Abstract: 923,522. Ammunition fuzes. RHEINMETALL G.m.b.H. June 10, 1960 [June 12, 1959], No. 20570/60. Class 9 (1). In an electric fuze for ammunition in which a condenser 5 for firing an electric detonator 7 is charged electrostatically by the escape of a powder as in Specification 751,579, one pole of the detonator is connected to the condenser and the other pole to a percussion member 8, the circuit being completed on impact by contact between the fuze nose 3 and the member 8 as in Specification 923,523, whereupon the condenser 5 can discharge through the detonator 7. Between the nose 3 of the fuze and the body 2 is high quality insulation 4 and a connection between the body 2 and the condenser 5 is interrupted by a spark gap. If the capacity of the condenser is, say, 5000 ÁÁ F, the gap capacity is 5 ÁÁ F. The spark gap may be replaced by a discharge tube or a rectifier may be used to prevent accidental firing of the detonator. Specification 923,521 also is referred to. Reference has been directed by the Comptroller to Specification 751,579.

A magnet 1 of a SmCo 6  alloy produced by powder sintering is attached to a soft iron body 12, e.g. the pole shoe of an electrical machine, by brazing at surfaces 4, 5 with the intervention of a foil 3 of silver or copper. The surfaces are ground, cleaned with ethanol or acetone, and opposed over the foil, and then introduced in a holder into a cooler zone of a sintering furnace containing protective gas. The unit is then introduced into an annealing zone at temperature slightly exceeding the m.p. of the foil for brazing, i.e. about 7,000 C., and transferred to the cooling zone for rapid cooling; after which it is heat-treated for an extended time at 850-950 C. At the junction point an ironcopper or iron-silver alloy is formed in the boundary region to constitute a strong connecting layer. The brazing layer may be deposited electrolytically. The body 2 may be of an iron alloy with similar temperature coefficient of expansion to the permanent magnet. The brazing layer may be of gold, nickel, tin, or alloys thereof, or of copper gold, copper gold nickel, copper silver, gold nickel, copper tin silver, copper gold silver, alloys in various proportions which are quoted. Plural iron bodies may be conjoined to the magnet.

The temperature of the filaments may be regulated by resistances w with the object of eliminating disturbing signals. The coils g are aperiodic and strongly damped, and are loosely coupled to the coil s, which may be tuned to the incoming waves. Switches may be arranged for interchanging the connexions of the coils g to the valves v for the purpose of obtaining the mean of two readings. The coils g may be arranged to control the position of a magnetic needle for indicating the direction of incoming waves. Two coils may be used in place of the single coil S. In another arrangement, the aerials are connected across the grids and plates of the valves. The Specification as open to inspection under Sect. 91 (3) (a) states that one of the valves may be arranged to act as an oscillation producer for heterodyne reception. A modification is also described in which a single valve is connected by a switch to any one of a series of aerials. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 124,786.

Title: Improvements in or relating to the separation of materials of different specific gravities

Abstract: 415,881. Washing granular materials. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Chance, T. ; Merion, Pennsylvania, U.S.A.) July 26, 1933, No. 21052. [Class 82 (ii).] In the sand-flotation process a rotary movement is imparted to the lower portion of the suspension of sand in water and the rotary movement of the upper portion is suppressed so that the lighter material passes across the vessel, either to an overflow or to a discharge aperture below the surface of the suspension, in a substantially rectilinear path. The suppression of the rotary movement in the upper portion of the suspension may be effected either by providing a relatively deep column of suspension above the means which produce the rotation, or by the provision of baffles, or by a combination of these means. In the form shown, the upper portion of the vessel 1 is of rectangular cross-section and the lower portion is conical. An upward current of liquid is introduced at 2, preferably into a column 1<a> containing liquid of lower specific gravity than that of the suspension in the vessel 1, and this liquid is distributed by imparting a rotary movement to the suspension in the conical part of the vessel by means of a rotary agitator 4. A plurality of agitators, or high speed impellers, or tangential liquid jets may be employed to produce the rotary movement and additional liquid for agitating the mass may be introduced through the pipes 7. Baffles 11 are provided to suppress the rotary movement in the upper rectangular portion of the vessel and jets 12 are preferably provided to maintain the fluid properties of the suspension in the corners of the vessel. The material to be separated is fed, with or without water, into a hopper 8, and the discharge into the vessel 1 is controlled by adjustable gates 9, 10, the pressure of the column of material in the hopper 8 being sufficient to force the material under the surface of the suspension. A mixture of the suspension and water is fed by a pipe 6 either to the hopper 8 or to the surface of the suspension in the vessel 1 and carries the light material across the vessel to a discharge overflow 5, the liquid discharged with the light material being returned to the pipe 6. The opening of the hopper 8 and the discharge 5 may extend the full width of the vessel. Jets 13 are provided to maintain the fluid properties of the suspension below the opening from the hopper 8 and the overflow 5. Alternatively, the light material may be allowed to sink as it passes across the bath to a discharge aperture situated below the surface of the suspension. The heavier particles are removed from the lower portion of the vessel, for example by the means described in Specification 396,558.

A butterfly valve for controlling the flow of gases comprises a tubular aluminium alloy valve body 1 housing a thin deformable stainless steel sleeve 8 secured in the body by a supporting sleeve 12. The sleeve 8 is a loose fit in both the body and the sleeve 12 but has an interference fit with the butterfly disc 5 so that on moving the disc into its closed position in the body the sleeve is deformed to provide a seal. The sleeve 8 is mounted on the down-stream side of the disc so that gas pressure acts on the outside of the sleeve 8 to assist in the sealing of the valve. In an alternative construction the sleeve 12 is dispensed with, the outer end of the sleeve 8 then being made thicker and screwed into the body.

Title: Improvements in and relating to document reader checking circuits

Abstract: 880,341. Record sensing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 17, 1960 [June 29, 1959], No. 21317/60. Class 106 (1). The correct operation of a photo-electric record sensing apparatus is checked by having a photo-cell 11, Fig. 1, adapted to sense a series of commutator marks 10 and a number of data sensing photo-cells 7 each of which senses a check mark 23 at a particular position on the record. The commutator marks are counted and an output is produced at the position of the check marks. If the photo-cells 7 are working correctly each should detect a check mark at the instant the counter gives the output. The signals from the photo-cell 11 pass, after amplification, to a counter having two decades 14, 16, Fig. 2. The stages are connected to the horizontal and vertical lines of a diode matrix 20 plugged at 21 to produce an output at a selected count e.g. 73 as shown. The check marks 23 are arranged at this position on the record and the signals from photo-cells 7 are gated with the output from the matrix 20 to fire cold -cathode storage tubes the outputs of which are all connected to a coincidence circuit controlling the operation of the machine or an error indicator. If any photo-cell 7 fails to detect a check mark at the instant the 73rd commutator pulse is detected, a misfunctioning is indicated. If there is data on both sides of the record, there may be a similar sensing and checking provision on both sides, the signals being combined. Specification 879,414 is referred to.
