Abstract: ABSTRACT The present invention is directed generally to electri-cal connectors for providing interconnection between one or more printed circuit board panels and external electrical com-ponents.  When connectors are used under severe environmental conditions, printed circuit boards and their associated con-nectors must be coated with insulating liquids.  These liquids, however, are able to seep or wick into small crevices and apertures.  The present invention provides an improved con-nector not subject to wicking and seepage, as is the case with prior art connectors.  According to the invention, there is provided an electrical connector comprising a one-piece plastic body member having a main body portion, first and second exterior surfaces, and a plurality of spaced-apart, contact-receiving apertures extending between the surfaces. Each aperture has a narrow cavity region and a shoulder cavity region communicating with the narrow cavity region and cooperating therewith to define an offset shoulder surface. Electrical contacts are disposed in the apertures, each con-tact including a terminal portion, a shoulder portion and an active contact portion.  Each portion of the contact is shaped to correspond to the configuration of the correspond-ing cavity region in the connector, whereby the press fit of the terminal portion, the shoulder portion, and a plurality of raised ridges provided on the terminal portion of the contact define an irregular constricted and circuitous path through the aperture to provide an essentially liquid imper-vious juncture.

Title: Apparatus for cleaning submerged surfaces
Inventor: CHAUVIER FERNAND L O J
IPC: A47L5/00
Filed: 1978-10-11
Granted: 1979-07-24
Abstract: ABSTRACT     The invention disclosed herein relates to an apparatus for automatically cleaning surfaces submerged within a liquid, such as the walls and floors of swimming pools.  The apparatus comprises two suction passages in suction communication with a cleaning head that is releasably engageable with the surface to be cleaned and means, such as a flapper valve, for automatically transferring the flow of liquid from one passage to the other.  By this means, as the flow of liquid in a passage is halted, the kinetic energy of the liquid is transferred to the apparatus, causing it to be displaced along the surface.   The apparatus thus migrates randomly across the surface, cleaning it.

Abstract: ABSTRACT OF THE DISCLOSURE          A process is described herein for agglomerating and deodorizing pea flours, pea protein concentrates, or admixtures of pea flours or pea protein concentrates with other foodstuffs, said admixtures containing at least 25% by weight of said pea flours or pea protein concentrates, which process comprises: (a) charging said pea flours. pea protein concentrates, or said admixtures to a treatment chamber (b) agitating said charge while spraying same with water or suitable aqueous solutions or emulsions in the amount of about 5% to about 30% by weight of the dry charge, thereby to form bead-like agglomerates having about 12% to about 30% by weight of moisture; (c) heating the agglomerated flours, concentrates or admixtures to a temperature in the range of 185°-200°F., thereby to remove pea-like flavor and bitterness from the material: and (d) drying said agglomerated flours, concentrates or admixtures at a temperature in the range of 100°-130°F.  Desirably, step (d) of this process is carried out for a time ranging from about 20 to about 40 minutes.  The process produces a bland flavored, light-colored, free-flowing, bead-like agglomeration: pea flours, pea protein concentrates or of mixtures ??????? with other foodstuffs, and having a relatively high bulk density, e.g. up to 3 times greater than that of raw pea protein concentrate.  The products of this invention can be readily incorporated into food mixtures such as bread, cookie or pasta doughs, and the food mixtures containing such products can be readily handled in conventional equipment.  Foods containing such products are quite palatable, being free from pea-like flavour and bitterness; and provide a good source of protein.

Abstract: ABSTRACT OF THE DISCLOSURE             A single actuator unit is installed in an aircraft, for example, a helicopter, and is coupled to the control linkage from the pilot's stick to perform the functions of series actuation,trim actuation, artificial feel, control position sensing, control limits and, if needed, force boost. Although the device performs as a series actuator, it is installed in and connected to the vehicle surface control linkages in the conventional parallel actuator manner and therefore greatly simplifies control system installation and reduces problems associated with control rod vibration resonances normally encountered with series actuator install-ation.

Abstract: ABSTRACT OF THE DISCLOSURE           A solid state relay for interrupting current flow in a power distribution circuit is disclosed.  The relay includes a long time delay circuit which generates a first trip signal when the magnitude of the peak in-stantaneous line current rises above a pickup value I1 for a time period which varies as an inverse function of the magnitude of the peak instantaneous time current and which is determined by a first predetermined time current characteristic curve.  The first predetermined time current characteristic curve defines the desired operating characteristic of the relay over a first current range extending between the pickup current I1 and the higher current I2.  The predetermined time current  characteristic curve is determined by a multi-node RC element in the feed back loop of an operational amplifier which forms part of the long time delay circuit.

Abstract: ABSTRACT This invention relates to systems devised to rapidly heat an engine to facilitate the starting thereof.  Substantial reduction in vehicle operator effort, in size and quantity of structure required, and in reliance upon  moving parts of an engine for actuation of a device, are provided by the invention.  An accumulator reservoir (26) is coupled to an insulated fluid storage reservoir (28) which in turn is coupled to the engine cooling system.  A circuit (51) opens the valve structure (31), the accumulator (26) forcing fluid coolant out of the reservoir (28) into the cooling system, the circuit (51) disabling ignition of the engine until the coolant system is filled.  Upon shut-down of the engine, the circuit (51) after a time delay operates a pump (41) to move the coolant back into the reservoir (28) where the coolant is stored at an elevated temperature.
