Abstract: 569,286. Reservoir pens. MENTMORE MANUFACTURING CO., Ltd., ANDREWS, A. E., and JOHNSON, W. F. Nov. 16, 1943, No. 19137. [Class 146 (iii)] In a reservoir pen of the kind in which the writing point 9 is hollow, a narrow lengthwise slot or slots 12 are provided in the wall of the point section which ends in a rounded writing tip 11, and an ink regulator 13 mounted within the section extends to the forward end of the ink reservoir, e.g. a sac 2. Preferably, the tip 11 has a continuous surface, the slot or slots 12 extending partly, but not completely, into the tip 11 which is of iridium, stainless steel or other hard-wearing non-corrodible material. The section 9 has a screwed tubular part 10 engaging the front part 3 of the pen, the part 10 being formed with a depression to engage and hold the regulator member 13. Two series of circumferential grooves 16<1>, 16<2> are formed in the member 13, the outer surface of the grooves 16<2> being conical and situated close to the wall of the section 9 and as near to the tip 11 as practicable. An ink-supply groove 17 extends longitudinally of the member 13 from the reservoir to adjacent the tip 11, and diametrically opposite thereto is a second and shallower but wider air vent groove 18 extending to and communicating with an air space 20 in the section 9, which is provided with air holes 21. In one modification, the section 9 is not stepped to form the screwed part 10, but is held frictionally and abuts at its inner end against a shoulder on the member 3. In a further form, the conical part of the point section 9 is secured by welding to a tubular part which extends into the part 3. Where the point section is screwed into the pen proper, the threads may consist of a series of discontinuous raised parts on the section.

Abstract: 1473389 Pipe coupling SOC D'EXPLOITATION DES BREVETS OCLAU 1 May 1974 [9 May 1973 8 June 1973] 19161/74 Heading F2G A high pressure pipe coupling comprises a rigid nut 3; a rigid body 1 having at one end an external screw threaded portion 2 to receive nut 3, the body and nut having internal tapering surfaces 4, 5 respectively and, in contact with these surfaces, a bi-frusto-conical, ductile metal, bite ring 6 having two sets of ridges 8, 16 on its inner surfaces which when ring 6 is compressed by screwing nut 3 on to body 1 are forced into circular grooves formed on an end of a pipe 7, e.g. a metal pipe which is to be coupled and having between its tapering sections 14, 15 a central section 9 of larger diameter, incorporating a circumferential sealing lip 13 which presses firmly against face 12 of body 1 when ring 6 is fully compressed. When nut 3 is screwed on to body 1 to a point at which lip 13 contacts end 12 the section 14 of ring 6 having a shallow tapering slope is fully compressed against pipe 7. On tightening nut 3 further, section 15 of ring 6 having a deep more steeply tapering slope is compressed against pipe 7 until sealing lip 13 seals firmly against face 12. Central section 9 is sufficiently large to prevent either ring 6 or pipe 7 distorting when compressed. Tapered surfaces 4, 5 of nut 3 and body 1 enclose ring 6, at least 50% of the external surface area of which forms a seal with nut 3 and body 1. The pipe coupling can be used with plastics tubes in which case the plastics tubes have internal linings to prevent their walls distorting when compressed by ring 6. In other embodiments sealing lip 13 may have a plain or rounded edge or may have a galley behind its edge to make it flexible.

Patent GB-381232-A (GB)
Title: Improvements in or relating to two-way signalling systems comprising electrically long transmission lines
IPC: H04B3/20
Filed: 1931-07-03
Abstract: 381,232. Two - way transmission. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Bjornson, B. G. ; 57, Horatio Street, New York, U.S.A.) July 3,1931, No. 19268. Convention date, July 9, 1930. [Class 40 (iv).] In a two-way submarine cable system in which a speaker in one direction gets complete control of the system so that speech in the other direction can only normally take place after a pause in the first speech equal to at least the transmission time over the cable (T), the control circuits are so modified after a predetermined time that the distant listener is able to break in and obtain complete control during a slight pause which may only be that normally occurring between words. In the system shown, when speech arrives over land line TL, relays 7, 8 transmit a courier control pulse over the cable TC, network 1 delaying the speech for a short time (t) sufficient for the control operations to be completed. At the distant station the courier pulse passing through filter 23 operates relays 27, 28, 29 for conditioning the transmitting and receiving branches, relay 30 for disconnecting relay 16, and relay 26 for connecting up speech filter 24 whereby the speech takes over the control initiated by the courier. At about the same instant at the transmitting station, part of the courier pulse which has been delayed for time T-t in network 14 passes into circuit 13 operating relay 16 to prevent any change of condition by received speech. After a further period T produced by network 18 control device 19 operates energizing relay 20 which disconnects circuit 13 so that the control of relay 16 now takes place over its left-hand winding by speech passing through delay circuits 14, 18. At a slight pause in the received speech, during the period between the release of relays 30, 31, the distant listener can break in, operating relay 16 immediately over its right-hand winding and sending a courier pulse back to the transmitting end at which the arrival of the courier will synchronize with the release of relay 16 so that both stations are now conditioned for speech in the opposite direction. Specification 338,971, [Class 40 (iv), Telephones &c.], is referred to.
