Title: Venting a liquid supply system
IPC: F02N19/00
Filed: 1981-04-10
Abstract: A diesel engine may have an electrically-actuated cold starting device 23 in its inlet manifold 24, gravity fed with fuel from a reservoir 22 interposed in a pipe 21 for returning excess fuel from the injectors 20 and injection pump 19 to the vented fuel tank(s) 11. If the pipe 21 opens below the fuel level in the tank because the latter is full, or if oil is retained in the pipe 21 by capillary action when the tank is not full, air cannot reach the reservoir to permit fuel flow to the cold starting device when required. The reservoir outlet to the tank therefore includes a restriction 26 from which fuel emerges as a jet whilst the engine is running, and a vent hole 27 within the zone containing the jet. The velocity of the jet carries fuel past the vent hole 27 without any loss of fuel through the latter. When the engine is not running, the vent hole 27 connects the reservoir 22 to atmosphere. <IMAGE>

Title: Ball valves
IPC: F16K27/06
Filed: 1982-02-17
Abstract: A ball valve comprises a valve ball (2) which is hollow and defines an inlet (29) and an outlet (30).

Title: Manufacture of a hose mouthpiece
Inventor: SUGIYAMA KENJI
IPC: B21D53/36
Filed: 1983-03-24
Abstract: A process for manufacturing a hose mouthpiece by joining a nipple 1A to a mouthpiece body 5 having an axial nipple holding hole 6 which includes a tapered portion.

Title: Optical detection using polarized light
Inventor: HUGGINS RAYMOND W
IPC: G01N21/21
Filed: 1983-03-28
Abstract: Apparatus for detecting the presence of a transparency or thin paper (14) using a light source and a light detector. Polarizing filters (P1, P2) are placed in front of both the light source (10) and the light detector (12). When the planes of polarization of both filters are parallel, attenuation resulting from the positioning of either thin paper or a transparency between the source and detector is significantly increased making possible the detection of a transparency or thin paper. In another embodiment, if the planes of polarization are at 45 DEG , it is possible to determine whether a transparency is oriented up or down. In yet another embodiment, the planes of polarization of the filters are perpendicular. The presence of a transparency made from an optically active material results in an increase in transmission. The invention is described particularly with relevance to identifying the kind of copy material fed to a xerographic machine for control of the latter. <IMAGE>
