Title: A new or improved process for producing bricks, tiles or other moulded-articles fromgranular or powdered clay or other materials
IPC: F26B11/02
Filed: 1938-09-21
Abstract: 505,652. Rotary driers. HUMPHRIS, F. Sept. 21, 1938, No. 20902/37. [Class 34 (ii)] Bricks, tiles or other articles moulded from clay or other materials are produced and dried by feeding the raw material into a slightly inclined drying drum, which has a tubular shell a with a central conduit a<3>, chambers y and baffles or shelves a<1> therein and is intermittently rotated on rollers e by continuously oscillating pawls h<1> moved by bell-crank levers i, connecting rods k and a variable stroke crank-pin m on a rotary driving shaft n, said pawls h, h<1> engaging teeth g<2> on an annular ring g on the shell. The granular material is fed from a hopper b to rotating angle blades on one end of the drum and passes by gravity to the other end, where hot gases enter, the material then passing to a grinding mill and while hot to a moulding machine. The material enters and leaves the drum through rotary wheel devices excluding outside air from the drum. Waste heat from a kiln is admitted through an upper duct c', hot air through a central duct c<2> and cool air through a duct c', the ducts having dampers r. A stationary baffle directs some hot air into a central air duct a<3> carrying external stirrers and a removable extension carrying the angle blades. The shell has telescopic or 'bellows-like packing at one end to allow for expansion, and the gas passes out at u. A counterweight lever p bears on the rod k to ensure engagement of the pawl h with the teeth g. The crank-pin m is mounted on a plate m<1> with studs m<2> engaging preselected holes n<1> in a rotary driving plate n so that the pawl moves through a distance of one to four teeth g. The material may also be moved through the shell by slides or screw devices.

Title: Improvements in or relating to electro-magnetic apparatus specially suitable for use as a relay, switch, or like device
IPC: H01H51/22
Filed: 1920-09-10
Abstract: 172,717. Carpenter, R. E. H., Creed, F. G., and Creed & Co., Ltd. Sept. 10, 1920. Electromagnets.-An electromagnetic device, which may be used as a switch or relay or may actuate a valve, consists of two oppositelypolarized magnetic elements each having polar extensions, thereby forming two air gaps, and a magnetic armature pivoted centrally and having its ends :in the respective air gaps, the armature being magnetized by a stationary coil surrounding it; the polar extensions producing a transverse flux localized beyond the extremities of the armature coil. The magnetic parts are so proportioned that a small variation in the magnetizing current or a reversal thereof produces a large variation in the transverse flux and causes the armature to move over from engagement with two diametrically opposite poles to the other two. Themagnet system consists of two U-shaped elements built up of laminµ arranged to form two air gaps a<1> b<1>, a<2> b<2>, Fig. 1, and leaving a central space for the magnetizing coil d of the armature. In the form shown in Fig. 3, the magnet system is constantly magnetized by coils e<3> surrounding cores bolted to the magnetic elements and connected together by an annular yoke e. The yoke may be permanently magnetized and the coils e<3> dispensed with. Permanent-magnet polar elements may, however, be employed, in which case the core and the yoke are dispensed with. The coil is placed in position and the armature, which consists of a built-up long-laminµ structure, with two projecting strips which may carry contacts, is pivoted within a framework threaded through the coil so that the ends of the armature lie near the pole-faces. The armature may be free from control and, in this case, in order to reverse its position from the position in which it is magnetically held, as shown in Fig. 1, it is necessary to reverse the current through the winding d. Alternatively, the armature mav be held in one position against the return action of a spring by current in the winding d and, if this current is reduced, the spring reverses the armature. The armature has a substantially smaller cross-section than the fixed magnet structure and, consequently, the reluctance of the fixed structure and the hysteresis and eddy current losses therein are small relatively to those of the armature. In a modified construction a hollow magnet structure 8, Fig. 8, is provided with a polarizing coil 9 having two internal oppositely-arranged polepieces built up of laminae.

