Title: Improvements in reflectors
IPC: F21V7/09
Filed: 1924-03-06
Abstract: 234,905. Allom, G. March 6, 1924. Reflectors.-Reflectors are built up of a series of flat strips or sections curved and joined so that when assembled they have a common focus. The strips or sections are flat in the direction of their width and curved in the direction of their length. When the strips are bent in the form of a parabola, the resultant beam from a, source of light placed at the focus is oval in cross-section. The various sections A B, B C, C D of the reflector are fixed at such angles that they have a common focus, and are bent so that they are in the forms of parabolas along lines L, L<1>, L<2> proceeding parallel to the axis from points on the mirrors situated at the intersection with the section of the lines which bisect the angles which the sections subtend at the focus. In this construction all the rays from the focus are reflected in the same direction and with the same divergence of beam. In a modification the bisecting rays when reflected are not parallel, in which case the divergence is greater than that given by the width of the sections. Reference has been directed by the Comptroller to Specification 156,498,

Title: Improved coin and manually controlled means for the recording and delivery, or multiple production of gramophone or like records
IPC: G11B17/00
Filed: 1929-02-22
Abstract: 333,919. Hordern, H. C. S., Hordern, A. A., and Lynes, B. J. Feb. 22, 1929. Magazine recording and reproducing machines; feed and return mechanism; turntable accessories, -A coin or manually controlled machine which releases a record blank from a magazine, guides it to a turntable for recording, releases it after recording, and delivers it to the operator has its cycle of operations controlled by an electric commutator. The machine may be used for the electrical reproduction of a series of completed records. In the machine shown, the magazine x for blanks is supported over a turntable 3 and has a central guide-rod 52 on which the blanks are threaded. The turntable is driven by a motor (not shown) which can be started by hand or by the insertion of a coin. The drive is connected by spur gearing 4 - - 9 with oppositely rotating screws 32, 33 for propelling the sliding stylus-arm 29 which carries half-muts 30, 31 engaging the screws which are alternately rocked uppermost by a cam 41 operated through a clutch 40 by a solenoid 42. A similar solenoid 39 and clutch 38 operates a T-bar 36, through a cam 37, for raising the stylus-arm. The screws are arranged to give the stylus a slow cutting motion and a quick return. A catch 60 operated by a solenoid 59 releases the stylus-arm so that a weight 57 and cord 56 may bring it to starting position against a stop 58 on the T-bar. The commutator 13, 14, which controls the whole cycle of operations, is driven from the spur wheel 7 by a worm gear 11, 12. The spur wheel 7 also driven, through gears 15 and 16 and a spring-pressed friction clutch y, a crank and connecting-rod 18 vor operating the cams 22, 23 to release the blanks one at a time. For this purpose, isolating wedges 45a, 45<b> and dropping-wedges 46a,46b are driven from the cams 22, 23 by arm 47a, 47b, 48a, 48b. The isolating- wedges support the pile whilst the dropping- wedges release the bottom blank. The gear 16 also drives through a spring-pressed friction clutch z a crank-disc 27 which actuates through a slotted link 28 a rocking arm 24, the end 51 of which is adapted to drive the blanks positively by being pressed through holes in the blanks and against the turntable by the lowering of the swindle 52 when the electromagnet 65 is de-energized. The drive through the friction, clutches y and z is controlled by pivoted detents E, E<1> engaging notches in the driven member, the detents being released to permit the drive by solenoids G, G<1> controlled by the commutator. Secondary commutators 43, 44, fed from the main commutator and driven at a faster speed, control the clutches 38, 40 regulating the stylus feed. To discharge the record, one side thereof is raised by a pin 53 moved upwardly by a solenoid 54.

Title: Improvements in and relating to electron discharge devices and circuits therefor
IPC: H01J43/04
Filed: 1936-02-28
Abstract: 469,488. Electron multipliers; amplifying, generating, and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 28, 1936, Nos. 6099 and 6100. Convention dates, Feb. 28, 1935 and March 30, 1935. [Classes 39 (i) and 40 (v)] In an electron multiplier of the type described in Specification 443,777 in which electrons ejected from a target follow a path mainly clear of that of the incident electrons and fall upon a further electrode at a higher potential than that of the target, and in which electric or magnetic concentrating means concentrate the different beams of electrons, at least two stages of multiplication are used. In addition, a circuit is provided for feeding back energy from a later stage to an earlier one, or one electrode is connected to its potential source through an impedance, such as an inductance, so that the device serves as a modulator or demodulator, or the incident and ejected beams at a target are surrounded by a tubular electrode which extends further along the path of the incident electrons than along that of the ejected electrons and is at a potential positive with respect to the source of the incident electrons. The form shown in Fig. 1, has a photo-electric cathode 3, which may be replaced by an arrangement for introducing electrons into the envelope from an exterior source, a lens constituted by a foraminous cylinder or coating 17, and a coating 19, a target 7, an accelerating screen 21, which may be omitted, a lens constituted by coatings 23 and 25, a second target 15, and a tantalum output electrode 5. The coatings 19 and 25 have short portions 19a, 25a surrounding the ejected electron beams. A thermionic cathode with a control grid may replace the photo-electric cathode as described in Specification 469,477. When the tube is used to give non-linear amplification an impedance is arranged, e.g. in the lead to the target 7. To obtain negative feed-back, the cathode 3 and second target 15, Fig. 4, are coupled through a capacity 33, and resistances, 29, 31 are inserted in their leads. Input is applied to the screen 21a across resistance 35 and the output is taken across resistance 28, and the feed-back ensures that the current density through the screen 21a is independent of light fluctuations. Further amplifying stages may be inserted between the screen 21a and the output electrode 5. Positive feed-back, causing the generation of oscillations may be accomplished in any conventional manner. Modulation may be applied to a target whilst the device is oscillating or whilst the control grid receives a carrier frequency. Magnetic focusing coils may be employed and a Y- shaped tube having a single stage of multiplication and magnetic focusing is described but not claimed. The envelope 1 in Fig. 1, may be cylindrical instead of zigzag. The mode of manufacturing the tube shown in Fig. 1 is described.

