Title: Hard, refractory crystalline materials
IPC: C04B14/32
Filed: 1959-11-25
Abstract: A composition of matter containing at least substantially 80, usually 79.6-86.5%, combined boron and at least 6, usually 6-20%, combined silicon, with, or without, up to 8, usually 1-3%, carbon, is prepared either by melting silicon hexaboride SiB6, or by fusion of the elements.  The amount of carbon depends upon that derived from the surroundings, or that added to the raw batch.  SiB6 is melted in a boron nitride crucible having a boron nitride lid packed in boron nitride powder in a graphite crucible by heating in an induction furnace to 2250 DEG  C. for 30 mins.-1 hr. in an argon atmosphere. After cooling in argon, free silicon is removed by treatment with an HF-HNO3 mixture, the residue is dried and fused with KOH to remove nitride, to give a compound having an approximately empirical formula SiB12 in rhombic crystals.  Si and B may be fused together by the same sequence of operations. The carbon-free product has an average hardness 2624 and the carbon-containing product 2868 and both scratch Si and B carbides.

Title: Improvements in or relating to pickup-depositing mechanism in gramophone record players
Inventor: HUMBY EDWARD THOMAS
Filed: 1967-09-01
Abstract: 1,239,905. Record player. GARRARD ENG. Ltd. 22 Aug., 1968 [1 Sept., 1967], No. 40056/67. Heading G5R. In a record player with an automatic change mechanism, skating immediately the pick-up is deposited on a record is reduced by a stabilizing lever 25 which is coupled to pick-up plate 9 via a friction arm 20 and frees the pick-up arm 8 from restraint to play the record after the arm has been moved outwardly by a standard lead-in groove pitch-to ensure that stylus is engaged in a groove and then restrained during half a record revolution to a controlled rate of movement towards the turn-table axis to release any accumulated resilient-energy in the arm and pick-up. Cycling cam 3 of the auto-change mechanism initially drives plate 5 anti-clockwise about pivot 6 during which pin 13 on pick-up plate 9 engages in the narrow end of slot 15 on arm 11 and the pick-up arm 8 is pivoted 10 with the plate 9 to its outermost position. Additionally, tab 23 at the end of friction arm 20 engages the bottom portion of a slot 24 in stabilizing lever 25 and is locked against further movement about its pivot 10. Cycling cam 3 then drives plate 5 clockwise, whereby the wedging action of pin 13 in the narrow end of slot 15 on arm 11 ensures movement of the pick-up plate and arm towards a position over a newly deposited record defined in dependences on record size by the position of stop 16 with respect to steps 17 on plate 9. The pick-up arm is lowered via pin 19 and since pin 13 is now free in the slot 15 the pick-up arm is only restrained by the frictional coupling between the pick-up plate and the arm 20. As the pick-up engages the record, pin 26 on the stabilizing lever is engaged by the end 29 of slot 28 in plate 5 to move the slot 24 out of arrangement with tab 23 in the friction arm 20. The first part of this movement allows a slight amount of play to the pick-up arm then the tab 23 engages a cam 33 on the side of the slot which moves the pick-up outwardly by half the pitch of a standard lead-in groove during the period of one half revolution of the turntable. This ensures that the pick-up has engaged a lead-in groove in the record. Thereafter the cam edge 33 recedes permitting controlled release of any resilient energy in the pick-up and arm due to feed of the pick-up along the lead-in groove. This release period extends during a further half revolution of the turntable after which the tab 23 leaves the slot and the pick-up arm is freed to play the record.

Abstract: 1287434 Image transmission system PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 Aug 1969 [14 Aug 1968] 40103/69 Heading G2J [Also in Divisions H4 H1] An image transmission system comprises a luminescent screen 31, Fig.3, for collecting radiation 29 and which is optically coupled with a photo-conductive layer 44, consisting mainly of lead monoxide, of a vidicon type camera tube 35, by a fibre optic stack 34, and wherein an image transmission path is provided for transmitting from the screen to said layer substantially only that emission of wavelength less than 4000Š. The penetration of long wavelength radiation from the screen in the tetragonal lead monoxide layer of the target plate (13) Fig.2 (not shown) is greater than that of shorter wavelength radiation so that an overlap of the beams from adjacent fibres (14) is produced giving a loss of definition on the television screen of a monitor fed from the camera. Accordingly a filtering means for radiation e.g. from the electron-optical device illustrated is provided to cut out radiation greater than 4000Š. This may be provided either by a vapour deposited silver filter 48 placed intermediate two parts 34, 33, of the fibre optic stack or by making the cores of the fibres of the stack transparent only to radiation of wavelength less than 4000Š or a combination of both. Also as shown radiation beam 29 may either be transmitted to the camera 35 through screen 31 provided with a filtering means of cerium activated calcium magnesium silicate or silver activated zinc cadmium sulphate to filter out radiation substantially above 4000Š or to a screen 30 e. g. of silver activated zinc sulphide for visual observation. If only a single screen is provided then screen 31 is provided with a phosphor having two luminescence peaks, one in the green spectral region for visual observation through a window 47 and the other at a wavelength less than 4000Š for transmission to the photo-conductive layer of the camera tube. The cores of the fibres in the stack may be provided with a black cladding. Reference has been directed by the Comptroller to Specification 1135153.

Title: Apparatus for Compensating Timing Errors in a Television Signal
IPC: H04N5/95
Filed: 1966-09-16
Abstract: 1,150,482. Automatic phase lock. FERNSEH G.m.b.H. 16 Sept., 1966 [16 Sept., 1965], No. 41483/66. Heading H3A. In an apparatus for correcting errors in timing of a television signal, e.g. from a magnetic recorder, in which the signal is passed through a tapped delay line and is taken out from that tapping at which oscillatory time markers contained in the television waveform deviate least in timing from reference oscillatory time marker signals, each tap has associated with it apparatus which combines the reference time marker in antiphase with the time marker from the television signal, the resulting signal is rectified and the stage is determined at which that voltage is a minimum and the television signal is extracted from that stage. In Fig. 1 a line 1 has tappings 11 to 23 each having a switching and comparison stage such as 50 or 60 connected thereto in which reference oscillations applied at b are added, in antiphase, to the oscillatory time marker signals in the signal from the respective tap in the adder 51. The resulting signal is rectified in 52 and the mean value obtained in 53 from which is subtracted, in 59, the mean value determined for the previous tap, and is passed on only if the difference is positive. In 54 only signals below a predetermined value are passed to be sampled at the end of each comparison period by a gating pulse A applied to switch 55, and the appropriate value is stored in store 56, which is reset by a pulse L immediately before the gating pulse A, and operates switch 57 to connect the output from the respective tap to the output mixer 4. An additional switch 58 is provided in the signal connection which is opened if the adjacent device responds and so prevents two adjacent switches being operated when the delay required is that intermediate two taps. In an alternative embodiment, Fig. 3 (not shown), each stage has a logic circuit which compares the mean value derived in respect of the tap to which the stage is connected with the mean value derived in respect of the preceding and succeeding stages so that an output is provided only for the stage having the minimum mean value. Another alternative arrangement, Fig. 4 (not shown), includes a diode network connected to the mean value output of all the stages, to derive a voltage corresponding to the minimum mean value. The minimum mean value is then used as a reference potential in a limiter circuit so that only the minimum mean value is passed into the respective store (56) to operate the respective output switch (57).
