Title: Improvements relating to optical apparatus for indicating the location of a body relative to a straight line
Inventor: DYSON JAMES
IPC: G02B27/64
Filed: 1958-09-15
Abstract: 877,922. Optical aligning apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 7, 1959 [Sept. 15, 1958], No. 29493/58. Class 97(1) The optical apparatus for indicating the distance of a body from a straight line comprises a circular diffraction grating on which a beam of light is projected from a light source, an optical system located on a side of the diffraction grating remote from the light source and arranged so that the image of the light source includes a line extending from the grating centre towards the light source and optical viewing means attached to the body and associated with a reference mark whereby the distance of the body from the reference line may be used for aligning three or more bodies B1, B2, B3 and comprises a circular diffraction grating G on which light from a source S is projected. Behind the grating is a lens L 1  having its principal focus at the apex of a concave mirror M, the system L 1  and M serving to form an image of the grating G on the grating itself. Hence an image of the light source S is formed which includes a line extending from the grating centre towards the light source S and in this line image is disposed a prism P carried by a box D provided with lenses L 2 , L 3 , adjustable cross-hairs W and a pointer C for contacting a bearing surface. The box D is placed in turn in the bearing housing B 1 , B 3  with the pointer C in contact and so that the reference line coincides with the cross-wire in each position. The pointer C is then placed in contact with the bearing housing B 2  so that non- alignment will be inducted by the reference line not coinciding with the cross-wires. A measure of the non-alignment is obtained by moving the cross-wires by a micrometer. Specification 862,290 is referred to.

Title: Improvements relating to coin-freed apparatus
IPC: G07F11/18
Filed: 1939-11-07
Abstract: 534,298. Coin-freed apparatus. PARNALL & SONS, Ltd. (Wistoft, S.). Nov. 7, 1939, No. 29532. [Class 27] In coin-freed apparatus for the delivery of articles of different prices the delivery elements (such as drawers 1 ... 4) are individually corrected by transmission members 5 ... 8 to corresponding coin-freed devices (not shown). at least one of the drawers being capable of being connected by an official to more than one of the coin-freed devices so that this drawer can be set for the sale of articles of a value equal to that of two coins. In the construction shown in Fig. 2 each of four bars 5 ... 8 has a bracket 15 ... 18 carrying a pin 12, some of the brackets being offset so that all the pins are in line. Each drawer 1 ... 4 acts on a corresponding cam lever 14 so that when drawer 1, for instance, is drawn out its lever 14 acts on the pin 12 of bar 5 and moves this bar to the right, this movement 'however being prevented unless an appropriate coin, say 1 mark, has been inserted. Similarly, if a 50 pfennig piece is inserted in the appropriate coin slot bar 6 is released, and the drawer 2 can be drawn out thereby moving bar 6 to the right. In the same manner drawer 4, acting on bar 8, can be drawn out when a 10 pfennig piece is inserted. Drawer 3 acts on bar 7, which abuts bar 8 and carries a bracket 19 adapted to engage a pin 20 on bar 6, so that this drawer can only be drawn out if both bars 6 and 8 are released by the insertion of 60 pfennigs. Any drawer can be similarly connected to any desired bar and coin-freed device. In a modification each cam lever 14 acts on a lever carrying a detachable member adapted to engage and operate one or more of the bars 5 ... 8. In the construction shown in Fig. 5, each drawer 1 rocks a lever 41 which can be connected by links 37, 38 or 39 to any or all of shafts 31, 32, 33 connected to the coin-freed devices, so that any desired combination of prices can be arranged for.

Filed: 1938-10-13
Abstract: 504,258. Current and voltage measarements ; wireless systems. LORENZ AKT.-GES., C. Oct. 13, 1938, No. 29689. Convention date, Oct. 13, 1937. [Class 37] [Also in Group XL] In apparatus for comparing electric quantities, rectifiers or resistances are interchanged with one another in rapid succession in order to eliminate errors due to differencies in their characteristics. A circuit arrangement is shown for comparing alternating currents of two different frequencies as applied, for example, in the wireless direction of vehicles by comparing the field, strength of two differently modulated antenna fields. The received signals are rectified in a receiver E and amplified, and conveyed through a transformer T to resonance circuits S1, S2 tuned to the two frequencies. The voltages arising at the oscillator circuits and the currents produced thereby are rectified by rectifiers G1, G2 and compared by a D.C. indicator I, equality being shown by zero deflection. In order to compensate for differences in the characteristics of the rectifiers G1, G2, these are interchanged in rapid succession by means of a rotating roller or other mechanical switch or by means of electric discharge tubes. The invention is applicable also in circuits in which resistances having differing characteristics are employed.

