Patent number: 4763313Abstract: A plural-orientation watch mount which includes a receptacle adapted to retentionally receive a subject wrist watch, a carrier adapted for mountability onto an independent structure of interest, and means for the selective orientation of the receptacle onto the carrier.As preferably embodied, the subject mounting means more specifically includes a dovetailed male connection between subject carrier and receptacle. Advantageously, two grooves may be configured at essentially 90-degrees relative to each other so as to accordingly provide mount fixations at essentially 90-degree intervals.The receptacle itself may, in turn, be more specifically designed so as to define a surface configuration to receive a watch of the pin-tabbed variety. A first side of the receptacle would then preferably be adapted for an inserted-pin securement of a first tabbed-side of this type of watch, with an opposite second side of the receptacle being sized for a press-fit securement of an opposite second tabbed side of the watch.Type: GrantFiled: March 13, 1987Date of Patent: August 9, 1988Assignee: Partz PartnershipInventors: Jerry A. Greer, Lisa J. Lowe

Patent number: 4759554Abstract: A mechanical face seal comprises a first seal face member associated in fixed relationship and sealed with respect to one component, a second seal face member associated in fixed rotational relationship and sealed with respect to a second component and a third seal face member interposed between the first and second seal face members. Springs are provided to urge the second seal face member towards the first seal face member and maintain the first, second and third seal face members in sealing engagement. The sealing faces of the first, second and third seal face members are inclined, so that the first and second seal face members impose a radial load on the third seal face member. Two such seal assemblies may be provided co-axially of one another to provide a double seal.Type: GrantFiled: October 29, 1986Date of Patent: July 26, 1988Assignee: Crane Packing LimitedInventors: John Kemp, David J.

Patent number: 4485729Abstract: A method of controlling an atmosphere in an enclosure (12) to which gas (40) is being supplied comprises the steps of monitoring (53) atmospheric pressure within the enclosure and the rate of gas flow to (52) or from the enclosure, comparing these parameters (62) with adjustable set points to obtain error values and adjusting inflow (50) and exhaust (51) valves for the enclosure in dependence upon the error values. A preferred method includes the intermediate steps of deriving from the error values, target positions for the valves. Also disclosed is an installation incorporating a control system for carrying out the method.Type: GrantFiled: February 2, 1984Date of Patent: December 4, 1984Assignee: Commonwealth of AustraliaInventors: Mark D.

Patent number: 4354691Abstract: A wheel chair propulsion device particularly for use by quadriplegics that includes an annular ring smaller in diameter than the large wheel of a conventional wheel chair and having a plurality of spaced apart recesses in a surface thereof. The ring is fastened to the wheel of the wheel chair in co-axial relation therewith and spaced outward therefrom. A lever is pivotally mounted on the wheel chair axle and an opposite end of the lever projects above the conventional arm rest on the wheel chair. A drive mechanism is mounted on the lever arm and positively engageable with the annular ring for rotating the same and disengageable therefrom to allow free rotation of the wheel. The drive mechanism comprises a lug movable into and out of the recesses in the ring in response to movement of the lever in a direction transverse to the plane of the wheel and resilient compressible means which is compressed by movement of the lever in a direction to move the lug into a recess in the ring.Type: GrantFiled: August 28, 1980Date of Patent: October 19, 1982Assignee: Queen's University at KingstonInventors: Gerald A. B. Saunders, Philip J. Lowe

Patent number: 4332832Abstract: A rehydratable dry animal food is prepared by preparing a mix of comminuted, heat-treated meaty materials, fat and pregelatinized starch carbohydrate binder, forming the mix into pieces and drying the pieces to form permeable solid pieces which rehydrate to a paste-like material of heterogeneous texture. The mix preferably contains bone fragments, which can be softened by autoclaving and which lend a desirable flaky texture to the rehydrated product. The pregelatinized starch carbohydrate binder may be pregelatinized potato powder or cereal products in which the starch content is in pregelatinized form or other starch containing products in which the starch component has been pregelatinized. Typical mixes contain 70-80% meaty materials, 10% fat and 10-20% of said binder. The pieces may be extruded under low pressure or extrusion-expanded to give an open texture.Type: GrantFiled: January 7, 1980Date of Patent: June 1, 1982Assignee: Mars LimitedInventors: Keith Buckley, Ian E. Burrows, Philip J. Lowe

Patent number: 4325928Abstract: Phosphate rock can be heat treated at 380.degree.-600.degree. C. to convert the organics to filterable carbon and the rock converted to wet process phosphoric acid of reduced color and with reduced foaming. Rocks having high acid soluble organics but low total organics, and rocks containing a high content of acid insoluble heat labile iron sulphide are especially suitable.Type: GrantFiled: February 22, 1980Date of Patent: April 20, 1982Assignee: Albright & Wilson LimitedInventor: Edward J. Lowe

Patent number: 4215351Abstract: In a potentiometric chart recorder, the speed of the chart motor 22 is, in one mode of operation (AUTO) selected by a switch 32, varied between two values in dependence upon the rate of change or slope of the input signal at 10 as detected in a detector 30. The slow speed is obtained by intermittent operation at the fast speed, and during the non-operative periods power-consuming circuitry e.g. 16, 18, 26 is switched off by a switch 40.Type: GrantFiled: September 21, 1978Date of Patent: July 29, 1980Assignee: National Research Development CorporationInventor: David J.

Patent number: 4180592Abstract: Blood, red blood derivatives or blood-containing materials such as liver are decolorized for use in food or animal food products by oxidants such as hydrogen peroxide or calcium or sodium peroxide. Excess peroxide can be removed and a desirable color achieved by adding further blood, blood derivative or meaty material. Reaction with the peroxide can be facilitated by a pH reversal process in which the pH is raised or lowered by at least 2 units and then restored. Heat or a combination of heat and pH reversal can also be employed. Flavors and other additions added to the blood or other material before decolorization are locked in the resulting product. The decolorized material can be canned as a mince-like product or mixed with other foodstuffs.Type: GrantFiled: August 1, 1977Date of Patent: December 25, 1979Assignee: Mars LimitedInventors: Keith Buckley, Alan Vernon, Philip J. Lowe

Patent number: 4168322Abstract: A protein food product is described, together with a process for making it. Whey protein derived from milk is adjusted to a pH of 6 to 9 and coagulated by heat, thereby giving a firm, non-brittle material which is useful as a protein food in its own right, or as a matrix for composite products, or in the manufacture of pieces resembling meat offals such as kidney, to improve the texture of meat-containing mixes, for example of sausage type, and for other food products, all of which are useful as protein foods for animals and also for human beings.Type: GrantFiled: August 17, 1977Date of Patent: September 18, 1979Assignee: Mars LimitedInventors: Keith Buckley, Philip J.
