Title: Pneumatic riveting machine for securing trim strip - has pneumatic telescopic driving rod guided by slot to rivet holding
IPC: B25C1/00
Filed: 1975-06-03
Abstract: A riveting machine suitable for securing vehicle trim strip by plastics button rivets, and where there is access from one side only, used special bulbous bodied rivets (1) with their domed heads attached to one another to form a strip.

Title: Automatic beverage maker with centrifugal action - has brewed coffee outlet channels along facing edges of bowls forming chamber
IPC: A47J31/22
Filed: 1976-04-14
Abstract: A coffee or tea making machine has two bowl-type members (13, 14) which fit together along their outer edges to form a centrifugal chamber (15) with outlet channels for the brewed drink. These channels are formed by recesses spaced from each other along at least one of the opposing outer edges of the bowls (13, 14). These bowls are in connection about a first stretch along their axis of rotation and can be displaced about a second stretch so that they can be moved towards and away from each other. Since the outlet channels leading out of the centrifuge chamber are mounted spaced from each other along the opposing outer edges of the bowls, any residue formed by the coffee can be completely and easily removed, since the channels are completely opened when the bowls are separated from each other.

Title: Heat-forming mould punch with gas pressurised punch to sheet interface - to reduce friction and slip angles when forming preprinted blanks
IPC: B29C51/04
Filed: 1976-07-13
Abstract: Thermoforming tools comprise a punch which is drilled to discharge a pressurised gas between the face of the punch and the thermoplastic sheet during deformation of the sheet so as to reduce contact between the punch and the sheet draw angle around the edges of the face of the punch. Arrangement is used for forming hollow mouldings from materials having a high elongation to break (e.g. 700%), esp preprinted blanks where controlled deformation of the blank is essential to obtain the required print pattern on the formed moulding. The sheet material is subject to lower drag forces and cooling rates during deformation than if in contact with a metal punch surface. Gas exhaust keeps the cavity purged of dust or fumes.

Title: Tuyere for bottom blown steel-making converter - has means to compensate for differential thermal expansion between concentric pipes
Inventor: ZANETTA HUGUES
IPC: C21C5/48
Filed: 1977-02-11
Abstract: Tuyeres adapted for the bottom blowing of steel-making converters and partc. for supplying refining agents to the converter, comprise one or more concentric pipes defining annular channels between them to permit the separate supply of different refining agents. The inner pipes can slide axially independently of the outer pipes and comprise individually resilient means tending to propel the inner pipes toward the interior of the converter and means to lock the pipes in propelled position once movement towards the converter has occured. The tuyere is of simpler construction than conventional bottom blow tuyeres being free of screw portions. Thus the tuyere is less subject to thermal stree set up as a result of differential thermal expansion being the various tuyere pipe constituents.

Title: Prepn. of sulphonic di:esters of butene-di:ols - by electrolytic anodic oxidn. of butadiene, sulphonic acid and ether cpd. mixt.
Inventor: BAUDOUIN MICHEL
IPC: C25B3/23
Filed: 1977-03-03
Abstract: Sulphonic diesters of butenediol are prepd. by electrolysing a medium contg. butadiene, a sulphonic acid and an organic cpd. with an ether function. Pref. cpds. with an ether function are a dialkyl oxide with b.pt. >50 degrees C (e.g. propyl or butyl oxide), a dialkyleneglycol (with alkyl of 2-4C, e.g. diethyleneglycol) or a polyhydroxylic polyalkyl-eneglycol. In latter types, OH gps. are wholly or partly blocked as gps. that are neither oxidised nor reduced under thereaction conditions. e.g. alkoxy gps. The process gives much higher yields of diesters, esp. diesters of 2-butene-1,4-diol. These prods. are very important industrially as starting materials for prodn. of butane-1,4-diol.
