Patent GB-2013344-A (GB)
Title: Ultrasonic flaw detection
IPC: G01N29/34
Filed: 1979-01-29
Abstract: In a dry-coupling transmission system transmitter and receiver probes (10, 12) carry contact pads (18) of a material soft enough to give good acoustic coupling to the material under test but which undergoes substantially no compressive distortion under load (polyvinyl chloride, for example). The contact pads may be rollers. The transmitter probe (10) comprises an undamped crystal which is driven to produce a spectrum of frequencies and a resonant frequency from this spectrum is selectively amplified using a discriminator (20) to determine defects in the test object (16). Changes in the amplitude and displacement of the received signal are used to indicate flaws. The beam from the transmitter probe has a uniform cross-section for the whole of its path through the test object. Thus, one can test laminated joints, bonded materials, brazed joints, rubber composite materials and friction materials. <IMAGE>

Title: Method for transmitting information from above ground to a pit cage and vice versa
IPC: H04B5/02
Filed: 1979-02-13
Abstract: For communication between a sending and receiving instrument above ground (5) and a like instrument (6) in a pit cage, the information is transmitted at such a high carrier frequency that the transmission circuit formed by the lifting cable earthed above ground and the earth capacity of the pit cage has a sufficiently low ohmic resistance to ensure that the receiving instrument always receives the information. Transmission is at a carrier frequency, at which the inductance of the lifting cable and the earth capacity of the pit cage form a series resonance circuit, or substantially lower than the quotient of the velocity of light divided by twice the depth of the shaft. <IMAGE>

Title: Gas separation processes
IPC: C07C67/00
Filed: 1979-03-19
Abstract: In separating gas(es) from a gaseous mixture using at least two permeator stages, the feed sides of which are in series, each stage containing a separation membrane which exhibits selective permeation of the gas(es) and a pressure differential being maintained across each membrane, the ratio of total pressure on the feed side to total pressure on the permeate exit side of the membrane for at least one permeator stage is less than the corresponding ratio for at least one subsequent permeator stage. The process may be employed to treat an ammonia synthesis purge stream (30) from an ammonia synthesis loop (20 to 28). The membranes in the permeators (36, 42) are selective to the permeation of hydrogen as compared to inert contaminants such as methane and argon. The permeates from the first and second permeator stages are recycled (38, 44) to the ammonia synthesis feed 10 downstream and upstream, respectively of a compassion stage (12) thereof. Alternatively, the second stage recycle stream may be compressed and mixed with the first stage recycle stream. <IMAGE>

Title: Queuing controller
IPC: G06F3/02
Filed: 1980-01-10
Abstract: A queuing controller stores strings of data and transmits them to a computer when required. The controller 1 is coupled to receive data passing between the computer and its operator's terminal and receives and transmits data from and to the computer via serial/parallel input/output device 11. The controller has a keypad 2 coupled to the rest of the device via a wire or ultrasonic link. A keypress queue store 6 stores codes corresponding to the keystrokes and accesses a store 7 containing initial addresses of associated data stored in a main memory 8. Memory 8 may contain permanently stored data or may be loaded from the computer. The controller can supply to the computer instructions and data normally supplied via the operator's terminal and can for example search for a string of data received from the computer and supply a response thereto or issue an audible bleep when operator intervention is required. <IMAGE>
Patent GB-2051139-A (GB)
Title: Reactive dyeing and printing of cellulose
IPC: C09B62/04
Filed: 1980-02-07
Abstract: Process for the colouration of cellulose textile materials which comprises applying a dyestuff containing one or more s-triazinyl groups bearing a quaternary nitrogen substituent, or the precursors of such a dyestuff, in the absence of an acid- binding agent and heating the treated textile material to 150 DEG C or higher to fix the dyestuff to the cellulose. Improved colouration is often achieved by applying urea or dicyandiamide with the dyestuff. The process is particularly valuable for the colouration of cellulose in polyester/cellulose unions when a disperse dye may be applied simultaneously with less problems than encountered with conventional alkali fixed reactive dyes.

Patent GB-2050100-A (GB)
Title: Integrated output amplifier stage
IPC: H03F3/20
Filed: 1980-05-02
Abstract: An integrated amplifier output stage is of the kind in which a pair of output transistors (T1, T2) connected across a power supply drive an output terminal (1) in push-pull when a signal is applied to an input terminal (4). The output transistors are biased by means of a biasing circuit (D3, D4, D5) fed from a constant current source (5, D6, T6, T7). In order that the output current (I0) of the current source can be chosen just sufficient to fully drive the first output transistor (T1) when the voltage at its emitter becomes limited by the supply voltage (+ VB), thereby reducing the high-frequency distortion produced when this situation occurs, the current gain from the current source to the first output transistor (T1) is made independent of the current gain of the first transistor by including a diode-connected transistor (D1) in parallel with the base-emitter junction of the first transistor. The maximum current fed to the base of the first transistor (T1) is made independent of the current gain of a driver transistor (T3) by constructing a resistor (5) included in the current source as a buried resistor having the same structure as the base region of the driver transistor (T3). As an alternative to the buried resistor 5 a further diode-connected transistor (not shown) may be included across the base-emitter junction of the driver transistor (T3). As a further alternative the driver transistor (T3) and the transistor structure (D1) may be omitted and the base of the first transistor (T1) may be connected directly to the output of the current source. <IMAGE>

Title: Railway vehicle braking system
IPC: B61H1/00
Filed: 1980-06-20
Abstract: A braking system for railway vehicles of simplified construction having fewer parts than known systems includes a crossbar (40, 40') suspended from the vehicle body on each side of an axle, e.g. by tie-rods (42, 42'). A friction brake pad (46, 46'), is mounted at each end of each crossbar for engagement with a wheel rim. One crossbar (40') is linked to a first cranked lever (54) which is also connected to the vehicle and to a second lever (30). The second lever is connected to the other crossbar (40) and to a brake application rod (26). Movement of rod (26) causes the crossbars (40, 40') to move closer together to apply the brakes. The brake force applied by each crossbar is equalised by choice of the dimensions between the pivot points of the mechanism. <IMAGE>
