Patent CA-1289374-C (CA)
Title: Coffee or tea machine
Inventor: HAUSLEIN REINHARD
IPC: A47J31/057
Filed: 1987-10-05
Granted: 1991-09-24
Abstract: Abstract This invention relates to a brewing machine suitable for brewing coffee or tea.  In prior art domestic machines, delivery of water to the filter is slow and poorly distributed.  In this invention, water held in a freshwater container is heated by means of a continuous flow heater and is delivered, through a riser pipe and an overflow device, to a filter-vessel located above a liquid receiving pot.  The overflow device comprises an inter-mediate container, into which the riser pipe opens, and having a siphon and a vent pipe which extends beyond a bend in the siphon.  The intermediate container is other-wise completely sealed.  If the intermediate container is filled as high as the bend in the siphon, the siphon is activated and empties the intermediate container completely.  This ensures that the brewing water flows more rapidly into the filter vessel.

Title: Sterol regulatory elements
Inventor: BROWN MICHAEL S
IPC: C12Q1/6897
Filed: 1988-03-30
Granted: 1992-05-12
Abstract: STEROL REGULATORY ELEMENTS                          ABSTRACT      Disclosed are discreet functionally translocatable DNA segments, termed Sterol Regulatory Elements (SRE's), which are fused to heterologous structural genes to provide sterol regulatory capability to the thus formed hybrid gene.  The hybrid genes respond to sterols by decreasing the production of messenger RNA.  The SRE segments contain as their primary functional nucleotide sequence, a 16 bp sequence referred to as direct repeat 2, isolated from the 5' regions of the human LDL receptor gene.  DNA segments which include this 16 nucleotide long sequence similarly confer sterol regulatory capability to previously known promoters such as the HSV TK promoter. Also disclosed are discreet sequences which confer positive transcription promotion to heterologous structural genes and promoters without conferring sterol responsivity.  Methods are disclosed for employing these genetic control elements in a myriad of embodiments which provide for a fine-tune control of heterologous genes. Methods are also disclosed for employing the SRE in a screening assay for drugs capable of stimulating the cell to synthesize LDL receptors.

Title: Raster distortion corrected deflection circuit
Inventor: HAFERL PETER E
IPC: H04N3/233
Filed: 1989-03-09
Granted: 1992-04-28
Abstract: RCA 85,011 ABSTRACT A deflection switch of a horizontal deflection circuit is coupled to a retrace resonant circuit that includes a horizontal deflection winding and a first retrace capacitance.  A flyback transformer primary winding is coupled at a junction terminal of the deflection switch and the retrace resonant circuit.  A second winding of the transformer is coupled to an ultor voltage power supply. To provide side pincushion correction, a second switch, having a conduction time that is phase modulated during horizontal retrace at a vertical rate in parabolic manner, is coupled between ground and a terminal of the retrace resonant circuit remote from the flyback transformer primary winding.  The second switch is conductive during the entire trace interval and is turned-off at a controllable instant during the first half of the retrace interval. When the second switch is nonconductive, a second retrace capacitance is interposed between the flyback transformer primary winding and the retrace resonant circuit to prevent load variation in the second winding of the flyback transformer from causing raster distortion.
