Patent NL-8503359-A (NL)
IPC: F16H1/12
Filed: 1985-12-05
Abstract: Face-gear transmissions in which the teeth-tip-height T can be increased considerably in the region where the face-gear teeth have increased pressure angles a, resulting in considerably increased loading capacity and meshing quotient, all based on meshing cooperation with standard cylindrical gears with either straight (spur) or helical teeth. The angle between the transmission shafts 3, may be 90°, less or over, the shafts may intersect or cross. In case involute toothing is chosen for the cylindrical gear wheel, all well-known advantages remain valid, thus alignment of the transmission is considerably less critical than with bevelled transmissions, axial- pinion loads are less or absent, loading capacity is comparable or better and transmission ratios surpassing approximately 1:5 become the more attractive. In many cases less transmission steps will be possible, reducing size and cost. Simple replacement becomes possible, without any alignment problems. Face gear transmission now may be used for primary, high load, long-life industrial applications.

Patent NL-8800072-A (NL)
IPC: C07C1/04
Filed: 1988-01-13
Abstract: A process is described for converting carbon oxylsulfide and/or carbon disulfide, possibly in combination with hydrogen cyanide, O2 and/or SO2 in a reducing CO containing gas stream by the catalytic hydrolysis of COS and CS2, followed by the removal of H2S, present and formed, from the gas stream. According to the invention, the process is characterized by   a) a first stage (12) comprising converting a portion of the CO present with water in the presence of a catalyst with simultaneous or subsequent hydrogenation of any O2 and/or SO2 that may be present; b) a second stage (14) comprising catalytically hydrolysing COS and/or CS2, possibly in combination with HCN in the gas stream, with water; and c) a third stage (20) comprising removing substantially all sulfur components from the gas stream; the catalytic conversion of CO in stage a) being effected so that the heat thereby produced is substantially sufficient to raise the temperature of the gas stream to the value required for the hydrogenation and for the second stage.

Title: Process for the selective hydrogenation of triglyceride oils with a metallic catalyst in the presence of a diamine
IPC: C11C3/12
Filed: 1980-06-19
Abstract: Unsaturated fatty acid derivatives which, besides fatty acids with two double bonds, contain fatty acids with more than two double bonds, are hydrogenated in the presence of a palladium, platinum or rhodium catalyst which has been treated with ethylenediamine or a homologue and/or a derivative thereof and at a temperature of -20 DEG to 100 DEG  C. The hydrogenation progresses very selectively while very little isomerization to trans-fatty acids occurs. For example, in the hydrogenation of soya bean oil to a linolenic acid content of 2%, the linoleic acid content only decreases to 45-52%. Under identical conditions an untreated catalyst leads to a linoleic acid content of about 35%.

Title: Vertical deflection circuit
Inventor: SUTHERLAND HUGH FERRAR II
IPC: H04N9/29
Filed: 1987-04-08
Abstract: A vertical deflection amplifier (20) of a video display apparatus includes first (Q1) and second (Q2) transistor amplifier output stages arranged in a totem-pole, push-pull configuration. A vertical-deflection winding (LV) is coupled to the output stages at a deflection amplifier output terminal (22). An S-capacitor (C1) is coupled to the deflection winding (LV) at a second terminal (21) remote from the output terminal (22). A source (23) of deflection rate signals is coupled to the deflection amplifier (20) for generating a deflection current (iv) in the deflection winding (LV). A base current generating circuit (40) is coupled to one (Q1) of the transistor amplifier output stages for providing base current (i1) thereto. The S-capacitor voltage (V1) is applied to the base current generating circuit (40) for enabling conduction of base current (i1) in the one amplifier output stage (Q1). When the video display apparatus is first turned on, the initially discharged S-capacitor (C1) is slowly charged from a DC voltage supply (+30V) to delay generation of vertical def lection past completion of picture tube degaussing. A DC power supply (16) upon energization in response to a switch (15) produces a DC level (+DC2) sufficient for operating the deflection amplifier prior to the conclusion of degaussing.

Title: Method and device for manufacturing a mineral wool web
Inventor: LAUREN HENNING
IPC: D01G25/00
Filed: 1987-04-24
Abstract: PCT No. PCT/FI87/00054 Sec. 371 Date Oct. 20, 1988 Sec. 102(e) Date Oct. 20, 1988 PCT Filed Apr. 24, 1987 PCT Pub. No. WO87/06631 PCT Pub. Date Nov. 5, 1987.The invention relates to a method and a device for producing a mineral wool web from a thin primary web formed on a movable collecting surface (6). According to prior known methods, the primary web is folded on a receiving conveyor (18) in an overlapping configuration so that the desired thickness of web is achieved. It is also known to combine two or several primary webs and to form the final mineral wool web by folding. The problem when producing mineral wool webs is the high rate of production of the primary webs and consequently, the high requirements on the devices in the further process and a great loss of material because of uneven edges which have to be cut down. According to the invention, the primary web is split into separate sheets before the deposit on the receiving conveyor (18), and the sheets are deposited by an oscillating distributing conveyor (16) in an overlapping configuration on the receiving conveyor, or, in case sheets are being produced, stacked on top of each other. The method offers several possibilities of reducing the feeding rate of the sheets and thus facilitating the deposit on the receiving conveyor. The flow of split sheets may for instance be separated (11, 12) into two or several flows to an intermediate conveyor each (14, 15) and the sheets may be stacked before the deposit. The cutting of the primary web may be performed on the collecting surface (6) or optionally after this on an intermediate conveyor.

Abstract: A mobile monitoring device for detecting a fire, gas leak, intruder, of other abnormal condition in a house or office, and for alerting a central monitor, fire station, police station, or an occupant who is away from the house or office. The mobile monitoring device comprises a self-propelled movable robot having sensors located thereon; a monitor for receiving signals from the robot and alerting an authorized user accordingly; an automatic communication control unit including a telephone transmitting unit for automatically calling an appropriate party in response to a signal from the robot and for transmitting commands to the robot from an authorized calling party; and an RF remote controller for remotely controlling the robot. The robot is specifically capable of navigating throughout a house or office while using its sensors to detect abnormal conditions. In the event that an abnormal condition is detected, the robot initiates communications with the monitoring means and the automatic communication control unit to thereby alert an appropriate party of the existing abnormal condition. Commands can be provided to the robot either directly through a keyboard on the robot itself, or remotely by way of the RF remote control means or the automatic communication control means. <IMAGE>
