Title: Disposable garments - having elasticated borders
IPC: A41D27/24
Filed: 1971-10-13
Abstract: Disposable garments e.g. briefs are formed by pref. providing aligned patches of adhesive on an advancing continuous web; cutting the web with a profiled cutter roller to define e.g. apertures and applying elastic tapes under tension along the edges of the apertures pref. by using guides associated with the cutter roll; securing the tapes to the web by pref. melting thermoplastic adhesive on the tapes using heaters associated with guides; similarly applying an elasticated tape to one edge of teh web to define a waist bandf folding the web over longitudinally; and cutting the web transversely in the region of the aligned adhesive patches (pref. using a cutter roll) thereby cutting out a blank and subsequently secure the adhesive patches together to form side seams of the briefs.

Title: Pump flow and pressure regulating valve - spring loaded bypass valve opens to recirculate fluid as outlet pressure increases
IPC: F04B49/24
Filed: 1974-06-19
Abstract: Pressure and flow regulating valve for pump discharge, receives fluid from the pump in a regulating chamber (94) from where it passes through orifices (111) in a valve seat (104), past a sealing disc (117) and exist through an outlet passage (18). This valve assembly is mounted on the end of a shaft (42), at the other end of which is a second valve assembly (26, 98, 99).

Patent FR-2301596-A1 (FR)
Title: Oxygen refining pig iron - with half the normal melt height to improve dephosphorisation
Inventor: TRENTINI BERNARD
IPC: C21C5/34
Filed: 1975-02-24
Abstract: In an O2 refining process for producing steel, in which O2 is infected together with a cooling agent such as a liq. or gaseous hydrocarbon, low P contents can be obtd. without reducing the C content to too low a level by reducing the height of the pig-iron melt above the O2 nozzles according to H >= Ho/2 1 + (Q-Qo/Qo) 1/2 where H is the height of the melt (in cm) corresponding to the O2 flow desired Q (in m3/min) and Ho is the usual height of the melt in normal practice corresponding to an O2 flow Qo so that a liq. slag esp. a dephosphorising slag is formed. The slag is formed early in the O2-refining operation and dephosphorisation is improved thus allowing high P contg. ores to be used. Since the C content is not too low the melt is not excessively oxidised. By reducing the height of the melt the effect is similar to that obtd. by increasing the rate of blowing or the dia. of each tuyere without the complications which arise from using these latter two methods. Thermal savings are made since the CO at the surface is burnt to produce CO2, steam is exothermically formed from the H2 evolved, and the O2 spends less time in the melt and therefore removes less heat. The higher temps. produced are also favourable to the formation of the slag. The increased temp. at the surface leads to greater dissolution of the limestone and inhibits foaming of the SiO2 slag which would greatly increase the apparent volume of the melt.
