Title: Control means for a setting drive
Inventor: HANK DIETRICH
IPC: G05B11/18
Filed: 1986-05-07
Abstract: Control means for the regulating of, for example, web unrolling in an automatic magazine paster of a rotary printing machine, comprises a movement direction discriminator (2) and a multi-step regulator (1), the outputs of the regulator (1) and of the discriminator (2) being connected with the inputs of a logic network (3). A control signal for crawling motion of a setting drive is derivable at a first or a second output (-y1, +y1) of the logic network (3) when the regulating magnitude is disposed outside a tolerance field +/-a2 and exhibits a tendency to reduce and a control signal for rapid motion of the drive is derivable at a third or a fourth output (-y2, +y2) of the network when the regulating magnitude is disposed outside the tolerance field +/-a2 and exhibits a tendency to increase. The activation of the first or third output (-y1, -y2) corresponds to a first setting direction and the activation of the second or fourth output (+y1, +y2) to a second setting direction. When the regulating magnitude is outside a fine tolerance field +/-a, but within the coarse tolerance field +/-a2 the crawling motion of the setting drive is derivable at the first or second output (-y1, +y1). <IMAGE>

Title: Fluid expulsion system
Inventor: DUFFY KEVIN JAMES
IPC: B67D1/08
Filed: 1987-05-01
Abstract: A fluid expulsion system for use in expelling fluid, for example, air from a container 3 comprises a stopper 1 for sealing the container and through which a passage 4 is provided having a one-way valve 5.

Title: Pull-cord arrangement for babies
Inventor: TROSCIANKO DR TONASZ STANISLAV
IPC: A63H33/00
Filed: 1987-08-05
Abstract: The claimed invention comprises a pull-cord arrangement which allows babies having different degrees of mobility and manual dexterity to operate a device attached to the side of the cot, such that when the baby exerts a force on the pull-cord, the device is switched on. A system based on two pull-cords, which attach in three different ways, is described. A large strap hangs across the cot, and a shorter strap can be hung either from the longer strap, or directly from the device. The device can be a tape-player designed to have one side facing the baby and containing only the loudspeaker and switch attachment, while the other side, inaccessible to the baby, contains all other controls and the tape-loading mechanism. This system allows the baby to play pre-recorded sounds to itself on demand. <IMAGE>

Patent GB-2206212-A (GB)
Title: Determining position and/or replacement
Inventor: RUSSELL ALEXANDER
IPC: F15B15/28
Filed: 1988-06-20
Abstract: Absolute determination of position/displacement e.g. of a piston 13 in a hydraulic ram is by means of a loading armature 19 carried by the ram piston and shiftable along a stationary elongate stator 17 having a regularly multi-tapped winding forming a series of windings each of axial length equal to half the axial length of the armature. "Coarse" determination of the armature position is effected by scanning the series of windings and for each winding measuring the impedance. Detection of low impedance shows the presence of the armature. Thereafter, a group of the windings in the vicinity of the armature is examined by means of a bridge circuit and analogue values of impedance used to determine accurately the "fine" position of the armature. A feature of the apparatus is automatic step-switching between adjacent groups of windings so that analogue values are maintained within limits corresponding to linear variations. The armature 19 is a solid metal insert e.g. of aluminium and the starter is anchored by a pressure-tight gland 18. <IMAGE>

Title: Pixel intensity modulation in a waveform display
Inventor: ALAPPAT KURIAPPAN PAUL
IPC: G01R13/34
Filed: 1989-01-05
Abstract: A digital oscilloscope produces a waveform display in response to waveform data sequences acquired by sucessively digitizing an input signal. The waveform display represents the magnitude of the input signal as a function of time by selectively illuminating pixels of an array of pixels on the screen, wherein each pixel represents a different combination of input signal magnitude and time. The intensity of each pixel of the array is an increasing function of the number of acquired waveform data sequence elements having associated therewith a magnitude and relative sampling time most nearly similar to a magnitude and relative sampling time represented by the pixel. The intensity of each pixel is also a decreasing function of time. Repetative waveforms therefore show an increase in brightness whereas noise (occupying different time/magnitude coordinates from field to field) rapidly fades. <IMAGE>

Title: Refillable pen-style perfume atomiser
Inventor: WINTERFLOOD SIMON BERESFORD
IPC: B05B11/00
Filed: 1989-03-21
Abstract: A perfume atomiser, with cap and body in the style of a pen, can be refilled from larger donor bottles of perfume. In the case of ordinary donor bottles - that is those that are neither atomiser or aerosol, sections 10 and 11 are separated and 10 is filled by pouring. Alternatively with donor atomisers and aerosols, refilling is conducted by separating 10 and 12, removing the spray nozzle of the donor atomiser or aerosol, inserting the stub of the donor's pump mechanism into the cone shaped aperture at the base of 10 and using a pump action to inject the perfume. Air compressed in the body as it fills is released through a one-way valve 13 and outlet tube 15. <IMAGE>

Title: Removing dust from used foundry sand recovery apparatus
Inventor: SATMER FRANZ
IPC: B22C5/10
Filed: 1990-11-28
Abstract: A rotated drum 1, for used foundry sand recovery, contains an independently rotated rotor 3. In the upper drum region a dust removal device includes a suction conduit 40, connected with a discharge line 46, and a discharge channel 48 at one axial end of the drum. The conduit 40 is curved in transverse section and has perforations 42 in the inner curved wall 41 so as to hinder the intake of sand from the stripper 5 which removes sand from the drum wall as the drum rotates so that the sand falls onto the rotor blades. Between the dust conduit 40 and the rotor 3, are baffles 51 which form labyrinth-like passages 57 for the dust as it travels to the suction openings 42 in the dust conduit 40, further reducing unwanted sand intake. The openings 42 may increase in size with increasing distance from the discharge 48 so as to compensate for the greater travel path. <IMAGE>

Title: Termination of hydrophone towed array strain member
Inventor: BAYLISS MARTIN WILLIAM
IPC: F16G11/05
Filed: 1991-05-09
Abstract: A termination arrangement 30 for a hydrophone towed array streamer, incorporating a flexible hose 11 in which strain member ropes 12 are contained to form a circular array at the hose end, includes a stack of annular anchor blocks 34, 35 containing through-apertures 38, 44 into which the ropes are passed. The first block 34, nearest the hose, has both tapered apertures 38T, in which some ropes are spread and anchored by pin and/or resin, and untapered apertures 38U,through which the remaining ropes pass unsecured to aligned tapered apertures 44T in the succeeding block where they are likewise spread and anchored. Because some of the apertures in block 34 are not tapered a greater density of through-apertures is possible in the block 34 and thus a greater number of ropes can be incorporated in the hose and individually terminated in the anchor blocks. Block shoulders 36, 37 may not be perpendicular to the blocks' axis (Fig. 4), the tapered bores need not extend right through the blocks (Fig. 5), all the blocks may be located on a common core (Fig. 7), and the through holes may be reverse-tapered to aid rope threading. <IMAGE>
