Abstract: 1,035,104. Air-heating stoves. R. D. PORTER. Jan. 25, 1963, No. 3209/63. Heading F4S. An air-heating furnace is prefabricated in sections 11a, 11b adapted to be inserted in an opening in a floor, the section 11a containing a blower 25, and the section 11b containing a burner 15, flame tube 19, combustion chamber 17 and a heat exchanger 20 heated by the burner gases (see Fig. 2, not shown). Each section is supported in the floor opening on flanges 92, 94 and is open at the top. In use, the open tops of the sections are covered by a grille (not shown). Air is drawn by the blower 25 downwardly into the section 11a and is thereafter forced through an opening 27 in an end wall 23 of the section 11b (see Fig. 4, not shown), into that section whence the air passes over the combustion chamber and heatexchanger and discharges upwardly through the grille and into the room. To assemble the furnace sections in a floor opening 123, extending unequally on each side of a wall W, Figs. 6 and 7 (not shown), the section 11b is lowered into the larger part of the opening on one side of the wall and the necessary electrical and burnerfuel supply connections are made. This section is then pushed to one end of the opening and the exhaust gas connection 21a is connected to a flue. The remaining section 11a is then lowered into position and electrical connection is made with the blower motor 109. The sections are connected together at their adjacent edges by detachable clips 129 (Fig. 3, not shown), and finally the grille is placed in position over the sections.

Title: Twinplex telegraph transmission
IPC: H04L5/08
Filed: 1961-01-27
Abstract: 966,109. Twinplex systems. STANDARD TELEPHONES & CABLES Ltd. Jan. 27, 1961 [Jan. 28, 1960], No. 3262/61. Heading H4L. In a receiver for a twinplex system in which the different combinations of mark and space on two channels are represented by four frequencies, the frequencies are doubled before being filtered and utilized. This enables closer spacing of the frequencies without imposing more stringent requirements on the receiver. As shown, the frequencies in question are 975, 1175, 1375, 1575 c/s. respectively and these are fed via the band-pass filter 22 to an amplitude limiter 23 whose output is applied to an integrating circuit 36, 37 to produce a triangular waveform rich in second harmonics. Filters 43, 42, 41 tuned to the second harmonics of the first three of the frequencies feed diodes 28, 29, 30 whose outputs operate keyers 31A, 31B in appropriate combinations to apply mark signals to tone keyers 32, 33 of the two channels A, B. The fourth frequency corresponding to space or both channels is not used here, but may be used to inhibit the harmonic generator. The transmitter, Fig. 1 (not shown), may be of the type in which the signals from two channels operate keying devices operating on respective voltage sources, to produce across a resistor four discrete voltages corresponding to the different combinations. These operate to frequency shift the transmitted carrier accordingly.

Abstract: 1,025,396. Exchange equipment. AUTOMATIC ELECTRIC LABORATORIES Inc. Jan. 28, 1963 [Oct. 26, 1962], No. 3516/63. Heading H4K. Alternating ringing potential from generator RG is applied to the line A through one winding 2 of a reed-capsule type relay RT1, which due to the balancing m.m.f. induced in the oppositely wound winding 3 by transformer TW remains unoperated until the removal of a subscriber's handset changes contact 14 and completes D.C. path through winding 2 to unbalance and operate the relay and thereby remove the ringing potential from the line. Relay RT2 by opening contacts 10-11 and closing 18-19 connects the ringing potential to the line and disconnects it as this relay is shorted by contact 21 of operating reed relay RT1. Winding 3 of the reed relay is shorted and inductively coupled to the other windings to give the relay a slow-to-operate characteristic. All three windings are mounted on an electrically insulating member (Fig. 3, not shown) containing the magnetic core: the flux being concentrated on to the reed capsules by the L-shaped end-plates.

