Patent GB-2244878-A (GB)
Title: Variable conversion rate analog-to-digital converter
Inventor: ORDWAY FRANK S
IPC: H03M1/52
Filed: 1991-05-01
Abstract: A high resolution and high speed analog to digital converter for use with a transducer in measuring parameters such as weight, which may stay the same or change, integrates for a fixed period the output voltage from the transducer, and subsequently deintegrates a known reference voltage, the deintegration times varying depending upon the magnitude of the transducer output voltage which has been integrated. A comparator compares the deintegration times of successive conversions and shortens the integration time so as to obtain more conversions per time period when the transducer output is changing, but lengthens the integration time to provide a high resolution readout when the comparison of deintegration times does not reveal any change in the transducer output. <IMAGE>

Title: Crawling and talking doll.
Inventor: FERRI JAIME
IPC: A63H11/18
Filed: 1991-08-07
Abstract: A doll incorporates a mechanism which causes the doll to crawl and give out a message and, subsequently, to stop crawling and raise the trunk of its body and head, to turn its head and give out a new message. These movements are repeated until a general switch is activated by means of, for example, a dummy, or by means of a ball switch activated automatically when the doll is picked up and put upright.
Patent GB-2260662-A (GB)
Title: Vehicle deceleration indicator
Inventor: HORTON PHILIP GRAHAM
IPC: B60Q1/44
Filed: 1991-10-18
Abstract: The indicator comprises a pendulum 21 operating a switching system 7, 8, 9, 10, 22 to cause a plurality of lights to be energised in sequence as the degree of deceleration increases. The pendulum may carry a magnet 22 to operate reed switches 7, 8, 9, 10. Alternatively, the pendulum may operate direct mechanical contacts, or adjust a resistor connected to an electronic circuit controlling the lights, or light sensitive switches may be used. The indicator system is enabled by a relay (18), (Fig 3), energised by the normal brake switch (6) or by a test switch (25). The reed switches 7 to 10 energise respective self-latching relays (11) to (14) so that pairs of lights (2) to (5) are energised in sequence with increasing deceleration, whereby the number of lights energised indicates the degree of deceleration. Opening of the brake switch (6) allows the relays (11) to (14) to unlatch. <IMAGE>
Patent GB-913549-A (GB)
IPC: F04B1/12
Abstract: 913,549. Swash plate pumps. ROLLSROYCE Ltd. July 22, 1959 [July 23, 1958], No. 23791/58. Class 102(1). A rotating cylinder swash-plate pump comprises plungers co-operating with a swash-plate through slippers wherein liquid is delivered from an auxiliary space during the delivery stroke of the plunger to form a liquid film on the bearing surfaces of the slipper. In the embodiment shown in Fig. 1 the plungers 12 are stepped and reciprocate in stepped bores 11, the steps forming the auxiliary chamber which is in communication with the slipper pad 14 through passages 25, bore 24 and passage 26. The auxiliary chamber is separated from the pumping chamber by a plug 23 in the piston bore. A groove 20 extending over approximately half of the valve plate 15 is in communication with the outlet port 18 and feeds high pressure liquid to the auxiliary chamber through passage 19 during the return stroke of the plunger, this pressure assisting the return stroke. During the delivery stroke the passage 19 is closed by the valve plate and liquid in the auxiliary chamber is fed to the slipper pad provided with the various passages 27, 28, 30 to form the required film. In a modification, Fig. 6, the auxiliary chamber 40 is formed in the bore of the piston 12 by a fixed member 41 attached to the bore 11 by a spider 41b. The chamber 40 communicates with the passage 19, controlled by the valve plate as above, through passage 44 and groove 43.

Title: Weather-proof garment convertible into a range of other outdoor articles
Inventor: COURTNEY WILLIAM ALEXANDER
IPC: A41D15/04
Filed: 1994-03-31
Abstract: This garment is convertable into other articles of use to hill walkers, mountaineers and others. It comprises a sheet of waterproof material which can be folded and fastened to create a bag large enough to enclose the whole of the wearer. The sheet has both touch-and-close fasteners and snap fasteners at or towards its edges and includes a removable headband 3. Fig. 5, near its perimeter. The garment can function as a survival or bivouac sac or it can be worn as a cape or poncho and adjusted to provide a hood (Fig. 7). It can be converted, amongst other things, to act as a wind and rain shelter, tent, sleeping bag, basha, hammock, stretcher, one and two man systems for carrying a casualty. The garment may be used as a water still, for collecting dew or it may be combined with buoyant objects to form a life raft. A version of the shelter, in suitable camouflage colours, may be used as a wild life observers hide. It has a number of uses of interest to mountaineers and others operating in snow covered landscapes. The garment may be formed into a shelter (Fig. 8) or modules may be added to extend the volume of the shelter (Figs. 18 to 21) and to combat a range of environmental hazards including heat loss and flying insects. A heat retention and cushioning module (Fig. 24) can be inserted inside the garment. This cushioning module can also be adapted to form a splint to give support to a fractured limb. The equipment includes a rucsac docking module (Figs. 16 and 17) which allows a rucsac to be docked to the garment, providing access to the contents of the rucsac from inside the garment when the garment is used as a shelter or bivouac sac. A lightweight sleeping mat module may be attached to the garment. It may also be used in conjunction with the garment to function as a vapour barrier sleeping bag and as a buoyancy aid. The sleeping bag (Fig. 25) may be formed of bubble packing material laced at its edges through reuseable eyelets (Fig. 26). The garment may be formed into a stretcher (Fig. 10). A preferred design of touch-and-close fasteners is described (Fig. 13). <IMAGE>

Title: Image forming apparatus with toner remover between images
Inventor: GUTH JOSEPH EDWARD
IPC: G03G15/00
Filed: 1995-01-23
Abstract: Image forming apparatus forms first and second toner images in the same portion of an image member. To prevent scavenging of toner in the first image into a second toning station, lightly held toner in the first image is removed from the image member prior to the second toning station. As shown, the first toner image is produced by image-wise exposure by LED of charged belt 1 followed by development at station 15 to produce a coloured image which is exposed to erase lamp 19 to reduce scavenging before recharging at 20 and second exposure at 17. To reduce migration of first toner image and contamination of second toner image, loose toner particles from the first image are removed by roller 42 with an electrical bias 44 before developing second image at 25 of different colour to the first image. Alternatively a vacuum may be used to remove excess first toner. <IMAGE>

Title: Inserting header code words
Inventor: HAMANO TAKASHI
IPC: H04N19/107
Filed: 1995-03-14
Abstract: For image data such as video image data composed of three hierarchical layers formed of slices, each of which having a plurality of macroblocks and one picture having a plurality of the slices e.g. MPEG-1 and MPEG-2, a synchronous header word is adaptively inserted to each of the slices according to a characteristic property of the image data, e.g. motion. It is possible to effectively perform the localization of errors. A synchronous word multiplexing system for coded image data inputs and codes image data, converts the coded data to a variable-length coded data, divides the image coded data into a plurality of data signals, and multiplexes a synchronous word per a predetermined divided unit. Further, a timing signal for multiplexing synchronous words to the image coded data is generated based on a characteristic data, and the timing of multiplexing synchronous words is controlled based on characteristics of the image data. <IMAGE>
