Patent CA-2003802-A1 (CA)
IPC: F24H3/08
Filed: 1989-11-24
Abstract: RHEE     ABSTRACT         An induced draft, fuel-fired upflow furnace is provided with a compact,  high efficiency heat exchanger having horizon-tally spaced apart inlet and outlet manifold structures which are innerconnected by a horizontally spaced series of vertically ser-pentined, relatively small diameter flow transfer tubes.  Larger diameter inlet flow tubes are positioned beneath the balance of the heat exchanger, extend parallel to the transfer tubes, and have upturned discharge ends connected to the underside of the inlet manifold.   The heat exchanger is configured so that its total vertically facing peripheral surface area is considerably Larger  than  its total  horizontally  facing  peripheral  surface area,  thereby  significantly  reducing  undesirable  outward heat loss through the vertically extending furnace housing side walls upon burner shut off and increasing the overall efficiency rating of the furnace.   The small diameter, serpentined transfer tubes create a significant flow restriction within the heat exchanger to thereby increase heat transfer to the continuing supply air flow through the furnace after burner shut off.  The reduced mass of the heat exchanger, compared to conventional clamshell heat exchangers, also desirably lessens its cold startup "dwell time" to inhibit internal heat exchanger corrosion.   A pilot bypass system is provided to inhibit internal heat exchanger corrosion potentially caused by the continuously generated combustion pro-ducts of a standing pilot flame within the furnace housing by venting  such  combustion  products  directly  through the  draft inducer fan outlet section and into the exhaust flue,  thereby bypassing the heat exchanger, during idle periods of the furnace.

Patent CA-2010435-A1 (CA)
Inventor: BRUKE RICHARD
IPC: B65G33/26
Filed: 1990-02-20
Abstract: An apparatus for displacing material includes a transport thread composed of a central thread spiral and an outer thread. The outer thread spiral is fixed to one of the radially directed defining surfaces of the central thread spiral. The central thread spiral is dimensioned so as, without permanent deformation, to absorb at least the major portion of the mechanical forces occurring in the axial and radial direction of the transport thread. The outer thread spiral has an outer surface which faces away from the geometric centre axis of the transport thread and is of shorter extent in the axial direction of the transport thread and is located more distally from the center axis than the outer surface of the central thread spiral. By regulating the extent in the axial direction of the transport thread of the surface of the outer thread spiral turned to face the substrate, the abutment pressure of the transport thread will be adapted to the substrate in relation to the properties of the material being displaced.

Title: Breast pump
Inventor: RIEDWEG ROBERT
IPC: F04B9/14
Filed: 1990-02-26
Abstract: The breast pump comprises a milk reservoir and a flanged closure member for connection with the reservoir; the closure member comprises a suction bell and a suction pump suitable for single-handed manual operation and includes (a) a cylinder integrally connected with the closure member; (b) a piston means for reciprocating motion within the cylinder between a first or lower position and a second or upper position, and (c) a spring-loaded actuator for interaction with the piston means. According to the invention, the actuator is a yoke structure formed of an elongated flat spring member that tends to revert into a first or rest position and is reversibly deformable into a second or substantially bent position; the spring member has two ends and is connected with the piston near the spring's middle; the yoke further comprises a pair of elongated lateral legs which are functionally rigid, i.e. substantially less elastic than the flat spring; each lateral leg has a lower end and an upper end; each lower end is connected with an open ended ring slideably mounted on the closure member; the upper ends of the legs are connected with the ends of the spring member; the yoke is dimensioned for single-handed manual compression of the lateral legs which, in turn, will cause bending of the flat spring member and so displace the piston upwards within the cylinder and cause suction within the suction bell; when the lateral legs are released the spring reverts into its rest position and a subsequent suction cycle can be initiated by again pressing the lateral legs against each other.

Title: Sealing member for a filter press
Inventor: HAAKANA MATTI
IPC: B30B9/24
Filed: 1990-08-30
Abstract: ABSTRACT OF THE DISCLOSURE    The  present  invention  relates  to  a  sealing  member preferably for sealing of the sides of the pressing zone of filter  presses  used  in  the  pulp  and  paper  industry. Previously known sealing members have been complicated. Most commonly they have been composed of sheet-formed rubber and supporting metal rods attached to each other with bolts. The users  have  not,  however,  been  satisfied  with  such arrangements because the bolt attachment has not facilitated the  structure of  the  sealing member remaining unchanged along the whole length of the press, but the sealing member has had to be left unsupported at the narrow end of the pressing zone, whereby it has often failed and let pulp be discharged to the press side.  Furthermore,  earlier seals have worn down very quickly. The sealing member according to the present invention solves the problems mentioned above because the sealing members (36, 38), made of practically permanent  material  which  is  ideal  as  to  its  friction properties relative to the wire surfaces, are constructed to form a single sealing member (30) together with the support members (32, 34), which sealing member (30) allows bending thereof conforming to the movements of the press wires, but prevents the tendency of the sealing member to bend, which tendency is caused by the pressure of pulp.
