IPC: B68G7/08
Filed: 1985-06-27
Abstract: A structure for a decoration button for use in a vehicle seat is disclosed in which button material, (1), together with a reinforcing material, (2) is pressurized against the back side of a trim cover assembly (b) including a covering material, (b1) a wadding of foam material (b2) and a wadding cover, (b3) and the three elements of the assembly and the reinforcing material existing around the button material are welded integrally and collapsed in an annular manner to form the decorative button on the covering material side, so that the button material is covered with the three elements to prevent a strange feeling on sitting. The welding may be carried out by a high-frequency welding device.

Title: Separating or cleaning particulate material
Inventor: CHONG BOON LEK
IPC: B03B5/56
Filed: 1985-07-18
Abstract: Particulate material is conveyed through a rotating conduit 1 by helical vanes 8 against an opposing flow of fluid. A pipe 13 extends into a first end 2 of the conduit 1 to deliver fluid and a chute 14 extends into the second end 3 to deliver particulate material. The conduit is inclined to the horizontal to provide a downward gradient for fluid flow and is constricted at the first end 2 to prevent backflow of fluid. Rakes 15 are fixed to the internal walls of the conduit for providing agitation. The conduit is housed in circumferential bearings and driven through a circumferential gear. The apparatus may be used with a fluid which is a liquid or liquid solvent in a cleaning process where cleaned particles emerge at the first end and soiled liquid at the second end. Used in a separating process, coarse particles emerge at the first end and fine particles at the second end. <IMAGE>

Patent GB-2171776-A (GB)
Title: Pistons
Inventor: FELICI ALBERTO
IPC: F02F3/00
Filed: 1986-03-03
Abstract: A piston has skirt portions (13) which are provided with parallel rows (14) of cavities (15) defined by walls 16, 17 and whose maximum depth below the surface of the skirt portion is 0.010 mm. Parts (20,23) of the skirt portion are left between the cavities for providing a reduced area, in comparison with the full skirt portion, for the transmission to an associated cylinder or liner of lateral loads; this reduced area reducing the frictional losses. The cavities (15) hold lubricating oil and provide a cushion of oil which supplies oil to the reduced bearing areas and which tends to resist lateral movement of the piston at top and bottom dead centre, so reducing the eliminating "piston slap". <IMAGE>

Patent GB-2189950-A (GB)
Title: Modulation circuits
Inventor: SALMON JOHN CHARLES
IPC: H02M1/08
Filed: 1986-04-04
Abstract: A pulse width modulation circuit comprises a stepping counter 20, an EPROM 21, a synchronising circuit 22 and an up/down counter 23. Values within the EPROM 21 are addressed sequentially by the counter 20 to output signals to logic circuitry 24 to 29 which in turn applies count-up pulses to the count- up input 33 and count-down pulses to the count-down input 34 to cause counting of the count output in one direction. A JK flip-flop 30 coupled to the count output 35 alters the logic circuit operation when the count output reaches either a preset maximum or (a) minimum value, so that continued application of pulses to the counter 23 causes counting of the count output in the opposite direction. In this manner a well-defined square-wave output signal is obtained at the output of the flip-flop 30 having a mark-space ratio which is variable by varying the stepping frequency of the counter 20. <IMAGE>
Patent GB-2521091-A (GB)
Title: Phase conjugation system
Inventor: SCOTT ANDREW MAXWELL
IPC: H01S3/10
Filed: 1986-05-08
Abstract: A phase conjugation system (10) comprises a master laser (12) arranged to produce two pulses (14a, 14b) with a relative delay. Reflections of the two pulses (14a, 14b) from a remote target return to the system.The first reflected pulse is employed in the generation of two pump beams to produce to pump a Brillouin scattering cell (40). The second reflected pulse arrives at the cell (40) in synchronism with the pump beams to produce retroreflection by four wave mixing. A further Brillouin cell (34) may be used to frequency shift the pump beams giving Brillouin enhanced four wave mixing. The threshold for retroreflection to occur in four wave mixing is several orders of magnitude below that required using a prior art stimulated Brillouin scattering approach.

Abstract: A manually operable electrical toggle switch (60) is connected in a low current signalling link (40) via a non-intelligent slave unit (20) in a time slot assignment multiplex system for automotive vehicles to an intelligent master unit (10) which in response to a binary input from the switch (60) provides an output signal on such a signalling link (40) to control high current to a load (70) connected to a slave unit (20). The binary input from the switch (60) is provided by one of two resistances (R2 or R3) which are distinguishable in the master unit (10) from each other and from both a short circuit and an open circuit in the signal line (42) of the link (40). The condition of the switch (60) and its wiring (27) to the slave unit (20) may thus be diagnosed without manual operation of the switch as a programmable function of the master unit (10), via the master unit by a tester (80), or via the slave unit (20) by a tester (90) prior to assembly in the complete system. <IMAGE>

Title: Frequency synthesisers
Inventor: CZAKO LASZLO
IPC: H03L7/107
Filed: 1989-06-15
Abstract: In a frequency synthesiser, the frequency of a controlled signal source 1 is varied in a predetermined manner and the phase difference between its output and a reference signal is determined at 5 and the phase of the controlled signal and/or the reference signal is shifted such that the phase difference approaches a steady state value. The oscillator 1 is pretuned by an arrangement 10 including a sequential control circuit 11 incorporating a c.p.v. and then its output is varied in a predetermined manner. The circuit 11 adjusts the division ratio of 2 and the band-width of filler 6 during tuning and also synchronises the operation of a timing circuit 7. The relative phase difference of the controlled and reference signals is measured at 7 in a sampling manner and used to control the phase shift of 8 in between sampling. Increase in tuning is achieved in a stable manner. In a modification, the phase shifter 8 is dispensed with and the division ratio of 2 is further controlled by timing circuit 7. The frequency synthesisers may be used in telecommunication, measurement, broadcast reception etc. <IMAGE>

Abstract: A process for the production of an upholstery part (16, 32, 42) is described, in which first of all a covering (16) is introduced in a closely fitting way into a casting mould (10). Subsequently, the casting mould (10) is initially closed with a first lid (24), after which a flexible foam reaction mixture (28) is introduced into the first cavity (12) of the casting mould (10) bounded by the first lid (24). After the reaction process, the flexible foam reaction mixture (28) fills the first cavity (12) and forms a flexible foam body (32). Subsequently, the first lid (24) is removed from the casting mould (10) and replaced by a second lid (30), the flexible foam body (32) remaining in the casting mould (10). A second cavity (36) is thereby formed between the flexible foam body (32) in the casting mould (10) and the second lid (30). Subsequently, a rigid foam reaction mixture (40) is introduced into the second cavity (36), which mixture fills the second cavity (36) after the reaction process as a rigid foam body (42).

Title: Apparatus for monitoring fetal heart rate
Inventor: KIRK DERRICK LAURENCE
IPC: A61B8/02
Filed: 1989-07-04
Abstract: A problem which occurs in monitoring the fetal heart using Doppler shift in ultrasound is to distinguish between maternal blood flow and blood flow in the fetal heart. The present invention is directed to overcoming this problem in two ways: firstly, by using a multi-range receiver (12), in which output signals are multiplied together, to receive and process the incoming Doppler signals so that varying positions of the fetus can be accommodated together with mothers of widely differing sizes; and secondly, by using a waveform comparison (14) to compare the waveform received with a typical fetal heart waveform. The waveform comparison is carried out by means of two registers containing samples of the waveforms and a multi-bit exclusive NOR gate comparing the samples on a bit by bit basis. The comparison includes summing the bits in the exclusive NOR gate without taking account of their significance.
