A method and apparatus for applying covers to seat cushions and the like includes means to maintain the cushioning material under compression within the cover as the cushioning material is moved into the cover.
摘要:
An apparatus and method for applying covers to seat cushions, including a frame cushion support which is rotatable between a portion in which the cushion covered thereby is compressed to facilitate placing the cover over the cushion and a position which provides access to the bottom of the cushion to facilitate fastening the cover to the cushion.

Medical and/or robotic devices, systems and methods can provide an indicator associated with each manipulator assembly of a multi-arm telerobotic or telesurgical system. The exemplary indicator comprises a multi-color light emitting diode (LED) mounted to a manipulator moving an associated surgical instrument, allowing the indicator to display any of a wide variety of signals. The invention may provide an additional user interface to facilitate communications between the telesurgical system and/or members of a telesurgical team.

A cementitious material is provided that includes a phosphate based component and an alkali earth component. The alkali earth ion component has as a majority source a calcium aluminate calcium ion source of dodeca-calcium hepta-aluminate, or tricalcium aluminate. Magnesium oxide that has been fused and crushed to a size of less than 200 microns, alone or in combination with the calcium aluminate calcium ion source is also provided as the alkali earth ion component. When the phosphate based component and alkali earth ion components are combined in appropriate proportions, a rigid structure is obtained. A cementitious material formulation is also provided having an aqueous acidic phosphate solution as a part B and an alkali earth ion source as a part A that includes calcium aluminate, magnesium oxide or a combination thereof. Other additives include strength enhancing insoluble phosphate additive, an impurity metal reaction suppressant, tackifiers, anti-foaming agents, and the like.

A method of performing a surgical procedure on a patient is provided. The method typically comprises positioning a surgical work station of a robotically controlled surgical system and a patient on which a surgical procedure is to be performed in close proximity relative to each other, directing a field of view of an image capture device of the surgical work station at a surgical site on the patient, at which site the surgical procedure is to be performed, and introducing at least one robotically controlled surgical instrument on the surgical work station to the surgical site so that an end effector of the surgical instrument is within the field of view of the image capture device. The method typically further comprises displaying an image of the surgical site and the end effector on a display area of an image display at an operator control station of the surgical system. The image display is typically operatively connected to the image capture device so as to display, on the display area, the image of the surgical site and the end effector captured by the image capture device. The method can further include permitting an operator of the surgical system to manipulate a master control at the operator control station whilst viewing the image of the surgical site on the image display, the master control being operatively associated with the surgical instrument thereby to cause the end effector to move in response to manipulation of the master control so as to perform at least part of the surgical procedure on the patient at the surgical site. The method yet further typically comprises operatively linking the image display to a source of selectively accessible auxiliary information related to the surgical procedure to be performed, enabling the operator selectively to access the source of auxiliary information from the operator control station so as to forward the auxiliary information to the image display, causing the auxiliary information to be displayed across the display area of the image display in response to the operator selectively accessing the source of auxiliary information at the operator control station and enabling the operator selectively to move the auxiliary information when displayed on the image display relative to the image of the surgical site displayed on the image display. The master control is typically operatively linked with the source of auxiliary information, enabling the operator selectively to access the source of auxiliary information then including permitting the operator selectively to disassociate the master control from the surgical instrument and to use the master control to access the source of auxiliary information so as to enable the auxiliary information to be displayed on the display area of the image display.
摘要:
A refractory structural element is provided that is useful for lining the inner surface of a construct typically used as a kiln or other high temperature system. An element includes a stem portion associated with a flared end block portion whereby the flared end block portion is compatible with other structural elements to form a substantially continuous tiled surface when a plurality of refractory structural elements are laid adjacent to each other. The stem portion optionally has a plurality of protrusions decorated on its outer surface that may serve to adjust heat dissipation from the element.

摘要:
Bonded aggregate compositions such as concrete, concrete repair products, high temperature refractories, high temperature insulation and fire resistant insulation are made from an aqueous solution of phosphoric acid and a separate, storable dry mixture of suitable aggregate, monocalcium phosphate, and calcium in the form of calcium aluminate cement or calcium oxide. The proportion of wet to dry constituents is variable so as to select the working time and strength of the aggregate composition, typically on the order of ten to fifteen minutes. The mixture of the preferred dry constituents, and the binder to be mixed with the aggregate to yield the preferred dry mixture, are also disclosed. The binder system is particularly advantageous in that the same set of binder constituents can readily be employed with a variety of aggregates, reducing the cost of providing a variety of aggregate compositions due to the ready availability of the raw materials and obviating the need to stock different binders for different aggregate compositions. Cost is additionally reduced through the use of less purified, and therefore less expensive constituents.
