Title: Electrical heater for conducting fluids - has current from conical coaxial electrodes passing through fluid to earth
IPC: H05B1/02
Filed: 1975-02-18
Abstract: The electrical heater, for delectrically conducting fluids consists of an insulating housing (10) with two electrodes between which the fluid flows. Current from the electrodes passes through the moving fluid to earth and thereby heats it. The outer electrode (21) has a funnel-shaped central hole corresponding to the outer tapered surface of the inner electrode (22) and the two electrodes are spaced to leave a gap (23) between for the fluid. Electrical connections are made to the electrodes via insulating leads and the inner conical electrode is held in place by an axial bolt. The heater reliably heats the fluid quickly.

Title: Uniformly loaded bowls for pressurising continuous webs of material - effective core seals permit working at low pressure
IPC: D06C15/02
Filed: 1975-12-23
Abstract: The pressurised chamber, in a bowl comprising a stationary core around which a hollow cylinder forming the working surface of the bowl rotates, and acting in conjunction with a second bowl, to apply a low pressure uniformity and continuously to a web of matl. moving at very high speed through the nip between the two bowls, is formed by sealing strips extending in grooves along the length of the core, and occupies only a small segment of the circumference of the bowl, such as subtends an angle at the centre of less than 35 degrees. Any fluid escaping from the pressure chamber into the cavity of the hollow cylinder, is sucked away through an exhaust bore in the core. Though working at very high speeds the low operating pressure and the lesser friction of a pressure chamber with a smaller arc, require a much smaller energy input.

Title: Milk powder pneumatic handling plant - with interrupted air flow to prevent sticking
IPC: B65G53/52
Filed: 1976-03-26
Abstract: The milk powder which is assumed to be greasy is transmitted along a feed pipe from a suction hopper to the storage or weighing hopper. The milk powder is discharged through a rotary valve and is supplied with pulsed air from the air valves along the line. The air pulses are timed to occur in synchronism with the opening of the rotary valve so that the flow is not continuous. Suction to the line is provided by the motor driven vacuum pump. The pulsation system prevents the greasy powder from clogging.

Title: Combustible prod. from domestic and industrial waste - by disintegration and homogenisation whilst mixing in oil sludge
IPC: C10L5/40
Filed: 1977-04-27
Abstract: Solid domestic waste matter contg. fibrous material with a low resistance to humidity and mainly combustible content, is mixed with a combustible liq. The mixt. is agitated so as to disperse the combustible liq. throughout the solid waste so as to reduce its resistance to disintegration, and then subjected to homogenisation to reduce the solid matter to a mass of particles. Finally the mass is impregnated with a combustible liq. to give a combustible prod. in the form of pulverised and homogenised particles. The prod. has a calorific value relatively high compared to domestic waste alone, and burns regularly. It burns readily in furnaces with spreaders and mobile hearths, and esp. with low grade coal in the proportion of 22% waste and 78% coal.
