Filed: 1991-07-26
Granted: 1995-01-10
Abstract: A replacement elevator call button unit which may be electrically connected to an Otis Elevator controller having first and second power supply lines and having an elevator call registering terminal.  The replacement unit includes an electronic switch (preferably a silicon con-trolled  rectifier)  which  is  electrically  connectible between the power supply lines.  A normally open push but-ton is electrically coupled to the switch in order to switch the first switch from an inoperative state in which current flow between the power lines is prevented, to an operative state in which such current flow is permitted. A voltage divider is provided for electrical connection across the elevator call registering terminal, in series with the switch means.  Cross firing between two or more corresponding replacement units is accomplished by a second electronic switch  (preferably a photo diode)  optically coupled to the first switch.  The second switch switches the first switch from the inoperative state to the operat-ive state upon application of a predetermined signal to the call registering terminal by the elevator controller.  The second switch is electrically connectible between the call registering terminal and the second power supply line.

Title: Attachment member for insulation panels
Inventor: ROTHENBUHLER WALTER
IPC: E04F13/04
Filed: 1991-12-20
Granted: 2002-02-26
Abstract: A member (1) secured in place by a fastening element (5) attaches insulation panels (2) to a structural component (A). The fastening element (5) is driven into the structural component (A) by a setting tool (8). To prevent damage to sector-shaped parts (6) extending radially inwardly in the entrance to a passageway (4b) through the attachment member (1), a diametrically increased section (4d) of the passageway extends axially inwardly from the entrance. The diametrically increased section (4d) has a diameter increased by twice the thickness of the sector-shaped parts (6) compared to the adjacent inward diameter of the passageway, and an axial length at least equal to the free length of one of the sector-shaped parts (6). When the muzzle end (8a) of the setting tool (8) is inserted into the passageway (4b), the sector-shaped parts (6) are bent inwardly within the diametrically increased section (6d) of the passage-way (4b) and, in combination with the passageway serve as a guide surface for the setting tool. The sector-shaped parts (6) rebound when the setting tool (8) is removed from the passage-way. When a coat of plaster (9) is applied over the insulation panels and the attachment members, the plaster penetrates behind the sector-shaped parts (6) and effects a back-gripping action.

Title: Combination lift piston/axial port unloader arrangement for a screw compressor
Inventor: LINNERT PETER J
IPC: F25B41/00
Filed: 1992-07-22
Granted: 1994-06-14
Abstract: Title COMBINATION LIFT PISTON/AXIAL  PORT UNLOADER ARRANGEMENT  FOR A SCREW COMPRESSOR                       Inventor PETER J. LINNERT                      Abstract An unloading arrangement for a rotary screw compressor includes discrete and different unloading apparatus associated with the male and female rotors respectively.  The unloading apparatus associated with the male rotor is an axial piston continuous unloader movably disposed in a bore which is remote from but in flow communication, through a series of ports, with the compressor's working chamber.  The unloading apparatus associated with the female rotor is a step unloader which, when opened, unloads the compressor in a single, relatively large capacity step.  The compressor is therefore capable of being unloaded both over a continuous operating range and in a discontinuous, stepwise fashion.  By duplexing compressors of this type, continuous capacity modulation of a multiple compressor system is made available over a large operating range without the employment of compressors unloaded by slide valve mechanisms.

Title: A method and an apparatus for producing a container
Inventor: NILSSON TORSTEN
IPC: B29L23/00
Filed: 1991-09-23
Granted: 2004-02-10
Abstract: The present invention relates to a method and an apparatus for orienting amorphous plastic material in that the material is caused to be displaced through a gap with a smallest gap width less than the material thickness of the plastic material. During such displacement, the material is oriented under the formation of a transition zone (18) between as yet unoriented (thicker) material (16b) and oriented (thinner) material (16a). The material is displaced at a speed entailing that crystallization energy released on the orientation reaches the defining surfaces (14, 17) of the plastic material at a point in time when the material has already assumed its reduced thickness. The apparatus includes a drawing ring (50) and a mandrel (60), between which the gap is formed. When the plastic material enters into the gap, the gap is of a width which substantially corresponds to the material thickness of the amorphous material. In the direction of displacement of the plastic material, the gap width is reduced so as to be less than the material thickness of the amorphous material, but exceed the material thickness of the oriented material.

Title: Electroluminescent silicon device
Inventor: CANHAM LEIGH TREVOR
IPC: H05B33/12
Filed: 1992-03-25
Granted: 2002-02-19
Abstract: An electroluminescent silicon device (10) includes a silicon structure (12) which comprises a bulk silicon layer (14) and a porous silicon layer (16). The porous layer (16) has merged pores (20) which define silicon quantum wires (18). The quantum wires (18) have a surface passivation layer (22). The porous layer (16) exhibits photoluminescence under ultra-violet irradiation. The porous layer (16) is pervaded by a conductive material such as an electrolyte (24) or a metal (48). The conductive material (24) assures that an electrically continuous current path extends through the porous layer (16); it does not degrade the quantum wire surface passivation (22) sufficiently to render the quantum wires (18) non-luminescent, and it injects minority carriers into the quantum wires. An electrode (26) contacts the conductive material (24) and the bulk silicon layer has an Ohmic contact (28). When biased the electrode (26) is the anode and the silicon structure (12) is the cathode. Electroluminescence is then observed in the visible region of the spectrum.

Title: Indoor climate controller system adjusting both dry-bulb temperature and wet-bulb or dew point temperature in the enclosure
Inventor: SHAH DIPAK J
IPC: F24F11/02
Filed: 1994-04-25
Granted: 2002-06-04
Abstract: A controller for a climate control system has a humidity (wet-bulb or dew point) temperature sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity temperature value is used in connection with the dry-bulb temperature to generate a single error signal which is a function of both the dry-bulb and the humidity temperature values. This permits control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the humidity temperature, the humidity temperature can be synthesized from the relative humidity and dry-bulb temperature within the enclosure.
