Patent GB-2147477-A (GB)
Title: Data transmitter, data receiver and data transmission system
Inventor: PHILLIPS IAN
IPC: H04L25/493
Filed: 1983-09-28
Abstract: A data transmission system includes a transmitter in which a data signal (1a) is encoded to form a Miller coded signal (1b) which is then differentiated (1e) before being fed to a transmission link, for example a telephone line. Narrow bandwidth lines tend to integrate the signal passed along them (1g) and the original Miller coded signal may be extracted by means of a level sensitive detector. On short lines the differentiated signal is received but this is decodable by use of the same level sensitive detector (1i). Passive differentiation (1e) leads to inefficiencies in the transmitter and it is therefore preferable to perform a pseudo differentiation by producing short pulses of alternating polarity for each level change (1f). A data transmitter and data receiver for a pseudo-differentiated Miller coded data signal are described. <IMAGE>

Title: Rotary cutting tool
Inventor: HOWELL JOHN
IPC: B23C5/00
Filed: 1984-05-03
Abstract: This invention relates to rotary cutting tools, which are held in a chuck when in operation. Chucks commonly used in the art are threaded to accept a tool with a threaded shank which allows the tool to be firmly secured. The threading of tools formed from a single piece of steel is readily achieved and presents no problem. However, for some operations tungsten carbide is required as the cutting material. This material is difficult and expensive to machine. The rotary cutting tool of this invention comprises a two piece construction of a tungsten carbide shank 3 provided with cutting flutes 4 at its working end and secured (e.g. by brazing) to a rear end 1 of machined steel which may be threaded to cooperate with a threaded chuck. <IMAGE>

Patent GB-2151295-A (GB)
Title: Locks using magnetic keys
Inventor: ROGERS JOHN
IPC: E05B47/00
Filed: 1984-12-03
Abstract: The lock has a bolt 2,3 which is shifted by handles on either side of the door, attached to a spindle 4. Movements of the bolt are controlled by two rotatable barrels 8 and 9 intersecting the profiled slots 10 and 11 in the bolt tail. In each barrel a pair of plungers 23 are sprung out into recesses in the surrounding lock body to block rotation of the barrel. Inward movement of the plungers to free the barrel is normally blocked by pairs of magnetic rotors 26A/26B, 26C/26D. To unblock the plungers a correctly coded magnetic key (Fig. 5 not shown) is inserted in the keyway 20 and the key and rotor magnets interact to turn the rotors into positions in which respective arcuate cut-outs 28 in the rotors align with the plungers 23. Turning the barrel now causes the plungers 23 to ride on inclined surfaces in the surrounding body thus pressing in the plungers and permitting rotation of the barrel. <IMAGE>