Title: Television waveform generator
IPC: H04N5/067
Filed: 1973-06-22
Abstract: 1427956 Television BRITISH BROADCASTING CORP 21 June 1974 [22 June 1973] 29812/73 Heading H4F  Television waveform generator 14 providing a local television waveform in response to a local clock 10 is synchronized to a reference television waveform applied to an input 20 by detecting 31 field synchronizing signals of the reference waveform and by means of a gate 33 determining if such a detected field sync signal is less than N lines early with respect to the local field sync. signal, and by means of a gate 32 determining if it is more than N lines early i.e. late, with respect to the local field sync. signal. If an output is passed by gate 32 the local field period is lengthened by N (e.g. 2 or 4) lines due to counter 34 inhibiting gate 12 from passing clock pulses at twice line frequency to a counter 11 which provides pulses at twice frame i.e. field, rate to generator 14. The local field period is thus successively at field rate lengthened (vide 52 and 53, Fig. 2) by N lines until the external field sync. is early with respect to the local field sync., in which case an output is provided by gate 33 to reset counter 11 thereby causing the local field sync. to jump (e.g. 54, Fig. 2) into synchronism with the external field sync. Local line sync. is synchronized with the reference line sync. by controlling clock 10 in response to the mark-space ratio of the filtered 24 output of a bi-stable 23 triggered by line sync. pulses from generator 14 and cleared by detected 21 external line sync. pulses. When in synchronism the mark-space ratio is arranged to be 1:1. An additional circuit 35 is provided to ensure that the extra N lines due to the lengthening of the locally generated waveform occur during the picture rather than during the production of sync. signals between fields. Both gates 32 and 33 are closed during the first “ line of the locally generated field sync. pulses so that when synchronism is achieved it is not disturbed. In addition to the synchronization operation 52, 53, 54 referred to above, Fig. 2 also shows (a) a direct jump into synchronism at 55 when the external field is an even number of lines late, (b) lines added at 56 and 57 when 2¢ and 1¢ lines late until the external field sync. are less than 2 lines early and then counter 11 reset, in which case two consecutive fields of the same parity are produced as a result of a jump of an odd number of half lines. For a PAL colour television signal, generator 14 is arranged to include a burst controlled oscillator responsive to colour subcarrier signal bursts in the reference waveform to produce a local colour subcarrier signal.

Title: Improvements in and relating to the heat treatment of metals
IPC: C21D1/76
Filed: 1936-11-03
Abstract: 484,569. Furnace atmospheres. PEARSON. J. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 3, 1936, No. 29942. [Class 51 (ii)] In the heat treatment of metals in a protective atmosphere in batch-type furnaces, e.g. furnaces of the bell type, the purging gas, which is supplied after charging and before discharging for clearing the furnace chamber of air and protective gas respectively, is collected and recirculated for use after regeneration. In the apparatus shown diagrammatically in the Figure, three furnaces 12, 13, 14 are in communication through valve-controlled pipes 10, 11 with supply and exhaust mains 17, 18 for protective gas, and can also be connected to atmosphere through the valves 16a, 16b, 16c and the conduits 25a, 25b, 25c. The exhaust main 18 leads to a large capacity flow-equalizing vessel 26, which in turn is connected to the supply main through a fan 19 and regenerating chamber 20. Flow of gas through the regenerating chamber is maintained, irrespective of fluctuations in gas flow from the furnaces, by an automatic valve 21 in a cross connection between two flow-equalizing vessels 22, 23. During purging after charging the protective gas is first allowed to escape to atmosphere for a short time, and is subsequently collected in the vessel 26 for re-use after regeneration. At the end of the heating operation gas may be driven from the furnace by air supplied through an inlet connection, and in this case only the gas from the early stages of the purging operation would be collected. Gas supplied to the furnace during the heating operation is also recirculated for re-use. Regeneration of the gas is effected by burning the oxygen content with a reducing constituent of the protective gas, or with ammonia or other fuel gas from which the protective gas is produced. In a modification. Fig. 2 (not shown), the vessel 26 is arranged on the furnace side of the regenerating chamber 20, and is in valved commumcation with each of the furnaces. In other forms, Figs. 4 and 5 (not shown), two vessels 26 are connected in parallel in the circuit, and one of them is used for collecting gas with a high oxygen concentration. Three collecting-vessels may be used, one for the gas from the early stages of purging after charging, another for gas from the later stages, and gas used during the heating-operation, and the third for gas from the purging before discharging. Specification 429,940 is referred to.
