IPC: B01F13/10
Filed: 1994-05-10
Abstract: APPARATUS FOR DISPENSING HYDRATABLE MATERIAL             ABSTRACT OF THE DISCLOSURE        An   apparatus  for  dispensing  a  hydratable material includes   a   source  of  the  hydratable material  to  be dispensed, including a container and a  metering  unit.  A continuous-flow first mixer has a  truncated  conical  mixing  chamber  with  an open upper  end  and an open lower end of smaller diameter than  the  upper  end.   The upper end is disposed to receive  the  flow  from  the  metering  unit and the lower  end  delivers  a  flow  of  a  mixture  of the hydratable  material and water.  A plurality of water inlet  openings  at  an upper end of an inner surface of   the   conical  mixing  chamber  introduce  water tangentially  along  the  inner  circumference of the cone  to  create  a vortex effect within the cone.  A continuous-flow  second  mixer is positioned directly adjacent  to  and  below the first mixer and receives the  flow  of  mixture  from  the  first  mixer.  The second  mixer includes at least one outlet opening of a  size  less  than  a  preselected size, an impeller disposed  to  mix  the mixture of hydratable material and  water  with  high  energy  and force the mixture toward  the  outlet  opening,  and a motor that turns the  impeller  to  have a tip speed of at least about 25 feet per second.

Patent CA-2127975-A1 (CA)
Inventor: MASUDA ISAMU
IPC: A47C27/15
Filed: 1990-03-28
Abstract: The present inventions is directed to a bed mattress, in which a mattress body  (1)  is  formed with a core portion consisting of a hard molded foam having a sufficient thick-ness or hollow synthetic resin moldings having a rigidity, and elastic  surface layers  (6),   (7)  including protecting plates (4),   (5) overlayed on both sides of the core portion (3) sandwiched therebetween.  At least one of the surface layers (6),   (7) is formed by overlapping a first cushion layer  (10)  consisting of  a soft cushion material,   and a second cushion layer (11) consisting or a semihard cushion material having a depression-and-protrusion surface (13) on its surface on the protecting plate 4.      In a conventional bed mattress,   since a plurality of coil springs fixed to a metal frame is incorporated,  a gross weight becomes heavier and handling is inconvenient.  In this invention,  however, since the metal member is not used and a hard molded foam and hollow synthetic resin moldings having a rigidity are used as a core portion (3),  it is light and there is no problem of rusting and breaking. Besides,  since the  depression-and-protrusion  surface  (13)  of  the  second cushion layer (11) on the surface layer supports the body in point contact,  a good permeability and the finger-pressure operation by the protrusions (14) are obtained for improving health.

Title: Plug-in socket joint secured against sliding movement
Inventor: BERGMANN KARL-HEINZ
IPC: F16L37/092
Filed: 1994-07-27
Abstract: The plug-in socket joint secured against sliding movement is intended for socket pipes manufactured by centrifugal casting, in which the spigot end of one pipe may be inserted with radial play into the socket end of the other pipe. In this joint, a sealing ring and a clamping ring structurally separate therefrom are arranged, said clamping ring being composed of a plurality of clamping segments spaced from one another in peripheral direction. The latter have a spherical outer shell surface, are connected to each other in peripheral direction by means of a moulded-on intermediate layer of rubber or similar and each have a toothing on their inner surface. A holding part, which may be fixed in the area of the socket face end and supporting same, is formed on the clamping ring and comprises a connecting section extending to the clamping ring and tapering approximately conically, and may be expanded together with the clamping ring in dependence on the outer dimensions of the spigot end to be inserted and may thus be extended in axial direction. To prevent the toothing of the clamping segments from corroding as a result of penetrating moisture and oxygen, the connecting section is provided in its area extending from the clamping ring with the clamping segments to the holding part with at least one ring-shaped sealing edge protruding radially inwards and elastically enclosing the spigot end of the inserted pipe.

Title: Induction motor speed control having improved sensing of motor operative conditions
Inventor: WILKERSON ALAN W
IPC: H02P1/42
Filed: 1994-05-23
Abstract: 2142624 9428617 PCTABS00034 An apparatus and method control the speed of an AC induction motor by varying the frequency and current to the motor from an inverter power supply. A Counter EMF regulator receives a reference signal corresponding to the desired speed, and a signal proportional to CEMF for feedback. The output of the CEMF regulator is provided to the power supply to control the current to the motor. The CEMF feedback signal is also utilized to vary the output frequency of the power supply in accordance with the magnitude of the CEMF. This maintains the magnetizing component of stator winding current at a constant value for all operating frequencies of the motor. A signal corresponding to the load current component of the stator winding adds to the speed reference signal to the CEMF  regulator to increase CEMF and frequency with increasing load, thereby to compensate for increased slip and maintain constant speed.  The phase displacement between CEMF and stator winding current is determined. If the phase displacement is less than 90·, the motor is in the motoring condition and the frequency of the power supply is determined solely by the CEMF. If the phase displacement is greater than 90·, the motor is regenerating, and the frequency of the power supply is increased to prevent regeneration, and to avoid the need for the power supply to absorb regenerative energy.

Title: Method and kits for detection of bacteria
Inventor: SANDERS MICHAEL F
IPC: C12Q1/04
Filed: 1993-09-22
Abstract: A method for detection, identification and/or quantification of target organisms of specific bacterial genus, species or serotype, based upon the occurrence of release of cell contents, particularly nucleotides e.g. ATP, on lysis of bacterial cell walls on incubation with bacteriophages (phages) specific for them. When new phage particles are released at the end of the phage replication cycle nucleotide levels are measured and compared with controls. The method provides for the detection of specific bacteria in which insertion of the lux gene into the phage genome is not required yet it is faster and more sensitive than known non-modified phage utilising techniques. The method is only limited by the availability of phage types suitable for selective attack of the target bacteria to be detected and can detect a single Salmonella in a sample of milk in under 12 hours.

This plate has a pivot point opposite to the first steering plate, giving it the capability of steering in the reverse direction. A locking pin, in the form of a double ended cylinder is utilized to switch steering directions and utilize the same actuator.
