Title: Improvements in or relating to television and like apparatus
IPC: H04N3/12
Filed: 1930-07-30
Abstract: 359,981. Television. BAIRD, J. L. and TELEVISION, Ltd., 133, Long Acre, London. July 30. 1930, No. 23010. [Class 40 (iii).] For colour television in a system employing a receiver constituted by a bank of lamps of the type described in Specifications 222,604 and 291,121, [both in Class 40 (iii), Telegraphs, Electric], each single lamp is replaced by a set of filament lamps each of which emits light of a different colour. Transmitter. Light from a source 14 passes through apertures arranged in three contiguous spirals 11, 12, 13 on a disc 10, and is reflected from the object 15 to light-sensitive cells 16 arranged in a bank. The spirals 11, 12, 13 are covered with strips 17, 18, 19 of translucent material of different colours, e.g. red, green and blue, so that the object is successively scanned by beams of these colours. Receiver. The receiving screen is formed by sets of three lamps 24, 25, 26, each set being arranged in a cubicle formed by intersecting opaque partitions 22, 23. Corresponding lamps of the sets have their bulbs of glass of the same colour, and each set has bulbs of the three colours according to those employed at the transmitter. Each lamp of the set may be enclosed in a cubicle, and a translucent diffusing screen 27 is placed in front of the lamp bank. The signals from a receiving amplifier 37 are distributed to the appropriate lamps as illustrated diagrammatically in Fig. 3, by the cooperation of a switch arm 32 moving over segments 31 with an auxiliary selector switch 36 rotated over segments 33, 34, 35. Each segment 31 is connected to terminals of a set 30 of the lamps, whilst the segments 33, 34, 35 are individually connected to all lamps appropriate to a particular colour. The arm 32 is rotated three times as rapidly as the arm 36, and during each rotation effects the illumination of all the lamps of one of the three colours. In an alternative method, the arm 36 makes one revolution whilst the arm 32 contacts with a segment 31. In this case the lamps of each set are illuminated in succession, and the sets of lamps are successively actuated. The switching devices employed may be of the type illustrated in Figs. 1 and 2 of Specification 347,741. Synchronism and phase adjustment of the receiving system may be effected by the means described in Specifications 320,639 or 336,655, [both in Class 40 (iii), Telegraphs, Electric]. The signals may be sent over a number of separate channels and applied simultaneously to the lamps of a set, the selector device 33 .. 36 being unnecessary in this case. At the transmitting station the object may be Bood-lighted and explored in the manner described in Specification 283,957, [Class 40 (iii), Telegraphs, Electric]. Specifications 347,254 and 348,211 are also referred to.

Filed: 1939-08-10
Abstract: 533,310. Two-part couplings. ROTAX, Ltd., and ALLEN, A. MASSEY-. Aug. 10, 1939, Nos. 23088 and 27659. [Class 38 (i)] The contacts h of multiple plug and socket couplings, terminal pillars &c. are located in holes s in a body a and locked therein by a plate j having holes r displaced from the holes s so that the edges of the holes r engage grooves q or reduced portions of the contacts The holes r, s may be displaced in the same direction so that the locking engagement is effected by a lateral rotary movement of the plate j relative to the body g or the displacement may be in various directions so that assembly is effected by first engaging the contacts with the plate j and then inserting them in the holes in the body g. This operation can be facilitated by a jig consisting of a set of flexible pins mounted in a base, the pins being inserted through the holes in the body g into the contacts which are previously inserted in the plate j. Another form of jig for use with contacts arranged in straight lines consists of plates v, Fig. 10, notched at x. to hold the contacts and mounted to turn on pivots in a support w. The jig being inserted between the contacts with the plates v at right angles to the position shown, when the plates are turned they move the contacts into position for insertion in the body g.

