorbing substance electrophotographically. For the same contrast, the window glass tinting can be reduced or omitted. In fabrication, a conductive layer is provided on the support and superposed by a photoconductive layer charged by a corona discharge. The areas corresponding to luminescent areas are discharged by exposure and charged light absorbing particles adhered to the remaining areas. The luminescent areas may be similarly applied electrophotographically, using oppositely charged luminescent particles or alternatively, the conductive and p.c. layers removed by firing, the light absorbing material adhered by adhesive, and the luminescent surfaces provided by a photosensitive lacquer. In examples, the conductive layer of polyvinyl alcohol with choline chloride additions is dried, a polyvinyl carbazole photoconductive layer applied and charged negatively by a corona discharge, the layer exposed three times through a shadow mask, and a liquid containing positively charged particles of a light absorbing substance, e.g. MnO 2 , is applied adhering to the unexposed areas, the liquid decanted off and the screen dried. The p.c. layer is then charged positively, exposed, and positively charged luminescent material applied to the exposed areas.

Abstract: 702,799. Electric furnace. AKTIEBOLAGET IGGESUNDS BRUK. Nov. 16, 1951, No. 26941/51. Class 39 (3) A radiation melting furnace has a closed chamber with a charging opening 6 adjacent an end wall 5, the space below the opening along said end wall forming a charge zone, the remainder of the furnace forming a radiation zone, and several electric resistance heating elements 3 extend horizontally and transversely in the radiation zone, the roof 4 being inclined upwardly towards the opening 6 so as to increase reflected radiation on the charge. The side walls also diverge towards the charge zone to increase heat reflection thereto. The elements 3 preferably of carbon or graphite, extend through the side walls and are of different lengths, being connected in pairs in series so as to make the total length of each pair equal. The bottom wall slopes down towards the charge zone and has at the other end a discharge opening 7 with an external lid. Thus molten material collecting at the base of the charge zone is discharged on tilting the furnace, which is tilted the other way for charging. At least one of the elements 3 is placed above the discharge opening to radiate heat thereon. The radiation area F of the heating elements 3 and the current supplied E are such that the radiation does not melt the roof, being regulated according to the formula E=k.F.(T/100)<SP>2</SP>, where k is a constant and T is the absolute temperature of the elements 3. The furnace is operated in a protective atmosphere, e.g. of carbon monoxide to lessen oxidation of the elements 3 and the formation of oxide slags, e.g. when scrap iron or sponge iron is being melted. The gas in the furnace may be at more than atmospheric pressure. The furnace has a door 8 for cleaning, with observation holes 9.
