Title: Lamp junction method of assembly thereof and lamp
Inventor: ULMANN PHILIPPE
IPC: F21V17/02
Filed: 1985-06-04
Abstract: In order to be able to substantially pre-assemble the functional components of a lamp before the components of the lamp which are visible from the exterior, such as lamp shades, lamp support members and so forth are assembled thereto such that the same lamp junction can be employed for different external appearances of lamps, the lamp junction comprises a central support junction upon one or both sides of which a connection member can be mounted. Each such connection member forms a guide for an electrical connection lead and serves to rotatably support an anchorage member for a lamp shade member upon the connection member. After assembling and electrically wiring the central support junction, the connection member, the anchorage member and a lamp socket, the lamp shade member, a cover sleeve for the central support junction and the lamp support member can be subsequently mounted to the lamp junction.

Title: Oven door fastenings
Inventor: CLEWES BRIAN
IPC: E05B53/00
Filed: 1986-04-18
Abstract: A cooker oven door (3) is held in a closed position against a spring by a pivotal latch member (11) mounted on the cooker so as to be engageable with the door (3), the latch being actuated by the normal operation of control means (9) mounted on the cooker at a location remote from the latch member (11) and connected to the latch member (11) by a suitable linkage (13).

Title: Determining the actual artificial alpha aerosol activity concentration in air
Inventor: KREINER HANS-JUERG
IPC: G01T1/178
Filed: 1989-01-13
Abstract: An alpha energy range discrimination (AERD) method is used for continuous investigation of the content of artificial alpha aerosol activity concentration in a volume of air or in air streams. Artificial and natural nuclides are collected onto a filter X from a known volume of air. The  alpha -particles from both artificial and natural nuclides are detected by a proportional counter 2, while a foil 3 prevents connecting of artificial nuclides by proportional counter 2. The device is calibrated so that the  alpha  activity of the artificial nuclides alone can be calculated from the two counter readings and constants specific to the device which have been determined by the least square fit.

Abstract: An environment table object, associated with a process object, includes a control stack to save the state of a calling execution environment to be restored on a return from the called execution environment. A caller's domain object 100 includes access descriptors that reference objects which define regions 0 and 1 of the called execution environment, and a subsystem ID that points to an entry in the environment table. An entry in this table specifies the object that defines region 2 of the called execution environment, and the frame pointer of the topmost stack frame in the called environment. The caller's domain object 100 also includes a supervisor Stack Pointer that is a linear address for the supervisor stack used when invoking a supervisor call in the user mode (instead of the stack pointer in the current frame) to locate the new frame. The domain object 100 further includes Procedure Entries that specify the type and address of the called procedure. Each of the procedure entries includes a Procedure Entry Type field that indicates the type of procedure to be invoked, either a supervisor procedure or a subsystem procedure, and an offset into the called execution environment to specify the first instruction of the called procedure. <IMAGE>

Title: Electrical switches
Inventor: BRIDGESTOCK BRUCE STEWART
IPC: H01H37/54
Filed: 1991-01-22
Abstract: An electrical switch incorporating a snap-acting actuator 5 for actuating switch contacts 4, 9 has a latching mechanism for ensuring that the switch, once operated, does not auto-reset. The latching mechanism comprises a spring loaded moulded plastics latching member 11 which is received in click-fit manner in a recess in a moulded plastics body part 1 of the switch. The latching member 11 is normally clear of a movable contact carrying member 5 but upon switch operation it is displaced against its spring bias to accommodate the movement of the movable contact carrying member 5 and thereafter it resiles into a position wherein it interferes with the movable contact carrying member 5 to prevent resetting of the switch. The actuator 5, which may be bimetallic, may constitute the movable contact carrying member 5 or act on a separate member. <IMAGE>

Title: Movement control.
Inventor: DANBURY RICHARD NEIL
IPC: G05B19/416
Filed: 1991-02-22
Abstract: It is often the case that actuators are used inefficiently so that it is necessary to use a more highly rated actuator than should have been the case. The present invention provides methods and apparatus ensuring more efficient use of actuators in point-to-point positioning of loads. The actuator is controlled by control means including data handling means (40) for obtaining and storing information relating to the speed and position of an actuator (20) during a move. Drive means (22) selectively accelerate and decelerate the actuator (20). The control means also includes processing means (36) arranged to predict from the speed and position information a deceleration path for said actuator and to cause the drive means (22) to decelerate the actuator when the predicted deceleration path intercepts an actual acceleration path of the actuator. Efficient use of actuators means that better performance can be obtained from a given actuator, or that the actuator in a positioning system can be replaced by one of a lower rating whilst still maintaining performance.