Abstract: 616,889. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 2, 1946, .No. 23142. Convention date, Oct. 30, 1941. [Class 39 (i)] [Also in Group XL (c)] An ultra-short-wave oscillator comprises a valve with pairs of lead-ins connected to the cathode, anode and grid electrodes, the lead-ins being arranged symmetrically around the centre of the valve and forming part of a fourconductor transmission line which is tuned by four other conductors sliding inside them and connected together by a common rigid spacer member, the capacitance and inductance per unit length of the lead-ins and transmission line being made substantially equal. Fig. 3 shows the conductors 28, 29, 30 and 31 of a transmission line connected to the lead-ins of the valve 41 and tuned by the members 32, 33, 34 and 35 connected to the common insulated spacer 36 adjusted by screw 54. Fig. 8 shows schematically the connections to the valve electrodes, the cathode being balanced with respect to earth by inductor 58 and capacitor 59. The positive H.T. supply is connected to the valve anode at the voltage node point 60 and the grid leak 61 is connected to the grid at voltage node point 62. The valve is designed to use a conventional octal base. Figs. 4, 5 show how the symmetry of the electrode connections is obtained by mounting them in a plane parallel to the base of the valve. The electrodes are spaced apart and supported by two end mica plates 66, 67 held in place by turned-over lugs 68 on the anode, the electrodes being connected by short metal straps to the corresponding valve pins. The constants per unit length of the transmission line and the valve lead-ins are made substantially equal by maintaining the same spacing between the four parts of the transmission line and the four lead-ins connected to the grid and anode electrodes, Fig. 6 (not shown).

Title: Improvements in or relating to the manufacture of titanium
Inventor: QUIN JAMES PATERSON
IPC: C22B34/12
Filed: 1955-08-11
Abstract: Titanium of low hydrogen content is obtained by reacting titanium tetrachloride with sodium in an inert (e.g. argon) atmosphere and in the presence of lower chlorides of titanium and leaching the products with an aqueous solution of a mineral acid containing a soluble phosphite, preferably an alkali metal phosphite.  The presence of the lower (or sub-) chlorides is ensured by using an excess of the tetrachloride amounting to more than 0.25 per cent and preferably from 0.5 to 3.0 per cent by weight of the stoichiometric quantity. The acid solution should contain less than 10 per cent sodium phosphite, preferably between 0.5 and 2 per cent by weight; a preferred solution contains 2 per cent hydrogen chloride and 1 per cent sodium phosphite.  In an example molten sodium was reacted at 850 DEG C. in argon with 0.8 per cent excess titanium tetrachloride, cooled in the argon, ground to powder, and leached twice at room temperature with the above preferred solution.  The hydrogen content of the titanium was 0.003 per cent.  Specification 788,308 is referred to.

Abstract: 1,194,480. Transistor amplifier circuits; generating electrical oscillations. TEKTRONIX Inc. 16 May, 1968 [24 May, 1967], No. 23212/68. Headings H3B and H3T. [Also in Division G1] Amplifier circuit.-In a linear direct current amplifier the input is applied between the bases of two transistors 54, 56 whose emitters are connected together through a gain control resistor 58 and whose collectors are connected to the emitter and base, respectively, of a transistor 60. Positive voltages appearing at the collector of transistor 60 are then amplified by a double emitter follower circuit comprising transistors 62 and 72 and negative voltages by a similar circuit comprising transistors 64, 78. The output terminal 80 is connected through resistance 82, inductance 84 and thermal stabilizing resistances 74, 76 to the emitters of transistors 72, 78. The resistance 82 provides a z 0  termination for a coaxial line connectible to terminal 80, and inductance 84 provides additional output drive at low frequencies. An R.C. network 86, 87 compensates for the inductive effects of transistors 72, 78. Transistors 62, 64 are connected to their respective power supplies through current source transistors 68, 70. To prevent a surge of current in a winding 26<SP>1</SP> when a switch contact 83 is moved from a terminal 98 to its normal position on amplifier output terminal 80, a capacitor 146 is charged whilst contact 83 is on terminal 98 to establish heavy conduction through transistor 66 and diode 154. On return of contact 83 to terminal 80 this transistor continues to conduct until the capacitor has discharged, and during this time holds the bases of transistors 62, 64 to earth potential. Oscillator circuit.-To produce a decaying oscillation 139 a capacitor 138 is first charged and then connected to an oscillator circuit to provide the latter with a decaying supply voltage. The oscillator circuit comprises crosscoupled transistors 104, 106 and a tuned circuit formed by capacitor 102 and a winding 26<SP>1</SP> on a magnetic core 12<SP>1</SP>. The embodiment described provides oscillations of 10-15 kHz, decaying in about 0À1 seconds, for demagnetizing the core 12<SP>1</SP>.