Title: Improvements in honing machines
IPC: B24B33/02
Filed: 1939-09-19
Abstract: 529,567. Honing tapered bores. BURGESS, A. F. (Barnes Drill Co.). Sept. 19, 1939, No. 26141. [Class 60] In honing long tapered or other bores in which tool and work are relatively reciprocated and rotated, the tool is expanded by power actuated means to apply a light pressure during relative travel in one direction and increased pressure in the other. The increase may be gradual but preferably it is increased to a maximum as soon as the direction is reversed. The work W is fixed and the tool 11 is rotated by an electric motor M2 and expanded, within the bore 20, by closing a switch SW by hand to energize a solenoid S<SP>2</SP> and move the valve V<SP>3</SP> into the position shown, whereby fluid from a pump P<SP>1</SP>, driven by the motor M<SP>2</SP>, is admitted to a cylinder 17 and thus advance the cams 14. The tool is reciprocated by cables 21, 22 connected to a drum 23 rotated by a reversible hydraulic motor M controlled by a valve V<SP>1</SP> which is operated by a pilot valve V<SP>2</SP> under the control of solenoids S, S<SP>1</SP> and switches LS, LS<SP>1</SP> operated by a projection 27 on the tool-slide at each end of its normal travel. When the tool moves to the right a frictionoperated switch SW1, carried by the tool-slide, is opened. The valve V<SP>6</SP>, however, also connects the pressure fluid to a relief valve V' adjusted to reduce its value so that the tool pressure is light. As soon as the direction of movement is reversed the switch SW<SP>1</SP> is closed, solenoid S<SP>3</SP> energized, and valve V<SP>6</SP> rotated to connect the fluid pressure supply to a relief valve V<SP>5</SP> adjusted to a higher value than V' so that the tool is expanded with greater force. When the machine is used for non-tapered work the switch SW2 is opened by hand.

Filed: 1967-06-09
Abstract: 1,148,840. Measuring frequencies digitally. STANDARD TELEPHONES & CABLES Ltd. 9 June, 1967 [15 June, 1966(3)], No. 26736/67. Addition to 1,047,534. Heading G4A. Apparatus of the type disclosed in Specification 1,047,534, is modified. To ensure greater accuracy in measuring the frequency of pulses c against a standard frequency, counting is inhibited until the timing period pulse on a and a pulse on c are simultaneously in condition 1 so that AND gate 13 reverses bi-stable 20 which opens gate 25. The ensuing pulses on c are then counted at 28 and displayed at 30 until the pulse at a ends. If the frequency c is an exact multiple of frequency a, AND gate 13 may never open so provision is made for initiating a count by by-passing 13 after a delay. A forced count is appropriately indicated. As in the parent Specification, the frequency is displayed at 30 with adjustment of the decimal point 31. This adjustment is dependent on whether or not carry has been effected from decade C to D. To guard against extending the measuring period ten-fold when such carry is imminent the bi-stable 37 which measures off the decimal period responds to the attainment of 9 in decades C, B, A simultaneously. As an alternative the connection from A may be permanently marked.

Title: Improved process for the refining of alloys
IPC: C22C3/00
Filed: 1934-09-20
Abstract: A process for obtaining low-carbon alloys consists in so disintegrating an alloy which comprises constituents of different carbon contents that the constituents are completely or to a large extent liberated from each other, and thereafter removing from the product the constituents of higher carbon content, for example by screening, air separation, or washing; the separation may be repeated a number of times.  An element such as silicon, aluminium, nickel, or titanium may be added to an alloy in order to cause it on solidification to separate into constituents of different carbon contents; or in the production of alloys such as of silicon with iron, chromium, manganese, or vanadium, silicon may be used as the reducing-agent for ores or oxides or slags rich therein, for example in the form of a silicon alloy; or it may be used in the form of quartz along with a carbonaceous reducing-agent.  In an example, an iron-chromium-silicon alloy containing 37 per cent. of chromium, 45,7 per cent of silicon, and 0,32 per cent of carbon is crushed and classified yielding three products containing respectively 0,1, 0,18, and 2,1 per cent of carbon.

Abstract: 933,854. Semi-conductor devices. THORN ELECTRICAL INDUSTRIES Ltd. Nov. 26, 1959 [Aug. 26, 1958], No. 27388/58. Class 37. [Also in Groups XXXVIII and XL (a)] An electric coupling device comprises a plurality of conducting strips on an insulating support and a plurality of sets of electrodes, each set having portions operatively adjacent portions of an individual combination of the strips and separated by resistance or dielectric material so that the impedance between a set and each of the strips of its associated combination is less than between that set and any other strip. Fig. 1 shows an assembly of nine electroluminescent lamps A-J on a conducting layer 11 on a glass base 10, which can be operated selectively to display figures 0-9. The necessary switching arrangement consists of a glass plate 13 carrying conducting strips 14-21 covered by a layer of voltagevariable resistive material such as silicon carbide. Sets of electrodes 0-9 are arranged to contact the silicon carbide at selected regions overlaying the conducting strips to provide individual combinations corresponding to the connections necessary to display a particular numeral. When a voltage is applied from A.C. source 22 via selector switch 22 to one of the electrode sets, the impedance of the silicon carbide between each electrode and the conducting strip falls to provide the connection. In an alternative arrangement the electrodes are arranged alongside each conducting strip instead of above. Dielectric material may replace the silicon carbide, if a high frequency (20 mcs.) signal is used.
