Title: Computer-controlled cordless telephone
Inventor: BECKER WILLIAM RICHARD
IPC: H04W52/02
Filed: 1987-02-16
Abstract: A computer-controlled cordless telephone system having a base unit and a handset unit provides for increased functionality in communications between the base unit and the handset unit, and also provides a controlled power-up/power-down mode of operation for the handset unit. Increased functionality is achieved by employing a message format for control signals transmitted between the base unit and the handset unit in the form of frequency shift keyed (FSK) signals which include a data field. This data field may be in the form of either opcode data or digit data, thereby allowing for many different commands or functions. Power to a computer, a receiver and certain other selected circuitry in the handset unit is controlled to minimize power consumption when the handset unit is in an out-of-cradle-and-standby state. Power to other nonessential circuitry in the handset unit is turned completely off during this state. The handset unit automatically turns on to a full operating mode from the alternating power-up/power-down mode in response to events such as (1) a user depressing a key no the keypad of the handset unit for either initiating a telephone calls or paging the base unit, and (2) the base unit detecting an incoming ringing signal on the telephone lines.

Title: Improvements relating to liquid crystal displays
Inventor: VIEWING DAVID
IPC: G02F1/13
Filed: 1987-05-08
Abstract: An item of electronic equipment such as a portable microcomputer has a liquid crystal display (36) mounted on a printed circuit board (44) which is directly secured to a housing (30) of the micro computer. The liquid crystal display is mounted behind an opening (32) the edges of which serve as a bezel for the liquid crystal display.

Title: Producing cylindrical metallic friction elements by sintering powder
Inventor: HILLIER HAROLD JAMES
IPC: F16D69/02
Filed: 1988-02-11
Abstract: A generally cylindrical brake band comprises a radially split, steel element to the radially inner circumferential surface of which is secured a generally cylindrical friction element. The friction element is of low density and is produced by a method comprising pouring powder friction material onto a support member, sintering the powder material in a sintering furnace on the support member and removing the sintered material from the support member, the sintered material being formed to its generally cylindrical shape either before or after the sintering operation. The powder friction material may be poured onto a planar support member and sintered thereon in the sintering furnace, the resulting planar sintered friction material subsequently being cut to size and formed to its cylindrical shape. Alternatively, the powder friction material may be poured into a cylindrical mould and sintered therein in the sintering furnace, the resulting cylindrical sintered friction material subsequently being removed from the mould.

Title: Aggregate dryer
Inventor: NISHIO KATSUHIKO
IPC: F26B11/02
Filed: 1989-04-10
Abstract: An internally bladed elongate inclined rotary drum 14 for a dryer 10 of an asphalt plant is partitioned at 26 into the cold hopper side 30 (upper rear section) and hot hopper side 30 (lower front section). Duct 28 extends through partition 26 to convey hot gases from one section to another. New aggregate feed holes 38 and waste material discharge holes 40 are provided in the circumferential walls of the drum below and above position 26 respectively, with a common non-rotary cover housing 42 around their peripheries. A new aggregate feeder 44 above cover 42 selectively feeds new aggregates into the feed holes 38 until they discharge from the new aggregate discharge part 24 a waste (recycle) material removal discharge port 50 at the base of the cover 42 selectively discharges the recycle materials fed into the rear upper section of the drum and escaping through the discharge holes 40. If port 50 is shut, recycle materials accumulates within the cover 42, eventually being taken up by holes 38 to be part of the material laid. Thus new aggregate only, or a mixture of new and recycled, can be laid as desired. <IMAGE>

Title: Preventing fraudulent operation of single-use-card activated machine
Inventor: STANLEY WYATT JAMES
IPC: G07F7/00
Filed: 1990-03-16
Abstract: A coded card operated machine, eg a game machine, does not return a validated card to the user but passes it to a hopper 34 via a two directional path which includes a slot 48 (Fig 2) to prevent fraudulent stringing of the card. The first part of the path passes sensors 12, 26 (Fig 1) and a reading head 20 and the second part of the path is defined by a surface 30, arranged below the level of the first pan of the path and onto which the card falls freely. The slot 48 is of such dimensions that an inclined card will jam therein, eg if inclination is caused by pulling on string attached to card. A validation signal is credited on arrival of card at pivotally mounted member associated with a sensor 42 at entry to hopper only if sensors 12 and 26 are both clear. The card feeds in grooves 4 (Figure 1) past the sensor 12 and if a card is not deemed acceptable by reading head 20 a microcomputer 14 reverses feed rollers 16, 18 to return the card to user. An alarm may be signalled on line 46 if timing of sensors 12, 26, 42 is such as to indicate withdrawal of card. The card reader may include a battery. <IMAGE>
