Title: Improvements in thermionic valves
IPC: H01J19/78
Filed: 1925-10-14
Abstract: 264,234. Marconi, G., and Franklin, C. S. Oct. 14, 1925. Vacuum tubes.- A valve for generating very short waves has the oscillatory circuit entirely within the valve and the seals for making connection to the anode and grid carry only the anode feed and grid currents respectively. As shown in Fig. 1 the grid G is supported by a metal cone, or strips X lying along the surface of a cone, on a ring O encircling the glass foot W, and the anode A is supported by a metal cylinder, or strips Y lying along a cylindrical surface, on a ring P separated from the ring O by insulation M. The capacity between the rings should be large compared with the capacity between the grid and anode. The oscillatory circuit consists of the capacity between the rings, and between the grid and anode, in series with the inductance of the strips. The rings O, P are connected with seals G S, A S respectively. The valve shown in Fig. 2 has two sets of electrodes, the grids G<1>, G<2> and anodes A<1>, A<2> being connected by metal strips X, Y respectively, connection to the seals being made from the centre points of the strips. The grids and anodes may be supported from the ends of the envelope. Energy is transferred to an external circuit such as a tuned aerial by means of a small condenser in the filament leads on the valve side of chokes, or by electrostatic induction through the envelope; or the aerial may be mounted within the envelope.

Title: Type-Composing Apparatus
IPC: B41B27/00
Filed: 1966-06-10
Abstract: 1,159,191. Type composing machines. HARRIS-INTERTYPE CORP. 10 June, 1966 [11 June, 1965], No. 26067/66. Heading B6W. Escapement control mechanism.-Type-composing equipment comprises the combination of a keyboard for selection of a sequence of characters and spaces to make up lines of composition, an encoding device comprising switches operated by the keyboard to produce a distinctive code for each operation of the keyboard identifying the character or function selected, an electronic shift register connected to receive the output of the encoding device and operating to retain each code therein, a type-composing machine operative to produce justified lines of type by assembling the individually selected characters and spaces in the order determined by operation of the keyboard, a decoding device controlling the type-composing machine and connected to operate from the shift register for decoding the codes stored therein into control signals for the type-composing machine, and reading means operative on the decoding device and the shift register to enable codes to be passed on from the register on demand from the decoder according to the rate at which the type-composing machine can perform the operations directed by the decoding device. In a preferred embodiment the keyboard includes output switches which are closed according to the code of the key depressed and a " last-closing " switch which closes when any key is depressed but after the code switches. When this last switch closes, an output code is set up in the first stage of the shift register " B register." Outputs from this register extend to a record stage " A register ". The speed at which codes pass from the A register to the decoder and from the B to the A register is controlled by clock pulses fed to the A and B registers, such pulses being timed to the operating cycle of the type-composing machine, e.g. the matrix escapement mechanism cycle. A zero detector circuit is connected to sample the B register and inhibit the passage of the next code from the encoding switches to the B register until the register is clear. A circuit capable of detecting wherever the same code word is encoded twice in succession, e.g. by comparing the code already in the B register and the next code set up in the encoding switches, may be provided, which circuit operates to delay the transfer of such a successive code word to the decoding device, e.g. by preventing one clock pulse from reaching the B register. The type-composing machine may be one of the recirculating matrix type in either the line-casting or photo-composing form.

Title: Improvements in or relating to radio direction finding
Inventor: ELLIS ALFRED BRIAN EDWIN
IPC: G01S3/14
Filed: 1966-06-11
Abstract: 1,107,965. Radio direction-finding. MARCONI CO. Ltd. 14 Feb., 1967 [11 June. 1966], No. 26105/66. Heading H4D. In a known radio direction-finder a switchable directional aerial system is arranged in any condition of switching to exhibit simultaneously two component radiation patterns, each including two angularly spaced main lobes-e.g. 1L, 2L and L1, L2, Fig. 2-with a common null separation direction N. If the elevation of an incoming signal is to be found the main lobes are arranged to lie in a vertical plane. The two lobes on the same side of direction N are either in-phase or in phase opposition, switching means being provided to control phasing and connections of the parts of the aerial system so that, in each position of switching, there are two different radiation patterns with a common direction N, but when switching is changed, that direction is shifted. One aerial system comprises a stacked array 1, Fig. 1, of horizontal loops connected by individual feeders to a phasing and switch control unit 2 energized from a remote controller 3 incorporating a scale showing the elevation of direction N. The outputs are corresponding to the two component diagrams of Fig. 2 are fed to receivers 4, 5 having a common local oscillator 6 and the receiver outputs are fed to a phase comparator 7 adapted to afford zero output when the two inputs are in-phase or in phase opposition. Thus, when controller 3 is set such that there is zero output from comparator 7, the incoming signal direction can be read. However, since the incoming signal will generally be an ionospheric reflexion, and may also be noisy, a clearly perceptible zero output from the comparator will not occur and according to the present invention the output of comparator 7 is fed to a device 8 which provides an output only when its input exceeds a predetermined and low threshold value, and this output opens a normally-closed gate 9 to permit pulses at a predetermined repetition rate from a source 10 to pass to a counter 11 operating for a fixed time interval. The count is made in each position of variation of direction N. Figure 3 exemplifies a histogram of the counts, D1 and D2 representing incoming signal directions. The successive counts may be displayed on a cathode-ray tube.

