Abstract: 328,780. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). April 22, 1929. Resistance furnaces. - In an electric furnace for making sodium sulphate, a rotary tube A, traversed by an axial tube B on which is mounted a worm C adjoins a fixed member D provided with a hopper E and inlet and outlet pipes K, F. The rotary tube A is provided with a lagged electric heater divided into sections J. Small porous pellets of rock salt, prepared as described in Specification 269,209, [Class 87 (ii), Moulding plastic &c. substances], are fed into the hopper E, guided through the furnace by the worm C, and are acted upon by the reaction gases, which, after being preheated by passing through the tube B, issue through openings H into the furnace chamber, finally passing out through the outlet F. The sodium sulphate produced is carried by the worm into a zone free from sulphur dioxide, cooled and discharged at the hopper G. The reaction temperature is maintained between 460‹ C. and 520‹ C. and may be regulated by turning sections of the electric heater on or off or by detaching portions of the lagging.

Patent GB-126216-A (GB)
Title: Telephone Exchange Systems.
IPC: H04M5/10
Filed: 1918-08-01
Abstract: 126,216. Western Electric Co., (Western Electric Co.). Aug. 1, 1918. Semi-automatic and manual exchange systems.-In systems in which manual lines and automatic lines (or trunks to automatic exchanges) terminate in the same exchange, and in which the same connecting means (cord-circuit) is used to connect to both types of lines, when connexion is made with a manual line, ringing-current is automatically supplied to the line, and the operator's impulsesender disconnected, whereas when connexion is made with an automatic line, the impulsesender is connected up and the ringing-current disconnected. Operation when calling line A is connected by cord C to manual line B. On the insertion of the calling-plug, the test relay 18 and the marginal relay in series therewith are both energized, the resistance of the cut-off relay 19 being low compared with the resistance 20 connected to the jack 21 of automatic lines. The relay 18 energizes relay 26 over lamp 25, upper winding of relay 26, back contact of relay 27, and normal contact of ringing cut-off relay 28, whilst the marginal relay disconnects the impulsesender 46, energizes a relay 36, and connects ringing-current through the relay 28, lead 30, called line, lead 29, and upper front contact of relay 36. When the called subscriber removes his receiver, relay 28 is energized and opens the shunt around the upper winding of relay 27, which energizes in series with the upper winding of relay 26, and short-circuits the latter over contact 39. Relay 26 is thus de-energized and completes the talking circuit over relay 40, which shunts the supervisory lamp 25. Microphone current is supplied over the contacts of relay 36. Operation when connexion is made to automatic line F over trunk D. On the insertion of the calling plug in jack 21, relay 18 is energized but not the marginal relay. Relay 26 is energized over its upper winding as before and connects the impulse-sender 46 and relay 49 over the lead 29, 30 and trunk D to the selector E, where the circuit to battery includes the lower winding of relay 52, contact 51, and side-switch arm 50. The relay 49 energizes a slow-release relay 55, which closes a circuit through the lower windings of relays 26, 27, both of which remain energized. The selector is operated in the usual manner by the impulse-sender 49, and when the side-switch arm 50 reaches its third position, a resistance 59 is thrown into the trunk circuit, thereby deenergizing relays 49, 55, and 26, relay 27 remaining energized over its upper winding. The repeater and supervisory relay 40 are thus connected through to the called line, and when the subscriber removes his receiver, the back-bridge relay 62 short-circuits the resistance 59, thereby energizing the relay 40 and extinguishing the lamp 25. As the relay 36 is not energized, the called line is supplied with current from the automatic exchange.

