A generally spherical pipeline cleaning "pig" 1 is formed of a resiliently deformable material, such as natural or synthetic rubber, and is provided with a plurality of discrete, discontinuous, and laterally-spaced-apart protuberances 12 which have a hardness greater than that of the "pig" material. The "pig" may be a solid or hollow and may be formed of "soft", "semi-hard" or "hard" rubber. Rubbers which may be selected for their respective hardnesses are: natural rubber; butadiene-styrene copolymers; butadiene-acrylonitrile copolymers; polychloroprenes &c. The protruberances 12, which may be formed of the same material (chemically) as the "pig" body but having the necessary degree of hardness, may be provided with hard metal tips. Alternatively, the protruberances may comprise tungsten carbide studs embedded in holes drilled in the "pig" body. To clean a pipeline a first "pig" is injected into the pipeline by conventional means and propelled along the pipeline and, after an interval of time a second "pig" is similarly injected.

Abstract: 1,259,328. Percussive tools. GARDNERDENVER CO. 6 Oct., 1969 [16 June, 1969], No. 49025/69. Heading B4C. A percussive tool comprises a hammer piston 16 reciprocable in a cylinder 12, a distributing valve 24 for alternately directing pressure fluid supplied via pipe 28 into chambers 56, 80, and a throttle for reducing the flow of fluid to the distributing valve actuable in response to fluid in chamber 56 reaching a predetermined pressure. When this pressure is reached, i.e. when tool bit 52 is subject to a " no-load " condition, check valve 60 will be opened to permit the fluid to flow into chamber 72 and thus move throttle member 74 to throttle the flow of fluid via passages 30, 32, 34. In an alternative embodiment (Fig. 2, not shown), the fluid from chamber (56) when the predetermined pressure is reached, flows past a check valve (92) and actuates a valve (96) to connect chamber (98) housing the throttle member (102) to a source of pressure fluid. In the inoperative condition of the valve (96) the chamber (98) is connected to atmosphere.

An automatic control system has an indicating meter energized by an error voltage and a pointer 20 movable in either direction from a rest position over a movable calibrated scale plate which is mechanically coupled to the wiper 27 of a set point potentiometer 24, the wiper being connected to a condition sensing sensitive voltage element such as a thermocouple 12. A mark 32 indicates the position of the wiper 27 and in the embodiment described the scale 31 is calibrated in degrees of temperature. The thermocouple voltage is applied in series with a set voltage from the potentiometer to a constant gain amplifier the output of which controls a heater 11 through a relay 15, 16. The amplifier 18 output is also fed to the meter movement 19. In a practical application the wiper 27 is coupled to the scale and in a modification Fig. 4 (not shown) a multi-turn potentiometer (80) is coupled to the scale moving member through annular step-up gearing (84). The temperature range may be varied by substituting a manually controlled variable gain amplifier and the meter may have a zero in other than the central position. The scale plate may form an outer surface of the meter housing so that the plate is at all times visible. The scale plate may be transparent and overlie the pointer. The thermocouple may be replaced by a condition responsive bridge network.

In a machine for recovering tobacco from imperfect cigarettes, in which the cigarettes are fed to an opening mechanism and the tobacco subsequently separated for further use, means are provided to divert any unattached tips before they reach the opening mechanism. Cigarettes are fed to the opening mechanism along grooves 15 in the members 11, 12, 13 of an inclined, vibratory conveyor, and any unattached tips that are present fall through a gap 17 between the members 12, 13. Wires 16 spanning the gap prevent any cigarettes that are oriented transversely to the grooves from falling through the gap. After the cigarettes have been opened and subjected to the action of a heater they are dropped onto a vibratory sieve which passes the tobacco. The tips that have fallen through the gap 17 may also be fed to the sieve for the recovery of any tobacco mixed with them. Any loose tobacco on the member 11 falls through slots 19 and is directed on to the sieve.

Abstract: 1310509 Multiplex pulse code signalling PLESSEY TELECOMMUNICATIONS RESEARCH Ltd 2 Sept 1970 [6 June 1969] 28745/69 Heading H4L In a multiplex electrical signalling system in which the message signals in digital form are modulated to indicate the information to be transmitted and the address of the destination, the message signal A is of bipolar form and the six digit address signal B is also of bipolar form and is repeated sequentially. These signals are combined as at C so that the message signals are amplitude modulated by the address signals. A plurality of such signals can be transmitted in a conventional time division multiplex system, a common timing signal being fed to the various transmitters to synchronize the transmission of the addresses. The receiver determines the magnitude of each received digit and subtracts the magnitude of an unmodulated signal digit resulting in the detection of the corresponding address digit. A set of low pass filters comprising one filter for each digit of the address is provided for each channel, the impulse response of each filter being a positive pulse having a duration of at least 100 times the repetition period of the address. The output of each filter is compared with positive and negative threshold levels each of half the magnitude of the corresponding maximum signal and if the output signal has a value outside the range between the threshold values an address digit is considered to be detected, a negative output representing 1 and a positive output 0. If a digit has been absent for a period somewhat greater than the impulse response period, approximately fifty consecutive appearances of the digit will cause it to be detected as present and the disappearance of the digit for about fifty consecutive address periods will cause it to be detected as absent. The address is treated as detected when at least all but one of the address digits is detected at the receiver. Preferably the address code is arranged to have an equal number of 1's and 0's.
