Title: Reinforced mouldable semi-fabricate - from binder impregnated mat of mineral fibres by impregnating with aqs vinyl polymer suspension
IPC: B29C/
Filed: 1971-10-21
Abstract: Thermally mouldable, mineral fibre-reinforced semi-finished products are produced by (a) impregnating mats of long material fibres reinforced with a binder with an aqs. suspension of a vinyl polymer with >=40% dry material, the polymer having a softening pt of at least 70 degrees C, (b) drying the impregnated mats, and (c) heating them to form a continuous layer of vinyl polymer. The binder of the mats of mineral fibres does not dissolve in the vinyl polymer and the amt of the suspension of vinyl polymer absorbed by the mats is sufficient to give a dry semi-finished product contg. 40-70% wt vinyl polymer. Mats with wts up to 1500 g/m2 can be rapidly and continuously impregnated with the vinyl polymer in a single operation, with complete elimination of occluded air. The wt of the mat per sq.m. can be varied as desired. The products are flexible and give articles with excellent mechanical props.

Title: Motor vehicle A.C. generator voltage regulator - has second rectifier supplying regulator and preventing battery discharging over excitation coil during standstill
IPC: H02J7/16
Filed: 1973-07-04
Abstract: The voltage regulating system for A.C. generators in motor vehicles has a three-phase diode bridge coupled to the generator output windings, and its rectified output is passed to a batter. A second bridge is led off from the first and supplies the generator excitation winding and regulator. The second bridge prevents the battery discharging over the excitation winding when the vehicle is stationary. the regulator controls the excitation winding current and has two positive terminals, the first one being connected to the second rectifier out and the second one over contacts to the battery. A protection circuit, consisting of two series-coupled diodes, is connected across these two terminals to protect the system if the generator-to-load ead or the regulator-to-battery lead should break loose. The second diode may be bridged by a resistor.

Title: Thermoplastic sheet preform for cast mould tools - for reducing cost of producing experimental moulds
IPC: B29C33/38
Filed: 1975-02-18
Abstract: Moulds are made by prefabricating a model from readily shaped materials, thermoforming a plastic sheet on to the model ot obtain an inverted copy of the model profile, and subsequently using the sheet to line a fluidised bed mould for casting finely divided concrete to obtain a replicate of the model durable enough for use as a tool for moulding plastics materials. The sheet is coated with a layer of releasing agent to remove the sheet from the cast mould. The process is suitable for making male, cavity or complementary mould tools. It is quicker and cheaper than machining original model from metal or other materials hard or heat resistant enough for use directly as moulding tools. Models can be adapted and modified tools cast from fresh thermoformings to develop tool shapes from faults on trial mouldings.

Title: Undersea pipe laying system - uses belt drive for pipe in housing with pendulum suspension and pipe tension sensor
IPC: G05G25/00
Filed: 1975-05-14
Abstract: Pipes being laid on the sea bed are mounted on a barge during preparation and welding. Tension of pipes must be kept constant in spite of state of the sea. This is performed by suspending a housing from a base which is mounted on the deck of the barge. Tension sensors control the rollers and conveyor belts which are used for moving the pipes. A pipe (4) is supported between two belts (2, 3) in a housing (1) with a rectangular chassis (6). This is suspended (7) by non-rigid cables from a rectangular base (5) on the deck (8) so that the housing moves as a pendulum. Longitudinal movement between guides in the sides is permitted by deformable rings in the front and rear which operate in tension and are equipped with potentiometric comparators which control movement of the belts.

Title: Ceiling mounted indirect air heater - has combustion chamber and outer jacket of same shape for smooth flow
IPC: F24H3/08
Filed: 1975-05-14
Abstract: A ceiling mounted heater has an outer jacket (12) formed from a dished upper part (14), a cylindrical centre portion (16) and a dished lower part (15). A cylindrical neck (17) at the top contains a fan (22) which draws air in at the top and discharges it through a neck (33) at the bottom. A combustion chamber (13) suspended within the outer jacket is of the same shape as the jacket so that the annular space (25) between them through which the air flows is of a constant cross-section. This improves air flow and reduces losses. The combustion gases flow out of the combustion chamber through secondary heating coils which are spirally would within the central part of the annular air passage before leaving through a flue outlet (42).

Title: Method of moving concrete wall shuttering - has pivotal bracing and work frame on climbing pivotal panel
IPC: E04G11/30
Filed: 1975-07-08
Abstract: A module (A) height panel (2) has a double module depth bracing frame (1), the latter trailing the former by module depth when in the pouring position to provide a counter couple, with its lower terminal leg (31) bearing on the previously formed wall (4). Climbing is effected, once the currently poured panel has matured, by lowering the bracing frame (1) so that it fully trails the shutter panel (1), then rotating the panel through 180 deg. about a horizontal axis in its leading edge: the bracing panel in the meantime having freely and pivoting (22) about the trailing panel edge, to the effect that once the panel (2) is inverted the bracing (2) is automatically in position for the succeeding pour. The cycle would then be repeated.
