Title: Conducting or catalysing a chemical reaction on a surface especially electroless metal deposition and catalyst systems used therein
Inventor: NEELY JAMES WATSON
IPC: H05K3/18
Filed: 1984-09-28
Abstract: In a process for catalysing or conducting a reaction on a surface there is formed on the surface a monolayer of positively charged polymer in the form of an aqueous solution or a stable aqueous colloidal dispersion of particles of particle size diameter less than 3 micrometers, the polymer having, distributed therethrough, active agent capable of reacting with, or catalysing the reaction of, said one or more chemicals upon contact, and this contact is then effected. In one aspect a catalyst system, which is especially useful for the electroless deposition of a metal, for example a conductive metal on a printed circuit board surface or through hole, is formed comprising a colloidal dispersion or solution of positively charged polymer and distributed throughout said polymer, catalytically active for the reaction of one or more chemicals, the particle size diameters of the polymer containing said active agent being less than 3 micrometres.

Title: Soil cultivating implements
Inventor: VAN DER LELY CORNELIS
IPC: B62D59/02
Filed: 1984-10-02
Abstract: In order that a relatively light and low-powered tractor 1 may be used in conjunction with a soil cultivating implement 2 that is located at the front of the tractor 1, the implement 2 is provided with a motor 25 in the form of an internal combustion engine. The implement 2 comprises a row of soil working members 5 and a ground roller 12. The motor 25 can drive both the soil working members and the roller 12 which latter tends to propel the implement 2 forwardly in the direction A, the transmission to both the soil working members and roller 12 incorporating independent change-speed gears. Although the implement 2 may be used alone with the tractor 1, it is described and illustrated as being employed with a rear-mounted soil cultivating implement 3 whose soil working members are powered by the tractor 1 and whose ground roller 12 is rotated by soil contact, this combination also including a seed drill 34 disposed, during operation of the combination, behind the rear soil cultivating implement 3. <IMAGE>

Title: A series switching regulator for power supplies
Inventor: COWSLEY DR CHRISTOPHER WILLIAM
IPC: H02M7/06
Filed: 1985-03-28
Abstract: A series switching regulator, for regulating a pulsating input voltage 5, has a thyristor 1 arranged to conduct only during periods when the load voltage 4 is such as to cause forward bias of the thyristor 1 before the input voltage increases from zero to a value set by a zener diode 10 and potential divider 7,8. When this value is reached, a transistor 6 shunts the gate circuit of the thyristor 1, thereby preventing it from switching on unless it is already forward biassed and conductive. The pulsating voltage 5 may be derived from an AC source and a rectifier, and two parallel regulators may be used to provide full-wave control of the AC supply. <IMAGE>

Patent GB-884945-A (GB)
Abstract: 884,945. Cable Clips. EMERY, E. F. June 15, 1960 [July 3, 1959], No. 22851/59. Class 36. Also in Group XXV] Relates to clips of the type comprising a ring-like member 12 of resiliently extensible material and a hook-ended connecting member 13. According to the invention the ring-like member 12 forms a hinged combination with the hook-ended member 13 and the portion 12b of the ring-like member engaging a hook of the hook-ended member to form the combination, is of such cross-section as to be capable of being passed through the open side of the hook with little or no deformation of the portion when the ring-like member is in one particular alignment with respect to the hook-ended member, such alignment corresponding to a non-operative assembly for the clip, but incapable of being passed through the open side without substantial deformation when otherwise orientated. As shown, the portion 12b of the member 12 is D-shaped in crosssection and the associated end of the member 13 is formed as a split sleeve 14, the slot 15 of which passes the smallest cross-sectional dimension of the portion 12b of the member 12 in the position of the parts shown, but which retains the portion 12b when the other portion 12a is engaged with the other hooked end of the member 13. In another arrangement, Fig. 3 (not shown), protruberances formed on the outer surface of the member 13 adjacent one hooked end thereof replace a rib 13c and together with the hooked end, provide the equivalent of the slot 15. The portion 12b of the member 12 may be elliptical in cross-section, Fig. 4 (not shown), or circular in cross-section with a channel longitudinally thereof, Fig. 5 (not shown). Specification 735,763 is referred to.

Patent GB-2233458-A (GB)
Title: Method of Inspecting constant-velocity joint
Inventor: KIKUCHI TOKIO
IPC: G01M13/02
Filed: 1990-06-22
Abstract: A "pass/fail" test on a constant-velocity joint A is performed by taking torque and tilt-angle measurements while the inner member b is driven in rotation. The measurements are processed to derive maximum and minimum torque values which are then compared with reference values, stored in memory 14, for a "model" joint. If there is a defect that causes the inner member b to be caught by the outer member a, a rogue torque maximum (Tz, figure 3) will occur. The inner b member is tilted to a maximum angle relative to the outer a, and measurements are made at predetermined rotational angular positions. <IMAGE>
