Abstract: 861,483. Double apron drafting arrangements. RIETER & CIE, A.G., J.J., June 26, 1958 [June 29, 1957], No. 20590/58. Class 120(2) A double apron drawing arrangement has the lower apron reversing bar provided with differently shaped surfaces that can be brought into apron supporting position. In one form, the reversing bar 17 has a generally prismatic configuration with the three surfaces 40, 41, 42 having different shapes. Each end of the bar 17 has an equilateral prismatic protruberance 18 arranged to rest in a complementary notch 19 of a support 2. By turning the bar 17 on its axis or through 180 degrees in a plane normal to its axis, six operating positions of the bar may be provided. In another embodiment, the bar 17 has cylindrical protruberances that are clamped in supports so that the bar may be held in any angular position. In a further form, the bar 17 is held in supports adapted to receive conventional reversing bars by means of an intermediate member. The bar 17 may have other numbers of surfaces than three. Specification 812,335 is referred to.

Title: Electric arc interrupter
Inventor: CRISP GEORGE FRANCIS
IPC: H01H33/18
Filed: 1988-10-15
Abstract: An arc interrupter 5 mounted in a housing between two conductors 2, 4 comprises a fixed contact 7, two arcing electrodes 17, 18, one or more arc-driving permanent magnets 23, 24 which are coaxial with arcing surfaces 19, 20 of the electrodes 17, 18 and a movable contact 15 mounted for guided movement between a make position and a break position. The fixed contact 7 is electrically connected to and located outside one of the electrodes 17 and the movable contact 15 is electrically connected to and located outside the other electrode 18. During opening of the interrupter 5 an arc is struck between the contacts 7 and 15 after which it moves between surfaces 19, 20.

Patent GB-2233487-A (GB)
Title: Vehicle protection system
Inventor: JOSELOWITZ STEFAN BRIAN
IPC: B60R25/04
Filed: 1989-06-23
Abstract: The system comprises a transmitter 10 on the person of a driver and a receiver 13 on the vehicle. The transmitter sends a coded signal which when received enables the vehicle to be driven. In the absence of such a signal, the vehicle is disabled as by closing a valve 15 in the fuel line. Thus when the vehicle is hijacked and the driver left behind, the vehicle comes to a stop when the signal from the driver is no longer received. The transmitter may be operative to transmit the coded signal only upon receipt of a coded signal from a transmitter on the vehicle, Fig. 2 (not shown). The transmitter carried by the driver may be a transponder, Fig. 3 (not shown). <IMAGE>

Abstract: An isolatable contact for a removable electrical appliance comprises a contact pin (15) carried on a mounting plate (14) constructed and arranged to be moved against a biassing pressure (15) from a rearward position in which the pin is retracted in a housing to a forward position in which the pin protrudes from the housing eg into a slot (11) to engage a corresponding contact on the appliance, in which the pin is displaceably mounted on the mounting plate for movement between a position in which it is isolated from an electrically live connection (13) and a position in which it is in contact with said connection, the pin being biassed (17) towards the isolated position and the arrangement being such that in use the presence of the appliance displaces the mounting plate to the forward position and substantially simultaneously displaces the contact pin to the contact position. The plate (14) may be moved by an earth pin of a cordless iron camming against a bar (18). Plural contacts (16) engage contacts on the iron before the iron contacts push the biassed contacts (16) onto the live connections (13). The latter may alternatively brush over an associated pin contact having an insulated and a conductive position. <IMAGE>

Title: Co-ordinate adressing of liquid crystal cells.
Inventor: CROSSLAND WILLIAM ALDEN
IPC: G09G3/20
Filed: 1990-09-11
Abstract: A co-ordinate addressed bistable liquid crystal cell is switchable between its two stable states by oppositely directed electric potential differences applied across the liquid crystal layer thickness between a front-plane electrode and the members of a co-ordinate address array of electrode pads of an active back-plane. Refresh data is compared with currently displayed data so that only those pixels scheduled for switching are subjected to switching stimuli. The electrode pad of a pixel scheduled for switching is taken from a potential of the front-plane electrode to a different potential by connection to a voltage source. It is then electrically isolated from that voltage source for a further period before its potential is restored to that of the front-plane electrode. This enables rows of pixels to be addressed with a line address time considerably shorter than the time necessary to effect full switching.