Title: Improvements in or relating to adjustable-clearance antifriction bearings
IPC: F16C19/28
Filed: 1958-08-15
Abstract: 864,465. Bearings. SCHAEFFLER, W., and SCHAEFFLER, G., [trading as INDUSTRIEWERK SCHAEFFLER OHG]. Aug. 15, 1958 [Aug. 16, 1957], No. 26311/58. Class 12 (1). In a bearing comprising an outer race 2 and rollers 7 bearing directly on a shaft 8, the clearance is adjustable by means of a ring 3 of deformable material located between the outer race 2 and housing 4 and compressed axially by rings 5, the compression causing reduction of the race diameter. In a modification, a ring 27 of deformable material is located between split lateral rims 31, 32 of a race 22, Fig. 4. Axial pressure applied by a flange 32 causes bending of the race 22 in addition to deformation produced by compression of the ring 27. In another modification, shown in Fig. 5, deformable rings 34 are located in circumferential grooves in the outer surface of a race 33. In a further modification, a race 39, Fig. 6, provided with a recess 40 which accommodates an elasticallydeformable ring 41, is introduced under pressure into a housing 43 so that a cambered raceway is formed. By tightening a nut 46, the camber is reduced and hence the clearance increased. Fig. 7 shows an arrangement in which a race 47 is constructed as an elastic element which may be deformed by axial adjustment of a threaded nut 53, elastically deformable rings being inserted in outer recesses 48 of the race 47. In another modification, shown in Fig. 3, a plastic ring 15, located in a groove in a race 14, is compressed by a threaded ring 18 acting on a ring 17 carrying pins 16<SP>1</SP> which pass through apertures in the end wall of the race 14. The invention may be applied to an inner race.

Title: Continuously variable speed gear
IPC: F16H37/08
Filed: 1933-09-25
Abstract: 424,018. Variable speed gearing. PLATZER, J., 8, Burschlweg, Landeck, Tyrol, Austria. Sept. 25, 1933, No. 26399. Convention date, Feb. 23. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 29, 1934.] [Class 80 (ii)] Continuously variable - speed ratchet gearing, for controlling a sun-wheel 7 in a three-element epicyclic train 14, utilises the cyclic speed variations of a universal joint 2, all the axes of the ratchet gear remaining stationary so long as the ratio is unchanged. The final drivenshaft 9 carries a sun-wheel 8, whilst the driving-shaft 1 is secured to the planet-carrier 14 and also drives the control sun-wheel 7, through spur-gearing 12, 13, universal joint 2, bevel-gearing 3, 4, ratchet 5, and bevel gearing 10, 11. For obtaining a reversible and bi-directional drive, the bevel wheel 7 is also driven through a similar gearing, shown with indexed referencenumerals and having a difference referred to below. The bevel-wheel 3 is adjusted about the axis of the joint 2 for producing the cyclic variation in speed of the driving member of the ratchet 5. The ratio of the toothed gearing is so chosen that, near the coaxial position of the bevel 3, the sun-wheel 7 rotates at twice the speed of the driving-planet-carrier 14, causing standstill of the driven sun 8. The speed of the control sun 7 is then progressively reduced to cause rotation of the driven sun 8 at increasing speeds. For this purpose the minimum fluctuating speeds of the joint 2 are utilized, the ratchet 5 being arranged to act as a detent in such a way that its driving- member can overrun its driven-member in the forward, but not in the reverse direction of drive, whereby the maximum impulses of the joint cause idle overrun in the ratchet 5. For reversing the direction of rotation of the driven sun 8, the lower ratchet gear is used. The driven-member of the ratchet 5<1> of this gear can overrun only in the forward direction in the usual manner, so that the maximum fluctuating speeds of the joint 2<1> are used to increase the speed of the sun-wheel 7 beyond twice that of the planet-carrier 14 and so reverse the drivenshaft 9. Whilst either one gear is operating with its bevel 3 or 3<1> out of the coaxial position, the other is maintained in the coaxial position and its ratchet overruns idly. In Fig. 1, not shown, only the upper ratchet gear is used, and the drive may be rendered bi-directional by an irreversible worm gear between the ratchet 5 and the bevel 10. The ratchet 5 may be arranged between the joint 2 and the bevel 3, and flexible shafting may replace the bevelgearing 3, 4. To obtain greater uniformity of drive, inertia-masses may be placed on the driven shaft of the ratchet gear or on the final driven shaft, or two or more universal joints may be arranged to deliver impulses in succession. Specification 415,896 is referred to.
