Title: An actuator mechanism for lifting and lowering the supporting surface of piece of furniture, such as a bed or chair, having a locking mechanism for maintaining the supporting surface in a vertical position obtained by means of the actuator mechanism
IPC: A61G7/018
Filed: 1980-07-31
Abstract: An actuator mechanism (14) for lifting and lowering the supporting surface (3) of a piece of furniture, such as a hospital bed or a dentist's chair, comprises an energy accumulating spring means (15), preferably having a gently sloping spring characteristic, the spring force of which is transmitted to the supporting surface (3) via a linkage consisting of a push rod (17) and a first link (19). A second link (24) connects the hinge point (18) between the push rod (17) and the first link (19) with a second hinge point (23), which is connected to a fixed point (22) of the furniture frame via a pivotal adjustment arm (21). By pivoting the adjustment arm (21) to various angular positions it is possible to vary the moment of the spring force about the second hinge point (23) in such away that, given the value of the spring force, the lifting force acting on the supporting surface varies. The lifting force can thus be adapted to precisely balance the variable total weight of the movable parts of the piece of furniture whereby lifting and lowering of the supporting surface can be effected either manually or by a slight pivoting of the adjustment arm. <IMAGE>

Title: Pneumo-mechanical braking cylinder for pneumatic braking systems in vehicles
IPC: B60T17/08
Filed: 1980-10-08
Abstract: A pneumo-mechanical braking cylinder for pneumatic braking systems in vehicles of the type having two coaxial sections, that is to say a pneumatic section A for duty braking and a mechanical section B for parking or aid braking of a vehicle, is fitted with a protective device D to achieve operation of only the mechanical section in the case of simultaneous duty and parking braking of the vehicle, in order to avoid overstraining the operating members of the braking shoes or blocks. The protective device D comprises a unidirectional valve 10 which allows the passage of compressed air from the chamber 4 of the pneumatic section to the chamber 7 of the mechanical section when the pressure in the latter chamber is lower than the pressure in the pneumatic section chamber 4. Thus if chamber 4 is supplied with compressed air at the same time chamber 7 is connected to exhaust, pressure cannot build up in chamber 4 thereby braking is prevented and only mechanical parking braking is possible. <IMAGE>

Title: A process for solidifying radioactive liquid waste
IPC: G21F9/14
Filed: 1981-04-06
Abstract: In a process for solidifying radioactive liquid waste, its pH is adjusted, solids precipitated and then it is concentrated to about 50% solids content using a thin film evaporator, the concentrate then being dried to powder in a heated mixer. The mixer has a a heated wall and working means, e.g. a rotor and helical screw, to shear the dried concentrate from the internal walls, subdivide it into a dry particulate powder, and advance the powder to the mixer outlet. The dried particles are then encapsulated in a suitable matrix. Vapour from the mixer and evaporator is condensed and recycled after any particles have been removed from it. The mixer may both dry the concentrate and mix the dry particles with the encapsulating matrix, and possibly, part of the mixer may be used for pH adjustment and precipitation.

Title: Radar apparatus
IPC: G01S13/30
Filed: 1981-07-23
Abstract: A radar transmitter transmits a group of pulses as shown at I, the group consisting of first short pulse of frequency f1 transmitted during time interval t1 to t2. A second, longer pulse of frequency f2 is transmitted during time interval t2 to t3 and a third, short pulse of frequency f1 is transmitted during time interval t3 to t4. The return from a close range small target is shown at II and the return from a large source of clutter or another large target at a slightly greater range is shown at III. The return from the larger target or source of clutter is so strong as to saturate the receiver during the time interval t7 to t12 and thus the return from the second short pulse during period t9 to t10 is obscured as shown at IV. However, since a short pulse is also transmitted before the long pulse its return, at time interval t5 to t6, is not obscured. In other situations where a large source of clutter or a large target is at a slightly closer range than the small target of interest the return during interval t5 to t6 will be obscured but the return of the second pulse during time interval t9 to t10 will not be obscured. In this way it is ensured that at least one of the two short pulses is detected. <IMAGE>

Title: Automatic speed control of combine harvesters
Inventor: DANBY RICHARD CHRISTOPHER GOWE
IPC: A01D41/127
Filed: 1982-09-09
Abstract: A combine harvester is equipped with grain loss sensors and their response is used to govern the speed of the combine to keep the loss to acceptable limits. To overcome the inherent delay factor, the harvested crop volume, which has a short term correlation with grain loss, is also monitored, and the combine speed is increased or decreased according to whether this volume is below or above a norm. A further control can be applied by monitoring the power applied to the threshing mechanism and reducing combine speed when this attains a maximum.

Title: Apparatus for determining the time-behaviour of ultra-short optical pulses
Inventor: GEITTNER PETER
IPC: G01J11/00
Filed: 1983-07-06
Abstract: Apparatus is provided for determining the time-behaviour of ultra-short optical pulses which avoids the disadvantages of fast detectors, streak cameras, or second harmonic generation apparatus. The pulse shape as a function of time and the pulse duration are determined by means of a linear auto-correlation function obtained by means of an optical interference process. A pulsed beam LS is divided into two subbeams a, b via a beam splitter ST. These subbeams are reflected by reflectors S1, S2 and are recombined by the beam splitter. The interference pattern formed in the recombined beam is measured D as a function of the shift (WZ2) of one of the reflectors S2, which is movable along the subbeam b axis. The intensity distribution in the interference pattern is analysed to produce information about the pulse shape and duration. <IMAGE>

Title: Imaging system
Inventor: PIKE EDWARD ROY
IPC: G01S17/89
Filed: 1984-05-10
Abstract: A resolution enhanced imaging system provides improved target resolution by combining image information with system impulse response and a weight function expressing prior knowledge, ie probable target extent. The system may comprise a radar transceiver 10 and a heterodyne signal processor 14 providing in phase and quadrature image data. The data are processed to provide a conventional diffraction limited image. Pixels 17 above a preset threshold 21 are accorded the weight factor unity, and those below zero. The weight factors collectively form a weight function 22 which is combined with the system impulse response 23, for use in a singular function 24 decomposition 25 of the original complex image data 15. Object data is reconstructed 28 from this decomposition with noise-corrupted terms being omitted 26. This provides better resolution than the original image data. The invention is applicable to imaging targets in a negligible background, such as in air search radars. <IMAGE>

Title: Magnetic head with azimuth having a tip portion oriented in a given direction and method for manufacturing the same
Inventor: TAKAYASU TOYOAKI
IPC: G11B5/187
Filed: 1984-09-28
Abstract: In a magnetic head with azimuth gap, gap width-defining recesses (14, 14') provided on both sides of the gap (18) are arranged to extend in a longitudinal direction of a tape-contact surface (17S) of the head (17). As a result, a magnetic tip portion (19) defined between the recesses (14, 14'), which are filled with a non- magnetic material (15), extends in the longitudinal direction which corresponds to a gap locus defining a track pattern on a magnetic recording tape. To this end the gap width defining recesses (14, 14') are formed on upper surfaces of first and second magnetic blocks (11, 11') such that side walls defining each recess (14, 14') are inclined from a plane (L) normal to the upper surface. The inclination is preferably equal to a desired azimuth ( theta 2) at which angle an intermediate product formed by an assembly of the first and second magnetic blocks (11, 11') is cut into a plurality of head assemblies (17). Each of the gap width- defining recesses (14, 14') may be formed such that corners thereof are rounded. <IMAGE>
