Patent GB-2036999-A (GB)
Title: Optical probe
IPC: G01J5/04
Filed: 1979-11-14
Abstract: An optical probe (25) e.g. in a radiation pyrometer, for measurement of temperatures of blades (1) in a gas turbine has the objective end (39) of the probe (25) flush with the outer wall (13) of the turbine gas passage in order to avoid disturbance of the gas flow (5) and is thus angled away from the blade (1). The probe has an objective prism (31 ), e.g. of sapphire, whose front and rear faces (39, 40) are inclined with respect to each other, so that for rays of a preselected wavelength, the prism refracts into the probe only those rays from a preselected location (A) on the blade. A filter passes radiation at a single wavelength, and therefore a single image from the single preselected location (A) on the blade (1). An image centralising prism (33) realigns the optical path within the probe. <IMAGE>

Patent GB-2042956-A (GB)
Title: Method of Igniting a Direct current Welding Arc
IPC: B23K9/167
Filed: 1980-02-06
Abstract: In DC, straight polarity, arc welding, proper ignition of the arc at the beginning of the welding process is achieved by reversing the polarity of the electrode and of the workpiece for a short period, and with the electrode and workpiece connected respectively to the positive and negative poles of the power source, supplying an ignition pulse between the electrode and the workpiece. As shown, a power source 10 is connected via a pole-reversing switch 13 to an electrode 14 and workpiece 15. Pulses from the power source 10 reverse the polarity of switch 13 for a period, of less than one second, determined by a timing relay 17, and during this period power is supplied to an ignition unit 16 which ignites the arc. The method has particular application to fully mechanised welding of light alloys, such as aluminum; in an inert-gas atmosphere (e.g. He or He/A) with a non-consumable electrode. <IMAGE>
Patent GB-2046379-A (GB)
Title: Improvements in drum brake automatic adjusters
IPC: F16D65/56
Filed: 1980-03-06
Abstract: The invention provides means whereby a drum brake automatic adjuster only operates from time to time, rendering the adjuster less sensitive to sudden changes, as occur due to thermal expansion or mechanical deflection of the drum. An eccentric cam wheel (14), placed alongside the adjuster nut (13) on a rod (12) moves the pawl (27) in and out radially relative to the nut, only allowing it to engage the nut periodically. The wheel has ratchet teeth, like the nut, and is also rotated by the pawl - nut (13) is threaded on rod (12) whilst wheel (14) is rotatably mounted on but not threaded to the rod (12). A tag (28) prevents the adjuster operating at all as the linings become worn out. <IMAGE>

Patent GB-2057528-A (GB)
Title: Absorbent paper
IPC: D21F11/14
Filed: 1980-08-27
Abstract: Hitherto, paper webs for absorbent paper products have been creped either when wet which gives the web bulk but results in a stiff and uncomfortable hand, or when dry, which creates a softer web but one lacking in bulk and absorbency. The process of the invention includes the steps of creping the web when wet, i.e. when it has above 50% moisture content, subsequently drying the web to at least 80% dry and then re- creping the previously wet creped web, in this dry state. This produces a web which is both bulky and soft, having a finished basis weight of from 30-60 gm/m<2>.
Patent GB-2066627-A (GB)
Title: P.C.M. frame aligner with frame slip characteristic
IPC: H04J3/06
Filed: 1980-11-27
Abstract: The propagation delays in aligners for digital switching systems are becoming a matter of growing concern as increased switch transmission delay is contemplated in the future digital switching system designs employing more than two stages of time switch. A current design involves a 21 DIVIDED 2 frame delay which will be unacceptable in the new design. This proposal involves updating the one frame aligner of the type disclosed in B.P. 1,498,498 so that the read/write counters of the aligner remain separated regardless of the state of synchronisation of the line served by the aligner. The circuit details ensure that either there is no slip between the frames or there is one complete frame slip which is either a frame repeated or a frame lost. In this present proposal when comparator logic detects that the count of the write counter is catching that of the read counter, the read counter is advanced by x-bits, a shift register is inserted in the data path to the time switch and double read is effected on the buffer store of the aligner for x-bits.

Patent GB-2082780-A (GB)
Title: Electro-physical Measuring with Variable Resistance Transducers
IPC: G01K17/08
Filed: 1981-08-25
Abstract: By using a dual slope integrator for determining the ratio of a variable transducer resistance 1 (e.g. a temperature dependent resistor or diode) to a single reference resistor 3 connected in series therewith, the disadvantages of known measuring bridge circuits where numerous essential resistances etc lead to errors according to fluctuating ambient temperature, ageing effects and production tolerances are avoided insofar as only tolerance values of the single resistor 3 come into the matter. The series connected resistors are fed a controlled current via lines 63, 64 and the ratio of the voltages across them is determined by operating switches 101 and 103 in turn whereby to charge and discharge capacitor 27 of integrator 7 at rates determined respectively by the voltages across resistor 1 and 3, charge being for a predetermined number of clock pulses; during the discharge and until the capacitor falls to a reference voltage, comparator 9 enables clock pulses to be counted. For measuring temperature differences, different transducers are connected in turn in series with the same resistor 3. Non-linear charges of resistance with temperature are compensated by inverter 10 and associated elements 43-5 and 110. <IMAGE>
