Patent GB-2227150-A (GB)
Title: Angling link
Inventor: SIANO MARIO FRANCESCO
IPC: A01K91/03
Filed: 1989-01-23
Abstract: Because of the nature of standard bottom attached float links they are harsh on fishing line, cannot be used to easily change floats, nor temporarily lock them in position on the fishing line. The soft quick change, temporary self locking, angling link, overcomes these problems. It comprises a flexible loop E that is large enough to pass over locking and any intermediate shot by pushing a small rubber sleeve F, or similar device up the loop. It will also temporarily lock the float in a desired position on the fishing line by moving the sleeve down the loop to slightly protrude from the base. "The link" being springy cushions the fishing line against violent movements. This device may also be used to attach other angling implements, eg. ledgers, swimfeeders, to the fishing line. <IMAGE>

Patent GB-2222975-A (GB)
Title: Friction welding
Inventor: SEARLE JOHN GILBERT
IPC: B23K20/12
Filed: 1989-09-15
Abstract: A friction welder has a reciprocator (1) with two chambers (7 and 8) each containing hydraulic fluid and separated by a dividing wall (6). A piston (14) on a driven rod (13) is slidable in a hole in the dividing wall and supports a carrier (28) to which a first component (36) is secured. Tow additional rods (9 and 10) extend through the chambers. Enlarged portions (11) thereof extend through holes in end walls (4 and 5) of the chambers. The additional rods are caused to reciprocate with fixed amplitude by Scotch cranks (23 to 26, and 31) driven by a motor (30). The relative phases of the Scotch cranks can be varied by axial movement of a sleeve (35) which engages splined shafts of the cranks, one of sets of splines (35) being helical and the other straight. When the additional rods reciprocate in unison they cause local variations in the interior space of the chambers which cause reciprocation of the piston. The amplitude of reciprocation of the piston is less than that of the additional rods but the force exerted is greater. The first component is held in frictional contact with a stationery second component (37) so that frictional heat is generated between them. When the cranks are 180 DEG  out of phase the piston ceases to move and the components become welded together. Reciprocation of the piston and associated parts is balanced by a balancer (2) somewhat similar to the reciprocator, while reciprocation of the additional rods and their extensions (16 and 17) in the balancer are balanced by pivoted counterweight (46).

Patent GB-909108-A (GB)
IPC: C10K1/00
Abstract: 909,108. Making sulphur. POWER-GAS CORPORATION Ltd. June 27, 1960 [June 26, 1959], No. 21930/59. Drawings to Specification. Class 90 A process for the substantially complete removal of hydrogen sulphide from an industrial gas with recovery of sulphur comprises scrubbing the gas in an absorber zone with an absorbent liquor and removing hydrogen sulphide, deriving a gas rich in hydrogen sulphide from regeneration of the absorbent liquor, passing gas comprising the remaining hydrogen sulphide through at least one bed of particles of iron oxide and/or manganese oxide to remove the remaining hydrogen sulphide in the form of iron sulphide and/or manganese sulphide, mixing the derived gas rich in hydrogen sulphide with free oxygen and with sulphur dioxide, passing the resulting gaseous mixture through at least one catalyst bed to effect formation of elemental sulphur by the reaction of hydrogen sulphide and sulphur dioxide, and recovering the elemental sulphur, in which process 70-85% of the hydrogen sulphide is derived from heating the iron sulphide and/or manganese sulphide under oxidizing conditions. Preferably the partially purified gas leaving the absorber zone is passed through at least one bed of particles of iron oxide or manganese oxide or both to remove substantially all the remaining hydrogen sulphide therefrom. Alternatively the partially purified gas leaving the absorber zone may be scrubbed with an absorbent liquor in a second absorber zone to remove substantially all the remaining hydrogen sulphide therefrom, the spent abosrbent liquor leaving the second absorber zone being regenerated with evolution of gas containing hydrogen sulphide and the evolved gas being passed through at least one bed of particles of iron oxide or manganese oxide or both to effect substantially complete removal of hydrogen sulphide therefrom. The absorbent liquor may be partially selective for hydrogen sulphide, e.g. a liquor having a higher H 2 S- absorption rate than a CO 2 -absorption rate. Specified absorbent liquors are aqueous triethanolamine, aqueous N-methyl diethanolamine, aqueous potassium salt of N-diethyl or N- dimethyl aminoacetic acid, aqueous sodium phenolate and aqueous tripotassium phosphate. A regeneration system comprising a steam stripping zone may be provided for spent absorbent liquor. Partially purified gas leaving the first absorber zone may have its carbon monoxide content catalytically converted to carbon dioxide. Iron oxide and manganese oxide absorbers may be regenerated by burning when their activity declines. The absorbent oxides may be employed as fixed or fluidized beds. Examples are given. Specification 719,056 is referred to.

Title: Automatic telephone ringing judgment control
Inventor: TUNG SHU-WEN
IPC: H04M1/715
Filed: 1991-06-06
Abstract: An automatic telephone ringing judgment control includes a phone call signal detector circuit, a master control circuit and a ringing judgment circuit (I, II), the phone call signal detector circuit intercepts a ringing signal from a telephone line on a private communication circuit and alters it to yield a ringing time signal for successive circuits, while the ringing judgment circuit (I, II) interprets the time sequence of different ringing signals and determines which of several communication devices e.g. telephone, facsimile, answering machine is to be connected. The master control circuit provides the power supply and indicator control and resets the system. As a whole, the automatic telephone ringing judgment control automatically detects telephone ringing signals and transfers them to the appropriate communication device. This automatic channelling is done without answering the call, so that communication efficiency is enhanced. Receiving functions of unwanted communication devices may be cut off to safeguard privacy. <IMAGE>