Title: Improvements in or relating to a cinematographic projector
IPC: G03B9/10
Filed: 1961-02-20
Abstract: 916,449. Two-speed projectors. PAILLARD S.A. Feb. 20, 1961 [March 2, 1960], No. 6158/61. Class 97 (1). [Also in Group XXXVII] In a projector adapted to be driven by an electric motor at a normal speed or half (or less) the normal speed, some, but less than half, of the shutter blades are withdrawable for normal running but become operative at the slow speed to reduce flicker. As shown in Figs. 2 and 3 fixed blades 12a, 126 and 12c are formed in a disc 11, pressed at its centre into a hub 13. Discs 11<SP>1</SP>, 11<SP>11</SP> are formed, respectively, with blades 12a<SP>1</SP>, 12b<SP>1</SP>, 12c<SP>1</SP> and 12a<SP>11</SP>, 12b<SP>11</SP>, 12c<SP>11</SP> and, when the speed of rotation is low (5 frames per second), are spring-urged by three tension-springs (only two shown) into the position shown to give a total of nine operative blades. When the speed of rotation is increased to 18 frames per second inertia heads 17 move radially outwards in slots 17 and by means of links 21<SP>1</SP>, 21<SP>11</SP> cause rotation of discs 11<SP>1</SP> and 11<SP>11</SP> to bring their blades behind the three of disc 11; there are thus only three operative blades. In another embodiment using inertia heads, these are carried on pivoted levers the other arms of which carry blades, there being an assembly of three such pivoted blades on either side of a disc having three fixed blades. As shown in Fig. 9, disc 41 has three fixed blades, and discs 42 and 43 engage discs 41 and 42, respectively, by pins 46 and 44 extending through slots in the discs. At a slow speed the discs are held, by frictional linings 53, 54, as in Fig. 8, as an auxiliary motor 51 drives discs 42 and 43, via pulley 48, clockwise at a speed slightly higher than that of the main driving- shaft 27. For the normal frame speed, motor 51 drives pulley 48 slower than shaft 27 and the pins are held against the other ends of the slots. Instead of a motor and pulley system, disc 43 may carry a flywheel. Starting from rest, as shaft 27 is driven clockwise (Fig. 8) the pins will move to the opposite ends of the slot to those indicated. On changing the speed from 18 to 5 frames per second, the flywheel inertia will bring the system to the condition shown. The speed of the main asynchronous driving motor may be changed by shorting out part of a winding in parallel with the main winding.

Abstract: 566,510. Concrete beams ; floors &c. SHARP, A. April 17, 1943, Nos. 6196 and 8250. [Class 20 (iv)] A reinforced-concrete beam for use in the construction of fireproof floors, roofs, walls and the like, is of channel section and has the face of its web 10 shouldered longitudinally to form longitudinal recesses at the corners of the web, with which recesses the edges of the flanges of an adjacent beam may engage. In the construction shown in Fig. 1, the flanges of the beam are braced at intervals by reinforced webs 13, the reinforcements of which are connected to longitudinal reinforcing rods 12. When used for constructing walls, each beam is laid horizontally with the outer faces 131 of webs 13 'resting on the outer face of the web 10 of an adjacent beam. A continuous cavity throughout the wall is obtained by making spaced apertures in the webs, and adjacent beams may be bound together by cement mortar disposed between V-grooves 132 in the webs 13 and the webs 10. In a modification, Fig. 3 (not shown), the upper flange of a floor beam is shorter than the lower flange and the cavities thus formed between adjacent beams are filled with concrete. In Fig. 5, the two channel - section beams have interengaging flanges, those of one beam having rounded beads 112 and those of the other corresponding recesses 111. The webs 10 of the end beam are engaged by the flanges of a beam 22 and the floor is continued by further beams having recessed flanges. The beams may be shaped to provide apertures 24 through which concrete or cement may be housed to fill the cavities 25. The first Provisional Specification also describes a floor construction in which recesses are made in the longitudinal edges into which grouting material is poured, and also a construction in which the upper faces of the beams are recessed so that a pair of spaced parallel beams may accommodate a bridging slab laid in the opposed recesses. A modified beam construction comprises an upper flange extending in one direction from a web and a lower flange extending in the opposite direction, the top of the web being recessed to receive the bead or rib on the edge of the adjacent beam.
