Abstract: LOW-NOISE PUMP ASSEMBLY ABSTRACT OF THE DISCLOSURE The  low-noise  pump  assembly  (10)  comprises  a unitized assembly wherein a drive shaft (17) of the motor (16)  is mated directly with an eccentric coupling (23). The eccentric coupling (23) has a through bore (21) which receives at one end the drive shaft (17) and at the other end a center post  (30)  of the  pump  housing.   Disposed between the center post (303 and eccentric coupling (23) is a radially inner bearing mechanism (60),  and disposed between the exterior of the eccentric coupling (23)  and an opening (52) of a ring member (50) is a radially outer bearing mechanism (70).  The ring member (50) engages at least one reciprocating piston assembly  (45).   Rotation of the drive shaft (17) causes rotation of the eccentric coupling (23) to effect reciprocating motion of the pump piston (48).

Abstract: Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. The adhesive layer is smoke-permeable and is preferably composed of a material system which sets without a chemical reaction. The film web is produced from viscose, and it is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.

Abstract: Ceramic bodies are bonded by providing a first body formed of polycrystalline material and interconnected residual metal formed by the oxidn. reaction of molten metal and a vapour phase oxidant and grown as molten metal is transported through and then oxidised on the surface of its own oxidn. reaction prod.; holding a second ceramic body against a surface of the first; and heating so that the residual metal content of the first body is transported to the interface where an oxidn. reaction prod. continues to grown as above and forms a bond. - Specifically the metal is Al, oxidant is air and oxidn. reaction prod. is Al2O3. The first body may be formed by infiltrating a filler with oxidn. reaction prod. A barrier material, pref. Ca sulphate, silicate or phosphate or Portland cement, is used to embed and surround all surfaces of the first body except the contacting surface. A body of metal may be placed in contact with another surface of the first body embedded in the barrier material, so that the metal melts and is transported to the bonding interface during the heating step. The second body may have the same ceramic compsn. as the first; it may be made by a different method; or may be of a different compsn. but made by the same method. Pref. the reaction prod. is an oxide, nitride or carbide and the metal is Ti, Si, Zr, Hf or Sn.

Granted: 2002-06-18
Abstract: Measurement of lengths for determining the out-side diameter, wall thickness or inside diameter of tubes, specifically tubes of zircaloy alloy for use as cladding for nuclear fuel. The tubes must be maintained to close tolerances. The measurement is carried out with a laser micrometer which generates a planar laser beam. A mandrel of tungsten carbide having a coaxial projection is posi-tioned so that its transverse dimension intersects the beam and is parallel to the plane of the beam. A first length is measured between the end of the beam and the nearest point on the projection. A tube is mounted on the projec-tion with its longitudinal axis parallel to the longitudinal axis of the mandrel and its inner surface engaging this nearest point. A second length is measured from the end of the beam and the nearest point on the tube. The outside diameter is measured as a third length on the shadow of the tube produced by the laser between the shadow of the near-est point and the shadow of the most remote point from the end of the laser beam. The wall thickness is equal to the first length less the second length. The inside diameter 1s the outside diameter less twice the wall thickness. The width of the projection is only slightly greater than the width of the laser beam so that the tube is positioned, as nearly as practicable, on a knife edge. Each measurement of a length is the means of a plurality (typically eight) of measurements taken at eight, angularly and longitudinally, randomly displaced positions of a tube.      Evaluation based on misleading deviations from the control limits, such as a burr or a speck of dust on a tube, are ruled out. An advantage of this invention is that the measurement is carried out with only one instrument.      Prior-art practice requires the use of two instruments: one to measure the OD and the other the ID.

Title: Apparatus for trimming back fat off a pork loin
Inventor: LEBLANC GEORGES-EMILE
IPC: A22C17/00
Filed: 1990-03-16
Granted: 1993-12-14
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for trimming back fat off a pork loin comprises (a) a flat and arcuate cutting blade,  (b)  a conveyor formed  of an endless belt arcuate in cross section and having a smooth top surface, and (c) a pair of endless chains provided with teeth.  In operation, the loin is conveyed toward the blade between the endless chains and the top surface of the conveyor.  During its transport toward the blade the pork loin is pressed between the two chains and the conveyor with the teeth of the chains penetrating the meat.  The conveyor and the chains are driven at different linear speeds to produce in the pressed loin a compression and tension distribution which facilitates passage of the meat through the cutting blade and improves trimming of the back fat. As the top surface of the conveyor is smooth,  it allows the conveyed loin to slide laterally toward the center of the conveyor.  The loin is thereby centered before it reaches the blade.
