March 10, 1931, No. 7393. Convention date, March 10, 1930. [Class 100 (ii).] Stereotype matrices are formed with a surface of the usual material and with one or more backing layers of a compressible material such as blotting-paper to enable the impression to be taken without the intermediate layer of felt usually employed. The backing can be applied during or after the production of the usual matrix material in large sheets or rolls which are cut to the required size. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of the material in the manufacture of matrices other than for stereotypes. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,130,021. Recovering oil from silt. R. &. H. GREEN, and SILLEY WEIR Ltd. 23 Feb., 1966, No. 7871/65. Heading C5E. A method for removing oil from silt and other solids comprises the steps of placing the oilbound solids in a closed casing having means such as a lid for introducing the oil-bound solids into the casing, introducing steam into the closed easing to condense to form a body of condensate immersing the oil-bound solids, and agitating the body of oil-bound solids and condensate, the casing having an outlet for oil freed from the solids, the said oil outlet leading from the level of the top of the body of condensate. Suitable apparatus may comprise a perforated drum 2 open at both ends and mounted for rotation about its axis which is inclined to the horizontal, the solids being introduced by hopper 9 into the upper end, steam being introduced by jets 17 through the perforated wall, the freed oil leaving over weir 14 and the de-oiled solids leaving by outlet 19.

Abstract: 1281462 EHT supplies INTERNATIONAL STANDARD ELECTRIC CORP 20 Feb 1970 [24 Feb 1969] 8282/70 Heading H2F [Also in Divisions H3 and H4] In an image intensifier system, stated to be known, in which the D.C. operating potentials for the image intensifier tube 10 (Fig. 1) are derived from a voltage multiplier 24 a current limiting resistor R being connected in the feed to the intermediate stage and the voltage multiplier being supplied with the output of an oscillator 26 the operating current of which is derived from a D.C. source such as a battery 28, the resistor R is omitted and a current limiting circuit 30 is provided which operates to supply a relatively constant current to the oscillator when the current drawn by the image intensifier exceeds a predetermined level. The limiting action commences when the voltage drop across emitter resistor 34 exceeds the reference voltage set by Zener diode 38 at which point the emittercollector impedance increases so that the voltage drop across the latter increases and that across resistor 34 and across the load presented by the oscillator decrease. Thus the battery "sees" a relatively constant impedance which is supplied with a constant current. An advantage of the invention is that the image intensifier is usable over a wider range of input light levels whilst maintaining a reasonable level for observation on the output display screen after amplification than was the prior art system.- Thus the present invention also prevents damage to the intensifier tube by excessive peak current. The battery voltage may be 6À75V. D.C. the Zener reference voltage 2À7V. D.C., the oscillator output voltage about 2800 peak-to-peak and the three stages of the image intensifier may be supplied with 8-14kV., 26-30kV. and 39- 42kV. respectively.

Filed: 1978-03-02
Abstract: Each part (2) of the clothes stand comprises a support part (3) which is telescopically displaceable therein for the selective setting of the vertical position of the bearing devices (38-40) on the clothes stand. To fix the position of the support part (3) relative to the stand part (2), the support part (3) bears at its lower end a clamping block (15) with a blocking roller (14) which can be controlled from the outside of the support part (3) and is intended to produce a frictional locking engagement between the support part and the stand part (3, 2). The blocking roller (14) is guided in a forked control member (10) at the lower end of an actuating rod (7) and is clamped firmly in terms of operation between a sloping clamping surface (18) and an inner surface of the stand part. To release the said blocking engagement, the control member (10) together with the blocking roller is pushed outwards by means of the actuating rod (7), in which case the blocking roller is disengaged from the stand part along the sloping clamping surface (18). <IMAGE>

Title: Removing latex cream from top surface in creaming tank
IPC: C08C1/08
Filed: 1957-03-14
Abstract: <PICT:0807006/IV (a)/1> <PICT:0807006/IV (a)/2> Concentrated latex is obtained by allowing latex containing a creaming agent to stand in a tank to form an upper cream layer and a lower serum layer, and separating the cream by withdrawing it through a vertically adjustable pipe situated inside the tank.  A creaming tank 10, Fig. 1, has a pipe 11 for introducing latex containing a creaming agent, and a vertically adjustable pipe 14 for withdrawing the cream slidable within an outlet pipe 12.  The upper end of the pipe 14 is provided with a funnel 15 having radial vanes 17 and secured by a bracket 16 to a screw 18.  The latter passes freely through a support 21, Fig. 3, and carries a nut 24 rotatable on a ball-bearing 25 and held against vertical movement by a flanged ring 26 secured to the support 21.  A lock-nut 27 may be tightened against the nut 24.  When it is desired to raise or lower the screw 18 and the pipe 14 the lock-nut 27 is separated from the nut 24, and the latter is rotated by arms 23.  In a creaming operation latex containing a creaming agent is admitted through the pipe 11 to a level just below that of the funnel 15 (as shown in full lines).  After a few days but before a thick butter layer can form the funnel 15 is lowered to a height just above the interface between the cream and the serum, and the cream is run off through pipes 14, 12.  This procedure is repeated after each of a number of further standing periods, and when no further cream is obtainable the funnel 15 is lowered to the interface.  The lock-nut 27 is then tightened against the nut 24, and the latter is again operated and now rotates the screw 18 and the vanes 17 which are curved to push the cream into the funnel 15. After removal of all the cream the serum is withdrawn through the pipe 11.
