Abstract: ABSTRACT     The invention relates to air heaters and provides a means by which the operation of heat exchangers therein can be sustained at an optimum efficiency. The invention proposes the incorporation of a preheater (16) for incoming unheated air which can be selectively thermally coupled to heated air in an outlet duct (12) from the heat exchanger (4). During normal operation the heated air bypasses the thermal coupling, but when the temperature of the incoming unheated air is particularly low, the coupling is made and the incoming air thereby preheated to ensure efficient operation of the heat exchanger.

Abstract: ABSTRACT                 SPLAYED ROLL FOLDER FOR ADHESIVE APPLICATION          An apparatus and method for forming one or more pleats in a continuously advancing sheet of indeterminate length are provided.  The apparatus includes a first roll, over which the sheet passes while a streak of adhesive is laid upon a selected strip of the sheet, and a composite roll, to which the sheet passes as a reach under selectively varied tension.  The composite roll includes a parallel roll and an inclined roll which is inclined at a pleat angle to the parallel roll and is driven by rolling contact with the parallel roll while passing through a pinch zone at the apex of the pleat angle which is 0.25° to 5°.  The periphery of the inclined roll may vary from a right circular cylinder to a right circular cone with its peripheral surface at a bevel angle to the circular side thereof.  The bevel angle is preferably one half of the pleat angle.  The pleat is formed by gathering the strip into the circularly covering gap between the inclined and parallel rolls and then lightly compressing the pleat between the sides of a circumannular recess between the rolls.

Title: Plunger lock for manual dispensing pump
Inventor: FORD JOHN M B
IPC: B05B11/00
Filed: 1982-12-13
Granted: 1985-06-04
Abstract: PLUNGER LOCK FOR MANUAL DISPENSING PUMP              Abstract Of The Disclosure The plunger of the pump has an axial lock by which the plunger can be locked down in its fully depressed position during periods of non-use and a rotary lock for preventing inadvertent rotation of the plunger out of its locked down mode.  The rotary lock includes a pair of yieldably spreadable arms which circle the collar of the pump and latch against one another in overlapping, embracing relationship so that the lock is held tightly on the collar against rotation relative thereto.  A locking bar integral with the arms and of essentially rigid construction projects up out of the plane of curvature of the arms and has a saddle-like notch at its uppermost tip which complementally receives a portion of the spout associated with the discharge head of the plunger, thereby rendering the plunger rotatively immobile relative to the collar.  If desired, hinge lines which permit the arms to flex toward and away from one another during installation and removal of the rotary lock from the pump may be intentionally designed to be in a sufficiently weakened condition as to permit at least one of the arms to be torn free from the remainder of the lock in order to release the latter from the pump.          Mating teeth of optional configurations may be provided on the interior portions of the arms and the exterior of the pump collar to promote tight retention of the lock on the collar.

Abstract: METHOD FOR FABRICATING                A SEMICONDUCTOR DEVICE            Abstract A method for forming a shallow and highly concentrated arsenic doped surface layer in a silicon bulk region includes the steps of forming an arsenic doped polysilicon layer in contact with a preselected area of a bulk region surface in which the surface layer is to be formed and completely oxidizing the polysilicon layer at a rate exceeding the rate at which arsenic diffuses in the bulk region.  Since arsenic has a relatively high silicon/silicon dioxide segregation coefficient and the oxidation rate exceeds the arsenic diffusion rate, arsenic accumulates at the silicon dioxide/silicon interface during oxidation, and nearly all of the arsenic in the region of the polysilicon layer above the preselected area is driven into the bulk region surface by the oxidation to form an impurity layer having a very high surface concentration of arsenic.

Abstract: Rock-to-Lock Connection Arm-To-Blade Abstract Connector apparatus is provided for permitting rapid connection and disconnection of a wiper blade from a wiper arm.  The blade portion of the connector includes a pair of spaced apart parallel slots.  To accommodate dif-ferent styles of wiper arm ends, two longitudinally spaced pins are provided on the blade.  One of the two pins is used with an arm end having two parallel spaced tabs with for-wardly facing pin slots and the other pin is used with an arm end having two parallel spaced tabs, forwardly facing pin slots and rearwardly spaced guide portions.  Both of the last named two arm ends have structure for retaining the blade on the arm end even when the blade and arm are lifted from the windshield.  In an additional embodiment, one of the two pins is removable to accommodate attachment of the side pin of a side pin style connector.  Since the arm is secured to the blade along two transversely spaced planes, the chances of rollover of the blade relative to the arm is minimized.

Abstract: Abstract of the Disclosure Apparatus for measuring the color, brightness and opacity of a moving web in which light from a plurality of sources is directed towards and through a moving web.  Light reflected from the surface of the web is conveyed by a plurality of light pipes to a first photodetector array located at a point remote from the web.  A circular variable bandpass filter varies the wavelength of the radiation reaching the detector substantially continuously through the optical spectrum to produce a detector output which periodically scans the optical spectrum.  The detector outputs at various wavelengths are weighted by a microcomputer to produce brightness and X, Y and Z tristimulus values.  Light transmitted through the web is conveyed by a plurality of light pipes to a second photodetector array also located at a point remote from the web.  The photodetector is also monitored by the microcomputer to provide an indication of the opacity of the web.

Abstract: ABSTRACT OF THE DISCLOSURE           A resettable contact closing device opens a load circuit connected to a power line protected by a ground fault interrupter circuit, if the neutral conductor is broken.  The contacts are closed by a mechanical reset actuator only if a solenoid is energized by a potential proportional to the line-to-neutral voltage to hold the actuator in a contact closing position.  If the neutral conductor is broken, the solenoid will not be energized and the contacts, and hence the power line to the load circuit, will be opened.
