Title: Marking supports for laboratory samples
Inventor: HUGHES THOMAS FERGUS
IPC: B01L99/00
Filed: 1990-06-28
Abstract: A device for marking supports for laboratory samples, which in one example consists of plastic cassettes, includes a clamp 1 for securely holding a cassette 2 to enable it to be marked by a hot-foil printing technique. The technique uses a heated stylus 3 movable by a plotter mechanism 4 over a foil strip 6. A vertical hopper 11, located above the clamp 1, retains a stack of unmarked cassettes 21 and an ejector mechanism displaces the cassette 2, when marked, from the clamp 1 and positions in the clamp an unmarked cassette 12 from the bottom of the stack in the hopper 11. In another example (see Figure 7) the device is intended to mark glass slides, in which case the stylus has a rotatable diamond tip for engraving. <IMAGE>

The appliance may be a dishwasher or a cooker oven. <IMAGE>
Patent GB-2240889-A (GB)
Title: Clamping circuit
Inventor: MCGANN MELVYN
IPC: H03K5/003
Filed: 1990-12-06
Abstract: A clamping circuit comprises a pair of operational amplifiers A1, A2 where the input signal at A has its d.c. level removed at capacitor C1 and a reference signal is applied to the non-inventing input of amplifier A2. The voltage at C cannot rise above zero since the output of the operational amplifier would fall by a corresponding amount and the peaks of waveform are therefore clamped to zero. With amplifiers A3, A4 the signal at D cannot fall below the reference signal at the non-inventing input of A4 and is therefore clamped to zero or some pre-set fixed level at the peaks of reference signal, which is the voltage at point C. Diode D3 conducts when voltage at C attempts to go positive to pull voltage at B to zero as the output of A2 is negative. When C goes negative, diode D4 conducts to keep A2 in active mode. <IMAGE>

Title: Testing programmable logic devices
Inventor: HOR-RICHARDSON PETER
IPC: G01R31/3185
Filed: 1991-02-14
Abstract: To test a programmable logic device (15), a decoder device (10) is attached (11) to the PLD; each PLD terminal is sequentially tested as in Fig 2 to determine whether it is an input or an output; and all possible input combination are sequentially applied (13) to each input. For each combination the condition of each output is determined (13), and the conditions of the output are processed (14) to determine the function of the output. In Figure 2 the resistors (16) are chosen so that input pins of PLD (15) change state when an input is switched from low to high whereas output pins do not change state when the same switched input is applied thereto. <IMAGE>

Title: Strengthening the roots of gear teeth
Inventor: NAKAMURA SHIGETOSHI
IPC: B23P9/02
Filed: 1991-02-15
Abstract: For strengthening the teeth (14a) of a gear wheel (14), the bottom lands (14b) of the teeth are pushed by a stamping tool eg. in the form of a stamping die (18) against a backup gear (16) to cause residual compressive stress at locations extending from the bottom lands (14b) to roots (14c) of the teeth. The stamping tool (18) has stamping projections (18a) which are angled at the tips thereof so as to have tapering ends which are brought into contact with the bottom lands (14b). The stamping tool is axially movable relative to the workpiece such that the tapering ends are brought into contact with the bottom lands at different axial locations of the gear wheel. In a modification (Figs. 3-5) the stamping projections of the rotary die have top lands which are angled axially of the die so as to have tapering ends. The stamping tool and the backup gear may be in the form of racks (Fig. 6). <IMAGE>

Title: Method of forming bamboo fibres and a resin moulding reinforced with bamboo fibre
Inventor: AKIYAMA NORIHITO
IPC: D01B1/50
Filed: 1991-12-17
Abstract: A method of forming bamboo fibers comprises: a first step in which lengths of bamboo are crushed along the grain; and a second step in which the bamboo processed in the first step is fed by a conveying roller into a fibrillating device which includes a drum having many teeth and in which the bamboo is fibrillated. The bamboo may be further broken into fine fibers by a turbo-mill. Thus, the bamboo can be entirely fibrillated. A mixture of such bamboo fibers and a modified melamine resin is cured to form a useful hardened resin molding. The moulding may contain a filler. After one end portion of bamboo is fibrillated the rotation of conveying roller is reversed to draw the bamboo out and the bamboo is turned end for end before it is refed for fibrillating.

