Title: Particulate material
Inventor: AKINMADE ADEMOLA OLASENI
IPC: A61K6/884
Filed: 1997-03-03
Abstract: A particulate material is made by grinding the product of reacting submicron acid-degradable fluoridated aluminosilicate glass to completion with poly(acrylic acid). This material is used in a two-paste cement pack for a dental cement which, when mixed, cures by light-activation, a glass ionomer reaction and a chemical curing. Both pastes contain cross-linkable methacrylate monomers and the above pre-reacted particulate material, which is fluorine-containing glass ionomer cement totally depleted of unreacted glass. The first paste also contains poly(acrylic acid) or poly(vinyl phosphonic) acid or both. The second paste, which is a command-cure cement in its own right, contains a zinc glass and poly(acrylic acid) but the reaction between these is held in suspended animation until the paste is exposed to air and light.

IPC: E21B10/54
Filed: 1997-09-24
Abstract: A combination metal milling and earth drilling tool (10), for use in performing a single trip kickoff from a casing in a well bore. The combination milling and drilling tool (10) has a first, relatively more durable cutting structure (20a, 22), such as tungsten carbide, and a second, relatively harder cutting structure (20b, 24), such as polycrystalline diamond. The more durable first cutting structure (20a, 22) is better suited for milling metal casing, while the harder second cutting structure (20b, 24) is better suited for drilling through a subterranean formation, especially a rock formation. The first cutting structure (20a, 22) is positioned so that the first cutting structure (20a, 22) will mill through the metal casing while shielding the second cutting structure (20b, 24) from contact with the casing. The first cutting structure (20a, 22) can wear away while milling through the casing. The second cutting structure (20b, 24) can then be used to drill through the rock formation.
Patent GB-2340679-A (GB)
Title: Frequency synthesizer
Inventor: BRISTOW ROBERT OWEN
IPC: H03L7/197
Filed: 1998-08-17
Abstract: A frequency synthesizer comprises first and second phase locked loop (PLL) circuits 10 and 11 for generating two frequencies simultaneously, for example the receiver and transmitter frequencies 12 and 13 of a mobile phone. In order to generate frequencies which are non-integer divisors of a reference frequency 7, the dividing value sent to divider circuits 2a and 2b in each PLL is perturbed in such a way to make the dividing value settle to a desired point between two adjacent integers. Instead of having two complex controllers, ie. one for supplying dividing values to each of the two PLL circuits 10 and 11, a common controller 15 supplies dividing values to both. Dividing values can either be sent alternately to each PLL 10 and 11, or as alternate bursts of values to each PLL 10 and 11. The common controller 15 may also be shared between more than two PLL circuits for generating more than two frequencies simultaneously.

Title: Production of a monocrystalline layer
Inventor: LAERMER FRANZ
IPC: C23C16/24
Filed: 1999-01-21
Abstract: In order to produce monocrystalline layers made of conducting or semiconducting materials on porous monocrystalline layers made of the same material reproducibly and in a time-saving manner, a process is proposed in which an amorphous layer made of the same material is applied to the porous material and is converted by annealing into a monocrystalline layer. The material may be aluminium, silicon, silicon carbide or gallium arsenide, which may be applied by sputtering or by LPCVD or PECVD. The porous material may be partially oxidised before applying the amorphous material layer and the partially oxidised porous material layer is then thinned back until the porous material is exposed again in places. The monocrystalline material is thus in contact with the porous material at raised areas. The monocrystalline material layer may be joined to a carrier substrate and the porous material layer may be dissolved away and this technique is used to produce thin-film electronics. To produce the SOI structure the layer 4 is structured with a pattern of openings down to the porous silicon and the porous silicon is then completely oxidised.

Title: Accumulator for vehicle brake system
Inventor: REHN JAN-MICHAEL
IPC: B60T17/04
Filed: 1999-09-15
Abstract: Accumulator 2 comprises a flexible tubular diaphragm 10, an inner support element such as coil of steel wire 11, a preferably air permeable outer support element 12 and a surrounding enclosure 13. The accumulator is particularly adapted to be positioned in the hydraulic brake line (15, see Figure 1) between a main brake cylinder and a brake slip control device (3, 4, see Figure 1). In use, diaphragm 10 is pressed against outer support element 12 by fluid pressure from main cylinder 3. Upon activation of slip control device 4, fluid is removed from tubular diaphragm 10, which constricts against support element 11 (see Figure 4). Once the slip control device deactivates, diaphragm 10 returns to the position shown in Figure 2 with enclosure 13 preventing increased pressure from bursting support element 12. Thus, diaphragm 10 acts as a fluid reservoir. Diaphragm 10 may be made of ethylene propylene rubber, support element 12 may be perforated or sintered to be air-permeable and enclosure 13 may comprise metal braid. The accumulator is advantageous as all parts 10, 11, 12 and 13 are flexible, allowing easier fitting and accommodation in vehicles compared with rigid, prior designs.