Title: Apparatus for removing clinker from the heating surfaces of boilers and the like
IPC: F28G11/00
Filed: 1928-08-13
Abstract: 322,162. Hertig, E. Aug. 13, 1928. Cleaning.-Clinker is removed from the heating surfaces of boilers &c. by the flame from a burner nozzle 14 which is supplied with oxygen and oil fuel by pipes 11, 12 and is surrounded by a sleeve 15 lined with refractory material. The fuel mixture is ignited initially by the flame from an asbestos wick saturated with naphtha, inserted in the annular space between the burner nozzle and the refractory lining. The refractory lining serves to radiate heat to the burner nozzle to heat the fuel mixture before discharge. The fuel reservoir 6 is fitted with a hand pump 8 and is also connected to the oxygen supply pipe by a valve-controlled pipe 10 so that the pressure of the oxygen can be utilized for forcing the fuel to the burner nozzle. In another form of burner the fuel is heated by passage through a tube coiled around the burner head before mixing with the oxygen.

Abstract: 999,856. Electromagnetic relays. GENERAL ELECTRIC CO. June 19, 1962 [July 3, 1961], No. 23499/62. Heading H2B. In a relay comprising a housing, an axially movable metallic sleeve 55, an armature 57 slidable on said sleeve and arranged to move it between two positions, a cap 65 secured around said sleeve and a spring 69 mounted between the armature and cap, the sleeve is split axially to reduce eddy currents. The sleeve is preferably of brass and carries a contact bridge 59 at one end which co-operates with fixed contacts 77. The operating characteristics of the relay are set during manufacture by suitably positioning the cap on the sleeve where it is held by the resilience of the sleeve. The housing comprises three interfitting parts 5, 7, 9 which are held together by means of a pin 13 which passes through them and a spring fastener 21. The housing has a plurality of projections 107, 109 which co-operate with slots 103, 105 in a mounting frame 95 so that the relay may be mounted in many orientations. When the relay is energized armature 57 moves upwards, compressing spring 69, thereby urging sleeve 55 and contact bridge 59 upwards. On de-energization, the armature strikes the contact bridge a hammer-blow and so breaks any weld which may have been formed.

Abstract: 1503713 Fusible cut-outs McGRAWEDISON CO 30 May 1975 [28 June 1974] 23662/75 Heading H2G An electric fuse 10 comprises a high thermal conductivity ceramic housing 12 with an elongate passage 18 therein containing a constricted (at 40) fusible element 20 of silver, copper or other high melting point metal and a sand filler 45, the fusible element being fusible by a sudden heavy overload or by a sustained low overload. On passage of the rated current, the constriction 40 is heated nearly to its melting point, excess heat being carried away via the sand filler, the ceramic housing and a cooling medium, which may be blown air, surrounding the housing. The constriction is positioned closer to the inner surface of the housing than to the end cap 44 aiding removal of most of the heat through the body of the fuse and preventing a rise in temperature at the terminals sufficient to melt the soldered connections of the fusible element with the cap 44 or of the cap with the terminal lug 56. Fuses may have three passages in the housing with fusible elements inserted in one, two or all three passages as required giving three different current rating fuses from a common set of components. Two or three such three-passage housings may also be bound in parallel by suitably shaped end caps for further ranges of current rating. The fusible element may have a number of constrictions along its length each of which may blow thus reducing the possibility of arcing subsequent to a heavy overload.
