Title: Viscous syrup and water blender - has hollow pistons in bores in housing under spring load
IPC: B01F5/00
Filed: 1974-09-20
Abstract: Blender for diluent and fruit-containing syrup provides precise portions by means of a housing whose centre bore is hunged at both ends to enclose a chamber which can be vented at one end through a valve in one bung and drained at the other through the bung at the far end of the bore. The cooled water diluent enters the chamber through an entry higher up than the entry or entries provided for the viscous syrup specified. Bores lead from these respective entries at right angles to the chamber axis and pass through the housing and accommodate hollow pistons, each with outlets for the respective fluids. The springs opposing the piston movement thrust off the lid on the housing. The pistons should travel along machined guide ways provided on crosspins for the purpose.

Title: Snow chain tensioning system - uses clip fitting channel section wedges to shorten separate links
IPC: F16G15/00
Filed: 1975-02-12
Abstract: The chain to be shortened has one of the liks twisted through 90 deg. so that a special wedge (2) can be clipped into the free space in that link. The wedge has profiled ends and wedges joined by a central narrow section. One end of the wedge sits snugly in one end of the chain link while the other end has concave face. This effectively forms a shortened chain link when the link is swung back into line with the chain again. The whole chain is shortened by the length of the wedge, and this process can be repeated with other wedges and are held in place by the chain tension.

Title: Implosion generator producing acoustic impulse - using main and branch liq. jets driven by magnetic field at high speed producing hollow space
IPC: G01V1/133
Filed: 1975-04-18
Abstract: The implosion generator produces an acoustic impulse. The generator produces a main liquid jet which is introduced at very high speed along a pre-determined trajectory into a liquid body. The liquid jet is driven by a magnetic field which is practically stopped for a brief moment. The speed selected is sufficiently high to produce a hollow space with subsequently an implosion being produced. The main liquid jet is subdivided into at least two branch liquid jets with the branch jets being diverted into a plane about vertical to the trajectory of the main jet. The branch liquid jets are offset in relation to each other by about 90 degrees.

Title: Ignition advance circuit for IC engine - optimises advance angle according to shaft motion by electronic means
IPC: F02P5/155
Filed: 1975-06-19
Abstract: The ignition advance circuit for an internal combustion engine, produces the optimum advance angle and distributes the spark voltage. A signal is derived from the motion of the crankshaft corresponding to the point of maximum advance, which is determined by the angle alpha. A potentiometer allows manual adjustment. The advantage of optimising the advance angle lies in increasing the efficiency of the engine and reducing various kinds of pollution produced by the engine. An electronic computing system is used to calculate the optimum advance for all operating conditions.
