In a cueing system for television there are added to the television waveform during at least one line of the frame suppression period, plural different cue signals occurring one after another throughout the line period. Each signal consists of a burst of a sine wave of a predetermined frequency, a different frequency being employed for each different cue signal. The arrangement at the transmitting terminal is shown in Fig. 2, where a generator 10 controlled by vertical and horizontal synchronizing pulses produces first and second half-line duration pulses coinciding with the respective halves of a predetermined line of the frame suppression interval, the pulses being applied each through a selected one of a group of switches 13 to key a burst generator 11. In this way a time division conbination of two signals, each having a different frequency, is generated and added to the transmitted video signal in a mixer 14. At the receiving terminal, Fig. 1, a gate 2 controlled appropriately by vertical and horizontal synchronizing pulses derived by a separater stage 1 separates out the line during the frame suppression interval which contains the cueing signal and applies the signal through a switch operating a halfline interval to two groups of tuned circuits 4, each arranged to trigger an associated relay or other control device 5. In accordance with the pattern of operated devices 5, a desired control operation is performed. The invention is stated to be of use for automatic switching in line and V.H.F. networks, and the control of domestic apparatus, e.g. in connection with prepayment television.

Patent GB-771082-A (GB)
Title: Quaternary ammonium compounds
Inventor: VASSEL BRUNO
Filed: 1955-01-08
Abstract: A process for the synthesis of a betaine hydrate comprises reacting an aqueous solution containing at least two mols. of a water-soluble trialkylamine having a boiling point below 100 DEG  C. per mol. of halo-acetic acid with haloacetic acid, subjecting the solution to treatment with a strong anion-exchange resin, distilling the trialkylamine from the effluent from the anion exchange material and crystallizing the betaine hydrate from the resulting aqueous residue. Suitably 2 to 3 mols. especially 2.2 mols. of trialkylamine per mol. of haloacetic acid, are employed. Excess trialkylamine may be distilled from the reaction mixture before the treatment with the anion-exchange resin and from the effluent from the anion-exchange treatment.  The combined distillates may then be recycled as a 20 per cent solution for reaction with further haloacetic acid or admixed with sodium hydroxide solution, followed by distillation, the distillate of trialkylamine being recycled and the sodium hydroxide residue being used to regenerate the anion-exchange resin.  Resins referred to are reaction products of aromatic amines and formaldehyde or a polyamine, a phenol and formaldehyde, or polystyrene divinyl-benzene resins containing quaternary amines. In examples: (1) chloracetic acid (1 mol.) and aqueous trimethylamine (2.2 mols.) are reacted together, free trimethylamine is distilled off and the mixture after dilution is passed over an "Amberlite" IRA 410 (Registered Trade Mark) anion exchange resin.  Trimethylamine is distilled from the effluent, which is further concentrated and betaine hydrate then crystallizes out.  The trimethylamine distillates are heated with sodium hydroxide, trimethylamine is distilled off the mixture into water, giving a 20 per cent solution suitable for reaction in a subsequent batch, and the sodium hydroxide solution remaining is used, after dilution, for regeneration of the anion-exchange material; (2) a similar reaction is effected using triethylamine and omitting the separation of excess triethyl amine before the anion-exchange resin treatment.

Abstract: 678,527. Testing hardness of materials. G.K.N. GROUP SERVICES, Ltd., and TOWNEND, G. H. Jan. 15, 1951 [Jan. 14, 1950], No. 979/50. Class 106 (ii). An apparatus for testing the hardness of a specimen by forcing an indenter into its surface under a known load comprises a bench-type microscope 14, Fig. 1, having a rotatable carrier 10 for its objectives 12, Fig. 2, and for pivotally supporting a balance beam 17 carrying an indenter 18, the beam being such that, when balanced, its pivotal axis 21 is in the same horizontal plane as the point ot the indenter 18. The vertical axis through the point of the indenter 18 and the centres of the objectives 12 all have the same path of rotation such that the indenter point 18 or any of the objectives 12 may be aligned with the optical axis of the microscope. The beam 17 is pivotally supported by two flat torsion springs 20, Fig. 2, the outer ends of the springs 20 being connected to screws 21 threaded in clamping means 19. By turning the screws 21 the beam 17 may be roughly balanced, a final balance being made by means of a weight 24 threaded on an extension 23 of the beam 17. In carrying out a test, a specimen (not shown), is mounted on a stage 31 slidable in its own plane in two. directions at right angles to each other against the action of springs by means of two micrometers 45 so that a chosen point on the specimen may be brought into coincidence with the focal axis of the microscope 14. The carrier 10 is now turned to bring the indenter 18, on the accurately balanced beam 17, over the said point, and a weight is applied to the end 32 of the beam 17. The indenter point 18 is now.brought into engagement with the specimen by the usual focusing mechanism of the microscope and an indication of when the load has been taken up by the specimen is given electrically when a contact 29 on the beam 17 is moved away from a stop 26 against which it normally rests which the beam 17 is loaded at 32. After a suitable period, the indenter is withdrawn by operating the focusing mechanism in the reverse direction, and the impression made is then examined microscopically and measured to deduce hardness. The rotatable carrier 10 may be held in its desired positions by any suitable means such as for example, spring.-loaded balls engaging in notches in a plate 11. The objectives 12 are adjustable in the plane of the rotatable carrier 10 by screws 16, Fig. 2.

Title: Pulse width transmission system
Inventor: KATSUMATA KENICHIROU
IPC: H03M5/08
Filed: 1981-01-06
Abstract: PURPOSE:To reject the distortion of pulse by a transmission line, by transmitting data pulse added with a specified pulse and subtracting the added pulse at reception. CONSTITUTION:At a transmission end 1, an offset pulse with a width corresponding to an offset current 5 is outputted after being coupled with the front end of the pulse with a width corresponding to a data current 6 at each channel. In this case, the offset pulse with a width corresponding to the offset current 5 is also outputted. At a reception end 2, a pulse and an offset pulse at each channel are received and the front end of the pulse is cut at an AND gate 8. A subtraction circuit 12 outputs a pulse width subtracting the offset pulse cut at the front end from the pulse of each channel cut at the front end as a data pulse. As a result, the adverse effect due to the distortion of pulse front end generated on the transmission line is eliminated.