An attachment for the customary handoperated drilling and slotting machines for wool-combs enables the drilling, slotting, and indexing operations to be performed automatically and comprises a double cam, a sliding member with rollers engaging the cam faces at opposite sides thereof, a lever and pin connecting the sliding member and drilling spindle, and an intermittently operating gear device which indexes the workpiece while the drill is withdrawn therefrom. The attachment comprises two saddle members b, b<SP>1</SP>, supported on the machine slide a, the latter saddle member being connected to move with the drilling head saddle b<SP>2</SP> (normal parts of the machine shown in broken lines, attachment parts in full lines). Bearings in the attachment saddle members support a pair of shafts h, h<SP>1</SP>, the former being driven through a pulley p<SP>1</SP> from the normal driving shaft below the saddles. A pair of cams k, k<SP>1</SP>, of similar periphery but oppositely spaced, are keyed to the shaft h and control the movements of a transverse sliding member j. This member is adapted to remain stationary during a quarter of a revolution of shaft h and to feed the drill spindle q and retract it during the remaining three quarters of a revolution. The sliding member j is connected for this purpose by a link n and lever o to the drill spindle q. The forked end of the lever o having one limb connected to a slide v which carries an adjustable abutment s engaging the spindle-end for the inward movement, and the other forked end having an abutment which engages a groove p in the spindle for retracting it. The shaft h also carries a toothed wheel u, Fig. 4, and a plate u<SP>1</SP>, the wheel engaging a pinion v on the shaft h<SP>1</SP> which is a quarter the diameter of the wheel. Pinion v also has a plate v<SP>1</SP> adjacent thereto, the plates interengaging to produce an intermittent movement of shaft h<SP>1</SP> which is transmitted through gearing w, x, to the usual indexing gear for the workcarrying table (not shown). For slotting the holes in the wool-comb ring after drilling, the drive to the drill spindle is disconnected and a slotting tool is secured in the spindle chuck in place of the drill. The same driving mechanism is employed, the first strokes being made by hand to position the tool, the link o being disconnected and used as a hand-lever for this purpose. Slotting tools of increasing size are employed until the rectangular holes in the comb-ring are completed to size.

Title: Gyromagnetic resonance apparatus
IPC: G01R33/46
Filed: 1959-10-14
Abstract: 939,258. Frequency changing circuits. VARIAN ASSOCIATES. Oct. 14, 1959 [Oct. 16, 1958], No. 12679/63. Divided out of 939,257. Class 40 (6). An oscillator comprises a gyromagnetic substance in a unidirectional magnetic field, a radiofrequency magnetic field at an angle to the unidirectional magnetic field, the radio frequency field being modulated so as to provide gyromagnetic resonance at a side band frequency, the resonance signal being amplified and detected so as to produce the modulation frequency which is fed back to the modulator so as to maintain oscillation at the side band frequency. In Fig. 7, the output of a radiofrequency oscillator 81 is amplitude modulated at 82 so as to excite a gyromagnetic sample into resonance at a side band frequency, the resonance signal being amplified and limited at 84 and passed to a discriminator 85 to provide the modulation frequency which is fed back to 82 to sustain oscillation at the side band frequency. In Fig. 8 the radio frequency wave is frequency modulated and an amplitude modulation detector is used. The effect of modulating the polarising or excitation fields in gyromagnetic apparatus is explained with the aid of Figs. 1-6 (not shown) which form the subject matter of Specification 939,257 [Group XXXVI].

Title: Improvements in apparatus for forming the combustible charge for an internal combustion engine
IPC: F02M69/40
Filed: 1958-04-23
Abstract: 826,377. Charge forming apparatus. GENERAL MOTORS CORPORATION. April 23, 1958 [May 9, 1957], No. 12877/58. Class 7(3) Apparatus for forming the combustible charge for an internal combustion engine comprises an air induction system and a fuel injection system having a fuel metering mechanism actuated by a signal the force of which varies with the mass of air flowing through the induction system, and a device for supplementing the force of the 'signal with a further force which is modulated in accordance with temperature engine load and air flow to provide an enriched fuel air mixture when the engine is cold. As shown metered fuel from the valve 22 is supplied to conduits 26 which communicate with the individual cylinder intake passages 20. In order that the metering control force acting on diaphragm 32 may be reinforced in inverse proportion to engine air flow and temperature so that when the engine is coldest a maximum metering, signal will be generated and the metering valve 22 be maintained in its maximum fuel output position and when the engine warms up such reinforcement of the metering signal will progressively diminish, a signal modulation choke valve 50 is employed. The valve 50 is controlled by a bimetallic coil 60 and the force with which the coil retains the valve 50 closed varies inversely with temperature. The valve 50 is responsive to manifold vacuum which acts on a piston 64. If it is desired to adjust the operation of the signal modulation valve 50 for a particular stepwise operation it is possible to provide a passage 76 in the piston 64 which is adapted to provide an air bleed to reduce the effectiveness of manifold vacuum on the piston 64 during certain phases of engine operation a conduit 78 being formed in casing 68 to communicate at opposite ends with the piston bore and the chamber 80. After the engine begins to fire manifold vacuum will shift the piston 64 to a position in which the conduit 76 communicates with the conduit 78 so a to reduce the manifold vacuum force acting on the piston. Conduits 76, 78 may be omitted. A fast idle cam having a stepped cam surface may be controlled by the bimetallic coil 60. A pair of signal modifying valves 100, 102 may be used, as shown in Fig. 4. The heat responsive control mechanism may be mounted away from the signal modulation valve shaft.
