Title: Electrical appliance connector
IPC: H01R13/502
Filed: 1980-01-21
Abstract: The connector comprises a contact retaining housing 10 formed from a temperature resistant plastics material, at least one contact 13, 14 located in said housing, a cable 16 connected to said contact, a cable grip 17 and a moulded plastics portion 19 enveloping the end of the housing from which the cable emerges, the cable grip and the adjacent portion of the cable. To produce the connector, the contact is permanently secured to the cable and is located in the contact retaining housing, so that the cable emerges from the housing and is anchored thereto by means of the cable grip. The plastics portion is then moulded about the end of the contact retaining housing, the cable grip and the adjacent portion of the cable, in order to seal the assembly together. The cable grip 17 may be a separate part fitted on spigots 18 (Fig. 2) of a single-part housing 10 and engaging a metal ring 9 swaged on cable 16. Alternatively the cable grip 17 may be integrally formed as a portion of a two-part housing 10a, 10b with formations 24 to grip the cable (Figs. 4 to 6). One housing part 10a of a further embodiment (Figs. 7 to 9) has a front end projection 30 engaging in a recess 31 in the second housing part 10b so that the parts 10a, 10b may be closed in hinge-like manner until spigots 22 on 10a engage holes 25 in 10b whereby the housing subassembly is held together mechanically before the portion 19 is moulded therearound, walls 32, 33 (with wire-receiving channels 34) integral with parts 10a, 10b sealing off the rear of the housing to prevent ingress of plastics during such moulding. In this embodiment the cable is gripped by wedge shaped edges 37 (Fig. 7) of a U-shaped member 35 integrally joined to part 10a by struts 36, the open end of member 35 being closed by a tab 39 (Fig. 8) integrally joined to part 10b by a tongue 40. <IMAGE>

Title: Flue damper control system
IPC: F23N3/08
Filed: 1981-02-12
Abstract: A flue damper is mechanically driven through a sensor control to change the physical position of a damper within a flue associated with a furnace or other combustion device. After the demand for ignition of the furnace, the flue damper is rotated slowly into the full open position whereupon ignition of the furnace is permitted. After the demand has been satisfied, the ignition is ceased and at a predetermined time thereafter the damper is slowly moved to the closed position whereby to inhibit completely, in the cases of oil fired devices, and to a substantial degree (a maximum of 90%), in gas fired devices, the orifice size of the exhaust flue thereby preserving the residual heat within the boiler or fire box which would otherwise escape through the flue into the atmosphere. Such device decreases, in excess of 15%, the amount of energy consumed by reducing the cool-down effects of the fire box or boiler. <IMAGE>

Patent GB-2113087-A (GB)
Title: Folding umbrella
Inventor: TSUN ZONG WU
IPC: A45B25/02
Filed: 1982-01-14
Abstract: A frame for a foldable umbrella has main stretchers 23 pivotally connected at their lower ends with a lower boss slidable along the umbrella shaft, and pivotally connected at their upper ends with ribs 24, the main stretchers 23 being pivotally connected intermediate their ends with the lower ends of respective auxiliary stretchers 21 which in turn are pivotally connected at their upper ends to an upper boss fixed to the shaft. By contrast with known arrangements, however, each auxiliary stretcher is in the form of a thin strip which, at a position just above its pivotal connection with a tension link 20, is cranked so that the upper portion of stretcher 21 is offset with respect to, but parallel with, the lower portion and the plane of pivotal movement of the main stretcher, rib 24 and link 20. The slots in the upper boss which receive the auxiliary stretchers are corresponding offset. As a result, in the folded condition, the upper ends of stretchers 21 are disposed circumferentially between the upper ends of stretchers 23, instead of the main stretchers being disposed radially outwardly of the auxiliary stretchers as is conventional, so that the radial dimensions of the folded umbrella at the tail end are reduced. The heads 22 of the ribs 24 lie entirely below the upper boss, rather than radially outwardly thereof. <IMAGE>

Title: Angular resolved spectrometer
IPC: H01J49/48
Filed: 1981-05-08
Abstract: An angular resolved spectrometer is provided which is capable of analysing the energy of charged particles from an analysis source and simultaneously obtaining spectra with a resolution of +/- 1.0` for a range of angles of emission of the order of 340`. Concentric toroidal electrode sectors (4, 5) move charged particles with emission angles -//c<uo>u<//c<+//c<uo>u, any ss angle, and a chosen energy, entering at a path midway of the inlet end of an open-ended annular toroidal-contoured passageway formed by said concentric toroidal sectors (4, 5) and between which an electric field is established, so that charged particles with said energy and angles (//c, ss) will be refocused such that those charged particles with differing //c angles are strongly refocused but those charged particles with differing ss angles are only weakly refocused, thereby to retain the required ss angular information at the //c focus plane and provide a focus of charged particles into ring form. A charged particles position-sensitive detector (11) then registers the focus of charged particles in ring form and generates signal pulses determined by the position of arrival of the charged particles on the detector (11). Means which measures differences in arrival times of the signal pulses is preferably employed to determine the angle ss at which the charged particles were emitted from said analysis source.

Title: A method for automatically regulating the time of combustion initiation in an internal combustion engine
Inventor: DOUAUD ANDRE
IPC: F02D41/40
Filed: 1982-06-09
Abstract: A method is provided for automatically controlling the ignition time in a spark ignition engine or the injection time in a compression- ignition engine wherein at least one phenomenon characteristic of the running conditions of the engine, such as the occurrence of the peak pressure in a cylinder in a certain angular interval of the crankshaft, or detection of passage of the flame front through a reference position of a combustion chamber, is detected. A statistical, e.g. mean value representative of at least P measurements of said phenomenon is determined and this value is used to modify the time of combustion initiation so that the statistical value adops a predetermined value corresponding to the desired running conditions. Accelerometers or ionisation probes 64a-d are connected to circuit 66a-d which detect the angular position of the crankshaft at which the phenomenon occurs and supply signals to processing circuits 69a-d which determine the statistical value of the crankshaft position. Circuits 70a-d determine the ignition advance such that the phenomenon occurs at the predetermined value. During starting, an engine speed sensor 76 or an engine load, temperature or throttle position sensor 77 controls the ignition advance. A knock sensor 78 provides a priority signal to control the ignition advance to prevent knocking. <IMAGE>
