Title: Method of coating articles
Inventor: JAMES PETER FINLAY
IPC: C03C17/02
Filed: 1988-10-06
Abstract: A method of coating an article with a glass comprises forming a melt of a glass that is silica-free or has a silica content less than 55 wt % and a low viscosity at the dipping temperature, preheating the article to a degree to suit the particular glass composition, dipping the article in the melt, maintaining the article within the melt for a predetermined period and withdrawing the article from the melt at a predetermined controlled rate. The method is used to strengthen articles, particularly glass articles, by applying a coating having a thermal expansion coefficient less than that of the article.

Title: Compensating for residual strain of a piezoelectric element
Inventor: INOSE TOSHIO
IPC: H02N2/06
Filed: 1989-05-05
Abstract: A system for controlling a piezoelectric element whose strain varies with a voltage applied thereto and which has a residual strain left after removal of the voltage, such that a difference in the amount of the residual strain before and after an energization of the piezoelectric element varies depending upon a hysteresis of the piezoelectric element before the energization. The system is adapted such that at least one preliminary energization of the piezoelectric element is effected, prior to a primary energization cycle of the piezoelectric element, at least where the difference is equal to or larger than a predetermined value. The primary energization cycle includes at least one primary energization of the piezoelectric element for attaining a desired function. The disclosed system is capable of eliminating an error of the actual amount of residual strain of the piezoelectric element from the nominal value, which may arise from different operating conditions of the element, such as energization time, time duration between successive energizations, and temperature variations of the element. <IMAGE>

Title: Control of the manufacture of plaster board
Inventor: CHILDS PETER ALBERT
IPC: B28B19/00
Filed: 1989-10-12
Abstract: To control the manufacture of plasterboard the supervisor enters required board parameters and production rate into a central processor. The processor senses the ratio of liquid raw materials to solid raw materials (AWAT) in a mixer and compares AWAT to a calculated setpoint value (SWAT). The set point value is adjusted in accordance with the difference between AWAT and SWAT. The height of a slurry dam behind an extruder on the boardline is then sensed and compared with a set point value (SDAM). If the sensed value (ADAM) differs from the set point value (SDAM) the setting belt speed (ABEL) is adjusted. The adjusted belt speed is then compared to the desired production rate (SBEL) and the raw materials feed rates varied to compensate for the difference.

Title: Hologram sheet attached to transparent plate
Inventor: ISHIKAWA TOMOHISA
IPC: G03H1/04
Filed: 1989-12-06
Abstract: A hologram sheet (20) attached to a transparent plate (12), such as a reflection hologram sheet attached to a vehicle windshield (10) in a head-up display. The recording medium for the hologram is processed such that a major central area serves as the hologram (22) and that a marginal area (24) remains blank (Fig. 3). The blank marginal area (24) renders the border between the hologram sheet and the transparent plate (12) indistinct to the observer. This effect is further improved by forming a plurality of small spot-like or belt-like hologram regions, in the marginal area, preferably such that the total area of these regions is relatively large in an area adjacent to the central area and becomes gradually smaller in areas nearer to the edge of the hologram sheet (Figs. 4 and 5). <IMAGE>

Title: Tool for installing collapsible wail fittings
Inventor: JACKSON EWART
IPC: B23B51/08
Filed: 1990-09-11
Abstract: The tool comprises an elongate body (10) having an external screw thread (12) along its length. A drilling tip (16) is removably supported at one end of said tool body. and coupling means (26) are provided at the other end of the body. With a collapsible fixing positioned on the body (10), the tool is rotated by a drill or the like coupled to the coupling means (26). Rotation of the tool causes the drilling tip (16) to bore a hole. Continued rotation of the tool collapses the fixing. Once the fixing has been collapsed it is only necessary to reverse the rotation to remove the tool from the collapsed fixing which is then ready to receive and hold a screw therein. <IMAGE>

Patent GB-908929-A (GB)
IPC: F16H13/08
Abstract: 908,929. Friction gear; variable-speed gear. STANLEY-BRIDGES Ltd., and KILNER, S. R. Nov. 6, 1959 [Nov. 5, 1958], No. 39261/58. Classes 80 (1) and 80 (2). [Also in Group XXII] Gearing for use between an electric drill &c. 3, Fig. 1, and a driven spindle 11 comprises planetary balls 9, mounted in a cage 10 fast with the driven spindle and adapted to engage frictionally with a non-rotary reaction track 4 and with a driving race 7, the ball-engaging surface of the reaction track being of shallow configuration so that although when a tool mounted upon the driven spindle is out of engagement with a workpiece the balls lie loosely in the cage, whereby rotation of the driving race does not rotate the driven spindle, &c., as soon as the tool is applied to a workpiece the axial force produced thereby acting on the driven spindle wedges the balls into engagement with the race and the reaction track for torque transmission, the axial force moving the balls radially, while increasing the axial force reduces the speed at which the driven spindle rotates. In a modification, part of the reaction track 4, Fig. 2, is mounted in a spigoted end-cover 1b threaded into a main cover 1a and turned to adjust the force engaging the balls with the driving race, &c.

Title: Determining an instantaneous spatial position of a spherical flying object
Inventor: NISHIYAMA TETSUJI
IPC: G01B11/00
Filed: 1991-05-28
Abstract: A position determining apparatus utilizes, in combination, an irradiator (4), a screen (5) and an optical sensor (6). The irradiator generates a parallel light band (P) to form a linear image region (IR) on the screen. A spherical flying object (2), such as a golf or tennis ball, is made to pass transversely through the parallel light band to form a silhouette (S) within the image region. The position of the silhouette is detected by the optical sensor to determine the instantaneous spatial position of the flying object. The position thus determined may be utilized for example to calculate the initial trajectory angle of a golf ball hit from a fixed position. <IMAGE>

Title: An optical reflector
Inventor: MILNER PETER JAMES
IPC: G02B5/04
Filed: 1992-05-22
Abstract: An optical reflector is formed by an array of reflecting surfaces arranged one behind another in spaced, generally parallel, relation along a main axis of the array. The reflector has entry and exit faces (11, 12) disposed on opposite sides of, and extending along, the array main axis. The spaces between the reflecting surfaces is preferably occupied by a refractive material. In this case, light entering through the entry face (11) is first refracted and then reflected before being refracted again on leaving through the exit face (12). The main extent of the reflector is unlike a conventional mirror, normal to the plane of reflection. The reflector is thus well suited for use as a vehicle external rearview mirror as it has minimal lateral protection. A reflector array may be produced from a stack of elongate elements having optically worked faces.

Title: Quality check for a mobile cellular radio system
Inventor: KALLIN HARALD
IPC: H04W72/08
Filed: 1992-08-21
Abstract: In a mobile cellular radio system, when setting up a new call or when handing over an existing call to a new traffic channel, it is necessary to avoid disturbances on the new traffic channel which can cause poor transmission quality. In order to avoid unnecessary disturbances on the new traffic channel, the signal strength of the mobile station requesting a new channel is measured. In addition, the disturbance levels on the available traffic channels are also measured and then compared with the signal strength of the mobile station requesting a channel. Based on the comparison, a traffic channel is assigned to the mobile station so that the disturbance level on the traffic channel is at least less than or equal to a minimum threshold value. <IMAGE>