Title: Improvements in or relating to the preparation of isonicotinic acid hydrazide
IPC: C07D213/86
Filed: 1957-02-01
Abstract: Isonicotinic acid hydrazide is prepared by the elimination of water from the hydrazonium salt of isonicotinic acid, or from a mixture of isonicotinic acid and hydrazine in which the said salt is formed in a solution but from which it has not been isolated, by heating said salt, or the solution thereof, in the presence of a solvent (defined as an organic liquid which keeps the hydrazonium salt of isonicotinic acid in solution) and a diluent (defined as an organic liquid other than a solvent which acts as a water entraining agent under the conditions of the reaction) to a temperature at which distillation occurs.  One or more solvents and/or one or more diluents may be employed, specified solvents being n-butanol, n-amyl alcohol and ethanol, and specified diluents being toluene, xylene and benzene.  A mixture of isonicotinic acid and hydrazine hydrate with the solvent and the diluent is preferably subjected to gradual distillation under reflux and the mixture of solvent and diluent from the distillate continuously or periodically led back to the reaction mixture during the course of the reaction, or is heated to 110 DEG  to 170 DEG  for a period of 10 to 30 hours and the solvent, diluent and water removed during and/or after the completion of the reaction by distillation. The isonicotinic acid hydrazide prepared as above is identified by conversion to the corresponding isonicotinyl hydrazone by reaction with benzaldehyde.  The hydrazonium salt of isonicotinic acid is prepared by addition of hydrazine hydrate to an ethanol solution of isonicotinic acid followed by distillation to remove the ethanol.

Title: Improvements in Method of and Means for Measuring Weights.
Inventor: ANTRIM LOUIS CLAUDE
IPC: G01G19/00
Filed: 1919-02-14
Abstract: 123,730. Antrim, L. C. Feb. 14, 1918, [Convention date]. Computing-apparatus. - A weighing-scale for counting the number of units contained in bulk is provided with a number of arc-shaped indicating cards 20, Fig. 3, and a " key "scale 6, Fig. 1, the latter for measuring the displacement of the scale mechanism (of any convenient construction) caused by a single unit, or a fraction or a multiple thereof. This displacement is indicated by the hairline 33 of a pointer 2, and is read from the " key " scale 6 as a number corresponding to one of the cards 20. The " key " scale, Fig. 1<a>, is provided at one side with a column of consecutive numbers, and is graduated from a vertical zero line 31 with a series of graduations of increasing size, the coincidence of the hair line 33 with a particular graduation determining the card 20 to be used. The selected card is moved to the front and the articles in bulk are placed on the machine, the number of articles being indicated on the selected card by a pointer 3. Each card 20 has a series of arcshaped scales for use according as a single unit, or a fraction, or a multiple was used in determining which card 20 was to be used. When using any particular card, those arc-shaped scales not in use are covered by hand-operated slides 40. In order to allow for the tare, the cards 20 are carried in a holder 13, Fig. 3, which may be moved circumferentially, so that, after placing the tare on the weighing-scale, the holder may be adjusted until the zero on the selected card coincides with the pointer 3. A scale 5 indicates the total weight, in each instance.

