Abstract: A ring-like adjustment member having a plurality of adjustable elements is mounted in a tooth-encircling relationship with a prepared tooth having a finish line. Each element is adjustably movable so that its leading edges may be moved toward an attachment line defined by the neck of the tooth and its immediately adjacent gingival tissue below the visible gum line. The leading edges, after adjustment, define an impression line whose contour resembles the contour of the finish and/or attachment lines. Accurate custom-made impressions of the prepared tooth may be obtained. The adjustment member may also be mounted on the prepared tooth to assist in the formation of a temporary crown, and may further be mounted as a readily removable matrix on a tooth requiring filling.

Abstract: A detachable luggage-supporting, ground-engaging convertible accessory unit comprises a base member and at least one slide member which is guided for sliding movement on the base member. The base member is secured to a piece of luggage. A caster roller device is mounted on one slide member to form a caster roller assembly. A runner skid is connected to another slide member to form a skid-type runner assembly. A cantilever leaf spring on the base member snappingly engages each slide member for interconnecting the base member and the respective slide member with snap-type action. An access opening is formed on each slide member to expose the spring to permit a disassembly tool to remove the slide member from the base member, to thereby effect the rapid interchange of one caster roller assembly for another, or for the skid-type runner assembly. The slide member covers the spring except at the access opening so that the members are not readily detachable during luggage transport.

Abstract: A position measuring system comprising a transmitter (5, 19) mounted on one body and arranged to direct a flashing beam of radiation onto an area sensor (11) which is mounted on the other body and forms part of a receiver arranged to produce an output indicative of the position of impingement of the beam on the sensor from samples of the radiation impinging on the sensor when the beam is on and off, the receiver including a second sensor (31) responsive to the radiation beam whose output synchronizes the operation of the receiver to the flashing beam. The requirement for a physical connection between receiver and transmitter to synchronize the receiver with the flashing beam is thereby avoided.

Abstract: A chair shell of resilient material such as polypropylene comprises a back support 12 and a seat portion 14. The natural deformability of the back support 12 is modified by slits 22, 24 and holes 32, 34, 36 so that under pressure from the back of a sitter resting against the back support the support is resiliently deformed into a shape which, in vertical section, includes a convex curve positioned properly to support the sitter's spine in the lumbar region and which is horizontal in convex section. The deformability of seat 14 can be modified by slits 42, 44 and holes 42, 46, 48, 50, 54 to provide softer rear and front zones 44 and 52 to reduce the pressure on the ischial tuberosities and lower thighs of the sitter. The chair shell provides comfortable and orthopaedically desirable support while avoiding the need for thick upholstery. The undeformed state of the chair shell may be designed to allow the chairs to be easily stacked.
