Patent GB-2080788-A (GB)
Title: Plaster coating composition
IPC: C04B28/14
Filed: 1981-07-31
Abstract: The possible emission of hydrogen sulphide from building materials incorporating a sulphide-containing constituent is suppressed by applying a surface covering composition containing gypsum plaster and a metal compound e.g. zinc oxide capable of reacting with hydrogen sulphide to form a stable sulphide, and allowing such compound to react with hydrogen sulphide evolved by a sulphur containing component contained in the structure or in the composition itself. The sulphide containing constituent may be blast-furnace slag, or pozzolan.

Title: Fuel injection pump for internal combustion engines
IPC: F02M59/44
Filed: 1981-11-23
Abstract: The pump comprises a housing 1 in which are mounted cylinder bushes 2 with pump pistons 6 which are provided with oblique control edges. Each bush 2 has a throughflow aperture 3 which is controlled by the control edge of the pump piston 6 and which extends parallel to the axis of a cam shaft (not shown) driving the fuel injection pump. A portion of the fuel suctioned by the pump piston flows back through the aperture 3 under high pressure into the fuel duct 4 in the pump housing. A cylindrical collar 5 is provided on the external periphery of the bush 2 at most one mm above the upper point of the throughflow aperture 3. The collar 5 deflects the flow of the fuel issuing at the aperture 3 and effects damping of the fuel jet whereby cavitation is prevented. In an alternative construction the collar 5 is angled towards the aperture 3. <IMAGE>

IPC: F21V5/00
Filed: 1982-08-20
Abstract: A vehicle lamp assembly consists of a light source 14 in a parabolic reflector 10 arranged to direct light on to a composite element 16. The composite element 16, has outer and inner component 18 and 20 separated by a zig zag like airgap, having alternate sections pointing to which are horizontal and 24 which extend at an angle such that downwardly directed light from outside the lamp suffers total internal reflection at such airgap.

Title: Valve assemblies
Inventor: CLEMENTS HUBERT JOHN TOPHAM
IPC: A62C13/76
Filed: 1982-11-09
Abstract: A valve assembly has a casing 10 with an inlet 14 and an outlet 11 isolated by a valve member 19. The valve member 19 has a pilot valve member 24 associated therewith. The valve members can be opened by a valve operating assembly 31 which includes an axially movable operating rod 38.

Title: A machine for packing continuously moving articles with a strip of heat-shrinkable material
Inventor: GAMBETTI MARIO
IPC: B65B11/10
Filed: 1984-02-22
Abstract: A machine for packing articles uniformly spaced along a continuously moving conveyor and in which strips of heat-shrinkable material are successively cut from a supply strip of the material such that the strips project from two lateral faces of the articles, and the strips are fed in sequence by a suction feed device across the path of a continuously moving conveyor and between spaced belt sections 6 and 7 defining said conveyor so that each strip is thereby folded with a U-shaped configuration around the bottom, front and top faces of each article. The adjacent zones of the two belts are wound on at least one pair of respective return rollers 24, 25 and 27, 28, the rollers of the two sections being supported by a common carriage which is movable in a reciprocating manner parallel to the direction of transport. Folding of the strip around the article is completed by overlapping the ends of the strip, this being achieved by feeding the trailing portion of the strip into the gap between the two conveyor sections and then moving the carriage to adjust the position of the gap along the conveyor. The suction feed device is also movable in a reciprocating manner both vertically and horizontally. <IMAGE>

Filed: 1984-05-11
Abstract: Apparatus for correcting or compensating for the tracking error of the pivotally mounted (1) tone arm (23) of a phonograph includes a first intermediate member (9) to which said tone arm (23) is pivotally (1) connected, a second intermediate member (12) which is rotatably connected to the first intermediate member (9) by a belt (18) and pulleys (13) which are sized in such a way that a photodiode source (21) and a photodiode detector (22) both carried by the second intermediate member (12) will tend to be indirectly moved by a motor to maintain them substantially constantly in register with a point on the tone arm (23). A slotted mask (24) carried by the tone arm (23) is interposed between the source (21) and the detector (22) and its slot defines a central "null" position in which said motor will not be driven when the required relationship exists. Deviation in either direction will cause the motor to be driven to re-establish this relationship. An insignificant maximum tracking error below 0.1 DEG can readily be attained. Other constructions in which the second intermediate member (12) is omitted and in which the means to control operation of the motor are differently constructed and arranged are described and illustrated. <IMAGE>

Title: Decoder apparatus
Inventor: EMERY SIR PETER
IPC: H04N7/16
Filed: 1984-11-07
Abstract: Decoder apparatus for broadcast television coded signals, includes a decoded circuit 17 arranged to receive such coded signals through an input co-axial plug 6. The decoder circuit includes a switch to activate or inactivate the decoder circuit in response to the validity or invalidity of a card inserted into a slot 13 in the apparatus. A card reader-writer 18 reads information from a magnetic stripe on the card and feeds it to a logic circuit 20 where it is compared to determine validity or invalidity and a signal given to the switch. As decoding occurs, decoded signals are passed to a normal television aerial lead 12 and a clock informs the logic circuit of the time during which the decoder circuit is activated. This is decremented from a period read from the card as valid time remaining and when a card is removed, the original time remaining less the time of activation, i.e. the decremented time, is recorded in the magnetic stripe of the card for future use. <IMAGE>
