Abstract: In a television receiver, a colour picture tube (16) for displaying a colour picture has a signal supply that includes a plurality of primary colour signal channels for supplying a plurality of primary colour signals to the tube (16) and current detecting means (26) connected to the signal supply so as to detect currents flowing through the tube (16) and an automatic white balance circuit (23, 24, 8, 10) for controlling the signal supply in response to the detected currents detected by the current detecting means (26). A power responsive circuit (321) generates a control signal when a power switch for the television receiver is turned on and a blanking circuit (22) connected to the signal supply inhibits the supply of primary colour signals to the tube (16). A first circuit (322) connected to the power responsive circuit (321) actuates the blanking circuit (22) when the power switch is turned on, and a second circuit (323) connected to the current detecting mens (321) deactuates the blanking circuit (22) when the current which flows through the tube (16) exceeds a predetermined value.

Abstract: A process is disclosed for the formation of hydraulic binders and building elements comprising from 70% ettringite and up to 30% calcium silicate hydrates. Ettringite is a very strong mineral and the product may be at least the equal in terms of mechanical properties of Portland cement while suffering shrinkage and expansion problems. The process comprises mixing powdered source materials of reactive CaS0 4 , CaO and Al 2 O 3  with or without Si0 2  and hydrating the intimate mixture at a ratio in the range of I part powdered source materials to 0.35-i part water. Most conveniently, impure source materials such as industrial by-products are used as they have been found to catalyse the hydration reaction. Further if gypsum is a powdered source material, in a natural, pure or chemical form, it is preferably calcined since such material sets quickly and gives early mechanical strength. A clinker of calcium sulphoaluminate may be produced for use as a powdered source material.

Abstract: A globular food product formed of a piece of solid state food material S and a wrapping of a food material P having a clay-like consistency is produced by passing the material P from a hopper 13 to a cavity 23 using a screw-type extruder 11. The material P forms an even layer over a gate 3 having an openable mouth. Pieces of the material S are metered from a hopper 4 to a vertical cylinder 22 via a piston 43b and cylinder 43a. An ejection piston 51 operates in cylinder 22 to urge the material S against the layer of material P in the cavity 23 as the mouth of the gate 3 opens. The material S becomes wrapped in the material P and is ejected from the gate 3 whose mouth then closes to cut the material P so as to form the globular shape.

Abstract: In a resonant degaussing circuit for a television display apparatus an auxiliary current is supplied to the resonating capacitor, during a portion of at least one cycle of the degaussing current, to augment the charge stored by the capacitor and thereby lengthen the degaussing interval. In a particular embodiment, first (C1) and second (C2) capacitors are charged prior to a degaussing interval. A first switch (SCR1) couples the first capacitor (C1) to a degaussing coil (L DG ) to initiate the degaussing interval. The first capacitor (C1) and the degaussing coil L DG  form a resonant circuit that resonates to generate a decaying alternating degaussing current. During a predetermined portion of each cycle of the degaussing current, a second switch (Q4) couples a precharged second capacitor (C2) in parallel with the first capacitor (C1) to form a charge transfer arrangement that transfers charge from the second (C2) to the first (C1) capacitor for replenishing energy losses in the first capacitor (C1). The charge transfer arrangement increases the duration of the time it takes for the amplitude of the degaussing current to decay and, hence, the length of the degaussing interval.

Abstract: A bit-error-rate tester provides for testing of links with different numbers of channels without replacing or reconfiguring an included pseudorandom word sequence (PRWS) generator. The tester includes a transmitter (11) and a receiver (21), each with generators (12, 22) for parallel evenly staggered pseudorandom bit sequence (PRBS) replicas collectively constituting the PRWS. The receiver generator (22) is a copy of the transmitter generator (12) so that it can predict the PRWS received from the transmitter. Comparators (C1-C4) are provided so that incoming and locally generating sequences can be compared to determine bit error rates. Synchronization of the receiver generator is effected using a pattern detector coupled to at least one reception line. When a predetermined pattern is detected, an injector injects registers of the receiver generator with a predetermined bit pattern. Afterwards, the receiver generator (22) autonomously generates its PRWS synchronously with the PRWS received from the transmitting generator (12). A further embodiment provides for rerouting of crossed transmission channels as well as synchronization. In either case, there is no requirement that all available channels be active to effect synchronization.
