Title: Compensating for temperature change of quartz oscillator frequency
IPC: H03K23/00
Filed: 1978-09-07
Abstract: The time standard of a quartz electronic timepiece has two quartz oscillators of different predetermined temperature/frequency characteristics but the same frequency at a given temperature in the working temperature range. The oscillations used to control the time display are made substantially independent of temperature variation over the range by producing a beat frequency between the outputs of the oscillators (or frequency divided oscillations derived therefrom) and effectively adding the resultant to the output of one oscillator (or to frequency divided oscillations derived therefrom). In an embodiment, one oscillator (f1) has half the temperature coefficient of the other (f2), and adding the beat frequency (f1- f2) to the frequency of the former (f1) produces a frequency (2f1-f2) substantially compensated for temperature change. <IMAGE>

Filed: 1979-02-13
Abstract: In some telephone systems unsuccessful (no answer or line engaged) calling subscriber numbers can be stored in the called subscriber station and automatically retrieved for connection establishment when the called subscriber instigates the retrieval. However, the retrieval and connection establishment is automatic, in accordance with presetting of the apparatus in the called station. Apparatus is now provided to display (AZ) the total number of stored numbers and to display visually the numbers themselves, switches (WT) enabling stored number erasure and/or connection establishment selectively on the basis of the number displayed and the decision of the subscriber viewing the display. Facilities (T1 to Tx, Tu) are provided for forwarding selected or all displayed numbers to a substitute station. Call-up means (ABS) enables repetitive display of the sequence of stored numbers so that a selected number can be used for connection establishment during a respective call-up cycle.

Patent GB-2015430-A (GB)
Title: Taking Fingerprints
IPC: A61B5/117
Filed: 1979-02-26
Abstract: A first method of revealing a fingerprint involves the charging of the surface bearing the fingerprint to a high electric potential and applying finely divided carbon to the charged surface to form a pattern thereon corresponding to the fingerprint. The finely divided carbon may be dusted or sprayed on or may be in suspension in a dielectric liquid into which the charged surface is introduced. In another method the surface is charged whilst submerged in the dielectric liquid, under the action of an electric field in the dielectric. In another method an electrically charged sheet is brought into contact with a surface bearing a fingerprint and after being removed, the charged sheet has applied to its surface finely divided carbon which adheres thereto depending on the charge pattern remaining thereon after contact with the fingerprint. The pattern of finely divided carbon can be fixed in position by applying thereover a transparent protective layer.

Title: Deriving a PAL colour television signal corresponding to any desired field in an 8-field PAL sequence from one stored field or picture of a PAL signal
IPC: H04N9/877
Filed: 1979-05-22
Abstract: A single field or picture of a PAL colour television signal is stored in a store and provides a signal at an input (52). The stored signal consists of 2fsc samples taken at 45 DEG  to the U-axis.The signal is separated by a filter (56) and subtractor (58) into a high frequency or chrominance signal and a low frequency or luminance signal. The chrominance signal is delayed by delay means (62) such that the chrominance components of two lines which are an odd number of lines apart are made available simultaneously. These signals are combined by switches (S1, S2) and/or combining circuits (68) to provide a signal at 4fsc which is combined with the luminance signal in a combining circuit (70) to provide a 4fsc PAL output (72). The manner of the combination of the chrominance components is changed on an 8-field cycle. In an alternative arrangement, if the PAL signal is originally stored in a store which provides outputs from more than one line simultaneously, two stored lines can be combined, and the chrominance portion of the thus-combined signal combined with the luminance portion of a stored signal to provide the output. <IMAGE>

Title: Electronic Signalling Device for Connection to a Signal Transmission Line
IPC: H04M19/08
Filed: 1979-09-17
Abstract: Electronic signalling device for connection to a signal transmission line by means of which the device is supplied with a DC-supply current. The device comprises a plurality of circuit units each of which must be supplied with a DC-supply current. Feeding the circuit units in series has the advantage that the DC-supply current in each of the circuit units can be utilized to the full. A drawback is that the different supply voltages add up. A practical requirement may be that the total supply voltage does not exceed a certain value at a certain value of the supply current. In order to satisfy this requirement means are present which cause the supply voltage of one of the circuit units to decrease more than proportionally to the DC supply current when the DC- supply current decreases to below a certain value. The invention is suitable for use in loudspeaking telephone sets.
