Title: Displacement Transducer
IPC: G01B7/24
Filed: 1980-05-15
Abstract: In a displacement transducer, displacement of a magnetic fluid 107 moveable in a cavity 108 is used to produce an output signal. The displacement can be the result of movement of diaphragms 103, 104, in a differential pressure cell. In a force-balance transducer, the magnetic fluid has a balancing force applied to it magnetically so as to keep it substantially stationary within the cavity. Means are provided for producing an output signal dependent on either the magnetically detected position of the magnetic fluid or on the magnitude of the balancing force, as appropriate. <IMAGE>
Patent GB-2063620-A (GB)
Title: Channel zero switching arrangements for digital telecommunication exchanges
IPC: H04Q11/04
Filed: 1980-07-26
Abstract: It is an emerging international telecommunications requirement that all 32 channels of the p.c.m. multiplex must be switchable. The switching of channel zero relates to the "spare bits" not defined for synchronisation purposes and these bits may be used as a data-bearer for network administration or control purposes. Digital telecommunication switching networks, therefore, must be capable of concentrating channel assemblies of these spare bits into one transmit multiplex which may be connected to a spare bit data processor remote from the switching network or co- located with it. The passing of channel zero into the switch block, however, is dangerous because if this data is passed across the switch block to another digital line termination unit DLT in a time slot other than channel zero then that receiving DLT will be called upon to transmit data containing two valid sets of sync and non-sync patterns which could confuse the synchronisation circuits associated with the digital transmission system connected to that DLT. Such an arrangement is prevented using equipment in the receive and transmit DLT's. In the receive DLT after the incoming synchronisation channel has fulfilled its synchronisation purpose it is deliberately modified such that when switched to a transmit multiplex it will not be erroneously recognised as a sync channel. The modification does not of course cause loss of information contained in the spare bits or alarm bit. At the transmit DLT a decision is made as to whether the international bit in the sync pattern and the international bit and spare bits in the non- sync pattern should be transmitted to line as data ones or the patterns received.

Title: Improvements to tufting machines
IPC: D05C15/14
Filed: 1980-12-09
Abstract: A low-cut pile tufting machine having needle plate backing support fingers (18) oscillated in timed relationship with the hooks (20) and the needles (12) of the machine to support the backing material (14) during needle penetration which withdraws from the needle path as the hooks move across the needle path to seize loops. The needle plate ( 16) is mounted on a rocker arm (54) carried by a common rock shaft (40) with the rocker arm (38) on which the hooks (20) are mounted so that the needle plate (16) together with the fingers (18) oscillate in opposition to the oscillation of the hooks (20). As the hooks (20) move toward the plane of reciprocation of the needles the fingers (18) move away from such plane and vice versa. <IMAGE>
Patent GB-2092753-A (GB)
Title: Contour Measuring Instrument
IPC: G01B7/28
Filed: 1981-02-05
Abstract: An instrument for measuring the contour of the outer surface of a workpiece 23 has a stylus 22 secured at one end of a counterweight arm (6) which is pivoted about an axis (33) so that the stylus rests in contact with the workpiece. The arm is moved in the longitudinal direction thereof, and the vertical displacement of the stylus, tracing the irregularities of the outer surface of the workpiece, is measured by a differential transformer (69). The arm (6) consists of two parts (18, 20) which are urged to a relative position by means of springs (29, 30). A mechanism (39) detects relative movement between the arms so that when a force exceeding a predetermined value applied to the stylus is detected the movement of the arms is stopped. The fulcrum (33) for the arm is movable in the longitudinal direction of the arm and a pivotal connecting link (78) is connected to the arm, so that errors in circular arcs of the stylus due to the rotational movement of the arm can be corrected. <IMAGE>

Title: Removal of Residual Catalyst from Polyolefin Polymers
IPC: C08F6/02
Filed: 1981-02-24
Abstract: An improved method for reducing the halogen content of a particulate polyolefin formed by catalytic polymerization of an olefin in the presence of a Ziegler-Natta catalyst comprises the steps of causing the polyolefin in the dry state to flow into a gas phase fluidized bed, contacting the polyolefin in the fluidized bed with a gas comprising 0.05% to 0.2% alkylene oxide, 5% to 30% water, and the balance inert gas such that the alkylene oxide reacts with halogens present in the polyolefin to form an alkylene halohydrin, removing the alkylene halohydrin from the fluidized bed and thus reducing the halogen content of the polyolefin. The improvement comprises regenerating the alkylene oxide by contacting the inert gas containing alkylene halohydrin with a caustic solution in alcohol or water and recovering therefrom alkylene oxide formed by the reaction of the alkylene halohydrin and the caustic solution.

Patent GB-2079105-A (GB)
Title: A pulse width modulation system
IPC: H03F3/24
Filed: 1981-02-27
Abstract: In P.W.M. circuits for supplying amplitude modulated current to the anode of the R.F. stage of a high power radio transmitter, problems arise from carrier compression and from the need to protect the voltage source against excessive currents in the event of one or both of the switching valves breaking down. The protection circuit needs to handle an extremely large power: namely all the power supplied to the anode. The invention overcomes this problem by using two voltage sources one of which provides carrier power whilst the other drives a pulse width modulation amplifier which modulates the carrier. Varying demand for power to the amplifier thus does not affect the carrier. Therefore carrier compression is reduced. Also, only that voltage source which feeds the amplifier needs a sophisticated fast acting protection system and since this does not supply all the power to the anode the protection system is able to operate reliably.
