Patent GB-653963-A (GB)
Abstract: 653,963. Knitting machines. TOONE (NOTTINGHAM), Ltd., B., and ALLEN, T. L. Jan. 21, 1948, No. 1902. [Class 74 (ii)] A stop-motion mechanism for shifting the driving-belt of a circular machine from a fast to a loose pulley comprises cam means rendered inoperable or operable on a lever operating the belt fork, by a stop-motion actuating device. A fault causes a bell-crank lever 3 to be pulled round by the lip 2 of a member 1 connected to the fault detector. This releases a doublearmed lever 10, the lower arm 13 of which is moved by a spring 12 to rotate a pivoted catch 15, so moving a truck 18 into the path of a cam 28 carried on a driven pulley 24. The cam causes rotation of a lever 16 to which the catch 15 is pivoted, the lever 16 shifting the belt fork 21 to carry the belt to the loose pulley 25. A lever 30 engages the fork 21 to hold it in the non-driving position against the action of a spring. Hand release of the lever 30 permits the fork 21 to return with resetting of members 16 and 15. Lever mechanism 33 operated from the pattern chain 34 may render the device inoperative. A second driving pulley 26 maybe fitted and a handle 32 may permit manual operation of the fork 21. Additional members 1 may be fitted. Specification 642,154 is referred to.

Patent GB-2022193-A (GB)
Title: Pulse damper
IPC: B01D15/08
Filed: 1979-02-27
Abstract: A pulse damper for use in high- pressure liquid pumping applications such as liquid chromatography comprises a length of flattened polytetrafluoroethylene tubing 10 that can be coupled to the high-pressure liquid flow line. The flattened tubing is enclosed within a liquid-tight housing structure 20 filled with a compressible liquid 30, and the ends of the tubing are coupled to the high-pressure flow line by fittings 23, 24 mounted inside the housing structure. When a transient pressure variation occurs in the flow line, the cross-section of the tubing changes from a flattened elliptical configuration to a more rounded configuration as the pressure pulse temporarily overcomes the stresses that tend to maintain the tubing in its flattened configuration. The restoring force of the compressible liquid in the housing structure surrounding the tubing prevents expansion of the tubing beyond a desired limit during a pulse, so that the tubing cannot burst when its cross-sectional configuration changes. <IMAGE>

Title: Printing machines
IPC: B41F13/00
Filed: 1979-04-18
Abstract: A printing machine for printing on individual articles such as plastics bags has a rotatable printing roller 1 to which articles are fed one at a time. Rotation of the roller 1 is automatically initiated when an article approaches the roller, as detected by a sensor 27, and the roller 1 stops after it has rotated through a predetermined angle. Feed rollers 7, 16 and 19 may be continuously driven. The printing roller 1 may stop after a single revolution, either as a result of a projection, preferably adjustable, on the roller 1 cooperating with a switch, or by a timer in the control circuitry. <IMAGE>

Patent GB-2023798-A (GB)
Title: Fin-tube heat exchanger
IPC: F28F1/32
Filed: 1979-06-20
Abstract: A cross-fin tube type heat exchanger having a large number of parallel fins and a plurality of heat transfer tubes extended through and fixed to the fins, so that heat may be exchanged between a first heat exchanging medium flowing through the heat transfer tubes and a second heat exchanging medium flowing along the surfaces of the fin, across the walls of the heat transfer tubes and through the fins. In the portions of each fin between adjacent heat transfer tubes of the same row, formed are a number of slits perpendicular to the direction of flow of the second heat exchanging medium. Each elongated section defined between each pair of adjacent slits is bent along its breadthwise bisector line and is raised in the form of a bridge to constitute an upwardly convexed louver element. The upwardly convexed louver element may have a cross section with an obtuse apex angle, or may have an arcuate cross section. The successive louver elements are arrayed in the direction of flow of the second heat exchanging medium in a manner of corrugation, or alternately staggered in the heightwise direction so that the edges of adjacent louver elements may be staggered in the heightwise direction. The fins having louver elements thus constructed cause a turbulency of the flow of the second heat exchanging medium to effectively prevent boundary layers of the latter from growing, thereby to ensure a higher efficiency of the heat exchange. Also increased stiffness or rigidity of the fin is obtained thanks to the provision of upwardly convexed louver elements.

Patent GB-2065376-A (GB)
Title: Space diversity antenna
IPC: H01Q3/26
Filed: 1979-12-10
Abstract: By feeding microwave energy to ports 13 or 14 the phase of the energy at horn 17 can be made to lead or lag that at horn 18 as desired. If it leads, the transmitted beam squints upwardly onto the top half of an offset parabolic reflector 1 so as to produce a parallel transmitted beam at a relatively high level defined between lines 8 and 11. Conversely, if the phase at horn 17 lags that at 18 the beam squints downwardly and is reflected from part 6 of the reflector 1 to be transmitted at a relatively low level between lines 7 and 8. In this way a single transmitter, feed device 5 and reflector 1 can be used to obtain height diversity. This contrasts with previous proposals in which completely separate systems have been needed to achieve the height diversity. The illustrated system also operates as a receiver. <IMAGE>
Patent GB-2066520-A (GB)
Title: Control circuit
IPC: G05D23/20
Filed: 1979-12-21
Abstract: The energisation of a heating element 1 is controlled in dependence upon a comparison of an actual-value signal (from a sensor 2) and a signal which is the sum of a set-value signal (from a reference source 8) and the output of a fixed-frequency triangle wave generator 6 which is amplitude modulated in dependence upon the rate of change of temperature. The effect is to produce a proportioning range (within which the mean power to the heater 1 is proportional to the error between the actual and set values) which is dependent upon the rate of change of temperature and which is therefore reduced as the set value is approached. The circuit produces good dynamic performance without instability, and may be used in applications other than temperature control, e.g. a servo system. <IMAGE>
Patent GB-2070666-A (GB)
Title: Props
IPC: E21D15/16
Filed: 1980-03-04
Abstract: A prop has upper and lower hollow tubes 10, 11 which fit together telescopically and which are sealed at 12. There is a low level inlet 17 to the lower tube 11 and a high level air vent 16 from the upper tube 10. In use, hydraulic cement grout 21 is introduced under pressure into the legs through the inlet whilst air is expelled from the vent. When the legs are full the vent is closed and the assembly expands upwardly under the influence of the pressurized liquid until a platform 19 engages the overlying structure. The liquid then sets to form a rigid support. One embodiment includes rubber compression pods 21 mounted beneath the platform 19. <IMAGE>

Patent GB-2054515-A (GB)
Title: Liquid container with straw
IPC: B31B1/90
Filed: 1980-07-17
Abstract: Apparatus forms a liquid-tight container having a rectangular cross- section from a one-piece, T-shaped blank (100) of paperboard. The apparatus automatically bonds a polythene panel and straw 220 to the carton blank on a rotating vacuum-hold heat-sealing and alignment drum (146). A conveyor collates carton blanks with four side-by- side forming mandrels (only one of which is shown at 304 in Figure 26). An ultrasonic welder bonds the side seams and end closure panels of each of four containers on side-by-side rotating crossbar mandrels (400) which eliminate any misalignment during the sealing process. A conveyor then carries the carton blanks through pre-form (see Figure 51a), two-stage filler, and end- closure work stations, including anvils for ultrasonic welding. An ejector mechanism ejects the filled carton blanks from the rigid conveyor along a dual direction path, thereby eliminating the possibility of creasing or puncturing the filled and sealed container. The apparatus accommodates the production of differing size containers with five adjustments. <IMAGE>