Title: An assembly for connecting an operating member of a latch to a handle
Inventor: HOPPER STEPHEN
IPC: E05B13/00
Filed: 1992-02-26
Abstract: The assembly includes two elongate members 13 which are interconnected by a rotary element 18 having lefthand and righthand threads. The members 13 can be positioned so as to interconnect a latch operating member 10 and two door handles 25 so that operation of the handles operates the latch 11. The members 13 are to be moved apart to disengage the operating member 10 so the operation of the handles will not operate the latch. To move the members 13 apart, the element 18 is turned by a key 22 which passes through a hole 27 formed in one of the handles. <IMAGE>

Title: Variable data rate channels for digital networks
Inventor: BURREN JOHN WALTER
IPC: H04J3/16
Filed: 1992-05-27
Abstract: Data packets are stored-in queues 174 to 178 corresponding to groups of ISDN channels which are combined to form high bit rate channels, known as slots and U-channels, respectively. Data is assembled from the queues into ISDN frames held by a frame buffer 172 using an appropriate number of slots in the frame for each U-channel, and the frames are transmitted via a terminal 11 to the network. On reception in frame store 182 slots in frames are passed to packet assembly buffers 154 to 188, one for each U-channel, before being passed to users as data packets. When a new slot is to be added to a U-channel without interrupting data in the existing slots, synchronisation signals are sent in the new slot and a system of flags is used to establish when data is to be sent in the new channel. When the bit-rate of a U-channel is to be reduced by removing a slot, a distinctive closing sequence is sent in that channel which on reception is an indication that no further data will be sent in that slot. <IMAGE>

Filed: 1993-05-10
Abstract: An internal combustion engine in which each cylinder is connected to sources both of air and of fuel held as a gas under pressure and in which the compression stroke, during which a full charge of air is drawn and compressed, is substantially completed before the fuel charge is then admitted and the mixture ignited to start the subsequent power stroke. The fuel may be admitted through a unit doubling as admission valve and igniter, and conventional diesel or gasoline-fuelled engines may be converted by designing that unit to fit into the conventional injector or spark plug holes. The compressed gaseous fuel may be methane, or other natural gas. The invention includes both stationary and mobile engines, especially automobile engines, and methods of operating them. <IMAGE>

Filed: 1994-12-14
Abstract: A porous polytetrafluoroethylene (PTFE) structure suitable for use as an oil transfer component for coating or wiping a roll in a fuser system of a copying machine has a fibrillated surface. The PTFE structure is formed from particles of granular-type polytetrafluoroethylene fused together to form a porous integral network of interconnected particles, and is produced by casting a PTFE suspension onto e.g. a mesh and drying, so that the PTFE engulfs at least some of the wires of the mesh. Removal of the PTFE sheet from the mesh results in a fibrillated irregular surface 72, 74. <IMAGE>

Title: Roller shredder
Inventor: ASHTON PETER JOHN
IPC: B02C18/14
Filed: 1995-04-28
Abstract: A roller shredding which comprises a first roller (2), a contra-rotating second roller (3), each having tooth-like shredding members (4a to 4f and 4a' to 4f') mounted thereon and a clutch provided to permit relative circumferential adjustment between the two rollers. Circumferential adjustment between the rollers is made when it is required to alter the co-operative action between a pair of co-operating shredding teeth, when worn along co-operative facing edges, whereby the unworn opposite edges of the teeth can carry out an alternative slicing action with different shredding teeth. This allows both slicing edges of the shredding teeth to be fully utilised, before the machine has to be stripped down for replacement of worn shredder teeth.