Title: Slip Ring Short-circuiting and Brush Contact Releasing Gear.
IPC: H02K17/22
Filed: 1918-03-02
Abstract: 118,797. Phoenix Dynamo Manufacturing Co., and Bennett, A. H. March 2, 1918. Alternating-current motors; brush-holders.-In a slip-ring short-circuiting device and brush-releasing gear for induction motors, the shaft 7 of the operating-handle 6 carries an eccentricallymounted roller 8 which is situated in a groove in the axially-movable short-circuiting sleeve 1. The sleeve carries three contact sockets 2 into which there may enter studs 17 attached to the sliprings 3, 4, 5. The handle 6 is arranged to turn through an angle slightly beyond 180 degrees, so that the roller may remain clear of the sides in its end positions, the motion being limited by a stop 9 and a ball plunger 10. The brushes are released from the slip-rings after the short-circuiting has been completed by the use of a slotted link 11 and a pin 12 on the shaft 7. The pin bears upon one end of the slot and, in its travel, draws the link over and moves a lever 13 and a pivoted member 14, which bears down upon brushholder pawls 15, thereby releasing the brushes from spring pressure.
Patent GB-929857-A (GB)
Title: Improvements in or relating to indicating systems
IPC: H02H3/04
Filed: 1962-02-01
Abstract: 929,857. Protective arrangements. BROOKHIRST IGRANIC Ltd. Feb. 1, 1962 [March 28, 1961], No. 3821/62. Class 38 (5). [Also in Group XL (c)] In an indicating system for showing when a set of contacts, e.g. of an overload relay among a plurality of such sets are opened, a circuit is connected across each set and includes a transistor. having its operating potentials supplied from an A.C. supply through a transformer and an indicating device connected in its emitter-collector circuit. In the system of Fig. 1, when the contacts OL1 are closed, the transistor T1 is non-conducting as the bias potential derived from the secondary winding S1 of a transformer TR1 exceeds that from secondary winding S2. When the contacts OL1 are opened, the base of the transistor T1 is no longer biased by winding S1 and the transistor conducts to energize the operating coil OC of a flag indicator F1. When the fault condition has been corrected and the contacts OL1 have reclosed, the flag indicator F1 is reset by actuating a retractive changeover switch RS1 to energize a resetting coil RC of the indicator. In the arrangement of Fig. 3, under normal conditions when the contacts OL1 are closed, a circuit is completed from a secondary winding S5 through the emittercollector circuit of a transistor T2 and contacts OL1 to an indicating lamp ON. The transistor T2 is in its conducting state and the lamp ON is lit. The hot filament of the lamp presents a high resistance to the emitter-base circuit of a further transistor T3 and the voltage drop across the filament renders this transistor non- conductive or substantially non-conductive so that a lamp OFF is not lit or only gives a faint glow. When the contacts OL1 open, the circuit for the lamp ON is opened to extinguish the lamp and stop the transistor T2 conducting. The bias voltage applied from lamp ON to transistor T3 is removed so that transistor T3 conducts and energizes lamp OFF. The voltage drop across this lamp now biases the transistor T2 so that it cannot conduct and automatically restore the system when the contacts OL1 reclose. On the operation of a resetting switch RS2, the opening of contacts 1 deenergizes the transistor T3 and so permits the transistor T2 to become conducting. A flag indicator Fl is operated when contacts OL1 open, by the charging current which flows through the indicator operating coil OC to a capacitor Cl. This indicator is reset when its resetting coil RC is energized on the closing of contacts 2 of the resetting switch RS2. The capacitor C1 when charged prevents the operation of any other flag indicator should a further fault condition cause the opening of contacts such as OL2, so that only the first fault condition is indicated by a flag indication. The slight delay provided by a relay VR ensures correct operation when the system is first switched on and the thermal delay of the lamps causes the correct transistor to conduct after each negative half-cycle.

Abstract: 123,421. Jeans, A. E., and Hayes, P. T. March 6, 1918. Metal-pots for type-bar-making machines. In an apparatus for automatically supplying metal to the melting-pot 11, used type-bars 4 are stored in a magazine 1 and at each casting-operation are delivered one or more at a. time to a shoot 10 leading to the melting-pot, by a cam-operated slide 7 arranged at the bottom of the magazine.; an alarm for indicating that the magazine is nearly empty may be provided. The slide may be formed with steps 8, 8<x>, the steps 8 being normally within the magazine. When the slide is moved outwards, the bottom type-bar is carried through a slot 9 and the pile then rests on the step 8<x>. On return of the slide the type-bar on the step 8 is removed by engagement with the bottom type-bar in the pile. The step 8<x> is preferably detachable so that steps of different thicknesses may 'be employed for the purpose of ejecting more than one type-bar. In modifications, the slide is formed with a single step and a detent is provided for holding back the type-bar or type-bars when the slide returns; or, the slide may be formed with a through hole to receive the bottom type-bar, which is delivered when the hole comes above the shoot. The slide may be actuated by a rotary cam 14 and be returned by springs 17; or, a sliding wedge which abuts on a fixed surface and on the slide may be provided. The alarm consists of an electric bell 18 in circuit with contacts 19 which are bridged by a spring 21 when the type-bars permit the spring to pass through a slot in the magazine. The spring may have a cross-strip for engaging the outer ends of the contacts; or, as shown, the spring may have a tapered end arranged between tapered parts of the contacts.
