Patent GB-1294095-A (GB)
Title: Improvements in or relating to a device for recording and timing events
Inventor: LUMBER ARTHUR LESLIE
IPC: H04M3/12
Filed: 1968-12-24
Abstract: 1294095 Exchange systems; semi-conductor switching circuits POST OFFICE 17 March 1970 [24 Dec 1968] 61431/68 Headings H3T and H4K [Also in Division G4] Monitoring apparatus comprises means arranged to indicate the beginning and ending of each of a sequence of events, means arranged to count the indicated events, means arranged to increment a counter for every nth indicated event and means arranged to time the duration of one event in every group of n. The circuit shown is used to accumulate data relating to the waiting time of calls established through a manual switchboard. The majority of the circuitry shown (i.e. that to the left of the multipling) is provided in multiple each set being associated with a different lamp relay of the switchboard. An incoming call causes contact B1 toclose energizing lamp relay LR. The resultant positive signal is absorbed by diode D1 and the negative signal (if of sufficient duration to pass through a filter comprising capacitors C 1  and C 2  and resistor R2) turns on a transistor TR1. The positive going pulse produced at the collector of this transistor, integrated and lengthened by a capacitor C4 and a resistor R5 is passed by a diode D3 and after shaping is fed to a first counter which counts the total number of calls and to a second counter which steps up to n then steps to zero incrementing a further counter by one and triggering a uniselector drive circuit for each cycle of n counts. Said positive going pulse is also applied to a normally charged capacitor C3 partially discharging the same. The capacitor commences to re-charge and marks a fixed contact in one bank of the uniselector the mark decaying exponentially as the capacitor re-charges. Other contacts in other banks may be independently marked by the circuitry associated with other lamp relays. Every nth call the second counter pulses a silicon controlled rectifier CSR2 switching it to conduction turning on a relay ST which it manitains. Contact ST1 energizes the uniselector drive and the uniselector steps until it finds a marked contact. When a wiper of the uniselector detects a marking above the threshold set by R6 and R7 a transistor TR2 is blocked switching to conduction TR3 which in turn switches on silicon controlled rectifier CSR1, transistors TR6, TR5 and TR7 energizing a relay HS. If more than one wiper simultaneously detects a marking above the set thresholds highest priority banks as determined by higher to lower priority diode connections D12 is selected. The energized relay HS starts a timer, shorts CSR2 and maintains ST. When the lamp relay is de-energized by S1 a negative going pulse from TR1 switches TR4 to conduction turning off TR5, TR7 and HS turning- off the timer.

Title: Suspended Platform
IPC: E04G3/24
Filed: 1978-08-03
Abstract: A suspendable climbing platform has a number of decks (3) which project from a parallelogram-linkage framework to contact a wall to which access is required. The angle of the parallelogram linkage can be altered as the angle of the wall alters so that the decks are always parallel and horizontal. Since the decks project from the framework, the framework is kept at a distance away from the wall, and there is no vertical obstruction on the wall. A clear working space is thus left. The parallelogram linkage can be fixed in any desired position, so that the decks are stable. <IMAGE>

Title: Manufacture of elongate optical fibre waveguide structures
IPC: G02B6/44
Filed: 1979-01-25
Abstract: In the manufacture of an optical fibre cable, or a unit for incorporation in a cable, consisting of one or more optical fibres surrounded by a loosely fitting tube, by extruding the tube around the fibre or fibres and winding the assembly on to a drum, longitudinal relaxation of the fibre or fibres within the tube is achieved by rotating a drum on which the assembly is wound, while at least one end of the fibre or each fibre has freedom of movement. Relaxation of the fibres occurs as a result of oscillation and slippage of the fibres within the tube, causing the fibres to retract from the free end or ends of the tube: to enable slippage to take place, the friction between the fibres and tube must be low, and the drum is rotated slowly.

Patent GB-2068687-A (GB)
Title: Digital synchronising system
IPC: G11B5/09
Filed: 1980-01-09
Abstract: A synchronizing system for the control of the transmission of digital information which is composed of blocks separated by gaps and for which synchronization requires the production of a reference pulse. Each field of information includes a series of spaced coded synchronizing control words each of which is a coded representation of the separation between the word and the position required for the synchronizing signal. The synchronizer (FIG. 3) includes a decoder composed of read-only memories (IC2, IC3) which can set a counter (IC4, IC5 and IC6) in accordance with the separation. The decoded synchronizing control signal is compared by comparator IC8 and a read-only memory IC7 with the instantaneous contents of the counter and the counter is adjusted only if parity is not detected. If parity is detected and continues to be detected for each synchronizing control word, the counter counts towards a datum whereupon the synchronizing signal is produced. The occasions of parity are counted by another counter which causes the production of an inhibiting signal for the output synchronizing signal unless a predetermined number of occasions of parity are counted.
