Title: Tool for fixing threaded tubular rivets - uses levered rotation of bolt screwed into rivet to axially compress rivet
IPC: B25B27/00
Filed: 1973-12-28
Abstract: The bolt (1) or threaded spindle is screwed (12) into a hexagonally sectioned sleeve (4), the nose of which incorporates a thrust block (7), this latter being free to rotate w.r.t. the sleeve by a ball bearing (6) and permitting free passage of the spindle. Engagement of the rivet (2) on the spindle is followed by rotationally tightening the thrust block (7) onto the work surface. The spindle is held locked by lever (3) and the sleeve raised by lever (5). This raises the lower part of the rivet and causes a radially outward deformation of the thin walled section of the rivet.

Title: Digital quotient meter with numerical readout - has coupled and compared counters for pulse generator
IPC: G01P3/489
Filed: 1974-02-28
Abstract: The meter is used in an automatic test and diagnostic equipment as a phase meter for ignition advance measurements and also as a tachometer. A control circuit receives two variable amplitude signals of which the quotient is required. A pulse generator has two pulse train outputs which are switched by the control circuit. The switches permit the pulses to increment two counters during respective time intervals. Pulses at the output of one counter increment a second counter and provide a reset to zero signal from a pulse generator. When the value of this count equals that of the other counter a comparator increments a fourth counter to give a count proportional to the quotient.

Title: Clip for connecting wires in spring suspensions - has two part fastening strip preventing squeaky displacement of wires when stressed
IPC: F16B2/24
Filed: 1975-09-12
Abstract: The wire-connecting clip (10) consists of a strip (15) of metal or plastics which firmly encloses the contacting wires and is mounted at one end (14) of a plate (13) whilst a second strip (17) is fastened to the other end (16) at an angle to the first strip (15), and engages round one of the two wires (11 or 12) at a distance from the connecting point.

Title: Stabilised technetium-99m generators - produced by adsorbing a molybdate and chromate soln on alumina
IPC: G21G1/04
Filed: 1976-03-18
Abstract: Technetium-99m generators are produced by (a) forming a soln.contg. Mo99-molybdate and a chromate or bichromate, and (b) introducing the acidic soln. into a column packed with Al2O3. The Mo99 in the generator decays to Tc99m, which can be eluted in the form of a pertechnetate soln. for direct scintigraphic use or for labelling organ-specific transport substances. The (bi)chromate is adsorbed with the molybdate and inhibits the radiochemical redn. of the latter without itself being eluted; it increases the capacity of Al2O3 to adsorb molybdate by about 30%; it stabilises the acidic molybdate soln.; and its yellow colour gives an indication of the charging state of the column and eliminates the risk of molybdate breakthrough.

Title: Roasting or sintering material in a shaft furnace - using combustible gas without local overheating
IPC: C04B2/12
Filed: 1976-06-18
Abstract: In roasting or sintering material in mass in a shaft furnace, the material is introduced into the furnace via the mouth together with a certain amt. of hydrocarbon-contg. solid fuel to satisfy part of the thermal requirements and air is introduced via the charging orifice. The process is characterised by the addn. of a mixt. of a combustible gas and and inert gas, non-burning at the temp. of the charging orifice, at the periphery of the furnace shaft and at a distance corresponding to at least 5% of the total height of the furnace shaft below the flame zone. The process is used for roasting or sintering limestone, dolomite or magnesite in mass either as particles or pieces. The process can be adapted to large dia. shaft furnaces. Solid fuel is mixed with a combustible gas, such as natural gas, without the material being overheated. Existing coke/coal furnaces can be easily converted to use this process. Burners requiring constant surveillance are not needed. The flow of the gases is easily controlled and the roasted material is of uniform quality. A favourable heat balance is obtd. esp. since part of the exhaust gases is used.
