Patent GB-1604562-A (GB)
Title: Process for keeping clean internal and external surfaces in danger of contamination
IPC: C11D3/37
Filed: 1978-05-25
Abstract: To keep clean internal or external surfaces at risk of fouling, a protective layer is applied to the surfaces to be treated and after fouling has taken place, the dirt is removed. For this purpose, a film former composition is used in the form of a solution or dispersion which contains a film former which, after drying, forms a protective layer which is soluble in water, sparingly soluble in water, sparingly soluble in water but swellable, insoluble in water or insoluble in water but swellable. This film former composition is applied to the surface to be treated and allowed to dry. The surface obtained in this manner, furnished with a protective coating, after fouling has occurred, is treated with a film former composition or with water or an aqueous medium for cleaning, at least part of the protective coating being left. Virtually all types of surfaces can be treated in this manner, in particular glass, ceramics, metal, plastics, wood, carpets and fabrics, and it is irrelevant whether these are internal or external surfaces.

Title: Subscription television system
IPC: H04N7/16
Filed: 1962-06-13
Abstract: 1,003,528. Radio signalling. BRITISH TELEMETER HOME VIEWING Ltd. June 13, 1962 [June 13, 1961], No. 22773/62. Heading H4L. Relates to a subscription television system of the type disclosed in Specification 985,603, in which the transmitter sends by line video programme signals, control signals including pricing information, recording information for identifying the programme, " barker " frequencymodulated audio signals giving preliminary information concerning the programme, and an unmodulated pilot carrier signal. Each subscriber is provided with a receiver attachment including a local osillator for converting the received signals to the correct frequencies for application to a conventional television receiver. Only when payment has been met can the output of the local oscillator be coupled to the video and audio programme signals so that they can be applied to the normal aerial input of the receiver. In the prior arrangement the " barker " signal and pilot carrier after frequency-changing in the receiver attachment are applied to the receiver aerial circuit at the correct frequencies to provide intercarrier sound reception, but the present invention permits the reception of the " barker " signals by the intercarrier sound system without the necessity of transmitting the two carriers. This part of the system shown in Fig. 2, the " barker " signal 32 at the transmitter frequency-modulating a 4À5 Mc/s. carrier and being supplied over a line 38 to the attachments at the subscribers' receivers. When information regarding a programme is desired the switch 41A, 41B, 41C is moved to the position shown and the " barker " signal is selected by a filter 42 and fed to a frequency converter 44. In this position a local oscillator coupled to the frequency changer provides a frequency of, say, 87.75 Mc/s. whereby the frequency changer produces an output signal of 83À25 Mc/s. The unmodulated carrier of 87À75 Mc/s. also appears in the output of the frequency-changer and these two signals are supplied to the input circuit of the television receiver to provide intercarrier sound working and thus produce a 4À5 Mc/s. frequency-modulated carrier for the " barker " signal. The " barker " signals also may be received on a receiver not of the intercarrier type.
