Title: Liquid Level Measuring Instrument
IPC: G01F23/26
Filed: 1980-09-19
Abstract: An analogue liquid level measuring instrument for use with electrically conductive liquids comprises primary and secondary induction coils 1, 2 spaced apart in end-to-end relationship on a common axis A', the coils being wound on a pair of elongate formers 3, 4 of magnetically inductive material. The formers are arranged to enshroud 3a, 4a one end of each coil in such a way that in use the magnetic flux is induced to pass through the liquid. The screening action of the liquid produces a relatively large change in output signals generated in the secondary coil between the covered and uncovered states. The pairs of coils and associated formers are housed in a non-magnetic steel pocket 'p' which is immersed in the liquid to be monitored. Alternatively the coils and formers are disposed outside the pipe with the unshrouded ends of the coils being directed towards each other. <IMAGE>

IPC: B29C63/00
Filed: 1983-05-06
Abstract: A method of producing fiber- reinforced glass composites of complex shapes (e.g. having curved portions such as cylindrical) is disclosed. A continuous length of fiber, such as silicon carbide, is passed through a slurry of glass powder and a carrier liquid containing a polymeric binder to impregnate the fiber. The impregnated fiber is next dried and woven into a predetermined structural shape. Plies of the woven fiber cut to near net shape may also be stacked into the desired shape. The thus laid fibers are hot pressed into a fiber reinforced glass matrix composite article having glass matrix distributed substantially uniformly therethrough and multiaxial strength in at least three mutually exclusive perpendicular directions. Fig. 1 is a photomicrograph of such an article. <IMAGE>

IPC: A23G9/28
Filed: 1983-10-21
Abstract: In a process for producing filled pastry products 36 that comprise at least two superimposed layers of cake and an intermediate layer of filling, a continuously advancing stream of cake 22 is subdivided by means of vertical longitudinal cuts 25 spaced from each other by a distance equal to the thickness of each cake layer of the finished filled product.

Title: Rolling mill
Inventor: SCHIRMAG KLAUS-PETER
IPC: B21B17/14
Filed: 1984-08-15
Abstract: A rolling mill for reducing and sizing rolling of pipes has several roll stands arranged successively in the direction of rolling. Each roll stand has two driven rolls 1 and the rolls in successive stands are arranged rotated through 90 DEG  about the rolling axis with respect to each other. Non-driven rolls 2 are arranged between the two driven rolls 1 in each stand, and the looping angle 8 of the driven rolls 1 is greater than that of the non- driven rolls 2. Groove wear is substantially reduced, so that with respect to the relative speed between roll and pipe, rolling conditions are produced similar to those of a 3-roll stand but with a much simpler initiation of moment of rotation and roll mounting. <IMAGE>
Patent GB-2145889-A (GB)
Title: Analog-to-digital conversion
Inventor: FRANKLIN MICHAEL JOHN BARRY
IPC: H03M1/00
Filed: 1984-08-22
Abstract: A successive-approximation type of analog-to-digital converter which, to increase the effective conversion rate, comprises a series of comparison stages C1 -C8 operable, on a pipeline basis, to form respective bits of a digital signal corresponding to a received analog signal. The first stage C1 compares the received analog signal A with a fixed reference VF and, depending on the result of the comparison, generates an appropriate bit value (to register DR1) and passes on to the next stage by means of analog register AR1 either the same value of analog signal or the difference between that value and the reference. Each subsequent stage, apart from the last, carries out the same operation vis- à-vis the analog signal passed to it by the next preceding stage. The last stage C8 carries out a comparison operation and generates a bit value (to register DRS) but of course does not need to pass on any analog signal. The comparison signals fed to the respective stages may be in binary sequence (as shown) or may be all the same in which case an analog signal doubling element is provided between each two adjacent stages (Fig. 2). <IMAGE>
