Inventor: DROUET MICHEL G
IPC: C22B21/00
Filed: 1990-11-23
Abstract: A process is disclosed, for treating dross containing a metal such as aluminum, in order to recover this metal, In this process, the dross to be treated is introduced into a rotary or oscillating furnace, in which it is heated to a temperature above the melting point of the metal to be recovered while the furnace is rotated or oscillated to cause the metal to be recovered to separate from the dross. After the separation is completed, the metal to be recovered is removed from the furnace prior to removing the balance of the dross. In this process, the furnace that is used is a radiating arc furnace having two opposite electrodes which are preferably made of graphite, between which an electrical arc is generated and maintained in order to provide the desired heating.

Title: Method for polymerizing vinyl chloride while inhibiting adhesion to the polymerization reactor
Inventor: MASUKO SEIICHI
IPC: C08F14/00
Filed: 1990-12-18
Abstract: A method for polymerizing vinyl chloride comprises polymerizing vinyl chloride in an aqueous medium or bulk-polymerizing vinyl chloride, wherein the inner wall of a polymerizer and parts of devices which come in contact with the monomer during the polymerization are coated, prior to the polymerization, with a reaction product having a molecular weight ranging from 500 to 100,000, obtained by condensing a polyhydric phenol and sulfur dichloride in the presence of a Lewis acid as a catalyst. The amount of the polymer adhered to the polymerizer during polymerization of vinyl chloride is substantially lowered and the adhered polymer can be easily washed away through simple water washing according to the foregoing method. Moreover, the method does not adversely affect the reaction time and the quality of the resulting product at all.

Title: Call alerting device for telecommunications terminals
Inventor: BUNKENBURG MICHAEL
IPC: G08B6/00
Filed: 1991-07-19
Abstract: CALL ALTERING DEVICE FOR TELECOMMUNICATIONS TERMINALS    Abstract of the Disclosure A vibrating signalling device is used in conjunction with a telecommunications terminal for alerting a user to receipt of an electrical call signal by the telecommunications terminal.   A movable weight such as an armature is coupled to a receiver for the electrical call signal, and a pulsating force is generated by oscillating the movable weight electromechanically upon receipt of the electrical call signal, alerting the user to the electrical call signal apart from audible and visible signalling.  The signalling device can be an automatically functioning component included in a portable terminal device which also can provide an optical signal and/or an acoustic signal, and a switch or connector coupling disables the optical and/or acoustic signal when the terminal communicates with a separate signalling device over a wireless signalling path. Where the signalling device is wired to the terminal, a connector coupling can disable audible/visible signalling when the vibrating device is plugged in. The vibration signal generated is preferably at a sub-audible frequency and can correspond to the rhythm of the call signal. The device alerts the user to the call in a manner which is not perceptible to other persons nearby.

Filed: 1991-10-03
Abstract: A gas lighter with a safety device has a lock member which is able to linearly move between a locking position where it prevents depression of an ignition lever and a releasing position where it allows depression of the ignition lever and is urged to the locking position.  A holding member hold the lock member in the releasing position in response to movement of the lock member to the releasing position, and a releasing member releases the lock member from the holding member in response to depression of the ignition lever, thereby permitting the lock member to move away from the releasing position.  A temporary holding member temporarily holds the lock member in the releasing position or the vicinity thereof until the ignition lever returns to the original position.

Title: Humidity-sensing element
Inventor: KUROSHIMA HIROSHI
IPC: G01N27/12
Filed: 1990-02-26
Abstract: ABSTRACT A calcined or sintered material made from a ferroelectric metal oxide having a basic composition which is given by (Pb1-xLax)(ZryTi1-y)1-x/4O3 o<x?0.25, 0<y<1 is employed in ground form as a substrate material for a humidity-sensing element.  More specifically, the substrate material is molded into a sheet with a size of 6 x 6 mm and a thickness of 0.5 mm and then sintered in the atmosphere for a several hours at 800 to 1100°C to form a substrate. The resulting substrate is dipped for several seconds in an aqueous solution of 0.05 mol/R or more of an alkali metal phosphate.  After drying, the substrate is heat-treated in the atmosphere for several hours at 600°C to 900°C, thereby covering the entire surface of the porous substrate with an alkali metal phosphate.  As shown in Fig. 1, gold opposing electrodes 2 are formed on both surfaces, respectively, of a humidity-sensing member 1 by vacuum deposition, and a lead wire 3 is attached to each electrode by use of an electrically conductive resin adhesive to form a humidity-sensing element with a sandwich structure.  Further, the resulting element is allowed to stand for several days under high temperature and humidity conditions (60 to 90°C, 80 to 95%RH).  The humidity-sensing element exhibits an impedance of 1 M.OMEGA. when the relative humidity is 0% at 30°C and an impedance of 3 K.OMEGA. when the relative humidity is 90% at 30°C. Thus, the impedance changes in a range where a general measuring circuit can be readily combined with the humidity-sensing element.  In addition, the humidity-sensing element has substantially no change with time and a small temperature coefficient.

Title: Apparatus for the preparation of hot drinks
Inventor: WEBER RENE
IPC: A47J31/46
Filed: 1991-10-28
Abstract: Apparatuses for the preparation of different hot drinks, such as in particular espresso machines, conventionally have a multiway valve (2), which is used for supplying hot water or superheated steam produced in a water heater to different means, such as coffee filters, frothing nozzle and/or collecting vessels. As a result of high temperatures and pressures the multiway valve is exposed to considerable stresses, which in the long term cannot be withstood by known valves or only when a complicated and costly construction is adopted. In the novel apparatus the multiway valve is provided with a perforated disk (8) and a rotary control dial (9). Rods (14) for closing the distributing passages (5) are passed through the holes in the perforated disk. The distributing passages are provided in a distributing block (1) to which the multiway valve is flanged. The posi-tion of the rods is determined by the rotary position of the control dial provided with a guide link for the rods.
