Title: A method of forming aluminide coatings on nickel-base or cobalt-base super-alloys
IPC: C23C10/34
Filed: 1970-02-03
Abstract: Nickel- or cobalt-based superalloys are coated with Al by pack diffusion in a pack of sufficiently high Al activity to form preferentially an aluminide having a higher Al content on an atomic basis than that of the equiatomic monoaluminide, the coated alloy is removed from the pack, and is heat-treated at 1038-1204 C. to cause diffusion of Al from the coating to the alloy and to convert the coating into an aluminide having an Al content substantially corresponding to that of the monoaluminide. The pack may contain 5-20 wt per cent Al or Al alloy (e.g. A1:10-30% Si) 0À5-3% vaporizable halide (e.g. NH 4 Cl) and the balance inert refractory dispersant, e.g. Al 2 O 3 the pack diffusion may be performed in air at 649- 871 C., and the substrate may be pre-chromized conventionally.

Title: Continuous high temperature process for reclaiming reusable frying fats
IPC: A47J37/12
Filed: 1970-11-13
Abstract: Re-usable frying fat is recovered from frying fat contaminated with solid particles of food material by tangentially introducing a flow of food particle-containing frying fat at a pressure of 10-100 p.s.i. and at a temperature of 100-425 F into the upper cylindrical portion of a cylindro-conical shaped hydrocyclone and withdrawing the centrifugally separated solid particles of food material from the lower conical portion of the hydrocyclone and the substantially decontaminated frying fat from the upper cylindrical portion, the process being conducted substantially in the absence of air. The amount of air present in the separating zone of the hydrocyclone is controlled within the range of 0.5-1.0% of the volume of the fat by completely flooding the separating zone with frying fat during the start-up procedure. Preferred dimensions of the hydrocyclone are given. A number of hydrocyclones 33, 34, 35, Fig. 3, may be connected in series. Hydrocyclone 33 is fed from a circulating frying fat zone 30 via a line 31, the overflow from the hydrocyclone being recirculated through the zone 30 via lines 38 and 32. The overflow from hydrocyclone 34 is recirculated after being reheated through a heat exchanger 48 whereas the overflow from hydrocyclone 35 is fed back to the line 31. The underflow from the latter hydrocyclone is discarded.

Title: Incineration control
IPC: F26B23/02
Filed: 1974-09-13
Abstract: The specification discloses and describes a method and means for determining concentration of evaporated solvent in gases emitted from a drying oven and delivered to an incinerator, by simple measurement of the temperature of gases constituting products of combustion exhausted from the incinerator. By maintaining the fuel input to the incinerator constant and also maintaining the temperature of the gases entering the incinerator constant, the variation of the temperature of the products of combustion emitted from the incinerator with respect to a standard value reflects the variation in the concentration of evaporated solvents supplied to the incinerator. A valve means, responsively controlled according to the temperature of the products of combustion emitted from the incinerator, functions to regulate the admission of a diluent, such as air, to the oven, thereby regulating the concentration of evaporated solvent to a substantially constant and safe value and effecting regulation of a uniform temperature of gas products of combustion at the outlet of the incinerator.

Title: Vehicle coast control system
IPC: G08G1/00
Filed: 1975-04-04
Abstract: As a vehicle departs from a station, it senses at a reference position a wayside signal having a frequency indicative of the distance the vehicle should travel under tractive effort from the reference position to a coast position. A digital logic network on the vehicle includes an up/down counter which responds to the wayside signal for a predetermined time interval to count from a reference count level to a count level indicative of the distance the vehicle should travel under tractive effort prior to going into a coast mode of operation. A tachometer on the vehicle provides a speed signal having a frequency indicative of the speed at which the vehicle is traveling, with the number of pulses provided being a direct indication of how far the vehicle has traveled. The speed signal is used to count the up/down counter back down to the reference count level at which time tractive effort is interrupted on the vehicle, for allowing the vehicle to coast into the following station.

Title: Apparatus and method for use in developing wound coils
IPC: H01F41/06
Filed: 1976-03-05
Abstract: Monitor position of winding flyer in relation to a machine frame, substantially continuously generate signals indicative of flyer position, and control relative jump of coil forms and flyer in response to signals. Jump is initiated during predetermined portion of a flyer revolution while flyer is in "jump window" relative to turn receiver. Energy stored in lost motion mechanism contributes to acceleration of jump mechanism and same mechanism absorbs and stores energy as moving structure stops. Parts of coil forms are adjusted substantially equal distances relative to a geometric center and turn receiver and winding head undergo relative movement to maintain mutually aligned relationships. Fast and consistently responsive latch mechanisms insure jump during fraction of flyer revolution in different machine cycles. Jump mechanism urged against latches by pre-loaded spring mechanism for increased acceleration and to absorb prime mover force at end of jump stroke. Fast response diaphragm piston operated latch mechanisms perit initiation of jump stroke.
