Patent GB-2102207-A (GB)
Title: Electrical circuit assembly
Inventor: CHILCOTT RONALD JAMES HERVEY
IPC: H05K9/00
Filed: 1981-07-17
Abstract: An electrical circuit assembly having a high voltage component 10 encapsulated in a dielectric potting compound 11, and having a metal casing 13, whereby electrical charge is leaked away, has a deformable material 15 intermediate between the casing and the encapsulation, the intermediate material remaining contiguous with the adjacent portions of the encapsulation, and remaining contiguous with at least some of the adjacent portions of the casing, under normally encountered variations of temperature. The intermediate material may be sufficiently electrically conductive enabling the charge to be leaked away at a rate ensuring that discharges do not occur in spaces within the circuit assembly, for example, the intermediate material comprising a foam of a plastics material with an electrically conductive filler. Whether, electrically conductive, or not, the intermediate material may be resilient; and/or may be adherent. <IMAGE>

Patent GB-2087113-A (GB)
Title: Device for voltage regulation in direct current electrical systems
IPC: H02M7/5395
Filed: 1981-10-30
Abstract: A direct current regulator for motor vehicles and the like gives a constant output voltage in the case of a greatly variable input voltage, even when the throughput power is high. It comprises a blocking converter circuit in which a by-pass connection (1), optionally controllable, leads to the secondary winding of the converter transformer (20) from the input (23). In the step-up regulation mode, the transistor (2) is repeatedly switched on and off in the manner of a blocking converter but a proportion of the power to be transmitted is fed to the secondary side by way of this by-pass connection (transistor 1), whilst, in the step-down regulation mode, the blocking transistor (2) is kept off while the by-pass connection (transistor 1) is repeatedly interrupted, the decay current through the secondary winding (5) flowing through a free-running diode (4). <IMAGE>
Patent GB-2091661-A (GB)
Title: Centre buffer coupling
IPC: B61G9/24
Filed: 1982-01-20
Abstract: A centre buffer coupling for locomotives or corresponding machines has a shaft 4 going through the buffer plate 1 and articulated in it, the outer end of the shaft having a coupling head 3. The shaft 4 is supported by a rotatable roller 14 in the opening 2 of the buffer plate 1 between the drawing and pushing springs 9,9' so that the support allows longitudinal movement of the shaft 4 and, in addition to this, the necessary movement of the coupling head 3 in the vertical and horizontal directions. The shaft is prevented from substantial rotation around its axis. The roller 14 avoids the sliding of the shaft 4 on the buffer plate 1, thereby avoiding the corresponding wear. As an alternative to the roller 14, the shaft 4 can be supported by a bar mounted on the buffer plate 1 by an articulated joint. <IMAGE>

Title: Gas-filled excess voltage arresters
IPC: H01T4/12
Filed: 1982-03-17
Abstract: An arrester for the protection of a load connected across a low voltage d.c. supply consists of a gas-filled enclosure 2 containing an electrode structure which defines first d1 and second d2 discharge gaps, the first gap d1 having a lower breakdown voltage than the second gap d2 due to its electrode spacing for the enclosure, and to at least one of the electrode surfaces which defines the gap d1 having a low work function. The electrons produced in the discharge of the first gap assist in the initial breakdown of the second gap. The spacing d, between the electrodes 3 and 5 is selected to beat the Paschen minimum. A resistor 11 connected to electrode 5 is of such value that a small current, i.e. nanoamps, flows through the arrester, providing electrons for priming the gap d2 without significantly loading the supply. <IMAGE>

A support member 8 may be provided either exteriorly or interiorly or both of the window member 4 against which the window member is urged in use. Fluid pressure support may be by means of an internal pressure source, or by means of ram air pressure. <IMAGE>

Title: Fuel supply system for a diesel engine
Inventor: JEFFERIES RALPH GILBERT
IPC: F02M37/20
Filed: 1983-05-17
Abstract: Fuel for a diesel engine is pumped by pump 8 from a main fuel tank 7 to a reservoir 1 from where it is fed via filter 13 and lines 15, 16 to a fuel injection pump 14 of a diesel engine. Excess fuel is returned via leak off rail 4 and lines 5, 6 to the main tank 7. A detector 2 detects the level of fuel in reservoir 1 and when the fuel falls to a predetermined level actuates a relay 3 to operate a solenoid 17 which shuts down the engine. Air entrained in the fuel supply by pump 8 escapes from reservoir 1 via outlet 10 to return to the main tank 7 via line 6. The reservoir 1 is preferably kept above the level of rail 4 to prevent air at outlet 10 of the reservoir entering rail 4. By shutting down the engine before reservoir 1 runs dry, fuel injection pump 14 always remains primed. <IMAGE>

Title: Process for preparing indoles
Inventor: KUDOH AKIO
IPC: C07D209/08
Filed: 1983-06-22
Abstract: Indoles are prepared by reacting an aniline and an ethylene glycol in the gas-phase in the presence of a catalyst, the reaction being carried out at superatmospheric pressure, e.g. in the range 1.1 ô 10<5> to 1.0 ô 10<7> Pa, and e.g. at a temperature in the range 200 to 600 DEG C. The aniline and glycol can be passed over the catalyst at a molar ratio of 1:0.01 to 5 and at a feed rate of 0.01 to 10 per hour in terms of liquid hourly space velocity. By conducting the reaction at superatmospheric pressure, the selectivity and catalyst life are improved.

Title: Air-cooled hydraulic actuator means for machine tool rotary clamping devices
Inventor: ROHM GUNTER HORST
IPC: B23B31/30
Filed: 1984-01-09
Abstract: For removing heat generated by relative rotation between a stationary connecting housing (16) and a rotary clamping cylinder (1) a cooling air flow passes substantially axially over the connecting housing (16) and is produced by fan blades (7) which rotate with the clamping cylinder and which are disposed on the peripheral surface (8) of the cylinder housing (1). The fan blades (7) are each inclined through at least 45 DEG  relative to the cylinder axis (12). Cooling air flow flows in an annular space (17) defined outwardly by a flow guide casing (10) which extends axially over the fan blades (7) and at least a part of the connecting housing (16) and which nowhere reduces the width of the annular space (17) in comparison with the flow cross section in the region of the fan blades (7). Two diametrically opposed blades (7) provide an adequate cooling action even at high speeds of rotation. <IMAGE>

Title: A unit for forming, and a method of installing, a damp-proof course
Inventor: SHEFFIED COLIN JOSEPH
IPC: E04B1/64
Filed: 1984-03-07
Abstract: The unit 1 comprises a web 2 of a damp-proof material and support means 3 for receiving a suitable filler material, so that when the filler material is set, central web 2 is supported through its whole surface-area. The support means may be formed from a perforated or perforatable material: thus the V-shaped sections shown are caused to open once the receptacle defined between support means 3 and central web 2, on both sides thereof, is filled. Thus filler then escapes through the perforations and fills any gaps in the wall, and secures the unit. Support means 3 may be a tube of material arranged to surround web 2.   The DPC may be installed by forming in a wall a slit cavity, inserting a unit 1 and filling the unit with settable filler material via inlets 9. This procedure is then repeated along the wall, and joints between adjacent sections are sealed. <IMAGE>
