Title: Tank washing machine
IPC: B05B3/14
Filed: 1981-04-10
Abstract: A tank washing machine comprises nozzle (13) which is rotatable and pivotable to direct a wash jet at the walls of a tank the rotation and pivoting of the nozzle being caused by a drive shaft (31) driven by reversible hydraulic motor (25) via worm (27) and worm wheel (28). The drive shaft causes rotation of the nozzle housing about a vertical axis. A star wheel (47) on shaft (45) in the nozzle housing strikes projection (48) on stationary flange (12) upon each rotation of the nozzle housing to cause, through worm and worm wheel (44), rotation of shaft (43) and thus pivoting of the nozzle (13). Settable limit means (53) comprising nuts (54), (55) on threaded shaft (51) associated with lever (61) and valve stem (57) are provided so that when the noise reaches a set angular pivoted position, the direction of rotation of the hydraulic motor is reversed via appropriate hydraulic control means. <IMAGE>

Title: Switch mechanisms
IPC: H01H3/02
Filed: 1981-04-15
Abstract: A switch mechanism includes a cam follower member (6) having at least one protrusion with a convex surface. The cam member (6) is operatively connected to a switch actuator (5) and a grooved cam actuator (7) is provided for the convex surface of the cam member (6). The cam actuator (7) has at least two bridging members (8) bridging the groove thereof and when the switch is in its "on" position the convex surface of the cam member (6) is positioned between the bridging members (8) within the groove of the cam actuator (7). When so positioned, any rectilinear movement of the cam actuator (7) causes rotation of the cam member (6) so that the switch is turned to its "off" position. When the switch is in its "off" position it cannot be returned to its "on" position by rectilinear movement of the cam actuator (7) because there is abutment of the cam member (6) against at least one of the bridging members (8). The mechanism removes the danger of reactivating apparatus controlled by the switch mechanism after it has been switched off in, for example, an emergency. <IMAGE>

Patent GB-2082422-A (GB)
Title: Television ghost detection and cancellation system
IPC: H04N5/21
Filed: 1981-08-06
Abstract: A ghost detection and cancellation system is provided in which the horizontal sync pulses of a first sequence of lines (lines 10 and 11) in the vertical retrace interval are used (280) as training signals for the detection and verification of the presence of a ghost signal. This detection procedure results in the development of a signal which reliably indicates the time location of the ghost signal with respect to the main television signal. The location indication signal is then used to select (292) the appropriate tap of a tapped delay line (290). The delayed video signal from the tapped delay line is then applied to the control amplifier (302) of a ghost canceller for the generation of a pseudo-ghost signal (at A) during a subsequent line or lines (lines 12 and 13) of the vertical retrace interval. The pseudo-ghost signal is combined (320) with the original video signal to cancel its ghost signal component. By sequentially performing ghost detection and cancellation during numerous lines of the same vertical retrace interval, ghost detection and cancellation is quickly and accurately achieved. <IMAGE>

Patent GB-2119886-A (GB)
Title: Self-locking nuts
Inventor: ELLIS ALAN ELGAR HERBERT
IPC: F16B39/286
Filed: 1982-05-05
Abstract: A self-locking nut has the end face machined to give a V-shaped or other concave profile, symmetrical about an axial plane of the nut, thus to define a pair of flanks 14, 15. Two slots 17, 18 are associated one with each flank 14, 15 respectively. As the nut is run down an externally screwed member with flanks 14, 15 leading, the nut offers no increased resistance to turning as compared to a plain nut, when however the nut is tightened against a surface, the flanks 14, 15 are deformed towards the main portion of the nut body, closing the slots 17, 18 and deforming the threaded bore of the nut in the region of the slots, so locking the nut on to the externally threaded member. <IMAGE>

Patent GB-2121307-A (GB)
Title: Solvent reclamation apparatus
Inventor: ROBINSON ANTHONY JOHN
IPC: B01D3/02
Filed: 1982-06-05
Abstract: With large capacity i.e. 200 litres or more, known reclamation apparatus, the inlet is small and the fluid to be treated poured into the apparatus. However, with small capacity usage, such as in a garage, it is necessary for the inlet to be relatively large so that a container e.g. oil can, of the fluid to be treated, can itself be inserted into the apparatus. To keep dimensions to an optimum, the lid or closure for the apparatus covers virtually the whole of the top of the apparatus, and the outlet is connected to the lid. To facilitate opening of the apparatus the outlet has to be flexible and this can be liable to damage and leakage. The present invention provides a solvent reclamation apparatus wherein the outlet (15) is in the form of a rigid pipe (15) which connects between the lid (3) and a condenser (17) of the apparatus (1), the rigid pipe connection (15) being pivotable to allow the lid (3) to be moved to open the apparatus (1). Thus a rigid outlet connection (15), less liable to damage, is provided. <IMAGE>
