Abstract: Method and apparatus for the manufacture of cigarette filters containing particulate material. Filter material composed of cellulose acetate tow is fed in the axial direction through a gap defined between a first pair of rolls so that the transverse cross-section of the filter material is changed to a substantially oval shape. The filter material is then feed through another gap defined between a second pair of rolls so that the transverse cross-section of the filter material is further changed to a substantially heart shape and at the same time providing pockets at axially spaced positions. Particulate material is deposited in said pockets. The filter material is closed so that the deposited particulate material is positioned in the interior of the filter material and wrapped with wrapping sheets. <IMAGE>

Title: Improvements in Plug and Socket Electrical Connector Assemblies
IPC: H01R24/00
Filed: 1979-11-27
Abstract: An electrical connector assembly includes a first housing (12) with terminals therein, and a second housing (16) receivable within the first housing with terminals therein adapted to mate with the terminals at the first housing. Both housings are relatively movable in the first direction with respect to one another between an initial position (Fig. 4) wherein the second housing is initially received in the first housing and an inserted position (Fig. 5) wherein the second housing is fully inserted within the first housing so that the terminals of the respective housings are in mating engagement.

Title: Particle separator for the inlet of a gas turbine engine
IPC: F02C7/052
Filed: 1980-04-21
Abstract: A duct 6 is constructed on a nacelle 2 in which the engine 1 is mounted. Air flows into the engine intake plenum 4 via an opening 16 in duct wall 17. A swingable door 9 is mounted at the opening and is movable by actuator 11 from a first position where it partially blocks the opening to a second position, shown, where it blocks the outlet 8 of the duct. In the first position the door causes airflow entering the plenum to bend, hence giving rise to inertial separation of undesired air contaminants. In the second position air entering the duct 6 by the inlet 7 is fed to the plenum, giving a ram air effect. <IMAGE>
Patent GB-2053508-A (GB)
Title: Automatic Control of I.C. Engines
IPC: F02D41/06
Filed: 1980-05-20
Abstract: An intake air flow rate control system for an internal combustion engine has an open loop control system carried out in unstable engine driving condition. In the open loop control, the pulse signal applied to an air flow rate control valve means is determined both by open loop ratio and feedback ratio. The pulse duty of pulse signal for open loop control is varied corresponding to engine coolant temperature. The pulse duty of the pulse signal can be also varied corresponding to engine load condition or an engine starting condition. Thus, upon switching control operation from open loop control to feedback control, varying of pulse duty to be applied to the valve means is smoothly performed. Further, in open loop control, the control system can follow varying of engine load condition smoothly. <IMAGE>

Patent GB-2057221-A (GB)
Title: Device for generating differentially enhanced images
IPC: G06T7/00
Filed: 1980-07-16
Abstract: In a device for generating a succession of time-differentially enhanced images, hitherto, successive images were each stored in a respective one of three video memories. Images from two memories were read out and subtracted to form an enhanced image while the next image was loaded into the other memory. The improvement only requires a single video memory MM20 which forms part of a recursive filter arrangement further including a subtraction circuit V20, an adding circuit A20 and at least one multiplier M20, M21. For each image element, the difference, V20, between the new sampled value from ADC2 and the previous stored value in MM20, is supplied to a display MON. At the same time, (1 -  alpha ) times the stored value (M21) is added (A20) to ( alpha ) times the new input value, (0 </=  alpha  </= 1), and overwritten in the memory MM20. An alternative is disclosed using only one multiplier. The described embodiment relates to the enhancement of fluoroscopy images, e.g. when examining the flow of a contrast medium. <IMAGE>
Patent GB-2077131-A (GB)
Title: Filtration
IPC: B01D33/00
Filed: 1980-07-21
Abstract: In an improved filtering method vibration is induced in a filter cake so as to improve the removal of liquid. This may be achieved by a vibrating roller which bears on the cake on a rotary drum or moving belt filter, or in a filter press with inflatable membranes the membranes may be vibrated hydraulically. In all cases an improvement in cake dryness is achieved. In a modification of the rotary drum or continuous belt embodiments, a ribbed roller 15 may be used to impress or deform the surface of the filter cake prior to vibration by the vibrating roller 11. This deformation improves the engagement of the vibrating roller 11 on the cake. <IMAGE>

Patent GB-2088102-A (GB)
Title: Pulsed current supply apparatus
IPC: G05F1/45
Filed: 1981-11-13
Abstract: Pulsed a.c. current is provided in a secondary circuit of a transformer 3 by periodically preventing passage of complete a.c. cycles by use of a thyristor switching circuit 6 under the control of a timing circuit 8. The thyristor switching circuit 6 is in the secondary circuit rather than in the primary circuit, thus avoiding current surges from switching the primary circuit on and off for each pulse. A current monitor 9 monitors the average current in the secondary circuit rather than in the primary circuit and controls timing circuit 8 so as to prevent the average secondary current from exceeding a predetermined value, saving power, and this is done more efficiently with the more accurate measurement. The apparatus may be used to regenerate activated carbon by arc discharge through the carbon between electrodes 5 in the secondary circuit. <IMAGE>

Title: Arc starting circuit for welding apparatus
IPC: B23K9/067
Filed: 1982-03-17
Abstract: The invention relates to arc initiation in arc welding apparatus and seeks to overcome the problems inherent in the use of high frequency a.c. arc initiating systems. A welding arc is generated by the application of an high d.c. voltage (e.g. 5KV) in an initiation circuit which is isolated from the welding machine 2 by means of a diode 6 in the welding circuit which prevents the initiation current delivered to the weld gap 4 passing to the welding machine. The initiation voltage can be constant d.c. Alternatively high voltage d.c. pulses may be generated by a circuit 12 at a rate which is equal to or a multiple of the a.c. mains supply frequency, circuit 12 being powered by a step-up transformer 8 and a full-wave rectifier 10. In a further embodiment, (Fig. 2 not shown), the output of transformer 8 is fed to the weld gap 4 via a current limiting resistor (16) and a half-wave rectifier (18). The arc-initiation circuit may be turned off automatically by a time switch or by a current-sensitive switch in the welding circuit. <IMAGE>
