Title: Method for thermochemical strengthening of glass articles
IPC: C03C21/00
Filed: 1968-05-25
Abstract: A sodium alumino-silicate glass article is strengthened by (1) heating the article to from 25 C. below the transformation range to within the transformation range for 4 hours and (ii) exchanging K+ for Na+ ions by contacting a surface with K+ ions at 50-150 below the strain point of the glass long enough for a compression layer 5 mm. deep to be formed in the surface. The glass consists essentially in wt. per cent of: Na 2 O, 10-20 Al 2 O 3 10-25 SiO 2 50-65. Other compatible oxides not exceeding 10 wt. per cent individually or 20% in total may be present, e.g. K 2 O, alkaline earth oxides e.g. MgO or CaO, ZrO 2 , PbO, P 2 O 5 , TiO 2 or B 2 O 3 . Not more than 1% Li 2 O should be present. Up to 1% As 2 O 3 may be added as fining agent. The strain points of these glasses are 550-600 C. and the annealing, points 600-650 C. The transformation range lies between these two points, and the heating in this range is preferably at 5-35 above the strain point, in an inert atmosphere, e.g. air. The K+ ions may be applied as a molten KNO 3 bath. Specification 966,733 is referred to.

Title: Small pupil binocular indirect ophthalmoscope
IPC: A61B3/13
Filed: 1975-08-05
Abstract: A binocular indirect ophthalmoscope of the type having a central reflecting prism and a pair of adjustable oculars. The instrument may be used in the examination of eyes having either normally dilated or small pupils. Small pupil capability is achieved by making the aperture of each ocular substantially larger than in conventional ophthalmoscopes. By moving the oculars outwardly from the center line of the observer's pupils, the observer views along an axis offset from the optical axis and utilizes the apex portion of the reflecting prism. In this manner, the observer's pupils may be imaged into a patient's pupil as small as 1.5 millimeters in diameter. The plurality of adjustments required in prior art small pupil ophthalmoscopes is thereby avoided.

Title: Device for low-loss variation of flow from a positive displacement pump by periodic interruption of the flow
IPC: F04B53/10
Filed: 1977-01-27
Abstract: The flow of fluid from a constant output positive displacement pump entering an outlet line directed to a consumer may be varied by periodically interrupting this flow and directing the flow instead into a zero pressure pump reservoir. This interruption is accomplished by a rotary shutter which periodically and alternately opens and closes the line to the reservoir. The line from the pump flows into two nozzles opening into opposite sides of the rotary shutter and directed toward one another. The rotary shutter comprises a shaft with two raised ribs thereon positioned to simultaneously open or close both of the nozzles, thus hydrostatically balancing the shaft. The edges of the raised ribs have cutting angles thereon for milling the opening of the nozzles during operation to produce an optimum gap between the rotary shutter and the nozzles. Only when the nozzles are closed is the flow directed into the outlet line to the consumer. An improved shape for the nozzle openings with respect to the rotary shutter edge is also disclosed.

Title: Composite silicate pigment
IPC: C09C1/00
Filed: 1977-03-17
Abstract: A composite silicate pigment is prepared according to a precipitation reaction when spherical, hydrous metal silicate particles are precipitated on the planar surfaces of clay particles having a platelet-type structure. The result of the precipitation reaction is to produce a product having an unexpected improvement in optical efficiency as compared with the optical efficiency of the clay component alone. When incorporated in a sheet of paper or the like, the spherical metal silicate particles act as spacers between individual clay particles to produce void volume or light scattering sites which in turn provide improved optical properties to the paper.

Title: Speed control for a universal electric motor
IPC: H02P25/14
Filed: 1978-01-20
Abstract: A first thyristor, under control of a speed setting provided in an RC circuit varies the phase duration of current supply to the motor during positive halfwaves of the a c supply, and a second thyristor controlled in accordance with the motor current provided through the first thyristor determines the phase angle during which current flows through the motor in the negative halfwave of the voltage supply, so as to maintain the speed at the set value under varying conditions of load. During positive halfwaves, a capacitor is charged to a voltage corresponding to the amount of current flow through the motor and during the following negative halfwave, the charge is increased at a rate set by an RC circuit, resulting in turning on the second thyristor early under heavy load conditions, and late under light load conditions, and indeed not at all under idling conditions.

Title: Spring reset mechanism
IPC: A01B61/04
Filed: 1978-03-17
Abstract: A safety trip mechanism for a ground working tool utilizes a roller pin engageable with a notched and spring biased latch to resist collapse of a toggle linkage and rotation of the tool supporting standard as obstacles are encountered by the tool. The roller pin is rigidly connected to one toggle link and spaced from the frame which supports the standard to reduce the breakout force acting on the pin. Flattening of the roller pin surface and wear between the pin and its latch are accordingly reduced to improve reliability of the trip mechanism and decrease maintenance.

Title: Method for simultaneously cleaning and skimming a vessel containing a liquid
IPC: E04H4/12
Filed: 1978-12-07
Abstract: This invention provides a valve by means of which a major portion of the suction flow of a swimming pool filtration system is channeled through an automatic cleaning device which cleans the floor and/or wall of a swimming pool, and a minor portion of the suction flow is drawn from the surface of the pool thereby to skim the surface. The valve has a main inlet opening connectable to the device, an outlet opening connectable to the filtration system and an auxiliary opening which is closed to some extent by a closure member to normally provide a restricted aperture through which the water drawn from the surface flows. The closure member is biassed closed by a spring located in a variable volume chamber which communicates with the interior of the valve between the auxiliary opening and the main inlet opening. When the restricted aperture is blocked by leaves or the like, the pressure in the chamber decreases, compressing the spring and allowing the closure member to open. The leaves or the like then pass through and the closure member closes again.
