Title: Preform for producing containers with an inner partition from a thermoplastic material
Inventor: BARRE PAUL LA
IPC: B29C49/06
Filed: 1998-06-12
Abstract: A preform (9) made of thermoplastic material and including a body (11) provided with an at least partially longitudinally extending inner partition (10). The preform is used for moulding and particularly blow moulding or stretch-blow moulding a container with a body having opposed portions defining hollow recesses with inwardly-directed convex surfaces, said portions being spaced apart by said inner partition. In a straight cross-sectional view, the body (11) has a non-circular outline with two opposed portions (a, b) separated by a minimum distance (d1) that is smaller than the distances between the other pairs of opposed portions of said outline. The inner partition (10) extends between said two opposed portions (a, b), and said distance (d1) is such that, relative to the periphery of the body (11) of the preform, during moulding, the inner partition (10) is transversely stretched at a rate equal to that at which the body (11) is transversely or peripherally stretched.

Title: Method for maintaining the charge capacity of traction battery modules of a hybrid electric vehicle.
Inventor: GREWE TIMOTHY MICHAEL
IPC: B60L50/15
Filed: 1998-10-30
Abstract: A hybrid electric vehicle includes a lead-acid traction battery made up of a plurality of series-connected modules. During operation of the vehicle, the traction battery is discharged for acceleration, and charged by an ancillary power source. The traction battery is desirably not fully charged at the beginning of a day's operation, so that overcharging cannot occur, so the battery spends long periods of time in a partially charged condition. When not fully charged for long periods of time, sulfation may reduce the charge storage capacity of the battery. A maintenance procedure takes place when the vehicle is not operating, in which one or more modules of the traction battery, but less than all the modules, are fully charged, then partially discharged. The full charging tends to reduce sulfation in the particular module being maintained, and the partial discharge restores its charge condition to that prior to the full charge. Each of the modules is eventually maintained by a programme d controller. The charging energy comes from an auxiliary battery, and the discharge energy is returned to the auxiliary battery, so there is little net loss of energy. If maintenance procedure is interrupted before full charge of a module, that module is scheduled for the next maintenance. If the maintenance is interrupted before partial discharge, the partial discharge is accomplished by equalizing the voltage of the battery modules.

Title: Packing element back-up system incorporating iris mechanism
Inventor: LORN SCOTT MACDONALD
IPC: E21B33/12
Filed: 2016-04-20
Abstract: An annular sealing assembly and method are disclosed. The assembly includes a mandrel and an expandable element disposed around the mandrel which expands to seal against the inner diameter of a tubing or casing string. The expandable element seals the mandrel from the annulus between the mandrel and the tubing string. The assembly includes at least one back-up element having a plurality of pivoting blades circumferentially secured in a ring around the mandrel. The back-up element is capable of radially expanding and contracting upon longitudinal movement along, and engagement with, a generally ring-shaped ramp.

Title: Oil and water separator, esp. for bilge pump - has photoelectric cell in suction line and electronic circuit
IPC: B01D17/02
Filed: 1977-12-08
Abstract: The functioning of a fluid separator depends upon the difference in transparency of the fluids. A light-sensitive circuit is used to monitor the transparency of a fluid passing along a pump suction line, and a relay either starts or stops the pump. The light source and the detector may be installed in the pump line, or inside the pump itself, or the pump suction line may be interrupted by a section through which light can pass; the light sensitive element and the light source being positioned outside this section. The pump may be operated by an electronic circuit instead of a relay. The system is used for the protection of the environment by providing an automatic control of the bilge pump jettisoning water coming in along the screw shaft, so that as soon as oil appears in the line, the pump is switched off and a signal is put out. The control of industrial operations may be carried out by similar means.

Abstract: The pressure compensator for a fluid pressure system has an elongated resilient bag connected to system pressure and itself contained in a rigid elongate cage. At one end the cage is a removable bung (32) held in the closed position by the bag when inflated. The bung is removed when the bag is deflated by pushing in and rotating the bung, then pulling it past the lip (39). Manual pressure against the bung from outside the cage reveals whether the bag is in order. If the bag is deflated due to damage the bung gives way and can be removed for assembly of a new bag.

Title: Coffee bean roasting process - with two separate drying stages using fluidising gases at differing temps. and velocities
IPC: A23F5/04
Filed: 1979-07-09
Abstract: Continuous dry rotating of green coffee beams is effected by progressively and continuously moving and agitating dry green coffee beans in a fluidised bed successively through first and second separate roasting chambers. In the first chamber the beans are contacted with a dry high velocity gas which fluidises the beans. The gas temp. is 440-470 degrees F. This effects a partial roasting of the beans and expansion of the cellular structure. In the second chamber the beans are contacted with an independent dry roasting gas stream which fluidises the beans. This gas stream is at a lower velocity and higher temp. than the first stream. This stabilises the open structure of the beans and darkens them without burning them. The temp. is 515-545 degrees F. The beans are finally cooled. Method produces a high soluble solids yield, low density, roasted coffee prod.

Title: Prepn malonic dinitrile from acetonitrile and cyan - ogen chloride
Filed: 1980-08-07
Abstract: Reaction is carried out in the gaseous phase at 740-780 degrees C; the reaction mixture (contng. malonic dinitrile, and as impurities, maleic and fumaric dinitriles), is either 1) subjected to a Diels-Alder reaction to convert the maleic and fumaric dinitriles to the corresponding Diels-Alder adducts (which may then be separated from the malonic dinitrile); or 2) subjected to selective hydrogenation using a calculated amount of hydrogen and a hydrogenation catalyst, so as to convert the maleic and fumaric dinitriles to succinic dinitrile, which may be separated off by fractional distillation. The process gives a higher yield of malonic dinitrile than prior art processes, with a purity of at least 99%.
Patent NL-8120059-A (NL)
Title: Circuit selecting highest amplitude of two AC signals - uses open loop operational amplifier, to which are applied summed AC signals, with zero crossing counter and weak signal filter
IPC: G01R23/00
Filed: 1981-03-17
Abstract: Tram car communication is provided through the lines in information zones, each zone having a different carrier frequency. The circuit selects the carrier frequency which has the greater amplitude using simple level detector. The signals corresponding to two frequencies are summed by an open loop amplifier and the zero crossings at the output are counted. The counter output is used to switch into circuit an appropriate filter to reject the lower amplitude signal. The period of the square wave delivered to the counter is directly proportional to that of the signal having the greatest amplitude, assuming that the counter has a predetermined count capacity. Thus, the device remains insensitive to the weakest signal and the signal having the greatest amplitude is always considered to be the useful one.
