Title: Filters for analogue-digital video signal conversion
Inventor: SOCHOR JOSEF
IPC: H04N7/24
Filed: 1990-09-06
Abstract: In a system with a digital transmission path between an A/D converter (4) and a D/A converter (6), respective analogue low pass filters (2) and (7) whose orders differ by 1 are provided adjacent the converters for pre- and post-filtering to prevent aliassing. The standardised frequency response of one of the two low pass filters is multiplied by a factor so that the minima in the echo attenuation response of each of the filters corresponds to the maxima in the echo attenuation response of the other. The effect of the non-ideal filter characteristics (amplitude ripple in the pass band), which accumulates if the signal is repetitively converted between analogue and digital forms, is thus reduced. The digital path (5) may include signal processing or recording. <IMAGE>

Title: Backhoe
Inventor: MIURA KEISUKI
IPC: E02F3/30
Filed: 1991-03-07
Abstract: A backhoe comprises a boom assembly connected to a swivel deck laterally of a driver's section. The boom assembly includes a boom connected to the swivel deck, a horizontal offset mechanism connected to the boom, a bucket arm connected to the offset mechanism, and a bucket connected to a forward end of the bucket arm. A plurality of angle sensors are provided to detect angular relations among the components of the boom assembly, and thus an overall posture of the assembly. Detection signals of the sensors are used to control the boom assembly. When the bucket is approaching the driver's section, the closer the bucket is, the more slowly the boom assembly is moved. The boom assembly is stopped upon entry of the bucket to a danger zone defined adjacent the driver's section (SL1, FL1). Preferably the deceleration rate is in inverse proportion of the distance of the bucket arm from and up to the front danger line and zero thereafter. <IMAGE>

Title: Removing injection moulded articles from between opened moulds
Inventor: THORPE LAWRENCE JOHN
IPC: B29C45/42
Filed: 1991-08-02
Abstract: An arm (14) which is cranked to avoid platen guide rails (24), is pivotally moveable to advance into an open mould between the platens (16, 18) to engage a moulded article (46), and to retract to withdraw it from the mould. The arm (14) advances and retracts under control of a closed hydraulic circuit including rotatable or linear double acting control actuating, and drive piston/cylinders (22, 20). The control piston cylinder (22) e.g. incorporating a double-acting rotatable fin, is displaced by a lever connection (40) operated by the movable platen (16), so that the movement of arm (14) is coordinated with that of the platen (16). The moulded articles (46) are engaged by suction pads (50) on the arm (14), which is linearly axially reciprocated into and out of engagement with arm (14), by a double acting pneumatic cylinder (34). A microprocessor (80, Fig 4) controls the pneumatic cylinder and the suction to the pads (50), in conjunction with proximity sensors which detect the location of the movable platen (16). <IMAGE>

Patent GB-925370-A (GB)
IPC: B23Q7/00
Abstract: 925,370. Machine-tool details. MINING ENGINEERING CO. Ltd. Feb. 28, 1962 [Nov. 30, 1960], No. 41098/60. Class 83 (3). A machine for cutting tubes to length, and then chamfering or trimming the ends, comprises a wood-lined support 11, a parting-off tool 17, and rails 19 to transport the cut tube to axially movable rotatable trimming heads 27, 28, the tube being clamped by V-blocks 21, 24. Support 11 is moved vertically by fluid pressure - operated wedges 12, and the tube is held in the support by a fluidoperated finger 16. V-blocks 21 are actuated by interconnected fluid - pressure cylinders 22, and tapered slides 25 position the tube axially. Each head 27, 28 comprises a shaft 31 driven by an electric motor 32, a spring - urged radially movable slide 33 mounted on a face-plate on the shaft which carries at least one chamfering tool 34, a roller 37 rotatably carried by the slide which follows the profile of the tube bore, and rollers 39 carried by a spring-urged plate 42. In operation, tube 10 is fed in support 11 up to a stop 14, which actuates cylinder 15, to move finger 16 to retain the tube. The latter is parted off by tool 17, which on completion closes a switch 18, thus retracting finger 16 and energizing cylinders 13 to lower support 11. The tube rolls down rails 19 and closes a switch 23 which through a timed delay energizes a solinoid to admit fluid to cylinders 22, and the tube is clamped in the V-blocks between cutter heads 27, 28. A switch 38 is actuated by blocks 21, and the heads are moved towards the ends of the tube, and the latter are chamfered. On completion, the tube engages rollers 39 to move plate 42 to actuate a further switch and the heads are retracted until another switch causes cylinders 22 to unclamp the tube which is then discharged from the machine. In a modification, roller 37 engages the outside of the tube, and the tool chamfers the periphery, or the tube may be chamfered on the inside and outside and/or end faced.

Conveyor 4 has gripping means 14 comprising a pair of jaws 16 which are adapted to grip a cutting element 22. When the gripping element 14 passes around the pulleys 8, 12, the jaws 16 separate to enable the cutting device to be 22 received into or released from the jaws 16. A first pulley 8 is adjacent a receiving station for transferring cutting elements 22 into the jaws 16, and a second pulley 12 is adjacent a discharge station for releasing cutting elements from the jaws 16. <IMAGE>

Title: Dielectric filter having resonators of trapezoidal cross-section
Inventor: AGAHI-KESHEH DARIOUSH
IPC: H01P1/205
Filed: 1993-08-26
Abstract: A dielectric filter 200; 300; 400; having at least two adjacently-positioned resonators 264, 270; 364; 370; 464, 470 extending therethrough. The two adjacently-positioned resonators are of trapezoidal cross-sections to form thereby trapezoidal resonators. The amount of electromagnetic coupling between such adjacent resonators may be then controlled by suitable selection of the configurations of such resonators, as shown in figures 4 - 6, rather than by increasing the spacings between such adjacent resonators. The physical dimensions of the filter can then be minimised giving increased miniaturization in radio communication equipment. <IMAGE>
Patent GB-2273277-A (GB)
Title: Aerofoil with variable geometry expansion surface
Inventor: ASHILL PATRICK RALPH
IPC: B64C23/00
Filed: 1994-01-24
Abstract: A wing, or similar article of aerofoil section, has a variable geometry surface for the active control of shock strength and transonic wave drag. In one embodiment, the wing has a region of distensible skin (4) aft of the line of maximum section, which extends along the span of the wing in those areas that experience drag. Pressure means (10, 20, 30) within the wing outwardly deflect the distensible region and produce a local bulge in the expansion surface. This bulge induces pre-shock compression and reduces the effect of the shock. The bulge is retracted by the natural elasticity of the skin material (which can be a conventional aluminium alloy) upon removal of the applied pressure. In another embodiment, the wing has a ramp portion (14) which is outwardly deflectable for the same purpose. The invention is applicable to supercritical and natural laminar flow wings.

IPC: B44C5/02
Filed: 1994-01-28
Abstract: A mount (7) is prepared from a backing layer (2), a canvas layer (4) and an exposed layer (8) of adhesive. The mount (7) is mass-produced in a factory and is then sent to a customer who laminates a photograph (1) to the mount (7) by applying pressure and heat in order to activate the adhesive of the layer (8). As a result, a canvas-like texture is imparted to the photograph (1). The mount (7) may be mass-produced to a high standard under factory conditions in order to remove the need for the customer to have to simultaneously prepare all of the layers at the time of mounting the photograph (1).   <IMAGE>
