Title: Wrap-around carrier with flexible heel aperture
Inventor: SUTHERLAND ROBERT L
IPC: B65D71/22
Filed: 1994-06-20
Abstract: Means for holding the bottoms of petaloid shaped bottles (B) in place in a wrap-around carrier. Side panel apertures include flaps (70) connected to the side panel (34) by fold lines (64) which are inwardly curved at their upper portions. The lower portions of each pair of flaps extend toward each other so as to engage one or more support feet of the adjacent bottle and be forced out from the side panel (34) thereby. The curved portion of the fold lines biases the flaps against the support feet, regardless of which portion of the feet engage the flaps, to assist in holding the bottles in place within the carrier. Fold lines (76) extending from the flap edges to the flap fold lines and hook-shaped slits (80) at the upper ends of the flaps allow the side flaps to flex lengthwise.
Patent CA-2142481-A1 (CA)
Inventor: BAKER GERALD N
IPC: H02K19/10
Filed: 1995-02-14
Abstract: A switched reluctance motor (M) comprises a stator assembly (SA) including a stator (S) having a central bore (B) and a plurality of inwardly extending salient teeth (ST). A plurality of stator windings (W) are installed on the stator teeth. A rotor assembly (RA) includes a (R) rotor mounted on a rotor shaft (RS) and installed in the central bore for rotation with respect to the stator assembly. The rotor assembly has a pluralitry of outwardly extending salient teeth (RT) with gaps (G) extending lengthwise of the rotor assembly between adjacent rotor teeth. A noise reducer assembly (10) installed on the rotor assembly reduces the noise produced by the rotor when the motor is operating at normal speeds. The assembly includes a lug (14) made of an electrically non-conducting material inserted in each rotor gap and extending the lengthwise of the rotor assembly. Each lug is hollow with sidewalls (16A, 16B) and an inner endwall (16C) all of whose contours generally form mating contours with the respective sidewalls of the rotor poles and the contour of the rotor at the inner end of a gap. An outer endwall (16D) of a lug has a curved contour the curvature of which generally corresponds to the curvature of the outer face of the rotor poles. The lugs produce a surface between the outer faces of the adjacent rotor poles which generally conforms to the outer surface (F) of the rotor poles for the outer surface of the rotor assembly to begenerally uniform thereabout. This helps reduce motor noise. The assembly also includes a cap (20) fitting over each end of the rotor assembly. The lugs are attached to the cap so to install the lugs on the rotor assembly.

Title: Device for the injection moulding of plastic objects enclosing hollow spaces and process for operating it
Inventor: ECKARDT HELMUT
IPC: B29C45/17
Filed: 1993-09-25
Abstract: The proposal is for a device for injection moulding plastic items enclosing hollow spaces with which a further pressurised medium like air, gas or a fluid can be introduced through a hollow needle (5) at a point differing from the nozzle into a mould (1), the mould hollow or cavity (4) of which can be filled with molten pastic through a nozzle. There is a needle core (9) which can be moved axially to a limited extent in the hollow needle (5) and it is possible via this needle core (9) to vary the cross-section of or open and close the aperture (16) of the hollow needle (6) opening into the mould hollow or cavity (4). The needle core (9) bears a thickened head or plate (10) in front of the end of the aperture in the hollow needle, the outside diameter of which corresponds at least approximately to the outside diameter of the hollow needle, so that it forms, with the aperture end (6) of the hollow needle (5), a radially directed splitting valve. In relation to the hollow needle (5), the needle core (9) is axially supported by spring means (23). It is important here that these spring means (23) continuously engage with the needle core (9) in the closing direction of the aperture of the splicing valve (16) and that the needle core (9) can be moved against the spring means (23) in the opening direction by a remote-controlled driving device (17, 18).

Title: Sinker for a Circular Knitting Machine
Inventor: HUNG JUNG HAO
IPC: D04B15/06
Filed: 1995-05-26
Abstract: Disclosed is a sinker for a circular knitting machine being characterized by two symmetrical L-shaped recesses formed at two lateral sides of an upper half of a front top portion of the sinker, including a nose and a nose slot formed above the portion.  The L-shaped recesses are so formed that, when the sinker is moved into a corresponding channel on the needle cylinder in front of the sinker, the recesses are located slightly above the channel.  When the sinker reciprocates back and forth to together with the up and down latch needle form and knit piles, dust so produced settles on the L-shaped recesses and is removed therefrom without falling into and cumulating in the channel of the needle cylinder due to the movements of the sinker at high speed.  The cleaning of needle cylinder and sinkers can be minimized and the quality of knitted fabrics can be enhanced with the arrangement of such L-shaped recesses on two sides of the sinker.

Patent CA-2163480-A1 (CA)
Inventor: TWARDOWSKI ZBIGNIEW
IPC: B01D61/02
Filed: 1995-11-22
Abstract: A nanofiltration process using a conventional nanofiltration membrane module under a positive applied pressure is used to selectively change the concentration of one solute, such as sodium chloride or sodium chlorate providing monovalent ions, from another solute such as sodium sulfate or sodium dichromate providing multivalent ions in high salt aqueous concentrations. The process is particularly useful in favourably lowering the concentration of silica and dichromate ions in chloral kali and chlorate brine containing solutions and favourably raising the sodium sulphate level relative to sodium chloride in chloraldhali liquor. The relatively high salt concentration, surprisingly, effects little or no monovalent, particularly, Cl rejection.
