Title: Deflection yoke for a triad-type colour cathode ray tube
IPC: H04N9/285
Filed: 1970-07-15
Abstract: 1324412 Electron beam magnetic deflection apparatus GTE SYLVANIA Inc 15 July 1970 [15 July 1969 (2)] 34407/70 Heading H1D A deflection yoke for a colour television tube employing three guns in delta formation, comprises first and second horizontal deflection windings 19 and 21 (shown by blackened dots in Fig. 2) oppositely wound so that they are in mirror image relationship and first and second vertical deflection windings 31 and 33 (shown by open dots) toroidally wound on a common core (not shown), and may include flux correction means so that both the red and the green rasters are the same pin-cushion shape (Fig. 7, not shown), which distortion is corrected in known manner. In Fig. 2 the flux correction means comprises the winding gaps 23 and 25 for the horizontal coils and the gaps 35 and 37 for the vertical coils, but short-circuited turns or shielded turns may be used as an alternative; in addition the horizontal windings may include added turns 27-30 disposed on opposite sides of the gaps to enhance electron beam convergence. The coils may be bank wound, as shown, with each turn of a second layer supported by two turns of a first layer, and the vertical coils are interleaved with the horizontal coils; the vertical coils may be connected in sawtooth manner, i.e., the first layer of turns of the total winding are connected in series and wound in one direction, and the second layer is wound in the same direction with its beginning connected to the end of the first layer so that the potential difference between turns of the two layers is more nearly constant. The coils may be identical in the four quadrants, or as illustrated the added turns 27, 28 may differ slightly from turns 29, 30 to compensate for the earth's magnetic field. Curves and equations for the winding distribution are given (Figs. 8-10, not shown).

Title: Process for the preparation of new soluble aromatic amino compounds of therapeutic value
IPC: C07C311/37
Filed: 1936-12-15
Abstract: Sulphonamides of therapeutic value are prepared by treating p-aminobenzene-sulphonamide with aliphatic unsaturated aldehydes, aromatic aldehydes, or aryl-aliphatic aldehydes which are saturated or unsaturated in the aliphatic side chain, in the presence of an alkali metal bisulphite.  When the aldehydes are saturated, the three reactants are employed in equimolecular proportions, but when the aldehydes are unsaturated an additional molecular proportion of bisulphite is necessary for each double bond.  The products, which contain sulphonic acid groups in the aldehyde residue attached to the nuclear amino group, are water-soluble.  The process may be varied by reacting the sulphonamide with bisulphite compounds of the aldehydes, or by treating with bisulphite the condensation products of the sulphonamide and aldehyde.  Examples are given of the preparation of (1) sodium p-benzylaminobenzene-sulphonamide-o -sulphonate from benzaldehyde, p-aminobenzene-sulphonamide and sodium bisulphite, or from benzaldehyde-sodium bisulphite and p-aminobenzene-sulphonamide, or benzylidene-amino-benzene-sulphonamide (prepared by condensing benzaldehyde with the sulphonamide) and sodium bisulphite, in each case using equimolecular proportions; (2) sodium p-(b -phenylethylamino) - benzene - sulphonamide - a  - sulphonate from phenylacetaldehyde, p-aminobenzene-sulphonamide and sodium bisulphite in equimolecular proportions; (3) sodium p-(g -phenylpropylamino) - benzene - sulphonamide - a  : g -disulphonate from sodium bisulphite, cinnamic aldehyde and p-aminobenzene-sulphonamide in the molecular proportions of 2 : 1 : 1; the Schiff's base prepared from the aldehyde and sulphonamide or the bisulphite compound of the aldehyde may also be used, and in place of cinnamic aldehyde, acrylic or crotonic aldehyde may be employed.  Specifications 462,765 and 470,462 are referred to. The Provisional Specification also describes the use of nuclear-substituted derivatives of the sulphonamide.

Title: Improvements in oscillator circuits for superheterodyne receivers
IPC: H03J3/28
Filed: 1933-12-07
Abstract: 424,714. Valve circuits for wireless reception. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Dec. 7, 1933, No. 34460. Convention date, Jan. 2. [Class 40 (v)] To improve the constancy of the difference between the natural frequencies of the receiving circuit and the oscillator circuit with different settings of the common tuning knob of a superheterodyne receiver, resistance is added to the tuned oscillator circuit in various ways. As shown in Fig. 4 the resistance is connected across the padding condenser C2. In a modification it is arranged in series with C3 and in a further modification a resistance in series with a condenser is connected across the whole inductance of the circuit. Fig. 9 shows an arrangement in which the tuned circuit is shunted by a resistance R3 in series with a further tuned circuit which is heavily damped and the natural frequency of which is equal to that of the middle frequency of the receiver circuit tuning range. In addition the condenser 2 may be shunted by a resistance and a further resistance may be arranged in series with C3. In further arrangements the tuned circuit is shunted by a resistance and inductance in series or a part of the tuning inductance is shunted by a resistance. As shown in Fig. 13 a resistance in series with the tuning inductance is shunted by a condenser in series with an inductance and resistance in parallel. In all cases an inductance and resistance in series may be replaced by a high-resistance inductance.

