Title: Friction material and carrier plate assembly
Inventor: BOLTON JOHN STEPHEN
IPC: F16D13/64
Filed: 1987-04-10
Abstract: A friction material and carrier plate assembly 2, which may be used in the construction of a driven plate for a friction clutch, comprises a carrier plate 4 having radial spokes or paddles 14A, 14B which are resiliently pliable axially of the carrier plate. The paddles 14A alternate with the paddles 14B and constitute a set splayed apart from the set formed by the paddles 14B. An annular resilient friction facing 20 is bonded by inelastic adhesive to the set of paddles 14A and another annular resilient friction facing 22 is bounded by inelastic adhesive to the set of paddles 14B. Rubber cushioning 24 formed by strips of silicone rubber 24P, 24Q is bonded between the paddles 14A and the friction facing 22 and between the paddles 14B and the friction facing 20. Rotary motion can be transmitted from the friction facings to the carrier plate and vice-versa through the inelastic bonds thus avoiding the application of shearing stress to the silicone rubber 24. <IMAGE>

Title: Automatic density control in electrostatographic copiers
Inventor: DAVIDSON JAMES R
IPC: G06K7/00
Filed: 1987-12-11
Abstract: A bar code scanner or reader 106 is used for automatic density control in electrostatographic copiers. A test patch composed of a succession of different voltage levels on a photoreceptor 104, (corresponding to lines of a bar code), are arranged in order that the number of lines developed to a visible state are used to produce proper development control. As an example, assuming five lines, the first three would be developed to visibility when toner concentration (developability) is normal, and only two lines developed to visibility if a standard addition of toner is needed. The presence of only one line might call for a larger-than-normal toner addition, and a count of zero or more than three lines trigger appropriate signals to the operator. The lines of various voltages could be generated in several ways, such as a small transparency or slitted screen 100 with a separate light source 102, a transparency intermittently introduced into the path of the exposure light, an opaque test patch adjacent the document area for exposure through a lens, or a small charging device intermittently energized to various voltages. <IMAGE>

Title: Electric torch
Inventor: BEAVER GEORGE DAVID
IPC: F21L4/00
Filed: 1988-02-29
Abstract: A torch comprises a body (1) having end regions to which are attached respective end cap assemblies (2F, 2R,) for forward and rearward beams respectively. The body (1) houses two individually operable power supplies. Each end cap (2F, 2R) comprises a bulb (8), a reflector (19) and a lense (3 (2F), 6 (2R)). The lense (3) is clear to give a clear or white forward-beam, while the lense (6) is red to give a red rearward-beam. Each end cap assembly (2F, 2R) can be secured onto either end of the body (1) so that they are completely interchangeable. On failure of one of the power supplies (generally that associated with the rearward beam), it is a simple matter to unscrew the end assemblies and reattach them to opposite ends of the body (1) so that the forward beam can be maintained in an emergency until it is possible to change the batteries. <IMAGE>

Title: Reports having identification data and printing thereof
Inventor: SPEISER ALEXANDER
IPC: G06Q30/00
Filed: 1988-12-30
Abstract: A bill form indicates its number by bar code and magnetic ink characters. When reading a utility meter, a meter reader uses a bar code reader 26 to enter the number of the next form into a portable computer 24 and calls up customer data (loaded into the portable computer from a main computer 30) and enters the meter reading. The portable computer prints 22 the bill on the form. The customer 32 takes the form to a bank 34 to pay. The bank sends part of the form to the utility company where the magnetic ink characters are read 36 to give the form number which is correlated in the main computer 30 with the form numbers provided in association with customer identifications by the portable computer, to identify the customer and credit his account. A keyboard may be used instead of the bar code reader, or a bill printer counter. Optical characters are also mentioned. <IMAGE>

Title: Magnetron sputtering of magnetic materials in which magnets are unbalanced
Inventor: FRANKS JOSEPH
IPC: C23C14/34
Filed: 1991-02-18
Abstract: A magnetron for sputtering of magnetic materials has a ferromagnetic core with an unbalanced arrangement of magnets providing a plasma entrapping field over the target. In an unbalanced magnetron the magnets of one polarity are not balanced by magnets of the opposite polarity of an equal total strength. The unbalanced arrangement enables the ferromagnetic target to be used without any artificial non-uniformity being introduced into the target to provide the field lines above it. In an unbalanced magnetron some lines of force tend to travel outside the target disc above its surface, in contradistinction to a balanced magnetron where the lines of force tend to travel within the target disc when it is of magnetic material, and thus are useful to effect the plasma (Fig. 4). <IMAGE>

Title: Programmable telephone
Inventor: TAPPING IAN ADRIAN
IPC: H04M1/2745
Filed: 1991-10-04
Abstract: A telephone includes an EEPROM memory (28) for storing data, and a microcontroller (14) for controlling operations. The EEPROM (28) contains data for different operating protocols, so that the telephone can be readily adapted for use in different telephone systems. The EEPROM (28) draws a (small) line current when the telephone is in use, but requires no current to maintain its memories, so no standby power is required. Particularly if the telephone is for use in noisy environments, there can be a mute/boost feature (30) whereby the receiver gain is boosted and the microphone is simultaneously cut off. This may be effectuated by means of the EEPROM (28). <IMAGE>
