IPC: H04N1/50
Filed: 1928-07-11
Abstract: 322,822. Baird, J. L., and Television, Ltd. July 11, 1928. Divided on 321,441. Television.-In order to obtain a relatively large image in a television receiver, a plurality of lamps are mounted on two or more spirals on a disc, cylinder, or cone, rotated at a speed equal to or a, multiple of that of the transmitting exploring device. In one modification, Fig. 1, a double spiral of lamps 28 are attached to a disc 26 which rotates at double the speed of the transmitting disc, and by means of pulleys 50,. 52 and belt 48 at double the speed of a twosegment commutator 46 and slip rings 42, 44 on a shaft 45. The outer spiral of lamps has a common lead 36 connected to a slip ring 32, the inner having a common lead 38 connected to a slip ring 30, while the pairs of lamps on a common radius have their free electrodes attached to the same segment of a commutator 34. The slip rings 42, 44, on the half speed shaft 45, are joined to the two segments respectively of the commutor 46 on that shaft, and also to the two slip rings 30, 32 on the shaft 25 through appropriate brushes. The receiver is fed with modulated current through leads 58, 62 connected to brushes 60, 64 respectively bearing on commutators 46, 34 respectively. It will be seen that the commutator 46 feeds the outer spiral and the inner spiral of lamps successively by connecting the common leads 36, 38 in turn to the lead 58, while the other input lead 62 is connected to the appropriate lamp by the commutator 34. As an alternative the spiral of lamps may be replaced by a spiral container 66,. Fig. 2, with multiple pairs of electrodes 72, 68.

Abstract: 624,700. Indicating-apparatus. PHILIPS LAMPS, Ltd. May 17, 1946, No. 14970. Convention date, Feb. 24, 1942. [Class 106 (iv)] [Also in Group XL (c)] In an indicating system, particularly for a radio receiver, a pointer or cursor moves along the surface of a pivotably mounted oblong scale, one edge of which forms a running surface for a guide shoe rigidly attached to the pointer. Fig. 2 shows an arrangement in which a cursor 5 is moved along a scale 1, pivotally mounted on the top of a radio receiver cabinet 52, by the movement of a cord 12 which is attached to a shoe 45 running on a guide 31. The shoe 45 has an arm 51 which extends through the top of the cabinet and is coupled to the cursor by a pin 47, to which it is hinged at 46. Pin 47 passes freely through a hole in plate 48 attached to the cursor so that the scale, and hence the cursor, can pivot freely, a spring 50 being provided to urge the lower half of the cursor into engagement with the lower edge of the scale. In a modification, Fig. 1 (not shown), the axis of the hinge 46 is made to coincide with the axis about which the scale pivots so that the hinge can be directly attached to the cursor. The scale may be illuminated by the internal reflection of light from lamps arranged concentrically with the pivots. In the Specification as open to inspection under Sect. 91, Fig. 5 (Cancelled), shows an arrangement in which cursor 25 is moved along scale 1, pivotably mounted at A and B, by cord 12 which passes through holes 19 and 20 into the cabinet of the set on which the scale is mounted. This arrangement may be modified by providing a longitudinally slotted tube between A and B, the cord passing through the tube and being attached to a bush, which slides on the tube and is attached to the pointer (as in Fig. 4 (Cancelled) and not shown). In a further arrangement, Fig. 2 (Cancelled), a curved member 81 projects through the slot 82 in the cabinet top to engage a member 71, which runs on rod 31, for all inclinations of the scale. This subject-matter does not appear in the Specification as accepted.

Abstract: 877,116. Tube walls for furnaces. BABCOCK & WILCOX Ltd. April 29, 1960 [May 1, 1959], No. 15044/59. Class 51 (1). Horizontal tubes lining the walls of a boiler furnace are connected in parallel and arranged so that each of the parallel circuits receives approximately the same heat input and are supported by vertical members which are heated during operation to reduce differential vertical expansion. Wall tubes 23 connected in pairs to rods 25, Figs. 4, 5 are supported from slots 21 in vertical members 20 within the furnace insulation 47. The members 20 are supported by lugs 30 from vertical stays 28, which are supported from horizontal back-stays 43 so as to allow for differential horizontal expansion. The furnace wall is sealed by plates 39, strips 41, 42 sealing the horizontal gaps between plates 39 and the gaps between the plates 39 and supports 20 respectively, while allowing expansion. The support members 20 may be replaced by angle members 52, 53 welded to vertical tubes 51 connected in the boiler circulation, Figs. 7, 8. The furnace wall is divided into zones, each zone receiving a different heat input, and the tubes of each zone are divided into groups. The tube groups comprise pairs of tubes, each tube pair having adjacent inlet and outlet ends, and the tubes of a pair extending in opposite directions round the furnace walls. The adjacent inlet ends of pair of tubes are connected to tubes 68 leading from a lower zone and adjacent outlet ends of another pair of tubes of the same group are connected to tubes 67 leading to corresponding tubes in an upper zone by bores 70 in a block 69, Figs. 11 and 13, and the tubes 67 form part of the suspension of the tube walls, Fig. 12. The tubes of a group may be crashed sidewardly near their inlet and outlet ends, so that a plate 81, Fig. 16, may be welded between the tubes 84 leading to the upper zones and the tubes 83 leading to the lower zones so that the upright tubes may support the horizontal wall tubes. The furnace may have a lower part lined with vertical tube lengths, and horizontal tube lengths lining the upper region of the furnace may be connected in series by upright tube lengths lining the side walls of a lateral gas pass. The firing zone or the region of the burner ports in the firing zone may be lined with upright tubes.

Title: Quench triggering circuit for an electronic flash photographic system
IPC: H05B41/32
Filed: 1972-04-04
Abstract: 1343563 Electronic flash control circuits HONEYWELL Inc 4 April 1972 [15 April 1971] 15277/72 Heading G2A A flash photographic system has a quench triggering circuit comprising a light integrating circuit R8, C7, a threshold circuit including a reactance C6 which is charged to generate a rising threshold signal, a comparison circuit which generates a quench signal when the signal from the light integrating circuit exceeds the threshold signal, wherein, to prevent the threshold signal falling as the supply voltage falls, the reactance is charged via a non-linear circuit which provides regulated charging and a voltage responsive circuit for reducing the effect of changes in supply voltage on the magnitude of the threshold signal. Switch S1 is closed upon the opening of the camera shutter, and this initiates a flash, Fig.1B. The reflected light is incident upon LASCRI and a current representative of the amount of light flows through its gate terminal to charge C7. Eventually the voltage on C7 exceeds that on C6, the thyristor LASCRI fires, the voltage between terminals 12, 13 drops to near zero and the flash is terminated. Reactance C6 is charged via a transistor Q 3  which is turned on via zener diode ZD3 when the flash is initiated. If supply voltage across terminals 12, 13 decreases then transistor Q 3  will be cut-off, and the voltage on C6 will charge towards the decaying anode voltage of LASCRI, preventing the generation of a false quench trigger signal. The accuracy of the circuit is enhanced by the inclusion of a temperative responsive resistor R9.