Title: Improved coupling circuit for alternating current networks
Inventor: THANAWALA HEMESH LAXMIDAS
IPC: H02H9/02
Filed: 1968-07-19
Abstract: 1,218,585. Coupling A.C. networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 4 July, 1969 [19 July, 1968], No. 34572/68. Heading H2H. Two A.C.-networks, which may be generating or consuming, are connected by an LC series resonant link. Excessive current in the link increases its impedance due to two parallel branches, each including an A.C. saturable reactor, connected across the capacitor. In the embodiment shown, the reactor L2 saturates first, effectively connecting resistor R3 across the capacitor XC. A further increase in voltage causes the reactor L4 to saturate connecting resistor R4 across the capacitor. The resistors serve to damp undesirable oscillations, and also provide an in-phase load which prevents power factor loss and tends to keep synchronous machines in step. The resistors may be variable and may be connected to electronic switches.

Title: Improvements in machines for reading in and punching jacquard cards
IPC: D03C17/00
Filed: 1947-12-30
Abstract: 673,928. Punching jacquard cards. VELGH E. A. Dec. 30, 1947 [May 11, 1946; May 10. 1947], Nos. 34672/47 and 34673/47. Class 142(i) A reading in and punching machine comprises a row of punches 1 moved one at a time by a lever 5 moved by a pin 6 engaging, grooves in a cam 7, the lever being locked or returned before punching occurs if a hole is not to be punched. When a needle 46, following a design 45, indicates a new weave, a lever 42 is manually depressed and the appropriate band 9 is brought into use. The band corresponding to the previous weave then returns to neutral. The punches are moved by pegs 21 arranged in a helix on a rotating drum 20 to bring a lug 24 into engagement with a a groove 23 in a beam 22 moved downwards by the lever 5 through connections 25. When a peg in the band 9 indicates that a hole is not required a feeler 40 rocks a shaft 43 and a lever 39 engages the lever 5 causing the pin 6 to enter a return groove 15 with out lowering the punch sufficiently to punch the card. Each band 9 has a longitudinal row of holes for each pick of that particular weave. Movement of the lever 5 also causes movement of the needle 46 over the design, rotates a ratchet 37 to advance the bands 9, and moves a card holder 2 through a ratchet 27. Lacing holes, cut by manually operated punches 32, locate the card in the holder. The punches are set at an angle to the card. A punched card can be duplicated by laying it on a blank card in the holder and putting the needle card design and the bands 9 out of action. If a descending punch then feels a solid part of the card to be copied, the pin 6 follows a return groove 14 without causing punching. A hole not to be copied is filled with a block, and a descending punch, feeling this block, forces the pin to enter another return groove 13.

[Class 106 (iii).] In apparatus as described in Specification 220,601, [Class 106 (iii)], in which the average speed during a time interval is measured directly, an independent source of power, such as an electric motor, drives both the distance and time elements, while the distance element is synchronized with the shaft, the speed of which is required by remote electric control. In the earlier Specification, a shaft 7 rotated in accordance with distance from the shaft 1, drives a toothed wheel 7<11> by a pinion 8 during a given time interval, and thus rotates a wheel 7<111> against a spring 34, the wheel 7<111> actuating an indicator, not shown. At the end of the time interval, a cam 5 rocks the shaft 7 and disconnects the gears 8, 711, the wheels 7<11>, 7<111> being retained by spring pawls 30, 31 until release by cams 32, 33. The cams are carried on a shaft 6 rotated by gearing including a slipping member from the shaft 1, the speed being controlled by an escapement 21, 18. The cam 5 on shaft 6 engages and disengages the gears 8, 7<11> by means of the rocking lever 41. According to the invention, the shaft 1 is driven by an independent motor which drives both the distance and time shafts 7, 6, the distance shaft 7 being synchronized with the shaft, not shown, the speed of which is required. The shaft 7 is driven from the toothed wheel 3 through a light friction clutch 7<1>, the escapement wheel 4, a spring 9 and flywheel 10. The speed of the escapement wheel 4 is regulated by a rocking element 11 actuated by electromagnets 12, 13, Fig. 2, energized by intermittent currents supplied from an interrupter, not shown, on the shaft whose speed is required. Slipping of the clutch 7<1> allows this synchronization. Alternatively, the shaft 7 may be actuated by a small synchronous motor supplied with current from an alternator.

Fig. 2 shows part of the peripheral portion of a flat canopy 21, to which are attached by folded, webbing reinforced seams 23, a series of net panels 22, each extending between two adjacent rigging lines 26. Each rigging line has the edges of the adjacent panels wound round it, and is covered by webbing 25. A tape 30 extends around each rigging line, and is stitched to a webbing reinforced hem 24 on the panels 22. Cross stitching 29 secures the rigging lines to webbing 25 and tapes 30. The circumferential length of hem 24 may be approximately equal to, or less than that of seam 23, and each panel 22 may taper in the direction away from the crown. The canopy gores and panels 22 may be cut on the bias. Fig. 3 shows a further flat canopy in which each gore is composed of panels 31, 32 and a small panel 33, the canopy proper thus having a sawtooth shaped periphery. The net panels 34 are shaped to correspond. Fig. 5 is a cross-section of a further canopy periphery. The skirt is formed from two panels of net 51, 52 stitched to the canopy 53 and to a webbing reinforcement 54. The two panels are also seamed and stitched to two wide webbing tapes 55, 56, and the depths of the panels are such that during deployment, the tapes 55, 56 assume a tilted position as shown, and possess axodynamic properties assisting correct inflation. The material of one panel may stretch more readily than that of the other, at least in the direction of the crown.
