Abstract: ABSTRACT            A direct ventilation gas fireplace having co-linear air intake pipe and gas outlet pipe. The pipes are separated from each other so that the fluid flowing in one pipe does not come in contact with the other pipe. The gas outlet pipe may comprise a safety release valve that allows any excess pressure, in case of explosion, to exit through a lateral spring-actuated door into an enclosure closed around the combustion chamber. This safety release valve allows to build fireplaces having pipes longer than the usual length allowed for respecting specific safety tests in case of gas explosion.

Title: Coffee or tea machine
Inventor: SALOMON THOMAS
IPC: A47J31/44
Filed: 1992-02-14
Abstract: ABSTRACT          A coffee or tea machine has a base area into whose base shell (1) a continuous flow heater (10) can be inserted with a connector socket (7) as vertical oriented fixed point. The latter is held by an electrical circuit board (21) which is to be installed vertically, combining its electrical system with the circuit board (21). The circuit board (21) snaps into the base shell (1). Finally, a bottom (35) is snapped into the base shell (19), also with a vertical connecting movement, blocking at the same time the snapping together of the circuit board (21) and the base shell (1). The entire electrical system of the machine is housed in the base. If necessary, the base shell (1) and the bottom (35) can be made of fireproof plastic. However, the continuous flow heater connection could be sealed off by means of a sealing element which is generally regarded as physiologically safe.

Title: Use of organic acids in low residue solder pastes
Inventor: DAVIS JAMES L
IPC: B23K35/22
Filed: 1991-04-15
Abstract: Fluxing compositions are described containing as fluxing agents compounds of formula (I), where R is an electron withdrawing group. Im one embodiment, R is selected from the group consisting of fluorine, chlorine, bromine, iodine, sulfur, hydroxyl, nitrile, and benzyl. The compound cleans oxides from the printed circuit boards (PCBs) under assembly and then volatilize with little or no need for a cleaning step, or cleaning only with water of formic acid. Very little or no undesired residue remains, such acid fluxing agents can be used mixed with typical solder formulations, such as lead/tin solder pastes, or applied topically to solder, such as solder balls; both techniques permit the assembly of PCBs more easily with high quality bonds, and with little or no residue.  Malic acid is a preferred organic acid fluxing agent.

Abstract: PHN 13.701                10                 08.07.1991 ABSTRACT: "Prerecorded cassette for a system for magnetically recording/reproducing signals"     A prerecorded cassette (1) belongs to a system for magnetically recording/reproducing signals on/from magnetic tape in accordance with a standard, which system comprises apparatuses and cassettes compatible therewith, which cassettes comprise two parallel main walls and interconnecting transverse walls and occur with prerecorded tape (prerecorded cassettes 1) and with blank tape (blank cassettes 3), which standard specifies a tape length marking which can be detected by an apparatus and which marks the length of the magnetic tape in a cassette by a pattern of openings (33-37) in a marking zone (39) of a main wall (19) of a cassette (3), which tape length marking comprises a plurality of submarkings (33-37) in a binary multi-bit code, the value of each bit being defined by the presence/absence of an opening. With the prerecorded cassettes (1) a tape length marking is dispensed with completely and information about the playing time and information about the position on the tape are recorded on the tape as time code. Preferably, the system specification for the erase protection is such that, to indicate the impossibility of home recording, the prerecorded cassette does not have an erase protection opening at all. As a consequence, the prerecorded cassette (1) is not suitable, and can hardly be made suitable, for home recording. If the cassette is provided with a permanent label (55) the relationship betweenthe recording and the information on the label will be maintained for the entirelife of the cassette.

IPC: A24D1/00
Filed: 1992-10-29
Abstract: A novel cigarette system is described which has a greater number of puffs than a conventional cigarette of same dimensions and length of tobacco rod, namely at least about 14 puffs.  The cigarettes are intended to be partially smoked, extinguished, stored and then resmoked. A filter is attached to the tobacco rod of the cigarette constructed to provide a per-puff delivery profile of tar,  nicotine  and  flavour  to  the  smoker  which  is approximately  the  same  for  both  smokings  of  the cigarette.  The greater-than-normal number of puffs may be achieved by employing a slower burning tobacco blend, greater tobacco density and/or   burn rate retardant paper.  An extinguishing and storage device is provided to extinguish the cigarette after the initial smoking of the cigarette and to store the extinguished cigarette between smokings.

Title: Method of determining drillstring bottom hole assembly vibrations
Inventor: PASLAY PAUL R
IPC: E21B47/00
Filed: 1992-11-30
Abstract: Lateral  vibrations  of  drillstring  bottom  hole assemblies are confirmed by sensing longitudinal and torsional accelerations or displacements of the drillstring at or near its top end during rotation and determining the lateral critical speed and displacement of the drillstring from the mode shape of the bottom hole assembly which occurs during forward synchronous whirl and longitudinal shortening of the bottom hole assembly resulting from such whirl.  Lateral motion of the bottom hole assembly, while drilling, is estimated based on longitudinal and torsional measurements at the top of the drillstring.  Radial displacement of the bottom hole assembly due to impacting of the borehole wall imparts a torsional impulse which, together with considerable radial motion, is repeated each revolution.  The lateral or radial motion causes a small axial motion to develop in the bottom hole assembly which results in an axial force on and axial shortening of the drillstring which varies once per revolution.

Abstract: A battery case accommodating a battery is inserted into a battery case housing of a head lamp body.  As the battery case is inserted, one protrusion of a stopper held by a stopper holding portion of the housing moves downward through  an opening.   When  accommodation of  the  battery case is completed,  another protrusion of the stopper as well as the one protrusion returns upward, and the former protrusion is fitted in a recess of the battery case to prevent movement of the battery case.  When the head lamp body is attached to a bracket fixed on a bicycle in that state,  a protrusion of the bracket prevents movement of the one protrusion of the stopper.
