Title: Timing generator circuit for telephone systems - has processor switched over from main to standby clock generator when former fails
IPC: H04L7/00
Filed: 1973-07-03
Abstract: The timing generator circuit, for controlling processors in telephone systems, has two clock-pulse generators (H1, H2) connected to a switching circuit (A) that connects one generator through to the processor (UT). The switching circuit output is monitored (F) for errors or failure and the result used (B) to switch the switching circuit over from the faulty clock generator to the second, standby generator. Both clock generators are coupled to a display circuit (V), which enables an operator to check the correct functioning of either generator. With this timing circuit, the failure of one generator does not result in the whole processing system coming to a stop.

Title: Cold chamber die casting machine - for non-ferrous metals, using double plunger with inert-gas boost
IPC: B22D17/32
Filed: 1973-10-29
Abstract: The molten metal is forced into the die by a hollow outer plunger (I) the bore of which forms a cylinder contg. a second, coaxial plunger or piston (II). Inert gas is fed into the inner cylinder and functions as a 'cushion' during the initial part of the feeding stroke and then as a booster at the end of this stroke. The inert gas is fed into the inner cylinder at a press. of pref. 50-500, esp. 100-150 bar, and piston (II) is free to slide in the bore of plunger (I) without coming into contact with the molten metal. Provides reduced stress on the dies, giving longer die-life, and sounder casting due to the efficient boost.

Title: Elevator-cooler for dry foundry sand - which is conveyed by compressed air up water-cooled column and into a hopper
IPC: B65G53/12
Filed: 1974-10-01
Abstract: Elevator-cooler for dry foundry sand, employing a column up which the sand flows and then passes into a hopper from which it can be removed, the column being provided with a sleeve for the circulation of a coolant, and with a fluidising nozzle, supplied with a compressed gas, in the lower part of the column.

Title: Heating thermosetting materials using live steam in the mould cavity - to reduce heat transfer cycles and eliminate mould tool cooling
IPC: B29C33/10
Filed: 1977-02-04
Abstract: Cycles for moulding particles of thermosetting materials, esp. polystyrene are reduced by vacuum charging to feed particles into a mould cavity in a tool having passages and filters for circulating live steam through the material in the cavity to provide the heat for curing. At least the major part of the heat transfer required by the material is provided by the steam, allowing the mould tools to be operated at relatively low temps., obviating mould cooling between cycles. Mould residence times may be reduced by 70-90% compared with processes involving heat transfer by conduction from the cavity surfaces. The tool is also subjected to less thermal stress.

Title: Filter apparatus for removing dust from air streams - using two or more filter media in layer
IPC: B01D46/10
Filed: 1977-02-08
Abstract: The filter apparatus employs materials with a natural electrostatic action, high polymer plastics with different textures. They are arranged symmetrically in the filter. The outer layers of the filter comprise thin sheets is which the constituent filaments are arranged in a regular geometric fashion. Between the outer layers is placed a mass of material in which the filament may be only approximately regular, but the mass has sufficient thickness to give the filter a good dust retention capacity. The combination of the two types of material produces the filtration efficiency of the geometric sheet together with the retention capacity of the thicker mass of material. The symmetrical arrangement of the filter combined with the fact that an auxiliary filter cloth is unnecessary means that the air flow can pass through the filter in either direction. The filter ca be used in systems where the filter is washed automatically without suffering damage. Any situation where fine filtration of air is required either alone of as a prefilter.
