Title: Writing instrument
IPC: B43K24/10
Filed: 1968-12-16
Abstract: 1,217,720. Multiple retractable writing instrument. ETABS REGNAULT S.A. 16 Dec., 1968 [14 Dec., 1967], No. 59669/68. Heading B6P. In a multiple, retractable writing instrument having a single push button 5 for rotating and sliding a drum 3 housing a plurality of cartridges, only a single compression spring 11 is provided for the projecting mechanism, which spring acts against the drum 3 biasing it rearwardly. The drum 3, (Fig. 10) has a first chamber 3a for slidable receiving the rear ends of the cartridges so that they are in tangential contact one with another. A cylindrical bore defines a second chamber 3b in the drum, an abutment or shoulder being formed between the two chambers. Into the rear end of each cartridge is inserted a cylindrical shank 12a of a sector shaped guide 12 provided with a shoulder 12c, which abuts the shoulder in the drum 3. Fastened to the push button 5 (Fig. 9 is a rod 4 which has one or several fingers (4a), which co-operate with notches (3d) in the top edge of the drum 3. With the drum 3 biased against the fingers (4a) by the spring 11, rotation of the push button 5 brings a selected cartridge into alignment with the eccentric opening 1a provided in the instrument barrel 1. A washer 7 fixed in the barrel also has notches (7a) which co-operate with the top edges of fingers (4a), thereby defining each angular position of the drum 3 to align each cartridge. An eccentric pusher 6 in which the rod 4 rotates, is fixed angularly with respect to the barrel and the washer 7, but slides through an eccentric hole (76) in the washer to contact the rear of the guide 12 of the selected cartridge when the pushbutton is depressed. When the selected cartridge is projected by depressing the button 5 (Fig. 11), the drum slides forward on the remaining non-selected cartridges which abut a shoulder 1b in the barrel 1. The cartridge is retained in the projected position by a known type of push-button actuated mechanism until the button 5 is again depressed and the drum 3 is released to be moved back by the spring 11. In an alternative embodiment (Figs. 14 and 15) the drum 3 is eliminated and the spring 11 acts as a single holding means for the cartridges which are bunched therein. The spring 11 is compressed between the shoulder 1c in the barrel and the shoulders 12c of the guides 12. Rotary movement is achieved with the fingers 4a inserted into the grooves (12d) formed between the guides 12.

Title: Improvements relating to pressure vessels
IPC: G21C9/004
Filed: 1971-12-29
Abstract: 1300180 Reactor pressure vessels COMBUSTION ENG Inc 29 Dec 1971 [30 Dec 1970] 60534/71 Heading G6C The pressure vessel of e.g. a nuclear reactor, comprises an external protective shield 30 formed of a number of elements retained in edge-to-edge relation under normal operating conditions of the vessel, the arrangement being such that, when the shield is exposed to an internal pressure exceeding a predetermined value, the elements will be displaced into spaced relation to relieve the pressure. The elements comprise a number of annular members 32 and lower and upper end members 42, 60. The annular members 32 are compressed between a flange 38 on the lower end member 42 and a flange 16 on an inner part 12 of th vessel. Tie-rods 34 extend between the flange 38 and a flange 40 of a locking collar 44 which engages flange 16, and a flange 62 on the upper end member 60 by way of shear blocks 66. Tie rods 22 secure the upper end member to a cover 18 of the inner part and to the flange 16. The tie-rods are pre-tensioned so as to maintain the elements in edge-to-edge relation during normal reactor operating conditions. The shield serves to suppress emissions from the reactor vessel in the event of serious accident and to contain fragments which might otherwise be expelled. The elements are sufficiently strong to prevent radial blow-out but the tie-rods can undergo slight axial expansion to permit annular venting spaces to be formed between the elements.

Abstract: 1363855 Foundry ladles STOPING AG 23 Dec 1971 [23 Dec 1970] 61004/70 Heading F4B Two refractory parts of a metallurgical vessel which are in contact with molten metal in normal use are joined by a filling of fibrous refractory material which does not react with the adjacent parts. The joint between a ladle bottom 1 and a pouring nozzle 2 is filled with a packing 7 of fibrous refractory material such as fibrous fused kaolin. A joint of 2-4 mm. width remains liquid tight, and since no bond is formed between the packing and the ladle bottom or the nozzle, the nozzle 2 may be easily replaced. A similar packing may be used between a ladle bottom and a porous brick or block to admit argon for flushing.

Title: Mounting Clutch Discs on Hubs
IPC: F16D13/68
Filed: 1979-11-30
Abstract: A clutch friction disc 12 comprises a hub 18 and an annular support 19 which can transmit torque to the hub 18 by teeth 24 on its inner periphery and has friction linings 20 on its outer periphery. The support 19 is mounted so as to be axially movable relative to the hub 18 and, in order to center it, between plates 13, 14, when the clutch is disengaged, it is subjected to axially acting elastic means, for example elastic lugs 26, which constantly urge it towards an axial positioning abutment 33 carried by the hub 18. This reduces or eliminates residual drag within the clutch after declutching. The invention is especially applicable to clutches used in semi- automatic transmissions. <IMAGE>
