Abstract: 914,067. Separating minerals by froth flotation. ILSEDER HUTTE. April 1, 1959 [April 1, 1958; Dec. 15, 1958], No. 11031/59. Class 41. [Also in Group II] Minerals are separated by conversion into a slurry which is then submitted to a froth flotation process in an electric field or with electrolysis, whereby ions present in the slurry are removed, and separation is improved. Preferably the electrical treatment zone is free from agitation of the liquid. In a suitable apparatus slurry is drawn from a chamber 4 through an aperture 5 into a diffuser chamber 6 to which air is admitted from a pipe 7 and the slurry is formed into a froth by rotating blades 7. The froth rises through a calming screw 9 into the surmounting electrical treatment chamber provided with plate anodes 3 and a perforated cathode 8, giving an electric field transverse to the rising gas bubbles. As an alternative the plates 3 may be arranged as anode and cathode, respectively, one or both of which may be insulated ; or a metal strip mounted on the chamber wall forms one electrode, the stirring device the other. Examples are given showing the improvement in separation of mixtures using a low voltage, and adding sodium lauryl sarcoside as flotation agent, including (1) limonite and quartz, (2) limonite and haematite sludges containing silica calcium carbonate and alumina.

Abstract: 906,818. Machine-tool details. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 1, 1960 [April 2, 1959], No. 11318/59. Class 83 (3). [Also in Group XXXIV] In a fluid bearing means are provided for measuring the variation in resistance to flow of fluid through a clearance space 6 and for varying the supply pressure to maintain constant the flow of fluid through the space. The resistance to flow through a restriction 2 is represented in Fig. 3 by a resistance R 1  and that through the clearance space 6 by a resistance R 2 . The pressure P s  of the fluid supplied from a valve 10 is connected to one end of the valve casing and the pressure P 1  of the fluid passing to the clearance space is connected to the other end of the valve casing. Since the areas of valve spools 13, 14 are in the ratio 2: 1 the pressure P 1  = ¢ P s . The resistance R 2  is thereby maintained as a constant proportion of R 1 , say 0.3 to 0.7 R 1 . Two such systems may be employed on the slide of a lathe, milling machine or profile checking machine as shown in Fig. 4, there being no need to ensure a fine finish on the main bearing areas 33, 34, 35, 36. To prevent damage in case of sudden loads or failure of the fluid pressure supply, pads 50, Fig. 5, may be used to convey the fluid to the auxiliary bearing surfaces 37, 39, 38, 40 of Fig. 4. The pads 50 are carried on rods 51 which can be moved axially against springs 54 if the pads contact the slideway. Such pads can be used on dividing heads, sighting instruments and vertical bearings. Additional conventional pads may also be provided.

Abstract: 1,168,883. Suppressed carrier modulation. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS BRANDT. 10 March, 1967 [31 March, 1966], No. 11477/67. Heading H3R. A balanced modulator/demodulator of the diode ring-type is characterized in that the usual input and output transformers are replaced by transistor circuits. In Fig. 2 an input signal E1 is supplied to a phase-splitting transistor 38, the outputs of which are fed by respective emitter-followers 53 and 54 to the diode network DN which is supplied with the carrier frequency E2 at terminal 80. The output terminals 76 and 78 of the diode network are coupled via emitter-followers 88 and 90 to transistors 104 and 106 which are connected in series push-pull and supply the output via filter 124. If the signal E1 is a suppressed carrier signal the output EO is the modulation and vice versa. In a modification, Fig. 4 (not shown), the carrier signal E2 is supplied to the same input circuit PS, but the diode network comprises two oppositely poled diodes joined by two pairs of resistances, the input signal E1 being supplied to the mid-point of one pair and the output signal EO being taken from the mid-point of the other pair via a filter, no output circuit being necessary. In a modification of this arrangement, Fig. 6 (not shown), the input circuit (PS<SP>1</SP>) comprises a pair of transistors (238, 339) sharing a common emitter resistance (248), the carrier signal E2 being supplied to one base and the other being at a fixed potential, the collectors being connected to respective load resistances and emitterfollower outputs. The circuits are suitable for construction as integrated circuits.

Abstract: 579,999. Automatic guns. RUAU, F. F., and MOLINS MACHINE CO., Ltd. June 15, 1943, No. 11479/44. Divided out of 579,984. [Class 92 (ii)] Relates to firing mechanism for automatic and semi-automatic ordnance of the kind in which the rounds are automatically fed to the breech, the sliding breechblock being opened automatically during run-out by a roller 6 on a crank-arm 5 engaging a cam 7 to compress a closing spring which is released by the insertion of a round to close the breech and fire the gun. According to the invention, automatic firing is prevented, when it is desired to fire by manual control, by moving a part of the fire control mechanism, such as the firing push-rod 33, to an inoperative position during the run-out movement of the gun. The invention is shown applied to an automatic gun as described in Specification 579,984 in which the push-rod operates on an abutment 36 of a lever 32 actuating the gun trigger mechanism as described in Specification 578,478. In the present Specification, a lever 15, operated by the roller 6 towards the end of run-out against the action of a spring 18, acts through a projection 41 on a member 40 depending from the pushrod to raise the rod clear of the abutment 36. To effect firing, a lever 39 turned on a pivot 38 by a hydraulic motor (not shown) first moves the push-rod to the left so that it falls about a pivot 37. to a position behind the abutment 36 and then moves the push-rod to the right to effect firing. The invention also includes the combination of the present invention with means for controlling the firing of the last round as described in Specification 579,998. Specification 578,477 also is referred to.
