Title: Electromagnetic coupling discs
Inventor: BOOTH DWIGHT E
IPC: F16D27/112
Filed: 1991-05-22
Abstract: One face of a coupling disc 21 (i.e., the armature or rotor) of an electromagnetic coupling such as a clutch or brake is formed with a plurality of radially spaced and circumferentially extending grooves 29. The other face of the disc 21 is formed with a plurality of radially spaced rows of circumferentially extending slots 30 which communicate with the grooves 29 so as to form air gaps completely through the disc. Each groove 29 is circumferentially continuous while each row of slots 30 is defined by circumferentially spaced slots which are separated by short bridges 36. By virtue of forming the grooves 29 in the disc, only a small thickness of material need be removed from the disc in order to form the slots 30. The grooves are formed by a punch (31) (Fig 2) and the slots by punch (36) (Fig 5), a laser (Fig 3). or by machining or grinding (Fig 7). <IMAGE>

Title: Optical disk reproduction
Inventor: LEE CHEON-SUNG
IPC: G11B21/08
Filed: 1993-03-18
Abstract: A method of reproducing an optical disk (10), fig 1 (not shown), can prevent the restraint of an optical pickup (11) in a track due to a scratch on the optical disk. The method includes the steps of checking for an increase of time in accordance with time information of a Q-channel in the demodulated subcode at the current pickup position, and, when the time has not increased, muting a reproduction output and causing the optical pickup (11) to jump as far as a predetermined track. Thus, regardless of the occurrence of an optical pickup restraint phenomenon, reproduction can be continued by track jumping. <IMAGE>

Title: Nest rooms
Inventor: NICHOLSON KIT
IPC: E04H15/04
Filed: 1994-09-22
Abstract: Nest rooms are made by weaving sticks into a framework, to create a structure similar to that of a weaver bird's nest or a wasp nest, but large enough for children and/or adults. The shape of the nest room is defined mainly by the initial framework, whilst the range of sticks used and the way in which they are woven into the framework determines the nature of the screen they provide. Access may be by ladder, steps or woven stick tunnel. Figure 2 shows a completed nest room, hung from a tree. Nest rooms are mainly for outdoor recreational use, either as tree houses, summer houses or hides, located in gardens, parks, woods or playgrounds. Nest rooms may be hung from, built into or otherwise attached to trees, buildings, platforms and/or other structures. They will contain a door-opening and may contain window holes and/or furniture built into the structure. Connecting nest rooms may also be made. <IMAGE>

Title: Treatment of sludge
Inventor: HOBSON JOHN ANDREW
IPC: C02F3/12
Filed: 1993-08-03
Abstract: Sludges, especially sewage sludges, are treated to stabilise them by biological digestion (21) and/or to remove heavy metals (19, 23) by using a sulphur compound cycle in which sulphate is reduced to hydrogen sulphide which is then re-oxidised (36, 40) to sulphate for return to the process. The sulphate reduction is effected during digestion (21) of the sludge and the sulphate from re-oxidation (usually sulphuric acid) is either cycled to the digestion of more sludge, or used to leach heavy metals (14) and subsequently recovered upon their precipitation as sulphides (23). Instead of sulphate, other sulphur species can be used provided they are more oxidised than hydrogen sulphide. <IMAGE>

IPC: F16H25/24
Filed: 1995-06-23
Abstract: A stripper for a threaded spindle has an essentially ring-shaped body, the inner circumference of which is provided with an internal screw thread 12 that works in cooperation with the carrier screw thread of the threaded spindle. The internal screw thread 12 has at least one recess 14 which is open towards the surroundings of the stripper and which interrupts at least one thread. At least one side edge of the recess 14 runs essentially cross-wise to the threads and is configured as a stripping edge 18, and the screw thread area 16 which carries the stripping edge 18 can be pressed into the carrier screw thread by means of a predetermined force. As a result of this stripper configuration, the topmost layer of the residual film of grease and the abrasive dust found on the spindle can be accurately peeled off, even from the low part of the profile, so that layers of grease that are always clean lie at the points of contact between the spindle nut and the threaded spindle. The pressing force may be provided by resilient material 31 or by a surrounding coil spring (20, Fig 2 not shown). <IMAGE>
